I JOHN ROBERT ALSING of 27 Leadenhall Street in the City of London,
Manufacturer, do hereby declare my invention to be as follows:-
:-
My invention relates to the construction of Triturating cylinders in which the
lining forming the grinding surface is composed of blocks or plates, and the object
being to provide simple and effective means of holding or fastening the said blocks
or plates firmly together.
And in order that my said invention may be understood I will refer to the drawings
accompanying this specification in which Fig. 1 (sheet I) represents a horizontal
section of a cylinder constructed according to my said invention, Fig. 2 shews one of the
circumferential plates or blocks, Fig. 3 shews section of same through line a. b. and
Fig. 4 section through line c. d. Fig. 5 shews view of one of the end plates. Fig. 6
end view of same. Fig. 7 section through line e. f. Fig. 8 (sheet 2) interior end
view of cylinder. Fig. 9 cross section, and Fig. 10 outside view.
r.
At each of the above Figs. I employ the same letters to denote the same parts.
A shews the circumferential plates or blocks B end plates or blocks C keys hereafter
described, D opening to enable last plate to be inserted. As will be seen on reference
to the drawings the circumferential plates or blocks A are formed with tongues a and
grooves b extending for a greater part of their length as shewn in Fig. 3 and the ends
are formed with grooves as shewn in the section at Fig. 4, the end plates or blocks
are formed as shewn at Figs: 5. 6. and 7.
In order to construct a triturating cylinder of blocks or plates formed as above
described, I slide the tongue a of one block or plate into the groove 6 of the other I
then secure all the plates or blocks together lengthwise by inserting the keys C into
the slots formed by the grooves 6 coming together as shewn in section Figs. 1 and 9.
The end plates, B are also held together by the tongue a on one plate or block fitting
into the groove b on the next.
The plates or blocks may be made of chilled cast iron or other suitable material, so
as to form a hard and durable grinding surface.

page_text: I, JOHN ROBERT ALSING of 27 Leadenhall Street in the City of London,
Manufacturer do hereby declare the nature of my said invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement :-
My invention relates to the construction of triturating cylinders in which the lining
forming the grinding surface is composed of blocks or plates and the object being to
provide simple and effective means of holding or fastening the said blocks or plates
firmly together.
And in order that my said invention may be understood I will refer to the drawings
accompanying the provisional specification in which Figure 1 (sheet 1) represents a
horizontal section of a cylinder constructed according to my said invention, Figure 2
shews one of the circumferential plates or blocks, Figure 3 shews section of same through
line b and Figure 4 section through line c d. Figure 5 shews view of one of the
end plates, Figure 6 end view of same. Figure 7 section through line e, f, Figure 8
(sheet 2) interior end view of cylinder, Figure 9 cross section and Figure 10
outside view. At each of the above Figures I employ the same letters to denote
the same parts.
a,
A shews the circumferential plates or blocks, B end plates or blocks, C keys here-
after described, D opening to allow last plate to be inserted. As will be seen on
reference to the drawings the circumferential plates or blocks A are formed with
tongues and grooves b extending for a greater part of their length as shewn in
Figure 3 and the ends are formed with grooves as shewn in the section at Figure 4,
the end plates or blocks are formed as shewn at Figures 5, 6, and 7.
In order to construct a triturating cylinder of blocks or plates formed as above
described, I slide the tongue a of one block or plate into the groove b of the other I
then secure all the plates or blocks together lengthwise by inserting the keys C into
the slots formed by the grooves b¹ coming together as shewn in section Figures 1 and 9.
The end plates B are also held together by the tongue a on one plate or block fitting
into the groove bon the next. The plates or blocks are made of chilled cast iron or
such like material so as to form a hard and durable grinding surface. Triturating
cylinders constructed as above are applicable for either wet or dry grinding.
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. The employment of plates or blocks of chilled cast iron or such like material
substantially as set forth.
2. The method of securing the plates or blocks together substantially as set forth.
3. Constructing triturating cylinders substantially as set forth.
