rEMrLE DEVICE FOR LQOMS.

'To all whom it m ((3 concern:

. Be it known that I, LITFALLAH G. San- BAG, a citizen of the United States, and resident of Boston, inthe county of Suffolk and State of Massachusetts, have invented new and useful. Improvements in Temple Devices for Looms, of which the following is a specification; My invention relates to a temple stand and temple for looms. V

'' 'Qne' object of my invention 1s to provide a simple, cheap and ,durable device adapted to be readily adjusted by unskilled persons,

which shall be more efiicient than present types of temple with respect to the preven tion of shrinkage in width from the tension of the weft, and which shall be free from any tendency to damage the cloth, as by puncturing, tearing, or detaining and pull-' mg on projecting. ends of yarn.

Loom temples of the prior art comprising rotating devices of one sort or another held by a pod, stand or other mounting in such a manner as to engage the cloth between the point reached by the forward stroke of the lay and the breast beam, the

position of'the axis and-the conformation 'of'the roll "forming the temple proper being relied upon to strain the cloth laterally with respect to-its direction of travel to the take-up rolls, are all, so far as I am aware,

defective because of clogging and stoppage due to the stray ends or promoting yarns always found in' greater or less quantity near the'fselva'ge of the new cloth..- It is practically impossible, to, avoid the entrance of an occasionalstray yarn between'the teml roll-proper and :its stud, gudgeon or earing,,whereupon the yarn wraps around the bearing or roll, often stops the rotation ofthe'i temple proper, and often causes dainage to the cloth in the bestpractice of whlch Iain aware.

- pair.

It has heretofore been proposed to shear yarns projecting from the selvage ahead of wholly-successful ins-avoiding grasping an otli jat" this point, sometimes beyond re- In one aspectmy inventionrelates to the provision of means for maintainlng the occasional projecting endfand damaging the cloth under a lateral strainby thefuse'of relatively stationary devices with respect to which the take-up and groivtl ui lovement of the cloth reacts to )la'cethe clothunder a lateral stretching strain. My

vention also relates tothe provision of an improved mounting or stand for the stud or other temple devices, and to a weft sever; ing device operating in conjunction with the temple proper sons to shear from the cloth projecting wefts or other waste yarns extending beyond the selvage.

preferred form of adjustment-is'that'- shown in Fig. 3 in which counter-sinks '6 in the base 3 are connected by a slot 'TSo that th'e screws 5 may be loosened andthe baseivad justed ,to conform to' a? difierent width' o clot-h, without changingthe "direction- *of the bearing 4. Sliding freely in the bore in .the bearing 4 a threaded stem 10 is provided with lock nuts 11 and with keying means to prevent rotation of the stem 10 The temple proper is carried by a mount-.

ing integral with or attached to head 15. which may be provided with a depending lug 16 adapted to be struck by the lay 18 at the forward extremity of its heat.

By the construction described. the motion of the temple carried by the head 15 of the stem 10 in a direction contrary to the motion of the cloth or Like the direction of growth of the cloth is caused by the spring ll. and the extent of this motion (which takes the temple to a new place in the cloth at each beat of the lay) is adjusted by the lock nuts 11. I have found in practice that structures usual in the art for mounting temples and comprising integral restraining means corresponding to the lock nuts 11 are soon rendered useless by wear. the adjustment at 11 for the backward position of the temple mounting being of importance to the correct operation of any form of temple.

In order to avoid the defect of'the. clogging of rotating rolls. as mentioned above.

I have devised means for this purpose charac terized by the absence of parts puncturing and adapted to firmly grasp the edges of the cloth. One preferred form of this means is illustrated in Figs. 5.

By the illustrative construction 'I am enabled to rotate them in their hearings in the casing long use.

The gage and form of inclined grooves. such as the spiral threads of the round roll- s 20 and 21 may bevaried in accordance with but I 'find in practice that quarter-inch rolls-threaded-12 to the inch, for one instance only, are practaking against the flat to present afresh wear surface after and by its relative under an outward the center of the ticable for awide range of cotton cloths, the temple specified having the characteristics above noted. ,QOneatlvantage of my device lies in the freedom from any possibility of entanglementiwith the rolls 20, 21 of loose ends, there being no moving parts capable of wrapping .an end into a bearing. But I neyertheless findit desirable to provide for cutting projecting wefts or other waste at the selvage, and t'or this purposev I am able to ut iZ e the stronghold taken upon the cloth and upon the weft with relation to the warp in the cloth to enable cuttingthe waste ends at, the temple in a superior manner.

.Xot only the cloth but the wefts within the clothbeing held at passage of the rolls and 21 under restraint against lateral DIOVQIDQDt-lfl either direction, I am able to cut the projecting weft by gripping it at a point separated trom the selvage. and then cutting the run of yarn between the selvage and the point at which it is gripped. Pivoted on a shoulder screw fast in the casing '22. a gravity, lever 36 having a heavy canrend 37 in the path of the lay 18 is provided, with a sharpened depending knife blade 38. 'hen the lay beats forward. the lever 36 is rocked downward to give the blade 38 a cutting stroke. for instance carrying it through the plane of the cloth. Surrounding the screw 35, to be actuated by the lever-36.- (as by having an end e'ntering ahole 39 of the lever) I provide a resilient gripping device l0 which may be made as shown of spring-wire carrying in a loop at oneend a yielding block 41 of rubber, felt, leather or the like.

Integral'with or attached ,to the cover 2i I provide an anvil l2, for instance as shown by a downward and outward bend 4-3 of, a thin integral-extension of the material of the cover 2-1:. The casing 22 is provided with a slot it having if desired "a flared'-mo1 1th. adapted to receive a projecting weft or other "end as the cloth moves into the ten1'ple.and preferably I provide the anvil 2 with a downwardly and inwardly bent extension 45 to direct the yarns above anvil 4:2 and so placed astogive free play tothe blade 38 of lever 36, as shown.

, One, or bothtemples may be provided with cutters and clamps as described.

By'the described constructions. relativemotion of the cloth presents the loose ends at the selvage in the slot H and over the anvil, l2. Upon the next beat of the lay after entrance of such a waste end, the block *1 is first brought down upon the waste end, and the lever 36 is then further actuated to cut the tautly held'wast-e yarn. The cloth to which the waste yarn is attached is meanwhile .crinkled or crimped in the grip of the bodies 2Q, 21, so that the operation of the blade 38 is of no eficct to pull a weft or damagethe cloth;

It will be observedthatthe stretching pull on the cloth, by my device. between the areas measured by the length and width of the cloth ain engagement with the bodies This area is larger" than in any prior temple device "ofwhi'ch I am aware, and I am thereby enabled to exert 'a' greater strain on weak cloth than has beenjh'eretofore possible. while preventing injury to the cloth in the mannerdescribed. I

\Vhile I have described and shownrotatable bodies 20, 21. it will'be miderstood by those skilled in the art that the active 'sur-. faces of said bodies 'are those contacting with the cloth. and that in "some. cases the bodies 20 or 21. or both. may be segments of cylinders or other solid forms not round as shown. and that'the respective bodies 20 '21 may in that case be imjulnted throughout their length on or be integral with surfaces of a casing 22 and a cover it. by which the respective bodies are held in the relation to each other and the cloth r/ above explained.

For convenience of illustrgtion. I have shown the severing device mounted on but one of the temple devices. but I 't-ontem ilate providing similar severing n'ieans' fonfboth temples when desirable or necessary. especially in'looms providiiig for holding a. shuttle or shuttles idle at each'side of the cloth. 'hile I have 1nentione'd severin" projecting wet'ts. .it will be understood that my device readily picks up and severs as well any componei'ityarn projecting at the selvage and liable to be caught and pulled at the temple.
