PROVISIONAL SPECIFICATION.
Improvements in Door-bolts.
I, JOSEF CATHREIN, of the Reform Hotel, Innsbruck, in the Empire of
Austria, Hotel-keeper, do hereby declare the nature of this invention to be as
follows:-
My invention relates to door-bolts and has for its object to enable a door to be
opened or closed by means of a cord from any point of the room.
In carrying my invention into practice I provide a casing in which is arranged a
bolt with a knob, the said bolt being adapted to move in a guide.
For displacing this bolt in one or the other direction I use, besides the said knob,
two cords which are fastened to a ring on the bolt.
One of the cords passes through an aperture in the casing, through a ring on the
casing, over a pin or roller and terminates in a tassel.
The second cord also passes through an aperture in the casing, through a ring ou
the casing, over a pin or roller and terminates in a tassel.
Both the tassels hang freely down a tablet placed at any point of the room
whence the door is to be either opened or closed.
The tablet bears the indication of the work to be done by means of each tassel.
If one of the tassels is pulled down the door is closed; and if the door is to be
opened the other tassel is pulled down, whereby the bolt is moved into the casing
and the door opened, the first tassel being then above.

COMPLETE SPECIFICATION.
Improvements in Door-bolts.
I, JOSEF CATHREIN, of the Reform Hotel, Innsbruck, in the Empire of
Austria, Hotel-keeper, 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 :-
My invention relates to door bolts and has for its object to enable a door to be
fastened or unfastened by means of a cord or the like from any part of the room.
In the accompanying drawing I have shown how my said invention can be
conveniently and advantageously carried into practice.
Figure 1 is an elevation of the bolt showing the cord connections and tablet.
Figure 2 is an horizontal section taken through the bolt and
Figure 3 is an end elevation of Figure 1.
In carrying my invention into practice I provide a casing A in which is arranged
a bolt B having a knob C, the said bolt B being adapted to move in a guide E.
For displacing this bolt B in one or the other direction I use, besides the said
knob C, two cords or the like a and b which are fastened to a ring c on the bolt.
The cord a passes from the ring c in the bolt through an aperture a¹ in the
casing, then through a ring A¹ on the said casing and over a pin cr roller a³ and
terminates in a tassel a³.
'
The cord passes through an aperture 6' in the casing, also through the ring on
the said casing A', over a pin or roller & and terminates in a tassel 63
The tassels a³ and hang freely down at a tablet T placed at any suitable point
of the room from whence the door is to be either fastened or unfastened.

page_text: The tablet T bears an indication of the operation to be performed by means of
each tassel in order to fastened or unfastened the door.
If, as represented in Figure 1 the tassel is pulled down the door will be
fastened; and if the door is to be opened the other tassel a is pulled down, whereby
the bolt B is moved into the casing A, and the door unfastened, the first tassel 6³
being then drawn up.
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 :-
A door bolt which is adapted to be unfastened or fastened by means of a cord
from any desired part of the room, comprising the bolt proper B with a knob C and
ring c to which the cords a and b are attached, substantially as described and
represented in the drawing.
