a umen.

To all 107mm it may concern Be it known that I, ARTHUR H. ADAMS, a citizen of the United States, formerly of Spar'kill, in the county of Rockland and State of New York, and now residing n Brussels, Belgium, have invented a certain new and useful Improvementin Semi-Automatic Winding-Machines, of which the following is a full, clear, concise, and exact description.

This invention relates to winding machines and particularly to machines adapted for winding insulated wire in uniform layers on spools.

The general object of my invention is to provide a new and improved winding machine by which the spools may be quickly and satisfactorily wound, and which can be adjusted for the winding of spools of dif ferent lengths with different sizes of wire.

My invention will be understood from the following description taken in connection with the accompanying drawings in which- Figure l is a perspective view of a machine having my invention embodied therein, the table which covers certain of the parts being removed; Fig. 2 is a plan view of the machine; Fig. 3 is a sectional elevation on the line 3-3, Fig. 2; Fig. i is a front elevation, certain parts being broken away; Fig. 5 is a detail plan view showing the scale for indicating the size of wire for which the machine is set; Fig. 6 is a detail plan view of the circuit changing device; and Fig. 7 is a diagram of the circuit through which the magnetic clutch device is controlled.

Referring to the drawings, the major part of the mechanism of the device is mounted on a frame 10 having hollow, spacing pieces 11, and fixed to the under side of a table 12, by bolts like 6, so that the moving parts are below table 12 leaving the upper side of the table free and clear.- There is a track or runway 13, head block b and tail block 0; on track 13 there runs.a front carriage 14, like a tool rest, carrying the grooved guide 7 for guiding the insulated wire in helical convolutions onto the spool s which is to be filled with wire. Spool s has flanges f, one at each end; these are usually circular in outline as shown. There is a back carriage 15 traveling on a track 16; the two carriages l4 and 15 are mechanically united by a lever Specification of Letters Patent.

1T oscillating on a pivot at 18; one end of lever 17 is pivoted ,to back carriage 15 at 19,

the opposite end of lever 17 is pivoted to the front carriage 14 at 20. The front carriage 14: travels in the reverse direction with respect to the movement of the back carriage 15. The motor m which drives or operates the machine as shown, is an electric motor and it is connected directly to the arbor 21 by means of an insulating coupling 22. The arbor 21 supports the spool s, to be wound with wire. There is a hand wheel 24 on shaft or arbor 21 operated as a hand brake stopping the machine when the requisite number of turns have been put upon the spool being wound.

The main shaft or arbor 21 has fixed upon it a worm 25 gearing with a worm wheel 26, fixed on a shaft 27; upon the opposite end of shaft 27 is a gear wheel 28. This wheel 28 meshes with wheel 29 upon a short shaft 30 bearing a worm 31 meshing with a gear wheel on a short vertical shaft 33 on which is fixed pulley p. Passing around pulley 7) is a driving belt 9 made of some fabric. like woven linen, having two

parallel sections

34 and 35, moving in respec tively opposite directions. This belt 9 passes around idle pulley 9 located on a movable support 36 adjustable to and fro with respect to pulley p by a screw operated by a thumb piece 37, by which meansbelt 9 may be tightened. The loose pulleys 38 and 39 are used to adjust the belt and maintain sections 34 and in substantially parallel relation. Two double coil electromagnets $0 and 41 moving with the rear carriage 15 have a common armature 42, pivoted at 43; above armature 42 is a yieldin spring-pressed retaining device 44 to ho ld the armature in either of its two'extreme positions. 'The retaining device 44 is carried in a frame 43 forming part of carriage 15. The belt passes on opposite sides of armature 42, the two sections moving in opposite directions, as already explained, and when the armature 42 is attracted to one side or the other, the 'belt section 34 or is gripped between a magnet pole and the armature, and the carriage 15 is carried along in one direction according as the

belt section

34 or 35 is gripped. The electrical connections are shown in Fig. 7; it will be noticed that circuit is normally closed S a hard rubber shoe 46 and as shown in Figs. 1 and 2, shoe 46 is located in line of movement osition to engage flanges f.

Assumin i, the carriage is started 1 a the is the spool, the travel is from ti l nd flange f laying. the

of the wir upon the spool as it con-v toward the opposite end of the coil. 14. ume the belt locked against the back magnet core, when the front carriage 14 reaches the right-hand end of the spool shoe 46 will strike right-hand spool flange'f and contact 49will beopened, breaking circuit through coils of 41, the armature 42 is drawn over to the front magnet coil 40- clutching carriage '14 to section 35 of the .belt, thus reversing the movement of carriage l4 and the operation is repeated, spool shoe 46 next striking the left-hand spool flange )3, and so on, in succession until the operator stops the machine.

The circuit-closing switch shown in Fig. 6 has two 'stifi' springs 47 and 48, and two

light spring contacts

49 and 50; there are two fixed contacts 51 and 52; each has a hard rubber contact" point 80 projecting through a perforation in the

contact

49 or 50, and engaging contact '47 or 48 so that when contact 45 is moved in one direction, contact 45 separates from contact 49,'and when moved in the other direction, contact 45'separates from contact 50. The shoe 46 is shaped for use with round heads or flanges f. In case square heads or flanges are employed onthe spools tobe' wound, useis made of the round thumb nuts 53 and 54 on the fixed screw rod 55. The space between the inside facesof nuts 53 and 54 is made equal to the winding space upon the coil. The contactsprings shown in Fig. 6 are carriedoupon an adjustable L-shaped bracket 56,

"pivoted at. 57 to an upright 58 of the frame.

A, locking screw 59 projecting through a slot 60 ,inthe bracket 56 into the upright 58 serves'to hold the bracket 56 and the contact springs carried thereby, in any desired position. By loosening the locking screw 59, the shoe/l6 may be positioned to engage the heads of any siz'e'of spool for which the machine is supposed to operate, or'in case square or irregular shape headed spools are to be wound, lowered to engage the nuts 53 and 54. The shoe 46 engaging the nuts 53 and 54 causes the reversals in the movement of,"the ,winding mechanism in exactly the same manner as when the shoe 46 engages the sp'ool heads.

The guide rollerg is suspended from a guide lever 81 by a connecting arm 82. The arm 82 is pivoted to the lever 81 on a .kn urledheaded tension adjusting screw83.

In the various drawings-the guide 9 is shown in the position assumed when a spool is being'wound, but it may be raised and 21 front of the spool n 18 completed he spool from and the other in the non-operative position.

The pawl 86 is normally held in engaging position by a spring 88 located between the guide lever 81 and the latching lever 85. By pressingthe outer ends of levers 81 and 85 together, against the tension of spring 88, the .pawl. 86 may be withdrawn from the notch in disk 87 and the guide 9 moved about the pivot 84 to the other position.

In adjusting the speed of front carriage 14, and to determine the proper pitch at which various kinds and sizes of wire are'to be wound, the operator measures with a micrometer the outside diameter of the wire, and then directs attentionto dial or indicator a graduated to thousandths of an inch. The arm 17, uniting the two carriages 14 and 15 is on a pivot 18; the arm 17 is slotted and pivot 18 extends through the slot. Pivot 18 is supported on a mit62,--slidable in a slot 63 in the fixed bed 64. Nut 62 travels on screw 65, said screw terminating in the knurled circular thumb piece 66. On the same screw 65 is a worm 67 meshing .with a worm wheel 68 on which is fixed a plate havingthereon graduated scales 69 and 7-3. The zero. point for scale 69 is shown at 75, and the zero point for scale 73 at 7 6. The

gears 28 and 29 are of different sizes and are I interchangeable on the

shafts

27 and 30. When said gears are arranged as shown, one of the scales 69 or 73 is used; and when said gears are interchanged the other of said scales is employed. When the

gears

28 and 29 are arranged on the

shafts

27 and 30 as shown, for example, if the machine is to be set towind wire having a diameter .0035 of an inch, the thumb piece 66 is turned until the figures .0035 on the scale 69 are opposite the zero point 75. And if the diameter of the wirehad been .009, the

gears

28 and 29 would have been interchanged on the

shafts

27 and 30, and the front piece 66 ,would have been turned until the figure .009 on the scale 73 was opposite the zero point 76; it being understood that the nut 62 is always in the same position when the gears 28 and29 are changed. With the'arrangement just described, it is obvious that indicates the number of turns put on any spool.
