Patent number: 4889619Abstract: A package for holding frangible particulate material, such as breakfast cereal. The package is designed to separate the crumbs or fines from the larger or unbroken and more palatable particles of cereal and to trap the crumbs so they will not recombine with the more edible portion of the cereal when the container is upended to pour the cereal into a bowl. The package has a partition member insert comprised of an apertured screening section and at least one imperforate ramp section inclined towards the screening section. The screening and ramp sections are supported above the bottom of the container to provide for sifting of the crumbs through the screening section, while the package is in its normal upright position, and to allow the crumbs to gravitate into the trapping space, defined by the imperforate ramp section, the bottom closure and the surrounding walls, when the package is tilted during pouring.Type: GrantFiled: June 27, 1988Date of Patent: December 26, 1989Inventor: Bobby R.

Patent number: 4886014Abstract: This invention is a simple, easy to use, self-cleaning pet litter box that separates reusable litter material from solid pet droppings. This task is accomplished through the use of swelled-out chutes strategically formed along the litter box walls combined with a trough-shaped, wire mesh separator that is also built into the litter box. A hole is cut in the side wall adjacent to the wire separator with a tubular-shaped protrusion extending from the outside of this hole in the wall. By using a tilting, rotating motion, the used litter is passed through the chutes in the walls and into the wire mesh separator. The solid pet waste is trapped in the separator while the still usable litter is filtered through. With one final tilt, the solid waste is dumped through the hole in the wall, through the tubular protrusion, and into an attached disposable plastic bag.Type: GrantFiled: August 24, 1988Date of Patent: December 12, 1989Inventor: David G. Sheriff

Patent number: 4602593Abstract: An improved animal sanitary litter box comprising a pair of identical matingly interfitting stackable trays, each of the trays including a slidably movable bottom panel which is movable between a first, closed position for retaining a quantity of litter, and a second, open position. Litter is sifted downwardly from an upper tray to a lower tray, while solid animal excrement is retained on the bottom floor of the upper tray. The excrement can be discarded, the tray cleaned, and then returned to the lower position of the pair of trays. The tray into which the litter was sifted can then be placed atop the now-clean first tray and the litter reused. The size of the openings defined by the movable bottom panel and the floor of the tray is selectively variable for better sifting.Type: GrantFiled: May 10, 1985Date of Patent: July 29, 1986Inventor: Richard B. Gross

Patent number: 4325822Abstract: An animal waste collection and disposal device of the type which contains a litter material into which animal waste matter is deposited including a pair of opposed receptacles. Each of the receptacles has wall portions defining a litter-receiving chamber which is open over at least a portion of one major planar face of the receptacle, with the open portion of each receptacle being in facing relation to the open portion of the other receptacle. A screen member is positioned in interposed relation between the opposed receptacles. Tracks on the screen member slidably receive the receptacles to interlockingly detachably engage the receptacles with the screen member to permit inversion of the assembled receptacles to, in turn, transfilter the granular litter material through the screen. Abutment members limit the longitudinal sliding movement of the receptacles relative to the screen member to align the receptacles relative to the screen member and relative to each other.Type: GrantFiled: July 25, 1980Date of Patent: April 20, 1982Inventor: John H. Miller

Patent number: 4174276Abstract: Small batches of grain for household use are vacuum cleaned in a portable apparatus which can receive vacuum power from the hose of a household vacuum cleaner. Grain requiring cleaning is introduced into the device through a transparent top door and gravitates into a hopper within the apparatus having a restricted grain outlet. When suction is applied through the housing of the apparatus which is vented to atmosphere, air and uncleaned grain are propelled continuously on a circuitous path until the desired clean state of the grain can be observed through the transparent door, at which time another door of the device is opened to permit clean grain to pass into a holding chamber. A waste chamber is also provided in the apparatus and is separated by a screen from the main treatment chamber.Type: GrantFiled: June 19, 1978Date of Patent: November 13, 1979Inventor: Leslie Otness
