hereby declare the nature of this invention to be as follows:-
The invention relates to an improvement in carving machines.
The object of the invention is to produce a machine, the several parts, of which
shall be capable of all necessary adjustments, by which any desired pattern may
be placed upon or pressed into material such as wood, papier-maché, etcetera.
The accompanying drawings illustrate the improved machine.

., .
In the drawings, 8 indicates a suitable base upon which is securel a pair of
uprights 9 and 10, the upper ends of which are connected by the cross-piece 11.
Cross-piece 11 is, at one point, formed into a head 12 through which is formed a
vertical opening 13. Mounted in opening 13 is the hub 14 of a bearing-ring 15
which is provided with an external flange 16 which rests upon the upper face
of the head 12. Opening 13 is slightly longer than the diameter of the hub 14
and said hub is radially movable within said opening, being retained in any one
of its adjusted positions by means of suitable bolts 16. Hub, 14 is, provided, at
its lower end, with an internal flange 17 upon which rests a series of rollers 18
which form an annulus, within which may be inserted the vertical die-shaft 19.
In order to retain the rollers in position any desired means may be employed.
the drawings the flange 17 is shown provided with an upturned. lip, 20 and
the upper ends of said rollers are held by a retaining annulus, 21. The die
shaft 19 may be inserted through the annular series of rollers 8 and is held in
vertical position by means of a flange 22 carried by said shaft, and resting upon
the upper end of the bearing-ring 15. The lower end of the die-shaft 18.
into a ring 23 which is supported between the two lips 24 of the carrier, 25 which
carrier is mounted upon the base 8 immediately beneath the head 12 and is
movable upon said base, in the same directions as the bearing-ring 15, by means of
the adjusting bolts 26: The die-shaft is provided, at its lower end, with a suitable
passes

key-way which receives a key 27 carried by the ring 23. Ring 23 engages a pair
of rollers 28 mounted in the carrier 25 and rotating about pins 29, a series of
rollers 30 being introduced between said pins and rollers. The rollers 28 both
engage the ring 23 upon that side which is opposite the feed-table, to be
described, for the purpose of sustaining the thrust caused by the insertion of the
material to be worked upon between the feed-table and the die. Mounted upon
the base 8 and movable radially toward and from the die-shaft is a feed-table 31
which is substantially vertical and parallel with the die-shaft. Table 31 is
provided on its rear with a housing 32 within which is mounted a feed-roll 33
which is rotatable about a vertical shaft 34. The roll 33 projects slightly
through the table 31, as clearly shown in Figure 1. Shaft 34 passes, at its lower
end, through a bearing 35 which is secured to and forms a part thereof, and
secured to the lower end of said shaft is a worm-gear 36 which meshes with a
worm 37 keyed to but longitudinally movable upon a main drive-shaft 38.
Mounted within bearing 35 is a pair of bushings 39 one of which may be forced
toward the shaft by means of a pair of set-screws 40. Worm 37 is surrounded
by a housing 41 which is either integral with or secured to the bearing 35 and moves
with said bearing when the feed-table is moved back or forward upon the base 8.
Mounted in housing 41, one at each side of the worm and surrounding the
shaft 38 are two bushings 42, each of which is threaded upon its outside so that
may be adjusted within the housing toward or from the middle thereof. The
inner ends of the bushings 42 engage collars 43 which in turn engage the ends
of the worm. By this means the worm may be adjusted so as to lie at any
desired point within the housing 41 and the thrust thereof is taken, through the
bushings, by the said housing.
it
Table 31, together with the parts attached thereto, is mounted in suitable
guide-ways 44 on the base and the cross-piece 11 and may be adjusted toward or
from the die-shaft by means of the screw 45 the inner end of which enters a
suitable nut 46 carried by the housing 32, and the opposite end of which engages
the upright 10. For the purpose of easily turning the screw 45, and thus
adjusting the table 31, a wheel 47 is secured to said screw, the said wheel being
provided, on its periphery, with a series of notches 48. Pivoted upon the screw 45
is a lever 49 upon which is mounted a spring-catch 50 adapted to enter any one
of the notches 48.
In order to properly present the material to be worked upon to the die 51, upon
the face of the table 31, is mounted a pair of shelves 52, each of which is verti-
cally adjustable thereon by means of a shaft 53 extending across or along said
shelf and turning in suitable bearings carried thereby. Secured to each end of
each shaft 53 is a skew gear 54 which engages with a threaded rod 55, one of
which is mounted at each end of the feed-table 31. The ends of shafts 53 are
suitably squared to receive a suitable handle or crank 56 by means of which the
said shafts may be turned and the positions of the shelves be changed upon the
feed-table. By this means the shelves, between which the material is guided
are always maintained in a horizontal position and square with the die.
In order to easily remove the die-shaft, it is provided, at its upper end, with
an eye 57 adapted to receive a hook 58 secured to the end of a cable 59 which
cable is passed up over a pair of pulleys 60 carried at the upper end of a swing-
ing crane 61 and secured to a winding-drum 62 mounted upon the upright 9.
The die 51 is secured to the die-shaft 38 by any suitable means, as for instance
a pair of threaded collars 63 and 64 which are threaded upon the shaft and
between which the die may be clamped.
In the class of work performed by this machine it has been found advisable
to have the die maintained at a comparatively high temperature and for this
purpose the die-shaft is made hollow and mounted beneath the lower end thereof
is any suitable source of heat. In the present case this means consists of a gas-
burner which is secured to the upper end of a pipe 65.
In operation, after the die-shaft and die have been placed in position, table 31

page_text: is thrown forward or back until the distance between the feed-roll and die is
somewhat less than the thickness of the material to be operated upon, the dis-
tance depending upon the depth to which the raised portions of the die are to be
sunk into the material. Shelves 52 are then adjusted to suit the width of said
material and the feed-roll started to rotating. The material is then presented
to the feed-roll and by it drawn through between the roll and die, the raised por-
tions of the die being thus sunk into the material and the die and die-shaft
turning about a vertical axis. It will be noticed that the die-shaft is so sup-
ported, top and bottom, as to fully meet the thrust occasioned by the passage of
the material operated upon and that any wear may be easily and quickly taken
up by the re-adjustment of the bearings.

'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, 118, New Street, Birmingham, in the County of
Warwick, and 322, 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 to an improvement in carving or impressing machines.
The object of the invention is to produce a machine, the several parts of which
shall be capable of all necessary adjustments, by which any desired pattern may
be placed upon or pressed into material such as wood, papier-maché, etcetera.
The drawings accompanying the Provisional Specification illustrate the im-
proved machine.
Figure 1 is a perspective view thereof;
Figure 2 is a sectional plan of the lower bearing for the die-shaft;
Figure 3 is a front elevation thereof;
Figure 4 is a sectional plan of the upper bearing for the die-shaft;
Figure 5 is a vertical section of said bearing;
Figure 6 is a vertical section of the lower bearing for the feed-roll;
Figure 7 is a detail of the support for the driving-worm.
In the drawings, 8 indicates a suitable base upon which is secured a pair of
uprights 9 and 10, the upper ends of which are connected by the cross-piece 11.
Cross-piece 11 is, at one point, formed into a head 12 through which is formed a
vertical opening 13. Mounted in opening 13 is the hub 14 of a bearing-ring 15
which is provided with an external, flange 16 which rests upon the upper face.
of the head 12. Opening 13 is slightly longer than the diameter of the hub 14
and said hub is radially movable within said opening, being retained in any one
of its adjusted positions by means of suitable bolts 16. Hub 14 is provided, at
its lower end, with an internal flange 17 upon which rests a series of rollers 18

page_text: which form an annulus within which may be inserted the vertical die-shaft 19.
In order to retain the rollers.in position any desired means may be employed.
In the drawings the flange 17. is shown provided with 'an upturned lip 20 and
-the upper ends of said rollers are held by a retaining annulus 21. The die
sliaft 19 may be inserted through the annular series of rollers 18 and is held in
vertical position by means of a flange 22 carried by said shaft and resting upon
the upper end of the bearing-ring 15. The lower end of the 'die-shaft 19 passes
into a ring 23 which is supported between the two lips 24 of the carrier 25 which
..carrier is mounted upon the base 8' immediately beneath the head 12 and is
-movable upon said base, in the same directions as the bearing-ring 15, by means of
the adjusting bolts 26. The dic-shaft is provided, at its lower end, with a suitable
key-way which receives a key 27 carried by the ring 23. Ring 23 engages a pair
of rollers 28 mounted in the carrier 25 and rotating about pins 29, a series of
rollers 30 being introduced between said pins and rollers. The rollers 28 both
engage the ring 23 upon that side which is opposite the feed-table, to be
described, for the purpose of sustaining the thrust caused by the insertion of the
material to be worked upon between the feed-table and the die. Mounted upon
the base 8 and movable radially toward and from the die-shaft is a feed-table 31
which is substantially vertical and parallel with the die shaft. Table 31 is
provided on its rear with a housing 32 within which is mounted a feed-roll 33
which is rotatable about a vertical shaft 34. The roll 33 projects slightly
through the table 31, as clearly shown in Figure 1. Shaft 34 passes, at its lower
end, through a bearing 35 which is secured to and forms a part thereof, and
secured to the lower end of said shaft is a worm-gear 36 which meshes with a
worm 37 keyed to but longitudinally movable upon a main drive-shaft 38.
Mounted within bearing 35 is a pair of bushings 39 one of which may be forced
toward the shaft by means of a pair of set-screws 40. Worm 37 is surrounded.
by a housing 41 which is either integral with or secured to the bearing 35 and moves.
with said bearing when the feed-table is moved back or forward upon the base 8.
Mounted in housing 41, one at each side of the worm and surrounding the
shaft 38 are two bushings 42, each of which is threaded upon its outside so that
it may be adjusted within the housing toward or from the middle thereof. The
inner ends of the bushings 42 engage collars 43 which in turn-engage the ends
of the worm. By this means the worm may be adjusted so as to lie at any
desired point within the housing 41 and the thrust thereof is taken, through the
bushings, by the said housing.
Table 31, together with the parts attached thereto, is mounted in suitable
guide-ways 44 on the base and the cross-piece 11 and may be adjusted toward or
from the die-shaft by means of the screw 45 the inner end of which enters a
suitable nut 46 carried by the housing 32, and the opposite end of which engages
the upright 10. For the purpose of easily turning the screw 45, and thus
adjusting the table 31, a wheel 47 is secured to said screw, the said wheel being
provided, on its periphery, with a series of notches 48. Pivoted upon the screw 45
is a lever 49 upon which is mounted a spring-catch 50 adapted to enter any one
of the notches 48.
In order to properly present the material to be worked upon to the die 51, upon
the face of the table 31, is mounted a pair of shelves 52, each of which is verti-
cally adjustable thereon by means of a shaft 53 extending across or along said
shelf and turning in suitable bearings carried thereby. Secured, to each end of
each shaft 53 is a skew gear 54 which engages with a threaded rod 55, one of
which is mounted at each end, of the feed-table 31. The ends of shaft 53 aré
suitably squared to receive a suitable handle or crank 56 by means of which the
said shafts may be turned and the positions of the shelves be changed upon the
feed-table. By this means the shelves, between which the material is guided
are always maintained in a horizontal position and square with the die.
In order to easily remove the die-shaft, it is provided, at its upper end, with
an ere 57 adapted to receive a hook 58 secured to the end of a cable 59 which

page_text: cable is passed up over a pair of pulleys 60 carried at the upper end of a swing-
ing crane 61 and secured to a winding-drum 62 mounted upon the upright 9.
The die 51 is secured to the die-shaft 19 by any suitable means, as for instance
a pair of threaded collars 63 and 64 which are threaded upon the shaft and
between which the die may be clamped.
In the class of work performed by this machine-it has been found advisable
to have the die maintained at a comparatively high temperature and for this
purpose the die-shaft is made hollow and mounted beneath the lower end thereof
is any suitable source of heat. In the present case this means consists of a gas-
burner which is secured to the upper end of a pipe 65.
In operation, after the die-shaft and die have been placed in position, table 31
is thrown forward or back until the distance between the feed-roll and die is
somewhat less than the thickness of the material to be operated upon, the dis-
tance depending upon the depth to which the raised portions of the die are to be
sunk into the material. Shelves 52 are then adjusted to suit the width of said
material and the feed-roll started to rotating. The material is then presented
to the feed-roll and by it drawn through between the roll and die, the raised por-
tions of the die being thus sunk into the material and the die and die-shaft
turning about a vertical axis. It will be noticed that the die-shaft is so sup-
ported, top and bottom, as to fully meet the thrust occasioned by the passage of
the material operated upon and that any wear may be easily and quickly taken
up by the re-adjustment of the bearings.
Having now particularly described and ascertained the nature of the said
invention 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. An impressing or carving machine, characterised by an impressing die
mounted on a die shaft and passively rotated by the passage of the material
operated upon, a table so arranged in proximity to and parallel with the said
impressing die that it can be moved forward or from the die to adjust itself to
the thickness of the material, and shelves or guides on the face of the table
adjustable to suit the width of the material and yet be square with the die, in
combination with a feed roll the periphery of which slightly projects through
and beyond the table, whereby wood, papier maché, etcetera, may be drawn
through the feed table and die and be maintained truly square with the die and
table in its transit between them, substantially as described.
2. In an impressing or carving machine of the kind described in which there
is a rotary die mounted on a die shaft, arranging the bearings above and below
the die in such a manner as to sustain the thrust caused by the insertion of the
material to be worked upon between the feed table and the die, while enabling
any wear to be easily and quickly taken up.
3. In an impressing and carving machine of the kind described, a feed table
mounted in suitable guideways so that it can be adjusted towards or from the
die shaft, a housing provided at the rear of the table within which is mounted a
rotary feed roll projecting slightly through the table surface, in combination
with a screw, one end of which enters a suitable nut carried by the housing, and
the other end provided with means for turning the screw, whereby the feed table
can be adjusted towards or from the die shaft.
4. In an impressing or carving machine in which there is a rotary die mounted
on a die shaft, providing at the upper end of said die shaft, a swinging crane
mounted on the frame of the machine, a cable passing over pulleys carried at
the upper end of the cranc, said cable being secured at one end to a winding drum,
and at the other end capable of being coupled to or uncoupled from the end of
the die shaft, whereby the die shaft can be easily removed when required.
5. In an impressing or carving machine, in which there is a feed table having
a feed roll slightly projecting through the surface thereof, and in which also a
worm wheel is mounted on the shaft which carries the said feed roll meshing into

page_text: a worm keyed to, but longitudinally movable upon, a main drive shaft; the
arrangement for moving this worm longitudinally upon the shaft, which con-
sists in surrounding the worm by a housing or frame, and mounting in this
housing, on the worm shaft, the bushes 42, each of which is threaded on the out-
side so that they can be adjusted within the housing towards or from the middle
thereof, the inner ends of these bushes abutting against the end of the worm or
against collars at the ends thereof, whereby the worm may be adjusted to lie at
any desired point within the housing to correspond with the position of the shaft
carrying the worm wheel, substantially as described.
:
6. A die shaft mounted on or in connection with roller bearings above and
below the die so as to sustain the thrusts caused by the insertion of the material
to he worked upon between the feed table and the die and means for adjusting
said bearings to take up wear.
7. An impressing or carving machine characterized by a hollow vertical die
shaft upon which a die may be secured, a feed-roll located parallel with and in
proximity to the die-shaft and having means by which it may be rotated, and a
heating means located beneath the hollow die-shaft.
