LAMr-BuLB-TILTING DEVICE.

1 Application vrna october 29, 192e. serial No. 420,521.

To' all whom t may concern.

Be it known that I, WILLIAM F5 Parsons', a citizen'of the United States, residingv at Cleveland in the countyfof Cuyahoga and State of hio, 'have'inve-nted a certain new and useful Improvement in Lamp-Bulb-Tilting Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates generally to automobile lamps and more particularly to the manner of arranging the lamp socket within the lamp body so that the incandescent lamp can be thrown out of focus and the rays of light deflected when desired, in order to avoid the disagreeable glare, incidental to the use of the commercial filament with a parabolic reflector, and quickly and easily returned to its normal posit-ion for distant roadway illumination. i

With these objects in view, the inventio consists in pivotally mounting alamp socket in a sleeve carried by the reflector and providing means operated from the dashboard for tilting or rocking the lamp so as to throw it out of focus and thereby prevent the glare, and the invention also includes means for returnin the lamp to its normal focused position. he invention also consists in providing for the longitudinal adjustment of the socket so that the lamp can be properly focused. The invention consists also in certain details of construction hereinafter fully described 'and pointed out in the claim.

In the drawings forming a part o'f thi specification, Fig. 1 is a plan View showing the practical application of my invention; Fig. 2 is a sectional elevation showing a portion of the lamp body and reflector and the adjustable and tiltable socket are Aranged in the reiector, said socket being shown in its normal position for distant road lighting; Fig. 3 is a similar view showing the socket tilted so as to throw the lamp out of focus; Fig. 4; is a plan of the. socket and focusing means; Fig. 5 is a detail view of the operating cables; and Fig. 6 is a detail view of the locking means.

In the practical embodiment of the inven` tion, I employ a lamp body l0, having a re-\ Hector 11 arranged therein, said reflector having a sleeve 12 inserted in its extreme rear end, the sides of the sleeve being horizontally slotted as shown at 13, and mounted in vthis sleeve 12 is the socket 14 which carries the incandescent lamp l5, and this socket la is pivotally connected to the sleeve by pivots 16. A coiled Spring 17 connects the rear end of the socket with the lamp body, said spring normally holding the socket horizontal.

For the purpose of tilting the socket and lamp against the tension of this spring I employ a rocking member, which in turn is actuated by means of a cable or other mechanism operated from the dashboard of the automobile. 'Ihe rocking member preferably comprises the bell crank arms 18, pivoted at 19 to a nut 20, and pivotally con nected at their forward ends 2l to the rear end of the socket, and the lower rear ends of said bell crank arms are connected by a piece 22 to which is attached the cable 23, passing into the lamp body through the guide eyelet 24e.

The nut 20 is mounted upon a screw or bolt 25 which passes through the rear end of the lamp body, and this screw can be turned so as to move the nut backward or forward, and thereby shift the focus of the lamp along the axis of the reflector.

The cable 23 passes around suitably placed sheaves 27 mounted on the frame and is attached to a lever 28 pivoted at 29, and operated by a pull rod or cable 30 connected to a handle 3l working through a slotted plate 32 on the dash, said handle having a notch 33 so as to lock the handle or hold the same in its pulled out position.

When the handle 31 is pulled rearwardly, the cable is drawn rearwardly, pulling down upon the bell crank arms, thus working the member and tilting or rocking the socket and lamp so that the lamp is moved up\ wardly out of focus, and being thrown close to the upper half of reflector, the rays of light will be thrown downwardly and the troublesome spreading and glaring rays eliminated.

The lever 28 is preferably centrally arranged and has a cable connected to each end so that one handle will be suflicient to work both lamps.

A spring 34 connected to the end of lever 28 serves to return said lever to its normal position as soon as the handle 3l is released. The upper inner end of the sleeve l2 is cut away as shown at 12a to permit the socket to swing upwardly and the sleeve is slotted horizontally as shown, so gislto permit xp, longitudinal movement of the socket dining its ktilting movement as most lolqegyrly shown in Eiga-2 and 31" e Itvvillthils be seen that I provide ai simple and elicient means for quickl rnd gags. ily throwing the lamp into Siieli a"fiosit'in With reference to the @fleet/olif, thei'tthevigys of light will be thrown downminstead of erward and .theleby eliminate the 'difiegiteeeble .glare Having thills, described my 4rivellwelfl,51thet l claim is:
