MARCUS ARETAR KOSSUTII SHOTWELL, OF EL PASO, TEXAS.
MITER-BOX.
SPECIFICATION forming part of Letters Patent No. 649,368, dated May 8, 1900.
Application filed September 14, 1899, Serial No, 730,442, (No model.)To all whon& it ima/ concern,:
Be it known that I, MARCUS ARETAR LOS-
SUTH SHOTWELL, of El Paso, in the county
of El Paso and State of Texas, have invented
5 a new and Improved Miter-Box, of which the
following is a full, clear, and exact descrip-
tion.
This invention relates to improvements in
miter-boxes and the object is to provide a
So miter-box of simple and conparatively-inex-
pensive construction that may be quickly
adjusted to guide a saw at any desired angle.
I will describe a miter-box embodying my
invention and then point out the novel fea-
15 tures in the appended claims.
Reference is to be had to the accompanying
drawings, forming a part of this specification,
in which similar characters of reference in-
dicate corresponding parts in all the figures.
20 Figure 1 is a partial elevation and section,
on the line 1 1 of Fig. 2, of a miter-box em-
bodying my invention. Fig. 2 is a plan view.
Fig. 3 is a section on the line 3 3 of Fig. 1.
Fig. 4 is a plan view of a turn-table employed,
25 and Fig. 5 is a side view of the saw-back re-
ceiver.
Referring to the drawings, 1 designates a
base, of wood or other suitable material, and
upon which is placed a metal plate 2, which
30 may be secured to a bench or other support
by means of screw-rods 3. Removably con-
nected to one side of the base and serving as
a support for the wood to be operated upon
is a shelf 4. This shelf 4 has plates 5, which
35 extend into openings 6, formed in the top of
the base and underneath the plate 2. When
the plates 5 are thus inserted,fastening-screws
7 are to be inserted in the plate 2 and the
plates 5 to hold the same in place. Extend-
40 ed upward between the top of the base and
the shelf 4 is the back plate, consisting of the
two sections 8 9, spaced apart at their inner
or adjacent ends to allow for the angular ad-
justment of a saw, as will be hereinafter de-
45 scribed. Mounted to rotate in the base and
below the plate 2 is a turn-table, here shown as
a disk 10, having a socket-portion 11, which
extends down and rotates in an opening
formed in the base. The under side of the
50 turn-table is provided with a channel in which
bearing-balls 12 are located, the said bear-
ing-balls also engaging in a channel formedin a plate 13, arranged in the base and sur-
round ing the socket 11. Bearing-balls 14 en-
gage in a channel in the upper side of the 55
thin-table and also in a channel formed on
the under side of the plate 2, as clearly illus-
trated in Fig. 1.
Removably placed in the socket 11 is a
guide-cylinder 15, in which the saw guide-cyl- 6o
inder 16 is vertically movable. To prevent
the cylinder 15 from rotating relatively to the
socket 11, the said cylinder is provided on its
outer side with ribs 17 for engaging in corre-
spondinglyr-shaped recesses formed in the in- 65
ner side of the socket 11, and to prevent the
cylinder 16 from rotating relatively to the
cylinder 15 the said cylinder 16 is provided
with ribs 18 for engaging the correspondingly-
shaped channels formed in the inner side of 70
the cylinder 15. Each of the cylinders is
made in two longitudinal sections, with a space
between the sections for the passage of a saw-
blade. On the top of the saw guide-cylinder
16 is a boxing 19 to receive the back of a saw; 75
and in the lower end of the cylinder 15 is a
screw-plug which forms a closure and also
forms a rest for the cylinder 16.
The turn-table or disk 10 is provided with
a series of perforations 20 near its periphery, 8o
in either one of which a dog may engage for
holding the turn-table as angularly adjusted.
This dog consists of a rod 21, having a down=
wardly-extending portion 22, which extends
through an opening in the plate 2 and is de- 85
signed to engage in either one of said perfo-
rations 20, as before mentioned. The rod is
fulcrumed on a pin 23, removably inserted in
a hole formed in the plate 2, and at the outer
end of this rod is an upwardly-extended por 90
tion 24, having a finger-piece 25 on its top
above the upper edge of the back plate 8.
The dog is held in yielding engagement with
the turn-table by means of a spring 26. When
the turn-table is adjusted to bring the saw to 95
the angle required, it may be held rigidly by
means of a set-screw 27, extended longitudi-
nally of the base and having a screw-thread
engagement with a lug 28, attached to the
under side of the plate 2. zoo
In operation after setting the cylinders 15
and 16 at the angle required for the saw the
turn-table or disk 10 is to be engaged by the
set-screw 27. Then after inserting the saw and
