July 27, 1943. G. c. TARTE PROTECTOR MECHANISM FOR LOOMS Filed April 29, 1942 mll bc-aring 3|) and this bearing is rigidly attached to the lay by a bolt 30. The other end of the spring is preferably straight as shown at 3| and is adapted. for insertion within a selected opening k32, formed in a flange 33 formed upon a" collar Arranged upon the outer sides of the ,swordsA II and extending to the front side of the lay are daggers 31, rigidly secured tothe protector-rod sections IQ. These daggers are adapted toengage with sliding frogs 38.

sleeve 2| will pass the end I 9 of the end protector-rod section I 6 to the left. This is rendered These frogs may be A employed to actuate the kick-off leverV or brake f devices or both. The frogs 38may be of the typ shown in Patent 1,322,605. y In the operation of the loom,l the lay I.0.,is

`moved back and forth "in theusual manner andv the shuttle travelslongitudinally of the lay and enters the shuttleiboxes at the ends of its stroke.

When the shuttle enters either shuttle box thel laywill start on its forward stroke and complete the forward stroke.V The shuttle willthen hold thebinder I4 in the outer position and the nger 26 will be pressed outwardlyand theiprotectorrod I5 will be turned in opposition to its spring 21, whereby both daggers 31 will beY raised sothat they will not engage the sliding frogs. However, should the yshuttle not enter either shuttle box,

lthe'binder would then not move outwardly and` the `iingerZE would remain in theinner position dueto the turning movement of. the binder shaft I5"caused by thespring 21 and the daggers 31 would, remain lowered and. would engage the sliding frogs 38 which would stop theaction vof th`e1ay.' Y Q v` ,It frequently happens that theprotector-rod breaks or becomes injured whereby the same must beremoved for replacement or repair. An irnportant feature of the presentinvention is the forming ofthe protector-rod in the outer endl protector-rod sections vand the intermediate protector-rod section. rIf either `end protector-rod section isbroken lor damaged, the set screws' 22 and V23 ar'eloosened and the adjacent sleeve 2| is slid-backfupon the intermediate lprotector-rod section I1 thus disconnecting the coupling-sleeve 2| from the end protector-rod` section IB.V Then the .bearing I 8 is removed from thev vsword by un-A screwing the single bolt I8 and this permits of. the'r'el'noval of the `end protector-rod section I6 without disturbingV the other lgend protector-rod section I6 or the intermediate.protector-rod sectionI1.. It is obvious that either end protectorrod-.section may` be removedrin this manner, re-

plaoed, and again rigidly connected with the intermediate protector-rod section-I1.- Should the intermediate protector-rod. .section i right so that its left end is further spaced from' they inner end I9 of the' end; 'protector-rod section, ISto the left and the'.v intermediate protector-.rodsection |,1` is Lnow angularly adjusted so that its left free "end"4 and the *left` coupling- ."iil

vpossible by the fact that there is considerable clearance between lthe walls ofthe bearing 30 and the protector-rod section I1 and there is also considerable clearance between the wall of the coupling-sleeve 2| and the protector-rod seclerally from its-position. Further, if it should be desired to remove or replace the spring .21 it will not be necessary to remove the intermediate protector-rod. section I1 or the end protector-rod sections I6. To accomplish this the set screws 22 and 23 of the coupling sleeve 2| to the right are.unscrewed and the coupling sleevel 2| to the rightis then slid inwardly upon the intermediate protector-rod section I1.L The right end of the protector-rods'ection I1 is now shifted laterally so that the coupling-sleeve 2| will clear the adjacent 'right end protector-rod section IS `and maybe slid off of theright endv of thev intermediate protector-rod section I1. The collar 34 may now be removed in ar similar` manner and then thespring 21-` By a reverse operation the springrand collar 34 are returned to the intermediate protector-rod section, the couplingsleeve 2| to the right again placed thereon, after which `the'intermediate protector-rod section I1 isbroughtinto alignment withv the right end protector-rod section I6 and the right couplingsleeve again clamped to these parts by manipulation of the set screws 22 and 23. ate protector-rod* section is somewhat resilient and maybe ilexedforveiecting these operations and thereis some playin the vbearing 35|..y

It is to be understood that the form of my inv vention herewith shown and .described is to be taken as` a preferredexample of the same and thatvarious changes in the shape, size, and arrangement of parts may be resorted `'to without departing from the spirit of my invention `or the n scope ofthe subjoined claims.
