To (1i/ZZ wl/ot it may con/cern:

Be it known that I, JOHN GLASGOW SAN- DERSON, engineer, a citizen of England, residing at Salford Iron Works, Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in AFabric-Printing Machines, (for which I have applied for a patent in GreatBritain, No. 12,074, dated May 27, 1902,) of which the following is a specification.

This invention relates to machines for printing fabrics of the kind in which the printingrollers are forced into and out of contact with the fabric at predetermined intervals while the fabric is being printed. For this purpose endless revolving chains are employed, these having suitable projections fixed at the required distances apart, so as to act as the measuring apparatus for regulating the intervals of contact of the printing-rollers. The chains can be lengthened or shortened, so as to obtain a great number of diversity of intervals or contact. As the chains travel the projections on them through suitable mechanism actuate an arrangement for throwinga clutch in and out of gear. When the clutch is thrown in gear, motion is given to cams having projections that force the printing-rollers out of contact with the fabric andhaving depressions which allow the rollers to be forced back into contact with the fabric by weights or springs or the like. Preferably the cam-shaft passes through a tubular shaft carrying the main bowl of the printing-machine, which shaft revolves in suitable bearings in the side frames.

In the accompanying drawings, Figure 1 is an end elevation of a fabric-printing machine having my improvements, while Fig. 2 is a side elevation thereof, partly in section. Fig. 3 is a side elevation, and Fig. 4 an end elevation, of the measuring apparatus.

Like letters denote like parts in the several views. Y

It will be seen from Fig. 2 that this machine has seven auxiliary rollers, or nips, as they are called; ebut these form no part of the invention and are here shown actuated by spiral springs; but the usual weights or levers will suffice. The five nips u1 un um uw uv are arranged for printing. The first nip uis used as a drag-roller and the seventh nip et as a driving-roller to insure constant and steady rotationof the printing-machine bowl.

,The main driving-shaft of the machine a is journaled outside of the machine and is driven by any suitable power. (Not shown.)

TheAgear-wheel aI is keyed to the shaft an and has a long boss, a portion of which has a brass bushing in which is supported the end of the cam-shaft f, which revolves in the hollow shaft of the printing-machine bowl supported in suitable bearings in the frame of the machine. The shaft feXtends through the machine and is keyed at its opposite end to the gear-wheel d, as hereinafter referred to.' The printing-machine bowl is drivenby friction of the printing-rollers or nips u1, un, um, uw, and uv, and of the roller uw. The gear-wheel atl drives the printing-rollers ul, et, and um, the roller u, and the wheel b. The latter is keyed to the shaft c, which drives one member of the clutch e through the gears cI cu cUI cw. The other member drives the cam-shaft f through the gear-d.I du. The gear-wheel d alsodrives the rollers uw and uv.

The clutch e is engaged and disengaged by movement of the lever s, which is operated bythe vibrating frame and the measuring device. The latter comprises two chains gl g, traveling on adjustable chain-wheels h h, respectively, on shaft km, which are driven from shaft cV by gear k1 ku. Thesev chains hang freely at their lower ends and carry suitable tappets w at distances apart corresponding with the required distance between the impressions of the printing-rollers. The tappets w engage with lever-arms Z l on shafts m1 m, respectively. Journaled supports or guides y are provided at that point where the tappets w encounter the lever-arms ZI and Z to hold the tappets up against the lever-arms. The latter have lever-arms oI oII for depressing the levers 101 pu, respectively, and thereby'tripping the vibrating frame q, as hereinafter described.

The frame q consists of a flat bar connected at its upper end to the pitman r of the eccentric fr and is adapted to reciprocate in two guideways. Near the center of the frame q is a slot through which projects the lug su ofthe link s, which is slidingly mounted IOC behind the frame q and is `providedat its upper end with a slot in which is seated the lower arm of a bell-crank s. The other end of the bell-crank s has a pin connected thereto which rides in a peripheral groove in the journal of one member of the clutch e.

Upon the outer face of the vibrating frame q are projections, one above and one below the slot, upon which are journaled the levers p1 and p". The levers pl and@Il are normally held in the position shown in Fig. 3 by means of spiral springs. The lever pl has its outer arm extending upwardly from its bearing and the lever p has its outer arm projecting downwardly from its bearing.

vThe vibrating frame q is reciprocated in two guideways in front of the link s1 by means of the pitman rl of the eccentric r, keyed on the shaft jl", which is driven from the shaft cv, through the gears c1", jl, j, andjm.

When a tappet on the chain gI encounters the lever ZI, the arm 0l depresses the lever p1 against the force of the spiral spring behind it, and on the upward stroke of the frame Q the depressed lever p engages with the lug s, which projects from the link sI through the slot in the frame q. The link s1 is therefore forced upward, and through the bell-crank s, to which it is connected, the clutch e is thrown into gear. Similarly, on the down- .ward stroke ofthe frame q the lever p, which is depressed as the tappet passes under the end of the lever l, encounters the lug s and throws the clutch out of gear. When the clutch e is in gear, the cam-shaft fis set in motion through the gear dt d and the cams ifI t tm V comeinto operation. In the machine here shown, designedfor printing shawls or the like, one pair of the cams forces the bodyprinting rollers out of contact and the other pair brings the cross-border-printing rollers into contact with the fabric being printed. When the cross border is completed, the same pair of cams forces this pair of rollers out of contact, the other pair of cams bring the body-printing rollers into operation, and the lever p operates the bell-crank lever s to disengage the clutch e, thus bringing the cams to rest, while the body-rollers continue their printing until the next tappet causes the engagement of the clutch e.

It will be seen that for variation of the intervals of contact of the rollers it is only necessary to change the length of chains or the distance between the tappets thereon.

Having thus described the nature of this invention and the best means I know of carrying the same into practical effect, Iclaiml. A machine for printing fabrics, comprising a two-membered clutch, one of the inembers of whichfis connected witha prime mover, a cam-shaft, gearing for operating said camshaft and driven by the other member of said clutch, printing devices, mechanisms operated by the cam shaft for intermittently throwing the printing devices out of operathrowing the printing devices out of operai tion, lever mechanisms for throwing the two clutch members into engagement, and means actuated by the prime mover for operating said lever mechanisms at predetermined intervals for the purpose specified.
