CARTRIDGE-PRIMING MACHINE.

Ndssasos.

To all whom it may concern:

'Be it known that I, FRANKLIN W. OLIN, a citizen of the United States of America, re-

siding in East Alton, in the county of Madi-' son and State of Illinois, have invented certain new and useful Improvements in Cartridge-Priming Machines, of which the following'is a full, clear, and exact description, reference being had to the accompar'iying drawings, forming part of this specification.

My invention relates to a machine for priming or in other words, introducing into the rims of rimfire cartridges the fullninate through the medium of which :the explosive agent placed in the cartridge is exploded.

Figure I is a top or plan view of my machine. through the machine. Fig. III is an enlarged vertical section taken on line IIIIII, Fig. I. Fig. IV is a view partly in elevation and partly in vertical cross section taken on line IVIV, Fig. II and illustrating the lover mechanism by which the punch of the machine is raised and lowered. Fig. V is an enlarged top or plan view of a portion of the turn table, the shell gripping jaws and the mechanism for operating the movable jaw. Fig. VI is an enlarged vertical cross section taken on line VIVI, Fig. I.

1 designates the base of my machine which is surmounted by a pair of standards 2, see Figs. I and II. p

3 is a post seated upon the base and provided at. its upper end with a shoulder 4.

5 is a turn table which has a smooth upper surface and is disposed horizontally and rev-' olubly fitted to the post 3, the hub of said;

table being preferably seated upon the base 1 and being provided with a belt rim 6 that has utility as will hereinafter appear.

7 is a worm wheel fixed to the hub of the turntable and to which power is applied for driving said table. j

8 designates a main drive shaft that is mounted in suitable journal boxes 9 and 10 seated on the base 1 and which is preferably driven by a power shaft 11 geared thereto. c 12 is a supplemental drive shaft that is provided with a worm- 13 which meshes with the worm wheel 7 ,on the hub of the turn table. This supplemental drive shaft is mounted at one. end in a journal box 14 and the other end of the shaft is cooperatively connected to the main drive shaft by a flexible or universal coupling that has associated therewith a fric- Specification of Letters Itatent.

prises a yoke 15 that is fixed to the supplemental shaft, a yoke .16, pivot screws 17 seated in the arms of said yokes and a ball or other suitable connection -member 18, see Fig. VLfin which said pivot ins are seated. The coupling yoke 16 is loose connected to the end of the main drive shaft 8 by a screw or pin '19. The base of the coupling yoke 16 constitutes one member of a friction clutch, the other member of which is in the form of a collar 20 that is splined to ,the' main driven shaft and is held pressed against the rear face of the coupling yoke 16 by a spring 21 that is seated between said clutch collar and a collar 22 loosely mounted on the main drive shaft and resting against the journal box 9 in which said shaft is fitted. The friction clutch construction just described furnishes means whereby the main shaft is caused to drive the supplemental shaft 12 without there being any liability of breakage of any part of themechanism of the machine, due to the turn table 5 being restrained from free rota-.

tion as intended inasmuch as the clutch collar-2O is caused to act upon the-universal coupling yoke 16 with sufficient power to drive the supplemental shalt 12 under normal conditions, whereas, when there is abnormal resistance offered to the rotation of said supplementalshaft, the clutch collar 20 will merely operate idly against theuniversal coupling yoke 23 designates a shelf (see Fig. I) the top of which is flush with the turn table 5 and from which the cartridge shells to .be operated upon in -my machinearedelivered onto the smooth upper surface of said table while it is rotated' I v 24 and 24 are outside guards -of curved shape which occupy lpositions above the per- 1 imeter of the turn ta le but which are spaced apart to permit the performances of certain parts of my machine between them as will hereinafter ap ear. Theseguards are suitably supporte independent of the turn table in order that they will remain stationary while the table is being operated. I

25 is a guide of curved form having its ends secured to a bracket 26 that is supported by the post 3 and rests upon the shoulder 4 of .said post. This guide is so shaped as to cause it to extend from a point distant from the outside guard 24 to a point near said outside guard and then continue throughout the extent of said outside guard 24 and 25 is a guide spaced therefrom throughout the extent of the outside guard 24 approximately parallel with said outside guard. By this arrangement I rovide a channel above the turn table and etween said outside guards and guides which has a tapering mouth for the ready entrance of the cartridge shells into the channel while carried by the turn table and for the formation of the shells into single file after they have reached'the contracted portion of said channel.

27 designates a stationary gripper jaw that is sup orted by the bracket 26 and the rear end which extends into thechannel between the spaced ends of the outside guards and guides and is rovided with a curved pocket 28, see Fi inwhich each shell is\ adapted to seat a ter it has been conveyed to the position occupied by the rear end of the stationary jaw While in an uprightposition and with its open end up ermost.

29 designates a mova i; gripper jaw that is projected into the space between the adjacent ends of the outside guards and guides and located at the rear of the stationary jaw and preferably in alinement therewith. This movable jaw is provided-with a curved ocket 30 that is adapted to receive each shel when it is resting in the pocket of the stationary jaw and the movable jaw is advanced thereto. The movable jaw terminates at its forward end in a stop finger 31 which is adapted to pass be 0nd the side of the stationary jaw that is arthest from the shells as they approach the gripper jaws to be engaged between them.

32 is a slide that carries the movable gripper jaw 29 and, which'is supported by a guide standards2 of the machine.

34 is a cross head fixed to the slide 32 at its rear end. This cross head has connected to it through the medium of pins 35 a pair of retracting springs 36 that are also attached to a cross rod37 mounted in the standards 2.

' 38 is a roller carried by the slide 32..

39 is a cam. fixed to the main drive shaft 8 and having its working face at its forward side. The working face of this cam bears against the roller 38 whereby, during the rotation of themain drive shaft, the slide 32 is intermittently moved in a forward direction by the action of the cam for the urpose of gri ping a shell between the-mova le jaw 29 am the stationary jaw 27 after which, as the cam continues its movement, the slide and j the movable gri per jaw are retracted by the springs 36. uring the period that the 60 cartridgeshells are held between the gripper jaws the fulminate is compressed in the shells through the medium of mechanism that will now be described.

40 designates a unch which enters each- 65 cartridge shell w c it is held between the racket 33 that is in turnsupported by'the' gripper laws 27 and 29, this punch bein referab y pointed at its working end am aving flattened faces as seen at 41, Fig. VI, whereby angles are furnished at the end of the punch. The punch is carried by a spin dle 42 that is rotatably mounted in a vertical position above the turn table 5 in the arms 43 of a slide 44. The slide 44 is loosely fitted in a guide 45 sup orted by the stand ards 2 in order that said slide may be raised and lowered to move the punch 40 vertically 7 above the turn table in order that it may enter into each shell while it is held between the gripper jaws 27 and 29. The spindle 42 is equipped with a belt wheel 46 to which power may be applied in any suitable manner.

47 deslgnates a lever which is pivotally mounted at 48 in a post 49 supportedby the standards 2 and which is connected at its forward end to the slide 44 by a link 50.

51 designates a' cam fixed to the main'drive shaft 8 and having a peripheral working face.

52 is an operating rod reciprocally mounted in a vertical position in a guide 53 supported by the standards of the machine and in the lower end of which is journaled a roller 54 that rides against the working face of the cam 51. The operating rod 52 is provided at its upper end with a yoke 55 through which the lever 47 passes and in the'sides of which are slots 56. The slots in the yoke receive studs 57 projecting from the lever 47 and having connected thereto springs 58 that are alsoconnected to the upper'e'nd of the operating rod 52 by attachment to studs 59 0 projecting therefrom.

For the pur' use of counterb'alancing the slide 44 the spindle and the parts supported by said slide 111- order that said slide and suported members will be normally suspended in elevated positions and moved to such position after they have been lowered, I provide a retracting s ring 60 that is connected 'to the rear arm of t 1e lever 47 at one end and at its opposite end is attached to a fixed part of 1 the machine, for instance, the guide 53, as seen in Fig. II, and also provide a counterweight 61 adjustably mounted on the rear arm of the lever which maybe shifted for the purpose of securing an accurate retractin action upon the lever without sudden shoc or ar, due to an abnormal retracting action.

In the practical use of my machine the cartridge shells are fed onto the turn table 5 in upright positions and with their open ends uppermost and as the turn table revolves it carries the shells through the channel between the outside guard 24 and the guide 25 with the result of causing the shells to be carried one by one into positions between the gripper jaws 27 and 29, due to the actuation of t e last named or movable jaw. Each shell remains in position between the gripper jaws while the punch 40 is lowered thereinto and rotated for the purpose of pressing the 1 fu'lminate into the rim of the shell, an action that is facilitated due to thedescribed contour of the working end of said punch. The

lowering of the punch into the shell is accomas follows:-

As thecam 51 rotated with the main drive shaft 8 it ,acts to im art vertical movement to the operating ro 52 with the result of causing said rod to exert an u ward pull upon the springs 58 that unite sai rod to the lever 47 and as a consequence, the slide and punch spindle are lowered to place the punch inoperative-position. The springs 58 serve in conjunction withthe parts with which they are associated to yieldingly hold the"- punch depressed in order thatit may give if an excess of resistance-is offered to it. Immediately after thefulminate is' pressed into a gripped shell the movable sufiiciently at this time to permit such retraction, The movable aw 1s retracted suf- .,ficientl 'each time to (permit of the shell, which asbe'en operate upon, being carried up on' the turn table from its position at the at the forward en passing intothe course of travel of the shells rear end of the stationary gripper jaw and past the finger 31 at the forward end of the movable aw. The movable jaw-returns immediately to the stationary jaw after said shell has passed it and the next succeeding shell is carried into position between the gripper jaws and i ped thereby, the finger o? the movable jaw again with sufficient promptness to prevent the shell from being carried past it.

By the use of the turn table or revolubly mounted table 5 I provide for a very rapid 'of the post 62 and contaimng a guide-way 68.

feeding of the shells into positions to be operated upon for the forcin of the fulminate into the .rims thereof an therefore. the ma chine herein described is' of a much greater efficiency than are machines commonly employed for performing the operation for which my machine is designed.

For the purpose of preventing the cartridge shellsfrom becoming clogged while passin throu h the channel above the turn tablet at leads to the grip er j aws I provide an agitator that is located alongside of the outside guard 24. This agitator comprises the following parts: 62 is a post, see Fig. III, which is suitably supported at the point named and on which is'mounted a sleeve 63 that is provided with a heltwheel 64 which receives a belt 65 that leads from the belt rim 6 of the turn table 5.- The sleeve63 is also provided with a fluted rim 66;.- 67 is a' head mounted in a stationary position at the top 69 is an agitator bar sli dably fitted in the rated gripper jaw 29 springs 36 conguide-Way68 and one end of which projects 1nto proximity with the channel outside guard 24. The agitator bar is provided at 1ts other end with aleg 70 that occupies a position adjacent to the fluted rim 66 of the sleeve 63 and is held in contact therewith by a s ring 71..

uring the. operation of the machine, the sleeve 63"is rotated and the fluted rim 66 turning in engagement with theagitator bar 69 causes said bar to be intennittently retracted against the action'of; the spring 71 and each time that the bar is moved forwardl by said sprin it strikes again'stthe ,outsi e guard 24 wit the result of jarring" said outslde guard and any shells that may be restin thereagainst so that they will be sepa- Irorh each other they become choked in the channel through which they" are passmg I Claims? 1.
