IMPROVEMENTS IN SECURING DOOR AND OTHER KNOBS AND HANDLES
Year: 1885

page_text: I, EDWARD VERNON BAILEY of Great Hampton Row Birmingham, in the
County of Warwick, Brass Founder do hereby declare the nature of said invention
for "IMPROVEMENTS IN SECURING DOOR AND OTHER KNOBS AND HANDLES," to be
as follows:-
My invention has reference to knobs and other handles, which are affixed or
secured to their spindles, by small screws or pins passing through the neck of the
knob, and taking either into countersunk holes in a plain spindle, or into a
longitudinal slot in a screwed spindle; the heads or outer ends of the screws or
pins being left uncovered, thereby allowing the screw or pin to rise or become
loose by constant vibration. The object of my said invention is to prevent the
screws or pins described, from becoming loose or rising from their seats or fixed
positions, by the jarring of a door or other object to which they may be attached
or connected. This I effect by a screw collar or ring which covers the head or
outward end of the screw, or other pin; thereby preventing the rising of the said
screw or pin, and so effectually securing the knob to its spindle.
I will first describe my improvements as applied to a screwed spindle which is
as follows. The front of the neck of the knob is larger in diameter than the other
part, and constitutes a boss or collar which is screwed or wormed; and through
this wormed boss or collar, the small screw or pin for affixing the knob to its
spindle passes. The head or end of the screw or pin lying a little below the
surface, so as not to interfere with the thread of the worm, and upon this screwed
boss, a screw ring or collar takes, which covers the head or outer end of the screw
or pin and so prevents it from rising or becoming loose; thereby effectually
securing the knob to its spindle.
In affixing a knob to its spindle after having been adjusted, the small screw or
pin is passed through the neck of the knob, with its inner end taking into the
longitudinal slot in the spindle, the head or outer end of the screw or pin lying
a little below the surface. The internally screwed covering ring is then screwed
upon the screwed part of the neck when the screw or pin is covered or enclosed.
The application of my invention to other forms of knobs, spindles and handles.
differs in no essential respect to the form described.
The covering ring described is provided with a flange upon its inner side, which
prevents it from screwing too far, over the neck of the knob.

page_text: I, EDWARD VERNON BAILEY of Great Hampton Row Birmingham in the
County of Warwick, Brass Founder, do hereby declare the nature of said invention
for "IMPROVEMENTS IN SECURING DOOR AND OTHER KNOBS AND HANDLES," and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
.
My invention has reference to knobs and other handles, which are affixed or
secured to their spindles, by small screws or pins passing through the neck of the
knob, and taking either into countersunk holes in a plain spindle, or into a
longitudinal slot in a screwed spindle; the heads or outer ends of the screws or
pins being left uncovered, thereby allowing the screw or pin to rise or become
loose by constant vibration. The object of iny said invention is to prevent the
screws or pins described, from becoming loose or rising from their seats or fixed
positions, by the jarring of a door or other object to which they may be attached
or connected. This I effect by a screw collar or ring which covers the head or
outward end of the screw or other pin; thereby preventing the rising of the said
screw or pin, and so effectually securing the knob to its spindle.
I will first describe my improvements as applied to a screwed spindle which is
as follows. The front of the neck of the knob is larger in diameter than the other
part, and constitutes a boss or collar which is slightly taper screwed or wormed;
and through this wormed boss or collar, the small screw or pin for affixing the
knob to its spindle passes. The head or end of the screw or pin lying a little
below the surface, so as not to interfere with the thread of the worm; and upon
this screwed boss, a screw ring or collar takes, which covers the head or outer end
of the screw or pin and so prevents it from rising or becoming loose; thereby
effectually securing the knob to its spindle.
In affixing a knob to its spindle after having been adjusted, the small screw or
pin is passed through the neck of the knob, with its end taking into the longi-
tudinal slot in the spindle, the head or outer end of the screw or pin lying a little
below the surface. The internally screwed covering ring is then screwed upon the
screwed part of the neck when the screw or pin is covered or enclosed.
The application of my invention to other forms of knobs, spindles and handles,
differs in no essential respect to the form described.
The covering ring described is provided with a flange upon its inner side, which
prevents it from screwing too far, over the neck of the knob.
I will now proceed to describe with reference to the accompanying Drawing, the
manner in which my invention is to be performed.
Figure 1 represents partly in section, and partly in elevation, a knob attached to
a spindle and provided with a screwed covering ring constructed according to my
improvements. Figure 2 shows the covering ring removed from the collar of the
neck, prior to the introduction and driving home of the screw through the said
neck for the attachment of the knob to its spindle. Figure 3 is a cross section of
the knob spindle, and screw head covering ring on the dotted lines A B figure 1.
Figure 4 is the knob separately, showing its screwed collar in elevation, also the

page_text: screwed hole in which the spindle affixing screw takes. Figure 5 is the covering
ring in section, elevation and plan. Figure 6 is an end view of figure 4. Figure 7
represents my improvements applied to Wilkes's spindle. Figure S is a modifi-
cation of the before named figure 1. The knob is affixed to the spindle in this
case, by a partially screwed pin or peg, the plain end of which takes into one or
other of a series of all through holes in the spindle. In this modification, the plain
part of the pin may if necessary be extended into the other side of the neck.
same letters of reference indicate the same parts in the several figures.
The
a is the knob, and b the rose of the said knob. c is an internally screwed, loose
covering ring, provided with a flange c¹ upon its inner side, for preventing the
said ring from screwing too far over the collar on the neck of the knob. d is a
grooved screwed spindle which takes into a screwed hole a² in the axis or bush of
the knob. e is a small affixing screw, which passes through the collar of the neck
of the knob, and terminates in the groove d' running along the spindle.
In affixing the knob a to its spindle d, after the former has been adjusted to the
thickness of door, the small screw e is then passed through the hole a³ in the neck
of the knob with its inner or lower end taking into the longitudinal groove d'
running along the spindle. The head or outer end of the screw or screw pin lying
a little below the surface of the screwed boss or collar a'. Tho internally screwed
covering ring is then screwed upon the screwed part of the neck, when the small
screw or screw pin e² is covered or enclosed, and prevented from rising or becoming
loose, thereby effectually securing the knob to its spindle, as represented in
figures 1, 3, 7 and 8.
The application of my invention to other forms of knobs, spindles and handles,
differs in no essential respect from its application to the knobs and spindles already
described. The improvements herein-before described are also applicable to china,
wood or other non-metallic substances, provided with metallic mounts.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The improvements in securing door and other knobs and handles, by means of
an internally wormed ring or collar, screwing upon the neck of the knob; and
covering or enclosing the head or outer end of the small fixing screw or screw pin;
which said ring or collar when fixed, moves with or becomes a fixture with the
knob, and prevents the fixing screw or screw pin from rising or becoming loose,
thereby effectually securing the knob to its spindle; the parts being arranged,
combined and carried out in the ways and for the purpose as described and
illustrated in figures 1 to 8 both inclusive of the accompanying Drawing.
