IMPROVEMENTS IN BRACES SUITABLE FOR USE' BY JOINERS AND OTHER MECHANICS
Year: 1885

page_text: I THOMAS WILLIAM NEWEY Auger and Gimlet Maker 39 Allison Street Digbeth
Birmingham in the County of Warwick. do hereby declare the nature of my
invention for IMPROVEMENTS IN BRACES SUITABLE FOR USE' BY JOINERS AND
OTHER MECHANICS and in what manner the same is to be performed, to--be
particularly, described and ascertained in and by the following statement:—
This invention consists of an arrangement of parts for the purpose of readily
fastening bits of any ordinary pattern in braces of any ordinary pattern with the
capability of quick and ready removal.
In carrying out my invention I proceed in the following manner
At a suitable and convenient part of the brace near to the usual opening formed
therein to receive the bit: I provide a slot, pierced by preference clear through the
neck, or body of said brace.
I next provide a disc of such a diameter that when placed in the slot, it will
project through each side a sufficient distance to enable any person using the brace
to rotate the disc by thumb and finger pressure, I pierce a central hole in the said
disc I then pierce a hole of corresponding diameter in the neck of the brace in
such a manner that when the disc is placed in the slot a sutable stud or axial pin
can be passed through the material on one side the slot thence, through the disc
thence through the material on other side of slot, thus the disc is secured in the
slot to rotate on the axial pin or stud.
I make my disc circular with the edge rounded and milled.
I remove a portion of the disc to leave an opening in its periphery preferably of
a rectangular shape I then provide in all the shanks of all the bits I intend to use
with my improved brace a slot to receive the disc as hereinafter more fully
explained.
In using my improved brace I rotate the disc until the rectangular opening is
lineable with the opening provided in the brace to receive the bit I then take up
one of the bits and pass the shank of it into the usual opening provided to receive
it taking care to place it therein with the slotted side towards the disc In placing
the shank of the bit in position the end would pass through the rectangular
opening in the periphery of disc until when the shank of the bit rested and fitted
in its bearings the slot would be lineable with the face of disc.

To secure the bit it would be merely necessary to rotate the disc with the thumb
and finger by that means the opening in the face of said disc would move away
from shank of bit and the true periphery of the disc would pass into the slot in the
bit, thus locking or securely the said bit ready for use.
To unlock it the disc would be rotated by the thumb and finger until the
rectangular opening in its periphery was moved lineable with the hole or opening
in brace..
I will now proceed to describe with reference to the accompanying drawings the
manner in which the various parts constituting my invention are put together.
Figure 1 represents an ordinary pattern brace made on my improved principal.
Figure 2 represents a detailed view enlarged showing the bit placed in position
and the disc turned with the periphery filling the slot in the shank of bit and thus
securing the said bit in position.
Figure 3 is a section of fig 2 at A B.
Figure 4 is a plan of figure 2 in the direction of the arrow.
Figure 5 is a plan of the disc.
Figure 6 is an elevation of the disc.
Figure 7 is a side elevation of the shank of bit.
Figure 8 is a front view of the shank of bit showing the slot carried clear accross
the said shank.
a Figure 2 is the slot provided to receive the disc; b is the disc in position
locking or securing the bit; c is the stud or axial pin whereon the disc rotates; d is
the shank of the bit provided to receive the periphery of disc.
f Figure 3 shows the slot in disc moved in a position to allow the bit to be put
in or taken out.
g Figure 4 shows in dotted line the periphery of disc in position to lock the bit.
g shows the opening in periphery turned away from bit.
I by preference make my improved brace out of iron with the slot cast or
punched out.
I do not confine myself to iron as the brace can be made out of any suitable
material.
"
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st The making of a brace suitable for use by joiners and other mechanics with
a disc revolving on an axial pin near the ordinary passage usually provided to
receive the shank ends of bits, the said disc having an opening in its periphery to
allow the shank ends of bits to pass through the said opening until a slot provided
in the shanks of bits becomes lineable with the faces of disc enabling the disc to be
rotated on its axial pin until its periphery enters the slot in shank of bit to lock or
secure it to the brace.
2nd The making of the shank ends of brace-bits with a slot or opening expressly
provided to receive the periphery of disc hereinbefore mentioned in claim 2.
3rd The combination of a slot in the shank of a brace-bit with the periphery of
a disc connected to a brace.
