' JOHN SHINN AND WM. VHITESIDE, OF PHILADELPHIA, PENNSYLVANIA.

LOOM.

Specification of Letters Patent No. 13,022, dated June 5, 1855.

To all 'whom t may concern: Y

Be it known that we, JOHN SHINN and WILLIAM WHITESIDE, of the consolidated city of Philadelphia, twenty-firstvward, late the borough of Manyunk, State of Pennsylvania, have invented some new and useful'Improvements on Power-Looms; and we do hereby declare that the following is a clear and exact description of the construction and operation of the same, reference being had to the annexed drawings, makinga part of this specication, in which-l Figure 1 is a front view;v Fig. 2 is a birdseye view; Fig. 3 is an end view; Fig. 4 is a section showing the horizontal levers C, C, the vertical'levers J, J, the wires W, W, the hooks A, A, the traveling rods E, E, and guides D, D; Figs. 5 and 6 are enlarged views of the swinging plate K, K; Fig. 7 is an enlarged view of the vibrating staple or a loop m, att-ached to the rod R, R; Fig. S is an enlarged view of the levers L, L; Fig. 9 is an enlarged view of the balanced catch N.

We will now proceed to describe their construction and operation, by referring to the annexed drawings; similar letters of reference indicate corresponding parts.XV

The loom framing can be made in any known style or design in which there is a shaft X,on which is an eccentric grooved cam S, in which groove there is a roller on a stud attached to one end of the lever T, which works `on a,1 stud in the center of the lever T, fastened to the loom framing. From the ends ofthe lever T are connections V, V, which communicate the motion to the levers C, C, to open the warp-shed evenly both ways. At the lifting and depressing ends of the levers C, C, are attached straps 2 2, which pass over the rollers F, F, and connect with the traveling rods E, E, in the loops O, O, and as the shed closes the rods E, E, will bring the hooks a, a, to their proper position to be ready for the next movement of the pattern roller. The pattern roller communicates motion to vertical the backward motion of the lay; and as the lay goes back the plates K K will come in contact with the cams on the levers L L, and depress them at that end, and cause the other end to rise, which is connected to the picking staifspulleys by means of straps, and gives motion to the pickers in the usual manner. Also providing the rod G' in front of the reed, and made to vibrate on arms,which are attached to studs or pins fastened on the back of the lay in such a manner that the rod will rise and fall freely'in front of the reed. The rod Gr is connected to the rod I, which is an ordinary protecting rod with the protecting finger H on it by means of the connections y y. On the rod I is a finger e e, under which is a cam 0 c attached to the loom frame; as the lay goes back the linger e e on the rod Gr comes in contact with the cam o c, causing the rods I and Gr to rise for the shuttle to pass under the rod G, and should the shuttle fail to enter the box, it will arrest the downward motion of the rod Gr, and cause the linger H, on the rod I to strike the lever P on the breast A, which will shift the driving strap, and immediately arrest the further advance of the lay, and prevent any injury to the warp threads. Also providing the loom with the staple or loop M (Fig. 7 attached to the rod r r, and placed on the front of the lay near the mouth of the shuttle box, and operated by the swell N; as the shuttle enters the box it presses out the swell N, and the staple falls across the race of the lay, and if there be no weft thread across the opening in the race of the lay the staple M will fall through the opening, and strike the balanced catch U (Fig. 9), which is placed a little below the race, so as to let the shuttle pass over it. If the thread is broken or the bobbin is exhausted the staple M will press the catch under the arm on the rod at the connection T, and cause the finger H to strike the lever P, and stop the loom as before described. W'e do not claim the controlling of the whole series of harness or a part of them, by one lever at the top of-the loom and a 1iumber of levers at the. bottom of the loom;

What we do claim as our improvement,

and desire the same secured to us accordingly, is-

1. The combination and arrangement of one lever at the bottom of the loom, with one at the top, in such a manner as to control any number of levers of harness that may be desirable, and open the warp-shed evenly both ways, as described.

2. We also claim the combination of the guides, traveling rods, the rollers F, F, and straps connecting the lever C, C, for the purpose of bringing the hooks to their proper place in time to be ready for the neXt movement of the pattern roller, as described.

3. We do not claim the vertical levers for the purpose of opening the warp shed-but we do claim them in combination with the wires IV, W, for the purpose of actuating the hooks, as described.

4. We do not claim the swinging plates K, K, but we do claim the combination of the swinging plates K, K, with Vthe levers, L, L, or the equivalent arrangement of the same for the purpose of actuating the pickers as described.

5. We claim the rod, Gr, or its equivalent, so arranged with the rod, I, that when the shuttle is arrested in front of the reed, it will cause the protecting finger H, to strike the lever P, and shift the driving strap and immediately arrest the further advance of the lay, as described.

6. The following we claim as an improvement on the machine of E. Burt, dated June 20th, 1845, in which the said E. Burt claims the hanging weft protector on the race of the lay itself: The hanging of the loop on the race we do not claim, but that which we claim as our improvement and desire the same secured to us accordingly, the balance catch U, in combination with the loop M, and operated by the swell N, so that when the weft thread is broken or exhausted it will immediately arrest the motion of the loom in the first forward motion of the lay as described.
