IMPROVEMENTS IN KNEADING AND MIXING MACHINERY
Year: 1884

page_text: I PAUL PFLEIDERER of 37 Farringdon Street in the City of London Engineer
do hereby declare the nature of my Invention for IMPROVEMENTS IN KNEADING
AND MIXING MACHINERY to be as follows:-
My Invention consists chiefly in so working out adapting and modifying the
Machine illustrated by Fig 9 Sheet 2 of my Patent No 2953 dated 20th July 1876
as to make a somewhat cheaper and simpler Machine than the above alluded to for
the
purpose of kneading mixing and beating softer kinds of dough or other more or
less liquid semi-liquid pulverized or granulated materials.
For that purpose I combine with such revolving pan one or more mixing blades
somewhat like those illustrated in Fig. 1, 2, 4 & 5 of Sheet 7 of my Specification
No 5330 dated December 31st 1878 i.e. blades with only one journal at the driving
end but without any support or bearing in the opposite or far end, as is illustrated
by Figs 5 and 6 Sheet 6 of my Specification 533078 and I wish to have it understood
that I want to include all the fundamental shapes of blades under my various
former Patents such as those illustrated by the various drawings of my Specification
No 5003 of Dec: 1-1880 only so modified as to have no second support, or bearing
on the outer end and to deviate so far from the original form of their circumference
as is necessary to make them more or less touch the walls and bottom of the
revolving pan Such blade or blades hang or project into the revolving pan either
vertically or at some convenient incline and have their shafts or journals passed
through supports or bearings on a fixed stationary standard outside the pan. They
are driven either from the same source of power or from one independent of that
which moves this revolving pan.
When I employ two or more such blades I work them either at equal or at
different speeds either with or without the Bridge G. between them. In the former
case such bridge is firmly connected with the Standard and forms a sort of sliding
piece or scraper on the revolving pan.

page_text: PAUL PFLEIDERER, 86 Upper Ground Street, Blackfriars London S.E. Engineer,
late of 37, Farringdon Street London E.C. do hereby declare the nature of my
invention for "IMPROVEMENTS IN KNEADING AND MIXING MACHINERY," and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
I construct the Machine Fig. 9 Sheet 2 of my Patent No 2953, dated 20th July
1876 with one or more blades similar to those illustrated in Figs. 1, 2, 4 and 5,
sheet 7 of iny Patent Nº 5330, A.D. 1878, but I omit one support or bearing of each
Blade leaving it to be supported on the driving end only, instead of supporting both
ends by bearings as illustrated Figs. 5 & 6, Sheet 6 of my Patent No 5330 of 1878.
I also use either of the shapes of Blades illustrated by the various drawings of my
specification No 5003 of Dec. 1st 1880, all so adapted or modified as to have no
second support or bearing and to deviate from the original Blades in the form of
their circumference as far as is necessary to make them touch the walls and bottom
of the trough P or pan P. To that end-I hang or project my Blades B into the
revolving pan P vertically or at some convenient incline and have their shafts or
journals supported in bearings or fixed stationary standards S outside the pan P
driving them independently or from the same source of power which moves the pan.
Fig. 1 on accompanying drawing is a vertical section, dotted lines showing how the
Blade or Blades B are lifted out of the pan P. Figs. 5 & 6 are copies from my
previous specification but modified as above described.
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
A Machine with a revolving pan or trough and one or more mixing Blades, each
with only one bearing, so hanging or projecting into such pan as to be easily
removed for cleaning, such pan and mixing blades being of the shape and revolved
in the manner above stated.
