' No. 549,390. Patgnted Nov. 5,1895.






SPECIFICATION forming part of Letters Patent No. 549,390, dated November 5, 1895.

Application filed December 24, 1894. Serial No'.632,828- (N 0 model.)

.To all whom it may concern:

Be it known that we, JAMES PATTERSON, of Williamstown, in the county of lVood and State of Vest Virginia, and MicHAEL B. CAR- MODY, of Marietta, in the county of \Vash,

struction, very effective in operation, ar ranged to intercept solid matter and other impurities,'and to permit of conveniently re;

moving quired.

The invention consists principally of a the same from time to time, as rescreen arranged in the path of the fluid and at an angle to its flow. v

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawing, forming a partof this specification, in which the figure is a sectional -sidc clcvat-ion of the improvement.

The improved screening device is provided with a casing A, of cylindrical, splicrical, or other form, and through which flows the fluid in the direction of the arrow a, the said casing being arranged in a main pipe or other conductor B, as is illustrated in the drawing.

In the casing A is arranged a scrccn t, standing approximately at an angle of about fort "-five degrees to the tiow of the fluid pass- .ing through the casing, and this screen C is preferably supported on suitable transvcrsc bars VI) to hold the scrccn in a comparatively straight position. The screen is introduced into tho casing A through an opening A, forlncd in the top of thccasiug i-\,-and on the upper cud of thc scrccn is sccurcd a transverse bar I extending into thc cnlargcd portion A of the opening A to rust on tho shoulders formed in the casing A. Thc outer end of the opening A is' adapted to be closed by a suitable cap F, bolted or otherwise fastened to the casing A, and when removed permits of withdrawingthe screen 0 from the casing for repairs, for replacing, or for other purposes, as'the case may be. On the bar E is formed a hook E for conveniently removing the screen whenever desired. The lower end of the screen 0 extends into a transverse slot A formed on the inside of the casing, as indicated in the drawing. The lower part of the screen 0 discharges into a recess A formed in the bottom of the casing A and provided with a draw-off cock G for removing or drawing otf the accumulated solid matter or impurities from time to time. At the top of the recess A is arranged a horizontallylisposed screen lI, secured in place by screws or other means and terminating at its free and slightly downwardly-curved end a suitable distance from the lower end of the screen 0 to form a passage I for the solid matter or other impurities intercepted by the screen C.

Now it will be seen that solid matter or other impurities contained in the liquid flowing through the casing are not capable of passing through the meshes of the screen, as they are intercepted by the latter and roll down the screen to pass through thepassage I into the recess A, in which they accumulate and are retained by the screen ll, to be drawn off from time to time.

Now it will be seen that by setting the screen at an angle to the flow of the fluid the solid matter is intercepted and discharged at the bottom, as described, and atthe same time a large scrccnirig-surface is presented to thc fluid. Furt hcrmore, the screen may be easily removed for, cleaning or other purposes.

llaving thus fully described our invent ion, we claim as new and desire to sccurcby l.cttors latcnt.

A scrccningdcvicc lor fluids, comprising a casing formed with an opening in the top havinganoutcrcnlargcd portion and ail-ansvcrsc rcccss formed in thc insidc of thc bottom of said casing, a scrccn hcld rcmovably in the casing and fitting at its lower end in the said transverse recess, and a transverse bar secured to the top of said screen and hold in the enlarged portion of the opening in the top of the casing, substantially as shown and described.

2. A screening device for fluids, comprising a casing formed'with an opening in its top having an outer enlarged portion, a screen held removably in the said casing, transverse bars arranged in said casing to support the said screen, a transverse bar secured to the upper end of the screen and adapted to rest in the enlarged portion of the opening and means for closing the outer end of the opening, substantially as described.

3. A screeningdevice for fluids, comprising a casing formed with a recess for receiving collected impurities and other matter, the said casing being provided with an opening in its top having an outer enlarged portion,

the inner surface of the casing at the bottom being provided with a transverse groove, a 2

screen held removably in the said casing and fitting with its lower end in the said transverse groove, the upper end of the screen being provided with a bar adapted to rest in the e11- larged portion of the opening, the said screen 2 the inclined screen to form a passage leading c into the said recess, substantially as shown and described.
