Abstract

Abstract of the Disclosure A tool for cleaning dry and wet dirt has a handle carrying a piassava type brush and a rubber scraper. The handle is secured to a flange having a coaxial extension fitting through an oblique hole in the brush head. The extension projects from the underside and is fitted with a wedge fastener. The rubber scraper is carried by an angled plate secured to the top of the brush head. This plate is apertured and notched and engages in a non-rotatable manner with the flange extension.

Description

3'~

It is well known to use brushes of plassava type to clear dry dirt, such as, snow, sand, earth, glass splinters etc.
off pavements and shopfloors for example. It is also well known to use the above mentioned brushe~ or rakes made of metal or metal with rubber plates for the clearing of wet dirt, such as manure from the floors of barns and pigsties.
The above mentioned brushed of piassava type, usually referred to as piassava-brooms, usually consist of a flat, rec-tangular wooden brush head whichis set wlth the bristles of piassava type, and the wooden brush head is, in its middle, provided with an oblique handle hole at a right angle to its length in which a handle shaft made of wood is inserted. When `
the brush is used for clearing wet dirt, the handle draws this towards itself around the end of the handle shaft and will soon become rotten as well as the wood around the handel hole. This often happens before the brush bristles are worn out, whereby both brush and handle have to be thrown away sooner than necessary.
Neither has there been a satisfactory implement which could combine all the above mentioned cleaning elements. I~hen one had to perform the diEferent types of cleaning operations, one has had to use two or three different tools.
The present invention provides a cleaning tool which can be used for clearing dry and wet dirt and is of a construction `
whereby the brush will not need to be thrown away until the bristles are worn out and can then easily be replaced by a new one.
According to the inventlon there is provided a cleaning tool comprising an elongate handle secured to a flat-topped wooden brush head, the handle or a separate holder therefor having a flange which lies at an angle to the plane normal to the axis of the handle, the flange having a spigot-form extension portion which extends through and projects from a correspondingly angled ho~e ,, 1. ~

. , .. -, . ~ ~

in the brush head, a wedge which is driven into a slot in the projecting portion of the spigot-form extension as as to fix the brush head to bear against the flange, and a plate secured between the flange and brush head, the plate supporting a squeegee-type scraper and having a hole ~or the spigot-form extension nnd at least one notch which opens into said ho~e and co-operates ~ith a tapering ridge on the spigot-form extension, which ridge serves to prevent angular movement of the brush head and plate relatively to the splgot-form extension.

: lO In the accompanying drawings, which show, by way of exa~ple, one embodiment of the invention:
Figure 1 shows in plan view one form of a tool constructed in accordance with the invention;
Figure 2 shows the same tool in section along the line II-II in Figure l;
Figure 3 shows a part of a squeegee strip of the tool shown in Figures l snd 2 and Figure 4 shows a flange~ sean from underneath, of the tool shown in Figures l and 2.

Referring to the drawings, a cleaning tool has a shaft handle 1 provided with a circular flange 3 at its lower end, and the flange is rigidly fastened onto the handle 1, it being arranged that the angle of the handle l towards the flange 3 is the same as the angle a hole, for the handle, in a wooden brush head 4 of a piassava brush 2 makes to a flat top of the wooden brush head 4.
~ The flange 3 is, on the side which is presented away from the handle 1, ; provided with a projecting spigot-form extension 5 which is so arranged and dimensioned as to extend through the handle hole and to proturde between brush bristles 16 on the underside of the wooden brush head 4. The projecting part of the extension 5 is provided with an axial, diametrical slot 18 which is designed to accommodate a wedge 6 which can fix the wooden brush head 4 to bear against the

2.

..

~0~3~3~3 underside of the flange 3. The wedge 6 is preferably provided with teeth 15 on lts side that lies against the wooden brush head 4, and the teeth 15 are adapted to dlg into the wooden brush head 4 when the wedge 6 is driven into place there~y to prevent the wedge 6 from becoming loose and falling out. The extension 5 is provided with at least one, and preferably two, wedge-shaped, sharp-edged radial ridges 13 rigidly colmected at the upper end with f]ange 3 and preferably diametrically arranged. The ridges 13 extend longitudinally along, and radially outwardly from, the extension 5 and are designed to cut into the sides of the handle hole in the wooden brush head 4 when the wedge 6 is driven into ~ -place, thereby to prevent the brush 2 from turning in relation to the flange 3.
There is arranged, between the flange 3 and the wooden brush head 4, a rectangular plate 7 which is provided with V-shaped notches co-operating with the ridges 13 to key the plate to the.
extension 5. This plate 7, along the lower long edge of the wooden brush head 4, is provided with a pro~ecting portion 8 which is preferably bent downwards so that said portion 8, together with the main part of the plate 7, makes an angle of 130- 165, preferably 145. Alongside the free edge of this projecting portion 8 there is a metal strip 9 which is so arranged as to be clamped against - and maintained against a rubber squeegee strip 11, by, for example, clamping screws 10 and wing nuts 17.
This strip 11 is preferably provided, opposite the heads - of the screws 10, with open rectangular slots 12 extending from its upper longitudinal side.
It has proved advantageous to provide the plate 7 with protruding teeth 14 along one of its short sides.

The tool is used in the followingway:

lQ'~ 3~
To clean dry dirt off pavements, outside staircases, etc.
ie is advisable to use the piassava brush 2 in the normal way. The wedge 6 holds the brush 2 in a fixed position and ~hereby good cleaning results are obtained.
To clean away wet dirt, it is ndvisable to turn the tool ~o thnt the squeegee-like portiom which includes the rubber strip 11 is facing downwards and, when most of tlle dirt is cleared away, to continue with the brush 2.
When clearing away snow, it is advisable to start with the rubber strip 11 and then continue with the brush 2. If the snow is packed or if there is ice, it would be best to start cutting up the ice and the snow by means of the teeth 14.
When cleaning manure in barns, it would be best to start with the rubber strip 11 and when necessary continue with the brush 2.
