PUMP.

pasarse.

To all whom t may concern: i Be it known that I, WAYNE W. BLAoK- BURN, a citizen of the United States, residing at St. Petersburg, in the county of Pinellas and State of Florida, have invented certain new and useful Improvements in Pumps, 0f which the following is a specification.

My invention relates to pumps and more particularly to that type wherein a turbine is employed preferably for dredging purposes. l The primary object of my invention resides in the provision of an improved means associated with the blades of the fan or turbine for causing the liquid that is being pumped to pass directly through the fan during the operation thereof thus increasing the efficiency of the pump, said means also serving another purpose, that of preventing the throwing of the water laterally from the blades as well as incidentally serving the purpose of increasing the eciency of the joint between the sections of the pump cylinder.

A. further object of my invention resides in the provision of a device of the character described that is simple in construction, efficient in operation and one that can be manufactured and placed on the market at a minimum cost.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claim forming a part of this specification.

ln the drawing Figue l is a side elevational view of my invention Fig. 2 is a longitudinal central sectional view of the pump cylinder showing the fan positioned therein; and

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2 in the direction in which the arrow points.

Referring more particularly to the drawings in which similar reference numerals designate like or corresponding parts throughout the different views, I provide a pump cylinder formed preferably of two conical shaped sections l and 2, said sections having flanges 3 projecting from their enlarged ends for faciliating the connection of the sections through the medium of fasten- Specification of Letters Patent.

and inlet being faciliated through the medium of a collar 6. The inlet is controlled through the medium of a check valve 7 associated therewith. The section 2 is provided with an opening 8 having a col lar 9 formed thereabout, the latter receiving an outlet pipe 10, preferably in screwthreaded engagement with the coil.

In order to support the inlet and consequently the pump cylinder, I have provided standards 1l and 12, the standard 1l having an opening therethrough for supporting a portion of the inlet 5 as illustrated to advantage in the drawing. The opposite end of the cylinder or section 2 has its apex rigidly supported in the combination bearing and stuffing box. provided in the upper end of the standard 12 and includes preferably an inwardly eX- tending recess 13 having packing material 14 therein, the bottom of the recess having an opening 15 formed therein. f

ln order to create a vacuum within the cylinder and consequently draw liquids thereinto through the inlet and force them through the outlet, preparatory to the securing of the sections l and 2 of the cylinder together, I have rotatably` mounted in the opening l5 and in the apex of the section 2, a shaft 16, the inner end of which terminates approximately in a plane in alinement with the joint formed at the base of the sections 1 and 2, and which shaft has rigidly mounted thereon my improved fan or turbine 17. In this instance the fan includes a collar having a plurality of blades 18 proj ecting radially therefrom, the terminals of This arrangement is` the blades having secured thereto a ring or shroud 19, formed preferably of brass, through the medium of suitable securing elements 20. This ring incidentally forms the essential part of this invention and is arranged in close relation with the point of juncture of the sections l and r2. By this arrangement it is readily apparent that the water or other liquid being drawn through the cylinder will be consequently forced to pass through the propeller itself, thus increasing the efficiency of the operation of the arrangement. lt will also be noted that the water will not be thrown against the point of juncture of the sections and as a affected. l

In order to rotate the fan and consequently create a suction within the cylinder which naturally draws liquid into the inlet and forces it through the outlet, I have mounted a gear 21 on the free projecting end thereof, said gear being in mesh with a smaller gear 22 carried on the rotating shaft 23 of a motor 24, 'the latter constituting a suitable source of power.

Although I have shown and described the preferred embodiment of my invention `I de sire to beunderstood that I am not to be limited to the eXact details shown, however, I desire that great stress be laid upon the arrangement of the means as associated with the fan for performing the dual purpose of increasing the eiiiciency of the fan as well as providing a means for protecting the joint betweenthe tWo sections of the cyiinder. These sections as is obvious can be detached when it is desired to clean the cylinder on the interior thereof. l/Vhen starting the pump it is rst necessary-to fill the same with water so that whenthe fan is rotated it will cause a suction throughthe inlet, which suction will incidentally draw the water into the cylinder through the inlet anddischarge it through the outlet.

From the above description taken in connection -with the accompanying drawings, it can easily be seen that I have provided a device that is simple infconstruction, containing but a few simpleparts that can be cheaply -manufactured and assembled and when vassembled can be placed upon the market and sold at a minimum cost.

@It will be understood that the abovefdescription and accompanying drawings conv prehend only the preferred embodiment of my invention and that various minor changes in detail of construction, proportion and arrangement of the parts may be made within the scope ofthe appended claim and without sacrificing any of the advantages of my invention.V

I-Iaving thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

A pump comprising in combination With spaced standards having openings therein, a cylindercoinposed of twoseparahle coni cal sections, each section being provided on its largest diameter with a flange extending outwardly therefrom and the smaller ends terminating` in cylindrical extensions-adapted to be received in the openings `in the standards, means passing through the flanges for securing the sections together, said cylinder being formed interiorly with a bearing surface at'thejuncture of the two sections, a rotatable shaft passing through the cylindrical eXtension'on one section and projecting into the cylinder, an impeller mounted upon the inner end of the shaft, said impeller being provided circumferentiaily with a shroud adapted to rotate inthe bearing surface formed at the-juncture of the sections and thus serve tofsupport the shaft at the impeller end, means for rotating the shaft and therefrom 'the impeller, and inlet and out ports.

In testimony whereof I aixmy signature in presence of two witnesses.
