PROVISIONAL SPECIFICATION.
Improvements in Knobs for Insertion in or Attaching to Cardboard,
such as are Used for Revolving Calendars, and for like
purposes.
I, BENJAMIN EDMUND EDWARDS of 14 Grove Terrace, Highgate Road
London, Photographic Chemist, do hereby declare the nature of this invention to
be as follows:-
This invention consists of a small hollow knob, raised from a piece of thin metal
in any suitable manner, the upper part of which is by preference roughened or
corrugated to resemble milling, so that it shall not slip when held between the
finger and thumb. On the open end which has a diameter of about three-eighths
or half of an inch, two or more spikes or talons are formed so that the knob can
be attached to cardboard thin wood and the like, by passing the spikes through and
turning them down on the reverse side. For purposes where the strain is great, a
separate plate may be added of a length of one to two inches or thereabouts, the
ends of which are turned down and passed through the card similarly. Holes are
made in this plate to receive the spikes of the kuob.
The effect of this plate is to render the knob more secure, by preventing the
spikes from wearing or cutting away the card and so working loose.
Dated this 18th day of September 1895.

Improvements in Knobs for Insertion in or Attaching to Cardboard,
such as are Used for Revolving Calendars, and for like
purposes.
I, BENJAMIN EDMUND EDWARDS of 14, Grove Terrace, Highgate Road,
London, Photographic Chemist, 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 is designed to provide an inexpensive and efficient substitute for
the solid knobs which are now used for attachment to calendars, almanacs and like
purposes.
It consists of a small hollow knob, raised from a piece of thin metal in any
suitable manner, the upper part of which is by preference roughened or corrugated
to resemble milling, so that it shall not slip when held between the finger and thumb.
On the open end which has a diameter of about three-eights or half of an inch,
two or more spikes or talons are formed so that the knob can be attached to card-
board, thin wood and the like, by passing the spikes through and turning them
down on the reverse side. For purposes where the strain is great, a separate plate
may be added of a length of one to two inches or thereabouts, the ends of which
[Price 8d.1

page_text: are turned down and passed through the card similarly. Holes are made in this
plate to receive the spikes of the knob, which are turned down beneath the plate
in the usual way.
When attaching the knobs to paper discs or other thin material, the effect of
this plate is to render the knob more secure, by preventing the spikes from wearing
or cutting away a portion of the said paper or other thin material and so working
loose.
I will now describe the invention with reference to the accompanying drawing in
which :-
Fig. 1 is a plan and elevation of my improved knob, the chief feature of which
is its being hollow and raised or stamped up from a piece of flat metal.
Fig. 2 is an elevation of the knob in position ready for fixing, the points a being
inserted in the card board or other material d.
Fig. 3 is a sectional elevation of the knob fixed in position, the points or talons a,
being folded or bent as shown, or if preferred, they could be bent outwards as
indicated by the dotted lines a¹.
Figs. 4 and 5 show my improved knob in combination with a metal plate c, also
provided with points a². This plate gives a better hold on thin and weak materials.
It may have spikes on the side at a³, and may be of any preferred shape or outline
as for instance round or annular.
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 raised hollow metal knob of suitable size and shape, preferentially made
with smooth neck and domed head or summit, with roughened or milled edge to
same, and furnished with spikes for insertion into paper, cards or other material,
as a knob for calendars, and for like purposes, as herein described and set forth.
2. The combination of the above knob with a supplementary plate of any
suitable shape, said plate having slits to receive the spikes of the knobs and having
spikes for attaching to paper, card and other suitable material, as herein described
and set forth.
