To all whom it may concern Be it known that I, VILLIAM J. DAVIS, Jr., a citizen of the United States, and resident of Chicago, Illinois, have invented a certain new and useful Improvement in Inverted Lamps, set forth in the following specification.

My invention consists of an improvement in which a lamp is disposed under a hood, the under surface of which is adapted to be used as a reflector, and which hood is imposed upon a stand which is formed of woven wire, or other open work material, the object of my invention being to procure a shaded light of such an area of illumination as to be adapted to furnish light forcleaning and other work on floors; the hood being adapted to avoid blinding the eyes of the worker and to direct the greater volume of light to the exact place where required, and the stand being of such a height as to permit the worker to carryit handily about and thus avoid the useless lighting of the surrounding overhead space.

My invention is illustrated by the accompanying drawing in which similar letters refer to like parts throughout the several views, namely:

Figure 1 is a. side elevation, in use. Fig. 2 is a vertical section on the lie 22 of Fig. 3. Fig. 3 is a plan View of the rigid hood as attached. Fig. 4 is a side elevation showing the fiddle attachment in operation. Fig. 5 is a vertical section on the line 5-5. Fig. 6 is a plan view as attached with the fiddle.

In detail, the stand a is formed of woven wire Z) and is of conical shape so as to provide an ample base a and tapers upward a suitable height to a sutliciently small diameter at the binding band cl to receive the hood 0 which in Figs. 1, 2 and 3 is rigidly fixed to the band (Z and forms a closure at the apex of the stand. Within the hood 6 is preferably an ordinary incandescent lamp f the contact end 9 of which projects upward through the hood 6 a sufficient distance to receive the contact H of the lead line i, the running end j of which connects with some convenient electric light fixture. The slack of the lead line is wound about the stand a to suit the convenience of the worker as shown in Figs. 1 and l. The inner surface of the hood forms a back or reflector for the lamp. The device is handled by the Worker by means of a bail 70 which is rigidly fixed to the top of the hood 0.

In the modification as shown by Figs. 4:, 5 and 6 the hood 6 is movablyconnected to the band (Z by means of the trunnions n n, and by means of the band 0 which is movably connected to the band on by means of trunnions 7) p. The trunnions n n and p may consist of rivets or of bolts, and preferably so tensioned as to provide suflicient frictional contact between the bands (Z and m at the trunnions n n and between the bands m and 0 at the trunnions p p, to hold the fiddle in any position desired by the worker so that the hood 6 may be tilted and the light directed in any desired direction while at the same time the stand a remains in an upright position on the floor or if preferred the trunnions may be so loosely attached that no matter how the stand a may be inclined the hood 6 will automatically maintain a horizontal position.

In the course of my experiments I made a stand in the form of a practically perfect cone, out of woven wire, and attached an incandescent lamp within the apex, but I found that it was preferable to attach a hood in the form here shown, which better shades the light from the workers eyes and which can be adapted to serve as a reflector if desired; By using the fiddle attachment the hood may be tilted to illuminate passages or other inaccessible regions to suit the convenience of the worker.

The stand may be made of any open work material or construction so long as the clownward and out-ward direction of the light is not unduly obstructed or shaded, but for reasons of economy I prefer woven wire of substantial weight and of say about an inch mesh, the same being stock material and therefore easily available.

It is obvious that the various common forms of lighting may be adapted to my stand and hood, but for adaptability, econfor tilting said hood,-'siibstantia1iy as do omy and safety, I prefer the electric lamp. scribed. 10' I claim, Witness my signature this 27th day of.
