JAMES SIMEON EDGE, the younger, of Yardley, in the County of Worcester,
Mechanical Engineer, and JOHN DEELEY; of Birmingham, in the County of
Warwick, Gun Manufacturer. "IMPROVEMENTS IN THE MANUFACTURE OF
METALLIC DOOR AND OTHER KNOBS OR HANDLES, AND IN ATTACHING DOOR
AND OTHER KNOBS OR HANDLES TO AND ADJUSTING THEM ON THEIR SPINDLES."
In manufacturing metallic door and other knobs or handles according to one of
our improvements, we make both the body and the neck of the knob or handle by
stamping from sheet metal. In the back of the body, at the place where it is to be
joined to the neck, an internal collar or short tube is made. This internal collar
joins the body of the knob by a sunken shoulder, thereby leaving around the said
internal collar a depression or seat, into or against which a flange on the tubular
neck having the same curvature as the said body fits. The outer end of the
tubular neck is bell mouthed. The tubular neck is connected to the body by
soldering its flange to the internal shoulder in the body, or when the knob is to be
attached to its spindle, according to the method hereinafter described, the neck is
loose, the flange on the neck seating itself against the internal shoulder on the
body; or the neck part of the knob may be made in halves by stamping instead of
in one piece. In this modification we form two bell mouthed pieces, each piece
having in its interior a short tube. The half necks when brought together end to
end form a neck having in its interior a tube, which is screwed with a screw
thread proper to take upon the screwed end of the spindle. The inner half neck
is connected to the body of the knob by spinning or otherwise.
In attaching knobs or handles to and adjusting them on their spindles, according
to our Invention, we make the whole or part of the neck separate from the body
of the knob, as hereinbefore described, the separate neck and body or half necks
being screwed internally for screwing upon the screwed end of the spindle.
The separate neck or one of the half necks is by this construction independent
of the other part of the knob, the said separate neck or half neck constituting the
adjusting and locking or fixing portion of the knob, as herein after described.

page_text: In attaching the knob to and adjusting it on its spindle, the spindle with the
fixed knob on one end is passed through the door, and the screwed neck or half
neck is screwed on the protruding end of the spindle until the said neck abuts
against the door.
The body of the knob is next screwed on the spindle until its face, or the face of
its fixed half neck, takes a close bearing against the face of the separate neck or half
neck which has been adjusted on the spindle.
By now giving a back motion through a small angle to the screwed neck or half
neck, that is, a motion in a direction proper to screw it off the spindle, the said neck
or half neck is advanced against the stationary portion of the knob. By this back
motion of the said neck or half neck, it is made to bind itself so firmly against the
body of the knob as to lock itself upon the spindle, and also to lock the body part
on the spindle. The two parts of the knob are thus connected together and to the
spindle. To disconnect the knob the screwed neck or half neck is moved in a
direction proper to screw it on the spindle, it is thereby made to retire slightly
from the other part of the knob, causing the unlocking of the two parts of the
knob, and permitting of their removal from the spindle.
The locking and unlocking of the separate screwed neck or half neck may be
effected either by a spanner applied to the angular end of the neck or half neck, or
by a rod, bradawl, or other like tool, passed into a hole in the said neck or half
neck.
The locking action hereinbefore described for fixing the knob on the spindle,
although most conveniently applied in the neck of the knob, may, however, be
applied to the knob itself, one part of the knob containing one part of the screwed
tube in which the spindle takes, and the other part of the knob containing the
other part of the said screwed tube.
Our improvements in attaching knobs to spindles may be applied to non-metallic
knobs; in these cases we employ a metallic neck or mount..
