AT TO RNEY United States Patent Otfice 3,426,809 Patented Feb. 11, 1969 3,426,809 LOOM BOX FRONT Furman S. Cox, Seneca, S.C., assignor to Deering Milliken Research Corporation, a corporation of Delaware Filed Nov. 14, 1966, Ser. No. 593,906 US. Cl. 139-183 1 Claim Int. Cl. D03d 49/54, 49/02 ABSTRACT OF THE DISCLOSURE A loom box front which has a hardened steel tip at the position where the shuttle enters the box front.
This invention relates generally to an improved loom and in particular to new and improved box fronts for loom shuttle boxes.
Prior to this invention right and left hand shuttle boxes on the loom have been damaged by engaging with the shuttle as it passes back and forth across the loom. If the shuttle is the least bit out of alignment it tended to strike the left and right hand box fronts, head on, causing damage to the box front as well as damage to the shuttle. Further, the leather which was attached to the inside of the shuttle boxes was being gouged and torn by the impact of the point of the shuttle resulting in considerable down time of the loom for repair and replacement of the leather lining for the shuttle boxes.
It is therefore an object of the invention to provide apparatus to reduce damage to the loom box front,
Another object of the invention is to provide apparatus to positively guide the shuttle as it enters the shuttle box so that it does not gouge the lining of the shuttle box.
It is a still further object of the invention to provide a new and improved box front for the loom which is not readily damaged by the shuttle.
Other objects and advantages of my invention will become apparent as the specification proceeds to describe the invention with reference to the accompanying drawings, in which:
FIGURE 1 is a top partially schematic view of a loom and FIGURE 2 is a blown-up perspective view of the left hand box front shown in FIGURE 1.
Looking now to the drawings and in particular to FIG- URE 1, the reference numeral represents a conventional loom equipped with the herein disclosed invention. In a conventional manner warp yarn 12 from a warp beam 14 is passed through the harnesses 16 and the reed 18 where it is woven into fabric by the passage of the shuttle 20 back and forth across the loom from left shuttle box 22 to the right shuttle box 24 and vice versa to interweave the warp yarns in controlled fashion. Reference numeral 26 schematically represents the picker sticks which supply the propelling force to the shuttle 20. From the reed 18 the woven fabric is taken up in conventional manner by the take-up roll 28.
The shuttle boxes 22 and 24 which hold the shuttle 20 between trips across the lay 30 are similar in function but different in construction due to the design of the loom. The box rears 32 of each of the boxes 22 and 24 have a leather strip not shown which is operably associated with the inner surface thereof to cooperate with the leather strips 34 and 36 mounted on the box fronts 38 and 40-, respectively, to absorb the shock of the shuttle as it moves into the box and to rapidly deaccelerate the speed of the shuttle. Prior to this invention when the path of travel of the shuttle 20 varied a small amount due to misalignment it tended to strike the strips 34 and 36 gouging out a portion thereof necessitating stopping of the loom to replace the strips. This resulted in an unnecessary expenditure for new strips, lost production time of the loom and expense of labor to repair the box fronts.
Looking now to FIGURES 1 and 2 and especially FIGURE 2 the new improved left hand box front 38 is shown. Prior to this improvement the leather strip 34 extended all around the nose portion 42 of the box front which was very susceptible to damage by the shuttle 20. To alleviate this situation a hardened steel contoured member 44 is welded or otherwise secured to the nose portion 42 of the box front 38 to provide a surface which will not only stand up under the impact of the shuttle but is elliptically rounded to guide the shuttle 20 into the shuttle box in proper position.
The herein described improved box front for the loom shuttle boxes provides many advantages over prior art devices. The improved box fronts have substantially reduced the necessity to stock a large supply of leather strips for replacement. Further, the increased service life of the leather strips provide a substantial cost saving since it is not now necessary to constantly replace damaged straps. Overshadowing these savings is a very substantial savings due to reduction in loom down time and reduction of the labor necessary to repair the loom.
While the apparatus disclosed and described herein constitutes preferred forms of the invention, it will be understood that the apparatus is capable of alteration not departing from the spirit of the invention and that all modifications of the apparatus that fall within the scope of the appended claim are intended to be included herein.
That which is claimed is:
1. A box front for a loom comprising: an elongated metallic member, a strip of leather attached to one side of said member and extending toward one end of said member and a hardened steel shock resistant member connected to said one end of said elongated metallic member, sai-d hardened steel member extending from said one end and contacting said strip of leather and having an outer surface contiguous with the outer surface of said leather strip.
