GEORGE YATES AND ELI CLAYTON, E LANCASTER, PENNSYLVANIA.

LOOM.

Specification of Letters Patent No. 11,100, dated June 13, 1854.

To all whom t may concern.'

\ Be it known that we, GEORGE Yarns and ELI CLAYTON, of Lancaster city, State of Pennsylvania, have invented new and useful Improvements in Power-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, making a part of this specification.

The nature of our invention and improvement is a grooved shuttle having a groove with edge to slide in a corresponding groove with edge formed on the lathe cap, between the reed and lathe cap, which we style the operatives protector.

To enable those skilled in the artto make and useour `invention we will proceed to describe its construction and Operation.

A is the shuttle having `a groove on its upper side corresponding with the groove in the lathe cap B. The shuttle passing to and fro is prevented from flying out by the edge C of the groove in lathe cap B, which edge when the shuttle rises over cross threads or other obstructions, immediately fastens into the groove of the shuttle, and keeps it in its proper course, and thus the edge D of the groove in shuttle, and the edge C of the groove in lathe cap B acting against each other, are perfect securities against accidents, by preventing the shuttle from flying out, andinjuring the Operator, and also in case of any obstruction by a thread of the web breaking, by which the shuttle is made to rise over the cross threads. The great advantage in the simplicity of this invention is, that the operator can immediately take up the warp threads, and repair the broken thread, which is frequently occurring, witho-ut the inconvenience of having iirst to remove, guide rods, or other devices, which are serious obstruct-ions in causing de`- lays in such repair. E, the lathe, and F the grate; Gr, the cloth rest; H, the self acting temple through which the fabric ormuslin passes. It rests in a frame or holder I and operates upon said holder in the V grooves J which clasp the temple H at its sid-es, and allows the temple to slide backward, in case of obseruction and is for the purpose of effectually preventing the breakage of temple, shuttle or reed, when the shuttle might be into the cloth rest G and is to regulate the holderI when weaving a narrow or broader cloth;` L, the spring located in the center of the holder I, underneath the temple H for the purpose of holding the temple in its proper place until forced back by the lathe or other obstruction; M, the supporter of wire lever N which extends downward near to the lower end of grate or reed F. The threads F P are attached to lever Naud pass through the grate F and extend until beyond the junction Q where they unite, and near which junction the weft or filling thread passes between.

Q Q are the knots formed of metallic or fibrous threads, and by being k'notted do not allow the weft thread to pass to the junction, and they give motion to the wire lever Nand assist in instantly stopping the loom in case of the weft or filling thread breaking or running out.

The object of our invention is to prevent the shuttles, reeds, or temples from being broken (which is constantly occurring) .in case of any obstruction or the thread of web is broken.

The advantages of our improvement are numerous and valuable. 1st. By this invention we prevent the shuttle from flying out and injuring the operator, and its importance is so manifest, as it is well known that these accidents hourly occur in cotton mills, by which many of the operatives have been seriously injured in limb, and frequently deprived of their sight, and compelled to quit their work forever. 2d. On the ground of economy and simplicity 2O to 30 per cent. is saved. The numerous devices of levers, rods, springs, brackets and forks, as in other looms are dispensed with, and no time is lost, or delay caused by the shuttle rising over cross threads or other obstructions as the operator can instantly remove, and repair the same; and our invention and improvement of the lathe cap can be attached to all power looms in a whole or in separate pieces.

We are aware of the patent granted to H. T. Robbins on the 14th of September,

1852 for an improvement in shuttle guides the grooved lathe cap as hereinbefore deand looms Which is mainly intended for the scribed and for the purpose set forth.

same purpose as that aimed at'by us.

What We claim as ourinvention and desire to secure by Letters Patent is A mere improvement upon the contriv- Witnesses present: ance of the said Robbins and which consists J. FRANKLIN REIGART, in the grooved shuttle in combination with 4 CI-IAS. F. VoIGT.
