TRAIN-PIPE COUPLING.

Application led Tune 29, 1918.

To all whom t may concern:

Be it known that I, Jol-IN B. GriiNiN, a citizen of the United States, residing at St. Albans, in the Sta-te of Vermont, have invented certain new' and useful Improvements in Train-Pipe Couplings; and l do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

The present invention relates to automatic couplings for connecting the adgacent ends of the pipe lines for air and steam on railway cars. t

An object of the present invention is to provide connections for such couplers whereby when the cars pass Varound curves or should the coupling members be slightly displaced an absolutely tight joint will at all times be maintained.

Viith the above and other objects in view which will hereinafter appear as the description continues, the invention consists of the novel features of construction, conibination and formation of parts as will be hereinafter more fully described and particularly pointed out in the appended claims.

ln the accompanying drawings has been shown a simple and preferred forni of the invention, it being, however, understood that no limitation is necessarily made to the'pre oise structural details herein exhibited, but the right is hereby reserved to any changes, alterations or modifications to which recourse may be had that come within the scope of the claims without departing from the spirit ofthe invention or sacrificing the efficiency of the same.

In the accompanying drawings:

Figure 1 is a side elevation of the coupling device as applied;

Fig. 2 is a plan view of the couplers taken substantially on the line 2-2 of Fig. 1;

Fig. 8 is a vertical section through one of the couplers; and,

Fig. 4 is a horizontal detail section through one of the couplers and its connection to the air pipe.

Referring now more particularly to the accompanying drawings wherein like and corresponding parts are designated by simi Specification of Letters Patent.

Serial No. 24 672.

lar reference characters throughout the several Views.

The numeral 1 indicates ordinary railroad cars having` the draw-bars 2 applied thereto for connecting the cars together. Connected to each of the draw-bars 2 by means of the J-bolts 3 is a bracket 4 comprising a depending spring plate. Carried by each of these plates 4 is a 'bearing 5 and extending through and pivotally coi'inected to each of these bearings is a bar 6. One end of this bar 6 is connected by means of the equalizing springs 7 to the portions of the brackets l which are connected to the couplers 2', and encircling each of thesebars 6 is a shock absorbing spring S. Connected to the outer or free ends of each of these bars 6 is a block or structure 9 (usually a. casing) having formed in its front face a series of recesses 10, each of which terminate in a perforation 11 and forni a shoulder 12 between the recess and the perforation as better illustrated in Fig. 5 and there being one recess and perforation for each line of coupling. Formed with the opposite sides of the castings 9 are the wings 13 which act as guiding and engaging devices so as to bring the couplings together or allow the couplings to have sufficient play to compensate for any qualities and curvatures of the track over which the car travels.

For the usual rubber hose l employ flexible metal hose one of which indicated by the numeral 14E being for air brakes, one indicated by the numeral 15 being for the signal and one `indicated by the numeral 16 being for the heating` pipes and carries steam. Connected to each of these pipes 14 15 and 16 isa short pipe 17 and this short pipe en tends through the perforations 11- formed within the couplingheads and terminate in enlarged heads or pistons 18 which are slidably mounted within the recesses 11. These piston heads 18 are provided with internally threaded recesses 19 which communicate with the pipes 17 and seated within each of these recesses is an externally threaded ring 20 carrying a spider 21. The

inner faces of these rings 20 are formed with a concavely rounded seat and adapted to rest within this seat is one end of a sleeve which end is rounded so as toflt within Patented Jan. e, i920.

this concave seat, and said sleeve and ring forming` practically a universal joint of limited range. This sleeve 22 is provided with a spider 23 and extending through the spiders 23 and 21 is a valve stein 24:. This valve stem carries a: valve 25 which is adapted to `move within the recesses 19, the opposite end of the valve stem is provided with a head 2G and arranged between this head 26 and the spider 23 is a coil spring 27 which normally holds the valve 25 closed. Seated within the castings 9 andl encircling the pipe 17 are suitable couplings 28 so as to prevent leakage and permit this pipe 17 to move longitudinally. Each pipe 17 carries a flange 29 and arranged between the flange 29 and the couplings 28 is a coil spring 30 which normally exerts a pressure upon the pipe 17 for retaining the pistons 18 within the recesses 10.` Communicating with each of the recesses 1() is a pipe 31 and this pipe is connected to a flexible hose or piping 32 which piping ,32 is connected to the air pipe 14, so as to supply air to the various recesses 10 and force the pistons 18 outwardly so that they will assume the positionas better shown in Fig. 5 of the drawings, but their outward movement is limited by means of the coil springs 30;

From the foregoing it is obvious that as the two coupling heads are brought together the wings or guiding members 13 will direct the couplings to their proper positions and any shocks exerted upon the couplings when coming together will be taken up by means of the springs 8. After the couplings have been connected together and when any forces are exerted upon the couplings so as to cause them to move in a vertical direction, the connection between the rods (Sand the couplings 5 will permit such a movement, but these movements will be limited by means of the equalizing springs 7. The air from the pipe 111 at all times exerts a pressure upon each of the pistons 18, thereby forcing the same outwardly and when two couplings come together the sleeve 22 of the adjacent couplings will contact, and by having a continual pressure upon these sleeves they will at all times maintain an absolutely tight connection irrespective of` any movements they are compelled to undergo when the car is traveling over rough roads or curvatures of the track. When the sleeves 22 come together the adjacent ends 26 of the valve stems will contact, thereby forcing the valves 25 inwardly where they will open the connections so that the fluids may readily pass therethrough and establish a communication between the pipes of the adjacent cars. However, when .their .closed positions, thereby cutting oii' the supply of air or steam and preventing leakage. The outer faces of each of the castings 9 are provided with the bumpers 33 and the steam pipe 16 may be provided with the suitable condensation valves 34.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:
