Improvements in and relating to Butter Molds.
We, ALBERT L KINNAMON, Barber, and WILLIAM STEWART DEAN, Merchant, both
residing at Sauk Centre, in the County of Stearns, and State of Minnesota, one of the
United States of America, 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 butter molds, and has for its object the construction of a
device for removing such substances as butter, lard, oleomargereen etc. from firkins,
jars and like packages, in pieces of any required size and weight, as prints of one-
fourth, one-half, or one pound, or more or less, without the necessity of weighing the
same.
Different sized molds will be provided for different sizes of prints as each mold is
designed for a particular quantity; thus a one-fourth pound mold will cut a one-fourth
Or each size mold can be
pound print only, and so on with each size of mold.
provided with different shaped knives so as to increase or decrease the amount of
butter or other commodity in print, retaining the same size plate, B.
The improvement consists of the novel features which will be hereinafter more
fully described and claimed, and which are shown in the annexed drawing, in
which:
Figure 1, is a perspective view, parts being broken away of a butter-mold embodying
our invention;
Figure 2, is a side view, parts being broken away, of the mold showing its operation
by dotted lines ;
Figure 3, is a top plan view of the plate, the handle operating rod and intermediate
links being removed;
Figure 4, is a cross-section of the knives on the line, Y. Y; of Figure 1, on an
enlarged scales;
Figure 5, is a detail view of one end of the plate.
The stock, A, is tubular, and is provided with the handle, C, and at its lower end
with the plate, B. The lower end of the stock, A, is slotted to form the branches, a, u,
between which the knives, D, and their connections with the operating rod, E, work.
The knives, D, two being provided and located diametrically opposite each other, are
similarly constructed and connected with the rod, E, hence a description of one will
suffice for both. The knife curves and its shank, d, is pivotally connected with the
plate, B, as shown, the curvature of the knife being on the arc of a circle having
its center co-incident with the pivotal connection of the shank, d, with the plate, B.
The links, e, connect the knives D, with the lower end of the rod, E, and are
pivotally connected at their ends with the knives and said rod, respectively, sub-
stantially as shown. The shanks, d, are of a less width than the knives so that they can
work on the plate, B, when the rod, E, is depressed to project the said knives below
the plate. The edges of the plate, B, are recessed at, b, as shown in Figure 5, to
receive the knives so that the latter may come flush with the edges of the said
plate. The scrapers, G, spanning the recesses, b, clean the knives when the latter
are drawn up to release the print. The operating rod, E, works through the
stock, A, and has a knob, F, on its upper end to be grasped when moving the
said rod, E.
The operation of the device is as follows:
The plate, B, is placed on the butter or other like commodity and pressed upon
sufficiently to leave the imprint thereof on the butter. The operating rod is
pressed down and forces the knives into the butter, the knives being long enough
to meet below the plate, as shown in Figure 2. The stock is turned half-way
around in either direction as the knives are double edged, separating the print

page_text: which is removed by lifting the mold. The print is discharged by withdrawing
the rod, E, which retracts the knives, as shown by dotted lines in Figure 2.
After a layer of the substance is removed the surface of the next layer is smoothed
by using the mold as a patter.
The spring,, K, secured to the handle, C, at one end, bears on the rod, E, at
its other end to hold the same from slipping.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is-
1. The combination, with the stock having the plate B, at its lower end, and the
curved knife having a shank which shank is pivotally connected with the plate of
the operating rod and the link pivotally connected with the said knife and the
red, substantially as and for the purpose described.
2. In a butter mold and cutter, the combination of the stock having plate, B,
the curved knives having shanks, which shanks extend in opposite directions and
are pivotally connected with the said head, the operating rod connected with the
knife shanks opposite their pivotal ends and the scrapers, G, spanning the said
knives, substantially as and for the purpose described.
3. The combination with the stock slotted at its lower end and having a head,
and the curved knives having shanks which have pivotal connection with the
head, the operating rod and the links pivotally connecting the knives with the
said rod, substantially as described.
4. The combination with the stock, the cutting knives and the operating rod
connected with the knives, of the spring secured at one end to the stock and
having its free end pressing laterally on the operating rod to sustain it and the
knives, substantially as and for the purpose set forth.
5. The hereinbefore described butter mold comprising the tubular stock, A,
slotted at its lower end, and having the plate, B, and the handle, C, the curved
knives having shanks, d, which shanks are pivotally connected with the plate and
are of a less width than the knives, the operating rod, the links pivotally
connecting the knives with the said rod, the scrapers, G, and the spring, K,
substantially as specified.
