JOHN B. CLOUTIE R, OF SACO, MAINE, ASSIGNOR T0 CROMPTON 8t KNOWLES LQOM \VORKS, A CORPOB;ATION OF MASSACHUSETTS.

LOOM SHUTTLE-CHECK.

To all whom it may concern." 1 Be it known that I, JOHN 'B. CLoUTInn, a citizen. of the Dominion of Canada, residing at Saco, in the county of York and State of Maine, have invented certain new and use ful Improvements. in Loom Shuttle-Checks, of which the following is a specification.

My invention relates to a 100m shuttle check, and the object of my invention is to provide a shuttle check of improved con struction, and adapted to be combined with a stationary shuttle box of ordinary construction, with which the ordinary. shuttle binder is used.

common stud, independent'of the binder pivotal stud, and adjustable relative to each other, and located at the front. of the shuttle box, and near the outer end thereof. One

of the two levers has an engaging end ex tending in the path of the shuttle when it enters the shuttle box, to be engaged by the shuttle other of said levers has'an engaging end adapted to engage the's'hutt'er binder, to yieldingly press the'binder against the shuttle when it is in the box. There is an actuating spring intermediate the first mentioned lever, and in this instance an extension on the second mentioned lever, beyond the pivot point of said lever. mentioned lever has an extension thereon be yond its pivot point, which is adapted to engage with an adjustingscrew carried on the second mentioned lever, and the firstmentioned lever has an adjusting screw thereon, to regulate the inward movement of said lever, scribed.

I have shown in the drawing a stationary shuttle box at one end of the loom, with my improvements in shuttle check applied thereto.

1 Referring to the drawing:'-Figure 1 is a plan view of the right hand end "of a lay of a loom, with a stationary shuttle box thereon, with my improvements applied thereto; there is no shuttle in the box. Fig. 2 corresponds to Fig. 1, but shows the parts shown in. Fig. 1, when a shuttle entersthe shuttle box; a shuttle is shown in this figure, and, Fig. 3 is a front view ofthe Specification of Letters Patent. Application filed .Ta'nuary'ilz, 1911.

as it enters the shuttle box, and, the

all as will be hereinafter de-- hub 13 shuttle Patented Octlff), 1911. Serial No. 602,138.

arts shown in Fig. 1, looking in the direction of arrow a, same figure. i i In the accompanying drawing, 1 ,is the right hand end of a lay'of a 100m; carrying a stationary shuttle box or cell 2, for a shut tle 3, in the usual way.

' 4'15 a rock shaft at the front of the lay, carrying the protector finger 5, which is adapted to bear at its upper end against the I inner end of the shuttle binder 6, which is pivoted at its outer end on a stud 7 on the front side of the shuttle box. All of the above mentioned parts may 4 be of the usual and well known construction. My shuttle check consists preferably of two levers or arms pivotally mounted on a I I will now describe my improvements.

The front side of the stationary shuttle box is provided in this instance with. a lug or projection 2 which has adjustably secured thereon a bolt 8. The bolt 8 has pivotally mounted thereon the-yoke shaped boss or hub 9, see Fig. 3, of an arm or lever 9, which extends toward the outer end of the shuttle box. The free end of the armor lever 9 is bent inwardly, and extends in this instance around the pivot stud '2'. of the shuttle binder 6, and is adapted to engage with its engaging end 9, which end is preferably covered with leather -1() or other suitable material, the outer end of the shuttle 3, as shown in'Fig. 2, when the shuttle enters the shuttle box.

Ina downwardl extending'lug 9" on the arm 9 is an a justing screw 11, which turns in a threaded hole in said lug, and engages at its inner end the lower part of the stationary shuttle box 2, and acts to limit the inward movement of the lever' 9. The lever .9. is provided with a boss 2, thereon, see Fig.1, adapted to hold in a recessed portion a helically coiled expansion 'spring 12.

The second lever or arm 13 of my shuttle check has its hub 13 pivotally mounted .on the bolt 8. .Extending outwardly from the is'the extension 13" having a boss 13' thereon, into which the expansion spring 12 enters. The other extension 13, or main part of the lever 13, has the engaging end 13, adapted to engage with the binder 6, when the engaging end 9" of the lever 9 is moved outwardly when the shuttle enters the. shuttle box, in the direction indicated by the arrow in Fig. 1. On the main 105 part-.13 of the lever 13 is a boss 13, which art. When there is no .shuttlein the box,

the parts of the shuttle check mechanism will -normally be in the position shown in Fig. 1.1 When the shuttle enters the shuttle box, in'the direction of the arrow,'Fig. 1,

the forward or outer end of the shuttle will come incontact with the engaging end 9 of the'lever 9, and inovesaid lever outwardly,and through the action of the exoftwo levers or arms having a common piv-- pa'nsion spring l2,"move the engaging end 13 on the port'ion13 of the lever '13 yield-' ingly inwardly, to press against the binder 6, and force the binder against the side of the shuttle, to bind. the same. It will be understood that the details of construction of my improvements may be varied if desired.

. Having thus described my invention, what I 'claim as new, and desire to secure by Letters Patent is z- 1. In a 100m shuttle check, thecombination with the binder having a pivotal stud,

otal stud independent of the binder ivotal stud, and said levers being adjustab e. rela tive to each other, and located at the front of the shuttle'box, one of said'levers extending in the path of the shuttle when it enters the box, to be engaged by the shuttle, and the J other lever yieldingly pressed against the binder by the first mentioned lever, when the shuttle is in the box, to cause-the binder to press against the shuttle.

2. In a loom shuttle check, the combination with the binder having a pivotal stud,

- by thegfirst mentioned lever, when the shut-.

of two levers or arms having a common pivotal stud, independent of'the binder pivotal stud, and locatedat the-front of the shuttle box,- and one of said levers extending in the path of the shuttle when itcnters the box, to be engaged by the shuttle, andthe other lever yielding'ly pressed aga nst the binder tle is in the box, to cause thebinder to press against the shuttle.

" 3'. In' a loom shuttle check, the combination with the binder having a pivotal stud,

of two levers or arms, having a common pivotal stud, independent of the binder pivotal stud, said leverslocated at the front of theshuttle'box, and onset said levers hav:

other of said levers having one arm with an engaging end to engage the binder, and carrymg an ad ust1ng stud, to enga c said extension on the first mentioned ever, and

having a second arm on the opposite side of its fulcrum, and an actuating spring intermediate said second mentioned arm and the first mentioned lever, for the pur )ose stated.

4. In a loom shuttle check mechanism, the combination with the protector rod carrying the protector finger, and said finger to engage a shuttle binder, and said shuttle binder, of a shuttle check, comprising two separate levers, pivotally mounted, and having tl1e same fulcrum, one of said levers havinga curved arm extending around the fillcrumofthe binder, with 1ts engaging end in the path of the shuttle when it enters the shuttle box, and having an extension on the opposite side of itsfulcrum, and theother lever havin an arm with an engaging end to engage t- 1e binder, and carrying an ad- -justing screw to engage said extension on the first mentioned lever, and a, secondarm on the opposite side of its fulcrum, and a helically coiled expansion spring intermediate said second arm and'the first mentioned lever, for the purpose stated.

,- 5. In a loom shuttle check mechanism, the combination with the'pro'tector rod carrying 'the'protector finger, and said finger, to en gage a shuttle binder,- and said shuttle binder, of a shuttle check comprisingtwo separate levers, pivotally mounted, and having the same fulcrum, one of said levers having a curved arm extending around the fulcrum of the binder, with its engaging end in the path of the shuttle as it enters the shuttle box, and having an extension on the opposite side of its fulcrum, and carrying an adjusting screw' to limit the inward movement of said lever, and the other lever havingan arm with an engaging-end to engage the binder, and carrying an adjusting screw to engage said extension on the first mentioned lever, and a second arm on the opposite side of its fulcrum, and a helically coiled expansion spring intermediate said second arm and the first mentioned lever, for the'purpose stated.
