SLIDING HEDDLE FOR COMPOSITE LOOMS 2 Sheets-Sheet 2 Filed May 18, 1948 Patented Nov. 1, 1949 UNITED STATES PATENT OFFICE SLIDING HEDDLE FOR COMPOSITE LOOMS Sylvester Theodore Bryson, J12, Wilmington, Del.
Application May 18, 1948, Serial No. 27,789
3 Claims.
This invention relates to an improved sliding heddle for composite looms of the type embodied in Patent No. 2,364,276 issued December 5, 1944, for Composite loom.
In composite looms which are designed for weaving a tubular fabric about a hose or other tubular member there is provided a battery and a plurality of heddles arranged circumferentially about the axis of the battery. The heddles which have heretofore been in use on the machine embodied in Patent No. 2,364,276 wear out very quickly, becoming loose in their guides and the yarn guide tubes on the heddles are hard to replace. It is, therefore, an object of this invention to provide a heddle which will resist wear, can be properly lubricated, and the guide tube and roller pin can be easily and quickly replaced.
Another object of this invention is to provide a heddle of this kind which can be used as a replacement for the heddles in the composite loom, supra, so that the useful period of the heddles will be very greatly increased and the repair periods for the looms will be reduced in number and also shortened.
To the foregoing objects, and others which may hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically referred to and illustrated in the accompanying drawings, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention as claimed.
In the drawings:
Figure 1 is a fragmentary side elevation of a battery for a composite loom having'a sliding heddle, constructed according to an embodiment of this invention mounted thereon.
Figure 2 is a detailed side elevation partly broken away and in section of one of the heddles.
Figure 3 is a plan view of the heddle.
Figure 4 is a sectional view taken substantially on the line 4-4 of Figure 1.
Referring to the drawings, the numeral I designates generally a battery for a composite loom which is of the type embodied in Patent No. 2,364,276, supra. This battery includes a plurality of circumferentially spaced apart heddles, generally designated as H, which are slidingly engaged in guides l2. The guides l2 are constructed in the form of complementary elongated guide bars l3 and M which are formed with confronting lengthwise channels I5 and I6, respectively. A sliding heddle, generally designated as IT, is engaged between each pair of 2 guide bars I3 and I4 and the heddle I1 is constructed in the form of an elongated flat bar l8 which slidingly engages between the confronting inner sides of the guide bars l3 and Id.
The bar I8 is provided with a plurality of spaced transversely extending openings I9 within which balls 26 are loosely mounted. The balls 2|] project beyond the opposite sides of the bar I8 and movably engage in the confronting channels or grooves l5 and Hi as shown in Figure 4. The bar |8 adjacent the inner end thereof has secured thereto and extending from one edge thereof a roller carrying pin 2|. The pin 2| is formed with a reduced shank 22 which engages in an opening 23 and preferably the opening or bore 23 communicates with a counterbore 24 within which the inner end of the pin 2| is adapted to engage. The opposite end of the shank 22 is preferably upset as at 25 so that this pin 2| will be firmly secured within the bar l8. An elongated tubular yarn guide 26 extends from the same edge of the bar l8 as the roller carrying pin 2| and engages in an opening 21 which is formed through the bar I8. The tubular member 26 is tightly disposed in the opening 27 and the tubular member 26 is upset as at 28 so that this tubular member or yarn guide will be firmly secured in the bar l8 and may also be driven from the bar l8 after the tubular member 26 becomes worn to a point necessitating replacement thereof. The bar H3 is also formed with a pair of lengthwise extending slots 29 which not only provide for reducing the weight of the bar l8 but also provide lubricant reservoirs within which lubricant may be disposed so that the anti-friction balls 2!] and the confronting inner sides of the guide members l3 and I4 may be constantly lubricated.
By providing a heddle as hereinbefore described the heddle member will last for an indefinite period whereas the life of the heddle members shown in Patent No. 2,364,276 have a relatively short useful period. Furthermore, when either the roller carrying pin or the yarn guide tube become unduly worn these members may be driven from the heddle bar and replaced.
I claim:
1. In a composite loom having pairs of confronting channeled heddle guides, a heddle adapted to slidably engage between said guides, said heddle comprising an elongated flat bar, a roller carrying pin fixed to said bar adjacent one end thereof, a tubular yarn guide fixed to said bar adjacent the opposite end thereof, and a plurality of anti-friction members carried by said bar and projecting from the opposite sides thereof for engagement in the channels of said guides.
2. In a composite loom having pairs of confronting channeled heddle guides, at heddle adapted to slidably engage between said guides, said heddle comprising an elongated flat bar, a roller carrying pin fixed to said bar adjacent one end thereof, a tubular yarn guide fixed to said bar adjacent the opposite end thereof, and a plurality of anti-friction members carried by said bar and :projecting from the opposite sides thereof for engagement in the channels Of said guides, said bar being formed with at least one elongated opening constituting a lubricant reservoir.
3. In a composite loom having pairs of confronting channeled heddle guides, a heddle adapted to slidably engage between said guides, said heddle comprising an elongated flat bar slidably engaging between a pair of said guides, a
roller carrying pin projecting from one edge of said bar adjacent one end thereof, a tubular yarn guide carried by the opposite end of said bar and projecting from said one edge, said bar having a plurality of openings transversely therethrough, and an anti-friction ball in each opening projecting from opposite sides of said bar and engaging in the channels of said guides.
