To all whom 'it may-concern:

United Statesfresiding in New York,.county of New York` and State of.New York, have made a certain new.

Be it known that I, FRANK HED'LEY, a, citizen of the and useful Invention in Attachments for Preventing ".lelescoping ofCars, .The invention relates to attachments for preventing- I Athe telescoping of cars in collision 'or other accidents.

The object-of the invention is to provide an attachment which is simple in construction, economical in manufacture and efficient operation and which can bereadilyand easily applied to the ends ci cars or oiv A cer platforms whereby the telcscoping of the cars in caseof collision or other accidents incident to their opi f eration is guarded against. l ,M A further object of thc invention is the provision of simple, inexpensive and efiicientineans for preventing the relative vertical movement ot adjacent ends of cars,

in case-of collision or similar accident, and which is u sually the antecedent of destructive, disastrous, and irequentlyatal, telescoping of the cars.

. A further object is to provide means for resisting the relative vertical movements of theiadjacet ends of cars, in case o collision or accident, but which leaves such ends free for vertical play in the ordinary operation ofthe cars under normal conditions.

A further object is to provide means for resisting any tendency of the cars to turn over'sidewisc in case oi collision or other accident, without interfering with the ',-brdinary movements and vibrations of the cars while in jOperation under normal conditions.

l Other objects of the invention will appear more fully hereinafter. n 4

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as be more fully hereinafter set forth,

as shown in theraccompanying drawing, and finally pointed out in the appended claims. A .Referring to the accompanying drawing, and tothe various views and referencev sign appearing thereon:

Figure 1 is a broken view in top plan of a car platform l u showing the application thereto of anattachrnent embodying the principles of my invention. Fig.4 2 is a -ront end view of thesame, 3 is abroken view in section on the lifne 3, 3,l'Fig. 41, looking in the direction of the arrows. v*'i'Fig. 4 is'a view similar to Fig. 3, on the 4line 4, 4, Fig. `2loolring in 'the direction of thc arrows.

. Figs. 5 and 6 are views similar to Fig; 2, the end broken off, showing slightly moditied forms of attachment emrbodying' the principles of my invention. Fig. 7 vis a The same part is designated by the samereeIenc'e' sign wherever it occurs throughout the several views- In case of collision or other accident of street or railway cars or trains, causing thecnds oi the cars to be brought together with violent force, the danger is incurred of the cars telescoping the one upon the other, causing damage or destruction to the cars, andfire-` quently injury and death to the occupants othe cars. In order to avoid the destruction and dangerous effects of telescoping of the cars, it is a common practice to provide the under framing of the car bodies with sills or beams extending longitudinally. of the cars, so that the strain imposed by the collision impact may be taken thereby, and, in the case of passenger cars, the plat` 7U forms are constructed with a view to abut edgewise against each other in case oi collision, to resist the telescoping tendency. Experience has shown, however, that the force of the impact of the cars in colliding, fre'- quently causes thev end of one or the other ci the cars to be moved vertically, upper dwn, a distance suicient tor the platforms to pass orto overlap the one upon or beneath the other, or the endwisc extending sills or beams to be moved out of longitudinal alinement with cach other. This condition is also contributed to by the truck wheels ci one 'or the other of` the cars leaving the track rails, or the tracks or axles becoming broken or smashed by the impact of `the collision, thereby causing the end of the car to be lowered relative tothe proximate end ofthe adjacent car. In such cases, with 85 nothing to resist the force oi theimpact except the frail framing of the car vestibules, or of the ends of the csr. bodies, the ends of thc cars` climb theone upon the other, and crash into each other endwise, causing the dangerous 'and 4dir-iastrous telescoping thereof. It has 90 been proposed to avoid these results and effects by providing' the end of each car platformwith means to mechanically engage the proximate platform of the adjacent car. Such method, however, is impractica-4 ble and objectionable for the reason that thereby the cars are not permitted to-move freely 'with relation to and' independentlyof each other, in `the natural and normal operation of the train, and it is essential that this i'ree independent movement of the cars vertically be provided for, and in turning sharp curves'the engag- 100 ing means, referred to, prevent the necessary flexibility of the train for relative lateral movement of thc cars, or else they .become disengaged and hence are not at all times' effective for the accomplishment of their lobjects and purposcs Moreover, by maintaining an cngagel ment between the adjacent platforms of cars, which tend to resist the relative vertical play Toi the car ends `under the iniuenceoi the swaying movements o the car body operating under normal conditions, the'constant strains of such movements of the one car, and the- 1.10 load imposed thereby, are distributed to the platform' of the adjacent car,'thereby causing .the thereof v to be rapidly destroyed or injured. Again, in case of collision, it frequently happens that the force of impact,

even when' telescoping is avoided, causes the one car or the other to careen sidewise in a tendency to turn over. i

t is among the special purposes oi my present invention to provide means which are exceedingly simple and easily applied wherein the free vertical and side- Wise play of the cars in the normal operation thereof is not interfered With, but Which, in case of collision or other accident causing the ends of the ears tocome t0- gether forcibly, and creating a tendency for the ends ofthe one car to slip or ride vertically past the adjacent end' of the other car, will cause-the ends of the cars, or ofthe ca-r platforms, yto become interlocked, thereby not only holding the carbody sills or platform ends in position 'to receive and resist the force of the impact, and, hence, preventing telescoping, but also resisting nany tendency of one or the other of the cars turning over sidewise.

In carrying out my invention I provide the ends of each car, or the ends of the car platforms, with a casting, forging, or plate, having bearing surfaces against which yworks corresponding surfaces of a similarly constructed and arrangedkcasting, forging or plate, on the proximate end -of'the adjacent car or platform, in the norma-l operation of the cars, each casting, forging or plate, having recesses or seats and ribs o r projections adapted to respectively receive or to be received in corresponding ribs or projections and seats or recesses in the adjacent casting, forging or plate, in case of collision, when a s ufllcient relative vertical displacement of the car ends occurs, whereby the carends become interlocked and held and maintained in such'relative flush w,ith the facing E, of the platform end. The nt` tachment is formed with the outwardly presenting ribs or. projections F, having the intermediate seats or recesses G. The outer surfaces H, of the ribs form vertical bearing surfaces against which Work the corresponding surfaces of the ribs or projections of the attachment on the end of the platform of the adjacent car, in the normal operation of the cars, leaving each car end free for vertical as well as sidevvise motion. In case of collision, however, and a consequent tendency of the ends of the platforms to ride up over the other thereby carrying the surfaces `l-l out of alinernent, the ribs or projections F, of the one attachment are forced into the seats or recesses G, of thc` other, thereby causing the platform ends to become interlocked, and hence maintaining such platforms in such relative positions as to re- .Ccive the force of the collidinglinpact, and hence preventing the tolescoping of the cars, while at the saine time resisting the tendency of one or the other of the cars turning over sidewisc. The ribs or projections F, and the seats or depressions G, extend longitudinally of the attachmenthand, if desired, and in lorder to facilitate sense? the entrance of the ribs or projections into the seats or depressions, said ribs or projections may be formed with anoutward taper, as shown. 'lhe castings, platos or forgings C, may be secured in place'in any suitable or convenient manner, as, for instance, by bolts .lY

Instead ofthe ribsextending the entire length of the attachment, one or more of them maybe interrupted as indicated at F, in Fig. 5, and F2, in Fig. (l. l do vnot desire, therefore,-to be limited or restricted in this respect, noris my invention to be limited or restricted to .the nunner of the ribs or projections, nor to their relative arrangement. For instance, in Figs. 2, 3, fi, o and 6, three rows of ribs and two rows of seats are cmployed, while in Fig. 7, four rows of ribs and three rows of seats or depressions are employed.

lt is obvious that my invention may be embodied in other forms and arrangements without departure from its spirit and scope, the essential feature being theI provision of castings, iorgings orplatcs on the ends of cars or car platforms which present vertically extending bearing surfaces to each other in the normal L peration of the cars, permitting free vertical and lateral play or movement of the cars, but having ribs and' seats or other engaging means adapted to interlock or engage with each other in case of collision when there is any tendency of the ends of the cars or platforms to slide vertically upon each other a distance sufficient for the ribs or projections of one attachment to be brought imo register with the seats or projections of the other opposed attachment, thereby holding the ends of the platforms, or the longitudinally extending frame sills or beams, in alinement with each other and hencel preucnting the telescopingof the ends of the cars, the one upon the other, at the same time resisting any tendency of the one car or the other overturning sidewise.

In the case of freight or other cars which are unprovided with platforms, safety attachments embodyingrl my invention may be readily applied to the ends of the deadwoods or bumpers with which the ends of such cars are usually provided, as indicated at l, Fig. 8, or the castings or forgings may themselves constitute and perform the function of deadwoods or bumpers, being suitably secured to the end-sills or other convenient part of the carbody.

In using the term plate ll desire to include thereby a forging, casting or other suitable or convenient form of l plate.

, Having now set forth' thc object and nature of my invention and variousforms and practical embodiments thereof, what l claim as new and useful, and of my own invention, and desire to secure by Letters Patent ,isz-e 1. An attachment adapted to be secured tothe ond of o cui' or car platform,` und having ribs or projections und i seats or depressions in the outer suri'uce thereof, the ends of the ribs or projections presenting vertical hearing nprfaces.

2. An attachment adapted to be secured to the end of 'n ciii or car platform, and having outwardly extending ribs or projections, and intermediate seats or recesses in the .outer surface thereof, the ends of the ribs or projections presenting vertical bearing surfaces, said ribs or projec-l ment adapted to be secured 'ln said recess, and having ribs und seats in the outer face thereof. l

5. The combination with a car and its platform, of an attachment adapted to be secured to the end of said {Siatform, said attachment having ribs and seats fox-ined in the outer face thereof, the louter edges of the ribs presenting vertical bearing surfaces.

6. An attachment edapted to b secured'to the end of a car or caplatform, and having ribs or projections and 5 seats or depressions formed therein, said ribs or projections 10 ieing outivdiy tapering. i

In testimony whereof'l have signed my name to this speciiication, in the presence of two subscribing witnesses',v on this 6th day of December, A. D. 1906.
