DUST-COLLECTOR FOR CARBURETERS.

Application filed July 2, 1917. Serial No. 178,120.

To all whom it may concern Be it known that 1, CHARLES H. ST NsoN, a citizen of the United States, residing at Superior, in the county of Douglas and State of'lVisconsin, have invented certain new and useful Improvements in Dust-Collectors for Carbureters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a simple and efficient device or attachment. for carbureters, whereby all dirt and dust I will be removed, from the air before it enter-s the carbureter on its way to the cylinders of an explosive engine,

It is a well .known fact that the dust and dirtcarried with the carbureted air into the cylinders of explosive engines, not only grinds and cuts the same, but works its way into the lubricating oil and thereby de creases the efficiency thereof and sometimes entirely destroys the lubricating action. This is especially so in the use of explosive engines on tractors which are necessarily used where dirt and dust in-great quantities will mix with the air taken into the car- In my experiencein the use of tractors driven by explosive engines,;I have frequently found that the dirt worked into the lubricating oil between the piston and cylinder, would accumulate until the entire body of the lubricating oil was turned into a pasty mass which would not lubricate at all. When this happens, the engine, of course, runs dry and rapidly cuts itself to pieces.

improved dust collector forcarbureters involves means for washing the air and thereby collecting the dust therefrom, before it is taken into the earbureter, but the invention also involves other important features of construction, as will hereinafter appear. a The invention is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views. Referring to the drawings, a

Figure 1 is a view partly in vertical section and partly in diagram; and

Fig. 2 is a horizontal section on theline 2-2 of Fig. 1. v

view while the carbureter is shown in ele-.

vation and the dust collector in vertical section, this being done for illustrative purposes, but it will, of course, be understood Of the parts of the engine, it is only desirable for the purposes of this case to particularly note the intake manifold 3, the' exhaust manifold 4:, the water jacket chamber 5 and cylinder casting 6. The carbureter, which is of the usual or any suit. able construction,.is indicated, as an entirety,

bv the numeral 7 and delivers to the intake nianifold Sin the customary way.

The dust collector is preferably made with an upright cylindrical body channel 8 having a contractedbottom section 9 with a drain passage normallyclosed by a plug 10. The upper portion of the channel 8 is formed with a surrounding chamber 11 that is connected by apipe 12 to the main exhaust pipe 13, which latter leads from the exhaust manifold. At that side opposite to the point of attachment to the exhaust of the branch exhaust pipe 12, the chamber 11 has an extended exhaust pipe 14. With this arrangement, part of the exhaust products of combustion will be forced through the chamberlland will thereby heat the upper portion of the channel 8, for the purpose of superheating the cleaned air taken into the carbureter.

The top of the channel 8 is connected to the carburetor 7 by an air intake pipe 15. Outside air is drawn into the shell 8 through an axial air intake tube 16 shown as rigidly secured to a detachable cover 8 of said shell. Here it may be noted that the lower end of air pipe 15 is, as shown, also directly attached'to said cover. The upper end of the air intake tube 16.is covered by a wire gauze 17 which will prevent large particles of dirt from entering the dust collector.

The dust collecting chamber formed within the shell 8 contains water y to a lever that is above the lower end of the air intake tube 16, so that all air drawn into the said shell will be passed throughthe water and washed, or, in other words, collected in the water. The level of the water in the said dust collecting chamber is preferably autovalve 21 isautomaticallf l lever that is intermediately pivoted'to the side walls of matically maintained as follows: The numeral 18 indicates a small water; tube that leads from the water" chamber or iacketu5- atera y perforated and formed with a needle valveseat that is adapted to be opened and closed a --.vertically movable needle valve 21;

b This needle valve- 21, as shown, is guided by a lug '22 on the pocket 19 and, at its,

upper end, is guided by a plug 23 screwed;

into the top of the said pocket. The needle operated by a float24 carried by a sma the pocket 19." With this arrangement,

heating device for the dust collecting when the level of the water 3 lowers, valve 21 will be opened and allow watertoi flow the dust collecting chamber until the of connection of the water pipe 18 to the water chamber 5, so that water will flow by gravity from said chamber 5 into the said 30,

ust collecting chamber. To further increase the efliciency of the charm ber formed within the shell 8, a p

' .of flues 26 are. passed through the upper por- 12 to the receiving end 015 tion thereof,--in a direction parallel to-the line .drawn fromthe deliver end of pi e ipe 14. O

' 'viously, with this arrangement,) the cleaned 1 air, passing upward-to the car pass around'or' in contact'with the flues 26',-

so that'it will be superheated, as well as i cleaned;w Thissuperheating of the air'will chamber 7 flushed an ltude of the water is restored and, therea u n, the said needle valve will be'ahtomati 'callyiclosed bythe said float. Here it-should" be "stated that in practice, the dust collecting-chamber will be located below the pointurality ureter must Below the flues 26, baflie plates or flanges 27ya'nd 28 are arranged in overlapping re-v lation,'so that the air, in passing upward must take a zigzag course, as indicated by arrows on Fig. 1-. The said baflie plates 27 are of annular form, but have radial arms 27 that connect. the same to the tube 16.

The baflie plates 28, are also secured to and supported by'the said tube 16 and terminate'short of the shell 8. These so-called bafile plates 27 and 28 serve to conduct heat from the shell 8, and hence, serve also as radiating fins.

jWhen the waterin the dust collecting chamber accumulates considerable dirt, the plug 10 is removed, thereby permittin the soiled water to rapidl run out an the then refilled with water, after the plug has been again replaced. The numeral 29 indicates a water a e applied to one side of the shell 8. b Vhat I I claim is:'

The combination with an explosive engine having an intake manifold and an exhaust'manlfold, of 'a carbureter connected to the said intake manifold, a dust collecting chamber 'adapted'to contain water, an I air intake tube delivering air into said dust collecting chamber below the water level thereof, a clean air tube leading from said dust collecting chamber to said carburetor,

an annular chamber surrounding a portion ofsaid dust collecting chamber and having an exhaust passage, flues extending from one side to the other of said annular chamber through the upper portion of said dust collecting chamber, and a connection from said exhaust manifold to said annular chamber for'.;deli.vering a part of the exhaust therethrough.
