9 Claims.
This invention relates to a class of electric lamps to some extent used on automobiles and similar motor vehicles wherein the lamp is pivotally mounted to oscillate horizontally or vertically or under a compound horizontal and vertical movement to light up the road and particularly the edges and shoulders of the road at night; the oscillating movement being effected by a motor under the control of the driver.
The primary purpose of my improved lamp is to serve as what 1 term a passing lamp, to signal, by a horizontally oscillating light beam, to a car ahead that the driver desires to pass. The main object of the invention has been to provide a very simple, practical and inexpensive lamp of this type.
Other objects and attendant advantages of the invention will be apparent to persons familiar with lamps of this character from the following detailed description taken in connection with the accompanying drawings in which I have shown an illustrative embodiment of the invention and wherein:
Fig. 1 is a top plan view with the hood or casing in horizontal section.
Fig. 2 is a side elevation, with the hood or casing in vertical section on the line 2--2 of Fig. 1, and broken 01f at the front.
Fig. 3 is a sectional detail showing the means for pivoting the reflector in the arms of the frame.
Fig. 4 is a transverse section taken on the offset line 44 of Fig. 2.
Fig. 5 is a fragmentary side elevation illustrating a modification.
Fig. 6 is a transverse section on the line 5-6 of Fig. 5.
Referring to the drawings, in designates a metal hood or casing preferably of the shape illustrated in Figs. 1 and 2, which contains the lamp, its mounting frame, motor, and motoractuated oscillating means. The forward open end of the hood In is closed by a glass lens ll mounted in a suitable rim l2 which fits over an inwardly offset rim ID of the hood and is removably locked thereto by pins 13 engaged with holes in the rim l locked against displacement by one or more spring keepers Id.
The supporting frame for the lamp and motor is preferably a casting having a flat base plate l and a pair of upper and lower forwardly extending arms [6 and I1 respectively. The inner portion ll of the lower arm 11 is widened and concaved on its lower side to fit the casing l0, and provided with a pair of tapped holes 18 to receive screws l9, the said screws also serving to mount the casing H) on a seat or saddle 28 carried by an 'upright post 2| that may be mounted in any '3- which extends the shank or stem 23 of a bowl shaped lamp reflector 24; the hollow shank 23 also supporting a lamp socket 25, in the forward end of which is mounted the electric lamp bulb 26. Fig. 3 illustrates the preferred means of mounting and pivoting the yoke and reflector in the arms of the frame, whereby it will be seen that the reflector 24 is formed with a peripheral flange 21 that is soldered at 28 to the ends of the arms of yoke 22; and the frame arms I6 and I! and the arms of the yoke 22 have registering holes 29 and 30 respectively, to receive a pivot pin 3| formed with an integral spacing washer 32 that, when the parts are assembled, prevents the escape of the pin.
Attached to the rear side of the base 15 of the frame as by screws 33 is the frame base 34 of a small electric motor, preferably of the oscillating type such as is used to actuate windshield wipers, although a rotary motor may be employed. This motor is not shown in detail as it is a known commercial article, and the main portion of the frame, the field, armature, etc., are covered by a cap 35 attached by screws 36. Through speed reducing gearing (not shown) the motor oscillates a forwardly projecting shaft 31 which extends through a hole in the frame base 15 and is formed with an offset or crank arm 37', which latter, as best shown in Fig. 4, lies within a vertical slot 38 formed in a lamp and reflector carrying yoke 22, as a result of which, when the motor is energized, the oscillations of the shaft 31 transmit horizontal oscillations to the reflector 24 and lamp 26 carried by the yoke 22, so that, if the lamp is lighted, a horizontal beam of light is thrown back and forth from side to side of the road. It is obvious that if the motor transmits a continuous rotary movement to the shaft 31, the result will be the same, the slot 38 being of sufiicient length to accommodate the maximum high and low positions of the crank 3'1. The portion of yoke 22 engaged by the crank 31' forms in effect a reflector oscillating arm that extends parallel with the pivotaxis of the reflector.
Figs. 5 and 6 illustrate a modification, wherein the yoke 22 is dispensed with, and the reflector 24 is formed with a peripheral rim or band 39 that is directly pivoted to and between the yoke arms I 6 and H by the pivot pins 3|; and mounted on and soldered to the hollow reflector shank or stem i is a wire coil 4| formed with a tangential integral loop 42 lying parallel with the pivot axis of the reflector that receives and cooperates with the crank 31' of the shaft 31 in the same Way and to the same effect as the slot 38 of the yoke 22 previously described.
It is to be understood that in practice the motor and lamp circuit is wired through the usual generator to the dash of the car and is equipped at the dash with a normally open switch that may be closed by the driver as he approaches a vehicle which he wishes to pass, the waving light beam constituting a signal to the car ahead to allow room for passing.
I am aware that mechanically oscillated lamps for automobiles are broadly known; but such lamps have heretofore been unduly complicated and expensive. It will be seen that my improved lamp is of very simple and relatively inexpensive construction, requiring no gears (except the usual speed reducing gears associated with the motor) and certain and reliable in action. The structural details herein shown and described may, obviously, be varied within the purview and scope of the appended claims.
