Abstract
The present invention relates to a relatively lightweight, portable, hand controlled finishing machine for finishing cement like surfaces. The cement finishing machine comprises an elongated shaft that makes up the main frame thereof, and a rotary wheel rotatively mounted to said elongated shaft and driven by an electric motor also mounted to said elongated shaft. Finishing elements such as rocks, brushes, or even trowels are detachably secured to an outer exposed radial face of said rotary wheel. In operation, the cement finishing machine is supported adjacent a wall or surface to be finished and during the course of operation, an operator is able to manipulate and control the main frame such that the finishing elements engage and act upon the surface being worked.
Claims12
A portable hand held and controlled cement finishing machine comprising:
- (a) a main frame structure including an elongated shaft;
- (b) a transverse shaft secured to said elongated shaft and extending outwardly therefrom;
- (c) a rotary wheel rotatively journaled on said transverse shaft and rotatable thereon and including an outer radial face;
- (d) mounting means secured to said elongated shaft of said main frame at a selected distance from said rotary wheel;
- (e) power means mounted on said mounting means;
- (f) drive means drivingly interconnecting said power means with said rotary wheel;
- (g) finishing means secured to said outer radial face of said rotary wheel for engaging a surface being finished and imparting a finishing action to the surface as said rotary wheel is driven;
- (h) a first handle secured to said elongated shaft on the side opposite said rotary wheel and extending outwardly therefrom and in general parallel relationship with said transverse shaft supporting said rotary wheel;
- (i) a second handle secured to said elongated shaft in the vicinity of said first handle and extending therefrom;
- (j) a cable assembly secured to said main frame for supporting said finishing machine from a selected height while the same is guided and controlled by an operator through said first and second handles;
- and
- (k) squaring arms mounted to said elongated shaft and extending outwardly therefrom on opposite sides of said rotary wheel for squaring the rotary wheel and said finishing means with a surface being finished.
A versatile portable hand held and hand controllable cement finishing machine for finishing walls and ceilings comprising:
- a frame structure having an elongated shaft;
- a rotary wheel rotatively mounted to said elongated shaft and including an outer radial face;
- cement finishing element means secured to the outer radial face of said rotary wheel for engaging and finishing a cemented surface;
- a power source mounted to said main frame structure in spaced apart and off set relationship relative to said rotary wheel;
- drive means drivingly interconnecting said power source and said rotary wheel for driving the latter;
- a cable assembly mounted to one end of said frame structure and including a cable that is generally secured to an elevated point such that the cement finishing machine is suspended along a working wall;
- handle means secured to said main frame structure and extending therefrom for enabling an operator to guide and control the cable suspended cement finishing machine along a certain wall being worked, said handle means including a first handle extending outwardly from said elongated shaft opposite said rotary wheel about an axis that extends perpendicular to the plane of said rotary wheel and a second handle extending from said frame structure at an angle to said first handle and in a plane generally parallel to said rotary wheel, wherein said first and second handles cooperate with said cable assembly to form the total support and guidance control of said finishing machine;
- means secured to said elongated shaft and projecting outwardly therefrom about said rotary wheel for maintaining the cement finish machine and rotary wheel in proper parallel alignment with a surface being worked;
- a ceiling finishing attachment including a stud shaft assembly adapted to be fixed to said elongated shaft opposite said rotary wheel and in parallel alignment with the axis of rotation of said rotary wheel;
- a vertical support post operative to fit and align with said stud shaft assembly such that the radial face of said rotary wheel may be maintained adjacent a ceiling surface;
- and dolly means having said vertical support post secured thereto such that the cement finishing machine when supported through said vertical support post and said dolly means may be moved about the ceiling surface by moving said dolly means.
