the lamp impinge upon said reflector and are reflected in all directions.
The tube I is provided intermediate itsends with a hook [5 which is shown as welded ,or
brazed to the exterior of the tube, although it may be longitudinally adjustable with respect thereto; This hook is adapted to be engaged with the edge of the flange 16 which extends around the manhole ll of tanks of the character described. When thus supported, the device will occupy the position shown in Figure 2. I
Electric current for energizing the lamp is supplied through a cable [8 entering into the upper end of the tube and passing downwardly through rubber bushings l9 and 20, which ex-' eludes entrance of Water, to the lamp socket 4 where said cable has the usual connections with the lamp 9. When thus illuminated, the beam from the lamp will be reflected from the reflector l2, as indicated by rays 1', a few of which are shown in Figure 2, although, in practice, these rays Will be innumerable and will illuminate the most remote portions of the tankwith a soft light imparting a high degree of illumination without glare.
With the construction described, the device is perfectly safe for workmen, the electrical connections to thelamp, including the lamp socket are completely sealed within the'confines of the lamp mounting, so that it is utterly impossible for water to get into the lamp mounting and cause short circuiting which would render workmen liable to electric shock upon contact with the device. In practice, it is found that a stream of water .may be directed from a hose all over the device without any short circuiting or damage to any of the parts. It is quite common in practice for a stream of water to strike the lamp during its use. During the washing of the interior of the tank, the semi-spherical reflector will of course become wet, experience has shown that this does not materially affect its ability to properly reflect light to the most remote parts ofthe tank and provide adequate illumination for the workmen therein.
The light is so hooded as to not only protect it from damage by wetting with water, but to protectit from damage by contact with extraneous bjects. The tube is, in practice, fairly long so that heat generated by the lamp will rise through the tube and beradiated from the tube and thus the parts do not overheat. A workmanlcannot possibly obtain an electric shock from the lamp of this construction, no matter how wet the parts. of the device in the tank may become. Such a workman may shift the device around the flange of the tank as he walks past it and the device may bereadily raised and lowered into the tank as the workman leaves or enters it. I 1 n This invention was particularly conceived for the illumination of the interior of milk transporting tanks. I am aware, however, that it has uses in other environs and the present invention is therefore to be understood as fully commensurate with the appended claims.
Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:
, 1 An illuminating device comprising: an elongated tube, one end of Which is enlarged to form a hood the free end of which is flared, a sealed beam lamp supported within the flared end of the hood with-its axis parallel to the axis of the 7 tube, rodsextending from said flared end and supporting a semi-spherical reflector coaxial with 15 and in spaced relation to the lamp, an electric cable passing from the lamp longitudinally through the hood and tube and through the distant end of the latter, and means for supporting the tube in upright position.
2. An illuminating device comprising: an elongated tube one end of which is provided with a hood'the free end of which is'fiared, a lamp -mounting positioned within the hood and having an'openend provided internally with a heat resisting gasket, a socket positioned within said mounting and supported thereby, a lamp engag-- ing with said lamp socket with a portion of the lamp seated against the gasket of the mounting to seal the mounting against the entrance of Water at'this point, an electric cable passing longitudinally through the tube and hood and into the interior of the mounting and connected to the lamp socket, an impervious gasket surrounding the cable to preclude the entrance of water into'the mounting about the cable, and rods extending from the flared end of the hood and supporting a semi-spherical reflector in spaced -re1ation to the end of the hood and coaxial with the lamp.
"3. An illuminating device as claimed in claim 2, wherein the free end of the tube is provided with a rubber bushing to seal said end of the tube and cushion the cable against wear.
4. An illuminating device as claimed in claim 2, wherein the lamp is a sealed beam lamp.'
5. An illuminating device comprising: a tube provided at one end with a hood having therein a lamp mounting for a sealed beam lamp, a socket within said mounting, a current carrying cable leading to the socket and saidmounting being sealed by gaskets about the cable and the lamp against the passage of water intothe mounting,
rods secured to the hood and supporting a semispherical reflector coaxial with the lamp and in spaced relation to the latter, and means for supporting the hood in upright position.
