ELECTRIC LAMP Filed July 29, 1940 aridnfleg/ INVENTOR ATTOR NEYS Patented June 9, 1942 UNITED STATES PATENT OFFICE ELECTRIC LAMP David C. Kinney, Kendallville, Ind.
Application July 29, 1940, Serial No. 348,227
2 Claims.
The present invention relates to improvements in portable electric lamps.
An important object of the invention resides in the provision of an electric lamp primarily adapted for use by mechanics which is designed to give greater flexibility in a lamp stand.
Another object of the invention is to provide an electric lamp including a stand which is constructed in such a manner that it may be adjusted to any desired angle or elevation so as to afford lighting facilities to a mechanic or other workman wherever he may need it.
A further object is to provide a lamp having the above characteristics that can be cheaply manufactured, easily assembled and capable of a wide range of adjustments.
The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.
In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which: v
Figure 1 is a front elevational view partly in section of an improved lamp embodying the features of the present invention.
Figure 2 is a vertical sectional view taken substantially on line 2-2 of Figure 1.
Figure 3 is a detail sectional view of a cord holding hook taken substantially on line 3--3 of Figure 1.
Figure 4 is a detail View of one section of the lamp stand as seen on line 4-4 of Figure 1.
Figure 5 is a detail sectional view taken substantially on line 5-5 of Figure 2.
Referring to the drawing for a more detailed description thereof, the lamp is generally designated by the reference numeral 8 and includes a stand supported on a base 9, said base being formed with a plurality of legs I0. Extending upwardly from the base 9 is a tubular shaft II for slidably receiving the member l2, said member being held therein by means of the set screw l3.
Carried by the upper end of the stand, by means to be hereinafter described, is an elongated substantially semi-cylindrical-shaped housing l4 having a reflecting surface on the interior thereof for the light IS. The rear face of the housing I4 carries a slotted bracket IS in which is secured a stem I1. One end of the stem I1 is formed with a head l8 as more particularly shown in Figure 4 of the drawing which retains said stem within the bracket IS, a nut l9 mounted exteriorly of the stem adapted to retain the same in adjusted position on the bracket.
The lower end of the stem I1 is formed with a ball joint 20 engageable within a socket 2| of the rod 22. It will be readily apparent that the stem l! is movable back and forth within the bracket I6 for adjusting the angularity of the housing and that the ball and socket joint 20 and 2| will permit angular adjustment of the stem I l and housing M.
The rod 22 is adjustably held within the tube 23 by means of the set screw 24 and the lower end of said tube is formed with a ball joint receivable in the socket 25 of the intermediate member 26. The member 26 is formed of a pair of sections 21 and 28 flexibly united by a pair of straps 29 forming a hinge for further adjusting the light l5 relative to the base 9. A bolt and nut 30 will retain the hinged sections in adjusted position. The straps 29 are secured to the member 26 by means of rivets or the like 3|.
The upper end of the member 26, as afore indicated, is formed with the socket 25 and the lower end of the member 28 is formed with a ball joint which fits within the socket 32 formed on the upper end of the member l2. Thus it will be seen that lengthwise adjustment of the lamp is accomplished through the rod 22 and member 2 which are adjustably held in the tubes 23 and I, respectively. Angular adjustment of the light is accomplished through the sockets 2|, 25 and 32 and further flexibility is imparted to the entire stand through the hinging of the members 26 and 28.
A wire shield 36 is hingedly secured as indicated at 3'! to the upper end of the housing M, said shield protecting the light I5. A friction clasp 38 carried by the lower end of the housing l4 retains the shield in closed position.
Workmen and primarily mechanics repairing an automobile have need for a lamp that is portable so as to be moved to various positions beneath the automobile. Such mechanics use a wheeled carrier for supporting the body beneath the automobile. In Figure 6 of the drawing there is shown a tubular member 39 having brackets 40 for attaching the same to the wheeled carrier, known in the trade as a creeper. When desiring to use the creeper the mechanics will remove the rod 22 from the tubular member 23 and insert said rod Within the tube 39, a set screw 4| being provided for retaining said rod in position. Thus the lamp will be attached to the creeper so as to give proper illumination for the mechanics working on the automobile.
From the above description when taken in connection with the accompanying drawing, it will be readily apparent that there hasbeen provided a lamp and stand, the construction of which permits it to be adjusted to any desired angle or elevation for giving proper illumination to a mechanic or other workman wherever it may be desired. If desired, the lamp stand can be shortened by the removal of certain of the sections and should occasion demand can be lengthened by the insertion of additional parts similar to th member 26.
Also it will be understood, of course, by those skilled in the art that variations in the hereinabove described device involving the substitution of substantial equivalents for the devices described are intended to be comprehended within the spirit of the present invention and that the invention is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.
What is claimed is:
1. In a, lamp having semi-cylindrical reflector, a semi-circular bracket having its ends secured to the intermediate portion of the said reflector, the said bracket being disposed concentrically of and spaced with relation to the convex surface of the reflector and having a longitudinal slot adapted to receive a slidable support element therein.
2. In combination with a lamp having a semicylindrical shaped reflector, a semi-circular bracket having its ends secured to the medial portion of the reflector, the said bracket being disposed concentrically of and spaced from the convex surface of the reflector and having a longitudinal slot therein adapted to receive a slidably adjustable support element therein.
