GEORGE MODOWELL, OEYNEW YORK, N. Y.., ASSIGNOR. OF ONE-HALF TO HERBERT LA'IIIVIER, OF BROOKLYN, NEW YORK,
INTERNAL-COMBUSTION ENGINE:
Specification of Letters Patent. Patented Feb. 22, 191 i 7 Application filed February 13,1909. Serial No. 477,719.
I To all whom it may concern:
Be it known that I, GEORGE MoDownLL, a citizen of the United States, residing at No. Bay ltidge avenue, in the borough of Brooklyn, city of New York, State of New York, have invented certain new and useful improvements in Internal-Combustion Engines, certain phases of the invention being adapted also to use in steam, hot-air, and- .othcr engines, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 illustrates a horizontal section view of an engine embodying the invention. Fig. 2, illustrates an elevation of'that which is shown in Fig. 1, the pump being omitted.
Fig. .3, illustrates a vertical longitudinal sec tional view taken on the line 33 of Fig. 1. Fig. t, illustrates a transverse Vertical sectional viewtaken on the line 44 of Fig. 2 looking in the direction of the arrows. Fig. 5, illustrates a View partly in section taken on the line 5 5 of Fig. 2, looking in the direction of the arrows.
The especially important features of this invention are these: The power cylinder in which the CUlllDlQSSlOll, ignition and explosion of the charge of fuel take place is provided with'a double ended piston and with laterally disposed fuel injection cylinders each provided with a double acting piston whereby the fuel is injected into the power generating cylinder at appropriate times. All of the cylinders are closed at the ends opposed to the pistons, and are open at their other ends, that is to say, there are no openings in the cylinders in the working sections thereof except the necessary intake and the exhaust or ejection ports. 1
The wrist pin connects with all the pistons at their central parts and is provided with suitable connecting rods which engage with cranks on'thc engine shaft.
Referring to the drawings 1, represents the power cylinder; 2, 2, the fuel injection cylinders; the cylinder 1 is provided with a double ended piston 3, 3, each end of which is provided with suitable packing 4, 4.. I prefer to make the piston in two parts as shown, knuckled together at the wrist pin, 5, in a manner well known, so that its opposite ends' may have independent, movement. Each of the injection cylinders 52, 2, is provided with a plunger or piston 6, G, suitably packed at each end as shown at 7; the wrist pin 5, passes through all the pistons at their central parts as shown; 8, 8, are connecting rods extending from the wrist pins to cranks 9,9, onthe engine shaft 10; 11 is a fly wheel on the shaft; 12 are spark plugs of any suitable construction located at the ends of the power cylinder.
13 (see Fig. 1) is a pump actuated by pump rod 11 driven by the wrist pin 5, whereby water is forced to circulate through a water jacket 15 for cooling the engine in a manner well known.
The fuel from any suitable source of supply,is drawn in to the injection cylinders by thesuction movement of the pistons (3, 6, through the supply pipe 16 which is provided with a check valve not shown and branch pipes 17 (see Figs. 4 and 5) and upon the return or e ecting movement of these pistons the charge is forced through pipes 18, and check valves 19 into the power cyl inder 1. The exhaust from the latter is secured through ports 20 (see Fig. 3) one at each end of the cylinder which are uncovered by the pistons respectively after they have completed about four fifths of their power stroke. The parts are timed in such manner that these operations take place in proper succession as is now well understood. The wrist pin in its to and fro transit passes through an open space 21 made in the cylinder castings. I prefer to cast all three cylinders in two equal parts each provided with a flange 22. Whereby they'can be bolted securcly together by bolts 23 (see Figs. 2 and 5). The injection pistons are longer than the power piston consequently there is some compression of the charge in the injection cylinders before the power piston has uncovered the exhaust ports consequently. when this takes place the charge is injected into the power cylinder with some violence and this aids the ejection therefrom of the spent charge.
It will be noted that the invention is adapted to practically all forms of internal combustion engine and that so far as the piston and cylii'ider construction is concerned it is likewise adapted to steam, hot air and similar engines.
Among the advantages secured by me are the following: a) There are no openings of any kind except the inlet and exhaust portsin the vorking parts of the cylinders, consequently, reduced liability. of leakage. (b)
The construction is such that the engine receives a power impulse at the end of each piston movement. (c) The wrist pin is guided and supported. by the two injection pistons this secures stability and alinement of the parts. ((1) The construction is simple and strong-by simply removing the bolts 23, and the pipe connections the whole mechanism comes apart,' and by taking the caps ofl from the connecting rods the wrist pin can be driven right through lull the istons and th s all the piston mecha'iiism e taken out for repair-or cleaning.
Itwill be obvious to those who are familiar with such matters that the details of construction described and illustrated herein may be, widely departedfrom and et the features of the invention be utilize For example it is not essential that there be two injection cylinders because one only will operate successfully, nor that the cylinders be double-ended, because if they be singleended the engine will also operate. Also instead of having a continuous wrist pin running through the central parts of the pistons, the pistons themselves may be so constructed as toproperly engagewith each other and work together suitable devices being supplied whereby the connecting rod or rods may engage with the power piston. In short v the engine described and illustrated by me is one formfonly in "which the essentials-of the invention may be embodied.
