To all whom 'it may concern:

Be it known that we,.JACo M. BUZARD, Evnnso-N P. Conn, and FRANK H. HASLAGE, citizens of the United States, residing at Pittsburgh, Coraopolis, and Pittsburgh, resl'iectively, in thel county of Allegheny, State of Pennsylvania, have invented certain new and useful Improvements in Protecting Devices for Air-Brake-Pipe Couplings, of which the following is a specification. i

Our invention consists of mechanism for protecting terminals of `air pipes of an air brake or other system of fluid circulation in car service.

Ordinarily, the air pipes of the car are provided with rigidly. mounted terminals,

' lto which are attached the hose sections having the terminal couplings, and such \ter minals are apt to bestruck by the couplers of approaching cars -in coupling, and my jured or destroyed, especially .in coupling on curvesLQr winnie the drawbars are for any reason throwirout of normal alinemen't. Iny our invention, we provide for the mounting of the end portions of the pipes -in such a i uannei' as to provide for their automatic backward. movement, utilizing flexible connections and springs so arranged as to adapt exposed portions of the line to be depressed a\nd resiliently returned, as here1nafter inoie fully described.

ln the drawings, which show two adaptations ot' the invention, Figure 1 is a plan View, showing the couplers of adjacent cars in abnormal position,.and in contact with the pipe terminals. Fig. 2 is a'view showing the construction in elevation. Fig. 3 is a similar view, illustrating a modified arrangement. F igJl is a detail view, showing a modified construction as to the mounting of the supporting spring. Figs. 5 and 6 are detail views, showing the supporting plate for the spring and its connection with the 1 e. P1lle-ierring t the construction of Figs. 1f and 2, the coupler heads 2, 2, of well-known construction, are mounted by-their drawbars in the central framework of the cars, and when coupling on curves, or when' thrown out of alineinent for any reason, are apt to strike the terminal 3, having the usual valve and stein l and to damage thesame.

ln carrying out the invention, we provide between the outer end of the rigidly mounted pipe section 5 and a longitudinally mov- `ablesection G a section of hose 7 which is connected with the pipes 5 and' 6 with a coupling terminal 8 at each end.` Between these terminals 8 and surrounding the hose section 7, is a coiled vor helical spring 9, the terminals of whichpass through lugs l() of couplings 8 and are wound vone or more times around pipes 5 and 6, providing good con- Pipes 5 and 6 are supported by nection. hangers 11, 12, respectively, pipe 6 having the longitudinally slidable bearingin hanger 12, so that when terminal 3 is struck it will slide backwardly and avoid injury. Upon release of pressure, a spring 9 will eti'ect retraction of the section 6, thrusting Ait outwardly to its normal position, the whole section straightening out, under action of the spring, as will be readilyunderstood.

In Figs. 3 to 6 inclusive,'we show a modilied arrangement in which the several parts are the same as above described, and indicated by thesaine numerals having the exponent a In place, however, of the hanger 12, the front section 6 may be supported in a depending plate 12, beyond which extends a spring 9 bearing against a collar 13. A similar collar 14 is secured around pipe 6a behind hanger 12 to positively limit the outward movement, collar 13 acting to utilize the resiliency of the spring in thrusting pipe section 6a outwardly. Hose section 7, by its resiliency, is free to buckle under the compressive action, andA to be rereeted or straightenedin the same manner as above described. The front portion of pipe 6a is f supported by a helical spring 15, preferably in coniform arrangement, having the ter- .minal loop 16 engaging pipe (3, the upper coil of the spring being supported in a plate 17, which is bolted up underneath the end sill o1c the car. with' a groove 18 around its upper face, in which lies the upper coil of spring 15, one end of which is turned downwardly through the plate, as at 19, tixedly holding it in p osition, the coil passing downwardly at an angle through a suitably formed opening 20, as clearly shown.

Said plate 17 is provided As shown in Fig. G, the lower end of the supporting spring 15a is provided with a depending stapleor loop 21 secured by U- bolts 22 to the terminal of the wire, whereby to provide an easy supporting bearing for the section 6.

When spring 15 is attached to a steel car I structure, as in Fig. fl, a separate supporting out the main functions of the invention.

The advantages of the invention will be readily understood and appreciated by all those familiar with this class of construc tion.

lt completely obviates the liability to breakage or injury; itl maintains the con pliug terminals at their normal. position without in any way preventing or allecting their operation or n'ianipulation in coupling or uncoupling, and it effects a very material saving of cost in time and preventing breakage of the parts.

The invention may be variously changed or modified by the skilled mechanic to suit the conditions of use, but all such changes i, are to be considered aswitliin the scope of the following claims.

What we claim is:

1. In a protecting device for air brake couplings, the combination with a rigid conducting pipe, of an outer coupling pipe and terminal., a support therefor permitting longitudinal movement of the couplin'g pipe, a

/f/ hose coupling device on the inner end of the coupling pipe and the outer end of the con-- spring sui-rounding the hose section and having its end portions engaging said lugs and coiled around the pipes beyond said 4coupling devices. f

ln a protecting device for air brake coulvilings, the combination with a rigid conducting pipe, ot' an outer coupling pipe and terninal adapted for longitudinal, lateral and vertical movement, a hose section connecting the rear end of the coupliiigpipe with the front end'or the conducting pipe, a coiled spring adapted to be depressed on backward movement of the coupling terminal and to expand to return said terminal to normal position, and a helical spring depending froin the car framing provided with a looped terminal loosely engaging the coupling pipe and adapted to move later ally and vertically with it and to provide for longitudinal. movement therein.

lntestimony whereof we have hereunto alixed our signatures in the presence of two witnesses. l
