Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed- June 7, 1920. SerialNo. 387,14 4.

To all whom it'may concern:

Be it known that l, SYDNEY Ann-run P. CLARKE, a subject of the King of Great Britain, and resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improve ments in Car-Derailers, described in the following specification and illustrated in the accompanying drawings, that form part of the same.

The principal objects of the invention are, to avoid cumulative accidents on railways through the disobeying of orders and rules in passing danger signals, and to provide a positive means of stopping a train at a definite point by de-railing.

A further and important object is to devise a derailer which may be readily handled by a single individual and readily placed or removed instantaneously without the use of tools. 7

The principal feature of the invention consists in the novel construction of an obstructing member adapted to lift the wheel of a car or locomotive from the rail and carry it clear of the same whereby said member is readily secured to the rail.

In the drawings, Figure 1 is a perspective view of the derailer shown in place upon a rail.

Fig. 2 is a plan view.

Fig. 8 is an end elevational view showing the section of the rail.

It is well known that many serious accidents on railroads are of a cumulative nature. A minor accident to one train stalling or holding it up and protective signals being disobeyed by a following train cause a collision. In order to positively protect a stalled train from collision a derailing device is provided in the form of a unitary metal member which may be instantly placed upon the track and is of such a nature that it may be very easily handled by the traimnan.

The device consists of a unitary block of metal 1 formed with a groove 2 in the underside adapted to receive the head of the rail. The end 3 slopes upwardly from the thin edge e to point 5 where the block extends laterally from one side and is provided with a deep sloping groove 6 into which the wheel flange of the locomotive or car is guided. The outer side of the groove is flanked by a very strong flange 7 which projects upwardly considerably above the top of the flat portion 1 of the block and said flange extends diagonally across the top of the block to the extremity opposite the end 3. i

The front sloping wheel bringing the groove 6 and the wheel flange then engaging theflange 7 is guided diagonally across the top of the block until it is clear of the rail and drops oil on the far side.

The principal feature of this block rests in its manner of being secured to the rail. This is accomplished by means of a leg 8 which extends downwardly at one side of the ball of the rail and is turned inwardly under the ball. A foot 9 formed on the lower end of the lug fits snugly against the web of the rail and is provided with a toe 10 extending forwardly. The toe 10 is of a wedge formation adapted to be inserted between the hollow back of the angle bar 11 and the rail web 12 and the upper edge of the toe portion is sloped to the front end so that when the block is laid upon the ball of the rail and pushed into position the foot 9 will be drawn tightly into place by the angle bar wheel flange into the end lifts the tire of the 4 thus holding the block 1 snugly to the ball of the rail so that it cannot become displaced.

.lhe effect of the block in use is that the wheel of a car or locomotive strikes the front end and if it is not previously driven tightly into position the effect of the striking of the same by the wheel will only drive it home tight so that it will fit snugly to the rail. The wheel then mounts the block and is guided oil the rail by the flange .7. The device may be readily removed from a rail after it has been placed thereon by simply knocking it backward to free the foot from under the angle bar.

The device is of a single piece of metal and requires no tools to place it in position. It is strong and effective in accomplishing the desired result and as it may be handily carried under the arm it may be placed in every trainmans equipment so that he may carry the same readily along with his signal case, and should be governed by rule 99 of the standard code and placed on the rail 300 from rear of the standing train on the engineers side of approaching train.

l Vhat I claim as my invention is 1. A. car derailer, comprising, a metal block adapted to lit the head of a rail and shaped to liftthe wheel and guide it over the rail head and having a depending member on one side adapted to interlock'with an obstruction on the web of the rail to hold it securely from longitudinal displacement;

2. A car derailer, comprising, a unitary metal block having a groove 1n the underside to fit the rail head and a portion projecting to one side and formed with an upwardly inclined groove and a flange at the outer side, said flange extending diagonally across the rail head to direct the wheel flange thereover, and means on the opposite side adapted to secure the block in position. 7 r a V 3. A car derailer comprising, a unitary metal block having a groove in the underside adapted to fit the rail head and a guide groove on the upperside atthe inward side thereof and a flange flanking the outer side I of the latter groove and extending diagonally across the block, and a leg extending downwardly from the outer side of the block and having a foot portion adapted to engage the web of the rail and'to fit between said web and the fishplate.
