PROVISIONAL SPECIFICATION.
An Improved Machine for Making Hinges.
We HENRY STEVENS of the Firm of Joseph Stevens and Son of Hanley Works
Hanley Street Birmingham in the County of Warwick Hinge Makers and WILLIAM
AMES of the same place Engineer do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to save labour and time in the manufacture of
pressed hinges and consists in the formation of a machine as hereafter described.
The machine consists firstly of a bed carried by legs on the frame of this bed rise
standards to carry shafting which shafting carries a train of wheels.
A fly wheel is driven by a pulley passing over a main shaft this fly wheel having
a pinion wheel on its axle which gears into a spur wheel which spur wheel is carried
by the shaft that works the eccentric this eccentric causes a bolt to rise and fall this
bolt carries a jointing punch and sheer which on decending simultaneously punch
the hole for the joint and cut off the required length of metal for the hinge.
The next part of my invention refers to the use of two cams for the purpose of
raising and lowering a bolt which bends the hinge after being cut off by the before
mentioned sheer.
On the same shaft that carries the spur wheel is a chain wheel working between
the spur wheel and cam from this wheel a chain works over another wheel which
turns a shaft which shaft works on the far side of the frame by means of a disc
this disc being attached by a connecting rod to a sliding bolt for the purpose of
sliding the wire for the formation of the knuckle of the hinge.
On the shaft carrying the spur wheel, the cam is also carried which cam in its
revolution works a lever this lever being kept in position by a spring, to this lever
a connecting rod is attached working on to a bolt which gives the hinge the required
squeeze to form the knuckle round the above named wire the same operation which
forms the knuckle round the wire levels the hinge, and thus the parts are ready for
being put together.

An Improved Machine for Making Hinges.
We HENRY STEVENS of the Firm of Joseph Stevens and Son of Hanley Works,
Hanley Street Birmingham in the County of Warwick hinge makers and WILLIAM
AMES of the same place Engineer, 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 :-
The object of this invention is to save labour and time in the manufacture of
pressed hinges and consists in the formation of a machine as hereafter described.
The machine consists firstly of a bed carried by legs on the frame of this bed are
standards to carry shafting which shafting carries a train of wheels.
A fly wheel is driven by a pulley passing over a main shaft this fly wheel having
a pinion wheel on its axle which gears into a spur wheel which spur wheel is carried
by a shaft that works the eccentric, this eccentric causes a bolt to rise and fall, this
bolt carries a jointing punch and sheer which on descending simultaneously punch
the hole for the joint and cut off the required length of metal for the hinge.
The next part of my invention refers to the use of two cams for the purpose

page_text: of raising and lowering a bolt which bends the hinge after being cut off by the before
mentioned shear. On the same shaft that carries the spur wheel is a chain wheel
working between the spur wheel and cam, from this wheel a chain works over
another wheel, which turns a shaft which shaft works on the far side of the frame by
means of a disc, this disc being attached by a connecting rod to a sliding bolt for the
purpose of sliding the wire for the formation of the knuckle of the hinge. On the
shaft carrying the spur wheel the cam is also carried which cam in its revolution works
a lever this lever being kept in position by a spring. To this lever a connecting rod
is attached working on to a bolt which gives the hinge the required squeeze to form
the knuckle round the above named wire, the same operation which forms the
knuckle round the wire levels the hinge and thus the parts are ready for being put
together.
Referring to the drawings in which similar letters of reference, refer to similar
parts, Fig. 1. shews a front view, Fig. 2, one side view of the machine and Fig. 3 a
view of the reverse side (a) is the bed carried by legs (b) (c) are the standards
(d) Fig. 2 is the fly wheel driven by the band (e) on the cone pulley (e¹) upon the
shaft (f) which is supported on the brackets (2) (9) is a pinion wheel upon this
shaft which gears into the spur wheel (h) which spur wheel (h) is upon the centre
shaft (1) Fig. 3 parallel with the shaft (ƒ) Fig. 2 which shaft (2) works the eccentric (1)
which eccentric (2) causes the bolt (k) Fig. 1 to rise and fall. The bolt (k) carries
the jointing punch (1) and shear (m) which on descending simultaneously punches
the hole for the joint and cuts off the required length of metal for the hinge, (m¹) is
a regulating wheel for the purpose of regulating the punch to adapt it to the
thickness of the various sized hinges required to be punched there is also a similar
wheel at the back for the purpose of adjusting the bender (p) as hereinafter mentioned.
(o) is a cam upon the shaft (i) used for raising and lowering the bolt carrying the
bender (p) (which bender (p) bends the hinge after it has been cut off by the shear (m))
the strap () works upon the cam (o) for the purpose of causing it to raise the bolt
carrying the bender (p) after the first portion of the action of the cam has forced it
down () being a spring to govern the action of the strap-(³) is a roller bearing
against the side of the strap (¹) in order to ensure it having a perpendicular action.
On the shaft () is the chain wheel (9) working between the spur wheel (h) and
the cam (n) from this wheel a chain (r) works over the wheel or disc (s) and is
kept in position by the guide wheel (8¹)` This chain (r) turns the disc or wheel (s)
and thus propels and withdraws the shaft (t) to which shaft is connected the sliding
bolt (u) for the purpose of sliding the wire over which the metal is folded in forming
the knuckle of the hinge seen in Fig. 1.
On the shaft (2) Fig. 3 is the cam (n) which in its revolution works the lever (v)
which lever (v) is kept in position and to its work by the spring (w) which draws
back the connecting rod (c) after the revolution of the cam (n) has caused the lever (v)
to drive it forward the connecting rod (a) working onto the bolt (y) ((y)) being a
lubricator for lubricating the wire] the bolt (y) gives the hinge the required squeeze
to form the knuckle round the before mentioned wire levelling the hinge at the same
operation, the two parts of the hinge are then completed and ready to be put
together.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
The construction and use of a machine for making pressed hinges substantially
as herein set forth and specified whereby the several processes hitherto adopted are
executed almost simultaneously and thereby saving much labour and expense in the
production of such hinges.
