PROVISIONAL SPECIFICATION.
New and Improved Machinery for the Liquidizing Process in the
Manufacture of Enamelled Plates or other similar Surfaces.
I RUPERT BENJAMIN BAUGH, of Erceldeane, Wake Green Road, Moseley, in the
county of Worcester, Gentleman, do hereby declare the nature of this invention to
be as follows:-
This invention relates to an improved arrangement of mechanism, whereby plates
or other surfaces of a similar character, may be evenly coated with liquid enamel, or
other analogous substance, and is primarily intended for use in the liquidizing process,
or stage, of the manufacture of enamelled sign or other similar plates; and its object
is, to minimize the hand labour required in such manufacture, and to ensure greater
uniformity and an improved quality of work, than is attainable by the methods now
in use.
It consists of a long table support or slide frame, having upon it, grooves or their
equivalents to receive a sliding table, capable of a to and fro longitudinal motion,
similar to that of an ordinary planing machine, and driven by fast, loose, and reversing
pulleys &c., in combination with a rack and pinion, or other equivalent mechanism.
The sliding table is constructed preferably of a light framework of iron, say for
instance of angle iron, of an openwork character, thereby permitting any superfluous
fluid enamel to fall therethrough into a receiving well below.
At the one side of the table support or frame, and about midway thereat, a strong
standard is provided, which rises upward and above the aforesaid table. To this
standard is attached an overhanging cistern or tank; it being thus overhung, in order
to afford a free access to the entire one side of the machine.
In the lower part of the cistern, discharging rollers are provided, and fitted with
gear wheels at their ends, in order that they may roll inwards towards each other.
Further, these rollers are driven by means of a varying speed cone, so that from time
to time, as may be desired, their speed of rotation may be changed. Or, in some
cases if desired one of such rollers only may be used, acting in conjunction with a
gauge plate. An approaching or receding adjustable feed mechanism is provided,
whereby the quantity of liquid discharged, may be varied at will.
Within the aforesaid cistern, and near above the discharging rollers, an agitator or
stirrer is provided, which may consist of one or more rotating spindles, carrying
prongs, forks, studs, or other projections, suitably arranged both as to their motion
and disposition, to thoroughly stir up and agitate the liquid, in order to prevent it
solidifying or becoming dry or lumpy. This agitating mechanism may be driven by
the same mechanism that drives the discharging rollers, or it may be provided with
a separate driving mechanism.
At the upper part of the cistern, a sieve or perforated plate is provided, through
which the fluid enamel is poured therein.
Upon the plates &c. to be coated being suitably arranged upon the table, and the
machine put in motion, the liquid in the cistern is uniformly discharged through the
rollers on to the said plates as they travel forward, any surplus liquid falling therefrom
into a well beneath the table. Å suitable stopping or starting gear is provided by
which the machine can be stopped, reversed, or restarted, at any point in its travel,
such gear being further arranged that upon the arrival of the table at either end of
its travel, it will be automatically brought to a standstill.
A rod is carried from end to end of the frame, which communicates motion to a
sliding belt fork at the driving pulleys, so that at whatever point along the side of the
machine the operator may happen to be, he can by means of the said rod, throw the
belt on or off the loose pulley, and so stop or start the machine.

page_text: Again, at certain distances from each other along the frame, transverse weigh shafts
are provided, having at their both ends, short levers, which come beneath the sliding
table. Also upon such weigh shafts are vertical levers, which are connected to each
other along the whole length of the machine, by means of connecting rods. Upon
the end shaft is further provided an horizontal lever, to the outer end of which, is
connected a vertical rod, communicating at its other end with a crank piu upon a
rotating shaft, overhead or below, as may be most convenient, so that upon a quick
rotating motion being given to the crank, a rapid up and down or shaking motion is
imparted to the aforesaid short levers, and thence to the table upon which the plates
are carried. This is an important feature in this my invention, inasmuch as this smart,
shaking operation, levels down any unevenness which may have been produced, of the
liquid upon the plates. This mechanism is also provided with a stopping and starting
gear, so that at any point in the travel of the table, or at either end of its travel, such
shaking motion may be given thereto.
Further, during this process, some portion of the fluid discharged from the cistern,
runs off the plates, or otherwise falls when the plates are not beneath, or falls between
the, plates; and it is desirable that this should be returned to the cistern for future
use. To effect this, I provide as before intimated the lower well, into which it may
fall. From this well, it is carried upwards to the top of the cistern by means of
elevators or travelling buckets, carried upon an endless band.
These buckets are hung upon pivoted ends, so that upon reaching a point above a
shoot attached to the cistern, they will strike an overhanging stud, and so tip their
contents into the said shoot, and thence to the cistern.
It may occur however thut during such process, the liquid may become somewhat
lumpy, in which state it is desirable that it should not pass direct into the cistern ;
therefore a rotary brush is provided, the lower surface of which, sweeps upon the
aforesaid perforated sieve in the cistern, and thus breaks up any such lumps.

New and Improved Machinery for the Liquidizing Process in the
Manufacture of Enamelled Plates or other similar Surfaces.
I, RUPERT BENJAMIN BAUGH, of Erceldeane, Wake Green Road, Moseley, in the
county of Worcester, Gentleman, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularlydescribed and ascertained
in and by the following statement :-
This invention relates to an improved arrangement of mechanism, whereby plates or
or other surfaces of a similar character, may be evenly coated with liquid enamel, or
other analogous substance; and is primarily intended for use in the liquidizing process
or stage, of the manufacture of enamelled sign or.other similar plates; and its object
is, to minimize the hand labour required in such manufacture, and to ensure greater
uniformity and a better quality of work, than is attainable by the methods now in use.
In order to better explain this my said invention, I have appended hereunto au
illustrative sheet of drawings upon which are figures and letters of reference, similar
letters referring throughout the several views to the same thing or part.
Fig. 1, shows a general side elevation of a machine illustrating some of these my
improvements.
Fig. 2, is a part plan showing the reciprocating table, and driving gear &c.
Fig. 3, is a general end view of the machine.
Fig. 4, is a sectional detail showing arrangement of supply cistern.
Figs. 5 & 6, is a detailed elevation and a plan of the elevating buckets, used for
replacing the superfluous or overflow liquid enamel in the cistern.
is a long table, support, or slide frame, having upon it, grooves or their

page_text: equivalents, to receive a sliding table b, capable of a to and fro longitudinal motion,
similar to that of an ordinary planing machine, and driven by fast, loose, and
reversing pulleys c, c, c, &c., in combination with the wheels d, and e, and the chain
drum f, and chain g, see Figs. 1 & 2, or it may in some cases be worked by a rack
and pinion, or other equivalent mechanism.
Upon the sliding table b, is placed the plates &c. to be coated. The sliding table is
constructed preferably of a light framework of iron, of an openwork character, such
for instance as seen in Fig. 2, thereby permitting any superfluous fluid enamel which
may run off the plates to fall therethrough into a receiving well h, below.
At the one side of the support frame a, and about midway thereat, a strong
standard i is provided, which rises upward and above the aforesaid table b. To this
standard is attached an overhanging cistern or tank j, it being thus overhung, in
order to afford a free access to the entire one side of the machine, as seen in
Figs. 1 and 3.
In the lower part of this cistern j, discharging rollers k, l, are provided, and fitted
with gear wheels m, at their ends, in order that they may roll inwards towards each
other. Further, these rollers are driven by means of a varying speed cone n, so that
from time to time, as may be desired, their speed of rotation may be changed. Or, in
some cases if desired, see Fig. 4, one of such rollers k¹, only, may be used, acting in
conjunction with a gauge plate o. An approaching or receding adjustable feed
mechanism is provided, whereby the quantity of liquid discharged, may be varied at
will. The rollers k, and l, are carried in bearings p, which are capable of a sliding
motion in the slot q. r, is a handwheel which rotates the shaft s. Upon this shaft 8,
is mounted the bevil cog wheels t, t, which gear into the bevil cog wheels u, u, which
latter communicates with the bearings of the roller k, by means of a screw or other
suitable device. Thus upon turning the hand wheel r, the cog bevil wheels impart a
backward or forward motion to the bearings p, and thus open or close the rollers
towards or from each other, thereby regulating the supply of the enamel in quantity.
Within the aforesaid cistern j, and near above the discharging rollers, an agitator
or stirrer v, is provided, see Figs. 3 & 4, which may consist of one or more
rotating spindles, (one only is shown) carrying prongs, forks, studs, or other projec-
tions, suitably arranged both as to their motion and disposition, to thoroughly stir up
and agitate the liquid, in order to prevent it solidifying or becoming dry or lumpy.
This agitating mechanism may be driven by the same mechanism that drives the
discharging rollers, or it may be provided with a separate driving mechanism,
according to convenience.
At the upper part of the cistern j, a sieve or perforated plate w, is provided,
through which the fluid enamel is poured into the said cistern.
Upon the plates &c. to be coated, being suitably arranged upon the table b, and
the machine put in motion, the liquid in the cistern j, is uniformly discharged
through the rollers k, l, or k, on to the said plates, as they travel forward, any surplus
liquid falling therefrom into the well h, beneath the table. A suitable stopping or
starting gear is provided, by which the machine can be stopped, reversed, or restarted,
at any point in its travel, such gear being further arranged that upon the arrival of
the table at either end of its travel, it will be automatically brought to a stand
still.
A rod, Fig. 1, is carried from end to end of the frame a, which communicates-by
means of the bell crank y,-motion to a sliding belt fork z, at the driving pulleys, so
that at whatever point along the side of the machine the operator may happen to be,
he can by means of the said rod x, throw the belt on or off the loose pulley, and so
stop or start the machine. The automatic stopping of the machine at each end of its
travel is effected by means of the adjustable stop pieces a³, a', which can be placed
anywhere along the rod to accommodate the stroke or travel of the table.
Again, at certain distances from each other along the frame, transverse weigh
shafts b', are provided, having at their both ends short levers c', which come beneath
the sliding table b. Also upon such weigh shafts are vertical levers d', which are
connected to each other along the whole length of the machine, by means of con-
:

page_text: necting rods e¹. Upon the end shaft is further provided an horizontal leverf, to the
outer end of which, is connected a vertical rod g', communicating at its other ond
with a crank pin h¹, upon a rotating shaft, overbead or below, as may be most con-
venient, so that upon a quick rotating motion being given to the crank, a rapid up
and down or shaking motion is imparted to the aforesaid short levers c', and thence
to the table b, upon which the plates are carried. This is an important feature in this
my invention, inasmuch as this smart shaking operation, levels down any unevenuess
of the liquid which may have been produced upon the plates. This mechanism is also
provided with a stopping, and starting gear, by fast and loose pulleys l', & m', so that
at any point in the travel of the table, or at either end of its travel, such shaking
motion may if necessary be given thereto.
Further, during these processes, some portion of the fluid discharged from the
cistern, runs off the plates, or otherwise falls when the plates are not beneath, or
falls between the plates &c., and it is desirable that this should be returned to the said
cistern for future use. To effect this, I provide as before intimated, the lower well h,
into which it may fall. From this well, it is carried upwards to the top of the cistern
by means of elevators or travelling buckets n', carried upon an endless band o¹.
These buckets are hung upon pivoted ends, so that upon reaching a point (see Fig. 3)
above a shoot p', attached to the cistern, they will strike an overhanging stud ql, and
so tip their contents into the said shoot, which carries them back to the cistern j.
It may occur however that during such latter processes, the liquid may become
somewhat lumpy, in which state it is desirable that it should not pass direct into the
cistern; therefore a rotary brush r', is provided, the lower surface of which, sweeps
upon the aforesaid perforated sieve w, in the cistern, and thus breaks up any such
lumps, when it will then pass into the cistern.
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 as my improvements in machinery for the liquidizing process in the manu-
facture of enamelled plates or other similar surfaces, is :-
