SPECIFICATION forming part of Letter.; Patent No. 764,202, dated July 5, 19.04.

Applicationlerl September 24, 1903. Serial No. 174,427. (No model) To {LZ whom it may cm1/cern:

Be it known that I, VILLIAM J. NEWMAN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Removing Dirt from Excavations; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to thc accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

rlhis invention relates to improvements in apparatus for removing dirt from excavations, such as the cellar-way or basement of a building, preparatory to constructing' the building and delivering it to wagons or other vehicles by which it is removed from the premises; and the invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

A complete apparatus in which my improvements are conveniently embodied embraces, in general terms, an inclined or sloping' track extending from the bottom of the excavation to'a point outside or on thc bank thereof, a dumping car or cars traveling on said track, a structure or frame located outside the excavation upon which the upper or outer end of the track is supported, means on or at said frame for dumping said car, a passage-way beneath said frame into and through which a wagon or other vehicle may pass to receive the dirt dumped from the car, and a plurality of branch tracks laid on the bottom of the excavation and so disposed that cars -on said track are accessible for filling from dierent parts of the excavation, said tracks being` so` arranged relatively to the foot of the sloping track that the dumping car or cars may be readily transferred from any of said branch tracks to the foot of the inclined track, and a cable operating from a central point located at the foot of the sloping track to draw the cars upwardly from the branch tracks to the sloping track, from whence said car or ears may be drawn up the sloping track to the dumping apparatus outside of the excavation.

The present invention relates more specifically to the arrangement of the parts inside of the excavation, and such parts may be used with elevating and dumping apparatus of a kind differing from that herein shown.

In the drawings, Figures 1 and l, contained on Sheets l and 2, is a view partially in side elevation and partially in section, the section being taken on linel l of Fig. 2 of an apparatus made in accordance with my invention, showing the part thereof located -outside the excavation and the part inside the excavation and the inclined track connecting the same. Fig. 2 is a fragmentary top plan view of the parts of the 'apparatus located within the excavation at or near the foot of the inclined track. Fig. 3 is a fragmentary side elevation of a part of theapparatus located inside the excavation, taken on line 3 3 of Fig. 2. Fig. i is a top plan view showing the arrangement of the tracks in the yexcavation.

As shown in the drawings, Adesignates the inclined or sloping track, which extends from the bottom of the excavation to the structure or frame on the bank thereof, which supports said upper end of the track A, the dumping apparatus, and a guide-hopper C and is arranged to afford beneath the same a passageway for a wagon D or other vehicle to receive the dirt dumped from the car through the -guide-hopper C and convey it from the premises. B designates a dumping-car which travels on said track A and which is filled with dirt in the excavation and thereafter drawn upwardly therefrom on said track A to the dumping apparatus.

The parts just described are generally like the same parts of the apparatus shown in my prior application for United States Letters Patent, Serial No. 158,594, filed May 25, 1903, with the exception of minor deviations in the structural details of the car and dumping apparatus. The front and rear wheels B B2 of the car travel on the track A, and said car is open at its front and top, the front end thereof being closed by a door B, which is attached to a swinging frame which is hinged at its rear end to a transverse shaft-B,y extending transversely across the rear end of the car, as in the ca r shown in my said prior application. The shaft B5 is extended beyond the swinging IOO frame B" and is provided at its outer ends with rotative wheels I, which are adapted to strike inclined defleetor rails or bars E E, located laterally outside of the track and supported at their lower ends on the sloping' track and on their upper ends on said upper frame or structure, as in my prior construction referred to, whereby the car is dumped as it reaches said frame. A difference between the dumping-car herein shown and that of my said prior application is that said wheels which engage the deflector or dumping bars E, are journaled on the shaft B instead of being' journaled on the shaft of the rear wheel B2, as in the construction of my aforesaid application. The cable F, by which the car is drawn up said sloping' track, .is attached by chains f to the swing'ing' frame B" and is trained over pulleys F F2 and thence to the drum of a hoisting'- engine. (Not shown.) In the present construction the upper bars 7/ of said swinging door-frame are connected with the door by means of a transverse rod b2, which extends removably through forwardly-directed flanges /j on the door. Said flanges are provided with two or more holes, through either of which said rod may extend, whereby the upper bars may be shifted downwardly at their outer ends with respect to said door. The lower bars 7)" of said swinging door-frame have slotted connection at their rear ends with the upper bars, as shown in Fig. l, and are loosely connected at their forward ends with the lower side of the door, thereby permitting' such relative movement of the upper bars to the door.

The adjustment of the upper bars of the door-frame to the door in the manner described is provided in order to enable the car to be drawn up tracks of differentinclinations and at the same time avoid tendency of the draft on the front end of the car lifting the rear end of the carl off the track. When the track has a greater slope or inclination than shown in the drawings, the upper bars of said door-frame are moved downwardly into their lower positions. lf desired, the wearingirons c, with which the deflector-bars E are faced, may be turned upwardly at their upper ends, as indicated at c', to constitute stops to prevent the car from being' pulled entirely ofi the deflector-bars when it is being dumped.

'lhe operation of drawing the car up the sloping track and dumping the contents thereof into the hopper C and thence into the vehicle D below is sul'istantially thc same as that set forth in my prior application and need not be further described.

Located at the bottom of the excavation are a plurality of tracks, which cover the same in such manner that dirt from all parts of the excavation may be conveniently loaded directly in the car or cars on said tracks, and means are provided whereby by the use of a single cable (preferably operated from the drum of a hoisting-engine outside of the cxcavation and worked from a center located at the foot of the sloping track) loaded cars maybe transferred from any of said tracks to the sloping track and empty cars from the sloping' track to the branch or excavation tracks. I have shown herein one convenient arrangement for effecting' this result, though it will be obvious from the foregoing that the details of the arrangement may be varied. The arrangement illustrated will now be described.

Located at the bottom of the sloping track A is a track G, extending' transversely from one side of the excavation to the other. Said track is located in a depression below the level of the foot of the track A, as clearly shown in F ig'. la. Traveling on said track is a transfer-carriage H, made of open framework construction, as more clearly shown in Figs. 2, 3, and 4, and having flanged wheels t, which travel on the rails of the track G. Supported on the top of said transfer-carriage is a short track consisting of parallel rails /r 7M, and the level of said track (nl is such relatively to the level of the foot of the track A that the said track-rails /z/ are at the level of the track-rails A and when said carriage is standing' opposite said track A permit a car to be moved from the transfer-carriage to the track A, and vice versa. Extending in opposite directions from the transfertrack G are a plurality of branch tracks I, laid in the bottom or Hoor of the excavation, the outer ends of said branch tracks extending to the sides of the excavation and at right ang'les to said transfer-track, as herein shown, though the directions of the said branch tracks may be varied. The branch tracks I are laid at the same level as the foot of the sloping track, the inner end of which latter is horizontal, so that cars may be transferred .from the carriage H to either and all of said branch tracks, and vice versa. The tracks l and horizontal part of the track A will preferably when first laid be set somewhat below the gcneral level of the excavation-floor and will be lowered, as will the track as the dirt is removed from the excavation. As herein shown, two of the branch tracks I are located on the same side of themain track G as the track A, while four are located on the other side thereof.

The means provided for drawing the car or cars B from the outer ends of the several branch tracks to the transfer-carriage and for thereafter drawing the transfer-carriage loaded with one of the cars B to the foot of the sloping' track are made as follows: J designates a cable which is preferably trained over a drum of the same hoisting-engine by which the cars are drawn up the inclined or sloping track and is trained about two sheaves K K, supported on a frame L, located at the foot ofthe sloping track A. Said cable is provided at its free end with a hook, by which it is connected with the carriag'e H. The sheaves IOO IIO

K K are disposed with their axes of rotation in planes perpendicular to the track G and are rotatively mounted on shafts 7c, depending from a cross-bar L of the frame L. Said frame comprises four vertical posts L2 L2, arranged at the corners of a rectangle, as herein shown, and connected at their upper ends by longitudinal side members L3 L3 and transverse end members Li L4. Said beam L is herein shown as parallel with said side members and is attached at its ends to said end members L". The frame is further strengthened by means of a central transverse member L5, parallel with the transverse end members. Arranged opposite to the ends of the braneh tracks I, adjacent to the transverse track G, are a plurality of posts M, one for each branch track, and each post is located on the side of the transverse track Gremote from its associated branch track. The posts M are surmounted by rotative pulleys or sheaves m.

The operation of drawing a loaded car from one of the branch tracks and transferring it to the transverse track G and from thence to thc foot of the sloping track is as follows: It will be understood that the cable J remains trained between the sheaves K K at all times and that it travels in contact with one or the other, depending upon toward which end of the track G it is directed. A car after having been dumped in the manner shown in Fig. l, Sheet l, and after it has been allowed to travel gravity down the sloping track to the transfer-carriage at the foot of said track is moved by hand or otherwise, together with the transfer-carriage H, to the inner end of one of the branch tracks I, and thereafter the dumpingcar is transferred to that branch track and is moved to the point on such track at which it is to be loaded. After the car has been loaded the free or hooked end of the cable J is carried laterally along the track Gr toward thc branch track on which the loaded car is located and is trained over the pulleys m of that post M which is located in line with the said branch track containing the loaded car and is thence carried to the loaded car and connected with the said car. Preferably the hook j, of said cable is hooked into an eye b located at the rear end of said dumping-car, as shown in Fig. 4., The hoisting-drum is now started and moves the car inwardly on the branch track and carries it upon the track of the transfer-carriage which has been placed opposite said branch track. Thereafter the cable J is disconnected from the dumping-car and the hook thereof engaged with a hook h2 at the rear end of the transfer-carriage. The cable is then released from the sheave m, about which it was trained while the loaded car was being drawn to the transfer-carriage, and its drum is rotated to take up the slack of the cable between the carriage and central sheaves K, and thereafter in the continued rotation of said drum the transfer-carriage is drawn by said cable to the foot of the inclined or sloping track. The attachment of the cable J to the rear end of the transfer-carriage enables said carriage to be drawn entirely loeneath the sheave-frame L and in line with the rails of the track A. After the transfer-carriage has been in this manner brought opposite the lower end of the sloping track A the cable F is connected with the dumping-car, and said dumping-car is thereby drawn up the sloping track to the frame C and the contents thereof dumped in the manner shown in Fig. l. It will be observed that when the dumping-cars B are drawn inwardly from the branch tracks which extend parallel with the sloping tracks said cars are drawn backwardly and are drawn forwardly from the branches on the other side of the transverse track G toward said transverse track.

With the construction shown it will be observed that as many dumping-cars may be employed as there are branch tracks and that one loaded car may be drawn to the transfer-carriage and from thence transferred to the slopying track, from whence it is carried to the dumping apparatus while the other cars are being filled, and that immediately after one car has been dumped and returned to the excavation another loaded car may be transferred to the sloping track, and in this manner, if a sufcient force be employed to keep said cars filled, the apparatus may be constantly operated to draw the filled cars up the sloping track to the dumping apparatus.

In Fig. 4 I have shown in full lines the cable J arranged to draw a loaded car from one of the branch tracks to the transfer-track and in dotted lines arranged to draw a loaded car from an opposite branch track to the transfer-track, the manner of training the cable J over the sheaves m being thus clearly illustrated.

In lieu of the transfer-track G shown I may employ a central turn-table located at the foot of the sloping track, and in this event the several branch tracks may extend radially from the turn-table instead of being arranged as herein shown.

Other changes in the structural details may be made without departing from the spirit of my invention, and I do not wish to be limitedto the details shown except as hereinafter made the subject of specific claims.
