Manual floor sweeper
First Claim
1. A floor sweeper of the manual type including a casing having a hollow space therein, a pair of front and a pair of rear wheels rotatable on the floor to be swept, and one pair of roll brush brooms arranged at a center portion of the hollow space of said casing and juxtaposed longitudinally in parallel and adjacent to each other in a manner to rotate inwardly, as said wheels rotate, so as to sweep up the dust on the floor into the hollow space of said casing,wherein the improvement comprises:
- two substantially enclosed spaced parallel housings one on each side of said casings;
a gear train accommodated in each of said housings and including front and rear drive gears positioned in each of said housings coaxially with each pair of said front and rear wheels, front and rear brush actuating gears interposed between said front and rear drive gears supported coaxially with said roll brush brooms, and coactive means interposed between said front and rear brush actuating gears spacing said roll brush brooms and for effecting the inward rotation of said brush actuating gears and accordingly said roll brush brooms; and
selective means interposed between said drive gears and said brush actuating gears for selectively effecting power transmission in accordance with the forward and backward movement of said floor sweepers, such that the drive power from the drive gears, which are located at a front position with respect to the direction of advance of said floor sweeper, may be transmitted to the adjacent brush actuating gears by said selective means and to the brush actuating gears of the far side by way of said coactive means, thus allowing the drive gears in the rear position to idle.

Abstract
Herein disclosed is a manual floor sweeper including a casing, a pair of front and a pair of rear wheels and a pair of roll brush brooms juxtaposed longitudinally in parallel with each other in a manner to rotate inwardly in response to the rotation of the wheels so as to sweep up the dust on the floor into the hollow space of the casing. Two substantially enclosed housings are juxtaposed to each other at the both sides of the casing. Each of two gear trains is accommodated in each of the housings and includes a pair of drive gears, a pair of brush actuating gears, and a pair of coactive gears. A selective means is interposed between the drive gears and the brush actuating gears for selectively effecting power transmission between them, so that, in accordance with the forward and backward movements of the floor sweeper, the drive power from the drive gears, which are located at a front position with respect to the direction of advance of the floor sweeper, may be transmitted to the adjacent brush actuating gears by way of the selective means and further to the brush actuating gears of the far side by way of the coactive gears, thus allowing the drive gears in the rear position to rotate idly.
