Abstract
Abstract Lever-amplified actuating means for valves and other devices which may be used to replace heretofore employed hydraulic jacks capable of transforming a small force traveling a great distance into a large force being motivated over a small distance, and where such amplifying ratios exceed 5 to 1; the mechanical amplifying means consisting of two upper ball bearings displaced radially down by a piston or diaphragm plate which in turn causes a co-sinusoidal, small-distance displacement of a lower pair of ball bearings.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
177 words
Lever-amplified actuating means for valves and other devices comprising: a. one pair of toggle elements mounted in spaced relationship within a housing having a central opening, each of said toggle elements pivotably supported by shaft means which are suitably retained within a said housing; b. each of said toggle elements comprising at least one upper bearing suitably supported essentially level to said shaft means, and at least one lower bearing suitably rotatably supported below said shaft means; c. displacement means mounted within the lower portion of said central opening of said housing and being engaged to said lower bearings; d. plate means mounted within the upper portion of the housing opening having a flat lower surface being subjected to rolling motion of the upper bearings and capable of engaging and displacing said upper bearings down and thereby pivoting said pair of toggle elements around said shaft means, said pivoting motion further causing said lower bearings to extend their co-sinusidal distance with respect to the supporting shaft means and thereby causing a downward motion of said displacement means.
Claim 2
Dependent Claim
177 words
Lever-amplified actuating means for valves and other devices comprising: a. one pair of toggle elements mounted in spaced relationship within a housing having a central opening, each of said toggle elements pivotably supported by shaft means which are suitably retained within a said housing; b. each of said toggle elements comprising at least one upper bearing suitably supported essentially level to said shaft means, and at least one lower bearing suitably rotatably supported below said shaft means; c. displacement means mounted within the lower portion of said central opening of said housing and being engaged to said lower bearings; d. plate means mounted within the upper portion of the housing opening having a flat lower surface being subjected to rolling motion of the upper bearings and capable of engaging and displacing said upper bearings down and thereby pivoting said pair of toggle elements around said shaft means, said pivoting motion further causing said lower bearings to extend their co-sinusidal distance with respect to the supporting shaft means and thereby causing a downward motion of said displacement means.
Claim 3
Dependent Claim
50 words
Lever-amplified actuating means for valves and other devices as described in claim 1, having retaining means to close up the upper portion of the central opening of said housing and wherein said retaining means encloses at least one coiled spring capable of exerting a downward force onto said plate means.
Claim 4
Dependent Claim
30 words
Lever-amplified actuating means for valves and other devices as described in claim 1, where said displacement means is cooperating with closure means capable of opening and closing a valve orifice.
Claim 5
Dependent Claim
37 words
Lever-amplified actuating means for valves and other devices as described in claim 3, when said displacement means is arranged to have an adjustable portion capable of changing the distance between said lower bearings and said valve orifice.
