Specification of Letters Patent.

Patented May 20, 1913.

Application filed iDecembe r 2, 1911. Serial No. 663,536.

To all whom it may concern:

Be it known that I, FRANKLIN A. BRE'I'I, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented new and useful Improvements. in Scrubbing-h/Iachines, of.

' braces a device in which a quantity of liquid is sprayed upon the floor, a scrubbing brush being operably ,mounted to scrub thefioor after the liquid has been sprayed thereon, after which a suitabledrying mop operates over the floor to dry the surface thereof, the liquid to be'sprayed upon the floor being retained ina reservoir, a second reservoir being provided to receive the liquid after the same has been applied to the door with means for controlling the amount of liquid to be sprayed upon the floor.

In the further disclosure of the invention, reference is to be had to the accompanying drawings constituting a part of this specification and in which similar characters of reference denote corresponding parts in all the views, and in which Figure 1 is a side elevation. Fig. 2, is a vertical sectional view taken on the line 2-2 in Fig. 4, looking in the direction ofthe .arrow. Fig. 3 is a front, elevation, parts i the frame.

Referring more particularly to the views, I provide a carriage comprising a frame 10, preferably consisting of an integral casting, the rear portion of the frame being provided with an upwardly extending plate 11 and having the sides thereof at the upper end of the frame formed into outwardly offset portions 12 to provide a seat 13. Formed on the rear of the frame 10 are outwardly extending studs 14 having wheels 15 journaled thereon and journaled on the front end of the frame 10 is an axle'lG having wheels 17 mounted to turn therewith.

- Mounted to repose upon the seat 13 of the frame 10 and depending therefrom is a waste reservoir 18, the upper end of the said reservoir being offset similarly to the portions 12 to provide a seat 19 on which is mounted to repose a main reservoir 20, the bottom of the main reservoir 20 being adapted to close the waste reservoir 18 as shown in Figs. 2 and 4, the main reservoir 20 being provided with a filling opening 21 normally closed by a cap 22.

Keyed on the ends of theaxle 16, exteriorly of the frame 10, are toothed wheels 23, 24, the toothed wheels 23 being larger than the toothed wheels 24 and mounted to mesh with toothed wheels 25 keyed to the ends of an axle 26 journaled in the forward end of the frame 10 and having mounted to rotate therewith a circular scrubbing brush 27, the latter being mounted so that the free ends of the bristles thereof will contact with the surface of a floor 28. The toothed wheels 24 are mounted to mesh with toothed wheels 29 keyed to an axle 30 journaled in the frame 10 and having mounted to turn therewith a drying mop 31, the latter being preferably circular in shape and mounted within the casing 10 as conveniently shown in Fig. 5.

Secured to the inner sides of the waste reservoir 18 are bearing members 32 in which are mounted to slide horizontally,

studs 33 rigidly formed on the ends of a squeezing roller 34, mounted to rotate with in the waste reservoir 18, an opening 35 being provided at the front end of tlm reservoir 18 and through which the squeezing tions of the casing 36 inwardly to form inwardly extending flanges 38. These instruck portions surround said openings and form a plurality of raised port-ions adapted to impinge against the mop, and also are being provided with shanks 4O encircled by expansible springs 41., the forward ends of these-id springs being adapted to abut against the bearing blocks 39 and the rear ends of the saidsprings being adapted to abut against blocks 42, having the free ends of the shanks 40 slidably mounted therein, the

mentioned blocks 42 being provided with otl'set circular shank portions 43, constituting bolts adapted to receive nuts 44. To permit the accommodation of the nuts on the bolts for securing the bearing members 32 to the inner sides 0.1": the reservoir 18 and the nuts 44 of the blocks 42, the frame 10 is provided with vertically extending slots 45, the said slots being arranged immediately beneath the offset portions 12, thus permitting the bearing members 32 to be'rigid-ly mounted on the inner sides of the reservoir 18 and also permitting the squeezing roller 34 to be properly mounted within the reservoir 18. i i

A rearwardly extending inclined shelf 46 I is secured to the inner front side of the reservoir 18, immediately beneath the squeezing roller 34 for a purpose that will be hereswung upwardly, as will be readily understood.

Mounted on the front end. of the frame 10 is a valve casing 54, having connection, by means of a pipe with the main reservoir 20, a circular apertured spraying tube being mounted to depend from the lower end of the casing 54 and arranged inunediately in front of the scrubbing brush V a valve-57 being connected to a hell cranh lever 58 by means of a link 59, a suitable operating cord (50 being pivotaiiy connei" i, to an arm of the be 1 crank lever 58 th. I l cord 50 being extended rearwai handle 52, a suitable grip (it being: n i of the cord 60, adjacent In the use 0'. Xl'ly( to scrub a floor flu in tilled with a fluid, sucl cleansing solution and is then wheeled upon the floor, the operator being or a soapy stationed in the rear of the 1'; iage with his hands on the grip 52, to user a i ward pressure on the grip and operate riuge over the floor. how by puli'hg on the cord 61, the grip ti) will be c tedto open the valve 57, thus permitting the tluid in the main reservoir 20 to How outwardly through the spraying tube 336, thus spra t i the fluid onto the floor. Now as the car erated over the floor, the revoiuhle me e ment of the wheels 17 and the axie 1 5, wiii impart a rotating movement to the scrubing the 'drying mop 31 by the action of the expansible springs 41, will squeeze the dirty fluid and foreign matter out of the drying mop, the mentioned fluid and foreign matter,

being adapted to flow into the squeezing roller 34, through the openings 37 therein,

the dirty fluid and-foreign matter being then adapted to pass outwardly from the squeezing roller and onto the shelf 46 from which the mentioned fluid will flow into the waste reservoir 18.

From the foregoing description it will b:; seen that when the carriage is operated over the floor, to be cleaned the floor is first subjected to a spray of fluid and then scrublied, after which the surface of the floor is dried by a mop and the foreign matter and dirty liquid, absorbed by the amp in its operation over the floor, is squeezed from the mop i received in the waste reservoir 18, ti leaving the floor in a clean and sanitary corn dition, it being understood that the operator can at all times control the amount of to be sprayed upon the floor while the pidityot' rotation of the scrubbing brush and the drying mop 31 depends ent upon the rapidity with which the carria opt-ratedover the floor.

in a device of the kind described the combin ation of a fluid receiving reservoir, a mop roller disposed exterioi'ly the' of, a roller disp d tr: twersely in said It -voir and m ng i'l'm'relrom partially, St 1 roiler being r'med with a longitudinally spaced .and a shelf downwardly inclined in sai fluid-receivin reservoir and havin its base ,in contact with said second-named roller.

In testimony whereof I afhx my signature in presence of two witnesses.
