CON TACT-BANK.
Specification of Letters Patent. Paigefltefl 18 5320, 1918,
Application filed September 25, 1915. Serial No. 52,659.
To all whom it may concern:
Be it known that I, HENRY P. CLAUsnN, a citizen of the United States, residing at Mount Vernon, in the county of Westchester and State of New York, have invented cer-* tain new and useful Improvements in Contact-Banks, of which the following is a full, clear, concise, and exact description.
This invention relates to contact banks for automatic switches of the rotary type.
One of the objects of the invention is the provision of a panel bank wherein the cor responding contacts at the same level in a series or row of switches are all formed as in tegral projections of a terminal strip or bar.
Another object of the invention is the provision of a bank, as above, which has contacts projecting from its opposite faces so as to be accessible to switches on either side.
A further object of the invention is the provision of a contact bank having contacts arranged on its opposite faces in which the contacts of the lines on both sides appear in the same relative order in the direction of rotation of the switches.
A still further object of the invention is the provision of a bank in which the terminal strips and the contacts are arranged in pairs.
Referring to the drawing, Figure 1. is a plan view of the contact bank with contacts projecting from one side thereof; Fig. 2 is a cross-section on the line 22 of Fig. 1; Fig. 3 is a plan view of the bars and contacts showing the manner of offsetting certain of the contacts in order to bring the contacts on opposite sides into alinement; and Fig. 4k is a detached view showing merely the first and last sets of contacts and bars in Fig. 3.
It will be seen from Figs. 3 and 4 that the pairs of bars 1 and 2, from which the contacts 3 and 4 projecting downwardly at the left are formed, are the same bars as those from which the contacts 5 and 6, extending upwardly at the right, are formed. As the direction of rotation of a switch is usually from left to right, or in a clockwise direction, it will be seen that as contacts 3 and 4 are the first to be engaged by the switch as sociated therewith, in a like manner the contacts 5 and 6 will be first to be engaged by the switch associated with them.
From an examination of Fig. 3, it will be noted that the second set from the left of downwardly projecting contacts are formed from the same strips as the second set from the right of upwardly projecting contacts and so on, the last set projecting downwardly at the right being formed from the same bars as the set projecting upwardly at the left. Thus, the line contacts will appear in the same order on both sides of the in the switch, it is preferable to arrange the terminal strips in pairs and arrange the two contacts of a set one above the other, as clearly shown in Fig. 4. As thus arranged, the contacts will be engaged by brushes on their non-adjacent sides as indicated in the drawings.
In order to bring the contacts on opposite sides of the switch into alinement, it is necessary that the projecting portions, forming the contact terminals of certain line strips, be offset. The manner in which this is accomplished is clearly illustrated in Figs. 3 and 4t, and it is believed it will be readily understood without further description.
Strips 7 of metal, as copper, are placed between the pairs of terminal strips to form shields to prevent crosstalk.
Where a contact bank of the above described character is employed with an upand-around switch, the contact rows at the different levels would be formed independently and mounted in any desired manner, one above the other, with the corresponding terminals in alinement.
What is claimed is:
1. In a contact bank for switching devices, terminal strips arranged side by side in a row, said row extending in a plane at an angle to the side of said bank facing the switches, and contacts integral with each of said strips projecting from the side of said bank facing the switches.
2. In a contact bank for switching devices, terminal strips arranged side by side in a row, said row extending in a plane at an angle t0 the side of said bank facing the switches. and contacts integral with each of said strips projecting in a row from the side of said bank facing the switches.
3. In a contact bank for switching devices, terminal strips arranged side by side in a row, said row extending in a plane at an angle to the side of said bank facing the switches, and'contacts integral with each of said strips projecting from opposite sides of said bank.
4. In a contact bank for switching devices, terminal strips arranged side by side in a row, said row extending in a plane at an angle to the side of said bank facing the switches, and contacts integral with each of said strips projecting from opposite sides of said bank, the corresponding contacts on opposite side of the bank being formed from the same strip and arranged in the same relative position to each other.
In witness whereof, I hereunto subscribe my name this 24th day of September A. D.,
HENRY PETER CLAUSEN.
