Estimating the term…
The measuring device has a bowl. The bowl's capacity is adjusted by a dam structure located within the bowl and attached to a cover structure slidably mounted on the bowl. The slidable cover extends beyond the bowl for use as a handle. The handle has a downwardly-directed extension which is used to support and stabilize the device when the device rests on a flat surface. The handle also has a rounded indentation at the junction between the extension and the handle, so as to reinforce the junction and provide for easily gripping the device. The sides of the bowl structure are flexible so that they can be squeezed together to release the cover so that the device can easily be disassembled and reassembled for cleaning. A detent structure is provided to locate the sliding dam at pre-marked measurement locations. The detent structure is centrally located to permit strengthening of the sliding attachment and reduce wear.
An adjustable measuring device comprising, in combination, a body member having a bowl, said bowl having a forward end wall, a rear end wall, opposing side walls and a bottom wall, a slider member slidably secured to said body member and having a dam element extending into said bowl, said dam element being shaped to fit the internal contours of said bowl so as to form a movable barrier to change the effective volume of said bowl, said slider member extending outwardly from said body to serve as a handle and having an extension adjacent one end, said extension extending in a direction transverse to said slider member to a location substantially in the plane of said bottom wall of said bowl, said body member further having tongues at said side walls' upper edges, and said slider member further having grooves at its side edges, said grooves positively engaging with said tongues so as to securely slidably attach said slider member to said body member, in which a portion of at least one of said side walls of said body member is relatively flexible, whereby said slider member can be disassembled from said body member by exerting inward pressure on said side walls.
An adjustable measuring device comprising, in combination, a body member having a bowl, said bowl having a forward end wall, a rear end wall, opposing side walls and a bottom wall, a slider member slidably secured to said body member and having a dam element extending into said bowl, said dam element being shaped to fit the internal contours of said bowl so as to form a movable barrier to change the effective volume of said bowl, said slider being slidably attached at its sides to said body member and forming a relatively broad and inflexible cover over at least a portion of said bowl, and a detent structure, said detent structure comprising a projection on said body member and a series of depressions in said slider's cover into which said projection fits when it is aligned with one of said depressions, said projection causing said cover to flex when said cover travels over said projection, said detent structure being located at a position spaced inwardly from said sides of said slider substantially on the longitudinally center line of said cover.
An adjustable measuring device comprising, in combination, a body member having a bowl, said bowl having a forward end wall, a rear end wall, opposing side walls and a bottom wall, a slider member slidably secured to said body member and having a dam element extending into said bowl, said element being shaped to fit the internal contours of said bowl so as to form a movable barrier to change the effective volume of said bowl, said slider being slidably attached at its sides to said body member and forming a relatively broad and inflexible cover over at least a portion of said bowl, and a detent structure, said detent structure comprising a projection on said body member and a series of depressions in said slider's cover into which said projection fits when it is aligned with one of said depression, said projection causing said cover to flex when said cover travels over said projection, said detent structure being located at a position spaced inwardly from said sides of said slider towards the longitudinal center line of said cover, in which said body includes a stop member inside said bowl longitudinally extending from said rear end wall and extending upwardly from said bottom wall substantially to the top of said bowl, said projection extending upwardly from the top of said stop member, said depressions being aligned longitudinally on the underside of said cover structure so as to positively releasably engage with said projection when said slider member is moved relative to said body member.
An adjustable measuring device comprising, in combination, a body member having a bowl, said bowl having a forward end wall, a rear end wall, opposing side walls and a bottom wall, a slider member slidably secured to said body member and having a dam element extending into said bowl, said dam element being shaped to fit the internal contours of said bowl so as to form a movable barrier to change the effective volume of said bowl, tongue-and-groove means for slidably securing said slider to said body member, said slider member extending outwardly from said body to serve as a handle, said slider member being relatively inflexible and said side walls of said body member being relatively flexible so as to permit said side walls to be squeezed together to disengage said tongue from said groove to remove said slider from said body member.
