FRANQOIS CHARLES RICHER, OF GILMER, TEXAS.
Letters Patent No. 106,407, dated Aygust 16, 1870.
IMPROVEMENT IN COFFEE-MILLS
The Schedule referred to in these Letters Patent end making part of the same2To all whom it ny concern:
Be it known that I, FRAs9ois OHARLES RICHER,
of Gilmer, in the county of Upshur and State of
Texas, have invented a new and improved Coffee-
Mill; and I do hereby declare that the following is
a fhll, clear, and exact description thereof, which will
enable others skilled in the art to make and use the
saue, reference being had to the accompanying draw-
ing forming part of this specification.
My invention relates to upright coffee-mills, and
consists in an improved construction thereof, whereby
the beings are always maintained in their true rela-
tive position, while the strain on the two is made au-
toinatically counteracting, and each part of the shell
firmly and effectually supported by the other.
Figure 1 is a vertical section, and
Figure 2 a plan view of a doffee-mill.
A is a rotary grinder.
B, a shaft which rotates it, and
o, the crank to which power is applied.
C O' are the two parts which form the shell.
It will be perceived, from fig. I of drawing, that 0'
has three sides, b Y b, and that, on each of the two op-
posite of these a right-angled recess, f, is formed.
The part 0 is also composed of three sides, c and' d
d, but has each of the latter provided with a shoul-
der, g.
The mode of operation is as follows:
The part C of the shell being made fast to a bracket,
or any suitable support, and located in an upright po-
sition, the projecting shoulders g g are fitted snugly
into the recesses f of the part 0'.
The operator, in turning the crank a, brings a down-ward strain upon the part 0' of the shell and an up-
ward strain upon the part C. This produces a ten-
dency, in these two parts of the shell, to work in re-
verse directions, and to lose their exact and necessary
coincidence.
A very slight change of this character makes the
hearings of the shaft B non-horizontal, and throws
the grinder nearer to one side of the shell than the
other. This will produce an uneven grist, and render
the mill useless, or else necessitate arepair which will
cost nearly as much as a new coffee-mill.
Witlf the construction shown the part O' of the
shell, upon which the downward pressure is brought,
rests securely upon C, which receives the upward
pressure.
Under these circumstances the two parts of time
shell are not held merely by the attaching-pins or
sorews, but are made to counteract and counterbalance
the opposite tendencies of each other. One, there-
fore, cannot move without its companion, and the mill
will continue to grind uniformly until worn out
Having thus described all that is necessary to a
clear understanding of my invention,
What I esteem to be new, and desire to protect
by Letters Patent, is--
In an upright coffee-mill, a shell formed of two
parts, ( I f and 0 o d, applied together, as and for
the purpose specified.
