'INTERNAL-coMBUsTIoN ENGINE.
To all. whom 'it may concem:. I Be it known that I, JULIAN A.' Gines, a
citizen of the United. States offA'merica, 1and residentof Derbycount-y of New Haven, and State. of Connecticut, have invented cert-ain new and useful llinprovements in Internal -Coinbustion Engines, of which "the following is a specification. f
, My invention relates -to internal combus# tion. or gas engines and. particularly to the class .of two-cycle engines. The object of my improvement is to provide an engine of this class which shall b e simple and effective in its construction and operation, whichshall be especially convenient for manufacture and one in which the admission of inixture'to the compression chamber and to the cylinders and the exliaust 4'of burned gases` is controlled by the 20 movement of the pistons ,cover-ing, and un'- covering` ports suitablyarranged. j
. My invention consists in the novel eon structicns and arrangements of vparts hereinafter more .fully pointed out and ldescribed. ,v v .Inthc drawings accompanying and forming a part of'this specification, Figure l represents al section on line 1 1 of Fig. 2,'Fig. a .section on line 2--2 of Fig.` 3, Fig. 3 a
4 partial section on line 3 3 of Fig; 2', and Figs. 4 and 5 respectively a partial plan and side view of the upper end of the piston operating in the cylinder in which the com bustible charge isadmitted, and Fig. 6 represents a section online 6-6 of Fig. l liro'ugh the ports in the lower endof cyline'r 2. A
The reference .characters are used inthe same sense throughout the drawings and the specification.
The preferred form of my invention "herein illustrated and described, is designed especiallyl for power driven vehicles and similar uses and: it comprises two complete engines united in asingle frame work, each of which comprises two cylinders, two pistons and two` piston rods connected to a'sifn` gle crosshead, connecting rod and crank. The two cylinders are designated by 4numer- 50 als l and 2, respectively, the former being Specification of Letters Patent. Application fled March 19,

the cylinder4 in which the .explosive 'ch-arge 4or combustible mixture is admitted, while' the cylinder 2 is the one from which the burned gases are eahausted.l4 These cylindersare connected at their upper ends by a continuously open passage 3.` The Icylinders 1 and :2 are formedv of 'an integral casting,
' beingjoined at their upper 'or explosion end by the walls 4 of the connecting passage 3, and at their lower ends by a web 5 which web is finished to form a seat to engage a`corre' sponding'seat on tlie top ofthe com-pression' chamber The cylinder"1 terminates at this seat and has formed in its end' a recess for the reception of packing rings, as clearly shown in Fig.l l. The cylinder .2 has an end 8 which projects some distance below the lower face or seat ofthe web y5 and has a se-V ries'of ports 9 formedtherein, which ports.
when .uncovered by the upward movement of the piston afford communicationbetween the. interior of the cylinder below the piston and the annular chamber 10 y formed in-,a re-l cessed port-ion of the compression chamber'6 and surrounding the projecting 'end 8 of the' The annular chamber 10 comcylinder 2. munlcates with the passagev 11 which' 1s adapted to connect with a sourceof mixture supply, in any convenient manner. The pis' ton 12 operates in cylinder 1 and is' provided with' ports 13 which are adapted whenv the piston is in its lowest position' to afford com` nnu'iication between the compression cham ber 6 and the cyllnder 1. These ports are ar'- ranged, as clearly shown in Figs. 4 and-5, so
as to give the mixture a spiral directionas it enters the cylinder, thereby causing the heavier or unevaporated particles of' the mixture to rapidly fly outward. and make contact with the 4hot walls of the cylinder to cause their more rapid and complete evap` oration. AThe piston 14 operates in cylinder.
2. This piston is provided with twosets packing rings l5 but has no portsin it,
When .this piston is in its highest position 'its lower edge uncovers the ports 9, thereby ad.`
-f'mitting mixture from the chamberA 10 "to the compression chamber 6, and when 1t is in'its lowest position, or at the end' of its working stroke, it uncoversthe exhaustfports .1 6 in'y -50 preferably cast integrally with tlr cylinder 2. These exhaust-.ports lead to the exhaust passage 17..:The cxliaii'st"ports 16 are of triangular form, each triangular Stuiing boxes 21 aresecured to the partition 19 toprevent leakage around Vthe-'piston rods 22 which are secured to the pistons' at their upper ends -and tothe crosshead 23v at their lower ends.
In order to provide for the increased pressure ont-he crosshead pin 24, which results from havingl two istons connected to a single crosshead, an to'kee within the limited space available in engines of this class, I provide a special construction of crosshead and connectin rod which enables me to utilize the sur ace of the pin on the side on which the thrust is exerted'for its entire length. A semi-cylindrical recess 25 is formed in the crosshead to lit the curvature of. the crossliead pin 24, and a recess 26 of greater depth than the semi-cylindrical recess 25 is formed in the crosshead at right angles to the axes of the pin, to receive the connecting rod strap 27 which is here shown 4as being formed integrally with .the connecting rod28. The pin 24 is secured to the crossliead by means of the bolts 29. The upper end of' the connecting rod 28 has recessed extensionsBO which extend out on pin. By means of this construction the entire lower surface of the pin is available for bearing surface. The lower end of the connecting rod engages the crank 31 on the crank sliaft 3 2 in any approved manner. The. -crosshead works iii vertical guides formed in the hollow column 32` which is y ecompression chamber Gand is joined at its lower end to the crank i'rame33 in which are the crank shaft bearings 34. It is thus seen that the crosshead and connecting rod work in a closed case which is separa-ted from the compression 4chamber by thetransverse partition or web 19,- by means of which construction the lubricating oil contained in the crank case is prevented from mingling with the mixture and at the same time the volume of the compression chamber is limited to a more economical proportion, permitting a higher compression therein. i IIaving thus described my invention what I claim is:
