Improved Apparatus for use in the Construction of Dry Walls.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, (a communication to me from abroad by Elmon Adams,
of Washington, District of Columbia, U.S.A., Inventor,) do hereby declare the
nature of this invention to be as follows:-
This invention relates to certain apparatus for use in the construction of dry
walls which have openings; and it consists of a follower, which is provided with
a spring which is attached to its lower end, for holding it in place in said opening
in the wall, and which is also provided with a fibrous or brushy substance for
cleaning the sides of the opening when inserted therein.

COMPLETE SPECIFICATION.
Improved Apparatus for use in the Construction of Dry Walls.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a communi-
cation to me from abroad by Elmon Adams, of Washington, District of Columbia,
U.S.A. Inventor,) to be as follows:-
Figure 1 is a top plan view of a portion of one form of wall in the construction
of which my follower can be advantageously used.
Fig. 2 is a view of my follower to be used in the construction of dry walls.
Fig. 3 is another view of the follower provided with a brush or scraper.
In Fig. 1 is shown one form of dry wall in the construction of which my follower
can be advantageously used. A detailed description of this wall is not given
further than that the bricks C and E are of such shape that when the wall is built
openings or holes, as B, are formed in it.
Referring now to Fig. 2, G represents a follower which is designed to be used
during the process of construction of the wall, and this follower is made of such
shape as to practically fill the opening B through the wall, as shown in Fig. 1.
This follower may be made of wood, cork, or of any light material, or it may be
made of tin or any kind of sheet metal. If made of wood or any light fibrous
material, it may or may not be made hollow. The lower end of the follower is
provided with a spring H, which is secured to the bottom of the follower in any
suitable manner-such, for instance, as using a screw or a staple-to hold it
securely to the follower. The upper end of the follower G is provided with a
suitable handle J, the use of which is to enable the operator to pull the follower
up as the wall is built.
In practice the follower will have to be a trifle smaller than the opening B in
the wall, and in some instances it may be found desirable to secure to the outside
of the follower a brush of some kind, or to provide the follower in some way
with an elastic or yielding surface, and to that end I may provide a strip K,
which may be made of Brussels carpet or any kind of yielding fibrous material,
or I may use a series of brushes, all of which or either one of which would be
useful in this connection.
In the construction of dry walls which are provided with an opening or
ventilating-flue some difficulty has been experienced by the mortar running out

the sides of the opening, as B, through the wall. When it is desired to use these
openings through the walls for the accommodation of electrical conductors, these
obstructions may be found to be a great source of annoyance, and it is to obviate
this disadvantage that I construct and design to use the follower G. By con-
structing the follower of the approximate size and shape of the opening through
the wall and lifting it along up through the opening B in the wall as the wall is
being constructed and before the mortar has become entirely solidified I find that
a clear opening will be left through the wall. In order to secure a more com-
plete finish to the inside walls of this opening, I provide the follower with the
bushes or fibrous material K, as above described. In order to prevent the
follower from accidentally slipping down through the opening in the wall where
it could not be reached, I provide it with a spring, as above described.
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 :
1. A follower for use in the construction of dry walls provided with openings or
air-chambers, said follower having a spring affixed to its lower end for holding it in
place in said opening in the wall.
2. A follower for use in the construction of dry walls having an opening, said
follower being provided with a spring attached to the lower end for holding it in
place in said opening in the wall, and also with a fibrous or brushy substance for
cleaning the sides of the opening, substantially as shown and described.
3. A follower for use in the construction of dry walls which are formed with an
opening, said follower having a spring attached to its lower end and extending
beyond its sides for holding it in place in said opening, and also with a brush or
fibrous scraper, all substantially as shown, and for the purpose set forth.
