' Application filed March 9, 1889. I $en'al No. 302,620. (No model.)

To all whom it may concern.-

Be it known that I, ED IN J. LUMLEY, a subject of the Queen of Great Britain, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Machines for Making Bullets and Shot; 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 it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in means for manufacturing bullets and shot; and it consists in the novel instrumentalities which will be fully understood from the. following description, taken in connection with the'annexed drawings, in which- Figure 1 is a side elevation of my improved machine, parts of the frame of which are broken away and parts of which are in section. Fig. 2 is a top view of the twin spherical bullet or shot forming rolls, showing their journal-bearings and gearing. Fig. 3 is a view in detail showing the shearing device, the guiding or sash frame for the verticallyreciprocating shear, and the shear-bed. Fig.- 4 is a sectional detail view showing a device for adjusting the knife G, and Fig. 5 shows in detail a portion of the bed or platen and one of the beveled side guides fora sheet of lead or other suitable metal. 7

Referring to the annexed drawings by letter, A designates a frame adapted to sustain .the devices'which I shall hereinafter exdrawings coiled or wound about the said roller. In front of this roller is an anti-friction roller a, the journals of which are sustained in notches a formed in the check of the main frame A. The perimeter of this anti-friction roller a at its highest point is slightly above flush with a solid flat bed or platen b, which extends to and terminates at a point as, hereinafter again referred to, and shown in dotted lines, Fig. 1. The object of this platen b is to cause the sheet of metal, after it crosses the roller a, to lie flatly and evenly. In advance of the said roller a,

I show twin rollers c c, the object of which is threefold: first, to spread the sheet or blank ribbon a evenly upon the bed I); second, to feed this ribbon forward in the direction indicated by the arrows on Fig. 1, and, third, to condense and compress the ribbon and prepare it for a further process hereinafter explained. The highest point of the lower feed-roller o is slightly above the horizontal plane ofthe bed or platen b, and this roller is journaled in bearings 0 bolted to the bottom of the top rails of the main frame A.

The upper roller 0 is practically the evener ters of the two rollers c c are strictly parallel and in the same plane as the surface of the bed b. After the compressed sheet a leaves the said rollers I have found in practice that it is liable to buckle up laterally. To obviate this,I employ side guides D, which are open sheath-shaped portions wedging and having laterally-overhanging lips d. At the point ac of these guides D the sheet of metal is cut into strips, as will be hereinafter explained.

On one end of the journal of the feed-roller c is keyed a ratchet-wheel 0 the teeth of which are evenly spaced and pitched, as shown in Fig. 1. WVith the teeth of this Wheel engages a spring-actuated pawl 0 which is pivoted to a longitudinally-reciprocating lever 0 which is pivoted to the main frame on the. stud e. is pivoted to a rod 0", which receives vertical movement from an eccentric e on the horizontal transverse shaft B of a master gearwheel E. It will thus be observed that an intermittent rotary motion is imparted to the lower feed-roller from the said main shaft. The main shaft B is journaled in boxes on standards B rising from the top rails of the The front end of the said lever main frame. Below the discharge-point a: of the guides D is a transverse hopper, which I shall presently describe.

The standards B have on their inner sides tenons ff, (shown in Fig. 3,) which afford vertical guides for a knife-bearing frame G, which receives vertical reciprocating motion from eccentrics g g, keyed on the main shaft, acting through the medium of straps or links g. To this frame G is suitably secured a knife G, which is adjustable and preferably set for operation in the inclined position, my object being to cut the sheet transversely and squarely against a fixed blade G with a clean shearing action. During this act of severing a shot-blank strip from the sheet at its free end will naturally drop. Now, for the purpose of presenting each shot-blank strip evenly to shot-forming rolls II II, I employ my peculiarlyconstructed hopper F, above referred to. This hopper is formed of an inclined rigid wall h and inclined wall 71, which is pivoted at 7L2 to said rail and provided with an arm 1', that is acted on by a spring and bent to form a toe 1", that is acted on at proper times by a tappet 7;, fixed to the shot-forming roll II. This shot-forming roll is journaled in boxes supported by the lower bar of the frame A. On one end of the shaft of the said roll II is keyed a cog-wheel E, which engages with the main wheel E, and which also in turn engages with an idler E This idler engages with a cog pinion-wheel E, which is keyed 011 the shaft of the roll H.

The two rolls H II are provided with grooves 19, which, when each roll is taken diametrically, present a semicircle, the points 1) of both rolls exactly coinciding, formin knifee, 1 edges which cut through and aid in condensing the metal without waste. I I I I I I 1 J is a: funnelfor; the; front roll II I his nnel is closely adapted to the several cor observed that one jaw of the strip-blank hopper F is actuated synchronously with the feed, the cutting-off device, and the final condensing-rolls II II. Instead of giving vibration to the wall h by a tappet 7c and the arm 2 this arm may be extended in an opposite direction, so that it will be actuated directly by the cutter-frame, thus giving a more positive movement to the said wall and at the same time a more sensitive movement. It will be observed that the rollers II II are of the same diameter, and that these rolls are geared so that the roll 11 revolves more rapidly than the roll 11. The object of this is that the strips or blanks are evened between these rolls and cut off squarely. Should both rolls have the same speed, the blank strips falling between them might be cut obliquely and the material wasted.

If desirable, I may use a knife G, which, if desired, is adjustable for the purpose of setting it more or less obliquely to regulate the cut of the shear, and also to nicely compensate for the wear and grinding of the knife, so that the several steps shall be strictly synchronous.

Of course it will be understood that the rollers c c are made of steel and sufficiently 95 :inthe samcdirection at :difierent speeds, as

specified. 1
