SWITCH AND HOUSING CONSTRUCTION THEREFOR.

Application flied May 3,

To all 'whom t may concern:

Be it known that I, CARL H. BIssELL, a citizen of the United States, and a resident of Syracuse, in the county oi'. Onondaga and State of New York, have invented a certain new and useful Switch and Housing Construction Therefor, of which the followingr is a specification..

This invention has for its object a. switch and housing construction therefor particularly applicable for use in connection with electric headlights of locomotive, electric cars, etc., where ruggedness and simplicity are factors, which construction is .especially simple and highly efficient and durable.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

ln describing this invention. reference had to the accompanying drawings in which like characters designate correspondingr parte in all the views.

Figure 1 is a front elevation, partly in section, of a switch embodyingl my invention, the box therefor being shown in section and the cover of the box as brokenv away.

Figure 2 is a. vertical sectional view taken centrally or' Fig. 1.

Figu re 3 is ay front elevation of the entire switch construction includingV the housing therefor.

This invention comprises a` switch having; movable member or switch arm.` a handle connected t0 said member and having' a movement in a direction at an angle to the shitting: movement of the handle, a springt tor efiecting such movement. and a. sum".r against which the springr holds the handle.

l designates the hoX in which the switch housed, said box having means as one or more nipples 2 Yfor connection to conduits enclosingr the service wires. The box' is open at its front side and said side provided with a cover 2 secured in position in any suitable manner as by screws It.

The switch here shown is a double throw knife switch and comprises a hase 5 of iii-- sulation mounted in the box ou one of the walls adjacent the open side. contacts 6. T mounted near opposite ends of the base. a conductor 8 mounted on the base between the contacts, a` switch member or arm Sa hinged to the conductor and movable into 1919. Serial No. 294,581.

engagement with either`contact 6, 7 and a handle 9 for operating the arm 8a.

The base is secured to the boX in any suitable manner, as by screws 10. The con* tacts 6, 7 are knife contacts and are held in position in any suitable manner as by screws 11.

The conductor 8 is Z-shaped in general form, the base of the Z .being mounted on the base 1 and secured thereto as by screws 12 extending from the rear side of the base. One arm of the Z-shaped conductor is provided with a binding device 13.

The binding device 13 is for connection to a feed wire, not shown, by means of which the current is carried from the feed wire'to he conductor 8 to one branch of the switch arm S, thence to the other arm to one of the contacts (i. 7, when the switch is closed. the arm 6^ being' U-shaped in order to proride two conductors, one of which coacts with the conductor 8 and the other with the switch contact 6 or 7.

The switch member 8Pl is here shown as U-shaped and the arms thereof are pivoted to the arms ot the conductor 8 by a hinrfc pin. 14. and one of the arms of the switch member is movable into and out of engagement with the contacts 6, 7. The switch member normally stands in neutral position and is moved to neutral position from either side ot neutral by a spring 15 coiled about theI hinge pin 14- and having its ends bearing respectively on opposite edges of the arms of the U-shapcd switch member.

The handle 9 is practically a crank handle mounted on the switch member and havingr a yielding movement at an angle to the movement of the switch arm, that is the handle vis movable radiallyrelatively to the airis of the switch member.

ln the illustrated form of my switch, the handle extends through a radial slot 16 in the trent arm oi' the switch member and is pivoted at its inner end to a lug 17 carried by the intermediate part of the switch arm and spaced apart from the front arm.

The handle 9 is moved inwardly radially bv a spring 1S connected at one end to the handle` and at its other end to the hinge pin 14.

The handle projects through a slot 19 in the cover 3. Shoulders 20 project into the slot neal` its opposite ends forming sockets or :seats 2l into which the handle ratehets when shifted, in one direction or the other to engage the knife or switch member' with either eontsicts (i or '7; rlhe springY 18 pulls the handle against the upper side the slot and ratchets it in the seat This` switch is particularly applicable for lighting and dimmingheadlights and in operation7 when the handle is moved in one direction from central position, the switch arm engages the contacts 6 to lgive ii'ull light and when moved in the opposite direction from neutral engages the contacts 7 to dim the light. During; the movement of the handle it ratcliets automatically into one or the other of the seats 2l.` i

Tl". switch construction particularly advantageous in that it is simple,Y Strong and Weather tight and further in that it pro* vides en especially simple look ttor holding the switch in its operative posit-iene What l Claim is:

l. ln a snf'itch, the combination oit e movable member, a spring acting on 'the movable member to give the seine a snap action, a handle having` movement relativelyI to said member, e springactingv on the handle to move the same relatively to said member, and a part 'lormed with :i shoulder arranged `in the path ot the handle` the spring beine,` arranged to move the handle into engagement with said shoiilden substantially es and for the purpose described.
