I, EDWARD LOWE of Old Hill, in the parish of Rowley Regis in the County of
Stafford, Timber Merchant, and Gas Grid Manufacturer, do hereby declare the nature
of this invention to be as follows:-
The grids for gas purifiers, as hitherto constructed, have, by the action of the
passing gas, become rapidly deteriorated, and after two or three years use, have had
to be renewed. This is due to rapid corrosion of the metal of which the grid is
wholly or in part composed.
Now the object of the present invention is so to manufacture grids, that they will
have no liability to deteriorate through the action of the gas passing through the
purifier, and will be both simple and economical in construction.
To this end, I construct the grids of a number of wooden bars, arranged parallel
to each other, and maintained at equal distances apart by means of distance pieces.
These bars and distance pieces I connect together, by passing transversely through
them, tie rods composed of ash or other hard wood. Screw threads are cut in the
opposite ends of these rods, the threads at one end of the rods being designed to
enter threaded holes in a side bar of the grid, and the threads at the other end, to
receive wooden nuts, which, when screwed home, will hear against the other side
bar, and bold all the parts of the grid firmly together.
These grids, which are intended to carry the purifying material, will take their
place in the gas purifier, like grids of the ordinary construction.
The grid bars I make of a rectangular cross section, or 1 taper them from the face
downwards, to facilitate the flow of the gas upwards, through the purifying material.
Dated this 1st day of March 1888.

page_text: An Improved Manufacture of Grid for Gas Purifiers.
I EDWARD LOWE of Old Hill in the parish of Rowley Regis, in the County of
Stafford, Timber Merchant and Gas Grid Manufacturer, 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 :-
The grids for gas purifiers, as hitherto constructed, have, by the action of the
passing gas, become rapidly deteriorated, and after two or three years' use, have had
to be renewed. This is due to the corrosion of the metal of which the grid is wholly
or in part composed.
Now the object of the present invention is so to manufacture grids, that they will
have no liability to deteriorate through the action of the gas passing through the
purifier, and will be both simple and economical in construction.
To this end, I construct the grids of a number of wooden bars arranged parallel
to each other, and maintained at equal distances apart by means of distance pieces.
These bars and distance pieces I connect firmly together by means of transverse
wooden tie rods in the manner to be presently explained, and I thus avoid the use
of metal in my improved manufacture of grid."
In the accompanying drawing,
Fig. 1 shews in plan view,
Fig. 2 in side view, and
Fig. 3 in transverse section, one form of wooden grid constructed according to my
invention.
A A¹ are the end bars of the grid, made preferably of hard wood, and B B the
intermediate bars, with distance pieces CC interposed between them.
DD are tie rods, which are also made of hard wood.
These tie rods are threaded at their opposite extremities, and enter threaded holes
cut in the bar A. The other ends of the rods are intended to receive round wooden
nuts d, which fit holes bored in the end bar A¹.
Holes are bored through the bars B and distance pieces C, for the passage through
them of the tie rods, and for the purpose of facilitating the tightening up of the rods,
their nuts are formed with squared heads for the reception of a spanner, the turning
of which will cause the tie rods to draw together the bars of the grid, and combine
them into a firm structure.
When thus in place, the heads of the nuts d may be cut flush with the end bar A¹,
as indicated at Figs. 1 and 3, the dotted lines in those Figures indicating the portions
removed.
The bars B in this grid, it will be seen, are rectangular in cross section, but in
some cases I propose to modify the form of grid, as shewn at Figs. 4, 5, and 6, where
the bars B are tapered in cross section from the face downwards, to facilitate the
flow of the gas upwards through the purifying material which is placed upon the
grid, as upon the ordinary grids of the gas purifier.

page_text: In this example, the distance pieces C are made wedge shaped to correspond with
the taper section of the bars B, and the nearer approach of the bars to each other at
their face, is permissible without unduly retarding the upward passage of the gas
through the dry lime or other purifying material used.
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
claim is :-
