2 Claims.
' This invention appertains to newnand useful improvements in looms and more particularly to means for checking shuttles against rebound movements.
'An important object of the present invention is to provide means forstopping ashuttle in the proper position in a shuttle box in orderto preclude any rebound motion and in order that the shuttle always be uniformly-in position to be struck by the picker stick.
Another important object of the invention is to provide a rebound stopping device for loom shuttles which in use will serve to eliminate the necessity of a considerable number of adjustments that now take the time of loom fixers.
Still another important object of the invention is to provide a shuttle checker cooperating with the usual protector rod, which serves to carry the binder fingers, whereby in the event the usual spring of the protector rod becomes inoperative the improved means for checking the shuttle will also serve to set the conventional dagger.
Other objects and advantages of the invention will become apparent to the reader of the following description.
In the drawings:
Figure 1 is a fragmentary side elevational View showing portions of a conventional loom with the improvement applied.
Figure 2 is a fragmentary top plan view showing a shuttle box and the present invention associated therewith.
Figure 3 is a fragmentary elevational and sectional view showing a shuttle box in section and associated mechanism in conjunction with the present invention, the binder finger shown in shuttle holding position.
Figure 4 is an elevational and sectional view similar to that of Figure 3, but showing the lay moved away from the spring element of the present invention.
Figure 5 is a perspective view showing a protector rod, etc., in conjunction with the spring of the present invention.
Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes a loom frame to which the elements of the present invention generally referred to by numeral 6 are attached.
Numeral 1 generally refers to a lay on which are box structures at the ends thereof as shown in Figure 1 and generally referred to by numeral 8.
Each of these box structures'B comprises a box front 9 and a binder II], the box front: 9 having slotted lugs ll through which machine screws l2 are disposed and driven into. the-lay. By loosening and tightening these machine screws 1'2, suitable adjustment oflthebox front 9 can be attained.
As shown in Figures 1 and2, each box 8 h-as a picker stick is operative therein. Further ea'ch binder ID has a spring M for exerting" normalpressure thereon. vAs is conventional, the binder l0 which is flexible andanchored atone end -as at l5, has a belly l6, which the usual shuttle I! acts on when entering the box 8 to lift the usual dagger to an elevated position out of the path of the usual stop frog.
Now referring to additional details of the conventional machine, it can be seen in Figure 5, that numeral I9 denotes an elongated protector rod having laterally disposed foot portions 20, 20 at the ends thereof. On the foot portions 20 areadjustably secured fingers 2|, 2| which bear against the binder I0 as suggested clearly in Figures 3 and 4-. The rod [9 carries a dagger 22 which is cooperative with a frog 23 situated on the loom frame or some supporting structure.
As is understood, the lay 1 moves toward the right and left as illustrated in Figures 3 and 4. The present invention is associated with the rod l'fl.
In carrying out the present invention, an angle plate 24 is attached to the loom frame 5. This angle plate 24 has a slot 25 therein and a machine screw 26 is disposed through this slot and into a threaded opening in the frame 5. With this means the plate 24 can be easily adjusted. Rising from the outstanding portion of the angle plate 24 is an elongated spring 21 having a curved upper end portion, curved in the direction away from the adjacent foot portion 20 of the protector rod l9.
Referring again to Figure 5, it can be seen that spring means is associated with the protector rod IQ for normally maintaining the binder fingers 2| pressing against the binders 10. This spring means consists of an adjustable collar 28 and a spring 29 coiled about the rod l9 and anchored to some stationary structure as at 30.
It can now be seen that with the lay 1 moving toward the right in Figure 3, the near foot 20 will engage the upper curved end portion of the spring 21. However, just before this takes place and as the lay reaches in full extent of movement, the shuttle drives into the box. Al- II lost simultaneously the foot 20 shown in Figure 3 rides the curved upper end of the spring 21, rocking the protector shaft I9 and causing the fingers 2! to exert additional sudden pressure for but the slightest moment, just before the lay starts in the opposite direction. This actionserves to stop the shuttle as it reaches its fullest insertion in the box and serves to pre- "shuttles with the result that the full force and efiect of the picker sticks is not and, of course,
cannot be utilized when the shuttles ar improperly positioned in the boxes. However, with each shuttle stopped at its most eflicient position in the boxes a high percentage of loom disturbances will be eliminated.
Another advantage of the present invention resides in the fact that should the spring 29 become disrupted on the protector bar l9 and a shuttle not enter its box, obviously, action of the foot 20 against the spring 21 will act to push the binder l0 much farther into the box and upon the return movement of the lay and before the protector rod [9 and dagger 22 have had an opportunity to resume the position shown in Figures 3 and 4, the dagger will have struck the frog 23 to automatically stop the loom without the assistance of the spring 29.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is:
1. In combination with the rotatably mounted protector rod of a loom, and spring means tending to rotate the rod in one direction, a lateral protuberance on said rod, and a stationarily mounted member adapted to be struck by the protuberance and impart a sudden momentary increment of rotation to said rod in said one direction.
2. In a loom, a shuttle box including a, binder, a rotary protector rod provided with a binder finger and spring rotated in one direction to press said finger against the binder, a, lateral protuberance on the protector rod, and a stationarily mounted leaf spring against which the protuberance is adapted to strike, and be deflected to impart a sudden momentary increment of ro-, tation to said rod in said one direction and to exert additional pressure by said finger against said binder.
