I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention to be as follows:-
My invention relates to an improvement in mason's jointers, which are used by
masons for pointing masonry the object being to produce a convenient and effective
device for the purpose.
With these ends in view, my invention consists in a device having certain details
of construction as will be hereinafter described.
If
In carrying out my invention, the frame or body of the device is shaped to form a
double curve, and formed with a deep transverse mortar receiving cavity which has
the form of a slot extending transversely through the box or frame, in which a
pointing lever is located, and hung upon a transverse pin. The outer or pointing end
of this lever is constructed in its inner edge with a concave longitudinally arranged
pointing groove while its inner or operating end is exposed for engagement and
manipulation by the hand of the user. The outer end of the frame of the device is
also constructed in its inner edge with a concave groove virtually forming a
continuation of the groove formed in the edge of the lever. A spring interposed
between the operating end of the lever and the wall at the inner end of the cavity, is
arranged to exert a constant effort to throw the pointing end of the lever inward in
the cavity. The inner or operating end of the lever is made sufficiently elastic to
adapt it to be sprung laterally under a hook formed in the inner end of the frame, so
as to adapt the tool to be conveniently carried and handled when not in use.
desired the inner end of the lever may also be furnished with a finger-loop. In using
the device, the inner end of the lever is disengaged from the hook, leaving the spring
free to operate to throw the pointing end of the lever inward in the slot. Then the
device, which is held in the hand edgewise, is pressed into a mass of mortar, or
cement, with sufficient force to cause the same to enter and fill the cacity. The tool
is then applied to the masonry, and drawn along the joint while sufficient pressure is
exerted upon the inner end of the lever to gradually force the cement out of the tool
into the joints of the masonry. As the cement is forced out while the tool is being
drawn along, it is shaped and formed into convex contour by the moulding or pointing
groove formed in the outer end of the tool. This goes on until all of the cement
taken up by the tool when the same was forced into the mortar, has been pushed out
and applied, the very last of it being formed by the molding groove formed in the
pointing end of the lever, as well as by the groove formed in the body of the tool
itself. The user again forces the tool edgewise into the mortar and applies it to the
joints of the masonry, drawing it along thereon as before described, and so on. It
will readily be understood that by means of my improved tool, masonry may be pointed
with much more rapidity, and neatness than under the old process, which consisted

page_text: in applying the mortar to the masonry, and then molding or shaping it with a grooved
pointing tool, and then wiping the masonry so as to remove the excess of mortar.
It is apparent that in carrying out my invention some slight changes from the
construction herein described may be made. I would therefore have it understood
that I do not limit myself to the exact construction described, but hold myself at
liberty to make such changes and alterations as fairly fall within the spirit and scope
of my invention.
Dated this 29th day of September 1896.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 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 :-
My invention relates to an improvement in mason's jointers, which are used by
masons for pointing masonry, the object being to produce a convenient and effective
device for the purpose.
With these ends in view, my invention consists in a device having certain
details of construction as will be hereinafter described and pointed out in the
claims.
In the accompanying drawing
Figure 1 represents a view in side elevation of a mason's jointer constructed in
accordance with my invention.
Figure 2, a view partly in side elevation and partly in section and showing the tool
charges or loaded with cement preparatory to being used.
Figure 3, a plan view of the device.
Figure 4, a view of the device in transverse section on the line a-b of Figure 1.
In carrying out my invention, as herein shown, the frame or body A of the device
is shaped to form a double curve, and formed with a deep transverse mortar receiving
cavity A', which, as shown, has the form of a slot extending transversely through the
body or frame, in which a pointing lever B is located, and hung upon a transverse
pin B¹. The outer or pointing end of this lever is constructed in its inner edge with
a concave, longitudinally arranged pointing groove B³, while its inner or operating
end is exposed for engagement and manipulation by the hand of the user. The outer
end of the frame A of the device is also constructed, in its inner edge, with a concave
groove A³, virtually forming a continuation of the groove B' formed in the edge of
the lever. A spring C interposed between the operating end of the lever and the wall
at the inner end of the cavity A', is arranged to exert a constant effort to throw the
pointing end of the lever inward in the cavity A¹. The inner or operating end of the
lever is made sufficiently elastic to adapt it to be sprung laterally under the hook A*
formed in the inner end of the frame, so as to adapt the tool to be conveniently
carried and handled when not in use. If desired, the inner end of the lever may
also be furnished with a finger-loop A³, indicated by broken lines in Fig. 1. In
using the device, the inner end of the lever is disengaged from the hook A, leaving
the spring C free to operate to throw the pointing end of the lever inward in the
slot A', as shown in Fig. 2. Then the device, which is held in the hand edgewise, is
pressed into a mass of mortar or cement, with sufficient force to cause the same to
enter and fill the cavity A¹, as shown by the stipple work in Fig. 2. The tool is then

page_text: applied to the masonry and drawn along the joint while sufficient pressure is exerted
upon the inner end of the lever to gradually force the cement out of the tool into the
joints of the masonry. As the cement is forced out while the tool is being drawn
along, it is shaped and formed into convex contour by the molding or pointing
groove A³ formed in the outer end of the tool. This goes on until all of the cement
taken up by the tool when the saine was forced into the mortar, has been pushed out
and applied, the very last of it being formed by the molding groove B2 formed in the
pointing end of the lever, as well as by the groove A2 formed in the body of the tool
itself. The user again forces the tool edgewise into the mortar, and applies it to the
joints of the masonry, drawing it along thereon as before described, and so on.
will readily be understood that by means of my improved tool, masonry may be
pointed with much more rapidity and neatness than under the old process, which
consisted in applying the mortar to the masonry, and then molding or shaping it
with a grooved pointing tool, and then wiping the masonry so as to remove the
excess of mortar.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
1. In a mason's jointer, the combination with a frame or body containing a mortar-
receiving cavity, of a pivotally mounted lever having a pointing end located in the
cavity, and an operating end adapted to be engaged by the hand for manipulation of
the lever, substantially as described.
2. In a mason's jointer, the combination with the frame or body thereof containing
a mortar-receiving cavity, of a pointing lever, one end of which is located in the said
cavity, and a spring for operating the lever in one direction, substantially as
described.
3. In a mason's jointer, the combination with the body or frame thereof containing
a mortar-receiving cavity, and having the inner edge of its outer end constructed
with a longitudinal molding groove, of a pointing lever located in part in the said
cavity, and adapted to force the mortar therefrom, and to be engaged and operated by
the hand of the user, substantially as described.
4. In a mason's jointer, the combination with a doubly curved body or fraine
containing a mortar-receiving cavity, of a lever pivoted in the said frame or body and
having one end adapted to force the mortar from the said cavity, and its other end
adapted to be engaged for manipulation by the hand of the user substantially as
described.
