The present invention combetweentheindividual panels, and the back prises an. elongated or substantially rectanboard whereby circuit connections to each gular shaped receptacle 1, provided with a panel maybe broken temporarily, while the hinged lid 2, at its open top side, and being provided further, with suitable means 3, whereby the cover or lid, may be locked in closed position, when the operative parts contained within the receptacle are in proper order.

Each end of the receptacle is provided with a plurality of bushings, l, of insulating material, and thru which the various conductors to the mechanism within the receptacle, may extend. Also, suitable fuses 6, may obviously be interposed in the circuit in accordance to these needs.

Secured vertically and at each end of the back wall of the receptacle, is a guide 7, eac of these guides being provided with a pair of guideways. A back board 8 is mounted for vertical movabilitv within the receptacle by having its ends disposed within the innermost guideways of the guides 7. This backboard is adapted to rest upon its lower longitudinal edge in the manner shown in Fig. 3, and is o1 a width sufilcient to substantially abut the lid 2 at its upper edge to prevent any vertical movement thereof.

Two spaced pairs 01' guioe plates 9 E), are secured in vertical position on the back board, in the manner clearly shown in 1. Each of pair of guide plates are disposed with their single guidewa s facing in opposite di rection, so that the outermost guide plates of each pair will have its guideway in opposed spaced relation to the guide '5, while the innermost guide plates will have their guideways also in spaced opposed relation.

A. slide panel 10 mounted vertically slidable between the guideways in the manner shown in F i g. 1. An angle bar 11 is secured to the back board below each panel to support the same, spacedly above the bottom of the receptacle.

As is perspectively shown in Fig. 10 of the drawing, an L-shaped member 1 is secured below each panel 10 and to the back board. Upon the horizontally disposed portion of each member 12, is a tl-shaped member 13, secured at its bight portion. The bight portion of these lei-shaped members are provided with a laterally disposed lug 14 to which the main feed line is connected.

A bar 15 is horizontally disposed and connected to the back board 8 above the upper end of each panel. This bar is prei craoly of an insulating material, while one end th ereoif is pivotally secured between the free ends of an il -shaped support- 16, which is secured at its bight, to the back board above the space between the panels.

Each of these bars 15, is provided with. a pair of clamped bands 1717, to which the usual timing wires are connected. Each bar is further provided with an additional clamped band 17, having connection with the usual load wire of the signal system.

Each panel is provided with a pair o plates 19-19, which project above the top edge of the panel and to which is secured a spring clip 20, adapted to contact with the bands 19 of the bar 15, to maintain a circuit to the conventional electromagnetic device A, from the timing mechanism, through the conductors 18.

[in additional upstanding plate 21 is likewise provided with a similar clip for con-- tact with the ban d 17, oi" the bar 15, for maintaining a surface connection of the usual load wire througl'i the conductor 22, to the conventional circuit maker and breaker B The "feed side of the circuit maker and breaker has connection to a depending conductor plate 23, which engages between the upstanding spring legs of the lJ-shaped stationary contact 13.

In the operation of the conventional mechanism, designated by A and B respectively the working parts are mounted in the manner disclosed in Fig. 1, and during the operation of this type of mechanism, frequently repairs or replacements are necessary. Heretofore in order to perform the same, it was necessary to disconnect the particular lamp circuit control impaired.

By mounting the circuit controlling mechanism to each signal light, on a separate panel, and supporting this panel removably on the removable back board, of this invention, when the pivotal bar 1:3 is swung outwardly from the back board, so as to disconnect the clamped band from the clips carried by the back board, or panels, the panel with which the said moved bar is associated, may be lifted vertically from the receptacle.

this panel may need repair, requiring considerable time, another panel carrying the same mechanism may he slid within the guideways, for operative disposition in lieu of the impaired panel. It will be seen that when the panel needing repair is lifted Vertically, the conductor plate 23, breaks the con tact with the current feed contact 13, whereas the timing connections have been primarily broken by the movement of the bar 15.

llllltllGIIilOIG, the receptacle is preferably filled to a level above the contact points oi the conventional circuit maker and breaker B, with oil, designated by numeral 24:. B this provision, the various movable parts of the mechanism will be thoroughly lubricated, thus requiring little attention, and alsoserving materially to lessen the noise resulting from the operation thereof.

Having thus described my invention, what 1 claim as new is 1. In demountable supporting means for multiple circuit controllers, wherein each circuit is controlled by an independent circuit making and breaking mechanism, a plurality oi demountable panels each supporting an independent circuit actuating mechanism, switch means carried by the said panels for connecting the mechanisms thereon to the associated conductors, means for securing said panels against displacement, said means consisting of a base board upon which are arranged pairs of spaced guides in which the panels are slidable, and elements carried by said base board for fixing the positon of the said panels.

2. In demountable supporting means for multiple circuit controllers, wherein each circuit is controlled by an independent circuit making and breaking mechanism, a plurality of demountable panels, each supporting an independent circuit actuating mechanism, a base board upon which the panels are mounted, and switch means between said panels and the base board for connecting the independent circuit actuating mechanisms to conductors associated therewith.

3. In demountable supporting means for multiple circuit controllers, wherein each circuit is controlled by an independent circuit making and breaking mechanism, a plurality of demountable panels, each supporting an independent circuit actuating mechanism, a base board upon which the panels are mounted, and switch means between said panels and the base board for connecting the independent circuit actuating mechanisms to conductors associated therewith, said switch means including a bar of conductive material pivotally connected at one end to the base board adjacent each panel, and complementary contact means between the bars and the circuit actuating mechanism thereon.

In testimony whereof I affix my signature.

WILHELM CARLSON.
