T0 L7/. whom, it may con/cern:

Be it known that I, JAMES L. BALDWIN, a citizen of the United States, residing at Ohil cago, in the county of Cook and State of Illinois, have invented a new and useful Cash and Parcel Carrier, of which the following is a specification.

My invention relates to cash and parcel carriers in which a car supporting a basket travels on a suspended track or wire and a device is provided at the end of the track to lower the car; and the objects of my invention are first to raise and lower one end of the track and control the speed of the same while lowering second, to provide a thrower for the car; third, to provide means for lowering the car at the end of the track and a governor' to automatically control the lowering of the car fourth, to afford means for holding the car in a suspended position when not in use; fifth, to have the car positively stop in front of the throwing` fork sixth, to prevent the car from leaving the track; seventh, to provide a novel locking section of the track and other objects to become apparent from the description to follow.

Heretofore there has been considerable di'l'liculty experienced in delivering the basket or basket carriers to their destination at the end of track, i. e. some were constructed with an inclined track on which the car supporting the basket would gravitate to its destination at an unsatisfactorily slow speed,

sometimes stop on the track at a point intermediate the end stations and cause delay and trouble, some were constructed with a thrower to throw the car with basket up an inclined track, this required considerable skill to land the basket at its destination, especially was this true when the same basket at different times carried goods of different weight. Still others were so constructed that the car would accidentally leave the track or the lowering device for the basket at the end of the track was inconvenient and unsatisfactory.

By the use of my invention all these difliculties are eliminated, the car with the basket is normally supported up above the head of the operator, it can quickly be lowered by the operator, raised again and forced quickly along the track with positive assurance of its reaching its destination and no skill is required in the operation.

My invention comprises a track suspended at any desired height above the floor, it is preferably a wire having its end secure-d to a piece of bar track which is pivoted to a link `or frame, provided on its extremity with means for moving up and down on a vertical support depending from the ceiling. "{jflTo the end of the bar track is pivoted to move in a vertical plane av short lock track to which is secured a rope which passes under pulleys on the vertically moving frame and over pulleys secured on the vertical support above the same and linally down to within reach of the operator. The rope is so arranged as to serve as a continuation of the track and to lower the car with the basket to within reach of the attendant and to raise it again. The same rope serves to raise and lower the vertically moving frame.

The lock track is a novel feature of my invention and serves to hold the car in a supported position when notin use.

One of the pulleys over which the rope passes is provided with a governor to regulate the descent of the car, and the car is provided with spring pressed means to prevent the car ever leaving the track.

When the vertically moving frame is in a raised position the track is elevated so that the car when pushed onto said track will travel to the remote end of said track by gravity, and when said frame is in a lowered position the track is lowered sov that the car when pushed onto said track at the remote end thereof, the car will travel by force of gravity toward the low end of the track. Besides lowering and raising the one end of the track to cause the car to travel along the track by gravity a means is provided to push the car along on the track with considerable force by pulling down on a cord. By this construction a quick andpositive acting parcel carrier is provided.

To describe my invention so that others versed-in the art to which it pertains can understand it sufficiently to make and use the same, -I have illustrated it on the accompanying three sheets of drawings in which Figure l, is a side elevation of a carrier embodying my invention 5 Fig. 2, is a section on 2 2 of Fig. l 5 Fig. 3, is a section on 3 3 of Fig. l, Fig. 4, is a section on 4 4 of Fig. 3; Fig. 5, is a section on 5 5 of Fig. 4; Fig. 6, is a side view of the car in position on the lock track Fig. 7, is a plan section on 7 7 IOO IIO

of Fig. 6 partly in elevation and Fig. 8, is a l held against that end of the slot 32 which is side elevation of the lock track.

Similar reference characters refer to similar parts throughout the several views.

The track 10 is preferably a wire h aving its one end secured to the bar track 11 so that one forms a continuation of the other and its other end secured at a station not shown which station is not necessarily a duplicate of the one shown in the drawing, and may be any of the usual kinds in which the track wire is not arranged to be raised and lowered.

.The track 11 is a casting in the form of a flat bar set vertically edgewise; it may be lightcned by having portions provided. with openings and is pivoted midway its ends to one end of a supporting frame 12 at 13 to allow the track 11 to swing in a vertical plane about said pivot. The other end of the frame 12 is provided with a longitudinally extending fork 14 which straddles the vertical support 15 which is rigidly secured to the ceiling and has a guy wire 16 connected to its lower end. Between the extremities of the fork 14 is pivoted a carriage 17 with two grooved wheels 18 arranged to travel on the support 15. The track wire 10 is always kept drawn tight by mechanism provided on the station not shown and the strain thus produced is exerted through track 11, pivot 13, frame 12, fork 14, and carriage 17 onto the wheels 18 which serves to keep said wheels constantly against the support 15.

A suitable distance above the lower end of the support 15 is secured a bracket 19 to which is pivoted a spring pressed catch 20 arranged to hook into a catch or socket 21 provided on the carriage 17 to retain said carriage and therefore the frame 12 and tracks 11 and 10 in an elevated position until the catch 20 is with drawn from said catch 21 by a pull exerted on the small wire 22 connected to the catch 20. The pull on the wire 22 may be made in any desired manner but it is preferably automatically made by the car to be described striking a lever at the other station not shown.

To the end of the track 11 remote from the wire 10 is slidingly jointed a lock track 23 to be described and to the free end of the lock track 23 is connected in the usual way an elevating rope 24 which passes under pulley 25 pivoted to bracket 26 on frame 12, thence up and over pulley 27 pivoted on bracket 19 thence down and around under pulley 28 pivoted between lugs provided on frame 12, thence up and over pulley 29 pivoted on bracket 19 and finally down to within reach of the operator.

The lock track 23 is best shown in Figs. 6, 7 and 8 its one end is vertically slotted forming the two side arms 3() which straddle over the thickened end portion 31, which is provided With ahorizontal slot 32 in which is mounted to slide a block 33 which is normally nearest to the wire 10 by a coiled expanding spring 34 interposed between the opposite end of the slot 32 and block 33. A bolt 35 is passed through holes provided therefor in arms 30 and block 33 and serves to connect track 23 to track 11.

As viewed in Fig. 8 it will be seen that the spring 34 tends to hold track 23 to the left but that it can be moved to the right about half the length of slot 32 by applying enough force to compress the spring. A short dise tance to the left of bolt 35' the track 11 is provided with laterally extending lugs or pins 36 on both sides which serve as stops for the shouldered ends 37 provided on the arms 30. It may be stated here that the lock track 23 when in the locked position shown in Fig. 8, supports the car 38 part of the time, and to relieve the bolt 35 of a portion of the supporting strain the track 11 is provided with lateral iianges 39 directly under bolt 35 for the ends of the arms 30 to rest on. Thus it will be seen that a pull down on the free end of track 23 will cause a downward pressure on the flanges 39 and an upward pressure on the lugs 36.

In operation when the car 38 is at rest on the track 23 a quick jerk on rope 24 will compress spring 34 sufficiently to move the shoulders 37 out from under the lugs 36 and the weight of the car will swing track 23 down about bolt 35 as a pivot allowing the car to travel off of track 23 onto rope 24 and then descend as rapidly as the feeding of the rope will allow.

When it is desired to restore the car to a position on the track 23 as seen in Fig. 6, the operator pulls the rope 24 down as far as possible, the last portion of the pull elevates the free end of track 23 to a point on a level with or slightly above the track 11 when the car 38 travels toward the track 11, then the operator gradually discontinues the pull on the rope 24 and the spring 34 forces track 23 to the left, as viewed in Fig. 8, and causes the arms 30 to' rest on the flanges 39 and the shoulders 37 to rest under lugs 36, which is the locked position of said track.

To assist in moving the track 23 to its locked position and to prevent the car 38 from moving off of said track 23 onto track 11 until so desired, the car is provided with a spring pressed dog 40 arranged to move laterally into and out of the `path of track 23. The dog is normally held in the path of track 23 and when the car 38 moves from rope 24 onto track 23 toward track 11 as above described the free end of the dog will contact with the squared shoulder 41 provided on track 23 and tend to move the track 23 in the same direction as the car moves which would be to its locked position.

/Vhen in position on the track 23 the car 38 cannot be pushed off of said track onto track 11 until the dog 40 is withdrawn from back of the shoulder 41 and to accomplish this, I provide mechanism mounted on the car which will automatically withdraw the dog 4() from back of the shoulder 41 when the propelling mechanism is made to act on the car.

The car 38 which is best shown in Figs. 1, 6 and 7 has the two grooved wheels 42 pivoted between the frames 43 and 44 arranged to travel on the tracks 10 11 and 23 and the rope 24. The frame 44 extends from above the track where the wheels 42 are pivoted down to a short distance below the track where the bails 45 of the basket 46 are attached while the frame 43 does not extend below the track so as to allow the car to pass the track supports. The frames 43 and 44 are securely fastened together by the screws or bolts 47.

An inverted V shaped arm 48 is pivoted to the frames 43 and 44 at 49 with its apex extending'some distance above said frames to be contacted by the propelling fork 50 which is mounted to slide on the rod 51 located directly above and parallel with track 11 and secured in position by having its extremities fastened in the brackets 52 and 53 which are secured to the ends of another rod 54 which is supported by braces 55 secured to track 1 1 as shown in Fig. 1.

The normal position of the fork 50 is back adjacent the bracket 52 and to move it forward on rod 51 toward bracket 53 a cord 56 is attached to the fork 50 preferably at a point above rod 51. The cord 56 extends forward from the fork 50 around pulley 57 pivoted in bracket 53, thence up and back over pulley 58 (Fig. 3.) pivoted to bracket 19, thence down under the floating pulley 59 pivoted in a suitable frame 60, thence up and over pulley 61 pivoted to bracket 19 and thence down having its end secured to the frame 60. Thus it will be seen that when the frame 60 is pulled down the fork 50 will be moved from adjacent the bracket 52 toward bracket 53 and during its movement it will contact with arm 48 and propel the car 38 along the track. The arm 48 is provided with an extension 61 below pivot 49 adjacent frame 44 arranged to contact with a tailpiece 62 of the dog'4() in such manner that arm 48 will be swung about pivot 49 and withdraw dog 40 from back of the shoulder 41 when said arm is moved by fork 50. A cord 62 is attached to the frame 60 which hangs down far enough to bring the handle 63 attached to the lower` end thereof within reach of the operator. Vhen the handle 63 is pulled down the fork 50 is forced against the arm 48 and tends to move the car 38 out toward wire 10, but the car cannot begin to move until dog 40 is withdrawn as described, after which a further downward pull on handle 63 will propel the car out along on tracks 11 and 10 to its destination.

In operation the car 38 is never propelled out onto the track 10 excepting when the frame 12 is in its raised position, being retained by the catch 2O engaging the shoulder or catch 21, and after the car has been propelled away from the station by pulling down on handle 63 the propelling fork 50 remains in its operated position near the bracket 53 until it is returned to its normal position.

Before returning the car to the station,l from the station not shown a pull is applied on wire 22 which allows frame 12 with its connections to lower by gravity, and I prefer to have the lowering of frame 12 return fork 50 to its normal position adjacent bracket 52 by attaching one end of a cord 64 to the fork 50 and passing it back under a pulley 65 pivoted to bracket 26 on frame 12 thence upward around pulley 66 pivoted in bracket 19 and finally down and through a perforation in frame 12 below which a stop 67 in the shape of a ball is secured to the cord 64.

Assuming the frame 12 to be in its raised position and the fork 50 near the bracket 53, when the frame 12 is released and moves down it will of course carry the stop 67 down with it and thus pull the fork 50 back to its normal position. that as the fork 50 is returned to its normal position the cord 62 and handle 63 are raised to their normal position leaving all the parts in position for another operation.

When the car 38 is on its return trip toward the station it travels at such speed that when it leaves the track 23 and passes onto the rope 24 its momentum will cause a pull on the rope 24 away from track 1 1 stron-g enough to unlock track 23 from track 11 and its weight will cause said track 23 to swing down about its pivot 35.

When the car is on track 11 or 10 it sometimes happens that it leaves the track and thus causes damage and delay, therefore I prefer to provide means whereby the car is absolutely prevented from ever accidentally leaving the track. This means comprises the downwardly curved fingers 68 extending from the frames 43 and 44 at each end of the car terminating slightly beyond the wheels 42 and about on the same horizontal plane as the lower edge of wheels 42, and the upwardly curved fingers 69 pivoted to the frame 44 below and on either side of the track which are spring pressed upwardly andarranged so that their ends will normally engage the ends of the :lingers 68.

To assist in keeping the car on the track, and to move the fingers 69 down about their pivots to clear the supports secured to track 11 grooved wheels 71 are pivotally mounted between the pair of Afingers 69 at each end of the car. The fingers 69 at the one end of the It will be understood IOO IIO

car may be provided with the extensions 72 which are connected across by a pin or roller 73 which serves to snap under a hook provided Aon the station not shown to prevent the car from rebounding.

To -secure the bails 45 of the basket to the car l `have shown the clamps 74 provided with a socket to lit over the tapered extension 75 of the frame 44, with a bolt 76 to secure them together. A cap 77 is bolted down over the bent ends of the bails 45 which rest in a groove provided in the clamps 74, and the lugs 78 on the clamps 74 prevent the bent ends of the bails 45 from being withdrawn longitudinally.

Some kind of a propelling device is preferably provided at the station not shown which has a fork similar to fork to act on the arm 48, but of course it will move the arm in an opposite direction to which it is moved by fork 50 5 and when the arm 48 is thus moved about its pivot 49 the pin or roller 73 is moved down and out of engagement with its cooperating hook mentioned above for the reason that the extension 61 of the arm 48 is connected to the vertical extension 79 of the finger 69 by the link 80. Stops 81 and 82 are provided on the upper part of frames 43 and 44 to limit the movement of the arm 48.

Some one of the pulleys over which rope 24 passes has its speed controlled by a governor and in the drawings it is shown as being the pulley 29.

Referring more particular to Figs. 3, 4 and 5 the pulley 29 is mounted to rotate loosely on a pin 83 secured in bracket 19 and having on its outer end the lock nuts 84 and washer 85. The pulley 29 is provided on one side with the conical surface 86 concentric with pin 83 and on the other side with the ears 87 to which are pivoted the' arms 88 carrying the governor balls 89. The arms 88 have the short extensions 90 with their rounded ends resting against the washer 85. Mounted` loosely on the pin 83 between pulley 29 and bracket 19 is a sleeve 91 provided with a conical end 92 concentric with pin 83 and arranged to fit onto the conical surface 86 of the pulley 29. A spiral expanding spring 98 'is .interposed between the pulley 29 and sleeve 91 to normally separate the conical surfaces 86 and 92.

The rotation of the sleeve 91 on pin 88 is positively prevented in one direction by the lug 94 on the sleeve contacting with the lug 95 on the bracket 19. The sleeve 91 is also provided with a radial arm 96 which serves to press the rope 24 tightly into the groove of the pulley 29 when it rotates swiftly in the direction indicated by the arrow in Fig. 4, by

cooperating with mechanism to be described. A bell crank lever 97 is pivoted to the bracket 19 having one arm 98 extending into the path of the arm 96 and the other arm 99 provided with a flanged pulley 100 arranged to constantly hold the free end of rope 24 in the groove of pulley 29. The extreme end of arm 99 is provided with a loop 101 to guide the rope 24. The arrangement of the bell crank lev'er 97 with relation to pulley 29 is such that when the lever 97 swings on its pivot the pulley 100 will move toward or away from the pulley 29. A coiled expanding spring 102 is interposed between the free ends of arms 96 and 98. ln operation the pulley 29 is rotated in the direction indicated by the arrow in Fig. 4, either by the lowering ofthe frame 12 or by the lowering of the car 38,' in either case the mechanism just described will control the speed at which they will fall. l

When the pulley 29 is swiftly rotated the governor balls 89 which rotate with said pulley will by reason of the centrifugal force move the arms 88 about their pivots so as to force the extensions 90 against the washer 85.

The washer 85 being held against movement by the nuts 84, the surface 86 will be pressed against surface 92 and the friction thus created will tend to revolve the sleeve 91 in the direction indicated by the arrow in Fig. 4, and as the sleeve 91 revolves its arm 96 will act through the spring 102 and bell crank lever 97 to move pulley 100 toward the pulley 29 and insure a more secure grip between the rope 24 and pulley 29.

' It will be understood that numerous changes may be made in the construction and form of the several parts without in the least departing from the spirit of the invention.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent of the United States is 1. In a parcel carrier, a basket, a track arranged to be raised and lowered for said basket to travel on, a propelling mechanism for propelling said basket along the track and means for lowering the basket.
