1 Claim. i (Cl. Z55- 54) This invention relates to metal warp guides such as are employed in the combs of warpers, slashers, ballers, and related textile machines, and has particular relation to guides capable of being used in lease combs to raise or lower certain of the ends of warps above or below the plane of normal extent of the sheet of warps so as to form a lease therein.
The object of the present invention is to provide a new and simplified warp guide of cheaper and easier construction and occupying a minimum of space transversely of the warps, which will be capable of diverting the warps which pass through them either above or below the plane of the sheet of warps, while at the same time being selfthreading in the established meaning of this term as signifying that any intermediate portion in the length of the yarn can be introduced sidewise of the yarn into the eye of the guide in threading up. Numerous types of self-threading guides for lease combs have been proposed which were capable only of lifting the warps passing through them above the plane of the sheet, while the types of guides capable of both lifting and depressing their warps with respect to such plane have either not been self-threading, or if possessing this feature have been characterized by a degree of complexity enhancing their cost of manufacture, increasing their width and thus the space they occupied transversely of the warps, and relying for the retention of their warps on the use of points or hooks which tended to catch or break the adjacent Warps, which drawbacks have impaired their utility and their general adoption.
With these and other objects in view, the present invention comprises the novel construction set forth in the accompanying specification and drawings.
In the drawing,
Fig. 1 is a side elevation, Fig. 2 is a front elevation, and Fig. 3 is a top view, of the improved warp guide.
The novel guide comprises a narrow strip of sheet metal of a thickness suited to the Weight and number of warps to be handled by the lease comb, of uniform width throughout its length, of which the lower portion is left in its original state to form the shank I, though provided with the hole 3 to receive the usual retaining wire of the lease comb, while the upper portion is forked, preferably but not necessarily by the removal of a longitudinal tongue of the metal so as to leave two dents 5, l, spaced apart a substantial distance in the plane of the shank. The lower end of the split formed by the removal of the tongue is rounded as indicated at the shoulder 9 to avoid any wedging and cutting of the warp passing through the guide when the warp is in contact with this portion.
The dents 5, l, are respectively bent outwardly at the shoulder S! in opposite directions away from the plane of the shank I, and thence extend parallel to such plane and to each other in spaced mutually offset relation, being again bent inwardly to cross such plane and thus to cross each other in such plane at the point ll intermediate their length, being bent again beyond such crossing point to extend in parallel and spaced relation to each other and to the said plane throughout the remainder of their extent. The divergence and subsequent crossing of the dents creates an eye I3 for the retention of the warp thread I5. Preferably, but not necessarily, each dent is offset from the plane of the shank by the same distance both above and below the crossing point Il, this equal but opposite offsetting .bringing the upper portion of each dent into the same lateral plane as the lower portion of the other dent adjacent the eye I3, as shown in Fig. 2; however, the outward edges of the dents remain in the same planes, taken at right angles to the plane of the shank I, as do the edges of such shank, so that the guide is no wider at its top than at its shank end, as shown in Fig. 1.
With the warp guide mounted in the lease comb with the 'plane of its shank parallel to the course of the wai'ps in the position shown in Fig. 2, the improved eye is threaded with a warp yarn coming from behind the guide by bending any intermediate portion of the warp yarn around the lefthand side and thence across the front of the lefthand dent 5, and thence behind and forward around the right-hand side of the dent 1, in the course indicated by dotted lines at I'I, in Fig. 3, thereafter sliding the warp yarn down into the position I5, in which the yarn extends in a straight line through the eye I3 of the guide.
To facilitate this bending of the warp yarn into zigzag form across the front of rear dent 5 and behind the front dent 1, the latter dentl is preferably made slightly shorter than the rear dent, to make it easier for the operator to throw the rst bend around the rear dent without interference by the forward dent 1, the sliding movement of the warp yarn down toward the eye being begun as soon as this bend is formed around dent 5, so that dent 'I intercepts the warp yarn and forms the companion bend as the operator continues the downward and forward pull which brings the yarn into eye I3. So long as the warp yarn coming from behind the guide is kept tight, the `crossing of the two dents at il at substan tially a right angle to each other prevents upward escape of the thread from the eye, thus enabling all warps which pass through the eyes I3 of the bank of warp guides in the lease comb to be depressed below the plane of the sheet of warps in forming the lease, as Well as enabling these Warps in eyes i3 to be raised above such plane by engagement with shoulders 9 in case it is desired to raise them to form an opposite lease. In this Way the improved warp guide works in both directions, upward and downward.
It is to be noted that the entire guide presents only smooth surfaces and easy bends tothe yarns, with no hooks, points, springs, or other projections intermediate its length to catch the yarns or to fail in use. This non-fouling feature prevents the unwanted deflection of the alternate Warps of the sheet, which pass between each two successive guides but not through the eyes, and thus are desired to maintain their normal position in the plane of the sheet of Wraps during the leaseforming. l
Not only does the simple and compact form of the improved guide permit the use of a Very large number thereof in lease combs of standard length, but also they can be formed out of lightweight and inexpensive metal stock of the simplest form at high speed with a minimum of operations, with obvious economy ofY manufacture.
While I have illustrated and described a certain form in which the invention may be embodied, I am aware that many modifications may be made therein by any person skilled in the art,
4 Without departing from the scope of the invention as expressed in the claim. Therefore, I do not wish to be limited to the particular form shown, or to the details of construction thereof, but what I do claim is:
A Warp guide for lease combs having in combination a flat shank and dents formed integrally therewith by splitting one end of the guide, the dents at points adjacent their junction with the shank being disposed in mutually diverging relation away from the plane of the shank, thereafter converging and crossing to define an eye to guide a warp yarn, and after crossing being continued substantially beyond the eye in parallel to each other on opposite sides of the plane of the shanlr, the dents being spaced apart from each other in thedi'rection of the plane of the shank also to admit an intermediate portion of the length of the yarn into the eye in threading the guide.
