Improvements relating to the Plastering of Walls.
I, GEORGE W. MESERVE, of 285 Columbus Avenue, Boston, Mass., U.S.A.,
Inventor, do hereby declare the nature of this invention to be as follows:-
This invention relates to the plastering of walls, and it has for its object the
provision of means for enabling a strong and perfectly even acute angle corner
to be made in such manner that it will not be liable to be easily chipped.
The invention consists of a piece of sheet metal of proper length, bent longitudin-
ally to an angle which permits one of its edges to form the extreme apex of the
corner whilst its other side rests flat upon and is nailed to the laths, or is built into
the wall. The metal is perforated in order to allow of its being readily nailed,
and also to permit of the plaster passing through it to ensure the firm adhesion
thereto of the plaster.
The plaster is laid upon the wall flush with the edge of the metal plate on both
sides thereof, as will be readily understood.

I, GEORGE W. MESERVE, of 285 Columbus Avenue, Boston, Mass., U.S.A.,
Inventor, 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 my invention relates to improvements in metal corner plates or beads used by
plasterers in the construction of plastered walls, to form outlines or guides for the
trowel, clinching spaces for the mortar, and protection for the finished work where
corners, arrises, sweeps, angles and arches occur.
Reference being had to the drawings hereunto annexed;
Fig. 1. illustrates that form of my invention usually employed and the manner
of attaching the same to the furring strip.
Fig. 2 is an elevation of a corner of a building shewing the method of
employing my invention as shewn in Fig. 1.
Fig. 3 is a cross section through Fig. 2.
Fig. 4 is a part elevation shewing an alternative method of securing the guide
strip to a wall; Fig. 5 is a cross section therethrough; and Fig. 6. is a detail view
enlarged.

page_text: Fig. 7., illustrates my invention as applied to the formation of rounded corners,
and Fig. 8 is a cross section therethrough.
Fig. 9., illustrates the method of using my invention in the inner corners of
rooms and the like places.
Fig. 10., illustrates a form of my invention for securing caps, corbles, ornaments
and the like in the face of stone and terra cotta walls, and Fig. 11., shews the
manner of employing the same.
Fig. 12 illustrates an alternative form of the invention used for the purposes
referred to with respect to Figs. 10 & 11, and is especially applicable to the
securing of new buildings to old walls.
In carrying out my invention, I utilize the blanks from which stampings, such
as the links of cycle chains, caster wheels and the like, are made and which, in the
ordinary course are treated as waste. It will therefore be readily understood that
I utilize material which, although cheap, is especially applicable to my purpose,
inasmuch as the perforations create a firm hold on the mortar when it is pressed
therein or the tie-pieces are firmly embedded.
I now proceed to more fully describe my invention, reference being had to the
drawings and to the figures and letters of reference thereon; like letters referring
to similar parts throughout all the views.
The metal guide strip A, having perforations B is bent longitudinally to a
suitable angle, as shewn in Fig. 1., and may be secured to the furring strip C by
staples or the like D. The furring strip C is secured to the lathing in the usual
manner, so that the metal strip A projects from the corner, best seen in Fig. 3,
and the plaster E, is worked up to its edge as shewn.
In Figs. 4, 5 & 6 I shew an angle plate F having apertures G through which
nails H may be driven to secure it to the corner of a wall. A T-shaped portion I
is stamped out of one side of the angle plate and bent upwards at right angles to
form a button. The strips, A are secured to the button by being held in such a
position that their perforations will pass over it, as indicated in dotted lines in
Fig. 6., and are thereby retained when the strip is vertical as shewn in Fig. 4.
In Figs. 7 and 8 the metal strip A is shewn as secured to the furring strip but
it is curved as shewn so that a rounded corner can be readily formed over it; the
plaster penetrating the perforations being thereby bound together and prevented
from cracking.
It is well known that corners of rooms are apt to crack more especially where
a firm wall on one side unites with a flexible partition on the other side. Now by
this my invention, the difficulty is readily overcome. The plate or strip A (Fig. 9)
is bent laterally to conform to the angle, and one wing is nailed through the
securing strip to the studding whilst the other is left free against the brickwork,
from which the plaster is drawn bodily by any shrinkage of the lathing, without
breaking through into the room or shewing on the surface.
In Fig. 10 is shewn the form of strip used for securing caps, corbles, ornaments
and the like in the face of stone, terra cotta or the like walls, and it consists of a
suitable length of perforated metal strip having an upturned portion J. In Fig. 11
the strip is shewn at K with its end J embedded in a cavity of the facing stone M
at L; its other portion extending across to and being embedded in the mortar
between the bricks of the wall N. In some cases the upturned part J may be
dispensed with and the plain perforated strip simply laid across from wall to facing
stone, as shewn at O.
Another form of the invention, and a modification of that last described, and
more especially applicable for retaining a new wall firmly to an existing wall with-
out removing some of the bricks of the old wall to interlock the new ones therewith
as is now customary, consists of a strip of perforated metal bent about midway its
length to a right-angle. This form is shewn in Fig. 12 where P represents the
old wall, the new one or facing stones, and R the tie, which is shewn at S as
nailed to the wall P whilst its other arm is embedded in the mortar between the
bricks of the wall Q.

page_text: It will be understood that various modifications may be made in the form of
the strips and ties to suit different positions and eventualities without departing
from the nature of my invention.
I am aware that metal strips have heretofore been' employed as ties in the con-
struction of walls but the metal employed, besides being of inferior quality, con-
sequently more liable to perish, and costing as much or more than the best metal
-usually steel used by me in carrying out my invention,-have no substantial
hold on the mortar, which object is most efficiently attained, in my invention, by
reason of the perforations, and, moreover, the employment of which perforated
metal strips for building purposes is, to the best of my knowledge and belief
absolutely novel.
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/ The herein described improvements relating to the plastering of walls, said
improvements consisting in the employment of a perforated metal strip firmly
secured to the furring strip, hent longitudinally to an angle, and the plaster worked
up to its edge, all substantially as and for the purposes herein before set forth and
illustrated in the drawings hereunto annexed.
2/ The alternative method of and means for securing the metal guide strips
to the wall, said means consisting of an angle plate nailed to the wall, a T-shaped
piece stamped from the angle plate and bent at right angles to form a button, and
said method consisting in placing the strip so that the button interlocks with an
aperturture in the strip, all substantially as and for the purposes hereinbefore set
forth and illustrated in the drawings hereunto annexed.
3/ In a building, the herein described method of and means for forming corners,
said means consisting of a metal perforated strip, secured to the furring strip,
extending outwardly therefrom, curved or bent in such manner as to form rounded
or any desired shaped corner, and the plaster formed around the strip, all substan-
tially as and for the purposes herein before described, more especially with reference
to Figs. 7 and 8 of the drawings hereunto annexed.
4/ The herein described method of and means for preventing cracks in the
plastering of walls, said method and means consisting in securing one arm of a
perforated angle strip to the furring strip and lathing of one wall or partition
whilst its other arm or leaf rests against the meeting wall behind the plaster, sub-
stantially as and for the purposes herein before set forth and illustrated with
reference to Fig. 9 of the drawings hereunto annexed.
5/ The herein described method of and means for securing facing blocks, caps,
corbles, ornaments and the like in the face of stone and terra cotta walls, said
