PROVISIONAL SPECIFICATION.
Improvements in or relating to Postal Transmission-apparatus, and
Motors therefor.
We, IVAN CIZEK and LUDWIG MAIZNER Konigl, Weinberge near Prague, in
the Empire of Austria, hereby declare the nature of this invention to be as
follows:-
This invention relates to a postal apparatus particularly suitable for domestic
use and operated by mechanical means for the delivery of various articles of small
size such as letters, newspapers, books and the like, from the ground-floor of a
house for instance, to any particular storey or floor and any particular residence
therein; or, into any separate box, compartment or shelf arranged on any
particular floor or storey in the building, each box or other division belonging or
being appropriated to any particular residence or flat therein, and all such boxes or
compartments on any one floor or storey being enclosed in a general case, under
lock and key. Obviously this invention is not limited to application to a single
house.
A movable and adjustable speaking-tube, fitted up in connection with each such
house-post enables verbal communication to take place between a person or
messenger e.g. a postman, at the mouth of the speaking tube, on the ground-floor,
and any person, servant or representative of the addressee, in any residential
chambers or flats on any one of the different floors of the house in question.
The delivery of any dispatch to any flat or residential chambers in a building
takes place by means of a transporter, which is moved up and down in a tube, in
the following manner.
In the ground-floor, either within the house or in the court, is fixed a box,
containing a chain wheel or pulley, carried in bearings and set in motion by a hand-
crank or by a motor hereafter to be described. By this chain-wheel or pulley
is driven a wheel secured to a shaft on which is mounted a toothed chain-wheel, of
the following construction;-
The toothed chain-wheel is held by friction only between a pair of smaller discs,
which are both prolonged by concentric sleeves, which are keyed with a feather
key. One sleeve is provided with a screw-thread at its inner end on which a disc
is screwed. A strong coiled spring, situated between the discs, presses one of the
discs against the chain-wheel, thus creating sufficient friction to be available for
the upward delivery of the transporter with its contents; but that friction must
not be greater than the safe load of the chain, so that the latter may not be
ruptured, in case the transporter encounters some obstacle in its ascent or descent
(as eg. if it reaches the top while the motor crank-handle, is still rotated) so
that in such a case the chain-wheel can remain at rest between the two rotating
discs.
The transporter is secured to the chain passing round the chain-wheel aforesaid
and which also, in its upper part, may be replaced by a wire-cord and passed over
a roller at the top; and this fastening is fixed to one side of the transporter and
operated by knobs. The transporter moves inside the transport-tube, by the side
of which are arranged other tubes, in one of which, the chain is led back to the
chain-wheel from the said roller; this part of the chain is provided with a
counterpoise weight to facilitate the upward delivery of the transporter..

page_text: The objects to be delivered upstairs are first introduced, downstairs into the
transporter, inside the transport tube, through an aperture, and thereupon, after
the suitable adjustment of the tilting mechanism, as hereinafter described the
handle of the crank (or the motor) is set in motion and the transporter is duly
dispatched.
The transporter consists of a frame with two bottoms, whereof the one is
horizontally and the other obliquely, placed. In this frame is rotatably fitted a
sheet-metal casing open at bottom as well as at the upper side, so as to turn upon
an eccentric bolt; and the lower edges of the casing are so cut that in their normal
position the casing is completely closed by the oblique bottom of the frame, so as
to retain the objects cast in to the same. In its upper front part the casing has a
projecting lip below an opening. After the casing is rotatably lodged in the
frame, it can be tilted out of the normal vertical position into an oblique position,
when necessary, and in that case all the objects contained in it are free to fall
out, and so much the more readily as this movement is facilitated by the obliquity
of the bottom.
The return of the said sheet-metal case to its original position is brought about
by the action of a spring, which is coiled round a piece of wire and compressed by
the action of tilting the sleeve.
The latter action takes place in a particular storey and in a particular section or
compartment of the delivery-box, in accordance with the arrangement or setting of
the tilting-mechanism.
There are as many separate tilting devices as there are floors or storeys in the
house or mansion under consideration and they are all secured to a cord one above
the other and adjustable in a tube. They are all alike in construction; each
consists of a frame fastened to the cord, and fitted with a metal picce rotating or
pivoting on a pin or bolt; this piece carries a projecting striker supported by a
roof-shaped sheet-metal piece or rib, from above, and another, from below.
A plate-spring exercises a constant outward or forward pressure on the said metal
piece, so that when tilting apparatus comes opposite an opening in the pipe, i.e. in
such pipe and in the transport-tube, the plate-spring has the effect of thrusting the
projection forward into the transport tube, while in the opposite case the said
projection is withdrawn therefrom, by reason of the slanting arrangement of the
roof-shaped parts which, sliding on the top and bottom edges of the said opening,
press against the piece-i.e. the sheet-metal piece on the upward, and the lower rib
on the downward travel of the tilting apparatus.
If now, one of these latter is so arranged and adjusted, that its projecting striker
advances into the transport-tube at the proper moment, then the tilting of the
sheet-metal-sleeve of the transporter will thereby be subsequently effected in due
course; inasmuch as, in the ascent of the said transporter, its projection comes into
contact with the striker of the tilting apparatus, and it will easily be seen that
the sheet-metal casing will be thereby tilted, and any object therein deposited will
at once fall out.
Inasmuch as the box of drawers or other compartments (belonging, one to each
of the flats or residential chambers on that flat) are suitably arranged, in front of
the transport-tube, opposite the openings between the pipe and the transport-tube,
the tilting action, being only capable of taking place opposite to one such com-
partment, the object or article thus discharged (as previously described) from
the transport-apparatus, must drop in one or the other of such compartments as
required.
The box of drawers or compartments itself consists of a fixed case, divided into
as many subdivisions, drawers or compartments as there are distinct dwellings on
the floor or storey in question. Each compartment is locked in front and is only
accessible to its owner. The sloping upper parts of the partitions between the
compartments are made to pivot upwards on a hinge, so that when the tilting
apparatus comes into action and the sheet-metal casing is pushed forward, the
upper partition, of the particular compartment in question, is always the one to be

page_text: turned or lifted up, and more room is thus afforded for the delivery of the letter,
parcel, or other article dropped out of the casing of the transporter.
For the reception of larger articles, for which there would be no room in one of
the small compartments, a catch-basket is arranged in proximity to them.
At the top of each floor or storey there is a tilting apparatus in the pipe and all
these are secured to a cord at intervals which do not agree with the heights of the
floors.
The openings of the separate storeys are equi listant from one another, while each
pair of tilting mechanisms are nearer to each other, in succession by the height of
a single opening.
as
In this manner one is enabled, at pleasure, to arrange the apparatus in such way
as to tilt the transport-casing at the level of any particular floor inasmuch
only one projecting striker is advanced into the transport-tube at one particular
time.
The arrangement for working the tilting devices up and down consists of a
chain-wheel by which another chain-wheel is driven; the latter is connected by its
shaft or spindle with a third chain-wheel over which the chain passes from the
main pipe and from another (downfall) pipe and, in the upper part, is replaced by
a cord on which are suspended the tilting devices. This cord for the tilting devices
is led over a roller at the top.
In order to bring about the working of the tilting devices with precision, and to
maintain the same in certain fixed positions, a stationary disc is provided,
having a number of equidistant holes into which the crank of the first chain-wheel
catches.
The handle of this crank is hollow and movable. In the hollow of the handle
there is a pin secured to the crank, while the handle is constantly pressed against
the stationary disc by means of a coiled spring. In the handle is a groove or slot
encircling the pin. The separate holes correspond to the separate compartments in
the box of drawers or the like, and when the handle-crank is fixed in any one
of the holes, the tilting of the transport sleeve or cage into one of the said
compartments results.
The withdrawal of the hollow handle from any particular hole is effected by
laying the thumb on the pin and, by passing the finger round the handle, this may
then be lifted out of the hole.
For the purpose of knowing in which compartment and on which floor the
delivery is to be made, an index is arranged in front of the transport-pipe, and the
said index is movable in a groove, by means of the working of a chain-wheel with
the aid of an endless cord passing over rollers; and, indeed, the displacement from
one flat to another corresponds to the rotation of the crank-handle from one hole to
another.
For the convenience of the house-residents a letter-box accessible, say, to the
postman, is provided on a pipe, on the ground-floor, for the delivery of small
articles, such as letters and the like, from the upper floors, such articles being
simply dropped into the pipe.
This letter-box is fitted with an intercepting valve or flap which guides into the
box any letter or similar small article dropped into the pipes, on any of the upper
floors.
Should it be required, without ascending to one of the upper floors, to obtain
therefrom any forgotten, small article needed for use, as e.g. a key or the like, all
that is necessary will be to explain one's requirement, by the aid of the speaking
tube (hereinafter described), to any servant or other person in the flat or residential
chambers in question, whereupon, by means of a pull or check-string, the flap or
valve is pulled back from the intercepting position, across the pipe into the vertical
position, against the side of the pipe and thereby allows the falling object to pass
the letter-box and drop into the catch-basket. Then, on the pull or check-string
being released, the flap or valve falls back again, by its own weight, into its former
or intercepting position.

page_text: The speaking tube, brought down inside a pipe consists of a fixed pipe which, in
front, debouches in the transport-tube, and of a movable pipe, encircling and sliding
up and down on the fixed pipe with packing between the two.
The sliding of the movable pipe takes place at the same time as and to the same
extent as the displacement of the tilting apparatus above described, by means of
cords connected with the latter. The sliding pipe is provided with as many orifices
as there are floors or storeys in the building; and at each opening is arranged a
slide-piece which is pressed against the wall of the tube by the plate-spring. The
openings are, together with the tilting-devices, arranged at equal distances apart;
while pipes leading, through the wall of the tube, to the separate dwellings on each
floor are arranged at the same distance apart as the openings, i.e. as the several
compartments in the box of drawers or subdivisions belonging one to each of the
said dwellings on the same floor.
In this manner, communication by means of the speaking-pipe is at all times
open only to that particular upstairs dwelling, flat, or set of residential chambers,
for which the tilting apparatus is set, as shown by the index-finger already
described.
The mouthpieces of the various inlets or outlets of the speaking tube as well on
the ground-floor as in each different dwelling throughout the house, are covered
with stoppers fitted with suitable whistles, so that, by blowing in with compressed
air (e.g. by means of a force-pump) one can give the signal that a conversation is
necessary; as at the same time the whistle on the ground floor is always sounded,
as well as also the whistle attached to the outlet upstairs of any particular dwelling
with which it is desired to communicate. While such a conversation is being
carried on, the stopper with the whistle must naturally be removed from the
mouthpiece at each end.
For the upward transmission of the transporter may conveniently be employed a
motor set in action by the pressure of water from any suitable source of water
supply. The form of construction of such a motor is preferably such as is adopted
and recommended by the inventor. This motor is mounted close by the chain
wheel on the axis or spindle thereof. It consists of a disc in which three pistons
are so arranged as to slide in and out; and which is surrounded by an eccentric
casing or jacket.
In this jacket are inserted two flat rings provided with concentric grooves in
which engage the studs or pins of the pistons so that as the disc rotates, the pistons
are compulsorily caused to reciprocate. The grooves are so constructed that the
packing of the pistons and of the casing or jacket is only tight over a portion of
their movement so as to prevent back-pressure from the other two pistons.

The delivery of any dispatch to any flat or residential chambers in a building
takes place by means of a transporter, which is moved up and down in a tube, in a
manner which we will first describe with reference to Figures 1 to 27:
-
On the ground floor, either within the house or in the court, is fixed a box,
containing a chain wheel or pulley a (Figures 6 and 7), carried in bearings and set
in motion by a hand-crank or by a motor hereafter to be described. By this
chain-wheel or pulley a is driven a wheel a, secured to a shaft a, on which is
mounted a toothed chain-wheel device A of the following construction (see
Figure 9):-
The toothed chain-wheel is held by friction only between a pair of smaller
discs b¹ which are both prolonged by concentric sleeves b₁₁ b', which are keyed
2

page_text: together with a feather key. One sleeve b¹ is provided with a screw-thread at
one end on which a disc b4 is screwed. A strong coiled spring c situated between
the discs b, and b presses one of the discs b, against the chain-wheel b thus creating
sufficient friction between the chain wheel and driving-devices hereinafter
described to make the chain-wheel available for the upward delivery of the
transporter with its contents; but that friction must not be greater than the safe
load of the chain, so that the latter may not be ruptured, in case the transporter
encounters some obstacle in its ascent or descent (as e.g., if it reaches the top while
the motor crank-handle a, is still being rotated) so that in such a case the chain-
wheel can remain at rest between the two rotating discs by b₂.
The transporter B (Figures 13 to 16) is secured to the chains d passing round
the chain-wheel 6 aforesaid, which chain in its upper part, may be replaced by a
wire-cord passed over a roller d₁ at the top of the transport-tube; and this wire is
fixed to one side of the transporter by attachments d₁. The transporter moves
inside the transport-tube C by the side of which are arranged other tubes, in one
of which D the chain d is led back to the chain-wheel device A from the roller d₁ ;
this part of the chain is provided with a counterpoise weight e to facilitate the
upward movement of the transporter.
The objects to be delivered upstairs are first introduced downstairs into the
transporter B inside the transport-tube C through an aperture ƒ (Figure 1) in the
latter and thereupon, after the suitable adjustment of the tilting mechanism, as
hereinafter described, the handle of the crank (or the motor) is set in motion and
the transporter is duly dispatched.
The transporter conists of a frame g with two bottoms 91 92 whereof the one gi is
horizontally, and the other g2 obliquely placed. In this frame is rotatably fitted a
sheet-metal casing hopen at bottom as well as at the upper side, so as to turn
upon an eccentric bolt g,; and the lower edges of the casing hare so cut that in
their normal position the casing is completely closed by the oblique bottom g, of
the frame, so as to retain the objects placed in the same. In its upper front part
the casing has a projecting lip ha below an opening 2. After the casing his
pivotally lodged in the frame g it can be tilted out of the normal vertical position
into an oblique position, when necessary, and in that case all the objects contained
in it are free to fall out, and so much the more readily as this movement is
facilitated by the obliquity of the bottom g
The return of the said sheet-metal case to its original position is brought about
by the action of a spring, which is coiled round a rod (Figure 15), h, and
compressed by the action of tilting the case h.
The latter action takes place at a particular storey of the house and effects
delivery into a particular section or compartment of the delivery-box, in accordance
with the arrangement or setting of the tilting mechanism.
There are as many separate devices to tilt the cases h as there are floors or storeys
in the house under consideration; and they are all secured to a cord one above the
other and adjustable in a tube E (Figures and 22). They are all alike in
construction; each consists of a frame i (Figures 17, to 19) fastened to the cord
and fitted with a metal piece i, rotating or pivoting on a pin or bolt ; this piece i
carries a projecting striker i supported by a roof-shaped sheet-metal piece or rib i
from above, and another is from below. A plate-spring i exercises a constant
outward or forward pressure on the said metal piece i₁ so that when the tilting
apparatus comes opposite an opening in the pipe E i.e. an opening O in such pipe
and in the transport-tube, the plate-spring i has the effect of thrusting the
projection i, forward into the transport tube, whilst between the openings Othe
said projection is is withdrawn therefrom, by reason of the slanting arrangement of
the roof-shaped parts i, and is which sliding on the top and bottom edges of the
said openings, press against the piece i-i.e., the sheet-metal piece on the upward
and the lower rib i, on the downward travel of the tilting apparatus.
If, now, one of these latter is so arranged and adjusted, that its projecting
striker i advances into the transport-tube at the proper moment, then the tilting.

page_text: of the sheet-metal-sleeve h of the transporter will thereby be subsequently effected
in due course; inasmuch as, in the ascent of the said transporter, its projection h₂
comes into contact with the striker of the tilting apparatus, and it will easily be
seen that the sheet-metal casing will be thereby tilted in the manner indicated in
Figure 10, and any object therein deposited will at once fall out.
Inasmuch as the box of drawers or other compartments (belonging one to each
of the flats or residential chambers on a flat) are suitably arranged, in front of
the transport tube, opposite the openings O between the pipe and the transport-
tube, the tilting action, being only capable of taking place opposite to one such
compartment, the object or article thus discharged (as previously described) from
the transport-apparatus, must drop in one or the other of such compartments as
required.
The box of drawers or compartments (Figures 10, 11 and 12) itself consists of a
fixed case, divided into as many subdivisions, drawers or compartments as there
are distinct dwellings on the floor or storey in question. Each compartment is
locked in front and is only accessible to its owner. The sloping upper parts of the
partitions between the compartments are made to pivot upwards on a hinge j, so
that when the tilting apparatus comes into action and the sheet-metal casing his
pushed forward, the upper partition of the particular compartment in question is
always the one to be turned or lifted up, and more room is thus afforded for the
delivery of the letter, parcel, or other article dropped out of the casing / of the
transporter (Figure 10).
For the reception of larger articles, for which there would be no room in one of
the small compartments, a catch-baskets is arranged in proximity to them as shown
in Figure 12.
At the top of each floor or storey there is a tilting apparatus in the pipe and all
these are secured to a cord at intervals which do not agree with the heights of the
floors (see Figure 7).
The openings O of the separate storeys are equi-distant from one another, while
each pair of tilting mechanisms are nearer to each other, in succession by the
height of a single opening O.
In Figure 22 e.g., is shown the arrangements of the tilting apparatus for a three-
storied house. In this view is shown the tilting-device set for action at the
2nd floor and in the lowest of the compartments of the series appropriated to that
floor. The tilting-device for the 1st. floor is seen already lifted beyond the
opening; while that for the 3rd floor has not yet attained the opening O by a
distance equal to the height of the said opening.
In this manner one is enabled, at pleasure, to arrange the apparatus in such
way as to tilt the transport casing at the level of any particular floor, inasmuch
as only one projecting striker 3 is advanced into the transport-tube at one
particular time.
The arrangement for working the tilting devices up and down consists of a
chain-wheel by which another chain-wheel k₁ is driven; the latter is connected
by its shaft or spindle with a third chain-wheel k₂ over which last the chain
passes from the main tube E and from another (downfall) pipe F and in the upper
part, is replaced by a cord is on which are suspended the tilting devices. This
cord for the tilting devices is led over a roller k3 at the top of the transport
apparatus.
In order to bring about the working of the tilting devices with precision, and to
maintain the same in certain fixed positions, a stationary disc is provided, having
a number of equidistant holes, with which (Figure 21) the handle of the crank,
of the first chain-wheel k engages.
In the handle is a
This handle is hollow and movable. In the hollow of the handle there is a pin
secured to the crank by means of the pin l, while the handle is constantly pressed
against the stationary disc by means of a coiled spring 15.
groove or slot, through which the pin l, passes. The separate holes ₁ correspond
to the separate compartments in the box of drawers or the like, on any floor and

page_text: when the crank handle is engaged in any one of the holes the tilting of the
transport-sleeve or cage h, into one of the said compartments results. The with-
drawal of the hollow handle from any particular hole 1, is effected by laying the
thumb on the pin and by passing the finger round the handle which may then be
lifted out of the hole l₁.
For the purpose of indicating in which compartiment and on which floor the
delivery is to be made an index m is arranged in front of the transport-tube and
the said index m is movable in a groove, by means of the working of a chain-
wheel m₁ on the same spindle as the chain-wheel with the aid of an endless cord
passing over rollers m₁ m3 m m m. m,; and. indeed the displacement from one
flat to another corresponds to the rotation of the crank-handle / from one hole to
another.
For the convenience of the bouse-residents a letter-box n (Figures 5 and 20)
accessible, say, to the postman, is provided on a pipe G ou the ground-floor, for
the delivery of small articles, such as letters and the like, from the upper floors;
such articles being simply dropped into the pipes.
This letter-box is fitted with an intercepting valve or flap n, which guides into
the box n any letter or similar small article dropped into the pipes, on any of
the upper floors.
Should it be required, without ascending to one of the upper floors, to obtain
therefrom any forgotten small article, needed for use, as e.g. a key or the like,
all that is necessary will be to explain one's requirement, by the aid of the
speaking tube (hereinafter described) to any servant or other person in the flat
or residential chambers in question, whereupon, by means of a pull or check-
string o (Figure 20) the flap or valve n, is pulled back from the intercepting
position, across the pipe G, into the vertical position, against the side of the
pipe, (see Figure 20) and thereby allows the falling object to pass the letter-box
and drop into the catch-basket o₁. Then, on the pull or check-string o being
released, the flap or valve ni falls back again, by its own weight, into its former
or intercepting position.
The speaking tube, brought down inside a pipe H is represented in Figure 25.
It consists of a fixed pipe p which has openings at intervals, along one side and
of a movable pipe p₁ encircling and sliding up and down on the fixed pipe p
with packing between the two.
The sliding of the movable pipe p₁ takes place at the same time as, and to the
same extent as, the displacement of the tilting apparatus above described, by
means of cords pa connected with the cord . The sliding pipe p₁ is provided
with as many orifices 3 as there are floors or storeys in the building; and at
each opening pз is arranged a slide-piece 4 which is pressed against the wall of the
tube H by the plate-spring ps. The openings p, together with the tilting-devices
are arranged at equal distances apart differing however from the distances between
the openings O; while groups of pipes pe leading, through the wall of the tube H
to the separate dwellings on each floor, are arranged at the same distance apart as
the openings O and individual pipes in a group are a distance apart which is the
same as the distance between the compartments in the box of drawers or subdivisions
on the same floor.
In this manner, communication by means of the speaking pipe is at all times
open only to that particular upstairs dwelling, flat, or set of residential chambers,
for which the tilting apparatus is set, as shown by the index-finger m already
described.
'
The mouth-pieces, of the various inlets or outlets of the speaking-tube, as well
on the ground-floor as in each different dwelling throughout the house, are
covered with stoppers fitted with suitable whistles, so that, by blowing in with
compressed air (e.g., by means of a force-pump) one can give the signal that a
conversation is desired. At the same time the whistle on the ground-floor is
always sounded, as well as also the whistle attached to the outlet upstairs of any
particular dwelling with which it is desired to communicate. While such
13

page_text: conversation is being carried on, the stopper with the whistle must naturally be
removed from the mouth-piece at each end.
For the upward transmission of the transporter B we may conveniently employ
a motor set in action by the pressure of water from any suitable source of supply.
The form of construction of such a motor as represented in Figures 26, and 27, is
preferably such as is adopted and recommended by the inventors. This motor is
mounted close by the chain-wheel a on the axis or spindle thereof. It consists of
a disc q in which three pistons g, are so arranged as to slide in and out; and which
is surrounded by an eccentric casing or jacket 92-
In this jacket 2 are inserted two flat rings 5% provided with concentric
grooves 93 94 in which engage studs or pins 9, provided on the pistons 9, so that as
the disc y rotates, the pistons are caused to reciprocate. The grooves 93 and
94
are so constructed that the pistons fit tight against the casing for only a portion of
their movement so as to prevent back-pressure from being effective on the other
two pistons which for the time being are not between X and Y.
The admission of the pressure water is at 7 and it escapes at ri
The hereinbefore described "bhouse-post" is susceptible of various constructive
modifications in its separate parts.
Thus the forwarding of objects may be successively effected in the manner
and by the apparatus which we will now describe with reference to Figures 28
to 50.
On the ground-floor the articles to be distributed are slipped into a transporter
contained in a transport-tube. This transporter contains, in this example, divisions
in just such number as there are receiving boxes on all the floors overhead; and
inasmuch as each such compartment is provided with a corresponding sign or mark,
so as to distinguish it, each article can readily be placed in the proper compartment,
belonging to the flat or residence, corresponding to the address placed on the said
article.
As soon as all the divisions of the transporter are charged or loaded, i.e., when
the whole postal or other delivery is distributed therein according to the addresses
the adjustable appliances hereinafter described are set for delivery on the first
floor.
When such a device has been fitted up, that, simultaneously with such adjust-
ment, the mechanism actuating the transporter is set in motion, the latter is sent
upwards, at once to its destination.
Arrived at the 1st floor it is there detained; the objects intended for the first
floor are duly delivered, and simultaneously, the apparatus for moving the
transporter is detached, and returns to the ground floor.
Then the apparatus for transmitting the transporter, still further, to the next
higher floor is connected, whereupon the above movements and processes are
repeated, and so on until the top floor is reached.
The upward delivery of the transporter is effected by means of a water wheel a¹
(Figure 33). This wheel is lodged in bearings in a casing a¹, (Figures 28, 29 33)
and is set in motion by means of a jet of water issuing from the mouth a', of a pipe
supplying water under pressure, which jet strikes upon the blades or buckets of the
waterwheel so as to cause rotation. The manner in which the admission of water
and its removal are effected, will hereinafter be fully explained, in connection with
the description of the admission-cock.
2
Firmly secured to the water-wheel a¹, is a toothed wheel which engages with
a second toothed-wheel ₁ (Figures 28 and 29). This latter is secured to a cord-
pulley over which an endless cord (or gut-band) b', passes, which, at the upper
end of the transport-tube, passes over a roller b¹ (Figure 284). By means of this
cord b' the transporter A therewith connected is moved to and fro vertically.
The counterpoise c' of the transporter A¹ slightly exceeds the weight of the
latter. By setting the water-wheel in motion, the transporter A is moved
upwards.
"
But in order to avoid any cessation in the functions of the " house-post (or

page_text: domestic automatic delivery apparatus) by reason of freezing of the water, or in
case of repairs having to be executed in the water-supply system, which might
temporarily require the cutting off of the water-supply the upward delivery of the
transporter can also be effected manually, by the aid of a hand-wheel'd' carrying
with it a chain-wheel d, from which, by means of an endless chain, the movement
is transmitted to the chain wheel d',, connected also with the cord or band pulley
or disc b¹.
The transporter A' (Figures 28 and 29) consists essentially of a frame A¹, in
which the partitions or compartments are firmly secured; of these latter the
bottoms do not lie horizontally, but rise steeply froin front to back. Above these
compartments or cases e¹ is attached to the frame A a basket A', which is pro-
vided for the upward delivery of articles of considerable size (such as packets,
books, parcels etc.).
In its upward and downward travel, the transporter is guided by the rollers f
which are guided by the rods or bars When eventually the lengthening of.
the transporting cord, band or wire comes about by the continual strain, the same
may be contracted or tightened up by the rotation. of the ratchet-wheel f', with
which engages a spring-controlled pawl f', in order to hold it in position; in such
case, the cord, band or wire is wound up on a bolt f1 (Figs. 28 and 29).
1
4
The rods or bars f, as well as those 1 (which serve in a similar way to support
or carry the counter-poise e', just as the bars f¹ do for the transporter itself) are
held in two frames B' whereof one is secured in the top, the other in the bottoin of
the transport tube (Figs. 31 and 32).
Letters and other objects to be delivered are introduced through the opening a
(Figs. 29 and 30) into the openings e₁₂ of the flaps e¹. This introduction (for the
distribution of the letters and parcels etc. as addressed) proceeds as follows;
The first or uppermost of the compartments el is first filled or charged;
then the transporter by means of the hand-wheel d', is raised through such distance,
as will bring the next division into position opposite the opening a i.e. so as to
charge or fill the second compartment, and so on in succession. Naturally the
flaps el are closed, so that the letters, when introduced may drop into the interior
of their respective compartments through the openings e. The flaps are each
marked with the name or number of the particular residence or flat indicated
and these marks are, of course, visible at the time of such distribution, so that
all errors may be avoided.
When all the compartments are filled in accordance with the addresses on the
letters or articles to be delivered, i.e. when all these objects have been placed in
their respective compartments, the adjustment is regulated for the first or lowest
floor; this being effected by turning the indicator finger g¹ (Figs. 28. 29. 30
and 48) from zero to I which numeral is (in Fig. 28) concealed by the finger g¹.
By the rotation of the indicator-finger g' the round rod which by means of the
tension-bar g', and lever 9'2 (Fig. 48) is connected with the indicator-finger g' is
rotated the rod carries on its lower end, rotatably attached to a boss, two stop
pawls 1, which by their weight and that of the rod ' somewhat reduced by the
action of the coiled spring above (Figs. 28 and 294) are caused to engage in the
teeth of a small ratchet-wheel. This small ratchet-wheel is prolonged downwards
in the form of a socket i containing a strong spiral spring, whereof one end is
secured to the said socket (or sleeve) and the other end is screwed to a cylinder ¿¹3.
This cylinder carries a bolt or stud 1, (Figures 34, 35, 36 and 37) which, by means
of a projection i¹, secured to the wall or casing of the transport-tube is prevented
from rotating and so causes the winding up of the coiled spring ¹. The socket or
sleeve is firmly secured to the rod which carries the admission-cock it, into
which the water enters at in order to enter the casing a¹ of the water wheel, by
means of the pipe i',. When the spiral spring i¹, is relaxed, the cock is closed;
when, by the above-named movement of the indicator-finger g', the rod h³ is caused
to rotate the stop-pawls engage in the ratchet wheel and turn it round,
whereby the spring ", is wound up, and the cock opened. The water, issuing
8

page_text: from a', (Figure 33) sets the waterwheel a' in motion and the transporter A¹
ascends.
On the rod ¹ are fixed projections ¹ (Figure 44) which by reason of the rotation
of the rod are brought into position; and indeed, at the first floor, by the
movement of the indicator finger g¹ the projections j¹ are set in such manner
that the transporter, when it arrives at them is at once arrested and held fast.
On the frame A', of the transporter (see Figure 41) there is arranged a sliding
piece, which is held in place by the spring k¹, coiled around the bolt ¹, and by
the projection k¹ secured to the frame A', and against which the spring, abuts
and is supported; while nevertheless, smaller movements, such as are permitted by
the elasticity of the coiled spring, are at the same time possible. A second
piece is firmly secured to the frame A.
In the piece is lodged a spring-catch k in which the upper projection ¹
(Figure 42) previously moved into position, rests. When, now, the transporter
attempts to rise above the first floor the top half of the spring k₂ is compressed and
the piece approaches the piece k¹. When the spring k¹, has been in this manner
sufficiently compressed it lifts the piece k¹ which then overcomes the natural weight
of the bar and slightly raises the same; and thereby the stop-pawls, at the
bottom of the rod h¹ are raised from the wheel and liberate the latter, which then
under the influence of the spiral spring, it returns to its normal position.
Thereby the admission cock is closed and the upward movement of the transporter
is arrested.
Simultaneously with this operation the upper end of the tongue ₁ assumes a
position under the action of the plate-spring L, (in which it is shown in Figure 43)
and is pressed by the same, so that its lower end is moved out and rests on the
projecting (Figure 43) so as to maintain the transporter at the first-floor level.
Simultaneously with the action here described the flaps e¹ of the compartments e¹2
belonging to the first floor, are opened, as follows:-
1
4
The rotating flaps e₁₁ are each pivoted to the transporter and connected with a
lever e's which levers are slotted at their ends, and have a bar or rod e¹ engaging
these slots (Figure 46). This bar or rod e¹ is surrounded by separate coiled
springs e¹ one end of each of which abuts upon a projection el connected to the
said bar or rode, while its other end rests on the adjacent levere's. If the rod e¹
is depressed, the springs e¹, are compressed against the levers e¹s which are thereby
caused to rotate, and thus bring about the opening movement of the flaps e₁₁ if
these are free to be opened; otherwise the springs remain in compression to a
greater extent, while the flaps remain closed.
It is to be remarked, that, when the transporter is held, as above described, the
piece is slightly depressed relatively to the piece l'. This piece ¹ carries a
projection m¹ which by this depression of ¹ comes into contact with a bell-crank
lever e¹, which is controlled by the spring e¹. Thereupon this bell-crank lever el,
is caused (by the projection m¹) to rotate, strikes against the end of the rod e¹
..which it depresses, so that the latter effects in the manner above described, the
opening of the flaps e, while the bolt-rod e¹, is previously withdrawn (Figure 47)
so as to liberate the rod e¹, so that the latter may be free to move (which it would
not otherwise be). For the bolt-rod e', thus fixing the rod e¹, thereby prevents
the opening of the flaps, so that in case an article of some weight is being conveyed
in any one of the compartments e¹ of the transporter, the flaps may not give way to
its weight; as these Haps cannot be opened until the bolt-rod e', is withdrawn,
which does not take place before the projection m¹ comes into collision, as above
described, with the lever e¹.
But. inasmuch as the lower flaps, belonging to the compartments whereof the
contents are to be delivered in the upper storey (or storeys) are prevented from
opening on the first floor, by a sheet m', which is secured to the transport-tube (and
is shown in dotted lines in Figure 47), it is only the upper part which can open at
this first stage; so that, finally, the contents of such compartments, as are
appropriated to the first floor only, (as illustrated in Figure 29) are there

page_text: discharged respectively into the separate compartments of the receptacle El
provided for them, on that first floor and whence they may be removed by
the respective tenants to whom the letters or articles may have been addressed.
After the distribution is completed for the first floor, the indicator-finger g¹ is
next turned to the number of the next following storey (i.e., to II.) Thereupon the
rod is rotated further, the stops or catches of the first storey are thereby thrown
out of engagement with the spring-catches k, and while the stop-pawls h₁ are
simultaneously thrown into gear with the ratchet-wheel and (the rod having
previously ie, immediately after the arrest and securing of the transporter,
dropped back into its former position, by its own weight) cause the said ratchet-
wheel to rotate; the admission cock is simultaneously opened, and the transporter
is immediately raised to the next floor.
By this rotation of the rod ' the stops or catches j of the 2nd Hoor (Figure 4+).
are brought into such a position that, on the arrival there of the transporter, they
arrest and secure the latter in the manner above-described for the first floor. The
arrest of the flow of water, the opening of the flaps, but only of those flaps belonging
to the compartments of the second floor, and the distribution of the articles, to be
there delivered as addressed, in the proper compartments of the receptacle on this.
floor take place, exactly as occurred on the first floor.
If the building contains any more floors, the transporter is constructed.
accordingly, as well as the stop catches j; the upward delivery of the transporter
is thus carried on, and its working repeated, as often as necessary until, finally all
the letters and other articles to be delivered have been distributed into all the
compartments of the receptacles on the different floors, in correct accordance with
the addresses respectively.
Thereupon, the indicator finger gl is returned to zero again. The pawls h¹, being
pressed upon by the plate-springs (Figure 34) the rod ¹ can be turned back
again into its original position, while the said pawls pass over the teeth of the
ratchet-wheel, without communicating rotary motion to the latter. Consequently.
the admission-cock remains closed.
The return-motion, i.e., descent of the transporter takes place then by its own
weight, as, when the rod ¹ is turned back into its original position, the stops or
catches are removed out of the path of the transporter, which is consequently.
freely suspended, and under the influence of the counter-balance.
The transporter does not move quickly, however, under the influence of gravity
inasmuch as the descent thereof not only sets in reverse motion the cord or band
pulley but also all the gear and the waterwheel and also the gear wheels b₁₁
and 6. The latter is connected with a regulator, which opposes the too rapid
descent of the transporter. This regulator (see Figures 38, 39 and 40) consists of.
two discs; one of these discs n¹ is firmly secured either to a fixed part of the
mechanism or to the transport-tube while the other disc n', rotates with the
wheel b i.e., with the water-wheel and is free to move endwise or axially and being
guided in such end wise movement by the lugs n', carried by the spindle of the
waterwheel. In the lugs n', are carried the arms n's provided with balls at their
outer ends, having their opposite ends shaped as cams n'. A spring n¹s unites the
two arms 3 together.
2
When the wheel-gear rotates too rapidly, the balls fly apart, so that the cams n¹,
press upon the fixed disc n' whereby the rotation of the wheel-gear and thus also of
the entire mechanism is retarded.
In this manner a too rapid upward or downward movement is prevented.
Arrived at the bottom the transporter is stopped by a projection q' Fig. 28 which
comes in contact with the rod k', while the spring 2 tempers the shock.
Articles of a considerable size must be put into the basket or receptacle A₁₂
attached to the transporter, through a door C' (Figures 29 and 30) and are drawn
out, at an upper floor, by an opening, above the ordinary receiving box or elsewhere,
specially provided for that purpose.
In order to enable the regulation of the apparatus and the upward delivery of

page_text: the transporter to be properly effected from any one of the corridors upstairs,. a
hell-crank lever o' (Figures 30 and 45) is arranged, beneath the receiving box of
each storey, in such manuer as to be rotatable; this lever by means of the rod o'
and of a lever o'₂ connected with the rod is so connected with the latter, that,
when the lever o¹ is rotated the said rod is also caused to rotate. A small
dial o' indicates how far the bell-crank lever o must be turned round in order to
produce the desired effect.
Obviously, the admission-cock must be so constructed as to admit of the adjusting
or setting-lever being turned, at once, and directly to the second or third, etc. floor, i.e.,
to II, III, IV, etc., so as to effect the upward delivery of the transporter at the
desired floor, without any stoppage at all at the first, or the first and second
floors etc., and so on to the top storey of all. The only effect upon the mechanism
itself is that the spring ¹ is wound up more for a continuous movement of the
transporter than in the usual way, when there are intermediate stoppages, and
deliveries of letters, parcels, books or other articles.
Letters and the like small articles, which one is not inclined to take downstairs
from an upper floor oneself (or in default of a servant or messenger) to any one
waiting for the same, on the ground floor may be dropped into the fixed rectangular
sheet-metal pipe D inside of the transporter-tube (Figures 31, 32, 49 and 50)
through a special opening provided in each storey for the purpose, so that they
may fall into a pivoted box D₁ (Figures 49 and 50) whence they may be easily
removed after the box has been swung opeu, as shown in Figure 50.
For the purpose of advising the delivery or distribution of any letters etc., to the
various addressees on the different floors, an electric-signal apparatus of any well-
known type is installed, in connection with the apparatus; and in order, eventually,
to enable verbal communications to be carried on between the parties, with reference
to such despatches, etc., between the ground-floor and the upper floors, a speaking
tube is also installed, as before, from the ground-floor with branches to all the
residential flats or other residences on the several floors, and having its lower
mouth-piece at p² (Figures 29 and 30); while the electric signalling apparatus is
used to give the first notification that such communication is wanted.
It is to be observed, in relation to the descent of the transporter, that one may
arrest it at any particular floor, if desired, for which, however only the catch kỉ
comes into operation and secures the transporter. The flaps e₁₁ are not opened in
this instance.
The manipulation of the upstairs distribution of articles, may also be lessened in
the following manner :-
In the manner above described, the letters newspapers, etc. to be distributed, are
. inserted in the said transporter; the indicator-finger g' is first turned to I for the
first storey and then, after a short time, to II for the second and so on, until the
last or highest storey is reached. Thereupon the indicator finger g' after a short
time is turned back to zero.
In case the water-supply pressure is not sufficiently high to enable it to elevate
the transporter by means of the waterwheel a¹ that object must be attained by
moving the transporter by the pressure of a water-column.
Such a device is illustrated in Figures 51 and 51 and in Figure 51B.
The counterpoise c¹ moves in a pipe s¹ into which, above the counterpoise, the
pipe s opens as a continuation or prolongation of the pipe ¹. The water from
the water-supply pipe enters, in the manner herein before described (by the opening
of the valve, Figure 36 by reason of the rotation of the rod ¹) into and through
the pipes, and s, and so into the pipe s fills the space above the counterpoise c¹
(notwithstanding that some of the water runs down past the counter-poise), so that,
by the pressure of the water-column above the weight or counterpoise c', the latter
is depressed and consequently the transporter is raised. The counterpoise c¹ is
fitted with scrapers or rubbers c₁₁ which keep the pipe clean and clear from any
dirt or deposit which might form or settle thereon. The pipe s', is arranged as an
overflow pipe, for the purpose in case the water column above the counterpoise c¹

page_text: should not suffice to depress c¹ of allowing the pressure water to run away and
escape underneath the weight c' through the said pipe s¹,.
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 :-
