ToaZZ whom it may concern: f1

l Be it known that I, Jol-IN M. DOHERTY, a subject of the King of England, residing at Munson, in the Province of Alberta, Dominion of Canada, have invented certain new and useful Improvements in Scrubbing- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to scrubbing machines and has for an object to provide a device of this character that will have novel reciprocating scrubbing brushes that may be readily converted into driers.

A further object of the invention 4is to provide a novel mechanism for reciprocating the' brushes, this mechanism being easily thrown in and out of gear with the ground wheels.

A still further object of the invent-ion is to provide a detachable reservoir that may be manipulated to direct a stream of water in any desired direction.

With the above objects in view the invention consists in the nove-l details of construction and combination of parts hereinafter u 1at their' opposite ends to the front bar 23 Iand foremost of the cross braces 31,'and

fully described and claimed, it being understood that various modificationsA may be made in the minor details of construction within the scope of the appended claims.

In the .accompanying drawing formingv partof this specification, Figure 1 is afplan view of the device, Fig. 2 is a side elevation of the device, Fig. 3 is an enlarged longitudinal sectional view taken on the line 3-3 Fig. 1, Fig. 4 is an enlarged cross sectional view taken on line 4-4 Fig. 1, Fig. 5 is a fragmentary view through the clutch.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, 10 designates an axle, the opposite ends of whichV are equipped with ground wheels 11. The axle is incased in a sleeve 12 which does not rotate with the axle and to which is iixed the side bars of a handle frame 13. The sleeve 12 is made in sections to permit of a bevel gear 14 being slidingly tted on the shaft, this bevel gear being mounted for rotation with the shaft by mea-ns of a set screw 15 projecting into a slot 16 vformed longitudinally in the shaft. The gearis provided in its hub with a peripheral groove 17, into which loosely fits a finger 18 carried by a lwith ajournal box 26.

sleeve 12.

sleeve 19 which is mounted for sliding movementon one of the sections of the sleeve 11 by means of a set screw 2O projecting into a longitudinal slot 2l formed in this secs n u tion. By manually sliding the sleeve 19 or 1 clutch as it may be called the gear is thrown into and out of mesh with a hereinafter described brushl actuating mechanism.

A skeleton frame projects .forwardly from o n n n the axle, t-his frame comprising a sidebar V22, a `frontbar 23 and a stub side bar 24, the

latter. terminating in a vertically disposed elliptical loop 25 which isequipped axially A driven shaft 27 is arranged in parallel;l ism with the side bar 22 and is journaled 'near'its forward end in the journal box 26,

32fwhich receive the intermediate portion ofy Ithe driving shaft. 4 A pair of longitudinal braces 33 are fixed these longitudinal braces are provided inter; mediate their endswith alined journal boxes 34, thesejournal boxes' alining with a jouri nal box 35 carried by the side bar 22.' A rod 36 is loosely fitted in the 4alined journal boxes and terminates at one end in the yoke 37 which pivotally receives one end of a pitman 38, this pitman being connected to the crank pin 30. As the driven shaft rotates, the rod 36 will be reciprocated through the instrumentality of the pitman.

Mounted on the sliding rod 36 is a pair of brushes or brooms 39, and as each broom and its mountings is identical in construction but one will be described. An approximately rectangular bracket 40 is provided with a transverse orifice 41 of sufficient size to loosely receive the sliding rod, and is further provided with a vertically disposed socket 42 that receives the stem 43 of the broom. Set screws 44 are threaded into the bracket and serve to lock the bracket to the sliding rod and the broom to theV bracket. By unloosening the broom set screw, the broom may be rotated so as to bear on .the floor entirely in a line parallel to thelonthe bracket set screw the bracket may be ro-l gitudinal axis of the supporting frame or. may be rotated to `any angular positionv transversely of this axis. By unloosening tated upon the sliding rod so as to cause the broom to incline to any desired position to the surface being scrubbed.

A shallow pan 45 is riveted or otherwise fixed at its center to the pointof intersec? tion of the rearmost cross brace 31 and a longitudinal brace 46 which is secured at its opposite ends 'to the axle sleeve and fore most of the cross braces. This pan loosely receives a bucket 47 having a spout 48 in which is located a slide valve 49 that regulates the discharge of water from the bucket or reservoir as it may be called. The reservoir may be rotated in the pan so as to direct the position .of the spout in any `desired directionso that the flow therethrough will be directed against any desired portion of the surface being scrubbed. A pair of` handles f 50 are fixed to the reservoir and form means for removingv the reservoir from its supporting pan when necessary.

For supporting the free end of the skeleton frame a caster 51 is secured to the lower 'portion yof the elliptical loop 25, and another caster 52 is secured to the opposite side of the skeleton frame diametrically opposite the caster 51. These casters permit of ythe machine beingreadily guided over the surface to be scrubbed and hold the free end of the frame spaced a constant distance from 4this surfacel so that brooms may be adjusted to bear withV any desired force against the surface.

` Itv will be noted that the brooms are disposedbroad'side to the longitudinal axis of opie: o'f lthis patent may be obtained for the skeleton frame. In this position the brooms act as scrubbers. By giving the brooms a half turn in their sockets they will be disposed broadside to the cross axis of the frame and in this position act as driers. It will be observed that when the brooms are in position tov serve as driers, whereby rotating the brackets to any desired extent lon the sliding rod, the brooms will be inbar .equipped with a vertically disposed closed loop, a driving shaft having a disk within said loop, a pitman on said disk, a reciprocating rod connected to said pitman and extending at a right angle to said side bar, Aa rotatable bracket 0n said rod, a broom having a stem loosely fitting in said bracket, and set screws adjustably securing said bracket to said rod, and said stem to said bracket.

In testimony whereof, I aiix my signa-- of two witnesses. JOHN M. DOI-IERTY. i' Y Vitnesses I-I. L. MAGEE,
