Filed Dec. 28, 1928 '2 Sheets-Sheet 1929- J. MARKMAN 1,734,440 I bRAINAGE PUMP Filed Dec. 28, 192B 2 Sheets-Sheet 2 Patented Nov. 5, 1929 JOHN MARKMAN, OF FORRESTON, ILLINOIS PATENT OFFICE DRAINAGE PUMP 'Appl icat ion filed December 28, 1528. Serial No. 329,019.
My invention relates particularly to drainage (pumps such as are employed for conveying the water from low land and discharging the same into a river or the like,it being understood however that the pump is capable of other uses too numerous to mention.
The invention has for its primary object to provide a very simple and eiiicient device of the class describedwhich will move great volumes of fluid or semi-fluid with a minimum expenditure of poWer,-the nature of the construction being such as to render it capable of being readily assembled and disassembled.
, The invention also resides in certain novel features of construction, combination and arrangement of the various parts all of which willbe fully set forth in the accompanying description, or will readily suggest themselves to those skilled in the art uponreterencetothe accompanying drawings forming a part of this'specification.
WVhile the preferred embodiment of the invention hasbeen illustrated in the drawings, yet it will be understood that the same is susceptible of considerable change and modification Within the spirit and scope oi the subject matter-claimed hereinafter.
In the drawings, wherein the same reference characters have been used to designate the same parts in all views, j
t Figure 1 is a vertical sectional view; through a dike or the like and showing, combined therewith, a pump installation incorporating my invention T i Figure'Q is a cross sectional viewtaken on the line22 of Figure 2; ,j I "Figure 3 is a section onthe line 38 of Figure 1;
Figure 4 is an enlarged detailed sectional view showing the joint connection between the c c slide in the guide, which 1s to say under and pump unit and the tank or housing p j iguiie 5 is a group perspective view of the wall and tank assembling guide portions. Referring specifically to the drawings, numeral 1 denotes a dike or wall of cement located at the river bank and which wall will, of course, have footing considerably below the'river bed. 'The Wall may be interposed at a convenient point in a dirt dike or levee where it is desired that lowland water be emptied into the river.
The wall 1 has an opening 2 which is preferably located well below the surface of the river and adjacent low land so that all the drainage water from the lowland may drain to the opening 2 in the wall.
The wall opening 2 is provided with a cylindrical casing 3, which is suitably sealed in said opening. The casing 3 projects through the wall 1 into the river and has its projecting end cut on a bias, as shown, to provide a valve seat 3 for the flap valve 4, which is hinged to the casing 3; as indicated at P. The valve4 will, of course,be open when thepump is in operation to discharge fluid into the river past the valve. The valve 4 is controlled by a rod 5 leading to the top of the wall 1 and which is pivoted to the valve, as indicated at 5 L 1 p p The other, end of the casing 2 is suitably flanged, as at 2 for connection as at 2 to the flange Bof a valve casing B which extends through a hole 6 in tank 6.
The tank 6 is preferably cylindrical in form and is of a height to extend substantially to the top of the dike. The bottom of the tank 6 isembedded in the ground at a depth approximately equal to the depth of the footing of the cement wall 1. In any event, the tank must be low enough so that the water from the lowermost drainage ditch of the drainage area will drain thereinto as will be described more specifically later on. I
The wall lis provided with one or more. 85 vertically disposed guide-Ways 7 which comprise opposed,ofi:-set flanges of heavy iron bolted to the wall 1, as indicated at 8. The
provide a valve seat 17 for a flap valve 13 which is pivoted, as at 19,110 said valve cas-.
ing. It will be understood that the valve casing 15 extends into a well or a hole located at the lowermost pointlof the drainage area.
' -Thus, all the water willflow into the valve casing 15 and then into the passage l l, when the valve 18 is open. The valve 18 is controlled by a rod20 which canbe operated from the top of the tank 6.
The passage 14 is off-set, as shown. and is separatedfrom themotor chamber 11. which is closed except fora rear end closure plate 10*.
The flanges 11,'12,terminate short of the end of the casing 10 adjacent the gate valve casing B. Atthis end the casinglO is cire cular and contains only conduit 14. To effeet a connection between-the main casing 10 and gate valve casing B. I provide a collar C having lateral inturned circumferential flange C at the innerend and an outwardly and rearwardly flared circumferential flange C" at its other end. FlangeC' bears against the circumferential end of casing 10 beyond the ends of side flanges 11 12 of the sections ll, 12 which form casing 10. This end of casing 10 has a lateral flange formed by the semi-circular end'flan 'es D of sections Z I 11 12. Between flan es D C 1s a com- 7 n 7 pressible gasket E. Flange C of collar C fits into the matmg flange B" ofgate valve casing Band the two are secured togetherv by bolts F Obviouslygasket E seals the joint between C and 10, and since C slides on 10 the latter with C can beremovedfrom tank 6 without disturbing the attachment of. gate valve casing B to flap valve cas ng As showmthe twosections 11, 12 ofmain casing 10 are boltedtogether on a line parallel with the axis of the impeller shaft 22 which extendsinto the offset discharge end of the passage 1% and carries the impeller, 23 disposed therein. The packing gland 2 1 through which shaft 22 extends, is halved, one-half being carried by the section 11 and the other half by the section 12. Within the compartment 14: is a thrust bearing, the fixed portion of which is defined by the sections 11, 12 of the respective casing sections. The shaft 22 is provided with a number of spaced shoulders 40 suitably engaging with the partitions 41 of the thrustbeari'ng sections so as to take up the end thrust of'the shaft 22 induced by the flow of water through the passage 14, (see Figure 1).
Of course, the rear end of the motor compartment 1 1' will be closed. as shown. The impeller shaft 22extends through the thrust bearing housing 11, 12 and has connection with the armature shaft 25 of the motor 26 through the flexible coupling 27 which may be of any preferred or conventional design.
It is desired to point out at this stage of,
the description that the. gate valve. casing B,
previously mentioned, has a gateva-lve 28L whichis operated'by a control handle 29, as indicated. This gate valve 28 willbe closed when the pump is being repaired.
The top of the tank 6 is provided with a doorway 30 and also with windows 31. Within the tank 6 there is a spiral'stairway 32', which is accessible from the doorway 30. The stairway leads to the bottom of the tank and gives ready. access to the pump unit-for purposes of inspection, installation or repair.
The top. or closure 33 of'the tank may be bolted to a supporting flange 36,; as at 35. Also the closure 33 may have a central ring 37 for attachment of hoisting tackle for raising orlowering the tank.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In a device ofthe class described, a wall, a tank, and guide means associated with the wall and tank whereby the latter can be slid into place and maintained in close proximity to the wall, anda pump unit in said'tank having an inlet through one side thereof and an outlet through the other, the wall having an openingv adapted to register, with said pump outlet of the tank.
