ELECTRIC SWITCH,
Application filed December 10, 1923. Serial No. 679,760.
"and particularly to disconnecting switches for high voltage lines, and its object is to provide a simple easily operated switch,
with switch blades operated in a vertical plane in alignment with the axis of the supporting insulators, and with a positive op-' eration of the blade by means of the rota-- tion of the blade supporting" insulator.
I attain this object by the device d escribed inthe specifications and claims appended hereto. The features of "construction and mode of operation areillustrated and in whichp Figure I is a side elevation of a switch embodying;v the novel features of "my invention, shown in the closed position. Figure II is a plan view of the portion of the switch supported on the rotating insulator, and Figure III is. a sectional vlew on line 3 of Figure I of the assembly of bearing. trunnion, shaft, bevel gears and insulator cap as shown in plan view in FigureII. Similar numbers refer to similar parts in the three views.
In my design, 1 is a suitable supporting base; 2 is an insulator fixedly attached thereto; 3 is a bearing; 4 is a second insulator capable of rotating in the bearing 3,
preferably by means of a lever 5; 6 is a third insulator fixedly attached to the base 1; 7 is a contact, of any suitable design to receive a switch blade, fixed in position on the insulator 2; 8 is a switch blade of suitable design to which is firmly attached a bevel gear 9, which co-operates with a bevel gear 10, firmly attached to the rotating insulator 4; bearing'll supports the trunnion shaft 12 of the blade 8, and is supported on the insulator 4 in such a fashion as to permit the insulator to rotate without rotating the bearing 11; and rotation of bearing 11 is prevented by the strut 13 which is fastened to the insulator 6 by some suitable means, such as the support, 14 the strut 13 and the bearing 11 forming a T-shaped structure.
In my application I do not confine myself to the operation of this switch as a single pole unit, but embody 'in the design the arrangement of several such units to form a multipole switch. q In the operation of. my device, the rotating insulator 4is moved through a portion of a revolution by the operation of suitable mechanical connection such as t e lever 5. The bevel gear 10 being firmly attached to the rotating insulator cooperates with the bevel gear 9 to swing the switc1 blade 8 in an arcual path, raising'it from the contact on a radius fixed by the shaft .12 and so disconnecting the electric circuit.
Rotation of the insulator in the opposite .direction accomplishes the closing of the switch.-
I regard this as an improvement over existlng designs, In that the rotation of the ment with the fixed contact, thus permitting the support of choke coils, fuse tubes and other auxiliary apparatus upon the fixed insulator 6. 1
I do "not confine myself to the precise 'mechanical details shown in the drawings attached, but intend in my claims to cover all changes and modifications which may still embody the novel features of my device.
What I claim is:
1. In a circuit controller, a rotary insulator, a blade rotatable about an axis at an -angleto that ofthe insulator, and means for transmitting the motion of the insulator to the blade, including a stationary bearing on which the blade is pivoted, said bearing having an aperture accommodating a portion of the insulator rotating structure, a shaft for the blade carried by the bearing,
a strut engaging the bearing for holding- \t against movement, a bevel gear on the;
rotary insulator and .a gear on said shaft outside of the bearing in mesh with said bevel gear.
2. In a circuit controller, a rotatable insulating standard, said standard having a pro-- jection at one end, a stationary bearing having an aperture engaged by said projec -,L.] tion, a shaft projecting beyond said bearing at both ends, and having an axis atan angle to that of the standard, a stationary insulator, a strut extending between said insulator and the bearing, a bifurcated contact blade mounted on the shaft, and a pair of intermeshing bevel gears, one supported omtheblade coaxially with the shaft and outside of the bearing, and the other on the rotating standard and coaxially therewith.
3. In a circuit controller, a stationary insulator, a T-shaped strut fixed thereon having an aperture, a rotary insulator having a projection extending into said aperture, ashaft within the cross-piece of said T-shaped strut positioned at an angle to the axis of said rotary insulator, a bifurouted blade mounted on said shaft and means for transmitting the motion of said rotary insulator to said blade. I
4. In a circuit controller, a stationary inv sulator, a T-shaped strut fixed thereon having an aperture, a rotary insulator having a projection extending into said aperture, a shaft within the cross-piece of said T-shaped strut positioned at an angle to the axis of saidrotary insulator, a bifurcated blade mounted on said shaft and means for .transmitting the motion of said rotary insulator to said blade, comprising a bevel gear on the rotary insulator and a gear on one end of said shaft in mesh with said bevel gear;
In witness whereof, I have hereunto set my hand this 16th day of November, 1923.
