STRETCHlNG AND DRYING APPARATUS FORv CALICO-PRINTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 234,541, dated November 16, 1880.

Application filed August 6, 1880.

To all whom it may concern:

Be it known that I, FRANCIS JAMES CROW- LEY, of Gloucester City, in the county of Camden and State of New Jersey, have invented a new and useful Improvement in Stretching and Drying Apparatus for Calico-Printing Machines, of which the following is a specification.

My invention relates to a means for stretching, smoothing, and drying printed cloth, whereby crimps, wrinkles, or creases are prevented from being formed in the fabric before it passes to the drying-cylinders.

In the accompanying drawings, Figure l is a top view, showing the construction-and arrangement of the drying apparatus and the manner of connecting it with the drying-cyL inder. Fig. 2 is a front or end view. Figs. 3, 4, 5, and 6 are detail views.

Similar letters of reference indicate corresponding parts.

A represents a drying-cylinder, which may be of any suitable description and arranged in the usual or any suitable manner.

B represents a frame, which supports the working parts of the stretching apparatus.

In the upper portion of the frame B are journaled six horizontal shafts, D, arranged in two sets, three in each set. Each of these shafts carries three pinions, E, around which pass leather belts G. Each belt has riveted to itsinner side a series of ribs, f, which serve as teeth and engage with the teeth of the pinions E, so as to insure the proper and uniform revolution of the belts.

To the three belts of each set a series of slats, H, are attached. These slats may be made of brass or other metal. They are rounded on one side and flat on the other, and the flat sides are secured to the outer sides of the belts Gr.

By the construction and arrangement of parts above described two endless aprons are produced, moving in opposite directions from the center of the frame, as indicated by the arrows. Between the adjacent portions of the two aprons lies a stationary strip, J, of brass or other metal, having its ends secured to the frame B.

K K represent two rollers journaled in the frame B at right angles to the shafts D, and so arranged that their lower peripheries are (No model.)

slightly lower than the upper surfaces of the endless aprons above described. One of these rollers, K is provided with bevel-gearing Z, engaging with bevel-gearing m on two of the shafts D, so as to give motion thereto. The shaft of this roller K also carries at one end a gear-wheel, M, engaging with the gearing of the drying-cylinder. Y

The operation is as follows: After the cloth is printed it is passed under the roller K, thence over the slats H, thence under the rollor K and thence to the drying-cylinder. As the cloth moves along it is pressed down by the rollers K K on the slats H, and as the aprons move in opposite directions from the center the slats H stretch and spread the cloth transversely of its line of travel. Thus by the combined action of the slats and the rollers the cloth is delivered to the drying-cylinder in a perfectly smooth and even condition, and all crimping, wrinkling, or creasing is effectuall y prevented.

I am aware that stretchers to lengthen and widen cloth are not new; but this is not the object of my invention. When the calico comes from the dye-house it is twisted up like arope, and is run through a machine that opens it, but it still comes to the drying-cylil'ider full of creases or crimps, which are usually worked out with the hand. These crimps or double edges run so fast that the manipulators cannot straighten them out. Hence between the mai'iipulators is placed a machine to take out the crimps in conjunction with them. The calico is pressed so tightly on my cylinders and stretcher that it cannot be really stretched in length or width, this being a subsequent operation in the finishing-room.

What I claim as new and of my invention 1s The combination, with the drying-cylinder A and frame B, of the two sets of three shafts D, each carrying three pinions, E, the belts Gr, ribbed on the under side, the slats H, arranged across the belts, the rigid strip J between the aprons, and the rollers K K the whole adapted to remove crimps from printcalico and dry the same, as set forth.

FRANCIS JAMES CROWLEY.
