INTERNAL-COMBUSTION PUMPING-ENGINE.

Application filed October 10, 1910.

Specification of Letters Patent.

atented Oct. 24, 191 1. Serial No. 586,212.

To all LU/lll/l't it may concern lle it known that I, CHARM-1S lCMMoNs, a citizen of the United States, residing at Ev erett, in the county of Snohomish and State of lVashington, have invented certain new and useful Improvements in Internal-Combustion 1limping-Engines, of which the following is a specification.

This invention relates to apparatus for pumping water.

The special object of my improveu'ients is to produce a pump in which the water ad.- mitted into a pair of drums is alternately exposed to the dynamic force generated by the explosion of combustible gases to expel the same therefrom to effect the pumping operation.

A further object of the invention is to provide a novel form of pump in which the pumping explosions will be regular and the water delivery will not fluctuate to an appreciable extent.

Having the foregoing objects and others of general utility in view, the invention con sists in the novel construction and combination of parts, as will be hereinafter described and claimed. e

In the accompanving drawings, Figure 1 is a view partly in front elevation and partly in transverse section of pumping apparatus embodying my invention. Fig. 2 is a similar view illustrating the pump controlling devices. Fig. 3 is a view from the rear of the device as shown in Figs. 1 and 2 and illustrating the valve employed in directing the combustible gases alternately into the pump drums. Fig. 4 is a sectional view taken through Fig. 2.

In said drawings, the reference numeral 5 designates a power-operated compressor for a mixture of explosive gases, such as gasolene, distillate oils, etc., which are introduced to the eompressocylinder 6 through a carbureter which is indicated conventionally at 7 in'Fig. 1. Since these instrumentalities may be of any suitable type, the construction thereof need not be described in detail in the specification.

The discharge for the gases compressed in said cylinder is through a pipe 8 which is connected by pipe- branches 9 and 9 with drums 10 and 10. Positioned at the juncture of said pipes is a plug valve 11 which,

as shown in Fig. 3,, has a duct 12 leading thcrethrough and arranged to atlord communication between the pipe 8 and either of its branches. It is designed to have said drums submerged in the body of water which is to be pumped. At thebottom of each of the drums is an inlet opening 13 provided with a seat for an upwardly opening valve 14. Discharge openings are provided at or in proximity to the bottoms of the respective drums which are connected by pipes 15 and 15 with the delivery pipe 16. Included in each of the pipes 15 is a check or non-return valve indicated by 17. Adjacent to the top of each drum is a passage 18 leading into the respective chambers 19 and 19. Said passages are each provided with a valve 20 opening inwardly with respect to the drums and mounted for horizontal movement with stems 21 which operate in guides 22. Provided for each said vali'c and positioned in the respective chamhers is a float 23 which is carried upon one arm of a bell-crank 24 whose other arm 2-1 is connected with a valve-stein 21 as by extending through a slot in the latter.

Supplementary bell-cranks 25 are provided in the respective drums and have one arm 25 of each connected with the valves 20, as by extending through a slot of a stem 21, while the other arms of these bell-cranks are connected with the valves 14 by 'ods 26, thus causing the valves 14 and 20 of each of said drums to open or close only in unison.

27 represents vent pipes extending from the top of the chambers 19 and 19 for the escape of the spent gases produced by the explosions occurring in the drums. 28 represents strainers provided for said drum inlet openings.

The aforedescribed valve 11 has secured thereto an operating arm 29 extending upwardly and near its extremity is pivotally connected to the lower end of a rod 30. This rod extends through an aperture in and to a distance beyond a swivel-pin 31 which is socketed in a fixed support 32 which, for example, may be secured to the pipe 8 or an attachment thereto. The axis of the pin 31 is disposed to be in the same vertical plane with the axis of the valve 11. Interposed between the valve arm 29 and the pm 31 there is carried by rod 30 a helieat spring 3555. Located at opposite sides of the valve arm 2!) is a pair oi? axially ahncd cylinders 34 and 34- which communicate from near their outer ends by tubes 35 with the pipes t) and t). A. piston .Sti is pre- \ided for each cylinder and have their rods 37 extend through the inner ends oi the respective cylinders. An enlarged head 2-58 is provided upon the piston rods exteriorly oi the respective cylinders and are normally held against the ends of the latter by springs 3t) acting against the pistons and within the cylinders.

40 and 40 represent terminals of normally incoi'nplete electric circuits 41 and 41 which include sparking appliances 42 and 42 introduced either in the top ends of the drums 10 and 10, but preferably in the pipes 9 and 9 communicating therewith so as to be located above the height at which the water ascends in the drums. To close said electric circuits there is employed switch elements 43 and 43 desirably ormed in the shape of bell-cranks havin depending lingers 44 and 44 which are a apted to be swerved by the end of the rod 30 to swing the first encountered one of the switch elements into position to close the circuit gap and in opposition to the springs 45 or 45 which act to retain the switch elements in inoperative positions.

It is to be noted that the drums 10 and 10, bein submerged in water, will naturally be fille with the same when the respective intake valves 14 are open coincidently with the valves 20 to allow the water to enter by the former and the escape of gases from within the drums through the vent pipes 27. In operating the invention, however, the water is admitted alternately in the two drums and when one of them, as 10 for example, is filled or nearl so with water, the chamber 19 is floode resultin in the raising of the associated float 23 an the closure of the valves 20 and 14 through the medium of the bell-crank 24. Meanwhile the compressor 5 has been operating to compress a charge of the explosive mixture which then flows through the pipe 9 to fill the space above the water level in this drum and likewise flowing through a tube 35 into the c linder 34 until the pressure therein is so cient to overcome the power of the spring 39. Whereupon the piston 36 is forced toward the other end of this cylinder causing the piston rod 37 to push a ainst the valve arm 29 to swing the same with the rod 30, which is pivotal y connected thereto, be end a vertical lane extending through t c axis of the va vs 11. After said valve arm and the rod 30 have been swung the spring 33 asserts itself to carry the valve arm and rod into the positions in which they are respectively indicated by broken lines a and b in Fig. 2. When the rod 30 is thus swung, the finger 44 of the switch element 43 is engaged thereby to swing such switch element into closed position with respect to its electric circuit 41 and afford an ignition spark to explode the charge of (fitHlllHlSlLlblQ previously admitted above the water in drum 10. When the explosion occurs, a pressure is created upon the water surface to drive the body oi water downwardly in the drum [0 and discharge the same through the outflow pipe 15 into the delivery pipe 10. When the water is thus driven from the drum 1.0 the weight of the water within the compartment 1!) opens the valve 20 and then empties into the drum to be replaced by the gaseous combustion products which escape throughthe vent pipe 27 accelerated by the water which again enters through the inlet 13 of this drum. The ultimate swii'iging movement of the valve arm 29 having meanwhile affected the valve 11 to close communication between the pipe 8 and the pipe 9 and at the same time afford a delivery of a charge of explosive gases from the compressor through pipe 9 into the drum 10 subsequent to the filling of the drum with a charge of water, and eventually the aressure of the gases will act on the piston in cylinder 34 to actuate the valve-arm 29 for the reversal of valve 11 and to swing the rod 30 to effect the explosion of the combustible present above the water in. drum 10 to drive the water therefrom through pipes 15 and 16.

It is to be noted that, with the duplex type shown, the explosive impulses with which the water is forced are successive and continuous; also that the number of drums or pairs of drums and their connective and synchronizing mechanism connected to a single discharge pipe or that may be coupled to a single compressor may obviously be varied in accordance with the demand, itbeing deemed sufficient to the understanding of the invention to illustrate it in the present manner.
