- DASH LAMP.

. Ap'plication filed September 20, 1924., Serial n rmaesaf This invention relates particularly to a dash lamp which can be readilymounted on an instrument plate carried by an automobile-dash. I

The primary object is to provide animproved dash lamp of this characterwvhich. can be readily applied, which is thoroughly adapted to its purpose and which can be cheaply manufactured. j The invention is illustrated in its preferred embodiment I in the accompanying drawings, in which I Flgure 1 represents a broken front ere; vatlonal view ofan automobile-dashupon which is mounted an instrument-platehaving applied thereto the improved dash lamp; Fig. 2, a broken rear elevational view of the same; Flg. 3, a vertical sectional view taken as indicated at hne 3 of Flg. 1;

Fig. 4, a vertical sectional view, on an enlarged scale; taken as indicated at line 4 of Fig. 1; Fig. 5, a broken planview of the dash lamp bracket; and Fig. 6, a rear ele,-.

vational View of the dash lamp device.

In the illustration given, A represents a sheet metal dash of an automobile; B, an instrument-plate removably mounted thereon, which carries aswitch device B and an ammeter B and C, the improved dash lamp mounted on the instrument-plate.

The dash A and instrument-plate B are of well-known construction. The dash is provided centrally with a large opening, or

slot, 1, whose upper wall is designated 1 The instrument-plate B is detachably secured to the dash by screws 2, and forms a covering for the opening 1. v

The instrument-plate B is provided peripherally with a rearwardly turned flange 3 which bears against the front surface of the dash A. i

The dash lamp C comprises a plate-clamping bracket C and an electric connector mounted thereon. I

The bracket C" comprises a cup-shaped base 4 which bears against the front surface of the upper portion of the instrumentplate B, and a clamping arm 4 which preferably is formed integrally with the upper portion of the base member 4. The bracket preferably is formed from sheet metal having one portion cupped to form the base 4 and having a web 4 which is adapted to extend over the upper flange of the instrument-plate B. The arm 4'? has relatively broad, portion 4,

In forming the bracket, the arm 4 tongue 4 are rear- 7 wardly turned lugs-4 which from which depends the central clamping tongue4 which hasits lower extremity bent forwardly to, form an" inclined flange 4 which engages therearbent sufficiently toward the base 4 to cause] the device-toclamp when it is appliedthereto. 1

The arm 4*? is providedwith a large cen tral perforationfi, and theweb portion 4 of the bracketv is provided. with a slot 6 which intercepts the opening 5. Thus, there.

he instrument-plate is provided a channel for the passage of the,

electric conductor 6 y x The electric connector C is shown as comprising a sleeve 7 ,in which is mounted a longitudinally movableinsulation plug 8,

equippedwith a central contact 9 whichlis,

in electrical connection with the conductor 6 The outer end of the sleeve7 isprovided with a socket 7 for the lamp bulb 10.

This socket may have the usual bayonetv slots for connection with the'lamp bulb, or threaded connection may be employed. if desired. '4

Upon the front end. of the sleeve 7 is mounted the usual hood-reflector, 11. In the, illu'stration given. a'spring 12 is interposed between the movable plug 8 and the base of the lamp. The plug may be shifted longitudinally in the sleeve 7 to make and break the contact by means of a handle, or pin, 13, which works in a suitable cam slot 13 with which the sleeve 7 is provided.

The sleeve 7 preferably is provided near its inner end with a flange, or head, 7 and p the inner extremity of the sleeve extends through a perforation in the base 4 and is spun outwardly to provide a retaining flange 7. Thus, the sleeve 7 is securely fastened to the hollow base portion 4 of the bracket.

The central contact 9 of the plug 8 preferably is a spring projected contact mounted in a bushing 9 whose rear end is fitted with a plug 9 having a bore for receiving the wire of the conductor 6 The Wire is es cured in the bore by means of a screw 14.

V T 118, the bracket of t .ingly The web portion 6 of the bracket C preferably has themetal struck outwardly to provide reinforcing ribs 15.

7 It will be understood that the instrumentplate B may be removed from the dash, and that the dash lamp may be applied to the instrument-plate by slipping it over the upper edge of the central portion of the plate, the s ring arm yielding to permit this action. W en the plate is reapplied to the dash, the lugs 1? are caused to engage the u per wall of the opening in the dash.

e dash lamp clampengages the upper portion of the instrument-plate and has its clamping arm clamped between the instrument-plate and the dash, o p I The foregoing detailed description has been given for clearness of understanding only, and no unnecessary 1imitations should be understood therefrom, but the appended claims should be cc'instrued as broadly as permissible in view ofthe prior art.

a bear against the rear surface ment late, said arm having a rearwardly What 'I regard'asnew, and desire to secure by Letters Patent, is:

l. Aidash lamp device comprising an electric "connector, and a supporting bracket adapted tov clamp on an instrument plate coinprising a base adapted to bear on the frontsurface of the plate and upon which said connector is mounted, and a spring arm connected with the upper portion of said base and having an extremity adapted to of the instruex'ten ing flug 'adapted to-e'ng'age the upper wall of a slot'in the dash. v

2. A dash 'la'inp de'vi'ce comprisingan electric connector, and a sheet-metal bracket having a hollow base portion adapted to bear against the frontsur'face of an instrument-plate and carrying said connector and having a web adaptedto extend over the upper edge of aninstrurnent-plate and an arm adapted todepend back of the plate,

instrument-plate and the dash.

4;. In combination, a metal dash provided with an opening, an instrument-plate detachably secured to said dash and covering said opening, and a dash lamp device com-iv prising an electric connector and a supporting bracket, said bracket having a base portion upon which the connector ismounted and which bears against the front 'surface of the upper portionof the instrumentplate and said bracket having a web portion extending over the upper edge of the instrument plate and an arm dependingfrom said web portion, said arm having a portioneng'agl'n'g the rear surface of the instrument-plate and having a portion en-' gaging'the wall of the opening of said dash.

5. A dash lamp device comprising an electric connector, and a supporting bracket adapted to clamp "on anins'trument plate and embrace the upper portion onlyjof said plate and comprising a base adapted to bear on the upper portion of the front surface of the plate land upon which said connectoris mounted, and a v spring arm connected with the upper portion of said base and havingfan e xtr ernit'yadapted to bear against the rear surface of the instrument plate at a point'dist'ant from the upper edge of the plate.
