VALVE-CQNSTRUCTIION FOR PUMPS.
"Specification of Letters Patent. llpplicatldn filed January 12,1906. Serial Ho. 295.758-
Patented. April 23, 1907.
To all. whom zlt may concern:
Be it known that LJoHN ROWBOTH M, a citizen of the United States, residing in the city of Philadelphia, county-of Philadelphia,
State of Pennsylvania, have invented cer.
'tain new and useful Improvements in Valve Construction for Pumps, of which the following is a-specification.
This invention relates to a valve for pumps of theconstruction flin which the. valve is adapted to be lifted from its seat by the actionof the water or other fluid against its inner side, the said valve being returned, by
suitable means, to itsseat from which it was lifted by the action of the fluid,
The object of my invention is to provide means whereby when the valve islifted'i'rom its seat it is given a slight rotation so that it will return to its seat in a .slightly different position from that which it occupied before having. been lifted therefrom, and at the 7 same time materially reducing the component of the force of the water striking against 5 the valve, whichis exerted transversely of the lane of the valve.
' Tie purpose of rotating -or shiftingthe valve in this manner is to cause all'portions of the under or seat surface of the same to come into contact with the seat so that one portion thereof willnot be more greatly worn than another.
The purpose ofjmaterially reducing the component of the force of the water or other fluid against the said valve as it escapes through the valve mechanism is to decrease the number of breakages of the supports for the valves.
A further object of my inventionis to pro vide, means for facilitating the rotation of thevalve and the'mean's by which'the valve is held upon or against its seat.
- The objects andpurpo'sesfor which the invention is designed are effected by causing the travel of the water or other fluid through the openings or assageways provided in the valve seat'in suc directions that it will strike the valve at an acute angle, the result being that a certain component of the force of the escaping water occasions lifting of the valve,
while a certain other component of'suc force occasions the rotation or shifting of the valve; The relative proportions of these two components of the force of the escaping 1 water orfluid are dependent'upon the angle at which the said water or fluid strikes the valve asit escapes.
My invention-resides in the combination and arrangement or the parts as hereinafter described, specifically pointed-out in the claims, and as illustrated in the accompanying drawings forming apart of this specification, and in which,
Figure ,1 is a central vertical section'or" a valve and its seat taken along the line 1-1 of Figure 2.;
Figure 2 1s a top' lan view of the valve seat, a portion thereo being broken away;
Figure 3 is a sectional view showing the curved or bent deflecting 'lates or ribs, the upper edge of each of which overlaps-the lower edge of an adjacent plate or rib; and
' Figure 4 is avsimilar view showing curved or bent deflecting plates or ribs which d0 not overlap. I
The valve seat consists of what may be termed a hub 1, a ring 2, and deflecting plates or ribs 3 connecting the hub and ring,
as is clearly indicated in Figure 2 of the drawings. plane. of the valve seat and are curved or bent, as isclearly shownin Figures 1 aiid3 of the drawings. It is to be understood that any construction in which one or more por- The ribs 3 are inclined to the 8o tions of the respective plates or --ribs are angularly related to another portion or to other portions thereof, whereby eachof the said plates or ribs is concavo-convex in cross-section,.is within the scope of my-in-.
vention.
By inclining and curving the deflecting ribsin. the manner shown in Figures 1, 2 and upper edge ortions ofthe deflecting plates or ribs para el with the plane of the valve or the angularity may be made greater than is shown without departing from my invention.
It will be observed upon examination of Figures 2 and; 3, that the upper edge of each plate or rib..overlies. or overlaps the lower edge portion of an adjacent plate or rib.
The object of overlapping the plates or ribs in this manner is to prevent the passage of any portion of the water or fluid through the the case in the construction shown in Fi -1 to 3, inclusive, all of the said objectionable features areovercome,
The hub 1 is provided with a screwthreaded perforation 10 which is adapted to rece ve a screw-threaded end ofa projecting.
7 order to facilitate the rotation of the valve 4,
The bearing mechanism consists'of a-plate21i having a central perforation or opening 22 therein, throu h which the projecting bolt 11 passes. T e said plate 21 i s provided with a plurality of. openings 23- at points in:
termediate its outer circumference and the -said central perforation 22.
24 designates rollers mounted in these openings, the diameters of which rollers are greater than the thickness of the plate 21. It will thus be seen that, the Washer 20 and the nut 12 are in contact with the rollers andnot in contact with the plate 21, with the result that the force or pressure necessary to occasion rotation of the valve 4 and spring 15..
is greatly decreased.
1 Only two of the openings 23 and rollers24 are shown, but .it will be understood that there should be at least one more;opening and roller be rovided as are found tobe practicable an desirable. .It will be understood, of
course, that ball bearings may be substituted for the roller bearings shown.
