TRAIN-PIPE COUPLING.

Application filed October 29, 1915.

To all whom t may concern Be it known that I, EDWIN K. Kanus, a citizen of the United States, residing at Seitzland, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Train-Pipe Couplings, of which the following is a speciiication.

This invention relates to an improved train pipe coupling and the principal object of the invention is to provide a coupling so mounted that it may have suiiicient movement to compensate for vertical and transverse movement when the train is moving along the track and to further provide the coupler with an improved type of head mounted for universal movement so that the heads of the two couplers on connected cars will at all times be heldin tight engagement when the cars are coupled.

Another object of the invention is to provide the coupler with an improved valve mechanism so constructed that when the two cars are coupled the valves will be open and when the cars are uncoupled the valves will be closed thus making it unnecessary to manually open and close the valves of the train pipes when coupling and uncoupling the cars.

Another object of the invention is to provide a train pipe coupler which will be very simple in construction and consists of a comparatively few number of parts iirmly held in the proper position and thus providing a strong and compact structure.

This invention is illustrated in the accompanying drawings, wherein Figure 1 isA a view showing theimproved coupler inl longitudinal section, the valves vbeing open. Fig. 2 is aview showing the improved coupler partially in longitudinal section and partially in elevation with the valves closed. Fig. 3 is aaview showing the improved coupler partially in transverse section and partially in end eleva-tion. Fig. 4 is a view in elevation of the head of the coupler. Fig. 5 is a sectional View taken along the line 5 5 of Fig. l. Fig. '6 is a sectional view taken along the line 6-6 of Fig. 1.

The barrel or body` portion 10 of this coupler is provided with an enlarged inner end portion forming the chamber 11 having an inlet neck 12l and having its end closed by means of the cap 13. This cap 13 carries the eye 14 with which the suspending or Specification of Letters Patent.

seen that when in use air will pass into theV chamber 11 through the pipe 16. The outer end portion of the chamber 11 is threaded as clearly shown in Figs.' 1 and 2 so that the valve seat 18 may be screwed into place and removed when itis -necessary to grind the valve seat or clean the same.

The tubular stem or piston 19 is slidably mounted in the neck 20 of the barrel or body portion 10 and has its inner end portion threaded and screwed into the piston head 21, which piston head is positioned between the valve seat 18 and abutment ring 22. Packing 24 is provided for the piston head or collar 21 thus forming a tight joint and preventing leakage of air around the piston head. The stem 25 of valve 26 is pivotallyv connected with the piston head 21 by means of the pins 27 and brackets 2S and it will thus be seen that the valves can be brought into very tight engagement with the valve seat since it has pivotalmovement and therefore if it does not strike squarely upon the valve seat it can move to the proper position to fit tightly upon the valve seat. A spring 29 is placed between the abutment 22 and collar 30 which collar is removably mountedl upon the piston 19 and held in place by means ofset screw 31. This spring normally holds the coupler in the position shown in Fig. 2 with the valve closedr but permits the stem or piston 19 to move in# The neck 20 of this coupler is engaged by.

the yoke 32 carried by the sleeve l33, this sleeve is slidably mounted upon the cross bar 34 positioned between the supporting Vlic arms or standards 35. The standards 35 are l slidably mounted inopenings formed in the upper and lower bars 36 and 37 of the hanger 38 and springs 89 and 40 are provided to yieldably hold the standards and sleeve in the normal position. Therefore, although the neck and barrel of the coupler will normally remain in the position shown in the drawings, vertical and transverse movement will be permitted so that when turning a curve or when going over rough roads the barrel will be permitted to have suficient vertical and transverse movement to remain in the proper position.

The outer end portion of the piston 19 is flared and carries the ball al which fits into the socket 4t2 of the coupler head and engages lthe gasket 43. The cap 44 of this coupler head fits about the ball Lll and is secured to the-body portion of the coupler head 45 by means of the machine screws or other fasteners 46. The heads ofA the two couplers of adjoining cars can therefore' prevent the passage of air lfrom one couplerv to the other. ln order to provide a tight joint between the two coupler heads there has been provided a facing 4:7 of rubber which facing is secured to the body portion of the coupler head by means of the inner rings 48 and outer annulars 4:9, the rings and annulars being secured by means of the machine screws 50 and bolts 51.

I rhave thereforeprovided a train pipe coupler which is so constructed that the coupler heads mounted by means of the universal joint and the barrel is yieldably supported so that the coupler `heads of the two cars will not become disconnected when turning a curve so that vertical and transverse movement may-be permitted Vwhen going over a rough road. IV have further provided a coupler so constructed I that the valves will be opened when the cars are coupled and closed whenthe cars are disconnected, this being automatically done and therefore makes it unnecessary for the trainman to go between the cars in order to connect the air pipes and open or closel the valves.
