Application Vfiled May 4, 1921. Serial No. 466,800.

To all whom t may concern.'

Be it known that I, ANeUs R. GRoss, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Cowl Lights; and I hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement inV socalled cowl lights for automobiles and its object is to provide a very simple attractive looking light which can be readily'attached to a cowl or other part of an automobile, and which when attached can be adjusted to any desired angle relative to its support. This enables the light to be attached to curved portions of the fenders or cowl, and then adjusted so as to throw the light rays in the desired direction.

Anotherobject of the invention is to provide a removable electric lamp hold-er, which holder with the lamp can be readily placed in or removed from the casing or body of the light when it is necessary or desired to change or renew the lamp or adjust tlie electrical connections. f

I will explain the invention in detail with reference to the accompanying drawings, which illustrate one practical embodiment thereof, and set forth in the claims the essentials of the invention and the novel subordinate features of construction and combinations of parts for all of which protection is desired.

In the drawings, Fig. 1 is al side view of the light showing the preferred means for attaching same to a cowl.

Fig. 2 is a front view of Fig. 1.

Fig. 3 is a longitudinal vert-ical section of the complete light.

Fig. 4; is a'detail transverse section.

Fig. 5 is a side view of the lamp holder removed from the casing. i

Fig. 6 is a longit-udinal vertical section of such holder. l

V'Ihe light shown comprises a casing or body 1, which may be of any desired size, shape and conguration, preferably made of cast metal having an approximately cylindric bore open at its outer end but closed at its inner end and, in the present instance, shown as having a reduced socket member l in its interior near its inner end for a purpose hereinafter described. Said body preferably has a pair of depending lugs l by -which it may be pivoted upon a suitable support.'v Y

`The' support is preferably such as indicated in Figs. 1 and 2, and consists of a baseplate 2 having a lug 2SL on its upper side adapted to fit between the-lugs 1b on the lower side ofthe body 1, andhaving a Vthreaded shank v2C which is adapted to extend through a suitable opening in the dash board'or cowl C, and be secured thereto by a nut and washer: of any suitableV kind, such as shown at 2e. Anopening 2t extends axially through the' shank 2c (as indicated in dotted lines Yin Fig. 3), and up through the base and lug-21 passing to one. side of the pin 2g by which the lugs 1b of the casing 1 are pivoted to .lug 2.aL of the support.

The casing 1 has a slot or opening lc in its lower side between the lugs 1b so that an insulated conductor W may be led up through the opening 2f in the ysupport and through the passage 1c into the `body as shownv and be connected to a pin 3 therevin as hereinafter explained. V l

-The casing l can be adjusted at any desired angle relative to the support 2, and locked when adjusted by means of a socketscrew-1g tapped throuofh a suitableopening in one of the lugs 1b 1n position to engage the side edge of lug 2b as indicated in Fig. l. While I 'prefer to use the support 2 as shown and described any other Suitable support may be used.

In the example shown a pin-3 preferably made of non-conducting material kis slidably fitted in the socket 1a in the casing, and is normally partially projected by means of a spring 3a in the socket. The inner yend of the conductor W may be securedV to thepin' 3 in any suitable manner, preferably by means of a screw 3, which `forms. an electric connection with the wire, see Fig. L1, the screw 3b being tapped through a threaded opening in the outer end of the plug. The pin 3'is yieldingly pressed forward by the spring 3a, and the screw v3" in this instance forms an electrical contact member adapted to engagewith an opposed contact member on the electric lamp holder withinA the cas- Y ing 1. Y j Y As shown I preferably use an electric lamp L havingA a socket kengaging' member L of standard construction. The lamp is mounted in a removable holder adapted to be readily inserted in or removed from the casing.

The holder 4 comprises a cylindrical socket member 4a, a member 4g adapted to close the open end of the casing, and a connecting member 4e. The holder 4 has two slots 4b for engagement with the lamp shank L. To one end of the member la is secured a hollow member 5 (see Fig. 3) preferably of non-conducting material, which extends through an axial opening in the end of member 4 and has a flange 5a engaging the inner end wall of member lla. The outer part of member 5 is externally threaded and engaged by nuts 5b which fasten the member 5 to the member 4f, as shown in Fig. 3. Y

In the outer end of member 5 is an axial pin 5 adapted to make electrical contact with the screw 3b to which the conductor N is attached when the light holder is inserted into the casing. The member 5 as shown has a socket in its inner end in which is slidably engaged a hollow contact piece 6 which is held normally projected by a spring 6a confined in the contact piece 6 and in the socket in the member 5, the spring making electrical contact between the pin 5n and the contact piece 6. This piece 6 normally projects in such position that when the lamp shank L is inserted into socket ta and engaged with the slots 4b the usual contact point in the lamp shank makes electric contact with the piece 6, which is yieldingly held in contact therewith by the spring 6a. Thus when the holder and lamp are in the position shown in Fig. 3 an electric circuit is established from the conductor W to and through the lamp.

The socket member 41a is connected by a. bar 4:9 with the casing closing member 4g, the members la and 4g being spaced apart suificiently to enable thelamp L to be inserted into engagement with part Ala, or removed therefrom, in the space between the members la and 4g. Part 4g has a reduced ange 4f on its inner end which is adapted to fit into the outer end of the casing or body 1 (see Figs. l and 3), part fig being preferably slightly greater in external diameter than the forward end of the casing 1. The part 4g also forms a stop to limit the inward movement of the lamp support and preferably position it in the casing. Said part 4g is preferably cylindric and a glass or jewel is secured therein as shown.

When the lamp supporting member is inserted into the casing the ange lg abuts against the outer end of the casing and the lamp is in proper position and the proper electric connections are made between the lamp and the source of electricity through wire W so that the lamp will be lighted when the current is turned on.

The lamp support may be detachably retained in the casing by any suitable means. I preferably employ a screw as shown at 7 tapped through the wall of the casing near the front end thereof and engaging the member 4J, and fastening the bulb holder securely in position.

It will be seen from the foregoing that the light is adjustable on the cowl; it can be readily connected with the battery or generator of the automobile; the removable lamp holder renders it very easy to renew or replace the lamp, or to repair any interior part or connections which may be broken, and the light is compact, simple, and attractive in appearance.
