- My invention relates to lamps'of a type adapted to be lighted by current from the storage battery of a truck for use at one side of the truck, or in any other suitable position as desired, and it has 5 for its object the provision of a new and improved form and arrangement of parts in a device of this character by which the lamp may be readily secured in position below the body of a truck or the like so as to be held normally in balanced position below its support and so'as to be capable of yielding for swinging out of such balanced position when it comes into contact with an obstruction or otherwise has pressure applied thereto. 15 It is another object of my invention to improve the construction of a lamp of this type by reason of which the parts can be produced and assembled with a minimum of trouble and expense. It is I another object of my invention to improve devices of this type in sundry details hereinafter pointed out. The preferred means'by which I have accomplished my several objects are illustrated in the drawing and are hereinafter specifically described. That which I believe to be new and desire to cover by Letters Patent is set forth in the claim. I

In the drawing, Fig. 1 is a side viewof my improved lamp including the means for mounting it in position; 9 Fig. 2 is a front face view of the lamp as shown in Fig. 1;

. Fig. 3 is a central vertical section through the preferred form of my lamp; and

Fig. 4 is a rear face view of the support by which 5 my lamp is hung in position.

Referring now to the several figures of the drawing, in which corresponding parts are indicated by the same reference characters, Ill indicates a ring formed of sheet metal and having a 40 lug l I extending upwardly therefrom, the ring being arranged for supporting the body of the lamp as hereinafter described. Attached to the lug II and rising therefrom is a flexible strap 12 formed of fiber or other suitable material, a

45 bracket l3 being secured to the upper end of the strap l2 for mounting it in position beneath the body of a truck or the like. The strap I2 is secured to the lug Ii and the bracket l3 by means of rivets l4, plates I 5 and I6 being employed on 50 the rear face portions of the strap l2 for reinforcing the structure. Between the plates I5 and I5 I have provided an electrical conductor ll to serve as a ground from the body of the lamp to the bracket 13 and thence to the body of the 55 truck or other framework, such electrical conduetor in the arrangement shown being in the form of a band braided out of copper wires and bent upon itself so as to provide a loop portion l8 therein. As will be readily understood, the strap 60 I2 and the looped conductor II are adapted to bend very readily flatwise in either direction while serving to hold the ring fairly rigidly against movement edgewise.

In the construction illustrated, my lamp comprises a dished casing member l9 formed of sheet 5 metal having an enlarged annular portion 20 at its forward end adapted to act as a stop for limiting the backward movement of the member through the ring Ill. The casing member I9 is held in position in the ring by a plurality of ribs 2| pressed outwardly in the metal of the member in rear of the ring I0 as is clearly shown in Fig. 3. The front end of the casing member I9 is closed by a dished lens 22 which fits in the enlarged portion 20 of the casing member IS, a gasket 23 being interposed between the lens and the casing member, and the lens being held in position by means of a resilient split ring device 24 which bears against an outwardly turned flange 25 on the lens and against the inner face of the enlarged portion 20 of the housing. At its rear face, the casing member I9 is provided with a forwardly extending sleeve 26 into which an electric light bulb 21 is adapted to be mounted operatively so as to have electrical connection with the casing member l9 and with an electric wire 28.

By the use of my improved construction, with the lamp mounted in balanced position below the flexible strap l2, the lamp is normally supported in such balanced position while being at the same 80 time free to move either backwardly or forwardly to a considerable distance in case it should come in contact with an obstruction or in case pressure should otherwise be applied thereto. By the use of the arrangement as shown and described for connecting the parts together, I have provided a structure which can be very quickly and easily assembled so as to keep down the cost of construction of the lamp as a whole.

While I prefer to employ the form of construction as shown in' my drawing and as above described, it is to be understood that the invention is not limited specifially to the arrangement shown, since it will be understood that changes might well be made without departing from the spirit of my invention.

I claim:

In a lamp of the type described, the combination of a bracket, a flat strip attached at 0 one end to saidv bracket'a'nd adapted to bend readily flatwise but comparatively much more stiff edgewise, a casing connected to the other end of said strip, and a flexible conductor also in the form of a flat strip and bent flatwise into the form of a loop and connecting said bracket with said casing for establishing an electrical ground connection from the casing to the bracket.
