IMPROVEMENTS IN LOCK SPINDLES
Year: 1852

page_text: LETTERS PATENT to Edward Lambert Hayward, of the Black-
friars Road, in the County of Surrey, for the Invention of
IMPROVEMENTS IN LOCK SPINDLES."
Sealed the 8th January 1853, and dated the 1st October 1852.
PROVISIONAL SPECIFICATION left by the said Edward Lambert
Hayward at the office of the Commissioners of Patents, with his
petition, on the 1st October 1852.
I, EDWARD LAMBERT HAYWARD, of the Blackfriars Road, in the
County of Surrey, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN LOCK SPINDLES" to be as follows:---
The general mode of adjusting the length of lock spindles has here-
tofore been by means of recesses formed in the sides of the spindles, by
which only comparative nice adjustment is obtained.
Now this Invention consists of forming. holes through one end of a
spindle, the other end being formed with a slot through it, into which a
screw passes, by which a very nice and ready adjustment of the length
is obtained.

filed by the said Edward Lambert Hayward, in the Great Seal
Patent Office, on the 30th March 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
EDWARD LAMBERT HAYWARD, of the Blackfriars Road, in the County of
Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of October in the year of our
Lord One thousand eight hundred and fifty-two, in the sixteenth year
of Her reign, did for Herself, Her heirs and successors, give and grant
unto me, the said Edward Lambert Hayward, Her special licence that
I, the said Edward Lambert Hayward, my executors, administrators,
and assigns, or such others as I, the said Edward Lambert Hayward,
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
LOCK SPINDLES," upon the condition (amongst others) that I, the said
Edward Lambert Hayward, 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 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 Edward Lambert Hayward, do
hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement thereof (that is to say):
The general mode of adjusting the length of lock spindles has here-
tofore been by means of recesses formed in the sides of the spindles, by
which only comparative nice adjustment is obtained.
Now this Invention consists of forming holes through one end of a
spindle, the other end being formed with a slot through it, into which a

page_text: Figure 1, shows a section of part of a door having two knobs or
handles, and spindle applied thereto, and Figure 2, shows two views of
a spindle separately; a, is the part of the door; b, b, are two knobs or
handles, and the spindle c, is formed and adjusted in the following man-
It has at one end a series of holes, c', as is shown, which are
similar to what have heretofore been used; into one of these holes. (ac-
cording to the thickness of the door) the screw d, will enter, and it should
be the one which will leave as little requirement for adjustment at the
other end of the spindle as may be, because it is at the other end that
the nice adjustment of the length is to be obtained; c, is a slot, and c³,
a screw which enters the slot from that end of the spindle, and it is
against the end of this screw c³, that the screw-pin e, comes when it is
introduced into its place.
It will be understood that if the screw c³, does not enter sufficiently
into the slot, that the handles would not be close up to their positions,
and the same would be loose; and on the other hand, if the screw c³, is
screwed too far into the slot, the screw-pin e, would not pass through the
slot in the spindle; hence it should be understood that the screw c', should
only be screwed into the slot to such an extent as to ensure the screw-
pin e, coming against its end, leaving the handles or knobs only so much
play that they may turn with the spindle with ease, and not offer too
much friction to the spring in the lock.
I would remark, that in place of having the slot at only one end, it is
evident that in place of having the several holes a slot and screw may
be used at both ends of the spindle.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that I do not con-
fine myself to the precise details herein shown and described, so long as

page_text: the peculiarity of the Invention be retained; but what I claim is the
combination or construction of lock spindles herein described.
In witness whereof, I, the said Edward Lambert Hayward, have
hereunto set my hand and seal, this Twenty-third day of March
in the year of our Lord One thousand eight hundred and
fifty-three.
EDWARD L. HAYWARD. (L.S.)
Witness, S. CARPMAEL.
