ROTARY PUMP Filed March 5. 1929 INVENTOR Y t/O/WY "C 67rd A 17' ORNE 1T Patented July 5, 1932 UNITED STATES PATENT OFFICE JOHN G. BIRD, OF BATTLE CREEK, MICHIGAN, ASSIGNOR TO UNION STEAM PUMP COM- PANY, OF BATTLE CREEK, MICHIGAN ROTARY PUMP Application filed March 5,
The objects of the invention are:
First, to provide an improved form of rotor projection and passage for insuring high efficiency.
Second, to provide an improved abutment structure.
Objects pertaining to details and economies of construct-ion and operation will definitely appear from the description to follow. A preferred embodiment of my invention is illustrated in the accompanying drawing, in which:
Fig. 1 is a side elevation of the pump from the suction side.
Fig. 2 is a longitudinal end sectional elevation on line 22 of Fig. 3 also from the suction side.
Fig. 3 is an end elevation from the left of Figs. land 2 with discharge cover removed. f showing the form of the rotor and its periphery and relation to the abutment.
Fig. 4 is an enlarged sectionalview on irregular line H of Fig. 3 showing the close fit of the abutment rotor and the projections.
Fig. 5 is an enlarged detail section on line 5-5 of Fig. 4 showing the form of projections on the rotor and relation to the abutment member.
Fig. 6 is a detail perspective of the abut- I so ment structure and its relation to the chamber and case.
The parts will be identified by their numerals of reference.
1 is the base. 2 is the shell of the pump supported on the base. 3 is the intake connection opening into the hollow cylindrical chamber 4: at port 31. The rotor 5 is in the form of a spoked wheel carried on the'pump shaft 6 which is supported in suitable bearings 7 7. The rotor is provided with a heavy rim 51 provided with alternate radial rectangular-ended tooth-like projections of different lengths, 52, 53. The elongated projections 53 are rectangular in cross-section, with their outer ends broader than their inner ends, this being accomplished by placing the front and rear faces of the projections in radial planes.
The longer projections 53 coact with the abutment 8 which has a segment 81 concentric 1929. Serial No. 344,243.
As the outer ends of the projections 53 are a close fit to the abutment 8, the fluid cannot pass at that point andis forced at strong pressure out through discharge port 101 to the discharge 10.- The form of the rotor and its coaction with the abut-ment close fitting thereto insure very high efiiciency.
I have shown both the long and short pro jections with rectangular ends and radial faces. I have shown the abutment in the pre ferred form. I desire to claim the structure because of its peculiar eiiiciency specifically and I also desireto claim the same broadly to the extent indicated in the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In a pump of the class described, the
combination of a pump casing, a cylindrical a chamber having an intake port opening into the periphery of said chamber, a rotor wheel with a heavy rim filling the said casing and with rectangular ended projections of alternate different height at its periphery, the higher of which conform to the peripheral wall of said chamber and are spaced therefrom for engaging and advancing the liquid being pumped, the forward faces of the higher of said projections being in radial planes,
a cover plate with discharge connection disposed to connect to said discharge port.
2. In a pump of the class described, the combination of a pump casing,'a cylindrical chamber having an intake port opening into 7 the periphery of said chamber, a rotor wheel with a heavy rim filling the said casing and with rectangular-ended projections of alternate different height at its periphery, the higher of which conform to the peripheral wall of said chamber and are spaced therefrom for engaging and advancing the liquid being pumped, the forward faces of said proje-ctionsbeing in radial planes, a segmental abutment on an arc concentric with the periphery of said chamber on a detachable plate in said casing and of suflicient length to subtend at least two of the said longer projections and conforming to the ends thereof, a
. discharge port in advance of said abutment,
and a cover plate with discharge connection disposed to connect to said discharge port.
3. In a pump of the class described, the combination of a pump casing, a cylindrical chamber having an intake port opening into the periphery of said chamber, a rotor wheel with a heavy rim filling the said casing and with rectangular-ended projections of alternate different height at its periphery, the higher of which conform to the peripheral wall of said chamber and are spaced therefrom for engaging and advancing the liquid being pumped, a segmental abutment on an arc concentric with the periphery of said chamber on a detachable plate in said casing and of sufficient length to subtend at least two of the said longer projections and conforming to the ends thereof and closely engaging the same, a discharge port in advance of said abutment, and a cover plate with discharge connection disposed to connect to said discharge port.
4. In a pump of the class described, the combination of a pump casing having a cylindrical chamber, and having an intake with a port opening into theperiphery of the said chamber, a rotor wheel disposed within said casing and having heavy rim and rectangular-ended tooth-like projections alternately of different height at its periphery, the higher of which conform to the peripheral wall of said chamber and are spaced therefrom and with radial front faces for engaging and advancing liquid, an abutment within the said chamber with an arc concentric with the periphery thereof disposed and arranged to closely engage the ends of the said longer hand.
