Improvements in Dough Dividing Machines.
We, DIEDRICH WILHELM ATGUST HAAGEN and FRIEDRICH KARL AUGUST
WILHELM RINAU, Manufacturers, of 50, Schlachthofstrasse,. Bremen, in tho
Empire of Germany, 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:-
This invention relates to an improved dough dividing machine whose essential
feature consists in the arrangement of the constituent parts so that the machine
can be dismounted without the use of a tool.
In machines of this kind it is absolutely necessary that the constituent parts
be frequently cleaned, in order that the dough be not soiled and that at the
same time the machine be not impeded in its function by the dough. The con-
stituent parts of the machine therefore are according to the invention so con-
structed as to permit of being readily dismounted without the use of a tool. The
several connecting rods used in the machine are for this purpose connected by
bolts retained in position by a transverse bolt which, by imparting to it half a
turn will release the connecting bolt, thus enabling the latter to be removed out
of its bearing, without the use of a tool. The knife blades or systems of blades are
by appropriate devices likewise so secured to the machine as to admit of being
mounted and dismounted without any tool, and if necessary, with one hand only.
The knife blades are fixed by securely connecting them with bolts arranged in
tubular blade holders, the said bolts being provided with specially constructed
heads adapted to fit into slots or recesses of flanges arranged on the system of
blades and into forked-shaped heads of the tubular blade holders so that by pro-
perly turning a plate connecting the said bolta, by means of a lover, the system
of blades is either fixed or released.
The fixing of the system of blades may also be effected by arranging the blade
holders upon a rotary ring, the top ends of the said holders being provided with
notches or slots so that on turning the ring in one direction the holders engage
with hook-shaped projections on the blades, thus establishing a connection between
the blades and the blade holders; while on turning the ring in the other direction
the blades are released.
The stroke of the blades is preferably limited by the aid of one or more down-
wardly directed bolts provided with a longitudinal slot. The bolt projects through
the bed-plate of the dough dividing machine and is adapted to move therein in
vertical direction. On the bed-plate a centrical ring is rotatably arranged, the
same being provided with hooks which, on turning the ring, engage with the
slots of the bolts aforesaid. In this manner the stroke of the knife blades can
be limited and admit of being accurately adjusted by suitable means.
The invention is represented in the accompanying drawing, in which
Figure 1 is a section through the top part of a dough dividing machine,
Figure 2 is an elevation looking in the direction indicated by the arrow
(Figure 1).

As illustrated in Figures 6, 7, 8, 9, 9, 9b, the system of blades a is connected
with the bed plate b, by means of tubular blade holders c. The system of blades a
is furnished with recessed lugs or flanges d (Figure 9) which are adapted to fit
into the fork-shaped heads f of the blade holders c. In the tubular blade holders c
the bolts g (Figure 9) having elongated heads h, are arranged, which are capable of
being moved into the recesses in the lugs or flanges d. According as the fastening
or unfastening is to be effected between the flanges of the system of blades and
the blade holders c, the elongated heads h are placed parallel with the flanges d
or transversely thereto, whilst the movement of the heads h or bolts g respectively,
with the hollow blade holders c is provided in the following manner:--
Around the bed plate & an annular plate is movably arranged which is guided
by pins or screws m acting within slots k. Below this plate the levers o. provided
with slots n, are arranged and serve for connection with the bolts g. The bolts g
are at this place furnished with a square and the levers o are connected with the
plate by pins p. If now the plate is displaced laterally by means of the handle
the bolts are turned through an angle of about 90° by the levers o so that the
elongated heads h of the bolts g either effect engagement or disengagement between
the Hanges of the system of blades and the blade holders c.
The fixing of the system of blades to the blade holders may also be such that
the fastening is effected directly by displacing the blade holders which are arranged
on the rotary ring of the bed plate and which, by turning the said ring, can be so
displaced that in one position they engage with corresponding notches over hooks
arranged on the system of blades; whereas in the other position they are thrown
out of engagement.
As illustrated in Figures 1, 2, 3, 4, 5, 5 the blade holders care provided directly
on the ring which can be turned by the handle, upon the plate in the manuer
before described. The upper extremities of the blade holders care furnished with
transverse slots in which hook shaped projections (Figures 5, 5') are adapted to
enter. If the blades a guided in the known mauuer, are to be connected with the
blade holders c¹, the ring with the blade holders c is so turned, that the slota
of the latter slide on to the hooks d' of the blades. If the system of blades is to
be taken out for cleaning, the ring is turned in the opposite direction, so that
the books dare thrown out of engagement with the slots of the blade holders and
the blades may thereby be taken out.
For the purpose of limiting the stroke of the blades, bolts are secured to the
system of blades, the said bolts being furnished with longitudinal slots f. These
bolts traverse the plate b and 6' respectively. On the ring and i respectively
hooks are provided the extremities of which upon turning the ring i or it for the
fixture of the blades engage with the slots of the bolts s. Thus as the blades are
lifted, the engaging hooks strike against the lower end of the slot guide so that
the blades are prevented from further rising. Into the bolt sa screw e (Figure 2)
is screwed in longitudinal direction from below, this screw projecting into the
slot and thus enabling the stroke of the blades to be adjusted to the proper
height.

The several connecting rods of the machine are pivotally fixed in their bearings

page_text: by means of bolts ir. These bolts are of cylindrical shape throughout and are
provided with a flat recess toward their bottom end. Into this recess fils a locking
holt passing transversely to the bolt w and thus preventing the bolts from leaving
their bearings. This locking bolt is likewise recessed upon one side, so that on
turning the bolt through an angle of 180° the bolt i can be taken out of its
bearing.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is: --
1. A dough dividing machine dismountable without the use of a tool, the
characteristic feature being that the connecting rods are connected in their bear-
ings by means of bolts r having a cavity arranged near their ends in which cavity
fits a locking bolt r which is upon one of its sides likewise provided with a corres-
ponding cavity or recess so that on turning this bolt r through an angle of 180°
the bearing bolt r can be dismounted without the use of a tool.
2. In a dough dividing machine as herein before described a device for limiting the
stroke of the system of blades, the characteristic feature being that on the system
of blades downwardly directed bolts s are arranged presenting a longitudinal slot t
and being passed through the bed plate b 6' so that hooks fixed to a ring adapted
to rotate around the bed plate 6' will, upon turning this ring engage with the
slots of the bolts and thus limit the stroke of the system of blades by contact
with the bottom edges of the slots.
3. In the device covered in the preceding claim, an arrangement presenting this
characteristic feature, that into the lower end of the bolt a screw is adjusted
longitudinally so as to project into the slot f and so that as this screw is turned up
or down the stroke of the system of blades a' can be regulated.
4. In a dough dividing machine as hereinbefore described, an arrangement pre-
senting this characteristic feature, that the system of blades a is detachably con-
nected with bolts g located in tubular blade holders c, the bolts g being provided with
heads adapted to fit into recesses or slots of the flanges in the system of blades,
and into fork-shaped heads f of the tubular blade holders c, so that by a correspond-
ing rotation of a plate i to which the bolts g, are connected by means of levers o,
the system of blades is either fixed or released.
5. In a dough dividing machine as hereinbefore described the airangement
according to which the blade holders c¹ are arranged upon the rotary ing and
have their top end provided with transverse slots which, upon turning the ring
in one direction engage with hook shaped projections on the blades, thus estab-
lishing the connection between the blades and the blade holders, while on turning
the ring in the other direction they will disengage.
6. Dough dividing machines constructed and operating as and for the purposes
hereinbefore described.
