BEAMING-MACHINE.

Specification of Letters Patent.

Patented Feb. 13, 1912.

Application filed October 21, 1910. Serial No. 588,258.

To all whom it may concern Be it known that I, JOHN WVARBURroma citizen of the United States, residing 1n Paterson, Passaic county, and State of New Jersey, have invented certain new and useful Improvements in Beaming-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skllled in the art to which it appertalns to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to mechanism em ployed in the beaming of a warp and for similar purposes wherein power to cause the winding of the material from one rotary carrier or holder therefor onto another is applied to the receiving carrier or holder, the rotary advance of the supply carrier or holder being caused solely by transmission of the power by pull through the material to the supply carrier or holder.

In beaming machines in general, and hor1- zontal warping and beaming machines in particular, the supply carrier or holder is a comparatively ponderous reel, and it is well known that the inertia thereof required to be overcome following the stopping of the winding for any purpose each time the beam (receiving carrier or holder) is started up opposes such resistance that frequently the strain is more than the material can bear.

It is my object to eliminate, so far as possible, injury to the material from this cause. And this I have accomplished by providing in a machine of the kind indicated comprising an extraneously driven rotary receiving member around which the material to be wound is wound and a rota driven member driven by the pull of the material and from around which the material to be wound is unwound, means for rendering yielding in character the strain imposed on the material consisting of a carrier directly supporting the windings and arranged in coaxial and torsionally yielding, and preferably elastically cushioned, engagement with one of said members.

A further advantage of considerable value follows in the use of my invention when the above-mentioned elastic means is included as a part thereof: In beaming it is generally found desirable to keep the warp under a condition of tension, more or less according to the quality of the goods into which the warp is to be incorporated in the weaving operation, and it is highly important that such tension, whatever it is, should be preserved uniform-a condition heretofore difficult of accomplishment because, particularly when the beaming is stopped for any purpose (as is frequently necessary), there is bound to occur some lost motion as between the beam and reel; by my invention a higher degree of uniformity of tension throughout the entire operation ofbeaming results, due to the tendency of the elastic means referred to to compensate for any lost motion, so that the beamed warp is of much more regular and otherwise better quality than heretofore.

In the accompanying drawings, in which, Figure 1 is a side elevation of suflicient of a warping and beaming machine of the socalled Swiss type to illustrate my invention; Fig. 2 a fragmentary end elevation, partly in section and on a larger scale, showing one embodiment of the invention; Fig. 3 is a vertical sectional view taken on the line .rw in Fig. 2; Figs. 4 and 5 are an inside elevation and a transverse sectional view of a detail of the invention; and, Figs. 6 and 7 are an inside elevation and a transverse sectional view of another detail of the invention, I have illustrated my invention in accordance with the preferred form thereof in which it is that part of the mechanism which is driven by extraneous means to which the improvement is applied.

In said drawings and referring first to Fig. 1, in particular, a is the frame; I) the mechanism whereby the winding up of the material on the receiving carrier or holder is eflected (the details of whose construction will be described later) c the reel (supply carrier or holder) having a circular flange d engaged by the brake-band e and having its shaft f journaled in the bearings g, and it 7c designate two brackets serving in part to support the moving parts of said mechanism. In the sleeve-bearing Z of the bracket 70 is journaled the hub m of a spider n, movement of said spider in the length of its axis being prevented by a screw 0 arranged in the sleeve-bearing and entering an annular groove 29 in hub m. On the hub g of the spider is journaled the gear 1" whose toothed peripheral portion houses or incloses the spider a, the gear being retained on the spider by a disk 1" secured to the left hand face (Fig. 2) of the hub of the spider by the screws 7" shown in Fig. 3. Penetrating the hub of the spider and journaled in the bracket 7a is the shaft 8 of a forked mandrel t, the same having a longitudinal spline or keyway 8' receiving a key or feather s in the hub m of the spider, so that the mandrel, while rotative with the spider, is movable longitudinally of its axis in accordance with the usual purpose in a horizontal warping and beaming machine of the character shownto wit, a so-called Swiss warping and beaming machine. it designates the beam, the same having a trunnion 10 entering the axial bore u of mandrel t (it being understood that the beam is journaled at its opposite end in any suitable bracketnot shownas usual) and adapted to be driven rotatively by the mandrel through the medium of an endless strap 41 or the like connecting one of the arms of the forked part of the mandrel with the stud w on the beam. The spider a has a concentric series of projections a: equidistantly spaced from each other, and projecting from these projections all in the same direction and each in the arc of a circle are the stems y; similarly, the gear 1' has a concentric series of projections m equidistantly spaced from each other, and projecting from these projections all in the same direction (but oppositely to the stems y) and in the arc of a circle are the stems y. The projections w and 00 of the spider and gear extend from the adjoining faces of these parts and lie in substantially the same vertical plane, so that each stem 1 is directly opposed by a stem 1/. Held in place between each two projections w and m by their stems is a spiral spring a, the ends of which receive the stems. 2 designates the usual pawls employed to prevent backward rotation of the mechanism Z), the same engaging the teeth of the gear.

The driving means it comprises a shaft 3 which is journaled in a bracket 4: and carries the pulley or pulleys 2', and on this shaft is fixed a pinion 5 which meshes with the gear 1" and thus serves to drive the mechanism Z).

In View of the foregoing, it will be obvious that upon starting up the driving mechanism the shock imposed upon the warp or other material being wound and due to the rotary advance of the beam under a condition of inertia on the part of the reel will be absorbed, thereby preventing injury to the threads by breakage of some of them or otherwise.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is The combination of the frame, the extraneously driven rotary receiving member around the axis of which the material to be wound is wound, the rotary driven member driven by the pull of the material and from around which the material to be wound is unwound, and means for rendering yielding in character the strain imposed on the material consisting of a torsionally yielding carrier directly supporting the windings and arranged in coaxial relation to one of said members, and a spring interposed between the latter member and the carrier and assuming the torsional yielding pressure of the carrier, substantially as described.

In testimony, that I claim the foregoing I have hereunto set my hand this 20th day of October, 1910.
