Year: 1871

page_text: LETTERS PATENT to Abel Edgar Samels, of Mortlake, in the County
of Surrey, for the Invention of “CERTAIN IMPROVEMENTS FOR ADJUSTING
AND FASTENING DOOR KNOBS OB HANDLES TO LOCK SPINDLES, AND FOR
PREVENTING LATERAL PLAY OR TENDENCY TO BIND IN THE WOODWORK OF
THE DOOR."
Sealed the 8th March 1872, and dated the 3rd November 1871.
PROVISIONAL SPECIFICATION left by the said Abel Edgar Samels
at the Office of the Commissioners of Patents, with his Petition,
on the 3rd November 1871.
I, ABEL EDGAR SAMELS, of Mortlake, in the County of Surrey, do
hereby declare the nature of the said Invention for "CERTAIN IMPROVE-
MENTS FOR ADJUSTING AND FASTENING DOOR KNOBS OR HANDLES TO LOCK
SPINDLES, AND FOR PREVENTING LATERAL PLAY OR TENDENCY TO BIND IN THE
WOODWORK OF THE DOOB," to be as follows:-
To enable the knobs or handles to be efficiently secured and adjusted
on the spindle I form in each knob a hole to receive a hollow

page_text: cylindrical piece of metal having in its interior a screw thread cor-
responding with a thread on the outside of the spindle, and by means of
these screw threads the knob is fastened on the spindle in a very simple
and secure manner, the play required for the handles being regulated
with the greatest nicety. Through the head of the hollow screw I pass
a set screw into a tapped hole in the end of the spindle, this screw being
formed reverse to the hollow one, that is, if the hollow screw was right-
handed the other would be left-handed, and vice versa; and by means of
this set screw the handle is prevented from working loose.
To prevent the follower on the spindle from having lateral play or
tendency to wear away or bend in the woodwork of the door, I use with
my standard improved mortice lock, for which Letters Patent were
granted to me, dated 22nd October 1870, No. 2785, a barrel case
passed through the whole thickness of the door, there being at one end
of the case a flange for fixing it, and in the body a slot to allow the arm
or lever of the follower to work the latch.
To prevent lateral play in ordinary locks I fasten to the sides of the
door small plates having holes to receive collars extending from the
knobs, but when desired these plates may form part of the roses or
washers in which the backs of the knobs work.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Abel Edgar Samels in the Great Seal Patent Office
on the 2nd May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ABEL
EDGAR SAMELS, of Mortlake, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of November, in the year
of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Abel Edgar Samels, Her special
licence that I, the said Abel Edgar Samels, my executors, administrators,
and assigns, or such others as I, the said Abel Edgar Samels, 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

page_text: 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 "CERTAIN IMPROVE-
MENTS FOR ADJUSTING AND FASTENING DOOR KNOBS OR HANDLES TO LOCK
SPINDLES, AND FOR PREVENTING LATERAL PLAY OR TENDENCY TO BIND IN THE
WOODWORK OF THE DOOR," upon the condition (amongst others) that I,
the said Abel Edgar Samels, 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 Abel Edgar Samels, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Figures on the
accompanying Sheet of Drawings, and to the letters of reference marked
thereon (that is to say) :-
This Invention consists in an improved mode of firmly attaching the
knobs or handles of locks to their spindles without depending on the
ordinary imperfect screws in the necks of the knobs, and also in
improved modes of preventing lateral play of the knobs or tendency of
the square spindle to bind in the woodwork of the door.
To enable the knobs or handles to be efficiently secured and adjusted
on the spindle I form in the knob a hole to receive a hollow
cylindrical piece of metal having in its interior a screw thread cor-
responding with a thread on the outside of the spindle, and by means of
these screw threads the knob is fastened on the spindle in a very simple
and secure manner, the play required for the handles being regulated
with the greatest nicety. Through the head of the hollow screw I pass
a set screw into a tapped hole in the end of the spindle, this screw
being formed reverse to the hollow one; that is, if the hollow screw
was right-handed the other would be left-handed, and vice versa; and
by means of this set screw the handle is prevented from working loose.
To prevent the knobs and spindle having lateral play or tendency to
wear away or bind in the woodwork of the door I use with my

page_text: "Standard Improved Mortice Lock," for which Letters Patent were
granted to me, dated 22nd October 1870, No. 2785, a barrel case passed
through the whole thickness of the door, there being at one end of the
case a flange for fixing it, and in the body a slot to allow the arm or
lever of the follower to work the latch.
i
To prevent lateral play in ordinary locks I fasten to the sides of the
door small plates having holes to receive collars extending from the
knobs, but when desired these plates may form part of the roses or
washers in which the backs of the knobs work.
On the accompanying Sheet of Drawings Fig. 1 is a combined 1
sectional and external view of two knobs adapted for an ordinary lock
and formed according to my Invention; Fig. 2 a view of knobs and
barrel case adapted to my "standard improved mortice lock;"
Fig. 3 an outside view, and Fig. 4 a plan, with part in section, of
my "standard lock" without the knobs; and Figs. 5, 6, and 7 are 1
different views of the barrel case for preventing lateral play; and in
Figs. 1 and 2 a represents the knobs and b the lock spindle.
In Fig. 1 the cylindrical piece of metal placed in a hole in the knob
and having an internal screw is marked d, the screw fitting the external
screw e at the end of the spindle c; and in the spindle there is an 2
internal screw, into which is fitted the set screw f, having its head g in
contact with the outer end of the metal piece d; and as before said
when the knob with its metal piece is screwed up as required and the
set screw afterwards screwed tight, the knob is firmly fixed and cannot
be loosened until the set screw is turned back; and although only one 2
of the knobs is shown in section they may be all made in a similar
manner.
In Figs. 2, 3, and 4
represents the follower or lever of my improved
lock, the follower being cast to the collar or barrel i, which is encased in
the barrel case c, Figs. 2, 3, 4, 5, 6, and 7, there being in the case a 3
slot k to allow the play required for the follower to work in, and a
flange to enable it to be fastened to the door by screws.

page_text: Having now described the nature and particulars of my said
Invention, and the manner in which the same is to be performed, I
desire it to be understood, that I claim,-
First. The improved method of securely connecting knobs to lock
spindles by combining the hollow cylindrical screw to work on to the
spindle, and passing the set screw with reverse or left-hand thread
through the head of the cylindrical screw into the lock spindle for
preventing the possibility of the knobs working loose.
And, secondly. The barrel case forming a solid bearing for the follower
and spindle the whole thickness of the door, for effectually securing the
knobs and spindles from any lateral play, as all such improvements
are herein described and illustrated on the accompanying Sheet of
Drawing.
In witness whereof, I, the said Abel Edgar Samels, have hereunto
set my hand and seal, this Twenty-seventh day of April One
thousand eight hundred and seventy-two.
