To all whom it mag concern:

of the- King of Norway, and residing at E'dgewoocl Park, in the county of Allegheny and State of Pennsylvania, United States of America, have invented certain new-and useful Improvements in Apparatus for the Con-' trol of Railway Cars or Trains,of which the following is a specification.

.My invention relates to apparatus for the control of railway cars or trains. Y I will describe one form of apparatus embodying my invention, and their point out the novel featuresthereof'in claims.

my co-pending application filed December 18', 1911, Serial No. 666,394.

In the accompanying drawings, Figure 1 is" a view showing in side elevation a-portion of a railway car having applied theret oneformof controlling apparatus embodying my invention. Fig. 2 is a view showing inend elevation the car and apparatus shown in Fig. 1-. Fig. 3 is a View showing on a larger scale a portion of the apparatus shown in the preceding views. Similar reference characters refer to simi-- lar parts in each of the several views.

Referring, to the drawings, 10 designates a railway car: This'car is equipped with-"a fluid pressure braking system comprising as usual a brake pipe 47 It is understood that a reduction of pressure in this brake pipe causes an application of the brakes.

Connected with the brake pipe 47 by means of a pipe 12 is a valve device 11. This valve device may be of any suitable type, which, when opened, remains open until the" pressure in the brake pipe 47 falls to a certain value. One form of valve device of this character is shown and described in my copending application, Serial No. 666,394, filed December 18, 1911, of which the present application is a division. This valve device 11 is operated by means of a tripping device 13 when the tripping device is actuated by a stop arm 14, as hereinafter explained; the tripping device is illustrated on a larger scale in Fig. 3. The stop arm 14 is located adjacent the trackway and is arranged to be moved into and out of position for actuating the trippingdevice 13. As here shown, this stop arm is pivoted to a railway signal sema- Minis-suspended from the blade 16 of the semaphore by means of afiexible connection 17 such-as a chain. The stop arm is prefer-j ably of flexible material to perm-it bending Patented J uly 28,1914.-. 1 Originalapplicatiom filed; December 18-, 1911,! Serial No. 6681394: Divided! and this application'fild March in a vertical plane. The semaphore here.

shown isof the upper'quadrant type; when the semaphore is in the horizontal: or

dangerposi tion the stop 14 is. in position to actuate the tripping deviceya-ndwhen the semaphore moves upwardly to caution or clear" position, theystop' arm is moved? upwa-rdly out ofjposition for engagement with ppiing'device. i The present application is a division of The valve device 11 is operated by means of a shaft which is mounted to oscillate 1n--'bearingscarriedi-n a shaft housing 38,-

which housing is mounted in the inclos'ing casing of the valve device 11. Rigidly se cured to the shaft 37 at its outer end by meansiof a pin 37 isian' arm- 39 (see Fig. 3) which I will hereinafter term a trip-arm,

andwhiclris arranged to be operated" by the 1 stop arni 14 Referring-particularly to Fig.

3, it will 'beseen that the end ofthe housing38 is slit and unr'oll'ed, forming a tongue 40 which is located over the trip arm-391 Rigidly secured to-this tongue by means of rivets is a plate 41 of comparatively stiff, material such as-xcold rolled-steel, also a strip 42, 'of resilient material preferably" 7 The end of strip '42pr'esses downwardly upon the tri'p-arm 39, thereby biasing thel'a'tter toward ablock'44 f Secured to the outerend of plate"4-1 isa strip" spring steel.

43 of resilient material, alsopreferably of spring steel, which strip bears againstthe' end: ofzthehonsi ng 38 as shown. This strip 43 preferably is providedwith an extension 43 which passes between the trip arm 39 and the block 44. This extension 43 protects the arm 39 from direct blows of arm 14, but exerts no, pressure on the trip arm 39. Mounted on the vehicle 10 are two inclined surfaces 45 and 46 facing respectively I toward and away fromthe direction of nor- A I mal movement of the vehicle. The block 44 is fixed on the inclined surface 45. These surfaces are so arranged that the strips 42 and 43 and the trip arm 39 all cross the inclined surface 45 and pass below surface 46. Assume now that the vehicle 10 is moving in thedirection indicated by the arrows in Figs. 1 and 3, and that it approaches a stop arm 14 in the operative position. If the relative positions of the vehicle and the stop arm are correct, the stop arm will be struck by the strip extension 43 and will pass between this strip and the inclined face 45, thereby raising this strip from the block 44. The strip 43 in turn raises trip arm 39 thereby turning the shaft 37 and operating the valve device 11. If the relative positions of the vehicle and the stop arm are such that the stop arm is not struck first by the extension 43*, then the arm will be engaged by either the strip 43 or the inclined plane 45 and will be guided by one or the other toward the strip 43 After the strip 43 passes the stop arm 14, this strip will spring back against the block 44, and the trip arm will be moved back against this strip by gravity and by the action of the spring strip 42. The purpose of the inclined surfaces 45 and 43 1s to compensate for the vertical motion of the vehicle and for any irregularity in the position of the stop arm 14. It will be seen that if the vehicle moves in the direction opposite to that indicated by the arrow in Fig. l and passes a stop arm 14 in operative position, the stop arm will ride upwardly on inclined surface 46 and also on the inclined plane formed by strip 42 and plate 41, and will, therefore, not move trip arm 39.

Although I have herein shown and de scribed only one form of apparatus embodying my invention, it is understood that various modifications may be made therein within the scope of the appended claims without departing from the spirit and scope of my invention.

Having thus described my invention, what I claim is: v

1. In combination, a railway vehicle, a trip arm mounted upon the vehicle, means on the vehicle adapted to be operated by the trip arm, a stop arm mounted adjacent the trackway to operate the trip arm, an inclined surface carried by the vehicle for guiding the stop arm into position for operation of the trip arm when the vehicle moves in one direction, and another inclined surface carried by the vehicle for guiding the stop arm out of position for operation of the trip arm when the vehicle moves in the other direction.

2. In combination, a railway vehicle, a trip arm mounted upon the vehicle,means on the vehicle adapted to be operated by said trip arm, a stop arm mounted adjacent the trackway to operate the trip arm, two intersecting inclined surfaces mounted on the vehicle with their acute angle opening toward thedirection of trafiic for guiding the stop arm into position to operate the trip arm when the vehicle moves in one direction, and a third inclined surface mounted upon the vehicle for guiding the stop arm out of position to operate the trip arm when the vehicle moves in the other direction.

3. In combination, a railway vehicle, two members mounted thereon to form anacute angle opening in the normal direction of movement of the vehicle, one of which members is fixed and the other movable, a stop arm mounted adjacent the trackway and adapted to pass between said members thereby moving the movable member, and means on the vehicle operated by said movable member.

4. In combination, a railway vehicle, a trip arm mounted on the vehicle, means on the vehicle controlled by said arm, a stop arm mounted adjacent the trackway, means on the vehicle for guiding the stop arm into position for operatlon of the trip arm when the vehicle moves in one direction, and

means on the vehicle for guiding the stop arm out of position for operation of the trip arm when the vehicle moves in the other direction.

In witness whereof, I aflix my signature in presence of two Witnesses.

PER UTNE.
