SPECIFICATION forming part of Letters Patent No. 449,855, dated April 7, 1891.

I Application filed February 25, 1890, $erial No. 341,729. (No model.)

To aZZ whom it may concern:

Be it known that I, THEODORE J. KING, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Track Clearing and Lubricating Devices; and I do 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 invention relates to attachments for cars, and is designed as an improvement upon the devices shown and described in the application filed by me November 9, 1889, Serial No. 829,811.

The main object of the present invention is to more effectually clean the groove of the track or rail at the curves, which has heretofore formed a trap or receptacle for a great portion of dust and dirt brought by the brushes or scrapers from the straight portions of the rails.

\Vith the brushes and clearing devices heretofore used it has been found that as the car nears a curve its forward portion deflects from its true course. As a consequence the clearing devices carried thereby follow the movement of the car and either leave the rail altogether untouched or move in such a manner as to heap the dirt and dust into the grooves, thereby increasing the friction at this point, and consequently increasing the draft.

Another source of annoyance and expense has been the frequent lubrication of the rails at curves, and in some instances this has been from the following description and claims, when taken in connection with the annexed drawings, in which-- Figure 1 is a view of a portion of a car, showing myimprovements applied and the pedal-lever depressed with the clearing devices brought into position. Fig. 2 is a perspective View of the angular lever or rockshaft removed from the car and carrying the brushes and scrapers, and Fig. 3 is a rear View of the scraping arm or point with my improved means for holding the same and allowing a yielding and lateral movement thereof.

Referring by letter to said drawings, A indicates a portion of a car, which may be of any ordinary or approved construction.

Arranged beneath the seats or at any other suitable points therein, and in advance of the .front wheels, are hopper-shaped receptacles B,which in some cases may hold sand and at other times hold water, oil, or other liquids designed to lubricate the track or rails. In using liquids these receptacles should have a cover so as to prevent splashing and wasting of the liquid. Leading from the outside of this receptacle (there being one on each side of the car) is a flexible tube C, which is in most respects similar to the tubes used in the construction shown in my application above referred to.

D indicates an angular rock-shaft, which is provided with a weighted or gravitating arm a, and E indicates an angular lever,both of which are of the same construction as shown in said application referred to. The angular lever E is provided With the vertical branch I), and is journaled to the frame of the car at the angle 0, and the rock-shaft D is also journaled to the car by staples d or other suitable devices, whereby it may be allowed to play freely in its bearings. The depending branches 6 of the angular rock-shaft carry the advanced clearing-points F, and secured to the rear sides of these arms or branches are the arms G, which hold the scrapers 1-1.

The arms G, which are secured to the branches of the rock-shaft by bolts or other suitable fastening devices, are provided in their rear sides with a recess f, designed to receive the upper end of the scraper H, and

above this recessf another recess, which is designed to seat a spring-arm g, although the spring may be secured to the arm by any suitable means. The scraper H, which should have its lower end of a form corresponding to the face of the rail, is pivotally secured to the arm G by a pivot pin or stud Z, and above this pivot-point said scraper is provided with a transverscly-arraiiged curvilinear slot 7a, which receives a stud in, fixed to the arm G. The head of the arm or scraper II, above the curvilinear slot 7;, is provided with a vertical slot u to receive the lower end of the yield ing or spring arm By this construction it will be seen that the scraper ll, being pivoted to the arm G, the spring'arm r will normally hold the scraper in the position shown in Fig. 3 of the drawings when traveling on a straighttrack; but as the car reaches a curve and the lower end of the scraper is engaging the rail the said scraper, having its fulcrum at the point 1', will act upon the springarm 9 so that the same must give laterally and allow the lower end of the scraper to keep contact with the rail in its entire passage around the curve.

JVhile l have shown and described an arm with a recess carrying aspring and a scraper with a curvilinear slot, yet I do not wish to be understood as confining myself to devices of such construction.

I attach importance to the employment of the lubricating device and the fact that the same is adapted to follow the curve and opcrate simultaneously with the scraping and brushing devices.

The tube G is guided to the rail by passing through an eye L. preferably formed on the l)l'OO1ll-ll0i1(1,ttlltl the broom 1 is interposed between the tube and the scraper and secured to the latter, as shown. In order to give stiffness to the tube, itmay have a thimblc M, of wood or other suitable materiahand in this non-yielding hollow piece I provide a key or valve-seat to receive a key or valve N, having an angular arm P, which is connected with the car-body by a rod R, as shown. By this means it will be seen that as the rockshaft is turned so as to let down its angular branches the rod will be drawn on the key, so as to open the passage in the tube, and the tube, being connected with the scraping and brushingelements, will be brought into action so as to deposit water, oil, or other lubricant from the receptacle upon the track as it has been freed from dirt. by the scraper and brush.

Vhile I prefer to use the rod R for opening the valve in the tube, yet such rod in some cases maybe dispensed with and means provided at the tube-guide for that purpose.

Directly beneath the car is a sliding valve S, which is connected with the rock-shaft arms by a connection T, and is used when carrying'sand in the receptacle. It is, however, obvious that this latter valve might be dispensed with, and in some cases the connection T might be detached from the branches of the rock-shaft when it is not desirable to use the valve S.

In operation, when the driver or attendant desires to scrape and brush the rails, he simply presses his foot upon the pedal-lever and raises the gravitating-arm. This movement will bring down the scraping-point and also the brush, and in passing a curve if he desires to oil or lubricate the rails he simply increases his pressure on the lever, when the scraper, which is preferably of spring-steel, will give suiticiently to move the broom-head to a point that will cause the rod R to open the valve in the tube, and thereby deposit water or oil upon the curve in the rails.

hen the operator removes his foot from the lever, the weighted arm of the rock-shaft will serve to return the parts to their normal position away from the rails and close the valve in the tube.
