Specification of .Letters Patent.
Patented May 26, 1914.
Be it known thatl'I, ELMER E. HAUER, a
' citizen 'Qf -the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Strainers for Pumps, of which the following isaspecification, reference being-had therein tothe accompanying drawings.
My invention relatesto strainers and -more particularly to aist'rainer for pumps.
The object of my invention is to provide an improved strainer having a straining and cleaning chamber' with a movable strainer element therein adapted to carry and discharge the refuse caught by it through an opening into a discharge chamber, means also being provided to gather and discharge in like manner any of the refuse that adheres to the strainer element; said discharge chamber having anormally closed outlet and means to close the communication with said straining and cleaning chamber when said'normally closed outlet is open.
With these and other objects in view my invention consists of the constructions and combinations hereinafter described and set forth in the claims.
In the drawings Figure 1 is a vertical section of a strainer embodying my invention. Fig. 2 is a like section taken on the line 22 of Fig. 1. Fig. 3 is a section taken on the line 3-3 of Fig. 2 and Fig. 4 isa section taken on the line 4=4 of Fig, 1.
Like numerals representthe same parts in the several views.
. In the drawings 1 represents a casing having a head 2 preferably cast integral therenections form the lower part of the straining and cleaning chamber and also a discharge chamber 9 with an opening 10 between said chambers in which a hollow valve 11' to control said opening is seated. Said valve is provided with openings or ports 12 and an enlarged portion 1'3 of the casing extension forms a stop and bearing for the inner end of the valve, which is introduced through the open end and is held in place by a cap 14 secured to the casing extension and provided' with a stufling box as shown. A handle. 15 is provided to operate the valve.
A rotary strainer element having circumferential longitudinally extending perforated walls is provided within the straining and cleaning chamber, the preferred form of which is shown as comprising wheels at the respective ends of said chamber having hubs 16 mounted upon a shaft 17 journaled at one end in the head 2 and at the other end in an arm 7 projecting from the,outlet 7; said wheels having spokes 18 and rims 18 with segmental webs -19. Longitudinally extending perforated plates 20 form depressions, troughs or pockets secured at their respective ends to said webs by rivets as shown, or in any suitable way.
A cleaner element which is shown in the form of a paddle or scraper 21 fixed upon,
a shaft 22 journaled' in opposite ends of the casing and extending through one end thereof is provided with a handle 23 to operate the same.
A- head 24 provided with handles 24 swings upon a hinge 25 secured to the casing extension and is normally held closed by bolts 26. Said head is provided with an annular groove or recess in which a packing 27 is secured to insure a tight joint when said head is closed. v.
When the strainer is employed in a suction line and the valve 11 is closed and the discharge chamber 9 is open for cleaning, it is essential that no air be admitted to the line and to prevent leakage through the valve a water-seal is provided, water being introduced to the valve for this purpose through a pipe 28 connected to any suitable source of supply. i
The rotary strainer element may be manually operated or driven by. power, both means-being shown in the drawings. The power driving means .is shown in the form of a motor having a casing'29 secured to the head 6 and a wheel 30 with buckets 31 is supplied with the motive element through a nozzle 32 connected to any suitable source of supply. Said wheel is fixed upon a shaft 33 journaled in the head 6 and casing 29 and a pinion 34 fixed on said shaft is adapted to mesh with cogs 35 on the rim of one of the strainer element wheels. A hand-screw 36 in the casing 29 can be tightened against the wheel to lessen the speed of the wheel if desired.
The means to manually operate the strainer element are shown in the form of a hand-wheel 37 fixed upon a shaft 38 journaled in the casing extension and provided with a stufiing box as shown to prevent leakage, said shaft having a pinion 39 fixed thereon and adapted to mesh with the cogs of the rim of one of the strainer elementwheels. A stop 40 operated-in a holder 41 secured to the enlarged portion 13 of the casing extension, is pressed against the shaft 38 by a spring 42 and engages a recess in said shaft at each revolution thereof. The pinion 39 is of such diameter that at each revolution thereof, each trough or pocket 'of the strainer element will be stopped in proper relation to the cleaner element 21 for the operation of said cleaner. A pin 43 fixed to the stop and adapted to pass through a slot 4:4: in the stop-holder is provided. By taking hold of the handle 45 the stop can be pulled and turned so that the-pin will engage the outer end of the stop-holder and hold the stop out of engagement with the and cleaning chamber so that sticks or like material caught and carried by the troughs or pockets of the strainer element will, by the movement of said element past said knife edge, be cut into pieces of such size as will pass in said troughs or pockets to 'the discharge chamber.
The strainer element shows six of the perforated troughs or pockets with two of them in operative relation to the inlet; but it is obvious that the proportions may be changed and a greater or less number of the troughs or pockets employed. The fluid passes through the perforated trough or troughs in operative relation toxthe inlet to the inte rior of the strainer element and thence through the outlet end thereof. The strainer element may be driven by power or manipulated by hand and the refuse caught by the troughs or pockets when in operative relation to the inlet is carried and dropped through the opening 10 to the discharge chamber; and any of the refuse adhering to the troughs or pockets is gathered and dis charged by the cleaner element 21 through said opening into the discharge chamber.
When it is desired to remove the refuse from the discharge chamber the valve 11 is closed and the head 24 is open for this purpose.
Having thus described my invention I claim 1. In a strainer, a casing having a chamber with an inlet and outlet adapted to be connected :n a pipe line, a rotary strainer tive and a portion into inoperative relation to said inlet, means to rotate and a stop to hold said strainer element from rotation and means secured to said casing and operative within said chamber to clean the portion of same not in operative position.
3. In a strainer, a casing having a straining and cleaning chamber with an inlet and outlet and a discharge chamber with a normally closed outlet, a rotary strainer element having longitudinally extending perforated outer walls, the rotation of which brings a portion thereof into operative and a portion into inoperative relation to said inlet, means to cleanthe portion in inoperative position and a valve between said straining and cleaning chamber and said discharge chamber to prevent the escape of fluid when said normally closed outlet is open.
4; In a strainer, a casing having a straining and cleaning chamber with an inlet and outlet and a discharge chamber with a nor mally closed outlet, a rotary strainer element and a cleaner element operative between said strainer element and the outlet of the straining and cleaning chamber to gather and discharge the refuse caught by said strainer element through an opening into said discharge chamber and means to close said opening when said normally closed outlet is open.
