Specification of Letters Patent.

Patented July 1 1913.

Application filed January 22, 1912. Serial No. 672,725.

To all whom it may concern Be it known that I, MANZER WILSON Dowmn, a subject of the Kin of Great Britain, residing at Presque sle, Maine, United States of America, have invented certain new and useful Improvements in Con'ibii'lation Track-Gages and- Recorders; and I do hereby declare that the following is 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.

The invention to bchcreinafter described relates'to a combination trackgage and recorder. s

In order to more clearly disclose the construction, operation, and use of the invention, reference shonld'be had to the accompanying drawings forming part of the present application.

'lhroughout the several figures of the drawings like reference characters designate the same parts.

In the drawings: Figure 1 is a top plan view of the invention, as applied; Fig. 2 is a rear end elevation, with some details in section; Fig. 3 is a vertical cross sect-ion on line 3-3 of l i'g. ],looking in the direction of the arrow; Fig. 4 is a vertical cross sec-- tion on line 44 of Fig. 1, looking in the direction of the arrow; Fig. 5 is an enlarged, detail, side elevation of the stamping mechanism; Fig. 6 is an enlarged front View of the elevation indicator, and the devices for recording the. elevatiinis; Fig. 7 is an enlarged rear view of the width gage; Fig. 8 is a side elevation of the same; Fig. 9 is a top plan view of themechanism for feeding the record strip; Fig. 10 is a side elevation of the same; Fig. 1.1 is an enlarged front view of the alarm actuating devices; and Fig. 12 is a top plan view of the type frame and type. t

The main objects of the jnvention are to provide a machine whicli will not only measure and indicate variations in height and spacing of the track rails, but one which will also accurately record such measurements.

The machine may be mounted upon and carried by the frame work of an ordinary hand ear or velocipedc car. As shown in the drawings, the invention is applied to a relocipede car. In this construction, the car platform is supported by a sectional axle comprising a stationary or fixed section 1 provided with an inner cylindrical end 2 with surrounding collar or flange 3; and a laterally sliding and non-rotatable section 4 provided with a tubular inner end 5 to slidably receive the end 2, and having a collar orflange 6 similar to the flange 3. Between the flanges 3 and 6 is arranged a coil spring 7 which tends to force the collars 3 and 6 apart and thus keep the section 4 in its outermost position. To the outer end of each axle is secured the usual supporting flanged Wheel. The spreading action of the spring 7 tends to make the laterally movable wheel of axle section 4 follow accurately all irregularities in the widths or the spread of the rails.

Beaded in the center of the forward part of the platform ofthe car is a type frame 8 in which are arranged two rows of type, one for recording variations in height and the other for recording variations in width. Each of these rows is arranged in two sections, each section reading from the longitudinal center of the frame toward the end of the frame. One section of the row for re cording variations in height has each type bar headed with the letter R (right hand rail) and the other section has each type bar headed with the letter L (left hand rail). One section of the row for recording variations in width or spacing has each type bar headed with the letter N (narrower than the required standard) and the other section has each type bar headed with the letter W (wider than the required standard).

Pivotally connected to the movable axle section 4. is an elbow arm 8 the upper end of which is off set to form a stamping head 9. The upper part of the arm 8 extends through an elongated slot in the platform and running parallel with the rear part of the type frame. Thus, the stamping head 9 will fall directly above one or another of the type platform, from either side of the center, in.

accordance withthe movements of the axle section 4. 'Thus, in order to record the vatype bars and stamping head 9, and then drive the head down into operative position. The paper feeding devices will be later described.

The stamping devices comprise a gear wheelll fixed to the flanged wheel of the axle section 1, a shaft 12 journaled in suitable hearings on the platform and provided with an actuating cam 13 and a gear 14 which intermeshes with and is driven by the gear 11. The cam 13 is arranged directly above the row of type for recording variations in width, and extends from end to end of the type frame. Thus, as it is rotated, it will engage and depress the stamping head 9, at whatever point the head may be. As

the stamping head is depressed, it Will' record the particular measurement of the type bar over which it happens to be. The gears 11 and 14 are so proportioned, of course, as to actuate the stamping head at frequent and regular intervals or distances, as the car travels on the rails. It is desirable, of course, to efiect a regular and uniform traveling of the record strip on which the figures are marked, so that the various figures or measurements'will be clearly and uniformly spaced. Thus, a carbon strip or ribbon and a recording strip or ribbon are led from supply drums 15 and 16 respectively, at one side of the platform, about suitable guide pulleys, across the type frame, and rewound upon suitable receiving drums 17 and 18, at the opposite side of the frame. In order to rotate the receiving drums 17 and 18 to cause travelof the strips, ratchet wheels 19 and 20 are secured to them and the teeth of these wheels are engaged by fingers 21 projecting from the shaft 12 and acting upon the teeth as pawlsv to cause step by step rotation of the drums. Suitable tension devices such as leaf springs 22 may be usedto hold the paper andcarbon strips .taut agaihst sag ing.

In order to record the variations in height, a pendulum, cam, and plungers are used'.- The pendulum 23 is suspended di- 'rectly abov e the longitudinal center of the type frameand adapted 1 to swing freely,

toward and from the rails of the track. Any movement from an exact vertical position will represent an unevenness inthe elevations of thetwo rails. In order to give a visible indication of such variations, an indi cator dial24 and needle 25 maybe used.

The needle is worked from the pendulum gearing, the normal evenness in. the elevations of the two rails. The 'graduations read increasingly from this point in opposite directions around the dial, one side showing elevations-of. the

right hand rail, and the other sideshowing elevations. of the left hand rail, as in Fig. 6. The lower end of this pendulum is off set to form an arm 26 provided with a head 27 having-a bore in which is slidably mounted a spring supported selector plunger 28. The lower end of, this plunger. is always above one oranother of a line of spring supported stamping plungers 29 slidably mounted in a block30 suitably supported in the frame work. of the machine a slight distance above the type frame and in such position that the plungers 29 will come directly above the row of type for recording variations in elevation.

In order to actuate the selector plunger 28 an arcuate presser bar 31 is provided.

This bar is slidablysupported in posts'or brackets and has its'opposite ends off set and set upon coil supporting springs This presser bar over lies the topof the selector plunger throughout the entire swing of the-pendulum. Therefore, depres sion of the presser bar will effect operation of the selector plunger, at whatever position the plunger may be. Likewise, the upper ends of the stamping 'plungers are arranged in an are parallel to the presser bar 31. In order to actuate the presser bar 31, h cam 33 is provided.- This cam is carried by a shaft 34 journaled in the framework of the machine and driven by means of intermeshing pinions 35 and 36 on the ends of shafts l2 and 34 respectively. These pinions may proportioned so as to cause operation of the selector and sta'mpin plungers at the saint time as the stamping ead is operated by its cam 13, thus causing the variations in width or spacing, and the variations in elevatiw. to be recorded for the same point of track at the same time. Or, other p1 tioning of thegears-may be used, if desired.

From the above, it will be seen that the variations in elevations of the rails will be both indicated and recorded at the same time; The graduations on the diflg corre spond, of course, tothe characters on the recording types. Thus, the indicated variawith the recorded variations. It is, of

course, desirable to render visible'the varia tions'of width or spacing of thefrai-ls. To this end, an actuating rod 37 is pivotally connected to one endof the movable section f" of. the axle and has its opposite end made fast-to the rod or axle of one member of a clock train gearing for operatingan index needle '38 which cotiperates, with a dial 39 in a casing'40. The casing 10 also incloses and protects the supply drums for the carbon and paper ribbons. The normal or zero position ofthe needlecorrespo'nds to normal width; or spacing of the rails..-jThe graduations read-increasingly in opposite directionsfrom this-point, the graduations 'tions'may bemade to correspondexactly in width or space.

is the provision of means for giving a sig- .\'ation and width.

'nal or alarm when-the space or width exceeds a certain predetermined amount. This comprises an electric bell 41 included in a normally open electric circuit, one wire of the circuit being connected to the elbow arm 8 and the other wire being connected to a bar 42 provided with a'screw threaded end 44 and slidablymounted in a strap 43 se cured to the under side of the platform of.

the car. The screw threaded end extends through a perforated ear and the bar may be adjusted longitudinally in its bracket toward or from the arm 8, as desired. As soon as the arm 8 touches the end of bar 42, the circuit will be closed and the bell will ring. As previously explained, the outward movement of axle section 4 carries with it the arm 8, thus,'moving the arm toward the. end of rod 42. The engagement between the two may be so timed or arranged as to give the alarm or signal at the instant that any desired width or spacing has been exceeded. A similar rod and electrical connect-ions may be arranged on the other side of the car platform to give an alarm or signal at the instant that a minimum width or spacing has been reached, as will be obvious.

In order to make a complete record so that the variations shown on the record may be easily found on the track, a distance re cordcr has been devised and is arranged to mark or record each 1/20 or other fraction of a mile and each complete mile, such marks being madedirectly on the record strip and, preferably, between the sets of measurements indicating variations in ele- Thcse distances are re corded by spring supported stamping plungers 47 and 48, actuated by cams 45 and 46, on shafts 49 and 5t), suitably journaled in the frame. The cam 45 actuatcs plunger 47 for recording each l/QO or other fraction of a mile, and :e cam 46 actuates the plunger 48 for recording each complete mile. To the shaft 34 is fixed a sprocket wheel 51 which engages and drives a sprocket chain which, in turn, passes about and drives a large sprocket wheel 53 fixed to a counter shaft ()n this counter shaft is fixed a pinion 55 which meshes with and drives a gear wheel 56 fixed on a second counter shaft 57. ()n the shaft 57 is fixed a small sprocket 58 which drives a sprocket chain 5t). This sprocket chain, in turn, drives. a larger sprocket wheel 60 fixed to a third counter shaft- (31. To the end of the shaft 61 is'fixed a small sprocket wheel 62 which drives a sprocket chain 63, the sprocket chain 68, in turn, passing about and driving a small sprocket Wheel 64 fixed to the end of shaft 50 for driving the cam 46 which operates the spring supported stamping phpigers 48 for recording each complete 1111 e.

For recording each 1/20 or other fraction of a mile, a sprocket chain 65 and sprocket wheels 66 and 67 are used. This connection causes rotation of shaft 49, of course. Thus,

the cam 45 will be rotated to actuate thespring supported stamping plunger 47 for recording each'1/2O or other fraction of a mile. he wheels of the car are rovided with specially off set flanges to acilitate passing of switches, frogs, and the like.

It, is thought that the operation and use ,of the invention will be clear from the preceding detailed description.

Ghanges may be made in the construction, argangement, and disposition of the several parts of the invention without in any way departing from the field and scope of the same, and it is meant to include all such within this application wherein only a'preferred form has been disclosed.
