PROVISIONAL SPECIFICATION.
Improvements in Apparatus for use in the Manufacture of Bread.
I, JOHN ADAIR, Commission Agent, Waterford, Ireland, do hereby declare the
nature of this invention to be as follows:-
-
In the Specification of my Patent No. 15,14389 I shew an upright dough box.
Now as the shape of this machine has corners in it which corners are always more
or less difficult to clean as the dough will stick more into a corner than in an open
space, I make as an improvement in the construction of such box a box which has no
corners in it whatsoever.
I do not confine myself to the width or length now specified by the drawing
enclosed.
For instance, the box might widen itself until it would be a perfect circle, or it
might narrow itself until it would be more of an oval, than that now represented
in the drawing-but in either case it would be upon the lines of my construction
which is a box without any corners, made either circular or oval.
Further in the construction of such upright dough-boxes, I make them of two
metal castings bolted together-after the manner shewn in the drawings.
This mode of construction will materially reduce their cost, and add considerably
to their durability and exactness of working-it being evident that it is much
easier to cast a box such as I describe than to form it with wrought iron or other
material, and 2ndly if formed of wrought iron or other material, there would be a
great difficulty in keeping it to the exact smoothness and correctness of lines, as
can be done with the metal. Also for durability and cleanliness I much prefer
metal where water is used-to wrought iron.
Further as a method of cleaning such dough-boxes, I put into them the arm, as
represented in drawing and also indicated by the dotted lines in box. This arm
working at the top of the box, is a great advantage, in comparison to working at
the bottom or sides-for whatever dough would be scraped off either the bottom or
the sides, would clog around the scraper, while a scraper working at the top, owing
to the dough falling the moment it gets into any bulk, cannot clog.
I have the power of preventing this scraper from working, by the pin, as shewn
in drawing, which tightens it up.
Further, I work this dough-box after the manner described in the Specification
my Patent No. 15,14380 with rods, and also by the method of machinery there
described and further I also work it by a rope pulley, or it may be belt or chain
directly off of the shaft, which carries the dough box; and when I work it by this
method I increase the velocity and thus have the power of doing away with rods
altogether in the machine.
The advantage of this latter method of working will accomplish two things-
1st. It will be a noiseless machine, which will be a great advantage in a bakehouse
where space is frequently limited & from the nature of the business noise is
decidedly objectionable.
2nd. It will very much reduce the cost of construction, not to speak of wear and
tear. The advantage of having no rods in the machine will make it exceedingly
easy to clean and also add further to the cheapness of construction.

The dotted lines in box represent the scraper-as shewn in Fig. 2. P is the pin,
for tightening such scraper when it is not required to work.
This pin passes from the dough-box into a hole which is in the weight W, and
thus keeps it from moving.
The weight W. is for the purpose of keeping the scraper in an upright position
and can be shifted by means of a set-screw.
Fig. 2. is the scraper, which is made of iron, with moveable steel scrapers on it,
shewn at N. N. N. these by means of set-screws to be put to any desired pitch.

I may remark that when I work this machine with rods in it-I take out such
rods, when I am cleaning-in order to permit the scraper to work.
The scraper is fastened into the box by the pin O.
This pin is kept stationary
by being screwed into the box, and there is a moveable collar on it, which permits
the scraper to be taken off or on.
The scraper can be taken asunder, by means of the bolts Z. Z.
COMPLETE SPECIFICATION.
Improvements in Apparatus for use in the Manufacture of Bread.
I, JOHN ADAIR, Commission Agent, Waterford, Ireland, 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:-
In the Specification of my Patent No. 15,14389 I show an upright dough box.
Now as the shape of this machine has corners in it, which corners are always
more or less difficult to clean as the dough will stick more into a corner than in an
open space-I make as an improvement in the construction of such box a box that
has no corners in it whatsoever. I do not confine myself to the width or length now
specified by drawing enclosed-for instance, the box might widen itself until it
would be a perfect circle or might narrow itself until it would be more of an oval
than now represented in the drawing, but in either case it would be upon the lines
of my construction which is a box without any corners made either circular or oval.
Further in the construction of such upright dough boxes, I make them of one
metal casting after the manner shewn in the drawings. This system of constructing
them, will materially reduce their cost and add considerably to their durability and
exactness of working, as it is evident it is much easier to cast a box such as I
describe, than to form it with wrought iron or other material, and secondly if formed
of wrought iron or other material there would be a great difficulty in keeping
it to the exact smoothness and correctness of lines, as can be done with the
metal.
Also for durability and cleanliness I much prefer metal where water is used-to
wrought iron.
Further, as a method of cleaning such dough boxes, I put into them the arm
scraper as represented in drawing. This arm-scraper working at the top of the box,
is a great advantage in comparison to working at the bottom or sides, for whatever
dough would be scraped off either the bottom or the sides would clog round the
scraper while a scraper working at the top, owing to the dough falling the
moment it gets into any bulk, cannot clog. I have the power of preventing this
scraper from working by the pin-as shewn in drawing, which tightens it up.
Further, I work this dough machine after the manner described in the Specifi-
cation of my Patent No. 15,14389 with rods, and also by the method of machinery
there described and further, I also work it by a rope pulley, or it may be, belt or
chain, directly off the shaft, which carries the dough box-and when I work it by
this method I increase the velocity, and thus I have the power of reducing the

page_text: number of rods, or for some light doughs, doing away with them altogether in the
machine.
. The advantage of this method of working will accomplish two things-
1st. It will be a noiseless machine which will be a great advantage in a bake-
house-as for the method of work carried on there, it is desirable to avoid noise
and confusion-the space being frequently very limited.
2nd. It will very much reduce the cost of construction, not to speak of
wear & tear, and the advantage should light dough be only worked of having no
rods-
sor with a stiff dough a reduced number of rods in the machine will make it
exceedingly easy to clean, and also further add to the cheapness of construction.
The sponge-blender is placed in this machine in top-door suspended by two pivots
upon which it swings, the swing is allowed to be sufficient to give it a slight jerk,
and thus assist in shaking off any sponge that may be sticking to the wires.
This swing is adjusted by projecting bolts in box.
The advantage of placing sponge-blender in top-door is-that any dripping from
it when taking it out will fall into machine-also the method of putting it in there,
will be easier and quicker than at side-door-indeed there will be no necessity now
to open the side door at all, except for the inspection of the machine, or possibly
to give it a rub out with the hand when cleaning. Of course in this machine the
sponge and flour will be thrown in through the top-door from the loft over the
machine.
The rods in this machine I take in and out as described in drawing which will be
a great advantage in cleaning, also a very thin wire can be used in dough making,
which is a further advantage.
The arrangement for fastening doors is important as with a side door I can take
it off while the box is in motion, and with a top door I can set it to any position.

page_text: frame of box, for these to enter into. Of course the Indian rubber goes outside the
slot, so as to make a perfect close joint.
Fig. 2. is a full sized view, shewing the manner in which the door K. Sheet 2.
Fig. 1. is tightened.
The tightening pin N. works on the plate U as indicated by the arrow at its
entrance V. there is a bevel cut on the plate U. which makes it say one quarter of
an inch lower than the opposite side W. thus the pin N. gets an entrance at V.
when it passes off at W.
It will be observed that in the position in drawing, N. is quite free from the
plate U. therefore this shows a quick, easy and durable method of tightening the
side door K. or opening it.
Fig. 3. is a full sized view of the method of tightening rods.
1. is hook.
2. is shoulder on same inside which shoulder there is an Indian rubber ring, though
not shewn in drawing.
3. is brass plug, screwed. into dough box-through which this hook passes. The
hole in this plug is square, and the hook at its shoulder is also square, therefore
prevented from turning in plug. This plug is screwed tightly into the dough box,
to prevent its turning.
4. is an Indian rubber ring.
5. is a brass washer.
6. is a screw handle which draws the hook out & thus tightens rod, or in like
manner slackens same.
7. is a hole in hook for a check pin to pass through, so as to keep the handle 6.
from screwing off.
8. is hook on the opposite side which is screwed into the dough box by means of
the nut 9 and held there firmly into position.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed-I wish it to be
distinctly understood, that I do not confine myself to the precise dimensions or
relative proportions of the several parts hereinbefore described-it will be readily
seen that these may be considerably varied, without departing from the invention-
but what I claim is-
1st. A dough machine after the manner described in this invention and further
illustrated by drawings attached, Sheets No. 1. 2. & 3.
2nd. The oval or circular construction of such machine, and the method by
means of one metal casting of forming same.
3rd. The arm scraper, also method of fixing and removing rods—as illustrated
Sheet 3. Fig. 3.
4th. The method of driving such machine by means of pulley on main shaft,
also the arrangements for fixing doors, as described and illustrated. Sheet No. 1.
Fig. 2. Sheet No. 2. Figs. 1 & 2. Sheet No. 3. Fig. 2.
5th. A sponge blender as applicable to this machine, constructed of one casting-
with half circles on same, upon which wires run and are strained by tightening pin
and method of fixing same in dough box.
Signed this 8th day of the 9th Month 1891.
