HOSE-COUPLING.
SPECIFICATION forming part of Letters Patent No. 427,305, dated May 6, 1890.
Application filed September 14, 1889. Serial No. 323,954- (No model.)
Be it known that I, CONRAD ECKHARD, of
, Friend, in the county of Saline and State of Nebraska, have invented a new and Improved Hose-Coupling, of which the following is a full, clear, and exact description.
My invention is an improvement in automatic steam or other. hose-couplings for railway-cars.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a plan View of the improvement as coupled. Fig. 2 is a sectional plan view of the same. Fig. 3 is a plan view of theimprovement uncoupled and with parts in section, and Fig. t is a side elevation of one of the draw-heads.
The improved hose-coupling A is provided with the two draw-heads B and B, alike in construction, and each mounted yieldingly on the under side of the car directly under or at one side of the ordinary car-coupling. Each of the draw-heads B is provided with a projection O, fitting into a corresponding recess D in the other drawhead. The outside of each projection O is connected with the end of the hose E, which latter leads into a passage F, formed transversely in the projection C. In this passage is held a valve G, arranged vertically and provided on its outer end with an arm G, extending-inward and onto the projection of the other draw-head when the two draw-heads are coupled. The movement of the arm G in one direction is limited by a stop H, and the outer end of each arm is adapted to pass over an L-shaped spring I,
.secured on the opposite offsetO. The downwardly-bent end of the spring I is adapted to pass into an aperture formed in the top of the offset 0, so that when the two draw-heads B and B are coupled, as shown in Fig. 1, the outer end of the arm G rests against the downwardly-bent end of the spring I, so as to prevent the arms G from moving until considerable force is applied, when the drawheads are uncoupled.
The valve G is provided with a diametrical opening G adapted to connect the passage F with or disconnect it from the pipe J, held to slide in an opening on the inside of the offset 0. On the inner end of the pipe J is H formed a-flan 'e J on which resses one end of a coil-spring K, resting with one end on a plate L, secured to the inside of the offset 0.
The exterior of the pipe J is preferably .cov-
ered with rubber or other suitable substance, so as to form an air-tight joint when the two opposite pipes J register with each other, as shown in Fig. 2. The valve G is also provided with a reduced part G adapted to rest against the inner end of the pipe J when the two draw-heads are uncoupled. In this position (shown in Fig. 3) the pipe J is flush at its outside with the inside of the offset 0; but when the valve G is turned, as hereinafter more fully described, the round part of the valve comes in contact with the inner end of the pipe J and moves the latter outward in tight contact with the opposite pipe J.
The operation is as follows: When the two cars are uncoupled, the arms G of the valve G stand in the position shown in Fig. 3, and the opening G of the said valve is disconnected from the passage-way F and the pipe J. WVhen the two cars come together to couple, the draw-heads B and B pass with their offsets 0 in the opposite recesses D, as is plainly shown in Fig. 1. When the two draw-heads B and B move toward each other, the arms G of the two valves G travel with their outer ends over the corresponding springs I and compress the same until they have passed the downwardly-bent ends of the said springs, at which point said springs again assume their former position. The arms G of the two valves G now come in contact with each other and are moved until they stand transversely between the stop-pins H and the ends of the springs I, as is plainly shown in Fig. 1. The movement of the arms G turns the valves G, so that their openings G connect the corresponding passage-way F with the corresponding pipe J. At the same time the valves G move the'pipes J outward, so that the outer ends of the said pipes abut against each other and form a tight joint. The hose E on the two couplings are now in communication with each other and air can pass from one pipe to the other. When the cars are uncoupled, the
sumed such an inclined position that the said springs can pass. (See Fig. 3.) The turning of the arms to their former position causes the valves G to disconnect their openings G from the pipes J and the passage-ways F. Air cannot now escape from the hose E. Thus it will be seen that the hose-coupling is very simple and durable in construction and automatically couples the ends of the hose when the two draw-heads come together.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a draw-head provided with a passage and a tube sliding in said passage, of a rotary cam-like tube operating valve in'said passage at the inner end of the tube and provided with an operatingarm, substantially as set forth.
2. The combination, with two draw-heads:
adapted to overlapand provided with transverse passages registering with each other when said draw-heads overlap, of valves in said passages, and provided with laterally-extending.antomatically-operated arms to proj ect over the meeting edges of the draw-heads, substantially as set forth.
3. In a hose-coupling, the combination,with drawheads having a passage for connection with a hose, as specified, and a rotary valve arranged" in said passages, of rigid arms applied to the draw-heads exteriorly and attached to said valves, and spring-stops applied on the sides of the draw-heads, as shown and described, whereby the springs are adapted to be engaged by the arm of the opposite draw-head, as set forth.
4:. In a hose-coupling, the combination, with a draw-head having a passage for connection With a hose, of a sliding pipe J, arranged in said passage, a spring for retracting the tube, a rotary valve working in contact with said pipe and having one side reduced, and an arm for operating the valve, substantially as shown and described.
5. In a hose-coupling, the combination of two draw-heads having passages adapted to register when the draw-heads are engaged, a sliding spring-actuated pipe arranged in each passage, and rotary valves having a reduced portion and provided with arms which come in contact and thus open the valves and force the pipes into close contact when the drawheads meet, substantially as shown and described.
6. A hose=coupling comprising a draw-head provided with a passage, a valve held in the passage, an arm extending from the said valve and adapted to be engaged by the arm of the valve on the opposite draw-head,and a spring I and stop H, attached to the draw-head 011 opposite sides of the valve-arm, which latter is adapted to be engaged by the arm of the Valve on the opposite draw-head, substan t-ially as shown and described.
