Improvements in Machines for Cutting Stone and other Substances.
I HUGH YOUNG of 188th Street and 4th Avenue in the City and State of New York,
United States of America, 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 object of my invention is to provide in one machine for the cutting of stone or
other substances into different forms having flat, polygonal, or curved surfaces; and a
machine embodying my invention is composed of certain distinct and specific parts
movable in certain distinct and specific lines by mechanism adapted to the production
of said movements of said parts; each of said distinct and specific parts, and the
mechanism for producing its distinct and specific movements, constituting a distinct
member of said machine, all of said distinct members, and the movements, thereof
being so arranged in relation to each other, that any one of said members may,
according to its fitness for the work required, be used as the primary or operative
member of the machine for the time being; during which primacy of said member, all
the other members of the machine, whether stationary or in continuous or intermittent
motion, become auxiliary for support, adjustment, or feed, the aim of this interchange-
ability of relation between the several members and movements thereof being to obtain
a maximum of geometric range and combinations from a minimum of parts and
movements.
I will proceed to describe a machine embodying my invention, and will afterwards
point out by claims the novelty of the invention.
In the machine selected to illustrate my invention, there are six distinct members,
cach of which has its own distinctive line of movement.
Member No. 1 has for its distinctive part a horizontal bed or table, and includes the
mechanism for moving said bed or table horizontally in the line of its own length.

page_text: Member No. 2 has for its distinctive part a rotary table, preferably mounted on the
horizontal table, and includes the mechanism for imparting to it its rotary motion.
Member No. 3 has for its distinctive part a cutter bar, and includes the mechanism
for imparting to it, movement in the line of its own length.
Member No. 4, has for its distinctive part vertical frames or gates, and includes the
mechanism for imparting to them vertical motion.
Member No. 5 has for its distinctive part a rotary autter-bar carrier mounted and
rotating on the vertically moving gates, and includes the mechanism for imparting a
rotary movement to said cutter-bur-carrier; and
Member No. 6 has for its distinctive part boxes radially mounted on the cutter-har-
carrier, in which the cutter-har slides in the line of its own length, and includes the
mechanism for imparting a radial movement to said boxes in their relation to the axis
of the cutter-lar-carrier.
In the accompanying drawings,
Fig. I represents a central vertical section of the machine.
Fig. 2 represents a horizontal section in the line 2x, Fig. 1.
Fig. 3 is a transverse vertical section in the line y y, Fig. 1, looking from the
leit.
Fig. 4 is a vertical section in the line 2, Fig. 1, looking from the right.
Figs. 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15, are diagrams illustrating the operations
performed by the mmchine.
Similar letters of reference designate corresponding parts in all the Figures.
A, B, C designate the stationary framing of the machine, represented as consisting
of upright posts A, an entablature B mounted thereon, and horizontal ways CC
1) designates a horizontal hed fitted to slide on the ways O, and having fitted to a
circular recess c, and pivot el, a circular rotary table E.
Between the posts A. on opposite sides of the ways C and bed D, are two upright
sliding frames or gates G, the faces of which are parallel with the ways CC, the sail
gates being fitted to the posts with gibs -Within each of these upright sliding
gates (i, is one of two rotary discs H, which combine to form what I will hereinafter
form the cutter-har-carrier.-Said cutter-har-carrier carries the cutter-bar I by means
of two sliding boxes J, which are fitted to slide radially in the discs H in parallel-sided
openings į provided in the said dises, the said boxes being movable towards and from
the centre of the discs.
The sliding bed 1, the rotary table E. the cutter bar I, the vertically sliding gates G,
the rotary cutter bar carrier HH, and the radially moving boxes JJ, are severally
provided with separate driving shafts for producing their respective movements.
D (Fig. 1) designates the driving shatt for the reciprocating bed 1 working in
bearings at d, and furnished with a toothed pinion gearing with a straight rack
on the bottom of the bed D. The said shaft is represented as furnished with tight
and loose pulleys d' d' d³, for open and crossed belts, to provide for turning the shaft
in both directions, and producing the horizontal movement of the bed Don the
slides C in either direction.-The said shaft D' is also represented as furnished with a
ratchet wheel, through which motion may bo communicated to it by a pawl deriving
motion in any suitable manner.
E designates the driving shaft for producing the rotary motion of the table E
within the bed 1, the said shaft working in a fixed bearing, as shown in Fig. 2, und
being provided with a bevel gear e gearing with a bevel gear e which turns loosely on
a fixed stud secured, as shown at ein Fig. 1, in the sliding bed D.-The said bevel
gear has secured to it another bevel gear e, which gears with a bevel gear e which
is secured to or integral with the bottom of the table . The bevel gear e being
required to move with the tablo E in the movemont of the latter with the bod, is
arranged to slide upon the shaft E', but compelled to rotate with it by being fitted to
said shaft with a square or spline, and it has a bearing e of its own, in which it rotates,
provided for it on the frame D. Said shaft E is represented as also furnished with
tight and loose pulleys e' e" and e³, for open and crossed belts, for driving it in either

page_text: direction, and also represented as furnished with a ratchet wheel e", through which it
may be turned by a pawl actuated in any suitable manner.
G¹ designates the driving shaft by which the upward and downward vertical move-
ment of the upright sliding gates G is produced, working in bearings * on the
entablature B of the framing. This shaft is furnished with three bevel gears g¹ g¹*
and g², forming part of a train of bevel gearing for turning the upright screws G2, by
which the upward and downward movement of the gates G is produced. These
screws, two for each gate G, are free to turn, but confined longitudinally in bearings
in the entablature B, and scrow into nuts G³ fixedly socured upon the said gatos G.
Each of the said screws is furnished with a bevel gear g³, these being all of equal size,
the gears g¹ and g¹*, which are of equal size, gearing directly with those ³ on two of
the screws (2, namely, one screw of each gate. The gears ³ of the two screws of
each gate are geared together by bevel gears, of equal size, on shafts go; one for
each gate, arranged at right angles to the shaft Gin bearings on tho entablature B.
By the system of gearing above described, the rotary motion of the shaft G¹
produces precisely corresponding movements of the gates G, whose positions
therefore always correspond. The shaft G¹ is represented as furnished with tight
and loose pulleys 97 98 and y, to receive open and crossed belts for driving it in
different directions. The said shaft is also reprosented as furnished with a ratchet
wheel through which it may be turned by a suitably actuated pawl.
H designates the driving shaft for producing the rotary movement of the cutter-
bar carrier H H within the gates G. This shaft is furnished at its ends with two
bevel gears h, of equal size, gearing with two bevel gears A', the hubs of which
are journalled into bearings. These bevel gears have fitted to them, with
squares or splines, upright shafts h³, which are journalled into bearings at on
the upper parts of the sliding gates G, and they are furnished at their lower ends
with bevel gears h, of equal size, gearing with large bevel gears hº, which aro
bolted to the outer faces of the cutter har carrier discs H H.
The shafts, receiving rotary motion through the bevel gears, are free to slide
lengthwise through the gears while they move up and down with the gates and the
contained cutter-har-carrier discs, so that no matter what the position of the gates
may be, the rotary cutter bar carrier is always in gear with its driving shaft.
The shaft H' is represented as furnished with tight and loose pulleys h', and h³,
for the reception of open and crossed belts for driving the shaft in either direction.
It is also represented as furnished with a ratchet wheel, through which it may
receive motion from a suitably actuated pawl.
In order to provide for locking the cutter-bar-carrier H H in any position to which
it may be turned, and so enable it to resist the pressure which in some sorts of work
may be brought on the cutter bar in a direction circumferential with, or tangential
to the said carrier, I have provided on the shaft H a locking wheel to be
engaged by a hooked dog hung on the entablature B, as shown in Figs. 1 and 3.
Tis the horizontal driving shaft for producing the longitudinal reciprocating
movement of the cutter bar I within and through the boxes J J hereinafter described.
This shaft is fitted to bearings in a vertically sliding cross-head F, which is fitted
by means of gibs f to two of the upright posts A of the main framing of the
machine. Within this cross-head, near the ends thereof, are provided nuts or female
screw threads, through which screw two upright screws F, the threads of which
correspond with the threads of the screws G, hereinabove described, for the purpose
of producing the upward and downward movement of the sliding gates G. These
screws are supported in bearings in the entablature B, in such manner as to allow
them to turn freely, but confine them lengthwise, and they are provided, at their
upper ends, with bevel gears f³, which are of the same size as the bevel gears g³
on the screws G². The bevel gear f³, on one of these screws, gears as shown in
Fig. 1, with the bevel gear on the right hand end of the shaft G before described,
and the two bevel gears on the two screws are geared together by two bevel
gears on a horizontal shaft 3, working in bearings on the entablature. The
bevel gears gl g¹ and g², being all of the same size, and the bevel gears and fl

page_text: being of the saine rize, and the bevel gears and being of the same size, the
screws I have always precisaly the same movements as the screws (, so that the
movement of the cross-head always corresponds exactly with that of the two sliding
gates G, and in fact, the two sliding gates and the cross hend F may be considered
as practically parts of one vertically sliding reciprocating carriage, within which the
cutter-bar carrier rotates in planes parallel with the reciprocating movements of the
said carriage, the said reciprocating and rotating movements being in planes perpen-
dicular to to the planes of the movements of the bed D and the table E.
One of the discs H of the rotary cutter-bar carrier, namely, the one shown at the
right of Figs. 1 and 2, has connected with it, by diagonal braces 20, a hollow
journal 21, which is concentric with the said dise, and which turns in a bearing at 22
in the crosshend F. These diagonal braces and this journal assist in establishing a
firmer base to that one of the dises I of the cutter-bar carrier to which is attached
the mechanism for producing the motion of the cutter bar in the line of its own
length.
The driving shaft 12, for producing the reciprocating longitudinal movement of the
cutter-bar, is fitted to hearings in the cross head F, and is furnished with a small spur
gear, which gears with a larger spur gear on a horizontal shaft, which works in
bearings within the centre of the hollow journal 21, as shown in Fig. 1, and in a
journal box provided on the adjacent dise H of the rotary cutter bar carrier. On
this sluit is provided an endless screw, which gears with two worm-gears upon
two parallel shafts, which are journulled in hearings firmly secured to the adjacent
dise 11. On these shafts are providel sleeve spur pinions, journalled upon the
sliding bar J, and which gear with toothed racks i̟ recessed in opposite sides of the
entter bar 1.
By means of the shaft I, spur gears, shaft, endless serow it, worm gears P,
shafts, pinions, and racks, a longitudinal movement is given to the cutter bar
in either direction, according to the direction of the revolution of the driving shaft l'.
In order that this movement of the entier bar may be produced at whatever distance
the said bar may be from the centre of its rotary carrier, the pinions are so fitted
within the boxes J, that they will move towards and from the centre with the said
boxes, and they are fitted to their shafts with splines or squares, so that they
may slide longitudinally on the said shafts, while compelled to turn therewith.
The shaft is furnished with fast and loose pulleys (", ", and, for the reception
of open and crossed belts for driving it in either direction. The said shaft is also
represented as furnished with a ratchet wheel ¿, through which it may receive motion
from a suitably actuated pawl.
Jin horizontal driving shaft for producing the movement of the boxes J and the
cutter bar 1, fitted thereinto, towards and from the centre of the cutter bar carrior.
The said shaft works, as shown in Fig. 1, în stationary bearings j*, and is furnished
at its ends with two bevel gears, which gear with hovel gears ja on the lower
ends of two upright shafts, on the upper ends of which are bevel gears,
which gear with bevel gears on two horizontal shafts, on which are
endless screws which gear with worm wheels provided on the screws
hereinhefore described, which work in nuts in the boxes J. The upright
shaft at the right hand end of the machine (see Fig. 1) has its lower journal
fitted to a fixed bearing 10, and its upper journal fitted to a bearing at jin
the cross bead F. The corresponding shatt, at the right hand and of the maching
(800 Fig. 1), passes through the shaft, which is bored to receive it. The said
shaft is journaled, near its outer end, in a bearing in the cross-head F, and is
journalled at its inner end in a bearing, secured concentrically to the adjacent
rotary disc H of the cutter-har-carrier. The upright shaft, and the horizontal
shaft, at tho left hand end of the unchine (see Figure 1), are journalled in bearings
in a bracket, which is secured to the adjacent sliding gate G, and the horizontal
shaft is journaliod, at its opposite ond, in a bearing secured concentrically to
the adjacent rotary disc II of the cutter-bar-carrier.
By the system of gearing hereinabove described, between the shaft J' and the

page_text: endless screws, the rotary motion of the said shaft is caused to produce the rotary
motion of the said screws, and thereby to move the boxes J and the cutter-bar I
towards or from the centre of the cutter-bar carrier H H, according to the direction
in which rotary motion is given to said shaft. In order that this rotary motion may
be produced without regard to the height of the vertically sliding carriage G H F,
the shafts, are male telescopic, so that they may be elongated and shortened as
the said sliding carriage ascends and descends, the upper and lower telescopic members
being fitted together with splines or squares. The shaft J¹ is represented as furnished
with pullies and j, to receive open and crossed belts for driving the said shaft
in either direction. The sail shaft is also represented as furnished with a ratchet
wheel, to be operated by a suitably actuated pawl.
It will be observed that each of the driving shafts D', E', G', H', I', and J', for
producing the movements of the different members of the machine, is furnished with
pullies for the reception of open and crossed belts for the purpose of producing the
rotation of the said shafis in one direction or the other, and so producing the
movement of the members of the machine which they actuate in one direction or
the other. It will be also observed that each of the said shafts is furnished with a
ratchet wheel, the latter wheel being for the purpose of providing for giving to the
said shaft a slow rotary motion. Each of the movements produced by the soveral
shafts D', E, G, H, I, J, is capable of producing either the operative movement
of the work, or of the cutter necessary for cutting, or the movement thereof
necessary for feeding and adjusting the work to the cutter, or the cutter to its work.
The cutter-bar I, which is not in itself a tool, is furnished with cutters K, which
may be of any suitable kind, the said cutters being held in adjustable stocks K' of
any suitable construction. The said stocks should be so applied to the cutter-bar I,
that they may be adjustable lengthwise thereof, and that the points or cutting edges
of the cutters may be presented upward, downward, latorally, or transversely, in any
direction suitable to the work, relatively to the said bar. The section of said bar, and
the interior of the stock, are represented as of rectangular section, but may be round,
or of any other section or shape desired.
It may be here mentioned that the cutter-bar does not itself rotate, but revolves
laterally around the axis of the rotary carrier in which it is mounted.
Having described the construction of the machine in detail, I will describe a few
of its operations in different kinds of work performed by it.
The stone to be operated upon is always supported by the bed D, either directly or
through the intervention of the rotary table E, suitable blocks I of wool or other
material being placed between the stone and the table or bed, if necessary, as shown
in Figures 5 to 15 of the drawings.
In all the examples of the operation of the machine, shown in Figures 5 to 10
inclusive, the cutter-bar is operatively movable in the direction of its own length, and
the work is done by the movement of the said bar and its cutter or cutters in that
direction. In the example illustrated in Figure 5, which represents the cutting of an
irregular polygonal prism by the longitudinal movement of the cutter-bar and cutter,
with the cutter set in a direction lateral to the said bar, the bed D and the block of stone
M supported thereon are stationary, and the feeding is performed by the movement
of the cutter-bar and cutter in a radial direction within the cutter-bar-carrier, as
indicated by an arrow in the Figure, the relative position of the tool to the work
having been previously established by the horizontal movement of the bed, the vertical
motion of the gates, and the rotary motion of the cutter-bar-carrier.-In the example
illustrated in Figure 6, which represents the cutting of a partly circular column by
the longitudinal movement of the cutter-bar and cutter, the bed D, and the work M
thereon are stationary, and the cutter, which is set on the inner side of the cutter bar
I, is fed to its work by the lateral revolving movement of the said cutter-bar and
cutter, produced by the rotating movement of the cutter-bar-carrier H H on its axis,
the proper radial position of the cutter-bar having been first established, and the stone
M having been also arranged concentric to the axis of the cutter-bar-carrier by the
horizontally moving table and vertically moving frame. In the example represented

page_text: in Figure 7, which represents the cutting of the inner are of a voussoir, the cutter is
set on the outer side of the cutter-har, the bed D and the stone M are stationary, and
the cutter-bar, besides having a longitudinal operative movement by which the cutting
is produced has a lateral revolving feeding movement given to it by the circular
motion of the cutter-bar-carrier HH, the relative position of the tool to the work
having heen previously established by the radial movement of the bar,—the vertical
movement of the gates, and the horizontal movement of the table.
In the example illustrated in Figure 8, which represents a simple horizontal planing
operation by the lengthwise operative movement of the bar, the cutter is set on the
inner side of the bar, and the block of stone M is fed to the cutter by the movement
of the led on the ways (, the cutter-har-arrier H being stationary, the relative
position of the tool to the work having been previously established by the vertical
movement of the gates, the rotary movement of the cutter-bar-carrier and the radial
movement of the bar---In the example shewn in Figure 9, which illustrates the
planing of a vertical flat surface, the planing is also done by the longitudinal
operative movement of the cutter-bar. The he and the stone M are stationary,
and so is the cutter-har-carrier H. and the feeding is produced by the downward
vertically radial movement of the cutter-lar in the carrier H, the relative position of
the tool to the work having been previously established by the horizontal movement
of the le, the vertical movement of the gates, and the rotary movement of the
cutter-bar-carrier. In the example shewn in Figure 10, which also illustrates the
planing of a vertical that surfa e, by the same operative movement of the cutter-bar
and cutter, the bed D and the stone M are stationary, the cutter is set on the inner
side of the cutter-har L. the cunter-har-carrier 11 is stationary within the upright
sliding gates G, and the feeding of the entter to the work is produced by the inove-
ment of the gates (1, the relative position of the tool to the work having been pre-
viously established by the horizontal movement of the table, the rotary movement of
the cutter-lur-carrier, and the radial motion of the lar.
In the examples shewn in Figures 11, 12, 13, 11, 15. the longitudinal movement of
the outer bar is not the operative or primary movement by which the entting is
effected, but becomes subordinate, for the purposes of adjustment or feed-In Figure
11, which illustrates the transverse cutting of one of the sides of an irregular prism,
the bed 1) and the stone M are stationary, the cutter is set on one side of the bar; the
operative movement for cutting is the upward radial movement of the cutter har I, and
the feeding of the cutter to the work is produced by the longitudinal movement of the
entter-bar, while the carrier His stationary, the relative position o: the tool to the work
having been previously established by the horizontal movement of the bar, the vertical
movement of the gates, and the rotary movement of the cutier-bar-carrier.-In the
example shown in Figure 12 which illustrates the transverse cutting of a partly circular
body, the enter is set on the inner side of the cutter-bar: the operative movement for cutt-
ing is the laterally revolving movement of the entter bar, produced by the rotary move-
ment of the cutter-bar-carrier H, and the feeding of the cutter to the work is pro-
duced by the longitu linal movement of the cutter-bar, the bed 1) and the stone M
being stationary, the relative position of the tool to the work having been previously
established by the horizontal movement of the table, the vertical movement of the
gate, and the radial movement of the cutter-bar. In the example shewn in Figure 13,
which illustrates the cutting of the inner are of a moulded voussoir, the cutter is set
on the outer side of the bar, the operative movement for cutting is the laterally revolv-
ing movement of the cutter-bar produced by the rotary movement of the carrier II,
and the feeding of the cutter to the stone is produced by the longitudinal movement
of the bar, the bed and the stone M. being in this case stationary, the relative posi-
Lion of the tool to the work having been previously established by the same means
as in No. 12. In the example shewn in Figure 14, which represents the cutting of
the plinth of a circular column, the operative movement for cutting is the rotary
movement of the table E, and the cutter, which is set laterally to the bar, is fed to
the stone by the radial movement of the bar within the carrier H, the bed and the

page_text: carrier being stationary, the relative position of the tool to the work having been
previously established by the lengthwise movement of the bar, the horizontal move-
inent of the table, the rotary movement of the cutter-bar-carrier, and the vertical
movement of the gates. In the example shewn in Figure 15, which illustrates the
horizontal planing of the upper side of a slab, the operative movement for the cutting
is the horizontal movement of the bed D on the ways C, and the feeding of the
cutter to the work is produced by the longitudinal movement of the cutter-bar, while
the carrier His stationary, and in this case the cutter is set on the outer side of the
bar, the relative position of the tool to the work having been previously established
by the vertical movements of the gates, the rotary movement of the cutter-bar-carrier,
and the radial movement of the cutter-bar.
The adjustment of the depth of cut may be produced by moving the stone towards
the cutter, or the cutter towards the stone, the movement being effected by slowly
turning such one of the several driving shafts as will produce the movement
desired.
