CARPET-PLUCKER.

Specification of Letters Patent.

Patente l Nov. 14:, 1911.

Application led November 11, 1909. Serial No. 527,424.

To all whom tt may concern:

Be it known that I, JASPER C. OWENS, a citizen of the United States, residing at Hollywood, in the county of Los AngelesV and State of California., have invented new j and useful Improvements in Carpet-Pluckers, of which the following is a specification.

On heavy high piled carpet the edge is usually turned under to form a hem so as to make a finished appearance and durable edge. In order to make this hemmed edge so that its thickness is not excessive it is necessary to remove the nap from the edge portion which is turned under. Heretofore, so far as I am aware this operation has been done by means of cutting, a pair of shears being ordinarily used and the nap sheared off as Well as possible. This shearing operation leaves a portion of the nap still in the carpet fabric. If the nap is pulled out bodily the fabric is left clean and of a minimum thickness.

The present invention embodies a simple machine which will pull the nap from the edge ortion of a carpet in a simple and expedltious manner. The mechanism comprises a pair of grippers adapted to reciprocate to and from lthe carpet, which is automatically fed through the machine. A peculiar and novel mechanism operates the grippers to both move to and lfrom the carpet and to move to and from each other so as to grip the nap and release it after it is pulled out. The remaining mechanism consists of a simple and eiicient means for feeding the carpet.

In the present machine the strip from which the nap is pulled is removed a small distance from the edge of the carpet, there being left immediately along the edge a strip of small width, say one quarter of an inch, where the nap is not removed. At present this small amount of nap is sheared oft' after thecarpet has been put through the machine, but it will be obvious that the machine can easily be arranged so that it will pull'thenap from astrip Vdirectly adjacent the edge. It is only for mechanical convenience that the arrangement is made as shown, and this mechanical convenienceis thought to outweigh the'slight inconvenience of shearing off'the nap from the remainder of the strip along the edge.

In the accompanying drawings, Figure 1 is a longitudinal section taken on line 1-1 of Fig. 2. Fig. 2 is a cross section taken I26 and a cross head 'f-ra ne 27.

on line 2 2 of Fig. 1. I ig. 3 is a sectional elevation of a part of the machine taken on line 3 3 of Fig. 2. Fig 4 is a detail cross section taken on line 4- of Fig. 1.

In the drawings 5 des .gnates a supporting frame of suitable chiracter which carries a divided table 6 for the support of carpet 7. The carpet pa: ses over table 6 in the direction indicated bj' the arrow in Fig. 1 and at the center portion of the table passes under a feeding rc ll 8, this roll being luted or toothed to obte in a good driving grip on the carpet. The teeth may be made to project forwardly so a; to catch the body of the carpet and hold it in lace. The carpet is fed through tha machine with its nap 9 below, the nap projecting downwardly where it passes over feeding roll 8 so that it may be easily gripped and pulled out, as will be hereinafter described. A pair of -rollers 10 on ear h side of roller 8 press upwardly on the ca rpet and hold it in position against the feed roller. Rollers 10 are mounted on arms 11 jiivoted at 12 to the frame of the machine, the arms being extended and held downwz rdly on their ends by adjustable springs 13. Rollers 10'are thus resiliently held upyardly against the carpet and hold it tight] v against the feeding roll. Shaft 14, o1. which roller 10 shown on the right hanl side in Fig. 1 is mounted, projects throu gh frame 5 and is provided with a gear 1i on its outerend whichmeshes with a gi ar 16 mounted on shaft 17 of feed roller v8. This arrangement provides that roller 10 sl all be driven along with roller 8f so as to Jositively pull the carpet through the mac lline. Shaft 17 Of roller 8 is mounted in be irings 18 on frame 5 and is provided with a 'ratchetwheel 19 at its outer end for the purpose of driving it in the direction indictt'ed by the arrow. This ratchet wheel is re folved through the medium of a pawl 20 n ounted on the end of an arm 21 which is op erated by an eccentric 22 on main operati 1g shaft 23 of the machine. When shaft 53 is revolved arm 21 will be reciprocatei. .and the ratchet wheel 19 will be intermittently rotated. The carpet will thus be fed in successive short movements throug'i the machine.

Mounted on frame 5 i5 a pair of vertical wa s 25, these ways hol ling a slider frame Cross head frame 27 is reciprocated vertically through the medium of a horizon tal slot 28 in which shaft 34. Shaft 23 is ordinarily driven by i hand but may be equipped for power driving if desired.

Slider frame 26 in the upper part of ways l 25 is provided with two pivots 35 whichy These grippers are support grippers 36. provided on their upper ends with nap engaging noses 37 and have extensions 38 be- To their lower ends are pivoted links 39, pivoted together at 40 and low pivots 35.

connected to a vertical rod 41 at that point.

Rod 41 extends downwardly and is secured 5 at 42 to cross head frame 27, the rod being screw threaded and a turn buckle 43 provided for adjustment of its length.

the first operation is the closing together of the upper ends of the grippers. When cross head frame 27 moves downwardly the inner ends of links 39 are pulled downwardly .and the lower ends of the grippers spread apart until the upper ends grip the nap between them tightly. lDuring this portion of the movement slider frame 26 is prevented from moving downwardly by means of a small spring v45 which presses against the slider frame and affords sufficient friction to hold it in place. By adjusting the pressure of spring 45, the downward pull necessary to move the slider frame, and the pressure between the two grippers, may be regulated. When the grippers can be no longer moved about their pivots the remaining downward motion of the cross head frame will move the slider frame and grippers together bodily. On the subse uent upward movement of the cross head rame the lower ends of the grippers will first be contracted and the upper ends separated, so that the pulled nap is dropped. As soon as the links reach such a position as is shown in the drawings the upward component of their pull is suflicient to move the slider frame and grippers again to the position shown.

Ledge 50, against and under which the carpet travels, is made adjustable as shown in Fig. 4. The width of the pulled portion may thereby be varied within the limits'of the width of rollers 10, it always being necessary to keep the carpet in engagement with the edge -rollers to a small extent.

The arrangement of the different parts of the machine is so made that the carpet is only fed through as fast as the grippers can remove the nap. In the present construction the grippers operate continuously while the carpet is fed intermittently. This specific arrangement, however, is of no importance, it being possible to feed the carpet continuously if desired. To remove the pulled nap from the machine a blower or any other approved means may be used. If necessary, the machine may be doubled, one set of grippers acting on the carpet after the other has pulled most of the nap, thus cleaning the carpet thoroughly.
