Improved Square Block Butter Printing Machine.
ROBERT FYPE KERR 1 Newhall Terrace Greenhead, Glasgow N.B. I do
hereby declare the nature of this invention to be as follows:-
A butter printing machine, consisting of a square metal box 8" x 8" x 3" lined
with wood, varying in proportion to the various weights of butter to be
printed. Box is fitted with brass piston moved horizontally by treadle motion, face
of piston is fitted with dovetail nut to receive carved stamp. Box is fitted with
hinged lid, fixed by quick action clamp arrangement. Piece of butter being placed
between face of piston and end of box, lid is closed and tread tramped forcing
butter into shape. To deliver butter an eccentric motion on top of lid opens clamp
releasing same, part of bottom in back of box 6" x 24" is moveable and raised by
link motion, to deliver butter when finished.

COMPLETE SPECIFICATION.
Improved Square Block Butter Printing Machine.
1, ROBERT FYFE KERR, of 1 Newhall Terrace, Greenhead, Glasgow, 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 :-
The butter printing machine consists of a square metal box, say 8" x 8" x 3" in
size, and is lined with wood. The box may be varied in size according to the
various weights of butter to be printed. The box is fitted with a, preferably,
brass piston, which is moved horizontally by a treadle motion. The face of the
piston is fitted with a dovetail nut, into which the carved stamp or print is fitted.
The box is fitted with a hinged lid, which is fastened by a quick-action clamp
arrangement.
The piece of butter is first placed in the box, between the face of the piston and
the end of the box, and the lid is then closed. When the tread is tramped, the
butter is pressed into shape. To deliver the butter the lid is opened, and a part of
the bottom of the box, which is movable, is raised up by a link motion, so as to
deliver the finished butter.
And in order that my said invention may be properly understood, I have hereunto
appended an explanatory sheet of drawings, whereon :-
Fig. 1 is a front elevation, and
Fig. 2 a vertical section of the machine.
Referring to the drawings:-
A is the wood lined box for the reception of butter to be printed. It is pre-
ferably square shaped, as shown. The box is supported on legs or feet P secured
to the stand L. B is the piston, which works in the box A, and which has a wooden
printing block B', secured to it by a dovetail nut. C is the lid of the box, which
is lined with wood, and is hinged to the box at C. E is the piston rod, which
passes out through a stuffing box E¹. The piston rod has a slot or recess E'
at its end. G is a bent lever, which is fulcrumed, at G¹, to the bracket M
secured to the underside of the box A. One end of the lever G projects up
through the slot E, whilst the other end is pinned to a link or lever N, which
is attached to the treadle F. The treadle F is hinged at F. G is a weight,
[Price 8d.]

page_text: which is suspended from a cord, attached to the link or lever N, or to the
treadle F, and which passes over the pulley O. Q is a tray for collecting any
water squeezed out of the butter, during the operation of printing. H is a drain
pipe leading from the tray. The part D of the bottom of the box A is movable
up and down by a lever S, which is connected by a pin to a lug, secured to the
lower side of the part D. The pin passes through a slot S in the lever S.
lever is fulcrumed on a shaft T, at the outer end of which is a hand-lever E³ for
⚫turning it. U is a bearing for the shaft; it is fitted on the underside of the box A.
U are guides for the part D. K is a rest for the lid C, when it is thrown back,
as shown. J is
handle, which is pivoted at J¹ to the lid. I is a spring catch
The
secured to the box A.
The action of the machine is as follows:-The butter is first placed in the
box A, and the lid C is brought down and fastened, by turning the handle J round,
so that it will be gripped and held in place by the spring catch I, immediately the
lid is closed down. The treadle F is then pressed on by the foot of the operator,
and, as a consequence, the lever N is drawn down, causing the bent lever G to be
turned, so as to force in the piston rod E and piston B, to compress the butter into
a block or "lump." The wooden print B impresses, at the saine time, a design on
the face of the block of butter. The lid is now opened, by slightly turning
the handle J, so as to free it from the spring catch, and the hand-lever E³ is pulled
towards the operator, so as to turn the lever S upwards through an arc, and so
push up the lug and part D. The forcing up of the part D lifts the block of
butter up out of the box, so that the operator can at once remove it and recharge
the box A.
The weight G2 draws back the treadle F, levers N, G, and piston B to their
original positions, ready for a new printing operation.
Any water, squeezed out of the butter during the printing operations, drops into
the tray Q and runs off into a pail through the pipe H.
The box A and its mechanism can be fitted on a table or counter.
The piston mechanism can be operated by hand, instead of by the treadle F.
The machine may be enlarged, so as to print two or more blocks of butter at
each operation.
The machine can obviously be used for printing or moulding margarine, lard and
like soft substances.
The details of construction of the machine can be obviously altered, without
departing from the principle of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The general arrangement and combination of parts of the butter printing
machine, substantially as herein before described and shown on the drawings
annexed.
2. In a butter printing machine, the combination with the butter box A, of the
printing piston B, and its actuating mechanism, substantially as hereinbefore
described and shown on the drawings annexed.
3. In a butter printing machine, the combination with the butter box A, of the
movable part D, for delivering the butter, and its actuating mechanism, substantially
as hereinbefore described and shown on the drawings annexed.
