An Improved Check Till.
I, ANTON LUDWIG OLSEN of the City of Kopenhagen in the Kingdom of Denmark,
Wine 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 :-
My invention relates to an improved check till suitable for shops and the like and
the manner in which my invention is carried into effect is shewn in the accompanying
drawings of which
Fig. 1 is a side view and
Fig. 2 a front view of the improved check till according to my invention.
The apparatus works with two tapes of paper or other suitable material, which are
indicated on the drawings by the dotted lines and c' and which are rolled up on the
rollers E, F, which are likewise shewn by dotted lines. The check or control is
obtained thereby that the figure or mark of the operator is written upon the uppermost
tape such figure or mark being at the same time printed on the lower tape by means
of a coloured ribbon inserted between the two. The tapes are carried over the curved
plate G, between the rollers K which push them forward and at A. they pass directly
underneath an opening in the casing, thus laying the uppermost tape bare so that the
control figure can be written upon it, the same being impressed, by means of the
interposed coloured ribbon, upon the lower tape, which latter is thereupon carried
underneath a glass plate 6, and collected in compartment S', while the upper tape is
torn off by pressing it against a bar a (Fig. 2) and may be handed to the purchaser.
The mechanisms for carrying the tapes forward are as follows
-
The motions are obtained by pulling and pushing the drawer c. When the drawer
is pulled out from the position shewn in Fig. 1, then the spiral spring M pulls the
bar L', which turns on pin h, the rack L of the upper part of bar L' thereby turning
the tooth-wheel g, in which it is geared and which is fixed on piston d of roller K
(fig. 2), the latter being kept steady, while the wheel turns, by means of click-
wheel and pawl k. When subsequently the drawer is pushed inwards, then the
bar L which is fixed on the drawer will push against a pin on the bar L', thereby
carrying the latter to the position in Fig. 1, while the spiral spring M is strained.
Under this motion the tooth-wheel 'g is turned round and a pawl catching in the click-
wheel o, causes the roller K to follow the movement whereby the paper tapes are
.carried forward sufficiently for making the requisite check figures.
The payment made by a purchaser is placed upon a movable glass disc N', whence
the money falls down upon a movable plate R and thence into the receptacle N. This
double movement must happen in such a manner that the plate R is always emptied
before anything is thrown in from the glass disc N. To effect this a contrivance is
necessary for moving the metal plate R and which is constructed as follows:-
A bent angle-lever O P, movable on the pin O¹, reaches with its leg P up to under-
neath the plate R which is movable on bolt n. To the upper edge of drawer C, which
contains change-money, is fixed an upright bar g', on the upper ends of which is a
catch 9', which, when the drawer C is pulled out, pushes against the bent leg O of
the angle lever O P, which leg O it carries with it until it slides off at the end of it, the
leg P at the same time pushing against the bottom of plate R thereby tipping it so
that coins lying upon it fall into drawer N. As soon as the catch g'slides off the lever-
leg O, the lever of course again falls back to its original position as shewn in
the drawings. The catch g¹ is fixed in such a way that, when the drawer is pushed
back, and when it pushes against O, it can turn aside, a spring or other con-
trivance causing it to again take up its original position as shewn in the
drawing Fig. 1.
The contrivance for enabling the glass-plate N¹ to be moved consists of a bar C¹

page_text: which turns on bolt C1 (Figs. 1 & 2). The bar is connected with a rod m, the
opposite end of which is attached to the drawer C.
said bar is fixed a catch q" which, when the drawer from the pulled out position is
On the upper end of the
again pushed in, strikes against bar Q, turning on bolt s. The bar Q which is
pulled back by the spiral spring is connected with a similar bar at the opposite
side of the apparatus by means of a thin metal rod P¹, which carries the one side
of the hinged glass disc N¹. The rod P¹ moves in the notch S, whereby the glass
plate N is tilted in such a manner that coins placed upon it are thrown on the
plate R. The movement of this and of the glass plate N¹ thus takes place at
different times.
The mechanisms for working the colour transfer ribbon consist in the ribbon D,
which with the coloured side downwards, is moved, between the two paper tapes, shewn
in Fig. 1 from the end and in Fig. 2 from the side. It is endless and is carried over
the two rollers H, H, the axes of which are carried by brackets D'. The ribbon is
moved a step every time, the bar a is pressed down inasmuch as a pin b' which is
firmly connected with the said bar, is thereby caused to press against a swiper t, which
turns on the pin t. A pawl e connected with the swiper thereby moves a click-
wheel p fixed on the rollers piston so that the roller and ribbon is moved one tooth
forward. The swiper is again raised by means of a pin t" which is pushed upwards
by a spiral spring f.
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. An Improved check-till for shops and the like in which two tapes are employed
which by means of colour transfer ribbon interposed between them, receive simul-
taneously the check mark, one of the said tapes subsequently being collected in the
apparatus, while the other may be torn off, all substantially in the manner as and for
the purpose described.
2. In such check tills the mechanism for moving the paper tapes_consisting
essentially in the curved bar with rack L for moving the rollers K, between
which the paper tapes are conducted, and the spiral spring M and bar L" all
substantially in the manner as and for the purpose described and shewn in the
drawings.
3. In such check tills the mechanism for tilting the plate R consisting essentially
in the bent angle lever OP, actuated by an upright bar attached to drawer
substantially in the manner as and for the purpose described and as shewn in the
drawings.
4. In such check tills the mechanism for
the bars and C" actuated by connecting
substantially in the manner as and for the
drawings.

5. In such check tills the mechanism for moving the endless colour transfer ribbon DJ,
consisting of roller H, H', with click-wheel and pawl e, and the swiper t, which
is prossed down by the bar a and pulled back by spiral spring f, all substantially
in the manner as and for the purpose described and as shewn in the drawings.
