PATRICK E. TIMON, OF SAN PATRIOIO, TEXAS.

SCRUBBING-NIACHINE.

SPECIFICATION forming part of Letters. Patent N 0. 746,605, 'dated December 8, 1903. Application filed April 1, 1903. Serial No. 150,621. (No model.)

To all whom it may concern.-

Be it known that I, PATRICK E. TIMON, a citizen ofthe United States, residing at San Patricio, in the county of San Patricio and State of Texas, have invented new and useful Improvements in Scrubbing-Machines, of which the following is a specification.

This invention relates to improvements in scrubbing-machines, and the object is to provide a simple and effective machine by means of which floors may be readily and thoroughly scrubbed by the operator while standing in an upright position, thus avoiding the fatigue incident to the stooping position necessary when using an ordinary scrubbing-brush.

The invention also contemplates a machine of this character so constructed that it may be operated to scrub the floor close to the walls of the room, in corners, and beneath furniture or heavy articles difiicult of moval.

With the above and other objects in view the invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of my invention looking atthe same from the front end. Fig. 2. is a rear perspective view. Fig. 3 is a side elevation showing the manner of operating the machine. Fig. 4: is a perspective view of the straps for the lever. Fig. 4* is a perspective view of the strap for the reciprocating arm. Fig. 5 is a. similar view of the cross-piece forming the base of the machine. Fig; 5 is a perspective view of the block carried by the cross-piece. Fig. 6 is a perspective view of the clamp for holding the scrubbing-brush.

Referring now more particularly to the drawings, 1 designates an upright or standard to which near its lower end a cross-bar 2 is attached, so as to project on both sides thereof. Said cross-bar is for-med with a leg 3 and near its opposite end is braced by a bar 4, attached thereto and to the upright and projecting below the cross-bar to form a supporting-leg at that end of the machine. Pivotally attached intermediately of its ends to the upright is an operating-lever 5, having a handhold 6 formed at its upper end and having its lower end working in a guideway formed by a confining-strap 7, attached at one end to the cross-bar and its opposite end to a block 8, carried by the cross-bar. At its lower end said lever is pivotally attached to an arm 9, which slides freely through a confining-strap 10, also attached to the block 8 of the crossarm. Arm 9 at its forward end is pivotally secured between ears 11, carried by the upper sideof a brush-clamp l2. 7 This clamp is provided with flanges 12 to engage the edges of the back of an ordinary scrub-brush 13, one of the said flanges having an in'turned portion 14 to engage beneath the back of the brush, so that the latter may be slid in and out of the clamp. The brush is held rigidly in the clamp by means of the clamping-screws 15, which are carried by one of the flanges 12'. A foot-piece or stirrup 16 to receive the foot of the operator is attached to the upright and brace, and said upright is provided at its upper end with a laterally-extending handhold 17.

In operating the machine the operator places his foot in the stirrup to hold the machine from movement and operates the lever with one hand, grasping the h andhold of the upright with the other. By operating said lever the connecting-arm is reciprocated and the brush moved back and forth upon the floor. When necessary, the machine may be moved forward by the foot of the operator.

By providing the upright and lever with a plurality of holes 18 for the pivot-pin of the lever the pivotal point of the latter may be varied so as to change the stroke, thus obtaining increased or decreased leverage while applying the same pressure.

From the above description it will be see that I have produced a very simple construction of machine by means of which the operator is enabled to readily scrub the floor without stooping, thereby avoiding fatigue and the soiling and wetting of clo,thes, and is also enabled to scrub close to the wall, in corners, and beneath furniture.

Having thus fully described the invention, what is claimed as new is' A scrubbing machine comprising an upright, a handle on its upper end, a cross-bar attached to its lower end and projecting on both sides thereof, a leg on one end of said bar, a brace secured to the upright and to the opposite end of the cross-bar and projecting below the same to form a leg, a block on the cross-bar, a strap having one end secured to the cross-bar and its opposite end to the block thereby forming a guideway, a lever pivoted to the upright and having a series of apertures whereby the pivotal point of said lever may be varied said lever having its lower end riding in the guideway formed by the strap, a vertically-arranged strap secured to the block and so bent as to form a second guideway, an arm passing through said second guideway and having one end pivotally secured to the lever, a clamping-plate pivotally secured to the opposite end of the arm, said clamp having flanges one of said flanges being provided with an inturned portion adapted to engage a brush, and a stirrup or
