QUILL AND BOBBIN SUPPORTER.

SPECIFICATION forming part of Letters Patent No. 423,793, dated March 18, 1890.

Serial No. 315,476 (No model.)

To all whom it may concern:

lie itknown that I, ANDREW J. MILSTEAD, a citizen of the United States,,residing at Tallassee, in the county of Elmore and State of Alabama, have invented certain new and useful Improvements in Quill and Bobbin Supporters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specification.

My invention relates to devices for supporting bobbins or quills during the operation of spooling, and has for its object to simplify the construction andimprove the operation of such devices; and it consists in the improved construction, arrangement, and combination of parts hereinafter fully described, and afterward specifically pointed out in the claims. p

In the drawings forming part of this specification, Figure 1 is a view in side elevation, showing my improved supporter mounted upon its supporting-rail, showing in dotted lines the position the parts are made to assume when ready to insert the bobbin or quill. Fig. 2 is a longitudinal central section through the device; and Fig. 3 is a fragmentary View, partly broken away, showing how a spring may be substituted for the weight shown in Figs. 1 and 2.

Like letters of reference mark the same parts in all the figures.

Referring to the drawings by letters of reference, A is the rail upon which the supporter is mounted.

B B are the two parts of the frame or base of the supporter, each of which is longitudinally slotted, as at b b. A bolt C passes through both of said slots and the rail A and has on its lower end a suitable nut and washer. By turning up said nut the parts B B are secured to each other in any position to which they may be adjusted, and at a the same time the whole device is rigidly secured to the rail A.

The upright ends of the supporter are marked D D, each of which is formed with a head, as E E, which form bearings for the journals F F of the cups or conical. holders G G, in which the ends of the quill or bobbin H are supported. These journals are grooved circumferentially, as at ff, and the points of screws f f rest in said slots, thus serving toprevent the falling of the journals out of their bearing. 1 I

Suitable oiling-apertures are provided at 4 f The cups G G are lined with leather, rubber, or any other suitable substance, the purpose being to cause the cups to rotate with the quill or bobbin when the thread is being unwound and to prevent damage to the ends of the quill or bobbin by contact with the inner metallic surface of the cups.

- The upright D is hinged or pivoted at cl to the end of the portion B of the frame, and is provided with a suitable stop 01', to prevent it moving inward beyond a position of substantially a right angle to the frame or base B B. This upright is extended below the base and has secured to it and extending under the base an arm J, provided with perforations j, inwhich a weight K may be secured, the series of perforations being provided so that the pressure forward of the conical support G may be regulated by placing the weight nearer to or farther from the fulcrum cl. In Fig. 3 I show a modification of this weight and lever device, a spring L being substituted for the weight, the operation of which will be understood by an inspection of the drawings without further (IIQSOIlPlJlOIl. I am at present of the opinion, however, that the weight is to be preferred to the spring. The upright D is rigidly secured to or formed in one piece with the part B of the base and stands at substantially a right angle therewith.

The operation of my invention is as follows: The device being mounted upon the rail, as shown, the bobbin or quill is placed with the head in the movable cup-support and the support moved to the position shown in dotted lines, this carrying it farther away from the stationary head, so that the other end of the bobbin or quill may be dropped on the stationary head. The parts are -then IOC brought to the full-line position, in which the bobbin is unwound. I

The adjustment of the length of the base of the frame provides for the accommodation of bobbins or quills of differentlengths.

Having thus fully described my invention, what I claim herein as new and of my own invention, and desire to secure by Letters Patent of the United States, is as follows:

1. The herein-described quill and bobbin supporter, provided with a frame having a fixed cup-bearing at one end and a movable bearing at the other, said bearings being mounted on the frame, as set forth.

2. A quill and bobbin supporter having a cup-bearing at each end, both rotatable, one being journaled in arigid arm or upright and stantially as described.

3. A quill or bobbin supporter having a longitudinally adjustable frame provided with a rigid upright at one end and a pivoted moving upright at the other, two cup-bearings, one journaled in each ,of said ends, and a single fastening device which secures the frame to the beam and fixes its adj ustment as to length, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ANDREW J. MILSTEAD.
