To all 'whom it may concern:

Be it known that I, HENRY K. SHANCK, a citizen of thefUnited States, and resident of Cleveland, county` oi Cuyahoga, State of Ohio, have invented certain new and useful Improvements in. Gas-Generators or Explosion-Engines, of which I hereby declare the following to be a full, clear, and exact de# scription, such as will enable others skilled in the art to which it appertains to make and use the same.

The objects of the invention are to providea quick running or two cycle engine in which .the exhaust containing the products of combustion shall be practically odorless owing to the perfect degree of combustion of the gases obtained.

The objects are also to obtain increased power and eliciency in the engine by supplying a more intimately commingled mixture of gas and air to the explosion chamber under pressure.v This intimate mixture is produced not by inspiration of air or injector action nor by means of a carbureter of the ordinary type, but the lluid is forced through an exceedingly minute opening with a ressure `of from 120 to 150 pounds, where y it becomes a mere mist or vapor so that the air surrounding the jet is immediately incorporated therewith and the mixture is combustible to a degree unknown in dripping or sponge like 4carburete'rs where the explosive oil is merely atomized or provided in minute drops. For this reason a heavier and cheaper i'luid can be employed in an explosion engine, such as -a hydro-carbon or [luid rich in' carbonsu'ch as benzin, without danger of incomplete combustion Yand consequent depositl of carbon on the sparking contacts, or

disagreeable odor.

The invention consists in the elongated air and gas commingling chamber applied to an especial -form 'of preliminary compression chamber as shown in my fori'ner ap lication No. .166,233 and inthe needle va ve controlled inlet orilice for lluid, through which rojected longitudinally through the air and tne chamberin the form of a inist.

It also comprises .instrumentalities' for automatically forcing theV luid through the minute annular opening inthe valve 'at' a high degree of pressure, since by extreme pressure only can the fluid be forced through an opening thin enough to form the cloud or mist required for complete commingling with the air.

The invention also comprises instrumentalities for equalizing the pressure so as to make it continuous and instrumentalities for adjusting the supply of iluid and air to the comminglinor chamber to respond to the required speeil andV varying load upon the 'en'- me. g The invention also consists in the combination and arrangement of parts and construction o'f details as hereafter described, shown in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of the device; Fig. 2 is a side elevation thereof; Fig. 3 is a vertical longitudinal section through the commingling chamber and one of the twin cylinders' lof the engine and also through the condensing chamber for that cylinder, and transverse passages leading to both coinmingling chambers; Fig. 4 is plan view ofthe outer portion of the commingling chamber showing the adjustment levers for the fluid and air valves Fig. 5 is an end view ol' the fluid inlet nozzle; Fig. 6 is a longitudinal section (enlarged) of the outer end of the commingling nozzle, showing needle valve, and air inlet, also the valve or damper in the air inlet; Fig. 7 is a vertical section showing the pump and valves by means of which the iluid is forced into the commingling chamber 5 Fig. 8 is a transverse section thereof and of a hand pump by which the initial pressure can be obtained before starting the engine; Fig. 9 is a plan view of the same.

The engine is shown as a multiple cylinder engine, having twoworking cylindersl, 1, each of which is I rovided with a separate compression chamber 3, which chambers are connected by a trunk or passage 4, which conducts the charge to both of said chambers,

communication between the latter and said,l

chamber and fluid ment being such that the compression stroke of the piston draws the charge from the trunk 4 into said chambers from which it passes into the cylinders through the portsv 6, 6, when the pistons uncover the same on their outward or working stroke.

The vcomminglin chamber is common to both cylinders in W ch the mixture is alternately used, and comprises the tube 7 entering the transverse assage' 4, by means of a reduced inlet 8. n the outer end of this tube or chamber is axially placed the nozzle 9 provided with the lateral inlet tube 10 for oil.V

The nozzle 9 is tapered at 11 where it enters the chamber, and a long needle valve 12 controls a similarly tapered o eningin the nozzle. The valve stem is t eaded at 13 for minute adjustment and the valve is rovided with a shoulder 14 by means of whic all p ossible flow of oil can be shut off from the commingling chamber. i

'l e long taperA of the needle makes together with the screw the finest adjustment ossible and the lever 15 upon the valve stem 1s designed to rotate only througha part of a circle, since the desired opening is so minute as to require extreme pressure to drive the oil through.

.At one side of the chamber is the air inlet 16, controlled byfmeans 'of the rotaryvalve 17.

To enable the fluid inlet and'air controlling valves to operate in unison so that the requisite proportions ofair and gas shall be mamtained a governor 18 is employed to regulate their movements. This governor is operated by a sprocket or band Wheel 19 connected with a similar Wheel 20 upon the engine shaft '21, by means of the band or chain 22,'and

pivoted to thegovernor rod 23 is seen a lever 24(pivoted at one end to the engine bed-25 an at the other end to a link 26 which is connected directly to the lever 15 operatingthe valve stem in the oil inlet nozzle.

A rock arm 27 connects the lever 1'5 and a crank arm. 28 ofthe axial rod of a disk valve gine shaft, the oil is raised past the valve 34, which prevents its return, and is forced past the spring pressed valve 35 and through the ipe 36 to an-air chamber 29 the air in which 1s compressed as the oil enters, and which maintalns the degree of pressure and also equalize it to produce vacontinuous flow.

Thence the oil passes throughthe pipe 37 to the commirigling chamber.

38 is the oil reservoir, 39 the pipe leading therefrom to the ump,v and 40 is an overflow pipe leading ack to the reservoir and provided with the valve 41, which contains a s ring and relieves excessive ressure.

he commingling chamberis s own to have a reduced extremity 8, and to lie horizontally in this manner providing a receptacle for overflow of oil in case a careless operator should leave the valve open fora long time, and in this manner the flooding of the engine will be prevented.

A hand pum 50 is used to obtain initial ressure-upon t e oil in the air chamber beore t e engine is started.
