To al'whom it may concern;
Be it 4known that I, Hnnvincnrv SH'nLnrN, a subject oftheGerman Emperor, and a. resident. of TWiesbaden, Gerinany, have invented certain new and useful Improvements in .Gas-Engines; and I the following to be' a full, clear, .and exact description of the invention, such as will enableothers'skill'ed in the art to which it.- appertains. to make and use the-same, reference the accompanying drawings, and tolettersor figures of reference marked thereon, whicliform a part of this speciica.- tica.
- The inventionrelates tofimproyements in explosive gas engines particularly to that type ot'engine in which the explosions occur on. 'each -shide of the working piston alternately,so that there will be two impulses for each 'revolution-- The object of my improvement 'is to provide.y an" engine 4which. combines simplicity 'with a' high elii'ciency and consists principally 'in the novel arrangement of inlet ports, the cylinder and the coo perating piston.
In the drawing accompanying and forin'- tinge-part of this specification I have shown 1n .detail .certain advantageous forms of embodiment of thel invention which will be st forth'ixr detail in the following description while. the noveltyof the invention will be lincluded in the claims succeeding said den scription.
Referring: to said drawing z-.fFigure l-'isa longitudinalvertical section of 1an engine embodying the novel featuresof myinvention.' Fig. 2 a horizontal section on line .2-2 ot' Eig; 1.

F 1g.y el a vertical section on line 4 4 of F ig.` 3. Figga view similar to Fig. 3 of a modiiication.
Corresponding and like parts are 'referred to'in the following description and indicated inthe several views of the drawing. by the same reference characters.
The engine consists in general ofa working cylinder com osed of end sections 1 1 and a central sectlon 2: two cylinder covers 3 an 4, a -power piston 5, a piston rod 6, vassing substantially gas tight through aV 'lateral extensions 9, a 'pump ll, the pistons do hereby. declare l 1well known construction tudinal passages 12,
' to form `of the partition `and the parts connected thereto 'of `being bolted to a suitable bed plate or ;foundation.
stuliing box 7,' a cross-'head 8 having two gaspuinp 1G, an air ofsaid pumps being connected to extensions 9 of the crosshead and the necessary parts to govern and transmit the'power -of the piston. These last mentioned parts may be of any desired and andas they form no part of myinvention, they have -not been illustrated. The section 2 is divided `into two longi- I 13 by means ofa sinu-y ous partition 14 as shown in Figs. 3 and 4,01 by a lzig-zag partition 14a' shown in F ig. 5fl
On the gas side 13 of the partition is termed a bridge 15 having a channel connecting the adjacent turns of the sinuous partition and opening intoand'being fed from' the air side 12 of the partition'so as continuous ports` 12i for the air which surround gas ports 13a on the gas side wherebygas' can pass from the gas chamber 13 under bridge l-and up through the centralgas ports 13,a into the. cylinder.
The central provided with a. suitablefoot or flange 16v that serves to support the working cylinder and capable 'The end sections 1., 1, are provided with flanges 17 by means of which they are -fastened to the central portion 2 and also with 4'flanges 1S to which the cylinderends 3 and 4 are secured.
The parts1,2, 3 and 4 are each provided with tongues and grooves to form an abutting and alining joint, wherel'iy the parts can be accurately centered. heads or covers 3 and 4 are similar in construction, except that the 'one 4 is provided portion 2 of the cylinderis' rihe cylinder.
with la stuiling boi:v 7. The spaces 21, at the ends of the cylinders, serve as the so-called explosion or compression chambers. In each cylinder-head is a suitably shaped pocket 22., in which is located an exhaust valve 23 andy if necessary, more than one exhaust valve haust. valves may be of lany suitable construction and are'here shown as the common puppet valves that' are mechanically operated by any suitable mechanism', not shown.
`may be used at each cylinder end. These eX- The heads 3 a d4 contain a suitable ignition device, ele tric igniters 24 being preerred, though any other suitable igniter' may be used. rIfhe cylinder heads are pro vided with Water chambers 25 and 26 'for the circulation of cooling Water and the 'sections l, 1 are each lprovided with a casing 27 that also` forms 'spaceffor the circulation of cooling water. Since the central portion 2 of the Cylinder is only exposed to a fraction of the heat of explosion it need not necessarily 4be provided with a water jacket.
Thecylinder may be formed in onel piece, but thel composite structure described is preferable, the chief advantage of which is hatthe unequal expansion ot' the cylinder is avoided, a perfect alinenient oit the cylinder is maintained and the cylinder ends l, l, that are exposed 'to the greatest heatlofexs plosion mayjexpand freely to either side 4of vthe part 2, without aiiecting the relative positions of the inlet ports and the working piston. A The piston 5 may be designed and fixed to the piston rod 6` in any suitable manner and the length of the 'piston must be slightly less than the stroke in order to clear the inlet ports when the piston is at vthe innenand outer dead points, cylinder are charged by a single series of ports.v
ing ianges Q9, in the center ot which are turned-out recesses `to receive the thickened portion 30 of the piston rod 6. The enlarged portionBO is prete ably in the form ot' a double cone. The two parts 28 are bolted together by bolts 31 that pass between the flanges Q9, the double c oned end of the pis ton rod being held 'securely within the recesses in the flanges. The. ends ofthe piston are closed by plates or caps 32 and the opening in one of them for the piston rod is made gas tight by a ring The piston itself is provided with packing rings 34 as is custoniary. l
The piston rod fl is fastened to the crossliead 8 `and passes through a stuffing box 7 Theypiston consists of two parts 2S, havv in the cylinder-head 4.-.said box being filled with a suitable packing inaterial'held in' place by a gland 3o.
The engine is provided with two pumps l() and ll of the saine construction. pumps. which are double acting, areearranged on both sides' ot' the power cylinder and parallel thereto, and theirpiston rods 38 and 39 are connected to the arms S) on the cross-head 8, so that the three pistons 3G, 5 and 3T have equal strokes and move in unison in the saine direction.
The operation is as followsz-Let it be supposed that the compression chamber 21. near cylinder-head 4 in Fig. 2, is filled with whereby both-ends of the.
These al compressed' 'explosive charge and this charge ignited by the device :24. time the lett side of the gas pump l0 is .filled withgas, and the left end of the air pump 1l with air. The Working piston their drivenin the direction ot the arrow, both in unison. Consequently gas and air are compressed inv their respective' pumps. Af ter the piston has passed aboiit S0 per cent. of its .stroke the exhaust valve 4 is 'opened and the high-pressure gases es cape, shortly after .which the end or the pi:- ton uncovers the air ports l?? to admit. air compressed in the pump ll. ports surround the -gas ports they begin to be unc'overedby the piston iirst to admit air that rushes into the cylinder in a number et single streams from the inner periphery c't the cylinder, that impinge upon each other and thereby destroy the momentum ot' the ni#- rush ot' air. The air thus fills the whole cross-sectional area of the cylinder and ad' vances as a solid column to torce out any' l remnants ot' the products ot' combustion and thoiouglily scaienge the cylinder. A tur-- ther progress of the piston 5 willalso open the gas-ports 13a and on account otthe peculiar arrangement of theports the air and gas is thoroughly mixed to form an explosive charge, and the uniformity ot' the mixture is insured, whatever the amount of the gas admitted.-
At about the dead center the exhaust valve Q3 is lclosed and the 'piston starts on its com .pression stroke (on the saine side ot' the piston) lirst closing a part ot' the air ports and then the gas ports. Simultaneously the pumps draw a. fresh supply of air and gas on one side ot' their pistons, while that on the other side is being compressed, the piston .5 again coming tothe positionsliown in `Fig. 2., when the cycle is completed. saine operations take place on the opposite side, thereby making the engine double acting with an explosion taking place .alter-V nately on opposite sides of' the piston, or two explosions ior every revolution.
Having thus described my invention. what l claim as new therein and desii'e to secure by Letters Patent, is:- i

In a gas engine.I a cylinder having internal gas and air ports between its ends. the airports surrounding the gas ports and fi double acting power piston controlling said ports simultaneously, whereby during the travel of the piston the airports will first be partially vopened to admit air and then admit Q'as behind the stream of incoming air and nallv surround the incoming gas by a mantle of air.
