July 17, 1951 M. E. OSBURN BAFFLE FOR DRAINAGE PORTS File d March 14, 1947 llllllllllili r m m W r U 0 S 0 E Patented July 17, 1951 UNITED, STAT Es PATENT OFFICE 1 Claim.

The present invention relates to a novel baffle attachment for a pump pipe and has more particular reference to a deflector-type baflie for a stream of water issuing from a drainage port in the pump pipe.

In water supply wells wherein a hand or equivalent pump is situated above the ground and exposed to freezing weather conditions it is common practice to provide a drainage port or opening in the delivery pipe below the so-called frost line, whereby to permit all water which has been trapped above the port to be drained into the well and to thus prevent the pump from freezing. It is a matter of common knowledge, however, that the jet or stream of water often plays upon the well casing and, in due season, the focal spot fractures or breaks through. Consequently, the jet of water then plays upon the earth surrounding the casing, permitting undesirable mud and extraneous matter to return to the well by way of the fracture.

It is the purpose of the present invention to overcome the aforementioned objection and to protect the well casing and to promote greater operational efficiency of the well and. pump.

Another object of the invention is to intercept the issuing drainage stream and to deflect same downwardly into the well.

More specifically, the invention has to do with a simple and economical attachment such as may be readily installed and which achieves the desired end as effectively as more complicated devices which have been heretofore offered by others to attain somewhat the same results.

Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a fragmentary elevational and sectional View showing a portion of the well casing, the pump pipe, the pump, and the improved baffle attachment mounted on the pipe adjacent the drainage port.

Figure 2 is an enlarged fragmentary perspective View detailing the construction and mode of attachment of said baffle.

Figure 3 is an elevational view of the main bafiie equipped part of the attachment.

Figure 4 is an edge elevation view at right angles to Figure 2 showing the construction and relationship, the pipe being in dotted lines.

Figure 5 is a perspective view showing the complemental part which goes to make up the complete attachment.

Referring to Figure l the reference character A designates the ground, B denotes the pump or well pipe, C the casing and D the pump above the ground. The drainage port or hole in the pipe B is denoted by the reference character E. This is a common feature as before implied. Its purpose is to drain back water from the pump and portion of the pipe in order that it may escape into the well and empty that part of the pipe and pump above the opening, whereby to prevent the pump from freezing. The object of the present invention, as before stated, is to intercept the issuing jet or stream of Water and to deflect it downwardly and this is accomplished through the medium of a simple and economical two-part attachment. This attachment comprises a baiiie plate I depending from and attached to the semicircular portion 3 of a sectional clamping and retaining band. The end portions 9 of the band are notched or otherwise formed to cooperate with correspondingly notched or bifurcated end portions It on the remaining semi-circular clamping band I I. The end portions 9 and it are brought together to accommodate bolt and nut retaining means it, this as shown in Figures 1 and 2. The bafiie plate is of a dished formation as shown in Figure 4 and functions not only as a deflector but as an anti-splash apron. It is laterally ofiset in respect to the adjacent surface of the pipe B as illustrated in Figure 4 and, being thus faced and set, it accomplishes the desired ends with requisite appropriateness and fitness.

Summing up the invention, it is a simple and practical attachment, is characterized primarily by an attaching band of flexible construction embracing the pipe at the desired elevation and carrying and positioning the baffie plate where needed. It follows, therefore, that the invention being of such self evident simplicity, a more elaborate description thereof is presumably unnecessary. What is more, the advantages and resultfulness of accomplishments will be full well understood and aptly appreciated by those skilled in the art to which the invention relates.

Changes in shape, size, materials and rearrangement of details and parts may be resorted to in actual practice, so long as they do not depart from the spirit of the invention or the scope of the appended claim, as is well understood.

What is claimed as new is:

Pump protecting baffie means for use with a pump structure embodying a Well casing, a water delivery and pump attaching pipe mounted in the casing, a pump secured to the upper discharge end of the pipe, said pipe having a drain- 3 age hole therein at a predetermined level and within the confines of the surrounding casing, said baflie means comprising, a pair of semicircular attaching bands embracing the pipe at a point above the drainage hole, a concaveconvex baffle plate connected at one end to one of said bands and being offset therefrom, said plate extending downwardly from said band in spaced parallelism With:the draina e rholeand being bent inwardly at the lower end thereof toward the pipe to assure the passage of the water in a direction toward said pipe and away from said casing, the ends of said-bands-being bifurcated and laterally bent and abutting one another, and bolt and nut retaining means con 15 REFERENCES CITED The following references are of record in the file of this patent:
