Abstract
Abstract A machine designed to clean mats, rugs and the like by means of a high powered liquid spray impinging upon the mats as they are conveyed through the machine. An endless driven belt engages the upper surface of the mat and carries it through the machine, over grates through which the spray is directed. A pair of driven, spring-loaded rollers are positioned at the entrance and exit to the machine such that the first pair of rollers pulls the mat into the machine and the second pair of rollers forces the mat out the exit of the machine while simultaneously squeezing the excess water from the mat. Access to the interior of the machine is accomplished by a top which may be lifted from the tank of the machine by means of a lever and cam arrangement.

Claim 1
Independent Claim
185 words
A cleaning machine of the type designed to clean mats, said machine comprising: a tank, a top movably connected to said tank, conveyor means arranged to convey said mat through said machine and comprising an endless belt movably mounted within said top, a plurality of conveyor rollers mounted in said tank in opposed working relation to said belt, at least one strip belt mounted within said tank on at least two of said conveyor rollers, whereby said endless belt, said conveyor rollers and said strip belt at least partially define a path of travel of the mat through said machine; driving means disposed on said machine to drive said conveyor means, raising means connected to said tank and arranged relative to both said tank and said top and comprising a cam rotatably mounted on said tank, a cam rider attached to said top, said cam and said rider arranged in cooperative relation such that rotation of said cam causes separation of said belt from said plurality of conveyor rollers, whereby the interior of said machine is accessable upon separation of said top from said tank.
