ELECTRIC SWITCH..
Application filed August 31, 1921. SerialNo. 497,162.
To all whom #may concern:
Be it known that we, CHARLES LEONARD AnNoLm a subject of `the King et Great Britain and ireland, and resident of Enlield, in the county of Middlesex, England, and
CHARLES REGINALD BnLiG, a subject of the King of Great Britain and Ireland, and resi-v dent of Enfield, in the county of Middlesex, England, have invented new and useful lmprovements in Electric Switches, of which the following is a speciiication.
This invention has relation to electric switches and it has for its object to provide improvements by which certain advantages shall be obtained.'
An electric switch, in accordance with this invention, comprises a pivotally mounted contact carrying member, a pivot-'ally mounted actuating member and a pivotally mounted third member which, on movement of the actuating member, is engaged thereby, moved therewith, and caused to engage and impart movement to the contact carrying member.
ln order that the invention, the nature of which has been set forth, may be clearly understood and readily be put into practice, reference will now be made to the accompanying sheet ot' drawings, on which?- Fig. 1 is a sectional elevational view, and
Fig. 2 a sectional plan View of one construction ot' switch;
Fig. 3 is a sectional elevational view, with the switch parts in the open position;
Fig. 4 an end elevational view;
Fig. 5 a sectional plan view; and
Fig. 6 a sectional elevational view, with the switch parts in the closed position, of a modified construction ot' switch.
1 is a framework of any suitable design and construction in which the movable parts of the electric switch are mounted and which also serves, in the two constructions illustrated, to carry the iixed contacts 2 of the switch. 'The framework 1 also serves for the mounting of the switch.
3 is a movable member carrying the contact 4. which co-operates with the fixed contacts 2. The member 3 is ot U-shapein plan, and is pivotally mounted at its open end on pins 5 carried by the side walls of the framework 1. The contact l is insulatingly mouhted on the closed end of the member 3.
6' is another movable member, also o U-shape in plan view and pivotally mounted at its open end on the pins 5 and between the arms of the member 3. i' is 'a handle mounted on the closed end of the member t5. 8 is a spring connected at one end with a pin 9 mounted in the side arms of the member 3 and at the other end with a pin i 10 mounted in the side arms of the member (i.
y11, 12 (Figs. 1 and 2) are two curved plates. |The plate' 11 is pivotally mounted on a pin 13 carried by one of the side walls ot the framework 1 and disposed towards the right hand uppercorner thereof. The plate p 12 is pivotally mounted on a pin 14 carried by the other of the side walls of: the frame work 1 and disposed towards the right hand lower corner thereof. The plates 11, 12 are of different shape. rlihe plate 11 carries two lugs or projections 15, 16 of which one, 15, extends above one side arm of the member 3 and the other, 16, below one side arm of the member 6. The plate 19. similarly has two lugs or' rejections 17, 18,'of which the lug 17 exten s below one side arm of the member 3 and the lug 18 above one side arm ot the member 6.
Theparts are shown in the open position of the switch. `When the handle 7 is pressed, the member 6y is caused to turn about its pivots 5 and to contact with the lug 16, The pressure on the lug 16 causesl the plate 11 to turn about its pivot 13 and the other lug 15 to contact with and press on the member 3, which, as a consequence, is constrained to move about its pivots 5 and move the contact 4 into engagement with the contacts 2. During and by the movements of the members 3, 6, the spring 8 is stressed and when the members have been moved to a positionin which they are just past the straight line the spring 8 tends to move to its retracted position. The retractile movement of the spring 8 causes the member 3 to more ih advance of the plate 1l and eti'ect a "quick make of the circuit. When the handle 7 is raised, the plete member 3 is moved aboutfits pivots through the plate 12, the lug 18 being acted on by one side arm of .the member 6 and the lug 17 contacting with and pressing on the member 3. The opening movement of the member 3 is completed quickly by the |The switch illustrated and descri d can beoperated without a spring 8, but when the spring is omitted, or becomes inoperring 8. l

ln the construction of switch illustrated in Figs. 3 to 6 inclusive, there is substituted for the plates 11, 12 a4 single plate 20 and pivotally mounted on a pin carried by,
one of* the' iside 4walls of the' framework 1 and having four lugs or projections 21, 22, 2.3, 241. The lugs 21, 23 which are disposed oppositely come, respectively, vabove and below the member 3 and the lugs 22, 9A,
which are also disposed oppositely, come above and below, respectively, the membei `6. It may, in some instances, be i'ound deltying lugs projecting' on opposite sides of,
and into the paths of movementl of, said members to transmit movement from the actuating member to the contact carrying member until the spring becomes operativen said third member being made in two parts, of which one 1s Operative on the opening movement 'and the other on the closing .movement of the switch.

5. An electric switch comprising a support, a switch plate pivoted therein, a switch lever pivoted yin said support adjacent the pivot of the 'switch plate the swil ch plate and the lever extending in opposite directions from their pi ots, a coil spring connecting the switch plate to said lever and arranged to pass across the pivotal points of said two parts, rigid stops for the switch plate n its on and off positions, contact arms carried by the switch plate, and a pair of kick-off levers pivoted in the support on opposite sides of the switch lever and adapted to be engaged and moved by the switch lever' to swing the switch plate on its pivot. 6. An electric' switch comprising aI suport, a switch plate pivoted therein, a switch ever pivoted therein, a coil spring connected to the lever and to the switch plate arranged parts, and a air of kickoff levers cooperating with t e switch lever to swing the switch plate on its pivot.
