aecompanyfngdrawings illustrate a seitlie invention-anu thevi'e'ws 1tllieifeinllaire asfffoll Fig; rais iafeental, sectibriai view lof tnefknife shown in Fig. l;
Fig. 3 is a fragmentary, sectional view of a reinforced blank employed in forming a knife embodying thel invention; and
Fig. 4 is a yfragmentary view of the black shown in Fig. 3 after being ground to form, With original outlines of the blank indicated in dotted lines, and additional angular dotted lines indicating cutting edges resulting from regrinding from time to time.
The particular knife Il] herein disclosed for the purpose of illustrating the invention comprises a generally disk-like body II which, as shown, is of stainless steel and provided with a central, reinforcing plate I2 spot welded thereon. A central opening I3 co-axial with the body II and the plate I2 is provided for mounting the knife on a shaft of a slicing machine for rotation.
The body I`I and the plate I2 may be formed from flat disks of stainless steel which are shaped in a punch press, the plate I2 being shaped to the form shown in Fig. 2 and the body Il being shaped to provide a peripheral portion I4 of the form shown in Fig. 3 and indicated in dotted lines in Fig. 4.
Thereafter the peripheral portion I4 of the knife is hardened and then ground to the form shown in Fig. 4, the waste or ground oi portion being indicated in dotted lines in that iigure. The grinding of the peripheral portion of the body II of the blank shown in Fig. 3 is conducted to produce a portion of desired thickness, which may be of the order of .048" to .050", with opposite, preferably parallel surfaces I5 and I6, a peripheral bevel I1, and an adjacent cutting edge I8. The hardened portion of the knife, including the surfaces I5 and I6, extends inwardly from the cutting edge I8 a substantial distance to provide for repeated grinding of the cutting edge to provide new cutting edges, as indicated by the dotted angular lines in Fig. 4, With beveled portions I1 of like dimensions and angular relation with the original beveled portion.
The knife Il) thus produced is generally diskshaped with a depressed central portion I9 having opposite surfaces and 2| disposed in planes substantially normal to the axis 22 of the opening I3, intermediate portions 23 and 24 arranged in angular, radially spaced relation with the axis 22 and with one another, a peripheral portion having opposite surfaces I5 and I6 parallel with one another and disposed in angular, radially spaced relation with the axis 22 and the intermediate portions 23 and 24, and a peripheral bevel I1 disposed in angular relation with the surfaces I5 and I6 and providing a circular cutting edge I8.
'Ihe formation of a slicing knife in the manner stated, using stainless steel, enable the provision of a knife having a bevel approximately M3 wide adjacent the cutting edge and the maintenance of a bevel of like Width through successive regrinding operations until the available hardened portion of the knife, which ordinarily will extending a depth of 1%," inwardly from the cutting edge of the knife, is exhausted.
An example of a slicing knife embodying the invention which has been found satisfactory may be described as follows: A iiat disk of stainless steel 1/8 thick is centrally reinforced by welding thereon a circular plate of like material gif thick. The composite article is shaped in a punch press to generally dish form, as shown in Fig. 3, with a substantially flat central portion of approximately 3" in diameter, an adjacent, intermedi- CII ate annular portion approximately 5 wide and having an outer diameter of approximately 9%", an annular peripheral portion approximately 11/8" wide and having an outer diameter of approximately 11%", and an angular portion connecting the said peripheral portion and the said intermediate portion and having opposite surfaces arranged in parallel relation with one another and disposed at an angle of approximately 30 with the said surface of the central portion. The peripheral portion is hardened by induction. The peripheral portion and the adjacent connecting portion are then ground to the form shown in Fig. 2, providing a connecting portion having opposite, parallel surfaces spaced approximately g apart, a peripheral portion having opposite, parallel surfaces spaced approximately .050" apart and disposed at an angle of approximately 2 in relation to a plane parallel with the said surface of the central portion, and a peripheral bevel approximately 1/8" wide to provide a cutting edge at the upper surface of the said peripheral portion, viewing Fig. 2.
Changes may be made in the form, construction and arrangement of the parts without departing from the spirit of the invention, and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claim.
The invention is hereby claimed as follows:
A circular knife for meat slicing machines and the like comprising an outer peripheral thin circular rim having straight, flat, parallel sides extending in a direction perpendicular to the axis of the knife and terminating in a cutting edge, an inner integral section extending from the inner end of the rim at an angle from the plane of the rim and having parallel sides, a dish shaped central portion extending inwardly from the inner section and integral therewith, said central portion increasing in thickness toward its center, and a central circular reinforcing section fixed to the concave part of the central dish shaped portion and conforming in shape thereto and of less diameter.
