TUBULAR MOUNT FOR TRAIN CONNECTERS.
Application vfiled May l'i, '1922. Serial No. 561,705.
To all whom t may concern:
Be it known that I, EDWARD A. ROBINsoN, a citizen of the United States, residing at Montreal, Granada., in the Province of Que bec, Canada, have invented a certain new and useful Tubular Mount for Train Con neoters, of which the following is a specification.
My invention relates to automatic con necters for uniting the air and steam train pipes of adjoining cars in railway trains.
The purpose of my invention is to support the head by a tubular yoke having a lateral opening for access to one of the pipe connections.
A further purpose is to provide a flexible connection from a sliding train pipe terminal locked against rotation in a connecter head, so that the flexibility of the pipe serves the saine purpose as the turning of the terminal and, preferably, to mount a disconnection fitting upon the connection.
A further purpose is to mount a tubular yoke, or support for a connecter head upon a spring connecting with the bracket.
Further purposes will appear in the specification and in the claims.
I have preferred to illustrate my invention by one general form only, selecting :1 form which has proved to be practical, eficient and inexpensive, and which at the same time well illustrates the principles of my invention.
Figure 1 is a side elevation, partly broken away, showing the preferred form of my invention.
Figure 2 is an enlarged side elevation, largely in longitudinal section, showing a portion of the structure of Figure 1.
Figure 3 is a longitudinal section, partly in side elevation showing mating heads in contact, with the gaskets joined.
Figure 4, is a section upon line 4-4 of Figure 2 upon alreduced scale.
Figure 5 is a fragmentary longitudinal section showing a flexible. train pipe connected directly to a train pipe terminal.
Figure 6 is a fragmentary section on a smaller scale in which such a flexible connection terminates in a Westinghouse coupler for connection to the corresponding coupler upon a train pipe.
In the drawings similar numerals indicate like parts.
Describing the construction shown, for purposes of illustration and not in limita tion, the head b is provided with one or more chambers c extending parallel with the track and with each other where more than one is used. These are for the terminals of train pipes. These pipes are usually one or two in number where they are used on freight cars and three in number for passenger service. They are referred to herein generally as train pipes without regard to the specific use intended. The chambers shown in Figures 2 and 3 are for a cent-ral and an end head terminal respectively.
These chambers are circular in cross section and extend through the. head from the front face to the rear, so arranged as to present a rear threaded opening b for a removable abutment upon a collar or ring d or d in the figures. In these figures the collar is screwed to lplace and the outer portion d2 is formed as a wrench hold so that it can 'be inserted or withdrawn as required.
The outwardly facing chambers, however formed, are shown as of uniform diameter, to receive bushings or sleeves here referred to generally as train pipe terminals, illustrated at g. The front end of each sleeve has a head f of a diameter to fit and slide within the chamber, while the rest of the sleeve is of reduced diameter iitting the interior of the collar d (or d), both iits being free enough to permit movement, at the same time that they are close enough to give suiiicient guidance.
An expansile helical spring e is also contained within each chamber, encircling the bushing, one end resting against a stop in the form of the collar or shoulder d or d and the other end against the head f upon the sleeve. The effect of this, if unrestrained, would be to project the slee-ve forwardly until the spring ceases to expand, giving a considerable projection of the forward end of the sleeve beyond the face of the head, but so far as heretofore described. unrestricted and lacking in control and without initial or normal compression of the spring.
In the form shown these train pipe terminals are intended to be inserted and removed from the rear of the head, by removof noimaI projection 'of each terminal through Yand"`be'yond the front Iaceo' the connecter head (directly deteriiiining the projection `as compared with lthe coupler) maybe adjusted byfa stop iz., which is most conveniently oriiied as a'nut and may to advantage comprise loch nuts `screwedupon the inner end'of the bushing. r1Ehe nut or nutsv tighten the compression spring and consequently "limit lthe forward position ci" t'lietrain'pipe terminal beyond the face of the connecter head; Iii 'addition to the stop zupon fthe'threaded sleeve, g, the trainpipe coupler 'is'scr'ew'ed upon 'the sleeve "vend and acts as a limit to outward movement'ot the lo'ck nut orlock nuts.
The outer endof each terminal-(bushing)` y is internally bored'at I and `furthergrooved at to provide Jfor insertion of a gasket "(ls, when intended torair') whichiits within the bo'refand "groove and projects at the front farenoughto provide for asuiiicient degree of 'compression of 'the 'gasket when it engages 'a Correspending gasket ont another connecter head. The gasket corresponds in its'int'erior 'diameter in each case with the iiiteriorfofthe 'bi'ishin'g g, and each. or the terminals with" the gasket because oi the bodily movement compressingthe spring constitutes what may be termed a'imo'vable gaskets-lecite.
The: head iscarried by a? bracket m which is'tiightened 'at "the upper end at nl, by a wedge n fand at its lower lend is threaded Ato receivef'afspring. The threaded member split/ato t'o'orma clamp tightened about the spring by a bolt p so' that asp-lit nut g isformed at the lower end of the bracket.
,Tlie lspring 7 at l its opposite end is threaded into a 'corresponding split nut s split-at ,aiid tightened by a nut fu. This split nut storms one end'ofa tubular supper-tw, 'which is slotted at Q02 so as to permit. insertion of the pipe tern'i'inal :in Ears` or' wings are sho'wnatb p 'I`lie bracket construction shown has vthe advantage' of preventing rotation of sleeve g, `niaii'itaining itv in position,'and 'holding 'up thepipe connecting therewith.
v In assemblage the spring and collarfare placed upon the pipe terminal followed by the nut h. The parts .are then inserted from the rear,fand'the jcollar'is secured lto ip'osi tion. The nut 7L is then tightened until the desired compression otspring c is secured. 'llie iitting is then applifedfaiid the terminal is screwed into the fitting from the front by any suitable Spanner or other wrench which may engage with the surface, with lugs g or within openings in the front face or interior oi3 the terminal,
The fitting may be finished in any suitable manner for connection of the car train pipe, and it makes no diierence whether thepart engages with" the Vwalls of the recess to prevent rotation and tojinsure the saineposition oi: the parts for repeated ments, or whether the ytrain@ei'i'iper "engages with thesewalls to 'prevent eeot'iye rotation. In either event 'tearing "of the gafslvrts by attempted turning while the cars are coupled and undesirable change of' the gasket position are avoided. j I n In Figures `5' and 6' the fittings batter# minatein nipples 'x3 and are connected by any ordinaryl clamp with :a flexible hose y. In Figure G this hose carries a couple-r .e for connection with 'the corresponding c'npler oic a train pipe.
The httings 'rc2 upon the intermediate terminals are curvedto v'give better access Eto the stop nut In Those 'upon the end'ftteiiniiials may also beurved to adiantage. The invention may be appliedt li'earlsfli'ay-A ing a single terminaldnlly, in sortie freight service, or to 'heads 'having'two or iifiorii"terel minals.
The hose jz/ allows the coupler e' lto be swung to any desired position :a'id through any desir'edcurve otinovement tor'cupliiig.
It will be obvious 'that other forms of'laterally-opei'i Aliollovv and preferably tubular supports 'may be used, connecting' with the head `by 'specifically different forms of cnstruction according to ithe whim or `need df the designer but v@mbodying allor partf my invention, and I desire to iiieludefhereiii all'such ch'ange's as "cine within th'ereasonable' spirit and scope ofmy'invfei-itioii; v
