AUTOMATIC SAFETY-BRAKE.

Application led January 4,1915.

To all whom t may concern:

Be it known that '1, JACOB GEITUS, a subject ofthe Czar of Russia, residing at Ashley, in the county of Luzerne and State of ennsylvania, have invented a new and useful Automatic Safety-Brake, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed in connection with two railway vehicles, such as the tender of a locomotive lengine and a car, for the purpose of controlling the passage of air through the brake pipe, to the end thatwhen the engine is derailed, the brake will be set automatically o n-the train.

The invention aims to improve the construction of the slide, which, reciprocating on the car due to impact with the tender when the latter is derailed, servesto set the brake. l

Another object of theinvention is to provide novel means whereby the effective length of the slide may be adjusted.

Another object of the invention is to provide a novel operative connection' between the slide and the valve in the train pipe line.

Another object of the invention is to improve generally devices of the sort to which the present application appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination yand arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

tion to each other; Fig. 8 is an elevation of the adjusting gage.

In the drawings, the numeral 1 indicates a vehicle, such as the tender of a locomotive engine, and to the tender l is attached a bumper bracket 2.

he numeral 3 indicates a portion of a car and upon any accessible part of the car 3 are mounted annular guides 4 having at- Mounted to reciprocate in the guides el. is a slide which is a composite The slide includes a body 6 immediatelyvmounted in the guides 4 for reciprocation. Adjacent its rear end, the body portion 6 of the slide is provided with a viiange or abutment 7 which tends to limit the forward movement of the body 6, the flange or abutment 7 cooperating with the rearmost guide 4f. Adjacent its forward end, the body 6 of the slide is circumscribed by a rib 8. Surrounding the body 6 of the slide is a comone end of which abuts against the rim 8, the other end of which abuts against one of the guides 4. `In one end `of the body 6 of the slide there is a threaded aXial opening 10 into which is threaded an extension 11 constituting a part of the slide. Attached to the forward end of the extension 11 is a disk 12 and mounted upon the disk 12 is a resilient head 14- which preferably is made of rubber. T he head 14 is adapted toV cooperate with the bumper bracket 2 under circumstances which will be pointed out hereinafter. Fashioned in the extension 11v of the slide is a longitudinal slot 15. A lag screw 16 is threaded into the body 6 of the slide and enters the slot 15 for the purpose of holding the extension` 11 against rotation and thus shortening the effective length of the slide as will be understood readily when the operation of the invention is considered. The lag screw 16 may be held against displacement by` means of a lock nut 17.

In the exposed portion of the slide 11 are One of these openings 18 is adapted to receive a 4lever 19 whereby the extension 11 may be rotated when the lag screw 16 is removed. By rotating the eX- tension l1, the effective length of the slide may be adjusted and the distance between bracket 2. Thereupon,

the forward face of the head 14 and the rear face of the bumper bracket 2 may be altered. Into the other of the openings 18 is inserted one arm 21 of the gage 20, the other arm of the gage being denoted by the numeral 22. The arm 22 of the gage stands in front of the forward face of the head 14 and is adapted to contact with the bumper bracket 2, during the adjustment of the structure, the gage 2Oy being removed after a proper adjustment has been made. The intermediate portion 23 of the gage extends in a direction parallel to the extension 11 so as to position the arm 22 in advance of the head 14 for adjusting contact with the bumper. bracket 2.

Fulcrumed at 25 upon any accessible portion of the car 3 is a primary lever 24, pivoted as shown at 26 to a reduced lip 27 formed on the rear end of the body 6 of the slide. A link 28 is pivoted at 29 to the free end of the lever 24 and by means of a pivot element 30, the rear end of the link 28 is united with a secondary lever 31 fulcrumed intermediate its ends as shown at 32 upon any convenient portion of the car. A pivot element 33 unites one end of the secondary lever 31 with the forward portion 34 of a connection, the connection being a composite structure and including av part 35 which is threaded for adjustment into the part 34, relative movement between the parts 34 and 35 of the connection being prevented by means of a lock nut 36 which, being threaded onto the part 35 of the connection, coacts with the rear end of the part 34 of the connection.

The train pipe line constituting a part of the brake mechanism of the car is shown at 37. Interposed in the pipe line 37 is a casing 38 having lateral nipples 39 with which the pipe line is immediately assembled. Mounted to reciprocate in the casing 38 is a valve 40, pressed forwardly by means of a spring 41, a set screw 42 being threaded into the rear end of the casing 38 for the purpose of adjusting the spring 41 and consequently adjusting the position of the valve 40. Forward movement of the valve 40 is limited by a rib 43 in the casing 38. Threaded into one end of the casing 38 is a cup-shaped closure 44. Located within the closure 44 and connected therewith is a compression spring 45 united with an abutment 4G mounted to slide to a limited extent in the closure 44. The rear end of the part 35 of the connection passes through the closure 44 and through the abutment 46 and terminates in a head 47.

In practical operation, when the tender 1 jumps the trackor is stopped suddenly in any other manner, the car 3 moves forwardly until the head 14 strikes the bumper the slide comprising the parts 11 and 6 moves rearwardly in the guides 4, the spring 9 being compressed. Vhen the slide moves rearwardly, the levers 24 and 31, and the link 28 transmit motion to the connection 35-34 and move the head 47 rearwardly, the same striking the valve 40 and serving toforce the valve 40 backwardly, the spring 41 being compressed and the pipe line 37 being opened, whereupon the brakes will be set automatically. Should the head 47 move too far forwardly, the same will be received by the abutment 46 yieldingly supported on the spring 45.

As hereinbefore stated, the effective length of the slide may be altered by rotating, the extension 11 in the body 6, the lever 19 beingv employed in one of the openings 18 for securing a rotation of the extension 11, the

gage 2O being mounted in the` other o-f the openings 18 to regulate the distance between the head 14 and the bumper bracket 2, and the extension 11 finally being held in its adscrew 16.
