UNITED STATES PATENT OFFICE.
CHARLES E. GODLEY, F DETROIT, MICHIGAN, ASSIGNOR TO EDMUNDS AND JONES y CORPORATION, OF DETROIT, MICHIGAN, A CORPORATION OF NEW YORK. Y
TAIL LAM?.
Application filed November 17, 1922. Serial No. 601,497.
To all z 0/1.0m t may concern.'
Be it known that I, CHARLES E. GODLEY, a citizen of the United yStates,and residing at Detroit, in the county of Wayne and i State of Michigan, have invented a new and lImproved Tail Lamp, of which the followinU is a specification. f
A his invention relates to electric lamps which are usually mounted on the rear ends 1 of motor vehicles to illuminate the license plate and to indicate thev presence of the vehicle, and its object is to provide a lamp'of this character which may be constructed of a minimum number of parts andl at low cost, u and which will be dust-proof. y
This invention consists in the details of construction illustrated in the accompanying drawing and particularly pointed out in the claim.
In the drawing Fig. 1 is a section of this improved tail-lamp on the line 1-1 of Fig. 2. Fig. 2 is a front elevation of the lamp. Fig. 3 is a section on the line 3-3 of Fig. 1.
Similar reference characters refer to like parts throughout the several views.
The present lamp consists of a body, a connector sleeve mounted therein and supporting a light bulb, a combined lens and shell of glass extending into the body and 3 closing one end thereof, means to hold the parts together, and means to seal the joint between the inner vend of the lamp glass and Vthe end of the body.
The body consists of a cylindrical shell 1 of sheet metal having an end 2 in which the thimble 3 is mounted to support the well known connector sleeve 4. A conductor 5 and the base 6 of the bulb 7 extend into this connector. vHoles may be formed in this end 2 to receive the screws 8 by means of which the lamp may be attached to any desired support.
The lamp glass consists of a tubular portion 10 and an end 11 integral therewith Af? which end may have any desired form, that shown being a dome with circular shoulders on its innerside. The shell 1 of the body is formed lenlarged Outer end12 terminating in an inwardly inclined flange 13 to receive the locking ring 14 of spring wire which holds the glass in place'.
A packing ring 16 of rubber, paper or other suitable material is placed between the end of the tubular portion 10 of the lamp glass and the end 2 of the body and thus efl'ectually seals the lamp and renders it dust proof. The shell 1 has an opening 17 through which light may fall on a license plate in the usual manner. The tongues 18 may be formed adjacent the opening 17 and be bent to engage the glass tube to help position it. To increase the projection of light through the window or opening 17 and also through the lens, I preferably make the shell 1 of the body sufficiently larger in diameter than the tubular glass portion 10 so that a band 19 of light reflecting material may be disposed between them as shown in the drawings. Then I fo-rm the shell 1 inwardly at the two longitudinal edges of the said window opening so as to afford inwardly directed tongues having tip portions in fiatwise engagement with the tubular glass portion 10. With the tongues thus formed, as shown in Fig. 3, their inwardly directed parts engage the ends of the reflecting band 19 so as to prevent this from moving out of position circumferentially of the lamp body.
At the same time, the tip portions by their engagement with the tubular glass portion 10 aid in clamping the shell tightly to this glass portion and prevent dust from entermg.
glass after which a ruby glaze may be applied to the endthereof.l
A lamp glass in which the tubular body portion and the circular end portion are in y tegral avoids the. joint that can seldom be made tight except by expensive lgrinding The lamp glass may be molded by placingA find which, unless a packing cushion is ued,A
is liable to become noisy. The oiroumen ential rib 2O at the outer edge of the ciroular end 11 may be omitted if desired.
fIfn a lamp, a glass member' comprising in integral formation a lens and a tubular Wall portion, a metal shell housing the Said Wall neeeaee portion and having a bore larger than the outside diameter of the Said Wall portion the metal shell having a Window opening therein, und a light reflecting band disposed between the metal shell and the tubular Wall portion7 on the side ofthe lamp opposite the Window opening.
