7 FLOOR OILER AND WAXER Filed March 25, 1955 f f 4/ T 1 /7 Patented Jan. 16, 1934 ATENT orriea FLOOR OILER AND WAXER Edgar F. Hawley, Pueblo, 0010. Application March 25, 1933. Serial No. 662,775 Claims. (01. 91-39) This invention relates to devices for oiling and waxing floors and particularly to a device of this character in which there is provided a tank for containing oil or liquid wax movable over the 5 floor and provided with brushes for rubbing in the oil or wax and polishing the floor.

The general object of the invention is to provide improved means whereby the brushes may be mounted upon the tank and whereby they may 19 be adjusted so as to be used until practically all the bristles have worn away.

9 A further object is to provide a structure of this character comprising an oil tank mounted upon wheels and carrying brushes, providing a spraying device for spraying the oil on to the floor in advance of or through one or more of the brushes and provide a manually operable pump whereby the oil may be sprayed from time to time on to the floor and. in this connection to provide means whereby the handle of the oiler and waxer may be used to operate the pump.

Otherobiects will appear in the course of the iollowingdescription.

My invention is illustrated in the accompanying drawing, wherein:-

Figure 1 is a side elevation of my oiler and waxer; Y

Figure 2 is a top plan viewthereof;

Figure 3 is a longitudinal section showing. in dotted lines the handle broken and the plunger raised.

Referring to this drawing, designates atank generally of any suitable material or construction which may have any desired form in plan. This tank is provided with the floor or bottom ,11 supported on wheels 12 and the tank is provided with an inlet opening 13 through which the tank may be filled and which may also be used as a vent for permitting the inlet of air when the i liquid is allowed to flow from the tank.

Mounted upon'the exterior of the tank at the front and rear thereof are the guide brackets 14 extending through which are the bolts or spindles 15 which carry thebrushes 16, the heads of'which are designated 17. These brushes extend transversely across the tank and one brush is located at the front of the tank and another at the rear of the tank. A coiled spring 18 surrounds each spindle or bolt 15 and bears against the lowermost bracket and against the head of the brush and thus the brushes are urged downward. This downward movement of the brushes, however, is limited by nuts 19 carried upon the upper ends of the spindles 15 or bolts and hearing against the uppermost brackets 14.

By tightening these nuts or turning them downward, against the bracket 14, the spindles and, therefore, the brushes are raised, compressing the springs 18. By turning the nuts oiT to any desired degree, the brushes will be forced downward by the springs 18. Thus as each brush wears, the corresponding nut 19 may be turned ofi to any desired degree to allow the brushes to move downward and thus the brushes may be used until practically all of the bristles have worn off.

Within the tank 10 there is disposed the false bottom 20 dividing the tank into two portions. The upper portion 21 constitutes an oil reservoir or liquid wax reservoir while the lower portion is empty. Extending downward through the top of the tank and through this false bottom 20 and to the bottom 11 of the tank is a cylinder 22 provided with an air inlet opening 23 adjacent its top and below the top of the tank 10 and just above the false bottom 20 being provided with the inlet openings 24.. Operating within the cylinder is a piston 25 having a piston rod 26 which extends out through the top of the cylinder and is provided at its upper end with an eye 27.

Mounted upon the top of the tank are the two spacedbrackets 28 which are each approximately triangular in form and attached to the top of the tank in any suitable manner, these brackets having extensions 29 which extend upward and rearward from the tank. The upper handle section 30 is pivoted at 31 between these brackets 28 as shown in Figure 2.

Coacting with the upper handle sectionSO is a lower handle section 31, it being understood that these two handle sections together constitute the handle and these two sections are hinged to each other by a hinge 32 whose pintle is disposed in alinement with the joint 33 between thetwo sections. Extending from the handle section 31 is an elongated downwardly and forwardly extending shank 34 whose end is curved as at 35, the extremity of this curved portion passing through the eye 27. Disposed above and below the shank 34 are the fulcrum pins 36 and m 37 which extend from one bracket extension 29 to the other. These pins 36 and 37 each constitute a fulcrum for the shank 34 which, with the handle section 31, constitutes av lever whereby the plunger may be raised or lowered as will. be later explained. A coiled contractile spring 38 is attached to the handle section 30 and to the top of the tank and acts to draw the handle section 30 downward.

Leading from the lower end of the cylinder 22 forth and actuating the plunger.

is a discharge pipe 39 which extends to the front wall of the casing or tank 10, then extends upward to the top of the tank and then extends directly downward as at 40 and terminates in a transversely extending spray head 41 having a plurality of perforations discharging downward through a slot 42 formed in the head 1'7 of the front brush. This slot 42 extends entirely through the brush head to the floor so that the spray from the sprayer 41 is discharged downward through this slot and through the bristles of the front brush on to the floor.

The operation of this mechanism is as followsz-Of course the machine is designed to be pushed and pulled over the floor to be polished and the oil or liquid wax is designed to be forced by the pump piston out through the sprayer.

Assuming that the reservoir 21 is more or less filled with oil or liquid wax and it be desired to force oil or wax on to the floor, then the handle section 30 is raised, turning upon its fulcrum 31*. This, through the hinge 32, causes the depression of the handle section 31 and the depression of the rear end of the lever constituted by the shank 34 acting against the fulcrum pin 36. This will act to lift the plunger 25 above the openings 24 so that oil will flow into the space between the plunger 25 and the lower end of the cylinder 22. Upon a depression of the handle section 30, the parts will be brought back to the position shown in Figure 3, causing the lever constituted by the shank 34 to bear against the fulcrum 37 and thus depressing the forward end of the shank and depressing the plunger, thus positively forcing the oil in the cylinder out through the pipe 39 and on to the floor. With this mechanism, whenever it is desired to force oil or wax out in advance of the polisher, the handle section 30 is oscillated which will have this effect. The spring 38 keeps the jointed handle rigid while operating the machine back and forth across the floor. With this construction, there is no necessity of the operator stooping in order to operate the pump and it avoids the necessity of the operator placing his foot on top of the oiler in order to balance the same while pumping oil.

A mechanism constructed in accordance with my invention distributes liquid when and where desired at the will of the operator. In operation it has been found to save oil, prevent the smearing up of floor boards, casings or woodwork and is easy to operate. The handle serves a double purpose of propelling the machine back and A normally operating position is obtained except when the plunger is being raised or lowered. The ejection of the liquid is entirely under the control of the operator.

While I have illustrated a particular construction, I do not wish to be limited to this as obviously many minor changes can be made therein without departing from the spirit of the invention as defined in the appended claims.
