UNITED STATES PATENT OFFICE.

JOHN N. REYNOLDS, OF GREENWICH, CONNECTICUT, ASSIG-NOR, BY MESNE ASSIGN- MENTS, TO WESTERN ELECTRIC COMPANY, INCORPORATED, A CORPORATION OF NEW YORK.

TERMINAL BANK.

Specification of Letters Patent.

Patented Feb, 26, 1918.

Application filed September 17, 1915. Serial No. 51,259.

To all whom it may concern:

Be it known that'I, JOHN NEWBERRY RnYNoLns, 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 Terminal Banks, of which the following is a full, clear, concise, and exact description.

This invention relates to contact banks for switches of the panel type.

One of the objects of the invention is the provision of a contact bank in which the projecting switch contacts are formed as integral rebent portions of line terminal wires or strips.

Another object ofthe invention is to so twist or cross the Wiresor strips forming the terminals of a group of conductors individualto a line that inductive action will be prevented and crosstalk will thus be avoided.

A further feature of the invention is the provision of a panel bank having the above advantages in which the contacts will be arranged on opposite sides thereof.

Referring to the drawing, Figure 1 is a plan view of a section of the panel bank.

of the above described character; Fig. 2 shows a modification of the bank shown in Fig. 1; Fig. 3 is a similar view of another modification; Fig. 4 is a similar view of still another modification; and Fig. 5 is a face view showing the arrangement of the contacts of the modification shown in Fig. 4.

Referring first to Fig. 1, it will be noted that; all the contacts of the several sets shown thereon are formed as projecting or rebent portions of two pairs of terminal wires 1, 2 and 3, 4. The contacts 1, 1 1 1, etc., are all formed as projecting or rebent portions of the wire 1, and the contacts 2, 2 etc., are formed as similar integral portions of the wire 2. Likewise the contacts 3, 1, etc., are formed from the strips 3 and 4 respectively.

The contact bank shown in Fig. 1 is designed to be used with a structure such as that shown in Patent 1,172,585, issued February 22, 1916, to Henry F. Dobbin, and the series or rows of contact sets are so arranged that the same switch may traverse I either one or the other of a pair of adjacent would be in a companion row or series with the set of terminals 3 and 1, and would be positioned at the same relative position in the series.

The twisted arrangement of the terminal wires, as herein shown, effectually prevents all crosstalk. It is, of course, to be understood that the wires or strips are coated with an insulating substance, such as enamel or shellac, before they are formed into a terminal set. The coating may afterward be removed from the projecting 'or contact portions in any desired manner.

In Fig. 2, a bank is shown' in which there are three contacts in a set and consequently three terminal strips or wires 5, 6 and 7, the contacts 5', 5 and 5 being formed as rebent or projecting portions of the wire 5, while contacts 6, 7 etc., are formed as rebent portions of the wires 6 and 7 respectively.

In Fig.3 is shown a portion of a bank similar to that shown in Fig. 1 with the exception that the rows of contact sets are separated from each other and do not occur in pairs. In this bank, contacts 8, 8 etc., are formed from the wine 8, while the contacts 9, 9 etc., are formed from the wire 9. In Fig. 4 is shown a bank designed for use with a switch such as shown in Patent- 1,122,642, issued December 29, 1914, to John N. Reynolds. In this modification the contacts 10, 11 and 12, etc., are formed from.

the wires 10, 11 and 12 respectively It is thought that this figure taken with ig. 5 is self-explanatory and need not be further described.

In the completed bank the individual groups or sets of terminal strips will be insulatively mounted one above the other in a bank with the similar terminals of the several groups arranged in rows. This is preferably accomplished by inserting the strips in a mold with only the contact portions projecting therefrom, and then casting or pouring the molten insulating material about the body portions of the strips. If desired, however, the bank may be built up in a manner similar to that disclosed in Patent 1,127,741 issued February 9, 1915, to Amos F. Dixon.

What is claimed is:

1. A terminal bank for switches comprising a plurality of longitudinally extending separated. conductors, each conductor being provided between its ends with a plurality of contact surfaces projecting therefrom, and a mounting strip in which said conductors are secured in non-inductive relation to each other.

2-. A terminal bank for switches compris ing a plurality of longitudinally extending COILdUGtOIS,Q&C/h conductor being provided between its ends with a plurality of integrally formed contact surfaces projecting therefrom, and a mounting strip in which said conductors are secured in non-inducti'v'e relation to each other with the contact surfaces thereof projecting from said strip.

3. A terminal bank for switches comprising a mounting strip, and a plurality of longitudinally extending bare conductors embedded in said strip in a non-inductive and non-conductive relation to each other, each of said conductors being provided with a plurality of contact surfaces between its ends projecting from said strip.

4. In a terminal bank, the combination of sets of twisted conductors embedded in a solid mass of insulating material, and sets of multiple contacts integral with said conductors.

5. In a terminal bank, a pair of wires having integral projecting contact portions, said wires being transposed and embedded in an insulating compound so that the contact portions project from the face of the bank.

In witness whereof, I hereunto subscribe my name this 16th day of September A. D.,

JOHN N. REYNOLDS.
