PROVISIONAL SPECIFICATION.
Improvements in Breaks for Dough.
We JOHN VICARS, THOMAS VICARS, and JOHN VICARS, all of 59 Seel Street
Liverpool in the County of Lancaster, Engineers do hereby declare the nature of
this invention to be as follows
-
The invention relates to breaks or machines for reducing the thickness of, and
rendering homogeneous,-sheets of dough, by causing such sheets to pass and repass
through between rollers gradually caused to approach each other.
The main objects are to prevent accidents and to obtain efficient and easily
working driving gear.
For the prevention of accidents, a roller shaft carries by friction contact, a swing
frame provided with guard rollers, one at each end. The said frame is caused to
oscillate when the main rollers are reversed, so that one of the said rollers rests on
the sheet of dough in front of the said main rollers whichever way the said dough
is travelling towards the said main rollers.
The machine is driven by a single belt acting on a fixed pulley secured to the
driving shaft, a loose pulley, and a pulley secured to a sleeve free to revolve on the
driving shaft. The said sleeve being connected to the driving shaft by mitre
wheels.

Improvements in Breaks for Dough.
We JOHN VICARS, THOMAS VICARS, and JOHN VICARS, all of 56 Seel Street
Liverpool in the County of Lancaster, Engineers, 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 breaks or machines for reducing the thickness of and
rendering homogeneous,-sheets of dough by causing such sheets to pass and repass
through between rollers gradually caused to approach each other.
The main objects are to prevent accidents and to obtain efficient and easily
working driving gear.
For the prevention of accidents, a roller shaft carries by friction contact, a swing
frame provided with guard rollers, one at each end. The said frame is caused to
oscillate, when the main rollers are reversed, so that one of the said rollers rests on
the sheet of dough in front of the said main rollers whichever way the said dough
is travelling towards the said main rollers.
The machine is driven by a single belt acting on a pulley secured to the driving
shaft, a loose pulley, and a pulley secured to a sleeve free to revolve on the
driving shaft. The said sleeve being connected to the driving shaft by mitre
wheels.

page_text: together in any usual way. ce is the dough table. e are frames pivotted to the
shaft b and held in frictional contact therewith by means of spring clips f attached
to the said frames by pins g. hare guard rollers carried by shafts free to rotate
in bearings in the frames e. As the dough is passed to and fro beneath the
rollers a a¹ the friction clips will cause the frames e to incline in one or the other
direction so that one or other of the guard rollers h¹ rests on the sheet of dough
in advance of the said dough rollers a a¹.
By the above means the attendant is protected from the dough rollers and should
he approach too near on the entering side he will come in contact with one of the
rollers h h which will prevent him from being caught between the said dough rollers
and will owing to being held in position by frictional contact give way without
doing him any injury.
Under the second part is the driving shaft geared to the dough roller shaft b
by means of toothed wheels j. k is a pulley secured to the said driving shaft. lis
a pulley loose on the said driving shaft, and m is a pulley secured to a sleeve n free
to rotate on the said driving shaft. The sleeve n has secured to it a mitre wheel o
which gears with a mitre wheel p free to rotate on a stud carried by the frame
work of the machine. is a mitre wheel secured to the driving shaft i and gearing
with the mitre wheel p. s is a sliding bar carrying belt guides t u is a bell crank
lever pivoted to the bracket v and coupled to the sliding bar s and rock shaft arm w.
The rock shaft is carried in bearings in the frame work 9 and is provided with
sockets y for the operating handles z. When the belt is on the pulley m the shaft i
rotates in the same direction as the pulley. When the belt is on the loose pulley 1,
the shaft is stationary and when the belt is on the pulley m the shaft i rotates in
the opposite direction to the pulley as it is driven through the mitre wheels o p and r.
The belt which always travels in one direction is moved from one pulley to the
other by means of the handles z which actuates the sliding bar s.
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 :-
First. The combination with a break dough roller shaft of a swing frame carrying
guard rollers, substantially as and for the purpose set forth.
Second. Single belt driving gear for dough breaks consisting of the combination
of three belt pulleys and three mitre wheels substantially as set forth.
