PROVISIONAL SPECIFICATION.
A Combined Postal, Electric Signal Alarm, and Telephone Pillar.
We, EDWARD HASSELBACH, Telegraph Engineer MAURICE HENRY HYMAN, Diamond
Merchant, and JACOB ALEXANDER ALEXANDER, Avertising Agent all of the City of
Melbourne in the Colony of Victoria do hereby declare the nature of this invention
to be as follows:-
This invention consists of a combined postal, electric signal alarm and telephone
pillar. It has been designed to allow of postal pillars (of about the external
dimensions of those at present employed in the streets) being also used as a telephone
stand and as an electric alarm signal stand for the police, fire brigades, ambulance
or for other purposes.
As an alternative the top or alarm box portion of the invention
may be mounted on other pillars or posts, or secured to walls in the streets as may
be found most convenient for the alarm signal service.
The postal pillar is made of a polygonal or circular section and vertically constructed
either in one casting, or in two or three sections. When made in sections they are
securely bolted together. The top section is divided into compartments and furnished
with doors having panels of glass, wood, or iron with a spring catch or lock to allow
access to the electric alarms or telephone transmitting and receiving instruments.
An automatic indicator is fitted in the panel above letter box to shew the times of
clearance of the postal pillar. Further an electric light may be arranged either over
the crown or in one of the upper panels in conjunction with a clock.
The top section is of an ornamental character surmounted by a crown while the
wall box or section is constructed with a flat back, having holed lugs to allow of its
being bolted in position.
The central section or postal part of the pillar bas part of its side made up of the
door which is hung on upper and lower pintles passing into the upper and lower
sections or the door may be hung by hinges of other descriptions. Attached to the inside
of the door is a metal receiving receptacle for the letters such receptacle having a closed
top and a hinged bottom to allow of its contents being delivered to the letter carrier's
bag. The outside of the letter receiving slit is furnished with a flap cover, while
over its inner opening are hung a number of closely arranged pointed steel wires
after the manner of a comb, so as to prevent the withdrawal of letters by hooks or
otherwise. The inside of the door also bears a tappet to work the arm of an
automatic clearance indicator.
The lower section is divided into two compartments and it is provided with flanges
or lugs to allow of its being bolted to a wood or other bedding laid in the ground.
In the bottom section is fitted an earth pipe with a T piece to carry wires from
instruments. The floors and covers of the sections are made of wood or iron. The
lower compartment is to contain batteries and connections for the wires leading to
the electric alarms and telephones in the top of the pillar.

A Combined Postal, Electric Signal Alarm, and Telephone Pillar.
We EDWARD HASSELBACH, Telegraph Engineer, MAURICE HENRY HYMAN, Diamond
Merchant, and JACOB ALEXANDER ALEXANDER Advertizing Agent, all of the City of
Melbourne in the Colony of Victoria, 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 a combined postal, electric signal alarm and telephone
pillar. It has been designed to allow of postal pillars (of about the external dimensions
of those at present employed in the streets) being also used as telephone stands and
as electric alarm signal stands for the police, fire brigades, ambulance, and for other
purposes. Further, an electric light may be arranged either over its crown or in
one of the upper panels in conjunction with a clock. As an alternative the top or
telephone and alarm box portion of the invention may be mounted on other pillars
or posts, or secured to walls in the street as may be found most convenient for the
service.
In the attached drawings,
Fig. 1 is a front elevation of the pillar and
Fig. 2 a side view of it shewing the postal and upper parts in section with the
door carrying the letter receiving receptacle open.
Fig. 3 is a horizontal section on line a a Fig. 1 and
Fig. 4 a sectional plan on line 6 b Fig. 1.
Figs. 5 are details of the automatic clearance indicator.
Fig. 6 is a front view of the wall box, and
Fig. 7 a plan of it.
The postal pillar A is made of a polygonal or circular section and vertically
constructed in one casting or in two or three sections. When made in sections they
are securely bolted together. The top section A¹ is divided into compartments A²
and furnished with doors A³ having panels of glass wood or iron, with a spring catch
or lock to allow access to the electric alarms B or telephone transmitting instruments C.
These doors are connected with an electric call bell which is brought into contact
by the opening of the door. An automatic indicator D is fitted in the panel above
letter box E to shew the times of clearance of the postal pillar.
The top section A¹ is of an ornamental character surmounted by a crown A' above
which is shewn an electric lamp A³. The wall box or section F is constructed with
a flat back, having holed lugs F to allow of its being bolted in position.
The central section or postal part of the pillar has part of its side made up of the
door E¹ which is hung on upper and lower pintles passing into the upper and lower
sections, or the door may be hung by other descriptions of hinges. Attached to
the inside of the door is the metal receiving receptacle E for the letters, such
receptacle having a partially closed top and a hinged bottom E2 (to allow of its
contents being delivered to the letter-carriers bag). The outside of the letter receiving
slit is furnished with an ordinary cover, while over its inner opening are hung a
number of closely arranged pointed steel wires E3 after the manner of a comb, so
as to prevent the withdrawal of letters by hooks or otherwise. The inside of the
door also bears a tappet E to work the arm of the automatic clearance indicator D
which consists of the pivotted box arm D¹ having a stem at its bottom and acted on
at its top by a spring D², while to the upper end of one arm is centred a ratchet
bar D³ gearing with a ratchet wheel D* arranged on a spindle upon which is also
a cam wheel D' acted on by a spring stop D. "D' is the dial plate and D³ the pointer
or hand.
The lower section is divided into two compartments and it is provided with flanges
or lugs to allow of its being bolted to a wood or other bedding laid in the ground.
In the bottom section is fitted an earth pipe T to carry wires from instruments.
The floors and covers of the sections are made either of wood or iron. The lower

page_text: compartment is to contain batteries and connections for the wires leading to the
electric alarm and telephones in the top section of the pillar.
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 :-
1st. The combination with postal pillars of a divided upper section arranged for
the reception of telephones and electric alarm signals substantially as herein described
and explained and as illustrated in our drawings.
2nd. The wall box or alternative construction of divided section for telephones and
electric alarm signals substantially as herein described and explained and as illustrated
in Figs. 6 and 7 of our drawings.
3rd. The combination with the pillar box door of the letter slit having wires hung
over it, the letter receptacle having a hinged bottom and a partially closed top and
the automatic indicator dial substantially as herein described and explained and as
illustrated in our drawings.
