CEILING FUSE-BLOCK.
SPECIFICATION forming part f Letters Patent NO. 434,925,dated August 26, 1890.
Application filed March l1, 1890. Serial No. 343,552. (No model.)
To all whom it may concern.-
Be it known that I, HORACE A. FITCH, of New Bedford, county of Bristol, and State of Massachusetts, have invented a certain new and useful Improvement in Electric-Lamp Fixtures, of which the following is a specification.
The obj ect is to provideabracket, cut-out, and base-piece so `constructed that the base may be permanently secured to a wall or ceiling with the main electric wires connected thereto, and whereby the cut-out and bracket may be removably secured to the base; and a further object in making the bracket detachable from the base is to provide a means whereby the connections may be easily reached, in order to make repairs to any of its'parts or affixing new fusible connections.
I will describe a fixture embodying my improvement, and point out the novel features in'the claims.
In the accompanying drawings, Figure 1 is a vertical section of a iixture embodying my improvement. Fig. 2 is a section of the same 'taken at right angles to Fig. l. Fig. 3 is a plan View of the base-block. Fig. 4 is a plan or interior view of the cut-out, and Fig. 5 is a longitudinal section through one of the ccntact-springs.
Similar letters of reference designate corresponding parts in all the figures.
Referring by letter to the drawings, A designates a base-block of insulating materialsuch as wood, hard rubber, or analogous substance-designed to be permanently secured to a wall or ceiling by means of screws a or otherwise. The base-block is recessed, as at a', in its front face to accommodate bindingscrews and connecting-plates.
a2 designates the two connecting-plates secured to the base-block within the recess, and main wires a3, passing through holes a4 in the base-block, are connected to the respective plates a2 by means of binding-screws a. The connecting-plates a2 also serve as a means for securing the cut-out to the base, as will hereinafter appear, and for this purpose I have provided them on one side with a notch or yoke a6. Recesses c7 in the base-block ex- 5o tend beneath the plates. These recesses are elongated so as to extend beyond the plate, and are made wider than the notch in the plates.
B designates a block of insulating material for the cut-out, having lugs o extended from it to engage with the plates a2 and secure the block B to the base. I have here shown the lugs b in the form of screws having a head b. lVhen it is desired to secure the block B to the base, the heads b of the lugs are placed in the recesses a7 above the plates, and then the block is pushed downward so that the Shanks of the lugs slide within the yokes and the heads underneath. The block B has a recess b2 correspondingto the recess a in the base-block, and within the recess are contactplates b3, each provided with two bindingscrews h4. Lamp-wires h5 lead from a binding-screw of each plate b3 through a central opening in the block B to a lamp. From the other binding-screws b4 wires h6 lead to binding-screws 117, connecting with resilient contact-pieces hs. The wires h6 are preferably of fusible metal, so that an excessive current will fuse them vand not damage the other parts of the cut-out. The contacts 118 are secured at one end to the block B by means of the binding-screws bl, and when in position the other ends of the contacts bear upon the plates a2 of the base-block, thus completing an electric circuit.` I prefer these contacts bs to be of quite stiff spring metal, so that they will serve the purpose of contacts and also by their pressure maintain a rigid connection between the block B and the baseblock.
C designates a portion of a bracket-arm to which an incandescent lamp may be attached. This arm has one end inserted in a socket in the block l5, which may be a metal bushing c, screw-threaded to receive the threaded end of the arm C. The opening through the arm C is in line with the central opening of the block B, so that the lampwires willbe unobstructed.
The base and block B may be ornamented in any desired manner and the block and bracket may be removed from one base-piece and placed upon another, so that one bracket may be employed in any part of a room or IOO building, thus saving the cost of several brackets.- It is evident, also, that a curved bracket-arm and block may be reversed or placed on the base, so that the lamp will be in a hanging or standing position.
By removing the block the fusible wires are easily accessible, so that they may be rencWed at any time.
Having described my invention, what I claim isl. The combination of a base adapted to be secured to a Wall or ceiling and having recesses, notched contact-plates secured to the base over the recesses and connecting with main Wires, a block having a central opening, resilient contacts on said block, lugs extending from the block engaging with the contact-plates on the base, the heads of4 said lugs passing into the recesses beneath the plates, and a tubular bracket-arm extending zo from the block, substantially as specified.
2. The combination of a base having the recesses c a7, notched contact-plates secured to the base over the recesses a7, a recessed block having a central opening, resilient contacts -on said block constructed to bear upon the contact-plates on the base, contact-plates b3 on said block, lugs extending from the block engaging with the contacts on the base, the heads of said lugs extending into the recesses a7, a threaded socket in the block, and a tubular bracket-arm engaging in said socket, substantially as specified.
