LUTHER H. WATTLES, or PRovInENcE, RHODE ISLAND, ASSIGNOR, BY MEsiIE ASSIGN- MENTS, TO FRANK SMITH, OF WARREN, RHODE ISLAND.
PUMPING APPARATUS.
Specification of Letters Patent. Patented Feb, 20, 1917.
Application filed December 29, 1913. Serial N 0. 809,191.
To all whom it may concern:
Be it known that I,.LUTHER HENRY WAT- TLES, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Pumping Apparatus, of which the following is a specification.
This invention-relates to pumping apparatus used in connection with internal combustion engines, and has for its object to provide a reciprocating pump connected direct to the cylinder of an engine of this character to be actuated by the compression in the engine cylinder, and to so connect said pump'that it will generate a pressure and force fluid to different portions of the apparatus or wherever desired.
A further object of the invention is to connect the cylinder pump to a pressure tank or chamber so that the flow therefrom will be steady and not be affected materially by the pulsations of the pump.
A still further object of the invention, When the apparatus is used in a boat, is to provide a second pump of the ejector type which is operated by pressure from. the first pump to raise and discharge the water or gases from boats, sewers, or other places,
where it is liable to accumulate, and in this I apparatus a connection may also be made where the fluid pressure from the first pump is forced through the engine cylinder jackets to cool them.
With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.
Of the accompanyin drawings:
Figure 1 is a side e evation showing my improved apparatus as connected to and operated by the action of an internal combustion engine.
Fig. 2- is a detail illustrating the compression actuated reciprocating pump as connected to a pressure tank.
Fig. 3- is an enlarged view of my impro ed reciprocating pump in section, showing a portion of the engine cylinder to which the pump is attached. I
F 1g. 4- is an enlarged sectional elevation of the pump of the ejector type which is actuated by the reciprocating compression pump.
. Referring .to the drawings, 10 designates the bottom portion of the boat in which the engine 11 is installed, the same being of the internal combustion type preferably having waterjacketed cylinders.
A feature of my present invention is that a pump P is provided having a lower cylinder l2, threaded at its lower end 13 into the engine cylinder 14, and an upper cylinder 15 connected to said lower cylinder by the ribs 16. A double pump piston 17 has its opposite ends mounted in said cylinders 12 and 15, the inner end of the pump piston communicating direct with the interior of the engine cylinder, whereby the compression in the latter forces the pump piston 17 outward against the return spring 18, and when the pressure is reduced in the engine cylinder, this spring 18 is interposed between the end of cylinder 15 and an abutment on the piston rod and acts to return the piston to normal, whereby its inward motion creates a suction through the pipe 19 and intake Valve 20, and its outward stroke drives the char e out through the exhaust valve 21 into the discharge pipe 22, thus producing a positive pumping action. The abutment on the piston rod cooperates with the end of cylinder 12 to limit the inward stroke. It will be seen that the pump-piston is thus operated by the action of the en 'ne, and as the portion of the charge W ich drives the pump outward is not withdrawn from the engine there is absolutely no waste. In fact, in practice it is found that the gases in the engine are more thoroughly mixed by the movement of this pump piston, thereby causing a better and more effective combustion in the cylinder than as though the pump piston were not connected thereto. 1
In some cases I draw the air through-the inlet valves and discharge the same through pipe'22 into the compression tank 23, from which tank the air may be drawn through adapted. I have also provided a second not shown, in the body of the ejector.
6- low the screen and in line with the chamber 12 a draw-off cock or valve 29 is positioned. The end of the ejector body portion is reduced and threaded at 30 into which an extension portion 31 is screwed and between these members is secured a plate 32 in which the jet member 33 is removably mounted. To the outer end of this extension member is connected a discharge pipe 3& secured in position by the screw threaded collar 35.
A suction inlet passageway 36 leading down adjacent to the bottom of the boat is provided, through which water and gases may be drawn by the action of the jet, from the bilge and discharged overboard through the outlet pipe 37. In order to prevent the water from siphoning back through the discharge pipe into the boat, a check valve 38 has been placed in the suction pipe to automatically shut the same off. This valve also servesto prevent the water from the jet from passing down into the bilge when the pump is running slowly. x
In practice I preferably arrange the apparatus so that the cylinder pump P shall draw water from the outside of the boat through the pipe 39, and force it through pipe 40 into the ejector 25, through the shutoff valve 41, whereby the action of the water forced therethrough creates a'suction in the to supply water to ejector to continuously raise the bilge water, and also any dangerous gasolene fumes or other gases which may have accumulated in the bottom of the boat, through the suction inlet 36, and lead, the same overboard through the pipe 37. I have also arranged cylinders by the action of'pump P through the branch pipe 42, the quantity being regulated by the valve 43. By this construction it will be seen that the boat may bepumped out and kept dry by the continuous action of the e ector pump, and a portion of the water forced from pipe P through the cylinder jackets to cool them, all by the action of the simple pump, which is automatically operated by the compression in the engine cylinder.
I Another feature of my improved pumping apparatus is that the engine may beemployed to pump liquids and gases from sewers, or the like, and where it is not convenient to force a jet of Water through the led through the jackets of the engineejector the pipe 39 is removed from the pump P and air, instead of water, is pumped through the pipe 22 into the storage tank 23, as illustrated in Fig. 2, from whence it is pipe 24: to'the ejector, whereby the pulsations of the pump P causes an air pressure to be forced through the ejector pump, the action of which pressure raises the fluids and gases through the inlet 36,
and discharges them through the pipe 37 into a suitable receptacle.
I have shown my improved pumping apparatus as attached to a boat and operated for the purpose of removing water and gases from the bilge thereof, but an apparatus of my improved construction may be employed in producing a pressure ofair or other fluid to be used for any purpose. ticular uses of this fluid pressure is for the purpose of operating a pump of the ejector type for pumping water or gases from any source and another feature is that a portion of the fluid is arranged to be forced through the water jackets of the engine for cooling the same. My improved apparatus is adapted to be used not only on stationary or marine engines, but also on engines employed for driving motor vehicles as well.
I claim:
' 1 The combination with an internal combustion engine cylinder, of a pump cylinder communicating with the interior thereof, an independent compression cylinder supported by said pump cylinder and in spaced relation thereto, means for separably uniting said cylinders, a piston having its ends working in the pump cylinder and compression cylinder respectively, and a spring interposed between the spaced ends of cylinders forreturning the piston to normal position when the pressure within the engine cylinder is reduced, and means for limiting the movement of thepiston under the action of said spring.
2. The combination with an internal combustion engine cylinder, of a pump cylinder communicating with the interior thereof, an independent compression cylinder supported by said pump cylinder and in spaced relation thereto, means for separably uniting said cylinders, a piston having its ends working in the pum cylinder and compression cylinder respectively, said piston having an abutment flange, a spring interposed between the inner end of the compression cylinder and said abutment flange for returning the piston to normal position when the pressure within the engine cylinder is reduced, said abutment flange cooperating with the outer end of the pump cylinder to limit movement of the piston under the action of said'spring. v
3. The combination with an internal combustion engine cylinder, a pump cylinder communicating with the interior thereof One of the par- 7 and provided with a bracket, 'an independent. compression cylinder provided with a bracket complemental to the bracket of said pump cylinder, means for separably unit- 10 tion when the pressure within the engine cylinder is reduced, and means for limiting the movement of the piston under the action of said spring.
In testimony whereof I afiix my signature in presence of two witnesses.
