HEADLIGHT-OPERATING MECHANISM.
SPECIFICATION forming part of Letters Patent No. 712,433, dated October 28, 1902.
A Application filed August 8, 1902. Serial No. 118,894. (No model.)
To aZZ whom, it may concern:
Be it known that I, GEORGE F. CHAPMAN,
of Marlboro, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Headlight- Operating Mechanism, of which the following is a specification.
This invention relates to means for connecting a pivoted headlight on a street-car or other vehicle with a portion of the runninggear of said vehicle, so that when the vehicle is running on a straight portion of track or roadway the rays from the headlight will be directed along a path in line with the longia car-body and a truck-frame which will be compact and also out of the way of other appliances which may be located beneath the car. i
To these ends the invention consists in the construction and combination of parts, substantially as hereinafter described and claimed.
In the drawings, Figure 1 represents a side elevation of part of the front portion of a street-cantogether with the front truckframe, and showing one embodiment of mypresent invention. Fig. 2 represents a plan view of the parts shown in Fig. 1, the corresponding portion of the car-body being shown in dotted lines. Fig. 3 represents a detail plan view of a portion of the connection with the truck-frame. Fig. 4 represents a detail view, partly in section, of the complete connections shown in Fig. 1 between the bolster Fig. 5 repre-I ;naled in the ears or bearingscc.
the bolster and an arm on the rock-shaft. Fig. 9 represents a detail plan of the connections shown in Fig. 1. Fig. 10 represents a view similar to Figs. 1 and 6, but representing another modification of the connections. Fig. 11 represents a plan View of the connections shown in Fig. 10. Fig. 12 represents an enlarged detail side elevation of a part of theconneetions shown in Fig. 9. Fig. 13 rep- 6o resents a section on the line 13 13 of Fig. 12 looking in the direction of the arrow.
In the drawings, a represents a portion of the body of a street-car, and or represents a portion of the front fender or dasher of the car, or a may he considered as representing the front wall of a vestibule at one end of the car-body.
1) represents an independently movable part below the body a, said part being in this instance the bolster portion of the truckframe, said portion being pivotally connected at b with the body a. l
0 represents a holder which is affixed to the part a of the car-body and is here shown as a bracket having two ears or bearings c c.
(1 represents the headlight, which is secured to a vertical stud or trunnion d, jour- The relative arrangementof the headlight d, shaft or trunnion d, and the car-body is such that the headlight can occupya central position, so as to direct its rays ahead in line with the longitudinal center'of the body or can be turned or deflected to direct its rays to either side of 8 5 said longitudinal center. In the embodiment of my invention now under consideration the headlight is normally held in its central position and isautomatically deflected from said position by changes in the position of the bolster I) through connections between the headlight'and the bolster. The connections illustrated in Figs. 1 to 5, inclusive, comprise an arm e, rigidly connected with and projecting forward from a partof the 5 truck, as the bolsterb. A bifurcatedlug fis pivoted to the arm e at f and is provided with a short rod g, projecting forward therefrom and entering a sleeve h, the forward end of which sleeve is provided with the ball '1 co member 41 of a ball-and-socket joint. The
socket member is of said joint is suspended by a crank-arm Z, depending from a rockshaft m, suitablymounted in bearings m beneath the car-body. A shaft n, mounted in a suitable bearing at the bottom of the front betweeh the lugf and the arm 6, together with the sliding connection between the rod 9 and the sleeve 71., will provide for a rocking movement of the truck-frame relatively to the car and for the difference between the direction of movement of the arm a, which swings horizontally on a vertical axis, and the crank-arm Z, which swings on a horizontal axis.
In the modification illustrated in Figs. 6, 7,
8, and 9 the parts and their connections remain substantially the same, excepting those between the rock-shaftmand the forwardlyprojecting arm e of the bolster. In said figures the forward end of the arm 6 is provided with a rigid upright stud 10, having a lateral pin 19. Said pin enters a vertical slot q, formed in the side of a socket q. From the top of said socket an arm or rod (1 extends forward and through a vertical slot 7" in an adjustable crank-arm r, secured on the rockshaft m. The connections between the rockshaft m and the vertical stud d of the headlight are substantially the same as in Fig. 1 and hereinbefore described. The sliding con nection between the studp and the socket q of the arm g provides for the same relative movements as that for which the pivot f is employed in Fig. 1. The pin p, projecting from the stud 19 through the slot q of the socket, causes the arm g to vibrate'laterally with the rigid arm 6 of the truck-frame, and said arm g through the arm 11, which is secured on the rock-shaft m, causes the latter to rock and through the shaft n turns the headlight.
In Figs. 10 to 13, inclusive, the rear end of the rock-shaft m has secured to it a crankarm 8, the wrist-pin s of which enters between the arms of a fork t, which latter is swiveled to the front end of the arm 6. In this form the height of the fork is such that difierences in elevation between the truckframe and car-body are compensated for.
In each form the device at the rear end of the rock-shaft m is essentially a crank, while the intermediate member between it and the arm 6 of the truck-frame is a compensating one.
In another application for Letters Patent for improvement in devices for operating headlights, filed June 13, 1902, Serial No. 111,559, I have claimed the combination, with the truck of a car, a body thereon, and a headlight, of suitable connections between the headlight and the truck for turning said headlight and means interposed in said connections for automatically varying their length in unison with the independent movements of the car-body and car-truck.
The present invention is embodied in a combination of elements constituting relatively compact, durable, and simple connections between the headlight and truck. Important elements of said combination are as follows: lirst, the arm e, projecting forward from the truck-frame and movable laterally and horizontally by the turning movements of the truck-frame; secondly, the substantially horizontal rock-shaft between said arm and the shaft of the headlight, the rock-shaft having a crank which oscillates in a vertical plane, means for communicating motion from the arm to the crank and rock-shaft, so that the latter is turned in its bearings and caused to correspondingly turn the headlight-supporting shaft by horizontal movements of the arm, said means having provisions, therefore, for compensating for the difference between the direction of movement of the arm and the direction of movement of the rock-shaft. The combination as a whole also has provisions for converting lateral movements of the arm into turning movements of the headlight.
I claim 1. The combination with a truck-frame and a body, of a headlight mechanism comprising an arm projecting forward from the central portion of the truck-frame and movable laterally by the turning movements of the truckframe, a headlight pivotally mounted on the forward portion of the body, and self-adjusting connections between the arm and headlight, whereby lateral movements of the arm are caused to impart corresponding movements to the headlight.
2. The combination with a truck-frame and a body, of a headlight mechanism comprising an arm projecting forward from the central portion of the truck-frame and movable laterally thereby, a headlight pivotally mounted on the forward portion of the body, and connections between said arm and body having provisions for converting lateral movements of the arm into turning movements of the headlight.
3. The combination with a truck-frame and a body, of a headlight mechanism comprising an arm projecting forward from the central portion of the truck-frame and movable laterally thereby, a headlight pivotally mounted on the forward portion of the body, a substantially horizontal rock-shaft journaled below the body and extending lengthwise thereof, connections between the rear portion of the rock-shaft and the said arm, through which the shaft is rocked by lateral movements of the arm, and connections between the forward portion of the rock-shaft and-the headlight, through which the headlight is turned by the movements of the rock-shaft.
4. "lhe combination with a truck-frame and a body, of a headlight mechanism comprising an arm projecting. forward from the central portion of the truck-frameand movable laterally thereby, a headlight pivotally mounted on the forward portion of the body, a rockshaft jonrnaled below the body and extending lengthwise thereof, flexible connections between the forward portion of the rock-shaft and the headlight, and flexible connections between the rear portion of the rock-shaft and the arm, the last-mentioned connections having provisions for compensating for the difference between the direction of movement of the arm and the direction of movement of the rock-shaft.
.5. The combination with a truck-frame and a body, of aheadlight mechanism comprising an arm projecting forward from the central portion of the truck-frame and movable laterally thereby, a headlight pivotally mounted on the forward portion of the body, a rockshaft extending lengthwise of the body, connections between the forward portion of the rock-shaft and. the headlight, and compens sating connections between the rear portion of the rock-shaft and the said arm, the said compensating connections includinga crank member engaged with the rock-shaft, and an intermediate compensating member between the crank member and the arm.
