IMPROVEMENTAIN`MCHINES FOR COLORING COTTON,-WOOL, &c.

Specification,forming-part of Letters Patent No. r181,429., dated August 22, 18'76 application filed June 26, 1876.

To all whom it may concern Beit known that we, JOHN T. RICE and DAVID A. ARNOLD, both of Pawtucket, in the county of Providence and State of Rhode Island, have jointly invented an Improvement in a Machine for Coloring Cotton, Wool, &c., of which the following is a specification:

The nature of our invention consists Iin combining with tanks suitably arranged a four-motion plunger, said plunger being provided on its under side with a series of teeth or projections, which, in the operation ot' the machine, engage with the mass of ber to be colored and press it into'the liquor, at the same time giving it motion toward the exit end of the tank, finally pressing it forward so thatit may be caught by the wringing-rolls.

Figure lis a side elevation of our invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is an end elevation of the same.

We first provide a tank, A B, having two compartments-a lower one, C, Fig. 2, which serves as a reservoir from which the liquor is pumped into the working part D. The lower compartment O also serves as a drip-tank,

into which the liquor' that' is pressed out by' the wringing-rolls E F runs. l

H H H H are inclined standards, attached ,to the tank A, and serve to hold the shaft K,

Figs. 2 and 3. The shaft K has at its-ends two crank-disks, M M, to which pitmen M1 and M2 are attached. These pitmen M1 and ,M2 connect by slots'm m, Fig..1, to a crosspiece, M3, Fig. 3, so that,as they move up and down, they will transmit a part of their motion to said cross-piece M3, and through it to the plunger L. The plungerL is also con,- nected to the uprights L' L', Fig. 3, which are slotted so as to embrace the shaft K, and thus serve to limit, and to some eX- tent direct, the movement of the plunger L. The pitman M2 has an extension, M4, Figs. l and 3, which carries a loop, N, Fig. l.

The system of levers and llinks N1 N2, P, QQ', and R, Fig. l, work asl follows: The bent lever N1 N2 is pivoted at n, and its` cud N1 is moved by the loop Nattached to the pitman M2 M4. P is a link, which serves to connect the lever N1 N2.with the lever Q Q', which is connected by the link R to the crosspieceM3 of the plunger. As the pitman M2 M4 descends it acts, for a Vpart of its stroke,

on the lever N1 N2, and through it and the link P, lever Q Q', link R, and cross-pieceplunger to move backward at the times when the parts of the strokes of the pitman M1 do not act on the levers and links. Then the pitmen M1 M2 are llifting or depressing the plunger L. Thus the combination gives a four-motion action to the plungerthat is, the the plunger, which is provided with teeth or studs p p p p, first moves downward onto the contents of the tank D thence forward, taking the cotton or wool toward the wringingrolls E F; then upward, free from the cont'ents ofthe tank; then backward and down again, to act as before on the contents of the tank.

To use our invention, we proceed as follows ThetankD is filled with the liquor or Idye with which it is desirable to saturate or color the varticles to be worked upon, and the machine is set in` motion. Then the cottonor other matter to be acted Aupon is passed over the roller V, 0r it may be fed in by rollers and an, apron. The plunger comes down and presses the mass into the liquor, and then moves it along toward the exit or wringingrollers E F. The amount of this forward` movement may be limited by an adjustment of the loop N, so that it may'act more or less on the lever N1 N2. Then the plunger is withdrawn and passed back to repeat .the

operation.

Havingnow descrlbed the-construction and operation of our invention, what we.claim is as follows:

l.A In a coloring-machine, the combination of a concave tank, D, the plunger L, the

slotted uprights L' L', and the shaft K with the actuating mechanism, all operating together, substantially as described, and for the purpose set forth. v

2. The combination of the pitman M2, the lever N1 N2, llink P, lever Q Q', and vlink R with the cross-piece M3, and plunger L, all operating substantially as described, and for the purpose set forth.
