PROVISIONAL SPECIFICATION.
Improvements in Money Boxes.
EDGAR WORTHINGTON Mechanical Engineer 243 Upper Brook Street Man-
chester, do hereby declare the nature of this invention to be as follows:-
My invention relates to money boxes into which coins can at any time be placed,
but from which they can be taken only when the box iз full.
The box consists of a single cylinder made preferably of glass or other
transparent material, partly closed at one end by a fixed curved plate, which
completely closes a segment of the circular mouth of the cylinder, the larger portion
of the plate being curved away from the cylinder mouth to admit of a coin of
any particular size being inserted between the plate and cylinder end.
The cylinder may be preferably left open at the other end.
Within the box is a piston of wood or other material, sufficiently deep to slide
within the cylinder without locking itself. The piston is either perforated
transversely or grooved circumferentially for the reception of indiarubber or other
elastic packing, which rubs against the internal surface of the cylinder, and offers
resistance to any movement of the piston within it. This resistance increases with
the movement, until the latter amounts to about the thickness of the coin, after
which the packing and piston are forced along the cylinder. Thus the piston
presents elastic resistance to the insertion of a coin at the partially closed end of
the cylinder, and when a coin is pushed diagonally between the metal plate and the
cylinder-end to a position within the cylinder, it is held between the flat end of
the piston and the before-named segment of the metal plate and cannot be
withdrawn.
Other coins may then be inserted, one by one, beneath the metal plate, and they
will force the previously inserted coin with the elastic piston towards the open end
of the cylinder, on reaching which the whole contents of the box is released.

Improvements in Money Boxes.
I, EDGAR WORTHINGTON of 243 Upper Brook Street Chorlton-on-Medlock
Manchester, Engineer, 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 money boxes into which coins of any particular size can
be placed, but from which they can be taken only when the box is full.
The accompanying sheet of drawings illustrates the features of my invention :-
Fig. 1. is a longitudinal section through the middle of the box.
Fig. 2. is an end view of the top, looking from the outside of the box.
Fig. 3. is a side view showing the box made of one piece of transparent material
and partly filled with coins.
Fig. 4. shows an alternative arrangement of the movable internal piston.
In the following description the capital letters refer to the particular parts
indicated by the corresponding letters on the several figures.
A single cylindrical tube A made preferably of glass or other transparen
material, is partly closed at one end by a fixed cap B C D F made of glass, metal

page_text: or other suitable material, and either in one piece with, or securely fastened to, the
tube.
The flat inside surface C of the cap B C D F is at right angles to the
longitudinal axis of the tube A, and covers a segment of the circular end of
the tube.
The cap B C D F is shaped or bent sharply along the chord H H away from
the cylinder A; and that portion of the cap consisting of the tongue D and a
portion of the strengthening rib or corrugation F extends over the remaining
segment of the circular end of the tube A, at a distance from it sufficient to
admit of the insertion of a coin through the orifice E and beneath the flat portion C
of the cap.
The other end M of the tube A is left open, and within the tube is inserted a
piston K of wood or other suitable material, surrounded by an elastic ring L, or
pierced by elastic bars N N. The piston K forms a sliding bottom to the box, and
is made a little less in diameter than the bore of the cylinder. This piston is
sufficiently long to guide itself longitudinally within the cylinder A without locking
while it is forced along the cylinder A in either direction.
The packing ring L, or bars N N, are formed of india-rubber or other elastic
material, and are slightly larger in diameter than the internal diameter of the
tube A, so that the ring L or bars N N press against the cylinder A and cause
frictional resistance to the passage of the movable piston or bottom K within the
cylinder A.
The sides O & P of the piston K are convex in form, the side O being longer
and less convex than the side P, so that the packing ring L is forced more tightly
against the sides of the cylinder A when the piston K is travelling towards
the open end of the box than when the piston K is travelling in the opposite
direction within the box.
The box is used as follows :-
The piston or bottom K surrounded by the packing ring L, or pierced by the
packing bars N N, is inserted in the open end M of the tube A and is forced
along the tube until it touches the flat segment C of the cap B C D F. A coin
is then inserted through the opening E and is forced diagonally between the chord
line H and the piston K, depressing the latter and bending the packing L or N,
the outer surface of which adheres to the cylinder A. When the coin has
passed through the orifice E the pressure of the piston, caused by the elastic
resistance of the packing, forces the coin to assume a position at right angles to the
axis of the cylinder A, and clips the coin between the flat segment C and the
piston K.
Other coins may follow the first coin through the orifice E, and they will range
themselves in a pile G between the piston K and the flat segment C. The coins G
will be visible through the cylinder A, and they cannot be released until the
piston K reaches the open end M of the box A, when the piston may be removed
and the coins released.
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. A cylindrical tube of glass or other material, closed over a segment of one end
by the flat portion of a plate, the other portion of the tube-end being covered by
a corrugated tongue-shaped extension of the said plate, beneath which coins may
be forced diagonally into the tube between the aforesaid flat portion of the plate
and a sliding piston with rubber packing, substantially as described.
2. A cylindrical coin holder having a sliding piston which forms the movable
bottom of the holder, this piston being surrounded circumferentially or pierced
diametrically by a ring or bars respectively of india-rubber or other elastic packing,
in order to impede the motion of the piston along the cylinder.
3. In a cylindrical coin holder a sliding piston or coin receiver encircled by a

page_text: packing ring of rubber, or other elastic material, lying in a recess of the piston, one
side of the recess being so shaped as to press the rubber ring against the internal
surface of the cylinder while the piston is forced by the inserted coins towards the
open end of the holder, the other side of the recess in the piston being so shaped as
5 to drive the rubber ring along the cylinder while the piston is pressed by hand
towards the capped end of the holder, substantially as described.
