Application filed November 1, 1909. serial No. 525,930.
To all whom it my concern:
B: it known that I, DONALD J. MoKm- I NON, of the city of Toronto, Province of Ontario, Canada, have invented certain new and useful Improvements in Internal-Comv bustion Motors, of which the following is a specification.
. The problem of designing valve constructions for four-stroke c cle internal combustion motors is rendere much more diflicultthan the similar. problem in steam engines owing to the greater pressure" usually'e mployed and the frequent gesence of SOlld8 in the exhaust gases. elves thereiore which will answer admirably in the steam engine at present cannot be advantageously em loyied in an internalcombustion motor owing to the difliculties of .packing and lubrication. Among such valves constructions ,are rotary or oscillating valves such as used .in Corliss engines, --and my object is todevis'e means whereby such valves, or other. valves which for similar reasons are now unsatisfactory, may be successfully em ployed in internal combustion motors and their resultant advantages obtained.
vof .the high pressure attained during the compression nnrl explosion strokes of the motor which reduces the wear on-the valves and. makes. packing and lubricating very sim )le problems. i 1

need not be particularly described.
'projct mwer pressure of the gases from In the drawings like letters of reference indicate correspondingparts in the difierent figures. I v
A is the cylinder of an engine which is in, the main of ordinary construction and B' is thecombustion chamber in axial alinement with the c linder and of the same dinineter. This com ,ustion chamber is water as-shown, and in order to preventjt v avmg undulyafreat cap1 V y, as .s own, somewhat n the same manner as the bottom of a wine bottle. In the end is a suitable opening or openings for the insertion of a spark or other attachments Inthe, si es 0 combustion chamber are formed the" inlet port D and the outlet rt E. These orts are referably of smalle 'a xialy of the o amber but made of conslderable width circumferentially as shown particularly in Fig. 2, in order to give -the necessary capacity. Valves are provided for these ports of any suitable construction but'pre ferably of the type hereinafter described.
Relative to. the c linder-and combustion chamber a sleeve the ' is adaptedto move This sleeve is preferably made to slide within the cylinder and is provided with pack- 'ing a of anys'nitabl'e form preferably located 'ad'acent to the 11 per edge of sleeve w ich -is made 0 increased thick' ness fbr that pur ose. ,The piston- Grew the ciprocates within-t e..-sleeve F. and is given a. workin fit therein, and will, of course,
be provi ed.with the ordinary packin The function of the sleeve F is to shut o the ports of-the combustion chamber during the compression andexplosion strokes o the motor, and thus re e've the-valve :or-
valves from contact with the, gases underpressure.
" The necessary movements are imparted to the sleeve'by the following mechanism: H is -a crank shaft suitably ourneled andgdriven from the main shaft '0 the motor'by a suitable gear-in adapted to give one revolution I isha t H to-two' revolutions-pi the motor-shaft I. I'show a 'sprocketiand cran of the ham gearing J for this purpose.
60. acity its end C may otally connected to the crank and the sleeve,
' this, I prefer somewhat compression and explosion K is feirmed on this shaft which, through the medium of the connecting rod L pivuctuates the latter. In Figs. 34-5 and 6 'the positions of the centers of this mechanism are indicated by round (lots, the inner circle at the lower end of each figure indicating the path of travel of the center of the crank K. As the upper end of this sleeve opens up both the inlet and exhaust ports during both the suction and exhaust strokes, separate means must be provided to close the exhaust port during suction and the inlet port during exhaust. ous devices maybe employed to accomplish 0 form in the walls of the combustion chamber valve casings adapted to contain the oscillating rotary inlet valve and the oscillating rotary outletor ex haust valve N. These valves are of the general' type well known in connection with Corliss and similar steam en ines.v Each valve is provided with a stem on which is secured an arm 0. These arms are pivotally connected to the couplin bar 0. One of the valve stems is also provided with an arm d. To thisarm pivotal] connected onearm of a connect-1n rod the' other end of which'is pivota lyconnectedwith the crank Q on the crankshaft The desired oscil-' lating rotary movement isthusimparted to the valves M and N. As the arc of oscillation of the exhaust valve N is preferabl greater than the inletvalve hi: it will be'notedthat theiarm c o the 'stem of the exhaust valve'is rather shorter than the arm c'on the stem of the inlet valve, thus giving the desired variation in the respective arcs of travel. I In Figs. 3+5 and 6 the positions of the -"fll'l0ll5 centers of the operating mechanism for the \alvesfM and N are indicated in round dots, the outercircle at the; bottom of each figure indicat ng the path of travel of the crank Q. These-figures respectively show the ositions, of the valves M andN and the seeve' F atthe beginning of the suction stroke ofthe motor, the. beginning of the compression stroke, thebeginning of the. ex
losion stroke and the beginning of aust stroke.
the 'ex n will befseenIrom these different views" that the slfi ve'shuts otithe ports during and thus relieves the exhaust and "mien valves of pressure,
"and tha-t, said valves respectivelyclose the exhaust port dur the exhaust as desired.
do not desire to limit myself to the precise construction and location oft-he means em- "ployedjtp. relieve the valve or valves of employed to take the place ofthe sleeve whlch would the purpose of my indescribed \Vhile varito guard the valves from both of said ports during the said ports; port-dnrmg suction and the ,inlet understood, o course, that I vention. The sleeve within the c linder is and also claimed in detai as being at present considered the preferable form.
It will also be clearly understood that the valve construction shown, while at presentconsidered a preferable one, is not essential and any other suitable valve or valves might be employed instead.
In describing the action of the sleeve I use the expressions open 'up the ports and shut off the ports. but it must be clearly understood that I only use these expressions in as far as they relate to the action of the sleeve itself in opening up the ports to give them free communication with the interior of the cylinder or in shutting them off from the pressure within the combustion chamber during the compression and exhaust strokes, the being merely to act as a porteullis or shield pressure during compression and explosion.
