FILLING DEVICE.

Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed September 5, 1902. Serial No. 122,166.

The invention relates more particularly to 3 devices used for filling bottles, casks, and the i like.

One of the objects of the invention is to provide an improved siphon filling device in which communication between the exhaustopening for the air and the siphon is automatically interrupted when a flow of liquid has been established.

The invention further designs to provide improved means for automatically cutting off the liquid-supply when the vessel has been filled.

A. further object of the invention is to provide an improved construction of filling-tube, and, lastly, the invention designs to provide an improved filling device and an improved construction for the several parts thereof.

With these objects in view the invention consists in the several novel features of construction hereinafter set forth, and more particularly defined by claims at the conclusion hereof.

In the drawings, Figure I is a view in central vertical section of a device embodying the invention. Fig. 2 is a similar view, the parts being shown in position assumed when the device is in operation. Fig. 3 is a detail view, in vertical section, taken on line 3 of Fig. 1. Fig. f is a viewin horizontal section taken on line I of Fig. 2. Fig. 5 is a detail view of the filling-tubc in horizontal section, taken on line 5 of Fig. I. Fig. 6 is a view in side elevation of a device embodying a modified form of the invention. Fig. 7 is a view of the same, illustrating the parts in another position. Fig. b is a detail view of another modilication.

A casing of suitable construction comprises a base If) and a body 12, secured to the base. A screw-tlneaded ring 13 engages an annular projection is on said body and removably secures the casing-sections together. Base 10 is provided with an inlet 11, with which the liquid-supply is connected. A filling-tube 15 is secured to base 10 and communicates with a chamber If) within the casing. The fillingtube conducts the liquid from the casing to Body I2 the bottom of the vessel to be filled.

is usually provided with eyes 17 or other means whereby it may be conveniently suspended.

In many instances it is desired to employ a siphon filling device, and one object of the invention is to provide means for automatically interruptingcommunication with the exhaustopening and the liquid-supply when flow of the liquid has been established. When the device is employed as a siphon, the casing is provided with an exhaust-opening l8 and a float 19, which operates a valve 20, adapted to engage a valve-seat 21, formed in the easing-body. Ribs 22 guide the float vertically. Exhaust-opening 18 is usually formed within a mouthpiece 23, of such shape that the operator can place the tube to his lips and draw the air from the siphon conductor and the valve-casing, so that liquid from the source of supply will flow to chamber 16. If desired, a pump can be attached to mouthpiece 23, as well understood in the art. Thcobjcct in providing this automatic cut-off is to prevent the liquid from passing to the mouth of the operator or passing to any other means for exhausting the air which may be employed. As soon as the liquid passes into chamber I6 the liquid will lift float 19 and shift valve 20 against valve-seat 1. Communication will then be interrupted between the inlet for the liquid and the exhaust-opening for the air, so it will be impossible for the operator to draw the liquid into his mouth. Float I9 is secured to a stem 2%, which is provided with a scrmv-thread. When it is desired to retain the float in lifted position, so the siphon can be continuously operated without the necessity of starting the flow of liquid for each filling operation, the float may be retained in lifted position by a cap 25, which is provided with a screw-threiuled socket adaptcd to engage the screw-thread of stem 2% and is also adapted to engage mouthpiece 23 and firmly secure valve 20 in lifted position and against valve-seat 21.

The invention also designs to provide an improved cut-off mechanism whereby the supply of liquid to the bottle or other vessel may be discontinued at any desired time. Such mechanisi'n comprises a valve 27, secured to a stem 28. Valve 27 engages a valve-seat 29, formed in the bottom of base IU of the casing and controls the flow of liquid to the filling-tube. A portion of stem 28 is extended upwardly from valve 27 and is guided in a socket 230, formed in the lower portion of ed in balanced position with respect to the mechanism for shifting the cut-off. Valvestem 28 of the cut-01f is ad justably connected by screw-thread 32 with a sleeve 34 of an airvalve 33. Alock-nut 35 secures stem 28 and sleeve 34 in assigned relative position. Sleeve 34 is extended through a tubular guide 36, which is rigidly secured to the filling-tube and which is provided with a valve-seat 37 ,of elastic material, and an air-duct 38 is formed between guide 36 and sleeve 34 of the cut-off valve. A loose fit between sleeve 34 and guide 36 is suflicient to provide the desired air-passage. Valve 33 controls the admission of air to the filling-tube. WVhen the valve is in lower position, seen in Figs. 1 and 3,) air can pass through duct 38 to the filling-tube so the said tube will be drained and the contents thereof be discharged. When the valve is in position seen in Fig. 2 and the device is in operation, valve 33 will be in closed position.

The mechanism for automatically operating cut-ofl' 27 and air-valve 33 comprises a bail 39, provided with a ring portion which encircles sleeve 34 and with vertical arms pivotally connected, as at 42, with a lever 43, which is pivotally sustained, as at 44, in lugs secured to the filling-tube. Lever 43 is preferably bifurcated, as shown, and has pivotally connected thereto, as at 46, a supplemental lever 47, to which is pivotally connected, by a pin 48, a pendent link 49, to the lower end of which is connected a float 50. Lever 47 is preferably provided with a cylinder 51, in which a guideway is formed for a weight 52. Lever 47 is formed to fit between the sides of lever 43, and a portion thereof is adapted to rest upon lever 43 while the parts are in position seen in Fig. 2. Lever 43 is provided with a stop 55, .which restricts the swing of lever 47 in one direction. Lever 43 is preferably provided with a screw-threaded extension 56, and a counterweight 57 is adjustably secured therein, whereby the relative weight of the parts of the cut-ofi-operating mechanism on each side of lever-fulcrum 44 may be varied. The cutoff-operating mechanism is constructed so the preponderance of weight is on that side of lever-fulcrum 44 on which cut-off is located-21 0., so the normal tendency of the valve is to remain closed. WV eight 52 is arranged to travel on both sides of the fulcrum of lever 47, so its force will be differentially applied-2'. a, when the cut-oif-opcrating mechanism is in position to close valve 27 the gravity of the weight will tend to swing lever 47 about its fulcrum and lift the float and will also be indirectly applied to lever 43 at a point so close to the fulcrum of lever 43 that the ponclerance of weight on the valve side of lever 43 will readily overcome the force of all ofthe parts on the opposite side of lever 43, and when the mechanismis in position seen in Fig. 2 the gravity of weight 52 will be applied at a point farther from fulcrum 44, and so the preponderance of weight is then on the float side of lever 43. Guide 51 is arranged to occupy an inclined position when the cut-off valve is open and such as will cause weight 52 to quickly roll to the opposite side of pivot 44 and shift the preponderance of weight as soon as float 50 is lifted by the liquid within the vessel being filled. The purpose in employing this construction of valve-shifting mechanism is to provide a mechanism which is controlled by a float which is necessarily of limited size, because it must be inserted through the mouth of the vessel to be filled, and which mechanism is sufliciently sensitive to respond to a slight movement of the float and which when slightly shifted will quickly and positively close the cut-ofi, and thus result in effecting the shift of the cut-off when the liquid column in the vessel reaches the desired height and results in filling the vessels to a uniform height.

The diameter of the filling-tube is necessarily restricted to the size of the mouth or opening in the bottle or vessel to be filled, and therefore it is of importance to provide a construction in which the flow of liquid is not materially interfered with, so that the flow of liquid will not be retarded and so the vessel will be quickly filled. In order to provide a construction of tube in which a float can be held and in order to provide a channel through which the displaced air within the vessel can be discharged therefrom, the tube is preferably of the construction shown. The upper portion of the filling-tube 15 is preferably provided with a connecting portion and with a lower vertical portion 61. A tube 62, eccentrically arranged within the vertical portion 61 of the filling-tube, forms a guide for float 50. The walls of tubes 61 and 62 are cut away to form a vertical slot 63, which affords communication between the chamber within the vessel and the chamber within tube 62 and also to provide an exit for the air. As the liquid rises in the vessel it will pass into tube 62 and maintain a corresponding column in tube 62, and, furthermore, the air within the vessel will pass through the slot 63 and out of the upper open end of tube 62. In practice this construction of filling-tube has been found to be efflcient and positive in operation. It will be observed that by providing tube 62 around float 50 the downwardly-passing liquid does not contact with the float and the operation of the float will be uniform regardless of rapidity of the flow through the filling-tube. l

The operation of the improved filling device will be as follows: Assuming the flow of liquid to have been established between the source of supply and chamber 16, as hereinbefore described, and assuming the parts to be in position shown in Fig. 1, the operator will depress pin l8 until the parts assume the position seen in Fig. 2. lever it" to swing into position to lower float t) and to shift lever l3 into position to open valve 27, and thus establish a flow of liquid to the filling-tillaand into a vessel to be filled. 'hen lever 7LT has been shifted, weight will travel into position to apply its force ata point where it will overcome the normal preponderance of weight on the valve side of fever l3, and the weight w1ll be on that side of lever-fulcrum l6 on which it will permit the float to remain in lower position and so the float will be free to be lifted by the liquid column. So long as the parts remain in such position the flow of liquid through the fillingtube and into the vessel will continue. \Vhen valve 27 is opened, air-valve will be closed, and vice versa, so that while the supply of liquid continues air or liquid cannot pass through duct 38. When the liquid within the bottle or vessel being filled has reached the desired height, float 5t) will be lifted. A slight upward lift of float will tilt lever l7 sufficiently to cause weight to travel to the opposite end of guide 51 and there differentially apply its force to assist the rising liquid column in lifting the float and at a point with respect to fulcrum 4a at which the pre tondcrating weight of the valve will cause it to be quickly closed, so the valve 27 will cut off the further supply of liquid. Simultaneously with the shift of valve 27 airvalve 3 will be shifted to permit air to pass into the upper emf of the filling-tube, so that when the tube is withdrawn from the liquid column in the vessel the liquid column will not be held in the tube until the tube has been withdrawn. but will quickly pass into the vessel. It will be observed that when the float has caused the shift of the valve-opcrating mechanism the parts will be positioned Such shift willcause of lever t3 so they will beheld or locked in position to retain valve 2T closed. because the force of float so is applied close to fulcrum t and the force of weight 52 is applied at a point where it cannot overcome the normal preponderance of the valve side of lever i3. Such construction automatically holds itself in assigned positions J. 1 when it is shifted in either of its positions it will be held there until again and rcversely shifted.

Thus it will be seen that the invention pro- 1 vides a mechanism whereby the liquid-supply is automatically discontinued and which respends quickly, positively, and uniformly to the liquid column in the vessel and in which air is supplied to the filling-tube, so the liquid therein will quickly pass in the vessel while the tube is being withdrawn from the vessel.

The invention is not to be understood as restricted to the details shown and described, but may be modified by the skilled mechanic without departing from the spirit of the invention. So, also, the several features thereof may be employed severally without adoption in entirety. For example, in Figs. (3 and T there is shown a modified form of the invention. In this form a supplemental lever 4:7 is pivotally sustained bya support 65, rigidly secured to the filling-tube. Weight-guide 51 is provided with a lug 66, positioned to engage an adjustable stud 67, formed on the.

valve-opcrating lever i3 when valve 27 is in open position, and securely hold the lever, so as to cause the valve to be held in said position. Said lug and stud are positioned to free lever 43 upon a slight shift of lever 47 by float 5f). Leverii is also provided with a stud 68,which will engage a cam projection til) during the shift of lever ii in that direction in which said lever is shifted by float 50. When the lever i5 has been shifted to close valve .27, the force of weight 5; will be applied to lever at? on that side of fulcrum (36, which will hold lever 47 in position to bring stud 68 under projection (ii) of fever 1-3 and lock the lever in position to keep valve 27 in closed position. A. finger-piece U4 is secured toguide 5t, and thereby the lever H can be conveniently depressed. Pivot-pin in is extended laterally to engage the under side of lever 13 and restrict the independent travel of fever i3 and insure the passing of stud (38 beneath cam ('55). The operation of this form will be as follows: Assuming the parts to be in position to hold valve 27 in closed position, stud ($8 of lever ti will be in position adjacent cam (it) and will thus insure the retention of the parts insuch position. (See Fig. i.) \Vhen the device is to be operated, levers l3 and f7 will be depressed by the operator until the parts assume the positionshown in Fig. t During the latter portion of such shift weight 5; will pass to the outer end of guide 51 and tend to depress the outer end of fever l7 and stud (57 will pass beneath lug (3ft. 'lhese parts will then be locked in position to hold valve 27 open (see Fig. (3) and will remain there until the vessel has been filled, when float 5f.) will tilt lever sf? sufliciently to cause weight 52 to travel to the inner end of lever JCT, aml thus effect a sudden shift of said lever. During the initial portion of such shift of fever 4t? lug (ill will pass away from stud UT and release lever 45%, and during the latter part of such shift stud (38 will pass beneath cam (it), and thus secure the lever mechanism in position to retain the valve in closed position.

In Fig. 8 there is shown another modified form of the invention and in which the differential mechanism comprises a weight 70, which is secured to travel with a lever 47 and is arranged to cross the line of gravitation, so that its force will be differentially appliedc'. 6., on opposite sides of fulcrum a6 of lever &7'and so it will tend to hold the lever mechanism in both positions. Lever L7 is also provided with a counterbalance 71, which assists the float in overcoming the force of weight 70. In operation the parts will be in position shown in Fig. 8, when valve 27 is open and weight will be arranged to lock lever 43 in assigned position. A slight shift of float 50 will cause weight 70 to cross the line of gravitation and then tend to reversely .tilt lever 47 and to bring the other parts in position to retain the parts in position to hold valve 27 in closed position. It will be understood that the construction of the other parts will be the same as the construction of the corresponding parts shown in Figs. 6 and 7.
