COME LEID DI BUITION
A Fastener for Keeping Doors, Windows, and the like in an Entirely
or Partially Open Position.
I FRANZ WEISS of 21 Graskeller, Hamburg, in the Empire of Germany, Engineer
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:-
This invention relates to the keeping of doors windows and the like in an entirely
or partially opened position and is especially intended for the doors used on ships as
a substitute for the hooks and eyes which were generally used beretofore for this
purpose.
The advantages of the new device over the aforesaid hooks are that the unpleasant
rattling which is caused by the hook during the motion of the ship is obviated and also
that the securing of the door takes place automatically upon the opening of the door
whilst in the other case the hook is to be inserted into the loop appertaining thereto
when the door is to be secured.
The invention is represented in the accompanying drawing in which
Fig. 1 is a sectional plan of a closed door."
Fig. 2 is a sectional plan of the door opened and fastened.
Figs. 3 and 4 are detail views of the fastener in elevation and plan respectively on a
larger scale.
Figs. 5 to 9 illustrate a modification of the fastener for securing doors or flaps
which are to be opened partially and kept in the respective position Fig. 5 being a
plan of a door when closed, said figure showing in dotted lines the secured door partly
and entirely open.
Fig. 6 is an elevation of part of the door quite open according
to Fig. 5. Figs. 7, 8 and 9 are respectively side elevation, end elevation in section
and plan on a larger scale of the fastener arranged according to Fig. 5.
Referring to Figs. 1 to 4 the device consists of the solid spring catch A arranged on
the door, the two outer spring arms e and e¹ of which catch encircle a part B fastened
to the wall or the object against which the door is to be kept. This part B is broadened
at the end m being suitably rounded so that the catches e and e' slide over the
broadened part when the door is pressed against the part B and encircle the same by
their inner surfaces as shown by Figs. 2 to 4. In order that the catches cannot be
bent, the stationary bar i is arranged between the same which touches against the
knob m as soon as the catch has encircled the latter. For the purpose of disengaging
the door from the fastened position shown in Fig. 2 a strong pull suffices to withdraw
the catches from the knob m.
The parts A and B may be exchanged also, so that B is arranged on the door, and A
on the wall.
If a door, a window or a hatchway is to be fastened in a partially opened position
which is frequently required on board ships, one uses besides the part B (which as
previously explained is to be arranged on the wall or some other stationary part of the
boat) also an arm D which is fastened to the door or window frame. Said arm is
shaped obliquely or bent and has a knob m' similar to the part B, which former
encounters the catch ee of the part A and as shown by Fig. 8 is shaped oval or round
in cross section so that the arms e e¹ which in this case are arranged double sided at
the part A as shown by Figs. 7 and 8 may be pressed from both sides upon the
knob m¹.
The remaining part of the arm D does not come into contact with the catch.
If the door, trap etc. is to be held partly open it is closed or opened so far until the
catches e e encircle the knob m' of the arm D as shown by Fig. 5 in dotted lines
(upper position) as seen by Figs. 5 to 9 the catch can be placed from either side over

page_text: the knob whereby the door passing the arm D can be closed or opened completely.
If the door is to be held quite open it is secured against the part B as previously
explained and as shown at the right hand side of Fig. 5 in dotted lines.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claiin is.
1. A fastener or holder for windows, doors or the like consisting of a part A which
carries in front the spring arms e e¹ and the stationary centre bar i in combination with
a second part B provided with a knob m which enters the arms when the said parts
are pressed together.
2. A fastener or holder for securing doors, windows or the like having the parts A
and B in combination with an arm D with projecting knob or equivalent m¹ in the path
of the catch whereby the catch can be passed from both sides over the knob or
equivalent m' or be secured thereby substantially as set forth.
