YARN-GUIDE SUPPORT FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 2 60,360, dated July 4, 1882. Application filed April 3, 1882. (No model.)

' To all whom it may camera:

Be it known that I, JOHN BIRKENHEAD, of Mansfield, in the county of Bristol, of the State of Massachusetts, have invented a new and useful Improvement in the Yarn-Guide Supports for Bing Spinning Frames; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawing, which exhibits a transverse section of the upper part of a ringspinning frame provided with my invention, the nature of which is defined in the claim hereinafter presented.

In practice it has been found objectionable to sustain the yarn-guide rail by vertical guides, and to apply to such rail or its supports one or more counterbalancing-springs, in manner as represented and described in Letters Patent N 0. 214,749, granted to me on April 29, 1879, for the friction attendant on the upward movement of the yaruguide and its supports has proved an obstacle to the starting thereof by the ring-rail acting against the arm extending from the supporting standard or standards of the yarn-guide, the result of such obstacle being a more or less uneven laying of the yarn on the bobbin. My present improvement is to avoid this difficulty, and in carrying it out I combine with the machineframe and each of the threadguide boards and its sustaining-standards, provided with adjustable arms to extend from it over the ring-rail, counterbalancing-springs and pivoted supporting-arms, the said arms being extended from the guide-rail standards across the machine-frame, and pivoted at their rear parts thereto, and supported by the counterbalancing-springs suspended from the creel. At its ends the thread-guide board may be furnished with friction-wheels to bear against the next adjacent vertical ends of the frame.

In the drawing a thread-guide is shown at b and its. carrying-board at B, the latter being supported near each of its ends by a standard, (3, from which there projects over the ring-rail E an arm, D, applied to the-standard so as to be adjustable vertically thereon. The lower part of the standard has a tubular projection, 0, provided with a set-screw, 61, such projection being to receive in its bore the supporting-arm G, which extends across the frame A in manneras shown, and is pivoted toit, as represented at H.

G is one of the supporting-bars of the opp'osite yarn-guide board. By means of the tubular projection c and its set-screw d the standard 0 may be fastened to the arm G, and be adjusted-thereon, so as to bring the guide-board B at its proper distance from the front portion, 6, of the frame A,'there being fixed to the said portioue a rest, f, to receive and sustain the yarn-guide board B when at its lowest position. a

Each yarn-guide board is to have to each of its supporting-standards 0 an arm, G, and there should be over such arm a counterbalancin g spiral spring, I, which, suspended from the creel K, should be connected with the arm by suitable means-as, forinstance, a cord, 9. The springs I, when the guide-board B is upon the rest or rests f, should operate with a lifting-power sufficient to or about to counterbalance the weight of the arms Gr, and the threadguides, the guide-board B, its standards O and their arms D, and the tubes 0 and their screws d, in order that on the ringrail rising and impinging against the arms 1) itshall meet withlittle, if any, resistance to effect the starting upward of the guide-board.

In the place of the spring I and cord g to each of the arms G, I sometimes make use of a cord going about a pulley, and fixed at one end to the arm and at the other to a weight, the arms and their adjuncts being counterbalanced by the weights. The hingepiu of the arm H, I usually arrange at an altitude which shall be in a horizontal plane situated midway of the rise of the lower face of the board B above the rest f.

I would remark that I do not herein claim the mode represented in my patent aforesaid of sustaining a yarn-guide board and counterbalancing-springs with it.

. What I claim as my present invention is as follows, viz:

The combination, with the frame of a ringspinning machine, and with each of its yarnguide boards and its supporting standards, of pivoted arms and counterbalancin g-sprin gs, arranged and applied substantially as set forth, the standards being provided with adjustable arms to extend from them to and over the ring-rail, as represented.

JOHN BIRKEN HEAD.
