Abstract
Abstract A hosecock for constricting the flow of fluid in a flexible tube is disclosed. The hosecock comprises a body which includes at least one jaw. The jaw is disposed adjacent the tubes whose flow is to be controlled by the hosecock. A plug is rotatably mounted in the body of the hosecock and a coil spring is disposed around and secured to the plug. The end section of the spring is straight and forms an arm which, along with one of the facing jaws, defines a channel for receiving the flexible tube. The plug is set in a desired angular position so as to urge the arm of the spring toward or away from the tube, thereby closing or opening the tube. The arm of the spring is adapted to be engaged by an electromagnetic operator, such as a solenoid. When the operation is activated, the arm is moved in relation to the tube, thereby controlling the fluid flow through the tube. In the preferred embodiment, the arm extends between a pair of tubes which are disposed between a pair of facing jaws and alternately constricts the fluid flow through one of them.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
A hosecock for controlling the flow of a fluid in a flexible tube, comprising: a. a body; b. a jaw supported in said body; c. arm means for defining a channel for receiving the tube, said arm means being spaced from said jaw and adapted to be displaced by an electromechanical operator, said channel being defined between said jaw and said arm means; d. a plug rotatably mounted in said body adjacent said arm means; e. spring means for urging said arm means toward said jaw to pinch said tube, said spring means being secured to said arm means and plug and disposed around and secured to said plug and being put in torsion by angular displacement of said plug; and f. means for setting said plug in a desired angular position.
Claim 2
Dependent Claim
132 words
A hosecock for controlling the flow of a fluid in a flexible tube, comprising: a. a body; b. a jaw supported in said body; c. arm means for defining a channel for receiving the tube, said arm means being spaced from said jaw and adapted to be displaced by an electromechanical operator, said channel being defined between said jaw and said arm means; d. a plug rotatably mounted in said body adjacent said arm means; e. spring means for urging said arm means toward said jaw to pinch said tube, said spring means being secured to said arm means and plug and disposed around and secured to said plug and being put in torsion by angular displacement of said plug; and f. means for setting said plug in a desired angular position.
Claim 3
Dependent Claim
139 words
A hosecock for controlling flow through two flexible tubes by alternately constricting the flow of a fluid through one of the two flexible tubes, comprising: a. a body; b. a pair of facing jaws supported in said body; c. arm means disposed between said jaws for defining a pair of apertures between said arm means and each of said jaws for receiving the two flexible tubes, said arm means adapted to be displaced by an electromechanical operator; d. a plug rotatably mounted in said body adjacent said arm means; e. spring means for urging said arm means toward one of said facing jaws secured to said arm means and disposed around and secured to said plug, said spring means being put in torsion by rotation of said plug; and f. means for securing said plug in a desired position.
Claim 4
Dependent Claim
139 words
A hosecock for controlling flow through two flexible tubes by alternately constricting the flow of a fluid through one of the two flexible tubes, comprising: a. a body; b. a pair of facing jaws supported in said body; c. arm means disposed between said jaws for defining a pair of apertures between said arm means and each of said jaws for receiving the two flexible tubes, said arm means adapted to be displaced by an electromechanical operator; d. a plug rotatably mounted in said body adjacent said arm means; e. spring means for urging said arm means toward one of said facing jaws secured to said arm means and disposed around and secured to said plug, said spring means being put in torsion by rotation of said plug; and f. means for securing said plug in a desired position.
Claim 5
Dependent Claim
29 words
A hosecock as in claim 2, wherein said means for securing said plug comprises a setscrew mounted in said body for holding said plug in the desired angular position.
Claim 6
Dependent Claim
18 words
A hosecock as in claim 3, wherein said spring means and said arm means are a single element.
Claim 7
Dependent Claim
22 words
A hosecock as in claim 4, wherein the end of said arm is bent to insure positive engagement for said electromechanical operator.
Claim 8
Dependent Claim
23 words
A hosecock as in claim 5, wherein said plug includes a groove for facilitating the adjustment of the angular position of the plug.
