POLISHING MACHINE HAVING RESILIENT MOUNT FOR AEROSOL DISPENSER Filed Nov. 4, 1960 67 INVENTOR. |'L|P RACHLIN ATTORNEY United States Patent 3,071 792 POLISHING MACHINE HAVING RESILIENT MDUNT FOR AERGSOL DISPENSER Philip Rachlin, Havertown, Pa, assignor to Eastern Research Corporation, Philadelphia, Pa., a corporation of Pennsylvania Filed Nov. 4, 1966, Ser. No. 67,281 8 Claims. (Cl. 15-50) This invention relates to a polishing machine having an aerosol dispenser thereon. More particularly, this invention relates to a polishing machine having an aerosol container of a wax finishing agent resiliently mounted thereon and a nozzle means for selectively dispensing a wax finishing agent onto .a floor adjacent the polishing machine in the form of an aerosolized foam.

The present invention is a continuation-in-part of my copending application Serial No. 38,573, filed on June 24, 1960, and entitled Polishing Machine With Aerosol Dispenser.

It has been found desirable to provide a polishing machine with a container of a wax finishing agent which can be selectively dispensed onto the floor adjacent the polishing machine in a manner which does not interfere with the careful manipulation of the machine by the operator. The polishing machine should be provided with a container of wax which will enable the machine to remove scuff marks and dispense the wax on a portion of the floor to be polished while the adjacent portion of the floor is being polished. The Wax should be of a nature so that it dries immediately thereby enabling the floors in congested buildings such as department stores, railroad stations, office buildings, etc. to be polished while the buildings are being used. Heretofore, it has been conventional to clean and polish floors in congested buildings during the evening hours so .as not to interfere with the activities being carried on within these buildings.

It is desirable to provide a cleaning and polishing all purpose wax so that a floor may be cleaned and polished simultaneously. In addition, the wax should be of such av nature so that the polishing machine will provide a continuous film of wax on the floor instead of a series of minute spots. The wax should be provided within a container so that it may be dispensed with a minimum of effort on the part of the operator of the polishing machine.

It is an object of the present invention to provide a novel polishing machine having an aerosol dispenser resiliently mounted thereon.

It is another object of the present invention to provide a polishing machine with an aerosol dispenser which takes advantage of the vibratory motion generated by a motor on said machine.

It is another object of the present invention to provide a polishing machine with an aerosol dispenser capable of dispensing wax in the form of aerosolized foam.

vIt is still another object of the present invention to provide a polishing machine with an aerosol dispenser having a nozzle positioned at a remote point from the container for the floor finishing agent being dispensed.

Other objects will appear hereinafter.

For the purpose of illustrating the invention there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

FIGURE 1 is a perspective view of the floor polishing machine of the present invention.

FIGURE 2 is a fragmentary view of the handle and aerosol dispenser of the present invention.

FIGURE 3 is a transverse sectional view taken along the lines 3-3 in FIGURE 2.

FIGURE 4 is a sectional view taken on line 4-4 of FIGURE .2.

Referring to the drawing in detail, wherein like numerals indicate like elements, there is shown in FIGURE 1 a polishing machine designated generally as 10.

The polishing machine 10 comprises a brush housing 12 which supports an electric motor 14 on its upper surface. The motor 14 is provided with a drive shaft (not shown) connected to a circular brush 16 for rotatably driving the same in a manner, per se, well known in the art. The brush 16 is disposed on top of a pad 18, said pad lying on the floor to be cleaned and polished.

A shaft 2! is connected to a boss 22 on the brush housing 12 by a pivot pin 24. The end of the shaft 20 remote from the brush housing 12 is provided with a T-shaped handle 26. The handle 26 is provided with a switch button 28. The switch button 28 is connected to a switch (not shown) within the handle 26 and said switch is connected to the motor 14 by wires 30 which extend through the shaft 20.

A sealed pressurized aerosol container 32 is mounted on the shaft 20 adjacent the handle 26 by a pair of clamps 34. The clamps 34 are made from an elastomeric material for a purpose to be made clear hereinafter. As shown more clearly in FIGURE 3, the clamps 34 comprise an annular ring 36 having a channel 38 and a U- shaped clamp 40 integral therewith by means of the thick web 42. The portion 44 of the ring 36 which is diametrically opposite the web 42 has a thickness substantially less than the thickness of the ring 36 adjacent the web 42. The

arms

46 and 48 of the U-shaped clamp 40 extend around the shaft 20 and are fixedly secured together by the bolt 50. The bolt 50 is threaded and the head thereof is juxtaposed to one surface on the arm 46 and a nut 51 is juxtaposed to the arm 48.

The aerosol container 32 is provided with a wax solution dissolved in Freon 12 under eighty pounds per square inch of pressure. The formula for the wax solution may be in accordance with the formula set forth in the aboveidentified copending application. All of the constituents are dissolved by the Freon 12 which is the propellant for dispensing the wax solution out of the container 32. The Freon 12 forces the wax solution up through an axially disposed pipe 52. The lower end of the pipe 52 (not shown) is disposed adjacent to but spaced from the bottom wall of the container 32. The upper end of the pipe 52 is provided with external threads on which is mounted the valve body 54. The valve body 54 is provided with a counterbore internally threaded for cooperation with the external threads on the pipe 52. The valve body 54 is provided with an axial bore extending from its upperrnost surface. The latter mentioned bore is provided with internal threads 56 threads on the valve stem 58. The valve stem 58 cooperates with'the valve body 54 to define a valving chamber 59. The valve stem 58 is provided with a radially extending handle 60 adjacent to the handle 26 for the shaft 20.

The lowermost surface of the valve stem 58 within the valving chamber 59 is provided with a resilient valve member 62. The valve member 62 cooperates with the seat defined by the angled wall 64 and the horizontal bottom wall 66 to control flow of the wax solution from at? tube 52 through the inlet port '67 in the bottom wall As seen more clearly in FIGURE 1, the valve body 54 is provided with a boss 69 having a bore in communication with the valving chamber 59. A flexible tube 70 is connected to the boss 69 and extends along the container 32 within the channels 38 to a nozzle 72 mounted on the brush housing 12. The nozzle 72 is provided with an outlet 73 directed so as to dispense the wax solution onto which matingly engage external J? the fioor adjacent the brush 16. A flexible wire extends from the uppermost clamp to the boss 69 so as to prevent strain on the hose 7i) and locate the valve body 54 when the container 32 is replaced.

The polishing machine 10 of the present invention is utilized in the following manner:

A commercially available abrasive pad 18 is disposed on a floor. The machine 10 is then disposed on the pad 18 as shown in FIGURE 1. Then the operator will plug in the electrical cord (not shown) for the motor 14 in a suitable electrical outlet. Then the operator will operate the motor 14 by actuating the switch button 23 on the handle 26. Then by digital manipulation, the operator will rotate the handle 66 on the valve stem 58 thereby 'moving the valve member 62 away from its valve seat so that a wax solution is permitted to be discharged from the container 32 by the Preon l2 propellant. The wax solution flows through the hose 70 and is discharged by the nozzle 72 onto the floor adjacent the brush housing 12 in the form of an aerosolized foam.

The machine 10 is then manipulated by the operator 'so that the pad 18 is disposed over the foam wax solution on the floor. The rotary movement of the brush 16 and pad 18 removes the old wax from the floor and polishes the floor with a continuous film of wax having a high luster. The Freon 12 which was in solution with the wax evaporates so that the rotary movement of the pad providesa continuous high luster wax film instead of a series of minute spots of high luster wax. The wax solution will dry almost immediately so that a person may walk over the newlywaxed portion of the floor. Thus, the waxing of the floor may be accomplished without interrupting the activities of persons utilizing the floor such as the customers in a department store. Scuff marks are readily removed by the abrasive pad 18 and the film of wax provided on the floor is noticeably devoid of any slippery characteristics. That is, the continuous film of wax is not slippery and does not provide a danger for those persons walking on the film immediately after being deposited. After a small portion of the floor has been polished, the handle 60 on the valve stem 58 is digitally manipulated so as to deposit a small amount of aerosolized foam wax on the floor adjacent to the polished portion. The operator will then manipulate the machine 10 so as to clean and polish the next portion of the floor. This procedure is repeated until the entire floor or a large portion thereof has been cleaned and polished. Thereafter, the pad 18 will be removed and a buffing pad will be substituted therefor. Then the operator will buff the cleaned and polished portion of the floor.

Freon 12 is substantially an unstable fluid and tends to separate from the wax. The vibration from the motor 14 is transmitted to the aerosol container 32 by the shaft 20 and the clamps 34. The clamps 34 are made of an elastomeric material so that the motor vibrations cause the container 32 to be comfortably vibrated. In actual practice, the container 32 has the appearance of a vibrating reed. The vibratory motion of the container 32 maintains the Freon 12 in solution with the Wax so as to Ob". tain the high luster on the floor and so that the Wax solution may be dispensed in the form of an aerosolized foam.

Thus, it will be seen that the present invention provides a polishing machine having an aerosol dispenser for wax or any other floor finishing agent resiliently mounted thereon. The wax or floor finishing agent is adapted to be dispensed onto a floor adjacent the brush housing 12 of the machine 10 in the form of an aerosolized foam. The machine 10 in cooperation with the pad 18 removes the dirt, scuff marks and old wax while simultaneously applying the wax foam to the floor as a continuous film of wax. Thus, the methods used heretofore involving mops, pails, etc. for cleaning floors and removing scuff marks and old wax are eliminated.

The channels 38 on the clamps 34 prevent the hose 70 t from having an uncontrolled loose position. The wire 74 prevents strain on the hose '76 and enables a new container to be located properly when the old container is empty. The clamps 34 have their greatest thickness in that portion adjacent the web 42 so as to have sufficient strength to support the weight of the container 32 while still providing a resilient mount for the container 32. The position of the container 32 may be adjusted relative to the handle 26 to suit the desires of the operator by merely adjusting the bolts 50. When a new container 32 is substituted for an empty one, the new container is inserted into the annular ring 36 on each clamp 34. The resiliency of the elastomeric material of the clamps 34 permits the annular ring 36 to be deformed temporarily for the insertion of the new container 32. The adjustability of the position of the container 32 permits the handle 60 to be adjacent to the handle 26 so that the operator may selectively dispense aerosolized foam while maintaining suilicient control over the operation of the machine 10.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.
