CONNECTER FOR TRAIN PEPES Application filed September 25, 1920, Serial No. 412,647. Renewed September 22, 1931.

My invention relates to automatic connecters for train pipes, normally forming three hose connections Jfor passenger cars and y a single hose. or two hose connection only for freight cars.

The main purpose of my invention is to position the connecter head when not in use by means which effectively ceases to function Y in use, leaving the head untrammeled by itin accommodation to the position and movement of a mating head.

A further purpose is to mount the connecter head upon a-ca'rrier, preferably in the viorm of a yoke held lat a distance behind the head'against the rear of the supporting bracket by the buffer spring and directed to its normal position in disuse by engagement with the racket.

A-further purpose is to free the head from its directional control by the bracket so that vit can swing in all directions when engagement with another head compresses the buffer spring.

A further purpose is to maintain a guiding connection between the carrier and bracket in all positions of the head so that bufferspring retraction of the carrier will seat it reliably against the stop (bracket) which positions it normally.

A further purpose is to make the buier yspring and tie rod for the connecter insertible and removable from the bracket at the 'rear ofthe bracket without change or movement of the tie rod pin. p'

A further purpose is to make the train pipe terminals themselves adjustable in their eX- ten'sioii from the head and at the same time removable through the rear of the head Jfor replacement of parts without uncoupling the train. K

Further purposes will' appear in the speciication and in the claims.

In the drawings similar numerals indicate like parts. o

Many inventors have attempted to sup Jort train pipe'connecter's so that their heads s all be in position to mate with corresponding connecter heads as the cars come together but shall be tree to move laterally with movement of the cars about curves and vertically to interfit with heads ofother connectors notwithstanding dit'ference ot heights of the connecters of cars. i

That success in this has-been but partial has been due, to various causes, among which may be `mentioned rigid limitation of the range of movement'of the head within the narrowlimits, looseness at all times in the effort to giveplay, the use of rigid guides for y the path of compression and retraction,

swinging the heads about points too close to them and using means to position the heads normally in disuse which interferes with proper flexibility in use.

I have discovered a new form of articulation for the head by which its position in disuse is determined by a'joint between the direct support for the head and the bracket by which it is connected with the car. This joint is made whenthe head is in its foremost position and is released by rearward move* ment of the head under pressure from the 'Y mating head of another car. When the joint is released, the head is free to move freely about a pivot point supported by the bracket so that ,it may lift or lower to complete the "engagement with the mating head and'may turn to either side to accommodate track Curvesfm positioning'joint, I-providea guide to maintainl effective connection between thel head and bracket and to direct the head inret-racting movement, insuring accurateseating of the parts infdnisuse.A I

I have found further that the train pipe 'terminals carrying means vfor adjustment of theirnormal` projection, may be inserted and withdrawn fromgthe rear of a head by which they are supported so that replacementsmay be made withoutuncoupling the cars and any j terminal may be adjusted in position to in- 'y crease. the .extent of projection in case of a vworn or faulty head.

Describing the construction shown by way ofillustration and not in limitation The cast or forged bracket is supported from v'anyliixedicar membensuch as coupler 16 by suitable 'bolts 17 and any play is taken` up by one or more transverse Wedges 18. The bracketris split at 19 to provide spring so that the divided parts may grip the member -1'ritil-cr'htly` and is flanged for additional strength, here along the front at 20;

or'derto give'room for the support of the head 21 at a suitabledistance in advance ofthe bracketfiind it desirableto'slope the Y bracket downwardlyV and Arearwardly to the Blockf22fllhisfblock is specially suited to afford a seat or joint. In the illustration it attendfattheback:for this Vpurpose at 23 orilen'gagenient-by.:thelflat, front face 24 ransverselyextending carrier member yokezf` The block 1yafofithe near; atfror Y near h centerlatfito permitfiaccess" oa-trans- `versely extenidin ,iishok i282 shown .as aving aforwardly projected Fhead 29.fxfTh p i 'i i best formediasfintegral @The bra etfwithY ook van rguidepins{Ixnay In connection with this releasablel extends upwardly also so that the laterally turned feet 34 and apertured at 36 will engage with the rear of the head 21in positions preferably in line respectively with the horns 37 and 38 which receive the first blow against opposing horns in case of vany lack of alignment of these heads With'the heads of other connectors. Thefeet are held to the heads by bolts 39. j

By these or similarconnections capable of performing the intended functions the head vv1s firmly supported from a carrier most conveniently made as a yoke which seats against `the rear of thebracket Vwhen invitsfo'rward position (on disuse) but which in use is forced backwardly free fromk the seat and which cooperateswith the bracketto maintain operative relations between the `carrier and bracket. Asa result of this cooperation, through the pin and side slots thecarrier is returned to its seatl against the bracket as soon as the pressure from the opposing head is reieased. 1 Y. s

The mechanism which I show for normally maintaining thecarrier Vface resiliently in contact with the back face of the bracket comprises a tie rod 40 anda buffer spring 41. The tie rod has anjeye 42 engaging the hook 28, at 4one' end and is threaded at the other end ,as at 43. The buffer spring isheld in place under compression by atie rod nut V44 carrying a flange A45V. The eye is loose enough upon the hook to permit it to be placed and removed easily and to permit movement of the rod freely in all directions.

In assemblage of these parts the eye of the tie rod is passed overthe hook, the Ybuffer spring and washer areputfin place'andrtlie tie rod nut is screwed up to givethe desired initial tension. t i j By the construction described the tie rod and buffer spring can movein any direction vertically or laterally or to anyy extent that the looseness of the hookand eye connection for lateral movement may contemplate and rearward pressure upon the head immediately releases the face 24 lof the carrier r(yoke) from its seat lagainst the'rear face of the bracket; so that the carrier (yoke) is free to swing vertically` about the pins 26 and horizontally to any extent permitted by the lost between the sides of the carrier and guiding con-tact with the pins 26 so that the i vvvill greturn the carrier reliably to its initial position ywhen pressure upon the head is' h fig movement'of the `(whatever position in ,Y esei'pinso'ceupy-f)lwillaccommodite awide ange"fofL'verticaladjustment to meet connecter yheads off'dierenjtheights on thej adjoiningoy =`c'ars-,ffithe1extent ofsiangular movement of the carrier requiredfforwany wallsof the-slots 46 maintain adjustment being well Within control of the designer through selection of the distance from'the pins 26 to the vfront face of the connecter head. j j

. Horizontal adjustment of the connecter heads to accommodate curves is also well within the controlof the designer by curving or sloping or otherwise'relieving the side faces 47 of the bracket block so as to reduce the width of the block as it extends forwardly, or by flaring of the lugs 3l, 32 and prongs 83,34 as they extend forwardly or by both of these means. I-have preferred to illustrate the tapering of the block alone, which proves suiiicientfor the purpose.

The head 2l is supported from the bracket by the carrier and held to position by the buffer mechanism, entirely independently of the position of the connecter train pipe terminal or terminals carried by the head, with the'result that any adjustment of the train pipe terminals longitudinally adjusts them with respect to the coupling or other fixed part ofthe train, makes it possible to extend the distance at which sealing contact will -take place beyond a worn or improperly placed head. This adjustment can be made while the cars are coupled. At the same time that I provide for such an adjustment I introduce the entire train pipe terminal connection within the head from the rear, so that .a faulty train pipe terminal may be withdrawn and a new gasket or a new terminal may be put in its place without breaking the coupling with the adjoining car, greatly facilitating the change and making' it' possible to make the change without shifting.

- The train pipes are shown'at 48 as three in number, the usual number for passenger cars, though my invention is suitable also for the single train pipe connection for freight cars. The pipe couplings are shown at and are threaded upon terminals 50 carrying gaskets 51. The terminals slide within cylindrical passages 52 extending through the head and are provided with rearwardly-facing shoulders at 58 to receive Athe forward thrust of expansile springs 54, whose rearward thrust is taken by collars 56. The collars present forwardly facing surfaces and are rigid with respect to the head.

If nowk the collars 56 be-integral with the head, as may be the case and'isshown in my U. S. Patent No. 1,660,766 granted Februar;7 28, 1928, the train pipe terminal can not .be removed except through the front, requiring the disconnectionA of the cars, if they be coupled,rand the moving of one of the cars. By making the collars56 removable from the rear, I canv make the entire train pipe minals removable rearwardly with them. Accordingly I form these collars 56 as rings removable rearwardly from the head and most desirably screwed in them at 57 by he wrench holds 58. The inner surfaces 59 of the rings allow the terminals to slide through them, permitting the terminals to compress the springs 54 and thus yield longitudinally under pressure of the opposing terminals.

Nut-s 60 afford adjustment for the normal compression of the springs 54 and, correspondingly, of the normal extension of the gaskets beyond the face of the head, so that the gaskets can be adjusted separately to any .desired initial projection from the head. This makes it possible to correct for distortion, wear or faulty placing of the head so as to align the gaskets in approximately the plane desired notwithstanding the resultant faulty head position. Y

The train pipe couplings 49 are threaded upon the rear of the terminals and act as lock nuts to maintain the nuts 60 in adjusted positions.

I recognize that, in view of my disclosure herein, others skilled in the art will see many ways in which the invention disclosed may be carried out, varied to avoid appearance of infringement or to suit the preference of the designer, and purpose including herein all such forms 'as come within the fair spirit and scope of my claims.
