The table portion 6 is provided therethrough with a vertical hole or opening h and a counter bore h on the upper surface to receive the shell retaining member 32 therein, lthe latter being held in place by set screw 33. The retaining member 32 includes an upraised semicircular lip 34 which is adapted to engage in the annular groove, defined by the ejector rim 35, in the base or back portion of the shell or cartridge casing S and serves to hold the same in place as indicated most clearly in Fig. 3. The retaining member is also provided with a vertical bore 32 therethrough which, when the shell casing S is held by the retaining member, is in vertical alignment with the primer cap aperture p in the back Wall of the shell casing S. Thus, the retaining member '32 presentsa vertical bore through the table portion 6 and this bore conforms in diameter substantially to the diameter of the-primer cap aperture p in the shell casing.
Die member D receives in its internally threaded upper bore portion a a combined ejector and sizing member 59 and including an upper threaded body portion 6@ engageable within the bore portion a and terminating at its upper end in the finger knob n. Depending from the threaded body portion 60 is an elongate stem portion r having adjacent its free Vend an enlarged sizing portici-n64 and terminating at its. free end in a reduced diameter nipple 61 which is adapted to be projected through the primer cap tiring aperture, as shown, and punch out the spent primer cap 39a from the spent cartridge shell casing. The punched out spent primer cap will, of course, fall downwardly through vthe aperture 32 in the retaining member 32. Associated with the threaded body portion 60 of the ejector means is a stop collar or lock nut vmember S8 having a set screw, not shown, preferably associated therewith to retain the proper adjustment of the ejector means, as will be described.
The lowermost position of the carriage 9, and consequently the lowermost position of the die means D, is shown in Fig` 3 and in this position the die means is adjusted vertically by threading the same within the ear portion 11 to achieve the proper height. At this point, the stop collar or lock nut 58 is threaded tightly against the ear 11 and held in place by its associated set screw 58. In this same position, the ejector means must be so positioned as to completely'remove the spent primer cap 39a from the primer cap aperture or pocket pin the shell casing S. For this purpose,the ejector means is adjusted vertically within the die body D so as to attain the proper height and, at this point, the associated stop nut 58"l is locked in place to retain the vproper adjustment. The uppermost yposition of the carriageinember is shown in Fig. 1 and it is'noted in this respectfthat the ysame is held normally in this position by cooperation between the detent member 69 and the pocket 70 in the side of the carriagemember, as is shown. The lowermost position of the carriage member is normally retained by virtue of the engagement of the detent member 69 in the indentation or pocket 71.
Rotatably supported in the bearing portions 20 of frame members 1 and 2 (Figs. 2 and 7) adjacent the upper end portions thereof is a transverse, horizontal shaft member 18 which has pinned thereto, as by the pin member 19, a crank 16 having its forward free end portion pivotally secured, as bythe pivot pin 17, to a pair of depending link members 13 straddling the same and which straddle at their opposite ends and are pivotally secured, by means of pivot pin 14, to an ear portion 15 formed at the upper end of the carriage base 10. Thus, when the shaft 18 is rotated in opposite directions, the carriage 9 will slide vertically up and down in its guideways 12, as previously described.
Atleast one end portion 0f the shaft 18 projects outwardly from a side of the frame F and a handle means 24 is associated therewith which may take the form as specifically shown in the drawings wherein the handle means consists of a bar projecting transversely through the free end portion of the shaft 18 and rigidly secured thereto as by set screw member 25. To prevent longitudinal movement of the shaft 18, an annular groove 23 is formed therein and into which the stem portion of a set screw member 21 carried by the frame F may be projected, as will be most clearly seen in Fig. 7. As the handle 24 is rotated downwardly in the direction of the arrow, Fig. 2, the carriage 9 will be moved vertically downwardly from its position as shown to the lowermost position, as shown in Fig. 3. As the die member moves downwardly to receive the lshell or cartridge casing S, the neck portion 66 of the shell will be reduced in diameter by the bore portion 62 of the die member while simultaneously therewith the nipple 61 of the ejector means will punch out the spent primer cap 39a. When the die member is again withdrawn by moving the carriage 9 vertically upwardly, the resizing portion 64 of the ejector'mean's Iwill pass upwardly through the then necked down portion 66 of the shell casing S and will re-expand the same to conform to the proper diameter for inserting a 'new bullet thereinto. Thus, upon one complete up and down motion of the carriage, the shell casing is ridded of its spent primer cap, while at the Sametime the neck 66 thereof is resized so as to subsequently received a new bullet therein.
The previously mentioned guide portion 7 below the table portion 6 is provided with a vertical bore therethrough which is in alignment with the bore 32 in the retaining means 32 and reciprocable within this guide bore is areload plunger 8 terminating at its upper end in a reduced diameter stem portion 8 presenting at its upper free end a concave depression to receive a new primer cap therein. The lower end of the reload plunger 8 is threaded, as shown most clearly in Figs. 2 and 8, and a stop collar 36 is adjustably located thereon and maintained in proper place by means of a set screw 36', the purpose of the stop collar being to engage the undersurface of the guide portion 7 to limit the upward travel of the reload plunger so that in its uppermost position it will be effective to properly insert a new primer cap into ythe primer cap aperture p in the shell casing or cartridge casing'S. The guide portion`7 is provided with a depending'bifurcated leg portion 27 Vwhich straddles one end of a'lever member 26 and is pivotally secured thereto by means of a pin 28 extending throughboth members. The le'g27-is provided with-horizontal slots 28 in its bifurcated portions within 'whichthe pivot pin 28 rides. The lower end of the reload plunger 8 is bifurcated, as is illustrated most clearly in Fig. 8, andthe same straddles'an intermediate portion "of -the rlever v26 and is pinned thereto as by means of the pivot 'pin 37. The opposite free end of the lever As pinned as by the member 30to a clevis at the lower end of operating rod 2 9 which extends `forms a common operating means for the carriage and for the reloadplunger Snfor performing sequentialreloading operations in a manner to be described presently.
A transfer plate 41 is pivotally secured to the undersurface of the table portion 6 in face-to-facecontact therewith, such connection Abeing effected by means of a pivot bolt 43. The transfer plate includes a projecting ear portion 41', bestshown in Fig. 5, and secured inspaced relation on the undersurface of the table portion 6in dependingrelation thereto area pair of stop pin members 55 and 56 which xthe extremities of the pivotal path of movement of theV transfer plate. Projectingthrough a vertical bore in the table portion `6 is the reduced lower end portion 38', Fig. 6, of a magazine38 `andwhich` includes a vertical sight slot 40 to `determine whether or not there is a supply `of primera caps 39 therein.Y The new primer caps 39 whichare disposed within the magazine 3S are stackedfthereinandwill normally tend to fall by y gravity through the lower end thereof. i, n
The transfer plate 41issubstantially equal in` thickness to that of the individual primer caps 39 and said plate has an `opening 45 therethrough which is normally closedv at its bottom by an end portion 47 of a shutter or retainer 46, `whereby the opening 45 will nest the caps 39 one .at a time. When the transfer plate 41 is in the full line position .as shown in Fig. 5, the opening 45 therein, see particularly Fig.-`6 will`be in alignment beneath the lower end of the magazine 38 and thelowerm'ost primer cap 39 will be disposed within such aperture 45 and will be retained in place therein by `means lof the end 47 of `the shutter or retainer 46 which is pivotally secured to the transfer plate by means of the pivot 48. The transfer k plate carrieea stop pin 50 and a `spring 49 connected between postson the retainer strip 46 and the transfer plate "normally lurges, the retainerfsitripto a position with its i end 47 underlyingthe apertureAS in the transferplate so as `to form .al pockettherewith for receiving the lower-A most primer` capin thestack` disposed Within the maga- '1`he upper`portionl of 4the stein 8' of thereload plunger 8, when `th'ereload plunger is `inits lowermost position, as shown inFigs. 3 and 13, is inthe path of movement of the retainer end47 when theutransfer plateis `swung to its reload position shown `in dotted line4 in Fig. l5,; Thus,
when thetransfer platee-sswung toits dotted lineposition shown inFig. 5the `stem `8 of thereload plunger i will cause the `retainer end 47 to `swing aside and uncover the underside of the aperture "lS'through` the' transfer plate and will deposit the primer rcap in the depression in the upper'end 8',;of theireload-,plunger stem.

ture p in the shell S. Of course, at this time, the spent primer cap 39a is still in the shell casing S. With the parts in this position, the operating handle 24 is rotated downwardly to lower the carriage and cause the die D and its associated ejector means to move toward the shell casing S. At the same time, due to its weight, the reload plunger 8 will be lowered also, withdrawing the reload plunger stem S' from the vertical bore 32 in the retainer member32 so as to permit the spent primer cap to fall downwardly through the bore 32. As the carriage is moved to its lowermost position, the die performs the necking downoperation on the neck 66 of the shell casing while, at the same time, the nipple 61 of the ejector means With the parts still in the lowermost position, the transfer plate 41 is manipulated by swinging its lever 44 in the direction of the arrow, Fig. 9, so that a new primer cap is transferred from the magazine 38 to a position resting upon the upper end of the stem 8 of the reload plunger. The common operating means is then moved in the opposite direction to raise the carriage 9 and elevate the reload plunger S so that the new primer cap is pressed into the shell casing S. At this point, the shell casing is removed and is ready for lling with powder.
A modied form of primer cap transfer mechanism is illustrated in Figs. 9 and l0 and it will be seen that in this modification the table portion 6 is provided on its undersurface with a T slot slidably receiving the transfer n plate 141. The body 142 of the transfer plate carries a retainer strip 146 similar to that previously described and having associated therewith a spring means 149 to normally urge the same into closing relation with a vertical opening 145 through the n'ansfer plate. A stop pin i 150 is carried by the retainer plate 141 so that the spring 149 normally urges the retainer strip 146 to the proper underlying position to bore 145.'
One .corner of the transfer plate is provided with an :offset ear `portion 1,45 underlying an adjacent portion of the table 6 and engageable with a pair of stop pins 146' and 147..to limit the two extremities of travel of the `transfer plate 141. In these two positions of the plate,
the` transfer plate opening 145 is respectively aligned with the lower end of the magazine 38 and the lower end of the bore 32' through the retainer means 32. As is the case in the previously described mechanism, the .reload plunger stern4 8 is in the path of movement of the retaining strip 146 `so that the stem moves the retainer aside when the transfer plate is moved to the loading position shown'in dotted lines in Fig. 9 to deposit a new primer cap on the upper end of the stem portion 8' for subsequent insertion of the new primer cap into the shell casing S.
. When a desired quantity of shell casings have been provided with primer caps, they are lled with a suflicient quantity of powder and are then reinserted into the press, one at a time, for the purpose of afxing a new bullet thereinto. For this purpose, the ejector means is removed from the die D and replaced by a bullet'press mechanismy '72 as shown in Fig. l1. The bullet press member is similar to thel ejector means in some respects except that its threaded body portion terminates within the die proper above the bore portion 62 thereof and presents thereat a conical bullet nose receiving depression 72', as most clearly shown in Fig. 11. Of course, a stop collar 72" is associated with the bullet press memberl to obtain the proper adjustment thereof. With the die in its uppermost position, a new bullet 65 is lightly pressed into the upper end ofthe neck 66 and then the die is lowered so that the bullet engaging member 72 thereof will force the bullet into the neck 66. The bullet engaging member 72 is properly adjusted when the same engages the nose of the bullet 65 just as the upper end of the neck 66 of the shell casing S enters into the bore 62 of the die. The iinal size of the shell casing neck 66 as occasioned by the die portion 62 is correct for the finished product and, of course, at the same time that the bullet is being pressed into place, the neck 66 of the shell is being reduced slightly in diameter to firmly engage and clamp upon the bullet portion which is projected into the neck.
Fig. 12 shows a means for removing the bullet from a shell casing S should the occasion for such removal arise. This removing mechanism is associated with the previously mentioned die D and includes an externally tapered collet member 67 which has at least a major portion thereof of greater diameter than the bore portion b of the die. The collet 67 is provided with an upwardly projecting bar portion M threaded at its upper end and receiving thereon a wing nut 68 bearing against a washer 68 overlying the upper end of the die member D. When the bullet extractor is used, the carriage 9 is lowered so as to engage the tapered collet 67 onto the bullet 65 and continued downward pressure on the operating means will cause the collet to be forced into the bore portion b and due to the collet taper, the collet will firmly grip the bullet 65. At this point, the downward pressure is maintained on the operating means and the wing nut 68 is screwed up tight so as to retain the gripping action of the collet upon the bullet. The operating means is operated in the reverse direction to withdraw the bullet from the shell casing S.
Although certain specific embodiments of the invention have been shown and described, it is obvious that many modifications thereof are possible. The invention, therefore, is not to be restricted except insofar as is necessitated by the prior art and by the spirit of the appended claims.
