This invention relates to improvements in 011mg systems for pumps/or compressors, and
consists in the novel construction hereinafter disclosed. V
An object of the invention isto provide, in connection with, an air pump or compressor,
an oil separating chamber-having a distribut illustratin the assembly ofelements and cer:

. pump which constitutes the common drive for" Fig. 3 is a perspective. view of the pump.
' Fig. 4 is a vertical section through the oil separating device.
Fig. 5 is another view of the same element taken on the line 5-5 of Fig. 4.
As illustrated in the drawings the system is shown as incorporated'in a gas generating apparatus which 15 fully described in my co-- pending application Serial No. 427,923. I V The parts of the gas generating apparatus with which the present, invention is associated comprises generally an air pressure tank 1 wh ch the pressure is supplied by a pump 2 through a pressure line 3 that leads through an oil separator 4, the oilseparator being connected w'th the ti 1 1 b 5. n
" 1 run y a plpe between'the openings to the pipesf3jand 5 The pump 2 is driven by a motor 6, the motor shaft 7 being connected with the pump shaft 8 by a coupling 9. The air supply is delivered from the tank 1 to'the carburetor '10 through a pipe 11. and a fuel supply'is delivered to the carburetor 10 from the fuel 12 having a fuel supply pipe 13 and a fuel delivery pipe 14. The pipe -;.i 13 leads from a source of fuel supply,
and'the pipe 14 leads to the c'arburetOrlO. The pump 12 is driven from the shaft ,8
both the air and the fuel pumpsfiltj is with these parts that the construction of he present invention is primarily designed to be associated.
A suitable form of air pump is illustrated in detail ig. ear 'the'drawings, although it should beunderstood that otlier 'form's of umps maybe employed in the system, if desired: The pump illustrated is of'therotary type and comprises a pump. cylinder- 15 hav 1 ing heads 16, thecylinder being supported'by t6 legs or. standards 17. Within the eylihder. is "a rotating piston 18 having a plurality of hinged Wings 19- connectedtherewith. The
piston is driven from the'shaft 8 with which. 7
it is operatiyely 'connectedbya cam '20; The
pumpis mounted'in a housing 21 at the bot:
tom of'whi'ch i'sian oil well 22, to which oil is suppliedby a fille'rpipe 23. Within the well 22v is a transverse wa ll'24 forming a sump from which oil is withdrawn through a pipe 7 r 25 that leads into the pump chamber... ;The
oil thus drawn intothepump chamber serves tolubricate the moving parts'ofthe pump and a portion (of which entrains'with the air 7 stream and isdeliveredthmugh the pipe 3 intd-the oil separator. J if.
' The-oil separator is illustrated, in detail'iil Fig'sj 4and j5, and compris'es a cylinder'26' havinga bottom wall27 and a top cover Tlie-ezftremityof the pipe 3connects into a This 'r'ibi serves as a balfie wall against which? the incoming current of air impinges,=caus} inggravity separation'of theoil from the air, the oilf accumulating the bottom of the cylinder, 26. The'airpasses outwardly from;
the entrained'o'iLf.v
. the cylinder-throughthepipe B fI eedffrOIh' 1 within the, cylinder '26 as a float '32. I
float'32*has" a T stem 33 eit ending upwardly,
the upper end "of whichojperates )in arecess formed in a boss"34 carried b'yithe at .31:-
The float 3 2Rhas' a downwardly extending stem 35in axial aliiiementwith 'thestein 33-:
Thelower"extremity of the stem 35a tapered to form a needle valve 36 and operates to control an outlet passage 37 in a valve member 38 at the upper end of which there is a valve seat that cooperates with the needle valve 36. The outlet pipe 39 connects with the passage 37 for delivering oil from the 011 separator when the oil level in the cylinder 26 reaches a height sufficient to raise the Valve 36 from its seat. The purpose of maintaining a level of oil at the bottom of the cylinder 26 is to form a seal for the upper part of the chamber and to provide a body of oil for the lubricating system.
The pipe 39 connects with a header 4:0 that extends across the upper part of the housing 21. .A pair of tubes lllead from the header 40 to the bearings of the-motor 6, and a-tube 42 leads from the header to the operating connection between the shaft .8 and the pump 12 and a pair of tubes-43 lead from the header 4:0 to the bearings of the pump 2. Thus there is. a complete distribution of oil from the bottom of the chamber 26 .to the op erating parts of the motor,.the fuel pump-and the air pump. v
At the bottom of the oil wells about the motor bearings are pipes 44 that connect with a manifold 45 leading back into the housing21. so that any excess oil is conducted back into the well at the bottom ofthe'housing 21 fromthe motor. Since the fuel and air pumps are within the housing 21 any excess oil drips from the bearings and operating .parts into the :oil well for re-circulation. V
While the details of construction .of the pump 12are not p artof the present invention, the pump has been illustrated to show its association with the drive shaft. The pump receives a supply of fuel through a ,pipe 13 whichdelivers the fuel to a chamber 47. The chamber 4 7 is in communication with apump chamber 48 through a passage 49. The passage 49 is controlled-by an-outwardly operating valve 50..
Inthe chamber..48 is a spring .operated diaphragm 51, the spring normally actuating the diaphragm toraised position. The diaphragm has a downwardly extending stem 52 that is connected with .a bell crank lever-53 by toggle links 54. The bell crank lever .53operates in opposition to a spring 55 hearing against the inner arm of the lever.- A-cam 5.6 is carried by the shatt-8,'-said'cam 56 contacting with the .free end-of the bell crank lever 53. As the shaft 8 rotates the bell crank lever 53 is rocked and, through toggle link connection with the stem :52, the
diaphragm is actuated. When the-toggle links are drawn downwardly, the downward movement induced thereby'on thediaphragm causesa suction in the upper part ofthe pump chamber drawing fuel from the chamber l7 into the pump chamber. When the dia- I phragm is forced outwardly the contents of the chamber 48 is expelled through a valve 57 to the fuel delivery passage 14:.
It is obvious that with this construction of pump constant lubrication of the connection between the bell crank lever 53 and the cam 56 is required for eifici-ent operation, and this is accomplished by the air continually supplied with oil through the pipe 42 when the apparatus is in operation.
I am aware that the invention may be modified in certain particulars without departing from the spirit and scope thereof. I do not limit myself unessentially, but what I claim and desire to secure by Letters Patent is 1. In an apparatus of the class described, a pump, an .oil sump, an oil inlet for the pump leading from the sump, an air supply from the pump, a chamber into which the air supply discharges, an air outlet for sa1d chamber, a baflie located between the air inlet and outlet, a float in said chamber, and a discharge passage controlled by said float leading to said sump.
2. In an apparatus of the class described, a pump, an oil sump, an oil inlet for the pump leading from the sump, an air supply from the pump, a chamber into which the air supply discharges, an air outlet for said chamber, a bafiie located between the air inlet and outlet, a float in said chamber, a discharge passage controlled by said float leading to bearings in the apparatus requiring lubrication, and means toconvey the oil from the hearings to the sump.
