To all whom it may concern:

Be it known that I, EUGENE R. Emnmesi a citizen of die United States, residing Phillipsdale, in the oounty o1" Providencs and State of Bloods Island. have invented certain new and useful Improvements in l/Vinding-lvlachines, of which the following is a full, clean and exact description.

- My inventio reintes to a method of 'winding ineiaillc s e by the tension of the Wires itself as it tr v"the successive layers,

The Wire is shown applied in somewhat the form it takes in prectioe with a kinked portion between. the points A and F5. and a straight llllli fillll po tion between lllt point-s E and.

Moreover, the are of movement shown ar H would bring the delivery roller too for forward at its central position; It is, fllQlGfOIQ, clear that the ordinary forms Winding machines employing swinging arms cannot-be used for spools oi any imi snoili lengths. In order to Wind. sp ols of any length i'tlis necessary to have different arrangement, and by the l 8S6nl' iY-eniion holly in X ideal 6on5 quires.

Referring again to Fl it Wiil, sesn tlmi; if

which practice reoonducting the wind through a i aim to secure substanfine wire. Accordingly the arm is fed proptated and the wire W maintained in an almost perpendicular relation under suitable tension, that the wire will be properly coiled -upon the spool. If the wire W by reason of excessive feed acquires the inclination W, the feed will be too coarse, and if on account of an insufiicient feed, it takes the inclination W, the turn, will have a tendency to mount upon the preceding one. The ideal condition is to have a very slight rearward inclination so that the turn will coil closely against the preceding one with out mounting upon it.

Referring now to Fig. l, I will explain the essential principles of my invention, and show that it is effective for the purpose of securing the ideal conditions. 1 indicates a lead screw having a handle 2 by which it is turned. 3 indicates a block internally threaded so as to move upon the lead screw, and having a swinging arm 4. 5 indicates the delivery roller, parts 4 and 5, correspondingto the parts D and F of the diagrammatic representation previously referred to. G indicates the spool which is shown with one layer partially wound, and the various positions which the arm 4 can acquire are indicated in dotted linesalong the length of the spool. In. the use of this apparatus, the swinging arm 4 is positioned approximately perpendicular to the spool, and the winding commenced under suitable conditions of tension and speed. As long as the arm a is perpendicular, or substant-jially so, the plane of the wire corresponds with the-ideal conditions above mentioned,

and shown in Fig. 2 "W. In other words, the wire isbeing directed to the spool in almost perpei'idicularrelation, but lagging very slightly behind on account of the friction ofthc inging arm pivots. The deiivery rolie may be located some distance back of the rent edge of the spool, as indicated in Fig. i, so that a considerable force is created to i'i'iore the arm, even. with very the layer, without lagging nil so that the wire would have a tendency to mount preceding turn. As the arm beet deflected owing to the progress oi? the wind, the conditions become less and lo I avorable, although they are suflicicntly nwm'abie for all practical purposes during a moderate arc of movement of the arm.

By my present invention I arrange means by which the operator. who is necessarily present during the winding operation, can

erly and follt appreciably l3 forcibly move the arm support laterally an amount corresponding to its movement, so that its perpendicular relation is constrained to continue. For this proposal have indicated the lead screw 1 threaded into the block 3, and operated by the handle 2, so that the operator may turn the handle and keep the wire guiding arm approximately perpendicular. If the arm is approximately perpendicular, it is sufiicient for all practical purposes, and it is perfectly within the capabilities of any operator to maintain the arm approximately perpendicular, particularly if said arm is comparatively lon Under these circumstances, the arm wil sometimes be exactly perpendicular to the spool, and sometimes forward and sometimes back of such relation, but the wire will substantially follow the ideal path, as indicated in Fig. 2, under all these conditions, due to the very slight retardation of the arm pivots. As will afterward ap ear, I provide means for minutely adjusting the delivery roller forward and back with relation to the spool, so that any predetermined tension can be made effective to feed the arm along with the progress of the layer. Inasmuch as the arm always remains substantially perpendicular, this distance remains constant for any adjustment. It is evident that the delivery roller would be located at different places fordifferent kinds of wire, and any case at a point sulficient-ly far forward to prevent lateral deviations of the arm from appreciably varying the inclination of the wire, and at the same time suiliciently far back to give sulficient force to make the arm follow the progress of the layer. Thus the proper position of the deli very roller is a sort of balance or compromise, which has to be determined by experiment for each particular job. As the layer approaches the heads of the spool, it is desirable to reverse the same, and the operator may accordingly allow the arm 4 to acquire considerable inclination at the two heads of the spool, as indicated'in dotted lines at K-and L in Fig. 1.. When the arm acquires such an inclination, the wire has a tendency to mount upon the preceding turn, or, in other words, reverse itself, which is exactly what is desired at the two heads of the spool. Accordingly the inclination would be so arrangedtl'iat the reverse would just occur at the time the layer had reached the heads of the spool. A practical form, of consimctz'0n.ln the present application I will describe a simple form of construction for carrying into effect the foregoing principles. The mechanism is presented largely for the purpose of Hitstration, and referen ce is to be had to my companion application, Patent N0.1,057,008, dated Mar. 25, 1913, for'the full specifications of a certain type of commercial ma chine embodying my invention. The present use aims to present the essential parts of the mechanism in suggestive form, by which they can he worked out to suit varying requirements by different persons skilled in the art, who may desire to construct and use the same for their particular purposes.

- The friction of the arrow upon its pivotal supports is sufiicient to give the necessary l announcer rearward inclination or leg to the Wireuhder ordinary circumstances, but I I provide means for increasing the'resistance in case sis tension of the wire or other factors requires it; For this purpose l arrange so a dash pot l9 comprising ii cup 20, secured upon the wire carrying head, and having fans or blades 21 therein. 22 designates a gear wheel secured to the fans or blades and meshing with n segment gear 23, co-

@Tvhe operation of the above mechanism i will-he understood from the preliminary description, and particularly the below descriptionin connection with Fig. 4. It. will be seen that I provide a swinging arm which [is maintained in substantially perpendicular is rela tionto the spool, no matter what the length thereof may be. The arrangement. is

also such that the delivery roller may be 10- Y carted at" any position of forward or back adjustment by manipulating the 'nuts 9, G5 which is a very important adjustment in practice, as it enables theoonditi' ons' no be exactly accorded to theiureeds of any particular wire.- I umelso enabled to adjust the arm 4 vertically by means of the thumb nut; 12. which is desirable in case spools of unusually large or small size are wound.

The arm 4 is so long that it is eflicient for modified arrangement; in. which the. lead screw 1 is dispensed with, and a-rackand In Fig. 6 I have indicated a slightly is a mid-position,

gear segment adjustment substituted therefor. The rack 24 is fixed to the Wire carrying head, and the gear segment 25'm'esl1es therewith and turns with the rod 26 projecting forwardly in the machine. 27 indicates. an arm upon the'rod 526, said arm having a pointer 28, which moves along the surface of the spool. The arrangement is such that the operator may follow the progress of the layer with the pointer, sothat the sup port for the wire carrying arm likewise" follows the course of the layer, and] keeps the arm in perpendicular relation, or approximately so. Wish this arrangement the wi e follows exactly in accordance with its 1 particular needs, and the operator is able to keep the pointer approximately opposite the turn being completed without much difficulty. The delivery roller follows the progress of the layer exactly, and the arm sup-- port mvpioximately in this case, as in the case where the operator manipulates the lead screw to kee) the swin ins arm Jert: J pendicular.
