PROVISIONAL SPECIFICATION.
Improvements in or in connection with Door and like Knobs.
We, WILLIAM BLACKBAND, of Northview, Newport, Grocer, and HENRY
EDWARD AUDLEY CHARLES, of the Cottage, Newport, Electrical Engineer, both
in the County of Salop, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to the mode of fastening door knobs and similar articles,
and its object is to arrange a more secure fastening than those in present use and
at the same time make a cheap and effective knob.
In door knobs constructed in one manner in accordance with our invention, we
secure one knob to the spindle by a screwed thread in the knob or in a piece of
metal or other suitable material within the knob, and we lock the said screw by a
lock nut let in from the external surface of the knob.
We do not screw the second knob, but we arrange it to slide on the square
spindle and provide an aperture through which the said spindle passes; we screw
the end of the spindle and on it we thread a screwed cap or nut. We provide this
nut with an external flange of square reticulated or angular configuration and
cause it to fit into a recess of similar configuration in the external surface of
the knob.
We apply the knob in the following manner :-first we slip through the spindle
having a first knob fastened on end as described, and then we thread a washer over
the spindle and follow with the second knob which we press home against the door.
We then screw home the screwed cap on the end of the spindle, and when screwed
home the external flange is clear of the knob and recess; we then pull out the
knob slipping the reticulated or angular flange into the corresponding recess, and
we secure the knob in its out position by slipping in between the door and the
continuous flange already hereinbefore described a flange with a side gap or a
flange in two halves. We secure the said flange to the door and to the continuous
flange by screws or other fastenings. When a gap flange is employed we fill up
the gap with a gap piece also screwed home.
The first knob or knob carrying the spindle with it may be attached in several
ways and have an internal screw nut within the knob while the square of the
spindle fits another part. Or any well known method may be used for this knob.
The internal screw may be rotated from without by means of a suitable aperture
and a convenient insertion tool. Or the knob may be made in two halves fitting
loosely against a socket carrying the square with a suitable split flange and a
double pin or key to insert between the two halves to cause them to rotate
together.
Instead of making the second knob with a nut and recess, we may construct the
knob in two halves and arrange the outer half as the nut. In this case we check
the outer half upon or within the inner and recticulate the internal edges so that
when the inner half carrying the square is pulled out it fits into the reticulations
and is then secured by the insertion of the split or cut washer between a flange and
the door as hereinbefore described.
The two halves may be secured together by a plain key, dowel, screw, or pin
instead of the reticulations if desired.
Other arrangements may be adopted to secure a nut within a knob; the nut may
be inserted. before the two halves of the knob are attached in any well known
manner and the lap joint of the two halves may be closed by the operation of
spinning while the nut is within,

page_text: The surface of the nut may be checked, roughened or corrugated to grip the
knob so that it may rotate with it and fit against the part containing the square.
The knob may be made of solid material such as china or vulcanized rubber in
which case it fits the square of the spindle or is dowelled or checked on the collar
part of metal which fits the square spindle.
Dowels are used to attach the solid knob part to the collar part.
Any convenient material may be used for the washers and continuous flange.
The same methods may be applied to knobs used for bedsteads or other purposes
where knobs are required.
By another method we construct a simple attachment for door knobs by forming
the bolt with a square or other reticulated head, and this head we allow to fit flush
into one of the handles or knobs, while the opposite end of the bolt we form as a
screw to receive a nut having a similarly shaped exterior which we cause to fit into
a suitably shaped recess formed within the handle; but in order to prevent the
nut from working loose by the movement of the handle, we place a washer over
the screwed square end of the bolt which washer also fits the recess within the
handle. The outer surface of the nut we may cover with a disc of metal or a plug
or disc of any suitable material.

COMPLETE SPECIFICATION.
Improvements in or in connection with Door and like Knobs.
We, WILLIAM BLACK BAND, of Northview, Newport, Grocer, and HENRY
EDWARD AUDLEY CHARLES, of the Cottage, Newport, Electrical Engineer, both
in the County of Salop, 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:-
Our invention relates to the mode of fastening door knobs and similar articles
and its object is to arrange a more secure fastening than those in present use and
at the same time make a cheap and effective knob.
In the two accompanying sheets of explanatory drawings, we illustrate different
methods of constructing our improved door knobs.
In door knobs constructed in one manner in accordance with our invention as
shown in sectional elevation at Figure 1 we secure one knob A to the spindle B by
a screwed thread a in the knob or in a piece of metal or other suitable material
within the knob and we lock the said screw by a lock nut C let in from the external
surface of the knob.
We do not screw the second knob A' but we arrange it to slide on the square
spindle and provide an aperture through which the said spindle passes; we screw
the end of the spindle and on it we thread a screwed cap or nut D. We provide
this nut D with an external flange d of square, reticulated or angular configuration
as shown in Figure 2, and cause it to fit into a recess of similar configuration in the
external surface of the knob A¹. We apply the knob in the following manner-
first we slip through the spindle B having a first knob A fastened on one end as
described and then we thread a washer E over the spindle and follow with the
second knob which we press home against the door. We then screw home the
screwed cap D on the end of the spindle, and when screwed home the external
flange d is clear of the knob A' and recess; we then pull out the knob A¹ slipping
the reticulated or angular flange into the corresponding recess and we secure the
knob in its out position by slipping in between the door and the continuous flange
already herein before described a flange with a side gap or a flange E' in two halves
as shown in Figure 3. We secure the flauge E or E¹ to the door and to the

page_text: continuous flange by screws e or other fastenings. When a gap flange is employed
we fill up the gap with a gap piece also screwed home.
The first knob A or knob carrying the spindle B with it may be attached in
several ways and have an internal screw nut C¹ within the knob as shown at
Figure 4 while the square of the spindle fits another part; or any well known
method may be used for this knob. The internal screw may be rotated from with-
out by means of a suitable aperture and a convenient insertion tool. Or the knob
may be made in two halves fitting loosely against a socket carrying the square with
a suitable split flange and a dowel pin or key to insert between the two halves to
cause them to rotate together.
Instead of making the second knob with a nut and recess we may construct the
knob F in two halves and arrange the outer half F1 as the nut as shown in Figure 5.
In this case we check the outer half F¹ upon or within the inner F and reticulate
the internal edges so that when the inner half carrying the square is pulled out it
fits into the reticulations and is then secured by the insertion of the split or cut
washer E between a flange and the door as hereinbefore described.
The two halves may be secured together by a plain key, dowel, screw, or pin
instead of the reticulations if desired.
Other arrangements may be adopted to secure a nut within a knob; the nut G
and G¹ may be inserted as shown in Figure 6 and Figure 7 before the two halves H, H'
of the knob are attached in any well known manner and the lap joint h of the
two halves may be closed by the operation of spinning while the nut G and G¹
is within.
The surface of the nut G¹ may be checked, roughened or corrugated to grip the
knob or it may be pegged to it as at G so that it may rotate with it and fit against
the part containing the square.
The knob I may be made of any solid material such as glass, wood, china or
vulcanized rubber in which case it fits the square of the spindle B as shown in
Figure or is doweled by dowels M¹ or checked on the collar part M of metal
which fits the square spindle B. The knob L we secure by means of our nut D and
the washer E fills up the space between the knob and door.
Figure 9 is a sectional elevation of our knob N formed of wood or like material
and having the collar part M of metal to attach to it by pins or screws n; the nut o
we prefer to attach to the knob N by screws as shown.
Any convenient material may be used for the washers and continuous flanges E.
By another method we construct a simple attachment for door knobs by forming
the bolt B' as shown in Figure 10 Sheet 2 with a square or other reticulated head B³
and this head we allow to fit flush into one of the handles or knobs A2, while the
opposite end of the bolt 6' we form as a screw to receive a nut D* having a similarly
shaped exterior which we cause to fit into a suitably shaped recess formed within
the handle; but in order to prevent the nut from working loose by the movement
of the handle we place a washer R over the screwed square end of the bolt which
washer also fits the recess within the handle. The outer surface of the nut we may
cover with a disc of metal S or a plug or disc of any suitable material.
The same methods may be applied to knobs used for bedsteads or other purposes
where knobs are required.
Figures 11 and 12 are plans of the washers E³ which we sometimes employ as
shown in sectional elevation at Figure 13, and in plan at Figure 14 and Figure 15
This washer E³ permits of a thin cover plate or washer E being employed so as
to screw down and shield it when in position. The handle knob T Figure 13 we
construct out of sheet metal spinning T¹ into T, and placing the nut G2 within it
before doing so; the bottom end of the collar T2 being placed so; as to permit of
thin material being employed throughout.
Figure 16 is a sectional elevation of another form of sheet metal handle U with
the nut G³ carried within it to form a body or case to receive the knob portion U,
a washer or collar T being provided to give a good bearing surface.
Figure 17 is a sectional elevation of a stronger form of wronght metal handle

page_text: having a supporting plate V within the knob V¹ the nut G being carried upon
the plate V and within the body of the handle so as to rest upon the collar V³.
To permit of the wear of the spindle being taken up we sometimes employ a
tapered spindle B³ as shown in Figure 18, and we prefer to use a nut W having
preferably a number of projecting bars as shown in Figure 19 to enable the screw
to be tightened by placing a nail or other article against one of the teeth like bars
to press it round.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is-
1. The construction of door knobs and the like having a nut or washer contained
in one portion of the handle or knob to secure the spindle passing from the knob or
handle on the opposite side of the door, and having a split or slotted make up washer
to place between the door and the end of the handle or handles, substantially as
herein before described.
2. The construction of a door knob and handle having the spindle such as B pro-
vided with heads for entering one knob and having a nut such as D³ for securing
the same to the other knob substantially as herein before described and as illustrated
in Figure 10 of the accompanying drawings.
3. The construction of door knobs and handles from metal, with spindles, nuts
and fastenings for the same substantially as hereinbefore described and as illustrated
in Figures 1, 4, 5, 6, 7 and 13 of the accompanying drawings.
4. In a door knob or handle the construction and arrangement of a split or slotted
washer such as E', Es substantially as and for the purposes hereinbefore described
and as illustrated in the accompanying drawings.
