Speeiication of Letters Patent.
Ijatentedct. 10, .1911.
Application led September 24, 1910. Serial No. 583,600.
To all 'whom it may concern:
Be it known that I, EDWARD L. HARPER, J r., a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have'invented a neriv and Improved Pump, of which the following is a full, clear, and e-xact description.
Among the principal. objects which the present invent-ion has in view are: to provide means for correcting the swirling of the water within the barrel cfa pump, and in the delivery column thereof; and to provide in a rot-ary pump devices for correcting the swirling o-f thewater as and when the 'same is delivered from the various blades or fins.
One embodiment of the present invention is disclosed in the structure illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a longitudinal vertical section of a pump constructed and arranged in accordance with the-presentl invention; fig. 2
. is a side view of a propeller blade an liub therefor, constructed in accordance with the present invention; and Figt is a side view of a swirl preventing device constructed in accordance with the present invention.
The present invention is shown as applied to a pump of usual construction, wherein is employed a` bed plate 8. On the bed plate 8 is mounted a bearing pedestal 9 and an inlet head 10. A driving shaft 11 is mounted in bearings I12 and 13, constructed in any approved manner, and as is usual in pumps of this character, and is provided with a driven pulley 14 at one end, suitably connected with any source of power.
Extended from the pedestal 9 are brackets l 15 and 16 which support a delivery pipe 17.
The' delivery pipe 17 and the inlet head 10 are provided with bolting ianges between which is extended a pump barrel 18. It is through the pump barrel 18 that the shaft 11 is extended, and within which it is provided with a series of propeller screw sections 19, 19. The screw sections 19, 19 are provided with semi-circular screw blade sec- 1 ions 20, 20. The pitch of the blade sections 20, 20 is suliicient to extend each blade sec tion from one to the other end of the hub of each of the sections 19. Eachof the blade into the shaft 11.
nterposed -between-each of the sections -19 is a battling section 22. The baffling sections 22, 22 equal in' number the screw scc.- tions 19, andare provided with semi-circun lar screw blades 28, 23. The blades 23,23:
are extended at a itch directly.v the opposite of the pitch of tli'e blade sections 20.` the pitch in both the blade sections 20 and 23 being equal. .The battling sections 22, '22 are loosely mounted on the shaft 11, being guided and held thereon by the sections-19. The end section 22 is held in position on the shaft 11 by a rtainine collar 24.
In the operation of a pump when constructed as shown in the accompanying drawings, and as above described, the water received from the inlet head 10 is advanced by the blade sections 20, 2() of the rst of the series of screw sections 19. F rom the first of the screw sections 19 the water is delivered against the oppositely pitched blade sections 2?y of the battling sections 22. In passing through the first of the baffling sec` tions 22 to the second of the screw sections 19, the swirl or gyration imparted to the column of water by the screw sections is corrected. It is found that the rotaiar force of the water as delivered by the blade 19 is equal to the force required to rotate the section 22. Thel gyrative force of the water as delivered from the sections 19 is required to rotate the baffling sections 22. The resistance of the sections 22 is suicient only to straighten the line of travel of the water through the pump barrel 18. It will be understood that the resultant effect of this action is to straighten the path of travel of the water due to the yielding of the blade sections 23 from the straight path of the water and the resistance thereof to the path of gyration of the said water as delivered from the sections 19. The effect of the delivery of the water by each of the screw sections 19 is to rotate the baffling section drectly in front yof each of the said screw sec tions. The retardation of the columnv'of water after delivery from the screw section limiting myself to such construction.
19 is very slight by reason of the fact that the friction on the battling sections 1s minimized.
It Will be understood that as many couples comprising a screw section and a baffling section may be employed in these pumps as the requirements demand. At the end of the barrel 18, Without reference to length, the Water is delivered past the nal baffling section 22 into the delivery pipe 17, to be from thence delivered into a. discharge pipe 25. i
While I have herein shown the baliiing" sections as having the same length and pitch of bladesections as is given to the screw sections 19, I do not Wish to be understood its n some forms'of pump it becomes necessary to increase the length of the blade sections to efliciently correct or quiet the swirling of the Water as delivered from the various sections 19.
Having thus describedmy invention, what I I'cla'im as new and desire to secure by Letters Patent is 1. A pump, comprising a driving shaft; a screw propeller section fixedly mounted on said shaft; and a rotatable baiing section Y loosely mounted on said shaft.
4 screw bladed propeller l'ixedly mounted on 2. A pump, comprising a driving shaft; a.
v'said shaft; and a rotatable baffling section loosely mounted on said shaft 'on the delivery side of said propeller, said bathing section having deiiecting sections pitched at an angle opposed to the angle of pitch of Ysaid propeller blades.
3. A pump, comprising a driving shaft; a
series of separated propeller sections having spiral anges extended therefrom, said sections being separated and l'ixedly .mounted on said shaft; and 'a plurality of rotatable baliiing sections interposed between said propeller sections and loosely mounted on said shaft, said baliiing sections .having deflectwl ing extensions radially disposed and pitched "toanangle opposed to the pitch "of the blades of said'-propeller sections..
4. A pump, comprisin a driving shaft; a' series of rotary ropel er sections fixedly mounted on said s aft; anda series of rotatable bathing sections loosely mounted on said shaft and adapted to be rotatedv by Water delivered from said propeller sections. l 5. A pump, comprising a. driving shaft; a series of propeller sections ixedly mounted on said shaft and having spiral propeller blades formed thereon; and a 4series of rotatable battling sections vinterposed between each of said propeller sections, said baflling sections being loosely mounted on said shaft and having spiral propeller blades formed thereon equal in-pitch to the propeller blades on said propeller sections, the pitch of said propeller blades on said batlling sections being reversed from those on the said propeller sections.
6. A pump, comprising a driving shaft; a cylindrical pump casing having inlet and delivery ends and bearings for said shaft; a plurality of screw propeller sections ixedly mounted on said shaft and in separated relation; and a plurality of rotatable baffling sections loosely mounted on said shaft, one of said sections being disposed on the delivery side of each of said propeller sections.
7. A. pump, comprising a driving shaft; a pump casing :for said shaft; a screw propeller section fixedly mounted on said shaft; and a rotatable spiral bladed propelled lsection loosely mounted Within `said .casing and on said shaft, the pitch of said spiral bladebeing set to defiect the Water as delivered from said propeller section toward a path parallel with said shaft.
8. A pump, comprising a cylindrical .casing; a driving shaft mounted centrally in said casing; a rotary. propeller. mounted to move with said shaft and adapted to gyrate the -Water as delivered therefrom; and a battling section provided with extended blades inclined at 'an' angle opposed to the gyration of the Water as delivered from said propeller, said bathing section being loosely Washington, I).
