INTERCHANGEABLE HOOD-SUPPORT FOR HlGH-TENSION-ELECTRiC-LAMP SERVICE.

SPECIFICATION formingpart of Letters Patent No. 712,652. dated November 4, 1902. Application fi ed January 24, 1902, b'erial No. 91,016. (No model.)

To all whom it may concern:

Be it known that we, JOHN H. B. CQNGER and CHARLES J. EIOHHORN, citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Interchangeable Hood-Supports for High-Tension-Electric-Lamp Service; and We do hereby declare the following to be a full,

I0 clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same,

reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The objects of this invention are to provide a more durable, convenient, and effective insulated connection for high-tension electric street lamps and hoods, to guard more perfectly against leakage or loss of electric fluid or power, and to secure other advantages and results, some of which may be referred to hereinafterin connection with the description of the working parts.

The invention consists in the improved electrically-insulated hood for street-lamps, in the insulated connections therefor, and in the arrangements and combinations of parts of the same, all substantially as will-be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corre- 3 5 sponding parts in each of the several figures, Figure 1 is a side elevation of our improved device. Fig. 2 is a similar view showing a modification of construction. Fig. 3 is a vertical sectional View, and Fig. 4 is a plan of a 0 frame from which the hood and appliances are suspended.

In said drawings, a indicates an electric lamp of any usual form of construction. I) is a hood or reflector therefor; c, a tubular connection upon which said hood is immediately suspended and through which the electric wires (1 may pass to the lamp, the said tubular connection being threaded at its upper end to receive a hood-like casting 6, adapted to protect the passages f to the tube from water or the like. Said casting c has arms g,

on which glass, porcelain, or other supports may be secured to receive and hold the electric conducting-wires, as indicated, or other wise. In the construction sometimes pre' 5; f erred the upper end of said casting is screwed or otherwise seated in or to the bottom of a block of insulation h, (shown in Figs. 1 and 2,) and at the top of said insulation is inserted a bar or support 2', the casting hand support 1' being insulated from one another by interior parts or portions of said block. The support 1' in Fig. 3 extends directly from the casting e, the insulating-block h being in this case dispensed with. The upper end of the connecting-support i is screw-threaded and enters a corresponding threaded recess or socket j in a glass insulating cap it. Said cap is peripherally grooved, as

at Z, and is thus adapted to receive the sec- 70 tional collar m. The sections of said collar fitloosely within the groove Z and are riveted or bolted together, as at m, at their ends, so that said collar is held in place in the capgroove and yet permitted a free rotary or oscillating movement on said cap. Between the connected ends and at opposite sides of the collar the latter is provided with upwardlyextending arms '21, preferably fastened to the sections by means of screws "0, so as to be iu- 8o terchangeable with other arms of greater length, said arms at being provided at thetop each with trunnions or a cross-head n adapted toengage the oppositely-extending hooks p of a footpiece q, attached to a suspensory rod or tube 1', fastened or attached to any suitable fixture. The said footpiece is preferably detachable from the said rod or tube r, and the hooks are preferably in pairs to engage the oppositely-extending arms of the 0 said footpiece.

The construction thus shown permits a free pivotal turning of the hood, lamp, and means for holding the conducting-wires, as will be evident, and the double insulation effects a greater security against a short-circuiting or grounding of the current.

Having thus described the invention, what we claim as new is- 1. The combination with the lamp, hood- I00 and supports for the wire, of the tubular connection c, casting f, adapted to protect the passage through said connection 0, from moisture, a grooved insulation connected to said casting, a collar loosely arranged in the groove of said insulation, a footpiece having opposite hooks and connecting-arms attached to the collar and each having a cross-head held by said hooks and a support for the said footpiece, substantially as set forth.

2. The combination with the support 1, of a footpiece, arms and collar, forming a frame, a grooved insulation arranged in said frame and movable pivotally therein, and an electric lamp supported by said insulation, substantially as set forth.

3. The combination with the support 7", of a fo'otpiece having hooks at opposite sides, arms having trunnionsarrangedin said hooks, said arms extending downward from said hooks to a collar to which said arms are connected, an insulation arranged in said collar and a lamp in turn carried by said insulation, substantially as set forth.

4. The combination with the support, hood and lamp, of the interiorly-threaded insulation pivotally secured to said support, a supporting-bar z, screwed axially into said insulation, a second insulation 72, secured to said bar 2', and suspensory connections with the said hood and lamp supported from said insulation h, substantially as set forth.

5. The combination with a support, of a frame attached to said support, the lower part of said frame having a collar lying in a hori zontal plane, or a plane perpendicular to the said support, agrooved insulation arranged in said frame, and adapted to move on a vertical axis in said frame, the said insulation being recessed in said axis and threaded and having suspensory means screwed therein and a lamp and hood secured to said suspensory means, substantially as set forth.

In testimony that we claim the foregoing We have hereunto set our hands this 6th day of January, 1902.
