May 19, 1953 T. HINDLE LOOM TEMPLE Filed Sept. 28, 1949 Attorneys Patented May 19, 1953 l LOOMTEMPLE I Thomas Hindle', Blackburn, England Application September 28, 1949, serial No. 118,254

In Great Britain October 7, 1948 1 This invention relates to looms for weaving and more particularly to improvementsin means for supporting the temples on the loom front-rest. The main object of the invention is 'to provide improved means for supporting the temples, whereby these may be conveniently adjusted as requirements may necessitate in relation to the reeded width, to the level of the cloth at the fell andto the fell of the cloth, and then be rigidly secured so as effectively to resist the heavy contractional pull of the cloth during the weaving process.

Another object is to provide improved means whereby the temple and its holder-bar are promptly released and allowed to move forward quite freely,-so avoiding damage to the parts involved in the event of any object, such as a shuttle, being accidentally trapped between the temple and the advancing reed.

- A further object is to provide improved means whereby the temples, after these have been manipulated in the usual manner to engage the selvedges of the cloth, are forcibly drawn outwards towards the end of the loom until the fell of the cloth is extended to its full reeded width, after which the aforesaid temple supporting means are firmly secured so as to maintain such width adjustment.

According to the invention each temple is carried-at the end of a temple holder bar in which it can be adjusted vertically, the holder bar is adjustably mounted in a clamp stand so that the rear edge of the temple can be set closely adjacent to but in front of the fell line of the cloth and the clamp stand is slidably mounted on a longitudinal rail whereby the clamp stand and with it the holder bar and the temple can be set in anydesired position cor responding with the reeded width and locked in such position by set screws.

The invention is illustrated in and will be described with reference to the accompanying drawings in which:

' Fig. 1 is a partial front elevation showing the front-rest and temple supporting means at the leftend of a loom;

Fig. 2 is a plan corresponding to Fig. 1;

Fig. 3 is a vertical section on line 3-3 of Fig. 1; and shows'the temple in its normal position;

Fig. 3a is .a detail plan of the temple holderbar and its clamping-stud; I

Fig; 3b is a partial vertical section on line 311-- 31) of Fig. 1, and shows the pulling clamp;

Fig. 4 is a view similar to Fig. 3, but shows the templeand its holder-bar after these have been released and carried forward by an obstruction between the temple and the reed.

Referring to Figs. 1, 2 and 3, the front-rest of the loom consists 'of the horizontal flat section I and;.-the vertical flat section 'z, both of which 3 11 3 13 qcutedl ymb lt or. set crews to 5 Claims.

vides a fronterest of exceptionally strong and rigid construction,'such as is essential in the case of heavy and/ or wide looms. v As shown by dotted lines at C in Fig. 3, the woven'eloth moves forward from the fell, the position of which is indicated by linef-f-f, over the cambered top-edge of the temple rail sand downward over the rounded front edge of the' flat section I tothe usual take-up roller (not shown) The temple rail 3 is preferably grooved on both its front and rear vertical faces as shown at 3a, although the groove on the front face may be omitted, if desired, without serious detridle and engage the grooves in the temple rail 3 on which the 'clamp'stand is asliding fit, but

is clamped thereto by setscrews 5 in any desired positionaccording to the reeded width.

A cover-plate 1 is adjustablysecured by screws 40. tothe topofthe clamp stand 4." The underside of the cover-plate 1 and the topface of the .standlare grooved to providein 'combina-' tion a tapered slot corresponding to the taperedshank of a temple holder-bar B,which is a s11dable fit in the said slot.

The temple holder-bar 6 is rectangular in" crossfisection, the .vertical faces being parallel} as shown in Figs. 1 and-2. The underside is horizontaliand thetop face is tapered as shownat Gain Figs. 3 and 4. v

The .temple'8 may be of any known form, butis characterized by having a vertically projecting shank 9, by which it is supported. This shank 9- has a slidingfit in a vertical hole' l0 bored in the rearwardly projecting end of the holder-bar asshown in Fig. 3a; and is .clamped therein by'a clamp studi'lrfli z Y.

Before tightening the clamp-stud; H, the height; of the temple relative to the level of the cloth at g the fell is conveniently adjusted by means of a screw -l2,-whichscrews into the topend of the temple shank 9; while thescrew head bears on the Thollow cap: 13- which itself stands efterrsuitable.h ishtade end of the loom as shown in The cover-plate l is adjusted by means of its M screws 4a to permit the holder-bar to project to the extent necessary to place the rear'edg'e of the temple closely adjacent to, .but in frontoi, the fell line f). The screw 4a are not simply tightened down to clamp the holder-bar, but are adjusted so that the holder bar 6 complete with its temple 8, may be pushed into the desired position by hand, when the wedging action of the tapered profile of the holder bar 8 in the tapered slot formed in the clamp stand 4 and associated cover-plate l sufiices to retain the parts in the normal Weaving position shown in Fig. 3.

In the event of pressure being applied to'the temple as indicated by the arrow A in Fig. a, the wedge-shaped holder-bar is instantly and readily released and displaced in the forward direction as indicated by the arrow A which free sliding movement avoids damage to any of the parts involved.

After such releasing action, the temple may be restored to its working position, shown by Fig. 3, either by hand, or with the aid of a mallet applied to the front end of the temple holder-bar 6.

When commencing Weaving, either initially or after unweaving to eliminate a fault, the screws 5 are released and the stand s then moved in towards the centre of the loom to facilitate engagement of the temple rings with the cloth. To enable the temple and its supporting stand to be returned readily to its working position, a pulling screw M is temporarily screwed into the stand 4 and a pulling clamp 15, carrying the screw It is fitted on and clamped by its setscrews a to the temple rail 3, as shown in Figs. 1, 2 and 32). By the use of a. key to turn nut Man, the pulling screw I i is pulled through the stationary pulling-clamp, and consequently the stand 4- together with the holder-bar t and ternple 8 is forcibly pulled out (preferably simultaneously at each end of the loom) until the cloth Width at the fell is equal to and in alignment with the reeded Width, after which operation the screws 5 are again tightened to retain the stand 4 and the parts carried thereby, in such position.

If desired, the pulling-clamp and pulling screw may be retained permanently in situ as shown in Figs. 1 and 2.

The temple rail 3, stand 4, holder-bar 5 temple 8 with its characteristic vertical shank 9 and its means for height adjustment comprising the screw [2 and cap it, may be applied to looms in which the front-rest construction is diiferent from that hereinbefore described. For instance, the temple rail 3 may be made of greater depth and bolted or otherwise secured to the inner vertic-a1 face of a timber and/or metallic front rest. Alternatively, the temple rail 3 may be attached by welding or otherwise, to a plate or plates corresponding to the flat section I, and such plate or plates, bolted or otherwise secured to a timber and/or metallic front-rest.

I claim:

1. Means for supporting a temple on the front rest of a weaving loom comprising a temple, a clamp stand, and a temple holder bar rectangular in cross section, the vertical faces being parallel, the under surface being horizontal and the top surface inclined rearwardly and the clamp stand being formed with a correspondingly shaped tapered slot through which the holder bar passes whereby when the holder bar is moved rearwardly through the tapered slot it will be held sufficiently tightly to withstand any normal force tending to displace it during the normal running of the loom, but should any abnormal force be applied to the temple, such as caused by a shuttle being trapped between the temple and the advancing reed, the holder bar will be instantly released I and displaced in a'forward direction.

2. Means for supporting a temple on the front rest of a weaving loom comprising a temple, a clamp stand, and a temple holder bar rectangular in cross section, the vertical faces being parallel, the under surface being horizontal and the top surface inclined rearwardly and the clamp stand being formed in two parts with a tapered slot between them with means for adjusting the distance between the two parts to vary the depth of the tapered slot through which the holder bar passes whereby when the holder bar is moved rearwardly through the tapered slot it will be held sufiiciently tightly to withstand any normal force tending to displace it during the normal running of the loom, but should any abnormal force be applied to the temple, such as caused by a shuttle being trapped between the temple and the advancing reed, the holder bar will be instantly released and displaced in a forward direction.

3. Means for. supporting the temples on the front rest of a weaving loom, comprising the combination of a temple holder bar having a vertical. hole therein, a temple having a vertical shank slidably fitting the hole in the temple holderbar, means for clamping the shank of the temple in any desired position in the hole in the temple holder bar, a clamp stand in which the temple holder bar is mounted adjustably so that the rear edge of the temple can be set closely adjacent. to but in front of the fell line of the cloth being woven, a longitudinaltemple rail on which the clamp stand is slidably mounted to set the temple holder bar and the te ple in any desired position corresponding with the reeded width of the cloth, and means for locking the o stand at the desired position on the temple rail.

Means for supporting the temples on the front rest of a weaving loom as defined in claim 3, including means for adjusting the shank of the temple vertically in said vertical hole in the ple holder bar and thereby adjusting the ht of the temple.

5. Means for supporting the temples on the front rest of a weaving loom defined in claim 3, including means for moving the clamp stand on the temple rai to bring the temple into its normal working position.
