CARTRIDGE-CRIMPER.

SPECIFICATION forming part of Letters Patent NO. 549,553, dated. November 12, 1895.

Application filed September 13, 1895 Serial No. 562,389- NO mof e -l T0 aZZ whom it may concern.-

Be it known that I, \VILLIAM \VAGNER, of the city of \Vashington, District of Columbia, have invented certain new and useful Improvements in Oartridge-Crimpers; and I do hereby 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 it appertains to make and use the same.

My invention, while relating chiefly to improvements in cartridge-crimping heads, also involves improvements in the actuating mechanism of cartridge-crimpers.

In the operation of devices of a class to which my improvements in crimping-heads are applicable the ends of shells to be crimped are inserted into tubular portions or receivers of the crimping-heads,which are provided with suitable inside projections for turninginward the ends of the shells, and with spring-actuated followers, between which and the receivers the ends of the shells are supported with the followers yieldingly bearing against the top or shot wads in the shells during crimping, so as to insure the seating of the wads upon the shot.

Objects which I have most particularly in. view are to increase the durability of crimping-heads, to adapt them to produce perfect crimps, and to prevent bulging, buckling, or other distortion of the shells crimped.

To produce perfect crinips and avoiddistorting the shells, the end of each shell operated upon should snugly fit within the receiver around the follower of the crimping-head or substantiallycorrespond in diameterwith the internal diameter of the receiver not only at the plane of a line drawn transversely through the receiver and touching or close to the advance surfaces of the Crimping projections, but also forward of this plane, or toward the outer end of the receiver, fora distance at least equal to the length of the crimp.

A serious defect in heretofore-employed crimping-heads, in each of which the shellengaging portion of the receiver is designed to be of substantially-unvarying length throughout use, is that when much used they become unreliable or useless by the wearing away and enlargement in internal diameter of the receivers, resulting from frictional contact with the shells, and the wearing away of the crimping projections by excessive frictional'contact with the shells unfits the crimpers for use unless provision is made for the renewal of such projections. Even when, as in an old form of crimping-head, in which detachable pins constitute the crimping projections, provision is made for substituting one set of pins for another, the defect arising from the repeated wear upon the same surface of the receiverthe shell-engaging portion thereof of practically unvarying 1engthstill exists. other defect in crimping-heads provided with spring -actuated followers as usually constructed is that their action on the shells may be prolonged injuriously by continuing their rotation after the shells have been sufficiently turned in at their ends to properly crimp them, with the result that as the followers continue to yield the turned-in ends of the shells are spread out or forced toward the centers of the wads, producing unsightly crimps, bulging the wads, and sometimes distorting the shells so badly as to unfit them for use.

Now, in accordance with my improvements, I provide a crimping-head so constructed that the crimping projections may readily be reshaped or renewed and kept in proper working condition, and so that as wear and reshaping of these projections increase their distance from the end of the receiver into which the shells project new or additional portions of the receiver are brought into use to snugly embrace and properly support the shells in crimping, while extending the surface subjected to wear by frictional contact with the shells. I also provide for limiting the yielding movement of the follower to prevent excessive and injurious crimping action, and, further,-I provide for the reversing of parts to adapt them to act at either end, in order that when objectionable wear occurs at one end the other end may be brought into use. These and other features of my improvements will hereinafter fully be explained and the subject-matter deemed novel specifically claimed.

In the accompanying drawings, which show a crimping-head with my improvements and improved mechanism suitable for actuating it, Figure 1 is a view in side elevation show-. ing the crimping-head with the actuating mechanism; Fig. 2, aview in front elevation ing-head, the detachable section thereof formed with end crimping projections, and the follower of the crimping-head, these views being on a scale somewhat larger than Fig. 3.

A sectional crimping-head which is capable of bein used in connection with a suitable lathe, in the chuck of which it may be secured, or with any appropriate actuating mechanism operated manually or by power is shown constructed as follows: A cartridgereceiver or outer tubular section A of cylindrical form has its bore flared or tapered at its ends to facilitate the entrance into it of the ends of cartridge-shells the external diameters of which correspond substantially with the internal diameter of the receiver for nearly its entire length or between its flaring ends. A hole a is made through the receiver midway its length. A tubular inner section B of the crimping-head is formed to nicely fit within the outer section or receiver and has a hole b through it midway its length to register with the hole in the receiver, so that a readily-removable pin C may serve to detachably connect the two sections. The section B is provided with crimping projections B of any suitable number at its opposite ends, formed in one piece or integral therewith by suitably scalloping it. The projections are properly tapered or rounded off at their extremities and are made of proper length by the formation of the notches b between them to most efiiciently perform their function. By filing or cutting away at the notches b and otherwise properly reshaping the projections when worn by use the section B of the crimping-head may successfully be employed until entirely used up, as farther on will more plainly be made apparent.

A spring-actuated follower D of the crimping-head of a diameter substantially corresponding with the internal diameter of the end of a shell when doubled or crimped is shown as closed or solid at its outer end and tubular for the remainder of its length. It has diametricallyopposite elongated slots (Z in its sides, through which passes the pin 0 for detachably connecting the follower with the outer and inner crimping-head sections A and B. The spring 1) within the follower and bearing at its opposite ends against the follower-head and the connecting-pin G exerts a yielding pressure upon the follower to advance or thrust it outward to the extent of its movement in such direction, which is limited by contact with the cross-pin of the shoul-.

ders formed by the walls of the slots d at their inner ends. Inward movement of the follower when its spring yields to pressure upon the follower-head is limited by contact with the cross-pin of the shoulders formed by the walls of the slots 01 at their outer ends.

The receiver, the section formed with the crimping projections, and the follower are preferably made of suitable steel, so as to resist wear to the maximum extent.

In operation, the crimping-head being mounted in a lathe-chuck or properly supported by any suitable actuating mechanism so as to be rotated and appropriate means being provided for supporting loaded shells so as to be acted upon by the crimping-head, it will be understood that when a shells end is inserted into the receiver of the rotating crimping-head and pressed against the crimping projections to crimp it while the follower bears against the shot-wad that por tion of the shell which is doubled or crimped will snugly fit or fill the space between the receiver and follower and is properly supported, while by positively arresting the illward movement of the follower at about the time that a perfect crimp has been formed, at which time the stop provided by the walls of the follower-slots comes in contact with the connecting-pin, further movement of the shell into the receiver is prevented and it becomes impossible to continue the crimping action upon the shell to an injurious extent. As the crimping projections gradually wear way, (they wear much more rapidly than the receiver wears where it comes in contact with the shells,) the shells are allowed to project farther and farther into the receiver, thus being brought into contact with and supported by new or unworn portions of the receiver and snugly embraced. The inner section of the crimping-head may quickly be separated from other parts and again readily connected with them after reshaping the crimping projections, this inner section becoming gradually shorter as wear progresses and it is filed away in reshaping the projections, and the distance the shells are allowed to project into the receiver correspondingly increasing until the inner section has been entirely used up, after which a new inner section may be employed with the same receiver the wear upon which is obviously slight as compared with that upon the crimping projections, as the surface of the receiver which is subjected to wear by the shells is much greater than the wearing-surfaces of the crimping projections and is being repeatedly added to in use. Thus new inner sections may be successively employed indefinitely, or until appreciable and injurious wear of the receiver may result from long use. As the crimping projections are worn away and the inner section of the crimping-head shortened, while the distance the shells enter into the receiver is correspondingly increased, the slots in the follower are properly lengthened by filing away their walls at the outer ends, so that the inward movement of shells in crimping will not be arrested until at the proper time to prevent injurious crimping action. The follower being connected with the receiver, and inner section of the crimping head by the detachable connecting-pin may readily be removed and replaced.

lVhen the receiver and the section provided with crimping projections are made reversible, to adapt them to be turned end for end, so as to operate at either end, (I prefer to so construct them, although this feature of re versibility may be omitted in one or both parts,) it will be seen that after injurious wear takes place at one end of the parts they may quickly be reversed and used without the delay of reshaping or renewing the projections.

My improved crimping-head may be modified in various respects, and still retain important features of my invention. Among modifications which may readily be made are the following:

Instead of the long or through-pin C for connecting the parts, there may obviously be provided a shorter connecting-pin having a nicked or screw head and a thread for a portion of its length adjacent to its head to engage a thread in the hole a, which may be formed through one side only of the receiver. The unthreaded portion of this form of connecting-pin would pass through the hole 5, which may be formed in one side only of the section having the crimping projections, and through one of the slots (Z (the other slot might be omitted) in the follower and extend across or far enough into the follower to serve as a bearing for one end of its spring.

By the employment of the reversible inner section it is obvious that its projections at one end maybe shaped to form what is termed a square crimp and those at the other end adapted to form a so-called round crimp.

The actuating mechanisn shown by the drawings is adapted to be clamped at the base E of its frame to a bench or table in suitable way, and is provided with a socket or fixed holder F for the bases of the shells to be crimped. A standard G of the frame serves as a support and guide-way for a carrier H in a bearing in which the crimping-head is mounted to rotate, and which is movable up and down this standard. The frame standard projects upwardly from the frame-base in rear of the shell-holder, and is suitably embraced by the rearwardly-projecting portion or horizontal arm of the carrier, so that up-and-down movement may be imparted to the carrier, the bearing in which for the crimping-head is over the shell-holder F, provided in the base of the frame. The outer section or receiver of the crimping-head is provided with an annular groove it, (two such grooves are provided when the receiver is of the preferred reversible construction, as shown,) into which projects the unthreaded end of a screw J, passing through one side of the bearing in the carrier, for properly engaging the crimping-head with this bearing, while leaving the head free to rotate. In accordance with the construction shown in Figs. 1 and 3 the crimping-head is rotated in its bearing in the carrier by means of a crank-handle K, rotating horizontally and fastened to the stud or boss k of a cap or collar L, secured to one end of the receiver of the crimping-head by a screw M, which projects through one side of the cap and engages a hole in the receiver. As shown in Fig. 2, instead of rotating the crimping-head directly by a crank gearing intermediate the crank and crimping-head is employed, an d the crank rotates vertically or about a horizontal axis, the crank being attached to a driving bevelgear N, which rotates about a stud provided at the side of the carrier bearing for the crimping -head. This driving gear meshes with the driven gear 0, suitably secured to the receiver of the crimping-head. To move the carrier H up and down, a pull-rod Pis attached at its upper end to the carrier and eX- tends downwardly through the frame-base, which is provided with openings 13 p, constituting bearings for the pull-rod to reciprocate in. These bearings maintain the pull-rod in an upright position and adapt it to assist in supporting the carrier against horizontal vibration or lateral movement about the frame standard, so that the carrier and consequently the crimpingdiead is always kept in proper alignment with shells in the holder. A spring Q about the pull-rod and bearing at its opposite ends against the frame-base and the reciprocating carrier serves to yieldingly uphold the carrier and to restore it to its normal or most elevated position after being moved downward. Upward movement of the pullrod is arrested at the proper time by contact with the frame-base of its enlarged lower end or bent portion q. To move the carrier downward by its pull-rod and force the crimpinghead into operative contact with the end of a shell to be crimped, suitable means for readily moving the pull-rod against the force exerted byits spring are provided, so that either the hand or foot of the operator may be used, as preferred, for the purpose. To move the carrier downward by the foot, a chain R is shown as attached to the eye formed at the lower end of the pull-rod, and a tubular footrest S, adapted to slide on the chain, provides for forming a stirrup at any desired distance below the pull-rod. The chain is looped, with the foot-rest supported at the bottom of the loop, the free end of the chain being linked to that portion of it above the foot-rest at any desired point, as will readily be understood. To operate the pull-rod by hand, a lever T, having jointed connection at one end with the under side of the frame-base, provided with a handle at its opposite end, and passing through the eye of the pull-rod, may be employed, as plainly shown by Fig. 1.

The operation of the above-described actuating mechanism will be apparent without further explanation.
