PROVISIONAL SPECIFICATION.
An Improved Machine for Cutting, Grinding, and Polishing Glass
and such like Substances.
CHARLES MARLOW 142 Park Lane Aston near Birmingham in the County
of Warwick Metal Plate Worker and Machinist do hereby declare the nature of
this invention to be as follows :-
:-
One part of the improvement relates to the method of holding the glass &c.
and the means used for removeing it from one process to another without disturbing
it. Another to the collection and redistribution of the sand, water, or other
substance used as an abradent. And to the general distribution of the parts,
which are so arranged as to reduce the space occupied. And to protect all
moveing parts from water, sand or other substances. And to economise labour and
time.
With this machine I propose to opperate upon any form of surface, wether flat
raised, or depresed, by means of rotating cutters or rubbers guided in some such
manner as those in use in wood working machines, with such modifications as the
nature of the work demands, and as set forth hereafter. Any of the usual motive
powers may be used to drive it.
This machine is rendered so nearly automatic that one attendant may attend
to two or more machines, according to the size of the work thereon. And the
movements of the machine can by guide rods, ropes, leavers or other suitable
means be brought so as to be easy of control from one seat or position however
large the machine.
The machine consists of a table of cast iron or brass, so constructed as to
move freely but truly in a rectileanel manner, upon guides by means of suspencion
brackets, or the guides may be placed in any other conveinant position, were
provision can be made for protecting it from damage by sand, water &c.
Its movement may be brought about by means of a toothed rack and pinion,
leaver or otherwise. Upon the corners of this table should be firmly fixed four
pedistals of conveinant height, and adjustable, for the purpose of supporting a
cast iron grid or lattice equal in area and paralell to the said table. In small
machines it may be required to support this grid by some other means, than the
four pedistals mentioned.
This grid is used under certain circumstances for holding the pattern or form,
and when so used, reduces the table space required by about seventy per cent.
compaired with what would be required in any machine, were the pattern is laid by
the side of the work, as is done in most coppying machines. This new position
of the pattern or form also adds much to its durrabillity. Between this grid and
table at any suitable height and near its centre of length, is fixed a frame or bridge
carrying a compound slide, whose movement is horisontal and face vertical it has
also other minor movements which movements can be brought about and controled
by any suitable means. Upon this slide, so as freely to rotate either with the sun
or against it, to rise or fall, or be set at any height or angle, is a spindle, carrying
near its lower end an attachment, consisting of toothed or friction wheels so con-
structed as to cause cutters or grinders to rotate horisontally, vertically, or at an
angle, and a ready means of chainging such cutter &c. by means of a set screw
slip joint, or wedge. Firmly fixed to this slide in a vertical position, so as to be
set, erect or pendant, is a finger, tracer, or pointer, haveing at its extreem end_an
exactly simula set screw, slip joint, or wedge as the one described above, so that
smooth copys of the cutters or other tools may be readly attached there to or as
readly removed. This finger although riged in all other directions may receive a

page_text: certain, regulateable and elastic vertical movement, both rise and fall, either at will
of operator or by comeing in contact with the pattern or template which movement,
and all others imparted to it, it transmits to the cutter spindle, in some cases direct
and in others through the medium of a, leaver. Under the table, (which is
perforated with holes as required,) is placed a trough so as to catch all the water
and sand that falls through, and whose sides are at such an inclination as will not
allow the sand to repose, but, conduct it against a worm conveior, situate at its
bottom, and which in its turn causes it to enter an elevator of the usual type con-
sisting of an endless belt or chain carrying buckets, which fill at the bottom and
empty themselves upon reaching the top. The sand &c. is thus returned in to an
hopper from which it flows back to the work.
To hold some of the glass goods, it is not conveinant to use cramps, vices, or
cement, although for others it may be so.
To enable my machines to grip flat plates, so as to leave their edges free, and
for many other forms of work I have invented a frame or stool, haveing a suitable
surface, perforated and covered with a coating of india rubber haveing coresponding
perforations, and under each or any of these holes is fixed strong and air tight, a
strong concave disc of india rubber. Now if glass, oiled or moistned be pressed
over the top of the sells thus made, so as to close it, if by some such means as a
leaver or screw, the concavety of the disc be increased, a portion of the atmospheric
pressure will be removed from under the glass, which will be found to rest firmly
in its place upon the stool. Several of these stools, made interchangeable, being
provided, the work may without being disturbed from its seat, he moved bodily
and safetly to another machine or process, or it may become the raw material of
another simula machine.
To illustrate the working of the machine upon one kind of work, say a shield
shape, or serool of plate that requires beavelling or molding round its edges which
consist of straight and curved lines, angles of all kinds, except very acute internal
ones (the limit here is the dia. of the cutter). First fill the hopper with sand and
water, keeping the tap shut, (or the first supply could be placed under the table).
Next fix the outline model or template in a central position, upon the under side of
the grid, over the table, or if a small one it may be fixed upon the table at one side
thereof. Then fix the rough glass to a suitable vacum stool, and the stool to the
table, by means of four poppets placed in holes in the table, see that the pointer
and the cutter, touch coresponding parts of the pattern in the one case and of the
work in the other. Then adjust the height of the cutting spindle, start the machine
allow the water and sand to flow freely over the cutter on to the glass. By moveing
the table and slide in a proper manner, the conformation of the model can be
followed, and, werever the glass offers any resistance, to such travel, it will be
ground away until the model and the glass are equal in form, and their size bears
the required relation, as it may be larger or smaller at will, or by haveing the
pointer iregular the shape may be departed from in almost endless vairiations. By
loosening two of the poppet screws the stool may be removed and another being
placed in its place the work may proceed without any further adjustment, until the
whole be finished. As long as the machine works the water will circulate, and
prevent undue heating of the work.
The movement of the table can in some work be best done, automatically by
cords, leavers or otherwise. Again in others the pattern may be upon the table.
By mounting a number of spindles upon the bridge or slide, several equal articles
can be produced at one and the same time.
For working upon a variety of surfaces but slight differances of adjustment, are
required, in the play vertically of the cutters, their shape, their movements
horisantilly, caused in some cases by altering the model the finger, the rate of
travel or all of these, the whole of which are under complete control

described.

An Improved Machine for Cutting, Grinding, and Polishing Glass,
and such like substances.
I, CHARLES MARLOW, of 142, Park Lane, Aston, near Birmingham, in the
County of Warwick, Metal Plate Worker and Machinist, 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 :-
My invention relates to an improved machine for cutting, grinding and
polishing glass and other similar articles such as drinking glasses, decanters, liquor
and perfume bottles and the like. The characteristic features of novelty of my
invention, are the compactness of the machine which occupies a very small
amount of place, the mechanism for holding and moving the glass articles
under treatment and the mechanism for feeding and redistributing the sand
or other abradant, used in such a manner that the same may after a pre-
liminary straining operation serve recurrantly for the same purpose. By
means of my improved machine I am enabled to operate upon surfaces of
any form or shape in imitation of the model pattern template or finished article,
which has to be reproduced in glass, and I can moreover modify such imitation in
various ways so as to alter if desired and according to taste, some of the features of
such pattern or template, while several articles may be operated upon simul-
taneously, only one attendant being required for one and in some cases for two
machines.
In carrying my invention into practice 1 provide a frame carrying a table or
truck capable of moving to and fro upon wheels carried by axes, which are fixed to
the upturned edge or flange of the said table. The frame is formed moreover with
a slide arranged above the table and upon which slides an overhead carrier con-
sisting of various parts which may be connected together and disconnected one from
the other according to the requirements of the work in progress. This carrier
which is operated by suitable levers consists of two side frames in which are centrally
fitted by means of sleeves, two spindles formed each of two detachable parts joined
together by a cotter. The lower end of each spindle carries a rotary cutter or mills
operating against a bottle or glass which is held upon a vacuum stool arranged
upon the table aforesaid. The carrier consists further of a central pendant carrying
also by means of a suitable sleeve the central spindle of the machine upon which is
mounted a tracer wheel working upon the model template or finished article which
it is desired to reproduce.
The sand and water are conveyed to the cutters through an upper hopper, the
discharge opening of which is controlled by a valve and leads to another and larger
hopper furnished with two legs terminated by india rubber pipes. The lower ends
of these pipes-pass through suitable perforations formed in two discs mounted on
the cutter spindles.
Below the table aforesaid is arranged an apron into which the sand and water
drops from the cutters and is led thence to a conveyor which raises it to the top of
the machine whereat it is discharged through a shoot furnished with a sieve or
strainer into the upper hopper aforesaid. Suitable gearing or driving mechanism is
provided to set the spindles and the conveyor pullies in motion.
In the accompanying eight sheets of drawings
Figs. 1, 2, and 3 are respectively a front elevation, an end elevation and a plan of

page_text: my improved glass cutting, grinding and polishing machine arranged to simul-
taneously operate upon two glass articles.
Figs. 4 to 13 are enlarged views illustrating various modes of holding and
adjusting the different glass articles under treatment.
Figs. 14 and 15 shew the position of a decanter, liquor, or perfume bottle when
its under surface is operated upon.
Figs. 16 17 and 18, are enlarged views of three cutter holders illustrating the
mode of adjusting them for the various kind of work required.
Fig. 19 shows my improved machine modified for the purpose of grinding or
polishing the surfaces of decanters or liquor bottles.
Fig. 20 shows another modification of the same machine applicable for cutting,
grinding and polishing the surfaces or edges of plate glass or other articles.
Like letters of reference indicate corresponding parts throughout the several
sheets of drawings as shewn in Fig. 1 2, and 3. My improved machine consists of
a frame work formed with an upper slide, upon which moves the carrier
furnished on both sides with a frame comprising each two movable parts c and d
the former of which slides horizontally upon the piece 6 while the latter slides
vertically upon guides or recesses formed in the said part c. The vertically sliding
part d carries the bearings upon which rotates the sleeve or holder fand with it
the rotary spindle e. The roller q journalled in the ends of the frame a communi-
cates to the holder by means of the belts p the motion imparted thereto by the conc
pulley which is mounted on the journal a as clearly shown in Fig. 1, this journal
carrying moreover the pulleys ry Band 4. The vertically moving part d is furnished
with a lower extension upon which moves a detachable sliding block i fixed in
position thereon by the screws, as illustrated more particularly in Fig. 16 which
shews on an enlarged scale a front and end elevation and a plan of the cutter
mechanism, e is the spindle rotating within the bearings 9 g and the lower and
hollow part of which receives the reduced end of another spindle e², secured therein
by means of a cotter 2. Upon the lower end of the spindle e² is mounted a cutter k
while a similar cutter is mounted on the spindle carried by the frame F on the other
side. B is a table or truck mounted upon four wheels C moving on the rails D laid
on each side of the machine as shewn; this table is furnished in the centre of its
under surface with a rack E actuated by a pinion which is mounted at the end
of a horizontal shaft G carried at its extremities by the frame a and the upright E°
respectively and rotated by the hand wheel Gº.
The vacuum stools H H Figs. 1 and are arranged upon the table B being held
thereon by the screws R working through the blocks or guides R°; they
support the two bottles or decanters I, which are being ground or cut and rest
upon an india rubber sheet J of suitable thickness. Below each stool is fixed an
air tight concave india-rubber disc L by means of which a vacuum is produced and
the bottle is held tightly in position. This disc L is furnished at its lower end
with a ring and is fixed to the table B by means of screws passing through the
horizontal limb of a quadrant, the circular part of which is secured to the disc L,
by means of a screw pin N fixed to a hook which is attached to the ring §, of
the said disc, a wing nut " screwed upon the end of the pin N as shewn in Fig. 1
permitting of the disc L being drawn or elongated for the purpose hereinafter
set forth. The table B is furnished centrally with a step S in which is mounted
an upright supporting a circular platform or dise » upon which is arranged a
vacuum stool 3 constructed and fixed in the same manner as the stool H above
described, this stool carrying the model or finished article W which it is desired
to reproduce. Upon the central part of the carrier 1, slides an adjustable block m,
supporting the sleeve or bearing n, in which turns the vertical spindle o carrying
the tracing wheel 2. S is a hand lever by means of which the vertically sliding
parts c and d are moved horizontally or vertically according as required; this lever
being connected to the latter parts by the ring T and fulcrumed upon the universal
joint U fixed to the upright W.

Beneath the table 13 is arranged an apron 16 of sheet iron or other suitable

page_text: metal which carries the sand and water dropping from the cutters kand
to the trough 16, in which revolves upon a shaft m, carried at its extremities by the
supports S S the feeding screw 15 conveying the sand and water from the
apron 16 to the buckets of the elevator 2.
The latter is an ordinary bucket elevator having for its object to continuously
redistribute in a strained state to the cutters k and k¹, the sand and water which
have previously dropped therefrom. This clevator is actuated by the drums 3'
and 3 mounted upon axes carried by the frame 1 and driven by the roller shaft a,
by means of a belt passing over the pulley 4 and over the pulley 5 mounted on
the shaft of the drum 3 which imparts a motion to the drum 3" through the
elevator 2.
The shaft of this drum 3" is supported by an upright 3d and carries at its outer
end a pulley 6 which imparts by means of a belt, a rotary motion to the pulley 7
mounted upon the shaft m, of the feeding screw, and thus rotates the latter. The
buckets discharge their contents as they reach the top of the elevator 2 into an
inclined shoot 8 furnished with a sieve or strainer 9 which retains the lumps of
sand and glass and allows the fine sand and water to run into a hopper 10, while
the said lumps fall into a receptacle 11. The sand and water falls from the
hopper 10, the discharge opening of which is regulated by the valve or damper 10
into the large hopper 12 furnished with two tubular legs 13 connected at their
lower ends to the pipes 14 which pass through suitable perforations formed in the
quadrants and the free ends of which feed the sand and water to the cutters k k¹.
My improved machine operates as follows:-All the parts being in the position
illustrated in Figs. 1, 2, and 3 the vacuum stools H H and H³ are first adjusted on
the table B with the aid of the screws R and the bottles or decanters II and the
pattern or finished article wo are placed in position on their respective stools, care
being taken to previously smear the bottom of the said bottles with oil or water.
The nut on the screw pin N is now adjusted whereby the disc L is drawn outwardly
and caused to expand thus forming a pouch in which a vacuum is created in con-
sequence of the removal of the atmospheric pressure from under the glass bottles
which are now firmly held in position by suction. When a bottle requires to be
removed the nut of the screw pin N is released allowing the pouch to return to
its normal disc like form and thus release the bottle. The table B is now moved
forward by turning the hand wheel Go, to the position shown in dotted lines in
Figs. 2 and 3. The tracer wheel 2 and the cutters and are correspondingly
placed in position against the surface of their respective articles which is to be
traced or operated upon and motion is imparted to the machine causing the belts p
to rotate the cutters and while the tracer wheel is free to move upon its
spindle o. It will be readily understood that as pressure is applied by means of
the lever S the cutters k and k' will form on their respective bottles a cut
corresponding to that passed over on the pattern by the tracer wheel while by
lowering at suitable intervals the said cutters k k¹ and the tracer wheel 2 a series
of superposed cuts will be formed on the surface operated upon which in the
When these cuts
example shown in Fig. 1, is the rear surface of the bottles II.
are formed the lever S is turned to the left hand side moving the cutter horizontally
so as to operate now upon the right hand surface of the bottles while the table B
is moved forward at each fresh cut. The several surfaces or facets requiring to
be operated upon are thus successively furnished with horizontal cuts these
operations being carried out by the combined horizontal motion of the table B
actuated by the hand wheel Go, the horizontal motion of the carrier actuated by
the lever S and the vertical motion of the frames F F operated by the same
lever S', while a mixture of sand and water is constantly being fed to the cutters k k¹
through the pipes 14 by the agency of the feeding screw 15 and the elevator 2 set
in motion in the manner before described, while the fresh sand and water requi red
are placed directly by hand in the apron 16". When diagonal cuts are required
the cutter mechanism shown in Fig. 18 is made use of. For this purpose the
screws having been first released and the cotter removed the blocks i į the

page_text: cutters and the tracer ? are withdrawn and replaced by corresponding blocks
and cutter (Fig. 18) and by a similar tracer mechanism not shown on the
drawings.
In this case the spindle e carries at its lower end a bevil wheel gearing with
another bevil wheel mounted at an angle with the first wheel upon an axis
carried by the bracket 0 fixed in any suitable manner to the block, this axis
carrying the cutter ko. For vertical cuts, I use the mechanism shown in side and
end elevation in Fig. 17 in which the bevil wheels u u' are arranged at right angle
one to the other, while the cutter k may be mounted on either end of the axis as
shewn. A corresponding tracer not shown in the drawings is likewise used in
this case.
ре
After the bottles have thus been cut horizontally, diagonally and vertically they
may be transferred to another machine in order to be polished, or they may be
polished on the same machine by merely removing the cutters and replacing
them first by stone cutters and then by wood cutters or brushes of the same shape,
only water being conveyed to the last named cutters in the manner hereinbefore
described.
Fig. 5 shows another form of vacuum stool or holder which I may use as a sub-
stitute for the stool above described. AT shaped sand and water tight bearing H
is screwed into the ordinary stool H centrally hollowed for the purpose and carries
the sheet J and the bottle I.
An elliptic frame H is fixed at its lower end to the shank of the bearing H and
at its upper end to the tapped boss H5 through which moves a screw H bearing
at its lower end upon a cap H7 placed upon the bottle or decanter I under treatment
for the purpose of more securely holding the latter, while as the frame H is free
to turn round it also enables the cutter to operate without having to remove the
bottle I.
Figs. 6 and 7 are respectively a front and an end elevation of another form of stool
or holder, which consists of a slotted quadrant HP furnished with a screw H12 which
is fixed to the carrier H furnished with a platform Hs upon which the bottle I is
placed. The lower end of this carrier H turns upon a screw bolt H10 while its
upper end terminates with a horizontal arm the outer end of which is formed with
a tapped boss through which passes a screw He bearing at its lower extremity upon
a cap H' placed on the bottle I for the purpose of firmly securing the latter, on the
platform H. With this stool the bottle may as shown in dotted lines in Fig. 6, be
turned into any suitable position and held therein by the nuts fixed respectively
upon the screws H10 and H2, so that the same cutter may form rectilinear cuts in
every direction. Figs. 8, 9, 10 and 11 illustrate another form of stool. Figs. 8 and 9
being respectively a side and an end elevation thereof. Fig. 10 is a plan and Fig. 11
a sectional elevation of the carriage upon which the bottle is placed. This stool
consists of an inclined plane P the inclination of which can be regulated by means
of nuts moving on the screws n n one end of which is fixed respectively in an
extension of the flange p¹ and in the bar a while their outer ends pass through slots
formed in the support a and in the limb A which is formed integrally with the
plane P. The carriage H¹³ runs upon rails laid on the plane P and supports the
bottle I by means of a turn table furnished with a flange H and recess formed in
the circular frame H upon which the table turns. The bottle is held against a
support H arranged within the turn table and fixed thereto by a bolt H¹ provided
with a spur capable of entering one of the openings H16 of the carriage frame H¹³
according to the position in which the bottle 1 has to be placed as clearly shown
in Fig. 11, while a screw H, passing through a tapped ring or boss formed on the
upper edge of the turn table bears at its lower end against a cap placed over the
mouth of the said bottle. As the plane P may be raised or lowered according as
required, and the turn table may be likewise moved in various positions rectilinear
cuts in every direction may be formed by the cutter k on the facets of the
bottle. I.
2
The stool shown in Figs. 12 and 13 is designed to cut ornamentations on a

page_text: cylindrical bottle which is fixed up on the platform H by the screw H passing
through a boss H³ formed at the upper end of the handle H the lower end of
which is connected to a base B3°. The platform or stool H³ is rotated by the worm
gearing actuated by the pulley to which a motion is imparted by a
belt driven from the machine. The bottle is moved against the cutter by the
hand wheel H, thus forming circular cuts thereon. Figs. 14 and 15 illustrate
the holder mechanism used to cut a star or other geometrical figure upon the
underside of a bottle which is held in a bell shaped open frame H the
tubular end H, of which is held by a vertical bar H pivoting at H" upon
a standard H2 and by a frame H23 connected by an arm to the said bar; the
lower and curved ends of this last frame being slotted and attached adjustably
by a fly nut secured to a screw which is fixed to the standard H2. The
screw. He passes through the end H22 of the bell shaped frame 11200, and bears
against a placed over
of
held by the two plates or blocks H notched correspondingly to the shape of the
bottle and furnished with lugs 1º. The lugs are provided with tapped perfora-
tions through which a screw A' passes as well as through a tapped boss ²
formed on the outer edge of the opening of the frame or holder H, as clearly
shown in Fig. 15. The screw H, enables the bottle to be moved forward
and backward while the screw H23, acts as a buffer against the under surface
of the head of the screw 22, and regulates the depth of the cuts with the aid
of the articulated arm H. Fig. 19 illustrates a modified form of the machine
shown in Figs. 1, 2 and 3 and used for grinding and polishing the surfaces of
decanters and the like. To adapt the machine for such a purpose, one of the
frames F is removed, the ordinary block i is withdrawn and replaced by another
block carrying one arm of a crank shaft the other army of which passes
through the centre of a grinding disc y while its pointed end turns in an opening
formed in the step S. Zis a platform bolted to the table B and carrying
two uprights Z Z connected by a horizontal bar Z2, upon which two bottle
holders 1, can slide to and fro, being secured at their opposite sides nearest
the centre with one end of two connecting rods y³y, the other end of which is
secured to the crank shaft aforesaid. The bottle is held between the forked
ends of the holder H by a point formed thereon on one side and by a screw H
on the other, the surface of the bottle requiring to be ground being thus pressed
against the disc y² by turning the hand wheel H2 mounted upon the upper end
of a screw the other end of which passes through the cross bar of the said
holder and is screwed in a block bearing upon the bottle I.
The screw is also provided with a hand wheel H, and another wheel H",
carrying a finger H, which holds the latter in position.
The rotary motion of the spindle e and hence of the crank shaft, causes the
bottles to slide to and fro upon the grinding disc which is rotated at the same
time and surfaces the facets of the bottle, sand and water being supplied in the
manner before described.
A modification of the machine shewn in Figs. 1, 2, 3 is illustrated in Fig. 20,
the machine being in this case adapted to cut and bevel the edges of glass
plates, in imitation, as in the machine first described, of a model or pattern
which is suspended to the table arranged at the top of the machine and
supported by two pillars resting upon the horizontal edges of the flanges of the
table B. The arm a fixed to the frame F, carries a bevel tracer wheel k², as
shown, while the spindle e carries a cutter k of similar shape to that of the
tracer and operating upon the plate glass I required to be bevelled.
The latter is fixed upon a series of vacuum stools secured to the frame H
and the adjusting nuts of which are fixed against the horizontal bar M of the
said frame instead of bearing against the curved parts of the quadrants herein-
before described. The frame H is provided with two handles h h by means
of which the stools may all be removed together from one machine and to be
rapidly transferred to another.

page_text: This machine operates as follows:-The plate I being fixed to the stools H,
the cutter is set in motion and the table B is moved forward until the cutter
has travelled over the whole length of the edge of the plate. The cord or
chain A passing over the pulley A2 fixed to the frame a is subsequently pulled
down with the aid of the weight and the frame F carrying the cutter & passes
along the back edge of the plate and bevels the same assuming then the position
shown in dotted lines on the right hand side of the drawing.
When as the said table B is moved forward, causes the cutter to bevel the right
hand edge thereof. The weight attached to the cord A being now removed to the
cord As, the frame is moved back by the latter causing the cutter to bevel the
front edge of the plate and thus completing the four sides of the plate glass
the tracer wheel k² having been meanwhile pressed against the corresponding
inverted edge of the pattern to thus pushing down the weighted lever S fixed to
the spindles e ando and causing the cutter K to operate to the required depth.
With the machine just described, I may cut from a given pattern plate glass of any
desired shape.
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 machine for cutting, grinding, and polishing glass articles comprising
the frame work a slide two movable frames FF operated horizontally and
