COIL-FORMING- APPARATUS.

This invention relates to coil forming apparatus and more particularly to apparatus for winding and forming coils for armatures and stators of dynainos and electrie motors The primary object of the invention is to provide a coil forming apparatus capable of forming the coils directly into the shape desired to fit onto the prepared cores of the armatures or stators.

A further object is to provide a coil forming apparatus readily adjustable to vary the length, width and thickness of the coil and to change the shape of the coil as desired, wherein the parts may be firmly secured in adjusted position to accurately maintain the desired shape and size.

Another object is to provide a coil forming apparatus of few and easily constructed parts that will be suiiicient in operation and inexpensive to manufacture. so

With the above and other objects in view which will readily appear as the invention is better understood, my invention consists in the novel construction, combination and arrangement of parts-to be hereinafter more fully described and particularly pointed out in the appended blaims.

Reference is to be had to the accompany ing drawings illustrating a preferred embodiment of my invention and wherein similar reference numerals designate parts throughout the several views.

In the drawings j Figure 1 is a perspective view of my cell forming apparatus showing the position the wires assume during the formation of the coil;

Fig. 2 is a detail view of one of the longitudinal guide frames;

Fig. 3 is a detail side elevation of one of the lateral guide frames or wings;

wound, with the guide frames in the position shown in Fig. 1.

In the drawings the nume 'al 5 designates a central member or bed which is preferably formed I-section in cross-section to give it rigidity and strength and at the same time provide upper and lower flanges on which may be adjiistably secured the lateral guide frames or wings 6. The lateral guide frames are preferably formed substantially as shown, with an inner portion adapted to slide upon the flanges of the central member or bed 5, to which it may be secured in any adjusted position by thumb screws or other clamps 6?. The wings 6 are shown with spaced outwardlyextending walls 7 between which are mounted the U-shaped guides 8 through which the lateral portions of the wire coils are adapted to pass (see Figs. 1 and 3). In one or both of the walls 7 is threaded an adjusting bolt 9 whereby the U-shaped guide 8 may be firmly clamped in any desired position between the two walls 7. As the entire wing 6 is adjustable on the bed 5 and the U-shaped guide 8 is also adjustable between the walls 7 of the wings, it will be readily apparent that any desired lateral adjustment may be secured on my improved coil forming apparatus.

Firmlysecured in the central bed 5 sub stantially centrally thereof are spaced par allel bars 10 extending from the central bed 5 at substantiallv ri ht angles. On these o b is parallel bars 10 are adjustably mounted the longitudinally guide frames 11, the positions of which may be adjusted at will to var) the distance between the inner portions of the coil in its longitudinal direction. These guide frames are preferably formed substantially as shown in Figs. 1 and 2, and have apertured side pieces 11 adapted to slide over the parallel bars 10 and an intermediate flat spacing member 12 on which are slidably mounted a pair of auxiliary guides 18 which may be adjustably secured at will at any position between the slide members 11 With this construction it is apparent that the distances between the ends of the coil may be varied by sliding the guide frames 11 along the parallel bars and securing them in adjusted position by the thumb screws or clamps 1-1. while the position for the turn or bend 'in the wire coils is regulated by the adjustment of the auxil heift hand U-sh'a-ped guide member.

iary guides 13 which may be moved, as desired, between the apertured side members 11 These auxiliary guide frames 13 are also secured in adjusted position by thumb screws 15 or other forms of clamps, as desired.

From the above it will be seen that my coil forming apparatusprimarily consists of a fixed central portion constructed somewhat in the shape of a cross,-on each of the four arms of which is mounted an adjustable member, the positions of which may be adjusted at will to vary the dimensions of the *coils-in any direction.

In Fig. 1 I have secured the adjustable members in positions to form a wire-coil of substantially the shape shown in Fig. 5, whi'c'h'shape-is particularly adaptable for use with the ordinary cores used in armatures andstatorsbf dynamos and electric motors now on the market. To secure this shape the terminal of the wire is placed substantially as shown'at a, and thence passes over the upper-surface of the spacing bar 12 of 'the right-hand side longitudinal guide frame 'l l-an'd is then bent to pass below the same spacing bar 12 and between the walls of the right-hand U-shaped guide 8, cont1numg below the spacing-bar 12 of the left-hand lon- "gitudinalguide frame 11, and then bent upwardly andover the same spacing bar 12, whence it passes between the walls of the This circuit is repeated as often as desired to form the-coil. By adjusting thepositions of the lateral wings 6 or the longitudinal guide frame 11, varied shapes and configurations of coils can -be formed.

Toenable the distances betweenthe wings 6 to bereadily determined and the wings positioned at any desired distance from the center, Ihave provided a graduated scale 16 omthe flanges of the central bed 5. Similar 'markings-may be placed on the parallel bars .10 todetermine'the spacing of the longitudinal guide frames 11 if desired.

While it will be apparent that the illustrated embodiment of my invention herein disclosed is "well calculated to adequately fulfil the'objects primarily stated, it is to be understood that the invention is susceptible to variation, modification and change without departing from the spirit and scope of ithe inventionas set forth in'the subjoined claims.
