TG ALL WHOM IT MAY CONGERN Be it known that we, WILLoUGnBY W. Pnrnmrs and VARNUM '.l. PHILLIPS, of Wellsville, in the county of Allegheny, and State of New York, have invented a new and useful Improvement in Looms; and We do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which- Figure 1 is a top view ofthe loom.

Figure 2 is a sectional view, showing the'parts used to operate the shuttle.

Figure 3 is a sectional View of the loom through the line y y, fig. 1.

Figure 4 is a detached view of the shaft G, figs. 2 and 3; and

Figures 5 and 6 are views ofthe changing beams used for diierent patterns Similar letters indicate like parts in all the gures. p The nature of our invention consists in an arrangement of ratchet-wheels, pawls, and cams to operate the shuttle.

To enable others skilled in the art to mak-e and use our invention, We will proceed to describe its construe tion and operation.

A A is the frame of the loom, to which is pivoted at `O O, (figs. 2 and 3,) the lay L, and to which motion is imparted in any convenient manner. B is the picker-staff, pivoted to the upright piece of the lay at n, iig. 2. D is an arm ofthe picker-stall, containing an elongated slot, e, in which works the bent part b of a rod, m, the other extremity of said rod being also bent at right angles to bear upon a cam, F, on a shaft, G, which has its bearings in the nprights of the lay. S is a spiral spring on the rod m, to force the foot ofthe rod upon the cam F. a is arocl connected to one extremity of the picker-stadi` B, the other end of said rod being attached to the picker C. P P are pawls hinged to the frame, and operating upon the ratehets R R on the shaft G when the lay is in motion. By means ofthe ratchets R R and pawls P P the shaft G is rotated when the lay is in motion, and the cams F F ou said shaft are brought to operate upon the bent ends or feet of the rod m, giving motion to the picker-sta and picker in a backward direction, but when, by the further rotation of this shaft, the cam is removed from under the end of the rod, the spring S throws the rod down and drives the shuttle across the leem.. The bent end b of the rod m enters an elongated slot, e, in the arm D of the picker-stafi`, which. allows the picker to yield somewhat, and thus lessen the concussion consequent upon the meeting of these parts. h L a, iig. 1, are the treadles for operating'the harness in conjunction with the tappets t2 t", situated on the shaft H, which has its bearings in the'frame of the loom. The treadles have openings, r r, in each of them, which permit the immediate upward motion of the harness when the tappets pass into said openings by the rotation of the shaft H. The tappet-shaft H is rotated by means of the pawls K K, pivoted to the uprights of the lay, engaging with the ratchet-wheels I I on the shaft H. A pawl, hinged to the frame of the loom, is also placed at each extremity of the shaft H, gearing into the ratchet-wheels I I, to prevent the backward movement of the shaft H. M N, figs. 5 and 6, are changing beams, in which the tappets are arranged to operate the treadles for ditlerent patterns. These beams are so constructed that when a di'erent pattern is required, a beam, as H, may

be removed andreplace'd by another. N, thejournals of the dilerent beams, fitting accurately the bearings in the frame of the loom. T is the cloth-beam, operated to wind up the cloth by the crank, U, in any convenient manner, and v is a ratchet-wheel, ,and W a pawl, tig. 3, to prevent the backward movement of the clothbeam. X is the yarn-beam, having a ratchet-wheel, f, at one. extremity, in which operates a pawl, g. a is a let-off arm, hinged to one ofthe uprights of the frame, and connected at one end by the rod c with the pawl g, which gears into the ratchetff, to prevent backward motion of the yarn-beam. When it is desired to Wind up the cloth on the cloth-beam, by operating the end of the let-oit` arm next the cloth-beam, the pawl g is drawn away from the ratchetfand the yarn-beam is free to rotate, in order to permit the cloth to be wound upon the cloth-beam. Having thus fully described our invention, whatwe claim as new, and desire to secure by Letters Patent, is We claim the ratchet-wheels R R, and pawls P P, in combination with the cams I" F, bent rod m, spring S, picker-stati` B, rod a, andl picker C, for operating the shuttle, substantially as described.
