Application Ied'February 19, 1921, Serial No. 446,429. Renewed June 15, 1925.r
fo all lwhom t may concern: l
Be it known that I, LOUIE I". SMITH, ,a
Citizen of the United States,` residing at)- South Houston, inthe countyof Harris and State of Texas', have invented certa-in new and usefulv Improvements in a Pump, of 'which the following is' a specification.
This invention relates to new and useful improvementsa'n '-a pump. l
One object of the invention is to provide a pump of the character described embodying a casing, a driving shaft which is eccentric thereto,and on which an impeller blade housing is splined, saidjhousing carrying imv pellerblades which sweep around the walls of the fluid chamber within the casing and draw v'in the fluid through the intake lportv and drive it out through the discharge outlet. Y Another object is to provide a pump of very simple construction. so that'it may bel cheaply and easily manufactured and easily kept in repair.
` With the Iabove and other objects in view the invention has particular relation to certain' novel features of construction, operation and arrangement of parts,'an example of which is given this specification and illustrated in the accompanying drawings,
wherein Figure 1 is a vertical sectional view of the pump, and
igure 2 is a transverse sectional` View, an
Figures 3 and 4 show end and sectional view, respectively, of a housing employed.
In the drawings, .the numeral 1 designates a pump easin having the intake 2 and the discharge 3. he casing is formed with a fluid chamber 4 which is closed by the removable end platel 5. The other end of the casing is f rmed with a long eccentric bearing 6, wherein the drive shaft rotates. Withf in the chamber 4 there is aV circular housing 8 splinedon the inner end of the shaft 7. One end of this housing is formed of a circular plate which has an annular groove 9 v cut in its `outer face provided to receive an said shaft fits. Surrounding the bea-ring 11 are adjacent rings 12 and 13,' to] which the opposing impeller blades 14 and 15, respectively, are pivoted. These blades work radially through opposing slots 16 and l? in the housing 8. The outer edges` of these blades are -grooved lengthwise, said grooves continuing along the ends of the blades, and fitted into said grooves arethe'two-ply packing elements 18 and 19, preferably formed of soft metal or composition material soeas to form a close fit with the chamber walls but will not scar or unnecessarily wear said walls. The housing being eccentric in the chamber 4 will form a crescent shaped fluid chamber, as shown in Fi ure 2 and as said housing rotates with the s iaft 7 and around thebearing 11 the rings 12 and 13 will also rotate around the bearing 11 and carry the impeller blades 14 and 15 around the fluid chamber. As these blades sweep around through said chamber in close contact with the walls thereof a vacuum will be formed behind each blade which will cause the inflow of fluid through the intake 2 and the fluid in front of the blades will at the same time be forced out through the discharge 3. The end of the housing adjacent the end plate 5 is grooved to receive packing elements 20, 20 which form a close` fit against said end plate to prevent the passage of fluid to the interior of the housing.
What I claim is 1. A pum including a casing having an intake and ischarge, aremovable end plate forming one end of the casing and forming 4within the c asing a fluid chamber, a long eccentric bearing in the other` end of said cas` the removable end plate of the casing and formed with an eccentric socket into which the inner end of said shaft fits, opposing adjacent rings surrounding said inwardl projecting bearing, opposlng impeller lades pivoted to the respective rings and working radially through the slots of the housing, and means carried by the outer edges of the blades for forming a Water tight joint.
2. A pump including a casing having an intake and a discharge, a removable end pla-te forming one end of the casing and forming Within the casing a fluid chamber, a long eccentric bearing in the other end of said casing, a shaftrotatable in said bearing, a circular 'housing fixed on said shaft Within the casing and being provided with opposing slots, a circular plate formed with an annular groove in its outer face forming one end of said housing, an annular rib formed on the inner face of the adjacent end of the casing and fitting i'n said groove, an inwardly projecting central bearing carried by the removable end plate of the casing and formed with an eccentric socket into which continue along the ends of the blades,
packing in said grooves in the outer edges of said blades forming a close fit with the chamber Walls. i 1
In testimony whereof I havesigned my name to this specification in the presence of twosubscribing vvitnesseA LoUE F. SMITH.
