MOTOR-METER-ILLUMINATING ATTACHMENT.

Application filed February 26, 1925. Serial No. 11,666.

To all whom it may concern Be it known that I, lino E. Srrorrr, a citizen of the United States, residing at Los Angeles, in the county of Los rtngeles and State of California, have invented certain new and useful Improvements in Motor l\Ieter-Illuminating Attachments, of which the following is a specification.

My invention relates to a lamp socket for motormeter illuminating attachments such as glolites, the principal objects of my invention being, to generally improve upon and simplify the construction of the existing forms of similar devices; to provide a device of the character referred to that is relatively simple in structure, capable of being easily and cheaply produced and, further, to provide aone piece structure that functions as a glolite lamp socket and as a holder or clamp for the sections of transparent material that are arranged over openings that constitute windows in the walls of the glolite housing.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fully shown and described and illustrated in the accompanying drawings in which:

Fig. 1 is a perspective view of a lamp holding socket and attachment embodying the principles of my invention.

Fig. 2 is a vertical section taken through the center of a glolite housing and showing my improved lamp socket and attachment positioned therein. i

Fig. 3 is a vertical transverse section taken on the line 33 of Fig. 2,

Referring by numerals to the accompanying drawings which illustrate a "practical embodiment of my invention, 10 designates the housing of a glolite or similar attachment that is secured in any suitable manner on the front of a motormeter M.

In connection with my invention, it will be understood that glolites or similar devices are associated with motormeters for the purpose of illuminating the latter at night in order that the driver of the car with which the device is associated may readily observe the position of the temperature indicating column in the motormeter.

In order to permit the vehicle driver to see through the motormeter and its illuminating attachment when observing the temperature indicating column, the front wall of the glolite housing 10 is provided with an opening 11, and arranged within said housing and covering said opening, is a section 12 of transparent material. preferably glass.

Formed in the sides of the circular wall of housing 10 are slots or openings 13 and arranged against the inner surface of the circular wall of the housing and covering these openings are sections 1 1 of suitable transparent material, preferably celluloid.

If desired, these transparent members 141; may be distinctively colored.

Secured within the lower portion of housing 10 and insulated therefrom is an electric contact member 16, preferably resilient and connected thereto is one side of an electric circuit, the other side being suitably grounded.

The socket attachment contemplated by my invention is preferably formed in a single piece from suitable sheet metal having a certain degree of resilience. The central portion of this section or strip of metal is bent to form a short vertically disposed cylindrical socket 17 having a vertical slot 18 011 one side and a vertical groove or channel 19 on the diametrically opposite side.

Formed in the lower edge of the wall of this socket immediately adjacent to the lower ends of slot 18 and groove 19 are notches 20 that are adapted to receive the studs or short pins 21 that project from the base or plug portion of a low candle power incandescent electric lamp such as L.

When the base of the lamp is inserted in the socket, the studs 21 on said base, pass through slot 18 and groove 19 and when the contact member on the underside of the base engages spring contact 16, the lamp is given a slight rotary movement, thereby positioning the studs in the notches 20, with the result that the lamp is firmly supported in the desired central position within the glolite housing. i

' Projecting outwardly and thence upwardly and inwardly from the base of the socket 17 and from points between slot 18 and groove 19, are arms 22 that are curved so as to conform to the curvature of the circular wall of housing 10.

The resiliency of the metal in these arms tends to cause same to spread apart, so that when the device is properly positioned within housing 10, said arms will press g i s t t a pa ent members 14 and firmly retain same in position to close openings 13 in housing 10.

Arms 22 are provided With slots or open-- ings 23 that practically coincide with openings 13 in the housing and thus, rays of light may pass from lamp L laterally in both directions from the housing to provide safety or warning signal lights.

Formed integral with and projecting inwardly from the arms 22, are small ears or lips 24that. are adapted to bear against the inner face of transparent member 12 and hold same firmly against the front wall of housing 10 to close the opening 11 therein.

Thus it will be seen that I have provided a relatively simple and practical one piece device that combines readily with a glolite housing and which device, when properly positioned for use, serves as a firm and substantial socket for the electric lamp used in the glolite and also serves to firmly secure in proper position, the transparent members that close to cover the light openings in the glolite housing.

It will be understood that minor changes in the size, form and construction of the various parts of my improved glolite lamp socket may be made and substituted for those herein shownand described without departing from the spirit of the invention, the scope of which is set forth in the appended claims. 7

I claim as my invention :1

1. The combination with a motormeter illuminating lamp housing having openings that are closed by transparent members, of a member adapted to be removably positioned in said housing, a lamp socket formed on the lower central portion of said member and means on said member for engaging and holding in position the transparent members that cover the openings in said housing.

2. An attachment formotornieter illuminating lamp housings having light emis sion openings comprising a centrally arranged lamp socket, curved arms of re silient material projecting upwardly from said socket and said arms being provided with openings that are adapted to coincide with the openings in the side Wall ofthe lamp housing with which the attachment is associated. i

3. An attachment for motorm'eterilluminating lamp housings having light emission openings that are closed by sections of transparent material comprising a centrally arranged lamp socket, curved resilient arms projecting upwardly from the base of said socket and ears projecting inwardly from the front edges of said curved arms for engaging one of the transparent members within said housing.v

4. An attachmentfor motormeter illuminating lamp housings having light emission openings that are closed by transparent members comprising a centrally arranged lamp socket, curved arms of resilient material projecting upwardly from said socket, said arms being provided with openings that are adapted to coincide with the openings in the side wall of the glolite housing with which the attachment is associated and ears projecting inwardly from the front edges of said curved arms for engaging one of the transparent members within said housing.

5. An attachment for motormeter illuminating lamp housings having light emission openings that are closed by sections of transparent material comprisinga centrally arranged lamp socket, said socket. being provided on one side with a vertically arranged slot and on the opposite side with a vertically disposed groove, the lower edge of said socket adjacent to the lower ends of said slot and grooves being provided with notches and curved resilient arms projecting upwardly from said socket for engaging the transparent members within saidhousing.

6. An attachment for motormeter illuminating lamp housings having light emission openings that are closed by transparent members comprising a centrally arranged lamp socket, said socket being provided on one side with a vertically arranged slot and on the opposite side with vertically disposed groove, the lower edge of said socket adjacent to the lower ends of said slot and groove being provided with notches, curved. resilient arms projecting upwardly from said socket for engaging and holding in position certain of the transparent members within said housing, said arms being provided with openings and ears projecting inwardly from the front edges of said arms for engaging and holding in position another one of the transparent members with in said housing.

In testimony whereof I afiix my signature.
