SWITCH-OPERATING MECHANISM.

Application filed December 1923. Serial No. 678,351.

This invention relates to switches and has for its object a particularly simple and eflicient operating mechanism for switches lo cated in boxes, which mechanism is movable parallel to the plane of the cover or the open side of the box and is detachable upon removal ofthe cover and attachable upon the placing of the cover on the box.

The invention consists in the novel fea- 1 tures arid in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a longitudinal, sectional view I partly in elevation of a switch and box provided with this operating, means.

Figure 2 is a fragmentary plan View of the box.

Figure 3 is a fragmentary detail view of the switch.

1 designates a box which may be of any suitable form, size and construction, the box being open at one side and having means as internally threaded nipples 2 for connection to conduits which enclose the service wires.

3 is a cover for theopen side of the box, the cover being detachably secured in any suitable manner as by screws 1 extending through the margin of the cover and threading into the lugs 5 in the box near the open side thereof.

6 designates the .switch, as a whole, the switch being mounted on a base of insulation 7 suitably mounted in the box on the side thereof opposite the cover. This switch may be of any suitable form, size and construction and the construction thereof forms no part of this invention.

Generally the switch includes a movable switch arm 8 pivoted at 9 between its ends to a frame 10 mounted on the insulating base 7, the ends of the arms being movable'into and. out of engagement with contacts 11, 12 mounted on the base and connected to service wires. The arm 8 is actuated to have a snap or' quick make and break action by an actuating part 13 extending toward the open side of the box or the cover 3, this part 13 being here shown as a lever pivoted. at 14 to the frame 10 and having anarm 15 connected to a carrier or rod 16 for a spring 17 arranged to shift from either side to the other of the axis 9 of the switch arm 8 in order that the spring may rock the switch after the part or lever 13 has been actuated far enough to shift the spring 17 to such position that the direction of its force on the yoke 18, which throws the switch arm 8, is reversed.

As the construction and operation of various forms of quick break switches are well known, further description is thought to be unnecessary and the switch mechanism, in so far as this invention. is concerned, is pertinent only in, so far as it includes an operatmg part extending toward the cover.

The operating mechanism for said lever or part 13 comprises a rod or slide 19 movable in the cover and connected to the arm 13, the rod or slide 19 being movable in a direction parallel to the plane of the open side of the box or cover. Preferably the cover is formed with a dome portion 21 and the rod or slide 19 extends through a guide opening in a side wall 22 of the dome portion, and has a handle or knob 23 at its outer end and means at its inner. end for engaging the actuating part or lever 13. The rod, as here illustrated, has a fork 24, which receives the end of the lever 13. The handle or knob 23 moves over the outer face of the cover within the limits or outline of the cover.

Owing to the fork, the operating part disengages from the part 13, when the cover 3 is removed, and also engages said part when the cover 3 is placed on the box. The rod 13 is also shown as formed witha head 25, which engages the inner faces of the walls of the dome 21 and holds the rod from turning, the fork 24 before referred to is here shown as carried by this head 25. The knob or handle 23 moves over the cover on the outside of the dome portion 21 and hence does not project beyond the outlines of the g5 ox or cover, so that, being arranged within the outlines of the box or cover and movable in a direction parallel to the plane of the cover, it is protected against unintentional operation.

What I claim is:

1. The combination with a box open at one side, and a switch located in the box'and having actuating part extending toward the open side, of a cover for the open side havm5 ing a dome-shaped portion and an operating member slidable .through a side wall of the dome-shaped portion in a direction parallel to the plane of the open side of the box and being connected to the actuating part, the" 110 operating member having a head movable between the inner faces of the side walls of the dome-shaped portion. I 2. The combination with a box open at one 5 side, and a switch located in the box and having an actuating part extending toward the open side, of a cover for the open side having a dome-shaped portion, and an operating member slidable through the side wall 10 of the dome-shaped portioh in a direction parallel to the plane of the open side of the box and being connected to the actuating part, the operating member having a head movable between the inner .faces of the side walls of the dome-shaped portion, and also 15 having a fork receiving said actuating part.

In testimony whereof. I have hereunto signed my name, at Syracuse, in the county of Onondaga, and State of New York, this 15th day of November, 1923.
