Description
March 17, 1959 G. SZEKELY KNIVES v Filed June 24, 1957 INVENTOR. BY F/:7e g ev KNIVES George Szekely, 'llel Aviv, Israel, assigner of one-half to Zvi Aviezer, Tel Aviv, Israel Application .lune 24, 1957, Serial No. 667,330
Claims. (Cl. 30-283) In cutting bread or cheese it is desirable to cut each time a slice of the same thickness. For this purpose there are known knives to which is attached an abutment extending in parallel with the blade and at a certain distance therefrom serving as a guiding means, the arrangement being that with the cutting edge of the blade being applied to the top of a loaf or the like, the said abutment applies itself to the front face of the piece to be cut, thereby delimiting the distance between said front face and the cutting edge, or, in other words, the thickness of the slice.
So as to properly apply the said abutment to the front face of the piece to be cut, it is not only arranged at a distance from the blade but also at a level lower than the cutting edge. The consequence s that with the cut progressing down to the lower portion of the piece to be cut, the abutment reaches the support on which the loaf is placed earlier than the blade. rl`herefore the blade cannot cut down to the said support; the cut does not sever the slice fully from the loaf.
It is the object of the present invention to provide a knife which can be used for cutting slices, delimiting the thickness of the slice and permitting a cut down to the support on which the piece to be cut rests.
It is a further object of the invention to provide a knife by means of which the sliced cut is fully severed from the piece from which it is being cut.
It is a further object of the invention to make the attachment adjustable. 1
It is another object of the invention to make the attachment removable.
It is still another object of the invention to fix the attachment so as not to restrict the usable length of the handle of the knife.
The invention will now be described with reference to the annexed drawing showing in Fig. 1 the new device in position on a knife seen in a side elevation,
Fig. 2 is a like view showing the knife from above,
Fig. 3 is a section on line III-III of Fig. 1.
A knife having a handle 1 and a blade 2 has slid on the latter a block shaped member 3 having a flap 4 hinged thereto. The blade 2 tits between member 3 and the closed flap 4. Flap 4 is fixed to member 3 by means of a set screw 5. Block 3 is fixed in position by means of two set screws 6 bearing from above onto the back of the blade. Integral with member 3 and extending at right angle therefrom is an arm 7. To arm 7 and below the same is attached slidingly a member 8 which is firmly guided in its movement, nearer to or farther away from member 3, by a prismatic guide 9 on the upper face of member 8. The position of member 8 in relation to member 3 can be fixed at will by sliding it to and fro and fixing it by means of a set screw 10 provided in arm 7. An elongated guiding rail 11 having a plane side face 11' is connected with member 8 in such a manner that the at face 11 is directed towards the blade 2 to serve as abutment. Block-shaped member 3, flap 4, arm 7, member 8, and guide 9 in combination constitute bracket means for removably fastening the guiding rail 11 to knife blade 2. Rail 11 is of angle cross section its bottom face being slightly curved upwards. As can be seen from Fig. 1 rail 11 lies slightly below the cutting edge of icc blade 2 and, as seen in Fig. 2, in parallel therewith and distanced therefrom. The distance x between blade 2 and face 11. can be adjusted as defined above.
The connection between member 11 and member 8 is constituted by a flat springy strip 12. Strip 12 is affixed to both parts 8 and 11.
In use of a knife for cutting bread, cheese or the like the knife can easily be equipped with the new gauging means whereby, within certain limits, the blade of such knife may be of different width. After having adjusted the distance x between blade and rail face 11', this being done in accordance with the desired thickness of the slice to be cut, cutting can be performed in the well known manner.
In contradistinction to what is known the abutment does not impede the cutting and a slice of bread can be cut off fully, that is to say through to the lower face of the loaf, since when the cutting edge of the knife approaches the surface on which the loaf rests, rail 11, due to the resiliency of connection 12, will yield in upward direction and permit the cut down to the supporting surface of the loaf. When the knife is lifted-due to the elasticity of connection 12rail 11 will return into its normal position.
What I claim is:
1. A knife attachment to serve as a gage in cutting slices, comprising bracket means adapted to be removably fastened to said knife and extending laterally from said knife, and an elongated guiding rail having a guiding surface parallel to and at least partially coextensive with the blade of said knife, and a leaf spring connecting said rail to said bracket means, said leaf spring extending in a plane extending longitudinally of and perpendicular to said blade.
2. A knife attachment as set forth in claim 1 wherein said bracket means includes means for fastening said guide rail at varying distances from said knife blade.
3. A knife attachment as set forth in claim 1 wherein said bracket means comprises a member having a slot for receiving the blade of said knife, and fastening means for fixing the relative positions of said blade and of said slotted member.
4. In combination with a knife, a knife attachment to serve as a gage in cutting slices comprising bracket means including means for removably fastening said bracket means to said knife, an elongated guiding rail having a guiding surface parallel to and at least partially coextensive with the blade of said knife, and a leaf spring interposed as a connecting member between said guiding rail and said bracket means.
5. An attachment for knives to serve as a gauge in cutting slices, comprising a slotted member to be slid on the blade of a knife, a set screw extending into the slot of said member to x said member on said knife blade, a lateral arm extending from said slotted member, a slide movable on said arm away from said slot, and a guide rail having a guiding surface parallel to said knife blade, said guide rail being connected tixedly and resiliently with said slide by a leaf spring extending in continuation of and in the longitudinal direction of said rail and being positioned so that its flat surface lies in a plane parallel to the plane of said slide.
