HO WA R D R I BOWMAN AT TO RN EY United States Patent C) 1 Claim ABSTRACT OF THE DISCLOSURE A loom box front which employs a roller means -at the entrance thereof to absorb the shock of the shuttle and to guide the shuttle into the shuttle box,
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 a still further object of the invention to provide a paratus to Ireduce 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.
I is .a still further object of the invention to provide a new land 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;
FIGURE 2 is a blown-up perspective View of the left hand box front shown in FIGURE 1; and
FIGURE 3 is a partial perspective view of the right hand box front shown in FIGURE 1.
Looking now to the drawings and in particular to FIG- URE l, the reference numerial represents a conventional loom equipped with the herein disclosed invention. In a conventional manner warp yarn 12 from warp beam 14 is passed through the harness 16 and the reeds 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 reeds 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 Irears 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 "ice 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 at FIGURES 1 and 3 the transfer bunter 54 for the filling bobbin in the shuttle 20 is secured to and under the right hand box front 24 and has a shaft 56 projecting upwardly therefrom at the end thereof with a roller 58 of nylon or other suitable material secured thereon by a nut 60. The roller 58 when contacted by the shuttle 20 will rotate in a clockwise direction to guide the shuttle into the shuttle box 24 and at the same time reduces the frictional force between the shuttle andthe box front encountered in the prior art devices.
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 strips. Overshadowing these savings is a very substantial savings due to reducing 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 invention that rfall within the scope of the appended claims are intended to be included herein.
That which is claimed is:
1. A loom having a warp beam with yarn thereon, take-up roll to roll up Woven fabric, means to weave said yarn into fabric between said Warp beam and said takeup r-oll, said means including 'a pair of shuttle boxes with one on one side of said loom and the other on the other side of said loom, said shuttle boxes each having a box front, the improvement comprising a transfer bunter connected to at least one of said box fronts, and roller means rotably connected to said transfer -bunter and projecting upwardly therefrom into the path of travel of a shuttle traveling across the loom to absorb the shock of the shuttle and to guide a shuttle into the shuttle box.
