JAMES T. ANDREW, ()l" Blf IITGCFXlEI-lY, ALABAMA;

SAFETY APPLIANCE FOR EAELWAYS.

' To all whom it may concern:

Be it known that I, Jam-2s T. lxmtnw, a citizen of theLnited States, residing at Montgomery, in the county of- .\Iontgomer v and htate of Alabama. have invented certain new and useful improvements in Safety Appliances for Railways; and I do hereby 'declare the following to be a full, clear, and-exact description of the inventiomsuchfs will enable j others skilled in the'art to which it appertains to make and use the same.

My invention relates to improvements in safety appliances for rail oad cars. and the object o my invention is to provid a means whereby the derailment-of a train, with the injurious effects arising therefrom, shall be rendered practically impossible, this application being: in the nature of an improvement upon my former applications Serial No. 349,727, filed September 2751906. and Serial X0. 389,562, tiled August 21-, 1907.

A further object of my invention is to simplify and to cheapen the structure heretofore applied to existing railroad equipments, and at the same time to renderthe same. more reflective in action.

A further object of my invention is to provide a means by which the operation of the air brake system is rendered more certain in the case of a derailment, and a signal is given.

To these ends my invention consists in the novel combination of parts more fully hcreinafter described and pzn-ticularly pointed out in the claims. I

journal boxes. :3, the ordinary pedestals of a car truck: and 6 the e jpializer beams.

Secured t the journal box by means of the straps T. is the safety frame 5. which is scrured to the equalizer beam by the bolts 9,

and to the pedestals by'the slip be i0. in tlussalcty frame 8. is carrie the ='-a5tyroller 11, the. frame being p'rm'ided with downwardly depending curved projections 12, forming an open cylinder bearing: for the reception of t "rid roller, thereby forming in reality a c .ical safety frame. The roller 11 is provid .i on its inner end with an integral collar 1 "Yfl on its outer end with a removable collar 14. there being a cotter pin 15. passing through the end of the roller 11, to hold the collar l-i in place.

ln'assembling these parts, the roller is placed in the open cylinder hearing, as shown, before the safety frame is secured to the journal box, pedestals and equalize beam, and the cotter pin p ed through the hole in the end of the roller provided for that purpose. 'lien in place this roller 'will stand about three inches above. the top of the rail. and the open cylinder being larger than said roller. will allow the same to rise about; one half an inch shouid contact with the rail ocrur. any: for a pn pose to be described hereinafter.

On the car axle 2 between the wheels 3, I

place a slcex'e 13 madein halves. provided with lugs 19. taperedfjournal bearings 20, and with shoulders 21, all as shown. Outliebearings 20, are the safety wheels 22, hating double flanges 23 and 24. These wheels may be either split wheels. or made in one piece. In either case the flanges 23 are more tapered than the flanges 24, for a purpose that will presently appear. The lugs 19 serve to secure the halves of the sleeve toaxle ()rer eafth sleeye 1 scoured two of my safety beam supports '25, and these supports are provided with the straps 26; ens

'gether. and to make the, same rigid with the circling said sleeve and having the. bolts 27 upper end of these beam supports 25 is secured to the front cross beam 29 of the truck; and the rear upper end is secured to the cen ter bolster trialling-3t) of the truck by means of a safety band 3t, which encircles the main truck spring casings 32, and their connections, as clearly shown in Fig. 6.

50 contacting with the tops of the rails.

Extending between the journal box 4 and The wheel 3, is a plunger rod 35, passing through guides 36. This rod. at the upper end actuates a phuiger 37 which controls a 5 valve 37 in the casing 33, on the end of the pipe 39, which connects with the train line of the air piping 40, which operates the brakes. This piping 40 is also provided with the valve levers -11, having the connections -12, with the levers 43, pivoted at 44 to the car body, and extending into the path of the wheels 22 for a purpose that will be presently explained. The safety and sign allevers 43, are also provided with the connections 15 leading to the lever 46 of the engineers and conductor's whistle signal 47, having the well known pipe connection 48 with the cab of the engine.

In the modification shown in Fig. 5, in-

2b stead of employing the straps 7, as illustrated in Fig. 2, for securing my cylindrical safety frame. to the journal box, 1 cast the same integral with said journal box as shown. That is to say. the lower bearing 50, in mv 5 safety frame for the car journal, which comes into play 111 case of an accident, is cast integral with the box 51, as shown.

In both forms of my invention the lower end of the rod is provided with a suit ably 39 shaped shoe 49, with which the collar 13 of the roller 11 contacts.

The operation of my safety appliance is as follows z-Vfhen the flange of a wheel 3. rises "to cross a rail 1, during a derailment of the 5 train, the safety roller 11 on the one side and the safety wheel 2'3 on the other, of uccessit y hkewiserises; and a roller on one side of the truck and a wheel 22 on the other side of the truck moves toward the rails, and of neces- 4o slty contacts therewith when the flanges ot the wheel 3 have crossed the rails and fall onof the rails before the flanges of the wheels 3 reach the spikes or ties, so that the train for the time bem will be supported by reason of one of the rollers 11, on one side, and one of the wheels 22 on the other side of the truck In the meantime, one of the safety brake and signal levers 43, which are pivoted. to the car body, is struck by one of the wheels 22, as it is carfried to one side or the other of the track. and

: the air brakes are applied, and the engineer's whistle blown through the connections shown. In addition to this. since the roller 11 has a vertical motion in its open cylinder bearing formed by the rejections 12 it will.

a when itoontacts with t to top of the rail, rise in-said bearing and strike the shoe on, the rod 35, thereby opening the valve37andatfording a continuous additional means for apply- 0 the brakes.

he flanges 23 of the wheels 22 are made ,rious sizes, and if it were necessa order to render more certain the engagementof the treads of the wheels 22 with the top of the rail, as is apparent from the drawings, In other words, by beveling the flange 23, it is caused. when it strikes the outer edge of the rail, to exert a wedging action, and to insure the throwing of the flange of the wheel 3 sufficiently outward to prevent said latter flange from shcaving the bolts and spikes of the track with which itmight otherwise come in contact. An additional advantage in beveling said flange 23, is found in the fact that it forces the truck sufficiently to one side to insure that the roller 11 on the opposite side of the truck will be thrown far enough for its flange 13 to clear the rail and to bring the tread of said roller firmly into contact with the upper surface of said rail.

An important feature of my invention re;- sides in the construction embodying the sleeve 18; for axles now in use are of vato provide each of the same with journa s for my safety wheels, not only would the time eonsumed be great, but the cost would also be an important item. By employing my sleeve 18, however, I am enabled at any time to apply it to any existing axle. by the simple expedient of employing liners or washers to make the sleeve fit said axle, and can at once secure it in place by the fastening means shown. After the sleeve is once in place, it furthermore serves to hold the two arts of the axle together should the same ecome broken, and thereby obviate a most fruitful outer journal breaks. thereby preventing any portion of the truck from dropping to the and in place should it break. the above. as snown in Fig. 6, the two inner ends of each pair of safety beams 25, are joined by the safety bands 251, which encircle the main truck spring casings 32. as above stated, and this structure in-casc of an accident to any portion of the spring equipment prevents the same from coming down to the track. and consequently obviates another fruitful cause of wrecks atthe present day. Furthermore, by providing the additional safety brake ap lynig means 35. 37 etc., and the signal sounriitw means 45, 46 etc., I have, in case of an accident, two means for autotr'ack; as well as serving to hold the axle up In additton'toi in .rnals on their-ends; safety matically setting the brakes, and, also, a third means of notifying the engineer.
