IMPROVEMENT IN TEMPLES FOR LOOMS.

Specification forming part of Letters Patent No.- 71,541, dated November 26, 1867.

To all whom it may concern:

Be it known that I, EDGAR F. SHAW, of the city of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement on Temples for Looms, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawing, forming part of this specification, and in which- Figure 1 represents a plan of a temple constructed according to my improvement; Fig. 2, a side or edge view of the same; Fig. 3, an end view thereof, and Fig. 4 a longitudinal section of one of the temple-rolls detached.

This my improvement relatesto a roll or roller-temples; and consists in the employment of rolls of a conical character, having, or preferably so, elastic frictional peripheries, and composed, say, wholly or in part, of india-rubber, its preparations, or the equivalents of these.

Said invention also consists in a divided and adjustable construction of the temple or its bar, whereby the taper rolls in either temple may be set closer to or farther from each other; and, furthermore, in such connection said invention consists in a peculiar hinged construction of such divided bar, in combination with an adj ustin g-screw, or its equivalent, whereby the rolls may not only be adjusted as regards their frictional 'hold upon the cloth, but be swung or loosely separated the one from the other, to facilitate entry of the cloth between them.

Referring to the accompanying drawings, the bar or beam of the temple, which may be attached in theusual manner, one on either side of the loom, may be described as constructed of a stationary part, A, and movable portion B, the latter being hinged, say, as at a, to the former. These two parts A and B each carry or have attached to them at their forward ends angular projections,- arms, or brackets O C, that serve to form hearings to the spindles on which the temple-rolls D D are hung to rotate. These rolls D D are of a conical character,

'each being-formed, say, of the frustum of a cone, with their smaller diameters toward the inside of the web, and axially arranged so that the peripheries of the two meet, or, rather, holding the selvage in between them, bear of any suitable preparation of india-rubber, or

its equivalent, or be otherwise suitably constructed, but preferably so as to present an elastic frictional bearing-surface on the cloth, web, or selvage running therethroughsay, formed of wood for their bodies b, covered by rubber c, or its equivalent, and fitted with a metallic bush to reduce friction and wear of the rolls on their spindles.

By the construction thus described it will readily be. perceived that the rolls of the temples on opposite sides of the loom will exerta right and left hand or opposite side draft upon the cloth to keep it properly spread and prevent curling, the distance traveled in the rotation of the rolls increasing outward by reason of their increasing diameters in that direction, and operating to draw the cloth outward, while the elastic and frictional character of the peripheries of the rolls gives the requisite bite to prevent slipping in thus keeping the cloth at a stretch without tearing or injuring the selvage, and without interfering with or retarding the passage of the cloth through the temples by the take-up motion of the loom.

Furthermore, it will be seen that the adjusting device, as herein described, of the one roll relatively to another in either temple serves a twofold purposenamely, first, of allowing the roll carried by the movable part of the bar to be widely and loosely separated from the roll connected with the other part thereof sufficiently to admit of placing conveniently, and preparatory to the loom commencingj, its work, the selvage end of the cloth between the rolls; and, secondly, answers the purpose of controlling and regulating the drawing in or spreading of the cloth when being woven by increasing or diminishing the friction produced by pressing or adjusting the two rolls toward each other.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A temple consisting of two tapering rolls arranged relatively to each other and to the Web substantially as herein shown and described.

2. The combination of the taper rolls D D with the bar or beam of the temple, constructed in two parts, for support and adj ustment of the rolls, or one of them, relatively to the other, essentially as specified.

3. The combination of the taper rolls D D, arms or brackets O G, temple-beam, made up of a stationary part, A, andmovable portion B, hinged, as at a, and made capable of adjustment or separation, as a loose jaw, by means of a screw, E, or its equivalent, substantially as and for the purposes herein set forth.

EDGAR F. SHAW.
