IMPROVEMENT IN SELF-ACTING TEMPLES FOR LOOMS.

Specication forming part of Letters Patent No. 1,080, dated February 18, 1839; antedated November 6, 18?(8,

To all whom z5 may concern:

Be it known that I, KENDALL GIBBs, of South Berwick, in the county of York and State of Maine, have inventeda new and useful Improvement on Self-Adjusting Temples for Power or Hand Looms; and I do hereby declare that the following is a Jfull and exact description.

The nature of myinvention consists in constructing the temples with a joint, so that if the shuttle stops between the temple and the reed the temple will be pressed back by the shuttle as the lathe strikes against the cloth, without injury to the shuttle, temple, or reed. This joint also allows the temple to vibrate toward the reed as it opens, and after it shuts, as the lathe leaves it, itvibrates from the reed with a reacting motion, which makes the sel- Vage, or threads at and near the edge, tightto any degree that the operator may require, thereby facilitating the entrance and exit of the shuttle.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

It is represented in the three accompanying drawings, of which No. l is a perspective drawing, referred to in this specification by letters. No. 2 is adrawing of aside View, and No. 3 is a drawing of a top view. The two last-named drawings are referred to in this specification by figures, and the parts that are shown in both are marked or referred to in each drawing by the same gure, and the parts that are shown only in one are marked in that drawing only.

A and l (of the accompanying' drawings) is a metal stand, one part of which is at right angles to the other. The upright part has two grooves or slots B B for the bolts that fasten it to the breast-beam ot' the loom, so as to raise or lower it. The lower part of the stand projects out from the breast-beam and has a groove or slot through itlengthwise, (see Fig. 2,) through which the bolt O and 3 passes to hold the slide D and 4, which has a slot in it at right angles to that in the stand, so that the operator can set the temple near or far from the breast-beam in toward the cloth or out from it.4 The slide D and 4 has two projections upon the end, as E E and 5 5, which have the pin F and (5 passing through them and the lower end of the main part of the temple G and 7, which forms the joint, upon which it vibrates easily. The main part of the temple G and 7 has a crooked arm projecting from it, as at H and S. This arm has -a straight projection from it, as at I and 9,

which forms the upper jaw of the temple. The upright portion of the main part G and 7 has al perpendicular groove through its whole length, from one side of which the crooked arm II and 8 projects. There is an angular lever K and 10 fastened in this perpendicular groove by a pin L and ll, upon which it moves easily. The arm M and 120i' this angular lever has a piece across the end N N and 13,13, which forms the lower jaw of the temple. This lower jaw has teeth in it, so as to hold the cloth firmly. The arm O and 14E (which is in the perpendicular groove) has a projection vupon the lower end IJ and l5, against which the head of the screw (that is screwed into the race-board of the lathe ot the loom) strikes to open the jaws of the temple when t-he lathe strikes against the cloth. The jaws are shut by the spring 10, the upper end of which is riveted or dovetailed into the perpendicular groove behind the angular lever K and l0, and the lower end stands out against the arm O and 14 of the lever K and 10 and shuts the temple firmly. In the Drawing No. 2 the side of the main part Gr and 7 and one side of the slide D and 4 are left off to show the lever K and l0 and the spring 16. The slide D and 4 has a projection on the un-- der side Q and 17, with a hole drilled into it for the spiral spring R and 1S, that acts against the lower end S and 19 of the main part G and l0, and presses it out, throwing the jaws from the reed, which draws the selvage or threads at and near the edge, tight. (In Drawing No. 2 a part of the projection Q and 17 is left oft to show the spiral spring R Iand 18.) As the lathe strikes against the cloth the head of the screw in the race-board hits the projection P and l5, which is below the pin F and 6, and as the spiral spring R and 1S is pressed back with less force than the spring 16 behind the lever K and l0 in the per- 2 Lose pendieular groove it throws the jaws toward the reed until the part S and 19 presses in the spring R and 18 and stops against the projection Q and 17, when the end of the lever P and l5 is pressed back into the groove and opens the jaws for the eloth to be drawn through. As the lathe leaves the temple it removes the pressure from the projection P and 15, and as the spring that shuts the jaws is stiffer than the other the jaws are shut before the spiral spring R and 18 aets to throw the temple from the reed. After the temple is shut, as the lathe leaves the temple the spiral spring ae ts and throws the temple from the reed, Whieh draws the selvage or threads at and near the edge of the web tight. The lastnamed threads being drawn tight makes the harness open the shades of yarn or silk with more certainty and facilitates the entrance and exit of the shuttle, and it' the shuttle stops between the temple and the reed as the lathe strikes up against the cloth, the shuttle strikes the jaws of the temple, and as the temple is hung upon a joint, of which the pin F and 6 is the fulerum, the shuttle, striking against the jaws of the temple, presses or throws them back toward the breast-beam without injury to the shuttle, temple, or reed.

Vhat do claim as my invention, and desire to seeure by Letters Patent, is-

1. The joint that allows the jaws of the temple to vibrate toward the reed before they open and from the reed after they are shut, and further allows the temple to be pressed back by the shuttle when it stops between the temple and the reed Without 'injury to the shuttle, temple, or reed.

2. Making the projection upon the lever that opens the temple on the opposite side of the fulerum or joint from the jaws, so that the jaws are thrown toward the reed before they open and from the reed after they are shut.

3. Making the spring that shuts the temple stiffer than the one that throws the jaws of the temple from the reed, so that the jaws are thrown toward the reed before they open and from the reed after they are shut to draw the selvageer threads at and near the edge tight, the whole being constructed and operating as herein described.

KENDALL GIBBS.
