PROVISIONAL SPECIFICATION.
An Improvement in or Connected with the Bottom and Elbow Plates
of Rag Engines.
I JAMES BRAILSFORD Machine Knife Manager to Messrs. Colver Brothers of the
Pilot Works Sheffield in the County of York do hereby declare the nature of this
invention to be as follows:-
The Invention relates to and consists in the construction and use of an improved
and more readily efficient divider to be applied to and employed in the bottom and
elbow plates of rag engines.
My improved divider, which is composed either of steel or of iron, is made easily
movable so that the bottom or elbow plate, or the bars of the plate, can be regulated
without being taken out of the box containing same; each divider is made with a
sufficient number of slots in it so that it can be moved either up or down in order to
regulate or adjust the cut of the plate; the bars of the plate are made with round
holes therein through which and through the slots in the dividers round bolts are
passed having fastening nuts thereon so as to secure the whole together.
By loosening the nuts the dividers can be readily lowered as the bars of the plates
wear down.
These dividers can be made of any thickness or size so as to be readily worked in
bottom and elbow plates of any dimensions.

An Improvement in or Connected with the Bottom and Elbow Plates
of Rag Engines.
I JAMES BRAILSFORD Machine Knife Manager to Messrs. Colver Brothers of the
Pilot Works Sheffield in the County of York 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, in writing, and on
reference to the accompanying sheet of drawings :-
This Invention relates to and consists in the construction and use of an improved
and more readily efficient divider to be applied to and employed in the bottom and
elbow plates of rag engines, which divider is slotted, and it is made either of steel or
of iron, or it may be made of any other suitable material.
In order that my invention and the carrying it out in practice may be fully
understood, it is illustrated on the accompanying sheet of explanatory drawings,
on which Figure 1, represents an elevation of a rag engine bottom elbow plate with
movable dividers, all put together and as fixed ready for use.
Figure 2, is an end elevation of the same.
Figure 3, is an elevation of one of my slotted dividers put together in sections
or parts.
Figure 4, is an elevation of a slotted divider made all in one piece. And,
Figure 5, is an end elevation of a rag engine plate having slotted dividers in it
made all in one piece.
The same letters of reference corresponding with the following description indicate
like parts in all the Figures.
My improved slotted divider a, which is the most distinctly shown in Figures 3,
and 4, is made so as to be easily movable in order that the bottom or elbow plate b,
(Figures 1, 2, and 5,) or the bars of the plate, can be regulated without having to be
taken out of the usual box containing the same. Each divider a, is made with a
sufficient number of slots in it, such as shown in Figures 3, and 4, so that the
divider can be moved either up or down in order to regulate or adjust the cut
of the plate.
These slotted dividers, when it becomes necessary for the purpose of giving
additional width thereto, are made sectional, that is, in two parts or sections, -as
shown at d, in Figure 3; or they can be made in more parts or sections if required.
The sectional part d, is dovetailed into, or fixed to, the lower part of the divider as
at e; or it can be similarly fixed to the upper part of the divider if required.
The bars of the plate are made with round holes therein, such as those at f, in
Figure 1, through which and the slots c, în the dividers a, round bolts g, are passed
which have fastening nuts h, screwed thereon so as to secure the whole together and
keep the same firm. By loosening the nuts h, the slotted dividers a, can very readily
be lowered or moved as required according as the bars of the plates wear down.

page_text: My slotted dividers can be made of any desired strength, or thickness, or size, so
as to be readily inserted and worked in bottom or elbow plates of any dimensions.
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 :-
The construction and the application to and employment in or connected with the
bottom or elbow plates of rag engines, of improved and easily movable slotted
dividers, each divider being made either in one piece, or in two, or more, sections or
parts, substantially as hereinbefore described, and as illustrated on the accompanying
drawing.
Dated this 25th day of May 1888.
