Year: 1871

page_text: LETTERS PATENT to Ernest Wentworth Buller, of Hanley, in the
County of Stafford, Earthenware Manufacturer, for the Invention
of "IMPROVEMENTS IN ATTACHING DOOR AND OTHER KNOBS AND HANDLES TO
SPINDLES."
Sealed the 11th July 1871, and dated the 26th January 1871.
PROVISIONAL SPECIFICATION left by the said Ernest Wentworth
Buller at the Office of the Commissioners of Patents, with his
Petition, on the 26th January 1871.
I, ERNEST WENTWORTH BULLER, of Hanley, in the County of Stafford,
Earthenware Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN ATTACHING DOOR AND OTHER KNOBS AND.
HANDLES TO SPINDLES," to be as follows:-
.My Invention consists of the construction and arrangement or
combination of parts herein-after described for attaching door and other
knobs and handles to spindles.

page_text: By my Invention the knobs and handles are attached to their spindles
and adjusted thereon to the thickness of the door or other surface with
great facility. Besides facility of attachment and adjustment my
Invention is inexpensive.
According to my Invention I make the square spindle of the knob or
handle tubular, the said tubular spindle receiving the end of the fixing
screw of the knob or handle. The said tubular spindle is made by
preference, by a drawing process, or the said tubular spindle may be
made by casting or by drilling a hole longitudinally in a solid spindle.
In applying my Invention to the attaching of the moveable knob of a
pair of door knobs to its spindle and adjusting it on its spindle to the
thickness of the door I combine with a tubular spindle the following
parts-The square tubular spindle is secured to the fixed knob in the
ordinary way. The exterior of that end of the spindle upon which the
moveable knob is placed is screwed at its angles, as usual, to receive an
adjustable screw nut or collar, as herein-after described. The interior of
the said end of the tubular spindle is provided with a hollow or concave
screw, into which the fixing screw herein-after described of the moveable
knob takes. In the moveable knob is an axial hole passing from front to
back, and in the neck of the knob and in the axial hole described is a
square tube carried by a metallic mount fixed to the knob. The outer
end of the said square tube projects a short distance from the face of the
mount.
In fixing the moveable knob to and adjusting it on the tubular
spindle the said spindle having the fixed knob on one end is passed
through the door, and upon the protruding screwed end of the said
spindle a screw nut or collar is screwed until it abuts against the surface
of the door. In the outer face of this screw nut or collar a square
depression or recess is made. On placing the moveable knob on the
screwed end of the spindle and pushing the said knob towards the door
the projecting end of the square tube in the neck of the said knob takes
into the depression or recess in the screw nut or collar and prevents its
rotation on the spindle. The knob thus adjusted on the spindle is fixed
to the spindle by means of a screw pin. This fixing screw pin has a
long screwed stem and a large ornamental head. By passing the said
stem down the axial hole in the knob from the front thereof and screwing
it into the screwed end of the tubular spindle the adjusted knob is

page_text: securely fixed on the said spindle. By withdrawing the fixing screw pin
the knob may be removed from the spindle by a sliding motion.
The application of my Invention to knobs other than door knobs
and to handles differs in no essential respect from its application to door
knobs.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Ernest Wentworth Buller in the Great Seal Patent
Office on the 24th July 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ERNEST
WENTWORTH Buller, of Hanley, in the County of Stafford, Earthenware
Manufacturer, send greeting.
'
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of January, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Ernest Wentworth Buller, Her special
licence that I, the said Ernest Wentworth Buller, my executors, admi-
nistrators, and assigns, or such others as I, the said Ernest Wentworth
Buller, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN ATTACHING DOOR AND OTHER KNOBS AND HANDLES TO SPINDLES,"
upon the condition (amongst others) that I, the said Ernest Wentworth
Buller, my executors or administrators, by an instrument in writing.
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Ernest Wentworth Buller, do hereby
dealove the nature of the said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained.in and
by the following statement thereof, that is to say :-
My Invention consists of the construction and arrangement or com-
bination of parts herein-after described for attaching door and other
knobs and handles to spindles.
By my Invention the knobs and handles are attached to their spindles,
and adjusted thereon to the thickness of the door or other surface with
great facility. Besides facility of attachment and adjustment my Inven-
tion is inexpensive.
According to my Invention I make the square spindle of the knob or
handle tubular, the said tubular spindle receiving the end of the fixing
screw of the knob or handle. The said tubular spindle is made by
preference by a drawing process, or the said tubular spindle may be
made by casting or by drilling a hole longitudinally in a solid spindle.
In applying my Invention to the attaching of the moveable knob of a
pair of door knobs to its spindle, and adjusting it on its spindle to the
thickness of the door, I combine with a tubular spindle the following
parts: The square tubular spindle is secured to the fixed knob in the
ordinary way. The exterior of that end of the spindle upon which the
moveable knob is placed is screwed at its angles as usual to receive an
adjustable screw nut or collar, as herein-after described. The interior of
'the said end of the tubular spindle is provided with a hollow'or concave
screw, into which the fixing screw herein-after described of the moveable
knob takes. In the moveable knob is an axial hole passing from front
to back and in the neck, and in the axial hole described is a square tube
carried by a metallic mount fixed to the knob. The outer end of the
said square tube projects a short distance from the face of the mount.
In fixing the moveable knob to and adjusting it on the tubular spindle
the said spindle having the fixed. knob on one end is passed through the
door, and upon the protruding screwed end of the said spindle a screw
nut or collar is screwed until it abuts against the surface of the door.
In the outer face of this screw nut or collar a square depression or recess
is made. On placing the moveable knob on the screwed end of the
spindle and pushing the said knob towards the door the projecting end
of the square tube in the neck of the said knob takes into the depression
or recess in the screw nut or collar, and prevents its rotation on the
spindle. The knob thus adjusted on the spindle is fixed to the spindle

page_text: by means of a screw pin. This fixing screw pin has a long screwed
stem and a large ornamental head. By passing the said stem down the
axial hole in the knob, from the front thereof and screwing it into the
screwed end of the tubular spindle the adjusted knob is securely fixed on
the said spindle. By withdrawing the fixing screw pin the knob may be
removed from the spindle by a sliding motion.
The application of my Invention to knobs other than door knobs and
to handles differs in no essential respect from its application to door
knobs.
Having explained the nature of my Invention, I will proceed to
describe, with reference to the accompanying Drawing, the manner in
which the same is to be performed.
Figure 1 represents partly in elevation and partly in longitudinal
section a pair of door knobs, the moveable knob of which is adjusted on
and attached to its spindle according to my Invention; Figure 2 repre-
sents the spindle and fixed knob separately; Figure 4 represents the
moveable knob separately; Figure 3, the adjustable screw nut or collar
separately; and Figure 5, the fixing screw separately. The same letters
of reference indicate the same parts.
a is the fixed knob secured to the spindle b in the usual way. The
said spindle b is screwed externally as usual, and is tubular at that end
which receives the moveable knob c. The interior of the tubular end of
the spindle is provided with a hollow or concave screw d. In the
moveable knob c is an axial hole e, through which the fixing screw f
passes. The end g² of the square tube of the metallic mount a projects
from the face of the said mount, as best seen in Figure 3. is the
adjustable screw nut or collar working on the screwed end of the
spindle b.
In the face of the said screw nut or collar h is a square
depression or recess ³ of a size proper to receive the projecting end g² of
the square tube of the mount g. i is the rose of the fixed knob, and k
is the rose of the moveable knob. The moveable knob c is adjusted on
and attached to its spindle in the following manner:-The spindle b
with the fixed knob a on one end is passed through the door, so that its
screwed end protrudes from the said door. Upon the projecting screwed
end of the spindle 6 the rose k is first placed and fixed to the door in the
usual way, the said rose having the ordinary back plate ². The
adjustable screw nut or collar his next screwed on the spindle until it

page_text: b
enters the rose and abuts against the back plate k³ of the said rose; the
moveable knob c is then placed on the spindle and pushed towards the
door. The projecting end g² of the square tube of the mount is thereby
made to take into the square depression or recess in the adjustable
screw nut or collar h, and prevent the said nut or collar rotating on the
spindle. The adjusted knob c is next fixed to the spindle 6 by passing
the screw down the axial hole.d in the knob c from the front thereof,
and screwing it into the screwed end d of the tubular spindle 6, as illus-
trated in Figure 1. The adjusted knob c is thereby securely fixed on its
spindle. By unscrewing the screw the knob c may be withdrawn by a
sliding motion from the spindle b. When the spindle is made of iron I
prefer to use a solid spindle, and make the fixing screw tubular to screw
upon the exterior of the solid spindle. This modification of my Invention
is illustrated in longitudinal section in Figure 6, and cross section in
Figure 7. Figure 8 represents in elevation and section the tubular
fixing screw separately; the tubular fixing screw is marked f, the
screwed internal part being marked f². The other parts of this arrange-
ment are the same as those of the arrangement herein-before described,
and corresponding parts are marked with the same letters of reference.
In fixing the adjusted moveable knob c, Figure 6, by the use of the
tubular fixing screw the screwed end f2 of the said screw takes on to
the external screw of the solid spindle b, instead of the solid fixing screw
taking into the tubular screwed spindle, as in Figure 1.
The knobs and handles besides door knobs and handles to which my
Invention may
be applied are, among others, the knobs or handles of
shutter and cupboard turnbuckles.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I do
not limit myself to the precise details herein described and illustrated, as
the same may be varied without departing from the nature of my
Invention; but I claim as my Invention,―
Firstly. The combination or arrangement of parts herein-before
described and illustrated in Figures 1, 2, 3, 4, and 5, of the accom-
panying Drawing for attaching door and other knobs and handles to
spindles, that is to say, the combination of a solid axial fixing screw
with a tubular spindle screwed externally and internally, substantially
as described and illustrated.

page_text: Secondly. The combination or arrangement of parts herein-before
described and illustrated in Figures 6, 7, and 8 of the accompanying
Drawing, for attaching door and other knobs and handles to spindles,
that is to say, the combination of a tubular axial fixing screw with a
screwed solid spindle, substantially as described and illustrated.
Thirdly. Preventing the rotation of the adjustable screw nut or collar
on its spindle by making a square tubular part on the face of the knob
take into a square recess or depression in the said screw nut or collar, sub-
stantially as herein-before described and illustrated in Figures 1, 3, 4, and
6 of the accompanying Drawing.
In witness whereof, I, the said Ernest Wentworth Buller, have
hereunto set my hand and scal, this Twenty-first day of July,
in the year of our Lord One thousand eight hundred and seventy-
one.
Witness,
ERNEST WENTWORTH BULLER. (L.S.)
