COMPLETE SPECIFICATION.
'Improvements in and connected with Stair Eyes.
I WILLIAM GATES. of No. 43 Dacre Road Upton Manor in the County of
Essex Carpet Salesman 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 :—
My invention consists of the improvements hereinafter described in and connected
with stair eyes the object of my said improvements being to facilitate temporary
removal of stair eyes from stairs.
According to my said invention I provide a small iron plate with bevilled sides
to be affixed on the rise of the stair case by two screws. And I provide a brass
stair eye with groove at back to fit on and cover iron plate and to be made
secure (if thought necessary) with screw pin at top which can be easily removed
for purpose of cleaning same.
My said invention is illustrated in the accompanying drawings Figure 1 of which
is a side view Figure 2 a back view and Figure 3 a section of a stair eye and a
holding plate formed and engaged together according to my invention the said
section Figure 3 being taken on the line 1 Figure 2.
In the following description of the said figures the parts thereof are referred to
by the letters marked thereon. The same letters of reference indicate the same
parts in all the said figures and in the other figures hereinafter referred to.
a is the stair eye and bis the holding plate on which the stair eye fits the said
eye having an undercut groove at back the sides of which engage with the bevilled
sides of the plate b (as clearly shown in Figures 1 and 3) when the eye is passed
laterally onto the said plate. c, e are holes in the said plate through which screws
for securing it to the rise of a stair are passed. dd are spikes formed on and
projecting from the plate b the object of which spikes is to admit of the said plate
being temporarily secured in the required position to the stair while the screws by
which the said plate is to be finally secured are being driven. e is the screw pin at
top of the eye a by which the said eye is secured to the holding plate 6. The said
screw e is engaged with a screw thread formed in a hole in the eye a and when
turned so as to cause the end of its shank to project from the back of the eye the
said screw engages in a depression in the holding plate whereby separation of
the eye from the said holding plate is prevented.
Figure 4 of the accompanying drawings is a side view and Figure 5 is a back
view of a stair eye and holding plate formed and connected together according to
my invention the holding plate and the groove in the eye being shown so formed

page_text: that the eye may be engaged with the holding plate by a longitudinal motion
instead of by a lateral motion as in the arrangement herein before described.
Figures 6 and 7 of the said drawings are sections taken respectively on the line 2
Figure 5 and the line 3 Figure 4.
As will be clearly seen by examination of Figures 6 and 7 the two longer sides
and the curved upper short side of the holding plate are bevilled and the groove in
the eye is so formed that the undercut sides of the said groove are parallel with
the upright sides of the eye.
When the groove in the eye and the holding plate are formed and engaged as
illustrated in Figures 1, 2 and 3 the screw e by which they are locked together
may be dispensed with as the pressure of the carpet rod due to tension of the
carpet cannot cause disengagement of the eye from the holding plate. The said
screw is however useful for preventing the eye from being accidentally shifted by
side blows which it is liable to receive when the stairs are being swept. Where
the longer sides of the holding plate are bevilled and the said plate is engaged
with the eye as illustrated in Figures 4, 5, 6 and 7 the locking screw e is necessary
for keeping the eye in place.
Where the eyes are intended for application to stone stairs dowels are required
on the holding plates in order that they may be fixed by means of lead in holes.
in the stairs as usual in the application of ordinary stair eyes, to stone stairs.
Figure 8 is a face view and Figure 9 is an edge view of a holding plate of the
form illustrated in Figures 4, 5, 6 and 7 and having a dowel formed on it for the
said purpose the dowel being marked in the said Figures 8 and 9. Where this
provision is required for securing the holding plate to a stair the screw holes c c
and the spikes d d are of course not needed.
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 I
claim :-
First: A stair eye and appliance for holding the eye to a stair formed and
'adapted for use substantially as hereinbefore described that is to say a stair eye
grooved at back and a plate adapted to be secured to a stair and so formed as to
admit of the eye being held in place as required by engagement of the grooved
part of the eye with the said plate.
Secondly-A stair eye and appliance for holding the same formed and adapted
for use substantially as hereinbefore described and provided with means for
admitting of the eye and holding appliance being locked together in the required
relative positions when engaged together substantially as herein before described.
