5 Claims.

This invention relates to loom temple rolls, and more particularly to improved roll structures having novel gripping surfaces for engaging the selvage edges of the cloth to move the same outwardly during the beating up action of the lay.

One object of the invention is the provision of temple rolls having fabric covered cloth engaging surfaces, which are provided with or comprise spirally arranged raised portions forming ribs serving to engage and move the selvage edges of the cloth outwardly as the rolls are rotated by the forward movement of the cloth.

Another object of the invention is the provision in devices of this character of a fabric covering for temple rolls formed from or having incorporated therein a tractive or resilient material adapted to engage resiliently or grip the cloth as it presses into engagement therewith without forming roll marks in the selvage edges of the cloth.

A further object of the invention is the provision of devices of this character formed with cores of substantially rigid material which are provided with spirally ribbed surfaces having tubular fabric sections sleeved thereon which form, with the ribbed surfaces of the core, face projecting spiral ribs for engaging the cloth.

Another object of the invention is the provision in devices of this character of cloth engaging fabric surfaces which have been treated to render the fabric resistant to the action of acids, oils or alkalies which may be present in the fibres of the cloth being woven.

Other objects and advantages of the invention relate to various improved details of construction and novel arrangements of the parts as Will `be more fully set forth in the detailed description to follow.

Referring to the drawing:

Fig. 1 is a top plan view of a portion of a loorrl temple, showing the same in operative relation with cloth in the process of its formation on a loom, Fig. 2 is a side elevational view, partially in section, as taken along the line 2-2 of Fig. l, showing one operative position of the loom temple rolls in connection with a holder head of conventional type,

Fig. 3 is a side elevational view, partially in section, of one form of roll structure embodying the invention,

Fig. 4 is a similar view of a somewhat modied form of roll structure, and,

Fig. 5 is a similar view of a further modified form of temple roll.

Heretofore, various forms and types of roll structures have been provided for use in loom temples toengage the selvage edges of the cloth being woven for holding the edges outwardly and preventing abrasion of or injury to the warp threads by the reed as the lay beam moves to beat up the threads. Devices of this character, as previously employed, range from pin studded rolls to rolls having spirally ribbed toothed surfaces formed from a variety of materials. In the usevof rolls of the character described it is found that those having sharp cloth engaging face portions tend to break `the threads and form holes in the selvage edges of the cloth, while it is common for certain of such rolls to indent the cloth leavingmore or less permanent marks in the selvage edges, all of which detracts from the .appearance and value of the cloth.

The present invention is adapted to overcome these defects'by providing a roll structure having a fabric cloth engaging outer surface which will not injure or indent the formed cloth, even when using the finest threads and forming the most fragile material. Y

In the form of the invention illustrated herein, l designates generally a loom temple, which may be secured to the breast beam of a loom in the usual or any suitable manner, and which comprises a head 2 having a pod portion 3 and cap 4 for receiving loom temple rolls 5 which may be rotatably supported by shafts 6 suitably mounted in the end walls of the pod 3 or cap 4 of the loom temple head. The cap 4 may be mounted for adjustment towards or from the pod 3 and secured in the desired adjusted relation relative thereto by screws or bolts 1. As shown in Fig. 1 of the drawing, the cloth being formed is indicated by the'reference 1character 8 and is engaged by the temple rolls slightly in advance of the fell 9.v

The temple roll 5 shown in Fig. 3 of the drawing comprises a core l0 formed with a shaft receiving opening I l extending therethrough, which kcore may be formed from wood or any other suitable natural or synthetic material adapted for the purpose and may have a rigid or slightly resilient outer surface as maybe found desirable lin practice. In the form of thel invention shown in Fig. 3 of the drawing, the core Hl is provided with an enlarged rounded central portion I2, up-

on which` are formed one or more raised spiral `vmaterial is sleeved over the enlarged central portion l2 of the core and has ends Il extending outwardly therefrom and adapted to be engaged and held by metal caps I8 mounted on the reduced ends l1 of the core portion of theroll.

The inner ends I9 of the metal caps I8 may bel spun down over the adjacent ends I1 of the fabric I 8 to hold the fabric cover firmly in position upon the enlarged central portion l2 of the core. The opposite end 20 of each cap I8 is inturned to fit over the free end of itsr reduced end portion i5, as shown at theright in'Fig.l3 of the drawing. The raised spiral rib or ribs i4 formed on the -central porti-on l2 of the core press the tubular fabric section I6 outwardly to V' form a raised spiral rib or ribs 22 therein for engagement with the cloth to holdn the ycentral portion thereof taut as the rolls are frotated by suitable lacquer or proofing ,materiaL such as Bakelite, to render the fabric impervious to the action of -a-cids or alkalis which maybe present in the cloth being formed. I may also incorporate threads or strands of tractive material,

such as rubber, asbestos, BunafS, Koroseal, or

Neoprene in the woven or braided tubular Vsections to give them added traction upon the cloth.

In the form of the inventionshown `in Fig'. 4 of the drawing, the roll 24 comprses'a core" 25 having a shaft receiving opening 26 formed therein and shaped to provide anenlarged central cylindrical portion 21 and reduced ends 28'.v The enlarged central portion 21 may haveV a cylindrical outer surface L29 to receive a tubularfabric section 3U, which may be woven, braided or Aotherwise formed, and which, as shown, has incorporated therein a spirally positioned cord or enlarged strand 32 woven, braided or otherwise embodied within the tubular fabric sec-tion. Metal caps 33 lare fitted over the reduced ends 2B, and

tion 30 to hold the same firmly in position upon l the enlarged central portion 21 of the core.'`

In the form of the invention shownV inl-Fig. 5 of the drawing, the roll 35 has a core member 36 provided with a shaft receiving opening 31, :and is of a shape similar ,to that shown in Figfl of the drawing, having a central enlarged cylindrical portion 38, having a cylindrical outer face 39, and reduced end portions .40. In this form of the inventiona tubular fabric cover 42 may, as invthe preceding forms, be woven,A braided or otherwise formed, and is shown as provided with a plurality of slightly raised thread portions 44 which are 'spaced from each other and so positioned in the tubular fabric ast-to form together one or more substantially continuously extending, spirally arranged, raised, cloth engaging areas in the tubular fabric which projectfoutwardly slightly beyond the remaining surface of the tubular fabric to engage thev selvage edges of the cloth being formed and rmove lthe Same outwardly as the rolls are rotated through'movement of the cloth. In this, as in the forms previously shown, metal caps 46 may be employed having ends forced into engagement with or spun over the free ends =41 of the tubular fabric cover 42 to hold the fabric -cover securely in position upon the enlarged central portion 38 of the core In each form of the invention, the tubular fabric cover may be made from any suitable or desired form of woven, braided or knitted fibrous material, vvsuch as, silk, rayon, cotton, ramie, or thelike, and may have incorporated therein filaments or threads of rubber, asbestos, or other material adapted to exert a tractive force on the surface of the cloth being formed. The tubular vfabric may be and is preferably treated, espe- Y cially when formed from a single fibrous material, such as cotton, wool, rayon or the like, by being partially or ywholly impregnated with a suitable lacquer, or the like, such as Bakelite, to render the fibres more or less impervious to the action of acids, oils or jalkalis, which may be present in the cloth being formed and in order to preserve the fabric material against distortion. Ineach case, the tubular fabric material may be firmly secured to the enlarged central portion oi the core member by being glued or otherwise secured thereto throughout all or a portion of its extent so that'it will maintainv an even surface throughout, or it may be secured thereto only at the outer ends, as by means'of thel metal end caps.

In the forms shown in Figs. 4 and 5, the spirally positioned heavy cord or thread 29 and the enlarged or raised thread portions 44 may be formed from orv contain threads of rubber, Neoprene; Buna-S,l Korose'al, asbestos fibres or the like, or from anyother suitable form of' thread or cord adapted to exert ahigh tractive eectV upon the cloth being formed'.

In each form of the invention shown the rolls may be positioned in the holder to engage either the top or, bottom surface of the cloth being formed,'or they may be arranged to engage opposite side faces of the cloth, as has been the practice heretofore with various forms of temple rolls.

What I claim is: v A Y 1. A loom temple roll comprising Aa Ysubstantially cylindrical core member, and a tubular cover formed from strands cylindrically interlaced together throughout the longitudinal and circumferential extent of the tubular shape sleeved upon the core member and having a raised spiral rib portion formed therein and projecting outwardlyradially of the tubular cover beyond the remaining surface portionsthereof when the tubular cover member is in position upon said core member.
