PROVISIONAL SPECIFICATION.
Improvements in Keys for Fastening and Retaining in Position
Railway and other Rails in their Chairs.
I, WILLIAM HENLEY, of 30 Camplin Street, New Cross, London, Metal
Plate Worker, do hereby declare the nature of this invention to be as follows:-
In making my improved key for the purposes of my invention, I provide a
wooden key through which is bored transversely a hole; in the hole is placed a
more or less loosely fitting lug, pin or the like sufficiently long to pass through the
thickness of the key, to this lug, pin or the like is attached at right angle to it a
strip of metal or like having one end turned out over at a right angle to the strip
and away from the key. In use I place the above mentioned lug in the hole in
the keys and drive in the key together with the lug and strip until the turned out
end of the strip touches or clips one end of the rail chair, and I then turn out the
other end of the strip so that it touches or clips the opposite end of the rail-chair.
I make the above mentioned lug, pin or the like of sufficient length that supposing
the key to shrink, it will keep the rail at the same distance from the key as it
would have been had the key not shrunk ; and the turned out ends of the strip
being in contact with each side of the rail chair prevents the key from slipping
longitudinally, either by vibration of the passing vehicles or other causes.
practice I sometimes provide a groove in the outer face of the chair of the same
width as the strip attached to the lug or the like, and sufficiently deep that the
strip may rest therein with its outer face flush with the outer face of the key.
In
The lug or the like can be a separate piece attached to the strip of metal, or it
can be formed in one piece with the strip. The lug, pin or the like may be of
wood or other similar material with a otch at the outer end of it.
In this case the strip of metal touching or catching each end. of the rail-chair,
has a projection on it to enter the notch in the end of the lug.

Improvements in Keys for Fastening and Retaining in Position
Railway and other Rails in their Chairs.
I, WILLIAM HENLEY, of 30 Camplin Street, New Cross, London, S.E. Metal
Plate Worker 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 :-
For the purposes of my invention I employ as shewn in the accompanying
drawings the usual well known wooden railway chair keys. Through the key A is
bored, transversely, a hole, B, which receives a more or less loosely fitting lug, pin,

page_text: or the like, C, of sufficient length to pass through the thickness of the key A.
This pin, lug, or the like, is attached at right angles to, or it may be formed in
one with, a strip of metal or the like, D, having one end turned out at a right
angle as at D¹ to said metal or like strip, and away from the key. The manner of
using my improved chair fastening is as follows:-I place the lug C in the hole B
formed in the key, and drive in the key-between the jaw F of the chair and the
rail-together with the lug and strip until the turned out end of the latter, clips
one side of the chair; I then tuin out the other end of the strip D so that it clips
the opposite side of the chair as at D' as shewn in the sectional elevational view
Figure 1 and sectional plan view Figure 2. The above mentioned lug, pin or the
like C is made of sufficient length that supposing the usual wood key A to
shrink, the rail will be kept at the same distance from the chair as it would have
been had the key not shrunk and the turned out, and over, ends D', D' of D being
(when the compound key device is "in situ") in contact with each side of the rail
chair, prevent the key from slipping longitudinally, either from vibration of the
passing trains or from other causes; as the lug C is kept in position central with
the chair and rail. I provide, as will be seen more particularly on reference to the
detached views Figures 3 and 4, a groove, slot or recess E, along the face of the
key A, sufficiently deep that the strip D may rest in E, with its outer face "flush"
with the outer face of the key A.
As herein before stated the lug or the like, C may be either formed in one with
the strip D (Figure 5 being a detached side elevational view of the strip and lug)
or it might be (that is, the lug,) a separate member attached to D; under this
latter arrangement, the lug C might be made of wood or like substance—the grain
of the wood being "end on
" towards the face of the rail-and, in such case, the
lug C would have a notch across its outer end and the clipping strip D would be
formed with a projection on it to enter the notch in end of C.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I wish it to be
understood that I make no claim in respect per se of a clipping strip such as herein
described but what I claim, is.
For retaining in position the keys of rail chairs the employment of the pin, lug,
or the like such as C herein described in connection with a clipping strip; said
pin, lug or the like serving as an abutment to prevent the full pressure of the
passing traffic on the rail being communicated to and received by the wooden key.
Dated this 13th day of May 1896.
