UNITED STATES MARK NOSAL, OF BARNESVILLE, MINNESOTA.
w TRAFFIC SIGNAL.
Application filed January 2, 1923. Serial No. 610,322.
To all who! if may concern:
Be it known that I MARK NosAL, a citizen of the llnited States, residing at Barnesville in the county of Clay and State of Minnesota; have invented new and useful Improvements in Traffic Signals, of which the following is a specification.
This invention relates to a head lamp for motor vehicles, the general object of the invention being to provide means for passing a shield over the bulb of the lamp when it is desired to decrease the amount of light from the same.
Another object of the invention is to provide means whereby the dimming effect can be varied. I
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a front view of a motor vehicle showing the invention in use.
Figure 2 is an elevation with parts in section showing the operating means for the invention.
Figure 3 is a longitudinal sectional view through one of the lamps with the invention attached thereto.
Figure 4 is a plan view of Figure 3.
Figure 5 is a section on line. 5-5 of Figure 4.
Figure '6 is a detail sectional view of the operating means. i
In these views 1 indicates the lamps of the vehicle, each of which is equipped with the usual reflector 2 and the lens, 3, the bulb of the lamp being shown at 4. In carrying out my invention I provide a housing 5 at the rear of each lamp which is preferably hinged to the lamp, as shown at 6. This housing slid-ably supports a cylinder 7 preferably made of glass, and has its front part passing through a central opening made in the reflector and which vhas a flange 8 for engaging a part of the reflector when the cylinder is in retracted position. This cylinder is arranged to surround the bulb 4 when projected forward into the position to hold the handle with the cylinders in shown in dotted lines in Figure 3 so as to dim the light by filtering the rays of light striking the reflector. This cylinder is prefthe rays of light to escape. In this Way the dimming effect can bedecreased or increased as desired. The rear part of the cylinder is reduced and is provided with a groove in which is located a ring 9 to which one end of a rod 10 is connected. This rod is slidably mounted in the housing 5 and is connected by a pin and slot connection with an arm 11 which is located on a shaft 12 mounted to rotate in the housing. This shaft 12 is connected by the arm 13 with a link 14: which has its other end connected with an arm 15 which is secured to a shaft 16 which has its ends journaled in brackets 17 connected with the lamps so that the two cylinders will be moved in unison when the shaft 16 is rocked. This shaft is rocked by means of the rod 17 having one end connected with the arm 18 on the shaft 16 and its other end connected with the handle 19 which passes through a hole in the dash of the vehicle. The handle is provided with notches 20 for engaging a plate 21 on the dash, these notches serving as either a retracted or projected position. A spring plunger 22 serves to keep the notches in engagement with the plate.
The bulbs 4 and their sockets are adj ustcd to get the desired focus by means of the screw rod 23 connected with the socket and passing through the rear of the housing where its screw threaded partengages the nuts 24. y
From the above it will be seen that by-v either pushing in or pulling out the handle 19 the shaft 16 will be rocked to cause the arms and shafts to move the cylinders 7 into projected or retracted positions as in- A dicated in full and dotted lines in Figure 3. Then the cylinders are in projected positions they wil act to filter the rays of light passing from the bulbs upon the reflectors and thus reduce the volume of light thrown forwardly by the lamp. This will prevent blinding of drivers of vehicles approaching the vehicle carrying the invention.
It is thought from the foregoin description that the advantages and nove features of my invention will. be readily apparent.
in; i
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
What I claim is 1-- 1. The combination with an automobile lamp, and a longitudinally movable translucent cylinder adapted to encircle the lamp bulb, of a manually operable rock shaft, an
1 arm associated therewith, an element slidably mounted in the lamp casing, a rock shaft journaled in the lamp casing and operatively connected with the crank arm. and an operative connection between the slidable element and last mentioned rock shaft,
and a collar carried by the slidable element and embracing one end of the translucent cylinder.
2. The combination with an automobile headlight, and a dimming element longitudinally movable over the light therein, a rock shaft journaled in the lamp casing, a crank arm fixed thereto, a stem slidably mounted in the casing and having operative connection with the crank arm, an operative connection between the stem and dimmer,
and manually operable means for rocking the rock shaft to move the dimer forwardly or rearwardly over the light.
In testimony whereof I affix my signature.
MARK NOSAL.
