TO ALL WHOM IT MAY CONCERN:

Be it known that I, A. C. CORPE, of Sta'ord, in the county of Tolland, and State of Connecticut, have invented a new and improved Machine for Stretching Cloth; 'and that the following specification, taken in connection with the accompanying drawings,- hereinafter-refcrred to, forms aiull and exact description of thesame, wherein I have set forth the nature and ,principles of my said improvements, byA which vmy invention may be distinguished from all others of a similar class, together with such parts asvI claim, and desire to have secured to me by Letters Patent.

f Ths invention relates `to a new and improved machine for stretching cloth, with aview of rendering the same smooth, and unfolding such portion of the selvedges which may have been rolled over -in the manipulations to which it-was subjected after being taken from the'loom. l v

The invention consists of two horizontal gear-clamps and rollers, all placed in a suitable frame, and arranged to operate as hereinafter set forth. In the accompanying sheet of drawings- Figure 1 is a plan or top view of my invention. VFigure 2 a vertical section of the same, takenin the line my, iig. 1.

Similar letters of reference indicate like parts.

A'represents a frame, which may be constructed in any proper manner-'to support the working parts, and B B represent two'horizontal gear-clamps, each of which is composed of two gear-wheels,l a a', placed, one directly over the other. The lower wheels a are perfectly horizontal, their axes b being vertical, and fitted loosely in guides or bearings c attached to a cross-bar, d, of the frame A. The upper gear-wheels a of the clamps are slightly inclined from ahorizontal plane, their outermost parts being rather nearer Ythe faces or 'upper surfaces of the lower wheels a than their inner parts, as shown in iig. 2. This position of the upper wheels a is obtained by having their axes e fitted in bearingsf, which are placed in upright sockets g on a cross-har, h of the frame A, the bearings having a certain degree of adjustability in a lateral direction in the sockets, and held in place by set-screws z', which pass through thesockets, as v vill be fully understood byreferring to gf2. By this arrangement it will be seen that the cloth, shown inred, which is drawn between the wheels a af of the clamps,

`will be clutched or griped between the outer parts of said wheels. The cloth passes from between these wheels over a roller, C, in the frame A, andis wound upon a roller, D, in the upper part of a frame, E, the lower end of which is fitted loosely upon a shaft, j, at the lower part of thefranie A. rlfhs roller D is rotated through the medium of gearing from a. shaft, z', at one side of the frame E, motion being communicated to it from a driving-pulley, through themedium of gearing n and a clutch, o, `the latter being operated by a lever, p, so as to connect the gearing'n with the driving-pulley m, or disconnectit therefrom, as may bedesired. The upper and'lower wheels a a. of the gearelamps B B gear into pinions'q g on barrels F, on the upper ends of which there are also bevel-pinions r, which gear into bevel-teeth s 'at the inner sides of wheels t, which are toothed at their peripheries. d C. The barrels -F work loosely on upright xed axes v on the frame A, and on the upper ends of the axes e of, the upper 'wheels a of the gear-clamps there are secured circular heads w, against the under sides ofI which:

eccentrics a. bear, which eccentrics are to raise the upper wheels a. These eccentrics have levers bx attached for the convenience of operating them. j y u i From the above description it will be seen that, when the roller D is turned, the cloth will be drawn between the gear-clamps B B, the latteiturning simultaneously, and with the same motion, as they are both connected with the roller C, and these gear-clamps will stretch the elth laterally and unrollthe selvedges wherever turned over, Inadjusting the cloth between the upper and lower wheels of thegear-clamps, at the commencement of the operation, the upper wheels a are raised by adjusting the eccentrics a,and, when the cloth is secured to roller D, the upper wheels are lowered, so as to bear upon the cloth. v

Having thus described my invention, I claim as new, andd desire to secure by LettersP-atent- 1. The two gear-clamps B B, composed each of two wheels, a a', one placed above the other, and the upper wheels arranged so as to be capable of adjustment both vertically and laterally, substantially as shown and described.

2. I claim the arrangement of gearing as shown, in connection with the gear-clamps B B and'roller C, vwhereby an equal movement of the clamps is insured, substantially as shown and described.

3. The supplemental frame E, provided with the roller D, upon which the cloth is wound, in connection with the gearing k u, clutch o, driving-pulley m, and shaft l, all arranged substantially as shown and described. The above specification of my `invention signed by me, this 23d day of April, 1867. j
