ADJUSTABL SUPPORT FOR SIGNAL-LAMPS.

To a/ZZ whom it may concern,.-

Beit known that I, ALEXANDER II. HAND- LAN, Jr., a citizen of the United States of America, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Adjustable Supports for Signal-Lamps, of which the following is a full, clear, and eXact description, reference being had to thel accom anying drawings, forming part of this speci cation.

My invention relates to an adjustable support for signal lamps used upon railway cars, the invention having for its object to provide a su port for-such lamps that will permit of the amp being lifted from its lower position, then adjusted in a lateral direction relative to the part of the car to which the su port is applied, whereby the lamp may be disposed at the required angle or focus and then returned t0 its lower position.

My adjustable support is designed to take the place of rigid lamp sup orting brackets heretofore in use and whicli are ordinarily fitted to sockets a plied to railway cars. In view of the fact that the surfaces of the'cars to which the bracket receiving sockets may be applied are irregular, it is difficult to so position the brackets and support the lamps at the required angles of foci, whereas such positioning of the parts is readily securable Figure I is a side elevation of my support with a lamp ap lied thereto. Fig. II is an enlarged vertica section taken through the support. Fig. III is a horizontal section taken on line III-III, Fig. II. Fig. IV is a view similar to Fig. II, illustrating a modification. Fig. V is a view similar to Fig. III,

of the modification shown in Fig. IV. 4o

A designates a signal lamp and B the wall of a car to which the lamp is adapted to be applied.

1 designates a socket that is'secured to the car wall and 2 is a bracket arm which is seated in said socket. This bracket arm is provided with a horizontal wing 3 in the edge amp shell. 8 is a pivot post that is vertically ositioned in the arms 5 and-6 and to whic the bracket arm 2 is loosely iitted for the purpose of permitting lateral swinging motion of Speccation of Letters Patent.

Application filed November 12, 1906. Serial No. 343,038.

Patented June 18, 1907.

' the arms 5 and 6 and the lamp when th pivot post is moved upward with the arms 5 and 6.

9 is a depending locking pin seated in the upper lam carried arm 5 and projecting beneath sai arm, in order that it may enter into either of the series of openings 4 in the wing 3 of the bracket 2 for the purpose of holdingl the lamp carried arms from movement relative to the bracket arm 2.

10 is a spring located between the lower lamp carried arm 6 and the bracket arm 2. This spring preferably surrounds the pivot post 8 and seats in a cavity in the bracket arm as seen most clearly in Fig. II. The spring serves to exert downward pressure upon said lower lamp carried arm with aresult of holding the locking pin Qin the pocket of the bracket arm wing 3, in which -it has been seated, thereby preventing accidental 'dislodgment of said pin from said pocket due to the jarring of the lamp while the car that carries the lamp is in motion.

When it is desired to adjust the lamp in a lateral direction itis only necessary to lift the lamp and its arms 5 and 6 relative to the ing pin is permitted to enter into another of the pockets 4 of the bracket wing 3.

In Figs. IV and V, I have lllustrated a modification in which the bracket arm wing 3 is shown provided with a segmental series of openings in the form of pin-holes 4 in-lieu of the open openings 4 to receive the locking pin 9. In this construction the spring 10 is dispensed with. The remainingparts of the sup ort are similar to those previously described and the action thereofis the same as in the first recited construction, with the eX- ception that no means is provided to prevent dis lacement of the locking pin 9 from the brac iet arm wing, due to jarring of the celtio which my lamp support may be app ie I claim f Y 1. A supporting bracket for signal lamps comprising a bracket arm having a horizontal wing formed with a segmental series of openings, a bracket plate having upper and ICO IIO

ro upper arm is seated upon the wing and to bel necting the upper and lower arms and secured thereto, and a depending pin secured to the upper arm and adapted to engage one of the series of openings in the wing when the released from the opening when the upper arm is raised from the wing to enable the lamp to be moved laterally.

2. A supporting bracket for signal lamps comprisin a bracket arm having a horizontal wing ormed with a segmental series of openings7 a bracket plate having upper and lower arms spaced apart a greater distance than the height of the bracket arm and between which the bracket arm with -its wing projects, a vertical pivot post adapted to slide vertically in the bracket arm and connecting the upper andlower arms and secured thereto, a spring coiled around the ivot post between the bracket arm and the ower arm, and a depending pin secured to the upper arm and adapted to engage one of the series of openings m the wing when the upper arm is seated upon the wing and to be released trom the opening when the upper arm is raised from the wing to enable the lamp to be moved laterally.
