ANTHONY WAYNE DOWNS, OF DALLAS, TEXAS, ASSIGNOR OF TWO-FIFTHS TO H. J.
NELSON, OF DALLAS COUNTY, TEXAS.
MASON'S JOINTER.Specification of Letters Patent.
Patented Aug. 1,1916.
Application filed September 22, 1914. Serial No. 863,038.
To all whom it may concern:
Be it known that I, ANTHONY WAYNE
DowNs, a citizen of the United States, re-
siding at Dallas, in the county of Dallas
5 and State of Texas, have invented a new
and useful Mason's Jointer, of which the
following is a specification.
This invention relates to jointers particu-
larly designed for use by stone masons and
10 brick masons, one of the objects of the in-
vention being to provide a simple, durable
and efficient tool of this character which
can be used to cut out mortar to a prede-
termined depth between courses of bricks
15 or the like and to then smooth the surface
of the mortar so that a neat and attractive
joint will be produced.
With the foregoing and other objects in
view which will appear as the description
20 proceeds, the invention resides in the com-
bination and arrangement of parts and in
the details of construction hereinafter de-
scribed and claimed, it being understood
that changes in the precise embodiment of
25 the invention herein disclosed can be made
within the scope of what is claimed, without
departing from the spirit of the invention.
In the accompanying drawings the pre-
ferred form of the invention has been
30 shown.
In said drawings: Figure 1 is an eleva-
tion of the tool in position- upon a wall.
Fig. 2 is a plan view thereof, the wall be-
ing shown in section and the said tool be-
35 ing shown in the position assumed thereby
while removing mortar from between two
courses. Fig. 3 is a view similar to Fig. 2
but showing the tool positioned to smooth
mortar.
40 Referring to the figures by characters of
reference 1 designates a flat shank provided,
at one end, with an inclined portion 2 from
which extends straight parallel runners 3,
the free ends of which are outturned as
45 shown at 4, thus to provide bearing sur-
faces. A tongue 5 is extended from the off-
set portion 2 and between the runners and
this tongue constitutes a backing for a blade
6 in the form of an elongated strip having
50 a longitudinal slot 7 designed to receive
clamping screws 8 which extend into the
tongue 5 and the offset portion 2 of the tool.
The blade 6 is of a width substantially equal
to the distance between two adjoining bricksor blocks. That end of the shank 1 remote 55
from the offset portion 2 is offset as shown
at 9 and has a terminal portion 10. An
arm 11 is extended laterally between the
offset portion 9 and is provided with a
tongue 12 parallel with said offset portion 60
9 and is detachably engaged by a blade 13.
This blade is formed of a strip of material
having a longitudinal slot 14 designed to re-
ceive clamping screws 15 carried by the
tongue 12. 65
The blade 6 is adapted to be used between
courses or between the bricks or blocks
forming a course while the blade 13 is
adapted to be used under the lowermost
course of a wall or the like. In using the 70
device the runners 3 are placed against the
wall A in the position shown in Fig. 2 and
with the end of the blade 6 extending into
the space between the courses. The tool is
then pushed in the direction indicated by 75
the arrow in Fig. 2, so that the mortar in
the path of the blade will be cut out and re-
moved from between the courses. The ex-
posed face of the mortar can be smoothed
by tilting the tool and shifting it in the 80
opposite direction as in Fig 3. The blade
13 is used in the same manner as the blade 6.
The offset portion 9 and its terminal 10,
however, travel along the faces of the bricks
or stones forming the course above the layer 85
of mortar to be acted on by the blade 13.
Attention is called to the fact that the
blade 6 extends slightly beyond the ends of
the runner whereby this blade is especially
adapted for removing mortar in angle bed 90
joints. Importance is also attached to the
fact that by utilizing the offset arm 11 to
which blade 13 is attached, mortar can be
removed from all longitudinal joints irre-
spective of their location in the wall. 95
What is claimed is:-
1. The combination with a shank, of a
runner extending from one end portion
thereof and having a rounded terminal, a
combined clearing out and smoothing blade 100
curved from end to end and having its
concavity facing the runner and its free end
portion extending beyond the terminal of
the runner, and means for adjustably con-
necting the blade to the shank, said blade 105
intersecting the plane of the runner.
2. The combination with a shank, of a
runner extending from one end portion1,193,478.
