CONTROL DEVICE FUR INTERNAL-COMBUSTZQL ENGINES.

Application filed November 30, 1923, fie

according to the varyi the motor.

ng speed or load of Hitherto, such adjustment only could be effected manually, that is to say the motor attendant had to watch as accurately as possible the moments when adjustment was to take place, and to endeavour to bring about the most suitable for the time being.

degree of adjustment Even when performed with a certain degree of skill, such adjustment must of course always be relatively inaccurate. The arrangement, which at any rate has necessitated constant presence and attention on the part of the motor attendant, could be applied without convenience in boat motors where,

too much inas a rule,

the motor attendant always stays beside the motor, but in stationar y motors, where this is not the case, the arrangement could not be made use of to any ll ow, for its ob ect to bring adjustment of the fuel ment being effected by greater extent.

therefore, the present invention has about an automatic valve, such ad ustthe motor itself, and

the arrangement provided according to the invention is essentially fact that the fuel valve to be adjusted for the distinguished by the of the motor adapted control is connected with the motor or any part therewith in such a manner that a change in the speed or load of the motor of the fuel valve, action is altered.

results in the adjustment ereby the spreading In applying the invention, a centrifugal governor driven by the motor is preferably made use or, and the annexed drawing illustrates by way of diagrammatic representation one embodiment of the invention provided with a governor of the said type.

Fig. 1 shows the arrangement viewed from the side, right angles to Fig. 1.

and Fig. 2 is an elevation taken at According to the drawing, a common centrifugal governor 1 is used,

the spindle 2 of said governor being driven directly from the motor. The mounted in the spindle governor weights 3, with a sleeve 4 adapte member 12,

slidably 2 and actuated by the is rigidly connected (1 to be displaced on rial No. 6*YZ,815, and in Sweden October 22, 1.923.

the spindle :2, said sleeve a being preferably shaped as a double cone and having two rollers 5 bearing on the conical parts thereof, said rollers being journalled in a sleeve 6 forming a cross ournalled piece on a shaft 7, which is as at 8, and carries a worm 9 cooperating with a worm wheel 10 on the spindle 11 of the fuel valve.

ll is rotatable i The spindle n known manner for the purpose of effecting the control in question.

When the governor weights are deflected so as to displace the sleeve l, the latter with its one conical part actuates the one roller 5 so that it will be moved from the spindle 2,

while at the same time the other roller following its corresponding cone is approached to the spindle. This will result in turning of the sleeve 6 and the shaft 7 which latter transmits the tu spindle 11 of the rning movement onto the fuel valve through themedium of the worm gear 9, 10.

The inechani al connection between the governor spindle and the spindle of the fuel valve may evidently be devised in a number of ways other than herein shown and described. The arrangement with the double conical sleeve and the cross piece 6 as described and illustrated is, however, particularly advantageous,

in that it practically eliminates all dead working between the arts, while being eminently easyoperating.

The arrangement be very sensitive will therefore be found to and quiclcacting.

What I claim as new and desire to secure by Letters Patent of the United States of America is 1. In an arrangement of the character described, a governor including a rotatable spindle,

a double conical sleeve slidably mounted upon the spindle and responsive in movement to the ported operating a rotatably supgovernor,

the

shaft, a cross piece on said shaft, and rollers upon said cross piece adapted to bear against the conical surface of said sleeve so that when the sleeve is axially displaced on the governor spindle the rotatable sha ment.

ft receives a rotary move- 2. In an arrangement of the character described, a governor including a rotatable spindle, a vertica said spindle,

spindle and oper lly slidable member within governor arms mounted on the atively connected with the member for imparting slidable movement thereto, a double conical sleeve slidably mounted on the spindle and rigidly connected with the member so as to be movable therein relative to the spindle, a rotatably supported shaft. gearing between the shaft and the part to be operated, a cross piece on said shaft, and rollers upon said cross piece adapted to bear against the conical surface of said sleeve so that when said sleeve is 10 axially displaced the rotatable shaft is operated.

In testimony whereof I affix my signature.
