T0 ALL Wil-IOM ITV MAY CONCERN: Y e

Be it known that I, ANDREW J. FRENCH, of Waterbury, in the county of New Haven, and State of" Connecticut, have invented a new and improved Machine for Lining Percussion-Caps; and I do hereby declare that the Vfollowing is a full, clear, and exact description thereof', which will enable others skilled in the art to make anduse the saine, reference being had to the accompanying drawings forming'part of this specification.

The .object of this invention is to construct a' machine whereby percussion-caps may be lined with tin-foil in a rapid and satisfactory manner, the machine being simple and compact, and cannot easily get outof order.

The invention consists in the use of a horizontal sliding plate, which is provided with holes which are arranged in rows, and in which holes the caps are placed. A punch is brought down into each hole, lining all the caps in succession, the punch moving on a stationary guide across the said horizontal plate-[so as to come over each holo in one row of holes in the plate. When one row has been lined, the plate is moved so that the next rou` is brought under the punch, which moves along this row, lining each cap in the same. All the Inovements are automatic, and all the parts are moved at the proper` time and in the proper direction by simply revolving the driving-shaft. The devices for moving the punch back and forth across the plate, and also the device for fecding the plate under the punch, constitute the main features of my invention. In the annexed drawing my invention is illustrated- Figure 1 being a plan or top view, partly in section, of my improved machine for lining percussio'rrcaps.

Figure 2 is a longitudinal vertical section of the seme, the pla-ne of section being indicated by the line :r af, iig.

Figure 3 is a vertical crossseetion of the same, taken on a plane indicated by the line y y, iig. 1.

Figure 4 is a detail view to be hereinafterreferred to.

Similar letters of reference indicate like parts.

A represents a bedplate, made of cast iron or any other suitable material. On its sides arc arranged projecting metal linings, a, in which are grooves for guiding a metai plate, B, so that thc latter can move from end to end of the machine. The plate D is perforated with holes which are arranged in rows, as shown in fig. 1, said rows being numbered from I to 15 respective-ly in the drawings. The holes in each of these rows are arranged exactly inline with the holes in the other rows, as shown. C'C are tivo upright posts or supports, in which are arranged boxes for the horizontal shaft D, which is arranged across the plate B and above the same, as shown. Rotary motion is imparted to the shaft D by a belt running over a pulley, or otherwise. E is a stationary frame, cast with or securely attached to the bed A, being arranged parallel with the shaft D, and near to the same, as shown in the drawings. To the face of this frame E, between the same and the shaft, is attached a dove-tail tenen, d, extending the whole length of the said frame. This tenen fits into a corresponding groove in a sliding frame, F, which is mounted on a sleeve, e, on shaft D. The sleeve e is provided with a feather, which fits into a groove arranged along and in the shaft D, as shown in figs. l and 2, so that the sleeve must revolve with the shaft and Within the frame F, the latter being held in position by the tenen d, but the sleeve may also slide on the shaft, and being provided with shoulders on each side of the frame F, the latter must slide with the sleeve. On the sleeve e is firmly secured a dislr, G, the rim of which fits between the teeth of a rack,f, which is arranged en the frame E. 'One portion, g, of the rim of this disk G is hinged in such a manner that its end can be moved to either side of the disk, thereby making the rim of the disk spiral or screw-shaped. The part g, which may constitute more or less than a quarter of the circumference of the disk G, as may be desired, is pirated to the bodyof tho disk by means of a pin, 7i, (shown in dotted lines in Iig. 2,) and can be turned on the said pin, sothat its other nonlpivoted end may be swung either to one or the other side of the disk, In the disk G is pivotcd, opposite to the free end of the swinging portion g, a plate, z', which is provided with a pin, K,

which ts into the part g. Both ends of the plate t' are projecting beyond the face of the disk, as shown in g.

, which is a detail sectional vieiv of this portion of the disli, .As the plate i is turned on its pivot it swings the rimrg, by means of the pin I{, to one side of the dish. From the'above it is obvious that for changing the thread of the screw, formed by the disleG and rim g, it is only neccssfiry to strike one end of the plate 2', and so swing the said plate around its pivot. The swinging pieceg is prevented frombe'ing turned too much by stops a ct arranged en either face of disk G, as shown, and the piecog is steadied, guided, and strengthened by the use of a dove-tail tenon, 6', which is pivoted te the disk G, and fits in a groove in g, and turns on its pivot as the picceg swings to one side. 0n lthe horizontal sliding frame F is arranged a vertically sliding punch, H, which receives reciprocating motion from an eccentric, Z, on shaft D, to which a counecting-red, au, is Secured, the upper endoi" which is attached to a frame, n, which holds the punch. The said frame -n is slotted so as to move up and down without coming in Contact with the shaft D. The proportions of the parts are such that the punch is moved across the plate B by means of the worm G engaging between the teeth of the barf just as far as one hele in cach row is from the other, and after having arrived over a hele the punch is moved down into the hele, and lines the cap therein, some tiirfoil being, for that purpose, fed below the punch. The thread of the worm G is changed, when the punch arrives at the end of a row, hy'inenns of stops o o', with. which the extremity of the plate lz' comes in contact, and whereby the pnrt g is shifted. The punch would then be moved across the plate D again, but in the opposite direction. As soon as the last hole in a row is made the plate B is moved forward by a mechanism hereinafter to be described, so as to bring the next row below the punch. But if thc punch. would move directly back after having lined the last cap in a row, the first cap in the next row would he omitted. For the purpose of avoiding this inconvenience, I have made the rachf in the form of a bar whichfits in a groove in the tenen c7, as shown. At each end the groove is closed by stopspp, which arc made in the form of heads of screws or otherwise, and the barf is as much shorter than the groove as the distance is from hole to hole in each row, the barf being thus enabled to slide in the groove. "When the punch is, for instance, moving on the shaft D towards the pulley Ii, the rack will, by the Vshape of the thread of the worm, be always pressed against thc step y on that end from which the punch has started. As soon as the punch arrives at that end of tho row which is nearest the pulley L, the thread ofthe worm G will he changed by the stationary stop 0 at that end ofthe machine, but at the next revolution ofthe shaft Dthe punch will not nieve back yet, but the worm will, by means of its reversed thread, draw the bar j' towards the stopn, which is on the same end of the frame d on which the punch is standing. During the revolutionof the shaft' D which was required to shift the bar f, the plate B has been moved forward se as to bring the next row of caps under the punch, and as soon as the rack is shifted thc punch is forced down into the first cap in the new row. r.lhcn the punch moves on the shaft D again, and is forced successively into each cap into the row until it arrives at the other end of 'thc row, when it will again he held during the shifting of the plate B and rackf, and he forced into the cap at the end of the next row, when it will begin to slide baclr'agnin, and so forth, until all the caps in the plate B have been lined. The revolutions of the shaft D -arc thon stopped, the plate B refilled with caps and moved hack on the bed A until the row No. 15 is below the punch, when the op rations will again begin as before. The stops o o may be arranged in any desired manner, either stationary, as o, or flexible, as o'. The latter is represented in the drawing as being a rod with an inclined surface, which presses, as the punch comes near it, against a pivotcd bar, o, on the frame F, said bar o having a pin which strikes against the plate t' as soon as o is moved in by 0. A spring throws o into the original position again as soon as it is released from o. But any other suitable stop arrangement may bc employed, a stationary one being the simplest form, as shown at o. i

I will new proceed to describe the device for feeding the plate B forward, se as to bring each row of caps under the punch at the proper time and in proper order.

To one side of the plate B is secured a^toothed bar, 1], the teeth of which are engaged by a pawl, r, which is arranged on a swinging bar, The latter is hinged at its upper end to a slotted bar, S, which is secured to the stationary frame E by means of serws, as is shown in gs. l and 2. On one side of the bar I arranged a projecting pin, t, which is by means of a spring, it, pressing against thc bar I,'presscd against the periphery of a disk, L, which is mounted en a horizontal shaft, M, as shown.

The shaft M is mounted in lboxes which are arranged in arms extending from the frame E, and receives intermittent rotary mot-ion from a pawl, V, attached to an eccentric on the end of the shaft D, which pawl moves a ratchet-wheel, u', on the end of shaft M. The said ratchet-wheel has as many teeth as there are holes in each row on the plate B,so that as it is moved one tooth during each revolution of the shaft D, it makes one rever lution, while the punch moves from one end to the other of the plato B. The simple revolution of the shaft M has no effect upon the pawl i' cr plato I5, but as one revolution is completed thc pin t on the bar I is pressed by the spring 'u into a recess or depression, X, which is arranged on the periphery of the disk L. lThereby the pawl ls thrown into a notch inthe bar g, and when at the end of the recess thc pin tis thrown against the real periphery of the disk L, the pawl is drawn back and pulls the bar q and plate B with it, so that new row of caps is brought under the punch, as soon as one row has been finished. Although this device for feeding the plate B is new, and part of my invention, I do not wish to confine myself to its use, as many other devices may he arranged on this machine which will work equally well, while the device for feeding the frame F can hardly be simplified.

What I claim as new, and desire to secure by Letters Patent, is-

1. The reversible worm G with its sleeve e working upon th'e grooved shaft D, and provided with an oscil- Mlating dog, g, substantially as set forth.

2. The device for feeding the frame F, consisting of the sleeve e, worm Gr, ratchet-barf, shaft D, all made and operating substantially as herein shown and described.

3. The sliding toothed barf in combination with the reversible worm G and stops o o', for the purpose of retaining the punch in position so as to line the first cap in a new row, all as set forth.

4. ylhc device for feeding the plate B, consisting of the recessed disk L on shaft M, and of the pawl 7' on swinging frame I, all made and operating substantially as herein shown and described.
