CLOTH SHRINKING AND PRESSING MACHINE.

Specification of Letters Patent.

To all wlwm it may concern:

Be it known that I, LESTER Ro'rHsoHILD, a citizen of the United States of America, and resident of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Cloth Shrinking and Pressing Machines, of which the following is a specification.

The object of my invention is a machine in which cloth from mills may be shrunk and pressed to an extent such that it will undergo no further shrinkage under the tailors iron, nor become spotted in case the tailor, in ironing, should use too damp a cloth, and in which means areprovided for preventing the cloths being marred when the operation of the machine is stopped. This object is attained by the means described in the specification and illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of a cloth pressing and shrinking machine embodying my invention. Fig. 2 is a plan view thereof. Fig. 3 is a central vertical sectional view of the same. Fig. 4 is a detail sectional view taken upon line ii -v of Fig. 3.

Referring to the parts: the frame of the machine consists of sides, A, A, which may be braced apart in any suitable manner. The rod, 6, upon which the roll of cloth, B, to be treated is wound, is journaled in notches, a, in the sides, A, A. Adjacent to the roll, B, a shaft, G, bearing a brush, C, is mounted. Between the sides, A and A, a series of steam cylinders, D, are journaled. The shafts, d, of the cylinders, D, receive pinions, d upon the exterior of the side, A, the said pinions, cl, being placed in gear with each other by a series ofintermeshing Beneath the cylinders, D, a water pan, A is mounted between the sides, A and A. Adjacent to one end of pan, A a wringer composed of two rollers, A and A is mounted, the roller, A*, being made adjustable in vertical ways, a, in the walls, A, by means of a screw, a An endless cloth apron, A, is placed around the cylinders, D, and projects into the pan,A and passes between the rollers, A and A The roller, A, is connected by means of a belt, a

to one of the stud shafts which receives rotation from the shaft, d, of the cylinders, D. Roller, A carries a pinion, a, which meshes with a pinion, a upon the roller, A, to

communicate rotation thereto. I

vertlcally above the cylinders, D, are a series of steam rollers,E, which are provided with means of moving them toward and from the cylinders, D, simultaneously. This means consists of the following elements: The ends of the cylinders, E, arejournaled in frames E, E which contact with the external faces of the sides, A and A, and have lugs e and c1, projecting into vertical ways, a, in the sides,Aand A. The frames, E, E are engaged by vertical screws, 6 6 which are journaled in brackets, 0 0 upon the sides, A, A, of the frame and have secured to their upper ends bevel pinions, 6 c", which mesh with pinions, e secured upon a. horizontal shaft, E The frames, E, and E with their elevating screws, and the horizontal shafts for communicating motion to the elevating screws are similar for each side, A, A, of the machine and need, 'therefore be described for only one side. Shaft, E terminates at the discharge end of the machine in a bevel pinion, 6 which meshes witha bevel pinion, e upon a vertical shaft, E*, which is journaled in brackets secured to the frame and near its Patented Dec. 28-, 1909.

. Application filed June 29, 1908. Serial No. 441,007.

lower endfcarries a pinion, 6 which intermeshes with a horizontal worm wheel, a, which may be turned by means of a crank, 6 Below the worm wheel, e shaft, E carries a pinion, 6 whose teeth engage a rack, F, which is mounted in, ways, 7, upon the end of the frame-work, and whose opposite end carries a fork, f, as

shown in Fig. 2, for engaging the belt, for

ering or raising the frames, E, E to carry the cylinders, E, toward or away from the cylinders, D.

Above the cylinders, E, a pan, H, is mounted between the sides, A, A, between which are mounted rollers, a and a and also rollers, a, 00 the latter two of which form a wringer, the roller, a, of which is made adjustable toward and away from the roller, a in a manner similar tothe rollers, AF, A-. Motion is conveyed to the rollers, a a l", from the cylinders, E, by belts, 00 a, indicated dotted line upon: 1 7 Anendless apron, A, passes around the Fig.

cylinders, E, the rollers, a, a between the wringer, a", a and through the water pan, H. The ends, E of the cylinders, E, have axial bores into which project branch pipes, is, from a steam pipe, K.

Adjacent to the cylinders, 'I), I have mounted auxiliary cylinders, M, M, between the frames, A, A, and above the cylinders, M, M", I have mounted auxiliary adjustable steam cylinders, N, N. The cyl inders, N, N, are carried by adjustable frames, n, n, which are mounted upon the sides, A, A, in a manner similar to the frames, E, E, and are provided with elevating screws, 11,, which have pinions meshing with bevel pinions upon the shafts, E in a manner similar'likewise to elevating screws of the frames, E, E The cylinders, N, N, however, are provided with an additional means for obtaining an extra pressurebetween thecylinders, N, N, M, To attain this object, I have provided frame, n, with bushings, n Each bushing, n is swiveled in frame, a, and its upper end is provided with teeth, n, which engage a worm, 11?, whose end is provided with a hand wheel, '11,. So that by rotating the worm, a a rotation may be imparted to the bushing, 11. to cause it to feed itself up- ,ward or downward on the elevating screw,

in without imparting a rotation thereto. By this meansl am enabled to obtain an extra pressurebetween the cylinders, N, and M, and N and M, without affecting the pressure between the cylinders, E, and D. Upon the side of the frame A, I have mounted a yoke, R, which carries pinions, r, 1", for communicating motion 'to the chain of gears, which rotate the shafts of the cylinders, D, E, N, N, and M, M. The pmion, 1', may be changed-when it is desired to change the speed of the machine. I may use cylinders, E, D, for shrinking and ressing, with or without the cylinders, l\, N,

7 I will describe the operation first without the last mentioned cylinders. Water having been placed in the pans, A H, steam having been admitted to the cylinders, E,

crank, 6 is turned, thereby moving rack, F, to throw the belt "upon the fixed pulley of the shaft, G, and rotating the shafts, E, E and the screws, 6 so as to movethe frames, E, E toward the cylinders, D, so

that the proper pressure is obtained between the cylinders, D and E. The rotation of the shaft, G, is imparted by the gear wheels to the cylinders, D, E, and thewringers, ro tating them in the direction indicated by the arrows in Fig. 3. The cloth from the roll, B, is then fed in between the aprons, A A", which feed it forward between the pressing rollers. The brush, 0, contacts the nap of the goods in order to lay it in one direction, before entering between the pressing rollers.

tween the rollers it receives both a thorough and uniform shrinkage, and is pressed without spots or gloss. Should it be desired to stop the machine for any purpose, the movement of the crank, 0 which throws off the power, simultaneously raises the steam cylinders, E, out of contact with the cloth being treated, so that there are no marks made upon the cloth, as would be the case were the steam cylinders held in contact with one part of the cloth for any appreci a'bl'eflgngth of time.

Should it be desired to give an extra finish to the cloth, as is the case with certain kinds of goods, the auxiliary cylinders, N, N, may be brought to bear against the cloth by moving the hand wheel, a". The pressure between the cylinders, M, N, N and M, may be adjusted to the degree desired independently of the adjustments to the cylinders, D, E, but when the crank, 0 is moved to throw ofl the power, the elevating screws, n simultaneously will raise-cylinders, N, N, together with the cylinders, E.
