Application liled November 28, 1905. Serial No. 289.398.

To all whom t may concern:

Be it known that l, WALLACE WICKHAM CARPENTER, residing at Port Jervis, in the county of Orange and State of New York, have invented certain new and useful lmprovements in Conduit-Couplers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertainsto make and use the same.

This invention relates to improvements in means for connecting conduitssuch as for fluids, gases, electric currents, and the likebut more particularly it concerns an automatic connection between the various units of a train or other vehicle of transportation.

Heretofore resort has been had to connections comprising tubular lengths of highlyelastic material, such as india-rubber or the like but in usage such expedients have occasioned much trouble and annoyance, inasmuch as they rapidly deteriorate and become unfit for service. Furthermore such tubular lengths have been provided with manuallyoperable unions, and as a result the coupling of cars is necessarily attended with delays incident to the time required in manually making such connection. Moreover, this operation is fraught with no little danger to the trainmen, and as a result accidents are not infrequent.

This invention has in view, among other objects, the provision of a means which will automatically establish a continuity of flow between the train-pipes of coupled cars by the mere act of so connecting the same.

Another obj ect of this invention is 4to eliminate rubber connectors and the like and substitute in lieu thereof a peculiar iieXible connection which will possess a great permanency in service.

Another obj ect of this invention is to provide a means for suitably positioning upon cars the aforesaid construction, whereby the abutting parts are always in a corresponding registry with those upon an adjacent car.

Other objectsand advantages of this invention will be in part obvious and in part pointed out.

With these and other ends in view this invention accordingly consists in the features of construction, combinations of parts, and arrangement of elements hereinafter disclosed in detail as one exemplification of the underlying principles involved in the invention.

. gether.

That this invention may be more fully understood and made comprehensible to others skilled in its relating arts, there is appended as a part of this specification drawings illustrating one embodiment of the same, and

while it will be apparent that the invention may readily be otherwise applied by modifications falling within the scope of the claims the herein-stated form is that which it is preferable to employ in practice and which is regarded as an improvement over such implied variations of the same as aforesaid.

Upon now making reference to such drawings through the instrumentality of suitable characters designating features thereof it will be noted that like characters denote corresponding parts throughout all of the figures, of which- Figure 1 is a bottom plan view of the invention, showing the position occupied by the parts when adjacent cars embodying the same are coupled in the usual manner. Fig. 2 is an end view, in vertical elevation, showing the staggered arrangement of the flexible connection and also' certain details of the terminal or union for the conduits. Fig. 3 is a cross-section taken on a horizontal plane intersecting along line 3 3 and looking in the direction of the arrows shown adjacent the ends of such line. Fig. 4 is a section of one form of union between the short sections of piping which may be resorted to. Fig. 5 is a section showing a slight modification over that illustrated by Fig. 4. Fig. 6 is a similar section of another form of union.

In carrying out this invention a self-registerin union for the conduits is employed. The erein-shown embodiment of this feature is set forth in Figs. 1 to 3, inclusive, and lettered A. Such union comprises two peculiarly-constructed conduit-terminals carried by respective cars. The body portion of such terminal is designated by 1 and comprises a number of projecting prongs 2 and corresponding recesses 3 for t e reception of the prongs on the companion terminal. Such body portion may also be of a V shape, as shown, in order that guiding-surfaces may be provided for assisting in preliminarily bringing the interfitting prongs and recesses to- An orifice 4 provides for the passageof fluid in the conduit, and such orifice preferably terminates in a suitably-bashed seat 5, which preferably is parallel with the end of the car in order that correspondin seats will be in normal contact and lthe fu IOO v pressuretherebetween efficiently exerted to maintain a complete closure of the oint.

The aforesaid body portion and the features thereof will insure a perfect alinement and registry with a mate g but as the union is subject to bending forces-as, for example, when the cars carrying the same are rounding a curve-it is advisable that some provision be made to maintain thenormal relation bel-A tween the united terminals of the union. To this end I provide kabutting plates 6, which llaterally extend a suicient distance to lthe sides of the terminals. It will be understood in this connection that iiexible connections are provided between the stationary conduits carried upon the cars and the union in order that the latter may have a free movement with respect to the cars, and thereby accommodate itself to the shifting of such cars while in transit.

The means whereby each terminal of the union is carried by an 'appropriate car in such a manner that a tight union will be insured between coupled cars without interfering withv the relative movement therebe- Vtween may now be considered. A rod 7 extends through a suitable beam or other car member 8 and has its -forward movement limited by means of a suitable stop, which may consist of a washer 9, held in place by a pin -or other member 10, although it will be of course understood that various known equivalents may be resorted to for the same purpose. Such rod is normally retained in a forward position with said stop in tight abutment by means of a spring 11, which is here shown as being expansile and bearing at its ends, respectively, upon the aforesaid car Imember 8 and the outer end of rod 7. A convenient arrangement is that shown in Fig. 1,

Vin which the spring Aconvolutes directly* around the rod itself and is positioned there'- by. -It will be seen that such rod 7 vmay be retreated by a pressure upon the end thereof whichcarries a terminal for the conduit, such Ymotion being elastically opposed by said spring. It may here be mentionedthat the f vnormal position of such rod is in a forward direction and slightly beyond that occupied by the same when pressed back throu h the cars. This supporting member or yielding rod is not too tightly mounted in the car member 8 to prevent the outer end of such rod from swin ing a distance corresponding to the lateral isplacement of cars While in transit g but p 'it may be stated that the extent of such play does not in practice exceed more than a few inches and is caused mainly by the shifting 'of carswithin the limits restricted by the tread of the wheels.

The terminal-supporting member 11 is also preferably hinged at a short distance to the rear of its end, as shown by 12, to provide for ya :bending of the same within Va horizontalA l'sure of the springs.

and the aforesaid union.

plane, so that the union may freely take up a median position when the cars are rounding curves. It will be clear that because of the wings 6, hereinbefore referred to, such union will not open during this movement, being maintained in a closed position by the presj In order that a suitable vertical position of the terminals may be normally preserved, a yielding member 13, which is here shown as a spring, may be provided. Such spring 13 is afIixed at its ends to the car-body and the terminal, respectively, and

while normally maintaining the latter in a r predetermined position also permits the same to have a vertical shift either up or down Within definite limits. This construction thus accommodates for any unevenness of track or slight variations in the height of the terminals on diverse cars.

It is obvious that a flexible connection must be provided between the fixed conduits which are mounted securely upon the cars This invention contemplates a means for this purpose which while allowing movement of the union in any direction affords a durable, efficient, and inexpensive substitute 'for the heretofore-employed rubber pipes. This feature of the invention broadly consists in the use of a plurality of short pipe-sections, which are pivotally oined to one another in a fluid-tight `manner, such sections being numbered 14,

15, 16, and 17, respectively. Each section is preferably in the form of a bend or elbow with the ends parallel to planes perpendicular to one another. Section 14 is thus shown pivoted at 18 in a vertical plane to the corresponding stationary conduit 19, which is stationarily mounted upon and carried by the car. Accordingly such section 14 is free to swing in a vertical plane. Section 15 is joined in a horizontal plane at 2O to section 14 and with respect to said section may freely swing in a horizontal plane and with respect to conduit 19 may swing in a vertical plane, section 14 swinging therewith in the latter case. The other end of section 15 is pivoted in a plane normal to each of the aforesaid planes at a point 21, which oins it to the companion section 16, and similarly 16 is pivoted at 22 to section 17, which at a point 23 is pivotally joined to the body portion 1 of the terminah It will thus be seen that through the instrumentality of the-se various joints and sections the terminal has a perfectly free range of movement. The sections may be, if desired, relatively positioned by means of yielding supports comprising springs, and other incidentals of this nature might be resorted to.

In order `that the joints between the various sections will be uid-tight, it is desirable to provide them With a packing means which may be adjusted from time to time to take up wear and looseness in the same. I .have

IOO

devised for this purpose an expedient which is broadly shown by Fig. 4 and in which sections, such as 15 and 16, are provided to telescope the one within the other. A channel is provided in the outer section, and within such channel is placed packing-rings 24 and 25, such packing-rings being conical in contour and overlapping one another, so that when pressed together they will be expanded in cross-section and brought to bear with any desired degree of tightness upon the telescoping portion of pipe 15. l/Vhile I have shown such telescoping portion as being a reduction of a pipe-,section 15 corresponding in external diameter to section 16, nevertheless it will be apparent that a pipe of lesser external diameter may be employed, and such pipe may without any reduction extend telescopically into section 16, if so desired. I have shown several modes of expanding the packing-rings to tighten the joint. Thus in Fig. 4 a nut 26 is screw-threaded similarly to each of the telescoping sections and serves not only to retain such sections against withdrawal, but also maybe screwed home against the packing-ring by means of a suitable spanner or other wrench. In the modification shown in Fig. 5 I have illustrated an auxiliary lock-nut 27, which may be employed to keep nut 26 from working loose. In Fig. 6 section 15 is shown provided with a shoulder 2S, which directly bears against said packingring, such shoulder being either integral with said section 15 or affixed to the same in any suitable manner. A nut 29 is screw-threaded externally to section 15 and may be turned to abut the aforesaidshoulder and press the same against the expansible packing-ring, and to securely position such nut a lock-nut 30, which may have its periphery lying flush with the exterior of the joined sections, may be introduced. It will be appreciated that any one of these joints will aii'ord a free turning yet fluid-tight connection between the sections.

From the foregoing it will be seen that this invention is one well adapted to attain the objects and ends set forth and that the-resultant structure may be applied to transportation units in divers Ways, with the result that the conduits carried by such units are automatically coupled in a fluid-tight connection by the mere act of mechanically connecting such units together for traction purposes. The necessity of resorting to manual adjustments is entirely obviated, and as the parts may all be made of metal the utmost durability in service is had as a necessary consequence. In some cases it will be found that a car embodying my invention might be required to be coupled to a car still fitted up in the old manner, and to this end and until the present system has been universally adopted it may be expedient to provide a cock 31, to which may be attached the hose or other connection heretofore employed. This matter of convenience may be dispensed with, according to circumstances. Vhile I have described the invention as applicable to a single conduit, I have shown on the drawings a plurality of such conduits in order that separate courses may be provided for air ,to operate brakes, gas for lighting purposes, and, if also wished, an additional pipe for operating the whistle usually located upon a train unit.

In carrying out this invention some parts might be employed without others, and new features thereof might be combined with elements old to the art without affecting a departure from the underlying principlesinvolved in the same, although the herein-described type is regarded as being a substantial improvement over such obvious or implied variations or rearrangements.

Since many changes, such as might appear to be widely different from this invention upon a cursory inspection, could be made in the above construction and many embodiments other than shown might be made without departing either from the spirit or the scope thereof, I propose that all matter contained in the foregoing description or illustrated in the accompanying drawings shall be interpreted merely in an illustrative and not in a limiting sense. Furthermore, I desire it to be understood that the language in the following claims is intended to cover all the generic and specific features of this invention and all statements of the scope thereof which, as a matter of language, might be said to fall therebetween. y
