SHUTTLE BINDER Box Filed Jul-y 15, 1948 Patented Feb. 28, 1950 UNITED STATES .PATIENT OFFICE y SHUTTLE BINDER Box' William R. Taylor, Jr., cleveland Heights, ohio Application July 13, 194s., serialNo. 38,500
3 claims.
This invention relates -to improvements in shuttle binder boxes, and has to do primarily with a spring has been stressed by the entrance of the shuttle into the binder box. The holding spring then functions to reinforce the action of the conventional spring and to limit the further move-l ment of the pivoted side bar.
One of the objects of the `inventionis the provision of means for improving the action of the binder box of a loom by theprovision of an auxiliary holding spring or yieldable stop for the swinging side bar of the box.
Another object is the provision of means for adjustably mounting the holding spring so that it will become effective at the desired angle of swing of the side bar.
Still another object is the provision of clamping means for maintaining the mounting means of the holding spring rigid in its adjusted position.
Other objects and features of novelty will appear as I proceed with the description of that embodiment of the invention which, for the purposes of the present application, I have illustrated in the accompanying drawing, in which Fig. 1 is a fragmental plan View of one end of a loom lay embodying the invention.
Fig. 2 is a fragmental side elevational view of the same.
Fig. 3 is a cross-sectional view taken substantially on the line 3 3 of Fig. 2, but showing the parts on a somewhat enlarged scale, and
Fig. 4 is an elevational view looking in the direction of arrow 4, Fig. 3.
In the drawing the lay for a Draper loom is illustrated at I 6. One end only is shown, it being understood that the illustrated parts will be substantially duplicated at the other end of the lay. A slot II is formed in the lay to accommodate the picker stick I2 in its swing back and forth.
The binder box comprises a fixed side bar I3 secured to the lay by means of screws I4 or the like. It may be -faced with leather or other friction material I5. At both ends of the lay on the side opposite the fixed side bar I3 end blocks I6, one of which is shown in the drawing, are suitably attached to the lay. These blocks serve as supports for a fixed bar I1 which may be attached to the blocks by screws I8 or the like.
At each end of the lay a pivoted side bar I9 is oscillatably mounted on a pin 20 which extends downwardly through the bar I1, through a hole in the pivoted side bar I9 and into an aligned hole in the lay. Washers v2I may be "inter-posed lbetween the bar I9 and the iixed bar I1 ion the one hand and between the bar I9 and the lay I9 on the other hand. Bar I9, like bar I3, is yfaced `with leather or other friction mathe form of a leaf spring 2-3 :attached to block IS by screws 24 or the like. The function of the spring 23- of course is to resist outward swinging fmovement of the pivoted side bar I9 and thereby :setup 'friction vbetween the faced inner surface of the bar and the shuttle, which isillustrated vin the ,drawingat S.
Supported on the `iixed bar I 1 opposite a selectved point along the .length of the pivoted bar I9 .I :mount Aan auxiliary spring 25 which I term 28 and a sheet metal housing having a top 29, a
y The top 29 of the housing is provided with a round opening 34, through which the screw 33 may be inserted and through which a screwdriver blade may be inserted for tightening down the screw. In the back wall 30 of the housing I form a round hole 35 which merges with a smaller semicylindrical hole 36. 31 is an adjusting screw having a head 38 and a collar 39 spaced from the head a distance slightly greater than the thickness of Wall 30. In assembly the screw 31 may be inserted through the hole l35, the collar 39 being of less diameter than hole 35. The shank of the screw between head 38 and collar 39 is then permitted to rest in the semicircular hole 36 in which it has a rotatable bearing. Body member 26, 21 is drilled and tapped to provide a threaded opening 40 which cooperates with the threads on the screw 31. Turning the screw 31 one way orthe other causes the body member 26, 21 to slide in the bracket transversely of the fixed bar I1. A bolt 42 extends through registering holes in the housing side walls 3| and block 28.
This bolt and the side walls together constitute a clamp by means of which the body member 26, 21 may be gripped securely in any adjusted position. Block 28 is somewhat narrower than the body member 26, 21 and consequently compressive force exerted by the bolt 42 is free to act upon the body member 26, 21.
In the operation of a loom embodying the invention the spring 23 functions in the conventional manner during 'the greater part of the checking action exerted upon the shuttle, that is to say it causes the pivoted side bar i9 to press against the shuttle frictionally. As the line or point of contact between the shuttle and the bar I9 approaches the pivot 2U, swinging the bar I9 outwardly, the spring 23 is flexed more and more and its effect becomes stronger and stronger. A retarding effect is also exerted by the head 45 of the picker stick, the outboard movement of the latter being checked by any suitable picker stick checking means. 1f the inertia of the outwardly moving shuttle is not checked in such a way as to cause it to diminish gradually to zero at the farthest outboard point of the shuttle travel, it may bounce away from the picker stick head 45, which would interfere with the desired application of power to the shuttle on the return stroke.
The holding spring 26 of the present invention reinforces the action of spring 23' after the pivoted side bar I9 has swung outwardly to a predetermined extent, and brings the shuttle to a smooth stop. Since the transverse position of spring 25 is adjustable by very small increments through the operation of screw 31 the point in the cycle at which the spring takes eect can be controlled to a nicety. Of course when adjustments are to be made the bolt 42 is first loosened to relieve the clamping eiect upon the body member 26, 21, the adjustment is made, and as soon as it is determined by trial to be correct the nut on the bolt 42 is tightened, thereby causing the side walls 3| of the housing to grip the body member 26, 21 rmly and provide a rigid mounting for the spring 25.
Having thus described my invention, I claim:
1. In a loom, a lay, a xed bar running the length of the lay spaced above one side thereof, a binder box having a side bar mounted at its outer end on a pivot extending between said fixed bar and said lay, a spring arranged to exert inward pressure on said side bar for checking the outboard travel of the shuttle, a bracket mounted on said fixed bar near the free end of said pivoted side bar, and a holding spring extending downwardly from said bracket spaced outwardly from said pivoted bar in the inactive position of the latter and adapted to ycheck the final outward movement thereof.
2. A loom as defined in claim 1, wherein said bracket comprises adjustable means for holding said holding spring spaced at variable distances outwardly of said pivoted bar.
3. A loom as defined in claim 2, wherein said holding spring is formed rigid with a body member which is slidable transversely of said bracket, and wherein said bracket comprises a clamp for gripping the sides oi said body member in any of its adjusted positions.
