Improvements in Saw Sets.
I WILLIAM WILLOTT POPPLEWELL of 17 & 18 Southampton Buildings W.C. in
the county of Middlesex Patent Agent do hereby declare the nature of this invention
(which has been communicated to me from abroad by Francis Titus Luqueer Lane of
280 Broadway in the City County and State of New York United States of America
Engineer) and in what manner the same is to be performed to be as follows :—
The object of this invention is to provide a new and improved saw set which can
readily be adjusted for setting saw teeth of different sizes and for spreading the
teeth more or less as may he desired..
The invention consists in the combination with a head and its handle of another
handle pivoted in said head and provided with a diamond-shaped setting jaw having
its bottom ronnded.
The invention further consists in the combination with said handles, head, and
jaw, of an adjustable gauge and an abutment for the saw blade, and in the con-
struction and combination of other parts and details as hereafter described.
Referring to the accompanying drawings,
:
Figure 1. is a side view of our improved saw set, parts being in section and others
broken out
Figure 2. is a top-view of the same.
Figure 3. is a bottom-view of one end part of the same, parts being broken out and
others being in section.
Figure 4. is a side-view of one end part of the same showing a modified
construction.
Figure 5. is an end view of the same.
Similar letters of reference indicate corresponding parts.
The handle A and head A' are made integral and the latter is provided with the
slat A in which the curved hanille B is pivoted. On the end of the handle B the
setting jaw B is formed which is diamond shaped and has its bottom curved so as to
adapt it to set teeth of different lengths or sizes.
The head A' has a transverse slot C extending from the front and inwardly and
serving to receive the saw blade M.
The tongue C forming the top of the recess C is provided with an opening C
forming a continuation of the slot A and into the said opening the jaw B¹ projects.
The abutment for supporting the saw blade may be fixed or adjustable the latter
construction being shewn in Figures 1. 2 and 3. and the former in Figures 4
and 5.
The adjustable abutment consists of the screw D screwed through the bottom of
the head A and provided with a lock nut D' for keeping it in the desired position.
A U-shaped frame E is mounted to slide on the sides of the head A on which
it is guided by pins E projecting from the sides of the head into longitudinal
slots E in the shanks of said sliding frame.
Gago lugs against which the ends of the teeth can be rested project laterally
from the shanks of said sliding frame E.
A pin G projects from the end of the head A' and is surrounded by a tubular
screw H, the thread of which engages the thread of an aperture in the closed end
of the slide E the said screw having a milled or other head for turning it.
By turning the said screw the slide E is moved lengthwise and the gauge ends F
can be adjusted a greater or less distance from the abutment according to the length
of the tooth.
A stop-screw J is provided in the handle B, and a spring K for pressing the two
handles from each other is provided on the handle A. In case a fixed abutment is

page_text: used as shown in Figures 4 and 5. the bottom of the recess C is provided with the
offset C-Figure 4.
The gauge lugs F are adjusted according to the length of the saw teeth, the saw
blade M is placed in the recess A and upon the abutment the teeth resting against the
gauge lugs F and then the handles A and B are pressed toward each other, whereby
the teeth are spread or set by the jaw B¹.
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
In a saw set the combination with a slotted head and its handle, of a handle pivoted
in said head and having a diamond shaped setting jaw, a sliding gauge on said head,
a pin fixed in the end of the head, a tubular screw surrounding said pin and screwed
through a threaded aperture in the closed end of the sliding gauge and an abutment
on the above mentioned head, substantially as herein described and illustrated in the
accompanying drawing.
