IMPROVEMENTS IN HINGES
Year: 1885

page_text: I WILLIAM RICHES of 22 Baldwin's Gardens, Gray's Inn Road, in the county
of Middlesex, Builder do hereby declare the nature of the said invention for
"IMPROVEMENTS IN HINGES" to be as follows:-
These hinges which may be called accommodation binges because they permit
of movements not to be obtained with ordinary hinges, are constructed, one leaf
with a projecting pin or equivalent and the other leaf with a recess groove, or
equivalent The shape of this groove may be varied to any desired extent to suit
circumstances thus for a simple hanging lid a short straight groove. would suffice,
this would allow the lid to be raised clear of any fastening and turned over & laid
upon the top of the cupboard or other article.
For a desk or the like where the lid was required to slide back with or without
turning over a short vertical groove. would allow of any rise that might be needed
and a long horizontal groove would permit of the lid being slid back out of
the way.
In some cases a circular groove may be used, in others semi circular with a
straight base.

Improvements in Hinges.
I WILLIAM RICHES of 22 Baldwin's Gardens, Gray's Inn Road in the County
of Middlesex, Builder, 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 :-
These hinges which may be called accomodation hinges because they permit of
movements not to be obtained with ordinary hinges, are constructed one leaf with
a projecting pin or equivalent, and the other leaf with a recess groove or equivalent.
The shape of this groove may be varied to any desired extent to suit circum-
stances; thus for a simple hanging lid a short straight groove would suffice, this
I would allow the lid to be raised clear of any fastening and turned over and laid
upon the top of the cupboard or other article.
For a desk or the like where the lid was required to slide back with or without
turning over a short vertical groove would allow of any rise that might be needed
and a long horizontal groove would permit of the lid being slid back out of
the way.
In some cases a circular groove may be used: in others semicircular with a
straight base,
In the accompanying drawings Figures 1 and 2 are views in different positions
of the hinge with a single short slot; Figure 3 shows a hinge plate with one short
slot and one long one and Figure 4 shows the plate with a continuous slot one
portion being straight and the other curved. Figure 5 is an edge view of the
hinge the slotted portion being shown in section. These views are merely given
as representing the general principle of the hinge, but the form of the grooved
plate may be to any required extent.
:
This hinge is in two portions or leaves one of which has a pin or projection and
the other a groove or equivalent in which the pin moves; one of these leaves is
placed upon the lid and the other upon the box, but it is inmaterial which leaf is
placed upon the box and which upon the lid, it is simply a matter of convenience.
In Figure 1 the pin portion A of the hinge is placed upon the box C and the
slotted portion B upon the lid D. This figure shows a hanging lid which is
supposed to be closed and its bottom edge engaged with some portion of the frame-
work of the box or other article to which it is attached. The lid D can be raised
up the length of the slot B and then turned round as with an ordinary hinge and
folded back as in Figure 2.
With the slotted plate B shown in Figure the lid after being raised up the
small portion B₁ of the slot could be turned upon the pins A¹ and be moved in a
horizontal direction for the length of the long portion B' of the slot.
It is evident that the form of this hinge may be modified without departing
from the spirit of the invention. For instance in place of the slot or groove a
dovetail ridge curved to the required shape might be adopted with which would
engage a projection having a dovetail slot in place of the pin.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In a hinge the combination of a leaf or plate such as A having a pin or pro-
joction with a second leaf or plate such as B having a slot with which said pin or
projection engages substantially as and for the purpose specified.
2. The herein described accomodation hinge which admits of both a turning and
sliding movement substantially as specified.
