AN IMPROVED DRILLING MACHINE
Year: 1885

page_text: I, HENRY NOYES of N° 24, George Lane, Lewisham, in the County of Kent,
Ironmonger, do hereby declare the nature of my invention for AN IMPROVED
DRILLING MACHINE to be as follows: -
This invention refers to the ordinary vertical. drilling machines used by most
workers in metal, and is also applicable to similar machines used for drilling
perpendicular holes in wood, stone, slate, glass, bone or any other material.
Its object is to effect a simple and expeditious method of feeding the drill to its
work, or the work to the drill, or to accomplish the same end by causing both drill
and work to approach each other at the same moment and by one action, and
without in either case employing the hands of the operator, which are left free by
my method to attend to the work or actuate the drill. The assistance of a second
person to hold the work which is often necessary when the ordinary drilling
machine is used, can therefore be dispensed with by means of my improved
machine.
A drilling machine of the ordinary kind is composed of four main parts, (1) the
stem or pillar, (2) the upper arm with the drill and its actuating mechanism
whether for steam or hand power, (3) the lower arm with the drill-table or vice,
and (4) the base on which it stands or the clamps or brackets by which it is fixed
to floor, bench, or wall or any two of these.
In my improved drilling machine the stem or pillar is formed hollow, that is of
an iron or steel tube of the requisite strength.
Inside this tube and extending from the floor of the workshop upwards to the
top of the pillar is an iron-bar, on the summit of which is a weight designed to
cause the bar to return to its normal position, after being set in action, and to
counterbalance any tendency to rise which may result from its position.
At the lower end of this bar is fixed a foot lever mounted on a fixed fulcrum, the.
long arm of which lever projects forward to the operator or in any preferred
position while the short arm is attached to the aforesaid bar.
To the summit of the bar is attached a short lever and fulcrum the other end of
which lever is attached to the spindle which holds the drill in such a way that an
upward motion of the bar impels the drill and its mechanism in a downward
direction. In the usual position near the base of the pillar is an iron sleeve, bored
to slide on the said pillar and capable of being adjusted to the height required.

page_text: This sleeve is fitted with a drilling table or vice and is free to revolve in any
direction and is furnished with set pins for fixing when required, but can be
supported by means of a collar connected with the vertical bar, through slots in
the pillar or by set screws, or in any other suitable way, so that it shall when
required, rise and fall with the movement of the vertical bar.
The result is that when the pressure of the foot is applied to the foot lever, the
vertical bar rises in the pillar, carrying with it when desired the sleeve and table,
while at the same time the top lever is set in action and forces down the spindle
and drill, so that a constant and immediate feed is effected, and when the foot
pressure is withdrawn the bar drill and table resume their normal position.
When preferred the pressure may be applied by means of a weight to the end of
the foot lever, or by a powerful spring, or a spring may be used to ensure the return
of the foot lever to its normal position.
The drill will generally be caused to revolve by hand power in the usual way,
but when preferred to be driven by steam or gas or other power, a pulley may be
applied directly upon the spindle itself the spindle forming its fixed vertical axis.
In some sizes and for special purposes it may not be necessary to construct the
double-feed action herein described.
In cases where a single feed action may be deemed sufficient the vertical bar
need not extend beyond the point required for lifting the sleeve and table, the top
lever being dispensed with. Or if preferred the drill may be caused to descend
while the table remains stationary. In either case a single feed will be produced.
Or the connection between the sleeve and the bar may be made optional so that the
same machine may be convertible into either a single or double feed drill.

page_text: I HENRY NOYES of 24 George Lane Lewisham in the County of Kent Iron-
monger do hereby declare the nature of my invention for AN IMPROVED DRILLING
MACHINE and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
A vertical drilling machine constructed to drill holes in iron brass or any other
material made in the form of a hollow pillar through which passes a bar
actuating the feed of the drill which is with its mechanism fixed to the top of the
pillar. This bar is attached to a lever at the foot or in other forms as after
described.
My invention relates to ordinary vertical or horizontal drilling machines used by
most workers in metal and is also applicable to similar machines used for drilling
holes in wood stone slate glass bone or any other material.
Its object is to effect a simple and expeditious method of feeding the drill to its
work or the work to the drill or to accomplish the same end by causing both drill
and work to approach each other simultaneously and by the same action and
without in either case employing the hands of the operator which are thus left
free to attend to the work or in the case of a hand machine to work the machine.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is to be performed.
Fig. I represents a side elevation of an ordinary pillar drilling machine with my
improvements applied.
Fig. II represents a front elevation of the same and
Fig. III is a section thro' pillar and table showing method of securing same.
Similar letters refer to similar parts throughout the several views.
a is a hollow pillar on which are secured the head by the cap c and the table d
the foot lever e is jointed to pillar at fand to the rod g at h so that pressure on i
raises the rod g the cap o forming guide for same and the weight / on pressure
being released brings rod and lever back to their normal position; the rod g is
secured to drill spindle by means of a lever m moving on the fulcrum n so that
the rod g being raised the drill spindle is lowered to its work, the rod g is welded
to flat plate p which fits in slot q in pillar being free to move up & down in same;
the table is formed in two parts, the table proper & and the sleever fitting on
pillar a the said sleeve being secured at any desired height to the plate p by means
of set pins 8. 8. being still free to move up and down on pillar, the table proper d
is provided with collar t fitting on sleeve r being free to revolve on said sleeve and
may be secured at any point by the set pin u
The sleever being secured to plate p and the table proper being secured to
sleever the action of lowering foot lever at i raises the rod and plate p also the
sleeve and table towards the drill at the same time lowering the drill as already
described so that drill and table with work thereon approach each other at the
same time, on pressure being released both returning to their normal position by
means of the weight or if preferred by means of a spring or springs.

page_text: If a single feed action is desired the set pins 88 may be withdrawn from slot q
so as to allow sleeve r to turn on pillar a to which it may then be secured by the
pins 88 leaving the plate p & the rod g free to move up and down apart from table
thus feeding the drill to the work which remains stationary; or the feed motion
may be obtained solely by raising the table and work thereon to the drill in which
case I place a centre against the upper end of drill spindle to take the thrust
thereon instead of connecting it as in Fig. I to the lever m, table and sleeve alone
being secured to the rod g by means of the set pins 8. 8. on the plate p, thus on
depressing the foot lever at i the table only is raised toward the drill, machines of
this class may be driven in the ordinary way by bevil gearing, or the driving
pulley when being driven by power may be attached to the drill spindle thus
driving direct.
These improvements are applicable to machines driven by hand or power and
to machines for drilling holes in a vertical or horizontal direction or at any angle.
Having now described the nature of my invention and the manner in which the
same is to be performed I wish it to be understood that I claim as my invention
of "Improvements in drilling machines
"
First.. The mode of producing the feed by means of a foot lever raising the table
and lowering the drill either simultaneously or separately.
Second. The general form and construction of the machine as described.
In witness whereof I the said Henry Noyes have hereunto set my hand and
seal this 4th day of March in the year of our Lord one thousand eight
hundred and eighty six.
