7 BATTERY HAND LAMP.

Application filed June 21,

To all whom it may concern Be it known that I, ERNEST, ALsoHULnR, a citizen of the United States, and residing at New York, New York, have invented the new and useful Improvement inBattery Hand Lamps, of which the following is a specification.

This invention relates to battery hand lamps of the type adapted to be lighted while held in the hand by the manipulation of a switch on the casing, and more particularly to such lamps as are provided with an all metal casing.

As such lamps are often carried in tool boxes and similar places and accidental contact is liable to operate the switch, thereby lighting the lamp and exhausting the bat tery unnecessarily, it is desirable to provide means for rendering such accidental exhaustion of the battery impossible.

One of theobjects of this invention, therefore, isto provide means for obviating the danger of accidental closing of the battery circuit by manipulation of the switch.

Another object of this invention is to provide novel'means for insulatingthe internal circuit conductors.

for supporting and centering the reflector.

Another object of this invention is to provide a lamp structure which is simple and :heap to manufacture and reliable in opera- Further objects will appear from the detail description taken in connection with the accompanying drawings, in which:

Figure 1 is a sectional view of a battery hand lamp embodying this invention;

Figure 2 is an enlarged detail view showing the structure for supporting the re fiector;

Figure 3 is an enlarged detail view showing the construction of the auxiliary circuit opening device; and,

Figure 4 is a view showing the end cap partly unscrewed so as to open the battery circuit. I

Referring now to the accompanying drawing, 1 designates the metallic casing, 2 the battery, one of whose terminals contacts with one of the terminals of the lamp 3, mounted in the reflector 4 in the usual way. The upper end of the casing 1 is threaded to receive a threaded sleeve on the housing 5, which encloses the reflector. The upper end of the reflector bears against the lower face Specification of Letters Patent.

1920. Serial No. 390,510.

upper edge of the ring 9 is adapted to engage the reflector 4 at an intermediate portion thereof, so as to support and center it in the casing. The reflector 4 is securely held in position by being confined between the ring 9 and the lens 6.

A switch 10, which may be of the construction described and illustrated in Patent No.

1287262, December 10, 1918, is mounted on the casing and in electrical contact therewith. This switch has a contact 11 insulated from the casing. A conductor 12 connects said contact 11 to a metal collar 13 mounted in, but insulated from the end of the casing by means of theinsulating collar 14'. Theconductor 12 is insulated from the casing by means of an insulating strip 15 whichis attached to the casing by means of Another object is to provide novel means and retain a coil of the battery supporting spring 24, in the battery circuit. The flange 23 is arranged to contact with a flange 25 in the collar 13 when the cap 20 is screwed home, and to break contact therewith when said cap is unscrewed.

It will be seen that when the cap 20 is unscrewed, so as to break contact between the flanges 23' and 25, it will be impossible to close the battery circuit by manipulation of the switch 10.

It will be seen, therefore, that this invention accomplishes its objects by providing a construction whereby accidental closing ofthe battery circuit may be rendered impossible. It will also be noted that novel means are provided for insulating the internal cirfurther be seen that the reflector support is of such construction as to effectively support and the reflector.

It is obvious that various changes may be made in the details of construction without departing from the spirit of this invention; it is, therefore, to be understood that this invention is not to be limited to the specific details shown and described.

Having thus described this invention, what is claimed is:

1. In a battery hand lamp having a casing provided with a metal part, alamp in the casing, and a metal reflector for the lamp, a bead on said casing part, and a metal support crimped on said bead adapted to support the reflector.

2. In a battery hand lamp having a casing provided with a metal part, a lamp in the casing, and a metal reflector for the lamp, a head on said casingpart, and a metal support crimped on said bead adapted to support and center the reflector in the casing and to make electrical contact with the reflector.

8. In a battery hand lamp having a casing provided with a metal part, a lamp 7 in the casing, and ametal reflector for the lamp, a bead on said casing part, and a metal support crimped on said head adapted 'to support the reflector at an intermediate portion thereof.

- 4. In a battery hand lamp-having a metal battery receiving casing a lamp in the easing, a circuit closing switch adapted to normally connect the lamp with the battery,

a metal end cap for the casing, and a spring adapted to support and contact with the battery, a. metal spring retainer having an inturned flange adapted to receive and retain the spring, and a contact member on the casing but insulated therefrom, adapted to contact with said flange, to complete the lamp circuit.

5. In a battery hand lamp having a metal battery receiving casing, a lamp in the easing, a circuit closing switch adapted to normally connect'the lamp with the battery, a metal end cap for the casing, and a spring adapted to support and contact with the battery, a 'metal springretainer having an inturned flange adapted to receive and retain the spring, a metal collar mounted in but insulated from the casing and connected with theswitch adapted to.

contact with said flange. Z r

6. In a battery hand lamp having 'a metal battery receiving casing, alamp in the casing, a circuit closing switch adapted to nor mally connect the lamp with the battery, a metal end cap for the casing, anda spring adapted to support and contact with the battery, a'metal spring retainer having an inturned flangeadapted to receiveand retain the spring, and a contact member on the casing but insulated therefrom, adapted to normally contact with said flange, but upon movement of the cap to'break such contact to open the lamp circuit.

In testimony whereof I aflix my-signature this 31st day of I\Ia rch,1920.
