BABONNEAU, all of 45, Avenue d'Antin, Paris, France, Coach-makers and Saddlers,
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved arrangement of metal work (hereinafter
referred to as iron-work) for the hoods of vehicles, and has for object to obviate the
inconveniences attending the employment of ironwork as ordinarily constructed for
this purpose, such being dangerous to operate by hand, and furthermore not being
capable of ready removal, thus also preventing the ready removal of the hood.
The invention comprises an improved compass joint, and an improved arrangement
of tenon An example of each is shown in the annexed drawing.
Fig. 1 is a front elevation of the improved compass joint closed ;
Figs. 2 and 3 are side views;
Fig. 4 shows the joint open ;
Fig. 5 is a front elevation of the improved tenon; and
Fig. 6 is a section through the same.
As shown, the improved compass joint consists of two branches a and b with
female and male parts respectively, these parts being connected by a pin c and jointed
one upon the other by means of a lense d cut away circularly to allow for the play
of the female branch, whose end for that purpose has a curved portion towards the
centre of the joint, as shown in Fig. 4.
In this way, the possibility of the hand getting in between the two branches of the
iron-work or inside the joint, as often happens with iron-work as ordinarily constructed,
is avoided

page_text: The improved tenon is composed of three parts screwed together. It consists of an
arresting plate or catch e in which the tenon proper f is screwed. The latter is
provided with bearing parts g, h, on. which is screwed the nut i which secures the
loop (formed in one piece with the upper branch ) of the iron-work, as shown in
Fig. 5. This arrangement of tenon obviates disadvantages heretofore affecting that
part, and renders possible the ready replacement of the same, and the ready removal
of the hood, or of the whole of its ironwork.

Improvements in or Pertaining to Hoods for Vehicles.
We GEORGES RODUWART, LOUIS RODUWART and EMILE JEAN FRANÇOIS IGNACE
BABONNEAU, all of 45 Avenue d'Antin, Paris, France, Coach makers and Saddlers
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 an improved arrangement of metal work hereinafter
referred to as ironwork for the hoods of vehicles and has for object to obviate the
inconveniences attending the employment of ironwork as ordinarily constructed for
this purpose such being dangerous to operate by hand and furthermore not being
capable of ready removal thus also preventing the ready removal of the hood. The
invention comprises improvements in compass joints, and an improved arrangement
of tenon. Referring to the sheet of drawings filed with the Provisional Specification
and the additional sheet of drawings annexed to this specification
Fig. 1 is a front elevation of an improved compass joint closed.
Figs. 2 and 3 are side views.
Fig. 4 shows the joint open.
Fig. 5 is a front elevation of the improved tenon and
Fig. 6 is a section through the same.
As shown, the improved compass joint consists of two branches a and b with
female and male parts respectively these parts being connected by a pin c and
jointed one upon the other by means of a lense d cut away circularly to allow for the
play of the female branch whoso end for that purpose has a curved portion towards the
centre of the joint, as shown in Fig. 4.
In this way, the possibility of the hand getting in between the two branches of the
ironwork or inside the joint, as often happens with ironwork as ordinarily constructed
is avoided.
Fig. 7 is an elevation of a modified form of joint according to this invention, so
arranged as to resist ill-applied or undue pressure exerted in lowering or raising a
hood It shows the joint partly bent.
Fig. 8 is a plan of the same.
Fig. 9 shows the joint completely folded.
Fig. 10 shews another modification in side view and partly folded.
Fig. 11 is a plan of the same.
In order to render the joint capable of resisting transverse pressure indirectly
or accidentally applied in lowering or raising the hood, it is constructed with
single joint piece a connected with a double joint piece b, the two being held
together by a rivet cas in Fig. 8, or by a pin d, as shewn in Fig. 11.
a
In the joint shewn in figs. 7 to 9 the fingers of the person opening it will be pushed
safely out by the curved form of the back of the pieces a and b, while in the joint
shewn in Figs. 10 and 11 security is obtained by the circular piece d.

page_text: The improved tenon is composed of three parts screwed together. It consists of
an arresting plate or catch e in which the tenon proper of fis screwed. The latter is
provided with bearing parts gh on which is screwed the nut i which secures the
loop (formed in one piece with the upper branch of the ironwork), as shewn in
Fig. 5. This arrangement of tenon obviates disadvantages heretofore affecting that
part, and renders possible the ready replacement of the same, and the ready removal
of the hood or of the whole of its ironwork.
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 joint for the hoods of vehicles consisting of two branches connected by an
axis and provided with an eccentrically arranged circular piece d which prevents the
fingers of the person manipulating the joint being pinched substantially as described
with reference to Figs. 1 to 4 of the drawing.
2. A joint for the hoods of vehicles consisting of two branches, the one with a single
joint piece and the other with a double joint piece and the two being so arranged as
to prevent the fingers of the person manipulating the joint being pinched, substantially
as described with reference respectively to Figs. 7 to 9 and to Figs. 10 and 11.
3. A tenon for the ironwork of the hoods of vehicles consisting of three parts
connected by a central screw on which moves the loop ; forming part of the upper
branch of the ironwork, substantially as described with reference to Figs. 5 and 6 of
the drawings.
