7 Claims.

Thisinvention relates to temple rollers, that is to say, to the gripping rollers used in loom temples for spreading the cloth adjacent the fell thereof, thereby to eliminate the strain on the dents of the reed which would otherwise occur by reason of the contraction-in the width of the cloth which occursafter the beat up.

The invention relates more particularly to an improved construction of the temple roller to provide agripping surface-of unique character so that said rollers may be used in connection with the finer fabrics such as silk, rayon and the like, in the weaving of which it'is not permissible to use temple rollers having projecting pins or the like for engaging the cloth.

. The principal object of the present invention is to provide" an improved form of temple roller adaptable for gripping and holding the cloth spread without injury to the same.

A further object of the invention is toprovide a temple roller the engaging surface of. which is formed of a strand :of cord, wire or other suitable material so wound on a core that a greater spreading action will be obtained than with temple rollers of this general type whichhave heretofore been used or suggested.

A. further object of the invention is to provide a temple roller which maybe inexpensively constructed and which has certain improved details of construction as will hereinafter appear.

The nature and characteristic features of the present invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which:

Figure l is an elevational view illustrating a temple roller embodying the main features of the present invention;

Fig. 2 is a longitudinal section thereof;

Fig. 3 is a perspective view illustrating a portion of one of the temple rollers of the present invention in an intermediate stage of its manufacture;

Fig. 4 is a similar view illustrating the same at a later stage in the manufacture thereof;

Fig. 5 is a similar view of a portion of a completed roller; and

Fig. 6 is a perspective view of a ferrule employed in the structure.

Referring to the drawing, in the particular em bodiment of the invention therein shown, I0 is a hollow cylindrical core preferably made of wood or other fibrous material. The opening II which extends through the core from end to end permits the roller to be mounted on the spindle bolt member of the temple in the usual manner. Each end of the core is provided with a kerf I2 extending chordally across the wall of the end. portion of the core as illustrated in Figs. 3 and 4 of the drawing. Each end of the core I0 is also reduced indiameter as at I3 and is also provided with an internal counterbore as at I4, each for a purpose to be presentlyexplained.

The gripping surface of the roller is provided bymeans of a cord, wire, or strip of suitable 1Q material I5, wound on the external surface of the core in helical convolutions. vWhile heretofore temple rollers have been made with windings of various materials on the external surface of a core, it'has, however, been'customary to wind 15, the same in close convolutions which did not afford a sufficient spreading action,.by reason of the small pitch of the. resulting convolutions, and also because the closeness of the tops of the successive coils more nearly approached a smooth surface particularly-when slightly worn.

The present invention contemplates the use of, at least two strands of different diameters so that the. gripping surface is provided by the strand I5 of larger diameter, while the strand I6 of smaller diameter serves as an effective spacer, thereby to increase the pitch of the convolutions of the gripping strand, and also to separate the tops of successive coils to a greater extent.

It will be readily understood that the strands I5 and I6 may be made of any of the various materials such as have heretofore been suggested in the art, such, for example, as braided linen cord, wire, either plain or braided, rubber, leather or any other suitable material, and of any preferred cross-section.

In the weaving of rayon and similar materials derived from cellulose, it has been found that when the rollers are wound with cords. made of natural cellulosic materials such as linens, a deleterious action occurs, resulting in the quick destruction of the surface of the roller, but by employing a winding in which the strand I5 of larger diameter is made of a cord composed of twisted strips of cellophane, this difficulty is largely overcome, with a resulting longer life for 7 the temple roller.

, adhesive to cause the strands to be permanently cemented to the surface of the core.

Ferrules II, preferably as shown in Fig. 6 of the drawing, are provided for each end of the the ferrule is complemental to the counterbore M at each end of the core. Y I

The ferrules are so dimensioned as to make a relatively tight fit, and When, the same are forced on the end of the core, they will serve to contract the kerfed portion at each end of the core, and thus cause the ends of the strands to be-more' tightly gripped.

It W111 be noted that the; oonvoliitions of the,

gripping strands extend beyond the shoulder provided by the reduced portion at each end of the core, and the outer cylindrical portion' 'of' the ferrule will, when the ferrule is forced into place on the end of the core, slide beneath the convolutions of the windings at this point; thereby'serving to tighten the same at each end. The outer cylindrical wall [8 of the ferrule is provided with a cut-out 20 to permit thesam'e to pass those portions of the windingswhere the same enter the kerfs I2 at the ends of the core.

It should, of course, be understood-that'the windings, may be either right hand or left hand as maybe required to obtain the proper spreading action. i
