To all'whom it may concern;

Be: it known "that I, FRANK citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveiinvented certain new and useful Improvementsin Machines for Forming Electric Conducting-Coils, of which the following is a specification.

My invention relates to improvementsin machines for "forming electric conducting coils for use on armatures and stators for dynamo electric machines.

(Dne of the objects of my invention is to provide-a machine, for so shaping the coils after being wound that they maybe immediately and directly placed upon the armature,=or stator, of a dynamo electric ma chine,"without the necessity of hand manipulation.

respect 1) the other Wires so that the coils -may be instantly placed in their proper places upon the armature or 'withm the stator. Another object of my invention is to provide a coil-forming or extending apparatus comprising a relatively stationary coil-holding portion and a coil extending portion pivoted or hinged together at such point or points as to simulate the axis of the armature and to provide adjusting devices on the two elements of the forming machine whereby the radial distance from the pivotal point may be readily changed or varied according to a scale thereon which indicates directly the length and diameter of the core of the armature. The adjustment of the coil-holding devices is radially movable, according to a scale indicating the diameter of the armature core, and said devices are readily movable or adjustable longitudinally, according to a scale indicating the length of the armature core.

Other and more specific objects of my invention will become readily apparent to persons skilled in the art from a consideration ofathe description when taken in conjunction with the drawings, wherein- B. Snoun, a

In all the views the same reference characters indicate similar parts.

In the use and operation of in device it -is essential that the coils shou dfirst be wound to proper dimension and then, preferably,taped, leaving the lead wires exposed ture or in the stator of a dynamo-electric machine, without further manipulation. :After the coils have been wound and taped,

formed, or shaped, so that they will readily fit upon the active inductive surface of the armature core or 'within the inductive core of the stator of a dynamo-electric machine. I will therefore proceed to describe the machine which forms the coils substantially as they are shown in Figs. 8, l1 and 14 after they have been wound substantially as shown in Figs. 7, 10 and 18. I

70 is a base upon which is mounted a vertical support 71 comprising a longitudinally extending plate 72 with tapering webs-73 and 74. The support 71 is firmly held on the base 70 by means of screws 75. Projecting inwardly from the plate 72 are two vertically extending tapering ribs 76 which atford guiding bearing for a relatively stationary coil holding head 77. This head is vertically movable and adjustable on the said rib supports by means ofa screw 7 8 j which is rotatably secured in rojections 7 9 and 80 that extend inwardly rom the plate 72. The screw 78 takes through a threaded pzrforation in the head 77 and. is located tween the ribs 76, near the center of the plate 72, so that when-the screw 78 is rotated the head 77 may be raised or lowered,

,screw '78 by means of a pin 81 and-ahandle, 82- isj a convenient means for rotating the as desired. The collar 80 issecured to the screw. -The head 77 is dovetailed as at 86, 'for sliding engagement with the relatively stationary but laterally movable wire su ports 87. The wire supports 8787, may

. illustrated in Fig. 3, is a shaft 92, supported in brackets 93 and 94 carried on the base plate 70. The base plate 70 is slotted, as shown at 95, so that the brackets 93 and 94 may be moved to selected positions in a longitudinal direction along the base and secured in such positions by means of screws 95 and 96 respectively. On this shaft is supported a coil expanding frame consisting of the lovers 100 and 101 terminating in bosses 102 and 103 respectively. These bosses are threaded and contain set screws 104 which enter the spline or feather way, 97 in the shaft 92, so that the shaft 92 may be rotated positively with the said movable frame. When the brackets 93 and 94 are moved to selected position, along the base 70, the levers 100 and 101 may also be moved to the-same extent and secured in selected positions by means of the set screws 104.

The levers 100. and 101 each carry a coil holding'bracket 105, 106 and each of the brackets is provided with a coil receiving .slot 107. A bolt, 109 passes through each of the brackets 105 and 106 which are spaced apart by the spacing tube 107 Any one of a number of spacing tubes 107 may be employed so that the distance apart that the levers 100 and 101 may be maintained may thereby be varied, in accordance with the length of the tube 107', and the levers will be positively held in place b means of the bolt 109. For a refinement o adjust- 'ber,' assuming such substantial axis of stator.

ment washers 109 may be used. The coil holding means; employed on the movable coil expanding levers 100 and 101, are vertically adjustable, bodily in the slots 108 in accordance with the scales 110, made'on the surface of the handles'100 and 101, which indicate the diameter of the armature for which the coil is. intended; the scale number is started at the pivotal oint of connection of the stationary coil hdlding member and the laterally movable coil expanding memplivotal point to be the t e armature or of the \Slidable on the shaft 92, and rotatable independently thereof are brackets 111 and 112. ,These brackets are'frfee to slide inwardly, but one of'them may be restrained against outward sliding movements by meansof a collar 113, which is secured inselected positions on theshaft by means of a set screw 114. These brackets, each, carry a coil holding knuckle 116 and 117 respectively, that are vertically adjustable in slots 118, 119, respec-* tively, and that are held in place by means of screws 120, which take through the slots into the knuckles. These knuckles are provided with vertically extendin slots 121, for the reception of the ends of t e coil to be formed and each is provided with inwardly directed projections 122 and 123. The levers 100 and 101 are provided with handles 126-127 secured to the respective levers by means of bolts 128,129. v

The vertical dimensions of the rojections, or lips, 122 and 123 of the knuck es, 116 and 117, respectively, may be enlarged for making the nose of the coil longer. These knuckles may also be transposed; the knuckles changing places on the brackets 111 and 112, and this will result in increasing the length of the nose of the coil. For coils of smaller diameter, the knuckles may also be inverted so that the. active part of the knuckle may be madeto approach nearer the axis of the machine. When greater variations, in the length of the noseof the coil are required, as in rectangular coils, the adjustable form shown inFigs. 12 .and 13 may be employed wherein the plates 131 and 132 may be readily shifted in a vertical direction.

The modified knuckle, for forming square ended, or rectangular coils, illustrated in Figs. 13 to 15 inclusive, is shown in Figs. 5

and 6. In this case a plurality of holes, 130,

are provided in the side members 131, 132, for reception of ins 124, of which two are required for each knuckle, which pins are inserted in one plate at 'the offset, and in the other plate in any one of the other holes. The side pieces 131, 132, are vertically adjustable, with reference to each other and to the main portion 116, by the slot 133, which is provided in each of the side pieces 131 and 132, and in the knuckles, by means of bolts an-epas 134:, which pass through the arts. An offset, 135, is provided in eac of the side pieces, one being above and the other below the median line thereof, as shown in dotted lines, in Fig. 5 and in the holes nearest these offsets, the pins are inserted. The knuckle may be free y turned on the bolt 120 except when restrained by a removable pin 120'- for changin the angle of the nose with reference to 518 side portions of the coils.

When a coil has been wound, as shown in Fig. 7, and properly taped, and it is desired that it shall then be formed into the sha e substantially as shown in Figs. 8 and 9, t e notch 107, in the forming brackets 105, is adjusted, as much above the statlonary coil holding devices 87 as the u per longitudinal portion of the coil is a ove the lower portion thereof. The lower portion of the coil is then placed in the notches 91-91 of the stationary holding devices 8787 and the upper portion is placed in the notches 107107 of the movable forming brackets 105-106 and the curved ends are placed in the notches 121121 provi ded in the knuckles 116-117 of the brackets 111, 112, which are freely rotatable upon the shaft 92, and then the pins 12 1-124 are inserted in the body portion of the knuckles so as to bridge the projections 122 and 123 and hold the coils securely in place as shown in Fig. 3. The forming frame, comprising the pivoted levers 100 and 101, and the handles 126 and 127, which carry the brackets 105 and 106, is then moved on the pivotal point, which is the shaft 92, to a position substantially, as shown in Fig. 3. As the forming portion is moved out the knuckles 111 and 112, move'inwardly and freely on the sup ortmg shaft 92, being drawn inwardly y means of the pins 124, as the coil is expanded in width and contracted in length.

In the position shown in Fig. 3, the body of the coil in slots 91-91, of a stationary coil holding bracket 87-87, is in a plane at substantlal right angles to the plane in which is the body of the coil shown in slot 107, of the bracket 105 and the end configuration of the coil is substantially that shown in Fig. 9, both ends of the coil being alike. If it is desired that the sides of the coil shall not lie in planes that are at right angles to each other, but at an angle less than right angles, then the coil expanding frame should be moved to a less degree than that shown in Fig. 3, and to this end I have provided an adjustable stop consisting of an adjustable plate 140 slotted as at 141 and secured in adjusted position by means of the cap screws 142-442 that take into the sides of the base plate 70. When this plate, 140, is raised and secured in selected position, it affords a means for stopping the levers 100, 101, and therefore afiords a means for controlling the extent to which the coil is expanded in the process of formfit will now be apparent that the configuration, and dimensions of the coil, as it will appear when placed upon the armature, or within the stator, of the dynamo electric machine is readily and directly determinable by indicating scales and indices that are placed upon the machine which determine the extent and the position to which the various parts of the machine must be moved preliminarily to formin the coils. By this means the artisan or t e user, of therespective device, having in mind the dimenslon of the armature or stator, for which the coils are to be provided readily adjust the machine by the scales readable in the terms of the dimensions thereof. This is an important feature of my invention as it avoids the necessity of mental calculation or consulting dimension tables, and prevents confusion in the adjustment of the machine.

When the knuckle 116' is used for forming rectangular coils, during the first part of the movement of the expanding frame, composed of the levers 100, 101, etc., it is restrained from pivotal movement on the bolt 120 by the pin 120' which enters the slot 119 in'bracket 111 and passes into a perforation made in the part 116 of the knuckle. After'sufiicient movement of the coil expanding means has been effected, pin 120' may be removed and the final or finishing coil expanding movement may be completed. This gives the proper conformation to the ends of the rectangular coil.

While I have herein described a single exemplification of my invention, in the various details for purpose of complete disclosure, it is obvious that many changes may be made in the specific constructions, without departing from the spirit and scope of the appended claims.
