This invention relates to improvements in equipment for the attachment of terminal wires to the leads of electrical coils.

An object of the invention is to facilitate manual operations by which permanent connections are made between the respective leads of an electrical coil and the terminal wires therefor.

Other objects and advantages of the invention will appear hereinafter.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which v Fig. 1 is a plan view showing an of parts belonging to the invention;

Fig. 2 is a side elevation projected from Fig. 1, partly in section;

Fig. 3 is a front elevation of the lead holder and severing device; and

Fig. 4 is a plan view of the leadholder and severing device. v

Referring to Figs. 1 and 2 of the drawings, there is disclosed an assemblage of members consisting of a bench 1 having a forwardly extending shelf 2; a coil holder consisting of a cradle 3 supported upon a post f that surmounts the shelf; a pair of water pots 5 disposed one upon each side of the cradle, there being corresponding brackets 6 ,for the water pots, and a block 7 on the post from which the brackets extend; a lead holder 8 and lead severing device 9 disposed at the front end of the shelf 2; and a solder pot 10 located at a point between the coil holder and the lead severing device. Upon the bench, located beyond the cradle 3 conveniently are positioned a pair of partitioned pans in each of which are separately held, a supply of flux 26 and glycerine 27, or similar materials.

The cradle 3 of the-coil holder is preferably shaped sothat when a coil placed therein, it will be held inert by its own weight, and they water pots 5 preferably ensemble are of such miniature proportions and are so i I 7 connection wlth one end of a-beam 49, the

such that when the leads are stretched out a vertically movable post that extends 30 (Fig. 2) is P The terminalholder 8 (Figs. 3 and 1) consists of a pair of spaced jaws 31 fixed upon a bracket 32, and a lever 33 supported by a bolt 34L that extends through said bracket, the lever having a tongue 35 that is projected between the jaws 31 when the lever is in normal position. *A retracting spring 36 is secured at one end to a post 37 and at its opposite end to an arm 38 on the lever, wherebythe le ver normally is held with its tongue 35 between the jaws 31. The lever 33 has. a handle 39 by which it may be manipulated to withdraw the tongue from the jaws and thus permit insertion of the leads 40, of the coil, betweenthe tongue and jaws, which leads are anchored in the holder upon release of the handle. v

The, severing device 9 consists of a series of knife blades 41 secured to a bracket'42 having a slotted foot 43 that is adjustably positioned on the shelf 2, there being screws The blades 41 are disposed side by side, the cutting edge ofone blade being convergent with'respect to the cutting edge of thenext blade adjacent thereto, which cutting edges meet, or slightly overlap, at points spaced from the tips of The positions of the blades are from the coil 30 in the cradle 3, and are anchored in the lead holder, they extend be- ,tweenthe corresponding blades and lightly contact with the cutting edges thereof. 7

The-solder pct 10 is'mounted on the top of loosely through the-shelf 2., and conveniently is of the electrically heated type, conductors 16 being provided for supplying current from a suitable source of energy for heating the ot. The lower end of the post 45 is fixed on a block 4.-7 'that has a horizontally disposed pipe l8 attached thereto through which the conductors extend. The block 47 has pivotal point beneaththe block 47, and basal; its

'. minal wires to the leads of the coils.

other end pivotal connection with a slide 53 that is loosely mounted on the pipe 48.

An operating lever 54 is pivoted on the bracket 50 and is connected at one of its ends with said beams 49 and 52 at points thereon midway between their ends by means of a link 55, there being a spring 56 disposed 1n connection with the lever 54 tending to restrain its movement so that the solder pot is held normally in its lowermost position spaced suitably distant from the leads 40 to permit unobstructed movement of the fingers of the artisan in attaching the terminal wires to the leads.

When the lever 54 is tilted upon its fulcrum 57 in opposition to the restraint of the spring, the beams 49 and 52 are actuated through the medium of the link 55, and the solder pot is thereby elevated. Conveniently, a pedal 58 is attached to the lever 54 by means of a connecting rod 59, for actuatin g the lever.

In utilizing the assembly described, the leads 40 of a coil 30 are first drawn out and stripped of their covering of insulating mate rial, after which the coil is laid in the cradle 3, and the cleaned leads are stretched ferwardly between the blades 41 of the severing device 9 and anchored in the holder 8.

Flux 26 is applied to the wires by dipping their ends into the pans 25 in which the flux is contained. During this operation the artisan moistens his fingers and thumbs with the glycerine 27, or other suitable reagent, by which injurious effects of the flux upon the hands of the artisan are averted. The terminal wires are then applied to the leads 40 by the artisan, simultaneously, both hands being used, one in applying one of the wires to the one lead, and the other in applying the other wire to its lead, the operations consist ing in bearing downwardly upon the leads so that they are severed by the blades 41 and their surplusage thus removed, and then entwining the leads about their respective terininal wires by rolling them between the thumbs and fingers. The ends of the terminal wires having the leads entwined thereon are immersed in the solder pot'vv'hich is elevated by applying pressure to the pedal 58, and immediately. thereafter the soldered joints are plunged into the corresponding water pots 5 and thereby chilled to cause the soldered connections to quickly set.

The coil 30 is then removed from the cradle and finished by applying tubes, stickers or pieces of tape and labels in such manner as may be required, the terminal wires being bound to the body of the coil by the tape and stickers so that the wires extend from such points on the coil as desired.
