'lO ALL .WHOM IT MAY OONCERN:

Bo it known that we, HENRY GROSS and JESSE B. RUMSEY, of Tiflin, in the county of Seneca, and in the State of Ohio, have invented certain new and useful Improvements in Mill-Bolts1 and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,

In the annexed drawings, A represents the bolting-chest, which may he made in any of the known and usual ways. The bolt or reel, composed of the heads B B B', the ribs D D, and the centre-shaft C, is placed in the bolting-chestin the usual horizontal manner. The heads B B B are provided with square openings at their centres through which the square shaft O passes looselyil ci represents a coiled wire spring which surrounds the shaft C, as-seen, being stationed at one end by a pin, e, which passes through shaft O', and pressing at its other end against the head B. This spring serves to keep the heads with ribs attached pressed toward one end of the holting-chest all the while. Secured to one of the heads B is a small wheel, a, with a cam or series ol' cams on its outer face, as shown. t' represents a corresponding Wheel with cams facing those on wheel a. This wheel z' has a round hole through its centre, and ts over a round portion of shaft O, near its end. .I represents a rod, bent, as seen, with one end passing through al slot in the end ofthe chest A.. A pin on the "wheel t' catches against the cud of this rorl, when desirable, for the purpose of stopping the said wheel from revolving on the shaft C. The object of the two cam-wheels a andz'is to give a longitudinal motion to the reel. The coms on the wheels press the reel-frame in one direction until the shoulders on said wheels come opposite to each other, then the frame jumps back suddenly by pressure of. the spring d, and thus gives the frame an endwise or longitudinal bumping motion, which tends to shake the flour through the bolting-cloth on the reel. By moving the rod J, its end may be prevented from stopping the wheel z', and said Wheel may revolve, in which case no endwisc motion will result. H represents a metallic rod which runs through the chest, from one end to the other, outside of and parallel with the reel. Surrounding this rod is a coiled wire spring, l, which one end secured to the rod H, and the other end secured to the side of the bolting-chcst. Secured tothe rod H, and opposite the three heads BBB, are three arms, m, which have to their lower ends the hammers or knockers n. Ereprcsents a metallic spring, one end of whichis secured to thc rod H; the other end is heut, as represented, and passed through an opening in said rod H. A sleeve, G, passes over the rod H and also over the spring E. A lever, F, with a slotted end, catches with this slotted end over an ear on thc sleeve G, and serves to move the collar or sleeve. By pressing the sleeve in one direction the spring E is pressed toward the rod H, and by moving it in the opposite direction the spring moves away from the rod. A series of pins, S S', on one of the heads B, catches against the end of spring E, when it is desired, and thus causes the rod H to make a partial revolution. As soon as the pin has moved far enough t slip oli" from the end of the spring, the spring I causes the rod J to partially revolve in the opposite direction, and thus bring the knockers in sudden contact with the heads oi' the reel. By the jar caused hy the striking oi' the knockers against the reel the ilour is made to sift through the bolt.

It will be seen that by the use of the knockers and by vibrating the reel longitudinally, the flour is made to pass more readily through the bolting-cloth. We use rubber on the heads under the ribs, where they are struck by the knockers, to prevent wear, and to cause a greater vibration. D represents a small spring on the inside of the chest, against which a. pin er rod, H," strikes to ease its motion as the knoekers strike.

We do not claim any of the parts claimed and described in Letters Patent No. 50,371; but what we claim, is

l. lhc cam-wheels' a t', and spring d, or their equivalents, as arranged in combination with a holt or reel. which vibrates upon its shaft, substantially as herein specified.

2. The arrangement of the rod H, spring E, lever F, and sleeve Gr, with the reel and its pins, substantially as and for the purpose specified.

In testimony that we claim the foregoing We have hereunto set our hands this 31st day of December, 1866.

JESSE B. RUMSEY.
