Application filed February 21, 1921. Serial No. 446,737.

To all whom it may concern:

Be it known that I, ARTHUR L. Storms, a citizen of the United; States, residing at New Haven, in the county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Handlamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to portable electric lamps comprising 'a casing, a battery and an incandescent lamp mounted therein, and a contact device on the casing by which the flow of current from the battery through the lamp may be controlled at will.

In a portable lamp of this character, it is desirable that the user shall be able to flash the lamp, that is, light it for short periods of time, as in signaling, or for such length of tinie as it is convenient for the operator Y to hold his thumb on the contact device. It is also desirable that means be provided for closing the switch to light the lamp tor a longer period of time and without the need for continuous thumb pressure on the con tact mechanism. 1

It is an object of the present invention to provide a hand-lamp with a contact mechanism so arranged that the lamp can be flashed or can be permanently lighted, desired, but with the additional .feature that the contact mechanism cannot be inadvertently locked in closed. circuit position through accidental pressure on the contact device. This permits the handlamp to be carried about \vith tools or in the pocket of an automobile door without the danger that when the lamp is needed its battery will be found exhausted because, through accident, the switch .had been closed and the lamp had been'liglited without the knowledge of the user.

Other objects and advantages will become apparent from the following description, which is to be taken in conjunction with the accompanying drawings, wherein Fig. 1 is a view in elevation of a handlamp embodying my invention.

Fig. 2 is an enlarged broken view thereof in vertical central section, partly in elevation, on the line 2-2 of Fig. 1, showing the circuit closing device in its open circuit pa sition.

Fig. 3 is a view corresponding to Fig. 2 in the closed circuit position.

Fig. 5 is an enlarged broken view iii transverse section on the line 55 of Fig. 2.

Fig. 6 is an enlarged broken view of an alternative form of my invention showing the exterior of the contact device.

Fig. 7 is an enlarged broken view thereof in central vertical section partly in elevation showing the contact devise in its open circuit position. I

Fig. 8 is a corresponding view in closed circuit position. f Fig. 9 is an interior view corresponding to Fig. 6, as shown by the arrows 9-4) of Fig. 7. I

Fig. 10 is an enlarged brokenview in transverse section on the line 10"-1O of Fig. 7. v

in carrying out my invention as herein shown I employ a tubular sheet metal 20 having an aperture 21 in the side thereo't surrounded by a slight, substantially plane rim 22 formed from the metal 01'' the case. In the aperture 21 is located a flat pushbutton 23 formed from the material (it a strip-like sheet metal spring-contact 2% which lies longitudinally, snugly agz'iin t'the inner surface of the case, and is taste the same by a rivet 25 the lower end of the contact 2%. Near the upper end of the contact 2 L it passes under a sheet metal retaining bridge 2-6 rigidly attached to or integral with the interior oithe case 20and adapted to prevent lateral movement of the strip while permitting radialmotion thereof.

The strip 245 is longitudii'ially slotted as at 27 for the reception of a slide In the preferred form shown in Figs. 1 through 5 the slide 28 is a radially arranged piece otsheet metal which rises through a pair of corresponding slots 29 on opposite sides of the aperture 21 and has at each end a knurled operating ear and a transversetslo't 30 to receive the case 20 at the ends of the slots 29, whereby the slide is held in place.

The distance between the bottoms of the slots 30 is less than the distance between the ends of the slots 29 so thatthe slide 28 is limitedly slidable relative to the, case 20, but

the slide 28 just fills the slot 27 so that it is held against longitudinal.motion so long as the parts are in the position shown in Fig. 2;

In the alternative form, shown in Figs. 6 through 10 the slide 28 is an I shaped piece of sheet metal lying longitudinally flatwise against the inner surfaceof the case 20 and in a corresponding slot 31 in the spring-contact strip 24, whereby it is held. against longitudinal movement. The slide 28 is held in place by inturned lugs- 32"formed at the bottom of the side walls of a hollow, knurled thumb-piece 33 located on the outside of the The side walls of the thumb-piece pass through longitudinalslots 34 in the casing; In this way case 20 just above the rim 22.

the thumb-piece 33 and the slide 28 arelield in place and since the slots 34 arelonger than the side walls of the thumb-piece,.the

latter is mounted slidably, relative to'the case, although, in the position of the parts shown in Fig. 7, such motion is prevented by the fact that the slide 28 fills the slot 31 of "the spring contact 24.

. 1111 other details the construction is well known and old in the art. The tube 2O is provided atgits rearend with the customary is screwed .into the threaded central aperture of a metallic reflector 39. The reflector is heldin position by having its outerrim,

' which is covered by an insulating strip .40,

gripped between the inturne-d edge of an enveloping cup 41, which is attached to the upper end of thetube 20, and an inwardly -'projectingflange 42 of the lens. holder 43.

-A lens 44 is held betweenthe' flange 42 and the spun over rim 45. V

In its normal position as shown" inl ig. 2 the upper end of the contact'24 is ad- "jacent to'but not quite in contact with the reflector 39. Thusthere is a nearly continuouselectrical'circuit through the parts as follows z-thecontact24, the case 20, the cap 35, the spring 36, the battery 37, the bulb 38 and the reflector 39,. This circuit is interrupted only by the gap 'betweenthe contact 24 and the reflector 39.

'By pressure on the push-button 23 the contact 24 may be sprung inwardly to con tact at its upper end with the reflector, thus closing the circuit and lighting the lamp as The other long as the pressure is maintained. To obviate the necessity of maintaining the pressure manually, the slide 28, which is freed from the restraint of the slot 27 or 31 by the inward movement of the contact strip 24, may he slid upward by manipulation of the knurled portions of the slide, thus holding the spring contact 24 inits circuit-closing position, as shown in Fig. 3, until the lock 28'is returned to its normal position when the latter snaps into the slot 27 or 31 again,

releasing thespring contact to spring back into circuit breaking position." 7

The constructions disclosed may be varied in many ways without departingfrom the principles of the invention.
