SHUTTLE-CHECKING MEANS FOR LOOMS. v

SPECIFICATION forming part of Letters Patent No. 692,835, dated February 1 1, 190 2.

Application filed October 3, 1901. Serial No. 77,347. (No model.)

To all whom it may concern:

Be it known that I, CLARE H. DRAPER, a citizen of the United States, and a resident of I-Iopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Shuttle-Checking Means for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object the production of novel, simple, and effective shuttle-checking means for looms whereby the shuttle entering the shuttle-box will be gradually brought to a stop at the proper point,

avoiding a sudden or'abrupt checking of the shuttle, and thereby reducing the wear and tear thereupon. I

Various novel features of my invention will be hereinafter described, and particularly pointed out in the following claims.

Figure 1 is a top or plan view of one end of the lay of a loom, a shuttle-box thereon, and shuttle-checking means embodying one form of my invention. Fig. 2 is a rear elevation of the apparatus shown in Fig. 1; and Fig. 3 is a plan view of the binder and its supports, showing the binder in two positions.

Referring to the drawings, the lay A, longitudinally slotted at a, Fig. 1, forthe stafi of the usual picker P, the shuttle-box, comprising a front wall or plate 1), top or cover plate 17, secured at its outer end to an upright headed stud b on the lay and at its inner end attached to the lay-sword A and the protector mechanism may be and are all of substantially usual or well-known construction, the protector-shaft 19, mounted on the lay, the upturned finger 19, fast on the shaft, and the spring S to press the upper end of the finger toward the front of the lay being shown in Fig. 2. The cover-plate has at its inner end at the point of attachment to the lay-sword a depending web b from which are rearwardly extended two ears 12 b (best shown in Fig. 2,) which support an upright fulcrum-stud c. A short link or radius-bar c is fnlcrumed at its rear end on this stud, the opposite end being shown as bifurcated to present parallel branches 2 2,between which enters the reduced inner end 01 of the binder Y d pivotally connected to the link by a pin 0. The outer end of the binder is longitudinally slotted, as at d, to embrace loosely a loose sleeve 10 on the stud b (see Fig. 3,) so that the binder may move longitudinally relati vely to said stud and may also rock in a lateral plane about such stud as a fulcrum. The binder maybe made of any suitable material, and I have found a close-grained Wood to be very satisfactory for the purpose, the front or impact face of the binder having a swell d and between the swell and the outer end ofthe binder the inner face is concaved, as at 01 (See Fig. 3.)

The finger p bears against the rear face of the binder'near its inner end, as clearly shown in Figs. 1 and 2, and normally presses the binder into the shuttle-box,'with the swell in the shuttle'path, the free end of the link c at such time bearing against the upright end 25 of the web b of the cover-plate. (See dotted lines, Fig. l.)

When the shuttle enters the box, its shoulder engages the swell of the binder and moves the latter laterally against the stress of the spring S, the binder swinging about the stud b as a fulcrum, while at the same time the binder is moved longitudinally by and with the shuttle from the position shown in Fig. 1

and in dotted lines, Fig. 3, toward the fullline position shown in "the latter figure, the slot 61 permitting such longitudinal movement and guiding the outer end of the binder,

the latter thus actingcontinuously on the shuttle to retard its movement.

The link n forms, with the inner end of 1 the binder, a toggle-like connection with the fixed fulcrum-stud c of the link and directs or governs the movement of the inner end of the binder, the toggle connection straightening or becoming set as the shuttle reachesits proper position in the box.

It will be noted that while the full binderpressure acts upon the shuttle to check its progress, practically from the entrance of the latter in the box until the shuttle is stopped,

the rubbing action between shuttle and binder is reduced to a considerable extent'by the longitudinal movement of the binder with sition in the box the binder will have been moved into such position that the concave portion (Z of the impact-face of the binder will be in the path of the shoulder of the shuttle, acting as a stop therefor. \Vhen the shuttle is thrown from the box, the binder will move longitudinally therewith, rendering the exit of the shuttle easier than it would be otherwise, the action of the binder-spring acting to reduce the pressure on the shuttle as soon as it is started, and as the shuttle leaves the box the binder resumes its normal position. (Shown in Fig. 1.)

By my invention the motion of the incoming shuttle is gradually and easily checked without any injurious shock to shuttle or contained filling-carrier, the binder and shuttle being in substantially continuous contact at some point from the instant of impact to full stoppage ot' the shuttle, and the wear and tear upon the shuttle are very materially reduced, while the force required to throw the shuttle is less by virtue of the movement of the binder with the shuttle.

My invention is not restricted to the pre cise construction and arrangement herein shown and described, as the same may be varied or modified by those skilled in the art without departing from the spirit and scope of the invention.

Having fully described my invention, what I claim as newand desire to secure by Letters Patent, is-- 1. A shuttle-box and a spring-controlled binder longitudinally and bodily movable by and in the direction of movement of the shuttle.

2. A shuttle-box, a spring-controlled binder longitudinally movable by and in the direction of movement of the incoming shuttle, and means to throw the outer end of the binder into the shuttle-path upon such longitudinal movement of said binder.

3. Ashuttle-box,aspring-controlledbinder, a fulcrum for and relatively to which the outer end of said binder may rock laterally, and also move longitudinally, by or through impact of the incoming shuttle, and a fixedly- 5. Ashu'ttle-box, aspring-contro1led binder having a swell portion normally in the path of the incoming shuttle, and meansto sustain the binder to permit longitudinal and lateral movement thereof by the incoming shuttle.

6. Ashuttle-box,aspring-controlledbinder having a swell and a concave portion between the swell and its outer end, and means to throw the concave portion of the binder into the path of the sh Little-shoulder by or through impact of the entering shuttle with the binder;

7. Ashuttle-box,abinder-slotted atits outer end, a fixed stud to enter the slot, a swinging link having a fixed fulcrum and pivotally connected with the inner end of the binder, and means to normally maintain the binder in the shuttle-path, the binder being longitudinally movable and also adapted to swing laterally upon the fixed stud as a fulcrum.

8. Ashuttle-box, a spring-controlled, longitudinally-movable binder having a swell normally in the shuttle-path, and a toggle connection for the inner end of the hinder, the entering shuttle engaging the binder and moving the same longitudinally to straighten said toggle connection and also moving the binder laterally against its con trolling sprin g.

9. A shuttle-box and a spring-controlled binder longitudinally and bodily movable by and in the direction of movement of the incoming shuttle, and means to maintain substantially continuous contact between the shuttle and binder from the instant of impact to full stoppage of the shuttle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
