CLOTH-CLAMP FOR TEXTILE MACHINERY.

SPECIFICATION forming part Of Letters Patent No. 710,799, dated October '7, 1902.

Application filed February 27, 1902. Serial No. 95,898. (No model.)

To all whom it may concern.-

30 it known that I, IRA F. PEOK, a citizen of the United States of America, and a resident of Auburn, in the State of Rhode Island, have invented a new and useful Improvement in Cloth-Clamps for Textile Machinery, of which the following is a specification.

This invention relates to cloth clamps or clips of that classknown automatic clips; and it consists in certain novel combinations of parts, including spring-pressure devices, hereinafter set forth and claimed. The combination in one and the same clamp of the automatic principle and the springpressure principle in various ways is set forth in United States Letters Patent heretofore granted to Robert P. 'Winsor, No. 604,103, dated May 17, 1898; No. 644,543, dated Feb ruary 27, 1900, and No. 667,159, dated January 29,1901. In all the several clamps set forth in said XVinsor patents the spring is applied to the movable jaw, as in the spring-clamps formerly in use and, in common with the lat ter, fails to relieve the clamps from one limitation or difficulty in their adaptation to the different conditions under which they must operate.

The difficulty to whichI refer may be stated as follows: In practice the leading end of the cloth as it enters the tentering-machiue is sewed by a cross-seam to the preceding piece, and this is repeated for successive pieces, so as to have a steady run of cloth into the machine. Now in each clamp the jaws must fit very accurately and be perfectly parallel. They should fit so close as to be almost lightproof, and either end of the clamp should hold the thinnest tissue-paper. The movable jaw is supported above (or beneath) the clothplate in all automatic clamps by an arm or arms, usually two, and the clamp is organized with reference to retaining the movable jaw in effective position; but if a seam, as above referred to, gets into a clamp at either end it is practically certain to spring the arm or arms and cause the two jaws to get out of parallel, which renders the clamp thereafter unfit for nice work. This trouble has been a great source of annoyance to users of automatic clamps.

The leading object of the present invention is to render the clamp yielding at eithcrend, so that itmayaccommodate itself to a seam at any point without injurious strain.

Another object 'is to apply the spring or springs to the cloth-plateinstead of to the arm or arms, and thus to incorporate the advantages of spring-pressu re in'a large class of such clamps to which it has not heretofore been applicable-namely, those in which the arm or arms project rigidly from the tenterchainlink or body of the clamp.

Other objects are to provide for the use of a pair of short spiral springs beneath a looselyhinged cloth-plate as theimproved spring device and in this connection to facilitate adjusting the clamp and regulating the springpressure as to tension.

Three sheets of drawings accompany this specification as part thereof.

Referring to the drawings, Figure l is a sectional plan view of an improved cloth-clamp. Figs. 2 and 3 are end views of the same, the former partly in section, showing the movable jaw and controller in their elevated positions and their lowered or working positions, respectively. Fig. 4 is a front elevation projected from Fig. 3. Fig. 5 is a sectional plan view of anotherim proved clamp. Figs. 6 and 7 are end views thereof, illustrating its operation. Fig. 8 is a front view projected from Fig. 7. Fig. 9 is a top view of another improved clamp. Figs. 10 and 11 are end views thereof, illustrating its operation; and Fig. 12 is a front view projected from Fig. 11.

Like letters and numbers refer to like parts in all the figures.

The main body of the improved clamp in either species conveniently forms a link of a tentering-chain, as is customary, and comprises, preferably, a pair of rigid arms land 2, to the free ends of which the movable upper jaw a of the clamp is pivoted by a horizontal rod 3. The other jaw b is in the form of or comprises the customary cloth-plate, and a controller 0 or c prevents the descent of the movable jaw into eifectiveposition until the selvage isdrawn from beneath the controller, so that the selvage itself may be held between the jaws.

Moreover, in all the spe-' cies a spring-pressure device comprising a spring or springs (Z or d or (Z is so applied as to permit a seam or the like to he accommodated between either end of the movable jaw and the cloth-plate without straining said arms or any other part of the clamp. In all the species, moreover, the movable jaw ct is provided with the usual rigid ing 4, by which to open the clamp to receive the cloth, and a stop device, comprising a stop or stops 5 or 5, limits an appreciable travel of the movable jaw with the cloth,(represented bydotted lines at a in Figs. 3, 7, and 11,) as in said Winsor clamps. In the species represented by Figs. 1, 2, 3, and 4 the hinge-rod 3 forms, in connection with the coacting parts of the

arms

1 and 2 and the movable jaw a, an ordinary hinge, such as is usually employed for the movable jaw of an adjustable clamp. The cloth-plate b is rendered vertically movable by a loose hinge'joint 6, attaching it at its rear edge to said body of the clamp in such manner as to permit either end of the cloth-plate to be raised or lowered relatively to the other end, as well as to permit the cloth-plate as a whole to move on the axis of said hinge-joint, and a pair of the springs d are arranged in sockets 7 beneath the respective ends of the clothplate, being supported beneath by screwplugs 8, Fig. 2. The upward movement of the cloth-plate is limited by stops 9 at its ends, as best seen in Fig. 4. A pair of short spiral springs sufice in this arrangement,and the adjustment of the clamp is very easily effected by regulating the respective springs as to tension by means of the screw-plugs. The controller 0 in this as in any other form of the improved clamp may be of any known or improved construction adapted to permit said travel of the movable jaw a with the cloth. The specific device represented consists of a bar having a pivotal and sliding movement, being hinged to a projection 10 on the back of the movable jaw and sliding back and forth at its rearend on a rod 11, bridging the space between the

arms

1 and 2 parallel with said hinge-rod 3 and occupying a longitudinal slot in the controller. The front end of the controller c rests at first upon the cloth, as in Fig. 2, above the customary slot 12 in the clothplate I), and when the selvage passes it, drops through the slot, as in Fig. 3, and permits the movable jaw ct to bite the cloth. A pair of stops on one or each of the

arms

1 and 2 and on the movable jaw a, respectively, constituting said stop device 5, limits the travel of the movable jaw Ct with the cloth,as aforesaid. Such travel is freely permitted by said slot in the controller 0, and at its limit, when the stops at 5 come together, the cloth is held with the maximum power of the clamp, determined by the strength of the spring d.

In the species represented by Figs. 5, 6, 7, and 8 the movable jaw a and the cloth-plate Z) are hinged as above described with reference to Figs. 1, 2, 3, and at. The controller 0 is of the construction there shown, as before middle and upwardly against the cloth-plate b at its respective extremities, takes the place of the pair of springs in the first species, with their appurtenances. A horizontal rod 14,

held at its ends in those members of the stops 9 that are fast on the body of the clamp, supports the spring (1 in eifective position.

In the species represented by Figs. 9, 10, 11, and 12 the rod 3, that hinges the movable jaw a, is mounted in a pair of boxes 15, slidable vertically in notches in the free ends of the

arms

1 and 2, and two pairs of wire springs d rigidly attached to the sides of the

arms

1 and 2, press downwardly on said boxes as the equivalent of the upwardly-pressing springs in the first and second species. It will be understood that in this arrangement the movable jaw a yields upwardly at either or both ends, and the cloth-plate b is rigidlysupported beneath by the body of the clamp, asin Fig. 10 and 11. A different form of controller 0, which it projects rigidly from the jaw a, is shown in this species, and also a diiferent form of stop device 5, the fixed member of which is supported by a bar 16, conmeeting the

arms

1 and 2 near their free ends, and coacts with the lug 4, by which the movable jaw is operated to open the clamp, as above described.

Other forms and arrangements of the springs and stops, a pair of short pivots taking the place of either of the hinge-rods 3, and other like modifications will suggest themselves to those skilled in the art. I

In the appended claims the term arms will be used to signify one or more arms performing the functions of the

arms

1 and 2.

The term vertically movable is used to distinguish the movability of the hinge-rod 3 or its equivalent and the cloth-plate b from the pivotal movement of the jaw a.
