Application filed October 19. 1905. Serial No. 283,414-

To a whom it may concern:

Be it known that we, DANIEL P. FAHRNEY,

and residents of Springfield, in the county of Greene and State of Missouri, have invented a new and Improved Hose-Coupling for Cars, of which the following is a full, clear, and exact description.

This invention relates to couplings for connecting the cars of a train, the purpose of the invention being to rovide efficient means for connecting the airose and other hose which should run throu h the train.

The object of t e invention is to produce a coupling of simple construction which will couple automaticall when the cars are brou ht to ether an which will have a -desirab e fiexi ility, ada tin the device for the passing of curves an ena ling it to accommodate itself to roughnesses in the road-bed.

The invention consists in the construction 7 and combination of parts to be more fully described hereiuafter and definitely set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical central section taken through two adjacent cars at the coupling and showing our hose-coupling ap lied t ereto.- ,Fig. v2 is a bottom plan of the arts shown in Fig. .1. Fig. 3 is a horizonta section, u' on an enlar ed scale and passing throug the principa parts of the coupling, representin the .same in the act of coming together. f ig. 4' is a side elevation of one of the parts shown in Fig. 3; but with a spring, to bejreferred to here nafter, represented as removed; and Fi 5 is a section taken substantially on the fine 5 5 of Fig. 3.

Referring morelparticularly to the parts, 1 and Zrepre'seiit t e adjacent extremities of two cars, the same be ng provided with a couplin 3 ofl an common construction. From t e underside of this cou'plin 3 we sup ort horizontally-disposed draware 4 an 5,the bodies of wliichlaire disposed lonitudinallv on the'centrafaxis "o'fthe cars and eneath the coupling 3 as will bereadily understood! These bars 4 "and 5 'are not attached to ether, butfare'simply "supported,

respective y, from the adjacent parts of the coupling 3, so that when the cars are coupled together their ends lie adjacent. To the adj acent extremities of these draw-bars 4 and 5 we attach hangers 6. As shown in Fig. 1, these han ers consist of bars bent to angular form, so t at each presents a horizontal arm 7 and a vertical arm 8. The horizontal arms 7 are attached by pivot-bolts 9 to the under sides of the draw-bars 4 and 5, as indicated. These hangers extend in opposite directions, so that the arms 8 thereof are disposed remotely from each other.

In the vertical arms 8 of the hangers open ings 10 and 11 are formed, the said openings being arranged in horizontal alinement with the corresponding openings of the opposite hanger; n the openings 10 we mount the stems 12 of our coupler l3, and the rear extremities of these stems 12 are formed with a return-bend 14, so that tails 15 are provided projecting inwardly, and these tails 15 pass through the openings 11, as shown. These openings 11 are elongated vertically, so as to form slots;- To the adjacent extremities of the stems 12 coupling- heads 16 and 17 are attached, the construction whereof is most clearly shown in Figs. 3 to 5. These heads consist ofmassive blocks. The head 16 is formed with an inclined forward face 18, so that it resents the appearance of a wedge. The orward extremity 19 is formed into a air of op ositelyrojecting horns 20, which orm a sufistantial y V-shaped recess or throat 21' therebetween, the central axis of the said throat 21 being disposed in a horizontal plane, as indicated most clearly in Fig. 4.

Near the rear face 22 of the coupling-head 16 the inclined face 18 thereof is formed with a tongue 23, the same being tapered to its forward edge 24,-so that it presents inclined faces 25. The side face 26 of this tongue constitutes a continuation of the side face of the block 16, the same being parallel to the opposite side face, as will be readily understood. To the outer face 26 we attach a s ring 26*, which projects forwardly and in tiie direction of the o posite coupling-head 17. The purpose of tliis s ring will a ear more fully hereinafter. Tiirough the tilbck or couplin -head 16 we provide orts 27, 28, and 29. ' Fhe ports 27 and 29, which are disposed adjacent to the inclined face 18, emerge upon the rear face 22 of the coupling-head, at

which point suitable nipples .30 are provided, facilitating the attachment of hose, as will be readily understood. These ports 27, 28, and

29 emerge'upon the inclined face 18, so as to form openings 31, which are in alinement vertically, as indicated in Fig. 4. At a suitable point in the under side of the block or head port 28, as indicated-most clear y in Fig. 3,

passes diagonally through the body of the lock or head and emerges at the rear face 22,

at which point it is provided with a suitable nipple 33, facilitating the attachment'of hose,

- as will be readily understood.

' for'the attachment of hose.

against, these collars we The coupling-head 17 is substantially similar to the coupling-head 16, except thatit is of opposite or complementary form. Opposite the throat 21 of the block 16 a tongue 34 is provided, which is similar in all respects to the tongue 23, already described. Opposite the tongue 23 a throat 35 is formed, which is similar to the throat 21, the same being formed between projecting horns 36, as shown most clearly in Fig. 1

formed, which emerge upon the inclined forward face 38 of the head at the point 39, and these ports are adapted to aline, respectively, at this point with the openings 31 from the ports 27, 28, and 29, referred to above. The port 37 in this case is situated to correspond with the ort 28, which is the steam-port, and is provi ed, like the port 28, with a similar dr1pvalve 40. The ports 37 emerge upon the rear face 41 of the coupling-head 17, at which point suitable nipples 42 are rovided To t e outer face 43 of the tongue 34 a spring 44 is attached, which is similar in form to the spring;

36, referred to above.

The manner in which the coupling- heads 16 and 17 come together is most clearly shown in Figs. 1 and 2. As indicated, the inclined faces 18 and 38 come together. The tongue 34 of the head 17 is received in the throat 21 of the opposite head, while the tongue 23 is received in the throat35 of the head 17. In this Wa a. very secure interlocking of the coup 'ng-heads is brought about. In order to assist in maintaining an intimate union between the two the springs 44 and 26 are provided, the same being bent inwardly toward their ends, as shown, so as to'exert a ressure upon the opposite faces of the heads or this purpose.

- Near the rear portlo'ns of the stems 12 we provide collars 46, which have substantially spherically-formed outer faces 47. Pressin rovide 'helica springs 48, which surround t e bodies ofthe stems, as indicated. The inner extremities of these springs thrust against the heads 16 Through the body ofthe coupling-head 17 ports 37 are and 17 and tend to force the same toward each other. As stated, the rear extremities of these springs 48 press against the collars 46 and normally maintain these collars in the openings 10, which openings constitute seats or sockets for the same, as will be readily understood. From this arrangement it should be understood that the shock of bringing the coupling- heads 16 and 17 together is much reduced, as the springs absorb this force. In.

this connection it should be understood that the tails 15 of the stems operate as guides in connection with the stems 12, enabling the same to move rearwardly. At the same time the tails 15 have the additional function of maintaining the heads 16 and 17in a plumb position.

As indicated in Fig. 1, the hose connections 49 for the steam, air, and gas are attached to the nipples on the rear faces of the couplingheads.

With the arrangement described evidently a very flexible connection may be made between the hose andtthe adjacent cars. By reason of the pivot-bolts 9. the hangers 6 and 7 may adapt their positions for passing curves. At the same time the springs 48 take up'any longitudinal movement of the coupling-heads in a front or rear direction. In order to normally maintain the couplingheads in a normal or mid position, We provide chains 50, which are attached to eyebolts 51, carried, preferably, at the bends 14 of the stems 12, the opposite extremities of these chains 50 being attachedto springs 52, which are carried by the draw-bars 4 and 5, as shown. From this arrangement when the hangers 6 and 7 are displacedlaterally, as in passin a curve, the springs 52 will be extende and will return the hangers and stems imilar chains 53 are arranged adjacent to the coupling-heads, which attach to the ,same, respectively, by means of cyebolts 54,

the outer extremities of these chains being attached to s rings 55, carried by the under sides of the a jacent extremities of the drawbars 4 and 5. These springs 55, of course, when extended by displacement of the coupling-heads tend to return the same to their normal mid-position. The fact that the stems 15 are carried in slots is advantageous,

inasmuch as it enables the coupling-heads to be displaced more or less in a vertlcal plane, so that they will adapt themselves to inequalities in the road-bed or to sudden changes of grade.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1.
