PROVISIONAL SPECIFICATION.
Improvements in Metal Fastenings for Wooden Bedsteads and other
Articles of Furniture.
We, PAUL KEUL, HENRI FERRAND, and LOUIS NUÉJOULS of 123 Rue due
Faubourg St. Antoine, Paris, Manufacturers, do hereby declare the nature of this
invention to be as follows:-
This invention consists of a system of external fastenings for holding together
the adjoining parts of wooden bedsteads, and other articles of furniture.
My improved fastenings may be constructed in either of the following ways.
1. I form two contiguous metal plates of any suitable shape, screwed or
otherwise attached to the wood, said plates carrying studs, or having their ends
turned up at right angles, and surmounted by flauges-said flanges being either
straight or curved.
The said studs or flanges engage with hooks, forks, or slotted plates which pass
over them and hold them together.
These said hooks, forks, or slotted plates may be caused to rise or fall on
separate studs or slots to which they are attached, or may be fitted in any other
suitable way.
2. I form two contiguous plates with studs or flanged ends as above, which
engage with a slotted plate, the slot of which has a contracted end or ends, said
worked by a
slotted plate rising and falling by means of an adjusting screw,
thumb bit or otherwise.
3. I form two contiguous plates as before described, on which are projecting
flanges, each engaging with a pirotted lever catch, both of which are operated
simultaneously by a tongue shaped plate, pressing open one end thereof.

COMPLETE SPECIFICATION.
Improvements in Metal Fastenings for Wooden Bedsteads and other
Articles of Furniture.
We, PAUL KEUL, HENRI FERRAND and LOUIS NUÉJOULS of 123, Rue due
Faubourg St. Antoine, Paris 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:-
Use has heretofore been made of bolts and nuts for connecting the various parts
of a bedstead. In order to place them, recesses have to be provided; the nut of
the bolt, let into the post of the bedstead necessitates difficult and very accurate
work in order to make it properly correspond with the bolt whose screw threaded
part passes through the recess and is screwed into this nut to effect the tightening.
Much time and trouble are required to put the bedstead together and take it to
pieces; the use of these bolts has other inconveniences which everyone in the trade
is aware of.
Other systems have been tried to replace these bolts, but none seems to be
adopted in practice.

page_text: Our invention obviates, the before-mentioned inconveniences. The bolts are
dispensed with and replaced by a system of iron fastenings having an automatic
tightening device and forming at the same time a ledge or angular bearing for
receiving the mattress.
The accompanying drawing represents full size three fastenings with a direct
tightening action.
Fig. 1 represents a type of fastening composed of three parts. A and B, are two
plates one of which is fixed to the foot of the bedstead and the other to the inner
side of the side bar of the bedstead frame, the two edges in front being bent as
shown in Fig. 1. The side bar is supported vertically by means of a loose
mortise joint with the foot. C is a square of flat metal bent at D and E. One of
the two bent parts, either D or E, is large enough to form a ledge upon which the
mattress of the bed rests. In the middle of the part C is an aperture F of special
form into which the bent edges of the plates A and B are passed. The upper
part of the aperture F is of such a contracted dimension and form that it constitutes
a tightening device at its upper part on the bent edges of the plates A and B,
whilst the lower part of the aperture is wider so as to enable the said plates
to be introduced. The weight of the mattress will thus be sufficient to effect the
tightening of the two plates A and B, and consequently to connect the two
parts of the bedstead without having recourse to screws or any other tightening
devices.
Fig. 2 represents a second type of fastening based upon the same principle. It
varies from that of Fig. 1 in that the plate B is flat without a flange, and that the
tightening is effected only on one side. A is a plate having a bent edge as in Fig. 1,
whilst B is flat; the square C forming a ledge and a tightening device has no
longer the same form as in Fig. 1; it is provided with a slot D in which moves
freely about a fixed knob E screwed into the plate B. The aperture for the
plate A is on one side as shown in the figure; it is completely open below for
enabling the bent edge of A to be introduced. The mattress bears upon the ledge F
which may be at the top or at the bottom of the part C and thus a tightening
device is formed.
Fig. 3 is an arrangement also based upon the same principle, but in which the
tightening action may be increased by the tightening of an accessory nut D turning
upon a screw threaded bolt E fixed in the aperture of the tightening part C. In
this figure are shown the parts A B and C corresponding to those designated
by the same letters in Fig. 1. As previously the bent edges are introduced into
the aperture, and the part C is caused to bear upon the said edges; the weight of
the mattress will produce a tightening action as in Fig. 1. If then I wish to
augment this tightening action the nut D is moved upwards until it touches the
bent edges of A and B; the upward movement is continued until the desired
degree of tightening has been obtained.
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. A system of fastening for connecting various parts of a bedstead consisting of
three parts, two of which are fixed separately to the two parts to be connected, and
upon their bent edges the direct tightening takes place with the third part having
a tapering aperture which is connected to a ledge for receiving the mattress; as
herein described and set forth.
2. The adaptation of a screw and nut to the aforesaid fastening for augmenting
the tightening action at will, as herein described and set forth.
