Abstract

Appliance for working on certain surfaces of the kind consisting of a concave/convex hollow body, where the working tool proper is fixed to the circumference of the bottom of the hollow body (fig. 1) (1) or to detachable rings (fig. 3) which are pushed onto a hollow body of another shape. The working tool proper is a disc, which is sharp toward the centre, in some embodiments a ring-shaped knife with an interior cutting edge. In other embodiments scratching points or file-cuts on the bottom may be present. Fluid-containing material may be attached to the bottom of the appliance. One form of the tool is another disc-shaped knife, having cutting edges both on the inside towards the centre and on the outside away from the centre.

Description

An Appliance for Working on Various Surfaces.
The invention concerns an appliance for working on various surfaces.
The appliance is of the kind consisting of a concave and convex hollow body, (Fig. 1), which can have various angles from top to bottom of the conical or pyramidal shape.
The working tool proper of the appliance is placed on the circumference of the bottom end (1) of said body or on rings (3) which can be pushed onto the end of another form of body (Fig. 2) whereby the bottom end of the hollow body may be a vertical ring, (2) which is the termination of the bottom of the hollow body.
The said detachable ringssections (Fig 3.) may, just as the hollow body proper, (Fig. 1) without a terminating rim be equipped with various kinds of tools and additional tools (Figs. 4 and 5), which are fixed below or near the bottom of the body (1) or the ringsection for acting on various surfaces.
Different convex and concave hollow holders with scraping devices are known. US pat. 1.246.242 is a drop-shaped appliance with undulating edges. The drop-shape makes it possible for the pointed end which is the purpose of the invention. Another example, also meant for pots and pans, is US.pat. 1.718.496. Here the shape is half or part of a spherical surface. The scraper is made of metal and has sharp edges. A third US pat. 3.133.301 describes a circular lid-shaped ice scraper made of a more flexible material, which has the advantage, that the vertical, circular scraping edge can adapt to non-plane surfaces and bends. The same patent describes a scraper with a double circular ring, which may work either as a double scraper or be a holder for a detachable scraping ring.
A fourth US pat. 4.422.206 describes also an ice scraper. The shape is here part of a hollow spherical shell, which has two notches cut into it. This scraper is shown both with a long handle and in another embodiment with a short handle placed directly on top. The circumference is terminated so as to be sharp. As the two notches are cut diagonally in the shell, the scraper does not function in all 360° directions but primarily by a reciprocating motion.
ijlone of the hitherto known appliances of this kind, neither those for a single purpose or those having the possibility of fixing interchangeable tools (e.g. cutting tools) to any kind of holder, handle and shaft have a direction of pressure going from a real or virtual point at the top of a cone or pyramid directly towards the bottom edge, at the same time acting by being moved in all directions of 360° None of them have a ring-shaped knife having an interior cutting edge towards the centre.
The invention provides an appliance which, with various tools attached either to the circumference of the hollow body (1) or to the interchangeable rings, can work in all directions of 360° on a surface by just pushing or drawing it in the direction prefered. If e.g. a cutting ring (Fig. 3) with a cutting, annular disc (Fig. 3) having the cutting edge (3) on the inside towards the centre is, attached,* in addition to the 360° action, a stability with equal cutting angle is obtained, caused by the central position of the pressure point and the centre of gravity and by the surrounding support.
This support is obtained because the annular disc rests on the surface from the cutting edge and away from the centre. The pressure is evenly distributed over the bottom of the hollow body by contact with the surface being worked. An internal cutting edge (towards the centre) cannot bite into the surface, as an external edge (away from the centre) would able to do.
At the same time, the lever principle is utilized, in that the of the cutting edge (3) in the case mentioned has the length of half the circumference, while only by passing over the material, working on a width equal to the diameter, which is 66% of the real length of the edge.
Moreover, in the case described, where the cutting edge is the inner edge of an annular member, a selfsharpening effect on the edge (3) is obtained, in as much as the part of the edge opposite the working part is worn so as to keep it sharp. This applies alternatingly as the appliance is pushed or pulled in the direction preferred.
With a cutting ring attached (Fig. 3) the centre of pressure is always in front of the working part of the edge, which is pulled forward. This makes the working more stable and sure.
The appliance may be made with various diametres and different angles, when the concave/convex shape is a cone or pyramid. This will influence the direction of the forces acting on the bottom circumference of the hollow body or it's lower vertical rim for attaching tools, and must be chosen according to the di ferent applications.
The bottom allows a great pressure per unit area, according to the area of the contacting surface (Width of the annular disc) (Fig 3) which may be circular or polygonal with a greater or lesser area of contact.
The hollow body itself may in certain embodiments be more or less elliptical or even pyramidal, with various numbers of sides, the different tools fitting the shape in question of the bottom.
If the vertical termination shown as an example, these tools are fixed to the u-shaped section fitting the shape in question of the bottom. Other methods of attachment may be used.
In claim 1. is described the hollow body (Fig. 1) with the cutting tool fixed to the bottom.
For a simple or disposable appliance the vertical termination for attaching interchangeable rings with tools is not needed. The tool according to claim 1. is the disc shaped knife with the interior cutting edge (3) towards the centre. The disc-shaped knife proper may be at various angles to the surface worked at, in that the annular disc may be tilted more or less downwards towards the centre. The cutting angle may be chosen before hand (not manually adjustable) according to the work in question or the surface being treated.
Claim 2. refers to certain tooth-shaped projections, (Fig 4. (4)) required for tearing and scratching certain surfaces. The teeth (4) are used together with the annular knife (3) or alone or together with other tools. They may be placed on the bottom (not shown) and on the side as shown in Fig. 4, bent with the points against the surface to be treated. This provides a somewhat resilient effect.
Claim 3. refers to a fluid-containing material mounted on the bottom of the appliance together with a cutting edge for cleaning or washing or for application of solvents. This material may be sponge-like on in the form of a brush of hair or other fibres. This has a lubricating, dissolving or cleaning effect in connection with the scraping or cutting effect. This may be combined with claim 2. Claim 4. refers to hard, abrasive material or file-cuts arranged on the bottom surface of the appliance e.g. in connection with cutting edges.
The file-cuts may be in different executions, following the outer edge. If the appliance is provided with a cutting edge of hard material, combined with file-cuts, it can be used on metal surfaces, for which application no file or cutting tool acting in all directions and having a central handle and central application of the force exists.
Claim 5. is like claim 1. with the difference that an external cutting edge is also present. Here cutting in two directions is possible. Moreover, the two cutting edges may be at different angles to the surface to be treated.
The tools mentioned in this patent application and other possible tools may all be fixed permanently onto the circumference of the bottom of the appliance (1) without being interchangeable. According to quality of execution the appliance may be a simple tool or a cheap tool to be discarded after use.
