I, THOMAS BRADFORD, of 140 to 143, High Holborn, in the County of Middlesex,
Laundry and Diary Engineer, do hereby declare the nature of this Invention to be as
follows:-
This Invention relates to certain improvements in or applicable to the construction
of butter workers, the especial objects of the present improvements being to render
such apparatus more generally serviceable, of greater strength and more durable and
better capable of answering its intended purpose, especially in treating the butter or
other similar substance when it is in a condition more than usually hard such as in the
winter time, and to give the operator better facilities of and more power for blending
or mixing one kind of butter with another and a better command over the butter
being worked up and to attain other advantages hereinafter pointed out.
The Invention more particularly relates to certain improvements upon the class of
butter working apparatus described in the Specification of Letters Patent granted to
me, No. 502, dated 14th February, 1883.
As hitherto constructed such apparatus consisted essentially of an inclined wooden
table upon the upper edges of which a reciprocating frame can be traversed, the frame
carrying a transverse fluted roller by turning which and reciprocating the frame the
butter is worked or kneaded. In such construction the butter working roller has been
so applied as that it was free to receive considerable vertical movement in and
independently of the said reciprocating frame, it being constantly borne down by a
lancewood or other spring extending from side to side of the carriage above the said
Auted roller or in other ways exercising pressure upon the Journals of the said
fluted roller.
This construction of carriage and arrangement of spring and butter working roller
although suitable for ordinary butter possesses certain disadvantages especially when
working, the butter or other fatty substance in a hard state, and it is one of the special
objects of the present improvements to avoid and overcome these disadvantages.

page_text: To this end, according to the present improvements, the said spring is wholly
dispensed with, and the said roller is mounted in its end frames in such a manner as
to partake of all reciprocating and other movements the said end frames receive, but
to have no independent vertical movement therein.
In carrying out the present improvements, opposite end frames for carrying the
said fluted roller are separately moulded and cast entire in any suitable metal, together
with boxes and bearings for the vertical and horizontal runner wheels by which the
carriage is guided in side grooves of the said table, and together with rearward
extensions. These extensions of the said opposite frames are rigidly connected
together by cross bars or rods which serve as handles by which the roller and carriage
can be traversed as required, and which are completely out of the way of the roller
and are so disposed as that the butter can be freely worked without let or hindrance
and in full view of the operator.
The forward vertical runner wheels are preferably made of a somewhat less diameter
than the back vertical runner wheels for the purpose of permitting of a desirable
canting or rising movement of the front of the carriage, so that the butter may be
the more easily worked in under the fluted roller.
This improved construction permits of the apparatus being advantageously used
however hard the butter or other substance may be without any detriment to the
apparatus, and which could not well be effected in such apparatus as hitherto
constructed, and I therefore also make the said inclined table of a sufficient strength
to meet the altered requirements; and I also fit the fluted roller so that it can be
worked by a winch handle at one or both ends of the roller, thereby insuring
sufficient power to overcome the resistance of such hard butter or other substance,
whilst avoiding the otherwise very objectionable necessity of geared wheels for
obtaining such power as is required; and thus attains a sufficiency of strength in a
butter working or mixing machine of a light and portable construction.

page_text: I, THOMAS BRADFORD, of 140 to 143, High Holborn, in the County of Middlesex,
Laundry and Dairy 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 certain improvements in or applicable to the construction
of butter workers, the especial objects of the present improvements being to render
such apparatus more generally serviceable, of greater strength and more durable,
and better capable of answering its intended purpose, especially in treating the butter
or other similar substance when it is in a condition more than usually hard such
as in the winter time, and to give the operator better facilities of and more power
for blending or mixing one kind of butter with another and a better command over
the butter being worked up, and to attain other advantages hereinafter pointed out.
The Invention more particularly relates to certain improvements upon the class of
butter working apparatus described in the Specification of Letters Patent granted
to me, No. 802, dated 14th February, 1883.
As hitherto constructed such apparatus consisted essentially of an inclined wooden
table upon the upper edges of which a reciprocating frame can be traversed, the
frame carrying a transverse fluted roller by turning which and reciprocating the
frame the butter is worked or kneaded. In such construction the butter working
roller has been so applied as that it was free to receive considerable vertical move-
ment in and independently of the said reciprocating frame, it being constantly borne
down by a lancewood or other spring extending from side to side of the carriage
above the said fluted roller or in other ways exercising pressure upon the Journals of
the said fluted roller.
This construction of carriage and arrangement of spring and butter-working roller
although suitable for ordinary butter possesses certain disadvantages especially when
working the butter or other fatty substance in a hard state, and it is one of the
special objects of the present improvements to avoid and overcome these disadvan-
tages. To this end, according to the present improvements, the said spring is wholly
dispensed with, and the said roller is mounted in its end frames in such a manner
as to partake of all reciprocating and other movements the said end frames receive,
but to have no independent vertical movement therein.
The present improvements are illustrated on the accompanying two sheets of
Drawings in side elevation in Fig. 1; and in transverse section in Fig. 2; Fig. 3.
represents a transverse section of the Complete apparatus showing it in its inclined
position for use.
In carrying out the present improvements, opposite end frames, I, for carrying the
said fluted roller are separately moulded and cast entire in any suitable metal,

together with boxed or unenclosed hearings, 2, 3, for the horizontal and vertical
runner wheels, 4, 5, and 5×, by which the entire carriage is guided in side grooves, 6,
of the butter working table, 7, and together with rearward extensions, 8.
extensions, 8, of the opposite frames, 1, are rigidly connected together by one or
more cross bars or rods, 9, which serve as handles by which the carriage and butter-
working roller, 10, can be traversed as required, and are completely out of the way
of the roller, and are so disposed as that the butter can be freely worked without let
or hindrance and in full view of the operator, which is a very great advantage the
previously existing construction of apparatus did not possess. The axle, 11, of the
roller, 10, works in the bearings, 13, in the opposite frames 1, and partakes of all
movements thereof, and can be rotated backwards and forwards therein by a
handle, 12.
The forward vertical runner wheels 5*, are preferably made of a somewhat less
diameter than the back vertical runner wheels, 5, for the purpose of permitting of a
desirable canting or rising movement of the front of the roller carriage, so that the
butter may be the more easily worked in under the fluted roller.
This improved construction permits of the apparatus being advantageously used
however hard the butter or other substance may be, without any detriment to the
apparatus, and which could not well be effected in such apparatus as hitherto
constructed, and I therefore also make the said inclined table of a sufficient strength
to meet the altered requirements; and the fluted roller can be worked by a winch
handle at one or both ends of the roller: thereby insuring sufficient power to over-
come the resistance of such hard butter or other substance, whilst avoiding the
otherwise very objectionable necessity of geared wheels for obtaining such power as is
required; and thus attain a sufficiency of strength in a butter working or mixing
machine of a light and portable construction.
.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is :—
In apparatus of the class hereinbefore indicated -
1. The application of the hereinbefore described improved means of mounting the
butter working roller so as to cause it to partake of all reciprocating and other move-
ments of its carriage without having facility of independent vertical movement therein,
substantially as described.
2. The hereinbefore described improved butter working roller carriage, consisting
of opposite end frames, 1, moulded or cast in any suitable metal entire with boxed
or unenclosed bearings, 2, 3, for the horizontal and vertical runner-wheels of the
roller carriage, and with bearings, 13, for the roller spindle, the said bearings being
adapted with horizontal and vertical runner wheels, 4, 5, 5*, and the said frames
being rigidly connected by one or more cross bars, 9, substantially as described.
