SHELL FILLING AND LOADING MACHINE.

Original application filed April 19, 1912,

To all whom it may concern Be it known that I, HERBERT TALLEY, a citizen of the United States, residing at J oplin, county of Jasper, and State of Missouri, have invented certain new and useful Improvements in Shell Filling and Loading Machines, of which the following is a specification. I

This invention relates to shell filling and loading machines.

The present application is a division of my application on shell filling and closing machmes, Serial No. 691825, filed April 19, 1912.

The present invention has for its objects the provision of novel means for automatically loading material, particularly plastic.

explosives such as gelatin dynamite, into paper cartridges or shells by which safeguards will be provided against undue or too rapidly applied pressure in forcing the explosive into the shells and also providing for the relatively rapid return of the parts to normal position after the filling operation has been consummated.

In carrying out the invention, 1 provide novel motive fluid pressure operated means, and novel controlling mechanism therefor, whereby the parts are placed in loading position by a more or less gradual movement as contradistinguished from a quick or abrupt movement, and, further, the extrusion or forcing of the explosive into the shells is initiated and continued in an even and regular, but not abrupt, manner, whereby too sudden or undue pressure on the explosive is prevented during loading and relatively quick return of the parts to normal position is insured, such mechanism preferably embracing, first, a bodily movable feeder or loader, means for operatingthe feeder or loader independent of its bodily movement, and means for moving it into or out of loading position; second, controlling and master or operated valves adapted to cooperate in a new manner to regulate and control the access to and relief of motive fluid pressure from the loading mechanism; third, a controlling valve and means whereby it is automatically operated by the movement of the loading mechanism; fourth, a relief valve and means whereby it is automatically operated by the movement of the loading mechanism, wherebythe density of the ex- 7 Specification of Letters Fatent.

plosive loaded into the shells is regulated; fifth, a novel controlling system for the motive fluid pressure whereby the loading mechanism 15 advanced and set into operat1on in a relatively slow manner but without undue delay in operation and is relatively quickly returned after the loading operation has been carried out; and, further,

in various features, mechanisms, pipe connections and valves arranged to carry out the objects of the invention as will more fully appear hereinafter.

In the accompanying drawings: Figure 1 is an elevation; Fig. 2, an elevation taken at the left of Fig. 1, certain parts being in section and broken away; Flg. 3, a detail view of the pilot and master valves and their connections; Fig. 4:, a diagrammatic view of the different mechanisms and the fluid pressure operating and controlling system therefor, and Fig. 5, a detail view of a certain locking device.

Serial No. 691,825. Divided and this application fllod August 18, 1912. Serial No. 714,859.

The frame consists mainly of uprights l and a yoke 2. Slidable on the uprights 1 is a carriage 3, the lower part of which carriesa feed hopper 4 which has an extended or elongated mouth 5'so that the explosive can be fed thereto and a quantity be ready for admission to the hopper as the piston makes its successive strokes. Attached to the bottom of the hopper 4 are nipples or nozzles 6. These are preferably carried by a single removable end or head which is detachably connected to the lower end of the hopper. These nipples are adapted for insertion into the paper shells which are commonly employed for containing the gelatin dynamite which the machine is adapted to load. The nipples 6 are grouped in as great a number as desired, the number corresponding to the number of shells-adapted to be held by the shell holder or shuttle and to the position of the shells therein.

The cylinder 7 is carried by carriage 3. Operable therein is a piston 8 whose rod or plunger 9 carries a forcing piston or plunger 10 adapted to operate in the hopper i and to fit it. As the piston or plunger 10 advances in the hopper 4, it forces the plastic explosive gelatin dynamite out through the nipples or nozzles 6 and into the shells. The piston or plunger rod 9 carries a crosshead 11 which is-f'slidable on the sleeves of carriage 3, the said cross-head and piston pistons being connected by rods 14 to the cross-headll. The pistons 13 have a loose fit in the cylinders 12 so that the oil contained in the cylinders 12 may gradually flow from one side of the piston to the other, this arrangement constituting an oil check whichever way the piston 8 is moving. To equalize the flow of the oil and the resistance of the pistons 13, the cylinders 12 may be connected by a pipe 15.

Carried by the yoke 2, is an operating cylinder 16 in which moves a piston 17 whose piston rod 18 is connected to-the carriage 3 in any suitable manner, the piston rods 9 and 18 being preferably in alin'ement. Oil checks embodying cylinders 19, pistons 20 and rods 21 connecting said pistons 20 to the carriage 3, serve as an oil check to prevent too abrupt upward or downward movements of the carriage 3 by the piston 17 and its rod 18. The piston 17 is adapted to move the carriage 3 downwardly to position the nipples 6 in the shells prior to the extrusion of theexplosive gelatin from the hopper 4 by the piston 10 which is operated by piston 8.

Preferably the carriage 3 and all parts carried thereby are counterpoised, so as to minimize the air or other motive fluid pressure required to operate them. Such counterweight-ing may be conveniently accomplished by providing'a shaft 22 secured to or mounted on the uprights land secured to or mounted on said shaft are sheaves 23 over which run cables 24 connected to the carriage 3 and provided with a suitable weight 25.

Rotatably mounted in or on the uprights 1 is a shell carrier 26 which is adapted for rotation to move the shell holders or shuttles 27 to their different positions. Suitable means may be provided to catch the closed and completed shells dumped from the lowermost shuttle 27, but I prefer to employ a rotatable table 28 which may be conveniently mounted on one of the uprights 1 for the reception of succeeding batches of filled and closed shells and the even distribution over its surface of the shells so that they may be conveniently and regularly removed by' hand.

The mechanisms now to be described may be mounted in any preferred position but,

ver being pulled in one direction preferably, the trip mechanism and the pilot valve are disposed on the framel or oke 2 in position for convenient trippingan manual control. v

At 107 is disclosed a four-way pilot valve which controls the operation of the entire machine. Air pressure from any suitable source is supplied to the valve casing by- "pipe 108;.109 is an exhaust branch for the with the four-way valve 107 and the'opposite end a pipe connection 112 with said,

valve 107. A lever 113 is carried by the valve and adapted for operating it, said leby a spring 114 and adapted to be pulled in the opposite direction by hand or through the intervention of a cord or chain 115 if disposed out of convenient reach of the operator. The spring 114 maintains the valve 107- in such position that air will exhaust from cylinder 110 through pipes 112'and 109 and will be admitted from supply pipe 108 to pipe 111.

At 116 is a four-way master valve which is operated by a piston 117 in cylinder 110 and a piston rod 118 connected to said valve. A suitable dash-pot 119 is connected to piston rod 118. When the parts are in the position set forth the supply of air through the pipe 111 mamtains piston 117 in such position that the four-way master valve 116 is so positioned that all the mechanisms are re.- tracted so as to be ready to perform their respective functions. I

At 120 is a latch which has an offset end 121 adapted to lock the end 122 of lever 113 (Fi 5) when said lever is raised by pulling on t e cord 115 against the action of spring 114. The latch 120 is maintained in position after looking lever 113 by a spring 123. The latch 120 may be moved in opposition to spring 123 to release lever 113 if engaged therewith by a cord 124. The carriage 3 carries a trip 125 which is adapted .to engage the latch 120 on the return of the carriage to its raised position after the shells in the shuttle have been filled, and the lever 113 being engaged with the .part 121 during the previous operation of the machine, is thereupon released so that the lever 113 resumes its normal position, placing the diflerent cylinders in communication with their exhausts. e

Referring to diagrammatic Fig. 4, the arrangement of the cylinders, their piping, valves and controlling mechanisms are therein disclosed. The spaces above the pistons 8 and 17 are connected to master valve 116 by pipes 126, the valve placing these pipes in communication with the exhaust 128 ofzthe master valve when the'parts are in normal position. The spaces below pistons 8 and 17 have pipe connections 129 and 130, both communicatlng with the pipe 131 which lea s to the master valve 116. At a suitable point in the pipe 126 is a pressure checking valve 132 of any preferred typ which momental-11y cuts down the pressure entering pipm 126 from the feed pipe 108 so that a too sudden application of pressure to the pis ns 8 and 17. will be prevented as it would result in too abrupt descent of the carriage 3 and too alarm t forcing of the explosive into the shells. n the pipe 131 there is introduced a check valve l33-whieh peremits a slow exhaust from the cylinders 7 and 16 below the pistons 8 and 17 thereof when the air is exhausting as the pistons are descending, or, a rapid supply of pressure when it is introduced via pipe 129 into the lower end of said cylinder 16 to raisethe piston therein, thus providing for a quick lifting action of the carriage '3. In the pipe 130 there is provided a pressure reducing valve 134: which, while suitably reducing the pressure, permits a comparatively quick introduction of pressure through pipe 130 be low the piston 8 sothat it may be comparatively; quickly returned upwardly after the shells have been loaded. A valve 135 in a by-pass pipe 136 permits only an exhaust of the pressure from below the piston 8; when the latter is descending to force the explosive into the shells. This valve, bychecking the exhaust from below piston 8 to a suitable extent, prevents too rapid descent of the piston 8 when the'shells are being filled.

, The pipe 126 is provided with a three-way valve 155 which controls said pipe and also an exhaust pipe 156 having a relief valve 157. The valve 157 may be of any preferred type which is adapted to be set to open at any predetermined pressure. The valve 155 is automatically operated by a rod 158 having stops 159 and 160 and it is arranged so that a bracket 161 on the carriage 3 is adapted to engage the stops 159 and 160 at different points. Pressure having been admitted into the ipe 126, the carriage 3 is forced downwar y by iston 17 to position the nipples 6 in the she ls. The piston 8 is also forced downwardly by pressure in pipe 126 so that the plunger 10 presses the explosive into the shells. At the proper point of movement, the bracket 161 strikes the stop 160, thereupon turning the valve 155 to release the pressure from above the piston 17 into the pipe 156. The valve 157 ,..according to the pressure at which it has been set to let off, determines the density of the explosive gelatin or other material forced into the shells because the carriage 3 will remain down until it is forced upwardly by the reactive pressure of the. explosive in the shells, as" the shells are filled by the plunger 10. Eventually the lift of the carriage caused by the reactive pressure of the explosive on the plungerlO due to the filling of the shells causes the trip 125 to strike the latch 120 and press it aside, thereby releasing the lever 118 whose spring 114 immediately snaps it to its normal position, whereupon the air pressure from pipe 108 passesthrough the pilot valve 107 into pipe 111, resulting in the master valve 116 being reversed. The reversal of'the master valve causes the air to pass into pipes 129 and 131 and also into pipe 130. The carriage is thereupon raised to its full height by the admission of air under the piston 17 and the bracket 161 strikes the stop 159, thereby returning the three-way valve 155 to its normal position where it is adapted to permit pressure, when entering pipe 126, to pass to the cylinder 16 on the next operation of the machine. The access of pressure through pipe 130, forces the piston 8 ulpwardly. This movementis a substantial y quick return movement.

On pulling the cord-115 or moving the lever 113 to latch it at 121, operations such as previously set forth ensue. The master valve 116 is reversed, the air is admitted into pipes 126 at checked pressure, whereby the carriage is forced downward by piston 17 to POSltlOIl' the nipples in the empty shells. The piston 8 also forces the plunger 10 into the hopper 4, forcing out the explosive into the shells.

The parts being in thepositions indicated,

the rising of the carriage due to the reac-.
