PROVISIONAL SPECIFICATION.
An Appliance for Securing Buttons or Bosses 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
-
In many cases, especially in articles of furniture, such as billiard tables and the
like, the heads of bolts or screws for holding parts together are sunk into the wood
some depth below the surface, and buttons or bosses of more or less ornamental
design are inserted in the holes to cover the heads Such buttons or bosses must
be capable of being removed so as to give access to the heads of the bolts or screws,
and, as they are fitted more or less loosely in the holes, they are apt to be shaken
out and to become mislaid or lost.
My invention relates to means of securing such buttons or bosses, which I effect
in the following manner. I make the button or boss of larger diameter than the
head of the bolt or screw and form a circular recess in the interior of the boss or
button so that when put in its place, it not only covers the head but also encloses it
within its recess.
Under the head of the bolt or screw I place a washer from which two or more
limbs stand up at right angles to the plane of the washer outside the periphery of
the head and beyond it. These limbs being elastic and slightly bent outwards about
their middles, are compressed within the recess of the button or boss when it is
forced into its place, and they thus give such frictional hold of the button or boss
that it requires considerable force to remove it, and thus it is not liable to be shaken
out.

An Appliance for Securing Buttons or Bosses 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 :—
In many cases, especially in articles of furniture such as billiard tables and the
like the heads of bolts or screws for holding parts together are sunk into the wood
some depth below the surface and buttons or bosses of more or less ornamental
design are inserted in the holes to cover the heads. Such buttons or bosses must be
capable of being removed so as to give access to the heads of the bolts or screws,
and, as they are fitted more or less loosely in the holes, they are apt to be shaken out
and to become mislaid or lost. My invention relates to means of securing such
buttons or bosses which I effect in the manner shewn in the accompanying drawings.
Fig. 1 is a section shewing a bolt and its covering boss. Fig. 2 is a perspective of
the washer.
I make the button or boss A of larger diameter than the head B of the bolt or
screw, and form a circular recess in the interior of the boss or button, so that when
put in its place, it not only covers the head but also encloses it within its recess.

more limbs D stand up at right angles to the plane of the washer outside the periphery
of the head and beyond it These limbs being elastic and slightly bent outwards
about their middles, are compressed within the recess of the button or boss A when
it is forced into its place, and they thus give such frictional hold of the button or
boss that it requires considerable force to remove it, and thus it is not liable to be
shaken out.
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.
In combination with the button or boss covering a bolt or screw head, a washer
with elastic limbs engaging within a recess of the button or boss, substantially as
described.
