A New or Improved Railway Chair and Key or Wedge.
We, JOE ORCHARD, of Millhouse, Eastleigh, in the County of Hants, Timber
Merchant's Assistant, and JAMES NUTBEEM, Junior, of Barton Mill, Eastleigh, in the
county aforesaid, Miller, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to Railway chairs and Keys or wedges.
The main object of our said invention is to provide Railway Chairs and Keys of
improved form, whereby the Keys are not so liable to become disengaged from the
chairs, as is the case with those now ordinarily made.
In Railway chairs now ordinarily made and fitted, the inside face of same-that
is the part facing the outside of rail-is made and arranged so that the said face
lengthways of the rail is parallel to the rail, the Key or wedge being also made with
parallel sides or nearly so. Thus it is necessary to provide Keys of very exact
thickness for use with chairs so formed for if too thick they cannot be entered readily
between the chair and rail, and if not thick enough they do not do their work
effectively of binding the rail and chair together. According to our invention we make
our improved chairs with tapered face, lengthways of the rail, and supply
correspondingly tapered wedges or keys, thus the latter can be easily entered between
the chair and rail-at the wide end of the former,-and set up to any desired extent
thereby firmly securing the rail to the chair.
To prevent the wedge slipping back after being set up we provide that the face of
the chair shall be suitably roughed in one direction, lengthways of the rail, so that
the wedge can be easily driven home, but the roughing will prevent, or at least to a
great extent serve to prevent the wedge slipping back, that is its disengagement
from the driven home position-when shaken by the passage of trains over the
chair.

I, JOE ORCHARD, of Millhouse, Eastleigh, in the County of Hants, Timber Merchants
Assistant, and JAMES NUTBEEM, Junior, of Barton Mill, Eastleigh, in the county
aforesaid, do hereby declare the nature of this invention and in what manner the
[Price 8d.1

the following statement:-
Our invention relates to Railway Chairs and Keys or wedges.
The main object of our said invention is to provide Railway chairs and Keys of
improved form whereby the keys are not so liable to become disengaged from the
chair as in the case with those now ordinarily made.
In the accompanying drawings we have shewn what we consider to be the best
means of carrying out our invention, in which :-
:-

Fig. 1 is an elevation partly in section shewing a chair and wedge constructed
according to our invention.
Fig. 2 a plan on top of Fig. 1.
Fig. 3 an elevation partly in section taken on the line a. a.
Like letters indicate corresponding parts in the different views.
In railway chairs now ordinarily made and fitted the face A of the chair is made and
arranged so that when the chair is in place the face will be parallel to the rail D,
lengthways of same, the key or wedge being also made with parallel sides or nearly
so, thus it is necessary to provide wedges of very exact thickness for use with chairs
so formed, for if too thick they cannot be entered readily between the chair and rail,
and if not thick enough they do not perform their work effectively of binding the rail
and chair together.
According to our invention we make our improved chairs B with a tapered face A,
lengthways of the rail, and supply correspondingly tapered wedges C for use with
same, thus the latter can be easily entered between the chair and rail at the wide
end E of the former and set up to any desired extent, thereby firmly securing the
rail to the chair.
To prevent the wedge slipping back after being set up we provide that the face A
of the chair shall be suitably roughed as shewn, in the direction lengthways of the
rail, so that the wedge can be easily driven home, the roughing will prevent, or at
least serve to prevent to a great extent, the wedge from slipping back, that is its
disengagement from the driven home position when shaken by the passage of trains
over the chair.
Having now fully described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1st. Improved railway chairs, with a tapered and roughed entrance for the
wedge, in combination with a tapered wedge, as, and for the purpose hereinbefore
described.
2nd. The improved railway chair and wedge constructed and combined substantially
as described with reference to the accompanying drawings and operating as, and for
the purpose above specified.
