MACHINE FOR MAKING TUFTED FABRICS.

SPECIFICATION forming part of Letters Patent No. 686,738, dated November 19, 1901.

Application filed March 2, 1900. Serial No. 7,048. (No model.)

To all whom, Lt may concern:

Be it known that I, JOHN KASCHENBACH, a citizen of the United States, residing at \Vilkesbarre, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Making Tufted Fabrics, of which the following is a specification.

This invention relates to improvements in the class of rotary tufting-machines of which that illustrated in the United States Patent No. 622,901, granted to O. S. E. Spoerl April 11, 1899, is an example; and the important objects of the invention are to provide against distortion of the machine under heavystrains, to provide an improved button feeding and setting mechanism, and to provide a washerfeeding mechanism.

In the accompanying drawings, which illus trate an embodiment of the invention, Figure 1 is aside elevation of the machine. Fig. 2 is a front or end elevation of the machine as seen from the left in Fig. 1. Fig. 3 is a fragmentary vertical section taken in the plane of the drum-axis at line m in Fig. 1. Fig. 4 is a fragmentary vertical transverse section through the drums at x in Fig. 2, but on a somewhat larger scale than the principal views. tail View of the ratchet mechanism, the sec tion being at line in Fig. 2. Fig. 6 is a fragmentary detail plan view of the buttonfeeding device. Figs. 7, S, and 9 are sectional detail views of the clenching mechanism on a relatively large scale. Figs. 10 and 11 are similar views of another slightly different form of the button-clenching mechanism.

1 is a strong frame of any kind, but preferably of metal, for supporting the mechanism, and 2 is the fixed bed of the machine in said frame. Extending across the space between the sides of the frame 1 and rotatively mounted in the latter are the tufting-drum A and the lower or anvil drum B. These drums are hollow, with large tubular journals 3 and 4, respectively, as best seen in Figs. 3 and 4:, and the drums are geared together by gears 3 and 4. On the driving-shaft 5 in the lower part of the frame are tight and Fig. 5 is a fragmentary sectional de-' loose pulleys 6 and eccentrics 7 7, each of which operates, through a rod 8, a hook-pawl 9, Fig. 5, which engages a ratchet-wheel 10 on the journal of the drum 4. Thus rotation of the shaft 5 imparts intermittent rotative impulses to the drums in the direction of the arrow win Fig. 1.

The tufting-drum A has radial tuftingtubes 11, Fig. 4, arranged in circumferential series. As here shown, there are nine tubes in a series; but this is not important so long as they are properly spaced for tufting. The number of series of these tubes will depend on the length of the drum and the width of the fabric made. Between these tubes, both laterally and circumferentially, the surface of the drum is formed concave, so as to mold the surface of the stuffed fabric.

The drum B is a cylinder and has clenching-anvils 12 in its periphery arranged in series to correspond with the ends of the tufting-tubes 11 as the drums rotate intermittently.

Fig. 1 shows the base fabric 00, the filling material y, the top fabric a, and the completed tufted fabric X as it emerges from the machine.

In order to shape the materials as they enter between the drums, the construction now to be described may be employed. The base fabric a; is drawn over the bed or table 2 and into the bite of the drums, and the filling material is placed thereon as needed. The top or cover fabric is led in from a roll 13 in a frame 14, passing about and between an idler 15 and a roll 16, driven by gears from the drum A. On the table or bed 2 is a shaper for the filling, comprising a frame 17, connected at one end to the main frame at 18. In this frame are rotatively mounted two

rolls

19 and 20, formed as seen in Fig. 2-that is, each has a series of circular disks, which are alined with the respective series of tubes 11 on the drum A, and concave spaces between the respective disks. driven by gearing from one of the drums, and about the two rolls is an endless apron 21, of canvas or other suitable fabric. This apron takes somewhat the shape of the drums 19 The roll 20 is and 20, and the former shapes and molds the filling as it passes to the drums to receive the buttons.

The buttons I), each of which has two prongs 5 p, are fed automatically to the tubes 11 of the tufting-drum by means that will now be described, premising that ordinarily each button has its head covered with plush or some soft material of a similar character.

The inclined button-tracks 22 are situated above the drum A and alined with the respective series of tubes 11. The buttons are supplied by hand'and slide down the track, their prongs projecting upward through a slot in the cover of the track, as seen in Fig. 6. The track ends over a tube 11, and a plunger 23 presses the button down head first into the tube to the proper extent. The plungers 23 are actuated at the proper times by cams 24 on the main shaft 5 through the medium of levers 25, each bearing a roller 26, which rests on a cam 24, and rods 27, which extend up and are coupled to arms 28, fixed to the opposite ends of a rock-shaft 29, which has on it arms 30,to which the respective plungers 23 are 'tures 31, which are bridged by the anvils and which are by preference circular, and the anvils are set in or below the outer surface of the drum B to an extent sufficient to allow room in the recess for a washer 32, of leather, felt, or other suitable penetrable material.

The means for placing the washers in their recesses over the anvils 12 will now be described with-especial reference to Fig. 4.

Supported on the frame of the machine and alined with the several circumferential series of washer recesses 31 are tubular washer magazines or holders 33, each provided with a plunger or follower 34 and spring 35. The spring and follower keep the washers pressed up to the face of the drum B, and when the latter is intermittently rotated it stops with a series of the recesses 31 coincident or in register with the magazine 33, so that a washer is pressed from each magazine into a recess. The rotation of the drum brings these washerfilled recesses to the button receiving and clenching point at the top of the drum. There are now presented at this point a series of buttons b in the tubes 11, situated above the fabric, and washers 32, under the fabric and registering with the tubes 11, each washer overlying an anvil 12. The series of buttons 1) are now driven downward, their prongs 19 passing through the fabrics z and a; and

through the washers 32, this being effected by ated by rods 39, coupled at their lower ends to crank-pins 40 on the cams 24.

Simultaneously with the driving down of the buttons through the fabric and the spreading of their prongs on the anvils in the drum B clenching devices for said prongs are operated upward by mechanism now to be described.

Aclenching-bar 41 extends through the hollow or tubular journals of the drum B and plays in guides 42 on the frame, and on this bar are fixed a series of forked clenchingplungers 43, Figs. 7, 8, and 9, the branches of which pass up at each side of the anvil 12 and clench the prongsp of the button onto the washer. The bar 41 is actuated simultaneously with the bar 37 by means of the cams 24, levers 25, rollers 26, and rods 44, which extend up from the levers 25 to the respective ends of the clenching-bar.

Figs. 10 and 11 illustrate a slightly different form of the clenching device. In this modification the branches 43 of the clenching-plungers are hinged, so that they may spread apart in clenching, being held against spreading by a U-spring 43.

Obviously the ratchet feeding device, which rotates the drums A and B intermittently, will be set to operate when the button setting and clenching devices are at rest.

The washers may be filled into the magazine 33 by drawing back the follower 34 and inserting them in front of the latter. There may be a keeper-shield 45 about the drum B above the magazines to insure against the placed washers being dislodged.

The hollow journals of the drums A and B are made large in order to afford strength and rigidity to resist the heavy strain put on these drums in the operation of tufting and to provide room for operating the plungers for driving and clenching the buttons wholly inside of the drums, thus avoiding a long stroke of the plungers. As these latter must withdraw clear of the drum, so that the latter may rotate, it is found in practice that the strain on the drum is apt to throw it out of line with the plungers when the latter have a long stroke and pass diametrically through the drum from above, as in some forms of these machines.
