IMPROVEMENTS IN SECURING KNOBS OR HANDLES TO LOCK SPINDLES, LATCH SPINDLES, CUPBOARD CATCHES, SHUTTER LATCH SPINDLES, & OTHER USES REQUIRING ADJUSTMENT
Year: 1871

page_text: LETTERS PATENT to George Gulliver, of Barnsley, in the County of
York, Ironmonger, for the Invention of "IMPROVEMENTS IN SECURING
KNOBS OR HANDLES TO LOCK SPINDLES, LATCH SPINDLES, CUPBOARD CATCHES,
SHUTTER LATCH SPINDLES, & OTHER USES REQUIRING ADJUSTMENT."
Sealed the 14th November 1871, and dated the 6th July 1871.
PROVISIONAL SPECIFICATION left by the said George Gulliver at the
Office of the Commissioners of Patents, with his Petition, on the
6th July 1871.
I, GEORGE GULLIVER, of Barnsley, in the County of York, Iron-
monger, do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN SECURING KNOBS OR HANDLES TO LOCK SPINDLES, LATCH
SPINDLES, CUPBOARD CATCHES, SHUTTER LATCH SPINDLES, & OTHER USES REQUIRING
ADJUSTMENT," to be as follows:-
This Invention consists in securing the ordinary kobs or handles
of door locks on to plain or smooth square split spindles by inserting
a wedge transversely through the knob, and through the slit in the
spindle, the two sides of which being thus wedged or forced outwards

page_text: cause the knob to be firmly held thereon by frictional contact only.
The interior of the knob and surface of the spindle being both
smooth it follows that the knob can be secured at any given distance
along the spindle, which cannot be accomplished when rack teeth or
screw threads are employed for engaging the spindle with the knob.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Gulliver in the Great Seal Patent Office
on the 4th January 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
GULLIVER, of Barnsley, in the County of York, Ironmonger, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of July, in the year of
our Lord One thousand eight hundred and seventy-one, in the 35th
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Gulliver, Her special license
that I, the said George Gulliver, my executors, administrators, and
assigns, or such others as I, the said George Gulliver, my executors,
administrators, or 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
SECURING KNOBS OR HANDLES TO LOCK SPINDLES, LATCH SPINDLES, CUPBOARD
CATCHES, SHUTTER LATCH SPINDLES, AND OTHER USES REQUIRING ADJUSTMENT,'
upon the condition (amongst others) that I, the said George Gulliver,
my executors or administrators, by an instrument in writing under my
hand and seal, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per-
formed, 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 George Gulliver, do hereby declare
the nature of my said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the accompanying
Drawing, and to the letters and figures marked thereon (that is to
say) :—
My said Invention consists in securing the ordinary knobs or handles
of door locks on to plain or smooth square split spindles by inserting
a wedge transversely through the knob and through the slit in the
spindle, the two sides of which being thus wedged or forced outwards
cause the knob to be firmly held thereon by frictional contact only.
The interior of the knob and the surface of the spindle being both
smooth it follows that the knob can be secured at any given distance
along the spindle, which cannot be accomplished when rack teeth or
screw threads are employed for engaging the spindle with the knob. I
prefer moreover to make the wedge of harder metal than the spindle,
and to form ribs or serrations on the sides thereof in order that it may
take a firmer hold of the inner sides of the spindle.
And in order that the said Invention may be fully understood I shall
now proceed more particularly to describe the same, and for that
purpose shall refer to the several Figures on the annexed Sheet of
Drawings, the same letters of reference indicating corresponding parts
in both the Figures.
Figure 1 of my Drawings represents a side elevation of a lock spindle
to which the knobs are secured by my improved method, one of the
two knobs being shewn in section; Figure 2 is a transverse section
through the knob and spindle.
A is the spindle, and B, B, the knobs or handles to be secured thereon.
This spindle is plain or smooth on its surface, having neither ratchet
teeth or screw threads formed thereon, and has a split or slot a formed
along it at one or both ends. The form of the transverse section of the
spindle is immaterial; I have represented it as square, but it may be
round if preferred. Each knob B has an opening made transversely
through the neck or part which fits the spindle, and into this opening
after the handle has been adjusted on the spindle I drive a wedge b
by preference ribbed on the sides, as shewn, which passes through and
expands or opens out the slotted or split end of the spindle, thereby
effectually tightening the same inside the handle B. The handles can
be casily removed on forcing out the wedge b.

page_text: Having now described and particularly ascertained the nature of the
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is, the mode
of securing the knobs or handles of locks or latches on to smooth or
plain lock spindles by driving a wedge transversely through the neck of
the handle, and through a longitudinal slot or split made in the end
of the spindle, substantially as herein-before described and illustrated
by my Drawings.
In witness whereof, I, the said George Gulliver, have to this my
Specification set my hand and seal, the Thirtieth day of December
One thousand eight hundred and seventy-one.
Witness,
TIMOTHY B. HUNTER.
