Application August 18, 1937, SerialtNo. 159,664 4 Claims. (01. 240-101;)
This invention relates to portable electric lanterns. More particularly this invention relates to the type of portable electric lanterns adapted for use as a caution or safety light, and embodying an intermittent flashing device designed to further attract attention and to decrease consumption from the power source.
One of the objects of my invention is to provide a portable electric lantern of the character 10 described having a novel and improved housing construction, and means of assembly therefor, and which includes improved means for housing a plurality of battery cells.
Another object of my invention is to provide a portable electric lantern of the character described having a translucent dome of novel construction and design adapted to diffuse the rays of light from a light source within said dome.
Still another object of my invention is to provide a portable electric lantern of the character described which shall have maximum lighting life by providing a double battery circuit in parallel.
Still another object of my invention is to provide a portable electric lantern of the character described which shall comprise relatively few and simple parts, which shall be easy to assemble, which shall be relatively inexpensive to manufacture and to maintain, which shall be highly water- 30 proofed and electrically insulated, which shall be adapted to the use of standard size unit flashlight batteries, which shall be rugged in construction, yet neat in appearance and which shall operate with a high degree of efilciency.
Other objects of this invention will in part be obvious and in part hereinafter pointed out.
The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exem- 40 plified in the construction hereinafter described,
and of which the scope of application will be indicated in the following claims.
Certain features shown and described but not claimed in this application are described and 45 claimed in my copending application, Serial No.
159,663 filed simultaneously herewith. v
In the accompanying drawings, in which is shown one of the various possible embodiments of this invention:
Fig. 1 is a vertical section view of a portable electric lantern embodying my invention;
Fig. 2 is a cross-sectional view taken substantially on the line 2-2 of Fig. 1;
Fig. 3 is a cross-sectional view taken substan- 55 tially on the line 33 of Fig. 1;
Fig. 4 is a bottom plan view of the device illustrated in Fig. 3;
Figs. 5, 6 and 7 are detail views of portions of the device shown in Figs. 1 to 4 and Fig. 8 is a bottom perspective view, of reduced size, of the device shown in Figs. 1 and 3, illustrating one of its uses.
Fig. 9 is a plan view of the light transmitting I A in a manner soon to be described. The casing C may comprise a cylindrical side wall C" having a stepped construction adjacent the top thereof forming annular shoulders I 0 and II and a top wall C which may be integral with the wall C".
Fixed to the top wall C is a metallic screw shell l2 of usual construction and design and adapted to receive therein the threaded shank of an electric lamp l3. The lamp I3 is provided with an electrical contact portion I2 adapted to project thru an aperture H5 in the top wall C to contact a conductor member I4 carried by an insulated plate IS. The member l4 and plate I5 are so designed and arranged in cooperation with a switch S, as to energize the lamp I3 from a source of supply, such as for example a plurality of batteries, in a manner as fully shown and described in my said co-p'endingapplication Serial No. 159,663. As shown in Fig. 5 of the drawings, and as described in mysaid co-pending application, the plate l5 may also, if desired, support a flasher device designed-to cause intermittent flashing of the lamp iii to provide a flash safety signal light of the type designed to be used by automobilists on highways when they are obliged to stop for repairs at night, or for any other similar uses. The plate 15 also carries a pair of contact members 22 and 23 adapted to cooperate with a switch S rotatably mounted in the wall C" of the casing and constructed and. arranged as described in my said co-pending application.
Mounted on the shouldefli is -a dome G of translucent material such as glass and adapted to surround and enclose the lamp I3 projecting upwardly therein as shown. The dome G may be detachably secured to the casing C by any suitable attaching means, such as for example, a pair of screw threaded pins 25 (see Fig. 3) and which may be diametrically disposed and rigidly attached to the shoulder ll of the casing C and adapted to project upwardly therefrom. The pins 25 are received in a pair of diametrically opposed notches 26 in the flange 21 of the dome G. A pair of knurled nuts 28 may be screwed to the pins 25 to releasably retain the said globe in attachment with the casing C. To facilitate the -mounting of the nuts 28, the globe G is provided with recessed portions in the outer surface thereof adjacent the notches 26.
In accordance with my invention, I have provided means for mounting a plurality of battery cells B and B connected in series in a circular path adjacent the cylindrical wall To this end I have provided a structure which may com- 5 prise the laminated discs 3| and 32 of insulating material (or a single disc may be employed, if desired) and a plate 33 parallel to the discs 3| and 32 and connected thereto in spaced relationship by means of a pair of arms 34 which may be integral with the plate 33 at one of their ends and having their opposite ends fixed to the underside of the disc 32.
The undersurface of the disc 32 is provided with a plurality of diametrically disposed recessed areas 36 and 36' adapted to receive therein one end of the dry cells B. The said recesses 36 and 36 are provided with resilient conductor members 31 and 31', respectively, adapted to electrically contact one pole of the cells B. Interposed between each pair of cells- B is a cell B adapted to have the opposite pole thereof from that of the cells B received in a plurality of diametrically opposed recesses 38 and 38, circumferentially disposed between the recesses 36 and 36'. It is noted that each of the contactmembers 31 has an extending portion 310. thereof disposed in the adjacent recess 38, while the ends 80a of the resilient contact members 80 are disposed in the recesses 38. It is also noted that the 0 contact members 31 disposed in the recesses 36' have extending portions 31" adapted to contact the'metallic casing C. To complete the circuit thru the batteries B and B there is provided a second disc member 39 similar to the disc 32 and 35 adapted to rest upon the top wall 40.0f the base A.
The disc 39 is also provided with a plurality of spaced recesses 86 and the recesses 88 interposed between the said recesses 86. The disc 39 is slightly turned out of direct alignment'with the 40 disc 32 so that the recesses 36 and 36' of the disc 32 are in axial alignment with the recesses 88 of the disc 39 and the recesses 38 and 38' of the disc 32 are in axial alignment with the recesses 86 ofthe disc 39. A plurality of resilient contact members 81 are adapted to interconnect opposite poles of adjacently disposed batteries, in a manner similar to the construction of the member 31. To aid in positioning the battery cells B and B, the plate 33 is provided with a plurality of arcuate notches 33a in the periphery thereof to conform to the peripheral contour of the batteries. To retain the said batteries in position the plate 33 may be provided with integral extending arms 42 (see Fig. 3) provided with arched portions 42a designed to frictionally and resiliently engage the side walls of the battery cells B and B.
It is thus seen from the above described construction that the circumferentially disposed bat teries are arranged in two independent circuits 50 comprising groups of four adjacently disposed battery cells connected in series, while the two circuits are connected in parallel by means of the casing wall and the member 80. The advantage of this type of construction lies in the fact that in emergencies the device may be operated on one circuit only. Also,the life of the battery cells is thereby increased. For convenience in recognizing the two independent circuits the disc 32 may be provided with a. dividing line X or if desired each half of the disc 32 on opposed sides of the line X may be colored differently.
As will be seen from Figs. 6 and '7 of the drawings, the recesses 38, and 38' in the disc 32, and
the recesses 88 in the disc 39 are so constructed and arranged with respect to the portions 310. and a of the contact members 31 and 80 that only one end of the cells B will be able to make contact therewith. In other words, if a cell B were inserted in a reversed position, there would be no 5 electrical contact made, thus preventing a possible short circuit. It is also noted that a short circuit will be prevented when a battery cell B is reversed in the recesses 36 and 36 in the disc 32,
and in the recesses 88 in the disc 39 due to the 10' fact that the contact members 31 and 31' are disposed at a spaced distance from the center of the recesses 36 and 36' and out of possible contact with the centrally disposed terminal member of one end of the cell B. Only when the proper end 1 of the cell B is placed in the recesses 36 and 36' will there be a proper electrical contact made.
By my invention I have provided the following construction for maintaining the plate IS, the discs 3|, 32 and 39 as well as the battery cells B 20 and B in proper assembled relationship with respect to the casing C and the base A.
The top wall C is provided with a pair of spaced apertures 45. In registered alignment with the apertures 45 are the pairs of apertures I511 25 in the plate |5, 46 in the discs 3| and 32; 41 in the plate 33; 89 in the disc 39, and in the top wall 40 of the base A. By my invention I have provided a pair of relatively long rods or screws 50 adapted to be passed thru the pairs of aper- 30 tures 45, I5a, 46, 41, 89 and 90, above described, and having the heads 50a thereof adapted to abut the outer surface of the top wall 0'. The screws 50 may be retained in position by a pair of wing nuts 52 adapted to abut the bottom sur- 35 face of the wall 40 of the base A. The wing nuts 52 are designed to be received in the hollow area 53, so as to clear the bottom edge of the said base A, when it rests upon a flat surface. To maintain the proper spacing of the plate I5 with respect 40 to the discs 3|, 32, as shown in the drawings, I provide a pair of tubular spacer members 54 freely received on the screws 50, as shown, one end of which is held in abutting relationship with the plate |5 while the other end thereof abuts the 45 discs 3|, 32. A pair of nuts 55 which may be screwed on the screw 50, serve to maintain the proper spacing of the plate l5 and the discs 3 32.
It is thus seen from the above described construction that the two members 50 serve to hold 50 in assembled relationship the essential elements of my flasher device and switch members.
If desired, a pair of spacer members 56 may be provided between the screw heads 50a and the top surface of the casing wall 0'. .Also suitable 55 lock washers 51 and 58 may be employed if desired.
I have also provided means for rendering my lantern weatherproof so that it may be adapted for use in all sorts of Weather. To this end, I 60 have provided between the junction of the base A and the casing wall C", a suitable packing such as a rubber washer 59. Also between the flange 21 of the dome G and the portion ll of the top casing wall C I have provided a rubber washer 65 member 60. There is also provided rubber washers 6| between the members 25 and the casing portion H, and a pair of washers 62 between the undersurface of the base Wall 40 and the nuts 52. Also, as clearly shown and described in my co- 70 pending application Serial No. 159,663, the switch S is waterproofed, making the entire device waterproof.
clearly illustrated in Figs. 1, 3 and 9 of the drawings and which will now be described. The dome G is preferably made of translucent material such as glass and may be suitably colored if desired. It is noted that the inner. surface of the dome is constructed of a stepped formation, defining a number of circumferential ridges 65 and 66, each of which are provided with a plurality of spaced ribs 10 which are designed to diffuse the light from the lamp l3 in such manner that the rays of light will be visible from any angle and from a relatively great distance. By the above described construction, I am able to use a lamp which is of relatively small size in order to produce relatively large amount illumination. As shown in Fig. 9, the outer surface of the dome G is arranged in a plurality of rounded sectors 15 terminating in an'area adjacent the top of the dome, to further aid amplification of the illumination furnishedby the lamp l3.
As shown in Fig. 1, there may also be provided a spare bulb carrier which comprises a resilient clip member 1| attached to the plate 33 by any suitable attaching means, such as an eyelet fastener I2 as shown, and which is adapted to carry a spare bulb l3.
There may be provided if desired a receptacle 13 which comprises a substantially U-shaped metallic member provided with flanges I4 which are adapted to be fixed to the outer surface of the casing wall C". The receptacle 13'is adapted to hold a flag or similar signalling article so that my portable device may be used during the day when an electric light would be ineffective. The receptacle 13 may be provided with a ring member 15 adapted for carrying or storing the same by hanging the portable lantern on a hook when not in use;
There may also be provided if desired a mem- 40 ber I6 which may be fixed to the wall 40 of the base A and which is provided with a guideway into which there is adapted to be inserted a suitable fastening member H! (see Fig. 8) adapted for use in attaching the flasher device to an automobile to serve as a tail light upon failure of the automobile tail light, or which may be used for any other similar purpose where a light is desired.
It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above invention, and as various 55 changes might be made in the embodiments above set forth, it is to be understood that all matter hereiri set forth or shown'in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
