DETACHABLE WEAR MEMBER FOR TENSION DEVICES INVENTOQ ATTORN EY Patented Aug. 30, 1949 DETACHABLE WEAR MEMBER FOR TENSION DEVICES Joseph Turcotte, Lennoxville, Quebec, Canada,' assignor to Union Screen Plate Co. of Canada Ltd., Lennoxville, Quebec, Canada Application April 12, 1945, Serial No. 587,897

2 Claims.

The invention relates to detachable wear members for winding machine tensions and similar guides in the textile industry as described in the present specification and illustrated in the accompanying drawings that form a part of the same.

The invention consists essentially of the novel features of construction as pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of acceptable forms of the invention.

The objects of the invention are to salvage winding machine tensions, pigtails and other types of guides used in the textile industry for spinning, winding or twisting the thread or in similar processes, which would ordinarily be dis carded, by providing detachable wear members to cover the wearing surfaces over which the thread is drawn or otherwise comes in contact therewith; to devise a means whereby the wearing surfaces will be protected by detachable members, which in their turn, may be replaced when they become out by the thread, consequently eliminating the necessity of replacing the complete device; to save time and money in the industry by avoiding costly shut downs of the operating equipment due to replacements of parts containing the worn surfaces; and generally to provide auxiliary surface members that may be quickly and efliciently attached to the wearing surfaces that come in contact with the thread.

In the drawings:

Figure 1 is a perspective view of one type of Winding machine tensioning device to which the detachable wear members are applied.

Figure 2 is a side elevation of the wear member in the form of a clip.

Figure 3 is a plan view of the wear member as illustrated in Figure 2.

Figure 4 is a cross sectional view as taken on the lines l--4 in Figure 3.

Like numerals of reference indicate corresponding parts in the various figures.

In the textile industry considerable difficulty arises owing to the fact, that the thread which is drawn at a wash board tension often cuts into the wearing surface of the winding machine tension due to constant rubbing of the nylon, artifical silk thread or other type of thread which are noted to have a particularly severe cutting action.

In such cases it is necessary to close down the machine in order to replace the winder tension, thereby creating a wastage in material, as well as a drop in production due to the shut down, and it is therefore the purpose of this invention to avoid unnecessary length of time in the shutting down of the machine and to eliminate the necessity of completely changing thetension portion of the machine. a r

For the purpose of explanation, the following description and accompanying drawings describes and illustrates the detachable wear members as applied to a winding machine tension device of the washboard type, but it is of course understood that the wear members may be used on other types of winder tensions, pigtails and other guides which are used in the textile industry, for spinning, winding or twisting the thread or in similar processes and that these wear members may be made of any suitable material and in certain cases may be chemically treated so that they will be provided for wear and/or anti-corrosion purposes.

Referring to the drawings, the tension device as indicated by the numeral [0 consists of a plurality of surface bars I I over which the thread is drawn and these bars are provided with the curved edges l2 and are arranged in rows.

When these winding machine tension bars are in operation the thread will eventually cut into the surface thereof and therefore in place of replacing the entire winder tension the tension bars are provided with means of the surface clips 13 which closely follow the diameter of the bars and are provided with the longitudinal flanges I l and I5 and contain sufilcient resiliency that they will clamp and hold themselves fixedly onto the tension bars. The surface clips are also provided with recesses l6 and I! for engagement with the bosses l8 and IQ of the surface bars I I, so that there will be no danger of any slippage gf the clips after they engage with the tension ars.

In this way it will be noted that when one or more of the surface clips are cut by the thread or threads, all that is necessary to be done is to simply replace the worn clips with a new clip, there by avoiding lengthy delays which would ordinarily occur due to the stoppage of the machine using these winder tensions, furthermore eliminating the necessity of replacing the complete winder tension member with a new member.

It will therefore be seen from the above that it is unnecessary to close down the machine to replace the winding machine tension, but only to put one or more small parts in the form of these wear members and immediately putting the mastantially over a portion of said=surface-bars,- said surface bars having bosses on the surface" thereof,

and said surface clips having. recesses therein adapted for engagement with the bosses on said surface bars thus substantially holding said surface clips in engagemefit with said surface bars, and said surface clips being adapted to engage the thread passing over said tension member thus shielding said surface bars from the aforesaid thread. 4

2. In detachable wear members for tensions and similar guides in the textile industry, a tension member comprising a plurality of tension bars arranged in rows? each of said tension bars bein arcuate in cross section and having exterior bosses formed on the upper surface thereof, wear members in the form of clips having flanges integral therewith and adapted to clamp over said tension bars, said wear members having recesses therein adapted for engagement with the exterior bosses onsaid t'ension barsa'nd said wear; members being adaptedtdengage threads passing thereover thus shielding said tension bars.
