AN IMPROVED METHOD OF KEEPING ORDINARY WOODEN OR OTHER LIKE WEDGES OR KEYS FOR RAILWAY CHAIRS IN' POSITION
Year: 1885

page_text: I GEORGE HOPKIN WELLS of 48, Monmouth Street Sheffield in the County of
York Coach Smith do hereby declare the nature of my invention for "AN
IMPROVED METHOD OF KEEPING ORDINARY WOODEN OR OTHER LIKE WEDGES OR
KEYS FOR RAILWAY CHAIRS IN' POSITION " 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 and claims to be an improved and simple method of
keeping ordinary wooden or other like Wedges or Keys for Railway Chairs in
position, instead of such Wedges or Keys having to be constantly struck back into
position, as at present, and whereby also, the permanent support of the Chair is
increased.
To effect my object, I employ a kind of Cramp as follows namely:-I insert between
the bottom part of the Wedge and the Chair on the left hand side, a small finely
shaped iron wedge, which can easily be struck into its place, and on the outer side
of this Wedge, the same extends and finishes in a Catch or Hook-To this outer
side, a small iron Rod is then connected or attached, which extends over the back
part of the Chair, and then turns inwards opposite the face of the other side of
the wooden or other Wedge.
At the point in such Arm opposite the Wedge, a screw hole is drilled, into which
a Screw with head thereto, is inserted, and by screwing up against the Wedge, the
same is held firmly in position.
At the point of the small iron Rod which comes in contact with the small iron
Wedge, is a slot or opening, which fits upon the Hook, and when the screw is then
applied, all the parts are drawn together, acting as a Cramp, whereby the Wedge
is by the screw end, pressed and kept back to the left as required.
For the event of loosening, arising from the shrinking of the Wedge, from
variation in atmosphere or otherwise, the Screw can easily be tightened up again,
and the parts are also easily removable on the Wedge having, for any purpose, to
be removed. I prefer to make the parts of my Invention of iron, but the same
may be made of any hard material, and I do not confine myself to the quality or
character of the material, nor to the thickness or length of the parts employed.
The accompanying Drawings illustrate the features of my Invention.
Figure 1. shews the small iron Wedge referred to.
Figure 2. shews the small iron Bod referred to with the Screw in some

page_text: Figure 3 shews the outline of an ordinary Rail and Chair and Wedge, with the
application of present Invention thereto.
Like letters of reference where such letters appear indicate corresponding parts
in the Drawings.
In Figure 1A is the part to be inserted between the lower part of the Wedge,
and the Chair, and B is the Hook which receives the slot or opening of the Arm-
In Figure 2 the Arm C has the opening or slot at D, which receives the Hook
referred to, and E is the Screw which tightens up directly against the Wooden or
other Wedge.
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
In connection with ordinary Wooden or other like Wedges or Keys used with
Chairs on Railways, an improved and simple method for keeping such Wedges or
Keys in position, by the application of a small iron Wedge, iron Rod, and Screw,
acting as a Cramp as above described.
