JOHN JAY GREEN, OF BOONTON, ASSIGNOR TO THE SECURITY INSULATOR COMPANY, OF ELIZABETH, NEW JERSEY.
CEILING-BLOCK.
SPECIFICATION forming part of Letters Patent No. 484,911, dated October 25, 1892. Application filed May 17, 1892. Serial No. 433,267. (No model.)
T @ZZ whom it may concern:
Be it known that I, JOHN JAY GREEN, a citizen of the United States, residing at Boon ton, in the county of Morris and State of New Jersey, have invented certain new and useful Improvements in Fuse- Blocks for Electric 1Iiires, of which the following is a specificaion.4
My invention relates to a device termed a 1o fuse-block, which is placed at the point of junction between the main wires of an electrical distributing circuit and the branch or consumption wires leading to a' translating device, such as an electric lamp or motor.
Such a f use-block consists, usually, of a closed case or box of incombustible material formed of a base-piece and a cover fitted thereto,
within which are placed two pairs of metallic terminals or clamps, one pair for the main 2o and the other pair for the branch Wires, these being respectively united by means of fusewires, the thicknesses of which are adjusted in such relation to the current intended to be carried to the translating device that in case of an excess of current they Willbe fused and will interrupt the circuit.
The object of my invention is to provide a fuse-block Which shall effectually exclude air or moisture from the terminals and connecgo tions of the wires at the points of junction inclosed therein, and which may therefore be used in chemical manufactories, salt-Works, and other like places in which the atmospheric and other conditions are destructive to the integrity of the wires and connections when inclosed in a f use-block of ordinary construction.
In, the accompanying drawings, Figure 1 is a transverse vertical section of a ceilingpendant fuse-block embodying my invention, taken in the plane of the dotted line 1 1 in Fig. 3. Fig. 2 is a cross-section of the same, taken in the plane of the line2 2 in Fig. l. Fig. 3 is an inverted plan of the base -With the cap removed; and Fig. Lt is a plan view of the cap, showing the arrangement'of the fuse connections attached to the same.
The particular form of the device which I have selected for illustration of myinvention is termed a ceiling fuse-block, being usually affixed to a ceiling in order to permit of the attachment, for example, of a pendent incandescent lamp. The incombustible base A, preferably of porcelain or glass, is secured to the ceiling` by wood-screws passing through 5 5 the countersunk holes a ct. It is preferably circular in form and contains a chamber B, surrounded by a flat circular bearing-surface d.
D is a cover, of the same material as the 6o base, and also preferably circular in form. This cover is provided With a similar flat bearing-surface d and is secured in position by ears CZ d, which interlock with grooved projections a2 a2, formed on the base A, as here- 65 inafter explained. Before putting the cover D in place a compressible and preferably elastic packing-as, for example, a ring of in dia-rubber-is placed between the opposite flat bearing-surfaces a and CZ', as shown at 7o C. The cover D is then put on by pressing it against the packing and laterally rotating it, so that the ears d d, which have beveled or inclined edges, as shown in Fig. 2, Will pass laterally into the grooves a3, and thus exert a compressive action upon the packing O, forming a tight jointimpervious to air, water, or steam and absolutely protecting the interior from the ingress of moisture in any form. Within this interior chamber B are 8o placed the metallic vterminals and connections F F of the electric conductors E E, which conduct the current from the main line to the branch. These terminals F F are secured to the base A by screws or otherwise and are 8 5 provided with spring-contactsff. The branch or consumption wires L L, which lead to the translating device, are attached to metallic terminals K K, secured to the inside of the cover D by screws or otherwise. The fuse- 9o terminals H H are L-shaped and their projecting portions h h enter behind the contactsprings ff when the cap is laterally rotated in the manner hereiubefore explained, in order to secure the cap to the base. The contact-springs ff after the cap has been thus rotated press against the f use-terminals H H by virtue of their inherent resiliency. As the fuses I I are clamped between the terminals H H and the terminals K K, it will be underroo stood that Whenthe eapDislaterally-rotated into position, so that its cars will interlock with the projections upon the base, the electrical connections will simultaneously be completed within the chamber B by the contact of the projections 7L h with the contactterial is applied to the apertures ee, through which the conductors E E are led into the4 chamber B of the base.
apertures for t-he admission of screws fonY fastening the terminals to theibase may also Thecountersnnky v 'with advantagebe sealed with paraine-Wax or other like material.
I claim as my invention- In a fuse-block for electric wires, the combination of the hollow base inclosing the terminals of the main Wires, the cap fitted thereto4 carrying the terminals of the consumptionwires, the compressible packing inserted be tween said base and cap, the interlocking Vprojections upon said base and cap for securing them together, and the interlocking terminals of the main and consumption wires, whereby the electric circuit is completed by the act of rotating the cap laterally into position to compress the packing, as set forth. In testimony whereof I have hereunto subscribed my namethis 2dy day of MayA. D.
JOHN' JAY GREEN.
