POCKET FLASH LIGHT .Application led February 19, 1981. Serial No. 516,914.
This invention relates to improvements in electric lamps and more particularly to portable types using primary batteries to produce a lighting current.
Such lamps have a wide field of usefulness,
particularly in cases where the light is required'only at intervals, briefly flashed and under ready control.
The majority of lamps of this class prem sent certain objectionable features, such for instance as their generally cylindrical sha e-with or without a Vbulbous headren ering them inconvenient to be carried in the pocket.`
The usual type of slidable switch control for the light is often undesirable, being prone to inadvertent movement in handling and therefore wasteful of energy.
Having these matters in mind it is an object of the present invention to provide a lamp of the flash light type of such thin flat shape as to be conveniently carried in a pocket without causing an objectional bulging appearance.
A further feature is in the provision'of a simple, direct linger pressed contact switch to control the lamp circuit by a moderate pressure and which upon cessation of pressure breaks the circuit. Y
Another purpose is to produce a fiash light of unusual simplicity and paucity of parts,
pleasing appearance, and capable-of being manufactured at a minimum of cost.
. These advantageous objects are attained by the novel design, construction andarrangement of parts hereinafter described and shown in the annexed drawing, constituting an important portion of this disclosure, and in whichz- Figure 1 is a side elevational view of an embodiment of the invention illustrating the manner in which it is used. Y
Figure 2 is a longitudinal'sectional view of the preferred type of lamp switch.
Figure 3 is a top plan view of the same.
Y Figure 4 is another loIi` 'tudinal sectional view showing a modified orm of switch. Figure 5 is a plan view of the same. Figure 6 is a similar sectional view showing a different form of lamp switch. f
Figure 7 is a plan view thereof.
Stated in general terms the device consists of a thin flat casing shaped to be comfortabl held in the'hand or disposed in even a sma pocket, the casing being of metal or non 55 metallic material, as celluloid or any of the phenolic condensate products, either molded or die formed to present two interengaging portions.
One of these portions is adapted to rew ceive a unit composed of one or more battery cells and the other to engage a socket carrying a smalll conventional incandescent v light bulb, one of its terminals being disposed in direct contact with one of the poles as ofthe batter the other terminal being bare and expose to contact by a depressible switch normally held in an inoperative p0- sition, invisible from the exterior of the casing.
Re erring in greater detail to thedrawing, a die formed or molded hollow body, generally designated by the numeral 10, is
1 shaped to receive a unit 11 composed of one,
two, three or more batteries arranged in series, the same resting against the integral bottom of the body, their upper portion -reaching outwardly beyond the edge ofthe bodyv element, this edge being inset circumjacently, ras vat 12, to receive the close-fitting so edge 13 of the upper or cover element 14.
This cover 111 is formed to present a raised circular mouth 15 and a convexly curved outer surface 16 which blends into the side walls gracefully.
Set rigidly into the open end of the mouth l 15 is a conducting sleeve 17 contracted to constitute a socket 18 at its inner portion, thesocket being screw threaded to engage the correspondingly threaded lu 19 of an in 90 candescent lamp bulb 20 w icv extends into the sleeve to be efliciently guarded by it.
At the tip of the plug 19 is one of the lamp terminals 21, while the plug body is grounded in the socket 18, acting as the other terminal. y
A spring contact 22 xed on the battery unit, serves to retain the batteries firmly in the casing and also to conduct current to the The other pole of the batteries is engaged b a. spring arm 23, see Figure 2, disposed c osel ad]acent the inner' surface o iiexib e element 16 so that upon applying pressure at approximately the point 24., the
Anner, recend of the arm 23 will make contact with the socket 18, thereby causing a circuit from the batteries through the lamp,-the circuit becomin broken upon releasing the pressure, as y vremoving the iin er from the osition seen in Figure l.
n this type ci) lamp it will be understood that the casing cover wail is moderately resilient and yielding readilyv to pressure; ii a less resilient casing be preferred the device shown in Figures 4 and 5 may be used the same consisting of a spring arm 23 in which is set a button 26 extending outwardly through an opening 27 in the element .i6 convenienti of access, the action or the contacts being the seme.
in the rncdiiication shown in Figures 6 and 7, a spring arm 23 may be depressed by e button 28 carried by a seperate dat spring 29 heldby e rivet to the under side o the cover element 18, theburtton extending outwardly through an opening Si therein.
From the foregoing it will be seen that e thin :dat lamp has been disclosed, easily operated by one of the fingers oi the hand-holding the casing, that the non-metallic casing isessentially waterproof and that the bulb is protector. from accidental injury edsctivl.
' ile 'certain preferred embodiments of this device have been shown and described, ift will be understood that changes in the orm details thereof may be mede without departing from the scope of the invention as defined in the eppended claims.
Having thus described the invention, what is claimed es new and desired to secure by Letters Petent, is
1. A pocket electric lamp comprising e thin dat dielectric casing having parallel side walls and rounded slde'edges and composed o two sections, respectively upper and lower connected midway the length of the casing, said upper section presenting a raised circular neck blending into one of the rounded side edge walls, the remaining portion of the upper wall of said section being reduced in height to present a finger receiving surface below the plane of the top of said neck, a
lamp b ulb in said upper section projecting into said neck, said ulb having a conductthe ezt-rangements, proportions, sizes and the upper section of said casing to'defiect seid sprin and cause' .Contact of sald conducto wit the base of said lamp.
2. f thin iat ldielectric casing having parallel side walls and rounded side edges and com- 4posed of two sections respectively upper and ower connected mi way the length of tbe' casing, said upper section presenting a raised circular neck blending into one of the rounded side edge walk, the remaining por Ytion of the upper wall of said section being reduced in height to present a finger receivin surface below the plane of the top of said neclr, a lampbulb in said upper section projecting into said neck, said bulb lie-ving a conducting bese end u terminal insulated therefrom, a buttery in the lower section, an electrical connection between said terminal end one of the poles of seid battery, a conductor from the other cle of the battery its end extending normal y adjacent seid base, seid conductor being resilient, and a push button movable through the top wall of the upper section operative to cause contact o seid conductor with the base terminsi of said lare p ln testimony whereor'I sr niv signature.
