Specification of Letters latentY Fatented Aug. 8, 1911.
To all whoml it may concern:
Be it known that I, HENRY E. LEPPERT, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Switches, of which t-he following is a full, clear, and exact description.
My invention relates to improvements in switches, more particularly to quick-acting switches, and has for its object to provide'a new and improved switch arm actuating mechanism dispensing with delicate parts and projections that are liable to be worn or broken. It is particularly applicable to switches in which the switch arm has a movement about anaxis.
The following is a description of an embodiment of myinvention, in its preferred form, in an oscillating push-button switch, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a two push button switch embodying my invention. Fig. 2 is a plan view of the same. Figs. y3 and 4 are sections on the line w--w Fig. 2, with the parts in two positions on enlarged scale. Fig, 5 is a side elevation of a detent and detent-carrying member. Figs. 6 and 7 are side and front elevations of the cam bearing member. Fig. 8 is a side elevation of the annular boss showing the holes containing the spacers.
Referring more particularly to the drawings, 1 is a portion of a porcelain base to which a standard 2 is secured. 0n this standard is formed an annular boss 3 having within it, in the case of an oscillating as distinguished from a rotary switch, two holes or recesses 4-4, extending through the ring. Inside the ring is a movable member 5, which in the embodiment shown has a recessl containing a bolt or detent 6, against which bears a spring 7 tending to move it Vtoward the annular boss. Outside the ring,
in the embodiment shown, is a movable member 8 having a cam surface 9, which coacts with spacers 10-10 in the holes 4--4. The
spacers are preferably in the form of balls, the length of the spacer or diameterof the ball being equal to the thickness of the wall of the annular member. To the cam bears lng surface 8 is connected actuating means, such means 1n the present instance cons1sting of push-bottoms 11-11. To the detent carrying member 5 a switch arm 12, insulated in the usual manner, is connected, the same being adapted to engage suitable statlonary circuit contacts (not shown). It is to be noted that in the embodiment shown the cam bearing member is on the outside of the boss 3 and the detent carrying member is on the inside thereof, this being the preferable arrangement when the invention 1s embodied in an oscillating switch. The two movable members 5 and 8 are connected by a coiled spring 13, whose ends engage opposite sides of two lugs 14-15, carriedby the two movable members respectively. The lugs at the limits of their throw engage stop faces 16 which are positioned so Athat vwhen the lug 15 engages either face the detent 6 will stop opposite one of the holes 4-4 in the annular boss, and when the lug 14 engages either of them, a low part of the cam surface 9 will stop opposite one of said holes or recesses. When the low 'surface 9 and `the detent 6 are oppositethe same hole 4 or 4 the detent enters the hole and forces the spacer therein outward so as to engage the low surface of the cam, as shown in Fig. 3 or Fig. 4. v
When the parts are in the positions shown in Fig. 3, and the cam member is moved counter-clockwise by the actuating means, the cam surface acts upon the spacer'l() in engagement therewith, moving it inward, together with the detent 6, until a high portion of the cam surface is in contact with the spacer, as 10, shown in Fig. 4, the position of the detent at thatv time beingshown in dotted lines in Fig. 4. The detent is thereby moved out of the hole in the annular boss into which it had been thrust by its d spring. The vdetent bearing member with its switch arm is thereby released and snaps counter-clockwise under the influence of the connecting spring, whichby the movement of the cam bearing surface was put under tension. When the detent member has thus snapped, the detent stops opposite the other Eis will be evident to those skilled 'in the art, my invent-ion permits or various modiiil cations Within the claims hereto appended and Without departinp,` :trom tbe spirit thereof.
What l claim is:
l. ln a switch, the combination of a sta-- tionary member havingl a plurality of recesses therein, two independently movable members on opposite sides tbereozt, one ot said movable members having a recess therein and the other having a cam surface, a springectuated detent in the recess in said one movable member and adapted'v to partially enter the recesses in said stationary member, spec Within the recesses in said stationary member enacting with said cam surface detent, and a spring connecting said tivo movable members.
2. ln :a svvitcb, the combination oit an annular stationary member having a plurality recesses, tvvo members,` one on the outside andthe otber on the inside of said annular member, independently movable aboutx be center et the stationary member I one or" said movable members "s and tbe other having a cam Angeactmrtod detent in the reone movable adapted to partially enter the recesses in said stationary' member, spacers Within the recesses ot said stationary member coacting With said cam surface and detent, a spring connecting said tivo movable members, and
tially enter the recesses in said stationary member, spacers within. the recesses in said stationary member coasting vvith said cam surface and detent, a spring connecting said t'Wo movable members', a rocking lever connected to said cam lsurface member, and push buttons connected to said lever.
et. ln a switch, the combination 'ot an annular stationary member having a plurality or recesses therein, a movable member within said annular member and having a recess, a second movable member provided With a'cam surface and mounted onthe outside or said annular member so as to move about the center thereotl as an axis, a spring actuated detent in the recess or said, iirst movable member and adapted to partially enter the recesses in said stationary member, spacers Within the recesses in said stationary member, coacting with 'said' detent member and and said cam surface, a spring` connecting said two movable members, and actuating means' connected to said cam surface member.
5. ln av switch, the combination of an annular stationary member having a plu*- rality ot recesses' therein, a movable mem- -ber Within said annular member and having;
