LOOM- TEMPLE.

SPECIFICATION forming part of Letters Patent No. 405,387, dated June 18, 1889.

7 Application filed May 7, 1888. Serial No. 278,115. (No model.)

To all whom it may concern.-

Be it known that I, NICHOLAS I. ALLEN, of Boston, county of Suffolk, State of Massachusetts, have invented an Impro vement in Loomlemples, of which the following description, in'connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In weaving many classes of goods templerolls having sharp pin-pointed teeth to enter the goods or fabric are objectionable,because they displace the threads and leave small holes or spaces in the fabric, and sometimes, especially if the sharp points of the teeth have been dulled or blunted, the teeth when retiring from the fabric in the rotation of the roll pull from the fabric portions of the same.

Many attempts have been made to do away with the pin-pointed teeth which pass entirely through the fabric, and among the rolls which have been tried have been those covered with sand or emery, and the rolls have also been corrugated and roughened in Various ways; but such attempts have not been eminently successful, and the pin pointed teeth are more generally in use, notwithstanding their objections. In my efforts to improve temple-rolls to bet ter adapt them for use thereby, and especially light-weight fabrics, I have discovered that by covering the body of the roll with fish-skin the roll so produced is quite as efficient in holding the fabric distended as the pin-pointed teeth; but with the fish-skin the points on the skin which engage and hold the fabric to keep it distended do not pass through the fabric.

My invention therefore consists, essentially, in a temple having a roll provided with a surface of fish-skin, as will be described.

Figure 1 is a side elevation of my improved roll detached from the temple; Fig. 2, an end view of the same. Fig. 3 is a View showing a portion of the fish-skin magnified, and Fig. 4 shows a temple with my improved roll therein.

The body a of the roll is preferably composed of wood or similar lightweight material, and is provided with a mandrel or journal w, all in usual manner,

The covering B for the roll consists, preferably, of dogfish-skin-a skinprovided with a series of sharp points I), (well represented in the magnified riew, Fig. 3,) the said scales inclining in substantially the same direction as shown in Fig. 4; and in this my invention it will be understood that the points of the skin are directed directly toward that end of the temple-roll which is to be nearest the sel'- vage .of the cloth to be held by the roll, instead of-being directed in the direction of rotation of the roll. The points are too short and blunt to penetrate the fabric, but are sufficiently sharp and fine to engage the fabric passed over it and prevent the same from being drawn over the roller longitudinally or in the direction of the length of the roller, the rolls at opposite sides of the cloth having the fish-skin applied ,to them in such manner that the points of one roll incline in the opposite direction to the points on the other roll, one roll acting to hold the fabric along one and the other roll along the other selvage. The fish-skin does not serve to engage and feed the fabric, for the journals of the rolls are mounted loosely in the usual temple-head, the rolls being rotated only by the pull of the cloth on them, the rolls merely acting to prevent the slipping or contraction of the web or cloth in the direction of its width, or in the line of the axis of rotation of the roll, as the usual reed and take-up act to move the fabric in the loom.

The skin may be attached to the roll A in any desired manner, and preferably will be applied in a moist condition by means of cement or glue, and as it dries the skin contracts sufficiently and clings closely and smoothly to the body of the roll, the sharp points I) serving in place of the teeth of the ordinary temple, but without tearing or injuring the fabric, for the scales Z) do not pass through the fabric.

I do not confine myself strictly to the use of dogfish-skin for covering the roll, as the skin of the shark, or of other fish having skin of a similar character, may be employed.

The cap 0 and pod 61, forming part of the temple-head in which the roll rotates, are and may be of usual construction.

' Prior to my invention I am aware that attempts have been made to make the rough surface of fish-skin available, and this use has been attempted in connection with the rollers of cotton-gins; and so, also, I am aware that it has been proposed to cover a surface with fish-skin and utilize the same in the devicesfor h oldin g tautan d taking up the tubular fabric produced by a circular-knitting machine in lieu of the usual weights which are commonly hung on a tubular knitted web to keep it taut on the needles. Prior to my invention I am not, however, aware thata roller to be used in a loom-temple has ever been covered with fish-skin. To render such combination useful, care must be taken, by examination of the fish-skin, that the little hard points thereof are arranged to point toward the end of the roll, for it arranged to pointin the direction of rotation of the roll, rather than toward the end of the roll, the skin would not act toprevent the contraction of the cloth widthwise, which is the especial purpose of my invention. Temple-rolls are commonly provided with fine metal teeth, and many rough substances have been applied to temple-rolls with the hope of securin g a surface which would engage with fine cloth having soft-spun threads and not displace them, as do the metallic teeth, and cause open places, thus spoiling the goods; but all rough substances so far used-such as emery, glass, rubber, &c.have no utility and are practically worthless. I have found by experiment that dogfish-skin, when applied to a templeroll in the particular manner described herein, affords a surface over which the cloth will not slip or dragin the direction of thelength of the roll, and consequently the cloth may be kept distended in the direction of its width by a roll located at each selvage, the width of the fabric being thereby kept substantially uniform. The hard sharp points on the skin are so fine and numerous and they engage the cloth at so many points in so small an 'area, that the numerous points, although they but partially penetrate the cloth, are enabled to hold it distended uniformly, and inasmuch as the points do not extend through the cloth, and as they are so very closely set together, the threads of the cloth are not disturbed.

A roll covered with dogfish-skin, and applied substantially in the manner described and employed in a temple, constitutes a temple which may be successfully used in aloom to hold distended widthwise many fabrics upon which it is now impossible to employ a roller-temple.

I claim 1. The combination, with a temple-head, of a roll covered with fishskin applied thereto, substantially as described.

2. The herein-described temple-roll, consisting of a body, as a, and a covering of fishskin, having the points of the skin directed toward the end of the roll, to thereby prevent the cloth slipping on the said covering in the line of the axis of rotation of the roll, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
