GOVERNOR ATTACHMENT FOR TRACTORS. FILED NOV-8,1921.
Patented lane ll, lti llth GOVERNOR ATTACHIVIENT FUR TRACTORS.
Application filed November a, 1921.
To all whom it may concern:
Be it known that l, HERMAN ESSMANN, a citizen of the United States, residing near Pender, in the county of Wayne and State of Nebraska, have invented certain new and useful Improvements in Governor Attach ments for Tractors, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to a governor attachment for tractors and it has for its object to provide an improved arrangement and correlation of parts whereby a well known type of centrifugal goveii'nor may be brought into operative relation with the throttle valve of'the engine of a well known tractor at a minimum cost and with very little change in existing parts of the mechanisln.
l urtherobjects and advantages of the invention will be set forth in the detailed description which follows.
in the accompanying drawing:
Fig. 1 is a plan view of the engine of the tractor showing the relative arrangement of the parts of the governor mechanism;
Fig. 2 is a side elevation; and
Fig. 3 a detail view of a pulley associated with the magneto shaft of the engine.
Like numerals designate corresponding parts throughout the several figures of the drawing.
. in the drawing 5 designates the chassis and 6 the engine of a well known tractor. The passage of the explosive mixture from the carburetor 7 to the intake manifold 8 is controlled by a throttle valve indicated at 9.
According to the present invention this throttle valve is connected to a rod 10 which leads to the operating arm 11 of a well known type of centrifugal governor, such as is indicated at 12. This governor is driven by a pulley 13 and belt 14L from a pulley 15 which is mounted upon the magneto shaft- 16 of the engine, the magneto being indicated at 1?. The pulley 15 is provided with a hub 18 which. is pinned at 19 to the mag neto shaft 16 and the arrangement such that a very simple, inexpensive and direct Serial No. 513,861.
drive is provided between the magneto shaft and the governor. Upon speeding up of the governor the balls 20 spread apart and thrust downwardly upon the rod 21 which rocks the bell-crank lever 22 of which the operating arm 11 constitutes a part and this in turn acting through the rod 10 actuates the throttle valve 9 to cut off some of the fuel supply to the engine.
I am aware of the fact that it has heretofore been proposed to apply governors to tractors of varying types, but so far as I am aware I am the first to employ a known commercial type of governor of the character of that indicated and to associate it with p the existing mechanism of the tractor in the simple, inexpensive and direct way herein shown.
Having described my invention what I claim is:
The combination with a tractor and its longitudinally disposed engine having a magneto shaft extending longitudinally along one side of said engine and having a (fittl'lilllfi'tfil on the other side of said engine of a governor of the vertical centriii'fugal type comprising a vertically movable rod, a bell crank lever actuated by said rod and directly engaged with the lower end of said rod a rearwardly extending rod forming a direct connection between one arm of said bell crank lever and the throttle valve of the engine, a rotative sleeve, a centrifugal mech anism carried by said sleeve and acting upon said rod, a horizontal shaft, beveled gearing between the horizontal shaft and said sleeve, said horizontal shaft projecting forwardly of the engine and in pa ZtllGliSill with the magneto shaft, upon the opposite side of the governor from the bell-crank lever, a pulley carried by the horizontal shaft, a pulley upon the magneto shaft forwardly of the engine and a belt extending across the front of the engine and engaging said pulley.
In testimony whereof I hereunto my signature.
