EDWARD A. ZOLLE, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO MOORE CABVING MACHINE COMPANY, OF MINNEAPOLIS, MINNESOTA, A CORPORATION OF MINNE- SOTA.

REGULATOR FOR MULTIPLE-CYLINDER ENGINES.

To all whom it may concern:

Be it known that I, EDWARD A. ZOLLE, a citizen of the United States, and resident of Minneapolis, in the county of l-Iennepin and State of Minnesota, have invented certain Improvements in Regulators for Multiple- Cylinder Engines, of which the following is a specification.

This invention relates particularly to improvements in the multiple cylinder engine shown and described in Letters Patent No. 880,958, issued iWIarch 3rd, 1968, to Frank X. Bachle and John C. L. Krebs. In that patent an engine is described having two or more cylinders, and in the case of a twocylinder engine the charge is pumped into the combustion end of each cylinder by the piston of the other cylinder, and in the case of a three or more cylinder engine the charge is pumped into the combustion end of each cylinder by the pistons of two or more cylinders of the series.

In using this engine I find it advantageous to regulate the amount of the charge that is pumped into the combustion end of each cylinder, and I preferably, at the same time, regulate the supply of gas from the carbureter. In this way I am enabled to slow down the engine and at the same time have it run smoothly and evenly without missing any explosions, and economizing materially in the cost of fuel.

The invention consists generally in the constructions and combinations hereinafter described and particularly pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a vertical, longitudinal section through the distributer of an engine of the type designated and having my regulator applied thereto, Fig. 2 is a vertical section on line 22 of Fig. 1, Fig. 3 is a detail section of the regulator, Fig. t is an outline view showing means for simultaneously operating the regulator and the valve of the carbureter.

In the drawings, 1, 2, 3 and 4 represent the cylinders of an engine embodying my improvement. Each of the pistons is marked 5 and the enlargements at the lower ends are marked 5. A rotating distributer or rotary valve 6 is arranged in a housing or valve casing 7, and this rotary valve is provided with ports arranged to register with the ports of the cylinder. These parts Specification of Letters Patent.

of the engine are all substantially as shown and described in said Patent No. 880,958.

I provide in connection with the rotary valve 6, a valve or regulator, which permits me to cut out at will the passage of the charge to the combustion end of the cylinder from all but one of said cylinders. When this cut-oft is closed each cylinder instead of receiving in its combustion chamber a charge that is pumped into it by the pistons of two or more cylinders of the series, will receive only the charge pumped into it by one of the cylinders of the series. For this purpose I provide a suitable valve 9 located preferably near the center of the rotary valve 6. As I have shown this device in the present drawing, a sleeve 8 forming a valve seat is located at or near the central point longitudinal of the rotary valve or distributer 6. The valve 9 is arranged to engage the seat 8 and it is provided with a stem 10 that passes through a suitable stufiing box 13 at the end of the distributing chamber. A collar 12 is arranged upon the valve stem 10 and a suitable spring 11 surrounds the valve stem 10, and has one end bearing upon the sleeve Sand the other against the collar 12 on the valve stem 10. Vfith this construction the spring tends to hold the valve 9 at all times against the seat. A suitable operating lever 14 is arranged in position to engage the end of the valve stem 10. Any suitable means may be employed for operating the lever 14.

In running the engine ordinarily the lever let will be moved into position to engage the valve stem 10 and force the valve 9 off from the seat 8, thereby leaving a clear passage from'end to end of the rotary valve or distributer 6. v By releasing the lever lt the spring 11 will close the valve 9 upon its seat 8 and communication through the length of the rotary distributing valve will be pre vented by said valve 9. When the valve 9 is open the distribution of the charge is the same as described in said Patent No. 880,958, thatis to say, cylinder No. 1 has its charge compressed therein by the pistons of cylinders 2 and 4; cylinder No. 2 by the pistons of cylinders Nos. 1 and 3; cylinder No. 3 by the pistons of cylinders Nos. 1 and 4 and cylinder No. at by the pistonsof cylinders Nos. 2. and 3. Nhen the regulator valve 9 is closed, as shown in Fig. 1 of the drawing, the charge in cylinder No. 1 is compressed therein by the No. 2 piston, and the charge in cylinder No. 2 is compressed therein by the No. 1 piston; the charge in cylinder No. 3 is compressed therein by the No. 4: piston and the charge in cylinder No. 4 is com pressed therein by the No. 3 piston. With the regulator valve closed, as stated, each cylinder will receive only half as much gas as it will with the regulator valve open, as in the last named case each cylinder will receive the gas pumped into it by the pistons of twoof the other cylinders. This construction is exceedingly simple and is easily applied to the rotary valves or distributors of said Patent No. 880,958.

IV hen it is desired to slow down the engine the valve 9 in the rotary valve or distributor 6 is closed by releasing the lever 14 and permitting the spring 11 to bring said valve against its seat, and then each cylinder receives in its combustion chamber the gas pumped into it by only one piston, as hereinbeiore set forth.

I find this device particularly advantage ous where it is desired to run very slowly, or where it is desired to leave an engine running idle. Only one-half as much gas will be supplied to each combustion chamber when the valve is closed as will be when this engine is not provided with this valve, or as will be with this engine when the valve 9 is open.

I also find. it advantageous, in using this device, to regulate the valve of the carbureter sin'iultaneously with the opening or closing of the regulator valve 9. In Fig. 4. of the drawings I have shown the outline of a carburetor connected to the distributing chamber of the engine, so as to furnish gas for the cylinders. This carbureter is provided with a rod 15 which extends to a pedal or lever 16 in position to be under the control of the operator of the engine. A rod 17 also extends from the lever 14 to the same pedal or operating lever. YVith this arrangement, when I close the valve 9, through the lever 14, I simultaneously adjust the carburetor so as to cut down the supply of gas to the engine, and when I open the regulator valve 9 I open the carbureter valve also, and increase the supply of gas to the engine. By this means I materially economize in the use of fuel for the engine. hen I am running the engine slowly and do not need much power I cut down the supply of fuel and at the same time secure an even running of the engine with regular explosions in the cylinders. I find that the engine does not miss any explosions and that with this device a two-cycle engine can be throttled with much better results than have here tofore been obtained. \Vhen the regulator valve is closed the space that is to be filled by the gas driven out of a cylinder by the enlargement on its piston, is very much reduced. Hence, a greater compression of the charge can be obtained than would be possible by throttling the engine through reducing the delivery oi gas at the carbureter alone.

While I prefer to use in conjunction with the regulating valve the means described tor regulating the supply of gas from the carbureter, I do not limit myself to the use of this last named feature, as important advantages will result t'rom the use of the regulating valve alone.

I do not limit myself to the details of con struction, as the same may be varied in many particulars without departing from my invention.
