IMPROVEMENT IN FULLlNG-MACHIN-ES.

Specification forming partof Letters Patent No. 178,599, dated June 13, 1876; application filed February 21, 1876.

To all whom it may concern: 4 Be it known that I, CHARLES P. CooLIDGE, of Orange, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Falling-Ma chines; and do hereby declare the same to be fully described in the following specitication and represented in the accompanying drawings, of which- Figure l denotes a side elevation, Fig. 2 a longitudinal section, and Figs. 3 and 4 are transverse sections, of a fulling-machine provided with my invention, which relates, tirst, to amode of constructing each ot' the upper squeeze-rollers; second, to the combination of certain movable slides with the frame and the squeeze-rollers, such slides being to prevent contact of the upper with the lower of the squeeze-rollers; third, in adjustable jaws, combined with the squeeze-rollers, and having mechanism tbrsimultaneously moving them (the said jaws) toward or away from each other.

Of the drawings, the section termed Fig. 3 is taken through the squeeze-rollers and their. supporters, while the section termed Fig. dis just in advance of the adjustable jaws, the longitudinal section being taken between the jaws ot' one pair. y

In the drawings, the case or frame of the machine is shown at A, there being extended laterally through it a driving shaft, B, provided with two langed squeeze-rollers, C C, arranged as shown. Each of the said rollers has flanges a a at its ends, between which anges one of two upper or other squeezerollers, D D, is placed, these latter rollers being fixed on a transverse and horizontal shaft, E, supported in boxes F F, and geared to the driving-shaft by two gears, Gr H. As in other machines, the boxes F F have springs a. a for pressing them downward, but each of the said boxes rests on one ot' a pair of slides, b b', arranged within a vertical opening, c, made in the side of the case, the lower slides b b being long enough to prevent vthe peripheries of the upper squeeze-rollers from contact with those of the lower rollers. The upper slides b b are fastened by screws c' to the top d of the' box orl frame, and thus limit said top.

the height to which the upper squeeze-rollers can rise without coming into contact with the The lower slides also serve to determine the distance to which the upper squeezerollers may approach the lower ones. The lower slides rest directly upon the drivingshaft. The vertical openings c and their pairs ot' slides b b admit ofthe driving-shaft and its squeeze-rollers being removed from or applied to the box of the machine. Each ot' the upper feed-rollers is composed ot' a metallic wheel, d', and a series of areal wooden sections, ce, applied to and extending around the periphery of the said wheel. Each areal section'has projecting down from its middle a tongue,f, grooved lengthwise to receive a key, g, which is dovetailed in cross-section, and somewhat tapering. Furthermore, the wheel has extending through it, at its periphery, a series ot' dovetailed grooves, h, to receive the tongues j'.

Fig. 5 is a top view of one of the wheels without its wooden covering, from which it will be seen that there is to each of' the grooves a series of sharp projections, z', extending inward from its sides. On the tongue of an areal section being inserted in the groove, and a dovetailed key being driven into the tongue, the latter will be spread into the dovetailed groove, and against the projections t, which, entering thel tongue, will prevent the section from working laterally out of the groove.

In front of each ot' the spaces between the squeeze-rollers ot' each pair is a pair of horizontal jaws, I I, arranged at a proper distance asunder, and havingbbetween them two movable vertical jaws, K K. These jaws, suitably jointed to move horizontally, have projections lo lo extending up from them. These projections receive a rotary screw-shaft, l, tixed in the frame so as to be capable of a rotary motion only on its-axis. The rod has one rightthreaded and one left-threaded screw to screw into and through the said projections, there bein g to the rod a milled head, m, to enable it to be revolved. On turning the rod one way the movable jaws will be made simultaneously to approach each other, counter movements of them being produced by revolving the rod the opposite Way. l The piece of cloth, having its ends secured or connected together, passes between a pair of movable jaws, and thence between a pair ot' the squeeze-rollers, thence through a box provided with a presser; .thence the cloth falls into the space within the box or frame, thence through the lifter of the stopmotion.

By having the jaws of each vertical pair of jaws adjustable and movable, as described, they may be readily set at their proper distance asunder, according to the thickness or quality of the cloth.

Having thus described my invention, what I claim in a fulling-machine vis as follows, viz:

l. The boX or frame A, having the slot c in each of its sides, and provided with the pair ot' movable slides b b to each of such slots, such'slides being` to limit the vertical moveas described, for simultaneously moving them' either toward or away from each other, and

between the stationary jaws, all being substantially as specified.
