16 Claims.

This invention relates to improvements in Method of and apparatus for treating ballast and it consists of the matters hereinafter described and more particularly pointed out in the appended claims.

In the maintenance of railroad road beds, the matter of drainage is important and such drainage is affected by the cleanliness of the ballast.

Due to the trafiic conditions and certain -weather elements fine particles such as coal dust, sand, fine soil and the like are deposited upon the ballast and in time, rains and melting snow carry the sameinto the interstices between the component parts of the ballast to close said interstices. Hence, the ballast becomes clogged, caked or foul. Such foul ballast becomes sealed against drainage so that the water from rains and snows accumulates as puddlesnot only to cause tie rotting but also to promote the growth of vegeta- ;,tion, both of which conditions it is desired to 'avoid in track maintenance.

In the passage of trains over a track on such foul ballast, the rails take on a wave motion which induces an up and down tie movement,

5;,In wet weather, such tie movement acts in the manner of a pump to force water away from under the ties and then toward the ties. This action is such as to produce a mud that seals the tie ends against drainage so that track con- 301;, ditions rapidly grow worse.

To overcome such conditions for proper track maintenance, the ballast must be cleaned from time to time to insure drainage down. to subballast where it can be'carried away.

One of the objects of the present invention is toprovide an improved method of treating railway ballast which consists not only in removing shoulder or intertrack ballast preferablyfor cleaning andrelaying but also simultaneously 'therewith to break up the caked intertie end ballast at some distance inwardly of the tie ends to promote drainage.

Another object of the invention is to provide an improved method of treating railway; ballast practical and which method can be carried on as a continuous operation.

A further object of the invention is to provide 7 an apparatus whereby the improved method may be expeditiously carried out.

The above mentioned objects of the invention, as well as others, together with the many advantages thereof, will more fully appear as I pro--.

In general, the improved method includes the removal of the ballast whether along the shoulder or intertrack space, substantially down to subballastfor subsequent cleaning and. relaying. The removal of the ballast is best carried out as a continuous operation and simultaneously therewith, the caked intertie end ballast along the shoulder. or intertrack space or both has an upward'and inward pressure applied thereto, preferably vfrom a plane below the ties, which loosens said intertie end ballast, some distance inward of said tie .ends.

Referring now in detail to that embodiment of the; invention, illustrated in the drawings and especiallyto Fig. 1 thereof:

I and. 2 indicate the tracks of a double track railway. Each track includes pairs of rails 3 disposed upon associated cross ties 4 which rest upon ballast preferably of. crushed rock or stone and which in turn is laid upon a suitably graded subballast 5. The ballast is, formed to provide the shouldersB-B at the outside of each track and between said tracks is the intertrack space ballast 1. As is usual in railway construction, the ballast material is also disposed between the ties 4.

The improved apparatus whereby the method may be carried out includes a propellible vehicle here shown in the form of a car 8 having the usual wheels for travel upon the rails of the track. The outline of such a car is best shown in Figs. 2 and 3 respectively.

At each side of the car is operatively supported an excavating mechanism 9 which may be moved from its non-working or transport position on the car, to its working position upon the ballast at the shoulder and intertrack space respectively, of the railway. As the mechanisms 9 at both sides of the car are the same, a description of one will suffice for both.

Each excavator mechanism includes a pair of laterally spaced side plates l0 between which is located at the front end thereof, an upwardly and rearwardly inclined grate or screen H. At the bottom end of said grate is a shovel or plow l2 which in operation digs substantially down to the subballast 5. Associated with said grate or screen is an excavating or digging chain I3 which is driven in any suitable manner so that its bottom lap travels upwardly of the grate. This chain includes teeth It which in the operation of the chain, dig into the ballast from above and excavate successive quantities therefrom and moves the same intothe mouth or inlet of the mechanism and then along and upwardly of the grate. At the bottom front end of the mechanism is a subballast grade plow or cutter l5. When the car is moved along the track, each mechanism will remove ballast substantially down to subballast as a continuous stream or mass.

Associated with each mechanism at the front end thereof is a pair of Wings which perform several functions. These wings not only define the effective width of the mouth for each mechanism but they also serve to form a line of cleavage along the line of the tie ends. At the same time they exert a pressure upwardly and inwardly of the tie ends from below to cause a slight upheaval of the intertie end ballast. This breaks the ballast so as to loosen the same. In this condition a certain amount of the dirt or foreign matter can be washed away by the rain and drainage improved. These wings are movable inwardly or outwardly so that the line of cleavage may be made to follow the irregularities of line or lines of the tie ends.

Each wing is in the form of a vertically disposed plate l6 provided at its rear ends with bearing sleeves I! to coact with similar sleeves 18 on brackets l9 secured to the side plates of the mechanism 9, pins 29 extending through said sleeves to provide the pivotal connection between said plates and side members iii. The front end of each plate is provided with a sharpened edge 2 I, whereby it may more readily cut through the ballast.

The bottom portion 22 of each wing is offset outwardly from the top end portion 23 but is connected thereto by an inclined portion 24. When the mechanism 9 is working in the shoulder or intertrack space, the bottom edge of each wing works substantially in the plane of the grade of the subballast and this brings the inclined portion of each plate a little below the level of the bottom of the ties 4.

Each plate is provided at its top end with an outwardly extending yoke 25 by which a means may be connected to said wing for swinging the same inwardly or outwardly about its pin 20 whereby the front ends of both wings will effectively define the width of the mouth for the associated excavating mechanism. As shown herein such means is preferably a hydraulic engine 26 and each engine includes cylinders 21 having top and bottom vertically disposed trunnions 28 about midway of their ends as best shown in Fig. 1. These cylinders face in opposite direction. The trunnions of each cylinder are journalled in brackets 29 secured to a cross member 30 at the upper front ends of the side members l0|0. Each cylinder has a piston rod 3| extending through its outer end and each rod is pivotally connected at its outer end in the yoke 25 carried on the outer face of an associated wing.

A pair of conduits 33-44 is operatively connected to the opposite ends of each cylinder and lead to opposite sides of a four-way valve 35 on the car. This valve is further connected by pipes 36 with associated headers or manifolds 31 which are in turn operatively connected to suitable sources of hydraulic fluid under pressure.

When the valves for these cylinders are properly manipulated, the pistons thereof are projected or retracted to swing the wings outwardly or inwardly about their pivotal connection with the side plates so that their front edges can be made to closely follow the lines of the tie ends.

When the plug of any one or more of the valves 35 is turned to bring its ports into the off or closed position shown in dotted lines in Fig. 5, no fluid can pass through the valve and the associated piston is thus held in the desired position.

When the excavating mechanism is in working position and the said mechanism is moving through the ballast at either the shoulder or intertrack space, the operator, from a convenient position on the car, manipulates the valves 35 so as to swing the wings inwardly orroutwardly of the tie ends so that the front ends of the Wings miss the tie ends and thus follow the lines there of, it being borne in mind that this line is not a perfectly straight one as the ties are quite irregular.

As the front edge of the wings cuts through the ballast it forms .a line of cleavage that defines the sides of the excavation being made. As these wings cut through the ballast, they will direct the ballast between them inwardly toward the mouth of the excavating mechanism.

Due to the inclined part 24 of each Wing, which as before stated works in the ballast below the plane of the ties, an upward and outward pressure is produced thereby, which is manifested as a slight upheaval of the intertie end ballast so as to loosen up the same fro-m its caked condition, some distance inwardly of the tie ends. This breaks up the mud sealed condition existing in the intertie end spaces with the advantages before stated.

The ballast excavated by the mechanism 9 is preferably cleaned and then returned to the subballast so that with loosened intertie end ballast and with clean ballast on the shoulder and intertrack space, a free draining roadbed results.

The method is continuous in its operation and therefore the treating of the ballast for the purpose described is quite rapid. Hence the cost of treating ballast is relatively low and fine results are produced.

While in describing the invention, I have referred in detail to certain steps of the method and the sequence thereof, as well as to certain structure whereby the same may be carried out,
