IMPROVEMENTS IN ATTACHING KNOBS OR SPINDLES OF DOOR LOCKS AND LATCHES
Year: 1860

page_text: LETTERS PATENT to William Bate, of Wolverhampton, for the Invention
of "IMPROVEMENTS IN ATTACHING KNOBS OR SPINDLES OF DOOR LOCKS AND
LATCHES."
Sealed the 4th October 1860, and dated the 26th April 1860.
PROVISIONAL SPECIFICATION left by the said William Bate, at the Office
of the Commissioners of Patents, with his Petition, on the 26th April
1860.
I, WILLIAM BATE, of Wolverhampton, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN ATTACHING KNOBS TO SPINDLES OF DOOR
LOCKS AND LATCHES," to be as follows:-
My improvements consists in a new and peculiar method of connecting
and attaching the spindles to the knobs of locks and latches so as to permit
of their being used with doors of different and varying thickness, which I
accomplish by providing a series of holes one quarter of an inch apart through
one end of the spindle, through one of which a screw is passed from side to
side of the neck of the knob by this means I obtain a rough adjustment of the
length of spindle. At the opposite end of the spindle I provide another set of
holes, but only one-sixteenth of an inch or less apart, and by securing the other
knob by means of a similar screw passed through one of the closer placed
holes I am enabled to correctly adjust the length of spindle as required.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BATE, of Wolverhampton, send greeting.
WHEREAS Her most Excellent Majosty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of April, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said William Bate, Her special licence that I, the said William Bate, my
executors, administrators, and assigns, or such others as I, the said William
Bate, 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
ATTACHING KNOBS TO SPINDLES OF DOOR LOCKS AND LATCHES," upon the condition
(amongst others) that I, the said William Bate, my executors or administrators,
by an instrument in writing under my, or their, or one of their bands 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Bate, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My Improvements consist in a new and peculiar method of connecting and
attaching the spindles to the knobs of locks and latches so as to permit of
their being used with doors of different and varying thickness ; which I
accomplish by providing a series of holes one quarter of an inch apart through
one of which a screw is passed from side to side of the neck of the knob;
by this means I obtain a rough adjustment of the length of spindle. At the
opposite end of the spindle I provide another set of holes, but only one-
sixteenth of an inch or less apart, and by securing the other knob by means
of a similar screw passed through one of the closer placed holes I am enabled
to correctly adjust the length of spindle as required.

page_text: But the construction and application of my said Invention will bo more
fully explained and understood by the following description thereof.
For fixing a spindle to the knobs I make a series of holes sufficiently large
through the spindle so as to allow a screw which is tapped to fit a screw holo
provided in the neck of the knob, and I prefer to have the said hole tapped
through from side to side so that the screw may have a better hold and be
less liable to become loose and fall out, as is frequently the case where the holo
for the screw is only tapped on one side of the neck of the knob. In making
the holes through the spindle I arrange that the first hole shall be at about one
quarter of an inch from one end, and three or more others of the same kind
at one quarter of an inch apart from centre to centre of each other towards
the centre of the length of the spindle, and I prefer to have them drilled
alternately at right angles to each other so as to reduce the strength of the
spindle as little as possible. At the other end of the spindle I make four
other and similar holes, the first being about one-quarter of an inch from
the end, and the other three holes only one-sixteenth of an inch apart, and,
like the holes at the other end of the spindle, drilled alternately through
the spindle at right angles to each other; and I prefer to employ screws of
tempered steel instead of iron screws as is generally the case, as a much
smaller steel screw may be used having equal strength as a thicker one of
iron.
Having now described the nature of my said Invention, and the manner of
carrying the same into effect. I wish it to be understood that I do not limit
myself to the precise details herein described, as the same may be varied
without departing from the nature of my Invention, but I claim as my
Invention the method of attaching knobs to spindles herein-before described.
In witness whereof, I, the said William Bate, have hereunto set my
band and seal, this Twenty-fifth day of October in the year of our
Lord One thousand eight hundred and sixty.
