Year: 1863

page_text: LETTERS PATENT to Isaac Parker, of Haughton Street, Clare Market,
in the County of Middlesex, Machinist, for the Invention of "IMPROVE-
.MENTS IN CONNECTING AND SECURING DOOR AND OTHER KNOBS OR HANDLES
TO THEIR SPINDLES."
Sealed the 10th November 1863, and dated the 14th May 1863.
PROVISIONAL SPECIFICATION left by the said Isaac Parker at the
Office of the Commissioners of Patents, with his Petition, on the
14th May 1863.,
I, ISAAC PARKER, of Haughton Street, Clare Market, in the County of
Middlesex, Machinist, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN CONNECTING AND SECURING DOOR AND OTHER KNOBS OR HANDLES
TO THEIR SPINDLES," to be as follows:-
This Invention has for its object improvements in the methods adopted for
securing and attaching door or other knobs or handles to their spindles, so
'as to prevent such knobs or handles from becoming detached from their
spindles either by accident or design; and in carrying out my improvements I
take a spindle screwed from end to end with a suitable screw, the sides being
squared down, as is well known and practiced with door spindles of other
constructions. I use door knobs or handles of ordinary and well-known shapes
and materials, and upon one of such knobs or handles (which by preference F
place outside the door) I fix a plate of brass or other suitable metal or
material, which plate is perforated with one or more holes (or such holes ar

page_text: recesses may be formed in the knob or handle itself when made of suitable
material) towards its outer edge, and having a central hole screwed inside, into
which the spindle screws as far as required. Sliding on the spindle by means of
a square hole, but not turning round thereon, is a loose plate of suitable
thickness, and (by preference) of the same diameter as the plate attached to the
knob, and in the body thereof towards the outer edge there are one or more
studs or pins which take into and fit the hole or holes in the plate in the door
knob or handle. Other means may be adopted for catebing or locking this plate
to the plate fixed on the door handle or knob, but I prefer to employ the means
above described. On the other knob or handle, which by preference I place
inside the door, a plate of brass or other suitable metal or material is fixed as
before, but instead of a hole or holes in such plate or knob (when the plate
forms part of the knob) a square or oblong stud is fixed, which stud is made
by preference of the same size as the square on the spindle. A plate or disc is
attached to this knob, which plate is cut nearly across by a slot of similar
width to the square of the spindle, and at one end of the slot a round opening
is formed wherein the spindle. revolves when required, and when in position it
slides on the square stud above referred to. When fixing the knob on to the
spindle the plate is slid sideways till the spindle revolves in the circular part of
the slot, and the knob is screwed as far on as may be required; the plate is
then pressed down on the stud until it comes to be concentric with the plate
on the knob, when the slot then fits the square on the spindle, and causes the
spindle to turn round on moving the knob or handle; the plate may be.
secured to or prevented from sliding upon the knob by means of a cover plate
screwed on to the door, or by set screws or other suitable means.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
. by the said. Isaac Parker in the Great Seal Patent Office on the 14th
November 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ISAAC
PARKER, of Haughton Street, Clare Market, in the County of Middlesex, s
Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of May, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto s
me, the said Isaac Parker, Her special licence that I, the said Isaac

page_text: Parker, my executors, administrators, and assigns, or such others as I, the
said Isaac Parker, 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 CONNECTING AND SECURING DOOR AND OTHER KNOBS OR HANDLES
TO THEIR SPINDLES," upon the condition (amongst others) that I, the said
Isaac Parker, 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 Isaac Parker, do hereby declare the
nature of the 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 thereof, that is to say:-
"
This Invention has for its object improvements in the methods adopted for
securing and attaching door or other knobs or handles to their spindles, so as
to prevent such knobs or handles from becoming detached from their spindles
either by accident or design; and in carrying out my improvements I take a
spindle screwed from end to end with a suitable screw, the sides being squared
down, as is well known and practiced with door spindles of other constructions.
I use door knobs or handles of ordinary and well-known shapes and materials,
and upon one of such knobs or handles (which by preference I place outside
the door) I fix a plate of brass or other suitable metal or material, which plate
is perforated with one or more holes (or such holes or recesses may be formed
in the knob or handle itself when made of suitable material) towards its outer
edge, and having a central hole screwed inside, into which the spindle screws
as far as required. Sliding on the spindle by means of a square hole, but not
turning round thereon, is a loose plate of suitable thickness, and (by pre-
ference) of the same diameter as the plate attached to the knob, and in the
body thereof towards the outer edge there are one or more studs or pins
which take into and fit the hole or holes in the plate in the door knob or.
handle. Other means may be adopted for catching or locking this plate to
the plate fixed on the door handle or knob, but I prefer to employ the
means above described. On the other knob or handle, which by preference I
place inside the door, a plate of brass or other suitable metal or material is

page_text: fixed as before, but instead of a hole or holes in such plate or knob (when the
plate forms part of the knob), a square or oblong stud is fixed, which stud is
made, by preference, of the same size as the square on the spindle. A plate
or disc is attached to this knob, which plate is cut nearly across by. a slot of
similar width to the square of the spindle, and at one end of the slot a round
opening is formed wherein the spindle revolves when required, and when in
position it slides on the square stud above referred to. When fixing the knob
on to the spindle the plate is slid sideways till the spindle revolves in the
circular part of the slot, and the knob is screwed as far on as may be
required; the plate is then pressed down on the stud until it comes to be
concentric with the plate on the knob, when the slot then fits the square on
the spindle, and causes the spindle to turn round on moving the knob or
handle; the plate may be secured to or prevented from sliding upon the knob
by means of a cover plate screwed on the door, or by set screws or other
suitable means.
And in order that my Invention may be most fully understood and
readily carried into practice, I will proceed to describe the Drawing hereunto
par
connected and secured to their spindle according to my Invention, some of the
parts being shown separately and marked with corresponding letters of.
reference.
a is a square spindle, having a screw thread cut on the angular edges thereof,
the knobs or handles b, c, being formed with female screw sockets to fit the screw
thread cut on the spindle a. The inner face or plate b¹ of the knob 6 (which I
will call the outside knob of the door to which the pair of knobs and spindles are
applied) is formed with a series of holes or recesses, into which a stud or pin d'
on the plate d is arranged to enter, and thus connect the two parts together.
The plate d is formed with a square hole in the centre so as to fit and slide
upon the spindle a, and until the pin or stud d' on the plate d enters one of
the holes formed to receive it in the knob or plate 6', the knob is free to
revolve and be screwed on to or off from the spindle a, but when the knob b
and the plate d are in contact so that the pin or stud d' on the plate d enters
on of the holes in the knob or plate b¹ to connect them together, then the knob
or bandle 6 cannot be moved to the right or to the left without causing the
spindle a to partake of the same movement. On the inner face or plate c¹ of
the knob c (placed on the inside of the door) a square or oblong stud c³ is

page_text: fixed, the width of which, by, preference, corresponds with the width of the
spindle a. The stud centers a slot f! cut in the plate or disc f; the width of
the slot (except at one end) corresponds with the width of the spindle so as to
fit accurately thereon. A circular opening is formed at one end of the slot f¹,
and the platef is slid sideways on the stud c² until the spindle a is in a
central position with the circular opening at the end of the slot f', then the
plate or disc will revolve with the knob c in the act of screwing it up into
position upon the spindle, and when it is correctly adjusted thereon the plate f
is slid down into position concentric with the inner face of the knob, thereby
causing the square of the spindle a to enter the narrow part of the slot f'.
The plate f being connected to the knob c by the stud c³, and to the spindle a
by the slot f', then the knob c cannot be, moved to the right or to the left
without imparting corresponding movement to the spindle a, and from it
to the bolt of the lock. 9, 9, are metal plates free upon the spindle but
screwed to the sides of the door to which covering plates or roses h, h, are
screwed, as shown, the covering plate on the knob c serving to retain the
plate fin position; or a screw thread may be cut on the circumference of the
plate f, and have a covering ring screwed thereon, to retain the slotted plate or
disc fin position. The knobs b, c, and covering plates or roses h, h, shown in
this arrangement are made of earthenware, but this is not essential, as they
may be made of any other material or metal, such as ordinary door knobs or
handles are usually made of.
Figure 2 shows a longitudinal section of another pair of door knobs or
handles b, c, connected and secured to the spindle a according to my Invention,
the arrangement of the parts being similar to that previously described, except
the mode of connecting or locking the inside knob c to the plate f. In this
arrangement the plate or disc f is formed with a square hole f¹ to fit and slide
upon the spindle a, and there is a dovetail slot f' cut on its outer circum-
ference, which corresponds with a dovetail slot or groove c³ cut on the inner
face or plate forming part of the knob c, so that when it is screwed up and
adjusted in position on the spindle, and the two dovetail slots and f² are
brought opposite to each other, the double dovetail shaped key i is introduced
into the combined slots c and f, by which means the knob c and plate f will
be securely connected together, and any movement given to the knob c will be
transmitted through the platef to the spindle a. The key i is retained in
position by the covering plate or rose g, as in the arrangement previously
described.
I would remark that I do not confine myself to the exact arrangement and
construction of the parts herein shown and described, as they may be greatly

page_text: varied without departing from the nature of my Invention, which consists in
adjusting and securing knobs or handles in any desired position upon their
spindles, substantially in the manner herein shown and described.
In witness whereof, I, the said Isaac Parker, have hereunto set my
hand and seal; this Thirteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-three.
