PROVISIONAL SPECIFICATION:
Improvements in Masticators or Mixers suitable for the Preparation
of Linoleum and other Plastio Materials.
I, HENRY WILLIAM GODFREY, of Staines, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention to be as follows:-
end,
This masticator or mixer consists of a casing with a feeding hopper near one
and delivery orifices at the other end and within the casing there are two spiral
blocks which in transverso section have somewhat the form of an hour glass.
There are necks at the ends of the blocks which are held in bearings at the onde
of the casing. The necks at one and are geared together by a pair of toothed,
wheels. The blocks are driven and they rotate in opposite directions; they, are
Bet-ns close together as is consistent with free rotation and where they come most
nearly together the projecting parts or spiral ribs of ono block enter and fill the
hollows or recesses between the spiral ribs of the other blook,
Each block is taper being smallest at the delivery end, and the ribs each make
two complete turns in passing from end to end of the block. In short the blocks,
are spiral conus each having two (or it might be more) coarse deep threads and
similar the one to the other but the ono cone has a right hand thread and the other.
a left hand; the threads conform, and they work the one into the other.
The material to be mixed, when placed in the hopper is caught by the projections
on the two revolving blooks and is forced downwards. by them alongside the walls
of the hopper and then as in the further rotation of the blocks. the projections..
approach each other the material is squeezed between them and driven into the
casing, whence it can only escape by the delivery orifices. Before the material
reaches the delivery orifices every portion of the mass, is exposed to heavy pressure
between the projections on the blocks and the mixing results from the flow of the
material which is thus brought about.
To facilitate the feeding, rollers are provided at the mouth of the hopper one oo
either side and by gear wheels these rollers are driven in such a direction that the
material in contact with them, and more or less adhering, is carried inwards, until
in a position to be caught between the spiral blocks. Scraping blades are provided
to free the rollers from the plastic material when the rollers have carried it into
the hopper.

page_text: 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 :-
1. The improved masticator or mixer suitable for the preparation of linoleum
and other plastic materials substantially as described.
2. A masticator or mixer comprising a case with a feeding hopper at one end
and an exit aperture or apertures at the other end and containing_two_taper
twisted shafts of hour glass section engaging the one with the other and so driven
that the material is taken by them from the hopper and driven in two streams
along the two sides of the case until the streams meet and together find their way
to the exit orifice or orifices.
3. A masticator or mixer in accordance with the preceding claims and with
side rollers so driven as to aid in conducting the material from the hopper into
the case.
