I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
Hitherto the mode of manufacturing panel doors has generally been by mortise
and tenon, cach mortise and each tenon having to be made separately. By this
invention, it is proposed to employ dowels or pins, thereby effecting a considerable
saving in labour, as it is possible, by this apparatus, to make several dowel holes at
one operation, whereas, in the case of doors hitherto made, each mortise and each
tenon had generally to be made separately.
In carrying out the invention, a suitable number of dowels or pins are used,
passing through the centre of the side or standing rails, and extending into the
bottom, lock and top rails in such a way as to bind the individual parts of the frame
firmly together. The dowels are grouped together in rows or in other suitable
manner. The size, length, and number of dowels may vary according to the size
of the door.
The apparatus for drilling the dowel holes comprises a frame upon which two
parallel shafts are mounted at a suitable distance apart. Mounted upon said shafts
are a suitable number of boxings (preferably three on each shaft) each of the under
parts of which is bolted around said shafts. The upper parts of each form bearings
for driving shafts and rods located at right angles to the parallel shafts aforesaid.
The rods are stationary in the respective boxings, and answer the purpose of slides
or carriers for sliding frames, adapted to carry a suitable number of drill spindles.
These rods preferably extend from the boxings on one of the parallel shafts to the
boxings on the other parallel shaft, thus coupling them together in pairs. The said
sliding frames are adapted to bolt around the driving shafts and rods aforesaid, and
this keeps them in place and also serves to keep the rods from spreading or moving
when the pinions, hereafter referred to, are in motion. The drill spindles or the
part of them which revolves in the bearings are made tapering, so that, when they
wear loose, they can be tightened by drawing them back. Right and left hand
auger or drill bits are fastened in the ends of the drill spindles by set screws.
Pinions are keyed to the drill spindles and mesh into each other, and are driven or
kept in motion by a toothed wheel mounted on the driving shaft. This toothed
wheel slides or is drawn forward and slid back together with the pinions, bearings,
drill spindles and augers or drills. It is kept from turning, while being allowed to
slide, by a key. To each of the bearings aforesaid is fastened a rod, and to the end
of this rod is fastened a toothed rack, which engages pinions on a suitable shaft.
By turning the shaft by a hand wheel in one direction, the bearings, pinions, drill
spindles and augers or drills are drawn forward, and, by turning in the other
direction, slid back. Each driving shaft is provided with a driving pulley, which
can be driven from a main or counter shaft either above or below. The boxings
can be moved to any desired part of parallel shafts by loosening bolts below.
When in use, two of these machines may be adapted to work facing each other
and at a distance apart to allow a door to pass between on a table or rollers.

page_text: When the door has advanced to a proper distance, it is grasped by cramps and all
joints tightened; the next movement is to turn the hand wheel and adjust the
position of the augers or drills so as to bring them into proximity to the parts to be
operated upon. The position of the augers on the twin machine can also be
controlled by the same hand wheel.
By this machine, all the dowels' holes on one side of a door or doors can be
simultaneously drilled.

A communication from abroad by HENRY VALENTINE EDMONDS, of New
Westminster, British Columbia, Saw Mill Proprietor.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, C, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil 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 :—
The invention relates-mainly to the manufacture of panel doors and to apparatus
applicable for use in such manufacture. The improved method and apparatus-are.
however applicable to the manufacture of doors other than the above class.
Hitherto the mode of manufacturing panel doors has generally been by mortise
and tenon, each mortise and each tenon having to be made separately. By this
invention dowels or pins are employed instead of mortises and tenons thereby
effecting a considerable saving in labour, as it is possible by this apparatus to make
several dowel holes at one operation, whereas in the case of doors hitherto made
each mortise and each tenon had generally to be made separately.
In carrying out the invention a suitable number of dowels or pins are used
passing through the centre of the side or standing rails and extending into the
bottom, lock and top rails in such a way as to bind the individual parts of the frame
firmly together. The dowels are grouped together in rows or in other suitable
manner. The size, length and number of dowels may vary according to the size of
the door.
The apparatus for drilling the dowel holes may be described as follows, reference
being had to the accompanying drawings, in which
Figure 1 is a perspective view of the improved door doweling machine.
Figure 2 is a vertical longitudinal section showing one of the boring heads in
elevation.
Figure 3 is an enlarged cross section on line Figure 2, and
Figure 4 is a detail.
AA are two stands connected by tie rods a a to form a machine eud or frame,
two such ends being used. A' A' are two stands carrying the setting mechanism.
In the stands A. are secured two transverse rods B upon which the boxes C are
adapted to slide, for the purpose of being adjusted thereon in any desired position
or distance from each other and secured in position by tightening the cap bolts of
the boxes. The boxes Care compound and besides having bearings for the rods B,
have journaled in them the shafts D, and have also secured in them the ends of the
guide rods F. One of these bearings is shown separately in Figure 4. The
shafts D are each provided with a pulley D', which is driven by a strap D from
above or below, as shown in Figure 2. The shafts D have each a key bed d nearly
their whole length, and carry each a pinion E adapted to slide thereon and be

page_text: rotated by a key fast on said pinion and engaging the groove or key bed. GG are
the two blocks or ends of a carriage adapted to slide upon the guide rods F. In
these are journaled a series of spindles G₁, cach having mounted upon it a
pinion G, all of which in the series gear together and rotate said spindles, the
central one being geared into the pinion E as shown in Figure 3. Each spindle G'
is also provided with a drill socket g' for the insertion of a bit H. The bits are
made alternately right and left handed and may be fastened in the sockets g' by
set screws as seen in Figure 2. The bearings of the spindles G in the blocks &
may be made tapering so that wear may be readily taken up. The ends G are
connected below by a rod or bar I which extends forward beyond the outer box C
on which it is carried and terminates in a rack I gearing into a pinion J¹ which is
mounted upon a shaft J provided with a hand wheel J" and journaled in the
stands A¹
By turning the hand wheel J" and thus rotating the shaft J in one direction or
another, the carriages G are moved on the guide rods F forward or backward, the
pinions E moving with their carriages and sliding on their shafts D, the shafts D
may be set any distance apart on the rods B and there may be any number of them
that can be contained on the length of said rods. Each carriage G G¹ may also be
constructed to carry any number of spindles desired. Two machines may be placed
opposite cach other with one common propelling shaft J between them. The parts
to be doweled aro placed in position across the rods F the joints having previously
been firmly tightened by cramps. The bits H are now propelled towards and into
them by turning the hand wheel J" while the shafts D, and with them the bits H,
are rotating.
By the above machine all the dowel holes on one side of a door can be
simultaneously bored.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. In a machine for doweling doors as described, the combination of a pair of
parallel guides B, supported on suitable frames, one or more opposing pairs of
bearing boxes C sliding on said guides, guide rods F rigidly connecting each
opposing pair of boxes, a rotatable shaft D journalled in each opposing pair of boxes,
a carriage G G sliding on each set of guide rods F, a series of parallel drill
spindles mounted one or more on each of said carriages, gearing connecting the drill
spindles of each carriage the one with the other and with a pinion rotatable with
the shaft D and movable with the carriage, and means for rotating the shafts D
and sliding the carriages G G to and fro, substantially as described.
