PROVISIONAL SPECIFICATION.
Improvements in Hinges.
I, THOMAS JENNER of Mill Lane. Taunton, in the County of Somerset,
Brewery Proprietor, do hereby declare the. nature of this invention to be as
follows:-
According to this invention I construct hinges in such manner as to open to a
predetermined angle only and to possess great strength while offering no projection
as the knuckle or joint part in the usual form of hinges. For this purpose I form
the hole for the joint pin in the end lugs of the one hinge half or part and make the
said end lugs of such a shape as to form a firm bearing or abutment against the
body of the other or complementary hinge part, at right angles thereto or at any
other predetermined angle, the lugs on the said complementary hinge part projecting
or rising therefrom at the same right angle or other predetermined angle. The
hinge is by preference made stronger at the hinge joint or angle but presents no
projection on the inner sides so that the two parts will fold close upon each
other.
Additional abutments may also be formed by giving the lugs of the
complementary hinge part square corners which abut against corresponding square
corners between the lugs of the other hinge part. Hinges made as described are
especially suitable for boxes musical instruments folding desks, bureaux and other
furniture and also for street doors and inner doors the lock part of which is thus
prevented from injuring the wall of the passage or hall when thrown open. Hinges
constructed according to this invention are also especially suitable for applying to
folding packing cases.

COMPLETE SPECIFICATION.
Improvements in Hinges.
I, THOMAS JENNER of Mill Lane, Taunton, in the County of Somerset,
Brewery Proprietor 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 :-
According to this invention I construct hinges in such manner as to open to a
predetermined angle only and to possess great strength while offering no projection
as the knuckle or joint part in the usual form of hinges. For this purpose I form
the hole for the joint pin in the lug or lugs of the one hinge half or part and make
said lug or lugs of such a shape as to form a firm bearing or abutment against the
body of the other or complementary hinge part at right angles thereto or at any
other predetermined angle, the lug or lugs on the said complementary hinge part
projecting or rising therefrom at the same right angle or other predetermined
angle. The hinge is by preference made stronger at the hinge joint or
angle but presents no projection on the inner sides so that the two parts
will fold close upon each other. Additional abutments may also be formed
by giving the lugs of the complementary hinge part square corners which abut
against corresponding square corners between the lugs of the other hinge part.
Hinges made as described are especially suitable for boxes, musical instruments,
folding desks, book slides, bureaux and other furniture and also for tail boards of
[Price 8d 1

page_text: dog carts, for railway carriage doors and for street doors and inner doors the lock
part of which is thus prevented from injuring the wall of the passage or hall when
thrown open. Hinges constructed according to this are also especially suitable for
applying to folding packing cases.
In the perspective views Figs. 1. and 2 I have such a hinge differing only in the
form of the inner faces and intended to be wholly or partly let into the wood or
other material of the desk and its flap or of other piece of furniture or used for
doors. The hinge is shewn to open only to about 90° but may obviously be made
for any less or greater angle. The hole for the joint pin a is formed in the lugs
of the one hinge half or part, the lugs being made of such a shape as to form a
firm bearing or abutment against the body of the other or complementary hinge
half, the lugs on the latter projecting or rising therefrom at the desired angle
which in these examples is 90°. The hinge is by preference as shewn made stronger
at the hinge joint or angle so that it is let deeper and firmer into the wood at this
place but presents no projections on the inner sides so that the two halves of the
hinge will fold close upon each other.

Additional abutments may also be formed as shewn in Fig. 1 which is a cross
section on line A B Fig. 1. by making the lugs of the complementary hinge half
with square corners which abut against corresponding square corners between the
lugs a of the other hinge half.
Fig. 3. is a perspective view of a hinge of a slightly different form and made to
open wider than 90°. The stops or abutting surfaces are at the places e and which
being comparatively small can easily be fitted exactly as desired by the aid of a
file. The lugs may be chamfered off as shewn in dotted lines at g.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
°
1. Hinges in which the one half is made with joint pin lug or lugs in continuation
of the body and the other half made with a joint pin, lug or lugs, standing up from
the outer face of the body so that the lug or lugs on the one may form abutment
against some part of the other hinge half according to any desired opening angle
substantially as set forth.
2. The hinge constructions shewn in the drawing.
