CLEANING DEVICE Filed Sept. 17, 1953 INVENTOR ATTORNEY United States Patent C CLEANING DEVICE Titus R. Brown, Sr., Detroit, Mich.
. Application September 17, 1953, Serial No. 380,691
4 Claims. (Cl. 15-114) The present invention relates to cleaning devices and more particularly to a device for cleaning iioor coverings having a smooth surface such as linoleum.
in order to prolong the useful life and protect the ap pearance of a iloor covering such as linoleum, it is necessary that the surface be kept as clean as possible. It is a common practice to sweep such a surface with a broom having a plurality of resilient fibers. Due to the resilient nature of these fibers they remain in contact with the floor regardless of any surface irregularities However, the bers frequently fail to remove tine particles such as dust and grit which tend to adhere to the floor. Although a mop having a large number of pliable fabric members tends to pick up tine particles, it is very diicult to maintain the proper Contact between the mop and the door. Also a mop very rapidly becomes saturated with dirt to the point where its usefulness is greatly impaired.
It is proposed to provide a highly improved cleaning device which includes a frame that may be secured to the head of a broom. The frame is adapted to place a portion of a strip of cloth across the ends of the resilient fibers for wiping contact with the surface that is to be cleaned. The portion of the cloth that is in Contact with the surface will provide the desired wiping characteristics and the fibers will provide a resilient action which insures that the cloth is maintained in proper contact with the surface. Means may also be provided to facilitate advancing clean portions of the cloth across the ends of the resilient fibers.
In the one sheet of drawings:
Fig. l is a perspective view of a cleaning device that embodies the present invention.
Fig. la is a side View of the roller detent means.
Fig. 2 is a cross-sectional side elevational View taken substantially along the plane of line 2 2 of Figure l.
Referring to the drawing in more detail, a device embodying the present invention may be secured to a broom 12. The broom 12 includes a head 14 that comprises an elongated member 16 having a plurality of fibers 18 projecting from one side thereof and a handle 20 that projects or slopes upwardly from the other side thereof.l Since the handle 28 is used to operate the broom 12 it may be desirable to provide a pair ofbraces 22 thatjare diagonally disposed between the head 14 and the handle 2i) in order to reinforce the connection therebetween. The fibers 18 may comprise a plurality of resilient members that project from the under side of the head 14 so as to engage the surface to be cleaned.
The cleaning device includes a supporting framework 24 that comprises a pair of end members 26 and a plurality of links 28. The links are secured between the end members 26 and the ends of the head 14 so that the end members will be disposed adjacent the opposite ends of the head 14. The end members 26 may be provided with mounting means 30 that are positioned adjacent each end thereof. In the present instance the mounting means 38 are a pair of notches that have a riice vertical portion and'a horizontal portion whichare adapted to rotatably receive the ends of the shafts 34 and 36 on the oppositel sides of the head 14 may be substantiallyl cylindrical members'that have the shafts 34 and 36 pro-A jecting from the opposite ends thereof. Eachv of the rollers 38 and 40 is adapted to have one end' of a strip of cloth 42 or other pliable fabric material wound thereon so that the center portion 44 of the strip -will beA positioned across the ends of the resilient bers 18 so as to be in wiping contact with the surface 45 to be cleaned. Y
As the cleaning device 10 and the cloth strip 42 move across the surface, there may be a tendency for the cloth to unwind from the rollers 38 and 4t). Accordingly, it
is advisable to provide a detent for preventing the strip 42 from being accidentally unwound. In the presentinstance this comprises a cylindrical hub 46 having notches 47 adapted to receive a catch 48 on the end of spring 49. This spring 49 forces catch 48 into the notches 47 with just enough force to prevent the cloth unwindingfrom the roller 38 during normal operation.
one direction, it is only necessary to lockA the leading roller 38 as there will normally'be no tendency for the rearroller 4t) to unwind; However, if it is thought advisable, a detent may be placed on each roller.
Although any means such as a crank may be provided for winding the cloth from one roller to the other, in
the present instance a pair of enlarged discs 50 are proi vided on the rear roller 40. These discs 50 have a diameter that is larger than the roll of cloth on the roller 4 4d but small enough to normally be out of engagement with the door. When the handle is lowered to the position shown by dotted lines 52, the frame will tilt to position 54. This will cause the discs 50 to carry the weight of the broom 12. Thus as the broom moves forward the disc will rotate and wind the cloth ontoY the rear roller 48. To assist in unwinding the cloth from the the links 28m the head 14'thereof. A strip of cloth 42is then wound-onto the leading roller 38. The roller 38 is then placed in position on themounting means 30'- and the free end of the cloth 42 is threaded acrossthe ends of the resilient fibers 18 and secured to the other roller 4i). After the device.` 10, hasbeen assembled onf; the broom 1,2 it ispushed` across theysurface; 45 to be..
cleaned. As the device progresses across the surface the cloth 42 will be in wiping contact therewith and will pick up any dirt or dust. Due to the spring action of the fibers 18, the cloth 42 will be held in intimate contact with the floor 45 at all times irrespective of any irregularities that may occur therein. During this cleaning operation a considerable amount of dirt and lint will collect on the cloth 42. When the cloth 42 in contact with the surface 45 has become saturated with dirt, the operator may lower the handle 20 and tilt the frame to position 54 so as to place discs 50 in contact with the floor. If the broom is moved forward while in this position the discs 50 and belts 56 will cause clean cloth to be drawn from the front roller 38 across the fibers f isatented Apr. l, 19158 Since it is intended that the present device will only travel inV 18 onto the roller 40. The force from discs 50 engaging the floor will be great enough to cause the catch 48 to lift from the notches 47. As the dirty cloth is wound from the forward roller 38 onto the rear roller 40 any dirt that has collected on thercloth 42 will be trapped between the 'successive layers of the cloth and accordingly will be prevented from falling back onto the cleaned poor 45. Also since the cloth on the end of the resilient fibers 18 may be kept clean, a highly improved wiping action will be provided.
