MACHINE FOR WINDING SILK.

SPECIFICATION forming part of Letters Patent No. 256,949, dated April 25, 1882 Application filed May 20, 1881. (No model.)

Be it known that I, JOHN E. Arwoon, of Stonington, in the county of New London and State of Connecticut, have invented certain new and usefulImprovements in Machines for Winding Silk and other Fibrous Materials, of which the following is a specification.

Myinvention, though applicable to machines for winding fibrous materials generally, is particularly intended for machines for winding what is known as hard silk.

The object of my invention is to enable the bars to which the hangers for swit'ts are attached to be adjusted inward to economize space when small swifts are being wound from, and at the same time and simultaneously to be adjusted upward, so as to bring the portion of the swifts which the attendant has most to reach always at about the same height and position.

The invention consists in the combination, with adjustable bars and hangers for swifts attached thereto, of supports or receivers constructed with upwardly-converging slideways or slots, and means for holding said bars after their adjustment in said slideways or slots; also, in the combination, with the above, of knee-rails adjustable inward and outward.

In the accompanying drawings, Figure 1 represents a transverse vertical section of a machine embodying myinvention,certain parts thereof which do not relate to the invention being omitted for the sake of clearness; and Fig. 2 represents a side view of a portion of the machine.

Similar letters of reference designate corresponding parts in both figures.

The frame of the machine is composed of transoms A A A A uniting them.

B designates the shafts upon which are the driving-wheels a, for turning the bobbins b, and c designates the traverse-bars, all of which parts are similar in construction and operation to other winding-machines.

C designates the swifts, which are shown as arranged in two rows upon opposite sides of the machine, and are supported in hangers D,

which are attached rigidly to the bars E.

F designates a support or receiver for the bars I), composed of abraeket or hanger,

which is bolted to the under side of the transom A as seen in Fig. 1, and is constructed with arms or projections d, which are bolted to the under side of the two transoms A One of these hangers or brackets F is to be placed at each end of the machine, and others intermediately between the two end ones, if the machine be long enough to render it necessary. The brackets or receivers F are constructed. with slideways or slots 6, which re ceive in them the ends of the bars E,to which the swift-hangers D are attached, and which converge upward toward each other. The bars E fit loosely enough in the slideways or slots e-to permit of their being moved transversely therein.

The swifts C on the left hand of Fig. l are larger than the swifts upon the right hand of said figure, and are the largest swifts for which the machine here shown is adapted; and it will be seen that the left-hand bar E is in its lowest position in the slideway or slot 0 in the bracket or hanger F. It will also be seen that the right-hand bar E, to which are attached the hangers D, carrying the smaller swifts, is moved upward and inward in the slot or slideway 0, and is held in such position by apin, f, inserted transversely across the slideway or slot through holes 9 in the bracket or hanger, and having the bar resting upon it. If the swifts upon the left hand side of Fig. l were of the same size as those on theright hand, of course the left-hand bar E would be adjusted into the same position as the right-hand bar, and would rest upon a similar pin, f. If a. smaller size of swifts than either of'the two sizes shown are to be wound from, the bars E would be raised to their highest positions in the slideways or slots 0, and would be held in place by the pins f being inserted through other holes,g,in the two brackets or hangers.

Thus it will be seen that I provide for adjusting the bars E to suit three different sizes of swifts; but, if desirable, the machine might be constructed to permit of a wider range of adjustment. The slideways or slots 0, which receive the bars E, being inclined,it is obvious that when the bars are moved upward in them not only are the swifts moved inward and the machine narrowed and the space occupied by it reduced, but the switts are also raised; and

hence the portion of the swift that the attendant has to reach, which is just in front of the top, is always kept at about the same height, whether large or small swil'ts are being used, and hence can always be conveniently reached. As the swifts are moved inward, it is desirable that the knee-rails G be also moved inward, as otherwise the attendant would have to reach farther over the knee-rail to reach the Swifts. To provide for this the end frames, A, are constructed with projecting arms A, and the arms G of the rails G are secured thereto bymeans of bolts h, fitting in slots 6 therein. i

By my invention I provide a winding-machine inwhich small swifts are just as'accessible to the attendant as large swifts,and which, when winding from small swifts, may be narrowed, soas to considerably reduce the space which it occupies.

What I claim as my invention, and desire to secure by Letters Patent, is-' 1. The combination of the adjustable bars E, the hangers D, attached thereto, the supports or receivers F, constructed with upwardly-converging slideways or slots 0, and means for holding said bars after adjustment, substantially as specified.

2. The combination, in a winding-machine, of the adjustable bars E, hangers D, attached thereto,the supports or receivers F, constructed with upwardlyconverging slideways 6, means for holding said bars after adjustment, and the knee-rails G, adjustable inward and outward,substantially as specified.
