Improvements in Hinges.
I, JOHN PRIEST, a member of the Firm of Benjamin Priest & Sons, of Pro-
vidence Works, Old Hill, Staffordshire, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention has reference to that class of hinges for doors gates and the
like in which the hinge pin is fixed in the eye of the strap and projects above
and below the same these projecting parts turning in stationary top and bottoni
sockets carried by the door post, and this invention consists of the improved
means for fixing the hinge pin in the eye of the strap to prevent the strap from
moving down the pin and riding on the bottom socket and also improvements
in the construction and arrangement of the top and bottom sockets and their
fixing plate to facilitate the removal of the door and strap and hinge pin from
the said top and bottom sockets as herein described.
According to one part of this invention I fix the hinge pin in the eye of the
strap part of the hinge by making that part of the hinge pin which is enclosed
in the said eye of rather smaller diameter than the parts of the hinge pin which
project beyond the eye, this part of smaller diameter terminating in shoulders
between which the strap of the hinge fits and thus the pin is prevented from
moving endwise in the eye of the strap. In fixing the hinge pin and the strap
together the strap has to be closed over and around the smaller part of the
hinge pin and if necessary secured by a rivet. Or the hinge pin may be pre-
vented from moving endwise in the eye of the strap by the hinge pin having
two collars forged or otherwise formed or fixed on it one collar immediately
above and the other collar immediately below the strap so that the strap fits in
between these two collars and thus the pin is prevented from moving endwise.
Or the hinge pin may be prevented from moving in the strap by the hinge
pin having a groove or recess formed in that part which is enclosed in the
strap and then after the pin has been placed in position in the eye the metal of
the eye is pressed into the said indentation or groove of the pin and thus the
latter is effectually secured to the strap.
In order to facilitate the removal of the door with the strap part of the
hinge and the hinge pin from the top and bottom sockets when required, I con-
struct and arrange the said top and bottom sockets and their fixing plate as I
will now. describe. The bottom socket in which the hinge pin turns is formed
with or fixed to a back plate adapted to be fixed by screws or the like to the
door post. The top socket is made separate from the back plate and secured
thereto by the top socket having a dovetailed part adapted to slide in a corre-
sponding vertical dovetailed slot or groove in the back plate. A pin in the
back plate. engaging in a recess in the back of the top socket prevents the latter
from being moved up too far. When it is desired to remove the strap and the
hinge from the bottom socket this can readily be done by raising and sliding
the top socket along the base plate far enough to permit of the hinge pin being

page_text: lifted out of the bottom socket. When the hinge pin is reinserted in the bottom
socket it is only necessary to lower the top socket so as to embrace the upper
part of the hinge pin and thus keep the latter is place. So as the better to take
up the wear of the hinge pin and reduce the friction on the lower end of the
same the bottom socket is by preference provided with a set. screw in a line
with the axis of the hinge pin, this set screw being screwed into the socket and
the head of the same projecting below the socket. The hinge pin turns on
the top of this set screw so that by turning the latter the hinge pin can be
raised if necessary to take up wear and prevent the strap from working on the
top of the bottom socket.

I, JOHN PRIEST, a member of the Firm of Benjamin Priest & Sons, of Pro-
vidence Works, Old Hill, Staffordshire, Manufacturer, 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 reference to that class of hinges for doors gates and the
like in which the hinge pin is fixed in the eye of the strap and projects above
and below the same these projecting parts turning .n stationary top and bottom
sockets carried by the door post, and this invention consists of the improved
means for fixing the hinge pin in the eye of the strap to prevent the strap from
moving down the pin and riding on the bottom socket and also improvements
in the construction and arrangement of the top and bottom sockets and their
fixing plate to facilitate the removal of the door and strap and hinge pin from
the said top and bottom sockets as herein described.
ייג
I will describe my invention by referring to the accompanying drawings on
which Fig. 1 is a side sectional elevation of a hinge constructed according to
this invention; Fig. 2 is a front elevation of the same partly in section and
Fig. 3 shews the hinge pin separately; Fig. 4 is a front elevation partly in
section of a modified arrangement of my invention and Fig. 5 is a separate view
of the hinge pin belonging to the hinge represented in Fig. 4; Fig. 6 is a
modified form of the hinge pin for the hinge represented by Fig. 4; Figs. 7 and 8
illustrate a further modification of my invention; Fig. 9 is a sectional elevation
and Fig. 10 is a front elevation of another hinge constructed according to this
invention; Fig. 11 is a sectional plan of the same; Figs. 12 and 13 shew parts
of the said hinge separately; and Figs. 14 15 and 16 illustrate a further slight
modification of my invention.
The same letters of reference indicate the same or corresponding parts. in all
the figures of the drawings.
Referring firstly more particularly to Figs. 1, 2 and 3, according to one part
of this invention I fix the hinge pin A in the eye b of the strap part B of the
hinge by making the part a¹ of the hinge pin which is enclosed in the eye b
of rather smaller diameter than the parts an² of the hinge pin which project
beyond the eye this part al of smaller diameter terminating in shoulders a³ at
between which the strap B of the hinge fits and thus the pin A is prevented
from moving endwise in the eye brof the strap B. In fixing the hinge pin. A
and strap B together the strap B has to be closed over and around the smaller

page_text: part a of the hinge pin and if necessary secured by a rivet such as c. It will
be understood that the rounded end portions of the hinge pin A turn in the
top socket D and in. the bottom socket 12 in the usual way these top and bottom
sockets being constructed in the usual manner for fixing to the door posts or
as indicated by dotted lines in Fig. 1 they may as usual be made separate from
and fixed to a back plate E or one of the sockets usually the bottom one D may
be formed in a piece with the said back plate.
In a modification of this part of my invention (see Figs. 4 and 5) the hinge
pin A is prevented from moving endwise in the eye b of the strap B by the
hinge pin A having two collars marked respectively a forged or otherwise
formed with it the collar as being immediately above the strap B and the other
collar a being immediately below the strap B so that the strap fits in between
these two collars and thus the pin A is prevented from moving endwise.
Instead of the collars being forged or otherwise formed with the hinge
pin A the said collars as a may as shewn in Fig. 6 be made separate from the
pin A in the form for instance as wire rings and closed into grooves a which are
formed in the pin A.
In the modification of my invention illustrated by Figs. 7 and 8 the hinge
pin A is made parallel throughout and is prevented from moving in the strap B
by the hinge pin A having a groove or recess as in the part which is enclosed in
the strap B and then after the pin A has been placed in position in the eye b
the metal of the eye is for instance at 62 63 pressed into the said indentation as
or groove of the pin A, and thus the latter is effectually secured to the strap B.
In order to facilitate the removal of the door with the strap part B of the
hinge and the hinge pin A from the top and bottom sockets D¹. D² when
required, I construct and arrange the said top and bottom sockets and their
fixing plate as I will now describe by referring to Figs. 9, 10, 11, 12 and 13.
The bottom socket D2 in which the hinge pin A turns is formed with or fixed
to the back plate E and adapted to be fixed by screws or the like to the door
post. The top socket D¹ shewn separately in Fig. 13 is made separate from the
back plate E and secured thereto by the top socket D' having a dovetailed part
adapted to slide in a corresponding vertical dovetailed slot or groove e¹ in the
back plate E. A pin f fixed in the back plate E and engaging in a longitudinal
recess in the back of the top socket D¹ prevents the latter being moved up too
far. When it is desired to remove the strap B and the hinge pin A fixed thereto
from the bottom socket D2 this can readily be done by raising and sliding the
top socket D up this plate E (see Fig. 10) far enough to permit of the hinge
pin A being lifted out of the bottom socket. When the hinge pin A is
re-inserted in the bottom socket D2 it is only necessary to lower the top socket D'
so as to embrace the upper part of the hinge pin A and thus keep the latter in
place.
So as the better to take up the wear of the hinge pin A and reduce the
friction on the lower end of the same the bottom socket D in any of the said
hinges is or may be provided with a set screw G (see Figs. 9 and 10) in a line
with the axis of the hinge pin A this set screw being screwed into the socket
and the head of the same projecting below the socket. The hinge pin A
turns on the top of this set screw G so that by turning the latter the hinge pin
can be raised if necessary to take up wear and prevent the strap B from working
on the bottom bracket D.
Fig. 14 shews another arrangement of the set screw G on which the hinge pin A
turns. In this case the hole in the socket D2 is not tapped to receive the set
screw G and the latter is adjusted by the nut which fits on said screw and
works in a slot in the socket D².
Figs. 15 and 16 shew the same arrangement of adjusting screw G and nut g²
as in Fig. 14 but applied to other kinds of bottom sockets 12; the bottom
socket D2 having the fixing base extended at both sides in Fig. 15 and only
at one side in Fig. 16.
