Improvements in Parts of Coin-freed Mechanism,
We, JOHN HENRY BIRCH, of the Firm of George Salter & Company, Manufac-
turer, and JOHN HUGHES, Foreman of Works, both of West Bromwich, in the
County of Stafford, do hereby declare the nature of this invention to be as
follows:-
This invention relates to those parts of coin-freed automatic mechanism which
are located within or in proximity to the coin slot, coin shoot or race of same.
In ordinary coin freed mechanism, the introduced coins are apt to become lodged
between the levers or like moving parts and the casing or sides of the shoot owing
to such levers or the like generally having a certain amount of freedom of move-
ment upon their bearings or joints, and such lodgement frequently causes the
derangement of the mechanism of the machine, which is thereby rendered
inoperative.
The object of this invention is to render such jambing of the levers impossible,
and this we propose to effect by providing the opposite sides of the levers, arms,
links or like movable parts with extensions or studs, taking into corresponding
slots, channels or depressions formed in the opposed faces or sides of the shoot,
casing, or equivalent parts, so that these studs cross or break joint with the spaces
between the opposed surfaces of the levers or like moving elements and the parts
between which they work.
In one form of our invention, the casing is made up of two opposed plates or
flat castings with the sunken inner surfaces presented to each other, and having
formed within it, a coin race or shoot with levers, arms or movable elements
for controlling the mechanism, hung or mounted in the said shoot and within
the path of the coin.
These levers or arms have a series of studs or projections disposed along the
two opposite sides and near to one edge thereof, preferably that edge against which
the coin falls or comes and these studs take into and traverse within slots or
depressions formed in the sides of the casing and being of the same extent as
the throw made by the said projections or studs when moving with the lever,
and which studs form stops for preventing the coin from getting between the
faces of the lever and casing and thereby obviate wedging or jambing of the
mechanism.

page_text: Improvements in Parts of Coin-freed Mechanism.
We, JOHN HENRY BIRCII, of the Firm of George Salter & Company, Manufac-
turer, and JOHN HUGHES, Foreman of Works, both of West Bromwich, in the
County of Stafford, 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 those parts of coin-freed automatic mechanism which
are located within or in proximity to the coin slot, coin shoot or race of same.
In ordinary coin freed mechanism, the introduced coins are apt to become lodged
between the levers or like moving parts and the casing or sides of the shoot owing
to such levers or the like generally having a certain amount of freedom of move-
ment upon their bearings or joints, and such lodgement frequently causes the
derangement of the mechanism of the machine, which is thereby rendered
inoperative.
The object of this invention is to render such jambing of the levers impossible,
and this we propose to effect by providing the opposite sides of the levers, arms,
links or like movable parts with extensions or studs, taking into corresponding
slots, channels or depressions formed in the opposed faces or sides of the shoot,
casing, or equivalent parts, so that these studs cross or break joint with the spaces
between the opposed surfaces of the levers or like moving elements and the parts
between which they work.
Figure 1 of the accompanying drawing represents a front elevation of a coin-
freed automatic rack or holder adapted to temporarily support a bicycle, the coin
shoot mechanism of which is provided with means for preventing the jambing
of the moving parts constructed and arranged in accordance with our invention.
Figure 2 represents a view of the apparatus with the front cover removed show-
ing the coin shoot and the rocking levers arranged in connection therewith, which
have studs or extensions on their opposed sides taking through clearances in the
cpposed plates between which they work.
Figure 3 is an elevation at the inner side of the cover plate, showing the recesses
or sinkings provided therein for receiving the studs or projections on the opposed
faces of the levers or arms.
Figure 4 is a section of one of the said rocking levers and the cover plate and
inner plate between which it is pivoted, taken upon the dotted line a, Figure 2.
Figure 5 is a similar section as Figure 4, but with the said plates separated
away from the lever.
Figure 6 represents an elevation and an edge view of one of the rocking levers,
and
Figure 7 shows like views of the other lever.
Figure 8 is a section of Figure 2 upon the dotted line ¹, showing how the
coin impinges against the edge of the said lever but is prevented from getting
underneath it by the studs extending into the gaps or clearances in the plates
whereon said lever is mounted.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
The particular form of coin freed apparatus to which our improvements are
shown applied in the said drawings is a cycle holder or rack of that type in which
a coin a, introduced through a coin slot b, and passing down a coin shoot b¹, is
arrested by, and is made to form a connection between, a pair of levers c, d, so that
on the lid e, of the apparatus being slightly raised, the lever c, is (by means of
internal mechanism not shown) rocked upon its joint c¹, and its motion is com-

page_text: municated through the coin a, to the other lever d, which is also turned upon its
joint, and a blocking stud or peg 20, extending into the interior of the apparatus
is thereby taken out of engagement with a slide part which is thus left free to be
traversed on the further raising of the lid and the grips are opened to receive
the wheel of a bicycle.
The coin shoot 6, and the levers c, d, are arranged between a pair of opposed
plates or flat castings g, h, with the surface of the outer or cover plate g, opposed
to the sunken surface of the inner plate h, whilst the said levers or arms c, d,
have a series of studs or projections, ², disposed along the two opposite sides
and near to one edge thereof, preferably that edge of each lever against which
the coin falls or comes and these studs respectively take into and traverse within
corresponding depressions or clearances g', g³, on the inner side of the outer cover
plate g, and holes or path-slots h¹, h², through the walls of the inner plate, and
which said depressions and holes are all of the same extent as the throw made
by the said projections or studs when moving with the levers, and form stops
for preventing the coin from getting underneath either of the levers or between
them and the cover plates and thereby obviate wedging or jambing of the
mechanism.
It is to be understood that we do not confine our invention to the particular
type of apparatus represented in the drawings, as the same may be equally well
applied to all forms of coin-freed apparatus in which levers, arms or like parts of
the mechanism are arranged in the coin shoot or in any way within the path
of the coin.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
In coin-freed mechanism, providing the levers, arms, or other moving parts
against which a coin may come, at or adjacent to the edges, with studs, extensions
or equivalent projections, which are located and work within path-slots, channels,
depressions or equivalent clearances made in the opposed faces of the elements
between which the said moving parts are mounted, whereby the jambing of the
mechanism by the coin is obviated, substantially as herein described and set forth.
Dated this 13th day of September 1898.
