We JOHN VICARS, THOMAS VICARS, and JOHN VICARS Junior all of 56 Scel Street
Liverpool in the county of Lancaster Engineers do hereby declare the nature of this
invention to be as follows:-
The invention relates to apparatus in which dough is caused to exude through
dies to form biscuits and the objects are to provide apparatus for cutting off the
required quantities of dough and to give the requisite motions to the apparatus. The
invention consists of
First. In combining with the dies through which the dough exudes a knife having
a forward motion at the same level as the dies and a backward motion at a higher
level.
Second. In giving motion to the said knife by means of blocks actuated conjointly
by cams and guides coupled to crank pins.
Third. In providing in combination with the reciprocating knife a vibrating check
piece for preventing the cut off dough from being carried back by the knife on its
return stroke or upset in passing on to the trays or pans.
Fourth. In combining with apparatus for making biscuits by means of dough
exuded through dies panning appliances having accelerated motion at the required.
times.
Fifth. In making the delivery end of panning appliances under the fourth head
adjustable as to height.
Sixth. In combining with apparatus for making biscuits by means of dough
exuded through dies and provided with a reciprocating knife for cutting off the
dough driving gear in which a slow forward and quick return motion is given to the
dough press.
Seventh. In combining with the improvements set forth under all or any of the
foregoing heads automatic devices for arresting the motion of the dough press at each
end of its stroke.

DESCRIPTION OF THE DRAWINGS.
Figure 1, sheet 1, is an elevation-Figure 2 sheet II a plan and Figure 3 sheet II
an end elevation of apparatus under our invention figure 4 sheet I is a sectional
view shewing the knife and driving gear.
1 frame 2 dough press of usual construction, way from the dough press to the
dies 4, 5 cutting table. These parts are of any usual or desirable construction.
Referring to the first second and third parts G is a knife secured to a har 7. The

The arms 11 are connected to springs 12 which fit within sockets 13 secured to or
formed with the blocks 8, 14 bolts for adjusting the tension of the springs. The
crank pins 10, 10¹ are carried by discs 15, 15' on shafts 16, 16' the shafts 16, 16' are
free to revolve in bearings in the frame 1; motion is given to the above parts by
means of a belt passing around one of the discs 15. The other disc 15 and the
disc 15 below are geared by abelt to ensure that they shall rotate at equal speeds in
the same direction, 17 anti friction wheels free to revolve on the ends of the bar 7
and resting on cams 18 carried by the shaft 16'. 19 check piece carried by the
frame 20. The frame 20 is coupled to levers 21, 21' pivotted at 22, 22' to the main
frame 1. The levers 20 carry anti friction pulleys 23 which rest on cams 24 secured
to the shaft 16-25 springs to keep the anti friction pulleys in contact with the
cams 26 adjusting screws.
The action of the apparatus is as follows:-
Dough is caused to exude through the dies 4 by means of pressure. The
shafts 16, 16 are caused to rotate in the direction of the arrows and the knife 6
has given to it a to and fro motion over the table 5 by means of the guide bars 9
whilst the cams 18 raise the knife 5 from the table during the time the said knife is
travelling back over the dies and the springs 13 ensure that the knife shall bear
steadily on the table during the forward motion. When the knife reaches the end
of its stroke the cams 24 allow the check piece 19 to descend as shown in figure 4
so as to prevent the biscuits cut off and carried forward by the knife from being
carried back it also serves to ensure that the biscuits are properly deposited on the
pans.
Referring to the fourth and fifth parts-27 represents panning appliances in which
the pans have intermittent motion accelerated from time to time and similar to the
apparatus for which we obtained British Letters Patent No. 3370, 13183 and 15902
of the year 1885 or any other panning appliances in which the necessary accelerated
motion is given to the pans at the required times may be used. This apparatus is
driven by gear 28 coupled to the shaft 16. The delivery end 29 of the
panning appliances is hinged at 30 so as to allow of adjustment as to height for the
purpose of bringing the pans the requisite distance from the knife when the biscuits
are being deposited on the said pans, 31 adjusting screw.
Referring to the sixth part-32 screw for giving motion to the dough press-
33 nut for actuating the screw 32, the said nut is formed or fitted with a toothed
wheel 34. The wheel 34 gears with a pinion 35 on a sleeve 36-37 toothed
wheel on the said sleeve 36 in gear with the pinion 38 on the shaft 39. The
shaft 39 is carried by rocking levers 40 and is fitted with a friction pulley 41-
42 hand wheels and shaft, 43 screwed sleeve free to slide on the said shaft but
caused to rotate therewith by means of a feather or equivalent device 44 springs
for retaining the sleeve in position 45 nut actuated by the said sleeve, 46 rod
coupling the said nut by means of rocking levers 47 to the shaft 39. 48, 481
friction pulleys carried on shafts 49, 49' the shaft 49 is provided with a pinion
50 which gears into a wheel 51 on the driving shaft 52. The shaft 49' is provided
with a wheel 53 which gears into a pinion 54 on the driving shaft 52, 55 fast
and loose driving pulleys. The action is as follows-the friction pulley 41 is
caused to bear on one or other of the friction pulleys 48, 48' by means of the hand
wheel 42 and motion is communicated from the driving shaft 52 through the
gearing 50, 51 or 53, 54 to the said pulley 41 in one or other direction and at
an increased or reduced speed according as it is desired to drive the screw 32
slowly forward and press the dough through the dies or to withdraw the said screw
rapidly when the press is to be refilled with dough.
Referring to the seventh part each end of the screw 32 is provided with cams 56
which strike against tail pieces 57 on the levers 47 so as to throw the friction
pulley 41 out of gear with the pulleys 48, 48' at each end of the stroke. The
springs 44 allow the rocking levers 47 to be moved the requisite distance to effect
this.
