To aZZ wiwm it may concern."

Be it known that we, ADAM Emma and Joint S. T121132, citizens of the United States,

residing at Oklahoma, in the county of Uklahoma and State of Oklahoma, have invented new and useful Improvements in Train-Hose Couplings, of which the following is a specification.

T his invention comprehends the provision an automatic coupling for train hose, embodying a pair of mating sections-with which the adjacent ends of the hose sections are associated to be coupled simultaneously with the coupling of the cars, and released upon separation of thellatter.

One of the chief characteristics of the invention resides in designing the mating sections of the coupler for cooperation when coupled to exert a maximum degree of pressure toward each other at the joining point of the hose sections, with a view of providing a fluid-tight connection.

In carrying out the invention we aim to provide a construction wherein the coupling sections can be easily and positively coupled, a yieldable means being. employed to absorb the shock incident to the coupling of the sections, and further adapted to effectively hold the parts associated.

Another important object of the invention resides in the provision of a coupler the above mentioned character, wherein the hose sections can be quickly separated from their respective coupling sections, and

' oined together in the ordinary Well known mannershould for any reason the coupling bccome'impaired, thus providing the train with the necessary hose line until a terminal is reached to make the necessary repairs to the coupling. 4

The nature and advantages of the invention will be better understood when the following description is read in connection with the accompanying drawing, the invention residing in the construction, combination of elements, and arrangement ofnparts as defined in the claim. 7

In the drawing forming part of this dicate similar parts in the several views and wherein Figure 1 is a side elevation partly in section showing the coupling sections associated.

Fig. 2 is a top plan view.

' pended from draw oar Fig. 3 is a detail view of one of the coupling sections.

The coupling mechanism forming the subject matter of this invention consists of identically constructed mating sections A and B respectively, the section A. being sus- C of one car, white the section is suspended from the adjacent draw bar the next car of the section preferably consists of an eiongated body 10 having longitudinally dis posed slot ll adjacent one end for the reception of a bracket arm 12 which latter is secured to the draw bar C depending therefrom, any suitable means such as a cotter pin or the like indicated at 13 being employed and passed through the bracket arm 12 beneath a washer 18' to hold the parts operatively associated. The sections are disposed horizontally and formed with a shoulder 14 at an appropriate point in their length, a coiled spring 15 encircling each section and having one end bearing against the bracket arm 12 and its opposite end against the shoulder 14:, thereby yieldably supporting the section which is capable of sliding movement, and normally held projected beyond one end of the drawbar C.

Each section is provided with an angular shaped end portion 16 preferably of semiconical formation, while projecting laterally from the body portion 10 is a correspondingly formed member 1'? defining a pocket for the reception of the angular end portion 16 of the other section, when the respective sections A and B are coupled in the manner illustrated, Obviously the angular end portion 16, and pocket 17 of the respective sections are reversely disposed, or in other words project from opposite sides of the body portion 10 of the sections. The forw'ard ends of the sections are supported by means of a flexible element 18 such as a chain or the like. Each section is provided with a transverse bore 19 opening at both sides thereof, while countersunk within said bore is a gasket 20 which projects slightly above the meeting faces of the respective sections. Fitted within said bore and having a portion projecting therefrom is a pipe- 21 having a coupling member 22 secured thereon for association with the usual coupling collar or sleeve 23 on the ends of the hose sections 24, whereby the hose secduring which operation the spring 15 permits the sections to yield sufliciently to absorb the shock or jar incident to the coupling of the sections. The springs subsequently expand to forcibly move the respective sections A and B of the coupling toward-each other and hold the same effectively associbrought into registry, thereby establishing ated in operative position. In this position the bores 19 of the .respective sections are communication between the adjacent ends of the hose sections 24:- The angular end portions of the respective sections have inclined surfaces 25 which co-act with their mating section to'exert a maximum degree of pressure upon the meeting faces of the respective sections along the line of communicatlon between'the hose sections, whereby the gaskets 20 of the respective sections are effectively held in contacting engagement, and thereby provide a fluid-tight joint. Should for any reason the coupling become impaired, the terminals of the hose sections 24 can be readily detached from their respective pipes 19, and coupled together in the usual Well known manner, thus providing the train with the required hose line, until a terminal is reached at which time the necessary repairs can be made to .the coupling. It is of course to be understood that the coupling collar 23 while shown conventional in form, is intended to be constructed in accordance with any old and well known form of coupling, to permit the collars of the respective hose sections 24 to be coupled by hand as above stated. The construction and arrange-' ment of parts also permits the sections A and B to be automatically uncoupled simulta neously with the uncoupling and separation of the cars. It is of course to be understood that any number of hose sections can be associated with each of the coupling sections,

which only necessitates the broadening of While it is believed that from the foregoe ing description the nature and advantages of the invention will be readily apparent, we

desire to have it understood that the same is merely illustrative of the preferred embodiment of the invention, and that such changes in the construction and arrangement of parts maybe resorted to when desired as fall within the scope of what is claimed.

What is claimed is A train hose coupling comprising in combination, a bracket depending from the draw bar at the adjacent end of each of two cars, a pair of mating sections, each having a slot through which a bracket is passed, means for securing each section operatively associated with its. bracket, each section being formed with a shoulder at a point in its length, a spring encircling each section and interposed between said shoulder and bracket whereby said section is yieldably supported, each section having a substantially conical-shaped extremity, and. a semiconical-shaped pocket located at a point rearwardly of said extremity, said conical-shaped extremity of each section being adapted to be fitted within the pockets of the respective sections when the draw bars are coupled, each of said sections having a transverse bore with which one end of its hose section communicates, said bores registering when the sections are coupled, a gasket countersunk in each bore, andv one side of each of the conical-shaped extremities of the respective sections being tapered to have a wedge action against the adjacent surface of the opposite mating section to exert a maximum pressure against the meeting faces thereof in axial alinement with the bores to provide a fluid-tight joint between the sections.

In testimony whereof we affix our signatures.
