Abstract: A device for controllably restricting flow through a resilient tube including a block and a pair of generally J-shaped leg members pivotally mounted to the block. The leg members, when pivoted together, together provide a tube support surface. The block is formed with a bore in which there is a rotatable internally threaded sleeve. A jaw member having a threaded shaft is threadedly mated to the sleeve and a knob is fixedly secured to the sleeve for rotation therewith. Accordingly, rotation of the knob moves the jaw member toward and away from the tube support surface to provide desired compression to a length of resilient tubing captured between the jaw and the tube support surface. By pivoting the leg members away from each other, space is provided for installation of the flow restriction device at any desired point along the length of the tubing.

Abstract: A lockout device is designed for use with a valve having a pair of spaced apart, generally opposed abutment surfaces, with at least one of the abutment surfaces being shiftable relative to the other in such manner that the spacing between the surfaces decreases when the valve is actuated from a select condition. The lockout device includes a pair of generally oppositely facing engagement faces positionable between the abutment surfaces, and the device is adjustable so that the user may vary the distance between the engagement faces. In this respect, the lockout device may be disposed between the abutment surfaces and the engagement faces may be brought into secure, positive engagement with the abutment surfaces when the valve is in the select condition. This will prevent movement of the at least one abutment surface toward the other, and thereby prevent actuation of the valve.

Abstract: A freeze protection plug has latching balls engageable bayonet-fashion with grooves in a fitting. The balls are normally held in engagement with the grooves by a cam, but move inward to release the plug from the fitting when the cam is moved by a thermal actuator carried by the plug. The balls are retained in tapered openings in the wall of the plug to reduce jamming. Helical ramps in the grooves permit the use of a strong, reliable plug ejecting spring, and make manual insertion of the plug easy. Insertion is aided by the ribs of a plastic cap, which facilitate manual grasping and rotation of the plug. A paint shield ring prevents failures resulting from paint bridges adhering both to the plug and to the fitting. A unitary molded lanyard with two oval loops prevents loss of the plug. The seal on the plug is located on the liquid system side of the latching balls and isolates moving parts from the liquid system, and is of small diameter.

Abstract: A new FAUCET SAFETY STOP for preventing a user, especially a child, from turning a water faucet beyond a predetermined point.

Abstract: A removable interlock spacer is disposed between the rear face of a control knob and the face of a control panel of a cooking device, such as a stove or a barbecue grill, to prevent the control knob from being pushed in far enough to activate the associated cooking element(s). The push-in-and-turn type switches used in such devices require that the control knob be pushed in before the switch can be moved from its off position. The interlock spacer is of sufficient thickness to prevent the control knob from being pushed in far enough to allow the switch to be moved from its off position. Thus, the cooking element cannot be activated with the interlock spacer in position. When the cooking device is to be used, the interlock spacer may be removed and the switch will operate normally. Thereafter, when cooking is complete, the interlock spacer is re-installed so that young children and the like will not inadvertently create a hazard to themselves and others.
