SHUTTLE-BOBBIN HOLDER.

SpecificatiOno f Letters Patent.

Application filed May 17, 1913. Serial No. 768,264.

To all whom it may concern Be it known that I, ALBERT MANDEVILLE, a citizen of the United States, residing at Ware, in the county of Hampshire and State of Massachusetts, have invented a new and useful Improvement in Shuttle Bobbin Holders, of which the following is a specification.

This invention is an improvement in bobbin holding means for loom shuttles, and the object of the invention is to provide a simple and inexpensive device for the holding and positioning of the bobbin in the loom shuttle, preventing longitudinal movement of the bobbin in the shuttle and at the same time holding it in proper position relative to the top and bottom of the shuttle.

The invention further consists in the novel features of construction hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which, I have illustrated the holding device for holding one end of the bobbin.

In the drawings, Figure 1 is a side elevation, the position of the bobbin head being indicated by dotted lines. Fig. 2 is a perspective view of my improved bobbin holding means removed from engagement with the shuttle. Fig. 3 is a perspective view of the retention plate. Fig. 4 is a perspective view of the spring jaws.

In these drawings 1 represents an end member of a shuttle body the under side of which is recessed as indicated at 2 and upon the upper side, the body is recessed as indicated at 3, a transverse bore A leading from one recess to the other. Bobbin head holding jaws are formed of spring wire, said wire being bent to form a U-shaped frame 5, the bow portion of which is adapted to fit snugly in the recess 2 of the shuttle body 1. The side members of this frame slightly converge toward their free ends and their free end portions are bent upwardly or at right angles to the frame 5 as indicated at 6. These upturned end portions are substantiallv triangular in cross section thereby affording two adjacent fiat faces, thereby enabling these jaws to more securely grip the bobbin head. A retention plate is formed by bending a piece of metal to the form of a U-shaped frame having the upper and lower parallel faces 7 and 8, respectively both of which are longitudinally slotted as shown at 9, and said plates are connected by the bow portion of the frame said bow portion forming a connecting vertical plate 10. The lower plate 8 is notched upon oppositesides as shown at 11 and from said notches to its free outer end is enlarged or widened and fits snugly within the recess 2 of the shuttlebody 1. A suitable bolt 12 passes through the bore of the shuttle body and through the slots 9 of the holding plate and secures the parts together.

In assembling the parts together, the wire frame 5 rests upon the enlarged portion of the plate 8 while the jaws 6 extend in advance of and parallel to the plate 10. As the sides of the frame 5 converge normally lateral movement is provided for by said side members in the recess 2 to permit insere tion or removal of the bobbin head. A portion of the bobbin is shown in dotted lines and it will be readily understood that the head of the bobbin rests between and is grasped by the jaws 6 of the frame 1, said head bearing upon the plate 10 of the retention frame.

tive to the top and bottom of the shuttle and Patented Mar. 23, 1915. l

By means of this construction the bobbin can be properly positioned relaat the same time longitudinal movement of 1 the bobbin in the shuttle is prevented.

What I claim is 1. The combination with a shuttle body having a recess in its lower face, of a U- shaped spring wire member adapted to fit in said recess, said member having upright parallel jaws at its free end, and a U-shaped plate fitting over an end of said body, the bow portion of said plate resting parallel to the jaws of the spring frame and between said jaws and said shuttlebody.

2. The combination with an end portion of a shuttle, said portion having upper and lower recesses, a U-shaped frame, the upper and lower members of which fit respectively in said recesses, and a spring wire frame, the bow portion of which fits in the lower recess, the projecting portion of said spring frame being bent to form spring jaws parallel to and spaced apart from the bow por- 3. The combination with an end portion side members of the Wire frame having latof a shuttle having upper and lower recesses, eral play in said recess, as and for the pura U-shaped retaining plate having its side pose set forth.
