CARTRIDGE PRIMING OR DEPRIIVIING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 68%,150, aaa September 24, 190i.

Serial No. 64.}984. (N0 model-l To (all whom it Til/(by concern.-

Be it known that I, IRA SILVIS, a citizen of the United States, residing at Grafton, in the county of Yolo and State of California, have invented certain new and useful Improvements in Cartridge Priming or Depriming Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to an apparatus for priming and depriming cartridge-shells; and its object is to provide a convenientand efficient construction of apparatus whereby the operation of priming and depriming carperformed.

\Vith this object in view the invention consists in certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly pointed outin the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of a cartridge-shell priming and depriming device embodying my invention. Fig. 2is a front elevation thereof. Fig. 3 is a rear elevation. Fig. 4 is a top plan view, the shells appearing in section, showing the parts as arranged at the beginning of the priming and depriming operation. Fig. 5 is a similar view showing the arrangement of the parts at the end of the operation. Fig. 6 is a bottom plan view of the device with parts arranged as in Fig. 4. Fig. 7 is a horizontal section through the base of the feedhopper, its supporting-frame, and the shells fed up to be primed, said section being taken on the line of the feedppenings in said frame. Fig. Sis a vertical section of the same on the line 8 8, Fig. 7. Fig. 9 is a vertical cross-section through the frame and carriage, and Fig. 10 is a horizontal section through the hopper. Fig. 11 is a fragmentary end view of the bedplate, showing the application of the box 6 thereto, the box appearing in transverse section; and Fig. 12 is a perspective view of the box.

Referring now more particularly to the drawings, the numeral 1 represents the bedplate or supporting-frame of the apparatus,

which is provided with a clamp 2 for attaclr ment to-a table or work-bench and is formed upon opposite sides of its upper surface with flanges or stop-ribs 3, which hold the cartridge-shells placed thereon against lateral or sidewise movement preliminary to the feed ing up of the shell-holders, hereinafter de scribed. The shells are designed to restupon the u pper surface of said bed plate, which may be of anydesired width to contain any humber of cartridges and has at its forward end a groove 4:, in which the rim edges of the car tridge-shelis are adapted to fit. On one side of the center and at the rear end of the bedplate is arranged a stop flange or shoulder 5, against which the closed ends of the shells which are to be deprimed are adapted to bear, and in the rear of said flange and spaced therefrom is located a second flange 6. A box (5 is slidably and detachably connected to one or both of said flanges to receive the primers forced from the cartridge-shells and is provided with a stop-plate 6 to arrest the shells as they fly out.

A carriage 7 is rigidly secured to the outer ends of two guide-rods 8, which are arranged to slide in openings 9, formed in the bed-plate 1, and from said carriage projects a series of parallel guides and holders 10,

which are adapted to be fed up by the move-' ment of the carriage to retain the cartridgeshells in position and to act also as depriming devices and anvils to assist in the operation of depriming and priming said shells. In the present instance four of such guides and holders are shown employed-two for priming and two for depriming purposes. The two priming guides and holders have projecting ends 11, which serve as anvils in the manner hereinafter described, and the two depriming holders and guides have mounted therein the depriming-pins 12, formed upon or secured to screw-threaded stems or shafts 13, adjustably mounted in screw-threaded openings in the said ends of the guides and holders and having their free ends slotted, as at 14:, for the reception of a screw= driver or other tool applied thereto for adjusting them. The pins 12 when dulled or blunted may be dresseddown sojas to form a sufficiently sharpened point or surface for the extraction of the primers.

To one of the guide-rods 8 is jointed, by means of a pin 15, one end of an operating handle or lever 16, which is adapted to be drawn rearwardly to move the carriage 7 into operation and to be forced inwardly to retract the carriage, the inward movement of said parts being limited by a stop-flange 17 on said lever. The lever 16 is adapted to slide within the opening, in which the acting rod 8 is movably mounted until the carriage reaches the limit of its outward stroke, and then to be forced down on its pivot so as to bear against a bracket or extension 18 upon the bed-plate to exert a more powerful pressure or leverage at theinstant of forcing the primers into the shells to be primed and extractiug them from the shells to be deprimed. The bracket 18 is disposed upon the opposite side of the center of the bed-plate 1 from the flanges 5 and 6 and is formed at its outer end with a fixed head or block 19, in which is mounted two forwardly projecting guidepins 20,0n which is fitted to slide the movable primer-head 21. This head is composed of front and rear plates 22 and 23, said front plate being provided with feed-passages 24, which communicate at their lower ends with feed-openings 25, opening through the inner or front surface of said'plate, and in communication with corresponding openings formed in a supporting-frame 26, secured to the plate. The guide-pins project through openings 27, formed in the rear plate 23 of the head and which communicate with the said feed-openings 25. The pins 20 are thus adapted to work through the communicating openings 25 and 27 and to guide the primer-head in its movement. \Vhen the primer-head is forced back, the inner or forward ends of the pins 20 project into the feed-openings 25 and serve as anvils to sustain the primers, being formed for this purpose with concavities 28 in their ends to receive the head of the cap of the primer. When the primer-head moves inwardly or toward the carriage 7, the feedopenings 25 are no longer closed by the pins 20, and primers from the hopper may therefore feed down into position thereinto for operation.

The supporting-frame 26 is provided at its upper end with an open-work guide 29, between which and said frame is slidably fitted a movable feed-hopper 30, which is supported by the primer-head 21 and guided in its movement transversely of the bed-plate 1 by the said open guide member 29. The hopper 30 comprises in its construction front and back plates 31 and 32 and vertical end pieces 33, which act asspacers to hold said front and back plates apart. The said plates are also held apart between the end pieces by vertical partitions 34, which forms a series of feed chutes or passages in which the primers are placed to be fed to the primer-head for application to the shells to be primed. The feed-chutes 35 are adapted to be brought into coincidence with either one of the feed-pas scaled sages 24 in the primer-head by sliding the hopper 30 laterally on said primer-head and to hold the feed-hopper stationary when in adjusted position with two of the feed chutes or passages in line,with the passages 24. A spring-pawl 36 is provided upon the guide frame or member 29 to engage seats or notches 37, formed in the upper edges of the front and back plates 31 and 32 of said hopper. In the plate 32 are formed a series of peepholes 38, through which the feed of the primers through the feed-chutes maybe inspected, and in the lower edge of said plate are formed slots 39, through which project a seriesof curved fingers 40 upon the lower edge of an apron 41, pivoted to the hopper, said fingers acting in the nature of detents to prevent the primers from dropping down through the feed chutes while said chutes are being filled. The shaft 42 of this apron is extended at one end to form a handle or finger-piece 43, whereby the apron may be opened to allow the primers to feed down, and a spring 44 is secured to thehopper and acts upon the said shaft to normally hold the apron closed with the said curved fingers projecting into the slots 39. In operation by sliding the hopper transversely of the bed-plate 1 on the primer-head 21 the lower ends of any two adjacent chutes therein may be brought into connection with the feed-passages 24, and when these are exhausted the hopper may be adjusted to bring two other feed-chutes in communication with said passages in a manner readily understood. The primer-head 21 is normally forced away from the head or block 19 by an interposed spring 45, and when the primer-head is forced inwardly or rearwardly by this spring the guide-pins 2O lie in rear of the feed-passages 24 and feed-openings 25, so that the primers in the feed-chutes communicating therewith are free, when the detents 40 are moved outward to feed down into said passages 24 and openings 25 in position for use in advance of the inner ends of the pins 20.

The operation is as follows: In depriming and priming a number of shells a pair of shells to be deprimed are first rested on the bed-plate 1 with the closed or headed ends of the shells bearing against the stop-flange or shoulder 5, the rim flanges of the shells seated in the groove 4 and the outermost shell bearing against the adjacent side flange 3. The operating handle or lever 16 is then drawn outwardly to cause the holders and guides 10, carrying the depriming-pins 12, to enter the open ends of the shells, and this movement is continued until the deprimingpins 12 come into engagement with the primers, when the pivoted end of the operatinglever projects outward from the guide-opening 9 and said lever is left free to be forced downwardly. The lever is then forced downward and its free end is brought to bear against the bed-plate, which acts as a fulcrum therefor, whereby greater leverage may IIO 2o guides 10 into the shells.

5 the stop-plate 6 of the box 6, which prevents them from being scattered, and then drop down into said box to be saved for further use. The two cartridge-shells thus deprimed are then moved to the opposite sides of the 10 bed-plate 1. for priming and two other cartridge-shells seated in the place formerly occupied by them for depriming. The apron 4.1 is then operated to withdraw the fingers 4.0 from the feed-chutes 35 to allow primers :5 from the two feed-chutes in line with the feedpassages 24. to drop down and to be exposed at the feed-openings 25. lhe operating-lever 16 is then again operated in the manner heretofore described to force the holders and When the lever is moved to the limit of its outward stroke, the pins 12 on the two depriming-holders 10 are brought to bear upon the primers of the shells cooperating therewith, while the projecting 25 ends or anvils 11 on the two other guides and holders 10 have forced the primer-head 21 backward against the head or block 19, thereby bringing the guide-pins into the feedopenings and forcing the primers outward until they are seated in their places in the heads of the shells. The anvils 11 of the two priming-guide holders 10 will then bear upon the priming-chambers of the shells to reinforce them while the primers are being seated The operating-lever 16 then being at the limit of its outward-sliding movement is adapted to be forced down, and when forced down the pins 12 expel the primers on the shells to be deprimed, while the anvils 11 force the head of the shells to be primed tightly against the priming-head 19 and force the latter farther backward, thereby causing the pins 20 to be farther projected and to seat the primers within the chambers in the heads 5 of the shells. Upon then elevating the operating-lever 16 and sliding the carriage 7 backward or away from the primer-head 21 the holders and guides 10 will be withdrawn from engagement with the cartridge-shells and the primer-head retracted to its normal position by the spring 45, ready for a repetition of the operation above described. The primer-head 21 is limited in its rearward movement by a stop-pin 46, and the shells are prevented from The feed-passages 24 and feed-openings 25 in the primerhead are preferably arranged to slope in order to provide for the proper feed of the primers as the shells increase or decrease in size.

derstood without a further extended explanation, and it will be seen that a simple, durable, and eifective device is provided ,whereby the operation of priming and depriming cartridge -shells may be easily and quickly performed.

While the preferred embodiment of the invention is as herein disclosed, it will of course be understood that changes in the form, proportion, and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.
