COMPLETE SPECIFICATION.
Piston Ring Pliers.
We, EDMUND JAMES DAVIS, of 32 Queen's Head Lane, Handsworth,
Mechanical Engineer, and SAMUEL WARD, of 36 Church Lane, Smethwick,
Engine Fitter, both in the County of Staffordshire, 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:-
Our invention relates to improvements in piston ring pliers.
The invention consists of a pair of pliers, made of steel or other metals, at the
gripping ends of which are two reversed mouths or jaws. These mouths or jaws
hold the ends of the ring in position while the piston ring is being expanded
sufficiently to clear the piston.
We attain this object by the mechanism illustrated in the accompanying drawing,
in which :-
Fig. 1 is an elevation of the pliers fitted to the piston ring situated round the
piston;
Figs. 2, and 3, are alternate mouths or jaws. These figs. are broken off for
convenience.
Similar letters refer to similar parts throughout the several views.
We construct a pair of pliers à made of steel or of any other metal, and at the
gripping ends of which are two reversed mouths or jaws c of various shapes as in
Figs. 1, 2, and 3. These mouths or jaws c hold the ends of the piston ring 6 to
expand the ring b sufficiently to clear the piston a.
If preferable the reversed mouths or jaws c may be made of any suitable shape
provided the pliers are used for the removal of the rings off a piston.
The object of our invention is its adaptability to any solid piston where the
rings are sprung on; the outer jaws being made as thin as possible which grips
the ends of the piston ring for expansion.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim, is-
1. In piston ring pliers, the combination of the pliers and the reversed mouths or
jaws e to hold the ends of the piston ring and expand the same sufficiently to clear
the piston, substantially as herein described.

page_text: 2. In piston ring pliers, the combination of the reversed mouths or jaws c,
substantially as herein described and according to the accompanying drawing.
3. In piston ring pliers, the combination of any suitable shape reversed mouths
or jaws to remove rings from pistons, substantially as herein described.
Dated this 14th day of January 1893.
