This Invention refers to Improvements in self feeding hand power drilling machines
and relates. Firstly To an arrangement by which the friction can be regulated to
suit the various pressures required to work the drill whilst the drill is in motion.
Secondly In an arrangement by which the handle can at once be placed at any
desired angle for convenience in working without removing any portion of the
machine.
The first part of the Invention is effected as follows Upon the spindle I place a
disc carrying a flat spring bearing upon a catch which catch acts upon a cam upon
By this

arrangement turning the handle of the machine causes the cam to work the drill and
reversing the handle at once raises the drill from its work by reason of the catch
holding the cam.
Or instead of the flat spring I can use a spiral spring contained in a case and
arranged to bear upon the catch which catches into the cam as above described.
The second part of this Invention is effected by forming the head of the machine
to swivel upon a collar upon the supporting arm of the machine so that the head
carrying the wheels and handle can be set at any desired angle to the arm of the
machine and can be fixed in such position by a set screw bearing into a groove in the
said collar.

I, JOHN DEACON of 98 Pritchett Street Birmingham in the County of Warwick
Engineer and machinist, do hereby declare the nature of my said invention for
IMPROVEMENTS IN DRILLS, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, reference
being had to the accompanying drawings and to the letters and figures marked
thereon:-
This invention refers to improvements in self feeding hand power drilling machines,
and relates firstly to an arrangement by which the friction can be regulated to suit
the various pressure required to work the drill whilst the drill is in motion.
Secondly in an arrangement by which the handle can at once be placed at any
desired angle for convenience in working without removing any portion of the
machine.
I will now describe the invention Referring to the accompanying Drawings in
which similar letters refer to similar parts. Fig. 1. is a view of the machine, Figs. 2
and 3 & 3 plans of two forms of the disc, (b), Fig. 4 a plan of the vice and stand.
The first part the invention is effected as follows.
Upon the feeding screw (a) I place a disc (b) carrying a flat spring (c) Fig. 2
bearing upon a catch (d) which catch (d) acts upon a cam (e) fixed upon the
spindle (k) passing through the feed screw (a) as illustrated in the enlarged drawing
Fig. 5. the pressure of this flat spring (c) being regulated by a set screw (f) Fig. 2.
Or instead of the flat spring (c) I can use a spiral spring (9) Figs. 3 and 3 con-
tained in a case (h) and arranged to bear against the catch (d) which catches into the
cam (e) as above described.
Turning the handle (x) of the machine works the bevelled gearing (1) and (¹) and
revolves the spindle () carrying the drill (y). The cam (e) being fixed to the
spindle (k) revolves with it, the feed being supplied and regulated by the screw (h)
bearing upon the catch (d) and causing it to press upon the cam (e) as illustrated
in Fig. 3 thereby giving the feed during the revolution of the cam from (e¹) to (²).
Figs. 3 and 2 shewing the parts when the feed is off. The feed of the drill being thus
obtained in either of the above arrangements by the action of the bevelled gearing
and regulated by the set of the screw (f) or screw (g) upon the cam (e).
The second part of this invention is effected by forming the head (2) of the machine
to swivel upon a collar () upon the supporting arm (w) of the machine so that the
head () carrying the cog wheel () and handle (x) can be set at any desired angle to
the arm (w) and can be fixed in such position by a set screw bearing into a groove in
the collar ().
When desired I can fix
illustrated in Fig. 4, below
vice is required to be used
at the foot of the machine a vice which arrangement is
the table (1) which table (1) will be removed, when the
This vice consists of the screw threaded bar (m) working

page_text: within the tube (0) Figs. 1 and 4 through a nut or box (u) which is fixed to the
underside of the foot (A) the tube (0) being slotted out to work over the nut or
box ().
The screw threaded bar (m) has upon it the collar (p) against the end of the tube (o)
so that rotating the screw threaded bar (m) by means of the handle (q) attached to
the collar (p) the jaw () fixed upon the tube (o) is caused to travel with the tube
and thus to open and close against the stationery jaw (s).
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,
Firstly the arrangement of the mechanical parts substantially as herein set forth
and specified by which the friction can be regulated to suit the various pressures
required to work the drill.
Secondly constructing the drill so that the handle can be at once placed at any
desired angle for convenience in working substantially as herein set forth and specified
without having to remove any portion of the machine.
Thirdly the application of a vice at the foot of the drill substantially as herein set
forth and specified.
