TRAIN-LINE CONNECTION:

Specification of Letters Patent.

Patented Aug. 20, 1907.

To all whom it may cmwcm:

Beit known that I, FREDRXGK HAMMER, a citizen of the United States, residing at Columbus, in the county of Franklin and'State of Ohio, have invented certain new and useful Improvements in Tiain-Line Connections, of which the following is a specification.

My invention relates to train line connections and has for its object the provision of means for connecting the air or steam lines of a train between adjacent cars, in suchmanner as to accommodate the movement between the cars, but at thes'ame time dispense with the usual rubber hose ordinarily employed for this purpose;

It has been found that many serious accidents have occurred by reason of the bursting or breaking of the The air brakes now in sure maintained in the train line. If this pressure be 'suddenly and entirely released, the brakes are instantly set with such force as to slide the wheels. The disastrous effects attending upon having the brakes set in this manner, upon a train running at a high rate of speed may be readily seen. It is to provide a train line connection that will be capable of movement in either direction to accommodate the movement between the cars while the train is in motion and which may be made entirely of metal, thereby insuring long life and freedom from bursting, that the present invention is particularly designed.

In the a ompanying drawing: Figure 1 is a side elevation illustrating this improved connection arranged between the angle cocks of the air line of two opposed cars, Fig. 2 is a plan view showing the cars in dotted lines, Fig. 3 is a vertical section upon line x-x of Fig. 1, and, Fig. 4 is a detail sectional view through one of the joints of the connection.

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring to the drawing, the numerals 5 designate two opposed cars. Angle cocks 6 of the usual and well known construction, are secured to the pipes 7 which comprise a part of the train line. Threaded into each of the angle cocks at 8, is a hollow stem 9. This stem is provided with a flange 10, an angular portion 1] which is adapted to be engaged by a wrench or like tool, a beveled portion 12, and beveled packing 13, said beveled packing being adapted to engage a bevelod seat 15 of an elbow 16,'said elbow terminating in an outturned threaded flange 17. A cap 18 is threaded upon this flange and engages the beveled portion 12.

and the flange 10 to press the packing 13 firmly into engagement with the seat 15. The cap 18 has a down wardly extending lug 19 which receives a set screw 20, the inner end of said set screw binding againstthe elbow 113 to prevent the cap 18 from turning with relation to said elbow. 'Said cap and said elbow, however,

both turn with relation to the sleeve 9. Threaded into the elbows 16 are short downwardly inclined pipes 21,

said pipes extending from the angle cocks beneath the draw bars which have been illustrated in dotted lines.

in Fig. 2. The provision of these pipes 21 extending beneath the draw bars, brings the rest of the structure into longitudinal alinernent beneath the draw bars. The ends 22 of these pipes are downturned and are threaded into the angular portions 23 of hollowstems similar to the hollow stems 9,,the angular portions 23 corresponding to the angular portion 11 of the stem 9. The joints formed by these portions are indicated by the reference numerals 24, said joints being in every respect similar to the joints formed by the parts 9 to 20. Further description of these joints is therefore believed to be unnecessary. I

Threaded into couplings 25 which correspond to the coupling 16 of the previously described joint, are short preferably curved pipes 26,-the outer ends of which are connected by elbows 27 with the stems 28 of joints 29, these latterjoints being similar in all respects to the previously described joints, except that they lie in a vertical instead of a horizontal plane.

Elbows 30 of these latter joints, which correspond to the elbows 25 of the previously described joints, are connected by short preferably curved pipes 31 with the elbows 32 of joints 33, said joints 33 being similar to the joints 29. Elbows 34 connect the joints 33 with pipes 35, V Coupling members 36 adapted to engage with each other, and eonstructed like the usual couplings used to connect the air hose now in use, are provided upon the outer ends of these pipes. Those coupling members form no part of the present invention and consequently require no further description.

From the foregoing description, it will be seen that the pipe 21 is adapted to swing in a horizontal plane from the first of the joints described, together with all of the parts carried thereby, The parts carried by the joints 24 are likewise adapted to swing bodily from said joint in a horizontal plane. The joints 29 and 33 permit vertical movement of the parts, these double joints permitting considerable vertical movement without varying to any considerable extent the angle of the pipes 35 and consequently permitting the coupling members 36 to readily engage with each other. It will therefore be seen that simple and efiicient means have been herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purpose lor which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

What I claim, is:

1. in a device of the character described, the combination with a section of metallic pipe, of means for securing said pipe to a train line at one end 01 a car in such manner that said pipe is adapted to swing horizontally from said connection, said pipe extending from the-train line, beneath the draw bar, a second section of metallic pipe having air tight connection with the tirst named section and adapted to swing in a horizontal plane with relation thereto, a third section of pipe having air tight connection with the second named section and adapted to move vertically with relation thereto, and means for connecting the last named section to the coupling member of an adjacent car.

2. in a device of the character described, the combination with a section of metallic pipe, of means for securing said pipe to the train line of a car at one end thereoi in such manner that said pipe may be swung in a horizontal plane, a second section of pipe having air tight connection with the first named section and adapted to swing in a horizontal plane with relation thereto, a third section or pipe having air tight connection with the second section and adapted to move in a vertical plane with relation thereto, a fourth section of pipe having air tight connectionwith said third section and adapted to more in a ver tical plane with relation thereto, and a coupling member carried'upon said last named section which is adapted to engage with the coupling member oi an adjacent car.

3 In a device of the character described, the combination with a pair of metallic sections of pipe adapted to be secured to the angle cocks oi! a train line atthe ends'of opposed cars in such manner as to swing in a horizontal plane from said angle cocks, of a second pair oi sections oi metallic pipes having air tight connection with the first namedpair and adapted to swing in a horizontal plane with relation thereto, a third pair of metallic pipes having air tight connection with the second pair of pipes and adapted to move in a. vertical plane with relation thereto. a fourth pair oi. pipes having air tight connection with the third pair of pipes and adapted to move in a vertical plane with relation thereto, and coupling members carried by the free ends of the last named pair of pipes which are adapted to engage with each other.
