39 Claims.

The invention relates generally to a method and machine for placing a measured quantity of a pasty mixture into a receptacle. This problem arises in one instance, for example, in the placing of a priming mixture into a shell or priming cup and particularly into the conventional rim fire shell. t is necessary that an arcuate amount of the mixture be placed in each shell and that it then be put into position in the rim of the shell. One method of doing this has been to put the priming mixture, which is in a pasty form, into the empty shells while the are held in a suitable frame and then to remove the shells from the frame by hand and place them on a rotating table. The table carries the shells containing the loose priming mixture to a clamping means which holds the shells while a suitable means, such as a spinning element, puts the priming mixture into its permanent position in the rim of the shell, as seen, for example, in the U. S. Patent to Olin (No. 887,508).

This method has many disadvantages, which include the danger of the shells overturning and spilling out the loose priming mixture, and the handling of the shells between the charging means and the means to place the mixture into its final position.

One of the objects of the invention is to provide a method and means of loading a pasty or wet mixture into a receptacle, it being understood that the method and means employed are suitable for general application and not limited to the art of priming cups and shells.

Another object is to provide a method of measuring a definite quantity of a mixture which can be subsequently placed into a receptacle.

A further object is to provide a means for feeding, guiding, and positively engaging the receptacles to be filled until the material to be placed therein has been permanently put into position therein and to reduce the amount of handling of the receptacle.

A further object is to provide a machine that will be safe to operate and will prevent the loss of the material to be loaded into the empty receptacle.

A further object is to provide a machine that is readily adjustable and can be adapted easily to various types of receptacles and quantities of mixture to be placed therein.

There are many other objects too numerous to mention that will become apparent in the ensuing description, .and it is to be understood that the preceding listof objects is not to be construed as restrictive.

The forms and embodiments he einafter shown are merely examples of ways in w ich the invention may be carried out, and it i to be understood that the number of recept cles operated upon can be varied by changing he index and drive ratio means of the various pa ts.

A general description will first be given of one specific embodiment of the invention which is shown in assembled form in Fig. 1. Merely by way of example, the invention is described in conjunction with operation on conventional rim fire shells such as the .22 caliber, it being understood, however, that any type of shell or receptacle may be operated upon, it being merely necessary to change the feeding means to accommodate the shell. In Fig. 1, the plate type of charger is disclosed embodied in the machine;

however, the serrated disc type of charger, de-

scribed later, may be substituted for the plate type of charger. A driving motor (not shown) is located underneath the machine. This motor may be of a conventional type containing a mag-- netic brake which is released when the motor is energized, it being necessary that the machine:

come to rest, promptly upon stopping. The main driving motor drives a shaft located at the rear;

of the machine through the pulleys 5! (Fig. 1). At 5| the shells may be picked up from a hopper located at the right of the machine by an endless belt having shell lifting projections and caused to fall onto a guiding means 5'2 which guides the shells to an inverting device 53, the

shell being base upward in the guiding means. The shell inverting device is driven by suitable cam means in such a manner that it delivers two shells to the shell advancing screw 54 for each revolution of the main shaft. The screw thread means 54 moves the shells to the left in a row.'

Advancing means having projections for engaging the shells can be used in place of a screw thread means, and screw thread means where it appears is to construed broadly enough to include such. The charging plate 55 has transverse and longitudinal rows of apertures, and in the operation of the machine, the apertures 55 in the removable charging plate 55 have previously had a priming mixture rubbed therein. The charging plate 55 is mounted on a carriage. 98 which is moved transversely of the screw thread feeding means 54 by suitable indexing means. Located within charging punch head 58 are a group of reciprocating punches which are adapted to enter the apertures 56, thereby pushing the priming mixture contained in the apertures 56 of plate into the rows of shells which have been carried underneath the apertures by the screw thread advancing means 54. Upon the completion of this punching operation, the plate is moved transversely so that another row of filled apertures is underneath the punches. At the same time, the screw feed means has advanced a group of empty shells under the apertures. The filled shells containing the loose priming mixture continue their movement to the left, and as they reach a point under the spinner means at Bil, a shell is moved out of the row and clamped under a spinner H34 of spinner means 60. The screw thread advancing means makes two revolutions for each revolution of the main shaft, so that every other shell is removed at spinner means 60, as will be explained in detail later. The spinners I34 at spinner means 60 and GI are carried on a vertically reciprocating head so that the spinners I34 will enter the clamped shells and cause the loose priming mixture to be forced into final position. The other shell containing the loose priming mixture is carried past spinner means 60 until it reaches a point opposite spinner means 61, whereupon it is removed from the track and the spinner means iii in a similar manner places the priming mixture into permanent position. It is seen, therefore, that as the machine continues in operation, two shells with the loose priming mixture therein will be grouped simultaneously under the spinner means Ell and BI, and the reciprocating spinner head containing spinner means 60 and 6! will be lowered thereon. During succeeding operations, as the shells are removed from the said screw thread advancing means to a position under the spinners, the new shells will push the completed- The shell feeding means 5| will now be described in detail. A hopper or some suitable means is provided at (Figs. 2 and 8A) into which the empty shells are placed. The chain 66 having shell lifting projections El thereon picks up the empty shells from the hopper and carries them upwardly, the shells being held between the wall 61a and the projections 61, the shells sliding off the buckets as the top of wall 61a is reached and falling onto the shell guiding means 69. The guiding means 69 has a slot 15 (Fig. 9) which is the width of the body of the shells but is narrower than the rim so that the rims cannot pass therethrough in the embodiment shown. The section of the track upon which the shells first impinge slopes inwardly and downwardly as shown at H of Fig. 9, and thus assists the entrance of the shells into the slot. This slope gradually changes until it becomes the reverse thereof or outwardly and downwardly sloping with the outer edge sloping downwardly as at 72. In this manner, the excess shells are caused to fall back into the hopper, being guided by the edges of the shell feed hopper 13. To further remove the excess shells that have not entered into the slot, a swinging gate 14 is placed across the track. A rotatin slide through the track because of improper rims, allowing passage of the shell therethrough. The empty shells supported base upwardly continue their downward movement by gravity in the track or shell guiding means 69 until they reach a point 328 (Fig. 2) at the entrance of the inverting wheel TI. The inverting wheel has a series of recesses Iia (Figs. 2 and 8) shaped to receive the body of the shell, the rim of the shell overlying the periphery of the wheel. The charging wheel "I"! is driven by an arm i8 (Fig. 8) which is connected to the cam or eccentric 79 (Fig. 2), said cam causing two complete re ciprocations of arm 18 for each revolution of the main shaft. A spring 32I holds the roller 325 against the cam 19. This cam causes the arm 13 to reciprocate twice for each revolution of the main shaft 80 in the embodiment shown.

Referring now to Fig. 8, the reciprocating action of operating arm 78 is transmitted to wheel '1! by means of the spring 320 pressed pawl 8|, causing the wheel to turn in a counterclockwise direction as viewed in Fig. 8. The indexing or locking pawl 82 is pivoted at 83. As the arm I8 moves to the left, the wheel I1 is prevented from rotating by the friction means 89, wheel 322, spring 323, nut 324 (Fig. 3). The pawl 8|, as the arm I6 moves to the left, slides over a tooth and, after passing same, drops into the next indentation, the friction means just mentioned preventing rotation of the inverting wheel 'I'I. At the same time, a cam 85 contacts roller 86, moving the indexing pawl 62 in a counterclockwise direction and disengaging it from its tooth. Then as the operating lever 18 moves to the right, the wheel 11 is rotated by pawl 8| until the tip 81 of the indexing pawl rides on top of a tooth. At this time, the cam 85 has been removed from under the roller 86, and as the next indentation 81 is reached, drops into the next tooth. Thus it is seen that 8| will continue moving the wheel 'I'I until the tip 81 engages the next tooth and stops the wheel at the correct point. This point is so chosen that a shell receiving recess'IIa is in exact alignment with the slot I in the track 69, allowing an empty shell to enter the recess. The spring 32I and roller 325 allow the cam 19 to continue its rotation after indexing pawl 82 has stopped the rotation of the inverting wheel l1, thus preventing damage to the parts. The wheel continues this type of movement until the shell has been delivered to a point 180 degrees from that in which it was received, at which time it will be inverted or base downward. At this point, it will be directly over a moving belt 38 (Figs. 3, 8 and A thin curved piece 89 (Figs. 8 and 10), passing through an annular concentric slot 96 in the wheel, engages the shell and moves it out of the inverting wheel into the passage-- way 9I (Fig. 10), and onto the moving belt. The passageway 9| is only slightly larger than the shell, thereby preventing the shell from turning over or jamming therein. The empty shell continues in this passageway until it reaches the spring 92, which forces the shell against the screw thread feed means 54. In the event that the shell fails to engage properly, the spring 92 will yield and prevent damage or jamming of the machine at this point. The screw thread feed means 54 positively holds the shell in upright position between the screw feed means and guideway 93. The belt 88 is driven by the main shaft through pulley 94, belt 95, pulley 96 and bevel gears 97. It can thus be seen that'theinverting wheel moves twice for each revolution of the main shaft 80, delivering an empty shell to the belt 88 at each movement, and that the screw feed means makes two revolutions for each revolution of the main shaft 80, so that each of the threads in screw 54 will have an empty shell therein positively held between the thread and guide 93. It is also evident that the ratio of the feed means and screw feed can be changed by proper design of the came to deliver shells at the desired rate to the charging and spinning means.

CHARGING ltlwims The plate charging means will first be described in detail. In this type of charger a flat plate 55 is provided containing transverse and longitudinal rows of apertures 56, as seen in Figs. 3, 6 and 12, the size of these apertures being such that when a pasty priming mixture is rubbed onto the plate and then the excess removed, the apertures will contain the correct amount of priming mixture for each shell. Plate 55 is filled at a point remote from the machine and placed in position on top of the carriage 98, the plate fitting on projections 99 and I09. The carriage at this point is in its extreme forward position so that the first row of apertures will be directly under the punches IIlI. Punches I 0| are carried on a reciprocating means I02 (Figs. 3 and 6), said reciprocating means being operated in a vertical direction by the charger operating arm I03 pivoted at I04. An enlarged head I05 of the arm engages a suitable slot I06 in the reciprocating charger means I02. Charger operating arm I03 is operated by the cam wheel I 01 as seen in Figs. 2 and 6. The cam wheel H5 is connected to cam wheel I01 by means of a tube 252 (Figs. 4 and 12) such that H5 and I91 will rotate together, the main shaft 89 serving as a shaft upon which this assembly rotates. Wheel I0! is driven by shaft by means of gear 253 (Figs. 4 and 11) which is keyed to shaft 80, gear 254 meshing with gear 253', said gear 254 being pivoted at 255 on the main frame, gear 256 integrally connected with gear 254 meshing with the internal gear teeth 251 of cam wheel I91. In the specific embodiment shown, the ratio of this gear train is such that eight revolutions of the main driving shaft cause one revolution of I07 and I I5. These cam wheels and the ratio of their speed to that of the main shaft may be changed as necessary to give the correct relation between the movement of the charger and the shells in the row in the feeding means. An indentation I08 (Fig. 6) is provided on the interior annular surface I09 of charger operating cam I01. This indentation allows the tip I I0 of the charger operating lever I03 to move upwardly abruptly as these parts register. The rapid upward movement of tip H0 causes reciprocating charger means I02 to move downwardly into the apertures 59 of the plate 55 so as to drive the pasty priming mixture contained therein into the empty shells III under said'apertures. Guiding means H2 and H3 serve to position the reciprocating charging means I02. The plate 55 is carried on the movable carriage 98, said carriage being movable inwardly in a correct relationship to bring a filled set of apertures underneath the punches of each movement. The carriage 98 is moved in the manner about to be described. Carriage operating bar H4 is reciprocated by means of carriage operatingcam H5 (Figs. 2 and 6) through roller H6, operating lever HI,

connection I I8, to the carriage operating bar I I4. The lever I I1 is pivoted at I I9 to the main frame, and adjusting means I28 is provided so that the stroke of the reciprocating bar may be varied. The carriage operating cam II5 has an interior track adapted to receive the roller II6 (Fig. 6). Attached to the carriage 98 are racks I2I and I22. The teeth of rack I22 are engaged by the carriage operating pawl I23 and the teeth of rack I22 are adapted to be engaged by the carriage indexing pawl I24, the indexing pawl I24 being pivoted at I25, said pivot being adjustably attached to the base, as at I26 and I26. As the charger carriage is drawn completely to the left 'when a new plate is placed thereon, the pin I21 will strike projection I28 on the operating pawl I23 and move the pawl counter-clockwise, causing the point I29 to pass over the spring I30 and assume the operative position shown in the dotted lines; The purpose of the spring I30 will be set forth presently. As the operating bar H4 is moved to the right by the cam II5 (Fig. 6), the tip I8I of the operating pawl will engage a tooth in the rack I22 and start the movement of the carriage 98 to the right; At this-moment, the pin I32 is effective to hold the indexing pawl I24 out of engagement with its rack I2l because of the raised surface I33 on the indexing pawl. As the operating bar II4 moves further to the right, the indexing pawl will be released and will engage its proper tooth in rack I2I, thereby properly stopping and indexing the carriage 98 so that the next row of apertures of the plate 55 will be directly under the charging punches I8I. As the carriage 98 is moved inwardly and reaches the last row of apertures, the pin I21a engages the projection I28, rotating the operating pawl I23 in a clockwise direction so that it will assume the position shown in full lines and will not engage the teeth of the rack I22 and therefore insure stopping of the carriage at this point. At the tim the carriage 98 reaches this last row of apertures, a suitable stop means also stops the operation of the machine.

On the side of charger carriage 98 is located a cam 24I, best seen in Figs. 11 and 12. The cam 24I engages roller 242 which is connected by shaft 243 to the block 244 carrying roller 245. The block is slidable perpendicularly of the carriage in a suitable guide means 246 and is urged in the direction of the main driving shaft 80 by means of a spring 241. A projection 248 is provided for engagement with a switch operator 249 of switch 250 for the purpose which will be presently set forth. A carriage stopping cam I is placed on the periphery of the charger punch cam wheel I01. The spring 252' holds the block 244 towards the carriage 98 and thereby removes the roller 245 from the path of the cam 25I until the last row of apertures 56 of the charging plate 55 has been reached, at which point the cam 24I contacts roller 242, moving the block 244 away from the carriage so that roller 245 will be contacted by cam 25I, forcing the block 244 against spring 241 and causing projection 248 to contact switch operator 249 to operate switch 250 and stop the machine at the proper point. This causes the machine to automatically stop as the last low of apertures in the charging plate is reached.

The plungers IOI may be mounted on reciprocating plunger means I02 in such a manner that a side play at 334 is provided to insure the registry of the plungers with the apertures in the plate; -Plungers IlII may also be provided Priming spinners After the shells have had the loose priming mixture placed therein by the charger as just described, it is necessary to move the priming mixture into final position in the rim of the shell, assuming that the shell is of the conventional rim fire type. In the embodiment of the machine being described, there are two spinners used, although it is to be understood that one or any number may be used providing the machine is properly indexed and constructed therefor. The spinners I34 (Figs. 3 and 5) are held in the rapidly rotating spindles I35 by any suitable chuck or holding means, the spindles I 35 being .driven by the pulleys I36 through the hollow rotating tubes I31 which are suitably mounted on the hinged spindle holding plate I38. The spindles I35 are so mounted in the rotating tubes I31 that they may have a vertical movement therein, the springs I39 serving to hold the spindles in their downward position relative to the tubes I31. In thisrmanner, an obstruction or unevenness will cause a spindle to move upwardly against the tension of itsv spring I39.-

The spindle holding plate I38 is hinged at 326 so that it may be raised upwardly to facilitate inspection and removal of the spinners, a hook I40 being provided to hold it in the raised position. A reciprocating plate I4I, to which the spindle holding plate I38is hinged, is reciprocated by a lever I42. The plate I4I reciprocates in suitable guides in the frame of the machine as at 3I5 (Fig. 2). The spinner head cam I44 operates to reciprocate the intermediate spinner operating lever I43 by means of the internal cam surface I45 and roller I46. The intermediate spinner lever I43 is pivoted by suitable means at shaft I41 and has an oppositely extending arm I48. The arm I48 operates through the adjusting screw I49 to move spinner reciprocating lever I42, the end I50 of arm I42 entering a suitable aperture I5I in the reciprocating 3 plate I4I so as to reciprocate the spinner head in accordance with the action of spinner cam I44, 2. spring 258 holds lever I48 and I42 in engagement. A quick detaching means of any suitable type may be provided at I52, such that the hinged plate I38 may be readily released and swung to its upward position for the purposes previously set forth. This may take the form of the slidable arm 385 which is locked in place when the plate is in operating position by bolt Arm 385 has a fork end that straddles bolt I52 so that when arm 385 is moved from engagement with I52, bolt I52 will pass through plate I38 as the plate is raised. An electric motor I53 or other suitable driving means is connected by the belt I54 to the pulleys I36 in such a manner that by merely releasing belt I 54 and the fastening means I52, the spinner plate assembly I38 may be swung upward. Spinners I34may be of :any conventional design; one
