BOBBIN-HOLDER FOR SPOOLlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 258,567, dated May 30, 1882,

Application filed January 20, 1882.

To all whom it may concern:

Beit known that I, THOMAS C. ENTWISTLE, of Lowell, Massachusetts, have invented certain new and useful Improvements in Bobbin- Holders for Spoofing-Machines, of which the following is a specification.

The object I have in view in this invention is to produce a bobbin-holder which shall be simpler and less expensive and possess greater durability than those that are now generally used. The latter, so far as I am aware, are of complicated construction, which not only makes them expensive, but renders them liable to soon get out of order.

The device which I have devised consists of a simple holding-trough, closed at both ends, in which the bobbin lies, in combination with a hinged cap which closes the top ofthe trough, and is designed to rest upon the bobbin with a view to retaining it in place, and also to exerting upon it the requisite friction. To further the latter purpose, I combine with the hinged cap a weight,which is adjustablein such manner as to cause the cap to bear upon the bobbin more or less, as desired. This weight, however, although very convenient, is not a necessity, since in many cases the cap can in the first instance be made of the right weight to afford the needed friction on the bobbin.

In the drawings accompanying this specification, Figure 1 is a front elevation, and Fig. 2 is a side elevation, of the device. Fig. 3 is a sectional elevation of a spoofing-machine with my improved holders in place thereon.

A is the bobbin-holding trough, having both ends closed. Itis carried by a stand, B, (preferably cast in one with it,) by which the device is secured to the machine-frame. From the stand projects a bracket-like arm, 0, to which is hinged, at a, the cap D, that covers the trough. The cap covers the trough so as to rest upon the bobbin that lies loosely therein.

I have above intimated that the cap may be made in the first instance of such weight as to afford the needed friction on the bobbin; but for general purposes it is more convenient to combine with the cap a weight, E, mounted and adapted to slide on the arm or extension D of the cap on the opposite side of pivot a.

(No model.)

A set-screw, 1), holds the weight in any de sired position on the arm D, and in this way I can adjust with great nicety the pressure of the cap on the bobbin.

In Fig. 3 the holder is represented in place on the frame of a spoofing-machine. The mav chine is of well-known construction, and it is unnecessary to describe it further than to say that the spool-spindle is represented at c and the spoofing-guide at d. The thread or yarn passes out from the bobbin or between the front longitudinal lips of the trough and cap, and passes thence to the guide and spool in the customary way. The right-hand holder is shown closed and the left-hand holder open.

The whole device, excepting of course the adjustable weight, can be made up of but two castings, although it is preferred on some accounts to make the plates that close the trough ends separately from the trough itself, and to afterward secure them in place by proper means. It is cheap,'simple, very durable, and entirely effective.

I remark that in lieu of hinging the cap to the stand the cap manifestly may be rigidly fastened toor madein one withit. In this event 7 the trough would be hinged to the stand and would of course be weighted similarly to the cap in the first-described arrangement, so as to bear up against the cap with the requisite pressure. In either case,however, there would between the cap and the trough be a hingeconnection, whereby they would be enabled to co-operate in the manner hereinbefore de scribed.

In conclusion, I state that I am aware that self-adjusting or gravitating brakes or lips have before been applied to the bobbins or bobbin-holders of spoofing-machines for giving proper tension to threads oryarns that are being drawn off, and this I do not claim. 0

I am further aware thata bobbin having its spindle supported in bearings so as to be 'capable of revolving has been combined with a brake provided with an adjustable weight for the purpose of varying the friction or tension, 5 and this, also, I do not claim. Under my invention the bobbin-holder is atrough adapted to contain a bobbin loose within it, and to maintain that loose bobbin in a position who it may be acted on properly by the cap.

W'hat I claim as of my invention is-- 1. The bobbin-containing trough A, adapted to receive and support Without other bearings a bobbin loose within it, in combination with the cap D, these parts being united by a hingeconnection and adapted forjoint operation, as hereinbefore set forth.

2. lhe bobbin-containing trough A, adapted to receive and support without other bearings re a bobbin loose within it, in combination with the cap D, united therewith by a hinge connection, and the adjustable weight E, as hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 9th day of January, 1882.

THOMAS C. ENTWISTLE.
