Improvements in Machines for Boring, Cutting, and Forming Holes
for Handles and other purposes in Boxes, or for Shaping Handles
on Pieces of Wood.
I, FREDERICK WILLIE BROCK of Albert Road, St. Philips Bristol Box
Manufacturer 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:-
This invention relates to a machine for boreing, cutting and forming handles or
other holes in boxes and in pieces of wood to be used for parts of boxes or for
forming handles on pieces of wood for any purpose.
The machine is constructed in such a manner that the handles or holes are cut or
formed in any thickness wood without material alteration of parts and in such
positions as to be best suited for the purpose intended.
The machine is arranged to work with relatively small power.
In the accompanying drawing
Fig. 1. is a plan of the machine.
Fig. 2. is a sectional elevation of the spindle and frame.
Fig. 3. is a cutter for use with machine.
The machine rests upon & is supported by a table or frame A upon which is a
top or bed B. Underneath the top B is a vertical spindle C driven by a belt
actuated from a shaft with fast & loose pullies, not shown on the drawing. This
spindle C is fixed in bearings D attached to a frame E which slides or moves
vertically and is adjusted for wear by the slides Fattached to the framing A. This
frame E is raised by the lever G working upon the pivot. H. Upon the top of the
bed B is a frame I fixed to turn on the pivot K and traversing the distance allowed
by the slot L & prevented from rising by the bolt or stud M. Attached to the
frame is a bed N constructed to allow a cutter attached to the spindle to pass
through it at the slot O, and having an adjustable back guide P and guides Q
which latter are worked or adjusted by a screw R as to automatically centre upon
the slot O by being turned by the hand wheel S. The guide P is adjustable by
means of a screw & not to & from the slot O. A knuckle joint is attached to J at T
and to this joint is affixed a holder U in such a manner as to allow it to be lifted
up as on a hinge or turn on one side. This has also an adjustable jaw V working
to & from the slot O by a screw or other adjustment and is terminated in a handle W
which is over a similar handle forming part of J. Attached to the spindle C is a
suitably formed cutter (Fig. 3.) for horing, cutting, rounding & forming the handle
holes.
The method of forming the handle, either on the edge of a piece of board or by
a suitably shaped & finished hole is as follows:
The holder U is lifted up & the piece of wood to be operated upon is placed
underneath it, and upon the frame J the back guide P being so adjusted as to bring
the edge of the board at the correct distance from the slot 0 so as to allow the
cutter (Fig. 3.) or other suitably shaped tool to operate either on the edge
or some distance in (in the case of a hole) as may be required; and the jaws Q are

adjusted so as to bring the ends of the board equidistant from the slut 0.
case of boards being of greater length than the jaws Q will allow to go
between them, the jaws may be removed & other suitable gauges be fixed. After
the boards has been centered by the jaws Q & adjusted by the guide P' the holder U
is turned over on the board & the guide V adjusted to the width, the handle W
being then vertically over that forming part of the frame J. The machinery being
put in motion the spindle C to which the cutter is attached revolves & the operator

then places his foot on the lever G & rises the spindle & cutter vertically, the
cutter passing through the slot O & boring a hole in the wood thus held or secured
over it, or if required & so adjusted forming the edge of the board. The frame J &
the holder U are both gripped by the operator by the handles at W & with the
piece of wood held between them moved in the direction of the arrows to the length
of the slot L the cutter being all this time rotating & held up to the work by the
lever G. The bolt or stud M may be varied as to shorten the distance the "slot L
may traverse & this bolt or stud also holds the frame. J'down to the table B &
prevents it rising with the pressure of the cutter upwards. After the hole or handle
has been formel, the lever G is released & the spindle C & the cutter attached to
it falls underneath the table, but need not be made to cease revolving. If it is so
required the holder U is lifted & the wood being operated upon is turned upside
down & the operation repeated, thus removing the arris from both sides & leaving
the edges rounded.
The machine may be varied by removing the pivot K & the bolt M & substituting
a rack or screw movement for the swinging or pivoting.
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.
(1) The form of cutter shown as Fig. 3. which is in itself (a) a boring tool, (b) a
slotting tool & (e) a arrising or rounding tool.
(2) The frame & holder constructed to move in such a manner as to form the
handle either as a hole or on the edge slightly circular to fit the hand & of such
length as required.
(3) Rounding or taking the arris off, either on both edges of the handle & on
both sides.
(4) Adjustment so as to readily center the wood.
(5) Rising & falling spindle.
