Be it known that l. \l'iLLiAM J. Buaunrr.

citizen of the United States, residing atv lirooklyn. in the county of Kings and State of New York. have invented a certain new and useful In'iprovment in 'inding-Machines. of which the following is a. full, clear concise. and exact description.

This invention relates to automatic winding machines. such as are run by power and arrange insulated wire in helical coils on bobbins, automatically stopping when a predetermined number of turns have been wound.

The object of this invention to provide for stopping the Winding when any number of turns have been wound and then if the electrical resistance is not at a fixed point (owing to variation in the wire), automatically winding the required additional number of turns, stopping automatically: and further. to provide automatic means where by the start to wind is at the end of a bobbin instead of at an intermediate point where the stop may have been made to secure the required number of turns and amount of resistance, and combining with this means a hand operated device to throw the last named means in and out of operation, as with a single simple movement.

The accompanying drawings illustrate the invention.

Figure 1 is a top plan View with part of the main shaft broken away; Fig. 2 is a rear elevation partly in section showing the means whereby the start is automatically made at one end or the other of the bobbin; Fig. 3 is a broken section showing the cam for reciprocating the wire guide, and the means for determining the number of layers wound; Fig. 4 showsthe connection between the cam and the gradually advancing tripping device: Figs. 3, 6 and 7 are sectional views of details of construe tion. and Fig. 8 is a perspective view clearly illustrating the relation of the parts in operation.

lhe bobbin or core to be wound with wire is placed between the driven head block a. and the tail block 7) both located on a suit-- able bed plate, and said core or bobbin is Specification of Letters Patent.

clutched in any suitable manner. Wire is supplied from an overhead reel supl'iorted on a rod (not shown) located in s cket c. Tle head a is driven by an electric motor connected on shaft m. which motor is con l'ltlllGtl by a starting switch and resistance fit) in manner well known. Shaft. m is connected to shaft 21 by gearing 1, and shaft 11 is connected by worm gear (not shown) to transverse shaft 22 on which is fixed cam Cam A: engages rollers 23 and .24 en a reciprocating carriage 0 supporting the wire guide 200. which guides the wire so that it lies closely in successhe helical turns, in layers. on the bobbin 203. The cam A. re verses the ll'lOVtllTltllt of this guide. at each end of its trip from one ide to the other; cam 7r turns continuously in one direction and. as shown in Fig. t. has carried the guide to its extreme righthand limit.

A tension device, like that shown and described in United States Letters Patent No. $90.24 dated June 9. tool issued upon the appl' *ation of F. ll. lloveridge, employed: and a device to compensate for the increasing diameter of the bobbin to be wound is employed which ditl'ers in some respects from that shown in said Loveridgo patent. After leaving said tension device the wire passes to the wire guide ".200. a companion roller 20 prevents displacement of the wire from the grooy ed periphery of the guide 200; the guide 300 is rotatably supported at 201. on a lever 2UP; pivoted at '20 on a standard 207. The upper end of standard 207. is bifurcatc-tl and carries a cam wheel 208. on a short shaft 20ft in bearings in the standard 207. so that the shaft is free to rotate: on the end of shaft 209 is a disk with a milled periphery 210 for hand manipulation. .\n arm Ell is pivoted on standard 207 and its free outer end is forced downward by a spring 21:). rd 213 has one end fast on the end of lever 211; it is turned around shaft 201 and its opposite end is fast to said shaft: the arrangement being su h that shaft 20!) and cam 208 have a tcl'idcncy to rotate it) ward the rear side of the machine. but this tendency to rotate is held in check by a brake 214 engaging the periphery of the cam sure of the wire guide 2 .10 on t f the bobbin 205.

To determine the number of, layers to be wound before the desired automatic, stop occurs, there a did-130 loose on shaft or hearing the periphery of disk is toothed and it is held by a stop 31 'adjustably fixed on standard disk 30 carries a resilient stop and disk 30 is graduated and can be rotated and set to indicate the required number of to and fro excursions of the wire guide as will be now described. On shaft 25 ratchet wheel 33 is free to rotate; wheel 33' carries a roller stop 34; a spiral spring in connects wheel 33 to shaft 25; the spring a (Fig. 2) is in a box y and returns wheel 33 to its starting position when it .is released, after being stepped ahead to the tripping oint. When wheel 33 is at its starting point the roller 34 on its surface engages spring stop 35 on the surface of disk 30. The ratchet wheel 33 is advanced st p by step by a pawl 36 pivoted at. 37 on the oscillating lever 38; a sp l\! ovl 3G in engagement with while holding pawl 40, retains wheel 3 during Q0 tin e pawl 36 is on its return movemen l.

The oscillating lever 38 is journaled on the short shaft 25,and its lower end is bifurcated. There is a roller 41 on a two- part disk 42, 43, on shaft 22 held in fixed but adjustable position by a ring or coTlar 45 and a set screw 46; the roller 41 is between the bifurcations of lever 38 and as shaft 22 rotates, roller 41 engages first one leg of lever 38 and then the other, this advances and withdraws pawl 36 which thus advances ratchet wheel 33, one tooth for each rotation of shaft 22. or each complete rotation of cam is, or each complete excursion of the wire guide; so that two layers are wound for the advance of each tooth or space on the periphery of wheel '33. The starting lever is shown at h, pivoted on shaft 2 and in Fig. 8 is shown retracted by spring 47. iVhen moved forward, or to the left Fig. 3, or away from the operator, a projection 101 on lever it passes out from under projection 48 on pawl 36 and a stop 50 onlever it passes from under projection 51 on pawl 40, so that said pawls drop into engagement with wheel 33; when retracted, or moved to the right Fig. 3, lever it, raises pawls 36 and -10; so that in its forward position starting lever ]L releases pawls 36 and 40 and they engage t hlpivoted at t V d forward by spring 61. tarting ievcr /'i lrw a curved '()Illt1(t edge 4?), Fig. 33, which i. notched or slotted, as shown in l J. 2 and and plate or lever has a projecting hardened steel contact-tooth. beveled on its free or contact edge, adjustably secured by a screw. This tooth rides on the curved periphery of lever plate it and enters the notch in lever plate It as said lever is moved forward to start the machine into operation. in inclined edge 63, (Fig. 2), of lever 60, takes a position in the path of roller 351 on ratchet wheel 33; this roller presses lever 60 to the left (Fig. 2) and releases starting lever h which in turn lifts pawls 36 and 40 described so that wheel 33 returns to its starting point, with stop 34 engaging stop 35. A projection 64 on starting lever It strikes motor-switch holding-catch 65 (Fig. 1) opens the circuit and the machine stops.

The machinery so far described provides for setting the stop mechanism to automatically trip at the end of any number of com plete layers, and at an intermediate point in a layer; this is done by setting the disk 30 to automatically stop at the end of a layer and the roller 41 to produce such stop at an intermediate point in a layer. This invention provides an ilnproved means for setting the stop mechanism at an intermediate point in any layerby changing the position of the roller 41 after loosening the screw 16 (Fig. 3) on the ring 45 which clamps the two half disks 42 and 43; a graduated scale 150 being used to determine the position of the parts 42 and 43. This novel invention further provides means to automatically start the winding operation every time at the initial end of the bobbin, or at either end, 'as may be determined upon without regard to Where it may have been stopped intermediately; and to do this without manipulating the driving apparatus or the adjusting devices held by set screws as described; audit is combined with a simple device by which said means for automatically stopping at an end may be thrown in and out, of operation by a single movement.

As before stated lever (30 is pivoted at 62, it catches and holds the starting lever 11 in its forward or running position; lever 60 is tripped when roller 34, on wheel 33, strikes incline 63. Means are provided to trip lever 60 by the movement of the reciprocating two- part carriage 0, 0, which carries the rail If and on which is located carrier or standard 207 supporting an arm 83 extending forthreaded end Ward, and upon which there is a slide 82 (Fig. 6). There is a fixed post 87 (Figs. 1

and 7) supporting pivoted lever 84; one end of lever 84 enters a perforation 85 in lever 60 (Fig. 4). A horizontally disposed rod 10 (Fig. 1) is pivoted to lever 84 at 86; there is a parallel rod '0 jointed at90- to a short section 89 (Fig. 2) pivotally supported at 88 in a post 91 (Fig. 1) supported upon the tail block. The lower terminal of section 89 is bifurcated and straddles the screw of rod 10; on the screw threaded end of rod to are limiting nuts 92 and 93 and there is a check nut for each. The rods '0 and w are mutually supported by a stop 95, fixed on rod w through which there is a perforation in which rod 1) passes; there is a stop 94 fast on rod 1;. By pushing slide 82 up so that it is in position to engage nut 92 when carriage 0 is moving toward the tail block 6, rod 'w is moved and through link 84 it moves lever 60. This automatically stops the machine at the limit of the winding operation. Byplacing slide 82 on the'tail block side of stop 94 its upper edge strikes stop 94 on rod 4) and moves rod 11 to the right and rod w to the left or toward the block b, and lever 60 is tripped as before, but in this case it is tripped when" the wire guide is at the opposite end of the bobbin or the opposite end of'its movement. Slide 82 is now withdrawn. By changing the position of stop nut 92 or the position of stop 94, the winding may be automatically stopped at either end of the bobbin by advancing slide 82 and the automatic device described is quickly thrown inand out by a single movement of the slide 82 which is located at the front center of the machine and is easily and quickly moved.

In operation a blank spool is inserted between the holding devices a and 6, starting lever h is moved forward, and the machine starts. The resistance of the wire'is such that it is necessary to stop the winding op- I eration when twenty and one-half layers of helical convolutions have been wound onthe spool. This has been provided for by loosening screw 46, Fig. 3, and moving the two- part disk 42, 43, with the contact roller 41 to the predetermined point on the scale 150 so that staring lever 72, will be tripped at that point. When the machine is thus automatically stopped the wound spool is withdrawn. It-"is necessary to begin the winding for the next spool at one end to have the winding terminate at the half layer, the same as in the case of the spool first wound. We must therefore start at the end. The winding guide is automatically moved to this initial point each and every time by moy-ing up the slide 82 by hand when the first-spool is removed and a second spool in serted, then throwing lever h forward-this starts the machine and it isautoniatically stopped at the initial end of the blank spool, the end of the wire is then brought into en gagement with the blank spool,the machine is started again and again automatically stopped at a half way point when twenty and one-half layers are wound.

This improved device provides a manually operated means for quickly throwing into action an automatic device for complet ing the excursion of the wire guide over the fractional art of a layer and automatically stopping t 1e wire guide at the same initial point, so that the Winding may always start at the 'same terminal point.
