Abstract: A spring (304) biases a movable housing part (12, 16) away from a fixed housing part (10, 306, 156). The fixed housing part (10, 306, 156) is composed only a main housing (10), a draw tube (306) and an inlet valve housing (156). The inlet valve housing (156) is inserted into the main housing (10). The movable housing part (12, 16) is composed of a forward housing (12), which includes a trigger (14), and a nozzle (16). The main housing (10), the inlet valve housing (156) and the forward housing (12) together form a variable volume pump chamber (318). The inlet valve (184, 268) includes , a valve plug (184) which is initially connected to a sidewall portion (168) of the inlet valve housing (156) by a frangible section (196). During assembly, an axial push is imposed on the valve plug (184), to sever the frangible section (196), and then move the valve plug (184) rearwardly past stop lugs (198, 200), into a position axially between the stop lugs (198, 200) and an inlet valve seat (268).

Abstract: A dispenser for simultaneously dispensing and mixing a pair of fluid products such as chemically reactive resins, from a pair of axial adjacent front and rear chambers. A piston is mounted within each of the chambers and is moveable with respect to the hollow interior of the respective chamber for dispensing the fluid product therefrom. Telescopic movement of the rear chamber within the front chamber moves the pistons synchronously through the chambers to provide for controlled discharge of the products through a front discharge nozzle. A fixed hollow delivery tube extends through the interior of the front chamber and telescopically receives therein a post which is mounted on a rear wall of the rear chamber. The rear chamber has a relatively tight sliding fit within the front chamber so that a partial vacuum is formed within an annular space which forms between the two pistons as they move apart upon discharge of the two products to produce a "suck back" effect on product remaining in the discharge nozzle.

Abstract: A barbecue grill assembly including a main cooking chamber, a removable cooking grid positioned within the main chamber above a primary heat source, a frame for supporting the cooking grid and a drawer element connected to and supporting the frame for rollably withdrawing the cooking grid from the main chamber. The assembly also includes an elevator mechanism for raising and lowering the frame and cooking grid without the need to remove any elements from within the main chamber. A rotisserie is also provided removably supported on the frame which facilitates withdrawal of the spit and cooking food held on the spit from the main chamber for attending without the need for handling hot food or spit. An overhead infrared heating element, side grill elements, a warming chamber and other features are also disclosed.

Abstract: A retraction device for automatically closing a panel, such as a door or window, after the panel has been opened. The retraction device includes a drum, a coiled spring power assembly for driving the drum, a centrifugal brake for controlling the power assembly and the drum to eliminate slamming of the panel during closing, and a gear train transmission assembly to connect the power assembly and the centrifugal brake. In one embodiment, the drum is a spool which carries a cable to connect the panel to the retraction device. In another embodiment, the drum has a rim which frictionally engages a frame supporting the panel. The centrifugal brake is adjustable to take into account a wide range of panel sizes and frictional conditions. This adjustment can be made through an aperture in the device's housing for quick and easy on-site installation. A one-way clutch mechanism is coupled between the power assembly and the brake to actuate the brake only when the panel is being retracted.

Abstract: A manually-operated pump dispenser (10) for dispensing liquids from a container (28). The dispenser comprises a housing (20), a closure (22) for coupling the housing to a container (28), a pump member (14) having a trigger (84) rigidly extending therefrom and being slidably received in the housing, a coiled spring (16) for biasing the pump member away from the housing, and an adjustable nozzle (12) coupled to the end of the pump member. The pump member and the housing include cooperating slots (86, 89, 90) and flanges (120, 121) and cooperating square portions (71, 115) for resisting the tendency of the pump member to distort about an axis transverse to the housing upon engagement of the trigger (84), thereby maintaining the pump member and the housing in longitudinal alignment. The dispenser includes an inboard valve member (18) received in the housing and an outboard valve (26) formed by the adjustable nozzle (12) and the pump member (14), without the need of an addditional part.

Abstract: A trigger sprayer for generating a spray of liquid from a container comprising five parts including a housing having a tubular piston with an open ended liquid flow passageway therein; a tubular actuator member slidably received over the piston, having a trigger rigidly extending therefrom and defining a chamber therein with a spray orifice at one end; a rod disposed in the actuator member and including a frustoconical skirt forming a valve in the chamber across the spray orifice; an inlet valve carried by the tubular piston and including an extended valve portion slidably seated on the rod, and a biasing spring disposed between the valves. The inlet valve may include a shipping seal member formed integrally therewith and disposed on the inlet passage to seal it until the sprayer is ready for use whereupon the rod will displace or break the seal upon actuation of the sprayer.

Abstract: A manually-operated pump dispenser for dispensing liquids from a container. The dispenser includes a one-piece housing coupled to the container, a dip tube extending from the housing into the container, a one-piece pump member which is slidably supported in the housing and which has a trigger extending therefrom and a nozzle member at the end, a pair of one-way valves supported by the housing and pump member, a one-piece, plastic tubular member which engages the housing and pump member and forms a part of at least one of the one-way valves in the dispenser, and a spring engaging a portion of the pump member and the tubular member for biasing the pump member away from the housing. In a first embodiment, the tubular member forms a part of each of the one-way valves, and in a second embodiment, it forms a part of the inboard one-way valve. In this second embodiment, the outboard valve is formed by the nozzle member and the pump member, both being formed of plastic.
