PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Knobs or Terminal
Ornaments.
I WILLIAM WADDELL of Wishaw Lanarkshire Sheet Metal Worker I do
hereby declare the nature of this invention to be as follows:-
And consists in placing within the centre or spherical part of those knobs or
terminal ornaments made from sheet metals and used for cans pole ends &c. a
disc stay or support of desired shape by which means the halves or parts are more
quickly easily and firmly fixed and held together and the said knobs or terminal
ornaments are also strengthened.
Dated this Fifth day of September 1895.

Improvements in the Manufacture of Knobs or Terminal
Ornaments.
1 WILLIAM WADDELL of Russell Street Wishaw Lanarkshire Scotland,
Sheet Metal Worker, 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 has reference to those knobs or terminal ornaments drawn,
stamped, or spun from sheet metal in halves or parts and joined together there-
after by lapping or spinning the one edge over on the other.
This invention has for its object the more quickly and securely joining of the
parts together and otherwise staying or strengthening the knob or terminal
ornament, and consists in placing within the central or spherical part one or more,
discs, stays, or supports of any desired shape according to the different design of
knob or terminal ornament.
For the purpose of my invention I form within the inner half or part at or near
edge to be joined a groove or recess.
I also in the face of base or stem of same form a recess, (preferably hex shaped)
the disc stay or support is formed as a circular blank the edges of which fit into
the recess or groove formed in the inner half or part at edges to be joined and has
a vertical part carried down into base or stem.
On the outer half or part of knob or terminal ornament 1 form a groove or
recess corresponding to that on the inner part, I then place the disc stay or
support into place in the inner part and the inner part into the groove formed in
the outer part and with suitable dies press the edge of outer part over on to the
edge of inner part and the edge of inner part over on to the disc, stay or support,
the disc stay or support thus keeps the inner part from fleeing from the outer
part while being pressed over on to the inner part and thus enables the joining to
be more quickly and securely made than heretofore while the vertical part which
is carried down into base or stem strengthens the same and may be screwed to
form a better and stronger means of attaching to any other object.

page_text: The disc, stay or support may either be made in one piece and put entirely
within the inner part or it may be made in two parts and joined together at H as
shewn on the accompanying drawings.
In order to illustrate more clearly my invention I send herewith a drawing of a
knob or terminal ornament spherical shaped and suitable for a bedstead or such
like with my invention carried out in which the disc, stay or support is made in
two parts, the disc or circular part is put into place in groove of inner part at the
edge to be joined, and the vertical part is put in from face of based stem part and
joined together at H by being screwed or rivetted.
Fig. 1 is a plan and Fig. 2 is a section of elevation cut through the line A. B.
C. D, represents the disc, stay or support. C. the disc part and D, the vertical
part which are joined together at H.
Lis the base or stem and G. the hex shaped part.
C is the inner part and F the outer part which are joined together as at I
and K.
Having now particularly described and ascertained the nature of my said inven-
tion and the manner in which the same is to be performed, I declare that what
I claim is
That in the manufacture of those knobs or terminal ornaments made from sheet
metal and thereafter joined together at the edges, the placing within the central
or spherical part, one or more discs stays, or supports, by which means the parts
may be more quickly and securely joined together and the knob or terminal
ornament stayed and strengthened all as herein disclosed.
Dated this 10th day of July 1896.
WM. WADDELL.
