Abstract

A floor machine having a floor treating head for engaging a floor and a handle connected to the head, the combination of a support, means for mounting the support on the extension together with means for mounting a pressurized can having a release nozzle thereon in the support and a lever mechanism mounted in the handle contactably with the nozzle for actuating the same to dispense the contents of the can upon the floor when the lever means is actuated.

Description

SUMMARY OF THE INVENTION

The invention relates to an improvement in floor treating machines and more particularly to a mechanism for attachment to the handle of the machine which mounts a pressurized can having a release nozzle. The mechanism also includes a lever mechanism which actuates the nozzle on the can whereby the cleaning and polishing material in the can is deposited on the floor to be treated by the action of the machine.

The mechanism is mounted on the rear side of the handle whereby the material in the pressurized can can be disposed intermittently in a controlled area behind the machine. As the machine is moved over the area to be cleaned and progressively drawn in a rearward direction by the operator proceeding in a backward direction, the material dispensed from the pressurized can is effectively picked up by the treating head of the machine. In this manner the operator is always working away from the floor area that has been freshly treated by the head T with which the material from the can C is used. The mechanism includes a construction which allows the pressurized can to be releasably mounted whereby the can may be removed and replaced.

These and other more detailed and specific objects will be disclosed in the course of the following specification, reference being had to the accompanying drawings, in which

Referring to the drawings in detail, the mechanism A is mounted on the extension in one form of the hollow handle H connected to the floor treating head T of the floor treating machine M. The mechanism A includes the pressure control rod 12 which lies within the hollow handle H with the upper end thereof extending outwardly through the hole 14 of the upper end wall 16 of the hollow handle H. The lower end of the rod 12 is formed with the offset portion 18 which is positioned in the hole 20 of one end of the first arm 22. The opposite and inner end of the arm 22 is formed with the hole 24 through which the pin 26 extends.

The numeral 28 designates a second arm the inner end of which is formed of a pair of spaced flanges 30 and 32 connected by the lower narrow wall 34. The inner ends of the flanges 30 and 32 terminate in the lever walls 36 and 38, respectively, the walls 36 and 38 being pressed together to form a single arm portion and complete the second arm 28. The outer end of arm 28 is formed with tip 37 formed at a right angle to the arm portion formed of walls 36 and 38.

The inner end of the first arm 22 is so pivotally connected to the flanges 30 and 32 that the lower edge of the arm 22 is in contact with a shoulder in the form of the narrow wall 34 of the second arm 28 when the lower edge of the arm 22 is parallel to the wall 34. Thus as the rod 12 is pushed downwardly, the first arm 22 pivots the second arm 28 with it and upwardly. With the arm 28 pivoted on the arm 22 the arm 28 may be pivoted upwardly and folded in overlying position upon the bracket 48 out of the way as shown in broken lines in FIG. 7.

Further provided is the support bracket 40 which includes the flat base 42, the base having formed on and adjacent the lower end thereof the upstanding short flange 44. The flange 44 is formed with hole 46. The numeral 48 designates a slidable bracket which includes the flat base 50 the lower end of which terminates in the lower right angle flange portion 52, the upper end terminating in the upper right angle flange portion 54. The lower end of the flange 54 terminates in the right angular foot 56 which lies in a plane parallel to the base. The upper end of the base 50 also terminates in the first extensions in the form of the spaced lugs 58 and 60 which extend outwardly therefrom in the plane of the base 50 and parallel to the foot 56. The flange 52 is formed with the hole 62 and the flange 54 is formed with the hole 64.

The bracket 40 further includes the sidewalls 66 and 68 formed along the edges thereof. Formed at the lower ends of the walls 66 and 68 are the inturned end wall portions 70 and 72. The end wall portion 70 terminates in the right angle ear 74, and the end wall portion 72 terminates in the right angle ear 76 which is disposed parallel to the ear 74. Each ear has a hole formed therethrough and through which the pin 26 extends. The end of the link 22 and the flanges 30 and 32 are positioned between the ears 74 and 76 by means of the aforementioned pin 26 and nut 78 thereon.

Further provided is the transverse retainer pin 80 which is mounted in holes extending through the walls 66 and 68 of the bracket 40, and positioned upon the foot 56 and against the flange 54. A pin 82 is provided which is positioned securely in the hole 64 of the flange 54, and extends freely through the hole 62 of the flange 52 and the hole 46 of the flange 44. Positioned on the pin 82 and between the flange 54 and the short flange 44 is the coil spring 84. The spring 84 normally urges the bracket 48 upwardly against the retainer pin 80, but the bracket is free to be moved downwardly upon the bottom 42 of bracket 40 against the action of the spring 84 as indicated by the arrow in FIG. 7.

The support bracket 40 is secured to the rear wall 86 of the hollow handle H by means of the nut-equipped bolts 88 and 90 extended through holes in the base 42 and the wall 86. The link 22 extends through the opening 92 formed in the wall 86 of the handle H.

The upper end of the support bracket 40 is formed with the upper end wall 94 from which extends an extension in the form of a second extension or lip 96 which overlies the bottom 42.

The hollow handle H also includes the front wall 87 connected by two sidewalls 89 and 91 and the end wall 16.

A conventional pressurized can of cleaning and floor treating fluid illustrated as C includes the annular lip 98 on the lower edge thereof and the annular lip 100 on the upper edge thereof. The can C also includes the conventional depressible and rotatable nozzle 102.

The device is used as follows: The can C is mounted on the handle by hooking the lower lip 98 of the can under the lip 96 of the bracket 40 and the upper lip 100 of the can under the lugs 58 and 60 of the slidable bracket 48. The bracket 48 is positioned so that the lips of the can will just engage under the lip 96 and the lugs 58 and 60 with a slight pressure engagement upon the flange portion 54 of slidable bracket 48 against the action of the spring 84. As a result the can C has the constant urging of the bracket 48 against the can to hold the same in clamping engagement between lip 96 and lugs 58 and 60. The can C is releasably held, for with a downward pressure upon the can the bracket may be moved downwardly against the action of the spring 84 sufficiently to allow the lip 98 of the can to be moved free and clear of the lip 96 of the bracket 40. In operating the can C the rod 12 is pushed downwardly whereby the tip 37 is moved upwardly in the direction of the arrow in FIG. 7 and against the nozzle 102, thereby depressing the nozzle whereby spray issued from the can C and upon the floor F at a point adjacent the rear of the machine as illustrated in FIGS. 3 and 4 in particular.

In the operation of the machine M the same is tilted by means of the handle H whereby the circular motion of the brush causes the machine to travel at a right angle to the direction of the tilt. The direction is reversed by tiling the machine in the opposite direction. A floor is treated by the machine M by causing the machine to travel in a path back and forth across a floor and progressively drawing the machine toward the operator after each path of travel as the operator backs up. With the spray of cleaner directed at the back of the machine it is placed in the path of the machine, for the most effective direction of travel of the machine is backwards for in moving backwardly the operator moves away from the finished floor area and thereby does not walk on the finished area of the floor. Additionally, the operator can easily observe where and how much cleaning material he is placing on the floor. The direction of the spray issuing from the can C may be varied by rotating the nozzle 102 of the can .
