AUTOHATIG AIR-COUPLING.

Specification of Letters ratent.

Application tiled October 7, 1910. Serial No. 585,827.

Be it known that I, Pn'rnn HALEY, a citizen of the United States, residing at Wells ton, in the county of Jackson and State of Ohio, have invented new and useful Im- 'provements in Automatic Air-Couplers, of which the following is a specification.

The invention relates to an improved train pipe coupling and is particularly directed to a construction whereby. the train pipe may be automatically connected and disconnected as the cars are coupled and uncoupled, whereby the time required and danger incident to the usual hand coupling is obviated. One of the objects of the resent invention'is the provision .of a con ing head connected to and movable with t 1e car coupling ,head, whereby as the latter yields iinder the pressure contact in the coupling operation, a simultaneous and similar movement will ipe coupling head.

A further object of t e invention is the connection of the train pipe coupling head to permit its yielding under pressure from the opposing coupling head independentl ead, and the connection wit such independently movable part of means whereby, under such independent movement, the cooperating sections of the respective coupling heads are interlocked to ,provide an uninterru ted air-tight communication between sai coupling heads for the passage of the fluid in the train pipe.

The invention in its preferred etails of construction will be described in the following specification, reference being bad particularly to the accompanying drawings, in which Figure 1 is a view in elevation illustratin' the application of the improved couead to the car coupler head and to the car frame. Fig. 2 is an enlarged plan of the improved train ipe coupling head. Fig. 3 is a lan of the ower section of the improved coupling head, the operative parts of the head being shown housed therein and Fig. 9 is a perspective view of the locking plunger.

length in the ordinary well-known manner and at each end of this car 11 between the adjacent longitudinal beams or bolsters 12 thereof is the ordinary J anney type coupler 13 for the joinin or coupling of adjacent cars in the usual way.

Connected with the draw bar of each c0uler 13 is a train or other pipe coupling lead comprising a casing or shell including upper and

lower sections

14 and 15, respectively, detachably connected by means of side plates 16, the casing or shell being mounted for ti ping and longitudinal movement indepen ent of the coupler 13 in a supporting frame comprising spaced transversely disposed cross ridge pieces or bars 17 and '18, the ends thereof being suitably secured to trunnion bearings, each having a substantially circular-shaped rim 19, with centrally arranged spaced cross webs 20 providing inner and outer side and upper and lower guide slots 21 and22, -respectively, the inner and outer side slots 21 being uniform throughout their length, and the upper and lower guide slots 22 being forwardly tapered or substantially wedgesha ed.

Siiitably secured medially of the shell or casing, at opposite sides thereof, are blocks 23, the same being mounted in counter seats 24 in the lower section 15 of said shell or casing, and are provided with outwardly extending trunnions 25, the same being formed. with cross branch lugs or trunnions 26, which enga e in the wedge-shaped upper and lower ots 22 inthe bearings of the suporting; frame, and the trunnions'25 engage in t the casingor shell of the coupling head may tilt or move longitudinally and laterally with respect to the car and independently of the coupling 13 thereon when the coupling heads of the adjacent cars have been connected together.

Integral with the upper cross brid e piece 17 centrally thereof, is one end of a racket e inner and outer slots 21, whereby or arm 27, the latter being connected or formed integral with the draw bar of the coupling 13 and the end of the arm or bracket 27 connected with the bridge piece. 5" 17 is provided with a head 28, the latter being slidably mounted in guide ways or grooves 29 formed at the inner edges of spaced parallel guide cleats 30, the same be ing suitably secured to the bolsters 12 of the --car 11, the arm or bracket being adapted to connect the supporting frame andthe draw bar of the coupler 13 together, so that on movement of the coupler 13, simultaneous movement will be imparted to the support- 15 ing frame for the pipe coupling head.

The lower section 15 of the shell or casing .is provided interiorly with

independent compartments

31, 32 and 33, the same being divided or separated from each other by 2 means of vertical partitions 34, and the 'upper section 14 of said casing or shell is likewise provided with

compartments

31, 32 and 33..adapted to register with the compartments in the lower section 15, respectively, when the sections of the coupling head, have been joined or connected together. In the outer end of the shell or casing of the couplinghead is formed an out-- wardly tapering nozzle 34 protruding beyond the outer end of the said shell or casing, and an inwardly tapering socket 35 arranged in horizontal alinement with the said nozzle and in juxtaposition with respect thereto, the nozzle 34 being provided with a 3 5 central bore 36 opening through oppositeends thereof, and in which is inserted the outer end of a tube or pipe section 37, the latter being passed through the compartment 31in the sections of the shell or casing and has its inner end connected with one branch 38 of a union coupling 39, the latter being suitably connected with one end of a flexible pipe section 40 connected with the train or other :pipe 10. This union coupling 39 has its other branch 38 connected with the upper end of a further pipe section 41 arranged within the compartment 33 of the upper and lower section of the shell or casing, the outer end of this pipe 41 being in communication with the socket 35 which latter is formed in casing.

Arranged within the registeringcompartnients 32 of the

sections

14 and 15 of the casing is a plunger rod 44, the same being formed at one end with an abutment block 45, with which contacts one end of a coiled expansion spring 46 surrounding the said plunger rod 44 and having its opposite end bearing against alining cross webs 47 of the

sections

14 and 15 of the casing or shell. The opposite end of the plunger rod 44 is formed with a forked striker head 48, the

spaced parallel forked arms 49 "of which being disposed in guide recesses 50 formed in the upper and

lower sections

14 and 15 of the casing or shell at opposite sides of the

parts

42 and 43 of the split block containing the socket 35 and are adapted to move in the path of pivoted locking dogs 51 disposed in adjacent coupling head in the socket 35 when adjacent cars are being connected together.

At diametrically opposite points of the nozzle 34' near the outer end thereof are provided notches or recesses 53 in which engage the locking dogs 51 when the nozzle 34 of an adjacent couplinghead is. insertedin the socket 35 of the other coupling head duringthe coupling of adjacent cars.

, Formed on the plunger rod 44 is a squared enlargement 54, the latter being provided with a suitable elongated opening 55 through which is passed a vertical pin 56, the ends of which engage in suitable sockets formed in the inner face of the cross bridge pieces or

bars

16 and 17 of the supporting frame, so that when adjacent coupling heads for j oining the train or other pipe 10 are brought together in the coupling operation, each head will be moved inwardly longitudinally .from'the end of. the car 11, thus causing the contraction of the expansion spring 46, as the pin 56 will maintain the plunger rod 44 passive during the movement of the shell or casing, thereby bringing the fork arms 49 into engagement with the locking dogs 50 forcing the same into the notches 53 of the nozzle 34 of an adjacent coupling head on the insertion of the said nozzle 34 in the socket 35 in the other coupling head, thereby connecting the coupling heads of adjacent cars simultaneously with the coupling of the draw bars of the couplers 13 of the said cars.

At the inner end of the socket 35 in the split .block and held in suitable recesses formed in the separable parts 42' and 43 is a resilient gasket 57, with which contacts the outer end of the nozzle 34, thereby forming a fiuid tight union between the split block and thesaid nozzle of adjacent cou pling heads during the coupling operation.

The upper and

lower sections

14 and 15 of the shell or casing are provided with elongated slots 58 to allow play of the pin 56 on the vertical tilting of the shell or casing, when the coupling heads of adjacent cars are being connected or during the travel of a train over a rough bed. v

When the coupling heads. of adjacent cars have been connected together, it is of course understood that the springs 46 are maintained under tension so that when it is desired to. uncouple the said cou ling heads of the train or other pipe 10, immediately upon detachment of the draw bars of the in the notches 53 in the nozzles 34, thus per .mitting the same to disengage from the recesses 35 and on the disengagement of the nozzles 34' from the recesses 35 in the coupling heads, the outward'movement of the said shells or casings is limited by the lugs 26 being wed ed in the smaller ends of the wedge-shape slots 22 of the supporting frames for the said coupling heads.

When the coupling heads have been joined or connected in the foregoing manner, the train or other pipes 10 of adjacent cars Wlll have communication with each other, and on-the disconnecting of the coupling heads, the train or other pipes 10 of said adjacent cars will communicate directly with the atmosphere in the ordinary well-known manner forthe a plication of the brakes.

"From the oregoing, it is thought that the construction and operation of the invention will be readily understood without requiring a more extended explanation.
