To all whom it may concern:

Be it known that 1, JOHN W. BAR-TH," a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Combination Car and Train-Pipe Couplers; and I do hereby declare the following to be a full, clear, and exact description thereof.

This invention relates to combined automatic train pipe and car couplings.

'. The object 18 to provide for the automatic coupling not only of the cars but also of the train pipes on sharp'curves. v

Automatic car couplers are nowin general use, and in recent years there has also been provided coupling heads for the air, steam and signal train pipes which are so constructed that they will automatically come 1 together and couple when the cars are pushed will not. interlock when the cars are pushed together. It has, however, been proposed to jmake the train pipe couplings laterally movable on the car body and connect the "same to the truck so that on curves the couplings will partake of the position of the truck and not of the car body. As the couplings are thereby held fairly close to the center line of the track coupling on curves is greatly facilitated.

The present invention relates to train pipe coupling heads so suspended or mounted that they can move laterally on the car body,

and being. connected to the truck so that on curves said coupling-heads move with the truck and are held fairlyclose to the'center of the track, thereby facilitating the coupling of the train pipesion curves;

The invention consists in mounting the draft mechanism so asto have free flateral movement with. reference. to the. .car body and connectin' the. amers the truck so as to be centered y the latten'and suspending bolster 3 of the truck 4;

the train, pipe coupling heads from draft mechanism so mounted.

The invention also consists in so connecting the train pipe coupling head to the pivot pln offthe car coupler as to prevent the train pipe coupling head falling onto the track in case the pivot pin should break; and also providing 'means which will indicate to the inspector that the pivot pin has broken;

.lnthe accompanying drawin s, Figure 1 is a plan view showing the ends 0 two car underframes with my invention applied there to; Fig. 2 is a vertical section taken substantially on the longitudinal center of thecars Fig. 3 is a transverse section taken immediately in front of the draw bar and supplying bracket;

Fig. 4 is a vertical sectionshowlng a portion 1 of Fig. 2 on an enlarged scale; Big. 5 'is an enlarged side view of the car coupler head and Fig. 6 is a front view of the samet The car underfr'ames are shown at 1, and

these will be provided with the usual body bolster 2 having a center late resting upon 0th the car body and truck may be of any preferred construction.

The car couplers themselves may be of any suitable automatic type, those shown at 5 being the standard Master Car Builders form, and are so well known that detailed descrip tion thereofis unnecessary. These couplers are connected to any suitable draft and buffing rigging indicated diagrammaticallyby the draw bar 6. Thelatter instead of being mounted between draft timbers, as is' generally done, is pivotally connected to the car'body so as to swing freely laterally thereof. As shown inv the. drawings the draft -mechanism is connected by a vertical pivot 7 to the body bolster of the car, but obvlously' it may 'be pivoted to any other suitable portion; of the car body. The beamsS for supportin the end of thejcar body or platform and w iich correspond to the: usual draft shown, inlor' or to allow thedraft mec ism to swing freel "The draft mechanism ,beams,-ares' read "or splayed outwardly as v 'of' thetw'o ends 0 "a car are independent of each other; In orderto hold' said draft the'truck oneurves. flhe'sp'ecific connecmechanismsu stimtially central. of thetrack 'it is connects by an suitable means to the: truck so as to parts o of the movement of r tion shown comprises a yoke 9 embracing the draft mechanism and provided with arms. which are suitably connected to any convenient portion of the truck. Preferably .these arms-will be connected to the truck by means of horizontal ivots, as shown at 11, so as to allow for re ative vertical movement between the car body and truck. Preferably movement in the between the yoke and. sides of the draft mechanism. Any lother suitable connection able form cap between the draft mechanism and the truck will answer my purpose equally as well. The train pipe couplings may also be ofany suit-- able of coupling automatically when the cars are pushed together. In the drawings I have shown-a standardif'orm' of coupling head 14, the samebeing provided with sloping faces, Wings or arms whichguide .the sections together when the cars are pushed together. hesecoupling heads have connected thereto" hose sections 15 which in turn are connected to the train pipes of the cars. As many hose sections Wlll be connected'to the heads as there are train pipes service to be coupled; In passenger practice there .Will generally'be three such pipes, one for 'the air brakes, another forthe steam, and

another for the signaling system. For freight generally only one pipe is necessary; but for as g the Goodwin dump cars, in which the dumping mechanism is operated by fluid pressure, additional pipes maybecome necessary. The trainpipes 16 preferably end just outside of the body bolster and are flexibly connected to pipe sections 17 mounted to swing with the draw bar andouter ends connected to the coupling. heads by the hose sections 15. In the drawings the pipe sections 17 are shown mounted on the bottom of the draft mechanism and connected to the train pipes 16 by flexible pipe couplers 18. This constitutes inefiect a sectional or flexible train pipe andpermits of the'use of onlyshort hose sections 15 even with a draft mechanism which swings later-'1 ally through a large are.

I The train pipe coupling heads 14 will be connected to the truck by any suitable mechi anism so as to partake of the movement of said'truoks on curves. This connection may be independent of the connection of the draft.

mechanism tothe truck. Preferably, however, and for simplicity, the train pipe cou ling members are secured to the draft mec v .amsm so as to makeunnecessary an addi- -t1onal connection to the truck. This is accomplished by securing the rear end of the train pipe coupler member to suitable hangers 20 connected to a bracket 21 on the carcoupler or drafting mechanism. The for ward end of, the train embraces the draft inechotherwisebe the case.

. that when the pin 24 breaks' the reaches the lower end of downward movement some special characters of' cars, suchhaving theirand the parts can be coupgerwill lie practically centrally of the, nomatter what the curvature of the center of thetrack and pipe coupler head is suspended by achain 22 from a hook 23 connected to the lower end of the knuckle pivot pin 24 of the car coupler 5. The hook 23 is connected to the pin 24 by means of a trans- Verse pin 25 whose ends project into or through openings 26 in the coupler head 5. As .aconse uence, even ifthe pin 5 should break, the hook 23 and train pipe coupler head cannot fall ontothe track as would Obviously, in place of this transverse pin suitable projections of other formmight be provided on the hook 23.

.In order to make detection of a broken pivot ,pin 24 easy the construction is such the pin 24 breaks itwill permit the train p'pe coupler head to drop somewhat, thus indicating to the inspector that the in is broken. This is provided for-by making the openings 26 in the form of vertical slots, as shown in Fig. 5, so that in case train pipe coupling projection or pin 25 the slots. Further of the train pipe coupling head is then arrested but the position of the head will be such as to inform .the inspector at a lance that the pivot pin is broken. At tie same time the train pipe coupler head is prevented from falling onto the track and possibly causing derailment or other'serious accident.

The combined draft gear and train pipe coupler head is of considerable weight and especially'on passenger cars where the draw bar must be very long. Said combined parts therefore offer considerable resistance head will drop until the to lateral movement. The draw bar is su ported on the horizontal bracket 27 and in order to relieve the friction of the heavy draft mechanism thereon, I provide suitable friction reducing devices, such as the rollers 28 between the bracket and the draw bar. These rollers may be su able way but preferab y are mounted beported in any suita tween the brackets .29 on the draw bar. Preferably these rollers are slightly conical,

as shown, with the small ends pointing toward the ivot 7 of the draft gear. I When t e car moves-on a curve, the truck will swivel with reference to the car body,

thus through :the connections described swinging the car cou ler and draft mechanism laterally with re erence to the car body,

Any suitable form 0 automatic car coupler and any suitable form of automatic train pipe coupling heads are adapted for my purpose, and the connections between these and the truck may also be of any suitable form, the essential being that these couplers shall move with thetruck rather than with the car body.
