ICI. 24o-64) zclalms.

The invention relates to an electrically lighted lamp guard or shield, and more especially to an electric bulb guard or shield attachment for trouble lamps.

The primary object of the invention is the provision of an attachment of this character. wherein the handle of the electric extension trouble lamp has detachably fitted thereto a bulb shield or protective guard, which is of special conformation, so as to prevent rolling when at rest, and also to permit the hanging thereof from a support, either through suspension hooks or a permanent electric magnet, that the lamp will be properly positioned to the work during the use thereof.

Another object of the invention is the provision of an attachment of this character, wherein the shield or guard is conveniently removable. so that easy access can be had to the bulb, and also will perfectly shield the latter, the attachment being of novel construction and unique in its arrangement for safe and required services in the use thereof.

A further object of the invention is the provision of an attachment of this character, which is simple in construction, thoroughly reliable and eiilcient in operation, strong, durable, enabling the lamp to be suspended in a vertical or horizontal position, to be firm and steady in either position, and inexpensive to manufacture and install.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiments of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a vertical longitudinal sectional view through the lamp and the attachment constructed in accordance with the invention.

Figure 2 is an outer end view thereof.

Figure 3 is a sectional view taken on the line 3-3 of Figure l looking in the direction of the arrows.

Figure 4 is a side tachment detached.

Figure 5 is a side view of the attachment in its released position.

Figure 6 is a sectional view taken on the line 6--6 of Figure 4 looking in the direction of the arrows.

Figure 7 is a sectional view taken on elevation showing the atthe line I- of Figure 5 looking in the direction of the' arrows.

Figure B is l-B of Figure 1 arrows.

Figure 9 is a sectional View taken on the line 9-9 of Figure 8 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A desisnates generally an electric extension cord of any standard construction, having at one end a separable electric contact plug Ill, of the usual type. and at the other end of this cord is an insulated handle II, as best seen in Figure 1 of the drawings. This handle I I carries an electric light bulb socket I2 for electric current supply to an electric light bulb I3, which is detachably fitted within the said socket I! in the ordinary well known manner. The socket I2 is countersunk in the head Il of the handle II.

Attached to the head I4 is a carrier plate I5 which at its border formation is squared, or of substantially equilateral rectangular shape, it being made of any suitable material, flat faced, and at the border there is provided a continuous outturned rim or flange IB, the plate I5 being preferably secured to the head I4 by screws Il, although it may be otherwise fastened in place, and has a clearance for the bulb I3 at the center thereof.

Seated against this plate Il within the border thereof is a protective bulb guard or shield, involving end pieces Ill and I9, respectively, which are of square border formation, having therebetween and riveted or otherwise joined thereto, longitudinally disposed spaced outer guard rods 2U, to effect with the pieces of canopy for the bulb I3 when confined within the shield or guard proper. The rods 2li are so arranged near the edges of the pieces I8 and I9, to create a square frame formation or a flat sided shield or guard, so that when at rest it will not roll on a support when such shield or guard is placed thereon. The end plate or piece II has a clearance therein for the slipping of the bulb therethrough to the interior of the said shield or guard in replacing bulb.

Carried by certain of the rods Ill innermost thereto is a reector 2| for projection of light from the bulb Il, when lighted.

Centrally of the piece I9 is mounted a swivel hook 22, having a tensioning spring 23, the hook 'a sectional view taken on the line looking in the direction of the being outside of the guard or shield and enables the hanging of the lamp for vertical suspension thereof.

The piece Il is detachably held on the plate i through the use of bolts 2l carrying winged nuts 25, the bolts being passed through the piece and thc platel respectively.

On the laterally outermost rods 2l at one side ot the guard or shield are remotely spaced hanger hooks 28, these being four in number and are best seen in Figures 5 and 7 of the drawings, so that the lamp can be horizontally hung and supported against rolling motion when in service.

In association with the guard or shield is a permanent magnet 2l. it being iixed to a clip 28, which is adapted for detachable engagement with certain o! the rods 28 at selected sides of the shield or guard, so that the latter can be hung in stationary position by the use ci this magnet xture for support on any magnetic medium or substance. The lamp is usable with or without this magnet 21, as should be obvious.

What is claimed Ls:

1. A magnetic iixture for holding a portable electrical appliance in the form of a trouble lamp, comprising a handle, a recess in said handle, an electric light bulb socket in said recess, a carrier plate mounted on said handle. a central aperture in said plate in alinement with said recess, an out-turned rim on said plate, an electric light bulb guard having nat sides thereto secured to said plate within said ange, said guard involving outer protective rods. a clip snugly iitting a selective side and having detach able connection with certain of the rods thereof. and a permanent magnet carried by said clip.

2. A guard attachment for trouble lamp electrically lighted, comprising a flat sided open-work enclosure for a bulb of the lamp, and having an end piece, a. supporting member on the lamp comprising a flat faced plate having an outturned iange and having the end piece seated therein within said flange, means detachably connecting the member and piece together, a swivelied hook on the enclosure for vertically suspending the same, a braking spring on said hook to retain said enclosure at a iixed angle to the vertical as desired, a plurality of hooks on the enclosure for horizontally suspending it, and a permanent magnet detachably connected to the enclosure exteriorly thereof.
