The present invention relates to improvements in tools for performing the various operations entering into the Work cycle of reloading an empty cartridge shell.

An important object of the invention is to provide in a device of the above character improved means for introducing the empty shells to the shell holder and then feeding them to the several attachments whereby the various operations of decapping, resizing, recapping, reloading and seating the bullet are performed progressively, en masse, and when the work cycle has been completed the loaded shell is automatically ejected incident to performing the next step in the work cycle.

Another object of the invention is the provision of a tool wherein the actual feeding for accomplishing the several consecutive steps, in the reloading of shells, is performed progressively in a straight line fashion.

Another object is to provide such a tool wherein the mechanism for re-positioning the shell carrier with relation to the shells automatically places them in a position wherein a single simple manual operation places each shell in a position to have the next step in the work cycle of the operation performed upon it.

Still another object is to provide a device wherein the sliding shell holder is interchangeable for diiferent calibre shells.

With the foregoing and still other objects in view the invention consists in certain novel details of construction and combination and arrangement of parts all of which will hereinafter be described more fully and the novel features pointed out in what is claimed.

In the accompanying drawing forming a part of the present application:

Fig. l is a perspective view of my improved tool,

some parts of which are broken away and others shown in section to disclose underlying construction and details.

Fig. 2 is a section taken on line 2-2 in the central part of Fig. 1.

Figs. 3, 4 and 5 are vertical sections respectively thru the resizing, powder attachment and bullet seating dies.

Fig. 6 is a side view of the locking lever and associated parts.

Fig. '7 is a perspective view of a portion of the table structure.

Now describing the invention part by part, I indicates the base, 2 uprights mounted on said base, and 3 is a headpiece supported by said 55 uprights. The base is provided with an apron i having affixed thereto spaced lugs 5 for swingably mounting therebetween a link 6 by means of a pin '5. The base is also provided with bosses 8. Said bosses are tapped and the lower ends of the uprights are threaded and the threaded ends of the uprights are screwed into the tapped bosses. The uprights are notched at 9 to provide a hold for a wrench whereby the uprights may be forcibly secured to the base. The upper ends of the up rights are diametrically reduced to provide a ledge l0 whereon to seat the headpiece and a part of each reduced portion is threaded for the application of nuts 5 l whereby the headpiece may be securely joined to the uprights.

The headpiece 3 is provided with a straight line series of attachments for progressively performing the work cycle of reloading a cartridge-case. Reading from left to right, l2 indicates the decapping, resizing and refiaring die, 13 the powder attachment die, and It the bullet seating die. Each of said attachments are respectively shown in section in Figs. 3, 4 and 5. All of these at tachments are well known in the art. Since no claim is made per se, to them, their detailed description will be omitted for the sake of brevity except where it may be necessary to allude to them later on in describing certain details of the operations.

A table I5 is slidably mounted on the uprights 2. Said table includes a bottom plate l6 provided with bosses l? which encircle the uprights. On the underside of the plate It is provided a pair of spaced lugs l8 between which is mounted and to which is pivoted one end of the connecting rod l9 by means of the pin 20. The other end of the connecting rod is fastened within the arched recess 2| of the link 5 by means of the pin 22.

To the link [5 is secured an operating handle 22a whereby the table l5 may be manually elevated and lowered to operatively relate it with the proper parts at the proper time. I The table l5 further comprises an intermediate plate 23 fastened to the bottom plate 96 by means of cap screws 25 screwed thereinto from the underside, a spacer plate 25, and a cover plate 26. The spacer plate and cover plate are each in turn secured to the intermediate plate by means of machine screws 21. Thru the medium of the spacer plate, there is provided between the cover P te and the intermediate plate a space 28 in which is movably mounted the cartridge-case holding and feeding plate 29.

There is fastened to plate 23, by means of screws 30, a stationary cartridge-case retaining plate 3! which cooperates with the plate 29 in maintaining a longitudinal alinement of the shells with the attachments as the shell feeding plate is manually shifted from feeding position to operating and ejecting position.

The shell feeding plate 29 is provided with a straight line series of shell receiving apertures or notches 32, 33, 34 and 35 for supporting and gripping the cartridge cases 36, 37, 38 and 39. Three of said apertures and their respective cartridge-cases, or shells, namely 32, 3t; 33, 37; and 34, 38; axially aline with the attachments l2, l3 and it during all upward travel of the table. However the apertures which engage the shells in the upstroke do not engage the same shells on the down stroke. The position of the plate 29 with'respect to the shells is shifted during the time the attachments are projected into the shell so that on the down stroke aperture 32 will have been shifted to the left to provide space for another shell. Then the table is ready for reelevating and the corresponding shell being treated will be ready for the next operation in the work cycle. It will therefore be obvious that, on the upward thrust of the table, aperture 32 will be provided with a shell and aperture 35 will be empty,'but on the downward thrust of the table the reverse will be true.

The plate 29 also has a reinforcing and guide lip extension 40 which manually extends beneath the flange M of the plate M. The plate 29 is interchangeable for different calibre shells and when a substitute plate is inserted in the machine the location of the cooperating plate 3i is modified or a different one is used in order that the two will always cooperate to insure an axial alinement of the various shells and the attachments into which they are projected. In the position which the plate 29 occupies in the drawing, shell 38 is in position to be shifted for decapping, resizing and reflaring; shell 31 is in position to be shifted for receiving the powder charge; shell 38 is in position to be shifted for seating the bullet; and shell 39' is in position to be shifted for ejection thru the hole '22 into a suitable container not shown. The shells are all manually shifted in the plate 29 in a battery formation with respect to the attachments and the plate 29 is reshifted automatically incident to disengaging the shells with the attachments after the several operations have been completed on the various shells.

The mechanism involved in performing this cycle of the work will now be described.

From the under side of the plate 23, see Fig. 6, I

downwardly depends a pair of spaced lugs 42 and between said lugs is pivotally mounted a locking lever 43 by means of a pin Q4. The lever 33 is provided with a locking tongue '85 having a cam face 46. Said tongue engages within the notch l? of the plate 29 when the latter plate is manually shifted to the extremeright. In the latter position shells 36, 31 and 38 will axially aline respectively with the attachments l2, l3 and M. The tongue i5 is forced into engagement with the notch M by the spring 48, said spring being mounted on the boss 49 of the lever 13 with its free end bearing against the under side of the plate 23. In the position in which plate 29 is shown, spring 48 is compressed, and the tension in the spring will seat the tongue in the notch M as soon as the plate 29 is shifted to the right. The latter position will be maintained until plate 2!) is automatically shifted frontwardly, at which time the plate 29 will override the tongue 45, on account of the cam face 46, depressing it, whence it is automatically shifted leftwardly to the position now shown.

The headpiece 3 is provided with a pair of downwardly extending pendulously slung levers 50. Said levers are mounted so as to normally hang out of plumb in a direction pointing toward the plate 29 by means of the pins 5!. The levers "39 each have a cam face 52. As the table is elevated the cam faces 52 engage with the inside edge of the plate 29. The levers Elli contact with the plate 29 after the various attachments have been extended into the shells. This engagement of shells with the attachments maintains their axial as well as their longitudinal alinement. During the interval of time the shells and the attachments thereabove are in engagement with each other, the shells are all completely acted upon and thus one step in the work cycle is performed. During this period plate 29 is free to be shifted. Hence during the final stroke of the upward thrust of the table the levers 5&3 automatically shift the plate 29 frontwardly overriding the tongue Q5 of the looking lever 43 until all the notches 32 to 35 are free from their respective shells. Thereupon the plate 29 is automatically shifted leftwardly to the position shown.

The plate 29 is capable of receiving a quadrilateral shift, that is to say a shift along a path which would outline a rectangular surface. The first of these shifts is performed manually to the right; the second shift is performed automatically frontwardly; the third automatically leftwardly; and the fourth automatically backwardly. The manual shift to the right has been described, likewise the automatic shift frontwardly. The mechanism providing for the leftward and backward automatic shifts will now be described.

The plate 23 is provided with a pair of ears 53, between which is pivotally mounted, by means of a pin 54, an actuating lever 55. The lever 55 is substantially L-shaped and is mounted so that both of its free ends are workable. At the end of the levers long leg is provided a pin 55 against which the end of the plate 29 slides when it is automatically shifted frontwardly. When the plate 29 is manually shifted rightwardly, by virtue of this contacting relation, the pin 5 causes the lever 55 to swing about its axis or rotation in a counter-clockwise fashion. The pin 55 is held in yielding contact with the plate 29 by means of a spring actuated plunger 5? which bears against the free end. of the shift leg of the lever 55. The plunger 51 is actuated by a spring 58, there being a cavity 59 in the plate 23 in which both the plunger 5'1 and the spring 58 are housed, the spring 58 being seated the deepest in the cavity. The plunger 5'! acting under the influence of the spring 58 causes the lever 55 to swing about its axis of rotation in a clockwise fashion and causes the pin 56 to shift the plate 28 leftwardly as soon as the arms 50 have shifted it frontwardly out of engagement of both the battery shells and the locking lever.

The plate 29 is provided with a stop plate 66 on its right end to limits its movement to the left and a stop plate 6! on the left end to limit its movement to the right. Each of the plates 6i and 6! bear against the sides of the plate 23 when the plate 29 is either in the extreme left or extreme right position. When in the extreme right position the tongue 45 of the locking lever engages within its cooperating locking aperture 47 to prevent immediate reshifting of the plate automatically to the left by the pin 56 after it has been manually shifted to the right.

A somewhat similar construction to that just described is utilized to shift the plate 29 automatically backwardly whereby the notches in the plate engage with the shells differently to place them in position to be manually shifted to have the next step in the operation performed upon them and at the same time provide for a vacant aperture in which to insert a new shell. The latter construction embodies two additional spring pressed plungers 62 and 63, the numeral 62 indicating the plunger on the right of the table and 63 the plunger on the left of the table. The plunger 62 is housed in the cavity 84 in the plate 23 and actuated by the spring 55 located in the same cavity inback of the plunger. The plunger 53 is housed in the cavity 58 in the plate 23 and actuated by the spring 67 located in the same cavity and rearwardly of the plunger. Each of the plungers 62 and 63 oppose the retraction of cam plates 68 and 69 about their pivotal axes. Said plates 53 and 69 are mounted respectively between the upper and lower jaws projecting outwardly from the stub shafts it and H, by means of pins 12 and E3 which form the pivotal axes for the latter plates.

The plates 68 and 69 are each provided respectively with stud pins 74 and i5. Said pins are yieldingly held in abutting contact with the outside edge of the plate 29 under the action of springs 65 and 67 thru the medium of the plungers 82 and 63. The plungers $2 and 5% tangentially graze the cam faces of the plates 68 and 69 to initiate contact of the pins M and "15 with the plate 28 at all times.

When the arms 5t automatically shift the shell holding plate 29 frontwardly, springs 55 and iii are compressed so that as soon as the slots in the plate 29 have cleared the shell, the locking lever has depressed the lever 55, and the lever 55 has shifted it leftwardly, the pins M and '35 will automatically shift plate 29 backwardly thus completing the quadrilateral shift of the shell holding plate. This quadrilateral shift occurs each time the table is elevated and each time the shell holding plate is shifted to the right on the initial stroke of the quadrilateral shift, when once filled with shells, it will automatically discharge a completed shell thru the discharge aperture 76. This cycle may be repeated ad infinitum.

In the four major operations of reloading a shell one of these major operations is performed on the down stroke. This operation is that of recapping and is performed immediately after the shell has been resized and decapped. Mechanism whereby this operation is performed comprises the following.

On the front face of the apron t is provided a shelf ll. Into said shelf is screwed one end of the primer stem it and held fixedly thereto by means of a lock nut 19. Around the stem i8 is coiled a spring til, and a sleeve M is slidingly mounted on said stem and adapted to seat upon said spring.

The sleeve 85 carries a primer reservoir 82 from which primers 233 are fed thru the mouth 84 so as to seat upon the end of the primer stem. The sleeve fill and primer reservoir 82 move upwardly and downwardly thru the slot 35 located in the bottom plate iii, see Fig. 7. The sleeve travels upwardly under the action of the spring to permit the deposit of a primer on the end of the primer stem once the table is elevated after it has been depressed.

There is an aperture 86 in the plate 23 which axially alines with the shell as well as with the attachment l2. This aperture is slightly larger than the free end of the primer stem 8? which carries the primer thru said aperture, but is of smaller diameter than the shell 31 which is seated on the plate 29 thereabove. The upper end of the sleeve 3i bears against the under side of the plate 23 to yieldingly support the table if) thru the medium of the spring 80. A set screw 88 may be employed to limit the travel of the sleeve so that a primer will always be fed on to the end of the plunger.
