Improvements in Stair Eyes.
I, CHARLES LAKEMAN TWEEDALE, Ravensleigh, Wigan Road, Ormskirk, Lan-
cashire, Clerk in Holy Orders, do hereby declare the nature of this invention
to be as follows:-
DESCRIPTION OF DRAWINGS.
Fig. 1 represents a side view of my improved stair eye.
Fig. 2 represents a side view of the same when in position and driven into the
stair.
Similar letters refer to similar parts.
My improved stair eye consists of a casting or forging in any suitable metal,
the lower part of which terminates in a spike A which is driven, or otherwise
fixed, into the stair when the eye is placed in position. This spike is made round
so that if the stair eye has to be set square with the front of the stair after being
driven into position, it does not loose its hold upon the wood, by being slightly
turned round.
At the top of the spike are two opposite projections K and N which serve to
regulate the depth to which the spike may be driven. The projection K also
serves to regulate the distance of the stair eye from the vertical face of the stair.
This projection K I call the distance stop.
The upper part of the casting or forging terminates in a suitable head B,
situated directly over the spike A and intended to receive the blows of the
hammer when driving in the stair eye.
The head B is extended on the same side as the projection K and forms a
hook H, which holds the stair rod down in it's required position. This nook I
call the rod hook.
The rod is inserted in the opening S (Fig. 2).
My improved stair eye can be adapted to hold round, square or triangular
stair rods without departing from the principle of the invention.
Suitable grooves can be cut round the spike A to increase it's hold upon the
wood, or it can be made in the form of a screw if required.
Dated this 31st day of January 1898.

Description of drawings, which are the same as those left with the, Provisional
Specification.
Fig. 1 represents a side view of my improved stair eye.
Fig. 2 represents a side view of the same when in position and driven into the
stair.
Similar letters refer to similar parts.

fixed into the stair when the eye is placed in position. This spike is made round
so that if the stair eye has to be set square with the front of the stair after being

The head B is extended on the same side as the projection K and forms a

Suitable grooves can be cut round the spike A to increase it's hold upon the
wood, or it can be made in the form of a screw if required.
Having now 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:-
-
The combination in a stair eye of a drive spike A, a drive head B, a distance
stop K, and a rod hook H, substantially as herin illustrated and described.
