page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings in the County of Middlesex, 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 object of this invention is to provide a new mason's hawk of increased durability,
one that will not absorb water when brought into contact with the plaster and thus
become unduly heavy, and one that, when not in use, will not warp and split when dry.
The invention consists in the arrangements and combination of parts substantially
as will be hereinafter set forth and finally be embodied in the clauses of the claim.
Referring to the accompanying drawing in which like letters indicate corresponding
parts in each of the Figures-Figure 1 is a side elevation of the improved hawk,
Figure 2 is a vertical section of the same, Figure 3 is a plan of the underside of said
hawk and Figure 4 is a vertical section illustrating certain modifications of construction.
In said drawing, a is a handle which provides a base or support for the board for
holding the plaster. Said handle is preferably of wood.
bis said plaster holding board. This is of terra-cotta such as is used commonly for
building purposes, or it may be of other like earthern material. Said board is saturated
with shellac or other resisting matter which completely fills the pores of the board.
Through the centre of the board as shown in Figures 2 and 4, is or may be arranged
a sheet of wire-cloth c, which adds strength and cohesion to the board, preventing the
same from fracturing should it accidentally fall. The wire-cloth may be inserted
between two of the earthen boards while they are in plastic or semi plastic state, the
plates or boards being then subjected to pressure and firmly united and then burned.
In Figures 2 and 3 is shown an improved handle, the same being provided with a
flange m by which the handle is secured to the plaster board by screws from the

page_text: bottom as shown, or it may be secured in the manner indicated in figure 4, that is the
handle may be inserted through the bottom section imbedding the flange therein while
in a plastic state and before the top section and the wire cloth are placed in position
and subjected to the requisite pressure and burned or baked, as above described, as
will be readily understood by reference to said Figure 4, in which case no other 5
fastening for the handle or flange is required, as will be manifest.
Having now particularly described and ascertained the nature of my said invention'
and in what manner the same is to be performed, I declare that what I claim is :—
First. The improved mason's hawk, combining therein a terra-cotta or similar
earthen board and a handle, substantially as and for the purposes set forth.

and handle, substantially as and for the purpose set forth.
4. A mason's hawk having the body or board thereof composed as a whole or in
part of terra-cotta or equivalent plastic material substantially as set forth.
5. A mason's hawk having the body or board of terra-cotta and wire-cloth,.
