Mounted also on the shaft 3 is a ball thrust bearing .5, and the said worm .4 and. bearlng 5- are'further inclosedin a casing 6 mounted on a plate7 to whichis attached adapted to be entered by 'a pin 10 connected to the link 11 mounted on the controlling lever 12 provided with a halidle13. A handle f 14' is also rigid with thecasing' 6, and 15 represents a pivot about which the worm4 porting the catch disk 8 provided with a slot 9 j may turn. 16 represents a bracket for supthe pin 10land one end of the v =4 meshes and the said gear is mounted on "the driving shaft 1'8v carrying the cam 19,
and provided with the bearings 20 and"21..
The said cam 19 contacts with the roller 22 pivotedas at 23 Figs. 1 and 5 to the guide clear from, Figs. 1, 3,5 and 6.- The said plate 24movingin' theguides 25, as will be" guide plate v 24 as best illustrated in Figs. 6
and.7 is provided with an abrupt shoulder 26fagainst,which fit guide plates 25 and is provided with a. vertical edge 27' which fitsagainst a-bearing on the frame 1, so that the reciprocations to be disclosed below of the said guide plate are exceedingly steady. and

' As best Shown in Fig. 7 a check so is rigid with the said guide plate 24 and reciprocates with it. This said chuck is provided with an outer casing 31 provided with a set'screw' 32 adapted to engage an inner tube 33, screw.
collar or head 39 against which takes the enlarged head 37 turn provided with a spring 40, and the said .plungeris alsop'rog I forwardly extending rod The" said second tube.
vided with themember 41 as shown.
threaded at its rear end as shown and prov 36 is also screw threaded at its end opposite the head 37 and receives the third tube 42 provided with the tapered wedge shaped head 43 fitting against an oppositely tapered opening 44 with which the first tube 33 is provided, all as will be clear from Fig. 7.
The said third tube 42 is internally screw threaded at its end opposite the tapered member 43 and receives the reducing screw threaded bushing into which is further screw threaded the combined set screw and nut 46 through which'passes the rod member 41 carried by the plunger member 38 as shown. The said combined set screw and nut 46 takes against a secondplunger member 50 controlled by a spring 51 one end of which takes against the rear end of the said plunger 50 and the other end of which takes against a bushing or feed member 52 adapted to accommodate the bullets as will presently appear. The body 53 of the said'plunger 50 fits the said third bushing 52 and 're- 'ciprocates therein as will be'readily understood. Springs v54 are provided to permit the sleeve 33 to yieldingly slide in the easing 30 should it be fed too far forward.
From what has been so far disclosed itwill now be clear-that power being appliedsible, by the nut 35 and the set screw 32 serves as a key to prevent said tube 33 from rotating during the swaging operation. The
second tube 36 is likewise so adjusted as to cause the tapered end 43 of the thlrd tube 42 to accurately and firmly fit the tapered opening 44 of the tube 43, the pin 120 like wise serves to prevent its rotation. The combined set screw and nut 46 which may be changed for'bullets of different dimensions is then accurately adjusted so as to limit the reciprocations of the second-plunger 50.. The said second plunger 50 is reciprocated by means-of the rod like member 41 of'the plunger 38 striking the enlarged head of the said second plunger 50 in a manner to be disclosed below. The reciprocations of the said second plunger serve to permit bullet blanks to be received in the bushing 52 and causes the finished bullets to be ejected therefrom as will likewise be disclosed below. k
In order that the slide plate 24 may be reciprocated a plurality of springs 55 are provided and one end of said springs are conveniently anchored in the bearings '20 and'21 as-will be clear from Fig. 3 while the other end of said ,springs is conveniently fed to the bushing 52 of the chuck 30, I
provide a hopper and other mechanism now 1 to be described.
Mounted on the power shaft 18 is a cam 60" against which takes a roller 61 mounted i on the arm 62 carried by the shaft 63 oscillating in the bearings 64 and having the dependlng arm 65 taking against the spring controlled plunger 66 mounted in a bracket 67 carried by the main frame 1. mounted onthe oscillating shaft 63 is the arm 68 carrying the feed hopper 69 best shown in Figs. 8 to 12. The said feed hopper is tapered as illustrated, and its lower end is provided with a block 70 secured to the said hopper as by brackets 71 and a plate 72 provided with a curved surface 73 as shown. Associated with the saidblock 70 is a spring pressed plunger 74 provided with a head 7 5 adapted normally to prevent the bullets from being fed out of the hopper 69 but also adapted to be raised against the compression of the spring 76 surrounding said plunger 74 and to permit said bullet blanks to leave said hopper 69.
It will'now be clear that as the cam 60 revolves it will oscillate the arm 62 and thereby oscillate the shaft 63 and hopper carrying arm 68. The oscillation of the arm 68 will move the hopper 69 up and down,
Also
and when in its upper position the spring- 76 will maintain the head 75 over the delivery opening of the said'hopper 69 and thereby prevent the bullets from leaving said hopper; On the other hand when the hopper 69' moves to its lowest position the curved surface 73. of the plate -7 2 will take against the shoulder 78 on the chuck 30 and the flat surface of the plate 72 which extends in a plane at right angles'to'said curved surface 73 will take against the flat surface 79 of the collar or extension 80 on the tube 33 of the said chuck 30, all as is indicated bythe dotted lines in Figs: 8 and 9. The'bullet blanks are forced from the hopper 69 into the chuck 30' by the,
mechanism now to be described.
Pivoted to the frame 1 a aa 85 See g- 12 is pivoted ciprocating bar 91, but the parts are so,
7 the said slot 93 the reciprocations of the jection 89 on the cam 60, and said roller is also connected as by a pin 90 to one end of a reciprocating bar 91 moving in the guides 92 as illustrated. The other end of said bar 91 is provided with a slot 93 see Fig.-
"8 into and out of which moves the lever 94 as the hopper arm 68 rises and falls'as will presently appear. The said lever 94 at one end to the said hopperi arm 68 as at 95, and at its other end 'coiiperates with the pin 97 rigid with the slide 98 movingacross the delivery opening 100 of the hopper 69 as will be clear from Figs. 8 to 12. Accordingly it follows that as the hopper arm.
68 rises and falls the lever 94 will enter and leave the slot 93 in the retimed that when the saidv lever 94 is in bar 91 will move the slide 98 backward and forward across the delivery openings 1 00 ,and thereby force out of the said hopper 1ndividual bullets. The parts are further so timedlthat when the slide 98 is moved in such a direction as to force the bullets into the bushing 52 of the chuck 30, the head 75 of theplunger 74 will be lifted, so as not to obstruct the movement of the said bullets. This is accomplished by the fact that the said-head 75 when the hopper 69 is in 'its lowest position rests upon the shoulder 101 I of the bushing 52 as will be clear from the 1 the projection 110 and roller 111. Secured.
dotted lines in Fig. 9 and the fulllines in Fig. 7. The parts are further so timed that when this feeding action of the bullet blanks into the bushing 52 takes place the whole chuck 30 and its associated parts havebeen retracted by the springs 55 towardthe left-' as seen in 40 Fig. 3. Immediately after this feeding action takes place the hopper and arm 68 are raised in the manner just described and the entire chuckv 30,-as well as. the fed bulletblank is moved toward the right as seen in Fig. 3 by the action of the cam 19 and the projecting end of the said bullet blank entered into the swaging head 125 as will be presently disclosed.
' Attached to the frame 1 -'s a'bracket or y and 7, provided with an extension 106 .to which is pivoted as at 107 the dog 108 having the shoulder 109,
casting 105 see Figs. 2, 5
to the slide plate 24 see Fig. 7., is .the cam surface 112 which moves under the roller 111 as. the said slide plate 24 reciprocates, and therefore said cam surface 112 serves to raise the dog 108 into its full line posi- I tion-shown in Fig.7, while gravity aided by ments just disclosed after theprojection 110 a spring pressed plunger indicat'edat 113, causes said dog 108 to fall to such a position that its shoulder or projection 110 will come opposite, the extreme end 114 of the plunger 38. It results from the moveis moved down behind the extreme end 114 of the'plunger owing to the chuck 30 and the plate 24 having moved toward the right as seen in Fig. 7, that the nextmove-- ment of the plate 24 and chuck 30 toward the left as seen in Fig. 7 will cause the said end 109 to contact with said projection 110 andthe said plunger. 38 together with its said'rod like extension 41 to contact with the plunger50 and cause the body portion 53 thereof to force the finished bullet out of the bushing 52, as will be more fully disthe manner just disclosed, it of course has to move to the right as seen in said figure, and'the bullet blank 115 being held in the bushing 52, the said blankis caused to enter the swaging head 125, whereupon the bullet blank 115 is properly shaped and the bullet thereupon finished. After this finishing leftas seen in Fig. 7 and the finished bullet is discharged'in the manner just stated.
closed below. But, before the chuck 30' moves to the left as seen in Fig. 7, and in,
'operation the chuck 30 then moves to the The swaging head 125 may be of any suitable and well known construction, but
I prefer to employ the well known hammer 130' in order to keep the valve normally closed. In orderto automatically open the valve at the proper time, I provide the hop per arm 68 with a suitable cam 131, see Figs. 11 and 13, which contacts with the said delivery pipe 129 at the proper moment, and thus turns the said pipe against the action of the s ring 130 to' open the valve. When contact 129 is not had, the spring 130 swings "the etween the cam 131 and the pipe pipe 129 to the right as seen in Fig. 13 and '1 out of the way. of the swaging head- On the other hand [when said pipe' is brought into the positionshown in Fig. 13 its ex treme end is in close proximity to the swaging head and the air delivered therefrom blows away any particles of metal or other particles which would interfere with the'ac-.
"curate shaping of the bullet. When bullet blanks are fed out of the hopper 69 into the bushingj52 they are first caught by the blank controlling member 135 carried by the angular shaped to the hopper 68. A rod member 138 pivoted as at 139 to said angular member 136' is controlled by the spring 140 and slides arm136 pivoted as at 137.
through the lug 141, and thus controls the movements of the said arm 136 and the blank controlling member 135. The action of this bullet controlling member 135 is .to
support and hold the bullet blank before and just after entering the bushing 52; and
-as the arm 68 and the hopper 69 rise thatportion of the bullet blank 115 which projects beyond the said bushing 52 snaps past the said controlling member 135, so that the bullet blank then remains free to be .projected into the swinging head 125' In the modified form of my bullet feeding mechanism illustrated in Figs. 15, 16 and 17 on the shaft 18 are mounted the two cams 150 which take against the rollers'151 carried by the slide plate 152 to which is rigidly secured the magazine supporting member 153 carrying the magazine 154 and provided with the bullet delivery opening 125. Also mounted on the shaft 18 isthe third cam 156 taking against a third roller 157 mounted on a' second slide 158 moving 20 I relatively to the plate 152 and carrying the plunger rod 159 surrounded by the spring a 160. The said plate'152, supporting member 153 and magazine 154 are returned against the action of the cams by means of the springs 55 illustrated in Figs. -1, 2, 3 and 5. The second sliding member 158 and rod 159 are returned against the action of the cam 156 for the said rod being rigid with the said member 158, and the said spring 160 taking against the member 153' the said member 158 and rod 159 are forced to the left, and for a distance sufiicient to permit a bullet blank 115 to fall down and' register with the delivery opening. 155. Upon the continued rotation of the cam 156 the said rod 159 is forced forward into the position shown in Fig. 15 and the said bullet blank 115 is fed partially out of the open ing 155, which is provided with a bushing (not shown) in all respects the same as the bushing 52 illustrated in-Fig. 7 The members 152 and 153- are next moved toward.
the right as seen in Fig. 15 until the face of member 153 contacts with the face of the swaging head 125. The said member 153 now remains stationary and the bullet blank 115 being forced into the opening 165 of the .swaging head 125, is suitably shaped. The
' finished bullet is next ejected from the opendistortion of the bullet is prevented.
The operation of my machine may be briefly summarized as'follows: The'hopper 69 having beenfilled with bullet blanks, the
machine may be started by raising the handle 14 and with it casing 6, thus engaging theworm 4 with the worm wheel 17. Power is.
now transmitted from pulley 2 through shaft 3 and worm 4 to worm wheel 17 and cam shaft 18, thus revolving cams 19 and 60. As
- chuck 30.
- cam 60 revolves, roller 61 bears against the cam face and engages the cut away portion of sald cam, as shown in Fig.3. This causes the shaft 63, upon which is mounted the arm i 68 carrying hopper 69 to be moved through an arc of a circle. The action of the spring plunger 66 and lever then moves pressed said sha t in an opposite direction andjthereby completes its oscillations.'- The hopper 69 is thus brought down to its feeding position and returned. In said feeding position the head 75 of the bullet retaining plunger74 engages the shoulder 101 of the bushing 52, thus raising said plunger against the compression of spring 76 clear of the bullet blank feeding opening, while the curved surface 73 of plate 72 engagesthe shoulder 78 ring the projection 89 mounted on said cam into contact with roller 88 'connectedby pin 90 to bar 91 and thus moves said bar to the left as shown in Fig. 3. This movement of bar 91 is transmitted to lever 94 resting in the notch 93 in the end of said bar and to bullet blank ejector '98 carried by said lever 94. Ejector 98 is thus caused to force a bulside of hopper 69 into the bushing :52 of It will beunderstood that the ejector 98 let blank 115 through the opening in the does not feed the bullet blank 115 far enough i to entirely clear the hopper 69 and its ,as-.
sociated parts: vFor the projecting end of said bullet blank continues to rest upon the concave portion of the controlling member 135, which normally supports the blank and prevents it from dropping out of the hopper 69 through, the opening 100. Now, as the cam 60 continues to revolve the projection,
89 on said cam first disengages the roller 88,
while the ejector 98, lever 94 and bar 91 are returned to their original positions by the.
spring. pressed plunger 175, Fig. 12, connected to said lever 94 by the screw97, whereupon the next bullet blank drops down in a position to be fed to the chuck. v As cam 60 continues to revolve, roller 61 will be forced out upon the raised portion of said cam and through arm. 62 and shaft 63-, the'hopper arm 68 and hopper 69 will be raised clear of chuck 30.. As hopper' 69 moves upwardly the projectingnd of the blank 115, which blank is now rigidly held bythe chuck, will snap past the member 135, forcing said member back against the compression of spring 140. As soon as hopper 69 has been raised far enough to clear the blank 115, member 135 will be forced backby said spring and. will prevent the next blank the air pipe the springs 55.
from dropping out of the hopper throughopening 100. I
During the time hopper 69 is in its downward position, cam 131 has contacted with 129, forcing it over against the action-of spring 130 until its lower end is opposite the opening 165 in the swaging head 125; and at the same time rotatingthe valve 128"to its open position as shown in Fig. 13. This permits air to be blown into the said opening the object being to remove any particles of metal which may have been left by a previous swaging operation; As hopper 69 is raised, spring 13.0 mov'es pipe 129 over out of the way and at the same time closes valve 128 shutting off the air supply.
Cam 19 is. so designed and timed that it now forces the slide or guide plate 24 carrying the chuck 3O forward, thus feeding the bullet blank to. the swaging head. As said slide moves forward it carries with it .the'
cam 112 upon which rides the roller 111, carried by the dog 108; As the cam travels forward the roller 111 follows the contour of said cam under the pressure of the spring pressed plunger 113, and causes the dog'108 to drop until its hose 110 is in line with thenlunger 38 of the chuck.
'Whenthe swaging operation is compieted the cam 19 permits the slide 24 to be returned to its initial" position by the action of The chuck. 30 being integral with said slide of course returns with it and as thenose 110 is now in alinement' with the pl'u'nger38, the end 114 of said lunger con- I I tacts with the said nose, there y stopping the movement of said plunger temporarily. Plunger 38 now being stationary, upon further movement of the chuck to the left, as
seen in Fig. 7, plunger.5 0 will next be i brought into contact with the rod like extenupon still further movement of the chuck' in the same direction the finished bullet will v sion 41 of plunger 38,. whereupon the movement of plunger will be arrested, and
be forced from the chuck and will drop down into a suitable receptacle, not shown,"
and the operation repeated. The swaging head 125, may be operated throughany saidstrap 180.
suitable source of power, as for example, the
pulley 176. The feeding mechanism may be stopped eitherby lifting the-handle 13 and lever 12,
or by pullingdown onthe connecting rod .177; in either of which cases the link 11 will withdraw the pin 10 from the notch 9 1 2) and permit the casing 7 and worm 4 to fall bygravity out of engagement with the gear. 17. At the samev time the. brake strap 180 is applied to the brake drum 181" carried the shaft 18, through the link 182 connectedat one end to said lever 12'and to ing means,
may vary the details ofconstruction as well as the arrangement of parts without departing from the spirit of my invention, and therefore I do not wish to be limited to the above disclosure except as may be required by the claims.
