Specification forming part of Letters Patent No. 103,61 dated May 31, 187

Loom-Tom )lGS of which the followin is a specification Nature and. Objects of the Invent-ion.

The first part of my invention relates to inclined surfaces on the stem of the temple, which, comingin contact with corresponding inclined surfaces on the supports of the temple, will bring the roller always parallel with the race-board of the loom.

The second part of this invention relates to improvements in the construction of the head of the temple, having for its objectthe' ability to adjustand vary. the distance between the. lower edge of the roller and the trough for the purpose of allowing diiferent thicknesses of goods to pass through. his accomplished in three different ways first, by fastening the stem of the temple, cover, and spindle of the roller rigidly together, and adjusting the trough alone; second, by connecting the stem, cover,

and trough rigidly, and making the spindle of the roller alone adjustable and, thirdly, by fastening the trough and stem together, and making both the cover and roller adjustable. -The third part of my invention relates to improved appliances for producing and contro ling the movement of the temple, one consisting-of. a link, one endof which is jointed to the temple-support, and the other to the stem oi the temple. The other appliance, a

1)roperly-shaped too, is fastened tothe lay of the loom, and is intended to press the temple gently outward as the lay moves forward to beat up the weft. The same objectis-aecomplished by causing the lay .to push the temple during its forward stroke against astationary inclined plane.

The fourth part of my invention relates to a provision made to guard against breakage in case the shuttle remains in the shed, by providing the link mentioned heretofore with aslot, so as to allow the stem of the temple to recede farther than is necessary in ordinary cases.

Oonstructima and Operation.

(1-, Figs. 3 and S, is the frame of the temple, which, by means of screws passing through the slots 1) b, is fastened to thebreast-beam of the loom. l

A lug, 0, projects from said frame a, for the purpose of supporting the sliding stem (1. Thisstem slides through an ear, 0, on the frame a, and is furnished with an incline, j, which, when the temple is pushed forward, meets a corresponding inclined suri'acc in thein-terior of the lug-or ear 0, and thus brings the axis of the roller 9 of the temple always parallel with the race-board of thelay. The sameobject is accomplished by the inclined jaw h meeting the lug 0 when the temple terminates its forward stroke. That end of the stem of the temple which extends toward the lay of the loom carries on its extremity the rollerg, with its trough c and cover].

In onler to allow different thicknesses of cloth to passibetween thorol'ler gfand trough 1', the relative distance between the twomay be made variable by making either the roller. and cover, the roller alone, or the trough alone, adjustable,

In Figs. 1, 2, and 3 the roller and cover,

in Fig. 4 the roller, are made adjustable. In

the arrangement shown in Figs. 1, 2, and 3 the trough is cast in one piece with the stem (1, or permanently fastened thereto by well-known means, and the cover and roller, after being properly set, are fastened and held by screws y and z, or either alone.

In Fig. 4, both the trough and cover are cast 1n one piece or fastened together, and thespindle L of the roller 9 is made adjustable in a vertical direction between the trough and cover, the plate It being for that purpose provided with a slot, k, and the spindle i, so that the spindle I may be fastened rigidly anywhere within the limits of the slot k! by means of the nut m when the proper position of the roller has been found.

kon the trough i, Fig. 7, and to allow the nut n to be screwed on the outside to hold'the flange k, Fig. 7, against the flange k, Fig. 6. The slot in the flange k allows the trough a, Fig. 7, to be moved toward or from the roller g, which is intended to run underneath the coverj, Fig. 5.

In Fig. (i, the trough may be adjusted by loosening the screw 00, allowing the trough to swing around it as a center, as shown by dotted lines, and, when the trough is in proper position, to fasten it again.

The motion of the temple is produced byan inclined plane, 1:, fastened to the front side of the lay by means of screws a passing through slots 0. This inclined plane presses against the lug p, which is fastened to the stem 11 by serews'd, or is cast on it, as in Fig. 5.

As the lay moves forward to beat up the weft,and the incline a pushes against the side of the lug p, the cloth is gently stretched until the lay itself strikes the lug squarely, and, in conjunction with the link q, brings the threads of the warp exactly opposite their respective spaces in the reed of the loom.

The link 9 oscillates around the screw 1' as a center, and is connected to the stem (1 by another screw, 1-, passing through the slot 8.-

Itwillbe seen that the link q controls the motion of the temple in such a manner that, when the temple is pushed sidewise by a and forward by the lay, the head of the temple, consisting of the roller g, cover j, and trough 5, moves in a. curved line, dependent on the are 10 10, which the link q describes, and of which'the distance between the screws 1 r is the radius, as shown by dotted lines in Fig.3. As soon as the lay recedes and leaves the lug 17,1118 headof the temple describes the curved line 20 w in a reverse direction, by reason of the contraction of the cloth and the guidance of the link q.

Should it happen that the shuttle remains in the shed,"and is forced against the temple by the lay while beating up, it is necessary to have a further backward motion from auto (1 of the stem (1, to avoid a breakage. Such further motion would be impossible if the screw 1" was made to pass through a round neatly-fittin g hole; but by elongating or slotting the hole, as at s, Fig. 3, the object is attained.

I do not claim as my invention the stem (1,

incline f, roller 9, cover j, nor trough '1 in the abstract, nor do I claim V-shaped projections on the stem d entering into V-sha-pcd recesses on the frame a but What I claim as my invention is- 1. The combination of the inclined surface f on the stem d with the corresponding surface in the interior of the lug or car 0, or their equivalents, substantially as and for the purpose herein specified.

2. The arrangement or the roller g, cover j, trough 1', slot k, elongated shank Z, substantially as and for the purpose herein set forth. 3. The combination of the trough i and cover j, cast together in one piece, or otherwise fastened with an adjustable stud, l, substantially as and for the purpose herein spcciiied.

4. The combination of cover j and stem (1, cast together in one piece or otherwise fastened together, with an adjustable trough, i, substantially as and for the purpose herein set forth.

5. In combination with the inclined projection 11., attached to the lay, as described, the the stem of the temple, provided with the lug p, when operating together, as described.

6. The link q, provided with the oblong aperturc s, and pivoted to the frame a by the screw k, when combined with the stem d of the temple, for the pu'rpose of regulating its lateral movement, by means of the screw r, as described.

In testimony whereof I have afiixcd my hand this 10th day of December, 1869, in presence of two subscribing witnesses.
