Aug. 13, 1935. c. c. LAMB SIGNALING DEVICE Filed Sept. 18, 1954 Patented Aug. 13, 1935 UNITED STATES PATENT OFFICE 10 Claims.

This invention relates to the class of signal devices and pertains particularly to a combined direction indicating signal and light projector.

'I'he primary object of the present invention is to provide a novel unit having a transparent or translucent body constituting a housing for light signals, and a light transmitting portion which may constitute a light projector such as a spotlight.

Another object of the invention is to provide a combined spotlight and direction indicating signal in which the body portion of the light is in the form of a hoodformed of transparent or translucent material through which lighted signal elements may be shown.

The invention broadly contemplates the provision of a body which is preferably of parabolic formation and which is formed of light transmitting or translucent material in which is housed two signal lights which when energized make apparent an indicating symbol carried by or forming a part of the body. The larger end of the body houses a light reflector over which a lens is positioned and which houses an incandescent lamp which when energized provides a spotlight.

'Ihe invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specication, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modied so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:-

Figure 1 is a view in elevation of the signal structure. Figure 2 is a longitudinal sectional view through the device embodying the present invention.

Figure 3 is a sectional view taken upon the line 3-3 of Figure 2.

Referring to the drawing, the numeral I indicates generally the housing of the present signal which, while shown as being of circular cross section or in the general form of the casing of a parabolic reector, may be of polygonal cross sectional design and of conical or pyramidal form, if desired.

'Ihe illustrated and preferred form of the body I is in the form of a hood or bell. which is divided to form the outer and inner sections 2 and 3, respectively, the outer section being closed at one end, as shown, and having an axial passage 4 for the purpose hereinafter described.

The body I has extended thereinto or is tted over in the assembling of the device, the substantially U-shaped frame 5, the inner wall of the body being provided with a channel i in which this frame engages. The frame 5 has the forward and divergently related ends thereod.' formed integral with a concave head plate 'l at the periphery of which a ange 8 is formed.

Carried by the ange 8 of the frame 5 is a collar band 9 which has an inwardly extending flange I0, which rests upon the flange 8, as illustrated in Figure 2, and the edge of the mouth of the bell-shaped housing I abuts this ange I and is maintained in rm contact therewith by the bolt Il which is extended from the inside of the frame through a suitable aperture therein and through the aperture 4 of the bell. This bolt at its outer end passes through a handle or knob I2 with which the nut I3 contacts, so that it will be readily seen that the knob and frame are drawn together so as to rmly secure the housing I therebetween and to draw the flange 8 of the frame head into rm contact with the collar flange I0 which bears against the edge of the body.

Disposed within the collar band 9 is a reflector I4, the peripheral portion of which rests against the forward edge of the band and has disposed thereagainst the lens I5 which is held in position with the reector I4 by the split annulus I5.

The band 9 has formed integrally therewith the tubular extension I1 which constitutes a trunnion which is oscillatably held in the bearing I8 which is formed transversely of one end of the post I9. This post I9 is in turn supported in a bearing 20 which is carried by any suitable supporting xture, such as an arm 2l which may be attached, as desired, to any part of the vehicle upon which the signal structure is to be mounted.

At approximately the transverse center of the frame 5, there is disposed a reiiector 22 which is secured to the frame and which is of a to snugly position within the housing I at the point of joinder between the two sections thereof. l The housing I is thus divided into two chambers in each of which an incandescent bulb 23 is located.

The frame 5 is of triangular cross sectional, design, as illustrated, in Figure 3, and at suitable points, it is drawn inwardly to form the electric light bulb sockets 24 in each of which a bulb or lamp 23 is mounted. Adjacent each of the diameter sockets 2l, the sides of the frame 5 are cut to form tongues which are bent in into the overlapping relation shown in Figure 3, and which have secured therebetween an insulation lining 26 through the center of which a resilient metallic strip 21 passes. Each of these metallic strips 21 has an end extended into the adjacent socket 24 to a point where one terminal of an inserted base of an incandescent lamp will come into Contact therewith While at its other end, the strip carries a screw or other suitable means 28 for effecting the connection of an electric wire' 29 therewith. l

A similar strip, which is indicated by the numeral 30, is secured in insulated relation to the head 1 of the frame and has the electric wire 3l connected to one end and its other end disposed behind the central portion of the reflector ill, so as to be engaged by the center contact of electric light bulb 32 when the same is introduced into the socket sleeve 33. The wires 29 and 3| are carried olf through the tube trunnion il to the necessary controlling switches and source of potential.

While the bell-like body i has been illustrated as formed in two sections, it is, of course, obvious that it may be cast as a single piece, if desired. This body, whether in two pieces or one, may be formed of transparent material or of a translucent material and in a plane with each of the chambers into which it is divided by the partition reflector 22, it may be pressed to form or have otherwise suitably applied thereto a signaling symbol such, for example, as the arrows 3L These symbols may be formed to stand out so that the material of the housing is thicker where they are formed, or this portion may be made thinner by pressing the material in and by giving to each of the sections a distinctive color, the symbol area, being of a different thickness from the remainder of the body, will stand out distinctly when the enclosed lamps are lighted. If desired, the body l may be made of uncolored material and the bulbs 23 may be of contrasting colors such, for example, as red and green, with the surfaces of the reflector 22 colored to conform to the color of the adjacent bulbs. By this means, when either bulb is lighted, the section of the casing immediately surrounding it will be given the color of the illuminated lamp.

From the foregoing, it will be readily apparent that the herein described device is of a novel, efcient and compact design, and may be mounted in any one of a number of locations upon a motor vehicle for manipulation in any desired manner.
