1.
I PATRICK O'CONNOR of 11 and 13 High Street Wavertree in the County of
Lancaster Hinge Manufacturer, do hereby declare the nature of my said invention
for IMPROVEMENTS IN SPRING' HINGES FOR DOORS" to be as follows
The invention relates to hinges which consist essentially of a spindle attached
to the door and a box or receptacle fitted with bearings and spring appliances for
carrying and giving motion to the spindle and door.
The objects are mainly to provide easy means for adjusting the position in which
the door is held by the spring appliances and to facilitate the construction of the
parts.

The invention consists essentially in combining a carrying frame having bearing
pieces and adjusting screws with the footstep or end bearing of the spindle and the
spring appliances or working parts for actuating the said spindle and in fitting the
said combined frame and parts within the box or receptacle so as to be movable
horizontally therein by means of the adjusting screws.
In practice I prefer to employ in combination a footstep, guides, a slide, springs
and adjusting screw operating substantially as setforth in the specification to British
Letters Patent No 565 of the year 1877 granted to me I connect the said parts
together and I provide projections or guide pieces and adjusting screws so situated
and proportioned as to retain the combined apparatus in position when fitted within
the box or receptacle. A movable cover is provided for the said box or receptacle.
Apparatus so made and fitted is capable of being moved within the box or receptacle
circumferentially around the axis of the footstep or end bearing and is secured in
the desired position by means of the adjusting screws.
It will be obvious that by moving the spring appliances for actuating the spindle
as above setforth the position of the door may be altered.

DESCRIPTION OF THE DRAWINGS.
Fig 1 is a plan of the box or receptacle containing the frame and spring appliances
or working parts, and fig 2 is a side elevation of the frame.
a is the carrying frame, 6 bearing pieces, c position adjusting screws, & foot step
for the spindle e, f guides on frame a g slide fitting in guides f, h spring, i tension
adjusting screw and resistance piece for spring, j box or receptacle into which the
frame a fits, le top bearing for spindle e secured to box or receptacle j by screws 1,
m cover. The door is fitted at the bottom with a strap or piece which takes onto
the square head of the spindle e; and the said door has its position adjusted radially
by altering the position of the frame a in the box j by means of the screws c.
The
box or receptacle j is secured in the floor beneath the door in the usual manner

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:-
First. The combination in spring hinges of a box or receptacle j a frame a, and
spring appliances or working parts substantially as setforth.
Second. The combination in spring hinges of the frame a bearing pieces b screws c
and footstep & substantially as setforth.
Third. The combination in spring hinges of the frame a adjusting screws c foot-
step d and box or receptacle j substantially as setforth.
