CLOTH-SUBFACING DEVICE.

Application filed July 2,

To all whom it may concern:

Be it known thatI, VILLIAM E. Ross, a citizen of the United States, residing at Chi-' cago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Cloth-Surfacing Dcvices, of which the following is a specification.

The present invention relates to devices for surfacing materials, such as cloth, and has particular reference to the raising of a nap upon the surface of the cloth.

Among the objects of the invention are to provide an improved method and device for rasing a nap upon the surface of cloth or the like; to provide the device with angularly projected burred bristles or bristles with burrs at the free ends thereof capable of entering into the cloth a substantial distance and then leaving the cloth while raisi'ng a nap so as to leave a raised or lifted nap on the surface thereof; to provide a de vice so that the bristles will have a rolling and dragging action of a cl'un-acter which will cause the entry of the burrs into the cloth as a. relative motion is effected between the cloth and the bristles, the bristles having such resiliency that as they are caused to leave the cloth, the burrs will raise a nap and readily disengage themselves from said nap; to provide for adjustably varying the resistance to the rotary action of the bristles, preferably by an adjustable resilient frictional brake or the like whereby the drag on the bristles during peripheral movement of the bristles in a direction opposite to the direction of projection of the burrs will cause the barred ends of. the bristles to enter the cloth and also to travel along the cloth; to provide a device combining the features of nap raising burrs capable of entering the cloth, ressure for ausing such entry, and a frictlonal drag which, with the pressure applied and the 'relative movement of the cloth and the device, will effect the desired raising of the nap on the surface of the cloth; and to rovide such other and further objects, a vantages and capabilities as will later more fully appear and are inherently possessed by the invention.

Referring to the drawings, F ig. 1 is a side view of a device constructed in accordance with the inventionrFig. 2 is a yiew partially insection' on the line 2-2 of Fig. 1; Fig. 3 is a fragmentary detailed view in sec= tion of part 'of the device; Fig. 4 is a which is rotatably mounted or journaled a roller 5 carrying upon its periphery an annular set of bristles 6, aselearly shown in Figs. 1 and 2 of the drawing;l

The roller 5 is rotatably ounted upon a shaft or pin 7 having means at one end for connection to the arm 4 and being threaded at the other end to receive a thumb nut 8 having a hub portion 9 bearing against an end of a helical spring 10 hearing at its other end against a friction or drag plate or disk ll fastened to one side of the roller 5. At the other end of the shaft 7, in the form shown in 'Fig. 2 of the drawing, is formed a head 12 having a flange 13, the latter being cut sccantally to form a shoulder 14 abutting against a corresponding shoulder 15 formed in the arm 4. The cooperation of these shoulders prevents the turning of the shaft about its axis. The arm 4 has an opening or aperature within which the enlargement l2 fits, as clearly shown in Fig. 2 of the drawing. The enlargement 12 has a shoulder portion 16 having frictional engagement with a frictional or drag plate or disk 17 secured to the other side of the roller from that to which the plate 11 is secured.

In the form of device shown in Fig. 5, the mode of connection between the shaft 7 and the arm 4 is b way of a cross pin 18 extending througl the apertured end of the arm 4 and the end of the shaft passing thercthrough. In this waythe pin 18 prevents a relative rotation of the shaft 7 with respect to the arm 4. The end of the arm 4 is provided with a frictional surface 19 hearing against the outer face of a flat frictional or drag disk 20 secured to a side of the roller, and correspondin to the plate 17 in the form shown in l ig. 2 of the drawin The ristles are connected, preferably, in groups, and in circular series about the periphery of the roller, to form a substantially uniform operating surface, their inner ends'being fastened into the roller and their outer ends extending outwardly but not radially, althoufh curved in a general direction more or ess tangentially about the roller. The outer or free ends of the bristles are suitably formed, as by grinding while under pressure, upon an emery wheel or like or similar abrasive device, with angularly projected burrs 21 extending in the same general direction as clearly shown in Figs. 3 and 4 of the drawing. The bristles are preferably of metal and resilient, such as steel wire, and are so treated that they are not corr'odible. As shown in Fig. 3 of the drawing, the bristles are curved or inclined toward the direction in which the device is to be moved or drawn over the surfam of cloth or material to be treated.

It is to be understood that while a handoperated device is chosen to illustrate the invention, the invention also comprehends the idea of supporting the bristles in any manner desired so long as there is relative movement between the cloth or material to be treated and the bristles, in the direction above indicated, irrespective of whether or not the cloth be moved and the bristles held for rotation about a stationary axis or the bristle carrying device be moved as a whole relative to the cloth, the latter being in stationary relation.

In operation the device is used so as to cause a rolling of the roller 5 together with the bristles carried thereby over the surface of cloth such as the cloth piece 22 shown in Fig. 3 of the drawing. In order that the same will not ride idly over the cloth without producing the desired effect, a drag or frictional resistance is applied to the roll 5 by a suitable turning of the thumb nut 8 so as to compress the spring 10 to the extent of obtaining: the desired frictional engagement between an end of the spring and the friction disk 11 as well as the shoulder 16 and the friction disk 1?. Viiih the proper amount of frictional drag, should the device be drawn over the cloth in a direction corresponding to the direction of projection of the burrs 21, the roller and the bristles carried thereby will be rotated, thereby causing the burrs to penetrate the material a substantial distance. The bristles will be bent. or flexed somewhat as the burrerl ends thereof enter the cloth. and as the rolling continues, and the trailing, bristles which are lifted from the cloth will resiliently act in such a direction as to cause the burrs 21 to lift a nap out of the cloth so as to leave upon the cloth a nap 23 as shown in Fig. 3 of the drawing, the burrs leaving the cloth at such an angle as to readily disengage themeclvvs from the nap. This effect results from the travel of the device, together with the fric tional drag upon the roll, which cause the roll to rotate as well as to force the burred ends 21 to yieldably enter the cloth, result- 'ing in a reflex action of the bristles as the leave the cloth so as to cause the burrs to lift the nap.

While I have herein described and upon the drawings shown a preferred and modified embodiment illustrating the invention, it is to be understood that the invention is not limited to the particular construction details and arrangement of parts shown an described, but that other constructions, details and arrangements of parts are com prehcnded by the invention without departing from the spirit thereof.
