PROVISIONAL SPECIFICATION.
An Appliance for Securing Buttons, Bosses, or Caps Covering Bolt
or Screw Heads.
I, FREDERICK ROBERT WRIGHT, of No 162 Westminster Bridge Road, in
the County of Surrey, Billiard Table Manufacturer, do hereby declare the nature
of this invention to be as follows:-
My invention relates to an improved appliance for securing buttons or caps
covering bolt or screw heads such as are required more particularly in articles of
furniture, such as billiard tables and the like.
According to my invention I construct the tubular socket or lining piece that is
fitted into the hole in the woodwork through which the bolt or screw is passed,
with an enlarged outer end of such a size as to receive within it the head of the
bolt or screw,
and round the cylindrical outer surface of such enlargement I fit a
caoutchouc ring, preferably held thereon by fitting partially into a shallow groove
in the head. I make the button or cap with a hollow of such a diameter as to fit
tightly over the outer circumference of the caoutchouc ring, so that when the
is fitted on, the ring is slightly compressed thereby and thus holds the cap on with
spring action so that it can only be removed on exerting a certain amount of
force.

COMPLETE SPECIFICATION.
An Appliance for Securing Buttons, Bosses, or Caps Covering Bolt
or Screw Heads.
I, FREDERICK ROBERT WRIGHT, of No 162 Westminster Bridge Road, in
the County of Surrey, Billiard Table 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 an improved appliance for securing buttons or caps
covering bolt or screw heads such as are required more particularly in articles of
furniture, such as billiard tables and the like.
According to my invention as shewn in section in Fig. 1 and elevation in Fig. 2
I construct the tubular socket or lining piece A. that is fitted into the hole in the
wood work through which the bolt or screw B is passed, with an enlarged outer end
and round the cylindrical outer surface of such enlargement 1 fit a caoutchouc
ring C, which is larger than the head of the bolt or screw B and is held on the
socket head by fitting partially into a shallow groove in the head. I make the
button or cap D with a hollow of such a diameter as to fit tightly over the outer
circumference of the caoutchouc ring C, so that when the cap D is pushed on, the
ring is somewhat compressed thereby and thus holds the cap on with frictional
pressure so that it can only be removed on exerting a certain amount of force.

page_text: In cases where the button, instead of having a hollow enclosing the bolt head
has a boss projecting into a hole of the table or other piece of furniture, I employ
the modification shewn in Fig. 3, providing in the boss E of the button D a groove
to receive the caoutchouc ring C, which in this case, when the boss is pushed into
the hole, is somewhat compressed thus holding the boss with frictional pressure.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
'
An appliance wherein a caoutchouc ring is employed for securing a button cap
or the like for covering heads of bolts or screws, substantially as described with
reference to the drawings.
