Claims.

This invention relates to improved loom temple rolls characterized by the provision of devices of this character which are adapted to engage and exert a drawing action upon the cloth without liability of creasing or injuring the same, and wherein the rolls themselves are not subject to excessive wear or injury as by the formation of glazed surfaces thereon through contact with the cloth.

One object of the invention is the provision in devices of this character of temple rolls having an exterior cloth engaging surface which is of a resilient character and which is provided with raised spiral ribs having resilient cloth engaging tongues formed thereon capable of providing means in engagement with the cloth for causing movement of the same in the direction of travel of the spiral ribs but of such a nature as not to break the threads or otherwise cause injury to fine fabric materials.

Another object of the invention is the provision in devices of this character of rolls having resilient cloth engaging surfaces provided with spiral ribs and in which the resilient material contains a tractive or frictional element adapted to prevent slippage of the cloth with respect to the roll surface, while at the same time being of such a nature as not to injure the fabric with which it comes in contact.

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 loom temple structure showing the position of the parts in operative relation with a portion of a fabric being formed,

Fig. 2 is a side elevational view of a portion of the temple, showing the location of the roll members in section, as taken substantially along the line 22 of Fig. 1,

Fig. 3 is a perspective view partially in section of one form of roll member embodying the invention,

Fig. 4 is a perspective view of a modified form of roll, and,

Fig. 5 is a perspective view of a further modified form of roll member.

Heretofore, loom temple rolls have been employed for tensioning the cloth and provided with raised spiral ribs extending longitudinally thereof with or without the formation of longitudinal grooves dividing the spiral ribs into projecting teeth. Such rolls have been used both in interfitting relation with other similar rolls for engaging the selvage edges of the cloth as it is passed between the roll faces, as well as in mounting the rolls to engage the cloth as the cloth is passed between the individual rolls and a surface of the roll holder or cover.

Such rolls have been made with the cloth engaging faces formed from resilient material but have not been entirely satisfactory as previously made for the reason that in the employment of the rolls so as to pass the edge of the cloth between mating spiral ribs formed upon adjacent rolls, the cloth assed therebetween is liable to be creased or torn between the interfitting ribs of adjacent rolls. In cases where the cloth is passed between one or more rolls and a firm'surface, the teeth formed by grooving the ribbed surface tends to mar the cloth by imprinting the teeth thereon or even breaking threads in the cloth when fine fabrics are being formed. If the roll surfaces are made with the ribs or teeth sufliciently short or rounded to avoid forming impressions in or injury to the cloth, there is a tendency for the rolls to wear smooth and thus fail to grip the selvage edges with sufficient firmness to stretch the cloth.

The rolls shown herein are adapted to overcome these disadvantages by being provided with outer resilient faces having spiral ribs of a more or less resilient character formed thereon, which ribs are provided with slightly projecting resilient tongues or projections, which tongues may be of somewhat irregular shape and are preferably located irregularly in a direction circumferentially of the roll, so as not to lie in parallel paths longitudinally of the roll. The tongues formed on the spiral ribs are preferably of less extent than the ribs themselves to provide relatively slender, flexible projections of a character capable of gripping the cloth without injury thereto, so as to avoid any danger of injury to the finest fabrics.

The provision of these soft, flexible projecting tongues in irregularlocations on the ribs insures a much more continuous and better gripping engagement of the roll surface with the cloth than has been possible heretofore, and without injury to the fabric. In order to still further increase the gripping action of the roll on the cloth surface and without injury to the cloth, I may add a tractive material, such as asbestos, preferably in a fibrous form, to the resilient material from which the roll surfaces are made, in such a manner that the asbestos fibres may project somewhat from the roll surface, as in the form of a fuzz, which through its inherent tractiveness wil engage the cloth and cause the same to follow the spiral ribs without injury to the fabric.

In the embodiment of the invention illustrated herein, I designates a loom temple which may be secured to the breast beam of a 100m in any suitable or desired manner. The 100m temple may comprise a shank portion 3 carrying a roll supporting holder-head 4 in position to engage the selvage edge of the fabric 5 in the process of its formation.

The holder head 4 may comprise a base portion: 1

6 formed integral with or carried by the shanl13. and provided with bearings for supporting ro tatably temple rolls 8 in substantial parallelism with each other. A cover 9 .may be secured'to the base 6, as by bolts I0, in such amanner asto be capable of being secured in anyone of several adjusted positions towards or' from the surfaces of therollsfl. The-cover 9-has the-face thereof adjacent to the-rolls 8 formed with parallel rounded recesses H connected" by a rounded rib I2 adapted to-lie between the rolls 8 in the assembled position ofthe parts and serve as a guide meansfor-guiding the cloth hritsengaging relation with the rolls: The curved facesof the recesses l I serveto provide supporting-means for the roll engaged'fabric material to assist inits outward travel-undertheinfluence of the spirally ribbed roll surface, as the fabricweb travels through the loominthe process of its: formation; The roll: 8,- as shown in'jFig'. '3; may comprise an inner tubular shell [4 ofv any suitable or-d'esired material and has a tubular cloth engaging outer covering 1510f a resilient character carried by the tubular shell I41 and which may be secured firmly thereto. Each. roll may be mounted: for rotationon'a shaft lb carriediby'the base Giand passedthrough the openingin the inner, tubular shellv l'4 asis common in devices of this character, or otherwiseg'supportedjrotatablyjin clo'tliengaging. position as may be deemed expedient in practice.

The cloth engaging. resilient outer portion- I5 of the rolls may be formed of rubber, cork, Bunafl Neoprene, KoroseaL or any other suitableor. desired natural or synthetic, rubber or thermoplasticv resilient. materialv suitable for the purpose. Inthe form of, the invention shown in Fig. 3 of the. drawing, the. roll. disprovided with oneor more-raisedspiral. ribs I8 formed. on the outer cylindrical surface therebfp A. plurality of thin flexible'tongues or. projections are formed upon andproject outwardly fromthe ribs l8, being preferably so positioned' as to be off-set regularly or irregularly from a. line 2| formed in they surface of, the roll. and locatedin substantial-parallelism with theroll axis Such arrangement of the tongues. provides for their continuous and uniform engagement. with the fabric at all times. 'The tongues zil being of a relatively. thin, flexible character engage the cloth lightly. anddnsure its movement in the directioniof travel of thespiral ribs l8..without' injury to-the finest and most. delicate fabric.

Inthe formof roll structure shownv in. Fig. 4 of the drawing, theroll 8 has the same'gene'ral arrangement of parts. as previously described, and the resilient. outer clothlengaging portion. I5. is similarly provided with a spiral .ribor. ribs 222 In this case, however, the resilient. tongues or projectionsv 23 formedon the spiral ribs 22. are located mainlyIadjacent-toone side edge ofeach rib throughout its extent 'so that they may be employed to press more or less directly against the cloth to urge movement of the same in the direction of travel of the spiral ribs, especially when positioned upon the side edges of the spiral ribs facing the direction of travel of the ribs as the roll rotates in the holder.

In the form of the invention shown in Fig. 5 of the drawing, the roll 8, like those previously shown, comprises a resilient outer cloth engaging portion [5 which is provided with a spiral rib or ribs 24. The spiral ribs 24 differ. from those previously shown in that they are undercut slightly upon one side edge thereof, as indicated at 25, to provide a flexible edge 26. The edge 26 is provided-with thin, flexible tongues or projections 21', which project outwardly and laterally from the ribs and may be irregularly positioned circumferentially' of the roll, as previously described; The flexible edges of the undercut rib and the thin, resilient tongue 21 carried thereby engage the cloth surface to urge movement of the samein the direction-of travel of the spiral ribs 24.

In eachform of the invention shown, or in other conventional roll forms, when made from a natural or synthetic-rubber or other material which permits of-its incorporation therein, I'may employ a tractiveor frictional element, such as asbestos, preferably in a fibrous form, and'incorporate the same into-the material from which the outer cloth engaginglayer of the roll is formed so that particles of thetractive element may project fromthe-surfaceof the-material or from the-rib surfaces; as'indicatedby-30-on the plain spiral roll surfaced portion 31 as shown in Fig. 3, toengage thecontacting-fa'ce-of the fabric and cause the sametofollow the direction of travel of the spiral ribs;

In each form ofthe inventionshown theflexible tongues or projections formed upon the raised spiral rib or ribs may-be positioned in'any desired location or arrangement with' respect to the rib formation whichisbestadapted to secure a continuously effective resilient engagement of the flexible tongues or'irregulargprojections formed on the rib surfacewiththefabric to insuretravel of the fabric material in the-direction of movement ofthe-spiral ribwithout in.- jury to the fabric material; Tlieparticular form, shape; size and arrangement of the flexible tongues and their location with" respect to the ribs, that is; uponthe raised face or sideedges thereof, may be variedwidely;,dependent'.upon the character of the materialiwithwhich the rolls are to be employed, the particularshapes of; the tongues shown and their arrangementupon and with respect tothespiral .rib or ribs herein being for the purpose" of illustration and'not to; be regarded in a limiting sense other thanas1set forth in the appended claimsL The transverse contounof the rib" orribs' may be varied as'may be deemed expedientrit being regarded as necessary only that'tlfe-tonguesbe formed and arranged on t'he'ribsto *makea' more or less continuous and resilient engagementxwith the fabric for providing a tractive effect thereon to cause the fabric to follow thedirection of travel of the spirally ribbed surface of'theroll as they rotate under the influence, of the moving fabric without causing -injury to the'fabric. A similar result maybe obtained or enhanced by incorporating asbestos within; theresilient material forming, the outer contact face portions of the roll members; V

In the use of" the roll members above doscribed, two or more rolls may be mounted in opposed or contacting relation with each other to draw the fabric therebetween, or the rolls may be mounted in a holder, as shown, and the fabric passed either between the roll surfaces and the holder base or between the roll surfaces and the cover, as may be desired, for exerting a tractive action on the fabric material to move the same outwardly laterally in the process of its formation by the loom.

In its broader aspects, it is the purpose of the invention to provide means for exerting a tractive action on the surface of the fabric being formed in excess of or in addition to that capable of being exerted by the spiral ribs themselves and of a nature least likely to injure or mar the fabric, either by meansof tongues or projections formed on the spiral ribs or by the incorporation of a definitely tractive friction material, such as asbestos, within the resilient material forming the outer contact surface of the roll, or by the use of both of these means together, as may be found desirable in practice.

One or more spiral ribs may be formed upon the outer contact surface of the rolls as may be found desirable in practice, and reference to a single spiral rib formed upon the roll surface is to be taken as including a single or multiple spiral ribbed surface.

What I claim is:

1. A loom temple roll comprising a core, a substantially cylindrical cloth engaging cover formed from homogeneous resilient material sleeved on said core and having a continuous raised rib of substantially uniform basic contour throughout formed in the outer face of and integral with said resilient cover and extending spirally of the roll, and slender frictional elements formed integral with the rib and projecting outwardly from the basic contour of the rib for lightly tractive engagement with the cloth being formed in advance of its engagement by the body portion of the rib.

2. A cloth tensioning roll for loom temples having a substantially cylindrical outer portion formed from a homogeneous resilient material and provided with an integral raised spiral rib formed in the outer face thereof and having a substantially uniform basic cross sectional contour throughout its extent, and a plurality of flexible tongues formed integral with the material of the rib and projecting outwardly from the basic contour thereof for lightly tractive engagement with the cloth being formed, the correspondingly positioned flexible tongues carried by adjacent convolutions of the rib being spaced from each other circumferentially of the roll to provide irregularly positioned contact points for engagement with the cloth.

3. A cloth tensioning roll member for loom temples having a substantially cylindrical outer portion formed from a homogeneous, plastic resilient material and provided upon the outer face thereof with a continuous raised spiral rib integral with said outer portion and of substantially uniform basic contour throughout having a substantially convex face area, and a plurality of tenuous friction tongues integral with said rib and projecting outwardly from portions of the convex areas thereof for exerting a lightly gripping action upon the cloth being formed to cause movement of the cloth in a direction longitudinally of the roll as the roll is rotated by frictional engagement with the cloth.

4. A loom temple roll comprising a core, a cover for said core formed from homogeneous resilient material of a rubber-like character having a raised spiral rib of continuous basic cross section formed in the outer face thereof and undercut upon one side, and a plurality of slender resilient tongues formed integral with said rib and cover and spaced from each other longitudinally of the rib to project outwardly from the outer peripheral portion of the rib adjacent to the undercut edge thereof to engage lightly the surface of a fabric being formed and move the same in a direction longitudinally of the roll as the roll is rotated by engagement with the fabric.

5. A loom temple roll having a substantially cylindrical outer portion formed from a homogeneous, resilient plastic material and provided with a raised spiral rib upon the outer face thereof, which rib is formed integral therewith and is of a continuous basic contour throughout its extent, and a plurality of thin, flexible, resilient tongues integral with said rib and projecting outwardly therefrom adjacent to one lateral edge of the basic portion thereof to engage lightly and resiliently the surface of a fabric being formed.
