Claims.

This invention relates to a device for use in preparing graphs or diagrams to indicate and record irregularities in surfaces, and has particular reference to a device especially designed for use in preparing graphs or diagrams to record deflection and Wear in the profile or top surfaces of railway rails.

In the art of track maintenance there has developed to a considerable extent the practice of reconditioning worn and battered rail ends by a welding process involving the building up of the worn and battered areas by the application of compensating metal thereto. In order that this work may be performed efficiently and accurately it is the practice to prepare graphs or diagrams indicative of the worn and battered condition of the rails for the guidance of the workmen, and heretofore, the preparation of these graphs or diagrams usually has been effected by the aid of a straightedge and a taper gauge. This method of preparing the graphs or diagrams is, however, quite tedious and time consuming in that it involves an elaborate procedure of numerous measurements and notations. Moreover, it is further objectionable because of the chances of error involved in the manual taking of the measurements and the making of the notations.

Accordingly, the general object of the invention is to provide a simple, inexpensive device whereby graphs or diagrams indicative of irregularities in surfaces, especially in the profile surfaces of rails, either for the use of workmen in reconditioning the rails or for rail wear record purposes, may be produced quickly and easily and with extreme accuracy.

With the foregoing general object and various other purposes in view, which will become more fully apparent as the nature of the invention is better understood, the same consists in a device embodying the novel features of construction and the novel combination and arrangement of parts as will be hereinafter more H fully described, illustrated in the accompanying Figure 4 is a detail view illustrating one way of mounting the marking implement.

Figure 5 is a view similar to Fig. 3 illustrat-- ing the application of a gauge to the device; and

Figure 6 is a plan view illustrating the gauge.

Referring in detail to one practical embodiment of the invention as illustrated in the drawing, it will be observed that the device is inclusive essentially of a supporting base, desig nated generally as A, which, as shown, preferably is in the form of a channel member of suitable length, depth and width, open at its bottom and having side walls id and a top wall it, the top surface of which is planar.

Extending upwardly from the rear side of the base A, or from the top H of the base near the rear side thereof, either as an integral part of the base or as an element separate therefrom and suitably attached thereto, as by riveting or welding, is a vertical platen or plate l2 of suitable height and of a length such that it terminates at its ends adjacent to but inwardly of the ends of the base.

Formed through the plate l2 near each end thereof is a narrow, vertical guide slot !3, while rising from the top wall ll of the base near each end thereof is a pin [4.

On one of the pins I4 is mounted a spool l5 having a recording strip [6 of paper or other suitable material rolled thereon, while on the other pin [4 is mounted a second spool I5 onto which the strip iii, after having first been threaded through the slots E3 and across the front face of the plate I2, is to be rolled. In this connection the pins i l may be fixed to the base and the spools l5 may be rotatably mounted thereon and may be provided with suitable finger engageable formations to effect their rotation, or, alternatively, the pins may be rotatably mounted on the base and may be provided with suitable finger knob formations M, to effect their rotation and the spools may be non-rotatably engaged with said pins, as shown. In either event, to prepare the device for use the spools are mounted on the pins and the recording strip I5, is, as aforesaid, partially unwound from the first mentioned spool, passed forwardly through the adjacent slot [3, extended across the front of the platen-plate l2 and rearwardly through the other slot [3 and finally attached in any suitable manner to the second mentioned roll. Thus, the section of the recording strip exposed at the front of the plate l2 between the slots l3, i3 is adapted to be marked to constitute a graph or diagram, and when the making of one graph or diagram has been completed a new section of the recording strip to be marked to constitute a second graph or diagram is brought into operative position across the front of the plate l2 between the slots I3, l3 simply by rotating the second mentioned spool Hi to wind the previously marked strip section thereon. Thus, also, when finally the entire strip l6 has been used in making graphs or diagrams, the latter all are wound as a continuous suitably notated record strip on the second mentioned spool.

Formed in the top wall I I of the base A and extending substantially throughout the length of said wall is a slot I1, and in this slot is disposed an arm IB which may have flat side faces and which is of a width to neatly fit said slot whereby it is held against rotation, but is, however, permitted to move freely in a vertical direction as well as to be freely shifted longitudinally relative to the base.

At the bottom of the arm IB is carried a small roller I9 for floating contact with the surface to be gauged, while on said arm, above the top wall ll of the base A, is engaged a finger block 20 through which the arm is freely movable vertically and which is to be grasped by the hand for moving said arm longitudinally along the slot H, the block 20 having sliding engagement at its under side with the top face of the base Wall, H to either side of the slot H as shown.

On the arm l8 below the top wall ll of the base is mounted a washer 2| which engages the under face of said wall and through which the arm is freely slidable, while between this washer and a suitable stop or abutment 22 at a lower point on the arm, which stop or abutment may be constituted by a second washer held against downward movement relative to the arm by a cotter pin 23 extending through the arm, is interposed a light expansion coil spring 24 which tends constantly to urge the arm l8 downwardly.

Near its upper end the arm l8 carries a suitable marking implement or stylus 25 such as a lead pencil, which extends rearwardly from said arm for cooperation with the portion of the strip l6 which is exposed at the front of the plate 12, the said marking implement preferably being mounted on the arm l8 in such manner, not entering into the invention, that it may be held normally retracted and disengaged from the strip I6, as by'the stop 25 for projection when released, into yieldable engagement with said strip as by the spring 25 as suggested for instance in Fig. 4. The stop 25 is carried by the pencil and when the pencil is rotated to aline said stop with the recess shown in the arm I8 the spring 25 acts to project the pencil. The pencil is manually retractable against the force of the spring 25'" and when retracted and rotated to disaline the stop 25 from said recess the stop then bears against the front face of the arm l8 and holds the pencil retracted.

Preferably the side walls [0 of the base A are provided at or near their ends with depending foot formations 26 of short length for engagement with the top or profile surfaces of the rails to non-rockably support the device thereon. Moreover, the front side wall Ill is suitably cut away to provide a centering pointer 21 midway between the ends of the base, or said wall otherwise is formed or marked to provide an index for centering alinement with the gap between the rail ends to facilitate proper positioning of the device on the rails with relation to the joint between the rail ends, while in vertical alinement with the pointer or index 21 the plate i2 is notched as indicated at 28 or otherwise is indexed as a guide to marking or indexing the exposed strip section 16.

In the use of the device, assuming that a sec tion of the recording strip 1 6 has been positioned across the front of the platen l2 as shown, the arm l8 with the pencil 25 held retracted is moved to one end of the slot I1 and the base A is placed upon the rails R, R, with the pointer 21 alined with the gap between the rail ends and the foot formations 26 engaging substantially unworn portions of the rails beyond the worn or battered portions thereof indicated as r. The pencil 25 then is released to engage the recording strip l6 and the arm I 8 is moved slowly towards the other end of the slot 17. Under the influence of the spring 24 the roller l9 follows the contour of the worn or battered profile surfaces of the rails and consequently, through the arm l8, controls vertical movements of the pencil 25, so that, when the arm i8 finally has reached the second mentioned end of the slot ll, there has been marked on the recording strip section iii a line which corresponds exactly to the contour of the worn or battered profile portions of the rails. By the aid of the index 28 the graph or diagram thus produced is marked or indexed at a definite 3 point corresponding to the position of the pointer 7 relative to the rails. Identification data and such notations as may be necessary or desired then are placed on the graph or diagram to complete the same, whereupon a new section of the strip H5 is brought into position across the front of the plate 12 for the making of another graph or diagram.

The base of the device may be and preferably is of such less width than a rail that the device may be shifted laterally relative to the rail to obtain profile graphs or diagrams indicative of worn or battered conditions adjacent to the sides of the rail. Moreover, the slot l'l may, if desired, be formed nearer to one side than the other of the base so that by reversing the device end for end graphs or diagrams indicative of rail profile conditions quite closely adjacent to the sides of the rails may be obtained.

The recording strip l6 may, if desired, be in the form of strips of graph paper ruled horizontally and vertically, but this obviously is not necessary since a worn profile condition indicated by any particular graph or diagram may readily be ascertained from the graph or diagram. simply by drawing a straight line between the high points of the diagram at the ends thereof.

When finally the entire recording strip !6 has been utilized in making graphs or diagrams and the latter have been rolled onto the strip receiving spool, a compact, unitary record, convenient for use and storage and indicative of worn rail conditions at a plurality of separate locations is obtained.

Figures 5 and 6 of the drawing illustrate a preferable construction which includes an indicating gauge in conjunction with the recording device heretofore described to indicate the extent of the irregularities in the surface being recorded and by means of which accurate notations of de flection and wear may be made. While an indicating gauge of any construction and mode of operation suitable for use with the device may be employed, the gauge illustrated in the present instance and designated generally as G is of a Iii known type, as disclosed for example in Reisner Patent No. 1,419,306, wherein longitudinal movement of a foot 1 relative to a casing 0 effects rotation of a pointer 10 over a dial d to indicate in thousandths of an inch endwise movement of the foot relative to the casing. The casing c is provided with a supporting stem 3, and in accordance with the invention this stem is engaged in an opening in the arm l8 and is secured therein as, for example, by means of a set screw s, whereby the indicating gauge is affixed to said arm for movement therewith. The indicating gauge is disposed to have its foot track over the planar upper face of the top wall ll of the base A. Consequently, when the arm I3 is moved along the slot I! and is raised or lowered in accordance with irregularities in the surface en gaged by the roller IS, the indicating gauge is correspondingly raised or lowered and, due to the cooperation of the foo-t with the planar surface of the body wall ii, the indicating gauge accurately indicates the extent of the irregularities. Preferably the strip i5 is vertically ruled at suitably spaced intervals, and when using the indicating gauge G the strip is brought to a position with one of its ruled lines alined with the indices 28, 2?, the latter of which is alined with the gap between the rail ends. Said line then is suitably marked or identified, whereafter the arm l8 is moved along the base A and the amount of rail profile wear or deflection as indicated by the gauge G at different points in its movement with said arm is noted on the strip having the rail profile inscribed thereon as described. The vertical lines on the strip serve as a convenient guide for the making of such notations. Thus, an txtremely accurate graph or diagram. indicative of the deflected, worn and battered conditions of the profile surfaces of the rails of a rail joint may readily and easily be made.
