PROVISIONAL SPECIFICATION.
Improvements in Morticing and Boring Machines.
I JOHN WILD of Falcon Iron Works Oldham in the County of Lancaster
Engineer, do hereby declare the nature of this invention to be as follows:-
My improvements consist in the arrangement of a machine for morticing and
boring timber so that it can be worked by either hand or power as may be desired.
On a suitable frame work a sliding head which carries the chisels and bits is
mounted to which a toothed rack is secured. Further back on the same frame
another toothed rack is fitted and so arranged that it can be secured to the frame
of the machine or to slide up and down as may be desired. Between these two
toothed racks and gearing into them and mounted on a stud carried by a hand-
lever but so arranged that it may be secured rigidly to the lever or left perfectly
free to revolve as may be desired is a spur wheel so that when it is required to
mortice by hand all that is necessary is to secure the spur wheel to the lever and
the rack to the frame then by moving the hand lever up or down a corresponding
motion will be given to the head.
For morticing by power the spur wheel must be left free to revolve on the stud
and a reciprocating motion given to the tooth rack by means of a crank or other device
while the end of the hand lever is coupled by a connecting rod to the frame of the
machine and the other end held rigidly so that the reciprocating motion of the
rack may be communicated to the head through the spur-wheel. By lowering or
raising the outer or handle end of the hand lever the head may be brought to
strike lower or higher as the case may be.
When it is desired to bore by hand a pair of bevel wheels are fitted into the
head one on the spindle and the other geared into it and so arranged that it can be
turned by a handle. By this arrangement the same spindle is used for both
morticing and boring.
To bore by power I extend the spindle upwards and fix the bevel wheels in a
suitable bracket at the top of the machine so that the spindle which is slotted may
slide freely through its wheel on a feathered key and the other may be driven by
a belt through a suitable shaft and pulley.
COMPLETE SPECIFICATION.
Improvements in Morticing and Boring Machines.
I, JOHN WILD of Falcon Iron Works, Oldham in the County of Lancaster,
Engineer, 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 :-
My improvements consist in the arrangement of a machine for morticing and
boring timber, so that it can be worked by either hand or power, as may be desired.
On a suitable framework A a sliding head b, which carries the chisels and bits c is
mounted, to which a toothed rack d is secured. Further back on the same frame A
another toothed rack e is fitted, and so arranged that it can be secured to the
frame A of the machine or slide up and down as may be desired. Between these
two toothed racks d and e and gearing into them and mounted on a stud f, carried
by a hand lever g but so arranged that it may be secured rigidly to the lever g,
or left perfectly free to revolve on the stud f, as may be desired, is a spur wheel h,
so that when it is required to mortice by hand all that is necessary is to secure
Sprins ei

page_text: the spur wheel h to the lever g and the rack e to the frame A and loosen the stud
in the framework A. Then by moving the hand lever g up or down a corresponding
motion will be given to the head b.
For morticing by power the spur wheel h may be left free to revolve on the
stud fand a reciprocating motion given to the toothed rack e by means of a crankj
and connecting rod k or other device whilst the end of the hand lever g is coupled
by a connecting rod & stud p to the frame A of the machine and the other that
is the handle end held rigidly so that the reciprocating motion of the rack e may be
communicated to the head b through the spur wheel h. By raising or lowering
the handle end of the lever g the head carrying the chisel c may be brought to
strike lower or higher as the case may be.
When it is desired to bore by hand a pair of bevel wheels m m are fitted into the
head b one on the spindle o and the other geared into it and so arranged that it can
be turned by a handle p. By this arrangement the same spindle is used for both
morticing and boring.
To bore by power I extend the spindle o upwards and fix the bevil wheels m, m, in a
suitable bracket at the top of the machine so that the spindle which is slotted or
grooved may slide freely through its wheel on a feathered key and the other wheel
may be driven by a belt through a suitable shaft and pulley.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The general arrangement of a morticing and boring machine which may be
worked by either hand or power as may be desired and having two parallel racks
with a wheel working between them for the purpose described and illustrated by
the accompanying drawings.
