SPECIFICATION forming part of Letters Patent N 0. 784,930, dated March 14, 1905. Application filed January '7, 1905. Serial No. 239,994.

To (1.11 70710172, it natty concern.-

Be it known that I, \VILLIAM F. DRAPER, a citizen of the United States, and a resident of H opedale, county of WVoreester, State of Mas-' sachusetts, have invented an Improvement in Loom-Temples, of which the following description, in connection with the accompanying drawings, is-a specification, like characters on the drawings representing like parts.

To those skilled in the art of weaving it is well known that on the beat up of the lay the reed acts through the warp-threads to laterally stretch the cloth adjacent the fell and notwithstanding the employment of the usual temples the cloth has a very decided tendency to contract as the lay recedes. Such wideni ng and narrowing cause the reed-dents to rub and wear the warps, more particularly those nearer the selvages of the cloth. It has been proposed to use laterally-movable temples, the entire temple, with the roll, being moved sidewise to stretch the cloth as the lay beats up, the temple and roll moving back again as the lay recedes. Such an arrangement, however, aside from certain practical objections imparts an intermittent stretch to the cloth with alternating give or slackening, as will be manifest. Greatly-improved results can be secured if the cloth beheld out or stretched allot the time, and my present invention has for its object means to effect this desired result.

In accordance with my invention I have provided means carried by or on the temple to engage the cloth at or near its selvage and to stretch or pull out the cloth laterally as the lay recedes, said means being automatically moved inward to take a fresh hold on the cloth as the lay beats up, the temple-roll at such time keeping the cloth stretched. By such means the widening or stretching of the cloth due to the beat up is maintained as the lay is retracted, so that the warps are brought more nearly into parallelism with the paths of the reed-dents and so maintained, and hence wear on the warps is very materially decreased and warp breakage due to such wear reduced.

The various novel features of the invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a top or plan view of a templehead with one embodiment of the present invention applied thereto, the lay being in retracted position. Fig. 2 is a front elevation of the apparatus shown in Fig. 1. Fig. 3 is a view similar to Fig. 1, but showing the cloth-stretching means in the position resulting from beat up of the lay ready to take a fresh grip or hold on the cloth. Fig. 4 is a front elevation of the apparatus with the relative position of the parts shown in Fig. 3. Fig. 5 is an inner end elevation of the temple and cloth gripping and stretching means and showing in section a portion of the lay; and Fig. 6 is a sectional detail on the line 6 6, Fig. 5, of the gripping-jaws of. the clothstretching means.

The temple-head, comprising a pod B, cap B the toothed roll B, between them and turning on pivots carried by the cap, the heel B secured to or forming a part of the pod, and

the shank B, adapted to be yieldingly mounted in the temple-stand, (not shown,) maybe and are all substantially of well-known or usual construction, the temple herein shown being of the thread-cutting type, such as forms the subject-matter of United States Patent No. 585,465. So far as the present invention is concerned, however, it is not restricted to use with a thread-cutting temple,and as the threadcutting mechanism is of ivellknown construction and operation and in no way effects the present invention it requires no further reference herein. Behind the cap the pod is shown as provided with an elongated upright fixed stud 1, on which is pivotally mounted the hub 2 of a jaw-carrier, shown as havinga lateral extension 3 at the base of the hub, terminating in a depending heel 4:, and at its upper end the hub has an arm 5 overhanging the cap B and terminating in an enlarged depending end 6. A cotter-pin 7 or other suitable retaining device retains the hub of the jaw-carrier on the stud 1.

A sleeve-like housing 8 on the cap B has mounted therein a plunger 9, acted upon by a spring a (see Fig. 1,) the spring being coiled about the plunger between its head 10 and the reduced opposite end 11 of the housing, the plunger bearing against the sideof the arm 5 and tending to maintain the carrier in the position shown in Figs. 1 and 2. A shoulder or stop 7/ on the cap in the path of the head 6 limits such spring-imluced movement of the jaw-carrier, the heel 4 being normally held somewhat in advance of the heel B of the pod, as in Fig. 5, to be first struck by the lay A" when the latter heats up.

The l ad 6 is cut away at its frontand rear faces at 12, Figs. 2, 4, and 5, and laterally recessed or notched at 13 to leave a lixed or rigidly-conneeted jaw 14, the end of the same being preferably rounded otl, as at 15, Figs. 4 and 6. A relatively movable jaw 16 is slotted to present upturned cars 17, which enter the cut-away faces 12 of the head, and said ears are fulerumed on the head by a pivot-pin 18, both the jaw 16 and the top of the recess 13 being recessed (see Fig. 6) to receive the' ends of a spring s', the latter acting to press the toothed face 19 of the jaw 16 toward the jaw 14. eferring to Figs. 2, 4, and 6, itwill be seen that the cars 17 are inclined with relation to the toothed jaw-face 19, so that while movement of the jaw 16 to compress the spring s will separate the two jaws opposite movement will tend to bring them closely together.

.In the operation of the device the selvage of the cloth is inserted between the jaws, the inward transverse pull of the cloth acting upon the jaw 16 to cramp it upon the opposite jaw 14, firmly gri 'iping the cloth. On the beat up the lay strikes the heel 4 of the carrier just about theinstant the lilling is beaten in and swings the carrier on its fulcrum-stud 1 into the position shown in Figs. 3 and 4, compressing the spring .s and causing the jaws to momentarily loosen their grip upon and move nearer the center of the cloth. As the lay beats back the cloth tends to contract as the reed recedes; but the jaws 14 and 16 are then gripping the cloth and moving back from the position shown in Figs. 3 and 4 to that shown in Figs. 1 and 2 under the influence of the spring x the result being that the gripped cloth is pulled out laterally and kept stretched. It will be seen from the foregoing that at the time the jaws release the cloth and move inward to take a fresh grip, due to the engagement of the lay with the heel 4 of the jaw-carrier, the cloth is held out or stretched laterally by the action of the reed and that as soon as the reed tends to release the cloth the gripping-jaws act to retain it in such stretched condition. Consequently the warps, particularly those nearer the selvages, are maintained substantially in parallelism with thepaths ofmovement of the reeddents, and wear on the warps is reduced to a minimum.

The teeth 19 of the movable jaw 16 serve to give the latter a lirm hold on the cloth, while the jaw 14 readily slides under the cloth on the inward stroke of the jaws by reason of the rounded end 15.

My invention is not restricted to the precise construction and arrangement herein shown and described, as the same may be modified or changed in various particularsby those skilled in the art without departing from the spirit and scope of this invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. A tei'nple-head provided with a toothed roll, and separate means located adjacent said roll to engage and laterally stretch the cloth.

2. A temple-head provided with a toothed roll, and separate spring-controlled means to engage the cloth in front of the roll and subject the cloth to a yielding transverse pull.

3. A temple-head provided with a rotatable cloth-engaging member,cloth-grippin g means mounted adjacent said member and movable transversely of the cloth, and a spring-actuated device to govern said means and cause the same to exert yielding side pull on the cloth.

4. A temple-head provided with a rotatable cloth-engaging member, and separate cloth- Ql1]')]')l11g means movable longitudinally of said member, to engage and exert a side pull on the cloth on the backward beat of the lay 5. A temple-head provided with a rotatable cloth-engaging member, a pivotally-mounted jaw-carrier having a fixed jaw, a relatively movable jaw on said carrier, the jaws being bodily movable transversely of the cloth, to engage the same, and aspring to effect retractive movement of the jaw-carrier, and thereby exert a side pull on the cloth engaged by the jaws.

6. A temple-head provided with a toothed roll, a jaw-carrier fulcrumed on the head and having a rigid jaw, a spring-controlled, cooperating jaw, a heel on the jaw-carrier, adapted to be engaged by the lay on its forward beat to move the jaws inward from the selvage of the cloth, and a spring to move the jaw-carrier outward on the backward beat of the lay and thereby laterally stretch the cloth gripped by the jaws.

7. A temple-head provided With a toothed roll, cloth-gripping jaws, means adapted to be operated on the forward beat of the lay to move the jaws inward from the selvage to mementarily release and take a fresh hold on the cloth, and spring-operated means to move the jaws outward as the lay recedes and thereby exert a yielding outward pull on the cloth to maintain the same stretched.

8. A temple-head comprising a pod and a cap, a toothed roll carried thereby, a jaw-carrier fulcrumed on the pod and overhanging the front of the cap, a depending heel connected with the carrier and adapted to be struck by the lay, to rock the carrier, automatically-acting clothgripping jaws on the IIC carrier, rocking thereof by the lay as it beats up moving the jaws inward from the selvage, to take a fresh hold on the cloth, and a spring to oppositely rock the carrier and through the jaws exert a side pull on the cloth.

9. A temple-head provided with a rotatable cloth-engaging member, and separate means to engage the cloth near its selvage and alternately release, and grip and pull laterally the cloth as the lay beats up and retires, respectively.

10. Atemple-head provided with arotatable cloth-engaging member, separate means to engage and exert a yielding lateral pull on the cloth, and a spring to control said means, the latter being adapted to slacken its hold on the cloth on the beat up of the lay.

11. A temple-head provided with a rotatable cloth-engaging member, automatically-acting grippingjaws movable transversely to and adapted to,engage the cloth near its selvage, a jaw-carrier fulcrumed on the head and having a foot adapted to be engaged by the lay to move the jaws inward on the beat up, and

spring-actuated means to oppositely move the carrier and through the jaws exert a side pull on the cloth as the lay recedes.

12. A temple-head provided with atoothed roll, and means to engage intermittingly and stretch the cloth laterally over the roll, the roll by its engagement with the cloth serving to maintain it in stretched position while said means are intermittingly inoperative.

18. A temple-head provided with a toothed roll, and .separate gripping means movable in the direction of the length of the roll, to intermittingly grip the cloth and stretch it laterally, the roll holding the cloth in such stretched position during the periods in which the said gripping means are inoperative.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
