ELECTRIC SWITCH.

SPECIFICATION forming part Of Letters Patent N0. 635,691, dated October 24, 1899.

Application filed February 24, 1899. Serial No. 706,674. (No model.)

To ctZZ whom it may concern.-

Be it known that 1, CHARLES J. KLEIN, a citizen of the United States,'residing in the city of New York, borough of Manhattan, county and State of New York, have invented certain new and usefullmprovementsin Electric Switches, of which the followingis a speci fication.

My invention relates to electric switches adapted to effect a rapid closure or break of the electric circuit.

Iwill describe electric switches embodying my invention and then point out and claim the novel features of my invention.

In the accompanying drawings I have illustrated several forms of switch, each embodying the central idea of my invention, although I do not wish to confine myself to switches shown, as the details may be varied without departing from the spirit of my invention.

In the drawings, Figure 1 is a plan View of a hand-snap switch embodying myinvention. Fig. 2 is a side view thereof. Fig. 3 is a plan View of a single push-button switch embodying my invention, Fig. 4: being a sectional side elevation thereof on line 4 4 of Fig. 3. Fig. 5 is a sectional side elevation of a double push-button snap-switch embodying my invention. Fig. 6 is a bottom view of the switch shown in Fig. 5. Fig. 7 is a top view thereof. Fig. 8 is a sectional side elevation showing the contacts, and Fig. 9 is adetail of the shoe.

In the drawings similar letters of reference refer to similar parts in all the figures.

Referring for the present to Figs. 1 and 2, a is a porcelain insulation-base for the support of the contacts. I) are the contacts. 0 is the supporting frame or bar, having a bearing face or surface 0. d is a rocking lever, shown in the present instance as pivoted at d and provided with a bearing face or surface d The switching piece or bar 6 is preferably carried upon the end of a cross-bar f and preferably insulated therefrom. One of these switching-pieces is carried at each end of the cross-bar, although but a single piece can be so carried, if desired. Carried upon the cross-bar f is a shoe g, which carries the switching piece or pieces 6 and slides upon the bearing-face c of the upright or supporting-frame c. h is a grooved roller which bears upon the bearing-face d of the rocking lever 01 and is provided with an axle i, to which a spring or springs j are seen red, which spring or springs connect the roller-axle 7, with the cross-bar f.

The operation of the switch will be apparent from the drawings. Upon rocking the lever (1, let us say in the direction of the arrow, the bearing-surface (1 becomes inclined with respect to the bearing-surface 0, so that the tension of the spring or springs being exerted to pull the shoe and roller toward each other the said shoe and roller will be snapped downward, causing the contact-piece e to close the circuit between the contacts or springs Z) I). The parts will then be in the position shown in dotted lines. When it is desired to open the switch, the lever 01 is rocked in the opposite direction, thereby increasing the tension on the springsj and inclining the upper end of the bearing-surface d toward the bearing-surface c, whereupon the shoe and roller will rise, breaking the circuit.

It will be apparent that the underlying principle of my invention may be variously applied, and I have shown by way of example the principle applied to other forms of switches.

In Figs. 3 and 4 a single push-button is employed. In these figu res, k is a spring-restored push-button, which operates upon a rocking lever 01, acting upon a guide or supporting frame a in proximity to contact-springs b.

The supporting-frame c carries a sliding shoe or contact-piece g, which is connected by a spring j, whose end or moving piece moves on the rocking lever d.

In Figs. 5, 6, 7, and 8 a shoe 9 slides upon a supporting-frame c and carries a shaft f, provided with contacts e, placed in operative proximity to circuit-terminals or contact-- springs b. Pivot-ed to the frame a is a rocking lever 0, provided with a bearing-surface and stops 01 This rocking lever is operated by a pair of push-buttons 7t 7t and is provided with a roller 71, connected to the shoe g by means of springs j. The switches shown in Figs. 3, 4, 5, 6, and 7 operate in a similar manner to the switch shown in Figs. 1 and 2. The shaft f is insulated from the contactblocks 6 by insulation Z. The shoe has a projection Z entering between the side bars of the supporting-frame c, as clearly seen in.

ing the circuit between the terminals com-' prising a plurality of bearing-surfaces one capable of being inclined with respect to the other, a plurality of moving pieces each freely moving or sliding upon a bearing-surface and a spring connection between the moving pieces whereby an electric circuit may be opened or closed by inclining one of the bearing-surfaces with respect to the other, substantially as described and for the purposes set forth.

2. In a switch of the character described, the combination with circuit-terminals, of means for closing the circuit between the terminals comprising a fixed bearing-surface, a movable bearingsurfacaa plurality of springconnected pieces one bearing upon each of the bearing-surfaces whereby when the movable bearing-surface is inclined with respect to the other bearing-surface a movement of opening or closing the switch is effected.

In an electric switch, the combination with circuit-terminals, of means for closing the circuit between the terminals comprising the supporting frame or bar 0, the rocking lever cl and a plurality of moving pieces one moving freely upon the supporting frame or bar and the other moving freely upon the rocking lever, and a spring connection between the two moving pieces, whereby upon movement of the rocking lever the spring connection will be effective to open or close the switch. t.

4. In an electric switch, the combination with circuit-terminals, of means for closing the circuit between the terminals comprising a supporting-frame and rocking lever provided with bearing-surfaces capable of being made substantially parallel with or being inclined with respect to each other and a plurality of freely-moving pieces one cooperating with one bearing-surface and the other with the other bearing-surface and a spring connection connecting the said two moving pieces whereby when the bearing-surfaces are substantially parallel with each other the movable pieces will receive no motion and when the bearing-surfaces are inclined with respect to each other the moving pieces will be forced CHARLES J. KLEIN.
