Abstract
Abstract A bracket is pivotally mounted at its first end on a stationary support for rotation about a first axis. A handle is pivotally mounted on a second end of the bracket for rotation about a second axis which is disposed transversely relative to the first axis. The handle and bracket each have an extension formed thereon which is connected to respective control valve stems whereby pivotal movement of the handle about the first axis will reciprocate one of the valve stems and pivotal movement of the handle about the second axis will reciprocate the other valve stem.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
A single lever control adapted to actuate separate valves comprising a stationary support, a bracket pivotally mounted at a first end thereof on said support by first pivot means for rotation about a first axis, a handle pivotally mounted on a second end of said bracket by second pivot means for rotation about a second axis disposed transversely relative to said first axis, a first extension, adapted for attachment to said stem of said first valve, secured to said handle to extend inwardly away from said second pivot means toward said first pivot means and in the general direction of said first axis, and a second extension, adapted for attachment to said stem of said second valve, secured to said bracket to extend in the general direction of said second axis.
Claim 2
Dependent Claim
131 words
A single lever control adapted to actuate separate valves comprising a stationary support, a bracket pivotally mounted at a first end thereof on said support by first pivot means for rotation about a first axis, a handle pivotally mounted on a second end of said bracket by second pivot means for rotation about a second axis disposed transversely relative to said first axis, a first extension, adapted for attachment to said stem of said first valve, secured to said handle to extend inwardly away from said second pivot means toward said first pivot means and in the general direction of said first axis, and a second extension, adapted for attachment to said stem of said second valve, secured to said bracket to extend in the general direction of said second axis.
Claim 3
Dependent Claim
24 words
The invention of claim 1 wherein said bracket is generally U-shaped and said second extension is secured to said bracket intermediate the ends thereof.
Claim 4
Dependent Claim
31 words
The invention of claim 1 wherein said first and second axes are substantially positioned perpendicular relative to each other and are disposed in the same horizontal plane to intersect each other.
Claim 5
Dependent Claim
64 words
The invention of claim 1 further comprising first and second linkage means pivotally interconnecting said first and second extensions, respectively, with a respective one of said valve stems whereby pivotal movement of said handle about said first axis will reciprocate one of said valve stems and pivotal movement of said handle about said second axis will reciprocate the other one of said valve stems.
Claim 6
Dependent Claim
19 words
The invention of claim 4 wherein said first linkage means universally connects said first extension to said first stem.
Claim 7
Dependent Claim
15 words
The invention of claim 5 wherein said second linkage means conStitutes a pair of links.
