According to this invention the ordinary dial and hands are dispensed with and
the hour and minutes are shown on a dial by means of the figures themselves.so
that at a glance the exact time to a minute will be seen on such dial. In order to
effect the above the dial has say three apertures therein one (say.at top) shewing:
the hour through same and the other two shewing the minutes. this I effect as
follows under the dial I suitably pivot 3 discs that to shew the hour having the
numerals 1 to 12 round, the surface of same, and the other two (which represent
the minutes) having the numerals from 1 to 6 and 0 to 9 respectively round their
surfaces the last mentioned disc is caused to revolve the distance of one numeral
by suitable mechanism each time the, "second" wheel makes one revolution and
when this disc has thus moved ten times it operates upon the disc, having the
numerals 1 to 6 by suitable means so as to move it round the distance .of.one
numeral and when this latter has moved 6.times it in its turn operates upon the
hour disc so as to move that, round the distance of one numeral. Each time any:
of the dials move round the consecutive numeral is brought opposite one of the
apertures thus shewing the time to a minute. By the addition of three more discs
operated upon at each revolution of the hour dial. I can shew the month and
date one of these latter discs having the month and the other two suitable numerals
thereon to shew the day of the month

"AN IMPROVED
According to this Invention the ordinary dial and hands are dispensed with and

surfaces the last mentioned disc is caused to revolve the distance of one numeral
by suitable mechanism each time the "second" wheel makes one revolution and
when this disc has thus moved ten times it operates upon the disc having the
numerals 0 to 5 by suitable means so as to move it round the distance of one
numeral and when this latter has moved times it in its turn operates upon the
hour disc so as to move that round the distance of one numeral. Each time any
- of the dials move round the consecutive numeral is brought opposite one of the
apertures thus shewing the time to a minute. By the addition of three more discs
operated upon at each revolution of the hour dial I can shew the month and date
one of these latter discs having the month and the other two suitable numerals

And in order to explain my said Invention more fully I will now proceed to
describe the same with reference to the accompanying drawing

DESCRIPTION OF THE DRAWING
Fig 1 shews the face or dial of a time-keeper constructed according to this
Invention
+

. Fig 2 shows the movement constructed on the usual principles (the balance
regulator and other parts well known not being shown) and adapted to this
Invention these parts are arranged on one side of the pillar plate. Fig 3 shows
the parts. of the movement on the opposite side of the pillar plate viz immediately
under-neath the dial. Fig 1 will be understood without further description. In
fig 2 a is the spring barrel and main wheel with 60 teeth together with the usual
wheels and pinions. b is a wheel having four teeth cut away at equal distances
there being 5 segments with 8 teeth each as shewn. The wheel b in its rotation
engages periodically with the pinion con the arbor of the "second" wheel which
is actuated in the usual way. The minute wheel n engages with pinion. o of
wheel b. On the same arbor as the wheel b is fixed the star wheel d (shewn dotted
at fig 3) having 5. teeth or arms this engages with the wheel e with 10 teeth (also
shewn dotted in this figure) fixed on the same arbor as the unit minute disc f with
numerals 0 to 9 inclusive this disc is kept in position by the pawl g as shewn.
The disc has one tooth h-i shews the decimal minute disc having numerals 0 to 5
inclusive with star wheel.p (shewn dotted) with six teeth or arms and one extra
tooth this latter engages with one of the 12 teeth of the wheel fixed on the
arbor of the hour disc m. This hour disc has numerals 1 to 12. The action is as
follows: Upon the pinion c of the "second" wheel arriving at one of the blank
portions of wheel b (which takes place at each revolution of such pinion) this

page_text: latter will be released and spring round to the next section with teeth which will
again immediately engage with the pinion c of the second wheel this action will
cause the star wheel d to rotate the disc f the distance of one tooth by the inter-
vention of the wheel e and consequently exhibit the following numeral through
the aperture in the dial and so on until it has made 10 changes or one revolution
of the discf the tooth h now engages with one of the teeth in the wheel p (shewn
dotted) causing such wheel to rotate one sixth of a revolution and exhibit the
following decimal and when this has completed one revolution i.e. changed. 6 times
the tooth k will engage with one of the teeth in the wheel and cause the hour
disc to rotate one twelfth of a revolution thereby exhibiting the following numeral
representing the hour. By this means the time will be seen on the dial as shewn
in Fig 1 without the use of hands. Having thus described the nature and object
of my said Invention and the means whereby the same may be carried into
practical effect I would remark in conclusion that I do not wish to limit myself to
the precise details herein described for actuating the indicating discs but what I
claim as my Invention and desire to secure by Letters Patent is A watch or other
timepiece substantially as set forth
In Witness whereof I the said Joseph Pallweber have hereunto set my
hand and seal this twenty sixth day of June in the year of our Lord
one thousand eight hundred and eighty three
