ARC-LAMP HANGER OR SUPPORT Specification of Letters Patent.

T0 all whom, it may concern:

Be it known that I, J AMES EDWARD J oren, a citizen of the United States, residing at Hoboken, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement-in Arc-Lamp Hangers or Supports, of which the following is aspeci'lication.

This invention relates to an improved arclamp hanger designed principally for supporting street arc-lamps that are usually suspended from mast-arms extending from posts or other suitable supports and'its objects are to provide a strong, durable, safe, and inexpensive construction in which a thorough insulation is provided, thus rendering the hanger free from the objections common in such devices now in use.

A further object of the invention is to provide a construction in which the insulation is thoroughly protected from the elements of the weather and also missiles oftentimes hurled through the air and aimed at such points for the distinct purpose of destruction, and still a further object is to provide for the use of a wire supporting-cable instead of rope, as now used, and by which the hanger and lamp are lowered and raised for the purposes as will readily appear to those skilled in the work towhich my invention relates.

With these brieiiy-stated objects in view the invention comprises an arm having an insulating member or sleeve carrying a bolthook to which the lamp is connected, a hood arranged over and completely protecting the insulation, and a safety device designed to catch and support the insulation should the arm, which is of wood, be broken or burned, as is oftentimes the case, thus thoroughly and fully providing a safe construction that will prevent the lamp falling and also providing protection for the workmen employed in keeping the lamps in condition or pedestrians passing under or who may be in the immediate vicinity of the lamp.

The invention also comprises certain details of construction and peculiar combination and arrangement of parts, as will be fully set forth in the following specification and pointed out in the claims, reference being had to the drawings, in which- Figure l is a perspective view of a crossarm having my improvement applied thereto Figs. 2 and 3 are detail perspective views of the insulating sleeve or member. Fig. 4 is a detail sectional view drawn about on the line 4 il of Fig. 3. Fig. 5 is a sectional view drawn through the cross-arm and illustrating my improvement in position, the latter also being in section. Fig. 6 is a deail sectional view drawn on the line 6 (5 of Fig. 5. Fig. 7 is aplanview ofthe insulating member, showing'the bolt-hook in section and illustrating the arrangement by which the lamphook is prevented from rotation, the hood being shown in dotted lines. Fig. 8 is a detail plan view of a portion of cross-arm. Fig. Q is a detail perspective view of the safety-plate arranged. under the cross-arm, and Fig. l0 illustrates a slight modification of construction.

In the drawings, A designatesa wooden cross-arm having insulating-knobs B at each end, to which the current-wires C are connected that run to the lamp D, all of these parts being of the ordinary construction.

Centrally of the arm A is produced a cylindrical bore A', having notches AZ at its upper edge, and Vlitting within the bore is a glass insulating sleeve or member E, the body portion E of which is cylindrical and having a semispherical-shaped head E2 of somewhat larger diameter than the body portion, the lower side of the head being recessed, as shown at E, providing a continuous flange or petticoat E4, and immediately adjacent the head the sleeve is enlarged, as at E5, to provide a shoulder E, from the lower sides of which depend lugs E7, that are designed to rest in the notches A2 in the arm to hold the sleeve against rotation. The extreme lower end of the sleeve is recessed to provide a flange or petticoat E, and extending entirely through the sleeve and head is a bore El, through which the shank'of the lamp-hook F extends.

A semispherical-shaped hood G, centrally apertured, as at G, is arranged upon the head of the sleeve and is connected to the bolt F, which projects through the aperture, by clamping-nuts G2 and G3, the latter being arranged within the hood and rests within a non-circul ar recess E11 in the upper surface of the head and prevents the accidental rotation of the hook, but permits the hook being turned so that the lamp may be turned, which is often desired, r especially when a shaded surface is produced upon the globe.

IOO

A substantially inverted-V-shape bailhandle H or hanger-bolt is connected to the cross-arm and has its ends extending in parallel directions through apertures arranged in the cross-arm upon opposite sides of the bore A, so that the upper portion of the hanger or hook will straddle the hood and sleeve, and arranged upon the lower ends of the handle or bolt is a plate l, having a central opening through which the lower end of the sleeve E projects, the said plate being held in position by nuts H/, threaded upon the lower ends of the handle or bolt. This plate forms a safety-catch which is designed. to catch and support the sleeve should the arm be broken or burned and prevents the lamp dropping to the street, and, as clearly shown in Fig. 5 of the drawings, the central portion of the plate is slightly depressed to prevent the hood coming in contact therewith should the arm A be destroyed. A wire cable J isconnected to the bail-handle orl hook and is extended over pulleys carried by the inast-arm and by which the lamp and hanger is held. suspended from the mast.

In practice I may construct the hood G with a threaded or smooth aperture and having an interior non-circular boss or hub G4, which would serve the purpose of the nut G3, this feature being shown in Fig. 10 of the drawings.

It will be particularly noted that by supporting the lamp-hook from the insulatingsleeve all danger of short-cireuiting of the current is positively avoided and, further, that by having the supporting bail or hook to straddle the hood it will be impossible for l the sleeve or hook to be disengaged from the arm unless the bail or hook is removed from the arm, thus'preventing accidental displacement; but enough from between the hood and the bail is left to permit the hood being elevated sufficiently to allow the nut G3 to clear the upper surface of the head, so that the lamp may be revolved and the light directed in any particular direction. It will also be seen, and especially by reference to Fig. 5 of the drawings, that the insulating sleeve or member is thoroughly protected from the elements of the weather, and by the arrangement of the flanges or pettieoats a greater surface of insulation is provided and the water will readily drop from the hood, head, or end of the sleeve without contacting with the hook, and, furthermore, the hood not only protects the insulation against y the elements, but also completely covers it and prevents breakage by missiles or falling objects.
