Improvements in and Appertaining to Radial Hand Drilling Machines.
I, JAMES GLOVER of Hyndburn Works, Hindle Street, Accrington, in the County
of Lancaster, Machinist, do hereby declare the nature of this invention to be as
follows:-
This invention relates to radial hand drilling machines, and consists of an improved
construction of the same, whereby they will drill in any position, either vertically or
horizontally. The drill base is formed perfectly flat, so that it can be bolted to a
table or to the wall. It is provided with a footstep or socket, into which fits a vertical
standard or spindle. On this vertical standard is a boss which slides on a key and
is adjustable to any position on the standard by a set screw.
This boss is formed with a flat disc, on the face of which is an annular recess
dovetailed or undercut on its inner edge.
The frame, carrying the drill spindle, has also a flat face, which has two bolts formned
with heel shaped heads, which fit into the under cut recessed annular channel on the
disc of the boss in such a manner as to be capable of sliding round any portion thereof,
but can only be removed from one point, and that only by tilting the bolts previous
to their withdrawal.
In this way the drill is capable of being moved radially upon the surfaces of the two
disc faces in a vertical direction, whilst the adjustable boss fixed to the vertical standard
permits of its free movement radially in a horizontal direction.

Improvements in and Appertaining to Radial Hand Drilling Machines.
I JAMES GLOVER of Hyndburn Works, Hindle Street Accrington, in the County
of Lancaster, Machinist, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to radial hand drilling machines, and consists of an improved
construction of the same, whereby they will drill in any position, either vertically or
horizontally.
The drill base is formed perfectly flat, so that it can be bolted to a table or to the
wall. It is provided with a footstep or socket into which fits a vertical standard or
spindle. On this vertical standart is a boss which slides thereon and is adjustable to
any position on the standard by a set screw,

page_text: This boss is formed with a flat disc, on the face of which is an annular recess
dovetailed or undercut on its inner edge.
The frame, carrying the drill spindle, has also a flat face, which has two bolts
formed with heel shaped heads, which fit into the undercut recessed annular channel
on the disc of the boss in such a manner as to be capable of sliding round any portion
thereof but can only be removed from one point and that only by tilting the bolts
previous to their withdrawal.
In this way the drill is capable of being moved radially upon the surface of the two
dise faces in a vertical direction while the adjustable boss fixed to the vertical
standard permits of its free movement radially in a horizontal direction.
In the accompanying drawings, Fig. 1 represents my improved radial hand drilling
machine with the drill spindle in a vertical position. Fig. 2 is a similar view with
the drill spindle in a horizontal position.
A is a drill base, which may be bolted to a wall or bench by the bolts B. Cast to
this base is a footstep or socket C, into which fits the vertical standard D firmly secured
in position by the set screw E.
Sliding on this vertical standard D is adjusting boss F, which is adjustable to any
position on the vertical standard by the set screw G, which when tightened firmly
secures the said boss upon the vertical standard. Formed with this boss is a flat
disc H, on whose face is an annular recess J dovetailed or undercut on its inner
edge.
The frame K carrying the drill spindle P has also a flat face, and is provided with
two bolts I and M having suitably shaped heads N, which fit into the undercut
recessed annular channel J on the disc of the boss F in such a manner as to be capable
of sliding round any portion thereof, but can only be removed from one point, and
that only by tilting the bolts previous to their withdrawal. As, however, the bolts
are tightened upon the flat face O of the drill frame by nuts, it is impossible for
them to leave their true position in the annular channel, when the drill is being
.worked.
From what has already been said of my invention, it will be evident that the drill
spindle P is capable of being manipulated radially in any direction either vertically
or horizontally.
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
The improved arrangement and construction of radial hand drilling machines, and
combination of parts, substantially as described and shewn in Figs. 1 and 2.
