SPECIFICATION forming part of Letters Patent No. 651,519, dated June 12, 1900. Application filed September 22, 1899. Serial No. 731,504. (No model.)

To a whom it near; concern:

Be it known that I, FRANcoIs ALeoUD,chief engineer of State railway, a citizen of the Re public of France, residing at La Valliere, Indre-et-Loire, in the Republic of France, have invented certain new and useful Improvements in Apparatus for Testing and Regulating the Position of the Rails in Railway- Tracks, (for which I have made application for patent in France on February 23, 1899,

and in GreatBritain on August 30, 1899;) and- I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This apparatus for testing and regulating in other words, maintaining-railway-tracks consists in part of apparatus for testing or adjusting the necessary distance between the railsfor example, first, after ballasting the permanent Way; second, in straightening the track, and, third, upon the necessary widening of the distance between the rails at curves of small radius in order to facilitate the traveling of locomotives and carriages. The apparatus comprises, further, an arrangement which enables the superelevation of the outer rail at a curve to be tested and adjusted, and, further, for the testing of the rail inclination a suitably-arranged edge is provided in such arrangement.

The accompanying drawings illustrate this apparatus, which is intended to supersede the three contrivances hitherto used in railway maintenanceviz., the iron templet for the gage of way, the templet for the superelevation of the outer rail at curves in the track, and, thirdly, the water-level which must be used for the superelevation of the outer rail, together with the templet.

Figure 1 is a side view of the one end of the apparatus; Fig. 2, a similar view of the other end, and Figs. 3 and 4 are end views.

The end shown in Fig. 1 comprises a steel plate which is straight on' the upper side, the under end being furnished with a shoulder having two interruptions or deviations which correspond to two similar forms in the other end of the apparatus. (Illustrated in Fig. 2.) This steel plate is fixed by means of screws to the left-hand end of a rectangular wooden rule-board. On the steel plate an angle-iron is arranged to turn, which forms an additional deviation for the first deviation of Fig. 2 and can be turned into and out of the working position, as desired. In order to turn this angle-iron into the working position, it is sufficient to move it to the left until the one arm rests on the stop shown in Fig. 1. The position of the angle-iron (indicated by dots, Fig. 1) shows the working position,while the position represented in unbroken lines is that of rest. These two parts of Fig. 1 each have abronze tablet, on which the corresponding gage of way is indicated by figures.

Fig. 2 likewise shows a steel plate and, in fact, that of the other end of the apparatus, which is furnished at the lower end with a shoulder having two interruptions or deviations corresponding with those in Fig. 1. This part, Fig. 2, is fixed t0 the other end of the wooden rule-board. The upper part of the plate, Fig. 2, is of trapezium form with rounded-oft edges, and carries a pendulum which rests on a knife-edge and in its position of rest indicates the vertical in whatever position on the two rails the apparatus maybe. A staple prevents excessive swinging of the pendulum, while a widening at the lower end of the latter serves to keep it in the right direction. The lower end of the pendulum terminates in a point and moves over a scale.

This scale is so arranged that its zero-point lies in the middle of its graduations. If the pendulum is over the zero-point, the surfaces of the apparatus lying on the upper edges of the rails form a horizontal. The variations of the point of the pendulum from the one or other side of the zero-point indicate the deviations of the upper edges of the rails to the one side or the other.

This apparatus enables the track to be promptly tested and the superelevation of the one rail-head at curves in the track to be determined without the necessity of employing a water-level.

The upper part of Fig. 2 has a wedge somewhat deviating from the perpendicular for testing the inclination of the rails.

The arrangement can be employed for all kinds of railway-tracks.

What I claim, and desire to secure by Letters Patent, is

1. Apparatus for regulating and testing the position of the rails in railway-tracks, distinguished by a wooden rule-board, the one end of which bears on a steel plate with a shoulder which has two interruptions or deviations and a turning angle-iron for the formation of a further deviation while the other end like wise has a steel plate furnished with similar deviations and having on its upper side a raised extension on which a pendulum hangs, which indicates on a scale the position of the apparatus, laid on the upper edges of the rails in relation to the horizontal.

2. Apparatus for regulating and testing the position of the rails in railway-tracks, distinguished by a wooden rule-board, the one end of which bears on a steel plate with a shoulder which has two interruptions or deviations and a turning angle-iron for the formation of a further deviation while the other end likewise has a steel plate furnished with similar deviations and having on its upper side a raised extension on which a pendulum hangs, which indicates on a scale the position of the apparatus,laid on the upper edges of the rails, in relation to the horizontal, while an oblique edge of the extension serves for testing the inclination of the rail.

In testimony whereof I aflix my signature in presence of two witnesses.

FRANCOIS ALGOUD.
