' TRAIN-PIPE conrLmG.

To all whom-it may concern! Be it known that I,- ERYE L; AnAMs,- a

citizenof the, United" States, residing at 'Middleton, in the county-of Canyon, State :of Idaho, have invent'edcertain, new and usefulv Improvements in Train-Pipe Oou-, plingsf and Ido hereby declare the following to be a} full, clear, and exact'description of the invention, such as" will enable-others I skilled in the art to which it appertains to make. and use the same.

Thisinvention relates to couplers of; the kind designed to connect sections of car sup-i ported pressure. pipe,

One obj ect of the invention is to simplify the construction of devices of'this character.

.Another object of the invention is to pro- Vida. a. novel means whereby such devices be-caused they are. inexact al-inement, or.not.

Athird object of the invention isto proto engage no matter whether vide anovel form of out off valve for a device of this character when the same is not engaged with another section;

the invention-consistsingeneral of atrain supported pipe coupling of improved charactor in combinationwith a novel means for actuating avallv'e held in said coupler.

andspecifically set vJkgrtli in the claims."

This coupling memberisfl-provided with a bore 21 of uniform diameter thronghg-g out its length and by-meansof;thisconstruw tion the walls of the coupling, member adj acent the face 19 are much thicker mania;- coupling member adjacent the pipe 17' 'Attached to the eye;1,6 is oneaendjof a spiral-q compression spring 22 which; surrounds the cylindrical portion of. the member 13555111 r projecting from the co'uplingfniember. c Q Upon the face of the member 1 8 -is-.an ,5 elastic washer 9A providedgwith; a plurality;

of countersunk openings-25wherein areheldj 24' firmly to the face -l9 fwhile atthezsame time, the, screw heads" being below. the 163.1%...

do not interfere with ,i-the yielding ofth-is j washer nnder working conditions. It will be noted-that the face 19 isr at right angles- 1.90 to the axis of the, member,-l8. so ,thaf WhE II two of these members come together th Mouiited beneath provided with a longit'udinal t-slot- 285 A 29 is indicated a butterflyvalve the stems rof p which project laterally through; the; sides of;

the member: 18 and which jar-e .g-squared at.

. their free ends as indicatedIatBO. Mounted:

on each of these squared-Tendsis arocke armwloo 31', the-free ends of this rockiar'mzbeing in spaced relation as canclearly-. bexseen iin; Fig. These rock arms,. lie2one omeach side of the bracket 27 and a--' bo1 -t .32: passes through openings 33 in the rock arms and through the slot 28.

In the operation of this device when two cars are brought together the washer 24 of one car will strike the washer 2a of the other car and this will cause each of the members 18 to be forced backward until the cars are coupled when they will be maintained in this position so long as the cars remain together. When in the forward position the valve 29 lies across the bore 21 but as the member 18 is pushed backward the ends ofthe rock arms 31 will be prevented from moving backward therewith and this will cause the valve 29 to rotate through a quarter of a circle and open communication between the portions of the member 18 lying on each side thereof. This backward motion is permitted by the yielding of the spring and the swinging of the triangular supporting plate 12. As soon, however, as thecars are separated the spring 22 will again force the member 18 away from the center of the car and this will close the valve by the arm 31 moving through a quarter of a circle in the reverse direction to that just described.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

Having thus described the invention, what is claimed as new, is

1. In a device of the kind described, a coupling member provided with a fiat e11- gaging face at right angles to the axis of the member, and means to yieldably support said member for longitudinal movement beneath a. car, said means comprising a hanger swung from the bottom of a car and pivoted to said coupling member, a coil spring surrounding said member and havin g an upturned rear end provided with an eye adapted for attachment to a car, and a collar on said member resting againstthe forward end of the spring.
