AUTOMATIC CONTROLLING APPLIANCE'FOR RAILWAY-TRAINS. 1

To all whom itvmay concern.

Be it known that I, EUGENE S. BIDDLE,EL citizen of the. United States of America, re sidiln at Muncy, in the county of Lycoming an Automatic Controlling Appliances for Railway-Trains, of which the following -is a specification.

This invention-relates to improvements in What may be termed automatic con-trolling appliances for railway trains. Y Theinventionhas primarily for its ,object to automatically effect the application of the air-brakes of a railway train for re,-

tarding the movement thereof at required points. or stations and to. carry out that end in a simple, ready and effective manner.

Further objects of the invention will suggest themselves 'as the nature of the invention is more: fully made known and its characteristics are later pointed out and the invention therefore consistsof certain instrumentalities and features of construction sub- 'stantially as hereinafter fully described and defined by the claims. 1 H I V j In the accompan "ng drawing jis illustrated the preferred embodiment. of my invention wherein it will be understood that various changes and modifications a'sto the detailed construction and arrangement of parts may be made without departing from the spirit or scope of the appended claims,

and which drawings:

Fig. 8 is a plan view of pawl and ratchet mechanism.

In carrying out. my inventlon I suita ly upon the outside of the right-hand rail, preferably a tubular rod-like or pipe member 1, the same being suitably and fixedly supported in any suitable way, upon the rail-ties as shown, said rod or pipe member being equipped with a plurality of tiltable projections 2 intervaled apart say twentyfive feet, there being preferably eight of these projections or stops, and projecting about five or six inches from said r0d; the length of said projections, however, may be varied as desired. The rod or pipe 1 is adaptedto be operated, together with the signal or semaphore (not shown) by means of a manually actuated lever 3, positioned within a station 1 or signaling tower (not shown). i

, A preferably star-likespoke d rotary member or wheel 4 adapted to engage the projections 2 of the reciprocal rod 1, is fixed,

to occupy a horizontal position, .to the lower are radually applied and the train-slowed An undulatory-faced member or disk 6 is adapted to serve as a safety-device to prevent the rod 5 and star wheel or member 4 turning any more than one eighth of the distance traveled at one time, said 'diskbeing secured to the undersideof the engine cab-floor, and the face of this member or disk 6 forcibly engages a resilient detent or dog 7 carried by the rod. 5 whereby the rotation of the rod 5 and star-wheels is re- The rod. 5 has appliedthereto withifi the l groove or race 9 containing a plurality of anti-frictional balls or bearings 10, providing-for reducing friction and the free turn- 10 ing movement of the rod. Overlying and resting upon the base plate S is a'keeper 11 housing the antifrictional preferaibly steel balls 10 within the groove or race9 but not interfering with the mobility thereoflthe fastening bolts 8 for securing the base plate or disk to the cab-floor serving to secure said keeper in its placef-Resting upon and preventing the upward displacement of the bearings or balls 10, and positioned intermediate thereof an'd'the keeper 11 is a ca 12 having a tubular neck-portion 13 exten ing upwardly through an opening in the keeper 11, and a short distance around and receiving the rod 5, said neck having a headed-and nut-equipped bolt 14: passing therethrough and through said rod for the retention of said cap in place upon the latter.

A ratchet 15 is suitably applled to the rod or shaft 5, within theengine-cab B and has engaged therewith a resiliently controlled pawl 16 for returning the handle of the engineers'lever to oil' position.

Applied'or fixed to the upper end of the rod or shaft 5 is a cog wheel or ponion 17 supported in a bracket 18,'secured to the engine boiler, said pinion or cog being interg eared with a link or rack-bar 19 connected to a "lever 20'of'the air-b'rake-valve 40; As shown in Fig. 4L, the stem ZI'eX-tends up throughpthe automatic brake-valve and receives thereon the engineers lever B. The lever 20 is adapted tofit upon an upward extension 23 onthe engineers lever 3 and is formed withfa lug or extension 22iwhich engages or contact with 's'aid engineers' lever 3, whereby movement ofthe lever 20 is communicated to the engineers lever. It will thus be seen that the air brake valve will be actuated .through this arrangement duringthe movement of the engine or train and the engineers lever be accordingly operated or thrown by the lug 22 and the air-brakes be simultaneously applied, bringing the englne or train to a stop.

' As 'pre'viou'sly stated, it will be appreciated that numerous changes may be resorted to i'fi'the various details as relates to improvising and'substituting parts so long as these fall-within the breadth of my invention as covered by the claims appended hereto. "I'el aiin: H p
