IMPROVEMENT lN MACHINES FOR PRESSINGv FABRICS.

' The Schedule referred to in these Letters Patent and making part of the same.

To all to whom 'it may concern Be it known that we, GEORGE HENRY NUssEY and WILLIAM BRADsHAw LEACEMAN, both of Leeds,

in the county of York, England, have invented certain new and useful Improvements in Machinery or Apparatus for Pressing Wollen and other woven or felted fabrics; and we do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of our invention relates -to a novel arrangement of hot and cold rollers or cylinders, as hereafter described, so as to dispenseentirely with the process called papering, and thereby saving much time and expense heretofore attending the finishing of woolen and other woven or felted fabrics.

On two suitable frames which are parallel with each other we place, by preference, four rollers or cylinders. The first pair of the aforesaid rollers are hollow, and are heated by. steam Vorother suitable means. The second pair of the aforesaid rollers are cold, and not necessarily hollow, although they may be so and su'p plied with cold water or other chemical preparations if necessary, so as to set the nap after passing through or between the hot rollers, and thus keeping the bo'dy in the cloth.

To the underneath rollers of the aforesaid hot and cold rollers pressure is applied by levers and weights or other mechanical means, the aforesaid hotand cold rollers being capable of adjustment in, the direction of -the upper rollers of the aforesaid hot and cold rollers.

In order that our said invention may bemore completely understood we annex two sheets of drawings,

in which- Figure l represents an end elevation Figure 2, a side elevation Figure 3, a plan Figure 4, a section of a top roller; and

Figure 5, a section of a bottom roller.

It will be seen that we have illustrated a 'machine worked by power, but it is evident that we can vsubstitute a winch-handle for the 'driving-pulley.

a. a are the standards and frame-work of the machine.

b l), the hot rollers,

c c, the cold rollers.

(l d represent friction or tightening rollers.

,lhe fabric is first passed between the friction rollers to give the necessary tension before passing between the hot rollers; after the hot rollersit is passed between the cold rollers for the purpose of setting the nap.

c e are levers, and i f f are weights, by which means an upward press- I ure is given to ,the bottom rollers. This pressure may be increased or diminished td suit the various kinds of fabric by altering the position or size of the weights.. v

The bottom rollers run in sliding-bushes g g, iitting in correspondingr guides in or on lthe standards a a.l

rlhe'upright rods h-h transmit the pressure given by the levers and weights to the bottom rollers. y

'i i e' are tables or supports for the fabric as itpasses to and from the rollers.

The table at the bael; of the' machine is continued ,suthciently far to allow the attendants to fold or cuttle the fabric. i

The tables "i i yi are. supported by brackets -fixed on the standards a a.

Each roller is provided with a feed-pipe, K, through which hot or cold duid is supplied, and also with a waste or overflow-pipe, l, through 'which the superlluous fluid is allowed to escape. Each pipe is connected with the roller by a stuffing-box, fm, which is packed iu such a manner as not to allow any leakage of the fluid as it ent-ers or passes olf from the rollers.

'lhe end ot' each pipe insideV each stuffing-box has a` collar, by preference turned conical, as shown, and working against a bush of brass or othersuit-able material, as shown. The tubes or pipes are securely held in their required position by means of suitable brackets. i

Tubing of any suitable `kind maybe attached to w the ends of the pipes K and Z. This depends on the y position and nature of the supply of fluid.

The rollers have each a V-grcove, O, turned in them at each end. This prevents any of the lubricating substanceffrom the'bearings getting to the fabric loperated upon. l

The driving-pulleys may be keyed onto the boss of the driving-pinion, which gears with the spur-wheel on the top rollers; a loose pulley `also runs on the boss of the pinion. runs on a stud carried by one of the standards.

Having. now described the nature of our said invention, and the manner. in which the same is to be performed, we would remark that we do not limit ourselves to two hot and cold rollers, as any required number may be added, in the manner shown by dotted lines in iig. 2. Neither do we limit ourselves to the exact details and coniigurationbf parts, as' the same may -be of course varied or modiiied without departing' from the nature and principle of our iuventiou. y
