"IMPROVEMENTS IN THE MANUFACTURE OF METALLIC KNOBS OR TERMINAL
ORNAMENTS FOR THE PILLARS OF METALLIC BEDSTEADS, COTS, AND COUCHES,
AND OTHER METALLIC PILLARS, AND FOR OTHER PURPOSES."
Our Invention consists of the improvements herein after described, in the
manufacture of metallic knobs or terminal ornaments for the pillars of metallic
bedsteads, cots, and couches, and other metallic pillars, and for other purposes, such
for example, as door knobs and balance weights for chandeliers.
Our Invention is applicable to the manufacture of such metallic knobs or terminal
ornaments as have bodies made in halves, the said halves being joined together by
their edges overlapping, and being secured by soldering or otherwise, as well as to
knobs in which the halves are connected by the process called "mounting."
The bodies of knobs or terminal ornaments of this kind may have a spherical or
bulbous figure or other ornamental figure, but we will describe our Invention as
applied to a knob or terminal ornament having a spherical body. According to
our Invention we make the screwed neck by which the knob or terminal ornament
is attached to the pillar separate from the lower hemi-spherical half body, and we
attach the said screwed neck to the said lower half body in the following manner: -
We make the screwed neck by casting and the half body by stamping in dies. We
make at the top of the said cast neck four (or other number of) equi-distant ears,
and we pierce out a circular hole in the base of the hemi-spherical half body, and
make around the said hole four (or other number of) equidistant slots of a size
and shape proper for receiving the equi-distant ears on the cast neck. By passing
the ears on the neck through the slots in the half body, and bending the said ears
outwards so as to close them upon the inside of the said half body, the cast screwed
neck is firmly connected to the half body. The closing or bending of the ears upon
the inside of the half body may be effected by dies or otherwise.
In order to insure the more effectual fixing of the closed ears in their places
inside the half body, the said ears may be soldered to the body. After the screwed
neck has been thus connected to the lower half body, the upper half body is secured

page_text: to the said lower half body in the ordinary way, and the knob or terminal
ornament is complete.
When the summit of the knob or terminal ornament is required to be furnished
with a termination having the same general figure as the screwed neck at the base
of the knob or ornament, we form the said termination by casting or otherwise, and
connect to the upper half body in the manner described with respect to the screwed
neck, that is, the base of the terminal part of the upper half of the knob is furnished
with ears, and the summit of the upper half body is pierced out and furnished
with slots to receive the ears on the terminal part, which ears are closed upon the
inside of the said half body so as to fix the terminal part to it. The two half
bodies with their respective neck and terminal parts are afterwards connected
together in the ordinary way.
By manufacturing metallic knobs or terminal ornaments for the pillars of metallic
bedstead and other pillars and for other purpose according to our Invention, the
screwed necks or screwed necks and terminations of the said knobs or ornaments
are very strong, and are securely connected to the base or base and summit of the
knob or ornament.
