Improvements in or Applicable to the Construction of Butter
Workers.
1, THOMAS BRADFORD, of High Holborn, in the County of Middlesex, Laundry
and 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 construction
of rotating butter workers in which the butter is worked by a radially disposed
rotating fluted conical butter working roller working in a rotating circular cone-
bottomed trough supported by a vertical shaft.
In accordance with the present improvements I adapt the bottom end of the shaft
with adjustable appliances as hereinafter described by means of which it and the said
trough can be raised or lowered as required, so that the distance between the working
faces of the said roller and trough can be adjusted as and as often as required, so that
butter or other fatty substances such as margarine of greater consistency or hardness
can first be passed between the roller and trough in larger lumps or quantities, and
after being worked into thinner layers the working space between the said roller and
trough bottom can be decreased. The said adjustable means consist of a screwed
wheel or vice bar which is so applied to the shaft as to cause the raising or lowering
thereof when turned, and of a lock lever used in combination therewith and by means
of which the shaft and the said trough carried thereby can be instantly locked in
any required position of elevatiou relatively to the said roller.
The said roller and all other such working parts as the Butter Guards, the Butter
Guides and the Doffer or Clearer which removes the Butter from the Roller, are also,
in accordance with the present improvements applied to their respective bearings in
such a manner as hereinafter described as that such parts can be readily removed
therefrom for cleaning or any necessary purpose and as readily replaced in position,
and I attain such object by constructing one of the depending or other bearings by
which the said roller or other said part is supported with a sliding piece which is
formed with or analogously shaped slots, its opposite part being provided with

page_text: projecting screws and wing-nuts by means of which the removable half of the bearing
(when slid into position, the said slots accommodating the said screws) can be at once
secured. The roller or other said part can be removed upon loosening the said wing
nuts, (without removing them from their bolts) and sliding the removable part of the
bearing away. The other end of the spindle of the roller enters a socket in its
actuating mechanisın.
A special advantage attendant upon this improved method of supporting the fluted
butter working roller is that it permits of the roller being readily removed for any
necossary purpose, and of rollers with differently shaped or sized corrugations being
readily applied and used as required in the same machine.

Improvements in or Applicable to the Construction of Butter
Workers.
I; THOMAS BRADFORD, of High Holborn, in the County of Middlesex, Laundry
and 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 construction
of rotating butter workers in which the butter is worked by a radially disposed
rotating fluted 'conical butter working roller working in a rotating circular cone
bottomed trough supported by a vertical shaft.
The application of the improvements to a butter working machine of the class
above indicated is illustrated on the accompanying drawings in Fig. 1.
Fig. 2 represents an enlarged detail view.
In accordance with the present improvements, I adapt the bottom end of the
shaft, 3, which slides in top and bottom bearings 4, 5, with an adjustable appliance as
hereinafter described by means of which it and the said trough, 6, can be raised or
lowered as required, so that the distance between the working faces of the said
roller, 7, and trough, 6, can be adjusted as and as often as required, so that butter or
other fatty substances such as margarine of greater consistency or hardness can first
be passed between the roller and trough in larger lumps or quantities, and after heing
worked into thinner layers the working space between the said roller and trough
bottom can be decreased. The said means of adjustment consist of a hand wheel, 8,
or its equivalent fast on a screwed rod, 9, which passes through a tapped nut, 10,
bolted to the bottom stay, 11, and upon the top of which screwed rod the shaft, 3,
rests so as to be caused to be raised or lowered when the screwed rod, 9, is turned by
the hand wheel, and of a lock lever, 12, working on the screwed rod and by means of
which the shaft and the trough carried thereby can be instantly locked in any required
position of elevation relatively to the said roller.
The said roller and all other such working parts as the Butter Guards, 13, the Butter
Guides, 14, and the Doffer or Clearer, 15, which removes the Butter from the Roller,
are also, in accordance with the present improvements applied to their respective
bearings or supporting parts in such a manner as hereinafter described as that they
can be readily removed therefrom for cleaning or any necessary purpose and as readily
replaced in position. I attain such object as regards the roller, 7, by constructing its
bearing, 16, with a sliding piece, 17, which is formed with slots, 18, the opposite part
of the bearing being provided with projecting screws, 19, and wing-nuts, 20, by
means of which the removable part, 17, when slid into position, (the said slots accom-
modating the said screws) can be at once secured. The roller can be removed upon
loosening the said wing nuts, (without removing them from their bolts) and sliding
the removable part of the bearing away. The other end of the spindle of the roller
enters a squared socket, 21, in its actuating mechanism.

page_text: The supporting parts, 22. of the butter guards, butter guides and the doffer are
similarly formed with slots, 18*, and are secured and released by wing nuts, 20x,
working on screwed bolts, 19x, projecting from the frame, 23, of the machine.
A special advantage attendant upon the hereinbefore described improved method
of supporting the fluted butter working roller is that it permits of the roller being
readily removed for any necessary purpose, and of rollers with differently shaped
or sized corrugations being readily applied and used as required in the same
machine.
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
clain is ;-
The hereinbefore described improvements in or applicable to the construction of
butter working apparatus of the class hereinbefore referred to, the same con-
sisting in :-
1. Adapting to the vertical shaft carrying the rotating circular cone bottomed
trough or butter working table means of adjusting the same vertically so as to vary
the distance between the trough and the fluted conical butter working roller as
required substantially as hereinbefore described.
2. Supporting the butter working roller, the butter guards, the butter guides and
the doffer or cleaner in slotted removable bearings adapted substantially as hereinbefore
described.
