IMPROVEMENTS IN CERTAIN DESCRIPTIONS OF KNOBS FOR BEDSTEADS, DOOR HANDLES, AND OTHER SIMILAR PURPOSES
Year: 1869

page_text: LETTERS PATENT to Thomas Kendrick, of Birmingham, in the County
of Warwick, Manufacturer, for the Invention of "IMPROVEMENTS IN
CERTAIN DESCRIPTIONS OF KNOBS FOR BEDSTEADS, DOOR HANDLES, AND OTHER
SIMILAR PURPOSES."
Sealed the 22nd December 1869, and dated the 10th July 1869.
PROVISIONAL SPECIFICATION left by the said Thomas Kendrick at the
Office of the Commissioners of Patents, with his Petition, on the
10th July 1869.
I, THOMAS KENDRICK, of Birmingham, in the County of Warwick,
Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN CERTAIN DESCRIPTIONS OF KNOBS FOR BEDSTEADS, DOOR
HANDLES, AND OTHER SIMILAR PURPOSES," to be as follows:-
My Invention refers more particularly to knobs formed of china,
composition, or wood, and it consists in fitting in the neck of the knob
a metal bush or socket peculiarly formed and having its centre part

page_text: tapped, screwed, or otherwise suitably punched, bored through, or cast
for attachment to the screws upon the pillars of metallic bedsteads, the
spindles of door handles, or for other like purposes.
The bush or socket is either angular, oval, or round in plan, and of
suitable depth to admit of tapping or otherwise boring, as described,
and may be formed with a face, flange, or rim surrounding the top
edge. When the bush or socket is round in plan it is furnished with
one, two, or more bolts or flanges projecting from the sides and at right
angles to the face flange. Countersinkings or recesses are formed in the
neck of the knob corresponding in shape and size to and for receiving
the bush or socket. The object of the bolts or side flanges is to secure
the turning of the handle and the bush or socket at the same time
by thus locking the parts together. The side flanges may however be
dispensed with in forming the bush or socket or the face flange angular
in plan, the locking of the parts being obtained by the fitting of the
angles in their countersinkings in the knob. The securing of the bush
or socket in its position in the knob may be effected as circumstances
require, such as by means of a metal shell or cap fitting over and upon
the face of the bush or socket and turned over the neck of the knob
or by means of a pin passing through the length of the knob or by
cement. The bushes or sockets as described may be formed of any
suitable metal by casting, raising, or other convenient method.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Kendrick in the Great Seal Patent Office
on the 10th January 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
KENDRICK, of Birmingham, in the County of Warwick, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of July, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Kendrick, Her special license
that I, the said Thomas Kendrick, my executors, administrators, and

page_text: assigns, or such others as I, the said Thomas Kendrick, 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 "IMPROVEMENTS
IN CERTAIN DESCRIPTIONS OF KNOBS FOR BEDSTEADS, DOOR HANDLES, AND OTHER
SIMILAR PURPOSES," upon the condition (amongst others) that I, the said
Thomas Kendrick, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said
Iuvention, 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 Thomas Kendrick, do hereby declare
the nature of the said Invention, and in what mauner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the Drawings hereunto
annexed, and to the letters and figures marked thereon, that is to
say:
My Invention refers more particularly to knobs formed of china,
composition, or wood, and it consists in fitting in the neck of the knob a
metal bush or socket peculiarly formed, and having its centre part
tapped, screwed, or otherwise suitably punched, bored through, or cast
for attachment to the screws upon the pillars of metallic bedsteads, the
spindles of door handles, or for other like purposes.
Referring to the Drawings the group, Figure 1, represent a bush or
socket formed round in plau and of suitable depth to admit of tapping
or otherwise boring, having a face, flange, or rim (a) surrounding the
top edge, and furnished with bolts or side flanges (6) projecting from
the sides at right angles to the face flange (a).
Figure 2 is a plan of a knob for a bedstead or other similar use
formed of china, composition, or wood having countersinkings or recesses
(c) corresponding to and for the reception of the bush or socket, Figure 1.
The object of the bolts or side flanges (b) is to secure the turning of
the knob or handle, as the case may be, and the bush or socket at the
same time by thus locking the parts together.

page_text: Figure 3 represents in part sectional elevation the bush or socket fitted
in the neck of the knob, formed as described to receive it. (d) is a screw
or spindle by which the knob is secured to the pillar of a bedstead or
for other like purpose..
The securing of the bush or socket in its position in the knob may
be effected as circumstances require, such as by means of a metallic
shell or cap (e) fitting over and upon the face of the bush or socket
and turned over the neck of the knob, as shewn in elevation, Figure (4)
or by means of a pin passing through the knob or by cement; in securing
the knob to a spindle for forming a door handle, it may be found
preferable to bore, punch, or cast the centre part of the bush or socket
square or angular instead of circular as shewn.
Figure 5 shews in an under side view a bush or socket having only
one bolt or flange (6) for the purpose described; any suitable number
of the bolts or flanges may however be employed according to the
strength or rigidity of the parts required.
Figure 6 is a plan of another form of bush or socket having four side
bolts or flanges (f), the face flange or rim (a), shewn in Figure 1, being
dispensed with; or as illustrated in a side view, Figure 7, the bolts or
flanges (9) may extend only a portion of the depth of the bush or
socket if desired; again, as represented in Figure 7, the bush or socket.
may be formed as part of or be attached to the metallic shell or cap (e);
or again, I sometimes purpose dispensing with the side bolts or flanges.
and form the bush or socket oval in plan, as shewn in Figure 8, in a
portion or all of its depth, or angular, such as Figure 9, which is similar
to an ordinary tapped nut, Figure 10, shewing in side elevation the
angular part (h) as a face plate and not formed the entire depth of the
bush or socket, or the bush or socket may have its lower part angular
in plan with a circular face plate surrounding the top edge and similar
to (a), Figure 1.
The bushes or sockets, as described, may be formed of any suitable
metal by casting, raising, or other convenient method.
Having thus described the object and nature of my said Invention;
and the manner in which the same is to be carried into effect, I claim
without limiting myself to these precise details the several improvements
in knobs for bedsteads, door handles, and other similar purposes, and

page_text: in bushing or mounting the same, as herein more fully set forth and
specified.
In witness whereof, I, the said Thomas Kendrick, have hereunto
set my hand and seal, this Seventh day of January, in the year
of our Lord One thousand eight hundred and seventy.
THOMAS KENDRICK. (L.S.)
