ARNOLD PALMER, or NEw LEBANON, NEW YORK.

IMPROVEMENT IN WEAVERS TEMPLES.

Specification forming part of Letters Patent No. 4,379, dated February 10, 1840.

.To a/ZZ whom it may concern:

Be it known that I, ARNOLD PALMER, of New Lebanon, in the county of Columbia and State of New York, have invented anew and improved self -acting temple to be adapted to power-looms for weaving cloth of various descriptions; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure l represents a perspective view; Fig. 2, a geometrical side elevation, and Fig. 3 a view of the under side of one of my temples.

The same letters refer to the same parts in all the figures.

a a is a bar of metal, which,being` attached to the breast-beam of the loom by the screws b b, gives support to the working parts of the temple, consisting of the jawsc c o c and the bent lever CZ CZ. Both of the jaws c c c c move freely about the pin e, which passes through holes drilled near their inner ends, and is permanently iixed to the supportingbar a a. The portion ff, Figs. l and 2, of the inner end of the upper jaw is a little chamfered, and, being pressed downward by the heel of the spring g g, Fig. 2, the outer ends of the jaws are caused to open to receive the selvage of the loth. Those portions of the jaws which seize the cloth are roughened or serrated,like the jaws of the common vise, in order to take a stronger hold. To bring the jaws together, so as to pinch the cloth, the spring g g is used. This springhas at its heel two holes drilled in a direction parallel to its length to receive the pins e and h, which are permanently fixed to the supporting-bar ce a, and consequently prevent the spring from having any lateral motion. The compression is produced by causing the inclined top of the upper jaw c c to slide beneath the outer end of the spring g g.

A temple is of course placed at each side of the web, and the supporting-bar ct ci is placed parallel to the selvage. To bring the jaws beneath the spring so that its pressure upon the inclined top of the upper jaw shall produce the requisite pinch, as before mentioned, the bent lever d d is attached to the under side of the supporting-bar d a, having motion about 'the pin i. In the end of the lever immediately under the jaws is a slotj, Figs. l and 3, which embraces a pin 7c, iirmly fixed in the upper jaw and working through a hole in the lower. This pin plays freely in the slot Zin the supporting-bar, which limits Awith the jaws, dto., is brought back to the position represented in the dotted. lines by the pressure of the spring g g upon the inclined top of the upper jaw c c upon the return of the lathe. The spring is represented in Fig. l by dotted lines only to avoid obscuring other parts. The jaws seize the selvage while the lathe is advancing toward the lilling, hold it iirmly at the moment of beating up, and, unclosing, leave the cloth and warp free to vibrate while the shades are changing. A uniform and handsome selvage is thus obtained, and the chafing so injurious to the warp in weaving fine cloth is obviated.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The mode Of combining and arranging the parts composing my self-acting temple, so that the jaws commence closing upon the selvage while the lathe is advancing toward the filling and after rmly holding the cloth at the moment of beating up open and leave it at liberty to vibrate while the shades are changing, the Whole being constructed and operating as herein described and shown.

ARNOLD PALMER.
