MEANS FOR COLD-PRESSING CLOTH.

Specification of Letters Patent.

Patented May 5, 1914.

Application filed December 30,1910. Serial No. 600,056.

orcester, in the county of WVorcester and State of Massachusetts, have invented certain new and useful Improvements in Means for Cold-Pressing Cloth, of which the following is a specification.

My invention relates to means for successfully cold-pressing cloth in arotary press, which will enable even an inexperienced finisher to do it safely, and without getting into trouble, or spoiling the goods being treated.

Attempts made by me with rotary presses (such, for instance, as patented on August 6th, 1878, numbered 206,718) to cold-press cloth by feeding cold water through the second bed, and steam only through the cylinder and the first bed, resulted in failure because the heat from the hot cylinder and that contained in the cloth would, when the cloth reached the second or cold bed, cause water of condensation to form upon the second bed to such an extent, and so fast, that after a few yards were passed through the machine, the material would commence to pucker and stick, and then refuse to pass out, becoming eventually torn and completely ruined. Similar results were had, though not quite as bad, when cold water was put into the cylinder, and steam only in the two beds. With a very light pressing merely, the cloth would pass through the machine safely, but water of condensation would form so fast and in such quantity upon the cold surface of the cylinder as to spot the cloth and blotch it. So this, too, was given up as impractical.

I now have devised means to COldTPl'GSS a piece of cloth successfully by making provision for removing the water of condensation forming upon the face of the cold, or chilled, pressing-member when in close proximity to a hot pressing-member, by taking care of it as fast as it forms thereon, and I do not moisten the cloth to such an extent as to cause it to stick during its passage through the machine, or to watenspot and become blotchy, and thereby unsalable. And I can do this while at the same time administering to the goods a very substantial pressing, instead of escaping disaster only by resorting simply to the lightest kind of pressing, which was the best we were heretofore able to accomplish because of failure to solve the most essential question: how to dispense with the water'of condensation inevitably forming very rapidly upon the cold pressing member, when opposed by a hot pressing member.

The invention consists in the improvements to be fully described hereinafter and the novelty of which will be particularly pointed out and-distinctly claimed.

I I have fully and clearly illustrated my in-' vention in the accompanying drawings to be taken as a part of this specification and wherein Figure 1 represents an end view of so much of a rotary press as is needed to show the application of my invention to such a machine; Fig. 2 showing the opposite end view thereof. Fig. 3 is a top View of the parts required to carry out my invention; and Fig. 4 is a frontview thereof. Fig. 5 is a longitudinal section through the moistureremoving roll. Figs. 6 and 7 show means for bringing the roll shown in Fig. 5 into or out of contact with the cold-pressing cylinder of a rotary press. Fig. 8 shows the relation of certain details to each other. Figs. 9 and 10 show another detail in two different positions necessary for properly handling the cloth.

Referring to the drawings by characters of reference, A is the cold-pressing cylinder of a rotary press, carrying next to its driving gear a between it and the frame B, another gear which drives not only the apron-draft-roll A, by meshing with the gear 0, upon it, but also the gear (Z keyed to one end of an arbor e, that has fastened to its opposite end another gear f. The arbor e revolves freely in a bracket 9 fastened on to top of frame, B, and the swing-arm h is strapped loosely to the bracket 9 by the caps i. Upon the opposite end of the machine there is fastened upon the top of frameB a bracket g upon which swings the arm it held upon it by the caps c". In the free ends of the swing-arms h and h is mounted to rotate a cylinder C, held down by the caps 71: and 7: and between one end of the cylinder C and the swing-arm h it has fastened to it a gear Z meshing with the gear f, which is fast upon the inside end of arbor 6, so

that, when the cold-cylinder A of the press revolves in the direction of the main driving gear a the cylinder C will turn in the same direction, as indicated by the arrows, and its surface will wipe that of the cold-cylinder A.

B is a hot pressing member preferably in the form of a bed, and coiiperating with a portion of the periphery of the cylinder A through an area of the latter preferably to one side of the axis of rotation thereof, said bed being heated by any suitable and well known means, as, for example, steam admitted to the interior thereof. It will be noted that the cylinder C contacts the cyl inder A on the opposite side of the axis of the latter from the bed B.

Referring to Fig. 5, it will be seen that the cylinder C has perforated. walls, thicker at one end than at the other, so that its in terior flares toward the head-end G which is provided with the head C that is of larger diameter than the opening at C of the cylinder C, in order that any water in the in terior of this cylinder can gravitate toward and run into the head 0. The opposite end of the cylinder G is closed by the gear I which forms also the head C While the j our nal P, being made in one piece with head C and gear Z, is sealed by plug P screwed into the end of the journal P.

Reaching into the head 0 is a station ary suction pipe D with its bent, or lowermost end D reaching to a level somewhat below that of the opening C in the cylinder C, so that any water that may get into the head C will touch the mouth end D of the pipe D, before it can reach as high as the lowermost edge of the opening C A bracket E juts out from the swing-arm h to hold the U-piece, or pipe G flanged at H to the suction pipe D, and held down fast by the clamp or cap F which is bolted to the bracket E,

J is a union which connects the U-piece G with the screw threaded end of the elbowpiece K, the opposite or smooth end of which is being held in the bracket g which forms an arbor for the swing-arm h, with its caps 2" attached to it, to swing upon (see Fig. 8). A vertical pipe L attached to the elbow-piece K is connected at its other end to a suction pump, not shown in the drawings, for removing not only what moisture might collect in the head C, but to create a vacuum in the interior of the cylinder C, which has its outer surface clothed with several layers of absorbent cotton cloth M in order to cover the perforations M in the cylinder C, so as to give the moisture absorbed by the cotton wrapper M from the wet surface of the cold-pressing cylinder, a chance to be withdrawn, together with the air, by the suction pump just referred to. The packing nut N screwed upon the sleeve 0 screwed to the end of the journal P makes an airtight joint between the interior of the head C and the e suction. pipe D, and the union J makes an airtight joint between the U-piece G and the elbow-piece K, held by the bracket 5/.

While the suction cylinder C will remove the moisture formed upon the outside of the cold-pressing cylinder A more thoroughly when driven as just described, I can, particularly on light-weight goods, dispense with this gearing, and let the cylinder C simply revolve and be driven only by contact with the cold-pressing cylinder.

As to which in ethodthe positively driven, or the frietioi'ially drivenis preferable is best determined by the amount of moisture container] in the fabric that is to be coldpressed. A fabric loaded with moisture before cold-pressing, will deposit very much more condensation upon the outside of the cold-pressing cylinder than the same fabric will do when fairly dry. Also, a lightweight fabric, even if given considerable moisture before cold-pressing, is less apt to wet the cold-cylinder as much as a heavyweight cloth given about the same degree of moisture before cold-pressing, because the heavy-weight will hold and retain more of it. Therefore, I build my machine with the gear-drive shown, when excessive moisture is made, and leave it off on ordinary work, where the cloth is loaded with less moisture before cold-pressing and gives off less condensation to the chilled cylinder when contacting therewith.

In the practice of my invention, it is desirable, when stopping the machine, to raise the cylinder C from the position it occupied during cold-pressing, as shown in Fig. 6, to that shown in Fig. 7 so that the absorbent cotton wrapper M which becomes damp, and more or less wet during cold-pressing, will not remain in contact with the cylinder A when the latter stands idle.

Although Figs. 6 and 7 show only one end of the machine it will be understood that what is said of this end, applies in the main to the opposite end, and a repetition of the drawings appears therefore superfluous.

Referring to Figs. 6 and 7, 71 is a bracket, fastened to the end of the swing-arm h, a. duplicate of this bracket being also fastened to the end of the swing-arm 72,, at the opposite end of the machine, and a flat bar 7L extending across the machine is made fast to both to unite them. Behind the bar 71 is fastened a link a, one near each end of the machine, to which is hooked a hook 711., at the end of a chain 0, which runs over the sheaves 7) and (j in posts Q. The other end of the chain 0 is secured to a sheave r fast upon the shaft 8 revolving in brackets 2" at the back of the post Q, one of which post... as already statedis fastened on top of the frames B at each end of the machine.

At the end of the shaft .5 extending beyond the post Q. is keyed a gear 6 meshing with apinion a running on a stud to secured to a bracket 2 and fixed to this pinion at is a hand-wheel o by turning'which the shaft 8 can be caused to wind upon the sheave r, a part of chain 0, or to unwind it therefrom; the shaft 3 carrying next to the frame B between it and the gear 6 a ratchet wheel a, with which cooperates a dog on swinging upon a stud 'w, screwed into the frame B, in order to lock the ratchet shaft 3 in any position desired; for instance,that shown in Fig. 7. Thus, the cylinder C may be raised out of or lowered into contact with the cold-pressing cylinder A whenever desired. 1 v V In my machine, patented August 4th, 1896, Number 565,072, the apron used is made of felt, which to a certain extent is elastic and yielding, and enough so, to allow dress-goods or light-weight fabrics to pass through the'machine in a continuous manner that is to say, with the ends of the pieces sewed together in order to make of them one continuous web of cloth, the impressions made by passing seams in the felt apron not being sufiiciently deep to mark the goods so as to render them objectionable. Hence, generally, a leader is sewed on to the .last piece of goods, as is customarily done when running an ordinary rotary press with no apron, and this leader is left in the machine after the days work is over, to sew onto it the following morning the first piece of another continuous web of cloth, consisting of many pieces of cloth sewed together endwise, like above mentioned. This is done, to do away with introducing each piece of cloth singly, which, as the machine is now constructed, would cause quite a delay of time, because it being intended for continuous use, no special pro-vision is made to render the introduction of the cloth into the mouth of the machine particularly easy.

In my present invention I prefer to use a cotton apron in place of the felt apron, as used in hot-pressing heretofore, because, to get the desired effect, I have to impart a harder pressing to the goods. And with the harder pressing, the goods cannot be sewed together any more in a continuous web, because the seams would damage my cotton apron, which is tin-elastic, and less thick than the felt aprons. Hence, when cold-pressing with a cotton apron, I have to introduce each piece singly, to avoid cutting the aprons, which a seam might do under severe pressure.

Referring to the drawings, the apron R after passin over' the draft-roll A", oes

down around idler rolls S and T, and com ing up in front of the machine, goes over the front roller V to the coldcylinder A. The front roller V (see Figs. 9 and 10) runs in swing-pads W, which turn on pivots or studs W and have toothed segments or circular racks W, into which mesh pinions X keyed upon shaft Z, which extends across the front of the machine and revolves in brackets 14 fastened to the frame B.

On one end of the shaft Z is fastened a hand-wheel Y which has a couple of holes 1 and 2 drilled into the side of its rim. These holes 1 and 2 register with a catch pin 3 in order to hold the hand-wheel fast in the two positions shown in Figs. 9 and 10, the catchpin moving in a hole drilled into an arm projecting out from the bracket Z.

'By this means when the hand-wheel Y is turned to throw the apron roll V backward, as shown in Fig. 10, an open mouth or triangular pouch t is formed bet-ween the cyl inder A and the'apron R in its passage from the roll V toward the cold-cylinder into which mouth I the end of a piece of cloth can conveniently be placed by the. operator, and smoothedout by him to make sure of a proper start. When, after placing the smooth end of the cloth into this mouth, or pocket 4, the roll V is thrown forward again, as in Fig. 9, and the apron will hold the cloth against the cylinder, so that when the machine is started and cylinder A and apron It move forward together, the cloth will be held flat and smoothly between the.
