RMA C. PRIEBE, a"

I citizen. of the United-States, residingfat Blue 'connection'with the drawings, is .a descriptra1ns. v,

The device is entirely automatic inits, op-

Island, .Cook county, Illinois, have invented certain'new'and useful Improvements in niitoinaticniresignal, Air-Brake, and 'Steam Couplers pof which the following, taken in tion.

The primary obj ect of my invention is the 1 production ot a combinedair signal, air

rake and steam coupler'for rallwaycars, one

of whichis carried by and operatedautomatically and simultaneously with thecar coupler in the coupling and uncoupling of aeration and is coupled and uncoupllied with theoperati n of the 'car'coupler, w

be'accomplished without l he necessity of a ch may person going between. thecars tomake the connection or disconnection.

i Withthese and other objects 1n view the present invention'consists in the combina- .tion and arrangement;ofparts, as will be .,-liereinafter moresfully described, shown in ,the;d rawings and-pointed out in the claims, it being understood thatchan'ges in form,

- the advantages of the invention.

In carrying outmy i vention A, A represent the'knuckle pins extendlng'downwardly from the car couplers A? and carrying therein the two halves or sections B, B ofmy coup- .ling device. Each of the halves or sections B, B is provided with a vertical annular opening B through-which the knuckle pins extend. This annular-opening is ofsmaller diameter mediate of the length thereof than at the ends, which allows the coupling pins to have a slight sid'ewise motion to accom "modate themselves to the movement of fthe .Specification of Letters Patent;

"Each halt of the coupler B,-B is provlded with a bifurcated projection C, C on I upon .the other "side.

Asis obvious the openings G, G, 1 may be of any size and dimensions re uired for the purpose. Y j

, h, h, h are flexible gaskets surrounding the meeting faces of the air. pipes to form an air tight'connection between the sections when the coupler is. closed. The pipe G used tor-the steam connection is extended 1n side of the coupler section as shown inFig. 6 and is provided upon the outs de thereof with the flanges 9%, g which are secured by screws or otherwise directly to the coupler section;

The operation of the device is 'as follows: 'As the cars are coupledand uncoupled in the usual way the two sections ofmy coupler'are brought together automatically andsimul taneouslyythe flexible washers forming, a

The couplers Will be -n1ade to interchange and operate the air brakes as on passengerfexpress or mail trains, but will have no openings for the steam or air signal-connections, otherwise the operation will be the same.

I claim 1. In acoupling 'device,"the combination of the two halves or sections, knuckle pins upon which each of said sections are support ed, coiled springs surroundingsaid couplin r pins above the sections and extending on side of each section to the bottom thereof, air andstea'rn passages through said coupler sections, and means for providing an air tight.

connection between the confronting faces of said sections.

I 2. In a coupling device the combination of the two halves or sections, knuckle pins extending through each of, said sections and having connectionwith the car coupler, air

and steam pa'ssagesthrough said sections,

pipes connected through said passages and extending to the air and steam pipes of the car, flexible gaskets between the confronting faces of said sections, coiled springs supported by-the aforesaid knuckle pins and adapted to hold the two sections of the coupler together, substantially as described.

3. In a coupling device,-the combination of the two halvesor sections, each section having bifurcated groovesinterlocking with corresponding projections on the other sec tion, knuckle pins upon which said sections are supported, coiled springs surrbunding saidpins and extended outside of each of said sections, coincident air and steam passages through the said sections, fiexi hie connections between the confronting faces of said sections and means "or automatically opening and closing said couplers.

4. In a coupling device, the cornoination nai J y; )2 or smaller diameteifnifi extending through said annular opening and springs for holding said sections together.

5.. In a coupling device, the combination of. two interlocking halves or sections each of which has an annular opening extending,

vertically therethrough, each section carry-i ing projections u on one side thereof and a groove or channe -on the'op osi'te side, the projections I of one section grooves of the opposite section, coincident-= steam andair passages through said sections,

pipes connectedwith said air passages and-- pipes extending approximately through the steam passages, said steam pipes having tting into the flanges abutting against the outer sides of said sections andsecured thereto, substantially as described.-

6. In an automatic coupling device of the class described, the combinationof two inv terlocking sections, each of said sections havng an annular o ening extending vertically therethrough, sa (1 opening being of larger diameter at the ends thanat' the center thereof, pins extending through saidfopen ings, coincident air and steam through said sections, fiexiblejgas ets between the confronting faces of the two secand uncoupling said sections,

7. In an automatic coupling. device, the combination of a car couler and knuckle pins extending therethroug with two interlocking sections supported by said cou lin ti'ons, andmeans for automatically coupling pins," projections extending from each 0 said assag s ing against the outside of each section, and means iorautomaticaliy opening and closing:
