like.
I, JOHN UNWIN, of 12, Clifton Road, Maida Vale, in the County of London,
Cabinet Case Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in machinery for carving and moulding
wood and the like and has for its object to provide a machine which is more simple
in construction and which can perform work more quickly than such machines as
now generally used.
According to my invention. I provide a bed to which are secured a number of
uprights for receiving the driving spindle for the cutters and a guide spindle
secured to a sliding block. This sliding block is provided with means such as a
frame actuated by a screw working in one of the uprights whereby it can be moved
longitudinally on the bed and also with guide bars in which slides a frame for
gripping the work. The guide bars are provided with means whereby they can be
raised and lowered and also with means for increasing or diminishing the distance
between the bars.
The sliding frame is advantageously actuated by means of a screw and is so
constructed that it can be adjusted to suit work of varying dimensions.
In connection with the sliding block I provide a plate adapted to be hinged to
the said sliding block on hinges which can be adjusted vertically and which plate
can be held at any inclination by means of an adjustable stop. The plate is
provided with a slit for the passage of the cutter and with a gauge and is designed
to hold work to be bevelled, mitred or the like.
My plate is advantageously formed of a frame in which is fitted a face plate to
which gauges can be secured when the plate is to be used for moulding purposes.

Improvements in Carving and Moulding Machinery for Wood and the
like.
I, JOHN UNWIN, of 12, Clifton Road, Maida Vale, in the County of London,
Cabinet Case Maker, do hereby declare the nature of this invention and in what
[Price 8d1

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to improvements in machinery for carving and moulding
wood and the like and has for its object to provide a machine which is more simple
in construction than ordinary machines of this type and by means of which work
can be performed more quickly than with such machines as now generally used.
According to my invention I provide a bed to which are secured a number of
uprights for receiving the driving spindle for the cutters and a guide spindle
secured to a sliding block. This sliding block is provided with means such as a
screw whereby it can be moved longitudinally on the bed and also with guide-bars
forming a frame in which slides a second frame for gripping the work. The guide-
bars are provided with means whereby they can be raised and lowered.
The sliding frame is advantageously actuated by means of a screw and is so
constructed that it can be adjusted to suit work of varying dimensions.
In connection with the sliding block I provide a plate adapted to be hinged to
the said sliding block on hinges which can be adjusted vertically and which plate
can be held at any inclination by suitable means. The plate is advantageously
formed of a frame in which is fitted a face plate to which gauges can be secured
when the plate is to be used for moulding purposes, and which can provide a slit
for the cutter or saw.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawings, in which:-
Figure I is a side elevation of a wood carving and moulding machine constructed
according to my invention:
Figure 2 is a front elevation of the sliding block shewn in position upon the
bed plate:
Figure 3 is a section on the line 3-3 Figure 2:
Figure 4 is a section on the line 4-4 Figure 2:
Figure 5 is a front elevation of the hinged plate:
Figure 6 is a plan of the same:
Figure 7 is a section on the line 7-7 Figure 5:
Figure 8 is a section on the line 8--8 Figure 5 the said section being drawn to
a larger scale; and,
Figure 9 is a side sectional elevation of the sliding block and hinged plate
arranged as a saw bench.
a is the bed of the machine and b, b, b the uprights fitted thereto. is the
driving spindle for the cutter or saw (a cutter is shewn at d Figure 1) the said
spindle c being provided with pulleys e, e for driving purposes. f is the sliding
block arranged upon the bed a. g is the guide spindle attached to the said block
and arranged to be supported in one of the uprights b, and is a set-screw by
means of which the spindle 9 can be secured in any position in the said upright b.
i is the screw for longitudinally adjusting the position of the sliding block f
upon the bed a, the said screw passing through a nut on the underside of the
sliding block and being provided with a hand-wheel k.
1, are the guide-bars forming a frame, the said frame being provided with
lugs, through which pass spindles f, f rotatably mounted in the sliding
block f and screw-threaded at their upper ends, the upper lugs 1, being also
internally screw-threaded to receive the screw-threaded spindles f, f¹. By turning
these spindles f¹, f¹ therefore it will be obvious that the frame is caused to slide
up or down upon the face of the sliding block f. m is the sliding frame for
gripping work to be carved which frame slides horizontally between the guide
bars 7, the horizontal movement of the said frame m being effected by means of
the screw n which is provided with a hand wheel n¹ and passes through a nut o
having a pin o¹ which engages in a vertical slot m¹ in the frame m.
construction it will be obvious that by turning the hand wheel n¹ the nut o and
With this
therefore the frame n will be caused to move horizontally in the frame 1.

page_text: For gripping the work in the frame m I provide the latter with lateral
screws m², m² and with a plate or bar m³ which can be adjusted vertically by
screws m, m*.
With this construction of sliding block and work frame it will be obvious that
work differing considerably in size can be secured in the frame and that the work
can be moved vertically by the screws f, fl and horizontally by the sliding
frame m through the medium of the hand wheel n¹.
p is the plate which I use in conjunction with my sliding block for supporting
work to be mitred, bevelled, moulded, fluted, or the like the said plate being fixed
upon a frame or support pl provided at its upper end with lugs p2, 22 adapted to be
suspended upon pins p3, p fitted to the upper ends of bars or rods 2, p which
slide in lateral guides f³ upon the sliding block f, set-screws f*, f being provided
for securing the sliding bars 2 in any desired position in the said guides so that
the plate p is supported on hinges which are adjustable vertically. To hold the
plate p at different inclinations to the face of the sliding block I provide slotted
bars hinged at one end to the plate p and held at their other ends by screws q¹
which pass through the slots so as to secure the bars q to the sliding block f. To
adjust the inclination of the plate p it will be obvious that it is only necessary to
loosen the screw q¹, slide the bars q thereon until the desired inclination is obtained
and to then tighten the screws q.
The lower portion 25 of the plate p is made to slide upon the frame p¹ and can
be adjusted by means of screws 26 which work in slots p in the said plate so as to
provide a slit r of varying breadth between the upper and lower portions p and p
of the plate, the said slit r being provided for the passage of a cutter or saw. The
plate is provided with suitable work guides or gauges s, t, u. The guides which
consists of a bar crossing the plate 2 can move up and down upon the said plate
by means of guide-bars s¹, s which move in grooves s2, s upon the frame p¹ and
can be secured in any desired position therein by means of set screws 3, 3. The
guide t is arranged to move upon the guide bar s. The guide bar u consists of a
curved plate which can be adjusted in position by means of screws and slots as
shewn in Figure 5 and is designed for use when it is desired to cut moulding such
as that shewn in Figures 5 and 8, that is to say, moulding having a wavy outline.
The method of employing my hinged plate for cutting mitres and the like is
shewn in Figure 1 the said plate p being fixed at a suitable inclination and the
cutter d projecting above its lower edge the plate po being removed. By removing
the frame m and fixing the plate p vertically I can cut mouldings or flutes.
In Figure 9 I have shewn the plate 2 and sliding block f arranged as a saw
bench. In this case the plate p is secured in a horizontal position and the strip p
of the plate is adjusted so as to leave a slit r of just sufficient width to take a
circular saw d. In this case the guide s is preferably reversed in position on the
plate p as shewn.
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. A machine for carving and moulding wood or the like comprising
a bed
provided with suitable uprights, a spindle carrying a cutter or a saw and adapted
to rotate in the uprights, a sliding block provided with means whereby it can be
adjusted in position upon the said bed and with a frame which can be moved
vertically upon it and is adapted to receive a work frame provided with means
whereby it can be moved horizontally in the frame on the sliding block,
substantially as described and illustrated.
2. The combination with a machine of the kind described in Claim 1 of a plate
adjustably hinged to the upper end of the sliding block and provided with means
whereby it can be fixed at any suitable inclination to the said block, the said plate
being provided with suitable gauges or guides and having its lower part made

page_text: adjustable and removable so that an adjustable slit can be provided through which
the cutter or saw can pass, substantially as described.
3. The combination and arrangement of parts forming the improved machine
for carving, cutting or moulding wood, hereinbefore described and illustrated in
the accompanying drawings.
