IMPRQVEMENTIN FLouR-BOLTING REELS.

Specificationforming part of Letters Patent No. 116,331, dated May 30, 1,871.

Be it known that LFLTCH B. LEWIS, of Tifin, in the county of Seneca and State of Ohio, have invented certain Improvements in Bolting-Reels; and I do hereby declare that u the following is a full, clear, and exact description thereof, reference being had' to the accompanying drawing making part .of this specification, in which- Figure 1, `Plate l, is a top view ofthe reel las seen" by removingthe upper half of the reel-chest. Fig. 2, Plate 1, is a view of two hammers and their actuating mechanism,

showing the hammers raised from their anvils ready to strike. Fig. 3, Plate 2, is a cross- `section of the boltin g-chest and the reel. Fig.

4, Plate 2, is a perspective view of a hammer and its rod. Fig. 5, Plate 2,is a perspective view, showing the Wedge-cam, and also an antifriction roller on one of the actuating-rods.

Similar letters of reference indicate corresponding parts in the several figures. This invention relates to improvements on mechanism for operating hammers or knockers upon a bolting-reel for the purpose of jarring the reel during the operation of bolting flour. The nature of my invention consists, first, in crankin g each hammer-handle insuch manner that the handle serves as a pivot for the hammer, and also a means whereby the hammer can be operated `by a rod having an4 endwise motion, as will be hereinafter explained; second, the anvil-bed, constructed arranged inside of the reel, at one end thereof, as to be capable of adjustment for regulating the force of the blows of the hammer upon u their anvils; fourth in providing each actuating-rod with an anu-friction roller and applying this roller to a detachable socket, as will be hereinafter explained. y i

To enable others skilled in the art to understand my invention, I will explain its construc- In the accompanying drawing, A represents a bolting-chest, withinwhich a reel is arranged to rotate freely. This reel may be constructed Vin the usual well-known manner. It consists ofa central shaft, B, from which arms C -0 otal portion, b2.

radiate, which have attached to them the reel bars or ribs D D, six, more or less, in number. G G are the hammer-actuating rods, two of which are represented in the drawing, arranged on opposite sides of the reel and parallel to the reel-shaft B. As the hammer mechanism is precisely alike on both sides of the shaft B, I will, for simplicity of description, refer to the mechanism on one side of this shaft. The rod G extends nearly the whole length of the reel, andnear one end it passes through an arm, g, and is guided by said arm. That end of the rod G nearest this arm has a socketbearing, r, securedon it by means of a setscrew, V; and to the end of this socket-bearing an anti-friction roller, p, is applied, which rolls against the surface of a cam-segment, L.` By thus applying the roller to a'removable piece, r, it will be seen that when the pulley wears out its place can be readily supplied Without detachin g the rod G. The cam L, whichk gives endwise motion to the rod G, is a beveled segment, which is hung inside ofthechest A, at one end thereof, and which can be adjusted for giving more or less throw to said rod by means of a rope or chain, m. VThis segment L is pivoted at t, so that it can be adjusted Within the range of the pulley p onrod G, as the pulley revolves with the reel. The drawing shows the rope m attached directly to the segmentL; but a modication of this plan would be to apply an arm to the back of thesegment and attach the rope to the end of this arm. To the reel-rib D, inside thereof, I securenarrowanvil-beds J J, each one of which has an anvil, j, formed on one end, and an eyebearing, t', formed on the other end. To e'ach bed J a hammer is pivoted in the following manner: a represents the hammer-head, and b its handle. The handle is bent at three points, x m x, V(see Fig. 4,) in such manner as to form the pivotal part h3, which is received by the` eye-bearing i; also a crank-arm, b1, and a piv- The arm portion extends from the eye-bearing t' to the inner end of van attaching-block, c, Which is made fast to the rod G by a set-screw, s. Thus it will be seen that each hammer is attached to the anvil-bed J and to a block, c, on the actuating-rod G, by means of a single rod, which is bent so as to form the pivotal connections and the crankarm. The hammers are held down upon their anvils by means of a spring, S, applied as clearly shown in Figs. l and 2.

Having described my invention, I claim- 1. The hammer-handle, cranked at x a: so as to form the pivotal portions b3 b2, and the crank-arm b1, in combination with the eyebearing z' and the attaching-block c, and the endwise movable rod G, substantially as described. 2. The combination, with the bolt-bar D, of the rod G, anvil J provided with raised p0rtion j and eye i, hammer a having crank-handle b b1 b2l and actuated by spring S, when constructed, arranged, and operating as shown and described, for the purpose set forth.
