Description: Claim
1. In a hose coupling the combination of a valve casing having one end open and the opposite end closed, a pipe leading to the casing and communicating with the hose aforesaid, a main valve normally closing the said opener, a piston connected to the valve and valve controlled means for admitting fluid pressure from the pipe to the back of the piston, and for releasing such pressure from the back of the pressure to the atmosphere, as and for the purpose specified.
2. In a hose coupling the combination of a valve casing having its lower end closed and its upper end open, a pipe connected to the casing and communicating with the hose, a valve normally closing the open end of the casing, a piston carried by the valve and slidable within the casing, and depressible valve controlled means for admitting fluid pressure from the pipe to the back of the piston and for allowing the escape of said pressure from the back of the piston to atmosphere, as and for the purpose specified.
3. In a hose coupling the combination of a valve casing having an open top and closed bottom, a pipe opening to the casing and communicating with the hose, a valve normally closing the opening in the casing, a piston carried by the valve and slidable within the casing, a valve chamber adjoining the casing and communicating through suitable ducts with the interior of the casing beneath the piston and the pipe leading to the casing, said chamber communicating also with the exterior of the coupler through a suitable passageway, and valves controlling the passage of fluid pressure from the pipe to the back of the cylinder through the duct aforesaid, and from the valve casing beneath the piston to atmosphere through the passageway, as and for the purpose specified.
4. In a hose coupling the combination of a valve casing having a closed bottom and open top, a pipe leading from the casing and communicating with the hose aforesaid, a main valve normally closing the opening in the casing, a piston carried by the valve and slidable within the casing, a valve chamber adjoining the casing and communicating through suitable ducts with the valve casing beneath the piston and the interior of the pipe, there being a suitable passageway leading from the valve chamber to the exterior of the coupling, a depressible valve within the chamber controlling the passage of fluid pressure from the interior of the pipe to the interior of the valve casing beneath the piston through the ducts aforesaid, and a depressible valve located within the valve chamber controlling the escape of fluid pressure from the valve casing beneath the piston to atmosphere through the passageway, as and for the purpose specified.
5. In a hose coupling the combination of a valve casing having an open top and closed bottom, a pipe opening to the casing and communicating with the hose, a spring-pressed valve normally closing the open end of the casing, a piston carried by the valve and slidable within the casing, said piston being beneath the point where the pipe enters the casing, a valve chamber adjoining the casing and presenting an upper and a lower valve seat, there being ducts leading from the valve chamber to the interior of the valve casing beneath the piston and from the valve chamber to the interior of the pipe aforesaid, and a passageway leading from the valve chamber to the exterior of the coupling, a depressible valve adapted to seat on the lower valve seat and controlling the passage to fluid pressure from the interior of the pipe to the valve casing beneath the cylinder, and a depressible valve adapted to seat on the upper valve seat, and controlling the escape of fluid pressure from the valve casing beneath the piston to atmosphere through the passageway aforesaid, said valves within the valve chamber being connected so that one is seated whist the other is unseated, as and for the purpose specified.
6. The combination with a pair of engageable couplers connected to suitable pressure hose and provided with normally closed valves preventing escape of pressure from the hose, of means actuated by the act of coupling the couplers designed to open the valves of the couplers and allowing pressure to escape from one coupler to the other, as and for the purpose specified.
7. The combination with a pair of engageable couplers connected to suitable pressure hose and provided with valves held normally closed by the pressure in the hose, of means actuated by the act of coupling the couplers for releasing to atmosphere the pressure aforesaid, holding the valves closed, as and for the purpose specified.
8. The combination with a pair of engageable coupler heads, each connected with a suitable pressure hose and provided with a suitable valve casing having a closed bottom and an open top, valves within the casings and adapted when seated to close the openings in the casings, pistons carried by the valves being held normally closed by the action of fluid pressure on the pistons, of depressible means actuated by the act of coupling the hose and adapted to release to atmosphere the pressure aforesaid from the pistons, thereby unseating the valves, as and for the purpose specified.
9. In a hose coupler the combination of a valve casing having an open top and closed bottom, a pipe opening to the casing and communicating with the hose, a valve within the casing adapted to close the open end thereof, a piston carried by the valve and slidable within the casing, a spring engageable with the under face of the piston and the base of the casing, a valve chamber adjoining the casing and presenting an upper and a lower valve seat, there being a duct leading from beneath the lower valve seat, to the interior of the pipe, and a duct leading from the above the lower valve seat to the interior of the valve casing beneath the piston, and further a passageway leading from the top of the valve chamber to the exterior of the coupling, a spring-pressed valve in the form on a socket slidable within the valve stem passing through the passageway and projecting beyond the face of the coupling, a valve carried by the stem and designed to seat on the upper valve seat, a plunger extending downwardly from the latter valve and into the socket, a spring interposed, between the end of the plunger and the base of the socket, and a pin carried b the socket and passing through a suitable slot formed in the plunger, as and for the purpose specified.
