  • Patent number: 9962042
    Abstract: An article support for a surface, the support including a base having a first end portion and a second end portion, the base first end portion is adjacent to the surface. A reservoir is disposed within the second end portion, the reservoir having a terminating margin periphery forming an aperture. An omni-directional substantially planar extension originating at the margin periphery and outwardly terminating in an outer perimeter, the planar extension has a segmented primary surface and a secondary surface wherein the secondary surface faces the first end portion. A portion of the primary surface is formed from an inverted equilateral square pyramid wherein an apex of the pyramid is disposed within the aperture. Operationally, the article is placed upon the primary surface, the article having a plurality of point contacts upon the primary surface causing the article to clear the margin periphery for drainage from the article into the reservoir.

  • Patent number: 4007855
    Abstract: A liquid metering dispenser is actuated by a trigger. The trigger releases a valve rod which is spring actuated to close a fluid pressure inlet, opening the discharge outlet of the dispenser to release a stored measured charge of liquid by operation of a spring actuated piston. The trigger is cocked by drawing the valve rod to close the discharge valve and open the liquid pressure inlet; the liquid under pressure enters the storage chamber, compressing the piston spring until it strikes an adjustable stop. The piston and spring assembly is readily removable for cleaning and servicing.

  • Patent number: 3952919
    Abstract: An adapter for attaching and sealing a liquid supply reservoir on a liquid dispenser of the metering type comprises a reservoir receiving body and a detachable element for securing the body to a dispenser with a seal piercing needle in position to receive the contents of the reservoir. A pivoted clamp is provided for clamping the reservoir on the body when the seal has been pierced and holds the reservoir securely to the body during use of the dispenser. A nut secures the detachable element on the dispenser, a spring bias being provided to afford adjustment of the element with respect to the nut. A check valve is provided to prevent return of liquid to the reservoir and facilitates the use of collapsible supply reservoirs.
