Application filed August 15, 191.4. Serial to. 856,900.

To all whom it may concern:

Be it known that I, Lns'rnn ROTHSCHILI), a citizen of the United States of America, and resident of Cincinnati, county of amilton, State of Ohio, have invented certain new and useful Improvements in Machines for Finishing Cloth, of which the following is a specification.

The shrinking process to which cloth is subjected before it is made into garments leaves most kinds of cloth in a rough and The problem of removingthis condition without stretching the cloth has been one the solution of which has bafiled the trade, heretofore. This is particularly the case with cloths of loose weave or of a texture which makes them subject to stretching. v p

The object of myinvention is to provide a machine which will remove the rough and unfinished appearance leaving the cloth with a high smooth finish, and with what the trade terms a soft handle without stretching it. 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 machine embodying my invention. Fig. 2 is a longitudinal sectional view thereof, taken upon line 22 of Fig. 3. Fig. 3 is an end elevation thereof. 7

The machine embodying my invention. comprises a steam cylinder, a conveyer sheet which is to be fed upon the steam cylinder, and to engage the cloth to be treated and to wind it upon the cylinder between the layers of the conveyer sheet, a means for holding it is being wound upon the steam cylinder, and

a guide roll for the cloth, which will feed the cloth in a flattened condition to the con-' veyer sheet to be carried forward by it and wound with it upon the steam cylinder.

Referring to the parts, the conveyersheet A is made preferably of canvas, and-is to be stored upon the roller B which is journaled in the frame D of the machine. Adj acent toone of the journals of the shaft B a friction bar B is pivoted upon the frame and is provided with a weight B which holds the friction bar in contact with the shaft of the roll B, to retard the rotation theredf and put the conveyer sheet under tension when it is being wound upon the steam cylinder. The steam cylinder E is journaled in the frame, and has in its walls a series of radial holes 6. Between the roll B and the steam cylinder E a series of rolls Z2, b, 72 are journaled in the frame, and afford means for assisting in keeping the conveyer or leader sheet taut. The feed roll F, upon which the cloth to be finished is wound, is ournaled like-wise in the frame, and between 1t and the steam cylinder guide rolls f, f are'journaled.

J ournaled in the frame is the driving shaft Gr upon which pulleys g and g are loosely journaled. Pulleys g and g are provided with clutch teeth, adapted to be engaged by clutches g and g which are splined upon the shaft and are provided with levers g and g for throwing them into firm engagement with pulleys g and g. Pulley g is connected by a belt 9 with a pulley secured upon the shaft of the steam cylinder E. Pulley g is connected by a belt 9 with a pulley secured upon the end of the shaft of the roll B. Adjacent to the sheet roll B elongated journal slots a are formed by L- shaped irons a for the receptions of the ournals of a roller H, which bears loosely upon the periphery of the roller B.

In operation the cloth to be finished is wound upon the feed roll by applying a manually operated crank to the square end 7" of its shaft. Clutch g being thrown into engagement with pulley g rotation is con veyed from the main shaft G to the steam cylinder E and the conveyer sheet B, then starts to feed under tension upon the steam cylinder. The operator then brings the forward edge of the cloth to be finished over the guide rolls f and and inserts said end between the conveyer sheet A and the steam cylinder E. The guide rolls 7 and f keep the cloth to be finished spread transversely so that it is fed smoothly on to the steam cylinder, between the layers of the conveyer sheet,which being held taut flattens the cloth smoothly between its layers as it is fed upon the steam cylinder, but without subjecting it to any longitudinal strain. After the cloth to be finished has been fed on to the steam cylinder, steam is admitted thereto, escapes through the holes 6 and permeates the cloth. The steam is thus permitted to permeate the cloth for a few minutes, the length of time depending upon the character of the cloth. Then the steam is turned off and the cloth is permitted to cool somewhat while remaining upon the cylinder. Then the clutch g3 is thrown into engagement with the pulley g,

which rotates the feed r011 B and starts to V rewind the conveyer sheet thereon. The end of the cloth is placed around' the roll H Which is rotated by its being held in contact with the feed roll 13, by its Weight; As the cloth accumulates upon the roll H its jour-' nals rise in the guide ays a. After the cloth is reWound upon the rolLH it is lifted;

from the guide ways a and removed from the machine. V v i Vhat I claim is:

bination of a frame, a feed roll for the cloth freely journaled in the upper part of the frame, a second feed roll for a conveyer sheet journaled in the frame beneath said 'first feed roll, means mounted upon the frame for retarding the rotation of the second feed roll, a perforated steam cylinder feed roll; tension rolls between the steam rolland the second feed roll over' which the sheet i is 'led to the steam cylinder, guide rolls located between the first feed roll and the 'stea'm cylinder upon which cloth from'the feed roll is'adapted to rest in being led be- 7 tween the perforated steam cylinder and the conveyer sheet, means foradmitting steam Y tothe steam cy1inder,and meansfor rotat- In a, machine for finlshmg cloth, the com- 7 ing the steam cylinder. 3' v In testimony whereof, I have hereunto subscribed my name this 11th day of Aug, 1914.
