To tZZ whom it may con/cern:

Be it known that we, THADDEUs ELLrs and GEORGE HERNDON PUEvrs, citizens of the United States, and residents of Lester, in the county of King and State of Washington, have invented a new and Improved Automatic Track-Inspector, of which the following is a full, clear, and exact description.

Our invention relatesto apparatus for examining the condition of the tracks of railways, and more particularly to those for determining the variations in the gage and level thereof.

It has for its objects the provision of a convenient and effective apparatus of this class.

It consists in the various features and combinations hereinafter described, and more particularly claimed. l

Reference is to be had to the accompanying drawings, forming. a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a transverse section on the line 1 1 of Fig. 2 of one embodiment of our invention. Fig. 2 is a side elevation of the same attached to a car. Fig. 3 is a longitudinal section through the gage-indicating mechanism on the line 3 3 of Fig. 4. Fig. 4 is a transverse section on the line 4 4 of Fig. 3. Fig. 5 is a longitudinal section through the level-indicating mechanism on the line 5 5 of Fig. 6, and Fig. 6 is a transverse section therethrough on the line 6 6 of Fig. 5.

F designates a frame which is formed in two sections, preferably made up of tubular members. One of these sections consists of a horizontal arm 10, at the-outer end of which is a T-fitting 11, and at the opposite end of ing extension 12, -carrying the axle fora wheel 13, ada ted to rest on one of the lines of rails R. The arm 1() has secured to its inner extremitya sleeve 14, which may be bolted thereto, and intothissleeveprojects an arm 15 of the Vother'frame-section, this arm carryingl the axle of the wheel 16,

l which'coacts with the other line of rails. The

arm 15 is permitted a lon itudinal movement in the sleeve, while held against rotation therein or separation by bolts or pins 17,1ixed in the arm and extending through op osite the s eeve. To force the two sections from one another and normallymaintain the flanges of the wheels in contact with the rails, a spring 19,

preferably of spiral form, is provided within the sleeve, having its ends contacting with the adjacent ends of the section-arms. This allows for a movement of the sections relatively to one another when there is any variation in the gage of the track'over which they are assing.

o strengthen the frame, a brace 19@L may be connected to the frame members 12 and 14, and to the sleeve, conveniently by encircling it, may be attached a draft-bar 20, the end of which may be fixed to the hand-car or other track-vehicle V, by which the inspecting apparatus is to be drawn.

From the side opening of the T 11 extends anarm 21, having at its outer end an elbow 22, this elbow carrying an axle member 23, upon which a third wheel 24 is journaled. To strengthen this portion of the structure, a brace 24a may connect the arm 21 with the sleeve 14.

About the outer or open end of the sleeve is secured a clamp 25, havingprojecting from beneath it a plate 27, uponwhich Ais sup orted acasing26, referablyprovidedwitha 'nged top 26a. The casing may be adjustably secured uponthe plate by bolts 28, extendin through slots 29 in the plate, it being clamped in its adjusted position by thumb-nuts 30, situated on the bolts beneath. the plate.

Across an opening 31 in the front of the casing is located a scale 31a, and over this scale moves a pointer 32, which is fixed to the arm 15.' The zero of this scale is situated 'substantially at the center, and the aduations upon each side of this may be mail to read in units of track-gage. The relative movement of the frame-sections operating under the contact of the wheel-flanges with the track and under the influence of thespiral spring results in the pointer moving to one side or the other as the gage changes. The pointer may-be' brought to the normal or zero position when the car is resting upon a portion of IOO which is threaded through the pointer at 36,

this arrangement permitting its adjustment toward and from the paper. The record-receiving ribbon passes from a supply-roll 37, which is journaled at 38 in an inner wall 38a of the casing, which wall forms between it and the end of the casin a chamber 38". At the opposite end the rol 37 is journaled in a door or closure 39 of an opening in the casing of sufficient size to permit the admission of a full roll of the ribbon. This door may be secured in place by buttons 40 and is preferably provided with a handle 41 for convenience in removing or applying it.` At one end of the roll may be situated a spring-'tension device 41a to prevent too free rotation thereof. From the supply-roll the ribbon passes over a suitable guide-roll 42 and then u ward over a platen 43, which is situated on t e opposite side of the ribbon from the stylus and serves as an operating or contact surface therefor. This laten may be mounted by means of a spin le 44, operating in a socket 45 ,dprojecting from the rear wall of the casing, an held against rotation by a projection 46, extending through a slot 46a in the Socketwall. Between the adjacent ends of the spindle and socket is a spiral spring 47, which forces the platen with a proper degree of pressure against the ribbon. From the platen the ribbon operates over a drivingroll 48, which is referably provided with an outer layer 48a o material, this roll bein journaled at one end in the outer casing-wall and having the other end extending through the inner wall 38a and journaled in the outer wall, there being an intermediate shaft 49 withinvthe chamber.

, Above the driving-roll is a tension-roll 51, the op osite journals 52 of which move in vertica slots 53 in the outer and inner casingwalls, allowing the roll to rest yieldably upon the ribbon. From beneath this tension-roll the ribbon rises to a receiving-roll 54, which is shown as journaledin the cover of the casing. This roll 54 is preferably of the spring or curtain-roll typp to enable it to `exert a tension u on the ri bon totake u the slack from t e driving-roll. It is pre erably provided with a crank 55, by which it may be rotated to secure the necessary tension, and with a pawl and ratchet 56Vto hold this tension when it has been secured until the ribbon has been properly attached. Both the supply and receiving rolls may have at their ends cheeks or retaining-flanges 56a.

On the shaft 49 is a gear 57, which meshes with a suitable train of slow-down gearing 58, connectin with a shaft 59, journaled in the casing-wa l 38a and in the adjacent outer wall. Upon this latter shaft is fixed a pulley 60, which is connected b a belt 61 with a pulley 62 upon a main s aft 63, extending transversely of the frame and journaled in brackets 64, secured to the sleeve and fixed rubber or similar yieldable vcollar 82, which may arm. Upon the opposite end of this shaft 63 is a pulley 65, which is connected by a belt 65a with a pulley-surface 66, carried by the hub of the wheel 24. Y The diameter of this track-wheel being known, it is only necessary to have a determinate ratio of gearing connecting it with the mechanism for advancing the record-receiving member to have this latter moved at a definite rate, so that a longitudinal scale of distances may be inscribed thereon. Then when beginning the inspection if this ribbon is started at the Zero-point in its movement from the roll the departure of the mark made by the stylus from the Zero or standard gage may be referred to the exact place upon the line at which it occurs. The wheel 13 may also be of deiinite diameter and is shown as carrying a projection 67, which actuates a cyclometer or like instrument 68, carried u on the frame and enabling the distance trave ed to be read by the operator at any time without reference to the ribbon within its casing.

About the sleeve 14, situated substantially at the center of the frame, is a clamp or collar 69, carrying a standard 70. Secured near the footcof this standard is a pair of arms 71 71, carrying a plate 72, furnishing a support for a casing 73, which may be generally similar to that previously described. The casing may be adjustably secured on the platel by bolts 74, having suitable finger-nuts passing through longitudinal slots 75 in the plate. At one side of the casing 73, having an opening 73a, registering with an opening 73b therein, is secured a sector-shaped casing 76, through the upper extremity of which projects an arm 77, carried by the standard and preferably braced by a diagonal member 7,8. This arm 77 has within the sector-shaped casing a cylindrical portion 79, which projects through the front of said casing and is threaded at its outer end to receive a retainin -nut 80. Within the casing 76 upon this cylindrical portion oscillates a pendulum or level-indicating member 81, one side of thev supporting-boss 81EL of which contacts .with the inner casing-wall and the other with a be clamped u on the At the low er end of the endu um is a weight or bob 83, and from t 's projectsv a pointer 84, operating over a segmental scale 85, situated at the bottom of the casing 76. The zero of this scale is located at its center, and the movement of the pointer to one side or tlieMother-indicates by suitable graduations thereon the elewkatifonefrther rail of the track. The pendulum may kerretainerlg in its normal plane of oscillation by a guide- IOD IIO

bracket 85a, which is here shown as furnish- 125 ing the surface upon which the scale is upturned ends v86, and between these is alug 87, carried by the front of the casing. 13o

Through the arm ends and the lug is'threaded a screw 88, and byrotating this, the nuts of the bolts 74 first having been loosened, the casing may be adjusted on the frame to bring its Zero. into coincidence with the pointer when theapparatus 1s upon a true or level track. j

The pendulum carries a stylus or pencil 89, which may be mounted in a socket 90, threaded through the weight at 90a for adjusting the pencil with reference to a ribbon or record-receiving member 91.. This ribbon is supported and moved by elements similar to those previously described in connection with the gage mechanism, and they have therefore been desi nated by the same reference characters. ts gearing is driven by a pulley 92, from which a belt 93 passes over a pulley 94 upon the shaft 63. This eHects the advance of the ribbon Aat a definite rate, as in the companion mechanism, and then when the car is upon a track which departs from the horizontal the amount of variation will be indicated by the swing of the pendulum both upon the scale and by the mark upon the ribbon.

In the use of our improved a paratus each casing is supplied with a suita le roll of paj per applied through the removable closures in the openings. The end ofeach roll is drawn over the 'Guide-roll and platen, over the driving-roll, under the tension-roll, and onto the supply-roll, to which it is secured, this roll having previously been iven suflicient tension to take upthe slac The frame may now be placed upon a track which is standard for the gage upon which it is desired to operate and which is also perfectly level and both the gage and level indicating mechanism adjusted by the 4movement of their casings until the pointers u on the arm and pendulum coincide with t standard graduations upon the scale.

V will be evident that this may be readily effected for each mechanism without disturbing the other by virtue of theentire inde pendence of the casings and adjusting elements. The apparatus is now attached by itsV connecting-bar to the car which is to draw it and upon being moved over the track will give to t e observer by the position of p the pointers upon the scales exact readings of both the gage and level. At the same time the contact of the styli with their ribbons will furnish a permanent record of the` movements of the indicating mechanism or rofiles of the elevation and gage. This Wil enable the two records to belaid sideby side and very perfect comparisons made.
