IMPROVEMENT IN CLOTH-MAPPING MACHINES.

Specification forming part of Letters Patent No To all whom it may concern:

' Be it known that I, MARCIENE H. WHIT- 00MB, of Holyoke, Hampden county, Massachusetts, have invented a new and Improved Machine for 'Nappin g Cloth, of which the following is a specification:

My invention consists of amachine for napping cloth, combining on one frame the wire or card napper and the teasel-eylinder, the

- object being to have the strength of the Wire or card clothing for breaking or tearing up the fibers of strong, heavy goods, for which the power of the teasel is not sufficient, and have the teasels for finishing the nap, 'for which they are superior to the card.

Figure l is a longitudinal sectional elevation of my improved cloth-napping machine, taken on line a; a, Fig. 2. Fig. 2 is a plan View with a strip of cloth shown on one side, and Fig. 3 is a detail of the manner of attaching the teasels. V

Similarletters of reference indicate corresponding parts.

A represents the wire or card nappers, and B the teasel-cylinder. The cloth 0 is first pre- 'sented to the wire nappers and then to the teasels.

The teasels are packed in a frame composed of bars E and F and rods G,'Which are fastened to the cylinder. I

The small carrying-rollers H are covered with short wire-clothin g, to takestron g hold of the cloth and prevent slipping. The' cloth is drawn over the teasel -cylinder by the large I back roll I, also covered with wire. This combination is employed for very coarse and heavy cloth, which is very. hard to nap, and has always been done on gigs and singlecylinder nappersmostly on nappers. All manufacturers preferred the gig, but the cloth being so very hard and heavy, it tore the teaselsin pieces, which made it expensive and l77,602,'dated May 16, 1876; application filed March 6, 1876.

a slow process; so they resorted to nappers covered with card-wire. The nappers reduce the weight of the goods very much more than the teasels, but are quicker.

In this machine I combine the two processes, using the Wire for preparing the cloth for the 1 teasel, so that it can raise a nap without pulling the teasel in ieces, or reducing the Weight of the goods. I save over any other process of napping over an ounce per yard.

In regard to its capacity, it will be seen that I present the cloth to each of the napping cylinders twice, and as there are twocylinders, it makes four touches, and to the tea-sel-cylinder three times. It is perfectly ad-- justable, so that the cloth can beapplied to the cylinders as light or as hard as is desirable,

so that one passage over the machine finishes that side oftbe piece, while on the machines in general use it takes from six to ten runs.

One man on this machine will do the work of. two or three, and it is better done, with less waste, and a great saving in room, as this machine does the Work of eight or ten singlecylinder ones. I

The cost for clothing, teasels, &c., is much less than any other napper.

I propose to employ any arrangement which conducts the cloth from napping to teasel cylinders continuously.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of card-nappers A, tease]- eylinder B, and teasels D, the latter packed in a frame, E F G, on the cylinder, substantially as and for the purpose specified.-
