MACHINE FOR WINDING WIRE.

SPECIFICATION forming part of Letters Patent No. 417,219, dated December 17, 1889. Application filed July 19, 1889. Serial No. 318,002- (No model.)

To all whom it may concern:

Be it known that I, EBENEZER BEALS, a citizen of the United States, residing at Norwich, in the county of Chenango and State of New York, have invented certain new and useful Improvements in Machines for lVinding WVire with Covering Material, of which the following is a specification.

My invention relates more especially to ma- IO chines for winding ribbons or strips of cloth or paper in a layer or layers spirally around or upon a central core or wire to protect or insulate it electrically or mechanically. Its object is to produce a cheap, simple, and effective machine for attaining this end, which will be automatically stopped by the breakage of the covering material or the reduction of the tension thereon below a given point, and in which the relation of the strips to the wire may be adjusted by means of suitable adj ustable guide-fin gers over which they pass, whereby the height at which the spiral windings are applied may be varied. These ends I attain by certain novel combinations and organizations of instrmnentalities hereinafter specified.

The accompanying drawings represent so much of a machine embodying all my improvements as is necessary to illustrate the subject-matter herein claimed in the best way now known to me. Some of them, however, may be used without the others and in machines diifering somewhat in their details of construction from those herein shown. Unless otherwise described, the parts shown are of well-known construction.

Figure 1 is a perspective view of amachine embodying my invention from the righthand and front side; Fig. 2, a rear elevation of the same with the frame in section; Fig. 3, a plan of the same with the rotating table and all parts above it removed; Fig. 4, a detail elevation of the strip-guiding devices with the rotating table in section; Fig. 5, a plan view of the same; Fig. 6, a detail rear elevation of the brake mechanism which aids in stopping the machine; Fig. 7, a detail plan view of the same;

and Fig.8, a vertical central section through one of the strip-roll disks, showing its supporting-stud.

The mechanism is shown as mounted partly in a main frame A, having suitable upright posts connected by horizontal bars or

framepieces

1, 2, 3, and 9, and partly in a supplemental frame C, mounted on the main frame. A main driving-shaft 5, journaled in the lower part of the main frame, carries a loose pulley at and a fast pulley 6. A bevel-gear 6' drives a corresponding pinion 7 on a short vertical tubular shaft 8, journaled centrally in the main frame. A revolving table or flier 10, mounted on the upper end of this shaft, is perforated concentrically therewith for the passage of the wire B to be covered. This table may be of wood or metal of any suitable shape or construction, and is shown as a solid disk provided with a depending peripheral flange 11 and radial slots 12, in which latter vertical studs 18 areadjustable by means of downwardly projecting tongues 19, fitting 7o loosely in their respective slots, and the positions of which are controlled by nuts 20.

Guide-finger bars 14:, rocking vertically on pivots in the upper ends of the studs 18, are each provided on their inner ends with a downwardly-projecting stop 16 and with a lateral projection 15, horizontally and longitudinally perforated to receive the guide-finger 17, longitudinally and rotatably adj ustable therein, and a set-screw 153, for clamping the finger in the desired position. These fingers are provided with bent ends or right angular projections 23, under which the strips wound upon the wire pass.

Any desired number of studs G for carrying the rolls of paper or other material are secured upon the upper surface of the revolving flier or carrier 10 by means of downwardly-projecting studs G and clamp-nuts G Disks 21, having suitable hubs, fit loosely 0 on these studs, being held down on shoulders thereon by springs g and tension-nut g, and the paper-strip rolls 21 are placed between the plate g and disk 21. Any desired tension may thus be put upon the rolls of cov- 5 ering material.

Each strip or ribbon at: leads from its respective roll around a guide-post 22 at the end of its corresponding slot, thence radially inward under the end 23 of the guide-finger 17, and thence upwardly around the wire B to be covered, the guide-fingers being adjusted at different distances from the wire to regulate the height at which the strips meet the wire, so that the strips are laid spirally upon the wire, the winding of one strip breaking joints with that of another. The strains of the strips lift the guide-fingers and fingerbars, and thus normally hold up the bars 14 and their stops 16.

As will be seen from Fig. 1, the fingers are not only adjustable endwise to vary their relation to the wire, but they are also reversible in their supports for the same purpose. The fingers nearest the wire apply the first windings, and the outside winding being applied at a greater height than the others is shown as having its guide-finger reversed in its support to obtain the required distance between its end 23 and the wire. The paper or other strips having been properly applied to the wire, the parts suitably adjusted, and the machine started, the. wire will be continuously fed through it, as presently described, and the paper strips will be wound thereon in superposed spirals; but in the event of any one of the strips breaking, the machine is automatically promptly stopped by the mechanism described below. A catch or lock piece 27, having a notch 28 and curved point 29, rocks longitudinally on a pivot i on a cross-bar 26 beneath the flier or carrier 10. There is an upwardly-projecting flange 30 on the front of this lock-piece, or on that side opposite the notch and point, and the catch is jointed or pivoted to a rod 32, projecting through the front of the frame, in which it may loosely play.

A belt-shifting yoke 33 is mounted on a rod 35, movable endwise in suitable bearings in the frame and encircled by a spring secured at one end to the cross-bar 26 and at the other to the rod. The spring therefore normally tends to move the rod to the left, as seen in the drawings, and throw the beltshifter so as to transfer the belt to the idle pulley. A short upwardly-proj ecting arm or stud 34 on the shifting yoke normally engages with the notch 28 of the catch. thenever one of the strips breaks or its tension becomes too much reduced, its guide-finger 17 and bar 14 drop to the position shown in Fig. 2 and in dotted linesin Fig. 4, when the stop 16 projects sufficiently beneath the carrier to abut against the flange on the catch or lock plate and rock it inwardly on its pivot, which action releases the stud 34 from the notch 28, and the spring 36 throws the rod inward, or to the left, carrying the belt-shifting yoke 33, and thus transferring the belt from the fast pulley to the loose pulley and disconnecting the driving power from the machine.

The stoppage is assisted by the following brake mechanism: A vertical shaft 38, suitably journaled in the frame, carries an arm on which the brake-shoe 37 is secured in any well-known way. A laterally-projecting bar 40 on the upper end of this vertical shaft 38, has an inclined slot 41 in its-outer end, in which works a roller 42, journaled in a short arm 43, secured on the spring-actuated shipper-rod by a set-screw, so as to be longitudinally adjustable thereon. The slotway 41 diverges outwardly from the rod 35, and consequently when the latter is thrown endwise to shift the belt the roller 42 forces the rod outwardly, thus rocking the shaft 38 and causing the brake-shoe to bear on the surface of the fast pulley 6 and promptly to arrest its rotation. The machine is thus very quickly stopped by the co-operation of the belt-shifter and brake. These parts can be thrown into action to stop the machine at any time by withdrawing the notch 28 from the stud 34 by pulling the handle 32. The reverse movement of this handle returns these parts to their normal position, and this aids in interlocking the stud and notch when the belt is shifted back tothe fast pulley, and the guide-finger is again lifted by the paper strip.

The rear or inner end 46 of a lever 44, rocking on a pivot 45, works loosely in a notch or seat in the top of the yoke 33, to shift the belt from the loose to the fast pulley, and thus start the machine. \Vhen thus moved to the right, the stop-arm 34 will slip past the curved end or point 29 of the lock-plate int-o the notch 28, against the tension of the spring 36, and thus lock the parts in gear again.

The wire passes from a suitable reel (shown by dotted lines in Fig. 2) over a grooved pulley 56 and up through the tubular shaft 8 and flier 10 past or through horizontal smoothing arms or blocks 25, secured on uprights mounted upon and revolving with the carrier-table and connected at the top by a cross-bar 24, having a central eye concentric with the core of the tubular shaft 8, through which eye'the wire also passes. The strips are thus successively wound upon the wire as it is fed upward, and is smoothed and compacted thereon by the smoothing arms 25. The wrapped or covered wire is wound several times around grooved rollers 47 48 to tighten and further smooth the covering and give the necessary draft or friction. These rollers are mounted in shafts journaled in a supplementary frame 0, forming part of the main frame A. A bevel-gear on the driving-shaft 5 drives a corresponding pinion 54 on a vertical shaft 545, carrying a worm 52, driving a pinion 51 011 the shaft 49 of the lower winding drum or wheel 47. A pulley on this shaft carries a belt 50, driving a reel (not shown) on which the covered wire is finally wound. The wheel 48 is driven from thewheel 47 by the wire itself, thus drawing the wire through the machine as fast as it is covered, and regulating its tension upon the reel 011 which itis finally wound.
