PROVISIONAL SPECIFICATION.
The Manufacture of Fumigating Blocks or Bricks.
I, EDWARD JOSEPH KENNEDY, of the firm of J. & E. Kennedy, of 88 and 89,
Amiens Street, in the city of Dublin, Tobacco Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the manufacture of fumigating blocks or bricks for the
destruction of insects on plants and flowers in greenhouses and other places, the
object of the improvements being to provide a valuable fumigating agent which
would be harmless to vegetation and at the same time economical, powerful in its
effects, and portable.
In manufacturing my fumigating blocks or bricks I employ stringy peat or turf
and mix the same with essence of tobacco, adding thereto tobacco paper and tobacco
rag, cut into small pieces, the whole being then thoroughly mixed together until a
pulp is formed. I then mould this pulp into blocks or bricks of the required shape
or size by any suitable apparatus. The apparatus which I have found to answer
well for this purpose consists of a frame divided into a number of chambers of the
depth, width and length to be given to the blocks or bricks.
The pulp being placed in these chambers, plungers or blocks are then brought
down into each chamber or mould so as to compress the composition and render it
more compact and to force some of the moisture therefrom.
The frame thus charged is then taken to a steam press and stoved and pressed,
and, on the frame being removed, the bricks can, as soon as they become cool, be
knocked out of the frame when they are ready for sale.

COMPLETE SPECIFICATION.
The Manufacture of Fumigating Blocks or Bricks.
I, EDWARD JOSEPH KENNEDY, of the firm of J. and E. Kennedy, of 88 and 89,
Amiens Street, in the city of Dublin, Tobacco 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 :―
This invention relates to the manufacture of fumigating blocks or bricks for the
destruction of insects on plants and flowers in greenhouses and other places, the
object of the improvements being to provide a valuable fumigating agent which
would be harmless to vegetation and at the same time economi cal, powerful in its
effects, and portable.
In manufacturing my fumigating blocks or bricks I employ stringy peat or turf
and mix the same with essence of tobacco, adding thereto tobacco paper and tobacco
rag, cut into small pieces, the whole being then thoroughly mixed together until a
pulp is formed. I then mould this pulp into blocks or bricks of the required shape
or size by any suitable apparatus.
In the accompanying drawing-
Figure 1 is a sectional elevation of an apparatus which I have found to answer well
for this purpose.
Figure 2 is a plan of part of the same.
The annaratus consists of a frame a divided into a number of chambers b. b of the

page_text: provided with lugs c, c and screw-bolts d, d to allow of it being readily fastened
down upon and removed from a table e or the like.
The pulp being placed in the chambers 6, plungers or blocks f₁f figure 1 (operated
by any suitable means, not shown in the drawing) are then brought down into each
chamber or mould so as to compress the composition and render it more compact
and to force some of the moisture therefrom.
The frame a thus charged is then taken to a steam press and stoved and pressed,
and on the frame being removed, the bricks can, as soon as they become cool, be
knocked out of the frame when they are ready for sale.
For the purpose of illustration I have shown the apparatus arranged to produce
rectangular shaped blocks but it will be obvious that it may be constructed to form
blocks of other shapes.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The manufacture of fumigating blocks or bricks from stringy peat or turf
mixed with essence of tobacco, tobacco paper and tobacco rag, substantially in
the manner hereinbefore described.
2. The use in the manufacture of the said fumigating blocks or bricks, of the
apparatus herein before described and illustrated in the accompanying drawing.
