SPECIFICATION forming part o1' Letters Patent No. 355,210, dated December 28, 1886.

Application filed August 1T, 1886. Serial No. 211,136. (No model.)

To @ZZ whom it may concern:

Beit known that we, WILLIAM H. RIVERS and EDGAR WRIGHT, both citizens of the declare that the following is a full, clear-,and

eXact description of the invention, which will enable others skilled in the art to which it appertains to make and use the sarne,reference being had to the accompanying drawings,

which form apart of this'spectcation, and inwhich- Figure l is a perspective View of so much of a spinning'niachine as is necessary to illustrate the application of this invention. Fig. 2 is aperspective view of the roller-beam having attached thereto a combined hinge and rest, also a combined hinge, rest, handle, and brace, each device being shown closed in full lines and open in dotted lines; and Fig. 3 is a vertical transverse section th rough the middle of the combined hinge, rest, handle, and brace.

Likeletters of reference indicate corresponding parts throughoutthe several Vfigures.

This `invention relates to an improvement in spinning-machines; and it consists in the iinproved construction and combination of parts vconstitutingsaidimprovement, as will be hereinafter fully set forth.

The object of this invention is to provide a ready and effective means for simultaneously raising all the guide-wire blocks of a ringspinning frame by tilting and automatically bracing the thread-board, to the front edge of which said blocks are hinged; also, at the same time, to provide for vertically adjusting said threadbOard. The means which are employed in accomplishing this object consist offtwo devices, one of which is an elaboration of the other.

The iirst device consists, as shown in the accompanying drawings, ofa hinge-leaf, A,which is adj ustably'secured to the roller-beam B by a screw-bolt, C, passed through a slot, D, in said hinge-leaf and a hole in the roller-beam.

From the front of thishingeleaf arest,E, pro# jects horizontally. The rest is formed of a rectangular frame, into the center portion of which fits one. end of the other hingeleaf, F,

when the hinge is closed. The leafF has one portion formed at right angles to lthe other, the portion fitting into the rest being wider than the other portion, and serving for attachment to the thread-board N. The narrower portion has the hinge-pintle passed through its end, and rests in the upper part of the slot in the hinge-leaf A when the hinge is closed. This rest aids in rigidly supporting the threadboard in its operative position,'and prevents undue strain upon the hinges of the same whenV it is lowered after changing the bobbins.

-The second device, which is the more important part of the invention, is produced throughtransforming the first by cutting away the front part of the rest E and extending the broad portion of the hinge-leafF into the handle G, which projects out in front of the guide- Wire blocks and their guide-wires. By means of this handle the thread-board can-be raised, and with it all the blocks M, which are separately secured to its front edge by means of hinges. The transformation also extends to the lower part of the other hinge-leaf, which is prolonged, and its slot closed at the bottom by the cross-piece H and spanned by. another cross-piece, l, near the junction of said leaf and the rest, said rest in its transformed shape consisting of the two arms J. The strengthening function of the broken-away part of the rest is supplied by the crosspiece I, which, together with the lower crosspiece, keeps the parts at the sides of the slot D from spreading apart. Then alever-brace, K, is added, provided with a notch in its lower edge, by which itis fulcrumed upon the crosspiece H. The

inner end of the lever-brace is shaped to engage a notch, L, formed in the outer angle between the handle and the inner end of the leaf F, and the outer end is weighted, so as to canse the upper end to readily fall into said notch immediately upon raising the thread-board. The lever holdsthe thread-board up tillthebobbinshavebeen changed. Then the weighted end of the lever is raised and the thread-board lowered into operative position.

`rlhese devices can be readily applied to any of the ordinary spinning machines Without drilling any new holes in the roller-beam, since the bolts C can be passed through the holes formed for the bolts which hold the old form IOL) of rests or braces under the thread-board. The

, slotsin said devices provide for their ready attachment to a beam, in which the old holes may be at variable distances from the upper edge thereof, and also for vertically adjusting the thread-board upon its beam.

Having thus 'fully described our invention, We clain1 1. rlhe combination, with the thread-board and roller-beam, of a slotted hinge-leaf provided With a rest projecting horizontally from its front and a hinge-leaf in Which the attaching portion is formed at right angles to the portion through which the hinge-pintle passes.

2. The combination of the thread-board and the roller-beam with the hingeleaf provided with a rest projecting horizontally from its front and a hinge-leaf in which the attaching portion is prolonged into ahandle and formed at right angles to the portion through which the hinge-pintle passes.

3. The combination, with the thread-board and roller-beam, of a slotted hinge-leaf provided with rests projecting horizontally from its front and a hinge-leaf in which the attaching portion is prolonged into a handle formed at right angles to the portion through which the hinge-pintle passes, the inner end of the handle portion iitting between the rests, and

t-he other portion fitting into the upper divis- 3o ion of'said slot.

4. The combination, with the thread-board and roller-beam, of a hin ge-leaf secured to said threadboard, a slotted hinge-leaf secured to the roller-beam, a single bolt passed through said slot, .and a lever-brace pivoted vin the lower end of the slot. Y

5. The combination, with a thread-board and roller-beam, of a hinge-leaf secured to said thread-board, a slotted hinge-leaf secured to said roller-beam and provided with a crosspiece at the lower end of the slot, and a weighted lever-brace provided with a notch in its under edge by which it is pivoted upon said crosspiece.

In testimony that we claim the foregoing as our own we have hereunto affixed our signatures in presence of two witnesses.
