CLOTH-CLAMP FOR TEXTILE MACHINERY.

SPECIFICATION forming part of Letters Patent No. 779,133, dated January 3, 1905.

Application filed February 10, 1904. Serial No. 192,902.

To L7/, whom, it may concern,.-

Beit known that I, HOWARD L. QUICK, a citizen of the United States of America, and a resident of the borough of Brooklyn, city of New York,county of Kings, and State o'f New York, have invented certain new and useful Improvements in Cloth-Clamps for Textile Machinery, ofv which the following isa specification.

This invention relates to a clamp for use with the tenter-frames of 'textile machinery, the object being 'to enable the action of the clamp to take place at the proper moment and prevent the edge of the cloth from becoming disarranged while being manipulated; and the invention consists, essentially, in the construction, combination, and arrangement of parts, substantially as will be hereinafter described and claimed.

In the annexed drawings, illustrating my invention, Figure 1 is a side elevation of my improved clamping device, the clamp/being in the position that it occupies when thrown wide open. Fig. 2 is a similar side elevation of the clamp embodying my invention when in the position which it occupies when in the act of clamping the cloth. Fig. 3 is a top plan view. Fig. 4 is an enlarged'detail View showing particularly the finger which controls or regulates the time when the vclamp acts upon the cloth. Fig. 5 is a similar enlarged and detail View showing the position of the finger 'for controlling or regulating the action of the clamp at the time when both the round portion and the curved edge of the finger are resting upon the cloth.

Similar characters of reference designate` corresponding parts .throughout the different figures of the drawings.

1 designates a link of a chain of any suitable construction. the same constituting a part of the conveying' device with which the tentering-machine is provided. This link 1 is formed integral with a frame 2, which is provided with a bed or table 3, having thereon a face or plate 4, which is preferably of brass to avoid rust, which would be objectionable on account of being injurious to the fabric. The table 3 4 is slotted at 14 (see Fig. 4) to allow the pivoted finger to play up and down through it for a purpose to be presently explained.

In the frame 2 is pivoted at 6 the clampingplate 5, whose edge is movable up and down away from and toward the bed or table 4, and this clamping-plate 5 is provided with an upward extension 7 operable by a suitable cam, as may be customary, and also with a rearwardly-extending arm 8.` To the lower end of the arm 8 is pivoted, by means of the horizontal pivot-pin 9, a movable finger 10, which plays freely through the slot 14 as well as being movable above said slot when carried up and down by the arm 8. The finger 10 is fashionedwith the rounded end 11, the intermediate curved edge 12, and the terminal projection 13. The curved edge 12, as well as the projection 13, Vdrops at times through the slot 14; but the round end 11 rests on the plate 4 whenever the clamp is down. Thus it will be understood that when the cloth is on the table the finger 10 will rest thereon, and during a certain time in the travel of the cloth the round portion of finger 10 and the curved edge 12 will both rest on the cloth, and when they so rest the arm 8 will be held in such a position that the gripping edge of the clamp 5 will be above the cloth and not in contact with the latter. (See Fig. 5.) As the cloth travels onward it will be released from the round part 11, which will drop upon the plate 4; but so long as the curved edge 12 rests upon the cloth said curved edge will not drop into the slot 14, and the clamp consequently will not drop down upon the cloth. 1n order that the period during which the clamp is inoperative may be prolonged until the edge of the cloth has reached the clamp and that there may be no disarrangement of the cloth and no buckling or gathering up of the latter, the projection 13, already mentioned, is provided to rest upon the cloth for a time after it has been released fromvthe curved edge 12, and this projection 13 projects into very close proximity to the gripping edge of clamp 5. When the cloth is released from the projection 13, its edge will be directly under the clamp 5 and the latter will drop thereon and tightly clamp it to the plate 4.

The pivot-pin 9 projects at both sides of the finger 10 and the -ends enter loosely the large circular openings in the parallel side bars 16 of a spring-provided frame 15, they object of which frame is to normally rest upon and exert an evening pressure on the cloth. This frame 15 may be said to consist of the parallel side pieces 16, that are connected together by a cross-piece 19 and are pivoted at the end by means of a pivot 17. Around the pivot 17 is wound a spring 18, which is fastened to a pin 3() on frame 2, while the ends of this spring bear upon the cross-piece 19. Thus the spring has the customary effect of holding the frame 15 down upon the cloth. When, however, the clamp 5 is thrown wide open, and in consequence the arm 8 is lifted, the projecting ends of the pivot 9, which play loosely in the openings 20, will lift the frame 15, as shown in Fig. 1, above the plate 4, so that the cloth may be introduced beneath it. In order to give the bottom edges of the sides -16 a better purchase on the cloth, they are provided with one or more serrationsfnotches, or teeth 21.

The operation of-my improved clamp for textile machinery will be evident from the foregoing description of the operation and arrangement. When the clamp 5 is lifted, and simultaneously the finger 1() and the frame 15 are also lifted rearwardly and upwardly, so that a clear space is left below them between them and the plate 4, the cloth may be inserted. When the cloth is so inserted, the movable clamp 5 is permitted to fall, and likewise the frame 15 and finger 10 will .also fall and rest on the cloth. rlhe clamp 5 is provided with vertical slots 24 to permit the ends of the frame sides 16 to have a free movement in lifting at the time the clamp 5 is lifted. The finger 10 by resting on the cloth holds the clamp 5 away from the cloth until the projection 13 is released, at which time the clamp 5 descends and grips the cloth close to its selvage.

Very many changes in the construction and embodiment of the parts of the invention may be made without varying from the intent and spirit of the same, and I therefore reserve the liberty of departing from the precise details herein set forth.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a cloth-clamp for textile machinery, the combination with a frame having a bed or table, of a pivoted clamp, a freely-movable finger pivoted to the rear of the clamp and adapted to work within a slot of the table, said finger having a rear rounded end that rests when in operative position on the table, an intermediate downwardly-curved portion and a forwardly-extending narrow projection.

2. In a cloth-clamp for textile machinery, the combination with a frame having a bed or clamp provided with aslot, of a pivoted clamp, a finger pivoted to the rear of said clamp, its pivot-pin projecting at both sides, and a springactuated frame adapted to rest on the cloth, said frame being engaged by the projecting ends of the aforesaid pivot.

3. The combination of a frame having a slotted table on which the cloth rests, a clamp pivoted to the frame, a finger pivoted to the rear of the clamp and having a forwardly-extending projection, a frame having edges that rest on the cloth at both sides of the finger, said frame being provided with a spring for holding it normally upon the cloth.

4. The combination of a frame having 'a slotted table on which the cloth rests, a clamp pivoted to the frame, a finger pivoted to the rear of the clamp, and devices on opposite sides of the finger which rest on the cloth at a short distance from said finger so that additional pressure may be exerted to prevent disarrangement of the cloth.

5. The combination of a main fratrie, a pivl January, 1904.
