To all whom it may concern.-

Be it known that I, GERMAN LYoNs, of Lawrence, county of Essex, and State of Massachusetts, have invented an Improvement in Supports forWire-Boards of Spinning-Frames, of which the following description, in connec tion with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to devices for supporting the guide-wire board of a spinning-frame in its tipped-up position and for releasing the said support to permit the guidewire board to return to its normal position.

The invention is embodied in an apparatus comprising a wire-board-supporting lever pivoted on the front of the roller-beam below the wire-board on an axis at right angles to the front of the rollerbeam, so that the said lever turns in a plane parallel with the front of the roller-beam. The said lever is provided at one end with a supporting-shoulder that engages the rearward under edge of the wireboard or of a metallicplate or bracket attached thereto when said wire-board is in its tippedup position, and the other end of the said lever is weighted, so as to tend to turn the lever on its pivot in the direction to bring its supporting'shoulder into operative position when the wire-board is tipped up. The apparatus also comprises a disengaging lever or handle pivoted on the under side of the wire-board, and having its handle end project out between and beyond the guide-wires, while its other end has a projection that engages the supporting lever in such manner that when said handle is turned on its pivot it moves the supportinglever laterally from the position in which it supports the wire-board, so that the latter may return to its normal position by the action of gravity upon it. The supportinglever has a plate which is engaged by the handle-lever as the Wire-board descends, and thus continues to turn the supporting-lever during the movement of the wire-board to its normal horizontal position. These devices are simple and reliable, and are also compact, occupying but small space on the spinning-frame, and being conveniently operated without having to reach through or between the yarns that extend from the guide-wires to the spindles.

Figure 1 is a front elevation of a portion of the wire board and roller-beam of a spinning frame provided with a support for said wireboard embodying this invention, the parts being shown in the normal position occupied while the spinning is going on; Fig. 2, an end elevation of the parts shown in Fig. 1, and Figs. 3 and 4 similar front and end elevations showing the devices in the position occupied when the wire-board is in its tipped-up position.

The roller-beam a and wire-board, b, hinged thereto, as shown at b, and provided with separate hinged guide-blocks 0, one to each spindle, carrying the guide-wires d, by which the yarns are guided in their passages from the drawingrolls to the spindles, are all of the construction now commonly used in spinning frames. The said board b extends a considerable distance along the spinning-frame and supports a large number of separate guideblocks, 0, so that by turning up the said board, as shown in Figs. 3 and 4, a large number of guide blocks and wires are raised, so as to permit the easy removal of the bobbins from the spindles.

In order to support the wire-board b and guide-blocks, 0, attached thereto in the tippednp position, as shown in Figs. 3 and 4, the spinning-frame is, in accordance with this in vention, provided with a supporting-lever, e, pivoted at e on the front of the roller-beam a, the said pivot e being at right angles to the front of the roller-beam, so that the lever e turns parallel with the front faces of the roller-beam and occupies but little space with relation thereto. The said lever may be composed of a fiat strip of iron, which is bent at one end, as best shown in Fig. 4, to form aseat or support, e", against which the wire-board b rests when in its tipped-up position, and the said lever is provided at its other end with a weight, 0*, that tends to turn the lever on its pivot c from the position shown in Fig. l to that shown in full lines, Fig. 3, the said lever being prevented from turning this way as long as the wire-board is in its normal position by the engagement of the upper or unweighted end of the lever with the under side of the wire-board.

The portion of the wire-board immediately over the lever is provided with a metallic plate or bracket, f, that engages with the sup porting-lever e, as best shown in Fig. 4, and thus prevents the marring or indentation of the wire'board, which might take place if the said board rested directly upon the lever. The said platef also forms the support for the disengaging-handle g, which is pivoted at 1 upon a forwardly-projecting portion, f, of said plate, the end of the handle 9 projecting out between a pair of adjacent gnidewires, as will be readily understood from Figs. 2 and 3.

The movement of the handle 7 on its pivot is limited by a stop, 71, shown as consisting of a screw or projection attached to the plate f and extending through a slot, It, in the lever g, the inner end of which has a projection, 9 that co-operates with a projecting portion, 0*, of the supporting-levcr, which portion 0 is beyond the seat 0 and is substantially parallel with the plate f when the board is in its tipped-up position, as shown in Fig. 4.

The weighted supporting-lever c, in coming from the position shownin Fig. 1 to that shown in full lines, Fig. 3, will carry the disengag' ing-handle g to the position shown in full lines, Fig. 3, when the said handle will be arrested by its stop, and will itself prevent the lever from swinging by its momentum beyond the uprightsupporting position shown in full lines, Fig. 3.

When it is desired to restore the wire'board to its normal position (shown in Figs. 1.an(l2,:) this can be done, without reaching in between the yarns to operate the supporting-lever, by means of the disengaging-handleg. The operator turns the said handle from the position shown in full. lines to that shown in dotted lines, Fig. 3, in which movement its end 1 engages the end 0 0f the lever c and turns it to the dotted-line position, Fig. 3, from which the weight of the wire-board will continue to turn it in the same direction, andin thedownward movement of the wire-board the end 1" of the disengaging handle will bear on a plate, c at the side of the lever c, and thus continue to turn the said lever out from beneath the the yarns and cannot possibly interfere with I the yarns.

The supporting devices may be placed at or near the middle of the wirehoard, and thus n support the same with less strain than if placed near one end thereof,and the wireboard may be lifted by an operator at any point in its length, as the weighted snpporting-levcr will automatically come to the position to support the wire-board, turning the handle 1 to the fnllline position, Fig. 13, if it is not at ready in such position.

I clain1- 1. The combination of the roller-beam and wire-board of a spinning-frame with a wireboardsupporting lever pivoted on the front of said roller-beam and a handle cooperating with said lever, pivoted at the under side of the wireboard, substantially as described.

2. The wireboardsnpporting lever pivoted on the front of the roller-bean1 below the wireboard, and provided at one end with a weight and at its other end with a wire-hoard-supporting seat and a projection beyond said seat, and a contact-plate, combined with a plate or bracket attached to the under side of the wireboard, and a handle pivoted on said bracket, with one end extending out between a pair of gnidewires and its otherend co-operating wit h the projection and contact-plate ol' the weighted wire-boardsnpporting lever, substantially as described.

Intestimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
