IMPROVEMENT IN APPARATUS FOR STEAMING PRINTED FABRICS.

Specication forming part of Letters Patent No. 215,173, dated May 6, 1879; application iiled November 19, 1878; patented in England, October 8, 1875.

To all 'whom 'it may concern:

Be it known that I, JAMES SMITH, engineer to Messrs. Walter Orum & Oo., of Thornliebank, in the county of Renfrew, North Britain, have invented certain new and useful Improvements in Apparatus for Subjecting Printed or other Fabrics to the Action of Steam; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the annexed drawings, forming part of this specification.

For the fixation of the colors on printed goods, such as calico, it is necessary they should be subjected to the action of steam.

My invention pertains to an ilnproved apparatus for carrying such fabric into and through a steam filled chamber, as hereinafter described.

Referring to the drawings, Figure 1 is a longitudinal vertical section, and Fig. 2 is a transverse section, of my improved apparatus. Fig. 3 is a detail view of part of the mechanism for moving the chains, and Fig. 4 is a detail view of one of the chains.

The steaming-chamber a. is constructed of a rectangular form, and may be of any required or convenient length and height, the dimensions being determined by the rate of progressive motion of the fabric, so that while it is continuously passing into and out of the chamber each part of it may, in progressing from one end to the other, occupy the time considered necessary for obtaining the proper and complete action of the steam.

The chamber c is represented as constructed with brick or stone walls, and with a steamchest, b, forming the ceiling; but the requisite space may be inclosed by any other suitable construction.

The fabric is indicated by the lines c, and while in the chamber it is suspended in long vertical loops or loose folds on transverse horizontal rods d, and the ends of these rods rest on two parallel endless chains, c, placed horizontally, and the links of which are formed with cavities or seats for the rods, and for keeping them at regular distances apart. The endless chains are .at one end passed round a pair of polygonal pulleys, f, on a transverse horizontal shaft, g, which is driven slowly, as hereinafter explained, and at the other end the chains pass round pulleys 7L on a shaft, the bearings of which are adjustable by screws, by which the chains can always be properly distended. The chains c slide along guiderails carried by brackets flXed to the side walls, as shown in Fig. 2.

In the entering arrangement, (shown in Fig. 1,) the fabric is drawn forward by the rollers i, and it drops in a fold between two of the rods d, which are carried into the chamber c by the large ratchet-wheels j, Xed to the ends of the drum k. The rods d are placed on the inclined steam-chest l, ready to be taken up bythe ratchet wheels j. The rollers z' are driven at such a speed relatively to that of the chains c as to supply the extent of fabric required for forming a loop or fold of the desired depth between each rod c and the one next to it. Thedrop-pawls m hold the fabric against the rod while the fold is being made.

At or near the farther end of the chamber a the fabric is drawn off by the roller a, and the rods d drop olf the endless chains c as the chains turn round the pulleys h into a trough or other receptacle.

The motion is given to the rollers c' and to the chains c by a strap passing around the pulley o1 on the driving-shaft o, and by the spur-wheel 02, gearing into a pinion on the first roller i, the second roller c' being driven by the first. On the shaft o is also the worm o3, gearing'nto the wheel p1 on the diagonal shaft p, near the lower end of which is the worm p2, gearing into the wheel g of the shaft g.

I have described the driving-gear as shown in the drawings; but it may be arranged in any other convenient way.A

The steam is admitted into the chamber a., by preference, by the horizontaLpipe q, near the bottom of the chamber, and the pipe is perforated at the sides, so that the issuing jets of steam may not blow drops of water against the fabric. The steam-chest bis provided with steam through the branch b2, and the surplus steam from the steam-chest passes down the pipe b3 into the chamber.

The fabric, on entering and leaving the chamber a, passes through slots in the steamchest. By this means all drops due to condensation are prevented from falling on the fabric in the chamber. Said steam-chest also prevents condensation along the top of the l rollers being located as described, the chains chamber, so that no drops of waterof' condeng for carrying the rods, pulleys f and h, mechsation are deposited thereon, and hence none Il anism for feeding the rods to the chains, the can fall on the fabric While passing through g Worm-shaft, and the gearing for connecting the chamber. the feed-rolls and the pulley f, all substan- I do not claim the endless traveling chains, tially as shown and described. nor the mechanism for presenting the rods to In testimony whereof I have hereto set my said chains, nor tbe steam-chamber provided hand before two subscribing Witnesses. with a steam-chest in its upper portion; but i what I do @1mm is- JAMES SMITH' In an anaratns for steamingr fabrics the Witnesses:
