Improvements in Routing Machines.
We, EDWARD KNIGHTS, Engraver, of No. 39, Effra Road, Brixton, and HENRY
CAPSEY, Engineer, of No. 54, Stamford Street, Blackfriars, both in the County of
Surrey, do hereby declare the nature of this invention to be as follows:-
The invention relates to improvements in routing machines, by means of which, a
more convenient and practical machine is produced than heretofore.
For this purpose, instead of causing the beam or support for the head to extend
right across the machine as heretofore, we, according to our invention, dispense with
such beam and mount the head upon an arm projecting from a standard at one side of
the machine and we thus allow the light to have unobstructed access to the bed of the
machine and consequently to the work being executed thereon, whereby, the necessity
for the use of gas or other artificial light during the day time is obviated.
In order to steady the arm, we form on, or fix to, the end thereof, a vertical offset
or pillar, which is, by an adjustable tie bar, connecting with a corresponding pillar or
standard at the side of the machine.
At the end of the arm is fixed a dovetail bar, upon which the head is fitted with
capability of sliding borizontally thereon and a set screw is provided, by means of
which, the head may be fixed in any desired position.
The drill spindle is mounted in bearings formed in two arms or brackets of a frame
which is fitted into a dovetail groove in the head with capability of vertical movement
therein and this frame together with the drill spindle is normally held in its uppermost
position by means of a weight or spring arranged in or at the back of the standard by
which the arm is supported and acting upon the dril! frame through suitable
connection or connections passing through a way or ways formed in the arm for that
purpose.
The frame carrying the drill spindle is depressed and the drill is brought down to
its work by a lever which may be operated directly by hand or connected with a
treadle and operated by foot and the same is arranged to act on one end of a cross
lever which passes through an eye or loop upon the drill frame the opposite end
thereof being pivoted to the head. When the first mentioned lever is mounted upon
a fixed part of the frame, the levers are so arranged that they may be disconnected to
allow of the adjustment of the head.
The necessary rotary motion is communicated to the drill spindle by means of a
leather driving band, which passes around a pulley fixed upon the main shaft of the
machine and around a pulley of smaller diameter fixed upon the drill spindle and the
tension of this leather band is adjusted as required by means of the horizontal
movement of the head.

Improvements in Routing Machines.
We, EDWARD KNIGHTS, Engraver, of No. 39, Effra Road, Brixton, and HENRY
CAPSEY, Engineer, of No. 54, Stamford Street, Blackfriars, both in the County of
Surrey, do hereby declare the nature of this invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the following
statement:
Our said invention relates to improvements in routing machines, by means of which,
a more convenient and practical machine is produced than heretofore.

page_text: Upon the end of the arm e' is formed or fixed a dovetail bar c* upon which the
head d is fitted with capability of sliding horizontally thereon and transversely of the
machine for purposes of adjustment and a set screw is provided which serows
through the head d. and abuts against the dovetail bar c* by which means the head d.
may be fixed in any desired position.
The drill spindle e. is mounted in bearings formed in two arms or brackets f¹ of a
frame or plate f. which is fitted with capability of vertical motion in a vertical dovetail
groove or slot formed in the head d. and is indirectly connected as hereinafter
described with an arm or lever g. which passes through the arm e¹ and is mounted
with capability of rocking upon a stud or axis g' fixed to the arm c¹.
One end of the rocking
arm or lever g. passes through an opening in the standard c.
and is, by a link g², pin-jointed thereto, connected with a weight g³ (or it might be a
spring) working in a guide slot a' in the frame a.
Or, the lever g. might be otherwise connected with the weight g³; for example, by
a cord or chain.
By these means, the drill frame f. together with the drill spindle e. is normally held
in its uppermost position, but is capable of being easily depressed in order to bring
the drill e. down to its work.
The drill frame or plate f. is depressed and the drill e. is brought down to its work
by means of pressure applied to the end g* of the lever g. either directly by hand or
through a connection ** from a treadle and the necessary motion is communicated
from the lever g. to the drill frame f. through a cross lever which is provided with
a slot through which passes a headed stud ffixed to the frame f. and one end of
which lever is mounted with capability of longitudinal movement in a loop or frame g*
fixed to the lever g. in order to allow of the adjustment of the head . whilst the
other end is mounted with capability of turning upon a stud or axis d² fixed to the
head d.
The necessary rotary motion is communicated to the drill spindle e. by means of a
leather driving band . which passes around a pulley fixed upon the main shaft i.
of the machine and around a pulley e of smaller diameter fixed upon the drill
spindle e. and the tension of the feather band h. is adjusted as required by moving the
head d. horizontally upon the dovetail bar c* of the arm c³.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to he performed, we declare that what we
claim is :-
1. In a routing machine, an arm o' projecting from the side frame a. of the
machine adapted to support the head d. and connected parts, in manner substantially
as herein shown and described and for the purpose stated.
2. In a routing machine, the combination of an arm projecting from the side
frame a. of the machine adapted to support the head d. and connected parts, a pillar c³
upon the arm c, a corresponding pillar ct upon the opposite side of the machine and
an adjustable tie bar c connecting such pillars all in manner substantially as herein
shown and described and for the purpose stated.
3. In a routing machine, an arm c¹ forined with a way therethrough and projecting
from the side frame of the machine in manner substantially as herein shown and
described and for the purpose stated.
4. In a routing machine, the combination of an arm c¹ projecting from the side
frame a. and formed or provided with a transverse bar c* and a head d. formed to fit
such bar with capability of horizontal adjustment thereon in manner substantially as
herein shown and described and for the purpose stated.
5. In a routing machine, the combination of an arm c¹ projecting from the frame a.
and formed or provided with a transverse bar c", a head d. formed to fit such bar
with capability of horizontal adjustment thereon, a drill frame f mounted upon the
head d. with capability of vertical movement, a weight g³ or it might be a spring
connected with the lever g. and through the cross lever f² acting to normally retain the

page_text: drill frame
in its uppermost position; the levers g. and f2 serving to depress the
frame and bring the drill down to its work all in manner substantially as herein
shown and described and for the purpose stated.
