Definitions

  • This invention relates to devices for supplying Wax or other preparations to floors, more particularly to devices especially applicable to and adapted as attachments for polishing machines in which rotary brushes or other rotating polishing members are employed.
  • the invention has special reference to such devices that act to supply wax or other fluid preparation to a floor for spreading and polishing by the rotating polishers of the machine.
  • This application is a continuation of my application Serial No. 552,652, filed December 12, 1955, now abandoned, which is a continuation of application Serial No. 156,745, filed April 19, 1950, now abandoned.
  • Wax-containing or other fluid-holding devices in combination with polishing machines to deposit wax or other preparation on a floor for spreading and application by the machine.
  • An objection to these devices is the tendency of the rotating brushes or polishers to splash or scatter the wax deposited on the floor so that furniture or Walls often will become soiled.
  • Another objection is the in ability of the devices to regulate the amount of wax or other preparation deposited on the floor so that uniform application will be obtained.
  • an object of the present invention to provide a wax applicator or depositor which may be attached to and supported by a floor polisher, and will regulate the amount of wax deposited on a floor. It is also an object of the invention to provide a device of this kind that will deposit the wax on the floor in such a manner that splashing and scattering will not occur.
  • FIG. 1 is a side elevation of a polisher of the three-disk type to which the improved wax-applying or floor-treating device is applied:
  • FIG. 2 is a top plan view of the fluid applicator and the polisher, the three disks of the latter and the driving belt therefor being shown in dotted lines;
  • FIG. 3 is a top plan View of the tank or container for the wax or other floor-treating preparation
  • FIG. 4 is a vertical sectional view through the tank and valve means therefor and parts of the polisher, taken on a plane parallel with FIG. 1;
  • FIG. 5 is a sectional view taken on line 5--5 of FIG. 4, looking in the direction of the arrows.
  • a floor polishing machine of a known type which includes a housing 9 having an upstanding part It) of reduced cross-sectional area for the electric driving motor, and a handle 11, the lower end of which terminates in a fork 12 having spaced apart arms pivotally connected to the motor housing part 10.
  • Brushes 16, to which polishing disks of felt or other suitable material, not shown, are often attached, are detach- 3,139,640 Patented July 7, 1964 ably connected to each of three disks 13, 14 and 15, respectively, which rotate around vertical shafts parallel to each other.
  • a device 19 for applying wax or other floor-treating preparation is attached to the rear of the housing part 17, and includes a tank or container 20 in the form of an elongated receptacle formed of upper and lower sections or halves 21 and 22, respectively, joined together by soldering, for example.
  • the tank or container 20 is detachably held at the rear edge of the housing part 17 by two pivoted supporting rods 23, preferably of spring wire, and two hooks 24 forming portions of props fixed to the lower section 22 of the tank 20.
  • each of the rods 23 is bent downwardly, and the downwardly bent ends are pivotally received in bosses 25 to connect the rods 23 to the tank 20.
  • This pivotal attachment of the rods 23 to the tank 20 enables the rods 23 to be folded from the position shown in FIGS. 1, 2 and 4 to the position shown in FIG. 3 over the top of the tank 20 and substantially parallel to the longitudinal axis thereof.
  • the outer free ends 26 of the rods 23 are looped and angularly bent to fit into openings in bolts 28 which pivotally attach the spaced apart arms of fork 12 to the motor housing part 10.
  • Looped or hookshaped portions 29 of the rods 23 yield sufiiciently to enable the ends 26 to be snapped into the holes in the bolts 28, and serve as finger pieces to enable the hook-shaped rods 23 to be disconnected easily from the polishing machine when it is desired to detach the fluid-supplying device 19.
  • the hooks 24 at the bottom end of the tank 20 engage the lower portion of the protective rubber ring 18, as clearly seen in FIG. 4, and, together with a foot 30'provided on the bottom of the lower section 22 of the tank 20, constitute three legs on which the tank 20 can be supported on a flat surface when the tank is detached from the polishing machine.
  • the upper section or half 21 of the tank 20 is provided with a filling opening 31 normally closed by a threaded cap 32.
  • the tank 20 is provided with a valve member 33 in the form of a needle which is axially movable through a guide or bushing 34.
  • the region about the opening 35 in the bottom section 22 of the tank 20 serves as a valve seat.
  • the valve member 33 is provided with a pointed or conical lower end 36 which cooperates with the opening 35 to control the discharge of wax or other treating preparation from the tank 20.
  • the valve opening 35 is enveloped by a number of guides 37 which form a guide passage extending to the outlet opening 35.
  • An air vent, which is provided at the top of the tank 20, includes a washer 38 disposed about the upper end of the valve member 33, the valve guide 34 and a notch 39 provided in the valve member 33.
  • a pull chain 40 is employed, one end of which is connected to ring 41 attached to the upper end of the valve member 33 and the other end of which is detachably connected to the handle 11.
  • a coil spring 43 surrounds the valve member 33 within the tank 20, one end of which bears against a washer or disk 42 fixed to the valve member 33 and the opposite end of which bears against the lower end of the valve guide 34.
  • the spring 43 normally holds the valve 33 in its seated or closed position.
  • a pull on the chain 40 raises the valve member 33 against the tension of the spring 43, thus opening the valve.
  • the notch 39 is raised to provide a communicating passage between the atmosphere and the interior of the tank, and the wax or other floor-treating material in the tank will then slowly flow through the discharge opening 35.
  • the nearest point of the disk 14 to the discharge opening 35 is a region in the path of rotation of the disk at which the latter moves clockwise in the direction of the arrow towards the adjacent disk 15.
  • an imaginary line drawn tangent to disk 14 will intersect disk 15.
  • the discharge opening 35 is located between a first vertical hypothetical plane which passes through the vertical center of disk 14 and is parallel to the handle 11, and a second vertical plane which is parallel to the first plane and tangential to the part of the brush connected to the disk 15 that faces the center of the polisher.
  • the parts of the brushes on disks 13 and 14 located between these planes tend to throw particles of the wax or treating material toward the central part of the machine and into contact with one of the other brushes. This prevents lateral discharge of th wax or other preparation from the machine and avoids splashing or scattering.
  • the rods 23, which includes intermediate portions and bent end portions, constitute elongated elements which are pivotally mounted on the vessel 20 for movement about spaced vertical axes, the outer free ends of which may serve as handles for holding the device 19.
  • the projections 24 on the vessel 2% constitute props which form the bottom arm of the C-shaped member or clamp for holding the vessel against th rubber ring 18 which essentially forms a downwardly extending skirt or side wall of the housing part 17, at the underside of which are disposed the rotatable members 13, 14 and 15.
  • the motor housing part 10 forms an upstanding part on the housing 9 which is of reduced cross-sectional area.
  • the lower end of the handle 11 is pivotally mounted for movement about a horizontal axis at the bottom portion of the upstanding housing part 10.
  • FIG. 1 it will be seen that the entire vessel 20 is located completely below the horizontal plane passing through the axis about which the handle 11 is movable. Hence, at least a major portion of the vessel 20 lies below the aforementioned horizontal plane and close to the surface being treated. Further, the vessel 20 is completely to the rear of the housing part 17 and at the immediate vicinity of the downwardly extending side wall thereof.
  • the discharge opening 35 will be located above the surface at a region which is rearward of first and second members 14 and 15 which are rotated in the same direction, the opening 35 being positioned in a vertical plane which is parallel to the vertical plane in which the handle 11 is vertically movable and intersects the rear peripheral edge of member 14 at a point at which it is moving toward a line connecting the axes of the members 14 and 15.
  • the aforementioned vertical plane in which the outlet 35 is located is disposed between the vertical plane in which the handle is vertically movable and the parallel vertical plane passing through the axis of rotation of the member 14.
  • the treating agent when the machine is being operated and moved rearwardly or toward the right in FIG. 1, in a direction which is essentially parallel to the direction in which the handle 11 extends and toward treating agent discharged on the surface through the opening 35, the treating agent will be contacted by a region of the rotating member 14 at such a point in its path of rotation that centrifugal force produced by such rotating member will be effective to cause the treating agent to be thrown from such region toward the member 15. In this way, treating agent will not be scattered away from the machine and is thrown toward the rotating members 13 and 15, the member 13 being driven in the opposite direction from the member 14 initially contacting the treating agent.
