GAS-ENGINE.

Application filed December 18, 1903. Serial No. 185,383.

To all whom itmy concern;

Be it known that I SAMUEL J. \Vnnn,a

citizen of the United S1ates,.residing at Minden, in the parishof lVebster and State ,of Louisiana, have invented certain new and useful Improvements in Gas-Engines, of which the following is aspecification.

My invention relates to gas engines in which the piston may be operated e ther by burning or .exploding agaseous mixture, and consists in details of construction whereby to com-press the air and combine it with vaporized oil to form an explosive mixture, while maintaining the cylinder in a comparatively cool condition, as fully set forth hereinafter and as illustrated in the accompanying drawing, in which a :Figure 1* is an outside elevation of a as "engine embodying my improvements; l g. 2 is a sectional elevation; Fig. 3 is a section at right angles to the section F ig.v 2 looking in the direction of the arrow, Fig. 1;Fig. 4, a plan-of Fig. 1; Fig. '5, a detached view illustrating the arrangement of the pump and-valve operatin means; and Fig. 6, a sectional elevation illustrating -a modification;

communicates a port 8 throu which air may pass from a pipe 9 -provi' ed with a-check val-velO opening iiiward, so that as the piston rises, air is drawn into the casing M, and as the piston descends, the air is forced out of thecasing and through :1 pi e 12 provided with a check valve 13, an is forced into the chamber 1, through the port 2, the chamber 1 being of such dimensions that the air will be compressed therein. The air from the chamber 1 ma be carbureteyd in any suitable manner but the lie-piston and the casing D leg iniectedinto the casing D against the pipe 5 the oil will be vaporized, and I provide means forcarrying the air from the chamber 1 into the casing l) where it. will, mix with the vapor of the oil and pass down the pipe 5 into the cylinder in the form of an expanding gas either Patented July 2,1912.

burning or exploding according to its character, the ignition after the engine has started being effected by the heat of the pipe 5 within the casing D.

The oil is forced by a pump F, or otherwise at the proper time, into a pipe 15 communicating with a spray or nozzle 16 arranged within the casing D to direct the oil onto the pipe 5.

The air passes from the chamber 1 through a pipe G having two branches 17, 18, thebranch 17 communicating with the casing D and the branch 18 with thepipe 5 Inthe line of the pipe G is a valve J so constructed that according to its position, .there may be a passage through-the pipe-G;- and branch 17 to the casing both branches 17 and 18 to both the casing D and the cylinder, 0r throughpipc G and branch 18 to the cylinder. The exhaust controlled by the .valve H may pass from the cylinder through the pipe 20 and valve H to the exhaust pipe 35.

,Thc "alve H and the pump may be .op-

and through the latter with the cylinder.

D, or through erated in any suitable manner from anymoving part of the engine. 4 The operation is such that when. the piston descends, it compresses the charge and forces it into the chamber 1, the check valve 10 in the pipe 9 closing against the pressure. v

When the piston rises, the spent gases are forced outward through the pipe 20 and valve H to the exhaust 35, the exhaust valve being open.

Vhen the piston is at the top of the cylinder, the valve II will have been turned to close the exhaust 35 and to permit the com-'- pressed air to pass from the chamber 1 through the pipe G and branch 17 to the casing D, and the oil being in ected lnto the latter, combines .with the air, forming a burning or explosive mixture by which the piston is forced downward, another charge of air being thereby compressed in the chamber 1.

if desired, pass through the branch 18 an into the cylinder as As before stated, a portion of the air may the piston descends, 11"

2o 111g 27 at one end of the link. This link 're- -35 the axis of the valve to reduoe'theextcntof thereby seducing or affecting the character I of the explosion and regulating the le!"' 3 'perature of the motor'gase's, and this is re 2 cured in any desired degree by means of the yvalve J or othersuitable ineans,'which may be set by means of a handle 23 or'otherwisc so as to permit all of the air to pass throi 1gb the pipe 17 to the explosion casing D or. so as to permit part of -it to pass to the said casing and v.part to the cylinder A, or all of it to cylinder A. Y t

,.While' any desired means may be employed for operating the pump and the valve H, Iprefer to operatethe valve -H by is. means of a reversing link K pivoted at one 1 side to an arm or rod 24 whi'chswings upon the shaft E' as a fulcrum, the said link being reciprocatcd by an eccentric 25 on the shaft; the rod 26 of which is connected to a comes a pin 28 at the end of an arm 29 on the plug of the yalve H,-and'by-shifting the link, the action of-the valve may be reversed, this shifting beirlg readily accom- 25 plished bygraspinga handle 30 extending upward from therod 24, which may be held in position by thejnotches on the bar 36. The pump.F.;may be operated. from, the arm 29 throughlthe me'dium of arod 31' and 30 toadjust the ,-.thr ow"of said rod. itl may be 'connected at the upper end to a pin 32 which may. be set. in any, desired position in a forkedslot 33 in the arm 29. The fork in the slot permits the pin 32 to be set. below movement. y

The charge in the explosion casing D maybe fired in starting the engine through the medium-of a firing tube 34 heated by a 40 torch, or by an electric spark or otherwise. When the engine stops, the pressure of air under the piston will cause it to rise and hold it near the top of the cylinder, and if the valves of the casing I do not leak it will retain the air under pressure and the engine can be started'in either direction by shifting the link, admitting air to the cylinder, whichwill force the piston down and caiise the engine to rotate, thus forcing oil into the chmber D, which mikes with the air is i ted.

I'Lfio not wish tolimit-myself to this pai ticular construction or to a single cylinder engine, for'in some cases it may be desir- 65 able to have a plurality of cylinders to avoid dead centers, which will admit of easy starting. 4

It is not always essential to charge the chamber 1 by compressing the air by means of the piston 6. -F0r-instance, as shown in Fig. 6, there is a separate air pump oylin-; der 40 having a piston 41 connected with a crank on the shaft E and. the air may be forced from the cylinder 40 into the chamher 1 through the medium of a pipeprorapidly securing a combustible or explosive mixture. Further, the body of compressed air in the chamber 1 serves when the rever'sing link is shifted to -first arrest and then reverse the engine. f

It will be seen that the shifting of the link both regulates the cut off, by varying the opening of the valve H, and simultaneously varies the throw of the pump. \Vithout limiting myself to the precise construction and arrangement of parts shown and described, I claim as my inven-- t10n:-'" Y 1.
