IMPROVEMENT IN GIG FOR CLOTH.

'ro ALL WHoM 1r MAY ooNoEnN:

Be it known that I, ORSEMUS M. STILLMAN, of Westerly, in the county of Washington, and State of Rhode Island, have invented a new and useful Improvement in GlothfGig; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which" Figure 1 represents a side View of my improved cloth-gig.

Figure 2 is a vertical central cross-section through the raising-cylinder and cloth-rolls.

Figure 3 is a partial top view, exhibiting transverse endless aprons for gig-ging erosswise of the cloth.

Figure 4 is a detached View of a cloth-beam, partly in section, showing the mode ofits connection, to permit attaching and detaching readily, for reversing the action of the teazles on the cloth.

Similar letters of reference indicate corresponding parts.

This invention relates to improvements in the construction and operation of gigs, for raising the nap upon woollen cloths, and consists in simple devices for bringing the cloth into contact with one raising-cylinder at four distinct points or places simultaneously, whereby nearly four times as much work is performed at the same time; and also, in connection therewith, a system of cross-gigging from one edge or selvcdge of the` cloth to the other, instead ofthe ordinary mode of teazling from the centre of the piece to the edges, in opposite directions, In connection with these devices for gigging the cloth longitudinally at four places on the raising-cylinder at a time, are simple devices forgraduatin'g the bearing of the cloth against the `teazles while passing over this raising-cylinder, and for lifting it clear of the teazles when required; and further, for changing thecloth-beams or winding-rolls end for end in the machine, and thus' reversing the operation of teazling without unwinding the cloth, as practised generally with the ordinary gig, for the purpose of raising the nap in thevopposite direction on the cloth. i

A is the raising-cylinder, hung in a suitable frame, B, on the axis a, connected with any motive-power, as desired. Below the raising-cylinder, on its opposite sides, are placed the windingrrolls or cloth-beams b b', and around the cylinder, near'to the surface, are placed live small guide-rollers, c e, suspended to the frame B. The clothbeams 6 b receive motion from the axis a by cog-gearing at one end of the cylinder, connected therewith,

as shown in Eg. 1, el being a pinion on the axisa, engaging a spur-wheel, d1, that gears into a spur-wheel, 2,7011

the axis g of one of thc cloth-beams, and by means of an intermediate wheel, e, actuates the spur d3, on the axis g of the other cloth-beam, b. The cloth-beams b are each formed with square recesses or' mortises in the ends, which fit alike on the ends of the axes or journals g y', in such manner that they may be taken 01T and changed end for 'end in place of each other. For this purpose, the journals g, on the ends opposite the drivinggear, are made to be taken, when necessary, out of their bearings, h', in which they are held by buttons or catches, lr, as shown clearly in iig. 4, or may be held in place in any suitable manner. The piece of cloth to be teazled is wound upon the front beam, b, and passes over the raisingcylinder A,`resting on the guide-rollers c e, in such manner that the surface of the cloth shall touch the teazlcs, for napping, at severalpoints between the rollers, as shown in lig. l. The cloth also bears upon and passes under an extension-roller, m, at the hack part `of the raising-cylinder, turning at right angles, and passing horizontally over two endless aprons or cross-bands, o o', iig. 3, (which travel in opposite directions,) and thence, over the rollers 'n n', to the'cloth-beam b', on which it is wound, or between perpetual rolls, when such are used. The cross-bands o o take their motion from reverse driving-pulleysppl, one of which, pl, is hung on a shaft, g, and the other one, p, on the sleeve e, upon the shaft q, actuated by bevel-wheels t t respectively, which gear into the same bevel-wheel,- r, or may be actuated in any other suitable manner. Opposite the pulleys 2i pl, the cross-bands o o' bear on counter-pulleys p2-p3, the whole being supported by a frame, C. The cross-banden a will carry teazles or cards, for the purpose of napA ping or'raising the fibre ofthe cloth crosswise, from side'to side, or from selvedge to selvedge, as it passes over the cross-bands, which travel in opposite directions, and thereby counteract the movement of each other, and, in connection with the extension-roller m, hold the cloth evenly and smoothly while it is 4being teazled transversely. The cross-bands o o are supported` andvborne upwards against the cloth by a board, w, which isi adjusted by raising or lowering,.as desired, to regulate the bearing of the teazles or cards. For regulating the bearing ofthe cloth against the teazles on the raisingwylinden two ofthe guide-rollers c c are made adjustable.

They are each hangin the ends of sliding'racks, iz', which are moved by pinions, jj, at each end, working in worms or screws, a: z', on the same shaft, z, at one end of the cylinder. By the elevation or depression ofthese two rollers, the cloth is raisedor lowered at four places, to adjustits bearing in contact with the teazles on the raisingk-cylinder,` and the guide-rollers may he elevated, so as to raise, entirely clear offthe teazles, the aprons, which are usually attached to the cloth, for the purpose of starting the work and of teazling at the ends. After the cloth has been passed over the raising-cylinder back and forward a few times, and is wound upon the back winding-roll b', the winding-rolls b b are beth taken from vtheir axes, k:ts-'previously described, and shifted in their places, end for end, and thus the operation of teazling will be conducted in an opposite direction to that previously performed, without unwinding the cloth. The guide-rollers e c may be so 4arranged that the cloth shall come in Contact with the raising-cylinder in three placesvonly, instead of four, as above described. Having described my inventiornl claim as new, and desire to secure by Letters Patent- 1. The combination and arrangement of the cross-bands o o', reverse driving-pulleyspp, counter-pulleys p' p3, adjusting-board w, shaft g, tubular shaft s, bevel-wheelst t 1', as herein described, for the purpose specified. 2. The arrangement of the cylinder A, rollers c, racks z', pinions j, shaft z, worm-wheels x, rollers mn n', reversible cloth-beams I: b', and gear-wheels ddl d d3, asilieren described, for the purpose specified.
