MACHINE FOR SECURING STRETCHlNG-BANDS T0 CARD-CLOTHS.
SPECIFICATION formingpart of Letters Patent No. 571,985, dated November 24, 1896.
Application filed August 9, 1895. Serial No. 558,770. (No model.)
To aZZ whom it may concern;
Be it known that I, JACOB STAUBLI, a citizen of Switzerland, residing at Oalw, in Wiirtemberg, Germany, have invented a new and useful Improvement in Machines for Secur in g Stretching-Bands to Card-Cloths, of which the following is a specification.
The present invention consists of a machine by means of which carding-cloths are hemmed with stretching-bands of soft steel in such a manner that the latter passes over the top of the cloth, and a continuous rib of the steel band is pressed into the top of the cloth, and the cloth is further securely held at the bottom by the steel bands by means of dovetails stamped from the steel bands and pressed firmly into the under side of the cloth. After this has been done the cloth is secured to its cover-block by bending the rims of the band about the edges of the cover in a wellknown manner.
In the drawings the machine is shown in Figures 1, 2, and 3 in two vertical sections and plan. Figs. 4 and 5 show,on a larger scale, the special arrangement by means of which the pointed dovetails are stamped out of the soft-steel bands and then pressed into the lower side of the cloths. The other views, Figs. 6 to 8, show, on a still larger scale, the special devices for stamping the dovetails b from the steel bands B and pressing them into the under side of the cloth.
The stretchin g-bands B,which are most conveniently made of soft sheet-steel, are first bent in L shape and are placed about the edges of the cloth A so that their shorter sides lie upon the top and grasp the cloth, and the cloth is then laid upon the adjustable tracks M. These tracks M are adjustable up and down and sidewise by means of the set-screws m and m, respectively, and are secured to opposite supports E. Directly over these guidetracks M there is a revoluble roller D, turning on an axis cl, which is located in a lever L, provided with an adjustable weight Z, the lever being pivoted at d and the two projecting rims of the roller D pressing the steel cover-bands B firmly against the cardingcloth A and the latter against the tracks M.
In the two supports E, which are likewise adjustable to and from each other by means I of the screws 6, there are rotatably supported angle-levers G by means of the pointed screws e On the shorter arms of the angle-levers G 8,) which have on the front side a triangular point-f, corresponding to the form of the piece a b which is to be stamped out. The longer forked arms of the lever G are joined to cranks H by means of longitudinally adjustable turn buckles i and crank-pins 72, the axes of the cranks H being in bearings in a common plate S and the outer ends thereof being provided with spur-wheels R, which are set in equal uniform and opposite motion by means of the spur-wheel r, the transmission-gears r, and belt-pulley U. j
The base-plate S is secured to the two cheek-pieces O, which lie upon the uprights N. The driving-shaft of the driving-pulley U (fixed and loose pulleys) and the spurwheel '1' are located on one side in a bearing on the upright N and on the other in a bearing in a bracket n, which is secured to the upright N. At each revolution of the spurwheels R the crank-disks H also make a revolution, whereby the angle-levers G are moved and, by means of the points f of the dies F, cuta three-cornered piece I) (shown three'cornered in the drawings) from the side walls of the stretching-bands B in such a manner that the base of the triangular piece is left intact with the bands and is bent upward and is pressed with its point firmly into the under side of the carding-cloth A, Figs. 6 and 7. The form of the stamped-out piece I) may be any other desired than triangular. In the drawings it is assumed that at each revolution of the cranks H a piece I) is stamped out on both sides and pressed into the under side of the carding-cloth. There can, however, equally well be two or more pieces stamped out on each side simultaneously, for which it is only necessary to provide a corresponding number of points f upon the dies F. The forward feeding of the carding-cloth is intermittent and always takes place when the points f of the dies F are not engaged with the stretching-bands. The feed motion'is secured as follows: One end of the cover-bands is grasped by a pair of tongs whose shank ends are connected to a chain K by means of diagonal coupling-links, the chain passing over a sprocket-wheel K. This sprocketwheel K is located on a cross-shaft 1v, running in bearings on the cheek-pieces O, and a ratchet-wheel W' is located on the end of the shaft w. A pawl t, located on the slide T, meshes with this ratchet-wheel, as also a second pawl The intermittent feed of the ratchet-wheel \V is produced by the up-and-down movement of the slide T. This is produced by means of a pin t located 011 the slide T, which is lifted a short distance by means of a lever 1;, located on a shaft P, which is oscillated. The shaft P receives its small oscillating movement from a small lever '0, secured to its other end by means of a roller 00, which is lifted by one of the cranks H, the roller 00 being located on a prolongation of the crank-pin 7t. The rising-and-falling movement of the lever '12 continues through only about one-fourth of a revolution of thecrank H, andduring this time also the intermittent forward feed of the carding-cloth takes place. If during each revolution of the crank only one dovetail on each side is to be stamped out, there will be a forward feed to the extent of one dovetail only. If two, three, or more dovetails are to be stamped out on each side simultaneously, the feed will be to the extentof two, three, or more of these divisions b. After the carding-cloth has been hemmed on both sides, top, and bottom in this manner it will be secured to the cover-block rims in a well-known manner by bending the bands B around the cover-block O. The ends of the cloth are, also secured by bands in the manner described above, but they are not secured to the cover-block. The steel bands thus secured to the carding-cloth hold remarkably tight and furnish a very good and durable stretching of the same without injury to the material of the cloth.
IVhat I claim, and desire to secure by Letters Patent, is

4. In a machine for securing stretchingbands to eardin g-cloths, the combination,with mechanism for feeding the carding-cloth and bands longitudinally, of a roller having flanges, and means for pressing the flanges 0f the roller against the bands, substantially as set forth.
5. In a machine for securing stretchingbands to carding-cloths,the combinatiomwith mechanism for feeding the carding-cloth and bands longitudinally, of a lever fulcrumed at a fixed point, and a roller mounted in the lever and provided with flanges arranged to contact with the bands, substantially as set forth.
6. In a machine for securing stretchingbands to carding-cloth, the combination, with mechanism for feeding the carding-cloth and bands longitudinally, of a lever fulcrumed at a fixed point, a roller mounted in the lever and provided with flanges, and means for forcing said flanges into contact with the bands, substantially as set forth.
7. In a machine for securing stretchingbands to carding-cloth, the combination, with mechanism for feeding the carding-cloth and bands lon gitudinally,of a roller provided with flanges, means for forcing said flanges into contact with the bands, a lever mounted at right angles to the direction of travel of the cloth and bands, a die carried by the lever, and means for oscillating the lever to bring the die against and away from the bands, substantially as set forth.
8. In a machine for securing stretchingbands to carding-cloth, the combination, with intermittent feed mechanism for feeding the cloth and bands longitudinally, of anintermittently-actuated die mechanism arranged to act on the band when the feed mechanism is at rest, substantially as set forth.
9. In a machine for securing stretchingbands to carding-cloths,the combinatiomwith a feeding mechanism for feeding the cloth and bands longitudinally, of a pair of dies acting on the bands, and mechanism for intermittently actuating the dies and feeding mechanism, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
