A. s. MARLOW PUMPING MECHANISM Filed July 1925 patented Nov. 23, 1926.
llhll'l'E STATES ALFRED S. MARLOW, OF LINCOLN PARK,.N'EW JERSEY.
PUMPING MECHANISM.
Application fil d July 20, 1925 Serial No. 441258.
This invention relates to pumping mechanism and more particularly it relates to diaphragm pumps.
An object of this invention is to provide an improved valve arrangement for a pui'np.
3 second object of the invention is to pro vide an improved ball valve for a diaphragm pump. Other objects will be apparent from the detailed description of the invention hereinafter given.
The specitic form of this invention which has been chosen for illustrative purposes resides in the ball valve chamber of a diaphragm pulp. In such a pump it is custonr,
my to provide a ball which in one position closes an inlet opening, and in a second position is removed from the inlet opening a sufficient distance to enable water or other fluid to pass into or out of: the pipe, the ball alternately between these two positions under the operation of the diaphragm. In accordance with. this invention guiding; means integral with the inner walls of the valve chamber are provided for limiting the ball to a definite path between its two manimum positions while insuring that the ball will always tightly close the inlet opening at the proper time. As the pump of this invention is especially intended to handle raw sewage which normally contains rags, hair, string and other solid matter the interior oi the ball valve chamber along with the guiding means is fashioned in such a manner as to reduce to a n'iinimum the presence oi sharp projections which would tend to *atch and hold rags, string or other solid matter in the water and cause the valve chamber to become clogged and consequently inoperative.
This invention will be better rmderstood by reference to the "following detailed description taken in connection with the accompanying drawings in which Fig. 1 is. a sectional view of this invention applied to a diaphragm pump Fig. 2 is a top view ot the same also in section; and
Fig. 3 illustrates how the cover 01" the hall chamber of the pump may be hinged.
Referring to the drawings, more particularly to Fig. l, a portion of a diaphragm pump is disclosed'in sufficient detail to describe the invention. The usual flexible diaphragm 3 is shown at the upper part oi a horizontal chamber l. The edges of the diaphragm are suitably clamped as shown at the point 5, whileat the center of the dies phragm the rod or arm (not shown) rom crating the diaphragm is suitably fastened tothe two plates 6 and 7 located on opposite sides of the "diaphragm. The diaphragm chamber 4 is suitably connected by a short pipe 8 to the valve chamber, 9. 'lhe cham? ber 9contains a ball valve comprising ai'b'all 10 which in its lowermost positionis designed to completely close the valve seat 20- which constitutes the upper end of an inlet pipe 11. It'wilh of course, be understood that when diaphragm 3 is in its lowermost positionfthe ball'lO will be'lirml'y' seated, on. the valve seat 20, while thcmovement of dia? phragm 3 to its upper position will by sue} tion cause liquid in pipe 11 to liftball l O' away from the valve seat 20. and allowqthe liquid to flow through pipe '8 into the dia phragm chamber/l. The return of thedia phragm 3 to its lower position will cause ball 10 to close pipe 11 again so that the liquid in chamber l. will be forced on beyond the chamber 4i to any suitable outlet or res? ervoir. It will, of course, be understood I that if desired another ball valve maybe provided between the chamber and. the outlet which will be opened when the die: phrag'in 3 is being pushed dowiiwardlyfto,v force out the water.
In'the upward and downwardmovement of the ball 10 corresponding tothe operation of diapl'iragm 3, it is essential that itspath be clearly defined so as to limit the sidewise motion of the ball and insure its return each time in such a manner as to secure the. prompt closingot pipe 11. In. accordance with this invention, a plurality" oil vanes 13 to 18 are provided for. this purpose. These vanes are integral with the inner walls lot the chamber 9 and serve-to form auohanncl, in which the ball lOmay rise and fall. As, shown more particularly in. Fig. 2,"the six vanes are spaced on op'positesides'oif theball and are of such shape as to offer little opposition, tothe flow of the water from pipe 11 up and around balllO andout pipe 8, the directionof flow of the water being indicated by the arrows. It will also be noted by an examination of Fig. 2 that considerable side play of the ball 10 is permissible in spite of the vanes. The amount of side play, however, should not be sufficiently great to endanger the complete and prompt closing of pipe 11 each cycle.
The type of ball valve and chamber just i so Hit
described is particularly adapted for use in pumps intended to work with water containing an appreciable amount of solid matter and sediment, such as sewage containing rags, hair, string, etc. The entire interior of the ball chamber 9 is designed to present only smooth surfaces to the flow of the dirty water and consequently there is a minimum opportunity offered for the catching or deposit o1 solid matter in the ball chamher. It should be particularly noted that the vanes 13 to 18 are rounded oil smoothly on all sides so as to offer no sharp projections in the path of the water flow. Also the vanes are of comparatively short length, extending along the side walls for a length less than the radius of ball 10. It should also be pointed out that there are no projections located between the ball and the cover 19 oi the ball chamber, so that there is a tree paisage for the water above the ball. The cover 19 may be made removable in any desired manner so that the ball valve may be periodically inspected. The character of the ball chamber just described is such that the cover 19 may be h nged to the main part of the pump, thereby enabling the ball chamber to be readily opened wltnout any danger of having the cover castaside in the dirt by careless workmen as would be possible with an unhinged cover. It is, of course, important that the ioint between the eover and the ball chamber should be clean and air tight.
One manner in which the cover 19 may be hinged is illustrated in 3, wherein the cover 19 is shown pivotly connected at the point 21 with an acute angle member 22 which is hinged at one end to the point 23. T he other end is slotted to receive. a threaded rod 25 h nged at the point 24. A nut 26 may be screwed down on red 25 against member .22 whereby an air tight jointmay be secured between cover 19 and the walls of chamber 9.
This type of ball chamber has been found by actual experiment to give far more satisfactory results than tvpes heretofore employed for the pumping of dirty water which tends to render the ordinary ball valve inoperative due to the accumulation of dirt caught by any sharp projections in the ball chamber.
lVith the exception of the ball chamber described above, the pump may be constructed in any well-known manner and size ing water containing a large amount oi solid matter and comprising a chamber, a ball in said chamber, an intake at the battom of said chamber, said intake closed at times by said ball, said ball being adapted to be periodically lifted from aid intake whereby water from said intake may be forced into said chamber, an outlet for said chamber, and a pluraltiy of elongated ridges spaced around said ball and integral with the walls of said chamber for guiding said ball, said ridges being parallel to each other and parallel to the direction of movement of said ball, said ridges being smoothly rounded on their sides and ends and other surfaces to offer no sharp projections in the water passage, the remainder of the interior of said chamber being free of sharp PlOJQC tions which would tend to impede the passage of solid matter in the water being pumped. 7'
2. A ball valve for a diaphragm pump comprising a chamber, a ball in said chamher, a pipe forming a part of the bottom oi said chamber, the end of said pipe bei closed at times by said ball, said ball bein adapted to be riodically lifted from said pipe, whereby water from said pipe may be forced into said chamber, an outlet for said chamber on one side thereof, and ertical parallel vanes on two of the remaining sides of said chamber for guiding said ball, d vanes being smoothly rounded on their sid and ends to orler no share projections in by: water passage, the remainder of the interior of said chamber being free of sharp project ons which would tend to impede the passage of solid matter in the water being pumped.
In witness whereof, I hereunto subscribe my name this 14: day of July A. D., 1925.
ALFRED S. MARLOW.
