Joseph A. Messing, and
WillianiA. Harper, Detroit, Mich, assignors to Bulldog Electric Products Company, Detroit, Mich, a corporation of West Virginia Original application July 23, 1931, Serial No. 552,684, Divided and this application Anew! 19, 1933, Serial No. 685,972
6 Claims.
The inventions of this application relate to operating mechanisms for switches of the base and head type or of the block and receptacle type as they are sometimes known and this application is a division of our prior application Serial No. 552,684; filed July 23, 1931, now Patent No. 1,981,319, patented October 17, 1933.
The objects of the inventions of this applicae tionhave been distinctly set forth in the prior 10 application aforesaid and need not here be reviewed. It can be said however that it is the purpose of this application to cover a specific embodiment of operating-means shown herein and divided out from the prior application. This embodiment will readily be understood by those skilled in the art upon reference to the following description and the accompanying drawing in which Figs. '1, 2, and 3a, 3b, 3c are respectively, an elevational view, a compound view of the major op-v erating parts, and three-position diagrammatic views of an embodiment; ,r I
In this embodiment, there are receptacles 90, side plates 91, slots 95 and 95a, plugs 97, carriers :5 100, provided with pins 101 and 101a riding in slots 95, 95a and also pins 102 riding in the slots 103 of the members 104, pivoted at 105 and having handles 106.
When thehandle is first moved up pins 101 and 101a will ride vertically in slots 95 and 95a. Then, when the pin 101 has reached the end of the vertical part of slot 95,and when the pin 101a has reached the end of 95a, further movement of the handle will cause pin 101 to ride in the curved 3 path of the slot 95.
While handle 106 is shown as on pivoted member 104, it might well be on the carrier 100, in Y which case the device operates the same way,
though a mechanical advantage is lost. Further, 49 the pivoted members 104 may be dispensed with altogether, whereupon the upper end of sl'ot 95a should be provided with an enlarged part to hold pin 101a in place, and with it, the plugs. Further, slots 95 and 95a may be merged, if desired.
Now having described the embodiment disclosed, reference will be had to the following claims for a determination of the scope of the inventions of this application, and it is to be understood that the said invention is to be limited,
' not to the specific details herein set forth, but
only by thescope of the claims which follow:
What we claim is: 1. In a switch, a base, a head for cooperation therewith, and means for moving the head with respect to the base, said means including a side plate secured with respect to the base, and havplate securedwith respect to the base, and having a slot provided with a straight part and a curved part, and a second slot formed as a continuation of the straight part of the first slot, 9, carrier secured with respect to the head and having-spaced pins, one riding in each slot, and means pivotally mounted with respect to the side plate and piv otally connected to the carrier for moving the latter and causingit'and the head to move in a straight line path, and then in a curved path, in accordance with the formation of the slots.
2. In a switch, a base, a head for cooperation therewith, and means for moving the head with respect to .the base, said means including a side ing a slot provided with a straight part and a curved part, and a second slot formed as a continuation of the straight part of the first slot, a carrier secured with respect to the head and having spaced pins, one riding in each slot, and a handle secured with respect to said head for moving the head in a straight line path, and then in a curved path, in accordance with the formation of the slots.
3. In a switch, a base, a head for cooperation therewith, and means for moving the head with respect to the base, said means including a side plate secured with respect to the base, and having a slot provided with a straight part and a curved part, and a second slot formed as a continuation of the straight part of the first slot, a carrier secured with respect to the head and having spaced pins, one riding in each slot, and a handle for moving the head in a straight line path, and then'in a curved path, in accordance with the formation of the slots.
4. In a switch, a base, having a slot provided with a straight part and a curved part, and asecond slot formed as a continuation of the straight part of the first slot, and a head for cooperation with said base and provided with spaced pins,-one riding in each slot, for guiding said head to move first in a straight path and then in a curved path as it is withdrawn from said base. 100
5.111 a switch, a base, a head adapted to be moved towards and away from the base, and means for guiding the head as it ismoved with respect to the receptacle whereby the head moves in a straight line path perpendicular to the base as the head approaches or recedes from the base,
and, in' a diiierent part of its path of movement, moves in a curved path, the guiding means including spaced pins riding in stationary guide slots, one of which has a straight portion and a no in a curved path, the guiding means including spaced pins riding in stationary guide slots,
one of which has a straight portion and a curved portion, and the other of which has a straight portion formed as a continuation of the straight portion of the first mentioned slot.
