Definitions

  • the present invention relates to an improved brushing apparatus mainly intended for use in brushing dust and other solid impurities from soft carpets.
  • the invention has for its object to overcome this difiiculty and to develop a highly efiicient brushing apparatus of a simple construction that is easily operated.
  • the invention has improved the known type of brushing apparatus consisting of a dust collecting receptacle that is movable back and forth by means of a handle, the bottom of which receptacle is provided with one or more slots or openings out of each of which one or several cylindrical-brushes partly protrude below the bottom of the receptacle, said brushes being freely rotatably journalled in the receptacle and provided with resilient bristles.
  • An object of the invention is not only to loosen one or more or all of the brushes are disposed obliquely in relation to the direction of movement of the apparatus as determined by the position of v the handle.
  • the bristles When disengaged from the carpet, the bristles are suddenly snapped back to their position of rest in a direction sidewards-backwards-upwards due to their inherent resiliency.
  • the extent and direction of this returning resilient motion of the bristles depends on the degree of the oblique position of the brush and the angle through which the brush revolves while the bristles remain in contact with the carpet. This angle depends on the relation between the diameter of the brush and the extent of the radial projection of the brush below the bottom of the receptacle.
  • Fig. 1 shows a sectional view taken along the line AB in Fig. 2 of an embodiment of a brushing apparatus according to the invention.
  • Fig. 'la is detail edge view of a brush cleaning comb.
  • Fig. 2 is a horizontal section, and
  • Fig. 3 a fragmentary plan view of the invention.
  • Figs. 4 and 5 show cross-sectional detail views in full size of two embodiments of the brush arrangement.
  • Fig. 6 shows a fragmentary horizontal section showing a modified embodiment of the brush arrangement.
  • Figs. 7 and 8 show a fragmentary cross-section and a longitudinal section respectively of a brush arrangement with further modified details.
  • Figs. 9 and 10 show similar detail views of another modified brush arrangement.
  • the brushing apparatus according to Figs.'1-3 includes a cylindrical flat receptacle I with a removable cover 15.
  • the receptacle I has a plane bottom. In the bottom of the receptacle four rectangular openings 3 are provided. In each of theseopenings a brush roller 4 is arranged being rotatably journalled in the receptacle with its axis 5 extending in the longitudinal direction of the opening.
  • the openings 3 are, inside the receptacle, surrounded ,by screens 6 and 1 projecting upwards from the bottom of the receptacle, the longitudinal screens I being inclined upwards as shown.
  • the angle of throw (with relation to the plane of the carpet) is increased when the diameter of the brushes is reduced. As the diameter is reduced, the angle through which the brush revolves while the bristles remain in contact with the carpet, increases if the bristles protrude below the, bottom of the receptacle sufliciently to penetrate into the carpet.
  • a suitable distance of projection is 3-4 mm.
  • Fig. 4 shows in full size a cross-section through shaft of the brush
  • the tool may consist of a comb H with a handle l2 punched out from a steel plate (Figs. 1 and la).
  • the handle is shaped with a hook Na in its end. The inside of this hook is sharpened. If the hook is pulled along the shaft of the brush, the threads about it are cut off withv out damaging the bristles.
  • a brush roller designed to remain in contact with r the carpet while rotating through an angle of 60. With a brush of small diameter the angle of contact may be increased to 90".
  • Fig. 5 shows in full size such an embodiment.
  • This size of the brush gives a good angle of throw so that dust may be thrown up above rather high side screens 7.
  • An angle of engagement above 120 would hardly be practical, since the brush diam.- eter would be so small that the length of the bristles would be insufficient to maintain engagement with the carpet, considering that the brushes are to have an efiicient obliq e Position of between and 65 with respect to the direction of motion of the apparatus.
  • The'brushes must have a small hub diameter, if the bristles in spite of the small brush diameter are to obtain a sutficient flexibility sidewards, which is of the greatest importance in order that the desired eiiect should be reached by the oblique position of the brushes. l'he dust delivery of the brush increases with the angle of inclination and reaches a maximum at a certain angle whereupon itbegins, to decrease at continued increase of said angle.
  • the angle, at which the maximum delivery occurs, is somewhat different for different kinds of dust.
  • the maximum efficiency is obtained at an angle of inclination of about Forsand and coarser particles the maximum efiiciency is obtained at a smaller angle of inclination.
  • Fig. 6 shows an arrangement for journalling of the brush which satisfies both therequirement of an easy rolling and protection against admission of dirt and pieces of thread and hair to the bearmg.
  • the shaft 5 of the brush roller is at both ends provided with pointed pivots 8 running in conical bearings 9.
  • the open end of eachof the bearings contains a ring of felt or other soft material 9a secured directly in the bowl of the bearing by contraction of a cylindrical collar 9b projecting from the bearing bowl.
  • the journalling on pointed pivots makes the runningof thebrush roller easy, and the felt ring protects against admission of dirt.
  • the bearings 9 are removably secured to the receptacle l. One of said bearings is not, however, secured directly to the receptacle but to a fiat spring It attached to the receptacle.
  • the handle 25 of the brushing apparatus is attached as shown in Fig. l and the best result is obtained by fastening the handle so far back that an imagined axial extension of the handle intersects.
  • the bottom of the receptacle approximately at its center, centrally between the brushes, as
  • a vertical pin it is attached to the bottom of the receptacle and is passed freely through a hole in the cover IS.
  • the cover i5 is secured to the pin by the resilient wires ll and i8. which engage a recess in .theupper part of the pin l6.
  • a hook l9 secured to the cover is lifted while the pin i6 is pressed. down.
  • the correct position of the cover and the handle in relation to the receptacle and the brushes may be secured by making the pinlG and the hole in the cover square.
  • partition walls 28-2 3 are arranged in a way to prevent the brushes from throwing, duston each other...
  • the Walls divide the receptacle into four chambers, one for each brush.
