An Improvement or Improvements in or in connection with
Rosettes or Caps for Billiard Tables.
I, JOHN ROBERTS of 99 Regent Street, in the County of London, Billiard
Table Manufacturer and Ivory Turner, 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 refers to simple, efficient, and comparatively inexpensive means for
covering the bolt heads used in the manufacture of billiard tables, for bracing and
holding the parts together.
Many arrangements have for years been adopted for the above purpose. One
of the old arrangements, and very generally used, was to counter-sink the screw
head in the wood of the framing, sufficiently deep to allow room above the screw
head to insert a plug on a rosette; this was, to some extent, objectionable, because
of the necessity of counter sinking the head to a considerable depth, and the
necessity of boring two holes of different diameters, thus causing considerable work
and consequent expense.
It has been proposed to screw thread the periphery of the heads of circular
headed bolts and to screw the cap or rosette on to such threaded head.
It has also been proposed to secure such caps or rosettes to the screw heads by
means of a screw passing through the rosette and tapped into a hole drilled in the
bolt-head.
According to my invention 1 dispense with any threading or tapping of the bolt
or screw head by forming the cap, cover, or rosette with a recess ou its inner face,
sufficiently deep to take the head of the screw, and to receive a lining of some
elastic material, such as cork, india rubber, dermatine, gutta percha, or the like,
and when thus constructed, the rosette or cap is placed over the projecting head
of the screw, the head fitting tightly within the lining of the recess, and allowing
the inner face of the cap to come up to, and in close contact with, the face of
the woodwork, so that not only is the cap or rosette held by the elastic lining
of the recess, but the polish or varnish upon the wood surface also adds to the
security of the attachment.
Fig. 1 of the accompanying drawings shows in sectional elevation, a bolt having
a rosette applied in accordance with my invention, and Fig. 2 is a transverse
section of same showing the inner face of the rosette.
A is the shank of the bolt, B is the head, and C is the lining of the recess
in the rosette D.
The heads of the bolts may be of any desired shape, not necessarily circular,
but may be square, hexagonal, or the like.
The rosette may be formed with any desired pattern as fancy or taste may
dictate.
By my invention the rosette is applied, simply by being pushed on to the
projecting head of the bolt, whereby drilling holes, tapping or screwing the head or
other part of the bolt in order to secure the rosette is wholly dispensed with.
Having now particularly described and ascertained the nature of my зaid inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The caps, covers, or rosettes for covering the heads of bolts in billiard tables,

page_text: composed of a body part, a recess formed therein and a lining of elastic material in
the recess to suit the form and size of bolt head required, the said caps, covers, or
rosettes, being applied by being pressed on to such bolt heads, all substantially as
and for the purposes described and illustrated with reference to the accompanying
drawings.
