MAX C. MASON, OF KEENE, NEW HAMPSHIRE.
ROTARY PUMPQ Application filed January 5, 1922. Serial No. 527,234.
To all 'whom t may concern:
Be it known that l, Max C. MASON, a citizen of the United Sta-tes of America, and a. resident of Keene, in the county of Cheshire and State of New Hampshire, have invented certain new and useful improvements in Rotary Pumps, of which the following is a specification.
This invention relates to rotary pumps and has for its object the production of a pump which is simple in construction, effective in operation, and which is particularly adapted for use in pumping liquids.
The invention consists in a casing having a chamber in which are rotatably mounted two disks on opposite sides of a stationary camshaped member and between which are mounted a plurality of blades, one end of each of which is pivoted to one disk while the opposite end is pivoted to the other disk, said disks being so constructed as to continuously close a restricted path therefor between the inlet and outlet passages of said casing.
The invention further consists in certain novel features of construction and arrangement-of parts which will be understood readily by reference to the description of the drawings and to the claims to be hereinafter given.
For the purpose of illustrating the invention, one preferred form thereof is shown in the drawings, this form having,` `been found to give 'satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and that the invention is not limited 'to the precise arrangement ,and organization of the instrumentalities as here in shown and described, except as required by the scope of theappended claims.
Of the drawings:
Figure 1 represents a longitudinal section of a pump en'ibodying the principles of the present invention.
Figure 2 represents an elevation of the same with the enclosing plate removed, and
Figure 3 represents a transverse section of same on line 3, 3 on Figure 1.
Similar characters indicate like parts throughout the several figures of the drawings.
In the drawings, 1() is a casing having at one end a hub 11, in which is disposed a rotatable shaft 12. The outer end of the hub l1 is provided with a stufling box 13 of usual construction. The inner end of the shaft 12 has keyed, or otherwise secured thereto a disk 14. The opposite end of the casing 10 is formed open and is closed by means of a plate 15 secured to the casing 10 by means of bolts 16. The plate 15 has mounted therein and keyed thereto a stud 17, the inner end of which has keyed, or otherwise secured thereto, the stationary oam-shaped member 18. n j
One face of the stationary cam-shaped member abuts one face of the disk 14, and between the opposite face of said camshaped member 18 and inner wall of the plate 15 is disposed a second disk 19,freely revoluble about the stud 17.
As shown in Figure 1 of the drawings, the axes of the shaft 12 and the stud 17 are out of alinement with each other, and they are also out of alinement withthe center of the chamber 20 in the casing 10. This casing 10 is provided with two passages21, communicating with, the chamber 20 and `either of which may beused as an inlet passage, while the other is used as an outlet or discharge passage.
Between these passages 21, the inner wall of the casing 10 is provided with a camshaped projection 22 extending inwardly. toward the center of the chamber 20. In like manner the cam-shaped stationary member 18 is provided with a projecting portion 23 extending toward said projection 22, thereby forming a narrow restricted path between said projections 22 and 23 at a point midway between the inlet and outlet passages 21.
Each disk 14 and y19 has concentrioally disposed thereon and securedv thereto the bearing pins 24 and 25, the bearing pins 24 being mounted on the disk 14 and extending toward the disk 19, while the bearing pins 25 are secured to the disk 19 and extend toward the disk 14.
Each bearing pin 24 extends through a cylindrical opening in one end of ay blade 26, while each bearing pin25 extends through a cylindrical opening in the opposite end of a blade 26.
These blades 26 are so shaped as to contact with the walls of the projections 22 and 23 as they pass through the narrow passage between these projections, and there are within the chamber 20 a sufficient number of blades 26 to permit the narrowpath between the projections 2Q and 23 being always closed by at least one blade being positioned therein duringv the rotation ot the shalt l2. In other words, a median line extending` transversely ot each blade ft will have a length equal to the width ot the said path at its narrowest point and the thickness ot the blade on any line on either side et said median line and parallel thereto will also be equal to the width of said path at its narrowest point.
It the lower passage 21 is used as an inlet passage, the material being` pumped will enter the chamber 20 in the direction of arrow (t on Figure 3, and the rotatable disks M and 19 will be rotated in the direction orn the arrow Z; on lligrure l oi said drawings.
As the blades E26 more downwardly in the rotation el said disks 11i; and l), they will cut through the material and torce it ahead of the blades 26 until the material is discharged through the upper pa ge 21. as in the rotation ot the disks and 1t) the narrow path between the 'projections and 23 is closed by one or more blades 2G therein, it is obvious that the material being' pumped cannot return to the intake passage 21, atter following-the course of the blades about the stationary cam-shaped member 18.
It is self-evident that in the operation of the pump the blades 26 will remain substantially in parallelism at all times.
The pins 2-1- are preterably provided with reduced threaded ends 27, which extend through the disks le and 19 and have mounted thereon the clamping nuts 28.
It is obvious, however, that these pins may be secured to the disks in any well-known manner, provided that they are concentrically disposed upon the disks and parallel to each other and to the driving` shaft 12.
The disk 14 rotates in a recess 29 formed in the casing 10, at one side oit the chamber 20, while the disk 19 rotates in a similar recess 30 formed in the inner wall ot the closing plate 15 on the opposite side of said chamber 20.
This makes a very simple 'term o't pump which may be easily maintained in working order at all times.
It is believed that the operation and many` advantages Aof the invention will be readily understood without Jfurther descrip-I tion.
Having thus described my invention, I claim:
