ELECTRICAL FITTING.
Specification of Letters Patent.
Patented July 6, 1915.
Application led November 25, 1912. Serial No. 733,519.
To all whom it may concern Beit known that I, RANsoM lV. Divianroirr, a citizen of the United States of America, residing at Detroit, in the county of `Wayne and State of Michigamhave invented certain new and useful Improvements in Electrical Fittings, of which the following. is a specification, reference being had therein tothe accompanying drawings. y The invention relates to, electrical fittings and is more particularly designed for use in connection with electrical 'heaters and other electrical instruments.
It is the primary object of the invention to provide in a single compact fitting a controlling switch and a socket connector for the detachable coupling of the heater or other instrument; further, to combine in said fitting a fuse-holder; and further, to so design and constructk the fitting that it may be easily mounted upon the stove or other device to which it is applied, and compactly arranged and associated with similar' fittings -for controlling other circuits.
With these objects in view the invention consists in the. construction as hereinafter set forth.
In the drawings: Figure 1 is a sectional end elevation of the fitting; Fig. ^2 is a perspective view of the Vinsulator body or block detached; Fig.3 is a front elevation of a stove, showing 'aseries of fittings applied thereto and the manner of mounting the same thereon; Fig. 4 is a front elevation of Fig. 2; Fig. 5 is a perspective view, showing the rear side of the fitting. Fig. G is a diagram showing the arrangement of circuits.
In the construction of electric stoves, it is usual vto provide a plurality of electrical heating units for different purposes, such as baking oven, broiler, surface heater, etc., and which are separately controlled. Each of these units should be controlled by an independent fuse anda switch, and for per- Initting removal or exchange of the unit there should be provided a detachable connector. With niy improved construction a single fitting is adapted to form these sevy eral functions, the construction being as follows: A is a body or block of insulating;
material, such for instance as porcelain; B is a control switch mounted upon the block A; and C are fuseholders also formed in the block. To permit of employing a standard construction of switch, the block A is provided with a seat D for the usual round switch base, and beneath this seat is a re-4 cess E forreceiving the connectors F leading to the fuse-holders or sockets C.
For convenience in mounting, the block A is'preferably of rectangular form and is provided on opposite parallel edges with grooves Gr, which are adapted to slidably engage rods or bars H on the mounting. As
`shown in F ig. 8, a series of fittings are mounted adjacent to each other at the front of the electric stove, the front rail I of vwhich forms the upper guide bar, while a Iower-bar H is supported by brackets J at opposite ends thereof, depending from and secured to said rail I. The service conductors K extend longitudinally of the entire series and are arranged in grooves L in the rear side and adiacent to the opposite edges of the block. Connection to these conductors is made through clamping contacts M arranged in recesses N in the block and scoured by a screw O, forming one of the contacts for the fuse socket C. The same screw clamps the annular contact I for said socket to the connector F leading to the switch B.
Connection to the heating units or'other velectrical instrument to be controlled is formed by a detachable plug-connector, which engages socket contacts in the block A through entrance apertures in the rcar face thereof. As shown, Q, is the ping-con-I nector', which may be merely an insulated 90 tends into the aperture R. Two of these contacts are clamped to the connectors F by suitable -nuts F engaging the threaded eX terior of the rods. The recess portion is also preferably split to form a yieldable, resilient socket. end of the connectors Q into the aperture R it will be .electrically connected with the rod T and through the latter with the switch contacts. r
In Fig. 6 is illustrated a Specic applica- 110 The socket contact is 95 Thus by merely inserting the tion of the fitting tc a heater circuit, in which the switch contacts S and S are connected by the connectors F and uses C respectively to the leads or service conductors K. The heating resistor V is provided with three conductors V V2 and V, leading-from the opposite ends of the resistor andv from an intermediate point, and the ends of these conductors may be respectively engaged with the contact members S2 S and S3. Thi will permit of developing either low or high heat by manipulation of the switch, so as to bridge alternatively between the contacts S S and S2 S, while in intermedia-te position the circuit will be open.
When it is desired to develop high heat, the contacting members S S2 are'bridged, causing the current to pass throughthe conductor V and the resistor V, the current then passing on'through the carrienF and the fuse block adjacent thereto. When low heat is used the contactsS S3 are bridged,
the current passi-ng through one half' of the resistor and leading out through the conductor F. The contacts S S are bridged when the heating resistorl is not in use, the current then passing through the conductor F, without entering the resistor.
As shown in Fig. 3, a series of the'fittings` may he arranged adjacent to each other and connected to the same lea-ds or service conductors, while all of the circuits controlled by said fittings may be conveniently and detachably connected therewith. All of the live contacts are completely concealed and protected. by insulation, and at the same time the fittings are readily mounted or detached by merely clamping or unclamping the contacts M and removing the block from the` supporting rails H and l.
It desired a plate of insulating material may be arranged to cover the backs of the fittings, in which case naked service wires maybe employed.
What l. claim as my invention is:
l. An electricallitting comprising an insulator block, there being grooves arranged in the block whereby the same may. be engaged by' a mounting, said block having con nectcd sockets in one of its faces, a switch 'in one of said sockets, a fuse arranged in an adjacent socket, an electrical connector be tween said switch and fuse, and a plug receiving socket contact connected to a switcln contact opening through the opposite face of the block.
2. An electrical fitting comprising an insulator block, recessedin one faceto form connected sockets, a switch in one of said sockets, a fuse in another of said sockets, an electrical connector between said switch and lfuse, and a plug-receiving socket contact conductor in the groove on the rear a'ce of said block, and a plug-receiving socket con- 1 tact connected to a switch contact and extending into an aperture in the rear face of said block.
4. An electrical fitting comprising a rectangular block grooved upon opposite edges for engagement with a mounting, recessed on its front face, longitudinally grooved upon its rear face for the reception of service conductors, and apertured through the rear face, a switch mounted 1n the recess 1n said front face, a plug-receiving contact in the aperture in said rear face and connected to one of the switch contacts, a fuse-holder also in said front recess, and a connector between said fuse socket and the conductor` in said rear groove. ln testimony whereof aihx myl signature in presence ci two witnesses.
