TO ALL WHOM IT MAY CONCERN: t h

YBe it known that I, DEXTER SMITH, of Springfield, Hampden county, Commonwealth of Massachusetts, have invented certain new and useful improvements in Machines for Heading and Cutting off Metallic Cartridge Gases; and do hereby declare that the following is a full and exact description of the same, reference beinghad to the accompanying drawings and tothe letters of reference marked thereon. i My improvements consist in combining the operation of trimming the shell to the required length, andthe operation of heading the same in one machine and transferring the shell from the mechanism for trimming to` the mechanism for heading automatically by means of devices which Iwill hereafter describe; also, in a peculiar arrangement of mechanism for operating `the cutting-oli' tool, and in an improved chuck for holding and revolving Vthe shell while it is being cut off. These improvements are shown in the drawings which accompany these specifications, in which- Figure I is a plan view of my improved machine.

Figure 2 is a perspective view of the same.

Figures 3, 4, and 8 are detailed views of the chuck.

Figure 5, a side view of the device for stopping the disk.

Figures 7 and 6, views of the shell after and before heading. p f

A is the bed of the machine, to whichthe other parts are attached. B is the shaft to which power is applied at C, and from which the moving parts derive motion by means of suitable connections. At the oppo` site end of the bed from the shaft, B, and supported by suitable bearings, I place `the shaft, D, to which are attached the arms, E F` G. Motion is given to this shaft from the cam, H, on the shaft, B, by means of thc connection, I, supported by the lever, J, and" the sliders, K L, are operatedby means of connections, M N, pivoted to them and to the arms, E F. The slide, K, carries at one end a punch or mandrel, S, and works through the piece,ib, which has a slot, c, formed in it, into which the cartridge ca'se is dropped, andthe punch, S, coming forward carries the case along into the chuck, O, which is of Va peculiar construction, and will be more fully described hereafter. After it is inserted in this chuck, it is revolved by power` applied at the pulley, d, and the tool, Z, being forc'ed up by the lever, X, operated from the shaft, B, by thecam, Y, chts or trims off the shell, thus forming itof the desired length. After this is done, the mandrel, S, is withdrawn and forces another" shell in by a series of movements similar to that just described, and the previously inserted shell is pushed out` h through the centre of the pulley, d, and intoa hole in the disk, P. This disk is now partially revolved byi` means of the rat'chet,vg, and pawl, h, operated by Athe cam, K, by means of suitableconnections, and is stopped by means of the catch-pisode,springing-into notches 1, 2,3, Snc., in the edge of the disk, P. `Just before' motion is given to the disk this catch-piece is thrown out of the notch by means of the lever, y, under the bed h of the machine, operated by the cam, 0. After the disk P has been revolved far enough to carry the shell iirst h i trimmed around opposite the punch, R, it and'each successive shell are forced into the die, S, by this punch, R, operated from the shaft, D, by means of the arm, F, and connection, n, and the-heading-punch, T, is forced up against the closed end of the shell from the oppositeside, operated from the shaft, by means of the'cam, p,

and the head or rim, a, is formed, leaving `the shell in the shape shown in fig. 7,`readyifor filling.` The mandrel, S, is constructed in' a peculiar manner, having at its end a collar, c, which entersthe shell, and which part alone 1 revolves, and not the whole of the mandrel, as scommonly the case. The construction of the chuck, O, now

remains to be described. This is shown in the drawings, at figs. v3 and 4; g. 3 being a face view of thc chuck i i l with the cover removed, and fig; 4 being a cross-section through the same. It consists of two pieces, U', i inserted in a slot in the body of the chuck,'and having a hole in the centre for the insertion of the cartridge;

these pieces, U are kept together by means of springs, W, on one or both sides, the tension pf which isgoverned by the set-screws, a: fr', so that when a shell is pressed into the opening in the chuck it is `held `there by the pressure of the springs, thus allowing for slight variations in the shells'. I insert the die, j, in the face, as shown in iig.` 8, for the purpose of guiding and centring the shell in its entrance into the chuck.

Iam aware that machines have been made in which these operations I have describedl have been performed,A

but never, to my knowledge, have they been combined so as to work automatically together, taking the shell in the form shown in fig. 6, and leaving it in the form shown in iig. 7. This Ihavc accomplished by thc arrangement of the machine, and by placing the disk, P, as' shown, and operating it to transfer the shells fromonc side to the other, as Ihave described and in this, and the peculiarities of construction I have described, my improveh ments consist. lso, in thepcculiar arrangement of the mandreLS, with the devices for operating it in connection with the tool, Z, and devices for operating that, I have a great improvement, for the cani, H, isan eccentric; and `when the part, z', of the connection which Works'in the groove in the side is nearest the centre, and while the cam is moving, the mandrel is stationary, and the tool, Z, is so arranged that at just this' time it is forced up by the cam, Yand cuts the shell while the longitudinal motion of the mandrel is stopped. This being done, the cutting-tool is immediately withdrawn and the motion of the mandrel recommenees. do not wish to confine myself` to any particular device for transferring the shell from one side of the machine to the other, as instead of the disk, P, I can use a. slide or oscillating arm.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. 'I claim the Adisk P, operated from the shaft B by means of the cams K and O, connected with the ratchet and pawls gJL, and stop-piecem, or equivalent mechanism for the purpose of transferring'the shells, substantially as herein set forth. i

2. The combination of the cam H, shaft D, and mandrel S with the cam Yand tool Z, when arranged and operating substantially and for the purpose as described.

3. The chuck O, constructed as described and used for the purpose of holding the shells, as set forth.
