' JESSIE JACKSON ROBERTS, OF DOUGLASVILLEyGEORG-FA, ASSIG-N'OR TO DRAIER COR- PORA'IION, OF 'I'IOPEDALE, MASSACHUSETTS,-A CORPORATION OF MAINE LOOM TEMPLE Application filed September 25, 19301. S erialNo. 454,299.

This invention relates to loom temples and is more particularly directedto means for yieldingly balancing the temple rod and cloth engaging means against the lateral pull of the fabric during weaving. v

During thev weaving operation there is a natural tendency forthevclothto contract in width andto counteract such. tendency loom temples have been heretofore arranged, one at-each side of the cloth, adjacent the weaving point. As well understood in the art, the templerod or shank and the cloth engaging member are mounted upon a temple stand with relation to which said parts have a movement towards and from the front of the loome Such recurring movements, however, produce excessive wear between the temple stand and the templerod or shank, with the result that the temples will not act effectively 'upon the cloth. In some cases, also, where thecloth engaging member of the temple is below the plane of movement of the temple rod or shank, such excessive wear is liable to cause the temple engaging member to be tilted with respect to theplane of the cloth.

A These facts have heretofore been well understood and means have been provided in an attempt to prevent such; excessive wear and improper action of the temples, but with thereforeconsists in providing means to act .yieldingly in a lateral direction and inopposition' tovthe cloth pull to insure that even with the occurrence vof. wear in the temple ,partsthe temple engaging members will exert a lateral stress in ,oppositionto the natural tendency of the cloth to contract widthwiseQ :The" invention and new features thereof will best be made clear from the following description and the accompanying drawings .of one good form thereof, e In the drawings:

Fig. 1 is a plan view showing parts of a loom and temples provided with the present invention;

Fig. 2 is an enlarged perspective view of of the cloth.

frames of the loom is the breastbeam 2 on which the temples may be'mounted in any suitable manner as now well understood in theart. v

The lay 3 may also be of usualconstruction andextending frontwardly over the race 0f the lay are thewarp threads a which at the weaving point, are associated with suitable weft or filling threads to form the cloth 6.

' Each of the temples consists of a temple stand l in which is mounted for sliding movementtowardsand from the frontof the loom the temple rodor shank 5. The temple stand may be of any usual construction but as herein shown is of the usual box-like form, and within the temple stand is a spring 6 normally acting to move the temple rod or shank v .60 tion andextending"laterally between the side 5 rearwardly withrpermissive frontward c 'movementQ Extending laterally from the temple head 7 is the temple top or cap 8 in tain it inlateral position against thepull Extending downwardly from the temple head '7 is the finger lO-adapted to be engaged by the lay or a part carried thereby asthe lay moves frontwardly, to thereby ef-' feet frontward movement of the temple engagin'g member and the temple rod or shank 5.

In the presentillustration of the invention the temple is'indicated. as provided with a thread cutter 11 which may be operatedby an actuating member 12 as the lay moves frontwardly. All of the'parts as thus far described may be and are as of usual construction and it will be understood therefrom that the cloth will exert a lateral pull upon the temples at each side thereof during the weaving'operation as the cloth tends to contract.

It is essential, however, that the clothbe prevented from contracting widthwise," and in accordance with the present'invention a yielding memberis associated with the temple rod or shank 5 to exert a yielding lateral stress upon the temples in opposition to the pull of the cloth.

In accordance with the present embodiment of the invention the yielding member for acting as described is secured to the temple rod'or shank 5 and has its front portion bearing upon the temple stand, with the result that not only is the cloth maintained under yielding stress against its natural tendency to contract, but the engaging parts between the temple stand andtemple rod or shank 5 are prevented from undesirable wear.

The temple rod or shank 5 is provided with a shouldered portion 13, Fig. 2, on which rests the rear end portion of the temple balancing or spring member 14 which may be secured to the temple rod or shank 5 by means of a bolt 15 or other suitable means. The temple balancing member is herein shown as aleaf spring 16 which is secured at its rearportion to the temple rod or shank 5, with its free front portion 17 hearing against the side of the temple stand 4:. Between the two ends of the leaf spring the latter is bent outwardly, as at 18, to thereby impart to the free front end portion of the spring an increased spring action tending to. move the temple rod or shank 5 and the cloth engaging member 9 laterally in opposition to' the pull of the cloth as the cloth engaging memberand temple rod or shank are moved frontwardly during the weavingoperation.

' In some cases it may be desirable to provide the free end of the leaf spring 16 with openings 19 to modify to some extent the resilient action of the spring. I

During the weaving operation, the lay will engage the cutter actuator 12 to operate V the cutter and then will similarly engage the finger 10 extending from the temple head, with the result that the 'templerod or shank 5 and the cloth engaging member 9 will be moved frontwardlyagainst the action of the spring 6. At such times the free end 17 of the leaf spring Will-ride along the sideof the temple stand and exert a lateral stress upon thetemple outwardly orin opposition to the pull of the cloth, thereby maintaining the cloth inthe desired widthwise stretchpnder yielding actioniand at the same time prevent undue wear between the temple stand and the temple rod or shank 5. i o V,

'In those cases wherein the temple cutter is employed, the cutter is usually maintained in its inactive position by meansof 'a spring 20,

herein shown as passing about a spring holder or bolt 21 extending laterally from the temple rod or shank 5 with its limb 22 in engagement with a pin 28 extending from the actuator 12. Where such temple cutter is employed, the present ini'rention provides aconvenient and efiective means for securing the opposite end of the spring 20 in fixed position on the temple rod or shank 5, and as shown it will be noted that the end 24 of the spring 20 extends into a recess between the shoulder 13 formed on the temple rod or shank 5 and the end portion of the spring 16. In accordance with the present invention as herein shown and described it will be noted that the cloth iscontinuously subjected to a yielding lateral stress in 0 position to the natural tendency of; the clht-h to contract widthwise during weaving and that the lat eral stress thus placed upon the cloth engaging member and temple rod or shank 5 prevents" undue wear between the parts of the templestand and the temple rod or shank.

What is claimedis: 1. A loom tem le comprising a temple stand, a templero'd or shankmounted for the temple stand, 'atemple rod" or shank mounted for sliding movement on the temple stand, a cloth engagingmember' carried by the temple rod or shank, a flexible member connected to the temple rod or shank rearwardof the temple stand and having a front- "Ward extension bearing upon the exterior of the tem 1e standto automatically exert a lateralyie ding stress on the temple rod or shank in opposition tothe-lateral pull of th cloth during weaving;

3. In a loom temple, the combination of the temple stand, temple rod or shank mounted for sliding movement on the tem le stand, a clothengagin member'carried I y the temple rod-or'shan ,-Qa leaf spring having one end secured to the temple rod'o'r shank rearward of the temple stand and its free end portioninsliiding engagement with a fixed art exterior of the temple stand to yielding y resist the lateral pull of the cloth durin Weaving'as the temple rod or shank is p l I "towards and from the front of the loom.

4. In a loom temple, the combination of a temple stand, a temple rod or shank mounteditor sliding movement in the temple stand,

a cloth engaging member carried bythe temple rod or shank, a leaf spring havin one end secured to the temple rod' or shank adjacent to the cloth engaging member and its free end extending frontwardly into sliding engagement with the side of the temple stand to exert a yielding lateral stress upon the temple rod or shank in opposition to the lateral pull of the cloth as the temple rod or shank moves towards and from the front of the loom during weaving.

5. In a loom temple, the combination of the temple stand, a temple rod or shank mounted for sliding movement in the temple stand and having a cloth engaging member,

a shoulder formed on the temple rod or shank.

frontward of the cloth engaging member, a leaf spring having its rear end portion bearing upon said shoulder, means for securing the leaf spring to the tem le rod orshank with its free front portion bearing yieldingly upon the temple stand to exert a yielding stress upon the temple rod or shank and cloth engaging member in opposition to the lateral pull of the cloth during weaving,

6. In a loom temple, the combination of the temple stand, a temple rod or shank having a cloth engaging member, a leaf spring having its rear end portion secured to the temple rod or shank rearward of the temple stand and formed with a bend frontward of its rear end with the free end of the spring frontward of a fixed surface exterior of the bend resting against the temple stand and exerting a lateral yielding stress upon the temple rod or shank and the cloth engaging member in opposition to the inward pull of the cloth during weaving.

In testimony whereof, I have signed my name to this specification.
