RAILWAY-CAR.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed December 7. 1906. Serial No. 346,820-

' To all whom it may concern:

Be it known that we, GEORGE Tnoaras MARTIN and WILLIAM HENRY DART, both of Smiths Falls, in the county of Lanark, Province of Ontario Canada, have invented certain new and useful improvements in Railway-Cars, of which the following is a specification.

Our invention relates to improvements in railway cars and the objects of our invention are to provide an improved simple strong and compact car which will not telescope or override in the event; of a collision or any other sudden change in velocity and thus save both life and property.

- This object is accomplished by forming the cars so that they will abut along planes inclined at an acute angle to the line of movement whereby any sudden impact instead of being transmitted is diverted laterally at the end of each car causing the cars in place oi telescoping to swing laterally on the track and remain intact.

An embodiment of the invention is illustrated in the accompanying specifications and drawings.

Figure l is a side elevation between two cars made in accordance with our invention and having the vestibules thereon. Fig. 2 is a horizontal sectional view through the same. Fig. 3 is a plan view of the under frame of the cars. Fig. 4 is a partially diagrammatic view illustrating the action of the cars in case of accident.

In the drawings like letters of reference indicate corres iionding parts in each figure.

Referring to Figs. 1, 2 and 3 A and B are two cars of any suitable or desirable construction provided as usual with vestibules a and b at each end thereof.

C and D are the steel underframe of the car of well known construction.

in accordance with our invention two or more of the main beams 1: and d of each frame are extended beneath the platform and joined at their ends by face plates 0 inclined at an acute angle to the direction of movement of the car that shown being substantially at fortyfive degrees. The usual type of coupling E is provided beneath the frame. As shown the two face plates 6 of adjacent cars will be parallel to each other. At the extremities of each of the platforms substantially square-shaped lateral extensions 7: and l are provided. which will support, when complete, the usual space in the vestibule to accommodate the passengers. The vestibules a and b on the cars will also be con structed with adjacent inclined face plates] and g with the opening for the passage way between the face plates f and g, but the vestibules at their outsides. m and n, will extend a distance in a direction at right angles to the line of movement of the car, but their center portion 0 will be inclined to the line of said direction and parallel with the beveled edge on the platform beneath. The portions n and 0 at right angles enable square spaces 1) and q to be provided in the vestibule on top of the extensions I: and Z. Otherwise however, their construction will be the same as that generally adapted and they will be provided with the usual exit doors h and steps i. The engine of the train may also have its end inclined.

Referring to Fig. 4 which illustrates the operation of the device 3. 4 and 5 represent a train of cars travcl ing in the direction indicated by the arrow. Should the cars meet at the point 6 an obstruction of sufficient power to suddenly reduce the velocity of the train or altogether stop it then the impact caused by the sudden stopping and reduction of velocity in the train produces a repulsive force suiiicient under ordinary conditions to crush the cars together, the platforms of each car being lifted somewhat from the track and placed over the platform of the preceding car tearing the non-resistant material of the upper part of the car and destroying both life and property. If however the cars are constructed in accordance with our invention with inclined ends then the reactive force in place of acting in this manner to cause the cars to crash together will be diverted laterally as it passes from car to car causing the end of the ar to slide along the line of least resistance which will cause the cars to leave the track and come to rest in a line more or less inclined at right angles to the track; The full and dotted lines in the drawings indicate two different positions which might be assumed by the cars in the event of stoppage. It will thus be seen that any force which would cause the cars to crush together is diverted and acts to swing the cars on the tracks into a position of safety.

It is evident that the invention might be employed with any form of car construction, the essential feature being that the adjacent ends of the cars are inclined at an acute angle to the direction of movement of the cars.

What we claim as our invention is;

In an anti-telescoping car. the combination with two cars of a plurality of beams outwardly protruding); from the center of the same, face-plates connecting the ends of the beams disposed at an angle to the direction of movement of the car. a platlform projecting laterally from the extremities of the longest beams of each car, platforms adapted to provide the free space in the vestibules for convenience in 1) age, and suitable vestibules disposed above the said platforms, the faces of the said vestibules having their center portions disposed at an acute angle to the direction of movement of the car and their outer portion at right angles thereto.

Signed at Smith's Falls. in the Province of Ontario, this 27th day of November, 1906.
