CHARLES WARREN 13 Fore Street Ipswich in the county of Suffolk, Engineer, do
hereby declare the nature of this invention to be as follows:-
Within a cylindrical chamber provided with a suitable hopper for receiving the
vegetables I place a screw which is revolved in the said cylindrical chamber by means
of an ordinary crank & handle at the end of the cylinder I attach a perforated or
wire woven disc the said discs are by a suitable device removable.
The vegetables being placed in the hopper are taken and carried forward by the
said screw and thereby forced through the disc.

page_text: following statement :—
My invention relates to machines for mashing potatoes and other vegetables and 5
making bread crumbs, and for similar purposes, and has for its object to provide a
machine which can be operated continuously.
In the accompanying drawing
Figure 1 is a front elevation of a machine constructed according to my invention.
Figure 2 is a side elevation, and
Figure 3 is a vertical section on the line x, x, figure 1.
a is a barrel or cylinder and 6 is a spiral compressor which is located in the said
chamber and mounted upon a shaft c journalled in a bearing d formed integral with
the barrel.
1
The barrel a has also formed integral with it a standard e upon which it is supported 1
and a hopper through which the material to be operated upon is introduced into
the machine.
g is the handle for rotating the compressor, the said handle being secured to the
shaft c by a nut h.
i is a metal disc of wire gauze or other suitable material through which the
vegetable or other material is forced by the compressor in order to effect the mashing
or crumbling of the same. This disc is held in position by a metal ring ; which
overlaps the edge of the said disc and clamps it against the end of the cylinder a.
In order to prevent the disc from being forced from between the said ring and the
end of the cylinder it is secured to a ring or flange k which surrounds the end of the
said cylinder as shown in figure 3.
The ring is held in place by means of the swivel bolts I attached to the cylinder a
and having the nuts m. The said nuts bear upon the lugs n on the ring ; which lugs
are slotted as shown in figures 1 and 2, so that after the nuts have been loosened they
may be moved with the bolts out of engagement with the nuts to enable the removal
of the ring and the disc i.
To effect the removal of the spiral compressor b it is only requisite to remove the
nut and the handle g, when the said compressor can be drawn out of the cylinder
through its open end.
It is to be understood that the meshes or perforations of the disc i may be of any
required size according to the degree to which the mashing or crumbling is to be
effected:
The operation of my improved machine as follows, that is to say, the vegetable
or other material is introduced into the hopper f from whence it passes into the
cylinder a. As the compressor is rotated the said material is pressed against the

page_text: disc i and through the openings therein whereby it is reduced to the required degree
of fineness: It will be noticed that the edge 61 of the compressor moves in close
proximity to the disc and thereby facilitates the forcing of the material through
the same.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. A machine for mashing vegetables, and for similar purposes, comprising the
cylinder a having the hopper, the spiral compressor adapted to rotate in said
cylinder and the disc i substantially as described.
2. The combination with the cylinder a and the disc i having the flange or ring k
of the ring ; adapted to secure the said disc in position, substantially as described.
3. The improved machine consisting of the parts constructed and combined,
substantially as described with reference to the accompanying drawing and operating
as, and for the purpose, setforth.
