PUMP.
Specification of Letters Patent.
Patented Aug. 14, 1917.
Application filed August 22, 1916. Serial No. 116,272.
To all whom it may concern:
Be it known that I, DANIEL WV. REDDIN, J12, a citizen of the United States, residing at North Baltimore, in the county of 00d and State of Ohio, have invented certain new and useful Improvements in Pumps; and I do hereby 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.
This invention relates to pumps used for pumping water containing sand out of wells; and it consists of a trap for the sand at the lower end portion of the pump as hereinafter fully described and claimed.
In the drawings, Figure 1 is a front view of the lower end portion of a pump constructed according to this invention and showing the door of the sand trap closed. Fig. 2 is a side view of the same showing the door open, and showing also a portion of the discharge receptacle in section. Fig. 3 is a longitudinal section through the inlet valve, taken on the line 00-02 in Fig. 4:. Fig. 4 is a cross-section, taken on the line 'y-y in Fig. 2.
The inlet pipe 2 of the pump is formed of a continuation of the pump barrel, and a pump plunger 3 of any approved construction is slidable in the pump barrel. The inlet pipe 2 has an opening A in one side close above the inlet valve or foot valve 5. This opening 4: has a door 6 which is hinged at its upper end by a pivot pin 7 to the pipe, and which opens outwardly. The hinge is arranged inside the pipe so that no projection is formed on its outer surface, and the door is arranged to fit snugly over the opening 1 so that the premature escape of water and sand is prevented. The door 6 closes by gravity, and is thicker at its lower end than at its upper part.
The inlet valve 5 is of any approved construction, but it is preferably what is known as a turtle backed valve. Its seat 8 is secured in the pipe 2 below the opening 4:, and the valve is arranged diagonally of the pipe with its lower end pivoted by a pin 9 to the valve seat.
The angular or turtle backed shape of the pivoted valve enables it to open wider in the cylindrical pipe, and its inclined position causes the sand which accumulates on it to press by gravity against the lower end portion of the door 6. The valve 5 has a stop 10 on its upper end to prevent it from opening too far.
A ring 12 is arranged to slide by gravity over the pipe 2 and the door 6, and when lowered, as shown in Fig. 1, this ring holds the door closed. A stop 14L is secured to the pipe 2 on the opposite side of it from the door for the ring 12 to rest on when in its lowest position. The ring 12 is provided with a bayonet slot 15 at its lower edge for engaging with a pin 16 which projects from the door or from the pipe. When the ring engages with this pin and has been moved around a little circumferentially the ring is locked against vertical movement, as is sometimes desirable. The ring can be moved circumferentially by any suitable wrench which engages with holes 17 in the ring, or on occasion it can be operated by hand. The bottom of the pipe 2 is provided with teeth or projections 18 which rest on the bottom of the well.
A guard ring 20 is secured to the pipe 2 above the level of the door 6, and it proj ects laterally around the pipe for a greater distance than the ring 12, and prevents the ring 12 from coming in contact with the side walls of the well.
When the pump is at work, the pipe 2 is lowered in the well, and the door 6 is held closed by the ring 12, which may be locked in position if desired, before the pipe is lowered. The pump plungerraises the water and sand in the usual way, and when sand has accumulated in the sand trap on top of the inlet valve 5, the pump is raised out of the well.
When the pump has been raised out of the well it is lowered into any suitable receptacle 24.- the top of which is provided with a hole or ring having projections 25. The lower end of the pipe 2 slides between these projections and the ring 12 rests upon them so that the door slides downwardly out of contact with the said ring. The door is then opened automatically by the pressure of the sand and water against it, and the sand and water are dumped into the receptacle 2 1. This sand trap does not become plugged up with sand, and it dumps automatically from its lower end and without being inverted. This pump is specially designed for use in the oil field for cleaning out wells which are being drilled.
What I claim is:
1. In a pump, an inlet pipe provided with an inlet valve and having an opening in one side above the inlet valve, a hinged door for closing the said opening, a ring slidable by gravity on the said pipe and door and normally holding the door closed, and means for sliding the ring out of engagement with the door.
2. In a pump, an inlet pipe provided with an inlet valve and having an opening in one side above the inlet valve, a door for closing the said opening, said door having a hinge at its upper end arranged inside and connected to the said pipe, a ring slidable by gravity on the said pipe and door and normally holding the door closed, a stop on the pipe limiting the movement of the ring in one direct-ion, and means for sliding the ring in the reverse direction to release the door.
3. Ina pump, an inlet pipe provided with an inlet valve and having an opening in one side above the inlet valve, a hinged door for closing the said opening, a stop secured to the said pipe, a ring slidable on the pipe and holding the door closed when resting on the said stop, a locking device for preventing the ring from sliding longitudinally on the pipe, and means for sliding the ring Copies of. this patent longitudinally to release the door when dis engaged from the locking device.
4. In a pump, .an inlet pipe provided with an opening on one side, a door hinged at its upper end to the said pipe and normally "closing the said opening, an inlet valve arranged diagonally inside the pipe with its lower end pivoted adjacent to the bottom end of the said opening, a ring slidable by gravity on the said pipe and normally holding the door closed, and means for sliding the ring longitudinally of the pipe to release the door.
5. In a pump, an inlet pipe provided with an inlet valve and having an opening in one side above the inlet valve, a hinged door for closing the said opening, a ring slidable by gravity on the said pipe and door and normally holding the door closed, a guard ring secured to the pipe above the said door and projecting laterally around the slidable ring, and means for sliding the slidable ring longitudinally on the pipe to release the said door.
In testimony whereof I have aflixed my signature.
