PATENT OFFICE.
ENEA 30881, OF
NEW YORK, N. Y.
DIAPHRAGM FOR LIQUID PUMPS.
Application filed May 28, 1924., Serial No. 716,514.
The present invention'relates broadly to diaphragms and more especially to diaphragms for liquid umps.
The principal ob ect of the invention is to provide a diaphragm which operates in correct proportion on the entire working surface.
Another object of the invention is to provide means whereby the resiliency of the diaphragm decreases towards the center.
Another object of the invention is'to provide means for the correct distribution of the stresses over the entire working surface of the diaphragm, thus reducing the breakage to a minimum.
Another object of the invention is to pro 'vide means on the diaphragm for obtaining the best possiblepumping efiiciency.
I attain these'objects by the designs illustrated in the accompanying drawing forming a part of this application and wherein similar numerals refer, to similar parts throughout the several figures thereof.
Realizing that the present invention. may be embodied in constructions other. than those specificall shown and described, I desire that the disclosure herewith shall be considered as illustrative and not in the a limiting sense.
Referring to the drawing: Figure 1 is a top viewof one form of the present invention, a
Figure 2 is a top view of another" form of the present invention, Figure 3 is a sectional View of Fig. ltaken on line II,
Figure 4 is a sectional View of Fig. 2 taken on line 11-11, and t Figure 5 is an elevational view of a diaphragm pump, partly shown in .section.
The invention illustrated in the drawing under Figures 1 and 3 consists of a disc 1 having corrugations 2. The said corruga tion are concentrically arranged and are interrupted by non-corrugated or iiat parts 3, the interruptions in one corrugation being disposed in staggered relation to theinter ruptions of the adjacent corrugations. The height of the corrugations increases the nearer they are located to thecenter. Referring to Figs. 2 and 4, the invention consists of a disc 1 having radial corrugations 4. The height of said corrugations increases towards the center. Referring to Fig. 5, the immotion will be transmitted over the entire working surface which results in high pumping efliciency and long life of the diaphragm. 7 Having thus described my invention, what I claim is:
1. A diaphragm for liquid pumps having a series of corrugations increasing in de th radially and means for actuating the 'aphragm connected thereto adjacent the corrugations of greatest depth, whereby the effort will be substantially uniformly distributed. f
2. A diaphragm for liquid pumps havin a series of corru ations increasin in depth radially toward t e center of the iaphragm and actuating means for the diaphragm connected thereto at about its center, whereby the effort will be substantially, uniformly distributed. 3. A diaphragm for liquid pumps havin corrugations increasing uniformly in dept siliency of the diaphragm is decreased toward its center and means for actuating the diaphragm connected thereto at about its center. 7 4. A diaphragm for liquid pumps havin ring shaped interrupted grooves, sai grooves increasing in depth towardsthe center of the said diaphra m.
5. A diaphragm for iquid pumps having concentrically arranged corrugations which are interrupted by non-corrugated parts, the interruptions in one corrugation being dis toward the center thereof, whereby the re I posed in staggered relationto the'interruptions of the adjacent corrugations, said corrugations increasing in heighttowards the center of the diaphragm.
a plurality of concentrically arran ed corrugations increasing in, depth radially towards the center, and means for actuating the diaphragm connected thereto at about I its center, forthe purpose described. I
100 I 6. A' diaphragm for liquid pumps having ENEAnossI.
