This invention relates to a cutter rotatable the arms 18 and I9 are provided with kerfs or with a shaft which carries it and used ordinarily grooves 20 and 2|. These grooves are arranged for cutting meat into small particles for use as at an angle to'the plane of that side of the knife hamburg steak, and the like. carrier and bothsets of'them at the same angle,
The. principal objects of this invention are to which may be approximately 20. That is, they provide such a rotary cutter with a series of 1 slant in the direction in which the cutter is to blades fixedly but detachably secured and adjustrotate. At the back of each groove is a short able; to provide each blade with an integral pordepression 22 which can be a continuation of the tion constituting another blade so that if there groove 2| but is used'for removal of the knives, '1 are four of the first named blades, there will be as will appear hereinafter.

Each one is provided the series, and to provide these blades all at the with a sharpened edge at the outside portion, same angle to the fiat face of the hub of the both of the sharpened edges of the knives 23 and 15 cutter so that they will cut uniformly, and to. 24 being in the same plane as that of therest of 15 provide a convenient means for removing two the knives. Each knife also is provided with an blades at a time from the cutter head. opening 25 which, whenthe knife is in place, will Other objects and advantages of the invention register ith th groove 22, will appear hereinafter. It will be obvious, of course, that four of these :0 Reference is to be had to the accomp nyin double knives are insertedin the four double 20 drawing, in which grooves 20-2l so' that the cutter will assume the- Fig. 1 is a diametrical sectional view of a meat condition shown in Figs. 3 and 4.
