fiPECIPIC'ATION forming part of Letters Patent No. 367,070, dated July 26, 1887. A Application filed August 21, 1886. Serial No.21L489. (No model.) 7

T0 aZZ whom it may concern.-

Be it known that we, J OHN SHEARER, of the village of Preston, in the county of Waterloo, inthe Province of Ontario, finisher,and HENRY WILLIAM KAROH, of the village of Hespeler, in the county of Vaterloo, in the Province of Ontario, Canada, machinist, haveinvented certain new and useful Improvements in Double- Acting Rotary Gigs, of which the following is a specification.

The object of the invention is to provide means by which the cloth maybe run with or against the cylinder without stopping the ma chine or making any appreciable alteration in the gearing, and to so apply friction to the feeding-rollers that the tension of the cloth being fed into the machine may be regulated; and it consists in the peculiar combinations .and the construction, arrangement, and adaptation of parts, all as more fully hereinafter described and claimed.

Figure l is a perspective view of the gig. Fig. 2 is a perspective view from the opposite side. Fig. 3 is a sectional elevation of the machine.

In the drawings like letters of reference dicate corresponding parts. 7

In all gigs heretofore made there are none with which we are familiar in which the teaselcylinderis completelyinclosed, 'By our meth- 0d of construction the cylinder is completely inclosed by the sides A, endsB, and lids O, as shown in Figs. 1 and 2, so that the operator may examine the cloth, and at the same time be protected from any dust that may arise by the action of the teasel-cylinder D upon the cloth.

E is a receptacle placed underneath the teasel-cylinder and extendingacross it, so as to receive the flocks falling from the cylinder D. F is another receptacle, made in the I form shown in Fig. 3, and designed to keep the cloth clear of the ground.

G is the main driving-shaft, on one end of which is situated the spur-pinion H and on the other the loose pulleys I and J and fast or driving pulley K. One of these pulleys is driven by a straight belt and the other by a cross-belt. When it is desired to drive the cylinder in one direction, the belt is moved from the pulley J to the driving-pulley K.

I the feeding-roller.

Should it, however, be desired to drive it in the opposite direction, the cross-belt is moved from the loose pulley I to the driving-pulley K. As this system of pulleys and belts is common and well known, and as no claim is made thereto, we have not shown the belts in the drawings.

The gear-pinionH meshes with the gear- Wheel I), which is situated on the spindle M. On the same spindle is placed the bevel-pinion N, which meshes with the bevel-pinions O and U on the spindle 0. On the ends of this spindle are placed the bevel pinions Z and m.

n and p are bevel-pinions situated on the ends of the feeding or delivery rollers a and b.

P is a pivoted lever'having a forked end, q,

arranged to fit into the recess in the collar r I on the spindle 0. When it is wished to make the roller (1 a feed-roller, the end q of the lever P is brought against the collar 1", so as to movethe spindle 0 longitudinally and bring the bevel-pinions N and 0 into gear, and also the bevel-pinion m into gear with the bevel-pinion p, situated on the spindle of the feed-roller a. Should it, however, be desired to make the roller 1) the feed-roller, the lever P is moved so as to bring its forked end q against the collar r, so as to move the shaft longitudinally and bring the bevel-pinions N and U into gear, and also bevel-pinion Z into gear with the bevelpinion n on the end of the feed-roller b.

In Fig. 3 we show by dotted lines the course of the cloth as it passes through the machine.

For the purpose of illustration, we will suppose the roller (1, as represented in .Fig. 1, The cloth passes between the rollers b and d, over the roller 6, down to the roller f, whence it passes over the rollers z, 71', and g, and then down to the roller f, up to the roller e, and then between'the rollers a and c, and out of the machine. As shown in this figure, the points at which the teasels of the cylinder D operateupon the cloth are be tween the rollers f and gandff and i. As the cloth is joined together at some suitable point.

there is a continual operation upon the cloth ICO of nap on the cloth, or in one direction and then in the other to give a different nap to the cloth.

For the purpose of regulating the extent of surface of cloth upon which the cylinder D is to act, we pivot on the frame A spur-pinions j arranged to mesh with the racks, 7:, upon the outer ends of which the rollers i and g are pivoted. These spur-pinious j are operated by hand from the outer side of the machine by sprocket-wheels :v and chains 2, operated by means of winches '20, as indicated in Fig. 2. In this figure we also show on the ends of the spindles of the rollers a. and I) grooved pulleys Q, to which are applied the friction-straps B. These straps are connected to thejaws of the pivoted levers S, which are adjusted on the quadrants T by the thumb-nuts i. \Vhen the cloth passes out of the machine between the rollers b and d, the thumb screw i may be adjusted so as to bring such a friction upon the pulley on the end of the roller a as to give the desired tension of the said roller upon the cloth passing into the machine.

It will be seen from this description that our machine may be easily operated, may be used as an up-and-down gig, and that by our sys tem of bevel-gears the motion of the cloth may be changed without stopping the machine.

W'hat we claim as our invention is- 1. The combination, with the teasel-eylinder and its inclosing-frame, of the receptaeleE beneath said cylinder, and the receptacle F for the purpose specified.

2. The combinatiomwith the main shaft and feeding-rollers, of a spindle arranged at right angles to said main shaft, bcvel-pinions O U on said spindle intermediate of its ends, bevel pinion N, means for imparting motion thereto from the main shaft, the pinions Z m n p, and means for shifting said spindle endwise, sub stantially as and for the purpose specified.

The combination, with the frame, shaft G, spur-pinion H, spur-wheel L, bevel-pinions N O U, and spindle 0, of the bevel-pin ions 1 m at opposite ends of said spindle, the rollers a b at opposite sides ofsaid frame, and the bevel-pinions p n on said rollers a I), respectively, and means for moving the said spindle endwise, substantially as described.

l. The combination, with the roller a and pulley Q thereon, ot' the quadrant T, lever S, thumb-nut t, and friction-strap R, passing over said pulley and connected to said lever, substantially as and for the purpose specified.

Signed at Preston this 6th day of August, 1886.
