J, MICHAEL JOSEPH RYAN, of 2, Seymour Road, Litherland, in the County of
Lancaster, Purser, do hereby declare the nature of this invention to be as
follows:-
The invention the subject of this application, has reference to means for holding
doors in the required positions, and has, mainly, for its object, amongst other
things, to provide improvements in door holders, or an improved door holder, by
which doors liable to swing about when open, can be automatically held in any
position. For instance, it is very suitable for use in connection with ships' state-
room or cabin doors, for which it was primarily designed.
According to this invention, there is provided on the door frame a hinged bar
capable of moving about its hinge in the horizontal plane, and also, in some cases,
in the vertical plane; while on the door, there is a guide or eye, through, or in
connection with which the bar works, and adapted to press upon the bar (preferably
as hereafter described) by which, while the door may be moved by pressure, in either
direction, it will be held by this device or apparatus when free.
According to one form, the eye or guide referred to is mounted in a socket or
holder (say of tubular form) in which it is free to rotate; while up through
the eye support or guide, that is, the part which works in the socket or holder, there
is a bolt, catch, or the like, which is normally pressed up by a spring within the
socket or holder, on to the under edge of the hinged bar; and this hinge bar being
provided with grooves, serrations, or the like, with which the bolt or catch engages;
and when so engaged, will hold the bar, and prevent the door swinging backwards or
forwards by the movement of the ship, or like causes; while at the same time, by
pressing the door in either direction, it can be opened further, or moved towards the
door frame. Thus, the door is prevented from slamming and banging about, and
becoming damaged, and all annoyances from such causes are obviated.
Two parts on the frame of the door can be arranged as described, or their converse
arrangement employed; whilst the constructions and forms of the parts may be
modified variously without departing from the invention.

I, MICHAEL JOSEPH RYAN, of 2, Seymour Road, Litherland, in the County of
Lancaster, Purser, 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 :-
The invention the subject of this application, has reference to means for holding
doors in the required positions, and has, mainly, for its object, amongst other things,
to provide improvements in door holders, or an improved door holder, by which
doors liable to swing about when open, can be automatically held in any position.
For instance, it is very suitable for use in connection with ships' stateroom or cabin
doors, for which it was primarily designed.
According to this invention, there is provided on the door frame a hinged bar
capable of moving about its hinge in the horizontal plane, and also, in some cases; in
the vertical plane; while on the door, there is a guide or eye, through, or in connec-
tion with which the bar works, and adapted to press upon the bar (preferably as
hereafter described) by which, while the door may be moved by pressure, in either
direction, it will be held by this device or apparatus when free.
According to one form, the eye or guide referred to is mounted in a socket or
holder (say of tubular form) in which it is free to rotate; while up through the eye
support or guide, that is, the part which works in the socket or holder, there is a bolt,
catch, or the like, which is normally pressed up by a spring within the socket or
holder, onto the under edge of the hinged bar, and this hinge bar being provided
with grooves, serrations, or the like, with which the bolt or catch engages, and when
so engaged, will hold the bar, and prevent the door swinging backwards or forwards by
the movement of the ship, or like causes; while at the same time, by pressing the
door in either direction, it can be opened further, or moved towards the door frame.
Thus, the door is prevented from slamming and banging about, and becoming
damaged, and all annoyances from such causes are obviated.
Two parts on the frame of the door can be arranged as described, or their converse
arrangement employed; whilst the constructions and forms of the parts may be
modified variously without departing from the invention.
The invention is illustrated in the accompanying drawings. In these, Figure 1 is
a plan, and Figure 2 a front elevation, partly in section, shewing one form or arrange-
ment of my automatic holder. Figure 3 is an elevation, partly in section, shewing a
modification; and Figure 4 is an elevation shewing a further modification, being a
converse arrangement of that shewn in Figures 1 and 2.
The same letters and figures of reference are used to denote the same or equivalent
parts whenever they occur in the different figures.
Referring to the drawings, and mainly to Figures 1 and 2, a is the hinged bar,
mounted on the door frame b by a duplex joint a¹ a¹, giving it motion in any direction
required about this joint; and a2 are conical or tapered recesses or notches in the
underside of this bar. c is the guide eye through which the bar a passes, this eye
being carried and supported in a socket tube d, carried and fixed on the door frame e,
by a bracket d. The guide eye c is free to revolve in the tubular socket d; and
through the base portion a conical or hinged headed bolt or pin ƒ passes, this bolt
being normally pressed upwards by a spring h, acting upon the enlarged head f¹ of ƒ.
"The guide eye c has a flange or ledge cl-at its lower end; and the socket has an
internal flange 62 at its upper end, against which the upper shoulder of c¹ rests. The
guide eye c, bolt f, and spring h, are introduced into the socket tube d from the
lower end, the lower end of which is closed by a screw plug i; and both the guide
and bolt being normally pressed up by a spring h.

page_text: In action, as the door is opened or closed, the bar a will pass through the guide
eye c; the normal position of the head of the pin or bolt f being within one of the
recesses ²; and when the door is moved, the movement of the bar presses the bolt f
by the conical or inclined sides of the recesses a², out of the recess against the action
of the spring d, and so disengages or frees the catch or holder. When the door has
been moved to the point required, it is so moved and left that one of the recesses a²
will be over the bolt f; and the spring pressing this bolt up, forces it into this recess
a², and engagement with the bar automatically, and holds it there. The recesses a²
being tapered or inclined, the engagement of the bolt with the bar a, is firm, and
without "lash" or play; and hence there is no rattle or noise between the parts.
Of course in the opening or closing of the door, the angle of the bar a in relation
to the plane of the door frame changes, and so moves the rotatable guide c about its
axis, as it passes through it in either direction.
The modification shewn in Figure 3 is more suitable as an automatic holder for
doors mounted and working in the manner of casement or French windows, or for
such windows themselves.
In this case the tubular socket , is sunk into the sill et of the frame of the door
or window; and the bar a will be secured similarly as that shewn in Figures 1 and 2
to the window frame. In other respects, its construction is the same as that shewn
in Figures 1 and 2; and its action is identical.
In the converse arrangement shewn in Figure 4, the bar a is supported and hinged
upon the frame e of the door way; while the tubular socket d is fastened by a flange
on to the upper part of the door. In other respects than this, this modification is
also similar in construction to that shewn in Figures 1 and 2; and is identical in
action.
The above constructions and arrangements suffice to make clear the nature and
characteristics of my invention; but it is in no way restricted to these special
constructions, as it may be modified as to form and arrangement in many ways to
meet special cases or requirements.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
.1. An automatic holder for doors, or the like, comprising a bar with recesses or
equivalent provisions, and a movable or rotative guide eye and bolt passing and
pressed up through the said eye, and adapted to engage with the bar; substantially
as and for the purposes set forth.
2. An automatic door or like holder, comprising the hinged bar a having recesses
a', a socket d carrying the eye c and bolt f within it, the said bolt being normally
pressed upwards through the eye, and towards the underside of the bar; substantially
as set forth with reference to and shewn in the drawings.
3. The automatic door or like holders, particularly as shewn in and set forth with
reference to Figures 1 and 2, Figure 3, and Figure 4 of the drawings, respectively.
