Specification of Letters Patent.

Patented Apr. 8,1913.

To all whomz't may concern:

Beit known that I, VVrLLIAM T. JON-ES, a citizen of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Lamps; and 'Ido 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, reference being hadto the accompanying drawings, and to the characters of reference marked thereon, which form a part. of this specification. v I V I,

This invention. relates to pillar lamps especially designed for use upon' limousines but adaptable for other purposes, and-con- .sists in'the construction and arrangementof parts hereinafter more fully set forth and pointed out particularly in the claims.

The primary object of the invention is to produce a pillar lamp of pleasing design wherein the arrangement is such as to afford acombined reflector and shield which may be readily adjusted so as to protect the eyes of the driver from the rays of the lamp,-

and at the same time direct said rays in a manner to assistin illuminating the road in front and at theside' of the car.

moval from the bracket.

and. convenientmethod of assembling the parts, and for rendering the shield and reflector movable with'the lamp globe to facilitate the, adjustment thereof.

A further object is to provide for mounting the globe .in a manner to obviate the liability of breakage and-facilitate its resupporting arms of the The above objects are attainedby the structure illustrated in the accompanying drawings, in which y Figure "1 is an elevation of alamp embodying my invent-ion, showing by dotted lines the employment of the cap and lower and the globe withdrawn upon the cap pre-' paratory to its removal. Fig. 5 is an enlarged fragmentary viewin section showing the upper end of the globe in contact with A further object is to provide a simple- .the rubber washer carried at the perimeter of the circular plate or disk in the upper portion of. the lamp, and inwhich the socket of the bulb is mounted. Fig. 6 is ,a horizontal section'through the bulb socket v as on line 6-6 of Fig. 5, showings. clamping ring embracing said socket'to which the combined reflector and'shield is attached.

' Referring to the characters of reference, 1 designates a bracket adapted to be attached to a fixedsupport 2, as shown i-n -Fi-g'. 3, by means-of machine screws 3 which pass through said support and entertapped-aper tures in said bracket. This method of attaching-the bracket removes all projecting parts, from the face thereof. Atthe end of said bracket it is provided-with extend- 'ing feet 4 to ,afford the necessary bearing surface. The upper end of the bracket 1 is provided with a socket 5, as shown in Fig. 2. F ixedly secured in said socket and extending therefrom is an upper tubular arm 6 which curves-outwardly. Mounted upon and carried by the u per end of saidarm is a hollow head 7. n the lower por tion of the head, 7 is atapped recess .8 into which screws the threaded stem 9. of'the hood or cap 10 of the lamp. The cap 10 is dished and is adapted to receive theupper endof the glass globe 11. r

The lower end of the bracket 1 is prowided with a tapped aperture into which is screwed the threaded upper end. 12 of the lower curved arm 13., thereby establishing a jointed connection between the lowerv arm and bracket which enables the free end of said arm to be swungin the arc of a horizontal circleas= illustrated by dotted lines in Fig. 1 and. by solid lines inFig. 4.

Mounted onthe lower end of the arm 13 is avfitting 14 havinga socket in the top thereof adapted to receive the reduced lower end of the lamp globe.

The socket 15 of the electric bulb 16 is mounted in the circular disk ,17 so as'to cause said bulb to depend centrallytherefrom. Connected to the socket- '15 are the service wires 18 which pass through the head], the tubular. arm 6, andthrough the bracket 1, as shown in Fig. 2. The service or conductor wires 18 serve to effect a flexible connection between the cap and disk 17 and to hold said disk within said cap.

The disl: 17 is adapted to close the upper 7 end of the globe and is supported thereon in lot such position as to cause the bulb to tie pend properly within the globe of the lamp, there being a washer of rubber or other com,- pressible material 19 interposed between the circumferential flange of said disk and the top of said globe. By employing. a compressible washer in this manner a cushion is interposed between thedisk 17 and the top of'the lamp globe which obviates the liability of breakage and at the same time effects a tight joint between said parts which. excludes dust from the interior of the globe.

For a like reason thereis interposed between the lower end of the globe and the fitting 1 1 a compressible washer 20 which 7 lies in the recess in said fitting, and upon which the lower end of the globe rests, as clearly shpwn in Fig. 2. To secure the lamp globe between the ends of the supporting arms of the bracket, the cap 10, when the parts are properly in position, is turned so as to screw its threaded stem 9 out of the tapped recess in the head 7 thereby forcing it downwardly onto the disk 17 and in turn causing the washer 19 on said disk to bear forcibly upon the upper end of the globe. This downward pressure exerted by the said cap also firmly seats the lower end of the globe in the fitting 14 upon the washer 20,

thereby securely mounting the globe between the ends of the curved supporting arms in i a manner to obviate the liability of breakage, and at the same time eliminate all rattling of the connected parts.

Mounted upon the socket 15 is a split collar 21, through the ears 22 of which passes a clamping bolt 23. Hanging from said bolt is a combined reflector and shield 24 which is concavo-convex in form and provided with.a polished inner face. It will be noted that the collar 21 is vertically adjustable on the socket 15 whereby the reflector may be adjusted toproperly focus the burner therein. The bolt 23. serves as a pivot on which the reflector may be swungto cause it to project the rays of light at the desired 7 angle.

The friction created by contact between the top of the globe and the rubber washer 19 is such as to cause arotation of the disk 17 when the globe is. turned and a consequent rotation of the socket and reflector. By this arrangement the reflector may be so adjusted or disposed by. a rotation of the globe as to cause it to shield'the eyes of the driver from the rays of the lamp, an ar rangement of material importance in pillar lamps which are usually located on each side of the drivers seat and nearly in line with his head. The reflector is of such shape that even when turned to a position to shield the eyes of thedriver itwill still project the rays of light forwardly and to the side. This method of adjusting the re- -flector and shield-is very convenient as it does not require that the lamp be opened for this purpose.

When it is desired to remove the globethe stem of the cap is screwed upwardly Into the recess in the head- 7 such distance as to" enable the bottom of theglobe to be lifted from thefitting' let when the-arm 13 may be swung to one side upon its threaded connection with the bracket 1, as shown in Fig.

4, allowing the, globe to be freely removed,

the opening in the top of the globe being of suflieient size to allow the reflector to pass therethrough.

It has been previously explained that the curved arm 6 is rigidly secured in the bracket 1. assembled as shown in Figs. 1 and 2 and the cap screwed downwardly over the upper end of the globe all of the parts are firmly held in place.

Having thusfully set forth my invention, what I claim as new and desire to secure by Letters Patent, is

1. A. lamp comprising supporting members, a globe held at its ends between said members to rotate, a bulb socket member connected to said globe to turn therewith, and a reflector mounted on and rotatable with said socket member as the globe .is turned.

a globe adapted to be mounted between said arms and supported thereby, a member car- ;ried by=one of the arms movably connected therewith to enable it to be moved'into'engagement with said globe, and one of said supporting arms being movably mounted to enable itto be swung from supporting re lation with the globe of the lamp.

3. A lamp comprising a bracket, sup ort-' ing arms mounted thereon, 'a lamp glo 'e, a

fitting on the lower arm to receive the ,bot-.
