SUPPORTING BRACKET Fen RAILWAY SIGNALS.

Application fi1ed;;March 26, 1926. SerialNo. 97,514".

This invention relates to the supporting brackets used on railway signals and 1t particularly relates to abracket ior supporting a lampor light signal at the top or a mast and which requires adjustment in different planes. The objects of the invent on are to provide a bracket of this type which canbe easily adjusted to d'ellect the beam 0t light from the signal in a predetermined direction and which is universally adapted to diiterent conditions in the construction of signals. I The present form of bracket is adjustably clamped against the signal mast and can be moved up and down or rotated on the mast. The part that is clamped to the mast terminates in a vertical disc and pivotally clamped to this disc is another matchcddisc at the extremity ot the supporting arm. This arm therefore rotatable about the horizontal pivot which supports it. I The supporting arm has a downward oliset and terminates in a horizontal disc upon which the lamp or signal device is pivotally mounted. This enables the lamp to be rorated in a horizontal plane relative to the arm and at the same time the arm may be rotated on its pivot causin the lamp to rotate on a vertical plane. lhus, the lamp and the beam of light therefrom can be brackets of this character. In View of the fa. however, that these brackets are located at the top of a signal mast, are accessible only on a ladder and have to be adjusted under severe weather conditions, the present in- ;vention has a number of advantages over the hall and socket type. In the latter both hands are required to make the adjustment. In the present invention one of the pivot bolts is released and adjustment in one plane is made as required and the parts secured in this position, then the other pivot is released and adjustment in the other plane is correspondingly made. he made by one hand. The parts are held in alignment by the large engagingsuriaces as the adjustn'icnt is made, and'there is no tendency for gravity to change the adjustment after it has been set up.

The novelty of this invention is more particularly pointed out in the claim and the construction will be particularly understood from the following specification and the ac- These adjustments can companying drawings, in which, Fig. 1, is at! side elevation of a supporting bracket embodying my invention; Fig.v 2' is a plan View corresponding to Fig. 1, Fi-g; 3 shows one style of railway signaljwith which this in vention may be used and Fig. i is a planx:

The signal mast is indicated by 11- a-ndjis of the usual pipe construction supporting a ladder as: in Fig. 3 light source at the top of the mast. The bracket member l3ihasa semi-circular cavity which is clamped to the mast by the Utelamp 1 2 in the desired position. The member 13 and the semaphore and* has a comparatively short shank l4 whicli-=-- terminates in the verticaldisc 15 which. is parallel with and close to. the mastand. in which the stud bolt 18 is centered. The supporting arm 17 terminates :in the disc 16 which engages the disc 15 and aligns therewith and is held in pivotal relation with 15 by the stud bolt 18 so that the arm 17 is free to rotate about 18 as a pivot and may be locked in position by 18. It is preferred that the engaging surfaces of 15 and 16 be machined or finished to term a true bearing surface for these parts about the stud bolt'18 as a centre.

The lamp device 23 may form a signal in itself or may be used as the source of illumination for the semaphore in Figs. 3 and 4. This device comprises a cylindrical housing for the source of illumination with the projecting lens 24 and is centrally mounted upon a disc 22 formed as an integral part of the housing. The disc 22 rests upon the disc 19 at the extremity of arm 17 and is secured in place by the stud bolt 21 passing through the aperture 20 in disc 19. The aperture 20, it will be noted, is elongated as well as the disc 19 so that the centre of thesignal device 23 can be adjusted horizontally with relation to the centre of the signal mast.

It is apparent that the signal device 23 can be rotated horizontally on pivot 21 and can be secured in any position by 21; and since the arm 17 is rotatableabout the pivot 18 which is at right angles to the pivot 21., the signal device and the beam of light therefrom is rotatable in two angles to each other.

In Fig. 8, the semaphore spectacle 31 moving on the pivot 30 carries the roundels 32, 33 and 34in front of the lens 24 as in Fig. 4 thereby displaying the indication desired. A si hting device il may be embodied in planes at right should be projected.

Where the semaphore is on the opposite side of the mast as at 35, Fig. 4, the device 23 is turned around, to face in the opposite,

direction with the lens at 36 and for this urpose no change of anykind is required in the bracket which is thus universal in its application.

fall on the line H passing through the centre of the mast, that the engagingsurfaces 1516 are at right angles to this line and that the pivot 21 falls on line 0d which is the vertical centre of the signal device.

The signal device can be turned on the pivot 21 and will remain in any position to which it has been moved. The arm 17 has a downward ofiset so that when the lamp is position to which it has been moved. These ivot 18, thus securing a balance enabling t e arm 17 to remain in the Having thus described my invention, I claim: I i
