TEMPLE ROLL Carl D. Brown,

Draper Corporation, poration of Maine Application March 10,

lv Claims.

The present invention pertains to temple rolls for loom temples and has more particular reference to the character and construction of the fabric-engaging surface of such rolls.

Loom temples commonly include a head hav ing one or more rotatable fabric engaging rolls which extend inwardly, widthwise of the cloth, from the cloth selvage. The cloth is pressed against the rolls and the surface of the latter is constructed and arranged to hold the cloth taut, widthwise, as it is woven. The present invention applies particularly to such temple rolls wherein the surface thereof is adapted to hold the cloth by friction, as distinguished from the pin-studded rolls commonly used on relatively coarse cloth.

In prior constructions, the friction type of temple roll was formed from or covered with a suitable resilient fabric-gripping material such as rubber, synthetic rubber or cork. Such materials have a high coeicient of friction with cloth and are therefore effective in holding the cloth taut. However, the resilient materials that are available for the purpose are not very eifective in withstanding the wearing action of the cloth and the useful life of prior temple rolls using said materials is comparatively short. The said wearing action is particularly severe at or near the selvage end of the temple roll, and is also found at the opposite or inner end of 'the roll, but is comparatively slight at the central portion of the roll. Thus, the temple rolls that are discarded as being worn out are badly worn at one or both ends and the center portions are still serviceable.

An object of the present invention is to provide a temple roll of the friction type having its central portion of a resilient fabric-gripping material, for holding the cloth, and its selvage end portion constructed and arranged to effectively 40 resist wear without detracting from the gripping qualities of the central portion, whereby the useful life of the temple roll is materially increased.

The aforementioned and other objects of the invention are accomplished in the construction illustrated on the accompanying drawing, of which:

Fig. 1 is a plan View of a temple operatively positioned with relation to the cloth;

Fig. 2 is a fragmentary plan view of the same temple with the cap thereof broken away to eX- pose the preferred embodiment of my improved temple rolls therein;

Fig. 3 is a detail view of one of said temple rolls detached from the temple; and

Fig. 4 is a longitudinal sectional View of the temple roll of Fig. 3.

The temple shown on the drawing includes a stand or housing l which is adapted to be fixed to a loom frame (not shown) and a bar 2 which is slidably mounted in the housing. The bar 2 is positioned adjacent and substantially parallel to the selvage S of the cloth C and has a laterally extending head forA receiving the cloth. This head may comprise a pod 3 and cap il for receiving my improved temple rolls, the temple eX- cept for such rolls being of usual construction.

The pod 3 and cap 4 constitute a housing for two parallel temple rolls 5, 5 which housing has the usual opening to permit the cloth to feed forwardly through the temple head in contact with the temple rolls. The rolls 5, 5 are rotatably mounted on the usual pins (not shown) which are supported by the cap 4. The cloth C, in the particular temple shown, passes between the pod 3 and the bottom of the temple rolls, the shape of the pod being such as to hold the cloth in contact with the rolls.

The temple rolls 5 are of the friction type in that they grip or hold the cloth by friction only. Each such temple roll comprises a roll body which is generally cylindrical in shape. In the preferred embodiment, the temple roll 5 consists of a wood core 6 having fabric-engaging covering thereon. This covering consists of a central portion 1 of suitableresilient fabric-gripping material such as synthetic rubber, and end portions 8 and 9 of vulcanized ber or other relatively hard wear-resisting material. The covering eX- tends from end to end of the core 6 except that the latter is provided at its inner end with a projecting enlargement or head I which engages the inner end of the portion 9 and prevents the covering from being pulled off the core.

The end of the temple roll 5 on which portion 8 is situated, which is the end close to the bar 2, is the outer or selvage end of the roll. The selvage end of the roll is, of course, engaged by the selvage S of the cloth, which may be under more tension than the main body of the cloth. This added tension, together with the contraction of the cloth in passing forwardly off the rolls, and possibly other factors, produces a wearing action which is particularly severe adjacent the selvage end of the roll. It is also found that, at least under some conditions, a similar severe wearing action occurs at the opposite or inner end of the temple roll.

The central portion 'l of the roll covering may be formed from a tube of synthetic rubber of sucient length to cover substantially more than half the length of the core 6. The external periphery of the portion 1, which contacts the cloth C, may be provided with suitable projections adapted to better grip the cloth. To this end, the portion 1 may be grooved as shown to provide projecting ribs Il. I iind that the cloth holding properties of the central portion of the roll are not materially aiTected by the character or properties of the end portions of the roll. Therefore, by making the said central or gripping portion of proper length, the roll as a whole can have sufficient grip to hold the cloth even if the end portions exert no holding action on the cloth. I am thus able to make the end portions of the rolls of a hard wear-resisting material, which materials have a comparatively low coeiiicient of friction with cloth.

The inner end portion 9 consists of a short tube of hard vulcanized ber which is positioned on the core 6 between the head l'and the inner end of the central portion 1. This end portion 9 is slightly smaller in diameter than the central portion 1, to allow the latter to be compressed by pressure of the cloth. The particular portion 9 shown is smooth, as well as being hard, and it therefore exerts little grip on the cloth. Nevertheless, the presence of such end portion on the roll prevents the aforementioned rapid wearing of the end of the temple roll.

The selvage end portion 8 is likewise formed from a tube of vulcanized ber positioned on the core 6, to prevent wear at the selvage end of the roll. This end portion may be constructed to have some cloth holding properties. To this end,

the portion 8 may be tapered, as shown, the

inclined cloth-engaging surface thus formed offering some resistance to Widthwise contraction of the cloth.

It will be apparent that temple rolls constructed in accordance with the present invention will hold the cloth reasonably well, .and will last several times as long as prior temple rolls having a resilient covering from end to end thereof. In the preferred embodiment above described this added useful life of the rolls is obtained at a comparatively insignificant added cost.

Having fully disclosed the preferred embodiment of my invention, I claim:

l. A temple roll comprising a roll body having a central portion of resilient fabric-gripping material and a selvage engaging end portion of hard wear-resisting material.

2. A temple roll comprising a roll body having a central portion of resilient fabric-gripping material and fabric-engaging end portions of a hard wear-resisting material.

3. A temple roll comprising a core having fabric-engaging covering thereon, said covering at the central portion of the roll being of a resilient fabric-gripping material and said covering at the selvage end of the roll being of a hard wear-resisting material.

4. A temple roll comprising a tubular core having its end portions covered with fabric-engaging members of hard wear-resisting material, the portion of said core between said members being covered with resilient fabric-gripping material and the external surface of said resilient covering being provided With fabric engaging projections.
