'IMPROVEMENTS
IN MACHINES FOR STAMPING LETTERS, POSTAL CARDS AND LIKE ARTICLES WITH
CANCELLING MArks, Dates or DEVICES, PARTLY APPLICABLE Also for Printing
FOR OTHER PURPOSES."
This Invention relates to improvements in machines by which the stamping of
letters, postal cards etc., at post offices i.e. the printing of the date and place of
reception and delivery thereon, and the cancelling of postage stamps may be
effected mechanically, but by which also any mark of recognition may be affixed
to tickets and similar objects or by which letter paper visiting cards etc. may be
provided with the required inscriptions.
The objects of my improvements are firstly to avoid, that more than one object
to be stamped may be brought at the same time to the stamping mechanism, and
secondly to regulate the position of the object to be stamped, while the mark
is attached thereon and thirdly to afford an elastic stamping.
I attain these objects in the following manner.
The letters etc. to be stamped are heaped near to a platform above which an
endless chain or band provided with flexible fingers runs over rollers driven by
band or power. These fingers catching the upper one of the letters etc. guides it
over a roller or a series of rollers which rotate in the direction opposite to the one
of the chain. To another roller to which an intermitting rotation is communicated
by means of a cut out disc. A fork connected with a lever is raised and lowered

page_text: froin and to the roller by means of a cam fixed to the shaft of the cut out disc, and
retains the letters etc. until the stamping dye has imprinted its mark thereon.
After stamping the letter etc. quits the machine in consequence of the combined
function of the roller and the full part of the cut out disc.
In combination with the grasping fingers the fork serves to bring the object to 5
be stamped in the right position for the application of the stamp, the finger pushing
the letter etc. until it touches with the required edge both arms of the fork.
The stamping die is mounted on a piston which slides inside of a block fixed to
the shaft of a disc; a cushion of rubber beneath the piston serves to give elasticity
to the die, during the impression. When the die is composed of types also a rubber 1
plate may be put under them for the same purpose and in order to equalize
differences in their length.

JOHANNES GEORG AUGUST HALLER of Hamburg Germany. "IMPROVEMENTS
IN MACHINES FOR STAMPING LETTERS POSTAL CARDS AND LIKE ARTICLES WITH
CANCELLING MARKS DATES OR DEVICES PARTLY APPLICABLE ALSO TO PRINTING
FOR OTHER PURPOSES."
This Invention relates to improvements in machines, by which the stamping of
letters, postal cards etc. at post offices, i.e. the printing of the date and place of
reception and delivery thereon, and the cancelling of postage stamps may be
effected mechanically, but by which also any mark of recognition may be affixed
to tickets and similar objects, or by which letter-paper, visiting-cards etc. may be
provided with the required inscriptions.
The objects of my improvements are first to avoid, that more than one object to
be stamped may be brought at the same time to the stamping mechanism; and
second to regulate the position of the object to be stamped, while the mark is
attached thereon, and third, to afford an elastic stamping.
I attain these objects by the mechanism illustrated in the accompanying Sheet
of Drawings in which Figure 1 is a vertical section of the entire machine; Figure 2
a front elevation thereof, partly in section; Figure 3 a side clevation; and Figure
a top view partly in section.
Similar letters refer to similar parts throughout the several views.
The letters etc. to be stamped are raised by the operator to the hinged plate b
provided at its under side with a rubber covering a. Here the upmost letter,
postal card etc. c is caught by one of the fingers of elastic material attached to
the endless chain d, which transports the letter etc. on the plate g to the roller f.
In order to avoid that more than one letter at onco is taken by the finger e, the
discs h, rotate în face of the plate b in a direction opposite to the direction of the
fingers e.
A further progress of the letter etc. on the roller fis hindered by the fork k of
the angle-lever-device k until the projecting part of the cut out disc p (of elastic
material, rubber etc.) touches the object to be stamped.
In this moment the arm l
has passed the highest point at the cam m and is now pressed backwards by the
spring I thus causing the fork to be raised. The rotating disc p, which in
consequence of the cut-out sections on two opposite sides did not touch the roller f,
so long the finger e was in contact with the letter etc., now gets hold of the letter
or postal card etc. c and advances it by aid of the roller ƒ in the proper position for
stamping. When the mark is imprinted the one full segment of the disc p has
passed the roller ƒ and transported the letter etc. c so far as to allow it to leave the
machine.
The disc p, the cam m the stamping-blocks with the two stamps n, the one
guiding-wheel t of the endless chain & and the geared or friction wheel r provided
with a belt-groove are fastened to the main shaft o, which is turned by means of
the crank-wheel q.
The wheel works the gear or friction roller of the inking-cylinder u, which
is filled with printing ink and covered by a jacket of felt or cloth u; the printing-
ink passes through a number of perforations in the cylinder u to the cover u'.
Every time after stamping a letter &c. the stamp n comes into contact with the
inking-cylinder in order to supply it with printing-ink. The bolts of the stamps n
slide like pistons inside the stamping blocks and are pressed outwards by rubber
cushions n². Also the types of the stamps are mounted on rubber pads n².

page_text: The belt-groove of the wheel r communicates by a rubber-belt with the pulley h¹,
which rotates the two or more discs . The second guiding wheel &¹ of tlie endless
chain d is fastened to the shaft o', which rotates loosely in its bearings w sliding
between rubber-buffers v.
Having thus fully described my Invention what I desire to claim and secure by
Letters Patent, is—
1. In machines for stamping letters etc. the combination of the elastic cut-out
disc p with the stamping-block s and the stamps n, substantially as set forth.
2. In machines for stamping letters etc. the combination of the cut-out disc p
with the cam m, the lever 1, the spring i, the fork k and the roller f, substantially
as specified.
3. In machines for stamping letters etc. the combination of the fork k with the
roller f, substantially as and for the purpose specified.
4. In machines for stamping letters etc. the combination of the discs h with the
fingers e, substantially as described.
In witness whereof I the said Johannes Georg August Haller have hereunto
set my hand and soal this Sixth day of August in the year of Lord One
thousand eight hundred and eighty two.
