I, GEORGE ANDREW MACBETH, of 8 College Land, St. Mary's Street, Manchester
Manufacturer do hereby declare the nature of this invention to be as follows:-
My Invention relates to improvements in the automatic delivery apparatus for which
Letters Patent were granted to me, dated the 22nd day of September 1886 and
numbered 12,079.
My first improvement has for its object to ensure that the hopper of the rotating
magazine from which the goods are for the time being, to be delivered, shall bo
exactly in the proper position with regard to the lug or finger of the delivery
slide, notwithstanding that the rotating magazine may have been carelessly or
inaccurately adjusted.
To this end, the improvement consists in providing the magazine with means
whereby it will be automatically brought to its proper relative position, after being
partially rotated in order to bring another hopper into position for delivery. These
means consists of an undulating cam plate whose undulations correspond in position
to the hoppers of the magazine, and of rollers pressed against the cam plate and
falling into the undulations thereof so as to ensure the turning of the magazine to
the proper extent. The preferred arrangement is to cause the weight of the drum
itself to apply the pressure necessary to carry it round to the desired point. For this
purpose, the drum is mounted loose upon its axis so that it is free to rise and fall
whilst turning therewith and the cam plate attached to the bottom of the drum rests
upon a pair of rollers mounted on fixed axes so that the drum will be caused to
rise and fall by the cam plate in passing over the rollers.
My Invention has secondly for its object to provide more effectually against theft
of the goods. For this purpose, I attach to the rear end of the inner tube, an arm
carrying a latch-lever which upon the inward motion of the tube, passes up the
surface of a pivoted switch and falls into the path of a rack whereby the further
operation of the delivery apparatus is prevented until the inner tube has been allowed
to resume its normal position for receiving another coin.

page_text: My Invention has thirdly for its object to prevent the retention of the coin in position
to enable the unlocking mechanism to be worked a second.time by the same coin;
and for this purpose, I pivot a lever, in such position as to be acted on by the motion
of the delivery slide and to be thereby caused. to act on the coin held between the
pusher and the inner spring pressed tube in such a way as to forcibly eject the coin
from its position after it has effected its purpose of unlocking the delivery mechanism.
By these means, the fall of the coin is ensured by a positive action, notwithstanding
that it may be attempted to retain the coin in, operative position by means of some
adhesive material.

Improvements in Apparatus for Automatically Delivering Goods in
Exchange for Coin.
I, GEORGE ANDREW MACBETH of 8, College Land, St. Mary's Street, Manchester,
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 :-
My Invention relates to improvements in the automatic delivery apparatus
for which Letters Patent were granted to me, dated the 22nd day of September 1886
and numbered 12079.
Such automatic delivery apparatus comprises a magazine or drum having a number
of vertical hoppers, containing different descriptions of goods, the magazine being
rotatable by the purchaser for the purpose of bringing any particular hopper into
position for delivering the kind of goods selected. It also comprises delivery and
locking mechanism adapted to be freed by pressure acting through the medium of a
coin of the proper value inserted between a push handle and the locking mechanism-
of the delivery drawer.
My first improvement has for its object to ensure that the particular hopper of the
rotating magazine, from which it is desired by the purchaser that the goods shall be
delivered shall be brought to exactly the proper position with regard to the lug or
finger of the delivery slide, notwithstanding that the rotating magazine may have
been inaccurately adjusted by the purchaser.
My Invention has secondly for its object to provide more effectually against the
possibility of theft of the goods being effected by the retention by any external means
of that part of the delivery apparatus on which the push rod acts through the medium
of the coin, in such a position that the delivery drawer can be made to effect a
second delivery without the introduction of a fresh coin.
My Invention has thirdly for its object to prevent the retention of the coin in
position to enable the unlocking mechanism to be worked a second time by the same
coin.
Reference is to be had to the accompanying drawings forming part of this
specification, wherein figure 1 is a vertical section of the automatic delivery apparatus
shewing as much of the mechanism as is necessary to illustrate my first and second
improvements. Figure 2 is a plan, and Figures 3 and 4 are sections on lines 1-1
and 2-2 figure 2 respectively. The same letters of reference indicate like parts in
all the figures.
A A are two of the hoppers of the magazine B is the delivery slide or drawer,
and b is the lug or finger by which the delivery is effected from the hopper which is
for the time being in position above the slide. The delivery slide is actuated, locked,
and released, as described in my former patent to which reference should be had for
the description of parts not here referred to. The magazine drum is carried upon a
vertical axis C and is turned to bring the different hoppers into operative position by
means of an index handle D moving over a dial and geared with spindle C through
bevel gear.
The first improvement consists in providing the magazine with means whereby it

page_text: will tend to assume its proper relative position with regard to the delivery slide so
that when the magazine has been partially rotated, a hopper will come accurately in
position for delivery when the magazine stops.
These means consist of an
undulating cam plate E whose undulations correspond with regard to the hoppers of
the magazine and of rollers F which fall into the undulations of the cam plate so as
to ensure the turning of the magazine to the proper extent, the preferred arrange-
ment being that shown in which the weight of the drum itself is caused to apply the
pressure necessary to carry it round to the desired point. For this purpose, the
drum is mounted loose upon its axis C which is square so that the drum is caused
to turn therewith but is free to rise and fall thereon, and the cam plate is attached to
the lower part of the drum and rests upon the pair of rollers F mounted in fixed
standards so that the drum will be caused to rise and fall by the undulations of the
cam-plate passing over the rollers.
It will however, be obvious that instead of the weight of the drum being the motive
power by which it is brought into exact register with the delivery drawer the
undulating cam might be pressed upon by one or more rollers each carried by a spring
in which case the drum need not slide upon its axis C.
The second improvement relates to the delivery drawer locking and releasing
mechanism. B is the spring actuated delivery drawer locked as described in my
former patent through the medium of a tubular slide H carrying a lug which engages
with a locking lever I engaging in a notched slide on the delivery drawer the longi-
tudinally sliding tubular slide H being moved to relieve the delivery drawer by
pushing in a push knob K when a coin of proper size is introduced between them.
This tubular slide carries the cover plate L by which the money slot is closed so long
as the, delivery slide remains projected forward after delivery, and the present
improvement has for its object to guard against the slide H being held, by an instru-
ment acting on the plate L, in such a position that the delivery drawer will not be
relocked when pushed in again. For this purpose, I attach to the rear. end of the
delivery drawer locking slide H an arm M terminating in a pivoted latch m which
upon the inward motion of the slide H passes up the surface of a switch N and falls
into the path of a rack tooth n fixed on the delivery drawer upon which the switch N
is also pivoted. When the delivery drawer is pushed partly in, the latch m engages
with the tooth n and so prevents the delivery drawer coming forward again until the
locking slide H has been allowed to resume its normal position wherein its lug
engages lover I and so locks the delivery drawer.
at
The third improvement is illustrated in figures 1, 2, and 3, and consists of a finger
lever P pivoted in such position as to be acted on by the motion of the delivery
drawer and to be thereby caused to forcibly eject the coin from the position in which
it is held between the pusher K and the spring pressed locking slide H, after the coin
has served the purpose of a medium through which the unlocking of the delivery
mechanism is effected. By this means the retention of the coin in operative position
by the aid of an adhesive substance is rendered impossible. This lever P is pivoted
Ρ to a fixed support and its tail end is received in a slotted plate R affixed to the
delivery drawer, the slot having a sudden deviation » from the straight form whereby
the lever is suddenly oscillated. The other end of the lever projects through an
opening in the top of the guide tube in which the locking slide H works, and it is
directly over the coin when the latter has been pushed back by the pusher K so that
on the delivery drawer being released and moved suddenly forward by its actuating
spring the lever is caused by the part of the slotted bracket R to strike the coin a
smart blow and knock it down into the coin receptacle beneath.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. The combination with the magazine drum of an undulating cam plate and of a
roller running thereon and means whereby pressure is applied thereto for the purpose
wified

page_text: 2. The herein described means of ensuring accurate adjustment of the magazine
drum which consists in the combination with the drum mounted to turn with but
slide on, its axis, of the undulating cam plate and of rollers bearing against the
undulating face of the cam whereby the weight of the drum is made the medium
whereby it is brought into accurate register with the delivery drawer, as specified.
3. The combination with the delivery drawer and its locking and releasing slide H.
of the detent and switch mechanism substantially as specified whereby a second
forward motion of the delivery 'drawer will be rendered impossible even though the
locking slide H be prevented from re-locking the delivery drawer through the lever I
as described.
4. The combination with the delivery drawer, of the herein described coin ejecting
lever operated substantially as specified.
