Invention: "MAT CLEANER"
Abstract of the Disclosure A rug or mat cleaning apparatus is disclosed which is comprised of first a dry lint and dust removing section, then a water or like liquid containing vessel having an initial wash section and then a rinse section and then finally a wringer section. A mat to be cleaned is passed through a first conveying roller at a slower driving speed. Thereafter, the mat or rug enters an increased speed brush which both removes dirt and agitates the surface of the rug and beats it to knock loose undesireable dirt and like particles. In the wash section of the apparatus, alternating feed rollers and brush rollers carry the mat or rug to be cleaned. Each feed roller clamps and holds the rug to prevent slipping while conveying it at a slower linear speed. Each brush roller provides a brushing surface having a substantially higher linear speed than the surface of the conveying rolls. Thus, a "tuck" or crease is created in the rug between each high speed roller brush and its adjacent and following slower conveying roll. A wringer is provided at the end of the apparatus to remove extraneous water from the rug after its cleansing. Pressure belts are provided above the cleaning brushes for enhanced cleaning and operation. A special beater roller with projecting ridges is also included.

3. General Discussion of the Present Invention The present invention solves the prior art problems and short comings in a simple and inexpen9ive manner. The present invention provides a cleaning apparatus which is comprised oi a plurality of rollers which convey the rug or mat to be cleaned through a cycle which first beats the mat, then washes the mat and thereafter rinses it, and then squeezes the mat to remove extraneous water. In the preferred embodiment there is provided a plurality of feed rollers which grip the mat and convey it at a slower velocity throughout its trip through the machine. Alternating between these feed rollers is a plurality of brush rollers which have a surface velocity substantially higher than the surface velocity of the feed rollers. Thus, a slipping effect is produced between the surface of the brush rollers and ~he conveying rollers. This slipping effect urges the rug into a tuck or creased position when the rug passes from a brush roller to a feed roller. This differential speed and urging effect creates a crease or bunching up of the rug, the crease or bunching up of the rug, preferably occuring in the mat which contains the dirt retaining fiber. Thus, the fiber is flexed to expose the dirt therewithin. At the time the crease exposes the dirt, the crease and dirt are being beaten and cleansed by the roller brushes which are proximate-ly located thereto and in the washing water. This combination provides an improved cleaning effect which effectively and efficiently cleanses the dirty mats.
In addition pressure belts preferably are included locat-ed above the cleaning brushes to enhance the cleaning action, and, the over-all operation of the machine. The preferred embodiment also includes a special beater roller with project-ing axial ridges for initially~beating out dust and lint.

~ :1784~7 Brief Description of the Drawlng9 For a urther understanding o the nature and objects of the present invention, reference should be had to the following detailed description, taken in conjunction with the accompanying drawings, in which like parts are given like reference numerals and wherein:
Figure l is a perspective view of the preferred embodiment of the present invention with part of the near wall thereof partially cut away to show some of the internal components;
Figure 2 is a side, close-up of one of the roller brush sections of the embodiment in Figure l;
Figure 3 is a side schematic view of the rotating ele-ments and sections of the embodiment of Figure l; while Figures ~ and 5 are likewise side schematic views of seclected ones of the roller elements and sections of the embodiment of Figure 1, showing the two different drive systems for the rotating elements; and Figures 6 and 7 are front and rear views, respectively, of the embodiment of Figure l.
``~ 1.1';'~07 Detailed Descriptio~ of the Preferred Embodiment Figures 1-~ show the preferred embodiment of the apparatus 10 of the present invention- In Fi~ e~ l ~ 3 t~ere can be seen an overall frame 12 whlch provides a liquid containing wash and scrubbin~ section 14 an~ a rinse section 16.
A conveyan,ce section is designated generally by the numeral 20. Conveyance section 20 is comprised generally of a plurality of rollers 31-46. With reference to Figures 1 ~3, the rollers 31-41 are driven, while rollers 42-46 are idler-' tyPe rollers having no direct driven power.
The rollers 31-46 shown in Figures 1 & 3 are cooperatively arranged to convey a rug 50 through the path shown in Figure 1.
It should be noted in Figure 1 that a rug will follow a path which produces a tuck designated by the numeral 52 at the points shown 5 in the drawing. The tuck (note Fig. 2) so produced flexes the rug 50 to expose the nap fibers more fully to the cleansing action of the brush rollers 33,~ 35, 37, and 39. The tuck is produced by the differing speeds of the rollers which will be more fully discussed hereinafter.
Rug 50 begins its trip through the cleaning apparatus 10 of the present invention where it is sandwiched between rollers 31, 46. The indication of rotary travel of rollers 31, 46 is seen in the drawings, with only roller 31 being driven, roller 46 being an idler-type roller which is in surface connection with roller 31 and thus rotates therewith.
The surface to surface contact of rollers 3L, 46 also produces a non~slip driving means which will urge rug 50 forward at a substantially constant linear speed as is desireable. The speed of rollers 31, 46 will be preset and will urge rug 50 (;`7 forward at a desired speed which can be varied depending on the type of mat 50 being cleaned, the dirt or like undesireable matter content, and like conditions.
A second set o~ rollers forming a dry beating section 13 for removing lint and dust is comprised of a beater 32 and a brush roller 33. Both beater 32 and brush 33 have a substantially higher surface speed at their peripheries than rollers 31, q6.
However, they are not in face to face contact with one another, but are independently directly driven. Note in Figures 1 & 3, the direction of rotation of rollers 32, 33 as is indicated by the curved arrows. Roller 32 is equipped with a plurality of axial, projecting ridges or arms 60 ( note Fig. 1) which sequentially hit or abut the upper surface of rug 50, thereby beating out or agitating loose dirt or like undesireable particles contained within the fiber of rug 50. The combination of this beater 32 with brush 33 acts to remove initially particles of dirt from rug 50 while it is still dry. Note that brush roller 33 is provided with a brushing surface which removes the dirt material from the surface of rug 50, which removal is substantially enhanced by the operation of beater 32.
After leaving rollers 32, 33, rug 50 enters wash section 14. Wash section 14 can be filled with any desireable cleaning solution, such as water with a suitable commercial detergent or like cleaner. If desired, the liquid within wash section 14 can be heated to enhance its cleaning properties. However, it is noted that the mechanical cleaning action of the appara~
tus 10 is so effective that heated water is seldom needed, and hence the present invention serves to conserve energy.
Within wash section 14 there is a first set of conveying rollers 34 r 45. Rollers 34, 45 are in close proximity to one anot}ler with roller 34 being driven while roller 45 is no~
independently drive, but rotates in surface to surface contact v with roller 34. Roller 45 is thus of an idler nature. However, -li7~40'7 the close surface to surface abutment of rollers 34, 45 produces a non-slip situation which positively conveyq rug 50 forw~rcl.
This is unlike the contact of rug 50 with th~ previous rollerY
32, 33 which are at a higher rate of speed at their peripheries ; than the surface of rug 50. Thus, rollers 32, 33 bruch against and slip past the surface of rug 50 since its speed through the apparatus 10 is controlled by rollers 31, 46 and rollers 34, 45.
In a like manner, brush roller 35 slips past and abuts ~0 against rug 50 as it is at a higher rate of speed and at its peripherythan the linear speed of rug 50 as it travels through the apparatus 10. A tuck 52 is produced when the rug travels between brush roller 35 and conveying rollers 36, 44. This tuck is produced by the differing peripheral speeds of rollers 36, 44 which is substantially slower than the peripheral speed of brush 35. The high speed of roller 35 tends to urge rug 50 forward and crowd it about the periphery of drive roller 36 thereby creating a tuck 52 in rug 50. This tuck exposes the fibers of the rug 50 thereby enhancing the removal of ~0 dirt therefrom.
Similar to the operation of rollers 31, 46 and rollers 34, 45, rollers 36, 44are conveying rollers which abut one another in a surface to surface arrangement and thereby control the forward linear speed of rug 50, it being substantially ~5 equal to the peripheral speed of rollers 36, 44. In the preferred embodiment, roller 36 is driven, and roller 44 abuts roller 36 in a surface to surface engagement therewith, acting il7~407 as an idler.
In the preferred embodiment, brush roll~r 37 acts in combination with conveying roll~r 38, 43 as was th~ case with the previous brush roller 35 and the previou~ conveying rollers 36, 44. This second set of brush rollers in combination with conveying rollers moving at a slower speed produces a second tuck 52 as can be seen from an inspection of Figures 1 & 3. This tuck produces a second point where the fibers of rug 50 are flared open and exposed to enhance the removal of dirt as is desireable. In a like manner, conveying rollers 38, 43 are in a surface to surface engage-ment so that rug 50 will be conveyed therethrough in a positive non-slip manner. As was the case with the previous brush rollers, brush roller 37 rotates at a higher rate of speed and has a higher peripheral speed than the speed of rug 50 as it moves through the apparatus 10. A final tuck 52 is provided in the rinse section 16. In that section there can be seen brush roller 39 which is rotated at a substantially higher rate of speed than feed roller 40, 41, and 42. Rollers 41, 42 are in a face to face,surface to surface abutting relationship, with the roller 41 being driven and roller 42 being an idler type roller. Roller 42 , which forms a wringer section 15, can be of a substantial weight to press against and abut roller 41 with some force so as to squeeze rug 50 therebetween and remove excess water therefrom.
The roller 42 includes an outer foam rubber layer 42' of for example half inch in thickness to provide a better friction surface.
In addition pressure belts preferably are included locat-ed above the cleaning brushes to enhance the cleaning action, and, the over-all operation of the machine. The preferred embodiment also includes a special beater roller with project-ing axial ridges for initially~beating out dust and lint.

Rollers 41, 42 are in a face to face,surface to surface abutting relationship, with the roller 41 being driven and roller 42 being an idler type roller. Roller 42 , which forms a wringer section 15, can be of a substantial weight to press against and abut roller 41 with some force so as to squeeze rug 50 therebetween and remove excess water therefrom.
The roller 42 includes an outer foam rubber layer 42' of for example half inch in thickness to provide a better friction surface.
4~7 As illustrated in Figure 1, a series of upper inter-dititating belts 47 are provided between the rollers 40-43, 43-44 and 44-45 which press down on the rug 50 against the lower brushes (note direction arrow 48 in Fig. 2), which further enhance the cleaning action of the machine 10. It is further noted that if a rug or mat 50 would get hung up, the upper belts 47 would cause it to merely be run back over the krushes again.
It is noted that exemplary dimensions for the machine 10 and its elements are shown in Figures 3 and 4-6 with Fig 3-7 drawn to scale. Exemplary rotational speeds for the roller elements are approximately twenty-three or twenty-four rpm for the restraining rollers 31, 34, 36, 38, 40 and 41; approximate-ly three hundred and eighty rpm for the brushes 33, 35, 37 and 39; and approximateIy seven hundred rpm for the beater brush 32, it being noted that the four beater elements 60 of beater brush would all hit the rug 50 within a~out an inch or less of travel of the-rug.
As best illustrated in Figure 3, the wall 16 a is lower than wall 16 b of the rinse section 16 which receives a flow of liquid into it, and when the flow of fluid into it creates an overflow, the overflow provides a source of additional wash water into the wash section 14 which is maintained at a lower fluid level (note phantom lines "W.L." indicating the relative levels). Appropriate drains and fluid inlet lines (generally not illustrated) are included for the wash and rinse sections 14, 16.
Because many varying and different embodiments may be within the scope of the inventive concept herein taught, and because many modifications may be made in the embodiments herein detailed in accordance with the descriptive 1~784(j7 requiremnts of the law, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense.
