PROVISIONAL SPECIFICATION.
Improvements in Hinges applicable for Screens, Folding Doors,
Clothes' Maidens, and the like.
I WILLIAM GLAZIER, of 37, Virginia Street, Southport in the County of
Lancaster, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a hinge that will fold both ways, that is 180
degrees. It is also applicable for cheaper hinges that will only fold to a lesser
number of degrees. I form the two edges of the door to be united or the door and
its post of a circular contour and place in each circle a rack gearing into the other..
I unite the two centres with a link. Preferably there are two pairs of racks and
two links, one pair and link being near the top the other near the bottom. The
link if desirable can be immediately on the rack, or it can be on the top of the door
and screen.
In cheap screens it is at the top and is simply attached to the top and
bottom of the wood by means of a screw. In more expensive or heavier ones the
top and bottom are iron plated and the link is screwed to these iron plates. In
some instances the racks have lugs which are firmly screwed to the wood-work like
hinges and in that case I may attach the link directly to the racks. In place of
two racks I may use only one rack and a pad of india-rubber or other elastic.
material into which the teeth of the rack work.

COMPLETE SPECIFICATION.
Improvements in Hinges applicable for Screens, Folding Doors,
Clothes' Maidens, and the like.
1, WILLIAM GLAZIER of 37, Virginia Street, Southport in the County of
Lancaster 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 has for its object a hinge that will fold both ways, that is, 180
degrees, but it is also applicable for cheaper hinges that will only fold to a less
number of degrees.
The invention will be understood from the following description, reference being
had to the accompanying drawings, in which-
Figure 1 is a side elevation partly in section; and
Figure 2 a plan with the link broken away.
I form the two edges A to be united of a semi-circular contour, and place in
cach semi-circle a rack B, gearing one into the other. These racks have lugs
which are firmly screwed to the wood work like hinges, and the two centres of the
racks are united directly by a link D. There may be two or more pairs of racks B
and two or more links, one pair and a link being near the top of the door, screen
or other article, and another near the bottom. The links, as shown on the
drawings, are immediately on the racks, being pivotted thereto by rivets or their
equivalent.
In cheap screens, however, the link may be at the top and bottom of the door,
screen, etcetera, being simply attached to the wood by means of a screw.
In more
expensive or heavier ones, the top and bottom are iron plated, and the link is
screwed to these iron plates.

page_text: In place of two racks, I may use only one rack let into one of the edges A to be
united, and a pad of indiarubber or other elastic material secured to the other
edge, into which the teeth of the rack work."
"
The hinge is applicable for screens, folding doors, clothes maidens, or the like,
and, when used for doors, one of the racks is secured to the door, and the other to
the post.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvement in hinges for screens, folding doors, clothes maidens, or the
like, which consists in forming them of a pair of semi-circular racks gearing one
into the other, or of a single rack, and a semi-circular pad of elastic material into
which the teeth of the rack work, the centres of the racks or the rack and the pad
being coupled together by a link to maintain them at the proper distance apart,
substantially as described.
2. The general combined arrangements and constructions of parts forming the
improved hinge substantially as described.
