SPECIFICATION forming part of Letters Patent No. 597,979, dated January 25, 1898.

Application filed February 1., 1896. Serial No. 577,704. (No model.)

To ctZZ whom. it may concern:

Be it known that I, Jnssn L. limbs, of Syracuse, in the county of Onondaga, in the State of New York, have'invented new and useful Improvements in Electric Switches, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in electric switches particularly applicable for use upon a wall or switchboard, and has for its object the production of a device which is simple in construction, economical in manufacture, pleasing in appearance, and durable and eifective in use; and to this end it consists,essentially,in the combination, construction, and arrangement of a movable back or support, the terminal or blade carried by the back or support, and the means for securing the back or support to a base and holding the same in its adjusted position.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure l is a top plan of my improved switch. Figs. 2 and 3 are longitudinal, vertical, and horizontal sections taken, respectively, on lines 2 2, Fig. 1, and 3 3, Fig. 2. Figs. a and 5 are respectively an isometric view of one of the movable terminals or blades and an elevation of a collar for engaging said terminal or blade, and Figs. 6 and 7 are longitudinal vertical sections of slightly-modified forms of the means for securing the terminals or blades to the movable backs or supports.

A is the switch-base, which is of any desirable form, size, and construction and is preferably composed of insulating material.

B B are separated backs or supports arranged substantially parallel with the base A and having corresponding ends secured to a suitable cross-bar C and their opposite ends pivoted to supports or pillars D D.

E are movable terminals or blades detachably secured to the backs or supports B in any desirable manner, and F G are terminals fixed to the base A for making contact with the terminals or blades E. The wires leading to and from the switch may obviously be cured to sockets mounted on the shanks f of the terminals F, the shanks g of the terminals G as electrically connected by plates g to terminals g and the incoming wires h as secured to sockets mounted on the stems of terminals 9 which are connected by fuses g to the terminals 9 The backs or supports B preferably consist of slotted tubes, being formed with longitudinal internal chambers b and having their sides nearest the base A provided with longitudinal slots 1), opening into the chambers 19. Corresponding edges of the terminals or blades E are inserted through the slots 1) into the chambers 12 and are secured to the backs or supports B by engaging means, preferably arranged within the chambers b. This engaging means usually consists of opposite heads 5 b adjustable lengthwise within the chambers 17 and having their adjacent end faces provided with cylindrical centrally-arranged shoulders bfiadapted to enter cut-outs or notches e in the opposite end edges of the terminals or blades E and engage the shoulders formed by said cut-outs or notches.

B are detachable extremities for the backs or supports B, having their outer ends pivoted at B to the supports or pillars D and their opposite ends formed with sockets Z1 for receiving the adjacent ends of the main portions of the backs or supports B. These extremities B are secured in position by screwthreaded stems 5 provided upon the adjacent end faces of the heads 19 5 The opposite or free ends of the backs or supports B are encircled by collars ?2 and are suitably secured to the cross-bar O, which is arranged at an angle to the backs or supports B and is provided with a suitable handpiece 0'.

The backs or supports B and the cross-bar O are preferably secured together by screwthreaded stems 11 which are provided upon the heads 5 are passed through the collars b and the adjacent ends of the bar 0 and are engaged with nuts 17, arranged in recesses in the outer face of the bar 0. In order to prevent revoluble movement of the collars 73 upon the backs or supports 13, their end faces adjacent to the terminals or blades E are provided with shoulders 19 for engaging said terminals or blades, and their opposite end faces are formed With shoulders I) for engaging corresponding shoulders 0, provided upon the cross-bar O.

The supports or pillars D previously mentioned are preferably formed with internal longitudinal chambers 01 and lengthwise slots (1', extending from their outer ends to said chambers. Arranged within the outer ends of the chambers dare plungers D, having corresponding ends provided with shoulders (P, which are formed of less diameter than the plungers D and are engaged by cams B and stop-shoulders 13*, formed upon the attaching extremities ofthe backs or supports B. The cams B engage the end faces of the shoulders 61 and the stop-shoulders 13 engage the upright faces or peripheries of said shoulders d. The plungers D are preferably forced toward the pivots B of the backs or supports B by springs D interposed between the plungers D and securing-pieces D and having their opposite ends arranged in sockets in the adjacent faces of said plungers and securing-pieces. Corresponding extremities of the securing-pieces D are adjustable longitudinally within the chambers d of the supports or pillars'D, and their opposite extremities are suitably secured to the base A, being preferably provided with shoulders engaged with the rear face of said base.

It is obvious that the movable backs or supports of my improved switch may be provided with terminals or blades and securing means therefor different in construction from those seen at Figs. 1 to 5, inclusive, and at Figs. 6 and '7 I have shown modified forms of the securing means for the terminals or blades.

At Figs. 6 and 7 the backs or supports 13 B are provided with securing-heads I) Z9 12 6 having their adjacent end faces formed with inwardly-extending sockets for receivin g shoulders provided upon the terminals or blades E E The heads b I) are screwthreaded for effecting their longitudinal ad- 3' ustment within the back or support 13 and the heads N b are adjusted toward each other by a bolt Z2 The operation of my improved switch will now be readily understood upon reference to the foregoing description and the accompa nying drawings, and it will be particularly noted that the movable backs or supports and the terminals or blades may be economically formed by screw machinery and stampingdies and that these parts are readily assembled and afford contacting faces of considerable area.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
