AIN STOPPfNG APPA APPLICATION F11 Fm 0 9 1 om E P A D E .To all whom; it may concern:

Be it known that I, J 01in HERBERT KING, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and Stateof Ohio, have invented certain new anduseful Improvements in Train-Stopping Apparatus, of which the following is a specification.

This invention relates to certain improvements in that class of devices which are especially designed for usefor stopping railwaytrains and by the use of which such trainsinay be automatically stopped by authorizjed persons along the-line of railway when approaching points of danger -such as broken tracks, bridges, &c., and stalled or wrecked trains' and the object of the invent1on is to provi e a device ofthis general charmen wholly avoided.

The invention consists in certain novel features of the construction, combination, and arrangement of the several parts of the im proved train-stopping device whereby certain important advant esare attained and the device is rendered simpler, cheaper, and otherwise better ada ted and more convenentgoruse, all as wil be hereinafter fully set ort The novel features of the invention will be carefully defined in the claim.

In the accompanying drawings, which serve to illustrate my invention, Figure 1 isa side elevation showin the forward truck,

pilot, and parts of the ame of a locomotiveengine, to ether with a portion of the railwaytrack an equipped with a stopping device embodying my improvements; and Fig. 2 is a front e evation of the parts seen in Fig. 1, but on a 18.1fm scale, the truck and the pilot being ornitte Fig. 3 is an enlarged partial plan view of the arts seen in F" 2. Fig. 4 is a view somew at similar to Fig. 2, but drawn to a smaller scale and showing a modified arran ement of the improved train-stopping mec am'sm;

Referring first to Figs. 1 to 3, 1 indicates a portion of the frame of an ordinary locomo- Specification of Letters Patent. Application filed April 8. 1905. Serial No. 254,473.

TRAIN-STOPPING APPARATUS.

Patented June 12, 1906.

is secured a bracket 5, having an arm 6 horizontall y extended toward and beyondone side of the engine-frame, so as to overlie the ends of the ties 4 4 where the same project outside the track-rails 3. The extremity 7 of the projecting arm 6 of bracket 5 is bent downwardly toward the ties 4, but has its lower edge sufliciently elevated to permit it to clear the rails, as is requisite in order that the engine may pass switches, sidings, and the like without breakage of the parts; 8 indicates a pipe carried upon the -engine-frame and designed to contain air under pressure, said pi e being connected with and forming part 0 the train-pipe of'the air-brake apparatus upon the engine, and in said pipe 8 is arranged an exhaust-valve 9 of any desired construction, the plug or stem ofwhich isprovided with an arm 10, havinguconnection with a spring 11', the opposite end of which is secured upon the 'engineframe 1' in such a way as to causethe-tension thereof to be ex-, erted to move the arm 10, and through it to turn the valve-plug 'into openedposition in orderto thereby exhaust the air from pipe 8 and lower'the pressure of the air in the trainpipe and brake-cylinders, so that the airrakes will be automatically set in the ordi-- nary way. At 13 is a ringor eye carried on the en ine- frame 1, and 12 represents a cord or similar easily-broken connection, one end portion whereof is passed through the ring or eye 13 and is attached to the arm 10 of the valve-stem, whilethe opposite end of said cord or fragile connection 12 is extended horizontally beneath the arm 6 of bracket 5 in a plane above the level of the rails 3 and is connected in anypreferred way, as seen at 14, with the downwardly-extended extremity 7 of said bracket-arm. 15 represents an actuating device herein shown as formed of a metal frame having at its upper part an inclined sharpened or knife edge 16 and provided with pron s or points 17 and 19 adapted to be engaged the ties 4 in such a way as to cause said frame to be su ported upon the tie with its inclined knife-e e 16 in position to engage and cut or sever the cord or fragile connection 12 when 'the engine carrying the same shall have reache a position opposite the tie whereon in the upper part of one of frame 15 is secured.' As'herein shown, the frame '1 has opposite lateral Wings or arms 18 r 18, designed to rest upon the top surface of as seen in Fig. 1, and the the tie t to steady the frame and revent the same from being tipped or topple overwhen the cord. or connection 12 strikes upon the knife-edge 16. I

As herein shown, the rearmost pron clination from the under surface of the frame 15, so that said plrong or point is adapted to be driven into e rear surface of the'tie 4,

rongs or points 19 are formed in line with the ateral' arms or proj ect'ions 18-18, two of said last-named prongs or points being near the extremities of the arms themselves; but it. will be evident that this arrangement is immaterial to my inventendants, so that incase of necessity suchemployees asmay be present at a point of danger upon the ins may quickly and conveniently set said frame or device 15 in o sition upon the tie to cut or sever the cor or .fragile connection 12 at the pilot of an approachinglen'gine, and thereby to automatic: any set t e air-brakes to stop the train before accident is possible, and in this way it will be seen that the apparatus is capable of operation in a substantially automatic and certain manner and does not depend for efficiency upon the care, attention,' or judgment of the enginemen in charge of the approaching train. It will also be apparent that the improved apparatus avoids all liability of accidents arising from inability or failure of the engineman to understand or comprehend warnings and signals, as frequently occurs in the use of other devices and particularly during fogs and storms. It will also be a parent from the above description that the improved train-stopping apparatus constructed according to my Invention is of an extremely simple and inexpensivenature and requires but little change in the brake or point 17 is set at a forward and downwar inapparatus commonly in use, being for that reason especially well adapted for employment in railway service, an it will also be obvious that, the device iscapable of some modi fioations without material departure from the principles and spirit of the invention, and for this reason I do not desire to be understood as limiting myself to the precise form and arrangement of the several parts of the device herein set forth in carryin out my in vention in practice. For examp e, in Fig. 4 I have shown a modified arrangement of the im roved apparatus wherein the exhaustval i e 9 has a laterally-directed arm 20, the free end of which is adapted forenga'gemnt with a cam projection 15, similar to the; frame or actuating device 15 above' referredj to and secured upon the tie4. The 0 p09 site end of arm 20 has a V edge 2.1, ,a apted for engagement with the'benjtfendof a,

spring22 on the engine-frame, which normally holds the valve in closed position except when the arm 20 on contact with the inclined cam-surface of the framei5? is elevated in such a way as to force the V edge of the arm-put of engagement with said spring.

22 and therebyo en theeXhaust-valve 9 of the trainpi}pe on t e locomotive.

Having t I claim, and desire to-secure by Letters Patouti is+ 1 train-stopping a I aratus comprising. a train-pipe connected viiilh the brake mechanism an having an exhaust-valve, a projectus described my invention, what I ing arm for said valve, a bracket secured to i the englne and havmg a horlzontal arm extended outwardly, the outer end of said horizontalarm being bent downwardly to' aline with said valve-arm, a fra ile connection having one end secured to sai valve-arm and the opposite end secured to "said downwardlybent' end of the horizontal arm, a: spring connected'to the-op osite end of said valve-arm and secured to t 1e engine, and an actuating device having an inclined knife-edge to enga e said fragile connection.
