'My, invention relates to improvements in track gauges of the kind which are adapted to run-along-v a railwaytrack and which serve to indicate the" condition of the track as regards the distancebetween the rails.

The object of my invention is tolpr'ovide a device of this kind which is. simple in con struction and eflicient in operation Iand -which will serve to automatically indicate a device associated with the track gauge which is adapted to mark one of the-rails whenever the gauge of the track exceeds or is less 'than a predetermined width; Other objects and advantages of the invention will be apparent from the following specificatio'n taken in" connection with the ac'companying drawings illustrating the same.

a "Each of the that 11 is mounted a the track when desired and supported free of rod 10 in substantially the same way andthe flanges thereof are forced outwardly against theTrails-12of the track.- Each wheel 11 is rotatably mounted on a sleeve 13 preferably by means of roller bearings L r I ll, these bearings 'being held in @place by any variations, in the-width'of the track, A; further object of the invention is to provide slidab'le;motion longitudinally of this red.

V Y r Preferably the arm 28'1sso formed as to v provide anelectrical contact arm' andthe same is connected toone end of an electric circuit indicated at.26. The indicating scale or plate 25 is -also preferably provided with a plurality of insulated electrical contact points 27 and beneath this scale li provlde a manually operable contact arm 28 which is connected to the other terminal of the. electric circuit 26. It will be understood that the 28 is insulated from the frame and also from arm 23 and maybe placed in con the particular contact27 on which the arm '28 has 9 been placed, the circuit is closed through the electric circuit 26- and by this .means a suitable signal such as a bell 29 -able point may be operated;

mounted on the car A or atany other suit- It may sometimes-be desirable to have severalsignals:arranged to be perated by the movements of the-contact arm 23. Such an arrangement. s shown "particularly in Figure 7 The-plate 25 is provided with a plurality of contacts-25 over which the arm 231's adapted to pass. Eachof these contacts forms aterminal of a separate electric circu1t26 the other-term nal .ofeach of these circu ts being connected to the arm 23.- In

these lamps are preferably of different colors.

To eliect such pivotal moven'entioi the lever 3O, I pivotally secure thereto a link 31,.th1s link also being connected to the'oth'er bar 20. It will thus be seen that when relative movement takes place between. the bars 20 such movement will resultincausingone or thefother of the v arms 130 30? to move toward the rail and thus .brmg one of: the marking devices against the rail.
