Lnasn COMB.

Application filed October 20,1922. Serial No. 595,791.

To all whom it. may concern:

Be it known that I,- CHARLES F. Duran, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Lease Combs, of which the following isa specification.

This invention relates to combs of the character used in warpers, ballers, and similar machines to separate the threads as they are being beamed or otherwise wound to gether. The invention is especially concerned with combs of the type known as lease combs, which have some provision for raising or lowering alternate threads for the purpose of tying or marking them. Lease combs of the character heretofore gen erally used have consisted of a series of e0 guides or flat strips of metal, each provided with a thread guiding eye, and such combs are open to the objection that they are very diflicult to thread. A great many strands of thread, or ends must be handled in most machines of this type and this factadds materially to the difficulty of threading the ends through the eyes of the guides or dents.

It is the chief object of the present in- 80 vention to devise a lease comb which will be self threading and which, at the same time, will be simple and compact in construction, and economical to manufacture. The invention also aims to devise a construction of this character which will not require the use of a greater number of warp guides than do the ordinarycombs. An especially important feature of the invention resides in a novel construction of warp guide for combs of the type mentioned.

The nature of the invention will be readi 1y understood from the following descrip tion, when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the ap ended claims.

eferring now to the drawings:

Fig. l is a rear elevation, partly broken out, of a comb embodying the present invention;

Fig. 2 is a side elevation of a warp guide constructed in accordance with this invention;

Fig. 3 is a cross sectional view on the line 3-3 Fig. 2; and

Fig. 4 is a cross sectional view on the line 4-4, Fig. 1.

Referring first to Figs. 2 and'3, it will be seen that each warp guide comprises two dents. designated at 2 and 3, respectively. with a shank 5. It is contemplated that this device will be punched out of sheet metal by means of suitable punches and dies. The shank 5 preferabl is a straight, fiat piece of metal and the dent Qforms a continuation of the shank and lies in the same plane with it; The dent 3 is offset with reference to the dent 2, as clearly shown in the drawings, so that a space is provided between them through which the strand of thread or garp can be guided, as clearly shown in rojecting from an intermediate point in the dent 3 is a finger 6 which is offset so that it extends across the space between the planes of the two dents and has its end portion positioned substantially in; the plane of the dent 2. This construction provides a space or. slot 7 between the finger 6 and the dent 3, through which space a warp thread is guided. In order to insert a thread in this position it is merely necessary to pass it downwardly between the upper ends of the dents 2 and 3- and pull it forward, this motion causing it to s ip down next to the finger 6. By operating the lease mechanism up, and then down, the thread is caused to slide under the end of the finger and into the slot 7 behind the finger. The finger extends down to a point adjacent to the offset 4 so that it prevents the thread from escaping from the slot after it has once been positioned therein. Subsequently, the move ments of the lease operating mechanism carry this thread up or down. thus producing a lease with the adjacent thread.

It will be observed that the dents 2 and 3 lie in intersecting planes. This arrangement is clearly shown in Figs. 3 and 4 and it gives the desired effective width to the guides. The angle between them will be increased for coarser work so as to increase the space between adjacent threads while still guidin the threads accurately.

Fig. 1 shows a series of these warp guides positioned side by side in a case 8 of a form widely used, the lower ends of the shanks of the guides being threaded on a wire 9. Each shank has a hole 10 therein to receive the wire 9. This case is also provided with ing operation to be performed in the usual manner with only the same number of warp guides that the better forms oi prior combs use for an equal number of ends. It has the advantage over these prior constructions,

however, of being self threading. It will also be appreciated that the warp guides can be manufactured very economically, and since they occupy substantially the same space as prior forms of guides and can be supported and adjusted in thesame manner, they form, when assembled, a very compact and simple comb construction. The fact that the warp guide can be punched out ofsheet metal by very simple dies is an import-ant practical advantage.

It willbe understood-that the invention is not restricted to the precise construction and arrangement shown, but this construction may be modified in various particulars without departing from the spirit or scope of this invention.

Having thus described my invention, what I desire to claim as new is:

1. A. sheet metal warp guide for lease combs, comprising ashank, two dents integral with said shanln saiddents being laterally offset from each other to provide a space between them, one of said dents being located ahead of the other, and a finger inte' 'ral with one of said dents but laterally ofi set therefrom, said finger extending substantially across said space and being positioned closely adjacent to the opposite dent.

' A, sheet metal warp guide for lease combs, comprising a shank, two dents integral with said shank said dents being laterally offset from each=other,-and a finger integral with one of said-dents but offsetv therefrom, so that a substantial portion of said finger lies in the plane of the opposite dent.

3. A sheet metal warp guide for lease combs comp-rising a. shank havingitwoelongated dents extending upwardly therefrom and integral with said shank, said dents being laterally offset from each other,. a finger integral with one of said dents but ofl'- set therefrom into the plane of the other dent, said finger projecting downwardly toward said shank, and an upwardly inclined shoulder connecting the outer edge ofs-aid finger with the edge of the dent fromwhich it projects.

4.. A sheet metal guide for warp combs comprising afiat shank bifurcated at its upper endto form two fiat separated dents laterally offset from each other and extending upward closely adjacent to each other, ,one of said dents forming an extension o'lthe shank and lying in thesame plane therewith, and the other of said dents lying in a plane that intersects the plane of the first dent.

5. A sheet metal warp guide for lease combs, comprising a flat shank having two fiat elongated dents integral with said shank and extending upwardly therefrom closely adjacent to each other,.said dents being laterally offset from eachother, arfinger integral with one of said dents but offset there from into the plane of the opposite dent, said finger extending downwardly from an intermediate point in the dent from which it projects, one of said dents lying in a plane thatv intersects the plane of the opposite dent, and anupwardly inclined shoulder connecting the outer edge of said finger with the edge of the'dent from which it projects.
