JOSEPH KINTZ, OE BALLARD VALE, MASSACHUSETTS, ASSIGN OR OF ONE- HALF TO THE ORAIGHEAD d: KINTZ COMPANY, OF NEYV YORK, N. Y.
ELECTRIC-LIG HT FIXTURE.
SPECIFICATION forming part of Letters Patent No. 47,832, dated March 10, 1891;
Application filed May 15, 1890- Serial No. 351,868. (No model.)
To all whom it may concern.-
Be it known that I, JOSEPH KINTZ, of Ballard Vale, in the county of Essex and State of Massachusetts, have invented a certain new and useful Improvement in Electric-Light Fixtures, of which the following is a specification.
I will describe a fixture embodying my improvement, and then point out the novel features in the claims.
In the accompanying drawings, Figure 1 is a central longitudinal section of an electric- .light fixture embodying my improvement.
Fig. 2 is an end view of the main part or upper section. Fig. 3 is an end View of an arm or secondary part. Fig. 4 is a bottom View of the two parts or sections detached.
Similar letters of reference designate corresponding parts in all the figures.
A designates the main part or upper section. It consists of a plate a, having a forwardly-extending hollow projection a and a nipple or socket a projecting from the latter. This part may be secured in any suitable manner to a wall or any other supportas, for instance, by screws passing through holes a in the plate a. The projection a is shown as of rectangular form and as cast integral with the plate a. The nipple or socket a maybe made separately and provided with a shank having an external screw-thread and fitting in and engaging a tapped hole in the forward part of the projection a. In the back of the nipple or socket a a block a, of wood or like material, is inserted. Preferably it will be driven tightly into place, or it may be secured in position in any desirable manner. A pin a extending longitudinally into the nipple or socket and block, acts as a key, preventing the rotation of the block independently of the nipple or socket.
a a designate two electrodes extending longitudinally through the block a As here shown, these electrodes consist of wires driven into the block side by side, and having at the rear end eyes, with which wires a a, forming part of an electric circuit,'are connected. At the front end these electrodes project slightly beyond the block.
13 designates an arm or secondary section of the electric fixture. It is made in the form of a tube constructed at one end to fit the nipple or socket a and provided at the other end with a nipple b, to which an electric lamp may be fastened. The end which enters the nipple or socket a is provided with a block b, of wood or like material. Preferably this will be driven into place. As shown, it has a notched flange-like portion projecting beyond the main portion of the part or section B. The part or section B has, however, alug 11 which extends into a notch in the flangelike portion of the block, interlocking therewith, so as to prevent any rotary movement of the block. Electrodes b b are inserted in the block b in positions corresponding to the electrodes a a They maybe made like the electrodes to a and inserted to project slightly beyond the protruding end of the block. WVires a (0 may be engaged with them and extended through the part B to its nipple b for connection with a lamp.
Around the part B, near the end which engages with the socket, is a circumferential rib b which maybe formed upon or attached to the part in any suitable manner. When the end ofthe part B is inserted in the nipple or socket, this rib will be close to the outer extremity of the nipple or socket. The electrodes b b will then bear against the electrodes a Q The part B is also provided with a longitudinal rib b. 'This will project into a notch a with which the nipple or socket is provided, and will thereby preclude any rotary movement of the part B relatively to the part A.
C designates a coupling-piece, consisting of a ring surrounding the part B forward of its rib b and having an internally-screwthreaded flange which will extend over the said rib and engage with the externally-screwthreaded forward outer end of the nipple or socket 19 When the two parts AandB are fitted together, the rib b will interlock with the notcha and insure a proper meeting of the two pairs of electrodes, and the coupling-piece will maintain an efficient contact between them. The projection of the electrodes 19 b willbe such that when the coupling-piece is engaged these electrodes will be forced into contact with the electrodes at a before the circumferential rib b on the part B will reach the opposite end of the nipple or socket a and also before the extremity of the longitudinal rib b can reach the bottom or inner end or the notch a in the nipple or couplingpiece.
By my improvement I produce a very simple electric fixture which may readilyhave its sections separated and reunited in proper relation.
WVhat I claim as my invention, and desire to secure by Letters Patent, is
. 1. In an electric fixture, the combination of a main part or section provided with a nipple, a plug inserted in the back part of the nipple, electrodes fitted in said plug and protruding from the forward end of the plug, a secondary part or section made in the form of a tube, a plug fitting in the inner end of said secondary part and having a flange-like portion lapping over said end of the secondary part and a notch in said flange, a rib or tongue on the secondary part entering the notch of the flange, electrodes in the last said plug, and a coupling-piece connected with the one part and engaging with the other, substantially as specified.
. 2. In an electric fixture, the combination of a main part or section composed of a platelike portion having a hollow forward or out Ward projection and a nipple inserted in said projection andconstructed so as to be open at both ends, a plug inserted at the back end of said nipple, electrodes arranged in said plug, a secondary part or section made in the form of a tube of a size to enter the outer end of the nipple, a plug in said secondary section, electrodes in said plug, and a couplingpiece connected with the one part and engag ing With the other, substantially as specified. 4o
