BENJAMIN F. FRAMPTON, OF BUNXATAWNEY, PENNSYLVANIA.

IMPROVEMENT IN CHURN-POWERS.

Specification forming part of Letters Patent No. 117,166, dated July 18, 1871.

To all whom 'it may concern:

Be it known that I, BENJAMIN F. FRAMPTON, of Punxatawney, inthe county of Jefferson and State of Pennsylvania, have invent-ed a new and Improved Power for Ghurns; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing making a part of this specifica-tion, in which- VFigure l is a side elevation; Fig. 2, an end elevation. Fig. 3 is a sectional elevation of the 4shaft Iand drums, and Fig. et is a side elevation of the brake for the Sha-fn.

My invention is an improvement in the class of churn-propellers which includes as a distinguishing feature a weight suspended by a cord from a winding-drum. My invention consists in an arrangement, hereinafter fully described, of parts whereby, as one weight descends, it not only operates the churirdasher, but also raises another lesser weight, which, when the former has reached the floor, is in turn allowed to descend and continue the movements of the dasher.

Referring to the drawing, a is a churn; b, the dasher; c, a walking-beam that works the dash er through the medium of a pitman, d, and is itself' worked by a pitman, c, thatis jointed to a crank, f, formed in a shaft, g, mounted crosswise of a pair of vertical standards, A B, and connected by gearing h 'L' with a second shaft, j, mounted in the same standards. The shaft j bears two drums, k l, one fixed, the other loose. rlhe loose drum Z is provided with a spring-pawl, m, which when pressed inward engages with a circular ratchet, n, secured to the side of a disk, o, that is iiXed on the shaft j. To the periphery of the drum lis attached one end of a cord, p, the same passing thence upward over ashea-ve, q, mounted on a pin that extends from the end of the crossbar r, which connects the upper extremities of the standards A B. When the drum l is turned backward the cord p is wound tightly around the drum and the weight c, which is fastened to the end of said cord, is thereby raised. The cord presses the pawl m inward, but the latter only slips over the ratchet a as long as the drum l is p rotated backward. When the weight c has been raised to the sheave q the backward rotation of the drum l should cease and the weight allowed to descend. Thereupon the pawl m engages with the ratchet n and effectsthe rotation of the shafts g and j and the working of the dasher. The drum 7c turns with the shaft j, and consequently winds 'up the lesser weight s Aby means of the cord t passing over the sheave u. The weight s reaches the sheave u at the same time that the weight c reaches the iloor. The unwinding of the cord p from the drum l allows the pawl m to separate from the ratchet a, and as soon as this takes place the weight s begins to descend and t0 turn the shaft g in the opposite direction. rIhe direction, however, in which said shaft turns is a matter of no consequence, as it works the dasher equally well either way. rlhe weight s continues to operate the dasher till it reaches the floor. By this arrangement the same effect is produced/as though the distance traveled by the weight c were twice what it is. By employing two weights, as described, the frame is as it were balanced and rendered steady without the aid of devices for securing the saine to the floor or other support, and the friction or strain on the drivingshaft is not applied to one end alone so as to cause it to wear unequally. A brake, u, Fig. 4, is hung to one side of the standard B. By means of a screw, a', said brake can be pressed against the rim of the disk o. rlhis is done when turning the drum backward to wind up the weight c, and the object of doingit is to prevent the backward rotation of the shaft j at the same time.

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

The driving-shaft j, liXed drum 7c, loose drum Z, pawl m, ratchet n, gear-wheels h c', pulleys q u, small weight s, and large weight c, arranged in connection with the frame A B 1", as shown and described.
