UNITED STATES PATENT OFFICE.
FRANK P. LAWLEB, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR T0 GENERAL ELEC- TRIO COMPANY, A CORPORATION OF NEW YORK.
HIGH-TENSION SWITCH.
Application filed July 9, 1924, Serial No. 725,048. Renewed June 25, 1927.
My invention relates to improvements in high tension switch mechanisms of the general type disposed in my Letters Patent No. 1,464,368, dated August 7 1923, reissued May 13. 1924, No. 15.838, and in my copending application Serial No. 725,049, filed July The objects of my invention are to provide an improved arrangement for protecting the operating parts of a high tension switch mechanism of the type disclosed in my Let ters Patent aforesaid, from the weather, and to provide an improved form of power line grounding switch arranged to cooperate therewith.
My invention will be better undelstood on reference to the following description when considered in connection with the accompanying drawing and its scope will be pointed out in the appended claims.
Referring to the drawing, Fig. 1 shows a circuit control mechanism or switch in which my invention has been embodied, and Figs. 2 and 3 show certain details of the arrangement shown in Fig. 1.
Fig. 1 shows line sections 1 and 2 arranged to be interconnected through line terminals 3 and 4, fixed contact 5, movable contact 6 and a yieldable connection comprising a member 7 pivoted at 8 and a member 9 pivoted at 10 and hinged to the member 7 at 11. It will be apparent that any suitable form of yieldable connection may be used to interconnect the movable contact 6. with the line terminal 4. The'line sections 1 and 2 are supported through dead end insulators 12 and 13 respectively attached to opposite ends or a trackway 13. Insulators 14 and 15 are provided at opposite ends of the trackway.
13 for the purpose of insulating and sup porting the line terminals 3 and 4 respectively. The movable contact 6 is mounted on an insulator 16, which is supported by a carriage adapted to move along the trackway 13. As will be apparent, upon consideration of Figs. 2 and 3, the carriage is underhung to permit the placing of a cover 17 above the trackway 13 and the driving gear of the carriage. A sprocket chain 18 arranged to cooperate with the sprocket gear 19 is attached to the carriage at 20. A wire or rope 21 supported by the idler pulley 22 is attached to the :car at 23 and to the chain 18 at 24. Any suitable means may be provided to rotate the shaft 25 of the sprocket gear. 19
grounding device may be provided for grounding the movable contact 6 in its open position.
The details of the arrangement shown in Fig. 1 will be better understood on reference to Figs. 2 and 3. It will be observed that the carriage is built up of parts comprising a yoke member 28. base members 29 bolted to the lower edges of the yoke member 28, and channel members 30 bolted to the carriage bearings 31. The members 29 are also attached to the bearings 31 by means of bolts 32. In this manner the carriage is under hung from its axles The channel members 13 are arranged to form a trackway for the carriage wheels 34. Roller guides 35 attached to the bearing 31 are provided for preventing lateral movement of the insulator 16, which is shown as mounted on the yoke member 28. A support 36 mounted on the channel members 30 may be provided for suspending the movable insulator from the carriage in cases where this construction is desirable.
I have explained my invention by illustrating and describing a specific embodiment thereof, but it will be readily understood by those skilled in the art that the structure of this embodiment may .be modified in certain of its details. I, accordingly, do not wish to be restricted, to the particular form of construction disclosed herein by way of example, for the purpose of setting forth my invention in accordance with the patent statutes. The terms of the appended claims are,
therefore, not restricted to the precise structure disclosed, but are intended to cover all changes within the true spirit and scope of my invention.
What I claim as new and desire to secure by Letters Patent of the United States is 1. A circuit control mechanism wherein line terminals are arranged to be interconnectedthrough a, fixed contact and a movable contact adapted to engage said fixed contact in its closed position and wherein a trackway and a carriage movable along said trackway are provided for moving said movable contact to and fro between its open and closed positions, characterized by the fact that said carriage comprises means suspended from and extending over said trackway to afiord a support for said movable contact.
2. A circuit control mechanism wherein line terminals are arranged to be interconnected through a-fixed contact and a movable contact adapted to engage said fixed contact in its closed position, comprising a trackway, a cover extending over said trackway, and a carriage movable along said trackway to move said movable contact to I and fro between its open and closed positions, said carriage having a yoke member extending over said trackway and said cover to afford a support for said movable contact, and means suspended from said carriage for supporting said yoke member.
3. A circuit control mechanism wherein line terminals are arranged to be interconnected through a fixed contact and a movable contact adapted to engage said fixed contact in its closed position, comprising a trackway, a cover extending over said trackway, a grounding switch arranged to lie upon said cover in its open position, and acarriage including means suspended from and extending over said trackway for supporting said movable contact and moving it to and fro between its open and closed positions.
4. A circuit control mechanism wherein line terminals are arranged to be interconnected through a fixed contact and a movable contact adapted to engage said fixed contact in its closed position, comprising a trackway, a cover extending over said trackway, a rounding switch pivoted at o posite sides 0 said'trackway and arrange to lie upon said cover in its open position, and a carriage movable along said trackway to move said movable contact to and fro between its open and closed positions, said carriage being provided with a member extendiikg over sald'trackway and said cover to a 0rd a support for said movable contact, and base members suspended from said carriage for supporting said movable contact supporting member.
5. A circuit control mechanism comprising line terminals arranged to'be interconnected'through a fixed contact and a mov able contact, an insulator for supporting said movable contact, operating means for supporting and moving said insulator rectilinearly to cause engagement and disengagement betweensaid fixed and movable contacts, and a cover extending over and protecting said operating means from the weather, said insulator being arranged above said cover.
In witness whereof, I have hereunto set my hand this 27th day of June, 1924.
