HOSE-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 625,831, dated May 30, 1899. Application filed September 2d, 1898. Serial No. 691,786. (No model.)

To a/ZZ whom t may concern:

Be it kn own that I, ANDREW JACKSON GoN- LEY, a citizen of the United States, residing at Luling, in the county of Caldwell and State of Texas, have invented a new and useful Hose-Coupling, of which the following is a specification.

This invention is a new and useful pipecoupling for air-,pipes used upon railway-cars for air-brakes, the object of the invention being to provide an exceedingly cheap, simple, and efficient construction of couplingthe sections of which can be connected more easily than the couplings now in use and one in which the air-pressure will tend to bind the` sections closer together.

Another object of the invention is to provide aconstruction in which the coupling and supporting parts shall be 4so arranged and constructed that the movement of the car will not interfere with the successful operation of the coupling.

With these objects in view my invention consists in the peculiar construction of the several parts and in their novel combination and arrangement, all of which will be fully described hereinafter, and particularly pointed out in the appended claims.

In the drawings forming part of this speciicat-ion, Figure lis a View showing my invention as applied to the end of a car. Fig. 2 is avertical longitudinal section of the coupling and connecting parts. Fig. 3 is a sectional view on the line 3 3 of Fig. 2; Fig. t is a detail view of the tubular conn ecting-pin.

My invention is applicable to all kinds of cars and couplers, and consequently I have shown it applied to a freight-car equipped with an ordinary' pin-and-link coupling.

An angular bracketA is attachedto the bottom of the draw-head and car, thevertical member of said bracket depending, as shown, and havinga large circular opening A made therein, through which passes the rear end B of the body B of thecoupling, said body being supported4 by lmeans of a hinged loop (J, hinged at its upper end to the bracket A and passing beneath the body of the coupling, said body being recessed at this point in lorder to hold 5o `the same in aflxed position, a limited amount -in the opposing member.

of play being given, inasmuch as the loop C isnot quite so wide as the recess'. A supporting-block D is arranged upon the hinged loop, said block being substantiallyin the form of a ring and one portion thereof thicker than `the other, so that the body of the coupling can be adjusted up or down by simply turning the thick or thin portionof the supporting-block between the loop and the body of the coupling.'

The coupling is formed with a collar B2, and between this collar and thevertical member of the bracketAis arranged a coil-spring E, said spring being largerin diameter at the rear end than at the forward end in order to permit a slight movement of the rear end B. The bell-shaped mouthpieces F of the coupling are screwed into the body of said coupling, one of the said bell-shapedlnouthpieces serving to secure the tubular coupling-pin G within the bod y of the coupling, said pin having a collar G, against which the end of the bell iits, the short end G2 of said coupling-pin passing through a lock-nut H and also through a rubber gasket I, which is held in place upon the shoulder K of the body by means of the lock-nut I-I, and the longer arm G3 of the coupling-pin is adapted to pass througha similar gasket arranged in a similar manner in the opposing member of the coupling. In order to effect a coupling, it is only necessary to force the longer member of the coupling-pin into the opposing coupling member, and in case' the respective members should it loosely on account of wear or other causes the air-pressure would tend to bind the rnbber gasket I against the lock-nut H and by impinging upon the coupling-pin hold the separate parts in operative connection, it being of course understood that the bell-shaped mouthpieces are brought into contact` with each other, as clearlyillustrated in Fig. 2.

Whenever it is desired to change the coupling-pinfrom .one member to' another, it is only necessary to remove the bell-shaped mouthpiece, withdraw the pin, and insert it The supportingloop being hinged will permit a limited longitudinal movement of the coupling in a rearward direction; but inasmuch as said supf Letters Patent of the United States, is-

1. In a hose-pipe coupling of the kind described, the combination with the angular bracket, of the U-shaped Supporting-loop pivotally attached to said bracket, the body portion of the coupling supported by said loop and passing through the apertu red end of the bracket, the spring arranged between said bracket and body portion, and the ad-A justable supporting-block arranged between the supporting-loop and the body portion,

substantially as shown and described.

2. In a hose-pipe coupling of the kind described, the combination with the angular bracket, of the U-shaped supporting-loop pivotally attached to said bracket, the body portion of the coupling supported by said loop and passing through the apertured end of the bracket, the spring arranged between said bracket and body portion, the adjustable supporting-block arranged between the supporting-loop and the body portion, the detachable tubular coupling-pin having a shoulder, and the bell-shaped mouthpiece adapted to bear against the shoulder, substantially as shown and described.

3. In a hose-pipe coupling of the kind described, the combination with the angular bracket, of the U-shaped supporting-loop pivotally attached to said bracket, the body portion of the coupling supported by said loop and passing through the apertured end of the bracket, the spring arranged between said bracket and body portion, the adjustable supporting-block arranged between the supporting-loop and the body portion, the detachable tubular coupling-pin having a shoulder, the bell-shaped mouthpiece adapted to bear against the shoulder, and the rubber gasket and lock-nut, all arranged and adapted to operate substantially as shown and described.
