Improved Construction and Arrangement of Power Driving Gear for
Meat Cutters.
I THOMAS WILLIAMS the younger, of Bay Tree Cottage, Church End,
Finchley, in the County of Middlesex Engineer, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to an improved construction and arrangement of power
driving gear for meat cutters, and its object is to provide a simple and compact
power gear which can be economically and easily constructed and fitted.
According to my invention, I mount an internally toothed cog wheel upon the
axis or shaft of the meat cutter and drive the same by an internal pinion the axis
of which is carried by a suitable bearing secured to the base of the machine. I
employ internal gearing as being more compact and taking up less space than
ordinary gearing, and also because it does not require a second pinion or cog wheel
to change the direction of rotation and cause the cutter to revolve in the same
direction as the operating fly wheel or crank.
I further economize construction and facilitate fitting by dispensing with a set
screw or key for securing the said internally toothed wheel upon the axis of the
cutter, the said internally toothed wheel being simply slipped upon such axis and
held in position thereon by the before mentioned pinion.
The internally toothed wheel may be prevented from revolving upon the axis of
the cutter by making the said axis of any suitable transverse section, (square or
angular) where it enters the wheel, I prefer however the arrangement hereinafter
described with reference to and illustrated in the drawings.
In the accompanying drawings
Fig. 1 is a part sectional side elevation of a meat cutter having my improved
power driving gear applied thereto.
Fig. 2 is an end view of the driving gear on a smaller scale.
Figs. 3 and 4 illustrate the method I prefer to employ of mounting the internal
toothed wheel upon the axis of the cutter.
A. is the meat cutter and a the axis thereof. B is the internally toothed wheel
mounted upon the axis a in the following manner. The end of axis a is formed
with a flat face b and the end c¹ of the socket c is cast of corresponding shape to
receive it, the other end of socket c is of circular section and is bored out true and
central in a lathe. C is the pinion wheel mounted on the axis d carried by the
bearing e secured to the base D of the machine, and is the operating fly wheel
secured upon said axis and provided with a convenient handle g. The said pinion C
engages with the internal teeth of wheel B and by bearing on its inner face retains
it in position upon the shaft a. When the fly wheel is rotated the cutter will
obviously revolve in the same direction. The wheel B being simply slipped on
shaft a and held in place by the pinion C, the extra expense and labour involved by
the use of set screws or keys is avoided.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In a meat cutter, in combination with the axis or shaft thereof, an internally
toothed wheel B mounted thereon without set screws or keys as described,
pinion C gearing with wheel B and serving to hold the same in place upon said axis
or shaft, a bearing e for the axis of pinion C, and a crank or fly wheel secured

illustrated.
