I, GEORGE BARRON, of Tower House, Saint John's Road, in the County of London,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the combination of coin freed apparatus, with lever
weighing machines such as those known as Salter's hand lever weighing machines.
According to this invention I connect to the vertical rod that is attached to the
lever, a cord passing over a pulley, such cord having a weight attached thereto to
bring the said rod into position. I pivot a horizontal lever weighted at one end and
the other end is provided with a pocket for the reception of the coin.
A tooth is cut in the aforesaid rod into which tooth a pivotted pawl engages to
lock the said rod until a coin is inserted.
I provide suitable mechanism to release the coin as the party steps off the machine,
this may be done by means of a pin in the vertical rod, which pin tilts the aforesaid
horizontal lever back to its normal position.
The whole mechanism is placed in a suitable case provided with a coin slot.
Improvements in or relating to Coin-freed Weighing Apparatus.
I, GEORGE BARRON, of Tower House, Saint John's Road, in the County of London,
Manufacturer, 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 relates to the combination of coin-freed apparatus with lever
weighing machines such as those known as Salter's hand lever weighing machines.
According to this invention, I connect to the vertical rod that is attached to the
lever, a cord passing over a pulley, such cord having a weight attached thereto to
bring the said rod into position. I pivot a horizontal lever weighted at one end and
the other end is provided with a pocket for the reception of the coin.
A tooth is cut in the aforesaid rod into which tooth a pivoted pawl engages to
lock the said rod until a coin is inserted.

page_text: I provide suitable mechanism to release the coin as the party steps off the
machine this may be done by means of a pin in the vertical rod, which pin tilts the
aforesaid horizontal lever back to its normal position; or it may be effected in
the manner hereinafter described with reference to the drawing.
The whole mechanism is placed in a suitable case provided with the coin slot.
And in order that my invention may be better understood, I will now proceed
to describe the same with reference to the accompanying drawing, in which
Fig. 1 shows, in elevation, the mechanism comprised in my invention, and
Fig. 2 a plan of the coin-receptacle.
shows the vertical rod attached to the weighing lever. To this rod a is con-
nected a cord b, passing over pulleys and d, and having a weight e attached
thereto. f shows a horizontal lever weighted at g, and pivoted at 1: the other end
of this lever f carries the coin receptacle i. w shows a pin fixed to the back of the
rod a.
A notch is cut in the rod a at j. A pawl k, pivoted at m to a fixed bracket x,
engages in this notch.
The coin receptacle i is provided with an arm or stop y which prevents the coin
(indicated by dotted circle 2) from passing through. This arm y is fixed to a hollow
spindle t, and to the said hollow spindle is fixed a bent lever u resting upon a stop
'piece vas shown on the drawing: the spindle t forming the fulcrum of the lever u.
Another lever passes freely through the hollow spindle t, and rests upon the
lever u.
n, o and p show pins or screws against which the projecting end of the lever
the coin receptacle i strikes.
ก of
r is a quadrant for releasing the pawl k.
When the coin drops into the coin-receptacle i, the lever fis turned, the quadrant
causing the pawl to be released from the rod a, so that the weighing mechanism is
free for action. As the coin-receptacle i falls, the lever q is turned in an upward
direction through striking against the pins no p. This upward movement is free,
and has no effect. When the weight is removed from the platform, the coin receptacle
is raised by the pin w on the rod a, and the lever q, catching against the pins n, o, p,
is turned downwards and presses upon the end of the lever u, thus turning the
spindle t and arm y, so that the coin falls through. The weight e brings the rod a
into position again, and the pawl / falls back and re-engages in the notch j.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I wish it to be understood
that I am aware of the specifications of Percival Everitt No. 16433, A.D. 1884, George
Salter No. 6983 A.D. 1886, Henry Knight, No. 15580 A.D. 1886, and Percival Everitt
No. 10231, A.D. 1887, and I make no claim to anything contained therein, but I
declare that what I claim is :-
The combination, with lever weighing machines, of the above described mechanism,
for the purpose of freeing the apparatus by means of a coin.
