8 Claims. (Cl. 189295) This invention pertains to loom temples, and;

more particularly relates to such temples having a plurality of fabric gripping rollers supported in the temple head. I

Prior temples of the type mentioned have comprised a pod having one or more fabric gripping rollers therein and a cap containing a single fabric gripping roller. The cloth passed between the single roller in the cap and the rollers in the pod. In such prior construction the gripping surfaces for holding the cloth were very small, as they comprised only a small part of the circumferential surfaces of the rollers.

The principal object of the present invention is to provide a loom temple having a plurality. of cloth engaging rollers, an endless belt encasing at least two of the rollers, and another rollerpressed into engagement with the belt whereby a large contact surface is formed between the belt and the third roller.

The foregoing and other objects of the invention are accomplished in the construction illus trated on the accompanying drawing of which:

Fig. 1 is a plan View showing the preferred.

embodiment of the temple with the cloth in position therein;

Fig. 2 is a view partly in section taken on line 22 of Fig. 1;

Fig. 3 is a view in cross-section taken substantially on line 33 of Fig. 1, and

Fig. 4 is a perspective view showing the relation of the rollers.

The temple shown on the drawing is by way of illustration only as my invention is adaptable to any type of temple in which a plurality of rollers are employed and wherein certain of the rollers are located on the opposite side of the cloth from the other rollers.

The particular temple shown includes a housing I of conventional design, adapted to be fixed to the framework of a loom in any suitable manner. A temple bar 2 is slidably mounted in the housing I in the usual manner and is provided with a laterally extending head wherein fabric gripping rollers are mounted. The head includes a base member or pod 3 which in the present instance is formed integrally with the bar 2. The head also includes a cover member or cap 4 which is comprised of an elongated body detachably secured to the pod by screw bolt 5 I and held in position by a tongue and groove 6.

A plurality of rollers may be mounted in the pod. In the present instances two rollers 1 and 8 are shown as being rotatably mounted in the pod 3 as by being mounted on fixed pins 9 and ID, the pins being parallel and spaced apart longitudinally of the cloth. The rollers I and 8 may be made of wood or any other suitable material and are shown as being provided with flanges I l-l2. However, washers may be used instead of the flanges, either a separate washer for each roller or a single elongated washer for both rollers. An endless belt I3 is mounted on and encasesthe rollers l and 8. Belt I3 is made of resilient material such as rubber, imitation rubber, etc., and is held in place on the rollers by the flanges iI--l2. The outer surface of belt l3 may be roughened or ribbed if thought desirable to form a fabric gripping surface.

The cap 4 may have front and rear fabric guiding bars l4 and i5 respectively and end walls I 6 and I1. The end walls are slotted vertically as at l8, Fig. 2, and the slots are open at their lower ends. A roll pin I9 is loosely positioned in the slots for vertically adjustable movement therein. Such movement is controlled by adjusting screws 20-2l. Screws 202l are held in adjusted position by lock nuts 22-23. A roller 24 is rotatably mounted on roller pin I9. The roller may be made of rubber, synthetic rubber or any other type of suitable fabric gripping material. In order to increase the gripping power of the roller 24 it may be grooved as shown to provide projecting ribs 25. Roller 24 may be mounted in the cap 4 with the longitudinal axis of the roller located intermediate the rollers l and 8 and lying in a horizontal plane vertically spaced from that of rollers 1 and 8, but with its lower principal surface extending below the plane tangent to the upper periphery of the rollers 1 and 8. In this position roller 24 presses against the belt l3 and forms therewith a tortuous or sinuous path for the cloth. The surface area of contact between roller 24 and belt [3 is greater than would be the case if belt I3 were omitted and roller 24 merely had tangential contact with rollers 1 and 8. Due to this increased area a more effective gripping is produced. Belt I3 being resilient and roller 24 being vertically adjustable, the contact area is adjustable by moving roller 24 towards or from belt l3. Adjusting screws 20--2l permit this adjustment and lock nuts 2223 hold screws 202l and roller 24 in adjusted position. The tortuous path of the cloth and the large contacting area between roller 24 and belt I3 is clearly shown in Fig. 3.

It should be noted that while the particular temple shown comprises a head having a pod and a detachable cap, my invention is not limited to such temple structure but is adaptable to any type of temple structure upon which rollers are mounted. Further, while I have shown only three rollers, it is obvious that as many rollers as thought desirable may be employed and while I have shown the endless belt mounted on rollers it is also obvious that the belt may be mounted on stationary supports.

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

1. In a loom temple for holding cloth as it is being woven, a base member, an endless belt mounted on said base member, a fabric gripping member mounted on said base member on the opposite side of the cloth from said belt and adjustable means for pressing said fabric gripping member into engagement with said belt whereby said fabric gripping member will be pressed into engagement with and partially enveloped by said belt.

2. A loom temple comprising a base member having an endless belt mounted therein, a fabric gripping member, means secured to said base for supporting said fabric gripping member above said belt and adjustable means for pressing said fabric gripping member downwardly into engagement with said belt whereby the bottom surface of said fabric gripping member will be pressed into and partially enveloped by said belt.

3. A loom temple comprising a base member,

an endless belt mounted on said base member, a

roller, means secured to said base member for supporting said roller above said belt and adjustable means for pressing said roller downwardly into engagement with said belt whereby the bottom surface of said roller will be pressed into and partially enveloped by said belt.

4. A loom temple comprising a base member having a plurality of rollers mounted thereon, an endless belt mounted on said rollers, a fabric gripping roller, means secured to said base member for supporting said roller above said belt and means for adjustably pressing said fabric gripping roller downwardly into engagement with said endless belt whereby the bottom surface of said fabric gripping roller will be pressed into and partially enveloped by said endless belt.

5. A loom temple comprising a pod having a plurality of rollers mounted therein, an endless belt mounted on said rollers, said belt having a fabric gripping surface, a cap secured on said pod, a fabric gripping roller mounted in said cap and means for adjustably pressing said fabric gripping roller downwardly into engagement with said endless belt whereby the bottom surface of said fabric gripping roller will be pressed into and partially enveloped by said endless belt.

6. In a loom temple for holding cloth as it is being woven, a pod having a pair of spaced parallel rollers below the cloth, an endless belt mounted on said rollers, a cap detachably secured on said pod, a fabric gripping roller mounted in said cap above the cloth, said fabric gripping roller being parallel to said pair of rollers and having its axis intermediate the axis of said pair of rollers, said fabric gripping roller being adapted to press the cloth against said endless belt.

7. In a loom temple for holding cloth as it is being woven, a pod having a pair of spaced parallel rollers below the cloth, an endless resilient belt mounted on said rollers, a cap detachably secured on said pod, a fabric gripping roller mounted in said cap above the cloth, said fabric gripping roller being parallel to said pair of rollers and having its axis intermediate the axis of said pair of rollers and means for adjustably pressing said fabric gripping roller downwardly into engagement with said endless belt whereby the bottom surface of said fabric gripping roller will be pressed against and partially enveloped by said endless belt.

8. A loom temple comprising a pod, a pair of spaced parallel rollers mounted in said pod, an endless resilient belt mounted on said rollers, the outer surface of said belt being roughened to provide a friction fabric gripping surface, a cap detachably secured on said pod, said cap having end walls provided with open-ended slots, a roll pin loosely supported in said open-ended slots, a fabric gripping roller mounted on said roll pin between said end walls, said fabric gripping roller being of resilient fabric gripping material and being ribbed circumferentially, adjustable means for pressing said roll pin downwardly whereby said fabric gripping roller is brought into adjustable engagement with said endless belt and means for locking said adjusting means in adjusted position.
