APPARATUS FOR CLEARING THE RAILS OF RAILWAYS, 80G.

SPECIFICATION forming part of Letters Patent N 0. 442,995, dated December 16 1890. Application filed October 6, 1890. Serial No. 367,261. (No model.) Patentedin England March 12, 1890, No. 3,906.

To aZZ whom it may concern.-

Be it known that we, GEORGE NOBES, sanitary engineer, a subject of the Queen of Great Britain, residing at 226 High Street, Harlesden, Middlesex, England, and RICHARD HENRY JACKSON, wine and spirit merchant and dealer in beer, a subject of the Queen of Great Britain,residing at 128 Elgin Avenue, Paddington, Middlesex, England, have invented an Improved Apparatus for Clearing the Rails of Railways and Tram ways, (for which we have Obtained a patent in Great Britain, No. 3,906, bearing date March 12, 1890,) of which the following is a specification.

This invention has for its object to provide anovel, simple, efficient, and economical mechanism for clearing railway-tracks of obstructions, such as stones, mud, snow, and the like.

To accomplish this object our invention involves the features of construction, the combination or arrangement of devices, and the principles of operation hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 is an elevation, partly in section, showing the invention applied to a tram-car. Fig. 2 is a section of the same at right angles to Fig. 1. Fig. 3 is an elevation showing the both cylinders c and cl.

position of the pivoted arm when met by a fixed obstruction.

a is one of the rails.

Z) is the bottom frame of the car in section.

0 is a fixed cylinder bolted to the car.

(I is a sliding cylinder fitting the fixed cylinder telescopically.

e is a frame fixed to the cylinder d.

f is the pivoted arm, secured to the frame 6 by the pivot g.

f is a cam attached to or formed in one with the arm f.

his aframe in which the cam f is confined, the lower edge of the cam or some part thereof being always in contact with the lower bar h of the frame It. The frame h is attached to the lower end of arod 7c,which extends through The upper end of the rod 713 has an eye, to which a chain is attached.

m is a lever, and n is a hook by which the rod k, cylinder cl, frames 6 7t, and arm f may be raised when not in use or for clearing ob structions.

0 is a spring traversing the cylinders c and d and pressing the cylinder cl downward.

p is another spring with smaller coils.

r is a screw-nut fitted to the rod k, whereby the power of the spring 19 is exerted upon the rod in an upward direction, and whereby the lower bar 72. of the frame It is caused to press the cam f in an upward direction, tending to restore to and retain the arm f in a vertical position.

When the rod It is raised by the lever m, the spring 0 yields and allows the cylinder d to rise inside the cylinder 0, thus raising the arm f quite clear of the rails.

The lower end of the pivoted arm f is provided with a head shaped to conform to the upper surface of the rails which are to be cleared. For tramways the head on the lower end of the arm is formed with a projection to enter the groove and a horizontal surface to scrape the top of the rail; but for railways the head on the lower end of the arm will be shaped to fit the tread of the rail.

ln fitting tramway-cars two scrapers may be used, placed within the wheel-base; but in some cases four may be fitted, justoutside the wheel-base, as preferred.

In fitting locomotive-engines and other railway rolling-stock the invention is fixed to any convenient parts of the framing, so as to clear the rails in front of the train.

1. The combination, in a track-clearer, of upper and lower telescopic cylinders, a spring acting to move the lower cylinder downward, a frame carried by the lower cylinder, a pendent rail-clearer arm pivoted to the frame, and lever mechanism for raising the arm, frame, andlower cylinder, substantially as described.

2. The combination, in a track-clearer, of

means for raising the cylinder which carries the frame and its clearer-arm, substantially I 5 as described.

Dated this 30th day of July, 1890.
