FR2492305A1 - Hand-tool for cheese cutting - uses lever system to drive cylindrical core-cutter and straight knife for cutting into segments - Google Patents

Abstract

The hand-tool is used to cut cheeses, and incorporates a lever system to drive a cylindrical cutter or a straight knife (2) with reduction of effort. The cheese may be mounted on a turntable during cutting, a light push being sufficient to rotate the work. A scale on the perimeter of the table may be used to determine the size and weight of cut segments. A cutting operation entails the removal of the core from a circular cheese, using the cylindrical cutter pinned to an intermediate point on a hand-lever with a wall-pivot. The straight knife is then used to cut the cheese into segments, its fulcrum (F) being located on an upward extension of the axis of the turntable.

Description

The invention described below relates to the slicing of pieces of cheese, of cooked cheese, large sizes.

For this kind of work, there is today, except for some very expensive machines, only the knife with two handles. The penetration of this remains difficult in the Comté or Emmenthal millstones which requires a sustained effort, repeated very often in certain points of sale where the flow is important.

The electrically controlled machines, used mainly by industrialists in the profession, specialized in vacuum packaging, do not eliminate the manipulation of the half-wheels by the user.

The manual cheese cutter according to the invention makes it possible to avoid all these drawbacks.

An articulated cylindrical knife, suspended from a bar serving as a lever, will hollow out a central part in the cheese. The rectilinear knife has only one handle and the latter at its other end is fixed on an axis integral with a frame.

On this bSti rests a circular plate rotating around the support axis of the straight knife. Four ball bearings will support this tray which will allow despite the weight of the whole cheese a pivoting presenting no difficulty. A light pressure of the left hand will trigger the circular movement of the cheese.

The device according to the invention will therefore avoid all these manipulations of quarters, or half-pieces by the seller. The whole cheese can be cut without touching it once it has been placed on the tray.

On the other hand the semi-curved position of the seller disappears and the fact of having a knife acting as a lever, the penetration resistance is considerably reduced.

As shown, the cheese slicer comprises: a wall fixing fig 1, supporting a bar serving as a lever fig 2, which lets pivot a support fig 3, on which is screwed a cylindrical knife fig 4. An axis fig 5 supports a second knife fig 6. A groove at the end of this knife allows it to be inserted or removed only when it is in a well-defined position. The axis supporting this knife is screwed onto a metal frame shown in fig 7. In this last figure we distinguish the four ball bearings (1) supporting the plate (2) which will guide the cheese. The graduations (3) surrounding the arrow (4) will allow the slices to be cut evenly.

This device after the recess in the central part allows the entire wheel to be cut. The rectilinear knife fig 6 is removed for the establishment of the cheese and the multiplication of the cuts becomes fast thanks to the lowering of this lever knife and to the very easy pivoting of the circular plate.

Claims (3)

 "Claims"  the lever system.  pressure from the seller or debtor with a reduction in effort obtained by  drique - another straight knife, both sharp under  Manual cheese cutter characterized by the fact that it includes 1 cylin knife 2. Cheese slicer according to claim 1, characterized by the displacement of the fro  mage under the knife in its raised position is provided by a push  very light enough to turn the tray supporting the cheese. 3. Cheese cutter according to claim 2, characterized in that this dispo  sitive has a peripheral graduation of the plate allowing to evaluate  more precisely the weight requested by the customer.
