Specification of Letters Patent.

llpplicatiou filed July 19.1907. Serigltllo. 384596.

T 0 all whom it may concern:

Be it known that l, ALBERT W. Ovnnmenu, a citizen oithe United States, residing in the township of Casco, county of Allegan, State of Michigan, have invented cer- 'tain new and useful Improvements in Screen provide an improved straining or screening device for use on spray pumps and the like by which the clogging of the suction pipe of the nu ip is prevented, and also a screening device which is automatically cleaned or freed from sediment by the operation of the pump.

Further objects and objects relating'to de tails of construction Will definitely appear from the detailed description to follow.

l accon'iplish the objects of my invention by the devices and means described in the following speci'ication.

The invention isclearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

Figure 1 is a conventional view of a pump showing the relation of my improved screening device thereto; Fig. 2 is a side elevation of a structure em bodying the features of my invcnti on; Fi 3 is an end elevation thereof; l' irg". lis a detail longitudinal section theretlirough taken on a line corresponding to line 3-3 of Fig and is enlarged detail taken on a line corresponding: to line 4-4 of Fig. 3, showing the supporting legs of the strai In tlie drawings similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to thedrewing? 3. represents a pump, the same being shown in conventional form. This pump is of the type having a suction pipe as 2 and a return pipe as 3, the return pipe being designed to deliver into the tank containing the sprsyingsolution, there by keeping the solution properly agitated.

My improved screening or spraying device preferably consists of a block 4 having pipe openings 5 and 6 tberetbrough adapted to receive the ends of the suction and return pipes respectively. The block 4 is supported on suitable legs as 7, these legs being preferably formed of Wire bentinto loop form, as illustrated in Fig. 3, theendsof the Wire being inserted into the blocks for securing the legs thereto. See Fig. 5. On the under side of the block I secure a screen 8 forming a screening or straining chamber. This screen is preferably formed of a iece of Wire net or screen folded to form a c amber, the block a forming the top thereof. The screen is secured to the block preferably byrneans of a band 9 Wrapped about the same and secured to the block by means of nails'or brads 10. This construction, is a very economical. one and at the same time is found to be entirely satisfactory in practice. The pipe 0 enings 5 and 6 are preferably arranged tl irough the block so that the return pipe 3 delivers at an angle across the mouth of the suction pipe and also at an angle across the bottom of the screening chamber. This prevents the collection of sediment at the mouth of the suction pipe, as at each stroke of the pump a portion of the charge is delivered baok'into the pump and also by deliv ring at an angle to the bottom of the screen chamber frees the same from obstructions. This arrangementalso insures the proper agitation of the spraying solution at the mouth of the suction tube.

It will be obvious that my improved screening or straining device, is very simple in construction and at the same tinie it is highly effective for the purpose for which it is designed.

l have illustrated and. described the same in detail in the form preferred by me on account of its structural simplicity. I am, however, aware that it is capable of very great variation in structural details Without departing from rnviuvention, and I desire to be understood as claiming the same broadly as Well as specifically, as illustrated.

Having thus described my invention, What 25 v mouth of the suction pipe and stain angle to 40 tion and return pipe therefor; a strainer com- I claim as new and desire to secure by Letters Patent is:

1. The combination 'with a pump, ofa suction and return pipe therefor; a strainer comprising a block having a pair of pipe openings therethrough in which said suction and returnpipes are arranged supporting le s for said block, and a screen secured to said block to form, a screening chamber on the under side thereof, said pipe openings of said block being arranged at an angle to each other so that the said return pipe delivers into the screening chamber across the mouth of the suction pipe and at an angle to the bottom of the screening chamber.

2. The combination with a-pump, ofa suction and return pipe therefor; a 'strainercornprising a block having a pair of pipe openings therethrough in which said suction and re turn pipes are arranged; and a screen secured to said block to form a screening chamher on the under side thercof,;said pipe openings of said block bein arranged at an an 1e to each other so that t c said return pipe elivcrs into the screening chamber across the p the bottom of the screening chamber.

3. Thecombination with apump of a suction and return pipe therefor; a strainer comprisinfibiock having a pair of pipe openings theret ough in which saidisuction and return-"pi es are arranged supporting is s for said block, and a screen secured to said loch to form a screening chamber on the-under side thereof, said pipe openings of said block being arranged at an angle to each otherso that the said return pipe delivers into the screening chamber across the mouth of the suction pipe.

4. The combination With a pump, of a sucprisin a block having a pair of pi openings ther'et rough in which said suctiiin and return pipes are arranged;'and a screen secured to said block to forma screening chamher on the under side thereof, said pipe openings of said block bein arranged at an, angle to each other so that t e said return pipe delivers into the screening chamber across the mouth of the suction pipe.

5.. The combination with a pump, ofa suction and return pipe therefor; a strainer comprisin a block having a pair of pipe openings theret rough in which the said suction and return pipes are arranged; supporting le S for said block, and a screen secured to said lock to form a screening chamber 6. The combination with a pump, of a sue tion'and return pipe therefor; a strainer coma block having a pair of pipe openings" tion and a return pipe there or a screening.

chamber towhich said suction and return pipes are connected, so that the said return pipe delivers into the screening chamber across the mouth of the'suction pipe,

9. The combination with a pumpof a suction and return pipe therefor; a strainer to which said suction and'return pipe are connected, comprising a screen, said return pipebeing arranged to deliver to said screen at an an 10 thereto.

nwitness whereof, I have hereunto set my 85 hand and seal in the presence of .two wit nesses.
