ELECTRIC LAMP.

Application flied December v. 192s. serial No. 679,146.

To 'all w71 om t may concern.'

Be it known that I, JOHN SoHUL'rz, citizen of the United States, res/idin f at New Britain, in the county of Hart ord and State of Connecticut, have invented certain new and useful Improvements in Electric Lamps, of which the following is a specification.

This invention relates to the art of illumination and has particular reference to an improved form of electric lamp ada ted for many uses, such as a hand illuminatin signal, a side or dash lamp for automobi es, a trouble lamp, or the like.

The primary object of the inventiim is to provide a'lamp of the above kind which embraces the desired qualities of simplicity and durability of construction, as well as efficiency in operation.

Another object of the invention is to provide a hand illuminating signal lam lof improved construction, having a switc so arranged and, constructed as to permit the safme being manipulated for lighting the lamp with facility and ease through operation of the users thumb when the lam is supported against the rear side of an b the inde-X and middle fingers of the users hand.

Still another object of the invention is to provide. improved means for supporting the lamp against the rear side of and from the index and middle fingers of the users hands and means cooperating with a member oi lamp upon the side or sash of a motor vehicle, whereby the lamp may serve the useful purpose of a side light or dash board light.

Other objects will appear as the nature of the invention is better understood, and the same consistsin the novel form, combination, and arrangement of parts hereinafter more fully described, shown in the accompanying drawings, and claimed.

ln the drawings, wherein like reference characters indicate corresponding parts throughout Jthe several views:

Figlure 8 is ay side elevational view showing t. e lamp applied to a bracket for acting as a side or dash lamp for vehicles.

Fi ure 9 is a substantially transverse sectiona view taken upon the line 9--9 of Figure 6 and drawn on a smaller scale.

Referring more in detail to the draw ings, the lamp embodies a cup shaped cas-l ing 5, that is open at its iront end and that has its wall enlarged and formed at this end to provide a bead 6 for seating reception of a lens plate 7 that is retained in place by a conventional form of resilient split ring 8 seated within said bead 6 against the margin of the plate 7. The closure or lens late 7 is preferably ot red glass or celluloi or signalling purposes, and as shown clearly in Figure 5, the outer side ot' the casing 5 is formed with a relatively large window or opening 9 that is closed by means of plain glass or celluloid as at 10.

Extending through and secured within an opening in the upper portion of thecasing 5 is a sleeve 11 that is inclined inwardly as shown in Figures 1 and 2, so as to extend toward the thumb of the users hand when employed as a hand signal as shown in Figure l., and that is also inclined 'forwardly 'toward the thumb at its upper end as shown in Figures Il, 5, and 8. The inner end of the sleeve 11 within the casing 5 is slotted in the usual manner as generally indicated at 12 for detachable connection with the base of an electric lamp 13. Fitted within the upper end of the sleeve 1l is a plug member liti@ i which the 'thereof wit the usual spring projected contact pins 15, adapted for engagement with the contacts on the base of the electric lamp 13,.as shown in lFigure 6. The plug memlber 14 is provided with a peripheral groove,

as at 16, in which is disposedrthe circular end portion17 of a reinforcing spring 18 that is coiled about the feed wires 19 for the lamp 13 ina well known manner, which coil spring 18 protects the feed wires from wear where they project into the sleeve 11, the circular ortion of said spring enterin roove16 oi) the plug 9 for ho ding sai eed wires so as to relieve them against pulling strains which would ordinarily cause their Withdrawal from the plugs 14. Fitted within suitable sockets in the plug member 14 are lixed

bushings

19 and 20 disposed beside openings lrovided` in said plug 14, into eed) wires are adapted to be positioned, .and threaded through the sleeve and-into the plug member 14 are

screws

21 and 22 that serve to clamp the .feed wires into engagement with said

bushings

19 and 20 for v effecting electrical connection therewith. The bushing 19 may be electrically connected with its contact 15, through the medium of the projecting sprin thereof, while the bushing 20 is norma ly disconnected, electrically, `from the contact 15 of the same. The. upper end of the sleeve 11 is closed by means of a cap 23, that is retained in place by means of a screw 22, and throu h whichprojects a lon itudinally movabtle switch element or ro 24 that is slidably disposed through the bush-- ing 20, and that has a knob or linger piece 25 upon its upper or outer end. s The switch rod 24 is normallyl pro'ected upwardly or outwardly by means o a spring 26, and the spring of the contact 15 disposed in alignment with the switch rod 24 bears against a contact late 27 disposed in line with the inner e'nd) of the switch rod 24 as shown in Figure 6. The spring 26 normally holds the switch rod 24 out of contact with the contact plate 27 and upon inward movement of said switch rod 24 the llatter is engaged with the contact plate 27,

' so as to close the circuit to the lamp 13. A

hollow slide 28 may be carried by the cap 23 for maintaining the switch rod 24 in circuit closing or depressed position. The important feature of this switch construction is that the switch rod 24 is movable lon itudinally of the sleeve 11 and exposed at te upper end of the latter in position to be engaged by the thumb of the user when the device is attached to the back of the index and fourth ingers of the users hand as shown in Figure 1, the slide 28 being mov- 'able obliquely to the longitudinal axis of the lamp casing 5 as indicated by position -of these parts as shown in Figure 7, so that .be conveniently moved over the switch rod 24 for maintaining the latter in circuit closing position.

Attached to the back of the casin 5 is an elongated plate 29 that is vertica y arranged when 1n use, and this plate has its ends outturned to provide flanges 30, an intermediate flange 31 being stamped outwardly from the intermediate portions of the plate 29, and all of said

flanges

30 and 31 being provided with elongated slots as indicated 'at 32 in Fi re 7, that are in alignment with each ot er. An adjustable elastic stra has itsu per end attached to the up er an e 30 and is slidably threaded throug the s ot in the intermediate flange 31, as well as the lower flan e 30 as shown clearly in Figures 3 and 4. n this manner, two looped portions may be formed in the elastic strap, which is indicated at 33,'for embracing the index and forengers of the users hand so as to effectively secure the lamp to said fingers and against the back of the same. The adjustable nature of the elastic strap 32 permits of applying the device to fingers of different siz'es.

A s shown clearly in Figure 3, the longitudinal axis of the late 29 is angularly related to the longitudinal axis of the sleeve 11, so that when thedevice is attached to,

the hand, the sleeve 11 inclines upwardly and inwardly so that the switch rod 24 is 'properly positioned for engagement by the thumb of the hand.

In the use of the device as a signal lamp, the lamp is attached to the fingers as specified above, and when the hand is extended above the side of the vehicle by the drivel,

he may apply a pressure u on the switch rod 24 Vso as to cause the amp 13 to be lighted, ,and the light from this lam will shine through the led colored lensl p ate 7, aswell as outwardly through the window 9 lll for presenting a danger signal and illuminating the hand of the driver. The signal will thus be effective in preventing accidents and it will thus be apparent that the devi may be also employed as a trouble lamp by reason of the light shining through the window 9.

The slot 32 in the

flanges

30 and 31 are' relatively wide, so as to accommodate the vertical upstanding member 34, of an angular sheet metal bracket 35, that is attached bymeans of screws or the like 36 to the desired part of the motor vehicle. The intermediate portion of the bracket 35 will thus actas a supporting medium for the lamp to rest upon when the end portion 34 is disposed through the aligned slots 32 of the

fianges

30 and 31,k and the lens plate 7 will' be presented toward the dash board or side of the vehicle,.so that the light will shine in, the proper direction through the side of the casing as allowed by the Window 9. When the bracket 35 is attached to the dash board, the lamp will serve effectively, as a dash light, while when the bracket is att-ached to the side of the vehicle, a device will effectively provide a side vehicle light. By providing the slider teeth `28, the lamp may be maintained lit without requiring holding of the switch rod 24 in depressed position by the operator.

It will thus-be seen that I have provided a simple, durable and efficient form of lamp that may be usefully employed `for many purposes, and that may be cheaply and easily constructed aswell as placed into use.
