UVVLUVTOR UNITED STATES PATENT OEEICE.
CHARLES E. MURDOCK, OE DETROIT, MICHIGAN, ASSIGNOR TO THE AUTO- MATIC CAR COUPLER HEATING COMPANY, OF MICHIGAN.
PIPE-COUPLING.
SPECIFICATION forming part of Letters Patent No. 416,230, dated December 3, 1889.. Application filed .Tune 24, 1889. Serial No. 315,436. (No model.)
To all whom it may concern.-
Beit known that I, CHARLES F. MURDOCK, a citizen of the United States, and a resident of Detroit, in the county of rayne and State of Michigan, have invented new and useful Improvements in Couplers; and I do declare the following` to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which `it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
This invention relates to means for coupling and uncoupling pipe or hose attached to railway-cars; and it consists in the novel construction and arrangementof devices, as hercinafter specified and claimed.
In my application iiledk February Il, 1889,
2o Serial N o. 299,387, I have illustrated and described a coupling' to Which the present invrntion is an improvement. In mysaid application No. 299,387 the uncoupling is eect-ed by means of ropes attached, respectively, to
the handles of the coupler and railway-cars.
I find by experiment that the use of ropes alone for the purpose is not entirely free from objection, because such ropes are liable to shrinkage and to stretching, so that they may 3o become either too short or too long and be partially inoperative.
In the drawing, the ligure represents my improved couplings, in which the letter I indicates a pipe or hose, and II2 an iron tube 3 5 attached rigidly to a railway-car.
The letter II represents an iron rod, to which is attached a short chain H2, which said chain is connected with a collar arranged around the pipe, as shown at a. The opposite end of 4o this chain is connected with the rod II, which said rod extends to and is connected with a pendenthanger pivoted at c on the coupling. The pivotal point of this hanger or trip is a stud or pin projecting from the side of the coupling, and in my application No. 299,387
is called a trunnion, provided with an antifriction roller. My present invention consists, in part, in forming such roller with an extended arm that passes downward and is connected with the rod II, as shown at C. arm of this trip or hanger is marked B.
It will be observed that my rods and chains are arranged in duplicate form, one on each side of the coupling proper. The same is true `of the trip C and collars II.
rlhe letters D and D represent levers extending downward from handles (marked 3 5) and clasping-t-runnions (marked a Ct) on the coupling. It will be observed that said lever D not only partially clasps the trunnion a, 6o but also at its lower end bears against the side of trip B.
In operation, when it is desired to uncouple the pipe or hose automatically, the coupling is removed from betweenV the two cars to which my device is attached, and as the forward car is moved, the hose .is gradually drawn np from its center or coupling-point, the trips B are made to release the clasp of the lever extending from the handle, and the 7o uncoupling is accomplished. It is obvious that this is performed because the rods II and their connections are less in lengt-h than the section of the hose with which they are connected.
In practice I sometimes dispense with the use of chains on the ends of the rods; but as a rule I prefer to use the chains, because they are better" for the movement of the cars.
'What I claim, and desire to secure by Let- 8o ters Patent, is-
The combination, with a pipe or hose ll and trip B, pivoted thereto, of a lever D, bearing against the t-rip, pipe I-l, secured to a carcollar c surrounding the same, and a combined rod and chain Il, secured at one end to the trip and at the other end to the collar c, as set forth.
In testimony whereof I aiiix my signature in presence of two witnesses.
CHARLES F. MURDOCK. In presence of THOMAS T. LEETE, J r., Jos. I.. IIAREINGTON.
