WARP GUIDE FOR COMES.

To all whom it may concern:

Be it known that I, ALONZO E. RHOADES, acitizen of the United States, and a resident 'of Hopedale, county of Worcester, State of Masszichusetts, have, invented an Improvementin \Varp Guides for Combs, of which'the following description, in connection with the accompanyingdrawing, is

a specification, like characters on the drawing representing like parts.

This invention relates to metal warp guides such as are employed in the combs of warpers and slashers.

The object of the invention is to provide a simple form of such warp guide so constructed that when a series of warp guides are in position all of the dents will be exactly in line throughout and thus prevent the warp threads from becoming crossed and insure that each warp thread shall be guided in precisely the same manner and in substantial parallelism.

The object of the invention is further to provide a sheet metal warp guide which may be economically and readily manufactured by a welding process.

The object of the invention is further to provide such a warp guide in which a tongue is provided bridging the space between the dents above the shanks and thus guarding against any danger of the warp thread being caught or pinched between the shanks.

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

In the drawings:

Fig. l is a transversecsection of a portion of a comb showing one of the warp guides embodying a preferred form of the invention in place.

Fig. 2 is a front elevation of the warp guide shown in Fig. 1.

Fig. 3 is a view in central vertical cross section of the warp guide shown in Figs. 1 and 2.

The comb herein illustrated in connection with a disclosure of the present invention is of a similar construction to that shown in my prior Patent 818,560 granted April 24, 1906 and as the general construction of such combs is well known and familiar to those skilled in the art no detailed description thereof is necessary. In that construction each warp guide presents a long bottom shank held between the expansible spring holding device 1 and a pair of dents which are arranged parallel to and separated from: each other both laterally and fore and aft: so that one dent is located well forward of the other in the direction of travel of the warp.

' In the construction of the present invention each warp guide comprises a single bottom shank and a pair of warp dents but these warp dents are arranged not only parallel to each other but directly opposite to each other so that when the warp guides are assembled in the series in the comb all of the dents are exactly in line and thus the action of each dent in guiding the warp is precisely the same and all danger of crossing of the warp threads in the comb or further along in their travel is prevented and thus the accurate guidance of the entire sheet of warp threads is secured.

In the preferred construction illustrated the Warp guide is made entirely of flat sheet metal. It comprises a fiat shank 2. The dent 3 forms a prolongation of this shank and preferably extends in the same plane as the shank. The dent 4c is of the same shape as the dent 3' and is provided at its lower end with a short flat shank 5. The dent at is offset from its shank 5' at 6. The shank 5 of the dent 4 is directly superimposed upon the upper portion of the shank 2 so as to lie closely in contact therewith. The two shanks are secured together by a welding process. *For this purpose a spot weld is preferably employed at about the point 7. Thus the two dents are rigidly and permanently united in a very expeditions and economical manner and without leaving any roughnesses or protuberances on the warp guide.

The one dent being separated from the other there is formed between the two dents at their bases where the shanks come together a V-shaped recess 8 and in order to prevent a warp thread from being caught in this V-shaped recess or pinched between the two shanks where they come together a tongue 9 is provided which bridges the space between the dents above the shanks. Preferably this tongue as. illustrated is struck out of the metal of one of the dents as 3 and has its free end seated in an aperture in the other dent. This tongue thus acts to guard the juncture of the shanks and prevents a warp thread from being caught or pinched therebetween;

There is thus produced a very simple, practical and economicalform of dent which obviates thedisadvantages heretofore existing and insures the accurate guiding of the warp threadsby the comb.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

"1, As a new article of manufacture a sheet metal warp guide comprising a flat shank, a flat dent forming a prolongation ofthe shank, a second similar fiat dent haviiig a short flatshank superimposed directly upon and welded to the guide shank with the body of the second dent offset from its shank and extending opposite to, spaced from and parallel with the first dent.

2. Asa new article oi manu facture a sheet metal warp guide comprising the construction defined in claim 1 together with a tongue bridging the space between the dents above the shanks whereby the said tongue acts to prevent thread from being wedged betweenthe shanks.

3. As a new article of manufacture a sheet metal warp guide having the construction defined in claim 1 together with a tongue struck out from the metal of one dent, bridging the space between the dents ab0ve-the shanks and having its free end. seated :in an aperture in the other dent whereby the said tongue-acts to prevent'thread from being wedgec'l between the shanks. V

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