Application led October 3l, 1923. Serial No. 671,962.

This invention relates to machines .for -Winding strands of material, such as wire, thread, ribbon, laments or the like into coils, helices. or bobbins. and particularly to t machines of this `type which are utilized for winding copper wire into electric coils or helices for use in various kinds of electrical apparatus. The particular invention herein described and claimed is in the nature of an l improvement upon machines of the type illustrated in U. S. Patent 1,368,536 issued February 15, 1921. In the patented machine mentioned, a plurality of coils are wound simultaneously in separate zones upon. a l spindle or mandrel, the convoluutions of Wlre being wound in layers superposed one upon the other. During the formation of the layers. the wire is guided to the spindle to lie spirally. thereon by giving the wire a 2U slight movement endwise of the spindle.l It is frequently desirable to lay the wire upon `the splndle with a coarser pitch of the splral turns particularly ending of the coils. In prior machines this has been either impossible or very dilcult to accom lish. v

Au object of this invention is to provide an improved machine of the character described, with which the pitch of the spiraling of the strands ,or wire may, in a simple manner, be varied, more particularly increased, to any desired extent at any periods in the formation of the fcoils, and which will be relatively simple in construction and operation. Other objects and advantages will be apparent from the following description of an embodiment' of the invention, and the novel features will be particularly pointed out hereinafter in claims.

ln the illustrated Vembodiment ot the in-1 vention, the coils are to be wound-in spaced zones upon the winding lspindle 1. The spindle is driven by the aligned'shai't 2 in a manner permittingr removalV of the spindle when the completed coils are to be'removed at the beginning or thetherefrom. The shaft 2 extends through and is rotatably mounted in the housing 3, carried bythe frame 4 of the machine, and is driven from any suitable source of power such as by a belt 5 or equivalent means. The wires' or strands to be wound are conducted rom suitable supply spools (not shown in the drawings), over and around the guiding pulleys 610i the guiding devices 7 that. are

carried by a traverse rod 8. Thehtraverse rod 8 is disposed parallel with the winding spindle and mounted for reciprocation ih an endwise direction so that the wires or strands will bc fed-lengthwise of the spindle'while being wound thereon. This causes the. wires 'to be `wound upon the winding spindle in spiral form, the layers being superposed upon one another by the reversal of movement of the traverse rod.

The worm wheel 10 has a reduced extension 12 the forward. wall of the housing1 3 and carries, upon the exterior end thereof, a ratchet wheel 13, the ratchet wheel being se- 'cured to the worm wheel extension by a semi-cylindrical key 14 in order to cause rotation of the ratchet wheel with the worm wheel. A hand wheel 15 is secured, in any suitable manner such asbv a-pin 16. upon the forward end ofthe shaft 9, the hand wheel having a band flange 17 which embraces the ratchet wheel 13.

A pawl 18 is disposed in akslot'l!) of ther flange 17. so as to move radially of the flange, and upon its inner edge carries a tooth 20 which is adapted to engage between the teeth 21 of the ratchet wheel. A spring 22. at one end, is anchored to the flange 17,

and also thereto at an intermediate point a support 23. The spring extends peripherally around the flange 17 for some distance. and is attached to or `18 so as to yieldingly press the latter laterally toward the teeth 21, and maintain the pawl in engagement with the ratchet wheel.
