Specification of Letters Patent.
Patented Dec. 29, 1908.
Application filed 8eptember 12, 1908. Serial No. 452,778.
To all whom it may concern:
Be it known that I, LEMBERT H. MoUL- THROP, a citizen of the United States of America, residing in the city of Bridgeport, in the county of Fairfield, in the State of Connecticut, have invented a certain new and Improved Switch, of which the following is a specification.
The object of my invention is to provide a simple and eflicient switch mechanism particluarly with reference to the escapement for the contact member.
In the accompanying drawing, Figure 1 is a side elevation of the operating mechanism of the switch; and Fig.2 is a vertical section thereof.
The present invention will be readily understood by those skilled in the art, without illustrating the usual porcelain case and its common accessories, and I have accordingly shown merely the yoke or cross bar A carrying the standard 13 on which the switch mechanism is supported through the spindle C. On one end of the latter I mount the oscillating contact member 10, adapted to make and break contact with the terminals (not shown) carried by the porcelain case. A lug 11 extends from the contact piece 10 through the guide slot 12. in the standard B, and the latter thus limits the extent of the oscillation of said contact piece. The spring 13 coiled on the s indle C, actuates the contact piece'throug the depending ends 14: and 14 which embrace the lug 11. The rock lever 15 to the opposite ends of which the shanks of the push buttons 16 and 17 are pivoted, is also rovided with a lug 18 simiarly embraced liy the ends 14 and 14 of the actuating spring, and the latter thus tends to keep both of said lugs 11 and 18 in the same place. The rock lever and contact piece would consequently move together were no detent provided to temporarily restrain the latter.
The snap make and break for the contact piece is secured in the present case by means of dogs 19 pivoted on the standard B at the 12, and being below the pivoting point, the
impact of the lug 11 against the same throws the claw 1) down into position to engage the 1 lug. The action of the dogs is thus automatic. To disengage the same, lugs 20 struck up from the rock lever, l, engage the shanks c of the dogs at the end of the downward stroke of the out push button, rotating the claw b and thus freeing the lug 11 and permitting it to snap across the slot 12 to the opposite end where it is engaged by the other dog as described.
This construction may be variously modified without departing from my invention.
7 I claim as my invention:
1. In a push button switch, an oscillating contact piece provided with a lug, a rock lever actuated by the push buttons and spring means for actuating said contact piece upon the actuation of said rock lever, in combination with dctents to engage said'lug on the contact piece, and adapted to be actuated by the impact of the latter and means in connection with the rock lever for disengaging said detents.
-2. In a push button switch, a standard carrying the switch mechanism, and provided with a guide slot, a lug on the contact piece working in said slot, dogs arranged at each end of said guide slot to engage said lug and adapted to be moved into engagement with said lug by theimpact of the latter against the same, substantially as described.
3. In a push button switch, a standard carrying the switch mechanism, and provided with a guide slot, a lug on the contact piece working in said slot, dogs arranged at each end of said guide slot to engage said lug and adapted to be moved-into engagement with said lug by the impact of the lattrr against the same, together with a rock lever to actuate said contact piece and means in connection therewith to move said dogs out of engagement with said lugs, substantially as described,
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
