MOSES LENZBERG and MICHAEL MEYER LENZBERG, trading as M. Lenzberg and
Son, of South Place, in the City of London, Manufacturers. IMPROVEMENTS IN
STAIR ROD EYES."
This Invention relates to improvements in the construction of the eyes employed
for receiving the rods for holding or fixing carpet on stairs or steps, the object of
the improvements being to allow of the "eyes" being adjusted to suit different
thicknesses of carpet.
>>
In carrying out the Invention that part of the "eye" which is fixed to the stair
or in the step is formed of the same shape as usual; but I form the "eye
properly so called separately and with a screwed projection which screws into a
tapped hole in the other or fixed part of the "eye." This construction allows of
the "eye" being adjusted to suit different thicknesses of carpet, and allows of the
rods being placed with great facility in position, and also allows of "eyes" of
different sizes being fitted in the fixed part or body of the device without the
necessity of removing such fixed parts, which is of great advantage in the case of
the "eyes" employed for stone staircases.
-
In a modification of the arrangement I adapt a suitable spring in the body or
fixed part of the "eye," which allows of the "eye" having a certain amount of
play, so that it will automatically adjust itself to suit the thickness of carpet,
without the necessity of unscrewing or turning the "eye" as in the arrangement
hereinbefore described.

In the latter arrangement the "eyes" are also fitted to the "body" by means of
a screw and nut, or other suitable arrangement, to allow of "

turn.

eye
"
In carrying out the Invention that part of the "eye" which is fixed to the stair
or in the step is formed of the same shape as usual; but we form the "
properly so called separately and with a screwed projection or shank, which screws
into a tapped hole in the angle of the other or fixed part of the "eye." This
construction allows of each pair of eyes being so adjusted as to carry a rod in a
position to suit different thicknesses of carpet, and also allows of ",
eyes" of
different sizes being fitted in the fixed part or body of the device, without the
necessity of removing such fixed parts, which is of great advantage in the case of
the "eyes" employed for stone staircases.
In a modification of the arrangement we adapt a suitable spring in the body or
fixed part of the "eye," which allows of the "eye" having a certain amount of
play, so that it will automatically adjust itself to suit the thickness of carpet,
without the necessity of unscrewing or turning the "eye," as in the arrangement
hereinbefore described.
In the latter arrangement the "eyes" are also fitted to the "body" by means of
a screw and nut, or other suitable arrangement to allow of "eyes" of different
sizes being fitted to the " body" without the necessity of removing the "body.".
It will be understood that when the rods are placed in position the " eyes"
cannot turn.
But to make our Invention better understood, we will proceed to describe the
same by reference to the accompanying Drawing in which Figure 1 is a side view,
Figure 2, a front view, and Figure 3, a perspective view of a stair rod eye suitable
for wooden stairs constructed according to our Invention; Figure 4 is a perspective
view of an eye for stone staircases; Figure 5 is a sectional elevation of a spring
stair rod eye constructed according to our Invention, and Figures 6 and 7 represent
a plan and a front elevation respectively shewing our improvements applied to a
box stair rod eye.
Similar letters in all the Figures represent similar or corresponding parts.
In Figures 1, 2, and 3, a is the part of the eye forming a back plate which is
fixed to the stair in the usual manner by screws or pins through the holes b, b;
c is the eye properly so called, which is formed with a screwed projection or
shank d, which screws as shewn into a tapped hole in the angle of the back
plate a.
By this construction of stair rod eye it will be understood that by screwing the
eye c inwards or outwards, the distance of the eye from the angle of the stairs may
be diminished or increased, the amount of adjustment being limited by the length
of the screw shank d. This arrangement thus allows of each pair of eyes being so
adjusted as to carry a rod in a position to suit carpets of different thicknesses.
The stair rod eye shewn in Figure 4 is substantially the same as that shewn in
Figures 1, 2, and 3, except that the screwed shank of the eye c screws into a tapped
body or socket a adapted to be fixed in a stone step of a staircase or the like.

page_text: In Figure 5 the shank of the eye instead of screwing into the body or socket a,
as hereinbefore described, slides loosely therein, the eye c being screwed on the
upper end of the shank d which projects above the socket a; e is a spiral spring
which allows of the eye c having a certain amount of play, so that it will auto-
matically adapt itself to the thickness of the carpet, and the shank being in two
parts will allow of the eye being removed if required to substitute another of
different size.
Figures 6 and 7 represent a plan and a front elevation respectively shewing the
Invention applied to a box eye; in this arrangement a is the back plate which is
fixed obliquely, and in which slides the shank on which is screwed the box eye c.
The action is substantially the same as that described in reference to Figures 1 to 4,
except that the eye is adjusted by being moved up or down instead of screwing up
or down; the eye having been adjusted to the required height to suit the
thickness of the carpet is fixed in position by being screwed tightly against the
back plate a.
Having thus described the nature of the said Invention and the best means
with which we are acquainted for carrying the same into effect, we would have it
understood that we do not confine ourselves to the exact details herein laid down,
as the same may be varied without departing from the peculiar character of our
Invention, but what we do claim is,-
Firstly. The manufacture and use of adjustable stair rod eyes to suit carpets of
different thicknesses, as hereinbefore described.
Secondly. The construction and employment of the improved stair rod eyes,
arranged and operating substantially as herein before described and represented in
Figures 1 to 4 of the accompanying Drawing.
Thirdly. The construction and employment of the spring stair rod eye, as
herein before described and represented in Figure 5 of the accompanying Drawing.
Fourthly. The improved box eye, constructed, arranged, and operating sub-
stantially as hereinbefore described and represented in Figures 6 and 7 of the
accompanying Drawing..
In witness whereof, we, the said Moses Lenzberg and Michael Meyer Lenzberg,
have hereto set our hands and seals, this Twenty second day of July, in the
year of our Lord One thousand eight hundred and eighty one.
