MACHINE FOR IRIMMING CARTRlDGE-SHELL'S.

SPECIFICATIOFT forming part of Letters Patent N 0. 500,511, dated June 27,1893.

Application filed September 28, 1892. Serial No. 447,156. (No model) To all whom, it may concern.-

Be it known thatl', CHARLES R. RICHARDS, a citizen of the United States, residing at Bridgeport, in the county of Fairtield and State of 5 Connecticut, have invented certain new and useful Improvements in Machines for Trimming Cartridge-Shells; and I do hereby declare the following to be a full,clear, and exact de scription of the'iuventiomsuch as will enable others skilled in the art to which itappertains to make and use the same. I

My invention has for its object to produce an automatic machine for trimming cartridge shells, my novel machine being adapted to manipulate the shells to be operated upon by any ordinary or preferred style of trimming or cutting tool, for example a tool for cutting cfl? the end of a shell and for chamfering out the inner edge thereof as shown in patent to 29 Gilbert and Thomas, No. 476,009, dated May 31, 1892, or a tool for trimming the heads of shells as shown in my former Patent No.

-t79,125, dated July 19,1892, or any of the vari ous other tools for trimming or finishing the z 5 ends or heads of metallic shells.

\Vith these endsin view I have devised the novel machine of which the following description in connection with the accompanying drawings is a specification.

Figure 1 is a rear ele ation of the machine complete; Fig. 2 an end elevation, the guard being in section; Fig. 2 a detail sectional view on the line 1?. n in Figs. 2 and 4; Fig. 3 an elevation on an enlarged scale the position 3 5 of the parts being the same as in Fig. 1 and the reversing disk in section; Fig. eta section corresponding therewith the reversing mechanism being removed, and the section line being indicated by x a: in Figs. 2, 5 and 8; Fig. 5 a section on the line y y in Fig. 3 looking down, the feed slide having just expelled a finished shell; Fig. 6 an enlarged sectional view of the hopper and the operating mechanism therefor, on the line 1211 in Fig. 7 look- 5 ing toward the right; Fig. 7 a section on the linezz in Fig. 6 looking toward the left; Fig. 3 an enlarged detail view corresponding with Fig. 5 except that the feed slide is in the receiving position, the shell just fed forward being clamped in the position in which it is operated upon by the trimming tool, Fig. 8-

a similar view, the feed slide being shown as carrying a shell forward into position to-be operated upon; Fig. 8 a detail sectional view on the line 0" r in Fig. 8; Fig. 9 a section on the line .9 sin Fig. 8; Fig. 1 an enlarged sectional View of the reversing disk and case, the plane of the section being at right angles to the plane of the section in Fig. 3; Fig. ll'an enlarged sectional view on theline r r in Fig. 6a 10, the plane of the section being the same as in Fig. 3; Fig. 12 a detail view of the lower end of the delivery tube, showing the manner in which the shells are delivered to the feeding mechanism, the fingers being in section; Fig. 13 an inverted plan view corresponding with Fig. H illustrating the cam for operating the reversing mechanism; Fig. let an end elevation of the reversing mechanism showing the cam by which the reversing mech- 7o anism is operated, the parts being shown in the locked position; Fig. 15 an elevation as seen from the right in Fig. 14; Fig. 16 a section on the line 20 win Fig. 14; looking toward the left; Fig. 17 an end elevation of the' reversing mechanism corresponding with Fig.

14 except that the parts are shown in the released position, and Fig. 18 is a detail view illustrating mechanism for throwing the pawl which operates the reversing mechanism out of operative position and retaining it there.

1 denotes the bed which is supported by suitable legs 2-and is ordinarilyprovided with a guard 3 around its edge.

All of the different movements of the-ma chine with the exception .of. the rotary movement of the trimming tool are communicated by a shaft 4 which receives motion from a belt, not shown, running over a belt wheel 5, and which carries a belt wheel 6, a bevel gear 7 and a disk 8 having a cam groove 9 in its face by which vertical reciprocatory movement is imparted to the carrier for the trimming tool. Bevel gear 7 meshes with a bevel gear 10 on a vertical shaft 11 which carries a 5 cam 12 by which motion is imparted to the feed slidc,a cam 13 which operates the clamping slide and a face cam 14 which operates the reversing mechanism; Shafts t and 11 are journaled in a heavy casting 3 which is too rigidly secured to the bed, the lower end of shaft 11 turning in a bushing 11, which or:-

tends through and is rigidly secured to the bed, and the upper end turning in a bushing 11 secured in the casting.

In the drawings I have illustrated a construction especially adapted to operate in connection w th a tool for trimming the heads of .shells as for instance the tool described and claimed in my said formrPatent No. 479,125. It will be understood as the description proceeds that in order to place the shells in position to have the heads operated upon, re-

, through which the shells pass, and a sleeve 20 extending entirely through the hopper. portion of the hopper-back of the diaphragm I term the receiving chamber and designate by 21. The bottom of the hopper is inclined as at 22 which causes the shells to feed'thro'ugh opening 19 by-gravity. In front of the diaphragm is a chamber 23 in which is a feed wheel 24 carried by a shaft 25 journaled in sleeve 20. V The feed wheel is provided with a series of arms 26 which extend outward from the periphery thereof and are adapted to enter the open ends of the shells which havev passed through opening 19 into chamber 23. These arms necessarily act to agitate the shells that do not lie in the right position to be picked up, and can of course only pick upv shells which lie'with their open ends toward the arms. v

27 denotes a rim which is secured to the outer face of casting 17. In the inner side of this rim is a groove 28 which is of sufficient size to permit the arms to carry around the shells'which have been picked up. It will be seen in Fig. 7 that the feed wheel rotates from left to right. At the top of chamber the shells that have been picked up by the arms are delivered into a tube 29 the inner face of which isprovided with a slot 30 which permits the arms to pass freely but will not allow the shells to drop out. The backs of the arms are provided with inclines 31 which render it impossible for the shells to. clog in tube 29, but insure that the shells will pass into a vertical tube 32 which abuts against tube 29, said tube 29 being curved to correspond with the curvature of the feed wheel and extending about one fourth around the hopper. which registers with the slot in tube 29 and permits the arms to pass out. It of course follows that when shells have been carried past the top of tube 29 they will drop away from the arms by which they are carried T he Tube 32 is provided with a slot and their forward ends will rest upon the inclines of the arms below them. As the arms pass out through slot the shells drop down into vertical tube 32 and are next operated upon, by the reversing mechanism which 1 shall presently describe. The shells as they fall by gravity from the arms 26 might tip over so as to lie crosswise in the tube which is made slightly larger in diameter than the shells. This action of the shells would tend to clog the tube but by reason of the incline 31 the shell as it falls thereon is caused to slide sidewise and thus rest against the outer wall of the tube wilhonttilting from its proper position. I

Motion is imparted to the feed wheel by means of a crossed belt 34,(Fig. 1) extending from belt wheel 6 on shaft 4 to a belt wheel 35 on a shaft 36 journalcd in a bracket 37 upon the hopper. shaft is a bevel gear 38 Fig. 6 which meshes with a bevel gear 39 on a shaft 40 also journaled in bracket 37.

41 denotes a cone belt pulley on shaft 40, and 42 a belt extending from belt pulley 41 to a reversed cone belt pulley 43 on a shaft 44 which turns on a rod 45, the inner end of which is threaded and passes through a block 46 and engages casting l6. Shaft 44 is provided with a pinion 47 which meshes with a pinion 48 on a stud 49, the inner end of which is threaded and engages casting 16.

5O denotes another pinion turning on stud 49 and made integral with or rigidly secured to pinion 48. Pinion 50 meshes with a pinion 51 on shaft 25 which carries the feed wheel. Shaft 25 is provided with a collar 52, against which a boss 53, on the feed wheel bears, for a purpose presently to be explained. On the outer face of the feed wheel is a hub 54 in which is a socket 55. At the outer end of this hub and rigidly secured thereto are handles 56. At the outer end of shaft 25 and within socket 55 is a collar57. This collar is free to turn on the shaft and is also adapt ed to turn within the socket.

58 is a spring one end of which bears against the base of the socket the other against the inner end of collar 57, thereby forcing boss 53 against the collar and forming a frictional connection between the feed wheel and the shaft. The object of this construction is to permit the operator to hold the feed wheel stationary by-grasping one of the handles should the machine be feeding too fast, but without stopping any portion of the machine except the feed wheel, shaft 25 by which the feed wheel is carried rotating as At the other end of this.

before, and the friction of the spring being arm of the feed wheel, the operator can ordinarily loosen it by oscillating the feed wheel by means of the handles.

59, see Fig, 6, denotes an opening in the to the feeding mechanism with thehead ends downward they will be fed into position to be operated upon by the trimming tool with the head ends up. denotes the reversingdisk lying within a case 61 and keyed toashaft (32 journaled in a sleeve 63 which is rigidly secured to the standard, the case being rigidly secured to the sleeve as shown in Fig. 11. The reversing disk is provided with sockets (it of suitable size to receive the shells,each

socket being preferably provided with a slot which permits the operator to see the shells in the sockets at all times. The outer face of the reversing disk is provided with a hub 54 within which is a socket 55. At the outer end of the hub are secured handles 56. At the outer end of the shaft is a collar 57 loose on the shaft and adapted to turn within the socket, said collar being held in position by nuts 57". A coil spring 58 bears against the base of the socket and against the collar. This spring acts to hold thereversing disk in position in the case against a shoulder (32 on V shaft 62 but permits it to yield outward should clogging of the shells take place, as will presently be morefully explained. The disk being keyed to shaft (32, must necessarily turn with it, but is free to slide longitudinally thereon against the power of the spring. Vertical tube 32 has a lip 32 and is connected to the upper part of case 61 by a spring catch 32 engaging said lip and a delivery tube 66 connects with the lower side of the case as clearly shown in Fig. 2. The shells pass down tube 32 and as soon as. one of the sockets G4 in the reversing disk comes in line with the tube the lowest shell will. drop into the socket the head end being downward. When the reversing disk has madeahalf revolution the socket just referred to will register with tube 66 and the shell will pass out of the socket by gravity and down into the tube, the

shell having beencaused to change ends by the reversing disk and passing into tube 66 with the head end up.

Motion is imparted to shaft 62 carrying the reversing disk in the manner which I will now describe. Turning to Figs. 14 to 18, at the opposite end of shaft'62 from that carrying the reversing diskis an arm 67having a hub 68 adapted to turn on the shaft, said hub being held in position by a nut 69. Just within the. hub and also pivoted on the shaft and adapted to be turned thereon isa lever 7 O the purpose of which will presently be explained. Just within the lever is a feed ratchet 71 keyed to the shaft, and just .within the feed ratchet and keyed to a collar 72 is a stop ratchet 73. 74 denotes the feed pawl pivoted to arm 67, and 75 a spring acting to hold said pawl in engagement with feed ratchet 71. 76 denotes the feed operating rod at the upper end of which is ahead 77 which is pivoted to arm 67 at the opposite end from the pivotal point of the feed pawl, by means of a pin 78 which passes through the head. and the inner end of which is threaded to engage arm 67. This pin extends outward some distance from the head as clearly shown in Fig. 15, in order to provide a point of attachment for a strong spring 79 the purpose of which will presently in a stud S1 rigidly secured to the under side of the bed, see Figs. 13 and 14. At the opposite end of lever 80 is a roller82 which engages face cam 14 at the lower end of shaft 11. The shape of this cam and the movement it imparts to lever 80and rod 76 will be clearly understood from Figs. 3, 4 and 14. It will furthermore be clearly understood from Fig. ll that each upward movement of the rod will causearm 67 to oscillate on shaft (12 and will cause the feed pawl to be carried backward over the face of ratchet 71 sufficient distance to cause said pawl to engage another tooth. It will furthermore be seen from the shape of 'the incline of cam 14 that the upwardand downward movements of the rod are both made quickly so that as soon as the downward movement of the rod commences, arm 67 is free to be acted upon by spring 79 the lower end of which is connected to an car 83 on the bed. This spring is strongenough to draw arm 67 downward again, oscillating it on the shaft thereby causing a forward movement of the feed ratchet by, means of 'the pawl and, consequently of shaft 62 and the reversing disk. It will thus be seen that the movement which places the feed pawl in the position to operate is positive, but

the operation of the feed pawl is produced at any time to stop the passage'bf shells to.

the feeding mechanism or should shells become clogged in the reversing mechanism I have provided a stop motion for the reversing mechanism which I will now describe. 70 which has already been described as adaptref,

Lever I ed tobe turned on shaft 62, is prvided with an incline 84 which is adapted to engage a pin 85 extending outward from the feed pawl, see Fig. 18 whereby the feed pawl is lifted entirely out'of engagement with the feed ratchet. The handle end of this lever is provided with a curved'slot 86 through which a pin 87 passes, the inner end .ofsaid pin being threaded and engaging arm 67. 88 is a'coil spring surrounding pin 87 the ends of which'bear against an enlargement 89 on pin 87 and against lever 70, washers being interposed between the enlargement and the lever. The action of this spring is to hold the lever by friction in any position in which it may be placed, that is to say to retain said lever in its normal position as shown in Figs. 14, 15, 1G and 17, or to retain it in a locking position as in Fig. 18, said lever oscillating with the shaftin either position in which it may be placed until it is shifted by hand to the other position and then remaining in that position oscillating with the shaft until it is shifted back again. It will be seen that when the lever is in the position illustrated in Fig. 18 arm 67 will oscillate as usual but the feed pawl will not come in con tact with the feed ratchet. Pin 85 will simply ride up and down on incline 84 holding the pawl out of contact with the ratchet.

Should the shells become clogged in the reversing mechanism they may ordinarily be loosened so as to drop out into tube 66 by a quick oscillation of the reversing disk by means of the handles or by moving the disk in or out in the case against the power of spring 58, it being understood of course that the shaft oscillates with the disk, but that the disk may be moved longitudinally thereon against the power of the spring. It should i to an arm 92 provided with a sleeve 93 which girthermore be understood that accidents of this class rarely happen with this machine, but I have so constructed. it as to prevent injury thereto under any circumstances, and to provide for the convenient removal of defective shells at any time. Pin 87 extends outward from enlargement 89 and carries a roller 90 see Fig. 15, which is adapted to engage locking pawl 91 and lift it each time arm 67 moves upward. The locking pawl is pivoted is rigidly secured to sleeve 63, see Fig. 16. 94 denotes a tooth on the locking pawl which is adapted to engage either of the notches in the locking ratchet. A spring-95 acts to hold the locking pawl in contact with the ratchet until it is raised, and aguard 96 acts to prevent the locking pawl from being under any circumstances thrown backward out of operative position. The object of this locking pawl and ratchet is to insure that at each forward movement of the feed ratchet, shaft 62 and the reversing disk, said parts shall be stopped at the exact position required to place one of the sockets in the reversing disk in, position to receive a shell from tube 32. It will be seen thatthe upward movement of arm 67 in addition to moving the feed pawl backward from the face of the ratchet lifts The locking pawl is provided with a handle 07 by which said locking pawl may be conveniently lifted out of engagement with the locking ratchet by hand.

Turning now to Figs. 4, 5, 8, 9 and 12 I will describe the feeding and clamping mechanism,2'. c. the mechanism which receives the shells from the delivery tube and carries them into position and holds them while being op.- erated upon by the trimming tool. All of these parts are carried by a block 08 Fig. 4 which is rigidly secured to the bed. The lower end of the delivery tube extends into and is rigidly secured to aholder 90 at the end of a plate 100 lying at right angles to and secured to a plate 101 which isitself adjustably secured to block 08. Plate 101 Fig. 5 is adjusted by means of a screw 102 which engages the rear end of the plate and is provided with a double head 103 engaging a yoke 104 extending upward from block 98, from which view it will be apparentthat rotation of screw 102 will move plate 101 in or out as may be required. The plate is locked in position affor adjustment by means of a bolt 105 which passes through a slot in said plate. and with it holder 90 are adjusted by means of a screw 106 which engages plate 101 and is provided with a rigid collar 107 engaging plate 100, see Fig. 12. It will be apparent from this figure that rotation of screw 106 will move plate 100in either direction as may be required transverselyto plate 101. Plate 100 is locked in position after adjustment by means of a bolt 108 passing through a slot in plate 100 and engaging plate 101. justments enable me to insure that the shells ,shall pass with absolute certainty and uniformity to the feeding mechanism which I shall presently describe, and also require to be changed when the size of the shells being operated upon is changed. As the shells pass out from the holderfsee Figs. 8 and 12 they drop into a recess 109 Fig.8 one side of which is formed in a wearing plate 110 the other side of said recess being formed inupper and lower fingers 111 and 112 Fig. 12 which are pivoted to a feed slide 113 which moves upon the top of block 98. The feed slide is held in position by means of adjustable plates 114 and 115, Fig. 8. Plate 114 is provided with a flange 116 cut away at 1'17 so as not to interfere with the trimming tool, see Fig.9, and to which wearing plate 110 Fig. 8", is attached, this wearing plate acting as one of the side guides for the feed slide and being provided with a recess 109 which forms a portion of shell receiving rccess 109 and with another recess 119 which acts in connection with the clamping slide presently to be described to hold the shell while being acted upon by the trimming tool. When the size of shells tobe operated upon is changed wearing plate 110 is removed and another one attached in its place. Slide 114 and the wearing plate are adjusted by means Plate 100 v v These adof a screw 120 Fig. 4 which engages block 98 cured thereto which engages the under side of plate 114so as to move said plate in or out when the screw is turned. After adjustment plate 114 is locked inposition by means of a belt 122 which passes through a slot in said plate, see Figs. 3, 5 and 8.

123, see Figs. 3, 5, S and 9, denotes an air tube which is connected with a suitable blower, not shown. The position of the end of this tube is indicated by dotted lines in Figs. 5 and 8. It is provided in order to blow away the chips of metal made by the trimning tool. I have shown the air tube as held in place by means of a metallic strap 124 which is secured to plate 114. Plate 115 which forms the other side bearing for the feed slide is simply set up in position by hand and locked there by a screw 125 passing through a slot in said plate. Feed slide 113 is provided with a recess 126 in which is a plate 127 pivoted upon a stud 128. Fingers 111 and 112 are secured to plate 127 by means of screws 129 and 130.

The exact shape of these fingers is of course not of the essence of myinvention. A form in which I have constructed and used them will be'clearly understood from .Figs. 8, 8 and 9. Back of the operative portion of the lower finger, denoted after adjustment.

by 112, and in front of plate 127 is a block 131 formed integral with the rest of said fingers upon which the upper finger 111 rests. Between the fingers is a space 132 the purpose of which will presently be explained, in

connection with the clamping finger; 133 is a coil spring surrounding stud 128, the upper end of said spring bearing against a pin 134 in said stud and the lower end extending outward and being coiled around screw 130, the action of said spring being to force plate 127 against the back of recess 126, see dotted line Fig. 8, and to hold the fingers in operative position as in-Figs. 5 and 8. The shape of the recess in the feed slide in which plate 127 lies will be clearly understood from Fig. 8. Reciprocatory motion is imparted to the feed slide by means of a bell crank lever 135 pivoted on a stud 136 extending through a sleeve 136 on the under side of the lever, see Figs.

which bears against cam 12.0n shaft 11, said cam being formed integral with or rigidly secured to a collar 140 on shaft 11. 141 denotes a strong spring one end of which isconnected to the bell crank lever and the other to an arm 142 extending upward from the bed. The action of this spring is to hold roller 1'39 closely-in contact with cam 12. 143 denotes a set screw in a hub 144 which is-rigidly secured to casting 32sec .Fig. 5. 145 is a lock nut by which the set screw is held in place I The action of this set screw is tocheck the inward movement of is connected rests upon flange 116 and that' the opposite side of the holder is provided with a lip 146 which renders itimpossible for the shells to get out and insures that they drop down into recess 109 as they pass from the delivery tube and holder. At the instant a shell is received in recess 109 the forward movement of the feed slide commences. For convenience in description I will term the recesses in the upper and lower fingers which assist recess 109 in wearing plate 110 to form shell receiving recess 109, as 109 the recesses in the two fingers being identical in shape. The shape of recess 109 is clearly shown in Fig. 8, said recess being preferably made pear shape as shown in said figure, that is to say the forward end of the recess is extended outward forming inclines 109 in wearing plate 110, and 109, in the fingers so as to permit the shell to be forced out of recess 109 and along incline 109, when the feed slide moves forward as clearly shown in Fig. 8, in which the shell is shown as being held in the recesses formed in the-fingers and which I have designated as 109 and between the fingers and the wearing plate, the plate 127 and the fingers yielding outward as shown against the power of spring 133, and the rear ends of recesses 109 holding the shell and acting to force it forward. The feed slide continues to move forward the shell being held as in Fig. 8 until it reaches recess 119 in the wearing plate into which it is forced by spring 133 acting upon plate 127 which carries the fingers. At this instant the forward movement of the feed slide ceases. The fingers will now be in the position shown in Fig. 5. At thisinstant the shell is clamped by the clamping finger acting in connection with recess 119 as will presently be more fully explained. At the forward end of the fingers are concave curves 147 which as the feed slide moves forwardin the position shown in. Fig. 8 engage the shell that has last been acted upon by the trimming tooland expel it from the machine, a trough 148 being provided into which the trimmed shells are forced by the fingers.

149 denotes the clamping slide the construction and operation of which will be clearly understood from Figs-3, 4, 5, 8 and 8". This slide reciprocates in a dovetail groove 150 in block 98' in a line at right angles to the feed slide, see dotted lines Fig. 8. Gibs 149 are provided on both sides of the slide to take up wear from long continued use, -ne of said gibs being adjusted by screws 149?, and the other by screws 149, having at their inner ends collars 149 which engage angle slides 149, see Fig. 8", said screws being locked in position after adjustment by set nuts 119". 151 is abloel( adj ustably secured to slide 119 by means of a bolt 152 which passes through a slot 153 in said block. 151 denotes a clamping finger which is secured to block 151 by a bolt 155. The forward end of this finger is made thin enough so as to permit it to pass readily between fingers 111 and 112 on the feed slide as is shown in Figs. 3 and t. At the forward end of the clamping finger is a recess 156 which receives the shell and acts in connection with recess 1.19 in wearing plate 110 to clamp and hold the shell firmly while it is being acted upon by the trimming tool,sec Fig. 8.

In describing the operation of the feed slide it has already been explained'that fingers 1 11 and 112 carry each shell forward-until recesses 101)" in whichftheshell lies register with re-. cess 119 in the wearing plate into which the shell is forced by the spring which controls the fingers. At the instant that the parts are in this position the clamping slide moves forward at right angles to the feed slide, clamping finger 15 1 passing between fingers 111 and 112 and acting to clamp the shell firmly in the position to which it is carried by the fccd'slide. The trimming tool, the operation of which I shall presently describe .then descends and acts upon the shell. Simultaneously with the clamping of the shclland the commencement of the action of the trimming tool the back ward movement of the feed slide commences. The shell being held firmly by the clamping finger it follows'that fingers 111 and 112 on the feed slide must be forced upward against the powerof spring 133 in order to disengage said fingers from the shell. The fingersyield outward at the commencement of the backward movement of the feed slide in the same manner that they are held outward during the forward movement of the feed slide as shown in Fig. 8. This action of fingers 111 and 112 being so apparent-it is not deemed to require special illustration.

It will be clearly understood from what; has been said that when-the backward movement of the feed slide commences inclines 109" which constitute the forward ends of the shell holding recesses in the fingers will ride over the surface of the shell throwing the fingers outward until the shell has been passed, spring 1 acting upon plate 127 to which the fingers are attached will then force said plate and the fingers back to their normal position as in Fig. 8'. Block 151 on the clamping slide and the clamping finger are adjusted relatively to the slide and necessarily to the wearing plate also by means of a screw 157 which engages block 151 and is provided with a double head en gaginga yoke 158 on the clam ping slide, see Fig. 5. After adjustment the block is locked to the clamping slide by tightening up bolt 152.

Reciprocatory motion is imparted to the clamping slide in the manner which I will now describe. At the inner end of this slide is a loop 15!) which incloses shaft 11 and is provided with a boss 160, on the under side of which is pi oted a roller 161, which bears upon cam 13 on shaft 11, the shape of said cam being clearly shown by dotted lines in Figs. 5 and 173. 162 denotes a lever pivoted on a. stud 1633, extending upward from thebase of casting S. 16& denotes a spring one end of which is connected to one end of the lever, the other to an arm 165 extending upward from the bed. The inner end of lever 162 bears against a shoulder 166 on the clamping slide and by means of the spring acts to force the clamping slide forward and to hold roller 161 constantly in engagement with cam 13 except while a shell is being clamped, see Fig. 8 in connection with Figs. 4 and 5. It will be seen from Figs. 4 and 5 that the rotation of shaft 11 and cam 13 must necessarily impart reciprocatory movement to the clamping slide, the parts being so timed that the clamping slide will move forward and clamp a shell at the exactinstant that the feed slide has placed it in position o be operated upon by the trimming tool. 1

The operative position of the trimming tool is clearly shown in Figs. 3, 4, and E), which see in connection with Figs. 1 and 2. 167 denotes the trimming tool which is carried by a taper spindle 16S journaled in a carrier 169 adjustably secured to a slide 170. The upper end of the spindle is cone shaped and engages an adjusting screw 171 in the carrier, said screw being locked in position after adjustment by set nuts 172. Power is applied to drive the spindle and trimming tool by means of a belt 173 running overa belt pulley 174. secured to the spindle by a set screw 174 and over a pulley 175 on a shaft 176 journalcd in a bracket-177 extending outward'from the bed, see Figs. 1 and 2. 178 denotes a platform secured to the bracket and adapted to carry a basket'or b0x-to receive the shellsas' they drop from trough 148. The outer end of the bracket is bifurcated, as shown in Fig. 1, each arm thereof being provided with-an opening 179 to receive one of the bearings 180 for shaft 176. These bearings are adjustable in the openings by means of set screws 181 which pass through the arms and engage the bearings. 182 denotesoil cups under the bearings. Power is applied to drive the shaft and spindle by means of' a belt, not shown, running over a belt pulley 183 on shaft 176. The belt running over pulley 183 extends to any suitable main or counter shaft, not shown, this being the only movement of the machine that is not driven from shaft at. 181 is aheaded taper bushing in carrier 169 through which the spindle passes and which supports the spindle and" parts carried thereby, the adjustment to compensate for wear in use being effected by loosening set screw 174, setting up the spindle in the bushing and then tightening up set screw 174.".and adjusting screw 171. The outer face of slide 170 consists of a dove tail 191 which engages waysin Fig. 2

the carrier, gibs 185 and set screws 186, see being provided on both sides to take up wear from long continued use. The carrier is adjustably connected to the slide by means of a lug 187 which extends inward from the carrier and lies in a groove 188 in the slide. This lug is threaded to receive a screw 189 having at its upper end a collar 189, and a rod 189 which extends upward ,ing against the collar and the base of the through a lug 190 on the outer face. of the slide and is provided with a head 197, see Fig. 4. It will be seen that rotation of this screw will necessarily move the carrier, spindle and trimming tool upwardor downward as may be required relatively to the slide, head 197 being provided with holes to receive a turning rod so as to give the finest possible adjustment to the carrier and trimming tool. 190 denotes a socket in lug 190 in which is a a spring 190 surrounding .the rod and bearsocket. Theobject of this construction is to provide a yielding upward movement for the carrier, trimming tool, &,c., should a shell slightly longer than the others be presented to the trimming tool, so that no injury can possibly happen to the tool or to the machine. The inner face of slide 170 consists of a dove tail 192 which engages ways in a plate 193 which is secured to casting 3 by means of screws 194. Gibs 195 and set screws 196 are provided on both sides of the slide by which the wear may be taken up after long continued use so as to insure that the slide shall always run trueto the minutest fraction of an inch. Reciprocatory motion is imparted to'the slide by'means of aroller 198 on astud 199 which extends inward from the slide, the roller engaging cam groove 9 in disk 8. The shape of said groove is clearly shown in Fig. 2. The disk is secured to shaft 4 by means of a key 200. It will be seen therefore that the vertical movement of the slide, carrier and trimming tool as well as all the other movements of the machine except the rotary movement of the trimming tool are received from shaft4. The movement of the slide, carrier andtrimmin'g tool is so timed relatively to the other parts The operations of the several mechanisms have been so fully explained in the general description of the machinethat further description of the operation is hardly-deemed necessary. It is deemed sufiicient'for the purpose of this specification to. say that the shells to be operated upon are placed loosely in a hopper in which they are picked up by a feed wheel and delivered into a tube, the feed wheel being provided with arms which enter the open ends of the shells so that it is a feed slide.

impossible for a shell to be delivered to the tube except with the open end upward. In case the machine is required to trim the open end of a shell no reversing mechanism is required as the open ends of the shells will be upward when they pass from the tube. In case it is required to trim the heads of shells they are caused to pass into sockets in a reversing disk which at the end of a half revolution delivers the shell to another tube with the head end up. The shells pass from this tube into a recess formed partiallyin 'a'wearing plate and partially in lingers carried by hen the slide moves forward the shell is carried into a position directly under the trimming tool. At this instant a clamping slide moves forward at right angles with the feed slide and clamps and holds the shell in position to be operated upon. The instant the shell is clamped the trimming tool descends and trims the head, the feed slide and fingers having in the. meantime moved backward, received another shell and commenced to move it forward. The instant the trimming operation is completed the clamping slide moves backward out of the way releasing the shell that has just been operated upon. The fingers upon the feed slide nowmove forward and expel the trimmed shell from the machine and place another shell in position to be grasped by the clamping'slide and operated upon, theseoperations being constantly repeated and the special mechanisms by which they are performed having been fully explained in the general from the principles thereof.
