1- 'rron on conunc'rrcnn' a a I s nner" To all whom it mag concern a; citizen of the United States of America,

and residing at Bridgeport, in the county of .Fairfiaeld and State of Connecticut, have invented a certain new and Improved Electric Gang-Fitting, of which the following is a,

' specification. H

1 My invention relates to electric gang fit.

the object of my invention isto provide a compact installation for a plurality of independent switch units.

' in the accompanying form; Fig. 2 is a plan thereof with the cover plate removed and one of the switches removed; and Fig, 3 is "a perspective of the carrying frame shown in Figs. 1 and 2.

The present. invention 18- particularly designedfor use in positions in which the available room for the installation. is limited this character.

and narrow, such for instance as the dressing room of. a, Pullman car. Only extremely narrow panels are here available for the switch gang installation which sometimes numbers as niany as eight switches in the.

gang. b'viously compactness and neat appearance are essential in an installation of independent removal-for repair orrene wal,

each switch since the vibration'of the car is apt to cause defects, and it is extremely simple and convenient, aswell as inexpensive, to handle unit separately in" case of trouble. I

fllhe switch gang here shown is carried on a suspension frame or bridge piece 10 having end flanges 11 with cars 12 to overlie the support 13 which may be the'inner wall of a metal car, cut away to-aflord a recess tov for the switch gang, and punched at Mto permit the passage of the screw jbolts 1L5 therethrough. llhe ears 12' may be West at llfl and tapped to receive the screws 17 of the faceplate 18'. e several switch units 19 parcel bodies of the switch.v are trape,

long axis of the trapezoid cut ofl' or flattened to permit the passa e to the terminals of the wires which are le thereto through marginal recesses or apertures in the base of the frame. Lateral support for the switch bases is afforded by flanges, such as- 24:, struck up from the frame base. Where these flanges are given the. form of continuous longitudinal side bars, they also impart addedr'igidity to the structure as a whole.

The switch spindles 25; pass up through the face plate 18 and receive the operating thumb pieces 26 threaded thereon. The switch mechanism, "per '86, is of commoncon struction. Y

The compactness of assembly of the independent switch units, the light supporting frame, the convenient wiring of the switch gterminals and the ready accessibility of the separate units for repair or replacement, which result from the novel construction specified, present advantages, the-novelty and value of which are readily recognized."

I claim as my invention V l. A gang fitting of. the type described, comprising a suspension frame havmg end pieces and lugs thereon for mounting the frame on a suitable support, in CODlblIlfltlOll with a plurality of independent electrical I I units having insulating bodies of like shape mounted on the base of said frame, wire terminals on each of said units and recesses at the'opposite margins of the base of the frame and adjacent each of said units for admitting leadingin wires to said term nals, together with marginal flanges on said base aflording lateral support for said units.

, 2. A gang fitting of the type descnbed,

comprising a 'suspension frame having endpieces and lugs thereon for mounting the frame on a suitable support, in combinatlon with a plurality of independent electrical units having insulating bodies of like shape mounted on the base of said frame, wire terminals on each of. said units and recesses at the opposite margins of the base of the frame and adjacent each of said units for admitting leading-in wires to said terminals, together with marginal flanges in the form of longitudinal strengthening bars affordinglateral support for said units.

3. h gang fitting of the \1 w M described, I c y a suspension he of generally trapezoidal shape in plan, end ieces there- 'on having lugs for mounting t e frame on a suitable support, in combination With a plurality of independent electrical units having insulating bodies of generally trapezoidal shape mounted side by side longitudinally of said frame, and relatively low marginal flanges struck up from the opposite sides of the frame base and engaging the units to afford lateral support thereto.

4. A gang fitting of the type described, comprising a suspension frame of generally tra ezoidal shape in plan, end pieces thereon aving lugs for mounting the frame on a suitable support, in combination with a plurality of independent electrical units having insulating bodies of generally trapezoidal shape mounted side by side longitudinally of said frame, together with a rectangular face plate overlying said fitting and secured to said supporting lugs, substantially as described. 7

5. A gang fitting of the type described, comprising a suspension frame having end uprights with lugs for mounting the frame on a suitable support, in combination with a plurality of independent electrical units having insulating bodies of generally trapezoidal shape with their corners flattened on the longer axis, juxtaposed on the base of said frame, Wire terminals on each of said fittings, and marginal recesses on opposite sides of the base of the frame to admit leading-in Wires, the space between said flattened corners and the side of the adjacent unit serving to form a Wire channel, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of tWo subscribing Witnesses.

GEORGE B. THOMAS.
