Engineer JOHN WILLIAM JAGGARD 27 St. Andrew's Street North Bury St. Edmunds
Engineer's Draughtsman, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the method of regulating the trays used in the interior of
revolving cellular cylinders, for the purpose of catching the cockles or seeds discharged
by the cells or indents which form the inner surface of such cylinders.
The said tray is usually attached to a spindle which runs from end to end of the
cylinder, and through the boss of a wheel forming the cylinder end, and outside this
wheel resting on a bracket which is seated on the frame in which the cylinder is
suspended.
This bracket is usually furnished with a set screw, and the spindle provided with a
handle, and sometimes with a quadrant with bolt and wing nut and when altering the
tray, this holt or set screw, or both are loosened, when the tray can be controlled by
the handle or lever, the set screw being tightened again after tray has been adjusted
up or down.
!
In place of this arrangement which has been found inconvenient, we substitute a
bracket or pedestal, through which the bar or spindle to which the tray is attached
passes, and on the outer side of this we thread a quadrant having teeth on the upper
edge.
On the bracket or pedestal is provided two bearings, a worm spindle and hand
wheel, the said worm gearing into the teeth on the upper edge of the quadrant. This
worm and quadrant provided with the hand wheel, form a contrivance enabling us
to adjust the tray in the above method to the smallest and most exact movement.
The said pedestal and quadrant are provided with a dial and arrow shewing the exact
movement of the tray.

CHARLES EDWARD MUMFORD Saint Andrew's Iron Works Bury St. Edmunds
Engineer JOHN WILLIAM JAGGARD 27 St. Andrew's Street North Bury St. Edmunds
Engineer's Draughtsman 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 the method of regulating the trays used in the interior of

page_text: revolving cellular cylinders, for the purpose of catching the cockles, seeds, stones and
the like which are lifted by the cells or indents which form the inner surface of such
cylinders, which are of well known construction.
The said tray is usually attached to a spindle which runs from end to end of the
cylinder, and through the boss of a wheel at each end of the said cylinder, forming
the cylinder ends, and, outside this wheel resting in a bracket, which is seated on the
frame in which the cylinder is suspended. But sometimes the said tray is of sufficient
strength to be supported only by a gudgeon at each end instead of the spindle running
through the entire length.
This bracket is usually furnished with a set screw, and the spindle provided with a
handle, and sometimes with a quadrant with bolt and wing nut, and when altering the
tray, the bolt or set screw or both are loosened, after which the tray which is attached
to the spindle can be shifted up or down by means of the handle or lever which is
attached to the spindle or gudgeon end of tray, the set screw being tightened again
after the tray has been adjusted up or down as required.
In place of this arrangement which has been found inconvenient, we substitute a
bracket or pedestal, described hereafter, through which the bar or spindle passes loose,
and on the outer side of this we fix on the said spindle or gudgeon a quadrant having
teeth on its upper edge. On the bracket or pedestal is provided two bearings forming
part of the said pedestal, and arranged thereto a worm, spindle and hand wheel, the
said worm gearing into the teeth on the upper edge of the quadrant. This worm and
quadrant provided with the hand wheel form a contrivance enabling the operator to
raise or lower the tray to the smallest and exact movement.
The said pedestal and quadrant are provided with a dial and arrow showing the
exact movement registered by the tray, when and where set.
We now proceed to describe the regulating bracket and pedestal with reference to
the accompanying drawing in which
Figure 1 is a representation of the front view of such a cylinder of well known
construction shewing the new regulating bracket attached.
Figure 2 is a front view of the new regulating bracket.
Figure 3 is a side view of same.
A is the bracket or pedestal provided with a dial.
B B are the two bearings which form part of the said bracket A, through which
the spindle D passes.
C is the worm to which is attached the spindle D, to which is also attached the
hand wheel E.
G is a quadrant which is fixed on to the spindle or gudgeon H and immediately in
front of the bracket A, and is provided with a pointer.
The quadrant G having teeth on its upper edge is geared into the worm C fixed to
the spindle D provided with hand wheel, hence when the hand wheel E is turned, the
tray attached to the spindle H can be moved up or down with the greatest exactness,
either during the time that the cylinder itself is in motion or at rest.
Having now particularly described and ascertained the nature of our said inven
tion, and in what manner the same is to be performed, we declare that what we
claim is,
The invention of a regulating bracket for raising, lowering, or setting the tray
used in the interior of cellular cylinders used for sorting cereals, powders or othe
substances.
