JAMES PEARSON, OF CENTRAL FALLS, RHODE ISLAND.

BOBBIN-HOLDER.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed April 1'7I 1907- Serial No. 368-641.

To all whom it may concern:

Be it known that I, .TAMEs PEARSON, a citizen of the United States of America, and a resident of Central Falls, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Bobbin-Holders, .of which the following is a specification.

In a pending application for patent filed by me in the United States Patent Office, Serial No. 299,828, I have illustrated and' described an improved bobbin-holding device adapted to be employed or associated with spooling, doubling, warping and other analogous machines.

My present invention also relates to bobbin-holders of the class referred to, and it consists in certain novel improvements in the construction and arrangement of the members, thereby increasing its efficiency and adaptability, the device at the same time being extremely simple and inexpensive, all as hereinafter set forth and claimed.

In the accompanying drawings, Figure l is a top plan view of my improved bobbin-holder showing the parts or elements thereof in the normal position, the bobbins being omitted. A Fig. 2 is a transverse sectional view taken on line 2 2 of Fig. 1. Fig. 3 is a longitudinal sectional view taken on line 3 3 of Fig. 1. In Figs. 2 and 3 the positioned bobbins are indicated by dotted lines. Fig. 4 is a side elevation of the front frame member, in enlarged scale, showing the swinging guide member in the normal operative position. Fig. 5 is an end elevation of the same, viewed from the left. Fig. 6 is a similar view showing the opposite or right end, and Fig. 7 is a plan view corresponding with Fig. 4, the guide, however, being represented in the temporarily retracted or unlocked position preliminary to placing the loaded bobbins in the holder or removing the empty ones from it.

The following is a more detailed description of my improved bobbin-holder device A, arranged to be detachably secured to any suitable base or board m. In practice the base has a number of the holders disposed thereon in alinement with one another.

The main or body portion a constituting the holder proper is or may be made of a single piece of sheet stock. I prefer to use a strip of sheet tin for the purpose and having each longitudinal edge reversely bent upon itself to form a narrow strengthening rib (1 having a well-rounded surface (1*. See Fig. 2. The member a is corrugated transversely to form a plurality of parallel horizontal V-shaped grooves a, the beveled sides a of which'constitute the seats for freely supporting the yarn-carrying bobbin. The vertical sides or ends a of the body member terminate each in a fiat base 01 having a hole therein adapted to freely receive a holding-down screw a. In order to further stiffen the body part a tie t is soldered to the underside of the seats, the same extending longitudinally of the device and also uniting the ends a as clearlysho'wn in Figs. 2 and 3. 1

At the front and rear sides of the body member and at a suitable distance therefrom are located the fixed up right frame members b and b, respectively; each being bent at right angles to form a foot b through which suitable holding-down screws pass. The screw-holes of one or both said feet may be elongated or slotted, as indicated at b, so that the frames may be readily positioned toward or from the respective sides of the body a, thus rendering the holder adjustable tobobbins varying in length. The upper part of the rear frame I) is provided with an inwardly facing longitudinally extending horizontal fixed guard or protector e. As drawn the latter consists of a single piece of wire, its ends being bent and soldered to the adjacent side of the frame. This guard member is positioned so that when in use its underside just clears the upper or adjacent part of the bobbin lying thereunder. That is to say, the bobbin when loaded with yarn will lie contiguous to the guard and when empty will obviously lie further away from it. In any case, however, the relation of the fixed guard e and the movable or locking-guard f (about to be described) to the body a are such that the bobbin cannot become accidentally unseated or separated from the holder even though the latter should be inverted. The said front frame b is provided with a guard member f mounted to swing in ears 1" and r secured to the outer face of the frame, the construction being more clearly represented in Figs. 4 to 7. The two arms 0 and c of the guard are somewhat resilient and have their lower ends bent inwardly and in alinement to form journals in said ears r and 1, respectively. The guard bar proper when in normal use extends horizontally over and parallel with the frame 1), its position and relation to the enlarged or base end of the bobbin being substantially as before described with respect to the guard e and the smaller end of the bobbin. The outer end of ear 1* is cut away to form a stop or shoulder sfor limiting the rearward movement of the guard, see Fig. 7, also the dotted lines in Fig. 5. The other car, r has a vertical notch or groove 3 communicating with and extending at right angles to the axis of the journals bearing, the upper outer corner of the adjacent wall being rounded or cam-shaped, as indicated at s. As thus devised the arm 0 automatically springs into said notch upon swinging the guard upwardly to the normal position, thereby practically locking it in place. See Figs. 4 and 6. A comparatively light pressure applied to the bar f, see arrow as Fig. 6, is sufficient to force the guard rearwardly, the lower end of the yielding arm 0 at the same time, by reason of its frictional contact with the cam 8 sliding outwardly from the notch thereby unlocking the guard and permitting it to be swung to the normal inoperative position (see Fig. '7') the fellow arm, 0, then resting upon the stop s. i

The manner of operation of my improved bobbinholder is substantially as follows: The front guard or latch f is first swung rearwardly to the full open position, after which the attendant readily places a filled bobbin, as h, in each of the self-positioning V-shaped troughs or grooves a of the body a, the smaller ends of the bobbins passing under the stationary guard-bar e and being arrested say by contact with the adjacent surface of the rear frame I); the opposite or larger ends of the bobbins at the same time lying contiguous to the inner surface of the front frame I). The guard f is now swung up-' wardly to its limit or until the arm 0 springs into the vertical recess 8 thereby locking the guard in the normal operative position, the guard-bar then extending over and being in close proximity to the heads of the bobbins, substantially as represented in Fig. 2, etc. The several threads are then conducted to the windingmachine to unwind them in a well-known way. As the unwinding process is continued the bobbins gradually descend in the respective troughs until the entire load is drawn off. The dotted circle to, Fig. 3, indicates an empty bobbin resting in the lower part of the holders seat.

While the drawings represent my improved holder as being constructed and arranged for seating three bobbins thereinI do not desire to thus restrict its capacity as obviously it may be devised to hold a greater or less numb er of bobbins.

I claim as my invention 1. As an improved article of manufacture a bobbin holder of the character described. the same comprising a suitably mounted body member having open seats for supporting bobbins therein, front and rear frame members for limiting the endwise play of the bobbins, fixed and movable guards extending in horizontal planes and adapted when in use to lie above and transversely of the respective end portions of the bobbins, and means 'operatively connected with said movable guard member for maintaining it both in the operative and inoperative positions.

2. In a bobbin-holder of the character described, the

combination with a base, and a body member a secured thereto provided with a plurality of open parallel V-shaped seats for supporting bobbins therein, of stationary independent front and rear laterally separated vertical frames extending longitudinally of and disposed with respect to said body member, a fixed guard e secured to the rear frame, a swinging guard f pivoted to said front frame, and means for automatically locking it in the normal operative position.

3. In a device of the character described provided with a suitably mounted bobbin-supporting body a. and front and rear stationary frames adjustably positioned with respect to said body, a swinging resilient guard pivoted in one of said frames, a stop for limiting the rearward movement of the guard, and a recess into which a member of the guard is adapted to spring so as to lock it in the normal operative position to prevent the bobbins from becoming accidentally unseated.
