To @ZZ whom t may concern:

Beit known that we, WALLACE I. STIMP- soN and EDWARD S. STIMPsoN, of Hopedale, in the county of lorcester and Gommonwealth of Massachusetts, have invented an Improvement in Loom-Temples, of which the following description, in connection with the accompanying drawings, is a speciiication, like letters on the drawings representing like parts. Y

In the use of temple-rolls with different kinds of cloth much difficulty has been eX- perienced in the marks which are left by the teeth of the rolls on thin iine goods, and with heavy closely-woven cloth the rolls fail to take proper hold, particularly at the selvages, which latter curl up, and cloth with straight selvages cannot be made.

This invention has for its object the production of a temple-roll which will overcome the before-named objections, the wear on the journals of the temple-roll being also decreased by our invention.

Figure l is a vertical longitudinal sectional view of a temple-roll embodying our invention, the pod and cap being shown in section. Fig. 2 is a side elevation of the temple-roll to more clearly show the arrangement of the teeth. Fig. 3 is a transverse section taken on the line o; er, Fig. l, looking to the right. Fig. 4 is an enlarged inner side perspective view of the dust-protector for the roll-journal, and Fig. 5 is a rear-end elevation of the pod and cap with a portion of the supporting-shan-k.

Referring to Figs. 1 and 5, the inner end of the pod a, forming a part of the shank a', is transversely slotted at a2 to receive a locking-ear b formed on the cap b, the latter in this instance supporting the temple-roll. A lug h2 on the cap (see Fig. 5) rests on the enlarged end a3 of the shank when the cap is in operative position, a bolt bx passing through the lug and into a threaded hole in the end a3 retaining the cap rigidly in place. The inner end of the cap is downturned at d4, and threaded to receive and support one of the pivots or stud-bearings c of the templeroll CZ, a similar pivot or bearing c being held in the outer end of the cap, as clearly shown` in Fig. l.

We have herein shown the temple-roll as provided with bushings d10, axially bored at the ends to receive and freely turn upon the smooth inner ends of the studbearings c c', the end of one bushing projecting beyond the end of the roll, as at dx.

It is found in practice that lint, dust, dto., are apt to collect about the inner end bearing of the usual temple-roll, and we have obviated this by extending the bushing, as at dx, and insertin g it loosely in the counterbore e of a protector e. (Shown separatelyin Fig. 4.) This protector is preferably made of brass or other suitable metal, with laterally-extended wings e?, which enter between the edges of the cap and pod, holding it in place, the bearing or pivot c passing through a hole e3 in the protector, the latter also taking up the end-thrust of the temple-roll when in use. By this means the necessary longitudinal play of the roll is permitted while eifectually protecting the bearing from the entrance of lint or dirt.

In weaving heavy closely-woven cloth it is found that if the teeth of the roll are reduced in number at the outer end of the roll, as at d', Fig. 2, they take a much better hold of the cloth along the selvage, and slack selvages can then be held properly, thus preventing the curling up of the selvage.

lith the usual temple roll, having the teeth disposed equally from end to end, the teeth cannot properly enter and take hold of slack selvages, and cloth with straight selvages cannot be woven. We also prefer to make the teeth at the outer or selvage end of the roll of uniform height, the teeth gradually decreasing in height from about the point d2, Figs. 1 and 2, to the inner end of the roll. This prevents the teeth at the inner end of the roll from taking the greatest hold of the cloth and marking it, for the gradually-decreasing height of the teeth toward the inner end of the roll causes them to take a gradually-diminishing hold on the cloth inward from the selvage.

When weaving thin fine goods, the arrangement of the teeth as to number is reversedthat is to say, the teeth are set closer together at the selvage end, so that a greater number engage the cloth at any one time, and being set closer together they cannot enter so decpl y IOO into the material, thus avoiding marking. Furthermore, the fclose setting :of theiteeth enables them to let go of the fabric more easily as the cloth is moved along.

The arrangement of the teeth as to height is, however, the same as heretofore,-the teeth decreasing in height from the vicinity of "themiddle of the roll to the'inner'end, as de- V'surface of .the roll,the2teeth -graduallydecreasing in height therefroin'towa-rdfthe Iend. of fthe roll, the number vfof teeth beingin- 'creasedtoward one: end of the roll, substanrti'ally as described.
