- Application filed December 2,

-Be it known that I, GOTTLIEB KELLER, a Switzerland, and a resident of the city of New York, borough of'Manhattan, in the county and State of New York, have invented a new and Improved Motor, of which the] following is a full, clear, and exact description.

The object of the invention is to provide a new and improved motor or explosion en.- gine of'the two-cycle type arranged to utilize the motive agent to the fullest advantage by giving continuous impulses in proper rotapistons connected with the main shaft, to insure a steady and uniform running of the engine and hence permit the use of the motor on automobiles and the like.

The invention consists of novel features and. parts and combinations of the same which will be more fully described hereinafter and then pointed out in the claim.

A practical embodiment of the invention is represented in the accompanying drawngs forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of .the improvement; Fig. 2 is a plan view of the same, parts being in section; Fi 3 is an enlarged sectional side elevation of the valve for controlling the admission and exhaust of the motive agent;'Fig. 4 is a sectional plan view of the same, on the line 4-4 of Fig. 3; Fig. 5 is a similar view of the same, on the line 5-5 of Fig. 3; Figs. 6 and 7 are similar views, showing the valve plug in aand Fig. 8 is a cross secon the line 8-8 of Fig. 3. motor as illustrated in the drawin s is-preferabl provided with two pairs 0 cylinders A, and A A and in each of the cylinders is mounted to reciprocate a pistonB connected by a pitman C shut-off position; tion of the valve,

The improved with a crank arm D on the main drivingshaft E, the crank arms D for the pistons 111 the cylinders A and A being arranged diametrically opposite each other, and the crank arms D for the pistons in the cylinders A and A being likewise arranged diametrically and at right angles to the crank arms D for the pistons of the cylinders A and A; thus the several crank arms stand in quarter positions relative to each other,

as will be readily understood by reference to- Fig. 1. The motive agent to and from .the

pairs of cylinders A, A A A is controlled by valves F, each of whichis provided with a'rockingconical valve plug F,

provided at 'its stem F? with an arm Goonn'ected by a link G, with a bell crank lever G connected with theeccentric rod G of an eccentric Gr secured on the-main shaft E. Thus, by the arrangement described each valve plug F is turned in-unison with the movement of the pistons B,"as the latter are connected with and impart rotary. motion to the main shaft E. I

Each valve plugF provided with two chambers or compartments F and ,F, of

which the chamber F is the inlet chamber and the chamber F is the exhaust chamber. The inlet chamber F is provided, in its side wall, with a port. a at all times in register e H connectedby a pipe e source of motive agent H" being provided with with a supply i H with a suit b supply, the valve a suitable valve H of the motive agent to the pipe H. Each of the inlet chambers F is also provided with an admission port b ada ted to alternately register with ports 0 an 0 leading to the outer ends of the cylinders A,'A or A A so as to alternately admit motive agent from to the corresponding cylin- A In each of the 'ports 0 and c is arranged a check valve I to prevent accidental back firing. The exhaust chamber F in each valve plug F is provided in its side wall, with two portsd and (1 adapted to register alternately with exhaust ports e and 6 leading from the cylinders A and A or A and A The bottom of each chamber F connects with an exhaust pipe H for carryi off the exhaust to a suitable place of disc arge, the ipe H containing a valve 4 connected with the valve H so that both valves H and H can be opened, and closed simultaneously by the operator. Each of the cylinders A, A and A A is provided with a sparkingl plug J the chamber F or other device for igniting the c arge in the outer end of the corresponding cylinder.

The operation is as follows: When the several part-s are in the position as illustrated in Figs. 1, 2, 3, 4 and 5, then the valve plug F of the valve F for the cylinders A and A connects, by'its ort b, with the port 0 opening into the cylin er A, while the port 0 for the cylinder A is cut off. The cylinder A, however, is connected by the port 0 with the port d (see Fig. 5) opening into for controlling the flowthe exhaust chamber Ft. Now, the motive agent entering the chamber F of the valve nitin F for the cylinders A and A passes into the cylinder A, to be ignited therein by-the igdevice J so as to ive an impulse to therpiston B in the cylin ex A to rotate the shaft E; At the same time the piston Bin the cylinder A is on the return stroke, so

that the gases of the previous explosion pass byway ofthe ports a and d into the chamber F and through the pi e H -to a suitable place of discharge. Whi e this takes place inithe cylinders A and A, the'valve F for the cylinders A and A is about to connect ."with the cylinder ports, to'allow gas to pass into one cylinder, while the products of combustion from the previous explosion in'the other'cylinder are discharged as soon as the piston-is on'itsreturn stroke. It is'underjstood that when the pistons B in the cylinderssA andA are at or near the ends of -:"their. strokes, then} the pistons in the cylin-' contained therein.

' consequently {der's'fA and A are inmiddle position, or

is ignited, as the c eck valve I will close and prevent back firing through the ports a and into the chamber F of the with the shaft havi cranks being. arrange at right angles to in the cylinders,r0ds connecting'the p and thecranks, the 'rods'connectingt e'l.pis+

tons of each pair with oppositelyprojecting' valve plug I It is' further understood that the charge, passing into a cylinder may have been previously compressed by a suitable pump ,or jo'ther means,so that ,further compression'in the cylinder previous to igniting the charge'is not necessary. I

Having thus described'my nvention, I

claim as new and desire to secure byLetters Patent:-' g I I In an explosionv engine, "the comb nation, four cranks, said each other, of two pair of cylinders,- pistons cranks, a, controlling, valve for controlling the admission and'exhau's't' for each 'pair' j'o'f cylinders, said valveco'mprising a valve plu provided; with an inlet chamber conne'te with thegas supply, anda port'fadapted to register alternately with the admission ports forthe cylinders, said plug also having anistons exhaust chamber connected'with an exhaust,

and havin ports adapted to alternately connectwith t e exhaust ports for the cylinders, and a check valve in eachlof the, admission ports for-the saidflcylinders'.

In testimony whereof -I have signed my name to this specification in the presence of two subscribing witnesses.
