Improvements in Machines for Checking the Receipt of Moneys
in Shops and other Places.
I, GEORGE HENRY GLEDHILL, of Northgate, Halifax, Yorkshire, Milliner & Fancy
Draper, 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 :—
This invention has reference to prior Letters Patent granted to me, bearing date
the 11th day of August A.D. 1886, No. 10.247, but my new Invention is applicable
to any description of money checking machines where a sliding drawer is employed.
In money checking machines constructed according to my former Patent, certain
catches and wheels are employed, which were operated on the drawer being opened
so as to cause a piece of paper to travel under an aperture where the amount of
money last received had been registered. In practice I have found that the drawer,
after being partially closed, could be withdrawn again without operating the ratchet
wheels and paper, and this would permit a dishonest person to take money out of the
till after the purchaser had gone away. My invention consists in the adoption of
mechanism which will prevent the drawer, after being partially closed, from being
withdrawn, as was previously the case, the mechanism being of such a nature that the
drawer cannot be withdrawn until after it has been pushed quite "home," and
operated the catches & wheels to move the paper under the aperture; which, however,
simultaneously with the complete closing of the drawer, the mechanisin will be
released so that the drawer is free to open.
Such being the nature and object of my invention, I will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying sheets of
drawings illustrative thereof, wherein Fig. 1 is section of a money checking machine
having an arrangement of mechanism applied thereto for making the drawer self-
locking after having been once opened. The box is shewn at A provided with a lid B
and the aperture C through which the paper is exposed, and on which the amount of
money last received has been written down.
According to one method of adapting the drawer D for the purposes aforesaid,
I place on the upper edge thereof serrations or catchos as shewn at E, the back end of
the said drawer being provided with a pulley or other device F for purposes herein-

page_text: after explained. G is a bar capable of sliding backward and forward in brackets H
when actuated. 'Behind the sliding bar are three or other suitable number of
weighted swinging short lever arms J, which are capable of oscillating upon centres
attached to the inner. side of the box A and within slots or niches made at the back of
the said sliding bars as shewn in dotted lines: The sliding bar carries a light finger a,
which when the drawer is pushed home, the said light finger passes underneath a
catch b, which it lifts so as to keep it clear of the serrations. Fig. 1 shews the drawer
closed, in doing which the bowl F comes into contact with the cranked end c of the
sliding bar, pushing such sliding bar in the direction of the arrow in such manner as
to carry the light finger a underneath the catch b, as the drawing illustrates. When
the drawer is in this position. it is free. to be opened, in doing which the bowl F comes
into contact with the swinging arms J, but as these are swung upon centres which
allow of their free movement in one direction the bowl F passes under the said
swinging arius without operating the bar G, but if the drawer be opened as-shewn in
Fig. 2 and an attempt is made to close it, the bowl F will come into contact with one
or other of the swinging arms J in such manner as to act upon the bar G causing it
to slide in the direction of the arrow marked thereon, consequently the light finger a
will be removed or carried from underneath the catch b, whereupon the latter will
drop into the serrations E, and if after that moment the attendant desires to open the
drawer without registering, it will be impossible for him to do so, because the catch,
which has now entered the serrations, would prevent it. Therefore, before the drawer
can be again opened, it must be completely closed, so that the pulley F again strikes
the bent end of the sliding bar, so as to bring the bar back again and cause the
light finger a to lift the catch bout of gear with the ratchet teeth E.
In Fig. 3 I have shewn section of a modified arrangement of mechanism where
swinging arms K (attached to the vertical side of the box) are provided with a
knuckle joint d, which on the drawer being opened allows the pulley F to pass under
without operating the sliding bar, but on the door being closed, the pulley F would
strike the knuckle joint of the lever, which would now be rigid, consequently the
lever would oscillate and act upon the sliding bar as previously explained. This
arrangement may be varied by placing the levers K horizontal instead of vertical, but
flat springs would have to be used to force the joint d straight again.
By the employment of apparatus such as is herein shewn and described the drawer
of a money till cannot be opened after having once been partially shut; this therefore
ensures a registration taking place, and the newly recorded figures being moved past
the aperture in the lid of the box.
Having now particularly described and ascertained the nature of my said Invention,
and shewn how the same is to be performed, I would have it understood that 1 do not
confine myself to any particular form of mechanism for enabling the drawer to
perform the functions described, as other forms of mechanism may be employed to
effect the same purpose, but what I believe to be new and claim as my invention is :-
The application of mechanism to a drawer in a money checking machine, so that
when the drawer has been opened and afterwards partially closed, such drawer cannot
be withdrawn until after it has been completely closed, for the purposes substantially
as described, or any mere modification thereof."
