I ,ADJ'USTAIBLE LAMP-SUPPORT.

Application filed December 16, 1915. Serial No. 37,110.

To all whom it may concern Be it linownjhat we, FRED A. CULVER and .-\sN C. S'rnARNs, citizens of the United and other vehicles, and the principal objects thereof are to provide a construction "forthis purpose of an exceedingly simple character which can be adjusted readily so as to vary the angle at which the light is thrown by the lamp; also to provide an attachment for this purpose that canbe used with an ordinary lamp without changing the same.

The invention also involves improvements in details of construction as will appear.

Reference is to be had to the accompanying drawings in which- Figure 1 is a side elevation of an auto mobile lamp and its support with a preferred embodiment of this invention applied thereto and shown partly in section; Fig. 2 is a side view of the attachment or bracket shown in Fig. 1; Fig. 3 is a side view of a portion of a lamp with the adjusting means applied directly to the lamp, and Fig. a is a side view of another moditied form of the invention.

The increasing diliiculty due to the use of strong head lights on automobiles has necessitated changes of certain kinds. The ordinary method of overcoming this difficulty is to reduce the efficiency of the lamp in one way or another either temporarily or permanently. So far itis believed that only one way has been found in which the full efficiency of the lamp can be retained without producing a blinding glare in the face of an approaching driver. This is done by the direction of the rays of the head-light at such an angle that at a distance of say fifty feet they will not be above 3-1,; feet from the ground. It is also well known that lamps t ey are applied to machines are frequenth not placed in the proper position-to give the light rays the proper angle either for the above purpose or for general lighting purposes. This Specification of Letters Patent.

necessitates laborious bending of the for securing the necessary adjustment.

7 The principal object of this i'nventioni's to provide means whereby the lamp can beadjusted so as to direct the rays at any desired angle to the road-bed within ordinary limits, preferablv without making any ehangesin the lmp or the support there,- for and at a very small expense. 1

Referring to Figs. 1 and 2 of the .diaw ings it will be seen thatan ordinary'supporting fork A is shown for a lamp B. It

will be understood'that this support is of:

the usual. U-shape form having two upright studs or pins a each of which is ordinarily received by a socket piece 7) on the lamp. In the form ofthe invention shown inthese two figures these parts are not altered or interfered with in any way but they are separated and between them is placed a,

supporting bracket or fitting 10 preferably in the form of a casting or forging and having a socket portion ll'with a passage 12 therethrough larger than the'pin a. This bracket 10 is also provided with a pin 13,

like the pin a.

Within the passage 12 there are three bearing points, a projection 14' on the front or rear and the ends of two screws 15 on the opposite side. The projection 14 is about in the middle of the passage and one screw is above it and the other below it. From this construction it will be obvious that the screws can be adjusted so as to cause the socket member to take any desired angular position on the suppormA within 061133111 limits. The bracket issupported on rests a carried by the fork A below each pin.

The lamp itself is supported on the two pins 1 13 of the two opposite socket members and secured to them by the usual set screws b. In this way without adding any material.

expense or altering in any way the usual construction of the lamp and its supporting fork the beam of light can be thrown at desired angle to the road bed.

In the form shown in Fig. 3.

the

vided with a projection 14; and the two screws 15", the operation being the same as the lamp socket member 6 is shown as itself proin the form shown in Fig. 1 butin this case" a a change is made in the lamp itself by the provision of a different form of socket.

In Fig. 4 an additional modification is made. In this case the lamp is applied to 2 on top and the parts are secured in their a different type of suppoeing pin a. In this case a bracket 20 is provided having socket portion at 21 in which is a smali at the bottom and flaring out at the top. This member is provided with pin 23 like the pin a. In this case the socket; member is provided. with transverse teeth desired adjusted posiiion by means of a. not 25 and a Washer 26 I The Washer 26 is provided 'ith teeth meshing with ihe teeth 2-1, the some results being secured.

.Although We. have illustrated and described only certain fori'ns oi the invention we are aware (if-the feet that many other modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore we do not wish to be limited to all the details eonstiuction herein shown and described, but

What We do claim isz- 1. The combination of a lamp support l'mving e veriicel pin its top provided with an enlarged rest, below the pin :1 bracket for supporting a lamp having a passage therein larger than the pin for receiving the pin adapted to rese on said rest, and means Wii'llil'i ziiilq'mssfige for engaging the pin at a piurrilit of points and scouring the bracket io the pin in its adjusted angw 121) positions,

2. The combination 0'? a lamp support having a vertical pin at its too provided with a, rest, a bracket for supporting a lamp having a passage, for receiving the join and adopted iio rest said rest, said passage having a centre projeoiion on its front side, and two set: screws on the rear, one above and one below the projection, extending into the passage for receiving the bracket in are gulei-ly adjusted posit-ions.

In bestiniony whereof We have hereunto set our hands.

FRED A. CULVER. JASON QSTEARNS.
