This invention relates in general to a food
tendering machine and more particularly to a
6-S of Fig. 5;
Fig. '7 is a fragmentary plan View, partially in
machine for tenderizing meat, and other articles
of food, to render the same more edible and ap
petizing.
An object of this invention is to provide com
pact, safe, simple and eiiicient means for receiv
ing, and quickly and hygienically tendering and
dispensing meat and other articles of food, par
ticularly in the presence, and subject to the in 10
spection of customers.
Other objects of this invention include the pro
vision of novel means for housing or covering
such a machine and for supporting, locking and
section,V of the cutting means and mechanism for
driving the same;

pin 64’ corresponding to the pin 64. The collars
65 and 66 are each provided with a driving pin
61 which is spaced radially from and extends in
a direction parallel with that of the pins ’éfi and
54'. A washer 68 is secured to the left end of the
shaft 53 by a screw 69 which is screwed into the
internally threaded left end of this shaft. A
pinion 'In is ñxedly mounted on the collar Se and
this pinion is adapted to rotate with the collar
