Patented Nov. 26, 1929 ,urrs STATES PATENT OFFICE WASHINGTON L. HALL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO JAMES IBILLINGTON COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA SHUTTLE Application filed July 12, 1928. Serial No. 292,184. i

My invention relates to a novel construction in shuttles whereby the bobbin spindle is assembled in a novel manner with respect to the shuttle body so as to permit the easy and expeditious removal and replacement of bobbins.

My invention further relates to the novel construction of a shuttle having an adjustable, yieldably supported movable bobbin spindle and its adjuncts hereinafter described.

To the above ends my invention consists of a shuttle body having a deep recess at. one end thereof, a spring in said recess, a bolt engaging said spring, a bobbin spindle having a head on one end thereof, comprising a cam portion adapted to co-act with the head of said bolt, a pendant lug adapted to abut against a shoulder of said body, and means for pivotally mounting said spindle head within a bracket of novel construction.

My invention further consists of various other novel features of construction and advantage, hereinafter described and claimed.

For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my inventionis not limited to the precise arrangementand 0rganization of the instrumentalities.

In the accompanying drawings Figure 1, represents a fragmentary plan view of a shuttle and its adjuncts embodying my invention.

Figure 2, represents a longitudinal section on line 2-2 of Figure 1.

Figure 3, represents a transverse section on line 33 of Figure 2.

Figure 4, represents a plan view of a spinignates a shuttle body having the spindle 2,

split as at 3, to form a resilient grip and support for the bobbin (not shown). The spindle 2 is provided with therear head 4: having the rear cam face 5 and pendant lug 6.

The shuttle 1 is provided with the longitudi- 6O nally extending recess 7, in which is posi-. tioned the spring 8 encircling the bolt 9, the head 10 of which engages the outer end of said spring and forms a yieldable abutment for the cam face of said spindle head. 10

designates a brackethaving the rear upper lip 11 whichabuts'against the wall 12 (see Fig. 2)- said bracket being. provided with the arms 13, which comprise the outwardly curved portions 14 adapted to seat in come sponding recesses in the walls of the shuttle body, and the terminal inwardly deflected juxtaposed portions 15 which serve as a rear stop or rest for the rear end of the bobbin (not shown) when the latter is placed on the spindle. A bolt or pin passes transversely through the opening 17 in the spindle head 4 and through aligning holes in the walls of. the bracket 10 and the shuttle body, pivotally to secure said spindle in the position as will 30 be understood from Figures 2 and 3.

The top of the spindle head 4 is provided with the upper recess 21 one terminal edge of which is adapted to abut or bear against the outer front edge 20 of the bracket 10. when 5 the spin-dle is in its uppermost position as seen dotted in Fig. 2, said front edge thus serving as a stop to limit the upward movementof the'spindle and greatly adds to the life ofthe shuttle by eliminating the wear 9o and tear on the shuttle body were the'spindle 2 to abut against a wooden shoulder in said body in lieu of the metallic surface provided by the front edge 20 of the bracket 10, as will be understood from Figures 2, 4 and 5.

When it is desired to remove or replace a bobbin, the spindle 2 is turned upwardly through the upper opening 18 in the body of the shuttle 1, into the position shown in dotted lines in Fig. 2, the cam face 5 of the head 1, bearing against and sliding on the head of the bolt 9, which provides a resilient support to retain said spindle in any desired position. The lug 6 is adapted to abut against the shoulder 19 tolimit the downward movement of the spindle 1, and retain the latter.

in its normal or horizontal position. The in.- wardly deflected terminals of the arms 13 of the bracket 10 are disposed on either side of the bobbin (not shown) when the latter is in position on the spindle. It will thus be seen that the head 1O of the bolt 9 carrying the spring 8 constantly bears against the contiguous cam face 5 of the head 4 of the spindle, thereby constantly and yieldably exerting pressure thereon as will be best understood from Figure2.

It will thus be seen'from'the foregoing that owing to the tension of the spring 8 upon the head 10" of the bolt or pin 9 there is a constant pressure always exerted upon the cam face 5 and that said pressure coupled with the contact of the lug 6 of the wall 19 will tend to hold the spindle 2 at all times in its proper normal or horizontal position, as seen in Figures 1 and, 2. The resilient inturned juxtaposed terminals 15 form a resilient support or abutment on the end of the bobbin as is evident and when the spindle 2 is turned into the position seen dotted in the Figure 2 the contact of the walls of the seat or recess 21 with the metal edge serves to arrest the upward movement of the spring and the tension of the spring 8 temporarily locks the bracket having forwardly extended rectangular shaped horizontal spring arms arranged to seat in recesses in said shuttle body, a spindle, a rear head for said spindle provided with a pendant lug adapted to abut against a shoulder in said shuttle body, a cam surface formed on the rear portion of said spindle head arranged to abut against the head of said bolt, and means pivotally securing said spindle head to said bracket and to said shuttle body.. r 1 I WASHINGTON L.

parts in the position seen dotted in Figure 2.

l 'It will thus be seen that have devised a novel construction of a shuttle wherein the spindle is firmly, pivotally and yieldably supfurther; be seen that my novel construction is not only highly durable and efficient, but is also inexpensiveto produce.

,Havingthus described my invention what I claim as new and-desire to secure by Letters Patent, is

body having a recess therein, a spring. pressed In a device of the character stated, a shuttle bolt' having an outer headfdisposed within
