ARTHUR E. SCHRAM, 0F ST. PAUL, MINNESOTA.
AIR-CLEANING DEVICE.
Application led April 21, 1920.'
To all whom it may concern.' V
Be it known that I, ARTHUR E. SCHRAM, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Air-Cleaning Devices, of which the following is a specification.
This invention relates t-oair cleaning devices for internal combustion engines and more vparticularly to that typewherein Water is employed for intercepting-the dust particles.
The invention is especially useful on tractors and is designed for separating the sand`and finer dust particles from the air before it enters the mouth lof the air intake of the carburetor.
The present invention is an improvement upon the air cleaner for which I have tiled. an application for Let-ters Patent on February 16th, 1920, Ser. No. 358,878 and is now pending.
An objec of the present invention `is to provide iml roved means for intermingling water and air to wash the latter by mechanical means set in motion by the suction in the intake of the carburetor set up bythe engine o A further object of the invention is to provide in a device of the class described 1mproved means for maintaining a. constant water level, said means including a. water' supply reservoir forming part of the device, the reservoir consisting of an ordinary fruit jar or the like, which can readily be replaced from any nearby household incase of accident. This is an important improvenient in devices of this kind aS there is-more or less waste due to evaporation andother causes, and because it is desirable at times to remove some ofthe sand accumulated at the bottom of the Water bath, the Water in the jar then serving as an immediate'supply to replace the Water lost in so doing. This is very important when on the field on a dry windy day.v
Another object of the invention is to provide' in "a device of the class described a Water gauge-So positioned as to iender visible from outside the moving parts within the enclosed tank forming part of the device.
A still furtherobj ect of the invention is to provide aself washing rotary water lifting Specification of Letters Patent.

are in close and open communication with,
said device so as to mingle with the supply of Water mechanically shaken from said device in its operation.
' To this endthe invention consists in the construction, combination and arrangement of parts hereinafter described and claimed:
Figure l is a. vertical sectional side view showing the general contour of the casing.
Figure 2 is a` perspective view of the cover of the casing showing it in inverted position.
Figure 3 is an end elevation of Figure l," a part thereof being shown in section on line 3 3 of Figure l.
Figurel 4 is a fragmentary sectional view of two of the baffle plates within the casing.
Figure 5 is a side view of the top of the water supply jar showing the method of holding the same positioned on the casing. the ar being shown in section.
Figure 6 is a fragmentary sectional view Figure 7 is a sectional view of a part of the reel, and f y Figure 8 is a diagrammatic side kview of a portiony of `an automobile showing applicants water supply positioned adjacent the dash board so as to be accessible and visible from the seat of the operator of the car.
In Figurel A represents .an elongated casing or tank and B the cover therefor, and
C vdesignates a water supply reservoir removably secured on the top of the cover B. The tank A is formed with' parallel The end walls as shown are also parallel to each other for a distance approximately half the depth of said tank and then slant inwardly to the bottom 3 of the tank so as to materially reduce the length of the latter, a drain plug 4 having screw threaded engagement with said bottom said plug serving as .an outlet to remove' the sand and grit accumulated within the tank. As shown in Figure l the level of thewater carried in the tank is located approximately at the bend of the end walls 2 so as to form a comparatively long Water surface lengthwise of the tank. At a point above the bottom 3 of the tank and at said water level is the transverse horizontally disposed shaft 5, the latter being mounted at its respective ends in the auxiliary side walls 6 secured on the undersurface of the cover B and extending downwardly into said tank a distance beyond said shaft and being parallel with the walls 1 and in close proximity thereto so as to form a comparatively narrow space 7 between them. The walls 6 are considerably shorter than the walls 1 so as to form at one end of.the interior tank an intake chamber 8 a cross wall 9 connecting them for this purpose. Between the cover and the water level and joining the side walls 6 is the horizontal partition wall or floor 10` said floor being formed with a curved portion 10 directly over the shaft 5 so as to form a circular undersurface concentric with the center of said shaft, the height of said floor from the water level being such as 'to form a comparatively wide elongated corridor air passage way 11 in open communication with the intake chamber 8, the latter being in open communication with the intake pipe 12 cutting through the cover and extending upwardly therefrom. The space above said floor is somewhat higher than the corridor 11 and forms a second corridor having an outlet 13 communicating with the pipe 11 leading to the intake of the carburetor not shown. Thus, the air is drawn in through the air intake pipe 12 through the chamber 8, the corridor 11 over the shaft 5, thence throuoh the secondary corridor 15 and .out of the pipe 14 into the carburetor. For the purpose of intercepting the air in its passage through the secondary corridor battle ` plates 16 and 17 are provided, the former being somewhat higher than the latter to` conform to the line of flow of the air and both extending upwardly and rearwardly for the purpose of having their undersur- ,faces at right angles to the flow of air. The
The top rail ot the frames of the reel move during rotation in close proximity to the curved portion 10 so as to form a comparatively air tight joint thercat. Thus, when the device is connected to the carburetor of an engine the suction set up in the passageways from the cylinders (not shown) will suck the air into the intake pipe 12, the suction being sufficiently strong to cause the reel to rotate thereby successively blocking the passage way 11 with one of its screened wings. As the water adheres to the screen by capillary attraction the passage way is virtuallyblocked by a film of water raised by mechanical means, the water being sucked from the screen to form a spray throughout the passage ways 11 and 15, the air mingling therewith land the free dirt particles being caught by the spray and deposited in the bath below. As the spray and air proceeds along its course the baffle plates 16, 1T and 19 serve as obstructions to break up the straight course of the advancing air curthereof and drain back into the tank as hereinbefore described.
Spanning the width of the tank and located approximately on the level of the shaft :Bor in other words at normal water level is the splash wall 24, the latter extending within a short distance of the reel at one end and the end wall of the casing at the other. When the tank is abruptly tilted, as is the case when the tractor is operating on uneven ground, the volume of water is prevented from splashing against the floor 10 which would result in the blocking of the passage way 11, the water finding its way into the latter, flowing back over the ends of the splash plate into the reservoir below. The plate 24 also functions as a dash plate to receive the dust particles thrown off at a tangent from the reel as is clearly indicated in dotted lines in Figure 1 of the drawings. The reel sometimes rotates in excess of 50 or 60 revolutions per minute the water being thereby thrown off at a tangent with consi'derable force causing it to dash against the top of the plate and carrying with it grit and sand. which latter is washed across the plate by the force of the stream to the opening 25, from whence it enters the tank below by means of the slanting portion of the end wall 2. The rapid rotation of the yreel causes the water to surge over the plate keeping a constant'stream owing thereover. Thus, the dirt collected is carried to the bottom of the tank as shown by the arrows at a point farthest removed from the reel so as to insure comparatively clear water 1n the zone in which the reel operates which facilitates washing of the` frames thereof.
By locating the reel lnearer one end of the tank, a long space is provided in the passage 11, between the reel and the wall 2, whereby the grit and other matter is caused to hit the surface of the water or the plate 24, before it can strike the wall 2, as is the case in my pending application, wherein the grit strikes the wall 1 and bounds against the screen G. In the present invention I position the suction opening 14 as far as possible from the discharge 'end of the pasage 11', so that any'free matter that might nd its way past the battle plate 19, will be dissipated in its long travel to the suction opening.
Firmly secured in the cover B and extending downwardly through the plate 24 is the tube 26. Arranged oneon either side of the tube 26 and firmly secured in the cover B are the rods 27 having threaded engagement at their outer free ends with thumb nuts 28, a cross bar 29 suitably drilled to loosely receive said rods being positioned so as to rest on the container 30, the latter being shown in the form of an ordinary fruit jar. As indicated in Figure 1 the jar has the usual threaded cover 31 fitting the threads of the neck 32 ofthe jar, a suitable gasket 33 forming an air tight joint in the usual manner. The cover has a central aperture 34 adapted to loosely receive the upper end of the tube 26, a gasket 35 being interposed between the covers 31 and B so as to form an air tight joint between them. Thus, the Water inthe jar mingles with the water in the tank below, the mouth of the tube extending a slight distance below the Water level. Obviously, when the water level becomes lowered belowthe mouth of the tube 26 air will enter the latter and permit the watei1 from the jar to descend into the r'eser voir until the tube is again sealed. Thus, the water level in the tank is automatically maintained. A water inlet 36 pie-rcing the cover B and having a screw cap 37 to form an air tight closure for said inlet is provided for replenishing the tank or for flushing the same.
By having the discharge opening 26 of the barometric water supply positioned on the discharge side of the reel in the region of the plate 24, the fresh clean water enters at a point near the wingsas they successively enter the water heaviest laden-with grit, and at whichy point the water in the tank becomes normally thickly charged with sand and other matter.
In order to render the interior above the water'level on the suction side of the tank comparatively -air tight so that a maximum suction action may be obtained for actuating the reel a felt strip 3S held positioned on the side wall as by means of the spring clip 39 is provided. A feature of construction in the present invention resides in the mounting of the reel support together with the intermediate wall effecting the two superposed air passage ways, on the underside of the cover so as to be movable therewith. By simply removing the cover the device is accessible for cleansing purposes orrepairs, this construction also facilitat-ing the manufacture thereof. Arranged in one of the sides 1 of the tank and Jositioned so as to render visible a part o the reel both above and below the water line is the gauge glass 40 whereby the condition of the operating parts may be readily ascertained without disassembling the entire device. In Figure 8 applicants device is shown as applied to an automobile, the water suppl)7 reservoir C being located at the dash board of the machine so as to be visible by the operator thereof. lVhen the water in the reservoir falls below a given level the valve 41 is closed to prevent air entering the tank and the reservoir may then be refilled.
