ATTORNEY.
United States PatentO 3,405,741 FRONT FOR LOOM SHUTTLE BOX Clinton W. Hampson, South Hadley, Mass., assignor to Clinton Silk Mill, Inc., Holyoke, Mass. Filed Sept. 9, 1966, Ser. No. 578,330 1 Claim. (Cl. 139-483) ABSTRACT OF THE DISCLOSURE A binder for a shuttle boxof a loom of the flying shuttle type comprising: a main body portion having a curved heel portion and a curved nose portion; a frictional covering layer of leather fixed to said heel portion and to said main body portion and terminating at said nose portion; a combination wear resistant and cushioning means disposed exteriorly of and fixed to the curve of said nose portion for absorping the impact of the flying shuttle on the binder; said combination wear resistant and cushioning means comprising an epoxy layer fixed to said nose pontion and a metal wear plate fixed to said epoxy layer and said nose portion; reinforcing strips spaced along the upper surface of said covering layer; and said reinforcing strips being epoxy and being disposed at an angle to the longitudinal axis of the binder.
My invention relates to a loom shuttle box binder and more particularly to a reinforced binder or plate for a shuttle box of a loom of the flying shuttle type.
In looms of this type, wherein the binder of the shuttle box is subjected to repeated and high impacts from a shuttle which is travelling at high speed, excessive binder wear and breakage is frequently experienced.
A primary object of the invention is to provide a binder having a novel wear surface capable of absorbing the initial impacts of the shuttle, thereby greatly prolonging the life of the binder.
Another object is to provide a binder of the type de-I scribed which is adapted for use in flying shuttle type looms of conventional construction.
These and other objects and incidental ends and advantages will be apparent from a reading of the following detailed specification and claim, taken in conjunction with the accompanying drawings, wherein:
FIG. 1 is a top plan view of a loom shuttle box binder or box front plate incorporating the novel features of the invention;
FIG. 2 is a side elevational view thereof; and
FIG. 3 is a cross-sectional view taken on the line 33 of FIG. 1 and showing, in phantom, a flying shuttle in engagement with the binder or box front plate.
It should first be noted that the binder or box front plate shown in the drawing and hereinafter described in detail, is associated with either one of the shuttle boxes of a conventional flying shuttle type loom having front and rear shuttle boxes for guiding a flying shuttle in its travel back and forth relative to the lay of the loom, the shuttle being hurled at high speed by a picker mechanism and striking, with especially high force, the nose of the binder or plate of the shuttle box.
Since the above-described loom is conventional in all respects, other than in the construction of the shuttle box hinder or plate, a detailed discussion of the latter only will be had hereinafter.
The shuttle box binder or plate is generally indicated by and is of the usual elongate rectangular construction having a main body portion 12 preferably, but not necessarily, formed from metal and having depending bosses 14, 14 at its opposite ends to permit the resilient mount- 7 3,405,741 Patented Oct. 15, 1968 ing thereof relative to the shuttle box of the loom, all as is known.
Here following for purposes of orientation, the right end of binder 10 as seen in the drawing will be referred to as the nose portion and the left end as the heel portion.
As is conventional, the upper surface of main body portion 12 is plane throughout and is provided, over a portion of its length, with a cover-ing layer 16 of leather or similar frictional-type material which acts in the manner of a brake .to slow the speed of the flying shuttle, the covering material being fixed to the upper surface of the main body portion by any suitable means, as by bolting or an adhesive or the like, not shown.
The heel portion of the main body portion curves downwardly and inwardly as at 18, the covering material following said curve and having its inner or rearward end fixed to the lower surface of the main body portion as by a screw or bolt 20.
The curved heel portion offers a smoothly inclined surface to the shuttle on its retrograde stroke, thereby lessening the shock of impact when the shuttle strikes the binder.
The nose portion of the main body port-ion curves downwardly as at 21 and is provided with a layer of high impact material 22, in the nature of epoxy or the like, bonded to the main body portion in any suitable manner.
Superposed upon the layer of epoxy is a wear plate 24 preferably formed from a nonresilient metal in the nature of stainless steel or the like and fixed to the main body portion as by bolts or screws 26 which extend downwardly through the wear plate, epoxy and main body portion and have nuts 28 threaded thereon or by weldments.
The point of jointure between wear plate 24 and covering material 16 is reinforced by a thin strip 30 of epoxy or like material, said point of jointure additionally being angularly disposed relative to the longitudinal central axis of the binder, indicated by the imaginary line x-x in FIG.
1, thereby to better withstand the wear and tear of the shuttle passing thereover.
Feeler slot 40 communicates with a registering slot 42 provided in the main body portion, the slots 40 and 42 being provided to permit the insention of the loom feeler mechanism (not shown) for determining if the yarn supply is exhausted, all as is conventional and well-known in the art.
As previously stated, the nose portion of the binder takes the main brunt of the shock of impact when it is struck by the shuttle, indicated by S and shown in phantom in FIG. 3.
The combination of the metal wear plate and epoxy provided on the nose portion serve to cushion the binder from this shock, thereby greatly prolonging its life.
Similarly, the angularly disposed epoxy reinforcing strips, being disposed at points of potential weakness also strengthen the covering material.
Since these reinforcing strips are angularly disposed, they do not demonstrate the tendency to gra the shuttle as it travels thereover, as would happen if they were normal to the binder axis, thereby assuring smoother loom operation.
I claim:
1. A binder for a shuttle box of a loom of the flying shuttle type comprising:
(a) a main body port-ion having a curved heel portion and a curved nose portion;
'(b) a frictional covering layer of leather fixed to said heel portion and to said main body portion and terminating at said nose portion; (c) a combination wear resistant and cushioning means, disposed exteriorly of and fixed to the curve of said nose portion for absorbing the impact of the flying shuttle on the binder; (d) said combination Wear resistant and cushioning means comprising an epoxy layer fixed to said nose portion and a metal Wear plate fixed to said epoxy layer and said nose portion; (e) reinforcing strips spaced along the upper surface of said covering layer; and (f) said reinforcing strips being epoxy and being disposed at an angle to the longitudinal axis of the binder.
