l eoiaims. (C1. 20o-5o) For a detailed description of the present form of our invention, reference may be had to the following specification and to the accompanying drawings forming a part thereof, wherein Fig. 1 is a side elevation of our device;

Fig. 2 is a plan of Fig. 1; Fig. 3 is a longitudinal section of Fig. 1; Fig. 4 is a plan of Fig. 3 with the lid up. Our invention consists in a panel switch having certain novel features that will be described herein in detail.

Our switch consists fundamentally of a toggle together with an operating handle l that throws the toggle to one side or the other of the dead center and is itself positively set thereby in either open or closed position.

The toggle is composed of two bars, 2, 2, anda rod 3 that is surrounded by a compression spring 4. The bars and rod aforesaid are both joined to a roller 19 which makes contact below with an anvil pin and above with an anvil cross* rod 13. The bars 2, 2 are pivotedat their rear ends to a standard 21 and the rod 3 is free to slide with respect to roller 19.

'2'5 The handle l is composed of a thin arc-shaped plate of insulation having at top a short trans.

verse bar 5. At the bottom of the handle there are riveted cheek plates 27 which extend forward to form the pivotal point of the aforesaid rod 3. The said rod 3 terminates at its rear end on a block 22 which is forked to embrace the pivotal crossrod joining the aforesaid cheek plates 27. The pressure of the spring 4, which surrounds rod 3, acts against the said block 22 to hold it in engagement with the cross-rod. The upper end of handle 1 carrying the cross-bar 5 projects upwardly through the hinged lid 16 that covers the switch. In this lid 16 is a slot 40 (Fig. 2) which receives the blade portion of the handle. This 40 ,slot is enlarged, as indicated at 5, so that the cross-bar 5 stands across the slot and above it,

when the switch is clod, as it is in Figs. 1 and 2,

but when the switch is open, as itis in Figs. 3. and

4, bar 5 comes opposite the enlargement 5, and the lid can then be lifted, the cross-bar 5 passing through the opening 5a in the lid. 'I'he standard 21 is provided with an extension having means for connection with an electric conductor, as shown. On the under side of lid 16 is an angle piece 17 (see Figs. 1 and 3) which passes through an opening in latch 18 when that latch stands upright. But when the switch is open, as in Fig. 3, the handle 1 engages the said latch 18 and tips it over to the left, as shown in Fig. 3, against the force of its spring 30, which is overcome by spring 4, and thereby releases the said angle 17 and the cover 16 to which the angle is secured. 'Thereby the lid or cover 16 can not be lifted when the switch is closed, being locked by 18 and 17. The switch must be opened, as shown in Fig. 3, be- 69 fore the lid 16 can be lifted. Moreover, there is xed to the under side of lid 16 an arc-shaped piece of insulation 32, which, when lid 16 is lifted, stands at the right of handle 1, as shown in dotted lines in Fig. 3, and prevents the closure of the switch, so long as the lid 16 is lifted. At the left of the switch in Fig. 1, is a fuse 33 seated on the insulating base 9, and at the left of the fuse is an upright insulating wall 34 on top of which the lid 16 rests when it is down. At the 'i0 right of the switch is a chute 12 of insulating material which surrounds the conductor rod 13 having a suitable binding post, so that it may be connected with an electric conductor. The toggle aforesaid projects into the lower part of said Ft chute 12 and roll 19 makes Contact therein with the rod 13 when the switch is closed and with pin 25 when it is open. On the iiat sides of chute 12 and outside of it are magnetic plates 11 which form the poles of the magnet 10 and serve to ex- 80 tinguish any arc at the switch contacts.

Inoperation the switch handle snaps hard over the dead center of its toggle. In closing the toggle, bars 2, 2 and rod 3 spring up against cross-bar` 13, while in opening they spring down against pin 25. The turning of handle 1 swings the forked block 22 up or down in an arc having the pivot 6 as its center.v This compresses the spring 4 and then allows it to re-expand as it goes over the dead center to force the roll 19, on the right hand of the bars 2, 2, either up against cross-bar 13, or down against pin 25. The handle 1 can not close the switch while the lid 16 is up, nor can the lid 16 be lifted until the switch is closed. Only while the lid is down and locked can the switch handle be worked freely to close and open the switch.

What we claim as new and desire to secure by Letters Patent is:

1. A toggle switch comprising a fixed support 10o having means for connection with an electric conductor, a handle pivoted to said support, a toggle member pivoted at one end to said support and having its other end free, a rotatively mounted contact member carried by said free end, a second toggle member having one end pivotally engaging said handle and its -other end slidably engaging said contact member, a spring acting upon the second toggle member, and oppositely disposed relatively spaced anvil pieces lying in the path of movement of said contact member in either direction and so positioned as to limit said movement in both directions, one of said anvil pieces being adapted to be connected with an electric conductor.

2. A toggle vswitch comprising a xed support,VV

` edge portion of said switch member during movehaving means for connection with-an electric conductor, a handle pivoted to said support, a toggle member pivoted at one end to said support and free at its other end, a rotatively mounted contact member carried by said free end, a second toggle member having one end pivotally engaging said handle and the other end slidably engaging said contact member, a spring acting upon said toggle member, a fixed anvil,

and a transversely disposed rod-like anvil located above said xed anvil, said anvils being so positioned as to limit movement of the toggle members in both directions, one of said anvil pieces being adapted to be connected with an electric conductor.

3. A toggle switch comprising a fixed support having means for connection with an electric conductor, a handle pivoted to said support and having a projectioma toggle memberpivoted at one end-to said fixed support and having its other Y end free, a rotatively mounted contact member carried by said free end, a toggle member having one end slidably engaging said contact member and the other end provided with a notched block engaging the said projection, a spring acting upon the second toggle member, and oppositely disposed relatively spaced anvil pieces, one of which is in the form of a transversely disposed rod, said anvil pieces being so positioned and arranged as to limit movement of the free end of the first mentioned toggle member in either direction, one of said anvil pieces being adapted to be connected with anh electric conductor.

4. In a toggle switch, a casing having a movable cover, a at switch operating member pivoted within said casing and extended through said movable cover, a spring latch connected and arranged to engage said cover, said latch being so positioned as to be engaged and displaced by an ment thereof in one direction, and a toggle memberpivoted to said handle, said toggle member having a spring capable of overpowering the springpressure upon said latch.

5. In a toggle switch, a casing having a. movable cover provided with a lug, a at switch operating member pivoted within the casing and eX- tended through said cover, said switch handle having a projecting portion, a latch constructed and arranged to engage said cover, said latch being so positioned as to be engaged and displaced by an edge of the projecting portion of said operating member during movement thereof in one direction, means applying spring pressure upon said latch normally'tending to move it-to locked position in engagement with said lug. and a toggle member pivotally connected with said handle and having a spring capable of overpowering the rst mentioned spring so that said latch will be held in said disengaged position.

6. In a switch, a casing, a perforated cover therefor having a slot therein, a flat pivotally mounted switch operating member extended through said slot While the cover is in closed position, said operating member having a transversely disposed handle, said slot-having a portion providing clearance for said handle, and a stop member carried by the cover in such position that the handle lies across the path of movement of said stop member while the cover is open.
