GEORGE FREDERICK REDFERN, of the General Patent Office, 4, South Street;
Finsbury, in the County of Middlesex, Patent Agent. AN IMPROVED GLAZIER'S
TOOL." [A communication from abroad by William Henry Giles Savage and Henry
Augustus Betts, both of Kingston, in the Province of Ontario, and Dominion of
Canada.]
The object of this Invention is to furnish glaziers and manufacturers of picture.
frames and others with a tool for holding and driving the sheet metal points or
brads into the frame for holding the glass or wooden back in place.
It consists of a prismatic receptacle with a follower actuated by a spring, the said
receptacle being joined at right angles to a bar with a triangular opening in line
with the receptacle, and on the opposite side of the bar from the receptacle is made
a longitudinal rabbet covered by a metallic plate, and into the socket thus formed a
plunger is reciprocated, which drives the brads or points into the wood when they
have been forced out into the socket.
In carrying out the Invention a plunger is provided with a handle at one end, and
having a longitudinal slot through which is passed a set screw, which enters a bar
or plate. A longitudinal rabbet is made in the bar, extending its entire length, and
the plunger moves freely in this rabbet, it being limited however in its movement
by a screw, which likewise holds it in place.
At the lower end of the bar is screwed a metallic plate covering the rabbet, so
that the plunger moves inside of it when reciprocated.
The bar is likewise provided with a triangular opening under the said metallic
plate, from which opening on the opposite side of the bar from the plate extends at

page_text: right angles a prismatic receptacle or triangular trough, the angles and sides of
which coincide with the angles and sides of the opening in the bar, from which it
extends. This trough is provided with a hinged or sliding door, as may be pre-
ferred, which completely covers it in.
Inside the trough is placed a spiral spring, one end bearing against the end of the
trough, while the opposite end is provided with a follower which bears against the
last one of the number of triangular metallic points placed in the receptacle; these
points are placed in the trough, commencing at the end where it joins the bar, and
the spring is retracted to make way for them. The action of the spring keeps these
points pressed up to the end of the receptacle, and the last one on the end opposite
the spring bears against the inside of the plate when the plunger is withdrawn, the
space being sufficient to admit one only.
The operation of the device is as follows:-The receptacle being filled with the
points and the trough closed in, the plunger is withdrawn as far as it will go. The
tool is then turned with the receptacle in an upright position, while the plate bears
upon the wooden back or pane, as the case may be, while the end of the bar is
placed against the side of the frame at the point where the metallic point is to be
driven in. The plunger is then driven in, and its end coming in contact with the
base of the point drives it forward and into the side of the frame. As soon as the
plunger is drawn back the spring forces the points forward, and another takes
the place of the one driven out by the plunger.
In this way great facility and rapidity in driving these points are obtained, and
the trouble and time occupied in picking up the points and entering them into the
wood ready for the action of the hammer is avoided.
In a modification of the Invention, at the opposite end of the trough from the bar
a socket is provided, into which the spring is entered. By forcing the spring back
into this socket it will be found easier to place the points in the receptacle or cloth.
This is likewise provided with a hinged lid instead of a sliding one, but one or the
other can be used indifferently.
A hole is made in one side of the trough close up to the socket. When the spring
is pushed back preparatory to filling the trough with the brads, a piece of wire is
put through the hole, so it will project across the end of the spring or follower and
hold the spring back in the socket, thus enabling the workmen to employ both
hands in filling the receptacle.

GEORGE FREDERICK REDFERN, of the General Patent Office, 4, South Street,
Finsbury, in the County of Middlesex, Patent Agent. "AN IMPROVED GLAZIER'S
TOOL." A communication from abroad by William Henry Giles Savage and Henry
Augustus Betts, both of Kingston, in the Province of Ontario, and Dominion of
Canada:
The object of this Invention is to furnish glaziers and manufacturers of picture
frames and others with a tool for holding and driving the sheet metal points or
brads into the frame for holding the glass or wooden back in place.
It consists of a prismatic receptacle with a follower actuated by a spring, said
receptacle being joined at right angles to a bar with a triangular opening in linė
with the receptacle, and on the opposite side of the bar from the receptacle is made
a longitudinal rabbet covered by a metallic plate, and into the socket thus formed a
plunger is reciprocated, which drives the brads or points into the wood when they
have been forced out into the socket.
But to make the Invention communicated to me better understood I will proceed
to describe the same by reference to the accompanying Drawing, in which Figure 1
is a plan of the improved tool; Figure 2 is a side elevation of the same; Figure 3 is
à sectional detail of the receptacle; and Figure 4 is a modification of the improve-
ments. Similar letters of reference indicate corresponding parts.
Referring to the Drawings, A represents a plunger provided with a handle at one
end; and having a longitudinal slot b, through which is passed a set screw d that
enters the bar or plate B. A longitudinal rabbet a is made in the bar B, extending
its entire length, and the plunger moves freely in this rabbet, it being limited how-
ever in its movement by the screw d, which likewise holds it in place.
At the lower end of the bar is screwed a metallic plate f covering the rabbet, so
that the plunger moves inside of it when reciprocated. The bar B is likewise pro-
vided with a triangular opening under the plate f, as shewn by the dotted lines in
Figure 2. From this opening on the opposite side of the bar from the plate f
extends at right angles the prismatic receptacle or triangular trough C, the angles
and sides of which coincide with the angles and sides of the opening in the bar B,
from which it extends. This trough is provided with a hinged or sliding door, as
may be preferred, which completely covers it in.
Inside the trough is placed a spiral spring e, one end bearing against the end f¹
of the trough, while the opposite end is provided with a follower which bears against
the last one of the triangular metallic points g placed in the receptacle..
These points are placed in the trough, commencing at the end where it joins the
bar B, and the spring is retracted to make way for them. The action of the spring
keeps these points pressed up to the end of the receptacle, and the last one on the
end opposite the spring bears against the inside of the plate when the plunger is
withdrawn, the space being sufficient to admit one only.
The operation of the device is as follows:-
The receptacle being fitted with the points and the trough closed in, the plunger
is withdrawn as far as it will go. The tool is then turned with the receptacle in an
upright position, while the plate'f bears upon the wooden back or pane, as the case
may be, while the end of the bar B is placed against the side of the frame at the
point where the metallic point is to be driven in. The plunger is then driven in,
and its end coming in contact with the base of the point (which is toward it, as
indicated by the dotted lines in Figure 2), drives it forward and into the side of the
frame. As soon as the plunger is drawn back the spring forces the points forward,
and another takes the place of the one driven out by the plunger.

page_text: In this way great facility and rapidity in driving these points are obtained, and
the trouble and time occupied in picking up the points and entering them into the
wood ready for the action of the hammer is avoided.
In Figure 4 a modification of the Invention is shewn. Here, at the opposite end
of the trough C from the bar B, a socket h is provided, into which the spring is
entered. By forcing the spring back into this socket it will be found easier to place
the points in the receptacle or cloth. This is likewise provided with a hinged lid
instead of a sliding one, but one or the other can be used indifferently.
A hole i is made in one side of the trough C close up to the socket h. When the
spring is pushed back preparatory to filling the trough with the brads, a piece of
wire is put through the hole, so it will project across the end of the spring or follower
and hold the spring back in the socket, thus enabling the workmen to employ both
hands in filling the receptacle.
Having thus described the said Invention communicated to me, and the best
means I am acquainted with for carrying the same into effect, I wish it to be under-
stood that what is claimed and intended to be protected by the before herein in part
recited Letters Patent is,-
Firstly. An improved glazier's tool for driving brads to hold window panes and
wooden backs for pictures in the frame, and other similar purposes, consisting of
the reciprocating plunger A provided with the slot b secured to the plate or bar B,
provided with plate f, in combination with the receptacle C, having a spring e for
forcing the brads or points out of the receptacle, whereby the points, being forced
out of the receptacle against the inside of the plate f, are driven thence by the
plunger A, and entered into the wood, substantially as described.
Secondly. An improved glazier's tool for driving brads or points composed of the
following parts in combination :-The bar B with rabbet for the plunger A covered
at the lower end by the plate f, the plunger A guided and limited by the
screw d, and the receptacle Ĉ provided with spring e, as and for the purpose sub-
stantially as described.
In witness whereof, I, the said George Frederick Redfern, have hereunto set
my hand and seal, this Tenth day of September, in the year of our Lord
One thousand eight hundred and seventy nine.
