GEORGE E. SKAGGS, 0F ST. LOUIS, MISSOURI.
T0 all whom it may concern Be it known that I, GEORGE E. Simcoe, a citizen of the. United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Motors, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains t0 make and use the same, reference being had to the accompanying drawings, forming part of this specication.
My invention relates to motors of' the type wherein an internal combustion engine is combined with Va turbine, the principal ob-A ject of my invention being to provide a comparatively simple`- apparatus for economically generating power by combustion or explosion of gases or liquid hydrocarbon vapor.
In the operation of internal. combustion engines such as areV now in general use, it will be understood that a comparatively high degree of pressure is developed at the instant the explosion of the gases in the cylinder takes' place and I propose to utilize this pressure for the operation of a turbine, and which latter is arrangedto drivev the piston of the compressor for the gases or .hydrocarbon vapor.
A further object of my invention is to provide means4 adjacent to the. combustion chamber of the motor for automatically permitting unexploded gases to discharge from said combustion chamber to atmosphere in the event that a charge of combustible gas is drawn int said chamber and for any` cause whatever, fails to ignite, thus preventing explosive gases from being delivered .into
the burnt gas pressure tank.'
With the foregoing and other objects in view, my invention consists in central novel features of construction and arrangement of claimed and illustrated in the accompanying drawings, in which- Figure 1 is adiagrammatic view of a motor of my improved construction with parts thereof in vertical section. Fig. 2 is a sectional view of the cylinder in which the gases are exploded. Fig.' 3 is a 4plan view of the gas explosion cylinder. Fig. 4 is an enlarged sectional view taken approximately on the line 4.-.4 of Fig. 3.
Referring by numerals to the drawings which' illustrate the preferred embodiment of my invention, 10 designates a suitable Specication o f Letters Patent.
turbine,l the shaft '11 of which carries a worm 12 which drives a worm wheel 13, the same being mounted on a suitable shaft4 14.
Fixed on this shaft is a crank 15 -to which ,Patented July a', 191e.- Applicaton'led J une 10, 1915. Serial No. 38,350. i
is connected one end of a pitman'l, the opg;
posite end being connected to a cross head y17 which operates between suitable guides 1 8.
Arranged a suitable distance away from the turbine is a compression cylinder 19 provided at one end with a head 20 andoperatin through a stufling box in the center of.'
said head is a piston rod 21, the outer end of which is lconnected to cross head 17.
Fixed on this rod within cylinder 19 is `a piston 22.
Leading through the head'20 to the space within the compression cylinder is a tube 23 in which is located an ordinary check hydrocarbon from a suitable source of sup-,c
Y Located adjacent to cylinder 19 is 'anex-` plosion cylinder 25, the same being closed at both ends and arranged within said cylinder is a piston 26, vthe same being carried by piston rod 21 which latter operates through one of the heads of said explosion cylinder.
Leading from .thechamber within cylinder 19 to the chamber vwithin cylinder 25 is a tube 27 in which is located a check valve 28, the saine being arranged to prevent the passage of gases and the "pressure thereof from the explosion cylinder 25 to the compression. cylinder 19. e
Located in the head at the forward end of the explosion cylinder is an ordinary spark plug 30. Leading upwardly from the forwardend of cylinder 25 is a vent pipe 31 in which-is located a valve housing 32,
and leading from one side jof said valve housing to a pressure .tank 33 is a tube 34 in which is located a check valve/35.
Formed through the side of valve housing 32 opposite y.the point to which pipe 34 connects 1s an opening'36 ,and arranged for ort 38 which, when the valve-is 25 is an upwardly projecting tubular member 43, and formed in the central portion of the opening therethrough is an annular shoulder 44. The space within this tubular member below this shoulder is slightly smaller than the space above said shoulder and mounted for operation in the lower chamber is a piston 45 which is carried by a piston rod 46, the same operating through acap 47 which closes the upper end of said tubular member 43.
Loosely mounted on the piston rod 46 within thechamber above shoulder 44 is a piston 48 and interposed between said piston and the cap 47 is a compression spring 49, the same normally maintaining piston 48 on the shoulder Fixed to the upper end of piston rod 46 is an angle bracket 50 in which is seated a pin 51, the same extendingy through slot 42 in arm 41 and projecting outwardly from the angle bracket is a pin 52.
Positioned on the upper portion of the rod 46 between cap 47 and angle bracket 50 is a compression spring 53, the same being comparatively lighter than the spring 49. yPivotally mounted on a iixed support 54 directly above the free end of the-arm 41 is a spring-held detent 55 provided on its lower end with a hook 56, which latter is adapted to engage beneath the pin 52 when the latter moves upward to its limit of movement with the piston rod 46.
Fixed to the side face of detent 55 nea-r its lower end is an outwardly projecting pin 57. Rigidly fixed to piston rod 21 is the lower end of an upwardly and outwardly curved arm 58, and formed on or fixed to the upper end thereof is-a horizontally dis- )osed Harige 59, the outer portion of which is inclined as designated by 60 and this flange is adapted to engage on top of pin 52 as the piston rod 21 moves outwardly to carry the kpiston 26 to the forward end of cylinder 25.
Formed on the upper portion of arm 58 and practically in vertical alinement with the rear end of ange 59 is an upwardly projecting lug 61 which is adapted to engage against pin 57 carried by detent 55 at the time piston rod 21 and parts carried thereby Y reach the forward limit of their movement.
The operation of my improved motor is as follows: Valve 40 isy opened to permit ton rod 21 is reciprocated and as pistonv22 carried by said rody moves to the lower end of cylinder 19 or away from head 20 a charge of gas or vaporized liquid hydrocarbon will be drawn through pipe 23 into cylinder 19. On the return stroke of piston 22, this charge of gas or vapor will be forced through pipe I27, past check valve 28, into cylinder 25 and by reason of the fact that said cylinder 25 is relatively smaller than the cylinder 19, the charge of gas or vapor will be compressed within said cylinder 25. Pistons 22 and 26 are 'xed on piston rod 21 so that they occupy the same relative positions in their respective cylinders, and when piston 22 reaches the forward end of cylinder 19 on the compression stroke, piston will occupy relatively the same position within cylinder 25. `When piston 26 reaches the forward end of cylinder 25 or immediately after it begins its movement toward the lower end of said cylinder the timing device in the electric circuit in which spark plug 30 is located closes said circuit to produce spark, and thus the compressed charge within cylinder 25 in front of piston 26 is ignited.
Normally, pistons 45 and 48 occupy the positions as seen in Fig. 2, near the center of the tubular extension 43, and when so positioned, arm 41 is held in a horizontal position with port 38 at a neutral point. The
explosion in the cylinder 25 creates for an instant a comparatively high Vdegree of presy sure, and this high pressure overcomes the resistance oiiiered by springs 49 and 53 and forces pistons 45 and 48 upward, consequently raising thefree end of arm 41 and rocking valve 37 so as to bring port 38 into position to establish communication between pipes 31 and 34. As piston rod 46 is moved.
upward at the time the explosion takes place. pin 52 will ride past hook 56 and be engaged thereupon, and thus arm 41 and Valve 37 are held in their shifted positions. Immediately V'after the explosion takes place and the valve has been actuated as just described, piston 26 vwill move to the lower end of cylinder 25 and the burnt gases, which, it will be understood, are compressed' to a considerable degree, will find exit throughpipe 31, port 38, pipe 34, and pastV check valve 35 into pressure tank It will be understood that when the piston rod is moved upward at the time'of the explosion in cylinder 25, pin 52 is carried upward out of the path of travel of flange 59. Arm 58 moves forward with piston rod 21 and at a point just prior to the time the piston 26 reaches its forward limit of move-' ment lug or shoulder 61 will strike against pin 57, thereby actuating detent 55 which movement releases pin 52 andunder the influence of springs 49 and 53, piston rod and pistons 45 and 48 will move downward to their normal positions, and consequently/returning valve 37 to normal position.
In the event that the charge drawn into :cylinder 25 fails to explode,"it will be necessary to exhaust said unexploded charge to prevent its entering pressure tank 33, and such exhaust is brought about in the following manner: When a charge fails to explode, the pistons and 48 and piston rod necessarily remain in their normal positions and on the succeeding forward stroke of piston 26, the inclined portion 60 of flange 59 Will engage pin 52, thereby moving the same downward, and consequently actuating arm 41 and rocking valve 37 so as to bring port 38 in position to establish communication be.- tween pipe 31 and outlet 36. During this movement, piston rod 46 moves freely through piston 48, and such movement only necessitates overcoming the resistance offered .by the comparatively light spring 53. During the time pin 52 is positioned beneath the horizontal portion of ange 59, valve 37 is maintained in open condition or to permit the discharge of the unexploded charge from cylinder 25 through pipe 31 and outlet 36 and as pin rides onto the inclined portion of said flange, spring 53 will act to return the piston rod and `valve operating arm 41 to their normal positions. Thus, a charge of unexploded gas which would otherwise pass into and mix With the burnt gases in the pressure tank is automatically discharged to atmosphere. i p
It will be understood that my invention is applicable for a number of compression and explosion cylinders arranged I side by side,
' and itis believed that such arrangement Will .have a comparatively greater degree of eiiiciency than Where single cylinders'are employed.
In some instances it may be found desirable to dispense with the spark plug in the explosion cylinder, and to ignite the eX- plosive charge through high compression as is the practice in the Diesel type of engine. It will be readily understood that minor changes in the size, form and construction of the various parts of my improved device can be made and substituted for those herein shown and described, Without departing from the spirit of my invention, the scope of which is set forth in the appended claims.
