HHHHIIIHH 31a/venta@ aia am Patented June 24, 1930 UNETED WILLIAM H. IBAHAN, F GREENVILLE, SOUTH CARLINA y BOBBIN SUPPORT Application filed` July 6,

In certain types of bobbin changing looms, of which the Northrop and Stafford looms are representative, a spring actuated bobbin support is provided to coact with a guide to direct the bobbins from the hopper to the shuttle, when the bobbin transferring' arm is actuated. It frequently happens that the bobbin is not delivered to 'the shuttle and lodges beneath the bobbin support, thereby causing delay and veXation, all of which it is the intention of the present invention to obviate.

In the drawings hereto attached Figure 1 is a fragmentary view of a bobbin changing loom illustrative of the invention.

Figure 2 is an enlarged view of the improved bobbin support, the pintle therefor and associated parts.

Figure 3 is a perspective view of the bobbin support.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The loom illustrated is of well known construction and comprises a hopper 1, al bobbin carrier 2, guide 8 for directingrthe bobbins from the carrier to the shuttle et, and chute 5 for directing the empty bobbin displaced from the shuttle into a suitable receptacle.

' The bobbin transferrer 6 and pintle 7 are likewise well known parts of the type of loom indicated.

The present invention relates particularly to the bobbin support which is pivotally mounted upon the pintle 7 and cooperates with the guide 3 to direct the bobbins 8 during the transfer from the hopper to the shuttle. The bobbin support comprises a sleeve 9 and an arm 10, the sleeve receiving the pintle 7 upon which the support is pivotally mounted. A coil spring 11 mounted upon the outer end of the pintle 7 coacts with the support to normally hold the arm in elevated position, as shown by the full lines in Figure 1. The outer end of the arm 10 is curved downwardly, as indicated at 12, to form a guard to enter the shuttle 4 with the bobbin, as indicated moet clearly 1927. serial ivo. eoasze.

by the dotted linesin Figure l, so'as to prevent the bobbin from clearingthe arm 10 until theempty bobbin has been displaced from the shuttle, thereby preventing any possibility of the bobbin getting beneath the arm 10, `should the latter return to normal position without proper delivery of thefbobbin to the shuttle and displacement of the empty bobbin, by the full bobbin which has been transferred from'the hopper to the 50 shuttle.

Upon actuation of the transferrer to effect delivery of a full bobbin 8 from the hopper to the shuttle, the bobbin support moves with the bobbin and does not release the bobbin until the empty bobbin has been displaced from the shuttle. Should the transferrer vreturn to normal position withoutv effecting delivery of the full bobbin the latter is likewise returned to the hopper 'by the bobbin supportvas it assumes a normal position, thereby preventing the bobbin from lodging beneath the bobbin support, and causing trouble and necessitating` stopping of the loom to eii'ect readjustment of the parts. 75

It should be noted that the bobbin support is formed from a strip of resilient metal bent intermediate its length to form the eye 9 and the end portions of the strip extend from the eye in contacting relation to each other to form the arm /10. The arm is normally held in the position shown in full lines in Figure 1 by the finger 11 extending from'the inner end of the spring 11 but since this finger is not engaged about the arm, the portions of the resilient strip forming the arm are free to be forced away from each other. Therefore, if the bobbin support should get hung up instead of breaking the loom or battery, the lay comes back and the 9o battery jams, causing the arm to open and the support slides off the pintle transversely thereof.

Having thus described the invention, I claim:

1. In a loom structure, a intle, a bobbin support pivotally mounted on said pintle and being formed from a stri of resilient material folded intermediate its length to form a pintle-receiving eye and having its Wl end portions extending radially from Vthe eye in face to face engagement with each other to form a flat arm, the said end portions being movable away from each other to open the eye along one side whereby the support may slide out of engagement with the pintle, and a spring coiled about said pintle and having one end anchored to the pintle and its other end provided with a finger extending beneath said arm in free contacting engagement therewith to yieldably hold the arm in a raised position, the ends of the strip being bent transversely to form a lip extending downwardly at the outer end of the arm and adapted to enter a shuttle and bear flat against a wall of the shuttle when the support is swung downwardly about a pintle received in its eye.

2. In a loom structure, a pintle, a bobbin support pivotally mounted upon said pintle and being formed from a strip of resilient material folded intermediate its length to form a pintlereceiving eye and having its end portionsextending radially from the eye in face to face engagement with each other to form a flat arm, the said end portions being movable away from each other to open the eye along one side whereby the support may slide out of engagement with the pintle, and a spring coiled about said pintle and having one end anchored to the pintle and its other end provided with a iinger extending beneath said arm in free contacting engagement therewith to yieldably hold the arm in a raised position.

In testimony whereof I aHiX my signature.
