Specification of Letters Patent.
Patented Dec. 10, 1918.
Application filed August 1, 1917. Serial No. 183,999.
To all whom it may concern Be it known that I, Join: Nnwnnnnx' REY- NOLDS, a citizen of the United States, residing at Greenwich, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Methtudinally extending bare conductors which are divided into sets, each wire being provided with a plurality of longitudinally separated contact surfaces, the different wires comprising a set having their contact surfaces longitudinally separated from each other, while the corresponding wires of separate sets have their ontact surfaces in the same line transversely of the strip.
The object of this invention in general is to provide for the manufacture, in an efficient and economical manner, of a type of multiple contact strip outlined in the foregoing paragraph.
The process of this invention consists in general in forming a web consisting of bare conductors with insulating strips inserted therebetween to displace portions of the conductors relative to the normal plane thereof and at 1011 itudinally separated positions. The web so fin-med is clamped upon a mounting plate previously prepared with insulating compound and the conductors arefanned out at one end of the mounting plate and bent back upon themselves to form connecting terminals. In the final step of the process, the mounting strip with the web thereon is heat treated or baked to set said web in the insulating compound.
In the drawings illustrating this invention, Figures 1, 2, 3, 4, 5, 6, 7 and 8 are views illustrating the successive steps and apparatus entering into the process; and Fig. 9 is a fragmentary view of the finished product.
In the first step of the process of this invention a pluralltv of wires 7, 7, 8, 8 and 9, 9 (Fig. 1) are clamped at one end to a plate 10, over which the extend longitudinally and are laced un er tension by suitable means suc as weights 11, 11. The face of the plate 10 over which the wires 7, 7,
8, 8 and 9, 9 extend is provided between its ends with a plurality of equally spaced transversely extending depressions 12, 12. A presser roller 13 is provided on its face with a plurality of circumferentially arranged pro1ect1ons 14, 14 adapted as said roller 13 is, moved over the plate 10 to depress two out of each three wires into the depressions 12, 12 of said plate. The projections 14, 14 of the presser roller 13 are arranged in pairs, each pair having its projections circumferentlally separated from each other to such a distance that they engage the wires upon which they act, at points near opposite sides of the depression 12 to permit of the insertion of an insulatin strip 15, 16 Or 17, as the case. may be. T 1e insulating strips 15, 16 and 17 are each provided with notches 20, 20 in their edges adapted to be engaged by the undepressed portion of one of the conductors 7, .7, 8,. 8 or 9, 9. The notching of the several strips 15, 16 and 17 being such that when they are inserted between the wlres, the wires 7 7 will be in the notches of the strips 15, the wires 8, 8 in the notches of strips 16 and the wires 9, 9 in the notches of strips 17. For convenience these strips 15, 16 and 17 may be arranged in three piles in a magazine 21 and moved one by one into ahopper 22 by means of slides 23, 24 and 25. From the hopper 22 they may be separately inserted between the wires by means of a slide 26.
After the wires 7, 7, 8, 8 and 9, 9 have been stretched over the plate 10, the presser roller 13 is passed thereover from right to left. In its first position it will depress all of the wires 7, 7 and 9, 9 into the corresponding depression 12 in the plate 10 and an insulating strip 15 will be inserted between the relatively depressed wires. In the second position of the roller 13 all of the wires 7, 7 and 8, 8 will be depressed and an insulating strip 16inserted between the relatively dis laced wires, and in the third position,of tlie roller 13 all of the wires 8, 8 and9, 9 will be depressed, and an insulatin strip 17 will be inserted between the relatively displaced wires. In its fourth position the roller 13 will have made a complete revolution and the, operation above stated Will be continued until the web of wires and insulating strips'is of the length desired.
When the web has attained the desired length in the manner above described, a
Clamping means comprising aclampmg plate 40 (Figs. 7 and 8) which is-placed over the insulating blOCii 37, and screw clamps 41 and 42 are applied to secure the mounting strip 30 and the block 37 together temporarily. With these parts clamped together the steel block 35 and the terminal forming block 36 are removed and the comb 32 is lowered until the wires are drawn in beyond the end of the formed strip into their normal positions. A clamping block 45 is next applied to the wires beyond the formed strip and the wires are cut at 46. The formed strip is then placed in the oven and baked for the required period of time. After having been baked to set the web in the insulating material, the strip may be removed from the oven and the wire stubs, which were left when the cut was made at 46. may be cut oil adjacent to the block 37.
While the process of this invention is shown and described in connection with a terminal strip' adapted for three conductor circuits, it will be obvious to those skilled in the art to which this invention relates that the process of the invention may be applied to the manufacture of strips for circuits of any number of conductors.
