Complete Specification Left, 3rd Mar., 1898-Accepted, 20th May, 1898
We, WILLIAM WHITAKER, Adamsons Farm, Burnley, in the County of Lancaster,
Brick Manufacturer, and JAMES, HENRY HEAP, 8, Saint James Street, Accrington,
in the County of Lancaster, Brick Manufacturer, do hereby declare the nature
of this invention to be as follows:-
This invention relates to screens for screening ground shale, clay, or other
material for brick making and other purposes. It is designed in the form of a
rectangular frame or other suitable form of any required length or width. The
frame is made of suitable depth and material, secured at each end with a cross
piece, also a cross piece at a suitable distance from each end.
At each end and in connection with the cross pieces we form wrest boards,
fitted with wrest pins similar to what are used in pianos, or other suitable form of
pins for the purpose of stretching wires lengthway of the open part of the frame
in the middle, thereby forming the screening part which is fixed at a suitable
angle, and upon which the material to be screened is thrown or passed.
The wrest pins are so arranged as to stretch the wires over a bridge part, formed
of suitable material and in connection with the wrest boards at the top and bottom
of the screen space, at equal distances apart according to the fineness of the
material required. Each end of the wrest board and pins are covered with a
metal plate so that the material may pass direct on to the wires, the screened
material passing through, and the tailings over and away to be reground.
Our object is to screen a damper material and prevent clogging, and dispense
with any mechanical motions, thereby saving labour and power.

This invention relates to screens for screening ground shale, clay, or other
material for brick making and for other purposes. In the accompanying drawings,
Fig. 1. is an elevation, part in section of end of frame.

page_text: Fig. 2. is a plan of end of frame with part of wrest board.
It is designed in the form of a rectangular frame a, or other suitable form of any
required length or width. The frame is made of suitable depth and material,
secured at each end with a, cross piece b, also a cross piece c, at a suitable distance
from each end. At each end and in connection with the cross pieces we form.
wrest boards d, fitted with wrest pins e, e, similar to what are used in pianos, or
other suitable form of pins, for the purpose of stretching wires f, lengthway of

which is fixed at a suitable angle and upon which the material to be screened is
thrown or passed. The wrest pins are so arranged as to stretch the wires over a
bridge part g, formed of suitable material and in connection with the wrest boards
at the top and bottom of the screen space at equal distances apart according to
the fineness of the material required. Each end of the wrest board and pins is
covered with a metal plate. so that the material may pass direct on to the wires, the
screened material passing through, and the tailings over and away to be reground.
Our object is to screen a damper material and prevent clogging and dispense with
any mechanical motions, thereby saving labour and power.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
wo claim is:-
1. The combination of frame and wrest boards, with wrest pins, as and for the
purpose set forth and described.
2. The combination of frame, wrest boards, and wrest pins with bridges as and
for the purpose set forth and described.
3. The combination of frame, wrest boards, wrest pins and bridges, with wires
stretched over as and for the purpose set forth and described.
