PROVISIONAL SPECIFICATION.
Improvements in or applicable to Butter-working Apparatus.
I, THOMAS BRADFORD, of High Holborn, in the County of London, Dairy
Engineer, do hereby declare the nature of the said invention to be as follows:-
This invention relates to certain improvements in or applicable to the roller-
carriage and spindle of the roller of manually operated butter-working machines,
the improvements being particularly applicable to such apparatus of the nature
described in the Specifications of the following Letters Patent granted to me, to
wit: Nos. 20618 of 1889, and 2350 of 1888.
In such apparatus, as hitherto constructed, the spindle of the butter-working
roller has been made of a circular section and has been slid into horizontally
disposed slots or has been lowered into inclined slots made in the opposite frames
of the carriage, such slots having been made throughout their length of a like
width just sufficient to allow of the introduction of the roller spindle, which latter
has been secured in the said slots by pins or like removable devices or by catches
or other attachments to the machine.
All such removable devices or attachments are disadvantageous in that they are
liable to get misplaced or lost to the inconvenience of the operator and to the
liability of the spoliation of the product, and they are all subject to hard wear
which renders them liable to be quickly worn out, as, in the operation of the roller
in working the butter such pins or attached devices have to bear the greater
part of the pressure of the roller spindle.
To avoid all such disadvantages, I so construct the roller spindle and the sides
of the supporting carriage as that when the carriage and roller are applied to the
butter-working board or table and are in position for use, the roller spindle shall be
thereby caused to retain such a position relatively to the carriage as that the
latter will retain it in the slots with full facility of the apparatus being used in the
ordinary way, and as that when the carriage and roller are removed from the butter-
working-board or table, the roller spindle can be slid end wise relatively to the
carriage so as to permit of the withdrawal of the spindle and roller from the front
of the slots of its carriage.
I attain such result by making the said spindle of a circular section at such
parts as will engage with the slots or bearings of the side frames or of the carriage
when the carriage and roller are applied to the butter-making-table and in
position for use, and by making such other parts of such spindle as will be brought
into engagement with the said slots when the carriage and roller are removed from
the table and the roller spindle is slid end wise relatively to the carriage as afore-
said, of an elliptical formation or of any other equivalent formation having major
and minor axes, the former preferably not of a greater diameter than that of the
circular section of the spindle.
Also by making the said slots, preferably in a horizontal direction, with entrance
and exit channels of a width just sufficient to allow of the passage of the spindle
when so turned as to bring its minor axis at right angles to the width of the said
slots and its major axis in alignment therewith; and by making the inner or
bearing ends of such slots of a diameter just sufficient to take the major axis or
full diameter of the circular portion of the spindle, so as to allow of the same
being freely turned in the operation of the apparatus, but, as aforesaid, to prevent
the withdrawal of the roller while the carriage and roller are in position for use.
I prefer that the lower sides of the slots should be tangential to the full diameter
of the inner or bearing ends thereof so as to facilitate the withdrawal of the roller

page_text: By such means, the side frames are caused to take up all the pressure of the
roller spindle in the working of the apparatus and the necessity of any removable
parts or other attachments is avoided.
It is obvious that I can obtain the varying diameter of the roller-spindle in
various ways, either by making it of an elliptical formation at the parts aforesaid,
or by making it with two opposite flattened sides at such parts, or with one
flattened side at such parts, or by making it of a circular section of reduced
diameter at such parts or in other equivalent ways.

COMPLETE SPECIFICATION.
Improvements in or applicable to Butter-working Apparatus.
I, THOMAS BRADFORD, of High Holborn, in the County of London, Dairy
Engineer, do hereby declare the nature of the said 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 roller-
carriage and spindle of the roller of manually operated butter-working machines,
the improvements being particularly applicable to such apparatus of the nature
described in the Specifications of the following Letters Patent granted to me to
wit: Nos. 20618 of 1889, and 2350 of 1888.
In such apparatus as hitherto constructed, the spindle of the butter-working
roller has been made of a circular section and has been slid into horizontally
disposed slots, or has been lowered into inclined slots made in the opposite frames
of the carriage, such slots having been made throughout their length of a like
width just sufficient to allow of the introduction of the roller-spindle, which latter
has been secured in the slots by pins or like removable devices or by catches,
levers or other attachments to the machine.
All such removable devices or attachments are disadvantageous in that they are
liable to get misplaced or lost to the inconvenience of the operator and to the
liability of spoliation of the product, and they are all subject to hard wear which
renders them liable to be quickly worn out, as, in the operation of the roller in
working the butter, such pins or attached devices have to bear a great part of the
pressure of the roller-spindle.
On the accompanying drawings;-
Fig. 1, represents a side elevation of one of the side frames of the supporting
carriage of the butter-working-roller, formed in accordance with the present
improvements, showing the spindle of the butter-working-roller in section on the
plane a, b, Fig. 2.
Fig. 2, represents a sectional elevation of one side of the butter-working-table,
showing an end elevation of one of the said side frames and part of the butter-
working-roller.
Fig. 3, represents a section of the spindle of the butter-working-roller formed
in accordance with the present improvements, on the plane c. d. Fig. 2.
To avoid all such disadvantages as are herein before referred to, I, in accordance
with the present improvements, so construct the roller-spindle 4, and each side
frame of the supporting carriage 5, as that when the carriage and roller 6, are
applied to the butter-working-board or table 7, and are in position for use, the
roller-spindle is thereby caused to retain such a position relatively to the carriage 5,
as that the latter will retain it in the slots 8, with full facility of the apparatus
being used in the ordinary way, and as that when the carriage and roller are
removed from the butter-working-board or table the roller spindle can be slid

page_text: end wise relatively to the carriage so as to permit of the withdrawal of the spindle
and roller from the front of the slots 8, of its carriage.
1 attain such result by making the said spindle 4, of a circular section at such
parts e, as will engage with the slots or bearings 8, of the side frames of the
carriage 5, when the carriage and roller are applied to the butter-making-table and
in position for use, ride Fig. 2; and by making such other parts f, of such spindle
as will be brought into engagement with the said slots 8, when the carriage and
roller are removed from the table and the roller spindle is slid endwise, in the
direction of the arrow h, relatively to the carriage, as aforesaid, of an elliptical
formation or of any other equivalent formation having major and minor axes (vide
Fig. 3.) the former preferably not of a greater diameter than that of the circular
section of the spindle.
Also by making the said slots 8, of the roller-carriage (vide Fig. 1,) preferably
in a horizontal direction, each with an entrance and exit channel of a width just
sufficient at its narrowest part to allow of the passage of the spindle when so
turned as to bring its minor axes at right angles to the direction of entrance
into and withdrawal from the said slots and its major axis in alignment therewith;
and by making the inner or bearing ends g, of such slots of a diameter just
sufficient to take the major axis or full diameter of the circular portion of the
spindle, so as to allow of the latter being freely turned in the operation of the
apparatus, but, as aforesaid, to prevent the withdrawal of the roller while
the carriage and roller are in position for use. I prefer that the lower sides of
the slots 8, should be tangential to the full diameter of the inner or bearing ends g,
thereof so as to facilitate the withdrawal of the roller-spindle.
By such means, the side frames 5, are caused to take up all the pressure of the
roller-spindle in the working of the apparatus, and the necessity of any removable
parts or other attachments for securing the removable spindle 4, is avoided.
It is obvious that I can obtain the varying diameter of the roller-spindle in
various ways, either by making it of an elliptical formation at the parts f, aforesaid,
or by making it with two opposite flattened sides at such parts as represented in
Fig. 3; or with one flattened side at such parts, or by making it of a circular
section of reduced diameter at such parts or in other equivalent ways.
9, represents usual rollers for supporting the roller-carriage in the longitudinal
slots 10, running along the outer sides of the table 7; and 11, represents usual
rollers for laterally guiding the roller-carriage, running against the projecting top
ledges 12, of the table. 13, represents the cross-bar by which the carriage and
roller are traversed to-and-fro longitudinally of the table 7; and 14, represents
part of the winch-handle by which the roller is rotated in its bearings in the side
frames of the carriage.
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 :-
The hereinbefore described improvements in the roller-carriage and spindle of
the roller of manually operated butter-working machines.
