Improvements in Door and like Hooks.
I, DANIEL TAYLOR, of The Atlantic, Brunswick Street, Liverpool, in the County
of Lancaster, Engineer do hereby declare the nature of this Invention to be
as follows:
This Invention has reference to door-hanks used for holding doors in the open
or other desired position, the hanks being of the kind which are loosely hinged or
carried at one end, and have at their other end, a hook, which passes through an
eye on the door; or, vice versa. The Invention, however, is also applicable to
hanks used for similar purposes, as window hanks.
According to this Invention, the metal eye in which the hank hook passes is
provided internally with a lining of india-rubber, cork, leather, wood, or other
suitable yielding material, of a diameter corresponding with the diameter of the
body of the hank hook, so that when the hook is placed in position in the eye in
fastening the door, it bears upon the material in the eye, so that there is no play;
and at the same time, while this firm holding effect is obtained, the hook is readily
withdrawn from the eye, and the liability of jambing or sticking, as would happen
if a metallic contact were made, is obviated."
By this means, the rattling, which takes place with the ordinary hank fastening,
in ships' doors, and other similar doors, and the like, and its consequent annoyance,
is obviated.
In one case, the eye, which is made of metal, is hollowed out into an annular
recess round the aperture through which the hank hook passes; and into this
recess a rubber, cork, leather, wood, or like ring, is introduced; while in another
case, the ring passes through the metal eye.
As a modification of the above construction, I use a metallic eye, and employ on
the bank hook a covering of rubber, cork, wood, leather, or the like, preferably
slightly tapered on the outside, and suitably held by a recess, or other suitable
means, on the hank hook.
In action, of course, in this case, the effect is similar to that formerly described,
the construction being the converse of the former.

in and by the following statement:-
This Invention has reference to door-hanks used for holding doors in the open
or other desired position, the hanks being of the kind which are loosely hinged or
carried at the end, and have at their other end, a hook, which passes through an
eye on the door; or, vice versa. The invention, however, is also applicable to
hanks used for similar purposes, as window hanks.
According to this invention, the metal eye in which the hank hook passes is
provided internally with a lining of india-rubber, cork, leather, wood, or other
suitable yielding material of a diameter corresponding with the diameter of the
body of the hank hook, so that when the hook is placed in position in the eye in
fastening the door, it bears upon the material in the eye, so that there is no play;
and at the same time, while this firm holding effect is obtained, the hook is readily
withdrawn from the eye, and the liability of jambing or sticking, as would happen
if a metallic contact were made, is obviated."
By this means, the rattling, which takes place when the ordinary hank
fastening, in ships' doors, and other similar doors, and the like, and its consequent
annoyance, is obviated.
In one case, the eye, which is made of metal, is hollowed out into an annular
recess round the aperture through which the hank hook passes, and into this recess
a rubber, cork, leather, wood, or like ring, is introduced; while in another case,
the ring passes through the metal eye.
As a modification of the above construction, I use a metallic eye, and employ
on the hank hook a covering of rubber, cork, wood, leather, or the like, preferably
slightly tapered on the outside, and suitably held by a recess, or suitable means,
on the hank hook.
In action, of course, in this case, the effect is similar to that formerly described,
the construction being the converse of the former.
In the accompanying drawings, modifications according to the invention are
illustrated. In these, Figure 1 is an elevation partly in section shewing one form
of hank; and Figure 1 is a modification of this form. Figures 2 and 3 are two
alternative modifications connected with the hook. And Figure 4 is a modifica-
tion shewing the invention applied to the cheaper and commoner kind of door
hanks.
"
Referring in the first instance to Figure 1, the construction there shewn illus-
trates the invention as applied to a door or the like, of what would be called a
small" or "medium" sized hank; and of a type commonly used on board ship
for holding doors in their open position. The hank proper consists of a hook
portion a with a shank b, hinged at 1 to a joint piece c; which in turn is hinged
to the fastening jaw or eye d, screwed or equivalently fastened to a flange in the
ordinary way, to the door, or the stationary part. The two joints, give this hook
a movement both in the horizontal and the vertical planes. The hank eye, with
which the hook engages is designated i; and in the case shewn, is cored or bored
out where the hook passes through into a chamber, which is lined with a ring of
India rubber k, or other suitable material such as referred to, a cap 7, fastened by
screws or rivets, being provided on the bottom, which keeps the ring in place.
The chief object, however, of this cap or plate is to enable the chamber in which
the ring sits, to be bored or cleaned out after casting. It will be seen by the
drawing, that the hole in the upper part of the eye, and the hole in the plate 1,
are larger than the bore of the rubber ring, and the diameter of the hook a, so
that a clear inwardly projecting portion of rubber, within the metal, exists all
round, and prevents the hook coming up against the metal of the eye.
through the rubber or lining should be slightly less than or equal to the part
of the hook a which would normally rest within it, so that it practically touches
all round, and no movement between the hook or eye can take place; while at the
same time, one of these two parts being of comparatively soft material, the hook
Lan readily be placed in and taken out of the eye, and is not liable to stick.
The hole

position partly by adhesion, such as rubber solution, between its outside surface
and the metal round the hole in the eye; and partly by small flanges which fit.
or lap over the metal both at the top and bottom.
In the larger form of hanks of the type shewn in Figure 1, the chamber within
the eye may be cored out, that is, cast in, and is without the holding-in plate 7, it
being made both at the top and bottom, as the upper part of Figure 1.
Referring now to Figures 2 and 3; in these modifications, the hook portion a
of the hank is provided with a tubular ring of rubber or equivalent material over
the nose a¹ of the hook. In Figure 2 the nose portion a¹ of the hook a is recessed
annularly between the knob or end a² and its upper part; and in this recess the
tubular ring of rubber or other suitable material o is placed, it being sprung over
the tip a², and preferably also adhered to it by rubber solution, or other suitable
adhesive.
In Figure 3, the nose portion a¹ of the hook is reduced as shewn, and a tubular
ring cap o of rubber or other suitable material is passed or sprung over it; and
preferably adhered, by rubber solution or other adhesive, to the nose.
In these cases, the eye in which the hook fits will have its hole of a corre-
sponding size to suit the rubber or like parts o; in which cases, of course, no
lining in the eye is required.
Figure 4 shews a cheaper and commoner form of hank, in which the supporting
of the hank is effected by an ordinary eye ring d rivetted to or formed on, a sup-
porting plate, and an eye on the shank fitting over this eye ring; whilst the
hook a of the hank enters a similar fastening ring i on a simple plate. In this
case, the eye ring, will be lined at the parts where the hook will or might come
in contact with it, with rubber or equivalent material, this being equivalent to the
ring k shewn in Figures 1 and 1*. And at the supporting end of the hank, the
ring is surrounded with rubber d¹; or the eye of the hank may be so covered.
The hook a also, in some cases, may be of the kind shewn in Figures 2 and 3, the
rubber lining of which is carried up to such a height or degree that the one part
which comes in contact with the other will be lined with the covering material,
and so that no metallic connection or contact is made, and therefore, when the
hank shakes, no contact is made, and therefore, when the hank shakes, no objec-
tionable rattle or noise takes place.
Having now particularly described and ascertained the nature of this Invention
and in what manner the same is to be performed, I declare that what I
claim is:-
1. The improved door or other like hank in which, at the part where the hook
of the hank fastens or comes in contact with the eye, metallic connection between
the two parts is prevented by a non-metallic intercepting lining or covering on one
or other, or both of the parts, as described, and thereby providing a hank of the
kind referred to without rattle or noise; substantially as herein set forth, and as
shewn in the drawings.
2. The constructions of parts of door or other like hanks; particularly as shewn
in and set forth with reference to the drawings.
