April 19, 1932. v. TANNEHILL PUMP Filed NOV. 22, 1930 Patented Apr. 19, 1932 UNITED STATES P TENT OFFICE VERNON L. TANNEHILL, 013 FORT WAYNE, INDIANA, ASSIGNOR TO FORT WAYNE EN- GINEERlNGrAND MANUFACTURING COMPANY, OF FORT \VAYNE, INDIANA PUMP Application filed November 22, 1930. Serial No. 497,466.
This invention relates to improvements in pumps. 4 r
One ofthe objects of the present invention is to provide an improved pump which is simil lar and preferably an improvement on that type of pump illustrated in Patent #121,196,- 920, patentedSeptember 5th, 1916; and to provide a pump of this character which is of the double actingtype.
Another object of the present invention is the'provision of a double acting type of pump having a singlecylinder shell in which a reciprocative piston is mounted, together with check valves adapted to be alternately operat- 15 ed upon reciprocation of the piston for permitting the passage of fluid into the pump cylinderor shell, and alternately discharging the same from opposite ends of the shell to a single outlet.
With the above and other objects in view, the invention consistsinthe novel features of construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claims and shown in the accompanying drawings wherein In the drawing, there is illustrated in sectional View a pump constructed in accordance with my invention; and referring more particularly to the drawing, 1 indicates the main housing of my improved pump, closed at one end by means of a head 2, bolted or otherwise attached to the ears 3 on the housing 1. The head 2 carries a bearing sleeve 4 in which the piston rod 5 is slidably mounted and retained in position by a plurality of packing rings 6.
It will be noted that the ends of the housing 1 are provided with central openings, the head 2 carrying a ring 7 which is fitted in the open ing in one end of the housing. A valve housing 8 is arranged at the other end of the main housing 1 and has an inwardly projecting bearing portion 9 which extends through the opening in the other end of the housing 1 and has a valve seat'lO at its inner end.
The head 8 also carries a sleeve 11 adapted to extend into a chamber A at one end of the housing. The valve housing 8 is detachably connected to the end of the housing 1 by means of the bolts 12.
The valve housing 8 is formed with a main chamber 13 and leading into each end of this chamber are the threaded inlet portions 1s: adapted to be connected up with a source of fluid supply. At right angles to the threaded portions 14 are the inlets '15 which may be used in place of the inlets 14,-but when the portions 1 1 are in use, the inlets 15 are closed by means of the threaded plugs 16.
Arranged centrally within the housing 1 is a cylinder 17 having an inner shell 18- in which the piston 19 reciprocates, said piston being removably connected to the inner end of the piston rod 5. This cylinder 17 is supported in equal spaced relation with the Wall of the h ousing 1 by means of connecting arms 20, arranged at various points between the cylinder and the housing and preferably circumferentially of the cylinder. The ends of the shell and the cylinder are beveled off as shown at 21, and the inner ends of the ring '7 and bearing 9 are beveled, as shown at 22, to correspond with the beveled portions on the cylinder '17 and shell 18.
The ends of the shell and cylinder are spaced from ring 7 and sleeve 9 to provide annular passageways 23 and 23 at the ends of the cylinder.
Arranged at each end. of the cylinder are the expansible rings 24 and 24', which close the passageways 23 and 23, as shownin the drawing, but under fluid pressure, these rings 24 and 24 will expand and permit fluid to flow through the passageways into the chambers B and C, and cause the fluid to flow out through the threaded outlet 25 which is arranged at one side of the housing 1.
The outer end of the sleeve 11 is provided with a valve seat 11 and arranged in the passageways 26 and 26, which connect the chamber 13 with chambers A and C, are the bearing sleeves 27 in which are mounted the valve rods 28 carrying valves 29 and 29, valve 29 normally engaging the seat 10, while valve 29 normally engages seat 11, thus cutting off any communication between chamber 13 and chambers A and C.
The valves 29 and 29' are normally maintained in closed position through the medium of coil springs 30 mounted'on the valve stems 28, and positioned between the bearing sleeves 27 and the retaining nuts 31 at the outer ends of the valve stems. From this, it will be apparent that the tension of springs 30 will normally maintain the Valve members 29 and 29 in a seated position.
In the operation of my improved pump, it will be readily noted that when the piston head 19 moves forwardly, in shell 18, the suction of the piston head in the shell will cause the valve 29 to be opened permitting the passage of fluid from chamber 13, into chamber A through conduit 32 and into one end of the shell 18.
However, as soon as the piston has reached the limit of its inward stoke and begins a return or outward stroke, the valve 29 will be closed, and valve 29 will be moved to an open position through the suction created by the piston head in the shell. As the piston moves outwardly, or is moved on its return stroke, the fluid drawn into one end of the shell will be forced out through the passageway 23, expanding ring 2 1 and discharging the fluid pressure into chamber 13, where it is conveyed out through the outlet opening 25.
It will be apparent that as the pump continues to operate and the piston head 19 moves outwardly again in the shell, the valve 29 will be closed and valve 29 will be opened, while the fluid in front of the piston head 19 will be forced out through the passageway 23, expanding valve ring 24 to discharge the fluid into chamber G, where it will be carried off through the outlet 25. From the above, it will be apparent that through the reciprocation of the piston, fluid is drawn from the chamber 13, either past valve 29, or valve 29', and alternately taken into the ends of the shell 18, where it is discharged through the passageways 23 and 23, past expansible valve rings 24: and 24' to be carried out through the outlet 25in the main housing. Attention is directed to the fact that in the operation of this type of pump, a great deal of fluid can be pumped through the housing upon a single stroke of the piston and increases the volume of fluid passing therethrough over the type of pump illustrated in Patent No. 1,196,920, and is believed to be a great improvement thereover.
In view of the simplicity in the construction of a pump of this character, it is believed that the same will prove of great value, as it can be manufactured at a very low cost, and will prove very effieient for the purposes intended, not only as to the increase of volume of fluid passed therethrough, but due to the compactness and arrangement of the parts of the pump which permits the same to be readily taken apart or put together, and also permits the ready replacement of any broken or worn out parts.
While I have shown and described the preferred embodiment of my invention, it Will be apparent from the foregoing that slight changes may be made in the construction when putting the invention into practice without departing from the spirit of the same or the scope of the appended claim.
I claim:
In a double acting pump, a pump housing having a longitudinally extending passageway disposed at one side of its longitudinal axis, a pump cylinder in said housing spaced from the wallsof the housing and having its opposite ends bevelled to form a seat, a head secured to one end of the housing having an annular guide protruding into the housing and having its inner face bevelled to form a seat, the passageway communicating with the cylinder through said annular guide, a valve housing secured to the opposite end of the first housing and including a pair of spaced guide sleeves, one of said sleeves extending axially into the housing and having a bevelled valve seat on its inner face, the other sleeve extending into the passageway, springpressed check valves mounted in said sleeves and opening inwardly toward the cylinder and passageway, expansion valve rings disposed between the ends of the cylinder and the valve seats formed on the annular guide and the sleeve disposed in axial alignment with the pump housing, the valve housing having an inlet, and the pump housing having an outlet, and a piston reciprocatively mounted within said cylinder.
In testimony that I claim the foregoing I have hereunto set my hand.
