page_text: I, EDWARD JOHN HORSLEY, of Elworth, Sandbach, in the County of Chester,
Engineer do hereby declare the nature of this invention to be as follows:-
The application of sliding plates A, A, which are forced by the pressure of the
steam, water, or air, (as the case may be) (which pass through the perforations B, B,
in piston block and june ring) along the block C, and which in their turn force the
piston rings D, D, up the inclined planes of the centre piece E, thus entirely doing
away with the necessity for any internal springs. The plates A, A, being operated on
by the pressure of steam water, or air (as the case may be) in the cylinder, must
necessarily work alternately, so bringing only one ring in action at once, thus doing
away with a great amount of friction. Not only is the friction of the ring not in work
done away with, but the friction of the ring in work is reduced immediately the cut
off takes place, and keeps on reducing in proportion as the steam, or air pressure is
reduced by expansion.

page_text: I, EDWARD JOHN HORSLEY, of Elworth, Sandbach, in the county of Chester,
Engineer 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:―
The letters in this description refer to the drawing left with the provisional
specification.
The application of sliding plates A. A which are forced by the pressure of the steam,
water or air, as the case may be (which pass thro' the perforations B, B, in piston
block and june ring) along the block C, and which in their turn. force the piston
rings D, D, up the inclined planes of the centre piece E, thus entirely doing away
with the necessity for any internal springs. The plates A, A being operated on by the
pressure of the steam, water or air (as the case may be) in the cylinder, must
necessarily work alternately so bringing only one ring in action at once, thus doing
away with a great amount of friction. Not only is the friction of the ring not in work
done away with, but the friction of the ring in work is reduced immediately the cut
off takes place, and keeps on reducing in proportion as the steam or air pressure is
reduced by expansion.
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 utilisation of the pressure by the application of sliding plates, which being
acted on by the pressure in the cylinder in their turn force the piston rings up the
inclined planes of the centre piece, as described above, and as shewn on drawing left
with the provisional specification.
2. The application of a solid centre-piece which is so arranged us to completely
separate the two rings, so that the pressure nets on them alternately.
3. 2. The application of inclined planes on the centre piece, which cause the rings to
expand equally all round, and maintain a true circle.
4. 3. The combination of the above as described in my specification, and which
constitutes my invention.
