Year: 1878

page_text: LETTERS PATENT to Henry Cockey and Francis Christopher Cockey, both of
Frome, Selwood, in the County of Somerset, for the Invention of "IMPROVE-
MENTS IN WOODEN GRIDS FOR GAS PURIFIERS."
Sealed the 15th October 1878, and dated the 17th April 1878.
PROVISIONAL SPECIFICATION left by the said Henry Cockey and Francis
Christopher Cockey at the Office of the Commissioners of Patents on the 17th
April 1878.
"
HENRY COCKEY and FRANCIS CHRISTOPHER COCKEY, both of Frome, Selwood, in
the County of Somerset. IMPROVEMENTS IN WOODEN GRIDS FOR GAS PURIFIERS."
This Invention has for its object the construction of grids in such a manner as to
ensure their durability, and at the same time avoid their liability to become
clogged.
2
Hitherto the bars forming the grids or trays have been made of wood left rough
on their surfaces, and in transverse section, either of a rectangular or of a truncated
conical form. In the one case they soon become clogged, and are very troublesome
to clear, and in the other after a little wear they are so weakened and their inter-
stices so much increased in size as to render them very inefficient.
This Invention consists in planing the whole of the surfaces of the said bars
forming the grids, and in bevilling the sides of the said bars for about two-thirds of
their depth. By thus rendering their surfaces smooth and giving to them such a
sectional form as that just described, great durability is ensured and the possibility
of the grids becoming clogged is considerably reduced, while should they become
choked the ease with which they can be cleared in comparison with those made
with rectangular bars is greatly increased.

This Invention has for its object the construction of grids in such a manner as

clogged.
Hitherto the bars forming the grids or trays have been made of wood left rough
on their surfaces, and in transverse section, either of a rectangular or of a truncated
conical form. In the one case they soon become clogged, and are very troublesome
to clear, and in the other after a little wear they are so weakened and their inter-
stices so much increased in size as to render them very inefficient.

of the grids becoming clogged is considerably reduced, while should they become
choked the ease with which they can be cleared in comparison with those made
with rectangular bars is greatly increased.
In order that the foregoing may be more easily understood, Drawings are attached
hereto, of which the following is a description:-
Fig. 1 is a plan of a part of a grid, and Fig. 2 is a section through A, B,
Fig. 1.
In each of the Drawings similar letters refer to the same parts, C, C, being the
outside frame of the grid, and D, D, the bars thereof, having a section such as is
shown in Fig. 2; E, E, are the distance pieces placed between the bars, and having
corresponding bevels thereto, the whole being secured together by screwed tie rods Ĕ
and nuts G, G.
Having now described and particularly set forth the nature of this Invention, and
the manner in which the same is or may be used or carried into effect, we would
observe in conclusion that we do not confine or restrict ourselves to the preciso
details or arrangements which we have described or referred to, as variations may
be made therefrom without deviating from the principles or main features of this
Invention, but what we consider to be novel and original and therefore claim as the
Invention secured to us by the herein-before in part recited Letters Patent is,―
Firstly. The making of purifier grids with planed or smoothed surfaces.
And, Secondly. In constructing the bars thereof of such a sectional form as is
herein described, and shown on the Drawings.
In witness whereof, we, the said Henry Cockey and Francis Christopher Cockey,
have hereunto set our hands and seals, this Fifteenth day of October, in the
year of our Lord One thousand eight hundred and seventy-eight.
