SCRUBBNG MACHNE.

Application led January 26, 1921. Serial No. 440,076.

To all 'whom it may conc-ern Be it known that l, QUINTO FAUsriNi, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented new and useful lmprovements in Scrubbing Machines, of which the following is a specification, the principle of the invention being herein explained and the best mode in which l have contemplated applying that principle, so as to distinguish it from other inventions.

This invention relates to scrubbing m a chines, and particularly to that class of such machines which are electrically driven and are especially designed for duty in hotels, otiice buildings` apartments and other buildings provided with large floor spaces. More particularly, this improved machine is deY signed to be self-contained as to all of the functions required of such a machine, and to be thoroughly efficient in its operation, economical in cost of operating the same, and includes essential improvements over the Letters Patent granted to me under date of April 23, 1918, No. 1,263,396.

The annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting vbut one of various mechanical forms in which the principle of the invention may be applied.

In said annexed drawings:

Figure 1 represents a side elevation of the improved machine embodying the invention- Figure v2 represents a horizontal section, taken in the planes indicated by the line lI--II, Figure l;

Figure 3 represents a front elevation of the machine; f

Figure 4 represents a verticalrsection of a fragmentary portion, taken in the plane ndicated by the line IV-IV, Figure 3;

'Figure 5 represents a vertical section of a fragmentary portion, taken in the plane indicated by the line `V-V, Figure 2; and

Figure 6 represents, upon an enlarged scale, a vertical section of a fragmentary portion, taken in the plane indicated by the line VL-VI, Figure 2.

Referring to the annexed drawings, lv

shall first refer by reference numerals to a number of the main parts of my improved machine, which are'a frame 1, provided with suitable sub-divisions properly designed to support and aline the various operating parts, as will be hereafter fully explained; a motor 2; an extension cord or power cable 3; a fresh water tank e; a tank 5 used for dirty water; a plurality of scrubbing brushes 6; a wiping roller 7 a drum 8 uponv which the power cable is automatically wound or from which it is automatically un- Awound; a main longitudinal driving shaft 9 leading from the motor; a transversely arranged driven shaft 10, from which the cable drum 8 is driven by a belt 69; a longitudinal shaft 11., for driving the wiping roller; 12 an eccentric for driving the scrubbing devices; 13 an eccentric strap with integral depending members 14 adapted to support the scrubbing devices; i5 a transverse stub shaft supported by said depending members; a plurality of gear sectors 16, fixedly secured to said stub shaft, each gear 16 being adapt-ed to engage with a rack 17 which extends vertically from each brush head; a universally liointed shaft 18, connected with a shaft 19 adapted to actuate the transversely disposed stub shaft 15 to vertically adjust the scrubbing brushes in their proper relation with respect to the floor; two comparatively large front Wheels 20 and two comparatively small casters 21 for supporting the front and rear of the machine, respectively, and upon which wheels and casters the machine is designed to be rolled about easily by means of a handle 22, a main pipe 23 from the fresh water tank l connected with the fresh water distributing pipes 24; a main pipe 25 leading into the tank 5 designed to receive the dirty water; one end 26 of the eccentric strap being connected to a suitable piston 27 adapt ed to be reciprocated in a pump cylinder 28 for conveying the dirty water through pipe 9 25 and into the dirty water tank; a trolley pole 29 with the swiveled arm 30 carrying trolley wheels 31, said pole 29 being mounted upon the top of the frame 1.

Other features with various details will now be filled into the several main parts hereinbefore mentioned to connect the same up into an operative whole comprising my improved and novel scrubbing device.

The motor 2 is provided with the main longitudinal drivin@ shaft 9 upon the outer end of which is mounted a worm 32 which engages with worm gear wheel 33 lixedly mounted upon the transverse shaft l0.y and lixedly secured to said shaft 10 is a bevel gear wheel 34 adapted to mesh with a bevel gear wheel 35 rigidlyI mounted upon one end oifa. vertically disposed stub shaft 86, and tothe other end of said shaft 36 is iixedlyv secured the eccentric 12 to which a rotary motion is imparted by the said stub shaft, for the purpose hereinafter described. The worm 32, worm gear wheel 8?), bevel vgear wheel 34, and bevel gear wheel are contained within a metallic casing B8 suit-r ably supported by the frame, said casing havingopposite inward extensions 39 forining bearings for. the shai't 1Q, and a depending extension constituting a bearing for the stub shaft 36, as clearly shown in Figure 5.

Fitted to the eccentric 12 is an eccentric strap 13, provided with lateral integral. extensions 41 and integral depending

eXten sions

14 and 43 said extensions 43 being adapted to support a plate 44, to whichl plate is suitably and iixedly secured a. plurality of smallervplates 45, eachr ot said plates 45 being adapted to receive an Vupright toothed rack member 17, to the lower end of which is secured a scrubbing brush,while its upper end is adapted to engage with the gear sector 16,y each of said sectors beine' mounted upon the transverse stub shaft 15, and

f'y so edly secured thereto bya set screw 47 said stub shaftbeing suitably supported bythe depending extensions 14, as shownin Fig yure 3, hence it will be readily perceived that whena rotary motion is imparted to the eccentric'by means oi the main drive shaft, the

' transverse shaft 10 and stub sha'lt 36, a rotary movement willl be imparted to the eccentric strap, thereby transmitting arotary movement tolthe scrubbing` brushes'through the depending extensions integrally con- Vnectedto the eccentric strap which eXtensions indirectly supportand carry the said brushes,k said rotary movement being ime parted to the brushes and their supports in unison.

"Fixedly secured to one end of, the stub shaft'l is a worm gear wheel 4S adapted to meshv with a worin 49 secured to oneend ,of the universally-mounted shaft (19,.the other end of said shai't 19being` secured by a universal joint to one end oit the shaft 18while the other end 'of the latter is joined in a sim-` ilar manner tov .a shaft'Q, provided at its outer end witha handle y53, and by the proper manipulation et' said handle the scrubbing brushes are vertically adjusted into the desired position with respe t to their contact with lthe floor, by means of the movement oi saidstub shaft 15, which imparts movement to the gear sectors 16 meshing with the toothed rack members 17, and thereby regulating the position of the brushes with relation to the floor, as will Abe readily understood.

' Secured to one end of the transverse shaft n 10, and within a casing 54 carriedby the frame, is ii-Xedly secured a bevel gearwheel 55 meshing with a similar bevel gearwheel 56, also positioned within said casing and ixedly mounted upon one endrof vthe lon gitudinal shaft 11, and to the other end of lsaid shaft 11, issecured a gear wheel 58,

adapted to mesh with a gear wheel 59 mounted at one end of the axial support of the wiping roller 7, by which means it will be i obvious that ai'otary| motion is imparted to the said wiping'roller 7.

The construction,shape and arrangement.v of the wiping roller asfplainly shown 1n 'Figures 1, 2 and 6, is widened out to'com. Y prehend a space somewhat more thanthe width 'of the machine so that the dirty watery which usually spreads .beyond the brushes may be gathered as the machine is propelled;

The "said wiping roller is oiI cylindrical shape, the periphery ofwhich is covered;y

with a series of alternate strips or sections'r4 Y of rubber 60 and cloth .or felt61, suitably secured. thereto, the cloth or felt being adapted to absorb all otl the dirty water and mois.

ture as the machineis propelledr andfthfer' roller caused to rotate adjacent the floor, said y rubber sections being adapted `to ypreventthe said cloth or felt sections kfrom stickingv or `adhering to beach other.' Suitably, 'sup.

ported by the frame directly above the` roller 7 and in contact therewith is apressure roll 62 and resting in contact with each outer endv portion of said roll-62 isay Ver.-

tically movable plate @Shaving an elongatedslot 64 through whichprojects a stationary-- pin 65 to which one end'ofa Vcoiledl tensionl spring 66 is secured, the other'endofthe spring being secured to. apin 65` carriedby'.,`

said plate, while the upper end of the plate 'l' 63 is pro'vidediwith a suitable handle 67 by which the plate is raised against they-tension.

or' said spring and "the tension onthe pres!y sure roll is thereby relieved,

Byjreference to. Figure. 6, it'will be seen water tank. in the scribed. 'f

The shaft 10 pulley l37 fixedly secured thereto,` and running over said pulley is abelt 69' which` also runs over an enlarged*cylindrical,eXtension, 70 formed to one side of the 'cable drum,` said drum being rotatablymounted. onv a4 shaft 71 supported bytheframe.l V'Iheesr 1 tension cord or power cable 3 after; passing'v, between the two Vtrolley wheels 31, emergesf from which the cable drumrk f 8 is driven is providedatone end withraVA from a slot 31 in thepolefZrQ, and ispafssedr to and under a wheel 72looselyfmounted.l @on a .Shaft 73 and es@ es cable is wound upon the cable drum 8. Said wheel 72 and shaft 73 are supported by one arm 74; of a triangular casting pivoted to and supported by the shaft 71, the other arm 75 of said casting being also provided at its outer end portion with a wheel 76 loosely mounted upon a shaft 77, and secured to a pin 79 fixed to the arm 74 is one end of a coiled tension spring 7 8, the other end of said spring being secured to a pin 79 carried by the frame, thus constituting belt tightening and loosening means, whereby so long as there is slack in the power cable to be taken up, the Wheel 76, acting under the tension of spring 78, will remain in contact with the belt l69, thereby tightening the belt, causing the same to automatically transmit a rotary motion to the cable drum to wind the-'slack cable thereon, but as soon as the slack shall have been taken up and the cable becomes taut. said cable will cause the wheel 72 to be lifted against the tension of the spring 7 8, thereby lifting the wheel 76 from contact with said belt, thus allowingthe. belt to rest loosely around the pulley 68 and drum extension 70 and automatically causing the drum to remain idle until additional slack occurs, as plainly shown in Figure 1. l

Secured to one end portion 26 of the eccentric strap 13 is a suitable piston 27 of a pump, to which a reciprocating movement is imparted by the movement of said strap, said movement of the piston causing a suction in the pipe 81 and the connecting pipe 82 terminating adjacent the top of the dirty water tank 5. Secured in lateral branch pipes 81 of the pipe 81 are check valves 83 and 83', Figure 2, of which valve 83 opens inwardly and valve 83 outwardly, so that it will readily be understood that an outward movement of the piston 27 will create a suction above the pipe 82 in the dirty water tank 5, and an inward movement of the piston 27 will force air out by the valve 83, the branch pipe 81 in which this valve is located being open to the atmosphere.

Securedvat a suitable point in the pipe 23 leading from the fresh water tank is a suitable discharge regulating valve (not shown) which is operated by a hand wheel'84: connected to a shaft 85, said pipe 23 communicating with the fresh water distributing pipes 24. ,lt will be understood that any suitable or desirable means may be employed for iilliug the -fresh water tank and for draining off or emptying the dirty water tank.

The front wheels 2O are mounted in suitable bearings supported by the frame, and the rear wheels or casters 21 are supported on axles mounted in swivel brackets 86, which brackets support the main frame 1 at the rear portion thereof.

The scrubbing portion proper of the shaft 19 slides in a sleeve 90, said sleeve 90 being secured by means of' a pin 91 to the rearend of a shaft 92 upon which the worin 49 is formed. By means of elongated slots 93 formed in the sleeve90 into which a pin 94 extends, provision is made for the reciprocating movements of the eccentric 12, and

hence the pin 94, relatively to the sleeve 90.I
