PROVISIONAL SPECIFICATION.
Improvements relating to Pins or Bolts for Cycle and like Parts.
I, ALFRED CECIL WRIGHT, trading as James Warne, of 56-57 Watery Lane, in
the City of Birmingham, Manufacturer, do hereby declare the nature of this
invention to be as follows:--
This invention consists of improvements relating to seat pillar socket pins for
cycles and to similar pins or bolts for like services, my object being to construct such
pins of
greater efficiency or durability and at less cost, than by the existing ordinary
processes of manufacture.
In constructing such a pin or bolt in accordance with my invention, I employ rods
or wire of exactly the diameter of the pins required and I pass each rod or the wire in
a cold state, through a feeding die mounted on any suitable machine which is driven
by belting from a power driven shafting, or otherwise.
From the feeding die the wire is caused to enter a two part die formed at its
forward end to give the required shape to the head of the pin or bolt, and for the
formation of the snug or projection, to prevent the pin from turning or revolving
when in service. Such head and snug are produced by a reciprocating head or
plunger which presses the projecting end of the metal into the die. The pin is then
cut away from the rod or wire by a lateral movement of the two part or forming die
in relation to the feeding die, and is discharged by the next forward movement of
the rod into the required position for the making of another pin.
The pins produced by my improved process require no turning or machining on
the stem or body, beyond the screw threading of the ends; the heads are machined
or finished in any ordinary manner.
Improvements relating to Pins or Bolts for Cycle and like Parts.
I, ALFRED CECIL WRIGHT, trading as James Warne of 56-57 Watery Lane, in the
City of Birmingham, 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 consists of improvements relating to seat pillar socket pins for
cycles and to similar pins or bolts for like services, my object being to construct
such pins of greater efficiency or durability and at less cost, than by the existing
ordinary processes of manufacture.

page_text: In the accompanying sheet of explanatory drawings to be hereinafter referred to,
Figures 1, 2, and 3, represent three forms of bolts of pins made in accordance
with my invention.
Figure 4 is a sectional elevation and Figure 5. a plan of the machine by which the
said bolts or pins are produced, such views being drawn to a smaller scale than the
Figures 1, 2, and 3.
In the manufacture of pins or bolts, such as illustrated, in accordance with my
invention, I employ rods or wire of exactly the diameter of the pins required, and I
pass each rod or the wire in a cold state through a clutch or feeding die as A mounted
on a rivet making or like machine such as illustrated at Figures 4 and 5, and which
is driven by belting from a power driven shafting, or otherwise.
From the clutch or feeding die A the wire is carried forward by the action of the
rod A¹ operated by the crank plate A2 and is caused to enter a two part die B being
held by such die during the formation of the head of the pin or bolt, and of the
snug or projection C, (Figures 1, 2, and 3), to prevent the pin from turning or
revolving when in service. Such head and snug are produced by a reciprocating
head or plunger D which presses the projecting end of the metal into the properly
shaped mouth of the die. The pin is then cut away from the rod or wire by a
lateral movement of the guide and cutting plate E in relation to the feeding die
or clutch A and the two part die B, and is discharged by the next forward movement
of the rod into the required position for the making of another pin.
The pins produced by my improved process require no turning or machining of
the stem or body, beyond the screw threading of the ends; the heads are machined
or finished in any ordinary manner.
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:
The production of pins or bolts for cycle and like parts substantially as described
and as mustrated.
u as mustrated.
