Improvements in or relating to Appliances for Closing Doors and
the like.
We, LA SOCIÉTÉ MINIER AND PORTELANCE of 16, Rue Drouot, Paris, in the
Republic of France, Manufacturers do hereby declare the nature of this invention
to be as follows:-
The object of this invention is an improved combination for a door closing
appliance, consisting of a spring drum and draw bar, to allow of easy stoppage,
regulation and disengagement.
'
This door closer, which has every desirable quality, such as solidity, elegance
and good action, possesses the advantage of closing the door gently and that it can
be regulated as required.
The system of winding up the drum is such that it can be so arranged that the
axle carrying the spring only makes a certain given number of turns; if the tension
obtained be too strong it will be sufficient to release the stop catch of the drum,
taking care to hold the key firm, which allows the spring to be released to the
desired point. In order to throw the door closer out of action, the part serving as
draw bar need only be raised and allowed to rest on its bracket.
The drum of the appliance having an internal spring is fixed on the frame of
the door and contains, wound up, a spring; this acts on a gripping-piece, hinged on
the draw bar which is of the shape of an H, so as to easily engage in a bracket
fixed on the door.
The system of winding up comprises a checking device, limiting the number of
turns which the axle of the drum shall make; this checking device is formed of a
disc in which a cog is cut out, and on which a peg, fixed on the axle of the drum,
presses. It is self evident that, at each turn, the peg will cause the disc to advance
one notch, until it strikes against the plain periphery of this disc; but, as there
are only two detents, the axle can only make two turns, which, however, suffice for
giving sufficient tension.
If the tension obtained be too strong, it can be diminished as may be required by
releasing the pawl which, for this purpose, has an extension in order to be more
easily handled, during this operation it is indispensable to hold a key fitting on top
of the axle firm in the hand in order to avoid a sudden and complete release of the
spring.
If it be desired to throw the door closing device out of gear, it suffices to
disengage the draw bar from its seat in the bracket and allow it to rest against
the drum.
This apparatus can be affixed to any door, owing to its ease of working either
right or left.
The form, materials and dimensions of the above door closer, as well as the
rrangements of its component parts, can be varied.

Improvements in or relating to Appliances for Closing Doors and
the like.
We, LA SOCIÉTÉ MINIER AND PORTELANCE of 16 Rue Drouot, Paris in the
Republic of France, Manufacturers 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 object of this invention is an improved combination for a door closing
appliance, consisting of a spring drum and draw bar, to allow of easy stoppage,
regulation and disengagement.
This door closer, which has every desirable quality, such as solidity, elegance
and good action, possesses the advantage of closing the door gently and that it can
be regulated as required.
The system of winding up the drum is such that it can be so arranged that the
axle carrying the spring only makes a certain given number of turns; if the tension
obtained be too strong it will be sufficient to release the stop catch of the drum,
taking care to hold the key firm, which allows the spring to be released to the
desired point. In order to throw the door closer out of action, the part serving as
draw bar need only be raised and allowed to rest on its bracket. In order that the
invention may be fully understood a sheet of drawings is annexed hereto, in which,
Figure 1 is an elevation of the appliance fitted on to a door, and
Figure 2 a plan view of same.
The drum a of the appliance having an internal spring a¹ is fixed on the frame C
of the door and contains, wound up, a spring ; this acts on a gripping-piece d,
hinged on the draw bar c, which is of the shape of an H, so as to easily engage in
a bracket fixed on the door P.
The system of winding up comprises a checking device, limiting the number of
turns which the axle of the drum shall make; this checking device is formed of a
disc in which a cog is cut out, and on which a peg h fixed on the axle i of the
drum a presses.
It is self evident that, at each turn, the peg / will cause the
disc g to advance one notch, until it strikes against the plain periphery of this
disc; but, as there are only two detents, the axle i can only make two turns, which,
however, suffice for giving sufficient tension.
If the tension obtained be too strong, it can be diminished as may be required
by releasing the pawl which, for this purpose, has an extension in order to be
more easily handled, during this operation it is indispensable to hold a key / fitting
on top of the axle firm in the hand in order to avoid a sudden and complete release
of the spring.
If it be desired to throw the door closing device out of gear, it suffices to
disengage the draw bar c from its seat in the bracket and allow it that is to say
its gripping piece d (connected with the spring b) to rest loosely against the drum
as shown in dotted lines in Figure 2.
This apparatus can be affixed to any door, owing to its ease of working either
right or left.
The form, materials and dimensions of the above door closer, as well as the
arrangements of its component parts, can be varied.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In an appliance, of the kind hereinbefore described and shown, for closing
doors and the like, the employment of a spring drum and draw bar, substantially
in the manner and for the purposes hereinbefore described.

page_text: 2. The general arrangement and construction of parts forming our improved
appliance for closing doors and the like, substantially as hereinbefore described and
shown.
