ANTITELESCOPING DEVICE FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented July 27, 1915.

Application filed June 24, 1914. Serial No. 846,964.

To all whom t may concern Be it known that I, Isaac H. MILLIKEN, a citizen of the United States, residing at Aspinwall, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Antitelescoping Devices for `Railway-Cars; and I do hereby 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.

My invention relates to safety appliances for railway cars and has for its objectthe prevention'of telescoping of the cars when As is generally understood, telesco'pingk rarely occurs unless there is such a vertical shifting or displacement of the cars with respect to each other thatthe mating platforms, buffers, end sills or the like are forced out of alinement to an extent enabling them to pass or ride by or over eachother.

Accordingly, it is the object of my invention to provide simple, efficient and practical means for preventing adjacent platforms, buHers, end sills or the like from passing each other in the direction of length of the train when the cars are coupled to one another. Generally stated, this object is accomplished by providing the car coupler with inclined means-adaptedto extend under a similarly inclined portion of an adjacent car during maximum buliing stresses and to engage such portion of the adjacent car upon a relative vertical movement of the said car and coupler,` to thereby restrain and limit the vertical movements of connected cars to an extent suflicient to prevent the opposed faces of mating platforms, buifers or end sills, as the case may be, from becoming wholly disengaged and riding over or sliding past each other in the direction of length of the cars.

As my invention is conspicuously advantageous when employedfor the purpose of preventingthe telescoping of passenger cars, it has been illustrated' in the accompanying drawings in a form that 'is especially applicable to cars which are provided with buffers, since passenger cars generally are provided with buffers in addition to the yiel'dingly supported car' couplers.

In' the `drawings illustrating my invention, the scope whereof is pointed out in the ap- .ings being iny vertical section.

pended claims, Figure 1 is a view showing my invention as applied to two passenger cars, the cars being in normal coupled relation, the couplers being shown in side elevation and the buffers and platform end castview corresponding to Fig. l, but illustrating the relations assumed by the parts when the buffers and draft gears are fully compressed and in normal alinement. Fig. 3 is a view similar to Fig. 2, but showing the relations of the parts when the buers and draft gears are compressed and one car is in the position of maximum elevation with respect to the adjacent car. Fig. 4 is a plan view of the devices at the end of one of the cars, the coupler and buffer being compressed; and Fig. 5 is a view corresponding to Fig. 3, but illustrating a modiication of some of the structural details of my invention.

In the drawings, l indicates a coupler of the Master Car Builders type having a knuckle which is provided at its exposed end with an upwardly extending projection 2 that is adapted, as illustrated in Fig. 3, to

engage a corresponding portion 3 of the end casting of the opposite car platform to limit the relative vertical movements of the opposed platforms, as will be readily understood. In order to bet-ter insure the 'secure engagement of the tops of the lugs 2 of the coupler knuckles with the undersides of their respective platform end castings when the cars are shifted vertically during a collision, the upper face of each lug'y 2 and the under face of each portion 3 of the end cast ing are preferably correspondingly inclined cr beveled as shown, the inclined face of the knuckle sloping downwardly toward the knuckle-pin 4; and in order to secure an extended and even bearing of the coupler upon the appropriate face 3 of the opposed end casting, the upper face of the upper pivot lug of the coupler head may be beveled, asat 5, so as to form a continuation of the inclined face of the knuckle 2. Except as above indicated the construction ofthe car' coupler l is not of material importance` and, therefore, requires no further description.

In `both forms of construction illustrated in the drawings a buffer is slidably mounted onthe end casting of the platform. In the construction shown in Figs. l, 2, 3 and 4, in which the lower member of the end casting Fig. 2 is ak preferably extends to or approximately to the line of the front vertical face of the buffer when the latter is in its position of complete compression, the inclined surface of the upwardly extending projection 2 on the knuckle together with the inclined upper face 5 of the pivot lug of the coupler on the adjacent car are adapted to directly engage the under surface of the portion 3 of the end casting; but in Fig. 5 is shown an arrangement of parts in which the coupler is designed to engage the under surface of the buffer of an opposed car, the upward movement of the coupler being, however, resisted by the platform end casting to which is transmitted the upwardly acting forces imparted to the buffer by the coupler.

In the construction shown in Figs. 1 to il,

j inclusive, of the drawings the end casting or f sill 6a.

end member 6 of the platform is illustrated as provided with a downwardly extending projection 7 to which the usual carry-iron S for supporting the coupler is secured, such form of construction-being preferred on account of its simplicity.

The buffer 9, which is slidably mounted on the end casting or end sill member 6, is preferably provided upon its rear or inner side with a pocket 10 for the reception of a central buffer stem 11, the side walls 12 of the pocket being divergent rearwardly, as illustrated in Fig/4, so as to permit the buffer 9 to turn freely when the car is passing around a curve; and side or lateral buffer stems 13 are also preferably employed, a well known form thereof being shown in the drawing. The buffer 9 is also formed with jaws affording a recess ll into which the top member 15 of the platform end casting 6 fits, while the lower face 16 of the buer is preferably inclined to correspond to the adjacent inclined portion 3 of the end casting, such a construction, as will be appreciated from an inspection of Fig. 3 of the drawings, serving to distribute and equalize such strains as may be imparted to the end casting by the opposed coupler on the adjacent car at the time of a collision. The usual foot plate rests upon and extends between the bilder 9 and the platform end casting 6.

In the form of my invention illustrated in Fig. 5 the buffer 9gl is shown as slidably mounted on a platform end casting or end The lower face of the buer is inclined, as at 16, and is designed to come into direct engagement with the correspondingly inclined faces of the knuckle 2 and pivot lug 5 of the opposite coupler on the adjacent part. The buffer 9au is also provided with a centrally disposed, rearwardly extending armor member 17 that extends under the platform end casting 6aL in sliding engagement therewith; and for a similar purpose, namely, to yeiiciently resist upward forces delivered by the adjacent coupler on the opposed car, the buffer 9a is also preferably formed with a rearwardly extending central projection 18 which slidably lits into a corresponding opening or pocket 19 that is formed in the forward end of the end casting 6a. In this form of construction, instead of fashioning the central projection with a recess for the reception of a central buer stem, as is the case in the construction illustrated in Figs. 1, :2, 3 and l, the lug 18 is, for the salie of adding to the strength of the apparatus, preferably formed as a solid member.

In the following claims the term end sill member is employed in a generic sense, and

members which are the equivalents thereof for the purposes of this invention, such as buffers, platform end castings or like devices at the end of the car independent of the coupler.
