GAS OR INTERNAL-COMBUSTI-ON ENGINE GOVRNOR.

SPIEGIFIGATIQN forming part of Letters Patent No. 757,311, dated April 12, 1904:.`

Application filed September 8, 1903. Serial No. 172,205. (No model.)

To a/ZZ whom it may concern:

Be it known that I, PETER JENNEss, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new `and useful Improvement in Gras or Internal-Combustion Engine Governors, of which the'following is a specification.

My invention consists of a novel construction of a gas or internal-combustion engine governor, which is especially adapted to be used in connection With engines employed in automobiles; and it consists in the novel construction of mechanism whereby the supply of air and gas to the engine-cylinders is auto'- matically regulated with great eXactness, pro-l vision being also made for readily adjusting the apparatus by the operator according to requirements. r

To the above ends my invention consists of the novel featuresof construction hereinafter described, and pointed out in the claims.

Figure 1 represents a plan or diagrammatic View of a gas or internal-'combustion engine governor embodying my invention. Fig. 2 represents a plan View, partly in section, of a portion Vof the apparatus seen in Fig. 1, show? ing the valve in partly-open position.

' Similar numerals of reference indicate cor-` responding parts in the figures.

Referring to the drawings, 1 designates a cam-shaft, which is mounted in suitable bearings and provided with the gear 2, which is adapted to mesh with the`pinion 3, which is mounted on the engine or crank shaft 4, which is operated by the gas or internal-combustion engine or engines 5, it being of course understood that the engine or crank shaft 4 runs twice as fast as the cam-shaft 1, which operates the engine-valves in the usual manner.

6 designates lugs on the gear 2, upon which are pivotally mounted the bell-cranks 7, each of which have the pins 8, which engage the groove 9'on opposite sides of the sleeve 12, which is splined to the shaft 1, said bellcranks or elbow-levers 7 being provided with the balls 10, which are held in their proper relative position by means of the spring 11.

A13 designates a spiral contact-on the sleeve 12V for advancing the spark, said sleeve being also provided with agroove to t the ring 14,

which is pivotally connected to the bell-crank 15, which is fulcrumed at the point 16.

17 designates a rod leading from an arm of the bell-crank'l to the arm 18 of the bellcrank 19, which has the arm 20, to which one end of the link 21 is connected, the opposite end of said link being connected to the arm I22, which operates the throttle 23, which controls the discharge of the gas from the commingling-chamber 24 through the outlet 25 to the engine-cylinders. pivoted `at the point 26 to the arm or lever27, which isfulcrumed at the point ,'28, said arm 27 having connected thereto the rod 29, which is operated by any suitable means.A

30 designates the float or gaSOlene-chamber ofthe carbureter 31; but as these parts form no part of the present invention per ,se I have deemed it unnecessary to describe the same in detail. i n

32 designates the'contact-strip employed, the function of which will be evident.

' I have also deemed it unnecessary to show or describe .the wires or other connections whereby the ignition is effected, since the con struction of the same will be familiar to those skilled in this art;

The bell-crank 19 isl The operation is as follows: As will beap'- parent to those skilled in this art, the governor comprises the elbowlevers 7 and the ballsv 10 and operates the sleeve 12,. having the spiral contact 13v thereon for advancing the' spark, and by means of the ring 14 and its adjuncts the bell-crank l5 is operated to the desired extent, said bell-crank being connected to the throttle or air valve 23 by means of the link or connecting-rod 17, the bell-crank 19, and the rod or link 21, as has already been eX- plained. It will be apparent that the throttie-gate or air-valve 23 closes or tends to close as the spark is advanced by the governor, according to the position of the arm or lever 27, on which bell-crank 19 is pivoted, said lever 27 being itself pivoted at the point 28, as has been explained, it being further apparent that the position of the pivot of the bell-crank 19 is readily controlled by means of the rod .29, which leads to any desired point and may It will be apparent from the foregoing that by my invention the number of parts is reduced to a minimum and the construction greatly simplified, so that but a single throttle is necessary for both governing the charge admitted to the cylinders and for admitting more or less gas by independent means at the will of the operator.` It will further be apparent that the spark is automatically retarded whenever the motor is stopped, it being immaterial at what position the independent controlling device may be set.

It will be apparent that changes may be made by those skilled in the art in the manner of assembling and constructing the above parts, and I do not, therefore, desire to be limited in every instance to the exact construction I have herein shown and described.

. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character named, a carbureter, a throttle-valve, a governor, connections between said governor and throttle, a bell-crank lever which forms a part of. said connections, a pivoted arm carrying the fulcrum of the bell-crank lever, and hand-controlled means for moving said arm and thereby the throttle, whereby but a single throttlevalve is employed for vboth governing the charge admitted to the engine-cylinder and for admitting more or less gas independently at the Will of the operator.

2. In a device of the character named, a cam-shaft, a sleeve splined thereupon for longitudinal movement, a spiral contact on said sleeve, a .governor adapted to actuate said sleeve, a carbureter, a throttle-valve, connections between said governor and throttle,l a bell-crank lever which forms a part of said connections, a pivoted arm carrying the fulcrum of the bell-crank lever, and hand-controlled means for moving said arm and thereby the throttle, whereby but a single throttlevalve is employed for both governing the charge admitted to the engine-cylinder and for admitting more or less gas independently at the will of the operator.

3. In a device of the character named, a governor, a carbureter, a sleeve, connections between said governor and sleeve for moving the latter, a bell-crank actuated by the movement of said sleeve, a second bell-crank, a rod connecting said bell-cranks, a lever or arm pivoted to a fixed point, said last-mentioned bell-crank being pivoted to said lever, means for adjusting the position of said lever, a throttle-valve for said carbureter and connections intermediate said last-mentioned bellcrank and said throttle-valve.

4. In a device of the character named, a longitudinally-movable sleeve, a spiral contact thereon, a cooperating contact, a groove in saidV sleeve, a' governor adapted to move said sleeve longitudinally, a ring in engagement with said groove, a bell-crank pivoted to a iiXed point and connected Vto said ring, a second bell-crank, a rod common to said bellcranks, an arm or lever upon which said second bell-crank is pivotally mounted, said arm being pivoted to a xed point, a carbureter, a throttle-valve for said carbureter, connections intermediate said second bell-crank and valve, and means for adjusting the position of said second bell-crank.

5. In device of the character named, a governor, a longitudinally-movable sleeve having a groove therein, connections from said governor engaging said groove, a spiral contact 13 on said sleeve, a cooperating contact, a ring 14 engaging a second groove in said sleeve, a bell-crank 15 connected to said ring, said bell-crank being fulcrumed at a xed point, a second bell-crank 19, a rod 17 connecting said bell-cranks, a lever 27 fulcrumed at a Xed point 28, said bell-crank 19 being pivoted to said lever, a carbureter having a commingling-chamber 24 therein, ar valve 23 controlling the discharge of gas from said commingling-chamber, an arm 22 for actuating said valve, a rod 21 intermediate said arm and the bell-crank lever 19, and a rod 29 for adjusting simultaneously the position of said lever 27 and said bell-crank 19.
