Total/Z7, toll/0m, it may concern;

33s it knownthat I, JAMES TL'ANDREW, a

citi'zen of the United States, I residing at Montgomery, inthe county of Montgomery and State of Alabama, have invented certain new and useful Improvements in'Safety Appliances for Railroad Cars; and 'I do hereby .declare the following to: be a full, clear, and

exact description of the invention, such as- 0 will enable others skilled in the art towhich it appertains to make and use the same.

My invention relates to improvements in safety appliances for railroad-cars; and the object of my inventionisito provide means I 5 whereby derailment ,of a train, with itsaccompanying destructive effects, "shall be rendered practically impossible.

My invention is applicable not only to rail"- road-cars, but-also .to electric cars of all de- 29 scriptions and to locomotives.

Other objects will appear "in the description. w 1' With this object in view my invention consists in the construction and combinations'of 2 5' parts, as hereinafter described and claimed.

' In the accompanying drawings,'Fig'ure 1 is a side elevation of the ordinary passengertruck, showing my invention applied thereto. Fig. 2 is an end view of the same. Fig. 3 is 0 an enlarged View, partly in section, showing my invention in actual use lifting one of, the car-wheels. Fig. 4 is across-section thereof on the line 4 4 of Fig. 3.

tive view of one form of my improved shoe.

brake. Fig. 7 is a top plan view 'ofthe same. Fig. 8 is a perspective view of the inner sup portin -brace. Fig. 9 is a perspective View o o f the supporting-bracket introduced into the journal-box. F ig. 10 is a -siidegelevation ofa modified form ofmy inventions; .Figfll I is a longitudinal sections-lot said? modified form, and Fig. 12 is fa cross-section of the same.

' .In th'edrawin s, a represents an ordinary passenger-truck, avmg the usual side beams, journal-boxes, sprlngs, &c.,. which need no further. description. Underneath each j our- 5o rial-box two movable shoesfsuch' as bland c,

are located, there being therefore eight of Fig. 5 is aperspec-- may be easily applied to the existing trucks without any alteration and with very slight expense. Said shoes are shown in perspective. in Fig. 5, and each of them consists of a camshaped portion d, provided with a rounded lower edge e and rounded ends, such as f. It is also provided with'a flange g, located on the same side'of the car as the corresponding flange on the car-wheel. The in nershoe, such as 0, has a flange, such as h,

extending the complete lcngthof the shoe and of practically the same depth throughout, while the flange on the outer shoe practically disappears at the center and enlarges near the ends, as shown in Fig. 3. The reasonfor spread track the outer shoe-to fall upon the rail when the wheel runs ed and to support the car, the shoe being then thrown up into the position shown in Fig. 3, thus bringing the wheel back into position on the rail after the spread portion ofthe track has passed of two castings, the main portion (1 having an these shoes to every truck. These shoes having the flange on the outer shoe 'constructed inthis way is "to allow in case of The shoe is constructed, as shown in Fig. 5,

upwardlyrprojecting ear-i, a depression 1 for the reception of the pivot-pin, and holes m for the reception of the. springs hereinafter referred to- The other piece of the shoe con- ,sists of an upwardly-extending perforated ear '0 1 and sidewise-extending portions p, which fit into corresponding depressions cut in the'top of theshoe. The detachable piece is heldin place by means of bolts 1*. In Fig.

. 5 the detachable piece is shown on the inside of thej hoe; but it could be placedon the outside of the shoe, if preferred. Theshoes are held in position by means of, a supplemental beam is. (Shown in Figs.- 1 and 3.)

This is attached by bolts t to the regular equalizing-framed the truck and to the out-' side beams 14 and also by boltsthrough the pedestals v and the frame of the truck. From these beams, if desired to strengthen the construction, a collar may extend from beams 8 completely around the journal-boxes. These beams-s are provided with'a downward rojection w for the reception of the pivot-pin x, which runs through theears i and 0 on the shoe. The pin a: is welded to the beam 'i,- i

' thereby forming an integral part thereof." In each of the holes 'm-is fastened, by means at its upper end to a yoke of a pin, a tension-spring y,

of the car will rock the shoe back into-the pof sition shown in Fig. 3, which will have the ef-' fect .of automatically raising the car-wheel and truck out of'harm s way and at the-same I truck-Wheels; and "four inside.

, The manner of mounting the inner att st 'willnext bedescribed.

To the main frame .of the-truck are :at

tached depending beams 11 and a dependlng" center beam 12, to which beam's'is attached an (Shown in detail in, Fig. 8.)]? This constructionis the same at'both en'dsof the truck and "is used for the purpose'ofliftingjthe car out of harms way, as shown by theconnections with the shoes 0.

The. operation is as follows: Supposing that the train leavestthe track'forany'reaf son-' as for example, a .br'oken flangegon one of. the car-wheels, especially" while traveling around a curve either thegrightorgto the i spread track, 'or on il; or of,. a misplaced switch -in. this'caseks'onie part-of the truck will drop s1ightly; and one or fmore .of the}, 'strike "'the;rail.

For example, if the train should be derailed and moved to the right from the position shown in Fig. 2 the shoe 0 would engage one of the l rails and the opposite shoe 1) would engage the other of the rails and immediately lift the wheels above the rails and apply the brakes I automatically, as previously described, and the shoes I) -and 0 would slide along the rails, assisting the train to come to stop.

While I have thus described my invention, l

I wish it to be particularly understood that I f 'donot limit myself to the exact details l shown and described, as these might be va- 1 ried widely without departin from the spirit of my invention, the essence of which j is that in case of derailment-of any part of E the train the derailed portion is lifted out of harms way, and the train is automatically stopped before any appreciable harm can be done either to-the track or to the rollingstock.
