3 Claims.
a helical coil winding machine having a rotatable drum upon which the coil is formed, and having power drive means including speed reduction means for forming the coils at high speed.
Still another object of the invention is to provide a helical coil winding machine which is simple in design, inexpensive to manufacture, and which is rapid and efifective in operation.
Other objects and advantages of the invention will become apparent from the following description of a preferred embodiment thereof as illustrated in the accompanying drawings, and in which,
Figure 1 is a side elevational view of my improved machine,
Figure 2 is a fragmentary front elevation of the device as seen from the left side of Figure 1,
Figure 3 is a horizontal sectional view taken on line 3-3 of Figure 1,
Figure 4 is a vertical sectional view taken on line 4-4 of Figure 1,
Figure 5 is a horizontal sectional view taken on line 5-5 of Figure 4,
Figure 6 is a face view of one of the helical coils formed in the machine, and
Figure 7 is a side elevation of the coil shown in Figure 6.
In order to understand clearly the nature of the invention and the best means for carrying it out, reference may now be had to the drawings, in which like reference characters denote similar parts throughout the several views. As shown, there is a base member ID supporting an upright post l2 having a lateral bore l4 for the reception of a bearing IS. A shaft I8 is journaled at its right hand end as seen in Figure 3 in the bearing I 6, and extends through the hub of a winding form drum 22, the hub being keyed on the shaft by means of a set screw 24.
The winding form drum 22 has a substantially cylindrical portion 26 with a right hand end annular flange 28, and its left hand portion 39 is conical between locations 32 and 34, the conical portion having continuous helical ribs 36, which furnish support for the wire which is to be wound on the form. The left hand end of the shaft I8 is laterally recessed at 38.
Rotatable mandrels 4B and 42 are keyed on rotatable shafts 44 and 46 which are journaled in bearings formed in support members 48 and 50 which are pivotally interconnected and supported upon a pivot pin 52 extending into the upright post Ill. The links 54 and 56 are pivotally connected by pin 58 at their upper ends and are connected by pivot pins 69 and 62 at their lower ends of the upper ends of the support members 48 and 50, a tension spring 64 serving to draw the members and their mandrels together out of contact with the inner face surface of the cylindrical drum 26.
The shafts 44 and 46 are rotated by means of sheaves 66 and 68 which are keyed on their outer ends, the sheaves being interconnected by means of a belt 10. A pull rod 12 is pinned at its upper end to pin 58 and is connected at its lower end to a treadle lever 14 having a pedal 16 and pivoted at 18, whereby depression of the pedal spreads the mandrels apart to engage the inner drum surface of the drum 26, to rotate it as the mandrels are rotated.
A larger sheave is also fast on the shaft 44 and is driven by means of a belt 82 also encircling the smaller sheave 84 which is fast on a shaft 86 and also carries a larger sheave 88 which is rotatable therewith. A power belt 90 encircles the sheave 88, and also the drive pulley of a motor, not shown, whereby the machine is operated. The diameters of the various sheaves are so arranged and related, that a motor having a relatively high speed, will have the speed reduced sufficiently for the purposes of the machine by the time it reaches the mandrels 40 and 42, which drive the winding drum.
The drum flange 28 has teeth 92 formed on its right end surface as seen in Figures 1 and 5, which are engageable by the arm 94 of a hinge dog 96 the stationary arm of which is secured to frame l2 by screws 98. A leaf spring I00 biases the arm 94 into engagement with the teeth 92.
In operation, the motor is started, driving the sheaves and rotating the mandrels. The wire to be wound has one end inserted into the projecting eye 94 on the conical drum, and then the pedal 15 is depressed, which expands the mandrels apart to engage the inner drum surface, rotating the drum,
and the wire is wound on the helical ribs 36 to-v ward the apex of the conical drum at 96. Then the pedal 16 is elevated, stopping the drum and the Wire is brought up around the left end of the shaft end- 96 as at 98 in Figure 6, and then bent across the recess 38 as at H30 in Figure 6.
The Wire is then bent along as at I02 and around eye Hi4, thence back along I08 and against the side of shaft end 96 and down on the opposite side alongiiltland. around eye I H); thence around as at 1 l2 and up onto the cylindrical portion 25 of the drum to wind the cylindrical portion I Id of the coil, which takes care of the extra wire which is to be extended to the top of the pole Although I have described a preferred embodiment of my invention in specific terms, it is to be understood that various changes may be made in size, shape, materials and arrangement departing from the spirit and scope of the invention as claimed.
