COMPLETE SPECIFICATION.
Improvements in Door Fasteners, and in Apparatus for Operating
the same from a Distance.
We, JACOB BERNHEIMER KAUFMANN, and THEODOR MANGER KAUFMANN,
both of 4 Grüner Markt, Bamberg, Germany, 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 door fastening apparatus, and consists in an improved
lever and mode of attaching the same which permits of its being operated from
a distance.
It will be seen by the drawings that the whole apparatus is, in the case of a
single door attached to the frame or case, or in the case of a double or two-leaved
door to the fast leaf.
The apparatus is extremely simple in its construction consisting of a plate a,
with a pin b in the centre, upon which is pivoted and round which turns the lever
fastening c. The apparatus thus constructed is attached either to the door frame
or to a door, as hereinbefore mentioned, by means of screws d one or more of
which are arranged in such manner as not only to fasten the plate a to the
frame or door, but also to limit the movement of the lever c on its pivot, through
the required arc.
A hooked plate e is attached to the door frame or door in such manner as to
prevent the door being opened far enough to strain the pin b, to which the lever
is pivoted; and it can also be used to limit the movement of the lever c on its
pivot.
A cord g is attached to the lever c at or near the end c' and passes over pulleys,
eyes, or rings, to any desired part of the room or apartment; it terminates in a
tassel i, to which latter is attached a weight for the purpose of counter-balancing
the lever c.
If the tassel i be pulled down the lever c moves upwards, thus unfastening the
door which can then be opened. If on the other hand the tassel i be raised the
end of the lever c, drops downwards, and slips into the hooked plate e, thus
fastening the door and preventing accidental opening.
With a view to rendering it possible to fasten or unfasten the door from
another part of the room or apartment, branch cords g', are connected with the
main cord g and guided through rings or eyes to any desired position. If the
ring or tassel A be pulled, the door is thereby unfastened and can be opened; by
pulling the ring or tassel Z the door, if closed, is fastened.
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
claim is:
1. A door fastening apparatus consisting essentially of a movable lever fastening,
with a motion upon its pivot limited by stops, and a cord or cords attached to the
lever and passing through rings or other guides to another part of a room, where
it terminates in a weighted tassel, by means of which it is operated, substantially
as described and shewn.
2. In a door fastening apparatus, the combination of the plate a, the lever c

moving on a pivot b and having its movement limited by stops d, and e, the cord
the guides h, and the weighted tassel or equivalent device i, substantially as
.described and shewn.
