PROVISIONAL SPECIFICATION.
Improvements in or connected with Pillar or Wall Letter Boxes, and
in the Method of Attaching thereto and to Walls or Buildings
Coin Operating or Automatic Delivery Machines.
I, JOSEPH FRAZER of 57 Holborn Viaduct in the County of Middlesex
Merchant do hereby declare the nature of this invention to be as follows:-
The object of my invention is to enable coin operating or automatic delivery
machines employed for the distribution of postage stamps to be securely attached
to pillar and wall letter boxes and to walls or buildings in such manner that they
will not project therefrom whilst they will be easily removable without disturbance
to the pillar or wall letter box or wall or building.
For this purpose I cast or otherwise form the pillar letter box with a recess or
chamber in the side or front thereof in such manner that it does not communicate
with the interior of the letter box and I form the recess or chamber open at the
top and with flanges at the front to enable the automatic delivery machine to be
slidden into position therein or I form it closed at the top and introduce the machine
at the open front thereof and I fix the machine in position by means of a screw or
screws passing through the back or side thereof and entering the back or side of
the recess or chamber.
In applying my invention to projecting wall letter boxes I form the recess or
chamber in either of the modes above described but in the case of letter boxes
embedded in walls or buildings I form the recess or chamber open at the front and
I cast or otherwise form the chamber within the body of the box or upon the
exterior at one side thereof whilst in some cases I form the chamber separate from
the box and embed it in the wall or building at one side of the letter box.

Improvements in or connected with Pillar or Wall Letter Boxes, and
in the Method of Attaching thereto and to Walls or Buildings
Coin Operating or Automatic Delivery Machines.
I JOSEPH FRAZER of 22 Croxted Road West Dulwich in the County of
Surrey but formerly of 57 Holborn Viaduct in the County of Middlesex
Merchant 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 my invention is to enable coin operating or automatic delivery
machines employed for the distribution of postage stamps to be securely attached
to pillar and wall letter boxes and to walls or buildings in such manner that they
will not project therefrom whilst they will be easily removeable without disturbance
to the pillar or wall letter box or wall or building.
For this purpose I cast or otherwise form the pillar letter box with a recess or
chamber in the side or front thereof in such manner that it does not communicate
with the interior of the letter box and I form the recess or chamber open at the
top and with flanges at the front to enable the automatic delivery machine to be
slidden into position therein or I form it closed at the top and introduce the machine
at the open front thereof and I fix the machine in position by means of a screw or

Figure 14 is a horizontal section of a separate case or chamber embedded in a
wall and having an automatic delivery machine attached thereto according to my

In the several figures like parts are indicated by similar letters of reference.
Referring to Figures 1 to 7 a represents a pillar letter box of the well known
external form and a* represents the wall of a recess or chamber a* which is formed
open or partially open at the front and within which is placed an automatic
delivery machine b.
The wall a* of the recess or chamber a* is cast in one with the pillar letter
box a or it might be otherwise fixed thereto in such manner that the recess or
chamber alies within the pillar a but does not communicate with the interior
thereof.
The wall a¹ of the recess or chamber a* is continued down to the floor a¹ of the
pillar box a and an opening is formed in the floor a¹ within the area of the recess or
chamber a to permit the lower end of the automatic machine b to extend there-
through and rest upon a bracket or support a fixed to the interior of the base a²
of the pillar box a.
At the sides and back of the recess or chamber a* the wall a*1 is carried
to the top a³ of the pillar box a so as to leave the chamber a* open at the top in
order that the automatic delivery machine may be slidden into position therein
and at the open front of the chamber or recess a* flanges a** are formed which
securely retain the automatic machine bin position whilst leaving its front exposed
to view.
As an additional security against the unauthorized removal of the automatic
machine 6 screws 6* are provided which pass through the back or it might be the

page_text: side thereof and screw into tapped holes formed in the wall a*1 of the chamber or
recess a and these screws are accessible only when the front door of the
automatic machine b is unlocked presumably by an authorized person.
The automatic delivery machine may extend to the top a³ of the pillar box a
as represented at Figures 1, 2 and 3 the upper part 6*1 thereof being shaped to the
form of the upper part as of the pillar box a so as to complete the outline thereof
or the automatic delivery machine b may terminate at the dotted line 6** in which
case a filling piece of the shape of the upper part 6*1 is employed to fit into
the upper part of the chamber or recess a* and complete the outline of the pillar
box a.
In order to prevent rain or other water finding its way in between the automatic
machine and the wall a* of the chamber a* and to give a finish to the pillar box
a cap or cover c is employed which is shaped to the top of the pillar box « and
secured thereto by screws c¹.
In the example given at Figures 8, 9 and 10 the chamber or recess a* is formed
closed at the top and of the same or approximately of the same length as the
automatic machine whilst the flanges a** are dispensed with leaving the chamber
or recess a entirely open at the front in such manner that the automatic delivery
machine may be introduced through such open front screws 6* being employed to
fix it in position in a similar manner to that described with respect to Figures 1
to 7 and as the chamber or recess a* is not continued through the top as of the
pillar box the cap or cover c and the filling piece *¹ are rendered unnecessary and
are therefore dispensed with.
In the foregoing examples I have not thought it necessary to show the internal
fittings of a pillar letter box and such as the hinged basket for receiving the letters
as it will be understood without illustration that such parts will require to be shaped
in such manner as to allow of the internal projection of the wall a* of the chamber
or recess a*.
In the example given at Figure 11 which represents the invention applied to a
projecting wall letter box the chamber or recess a* is formed in the side of the wall
box a and closed at the top in a similar manner to that described with respect to
Figures 8, 9 and 10 so that the automatic machine 6 can be inserted into the
chamber or recess a* from the front thereof or if desired the chamber or recess a*
may be constructed in a similar manner to that described with respect to
Figures 1 to 7.
In the example given at Figures 12 and 13 which represents an embedded wall
letter box having the invention applied thereto the wall a* of the chamber or
recess ais cast upon the exterior at one side of the letter box a so as to form the
chamber or recess a with an open front to receive the automatic machine >> in
the manner described with respect to Figures 8, 9 and 10 the means of fixing
the machine 6 in position being the same.
In the example given at Figure 14 a case a*1 constituting a chamber or recess
for the reception of an automatic machine is adapted to be embedded in a wall
independently of a wall letter box and for this purpose it is formed at the back or
it might be in other suitable position with laterally projecting flanges a** by the
aid of which it may be permanently bricked in position whilst the means of
fixing the automatic machine 6 in position therein are similar to those described
with respect to Figures 8, 9, and 10.
In the examples herein before given I have merely shown the case of an automatic
machine with the mechanism removed in order to illustrate my invention, and for
this purpose
I have selected a form of machine that is now in practical operation
being experimentally attached to a number of pillar letter boxes but upon the
exterior thereof so as to project therefrom.
This projection of the machine is for various reasons considered to be an
objectionable feature of the scheme and furthermore projecting machines cannot be
attached to pillar letter boxes in as secure a manner as is desirable.
By means of my invention however I remove all of these objections as by embedding

page_text: the automatic machine in the pillar or wall letter box I preserve the outline thereof
and attach the automatic machine thereto in such manner that it is difficult or
impossible to introduce a tool between it and the letter box so as to forcibly remove
it therefrom whilst at the same time it is easily removeable by authorized persons
without disturbance to the pillar or wall letter box or wall or building and when
in position is better protected from the influence of the weather.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A pillar er wall letter box formed with a chamber or recess therein or thereon
but integral therewith and isolated from the interior thereof but open at the front
substantially as herein shown and described and for the purpose stated.
2. A pillar or wall letter box formed with a chamber or recess therein or thereon
but integral therewith and isolated from the interior thereof but open at the front
and top and provided with flanges bordering such opening substantially as herein
shown and described and for the purpose stated.
3. In a pillar or wall letter box or wall or building a receptacle for an automatic
delivery machine consisting of a case or chamber recessed therein substantially as
herein shown and described.
4. The method of removeably attaching automatic delivery machines to pillar and
wall letter boxes and walls or buildings consisting in forming or fixing a recessed
case or chamber therein or thereon placing the automatic machine therein and there
fixing it substantially as herein shown and described.
