Improvements in or applicable to Apparatus for Working Butter
and the like.
I, THOMAS BRADFORD, of High Holborn, in the County of London, Dairy Engineer,
do hereby declare the nature of my said invention, to be as follows:-
This invention relates to the construction of that class of apparatus for working
butter and the like in which the washing, working and salting of the butter or other
material, is effected by the aid of suitably formed rollers which are caused to reciprocato
over a longitudinal table or trough.
In such apparatus, as hitherto constructed, the table has been made with a flat
bottom or working surface, and has been tilted or inclined both longitudinally and
transversely so that one corner of such bottom or working surface is situated below
all the others for the draining away of the butter-milk, whey, water and other moisture
worked out of or expressed from the butter under treatment; and the rollers have
been made with parallel longitudinal or surrounding circumferential grooves and have
been reciprocated solely by hand.
This invention consists firstly in making the butter working table or board of an
arched or bridge-like formation or of an analogous double inclined formation in the
direction of its length, and in arranging it horizontally in the direction of its
width, as distinguished from the aforesaid flat formation and inclined disposition in
which it has hitherto been formed and applied, the centre of the length of the improved
board being highest and the ends thereof being lowest and proferably in common level.
By such improved formation the butter can be more quickly and the better worked as
it can be kept upon the comparatively high and dry part of the board or table and the
expressed butter-milk, whey, water or moisture can more quickly drain away
towards both end parts of the table which are or may be adapted with fixed or
removable ends perforated with openings or otherwise adapted to permit of the escape
of the accumulating liquid matter.
The invention further relates to the improved formation of the rollers to be used
with such improved butter working table or trough; and such part of the invention
consists in forming the rollers with circumferential ridges and intervening grooves
helically disposed at any suitable pitch, so as to be effective in channelling the
butter in the direction of the fall of the table and at a slight inclination to the
longitudinal axis thereof, so as to aid in causing the quick escape of the butter-
milk, whey, water or moisture, and on being reversely rotated to a small extent
and reversely moved up the inclined bed of the table to be effective in re-rolling the
butter into a lump suitable for re-working, and so on; thus overcoming the defects
inherent to the rollers made with parallel longitudinal or surrounding circumferential
grooves when applied to tables or troughs of the aforesaid formation.
The rollers are mounted in suitable side bearings applied to the sides of the table or
trough in a usual manner, but are formed with a centrally disposed cross bar or handle
which permits of the roller being freely used either way without the liability of the
lumped butter or material rising into contact with the hand.
In such apparatus of larger size than can conveniently be actuated by hand I also
propose to apply a suitable arrangement of means for reciprocating the roller by
power.

Improvements in or applicable to Apparatus for Working Butter
and the like.
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 the construction of that class of apparatus for washing,
salting, blending and otherwise working or treating butter and the like in which the
working or treatment of the butter or other material, is effected by the aid of rollers
caused to reciprocate over a longitudinal table or trough.
In such apparatus, as hitherto constructed, the table has been made with a flat
bottom or working surface and has been tilted or inclined both longitudinally and
transversely so that one of its corners is situated below all the othors for the
draining away of the buttermilk, whey, water or other moisture worked out of or
expressed from the material under treatment; and the rollers have been made with
parallel longitudinal or surrounding circumferential grooves.
This invention consists firstly in making the butter-working table of an arched or
bridge-like formation or of an equivalent donble inclined formation in the direction
of its length, and in arranging it horizontally in the direction of its width, as dis-
tinguished from the aforesaid flat formation and inclined disposition, the centre of the
length of the table being arranged highest and the ends thereof lowest and preferably
in common level. By such improved formation the butter can be more quickly and
the better worked, as it can be kept upon the comparatively high and dry part of the
table, and the expressed liquid can more quickly drain away towards both ends of the
table, which are adapted with fixed or removable ends perforated with plugged openings
adapted to permit of the escape of the expressed liquid.
The invention further relates to the improved formation of the rollers to be used
with such improved butter working table; and such part of the invention consists in
forming the rollers with circumferential ridges and intervening grooves helically
disposed at any suitable pitch, so as to be effective in channelling the butter in the
direction of the fall of the table and at a slight inclination to the longitudinal axis
theroof so as to aid in causing the quick escape of the aforesaid liquid, and on being
reversely rotated to a small extent and reversely moved up the inclined bed of the
table to be effective in re-rolling the butter into a lump suitable for re-working and
so on.
The accompanying drawings represent butter working apparatus constructed in
accordance with the aforesaid improvements.
Fig. 1, represents a perspective view of a very simple modification.
Fig. 2, represents a like view of the apparatus illustrated in detail in Figs. 3 to 5,
the roller and its carriage being removed.
Fig. 3, represents a side elevation partly in section.
Fig. 4, represents an end elevation partly in section, and
Fig. 5, represents an end elevation of the roller-carriage reprosented in Figs. 3
and 4.
6, represents the improved helically formed butter-working roller. In the modifi-
cation represented in Fig. 1, the roller 6, is mounted on a through spindle 7, which is
fitted with end handles 8, by which the roller is rolled over the arched butter-working
table 9, parts of the spindle 7, between the ends of the roller and the handles being
adapted to rest on the arched sides 10, of the table. When not in use such roller is
supported by stay bars 11, connecting the supporting legs 12.
In the modification represented in Figs. 2 to 5; the spindle of the roller is repre-
sented as supported by a carriage consisting of side frames 13, connected by a top
handle 14, and adapted with runners 15, and 16, the former of which enter arched
grooves 17, made in the outer part of the sides 10), of the table 9, and the latter of

page_text: which runners work against projecting parts 18, of such sides 10. The runners 15,
and 16, thus co-act with the sides of the table 9, in causing the roller 6, to traverse
over the arched table equidistant therefrom at all parts and without frictional contact
with the inner part of the sides 10, thereof. The runners, 15, are carried by screw
pins 19, which are secured to the frames 13, by screw nuts 20, and the runners 16,
are carried by bearings 21, which project from such frame. The frames 13, are
formed with inclined slots 22, which permit of the spindle 7, being readily placed in
and removed from the carriage. The spindle is provided with a handle 24, by which
the roller 6, can be rotated simultaneously with the traverse of its carriage over the
bed of the table by the handle 14;-when in use the spindle is kept in position in the
grooves 22, by pins 23.
The side grooves 17, are open at the ends, which permits of the roller-carriage (when
in the position represented in full lines in Fig. 3) being removed from the table by
raising the outermost rollers 15, in the direction of the arrow X, and then withdrawing
the other rollers 15, from out of the grooves 17, and when thus removed, the carriage,
roller and its attachments are placed on under-supports 11, out of the way of the
operator and yet handy for use, as represented by the dotted lines in Fig. 3. These
supports are provided with projections 25, which prevent the carriage from rolling off
the supports, 11. When thus removed, a butter-making board 26, can be placed in a
horizontal position, on the highest one of the ends 27, of the table, such board being fitted
with under-projections 28, respectively adapted to fit on each side of the raised end 27
and against the inner part of the sides 10, of the table, when the butter can be made
up as indicated by the dotted lines in Fig. 2.
The bed 9, of the table is, as aforesaid, made of an arched or segmental forma-
tion (or it may be made of a double inclined formation as represented by the
peculiarly dotted lines in Fig. 3) the highest part being at the centre of its length, or
thereabouts, and the ends being, as aforesaid, practically at the same lower level.
Such formation of the bed of the table is preferably made by planing or turning the
top edge of flat boards to the required formation, vide Fig. 3, but it may be otherwise
made. At the lowest parts of the table 9, adjacent to the ends 27, through-
apertures 29, are made for the rearly escape of the expressed liquid, these apertures are,
at other times, closed by removable plugs, 30.
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 :-
1. The formation of butter-working tables of an arched or double inclined
formation adapted to operate substantially in the manner hereinbefore described.
2. The formation of butter-working rollers adapted to be used with such butter
working tables, with helically disposed projections and grooves adapted to operate
substantially in the manner hereinbefore described.
3. In combination, in butter-working apparatus, a butter-working table formed of
an arched or double inclined formation, and a roller formed of a helical formation
when adapted to co-operate substantially in the manner hereinbefore described.
