Description

Aug. 27, 1963 H. J. OLSON 3,101,670
FLUID-ACTUATED APPARATUS TO CONTROL MOTOR SPEED Filed June 8, 1961 INVENTOR.
1 3,101,670 FLUID-ACTUATED APPARATUS T CONTROL MOTOR SPEED Harold J. Olson, Broadway, Raynham, Mass. Filed June 8, 1961, Ser. No. 115,810 5 Claimsr (Cl. 10317) This invention relates to apparatus, actuated by a fluid, whereby the speed of a motor can be controlled.
One object of my invention is to provide such apparatus having vacuum-creating means operably connected to a vacuum-operated, control member and throttle-control mechanism, and having restricting means in a vacuum-conduit line whereby the vacuum therein can be controlled to a fine degree.
Another object is to provide such apparatus having said restricting means, with a vacuum breaker, the restricting means being so set that it has at least a minimum opening that is sufflcient to permit establishment of a vacuum that can overcome the effect of air entering said line through the vacuum breaker.
A further object is to provide parts that form said apparatus and to so op e'rably arrange them that the installation of my apparatus in an automobile truck power mechanism, or the like, is relatively simple and inexpensive.
The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative arrangement of parts such as is disclosed by the drawing. The nature of the invention is such as to render it susceptible to various changes and modifications, and, therefore, I am not tobe limited to the construction disclosed by the drawing nor to the particular parts described in the specification; but am entitled to all such changes therefrom as fall within the scope of my claims. 1
In the drawing:
FIG. 1 is a diagrammatic view showing my apparatus operably connected to a fluid-actuated device that operates without an electric circuit.
' As illustrated, my throttle control apparatus has a fluid-actuated, magnet device 12 responsive to fluid flow having a passage therein and that is operably connected to a fluid discharge conduit 14 communicating with a pump 15 and such as disclosed in my Patent No. 2,842,150, dated July 8, 1958. Communicating with said device 12 is a conduit 16 that communicates with the usual vacuum-creating means having a manifold 18 of an internal combustion motor of an auto truck.
In order to control the degree of vacuum in said conduit 16 I provide a vacuum restricting valve 20 therefor having the usual control mechanism 21 and having a lower opening 22 on the manifold side thereof which opening is closed when the valve is shut off. Said valve 29 also has an upper opening 24, on the device side thereof. This restricting valve 26 is used to control the speed of the pumping operation, as later explained.
A conduit 26 communicates with a vacuum breaker 28 which permits sufficient air to pass into said conduit 26 to break the vacuum when the pumping operation ceases thus relieving pull on a control diaphragm 36 and an arm 4-2 later described. This vacuum breaker 28 has a filter 30 and an open dust cover 32. Said conduit 26 continues preferably as a flexible hose 26a that communicates with a vacuum-operated member such as a control diaphragm 36 that is mounted on a bracket 38 and to which throttle control mechanism 4% is operably attached, having an anm 42 extending therefrom that is attached to a bead chain 4- 3. The latter is attached to a connector 46 to which is connected a throttle rod 48 extending to a carburetor 50 that governs the supply of asoline or other fuel to an internal combustion motor.
When oil, 'ior instance, is pumped by the motor, from a supply tank to a place of use, such as a heating apparatus storage tank, the fluid-actuated device 1'2 is actuated to thereby establish communication through the passage in the latter, through said conduits 16 and 26 and said manifold 18. Thus said vacuum operated member 36 is actuated and thereby said throttle controlmechanism 46. This automatically speeds up the motor which accelerates the pumping operation.
Inasmuch as the number of gallons per minute that can valve 20 in said conduit 26 which can vary the degree of vacuum in the latter.
Since my apparatus is used by those unfamiliar with the details of its mode of operation, said restricting valve 24) is preferably so regulated as to always be open suificien-t-ly so that the vacuum established in the passages in my apparatus will be sufiicient to overcome the effect of said vacuum breaker. This makes certain that the throttle control mechanism can be actuated to some degree when my apparatus becomes operative.
