To all whom it may concern-.-

Be it known that I, Tuottns Varrcu, a citizen of-the' United'States, and resident oithe city of New York,

and State of New York, have invented certain new and useful Improvemeius in Internal-Combustion Engines, of which the following is a specification.

One of the desirable features in high-speed engines is a simple and eilicicut mechanism for reversin? the engine in as a short as possible space of time. Numerous experiments have been made in solving this problem, most of which were dciined to retaining the unidirectional rotation of the driving ele- Inents, while providing devices for-reversing the rotation of the driven elements, requiring, of course, rather complicated mechanical arrangen-ren'ts, which in the inoin'ent oi oper ation Were subjected to a tremendous strain, causing them not infrequently to get out of order and, therefore, seriously to interfere with the reliable Working of the entire engine.

It is the object of the present invention to utilize a device, otherwise well known in the art as such, in an improved and modified form, which seems to represent. the most simple solution of a problem, which hitherto has been thought to be one of the most com-- This solution consistsin the application to said use in a gas engine of the combustion type, of a inultiple way valve, capable of suitably connecting the usual coinbustion chamber take-inland exhaust either '35 to the mixing chamber or to the open air and thereby reversing the function and operation of the said take-in a nd exhaust. in addition to this feature,-the new multiple-way valve is also provided with a passage or by-pass.

capable of directly interconnecting the take in to the exhaust of the combustion chamher and causing therebyn cessation of the explosions and, consequently, a gradual slowing down of the engine, which etl'ect may be lama-deuse of in restarting the engine and re- Versing its o eration by still further operating tlie'mu tiplevalve, so that connections with the inlet and outlet are reversed, as

' well as the direction of rotation of the entire engine.

ltis obvious, of course, that in order to revcrse the direction of rotation of the engine,

in the county of New York it is necessary to advance or reset the sparkplug in the proper direction.

The new device is applicable to }.)o \'crengines of any suitable type, in which case the inlet and outlet take the place of thetako-in and exhaust cl an explosive engine. The illustratioi'is, shown in the accompany inn drawings, representative of one form of the present invention, and Figure l illustrates a perspective side view of the entire engine, having embodied therein the new multiplc-valve, while Figs. 2, 3 and l illustrate vertical cross-sections of the valve in diilcrent positions, and Fig. 5 a vertical 61 05msection in a plane at right angles to the plane of the sections shown in Figs. 2, 3 and 4.

The perspective elevation, shown in the drawing, indicates at 1 the usual cylinder of an engine of the iour-cycle combustiontypc, supported on a suitable base. i

2 is the piston connected by means of a piston-rod 3 to the crank l of the driving, shaft 5. i 6 is the. combustion-chambcr, having an inlet 'or take-in 7, capable of being closed by a valve 8, which is operated by means of the valve-rod 9 and the roller 10 from the valvecam 11, keyed to the valve-shaft 12, driven by means of intermcshing gears-13 and 14 from the driving shaft 5.

'An air-valve 15 operated by means of the-valve-rod 16 and the roller 17 from the valvccam 18 on the shaft 12, is located in an air-pipe, connecting an air tank or container to the combustion chamber. The check valve 19 prevents the return of the compressed mixture of gas and air from the combustion chamber.

An outlet or exhaust 2O 01 the combustion chamber 6 is connected by means oi suitable pipes to a muffler or the open air. It is capable of being closed by a valve 21, operated through t'VulVLflOd 22 and a roller 23 iron'i a valve-ca1n E l. An igniting device or spark plug 25 is operated by a connecting rod 26 and roller 27 from a cam 28 on the shaft 12.

The take-in 7 and the exhaust '20 are connected to pipes 29 and 30, the continuation of these pipes are shown at 31 and 32, and the connection between the pipes isbroughi about by a multiple-valve nu-zchanism. This inechanisnicomprises a casing 33, contain ing a valve-body 34, rotatable on a shaft 35 by means of a lever 36. The valve-body 34 is provided with a set of assages or paths, capable of interchangeably connecting the to the mixing chamber and the open air, re-

spectively, either by" straight or by crossconnect1on,orby interconnection; For this purpose the" valvebody 34 contains a set i of two passages l'e'ad-ing'in a straight line at right angles to the axis of the valve-body,

so that 1pissage '37 may directlyand n a stralght e connect pipe 30 to pipe'32, and passage 38-1nay connect pipe 29t0 pipe--31;

' A second set of crosseconnections is capable of making the. following connections H-By means of-passage39, a connection between the pipe 29 and 32, and by means of the pas- .device, represented by the air-Va ve 15 and compressed chamber by .cam 18, while at any other cycle of rotation this valve wi a container of compressed air, not shown in the drawing, will be eflicient in two different ways, In the first Way, as a selistarting de-- vice for the engine, in-which case it is obvious that in an engine of the four cylindertype, only one of the cylinders of the engine wil be in condition to receive a air passing into the combustion opening a hand operated valve, leading to the compressed aircontainer, This will start the engine, and as compressed air is supplied to each of the other cylinders until an ignition takes place in their com-- bustion-chambers, the engine will finally-be brought to its vfull operation. The second-function of they compressed air supply is, to act as a substitute for missed explosions, in which case it takes the place of the explosive mixture after ignition and causes an additional impulse to the operating piston. It is obvious, of course, that the pressure on the tank side of the check valve 19 must always be greater than the one on the combustion-chamber side of this valve. As this valve is constructed to open toward the combustion chamber, air can be admittedionly when the valve 15 has been opened through the operation of the valve- 1period of the 1 be closed.- The use of the multi le-way valve in reversing the direction o rotation of theengine must'be preceeded by first cutting out the ignition device and closing the hand operated valve of the compressed air container, the lever 36 is then set so as to bring the lay-pass 41 in, operation, whereby the ally is ressed air charge of explosive 'mixture,- drawn in through the acting through andpassed 05 by the by-pass 41 to the combustion-chamber. spark plug 0 take-in. 7, is simply communicated 1 the acting exhaust 20, and led again into When now the erating' cam and the com pressed-air va ve operating cam is properly to cross-connect the pipes 29 and 32 and the pipes 30 and 31,- as shown in Fig' 4, the hand operated air-valve leading to the air tank is opened again,

becomes now while" the exhaust 20- becomes, the acting takein, the operation of the valve 15 remains the same, the igniting device 25.
