SPOTLIGHT.

Application filed octo er 'zs, 1921. Serial No. 511,167.

To all wiz-om itmay concern V p Be itknownthat I, ARTHUR PjP iNn, a' citizen of the United States, residing at New Haven, in the county'of New Haven, State 5 of Connecticut, have invented certain new and useful Improvements in Spotlights; and

I do vhereby declarethe following ,to be a full, clear, and exact description-of the invention, such as will enable others skilled in 0 the art to which it appertains to make and use the same. w

The present invention relates to battery hand lamps of the type in which the lamp bulb is movable with respect to the reflector to change the. spread of the beam of light delivered by the hand lamp. It is an object of the 'present invention to provide a cheap, reliable and well protected means for supportingandshifting the lamp; It is a further object to provide reliable electrical connections whereby current from the battery can be delivered to the lamp bulb irrespective ofits changes in position and whereby the lamp may be flashed or maybe burned continuously, as occasion requires.

In'the accomplishment of the foregoing 1 objects, and others hereinafter; made clear, the lamp is mounted in a support which is rotatable in the casing of the hand lamp to move the lamp axially of the casing. In the prefe-red' embodiment,,the support is threaded to the front metal head of the casing and means is provided for conveniently turning the'support on its threads to advance or retract the lamp bulb.

.In the accompanying drawings- 1 I Fig. 1 is a sectional elevation of one embodiment'of the present invention;

Fig. 2 'is'a fragmentary section of the same embodiment; r Fig. 3' is a rearview of the reflector showing the three fingers by which the lamp supportis rotated;

Figs. 4 and 5 are sections on the lines 4 and'b, respectively, of Fig. 1;

'Fig. '6 isa detail of the lamp support;-

Fig. 7 is a partial section of a modified form of. lamp support.'

In the embodiment illustrated in the drawing, the hand lamp comprises a tubular casingl of insulating material which has a flaring metal head 2 secured permanently in position as by rivets 3. Threaded to this metal end is a cup-shaped lamp support 4 of insulating material having anintegral recessed. bottom.- Mounted on this bottom is a flat plate 5 of metal having ,t-t'angs" 6 struck up therefrom and passed through openings in the bottom andthere clinched over, as shown in-the'drawings.

socket 7 in which the lamp 8 is mounted and by which electrical'connection is established with the outer terminal of the lamp.

A metal cylinder 9 is mounted .on the in- Integral with plate 5 is a threaded lamp sulat'ing bottom of the support to serve as a contact, this cylinder being held by the clinchedtangs 6'of plate 5 and therefore being in permanentelectrical connection with lamp socket 7. A battery 10 of dry cells placed end to end in-series connection ,within the casing has its upper terminal 11 in concess of said bottom and bearing yieldin'gly.

tact with a flat spring 12 whichpasses against the inner terminal of the lamp. At

the bottom of thebattery is a coiled spring 13 which presses the battery forward against contact spring 12 and maintains continuous connection with the latter irrespective of rotary and forward movement of the lamp support. Spring 13 is carried by aremovable end cap 14 threaded to a collar 15 which is connected by a conductive strip 16 with a switch housing 17. Secured to housing 17 by a rivet 18 is a yielding contact element 19 having a thumb piece or push button 20 adapted to make contact with the outwardly bent end 21 of the stationary conductive strip 22 secured to the casing by rivet 23.

. The forward and inwardly bent end of strip 22 makes yielding connection with cylinder 9 while leaving that cylinder free to rotate and advance or retract with the lamp support. The thumb piece 20 of the switch mechanism can be used for flashing the lamp as for signaling by the Morse code, and a thumb piece 24 mounted to slide on housing 17 has a bent finger 25 which by disengagement from a slot in element 19 can ride over the upper face of that element and hold thumb piece 20 in depressed and contactmaking position.

A reflector 26 is mounted at the front end of the casing and is spaced from and insulated from the threaded lamp socket 7. It has a central opening through which the bulb of lamp 8 may pass. A lens 27 is spun into therim of the reflector. This lens may be a plain lens, as shown ormay have a curved face or faces. An adjustable collar 28 threaded to the .front cylindrical end of the flaring metal head 2 detachably clamps the reflector against the end of the head. Secured to the bowl of the reflector as by soldering is a metal ring 29 (Fig. 3) carry-- ing three fingers 30, each of which passes loosely through a broad slot 31 in the insulati g lamp support. These fingers serve as means for rotating the lamp support in the threaded head when reflector 26 isrotated.

bent end of conductor 22, but without interrupting the electrical connection and spring I3 advances the battery with a sliding movement to maintain electricalconnection between its terminal 11 and contact spring 12. Thencollar 28 can be tightened up and the lamp is again secured against accidental or inadvert-mentmovement of the bulb with respect to the reflector.

Irrespective of the position of the lamp support, the switch mechanism at the side of the ease, together with its associated parts, is serviceable as means for makin .and breaking electrical connection between the cylindrical contact 9 and the coiled spring 13 at the'otlier end of thebattery. All of the parts above described are easily manufactured and easily assembled and not easily destroyed or impaired by normal use, and all of the movable parts at the front end otthe casing can be taken out for adjustment or repair, or togive access to the battery as when the latter swells and becomes stuck in the tube and must be forcibly ejected preparatory to replacement by a. new battery.

If desired the cup-shaped insulating lamp support 4:, instead of being made entirely of insulating material. may be made as shown in Fig. 7 with an insulating bottom 32 on which the contact cylinder 9 is mounted.

and with a threaded metal shell 33 secured to the bottom by a flange and rivets 34. When assembled. this metal collar 33 engages with the threads on the inside of the flaring metal head 2, of the hand lamp casing. A metal tube can be used in place of-the insulating tube 1 without any changes other than that of insulating the conductive strip 22 from threads to move said lamp axially of said casing, thereby changing the spread of the beam of light from said hand lamp.
