SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 731,856, dated June 23, 1903.

Serial No. 117,561. (No model.)

To aZZ whom it may concern:

Be it known. that I, ELLIS L. OASTOR, a citi zen of the United States, residing at Reading, in the county of Be'rksand State of Pennsyl- Vania, have invented new and useful Im provements in Shuttles, of which the followingis a My invention relates to shuttles, and. more particularly to means for holding bobbins in shuttle-bodies, and its novelty, utility, and practical advantageswill be fullyunderstoodfi from the following description and claims: when taken in conjunction with the accompanying drawings, in which- Figure l is a plan view of a portion of a shuttle embodying -myimproved bobbinholder, the said holder being shown with a bobbin in proper position therein. a longitudinal section of the same with a por-. tion of the fixed jaw of the bobbin-holder broken away. Fig. 3 is a transverse section taken in the plane indicated by the broken line 3 3 extendingthrough Figs. 1 and 2. Fig. 4: is a transverse section taken in the plane indicated by the broken line 4 l-extending through Figs. 1 and 2, with a portion of the bobbin-head broken away; and Fig. 5comprises disconnectedperspective views of the jaws and other parts making up my improved bobbin-holder. I

Similar letters of reference designate corresponding parts in all of the several views of the drawings, referringto which- A is a shuttle-body, recessed at A in the usual manner to receive a bobbin B, having a circumferential groove (2 in its head I), and

t C is my improved bobbin-holder. This holder in the present and preferred embodiment of my invention comprises a fixed jaw D, a pivoted jaw E,.a retainer F for holding the jaw E against casual movement when said jaw is in its lower position and also when it is in its upper position, and a spring G, which backs the retainer'and tends to press the same forwardly. The jaw D is disposed transversely in the bobbin-receiving recess A of the shuttie-body at one end thereof andis crescent or C shaped, asbest shown in Fig. 5; It is provided at itsforward edge with an inwardlydirected flange c, which extends throughout the length of. said edge, so as to enter the groove a in the bobbin-head at the bottom Fig. 2-18 and sides of said head, and is also provided with a rearwardly-extending shank dof channel form in cross-section. This latter is arranged in a recess 6 in the body A between the bottom of said recess and horizontal fiangesfon the body, as best shown in Figs. 1, 3, and/l.

As best shown in Figs. 2 and 4, the jaw E of the bobbin-holder is curved in cross-section to conform to the head of the bobbin and is provided at its forward edge with an inwardly-directed flange g, designed to enter the groove a inthe bobbin-head at the upper side of said head. Said jaw E is also provided with a depending portion h, which is arranged in the shank d of the fixed jaw D and is pivotally connected to the shank and the shuttle-body bya transverse pintle z". The portion'h of the pivoted jaw terminates at its "rear" end in a rounded head j, which is disposed in the concave forward side of the retainer'F after the manner best shown in Fig. 2; The retainer is backed by the spring G and is preferably provided with a rearwardlyextending stem 70, arranged in the spring, as illustrated, The spring G exerts pressure in a forward direction against the retainer F and by so doing enables the retainer to securely hold the jaw E against casual. movement when the forward portion of said jaw is pulled upwardly and also when the forward The spring also assists in the downward moveter such movement is started.

When a bobbin is placed in the recess A of the shuttle-body A, so that the flange c of jaw D enters the groove 0, at the bottom and opposite sides of the bobbin-head, and the forward portion of the jaw E is pushed downwardly, so that its flange g enters the groove cat the upper side of the bobbin-head, it will be seen that the jaw E will be securely retained against casual movement in said po= sition, and in consequence the bobbin being engaged by the jaws D E at allsides will be securely clamped and held by the same. It will also be observed that the bobbin will be held firm-t. a, in such manner as to prevent movement thereof in the shuttle-body-which is highly desirable in weaving. To effect the removal of the bobbin from the shuttle-body,

portion of the jaw is pushed downwardly.

ment of the forward portion of the jaw E afan attendant has but to move the free end of the bobbin upwardly. When the bobbin is thus moved, the bobbin-head presses the jaw E up into its upper position, where it will be held by the retainer F, and the bobbin may then be readily withdrawn from the shuttlebody.

The fixed jaw D of my improvements is susceptible of being used alone in a spindleshuttle for the purpose of holding a bobbin, the spindle being provided on the jaw E in lieu of the curvedwand flanged portion or I otherwise mounted in the shuttle-body.

' parts, as such changes or modifications may be made in practice as fairly fall within the scope of my claims.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. In a shuttle, the combination of a body recessed to receive a bobbin, and a bobbinholder carried by the body, and comprising a crescent or C shaped jaw fixed transversely in the lower portion of the recess of the body,

and having a flanged forward'edge arranged to engage a'circumferential groove in a bobbin-head at the bottom and opposite sides of said head, a jaw pivoted at an intermediate point of its length and having a transversely curved and flanged forward portion, and a rounded head on its rear portion,and a springbacked retainer having a concave forward I side receiving said rounded head.

2. In a shuttle, the combination of a body recessed to receive a bobbin, and a bobbinholder carried by the body, and comprising the crescentor C shaped jaw fixed transversely in the lower portion of the recess of the body at one end thereof, and having the flanged forward edge, and also having the rearwardly-extending shank of channel form, the jaw having the forward transversely curved and flanged portion, and the depending portion pivoted in the shank of the fixed jaw, and also having the rounded head at the rear of said depending portion, the retainer receiving said head, and the spring backing said retainer.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ELLIS L. CASTOR.'
