Specification of Letters Patent.

Original application filed January 20, 1909, Serial No. 473,245. Divided and this application filed March To all whom it may concern Be it known that I, HARRY LUKE Owns, a citizen of the United States, residing in Schenectady, county of Schenectady, New York, have invented Improved Means for Applying Coverings to l/Vires, of which the following is a specification.

This invention relates to a means for facilitating the application of asbestos fibers to wires in forming insulated electric con ductors.

According to my invention I am able to receive the asbestos fiberdirectly from the carding machine upon a suitable temporary backing of conveying material, upon which it is deposited in the same state as delivered by the dotfer rolls thus retaining its flocculent condition. Thistemporary backing is a flexible, ribbon-like sheet, which with the deposited flocculent asbestos is; wound up into a coil on a reel or bobbin, so that it may be stored for future use or inserted directly into the wire-covering machine for application of the asbestos upon the wire.

In the accompanying drawing, Figure 1 is a partial sectional elevation of the delivery end of a carding machine showing the method of preparing the coil of asbestos fiber on its backing; Fig. 2, is a section of the reel and coil on alarger scale; Fig. 3, is a plan view of a part of the machine shown in Fig. 1; and Fig. 4, is a side view of the roll of asbestos on its ribbon-like backing when removed from the bobbin.

In Fig. the main carding drum is iridicated by 1, while one of the set of dotfer wheels is indicated at 3. In the rear of the set of doffer wheels 3, I place an eccentric or cam shaft 4, to impart a vertically reciprocating motion to the combs 5, which are can ried by a shaft- 15, one comb being supplied to cooperate with each of the (lotfer wheels 3. On a lower plane and adjacent to said combs 5 is rotatably mounted an idler roll (3, over which the tapes 20 of any suitable material, are drawn, while below said roll 0 is. mounted another idler roller 7, upon which rests the flanges of therunwinding rccls. Each of these reels is made up of a hollow hub or spindle 3 and the. removable flanges 9 which are held in place on the reduced ends by the. circular nuts 10, scrcwthreaded upon the ends of said spindle b7 and formed each with a groove it in its periph- Serial No. 616,814.

erv. place lengthwiseof the supporting shaft by the friction springs 12 which are secured to the cross-bari3 and have their free ends engaging the grooves 11 of the reelspiiidle.

The reels are detachably detained in Th'usthe. reels are permitted to be rotated as the tape is unwound therefrom. The springs 12 are placed in positions each to' retain a tape reel' opposite a dofferwheel. At the rear of the combs I provide another set of tape reels of similar construction and interchangeable with those of the first set, but these reels of the second set are for.

winding up. Under this second or winding up set of reels'is mounted the driven shaft 1 T, upon which are keyed or otherwise se- Said wind secured in placeion its supporting spin le by the springs 12 will:have its outer end brought up over the roller 6 and thence to the winding reel driven by the shaft 14 so that said tape will be wound up on saidwinding reel' by the action of the friction disk 15. The directions of movements of the several moving parts are indicated by the arrows in Fig. 1. As the tape 20 is thus transferred from one reel to the other, the

combs are reciprocated by the revolution of the shaft 4 and the asbestos fiber is thereby combed-from the dotfer wheel 3 down upon thetraveling tape 20, which is being wound with the-depositedo asbestos upon" itself on the winding up reel. The'asbestos fiber is retained and protected by the successive coils of said tape 20 whichserve as a temporary backing therefor. When the reel filled it can be readily removed from, the machine and transferred tofa suitable wire covering machine for application of the asbestos fiber to the wire. \Vhcn emptied of the fiber and its ribbonlike support the reel can be returned to the carding machine to be refilled.

From the foregoing description it will be I soon that any suitable width of tape may be emplovcd and that the asbestos fiber will be depositedthereon' in'a. perfectly even state and the thickness of the deposit upon the tape may be regulatedby the speed at which 1 '-tlie tape is made to travel.

I do not in this application intend to claim either themechanism for or the method of preparing the roll of the ribbonlike support carrying the asbestos as they form the subject of my application for pat- 7 cut filed January 20, 1909, Serial No. 473245 a web of flocculent asbestos fiber detachahly supported thereon.

2. As a new article of manufacture, a flexible sheet or ribbon-like support, having a Web of flocculent asbestos fiber dctachably supported thereon, the ribbon and web being rolled up into a ball or reel.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
