ADJUSTABLE? SHUTTLE CHECK;
Application filedMarehBS, 1928. ser ai n ecsszs;
The present invention relates to improvements in-adjustable shuttle checks, andmore particularly it relates to an improved means 7 for adjusting the tension upon the binder.
It is an object of the invention to provide an improved adjustable tension device that will avoid the expense and nuisance entailed in present constructions.
The further object of theinvention is to cure present difiiculties by an inexpensive and simple form of tension device which will be adaptable to all existing types of shuttle boxes.
WVith the foregoing. and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto. i 1
In the drawings,wherein like symbols refer to like or corresponding parts'throughout the several views,
Figure 1 is a fragmentary perspective view showing a portion of a loom with a shuttle box and the improved tension device.
Figure 2 is a top plan view, with parts shown in section, of the binder and improved tension device apart from the shuttle box, I and on an enlarged scale.
Figure 3 is a side view of the improved tension lever alone.'
Referring more particularly to-the drawings, a shuttle box of conventional form is shown at 4 as having a number of cells in accordance with the usual practice; and 5 designates the rod by which the shuttle box is customarily shifted. 3
Each cell of the box is provided with a binder. For purposes of illustration, I have shown the binder 6 as pivoted at one end in ears 7 of the shuttle box,,the pivot pin being indicated at 8. This pivot pin passes through a cylindrical bearing 9 in the binder. The binder is provided with. anintermediate offset portion 10, to which is secured the guide serve to hold the lever up tothe coil spring 12. The arm of the lever 13, which'engages the coil spring 12,.is preferably longer than the arm which carries the set screw. A cylin- V drical or other bearing 16 inthe intermediate portion of the lever is adapted tofitbetween ears, 17 of the shuttle box, which are adjacent the ears 7 and are perforated to receive the pivot pin 18 by which the lever 18 is secured in place outwardly beyond and overlapping the binder 6. c The shuttle box 4 is shifted in the usual way, and the shuttles are operated in the customary manner by the picker staff. The shuttle having been driven across the race and into its cell of the shuttle box will encounter the binder, which. will check and hold-it until the next picker stick operation.
By turning the set screw 15, which abuts against the wall of the loom frame or shuttle box, the adjusting lever 13 may be shifted angularly about its fulcrum for the purpose e of increasing or decreasing the tension upon the coil spring 12,'and consequently, the tension upon the binder. A very delicate adjustment can be had with the set screw 15.
This minute adjustment is very important, as
it dispenses with the present practice in mills of bending the binder into shape, and re-adjusting and re-bending the binders as the shuttles wear smaller. This bending operation requires considerable time of skilled operatives and results in the final breaking of the binders from the repeated bending operations.
considerable saving in waste. The device will'also save the picker on account of the very minute adjustment possible with the set screw; and it will stop the kinks due to shuttles bouncing back. The invention will do away with the necessity forv hammering the binders, which results in the'breakage of shuttles and in many cases the excessive bending of the binders. Then, too, slamming with its attendant breakage and'the'jarring of the timing,the head motion and the'bearings, is avoided. In short, the invention will reduce loom breakage and proportionately increase production. I
It will be obvious that. many changes in v the construction, combination andarrangement of parts could be made, which could'be used without departing from the spirit of my ,Moreover, the 1mproved devlcewlll stop the fill1ngknock1ng off, which involves a invention, and I do not mean to limit the invention to such details, exeeptas particularly pointed out in the claims.
Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:
1. In a shuttle box having a binder, a lever fulcrumed intermediate its ends in the box beyond the binder, a pin carried by the binder for loosely engaging one end of the lever, a coil springwound about the pin, and engaging both the binder and the lever, andan adjustable set screw carried by the other end of the lever, andjtaking against the shuttle box for adjusting thespring tension upon the binder. I V
2. In shuttle box, a binder pivoted in the box, a lever pivoted close to the pivot point of said binder and extending along the binder to a point remote from the pivot point there of, resilientineans disposed between said,
binder and the remote end portion of the lever, and means for ad ustably moving said lever against the tension of said resilient means toward the binder.
3. In a shuttle box, a binder pivoted in the box, a tension lever also pivoted the box close to the pivot point of the binder and having arms extending in opposite direction 'lfrom' the lever pivot point, one or said arms extendlng along the binder to a point remote from the binder pivot point, a pin secured to the binder near the free end of said arm and extending outwardly from the binder and freely through said arm of the lever, a coil spring wound about said pin between the binder and lever arm, said lever having a second arm extending from the pivot pointthereof, and
means for acting on'said second arm to tend to move the first mentioned arm relatively to the pin toward the lnnder whereby to compress said spring.
, 4. In a shuttle box, a binder pivoted in the box, and having an intermediate oliset portion, a pin carried by said oliset portion and projecting outwardly from the binder, a lever iiulcrumed inthe shuttle box adjacent the "pivotal point of the binder and having a long and a short arm extendmg oppositely from the fulcrum pomt, said long arm extending along the binder to a point remote from its pivotal point, the free end of said long arnr being oll'set away from the binder opposite the offset portion oi the binder and freely receiving the end portion of said pin, titl pin being headed on the outer side of said long
