N. J., assignor to Bright StarBattery Company, Hoboken, N. J., a corporation of New York Original application 345,7 53. Divided March 9, 1929, Serial No. and this application August 5, 1931. Serial No. 555,313
3 Claims. (01. 24010.66)
This invention relates to flashlights and provides improvements therein, and is a division of my application Serial No. 345,753, filed March 9, 1929.
In my application for patent, Serial No. 335,- 168, flled January 26, 1929, and Serial No. 335,- 774, flied January 29, 1929, I have described and claimed flashlights having a plurality of lamps, in which the lamps may be of diflerent colors, and be illuminated singly or together, and be used for signaling and other purposes. This and my other said inventions provide a multiple lamp flashlight of improved construction in respect to its compactness, ease and facility of assembly, convenience of replacing batteries and lamps, simplicity and general excellence of construction and performance.
The present invention provides a compact and simple arrangement of a plurality of lamp sockets in combination with a head having a cupped reflector, and providing simple and effective protection against grounds. In the present embodiment the said reflector forms the support for the lamp-sockets.
The invention further provides improved means for connecting the sockets to switch leads, and for making connection between the lamp terminals which connect with the carbon pole of the battery.
Other features of improvement will be pointed out in connection with the detailed description Which follows.
An embodiment of the invention is illustrated in the accompanying drawing, wherein:--
Figure 1 is a perspective view, with parts broken away, of one embodiment of my invention.
Fig. 2 is a vertical sectional view of the construction shown in Fig. 1. Y
Fig. 3 is a bottom plan view of the disk carrying the contacts for making connection with terminal contacts on the lamps.
Fig. 4 is a sectional perspective view of the parts shown in Fig. 3.
Fig. 5 is a detailed view, showing in section and perspective the reflector having the lamp-sockets connected thereto.
Fig. 6 is a perspective view (with parts broken away) of a slight modification of the parts shown in Fig. 3.
Fig. 7 is a diagrammatic view showing the circuit connections.
Referring to said drawing, numeral 10 designates the body or casing for holding the battery, and usually of elongated cylindrical shape. The bottom may be closed by the usual screw cap 12 terminals of the lamps.
The head 14 contains a plurality of lamps R,
G, W, preferably of different colors, as for example, red, green and white, adapting the device for signalling, as hereinafter more fully explained.
Numeral 20 designates a cupped reflector adapted to project condensed light from one or all of the said lamps R, G, W. Numeral 22 designates a glass cover plate in front of the reflector, and the plate 22 is conveniently held in place by a threaded ring 24 engaging corresponding threads 25 on the head.
As shown in Fig. 2, the reflector 20 may be provided with a flange 27, which flange 2'7 may be pressed down against the head by the cover plate 22, and thereby hold the reflector in place. Insulation 29 may be provided between the flange 27 and the said head, and insulate said reflector from the head, where the head is of metal, as is usual.
Numerals 31, 32, 33 designate the lamp-sockets which are secured to the reflector, and are electrically grounded thereon.
Behind the reflector is a disk 35, conveniently of insulating material, having thereon a stud or the like 37 adapted to make contact with the carbon pole of the battery. The stud 37 has in sliding contact therewith a pin 39, which extends throughthe said disk 35, and is adapted to bear resiliently against the said reflector 24, so as to distribute current through the said reflector and sockets 31, 32, 33, to the threaded,
A spring 41 serves for pressing the said pin 39 against the reflector.
The said plate 35 also sustains the upward thrust of the said battery, and for this purpose it is securely fastened in the upper end 17 100 of the said casing 10. For securing the said plate 35 in the end portion '17, the said end portion may have an inturned flange 43 on which the said disk 35 rests,and above the said disk 35 there is preferably arranged a split resilient 105 ring 45 adapted to extend into a groove 47, here shown as in the neck portion 15 of the said head. The spring 45 bears against the upper side of said disk or plate 35 and holds it'securely against upward displacement,
and thereby relieves the '110 2 lamps and lamp-sockets and reflector from the upward thrust of the said battery.
The said disk 35 is preferably provided with openings 50, 51, 52 corresponding to the position of the sockets 31, 32, 33, through which, moreover, the said sockets are adapted to pass, so as to properly'position and hold the said sockets against angular displacement. The underside of the disk 35 is also preferably provided with contact strips 55, said openings 51, 52, and adapted to provide a resilient spring contact for the center terminal contact of the lamps.
veniently fastened to the disk 35 by means of rivets 58, and conveniently have upturned ends 60 (Fig. 2) which project through slots 61in the said disk 35. The said slots 61 permit movement of the ends 60 therein, and at the same time prevent lateral displacement of the said strips 55, 56. The contact strips 55, 56 are connected with conducting strips 63, 64 leading to the switches 67, 68, the ends of said strips 63, 64 being conveniently bent over in such manner as to bear resiliently against the underside of the said strips 55, 56 on the said disk 35. The center contact. of the lamp which projects through the opening 50 may bear directly against the resilient end 65 of a conducting strip leading to the switch 69. Where the casing 10 is of metal, insulating strips '71 may be provided between the strips 63, 64, 65 and the said casing 10. One of the conductingstrips 71 may extend upwardly through a notch 73 in said disk 35, and thereby provide a guide for correctly positioning said disk 35 in the casing, invassembling, i
The switches 67, 68, 69 are connected to the zinc pole of the battery through a suitable lead '75 or may be grounded on the casing 10, and through the said cap 12 make contact with the bottom of a cell in well known manner.
To illuminate one or anotheroi the bulbs R, G, W, the switches 67, 68 or 69 are pressed. If steady lighting of one or more of these lamps R, G, W is desired, the slides '77 may be pressed over the switch buttons 67, 66, 69 and hold these permanently in position to close the circuit.
Referring to the modification shown in Figs. 5 and 6, the flange 27 on the reflector may be omitted, the reflector being held in place by the bearing of its edge against the underside of the glass cover plate 22, the reflector being pressed against said plate by the spring-pressed pin 39 bearing against the underside of the reflector.
Furthermore, the disk 35 may be provided with collars 82 around each of the openings 50, 51, 52, into which collars 82 the said sockets 31, 32, 33 fit snugly, and thereby act to hold the reflector upright and prevent the said reflector from tilting sidewise into contact withthe :head 25. The said reflector at its edge 80 is of smaller diameter than the inner walls of the head, so that there is anair space between the reflector and the head. The reflector will therefore be insulated from the head by the air space or clearance between its edge and the sides of the reflector, and by the glass pla-te'22 against which the reflector bears.
56 passing across the than that herein specifically illustrated and The strips 55, 56 are con by the casing,
' apertures in said disk to gageable with "a ing, and switches individual to said contact mem- From the foregoing descriptiomit will be seen that a flashlight having a multiple-lamp head is provided, which is so small and compact that it can be readily carried around by a person in his pocket and which avoids the bulkiness and inconvenience of construction of prior flashlights having multiple lamps. Moreover, the entire construction is such as to be adaptable for simple and expeditious manufacture and assembly.
The invention may receive other embodiments described. What is claimed is:-
