Year: 1875

page_text: LETTERS PATENT to William Harrison, of Sheffield, in the County of
York, for the Invention of "IMPROVEMENTS IN SPINDLES AND ADJUSTABLE
APPLIANCES FOR FIXING DOOR HANDLES THERETO, ALSO ESCUTCHEONS FOR
DOORS."
Sealed the 21st September 1875, and dated the 22nd March 1875.
PROVISIONAL SPECIFICATION left by the said William Harrison at
the Office of the Commissioners of Patents, with his Petition, on
the 22nd March 1875.
I, WILLIAM HARRISON, of Sheffield, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
SPINDLES AND ADJUSTABLE APPLIANCES FOR FIXING DOOR HANDLES THERETO, ALSO
ESCUTCHEONS FOR DOORS," to be as follows:-

spindle. The said grooved channels are intended each to receive the
end of the screw commonly employed for fixing a knob or handle on to
a door spindle.
Another improvement in spindles consists in making a projecting boss.
on each half of the aforesaid divided spindle near that end thereof
opposite to the grooved part aforesaid. These bosses are intended to
take into a hole made in the neck of each door knob to receive the screw
for fixing the knob on to the spindle, and for this purpose the aforesaid
bosses are tapped to receive their respective screws. The split spindle
thus constructed is fixed each half into a knob or handle by a screw, as
before stated, and each half passed from opposite sides through the lock
of the door to which it is required to be affixed, the end of each part
of the spindle being pushed into the square hole in the knob until tho
handles come close to each side of the door, in which position they are
securely fixed and held by the screws in the bosses aforesaid, the points
of each of the said screws taking respectively into the aforesaid wedge-
shaped grooves in tho spindles, as before described. Thus it will be seen
that the effect of pulling the knob will be to tighten the screw in the
wedge-shaped groove, and should one of the screws be taken out the
handle is still secured to the spindle by reason of the boss entering the
hole in the neck of the knob, as before stated.
The second part of this Invention relates to attaching knobs or
handles to solid spindles (which may also have a wedge-shaped groovo
in one or more sides thereof), and consists in connecting the spindle to
the knob by a bar which passes crosswise through the neck of the knob
or handle. The said bar has a hole made across it to receive the spindle,
and there is a screw tapped into one or both ends of the said bar, so that
when the said bar is placed in the knob and held while the spindle is
passed through it by screwing the screw it will be firmly connected
thereto. I propose to place a washer of wood or other material into a
suitable recess made in the base of the knob or handle, which when
applied to porcelain handles prevents liability to breakage, and for knobs
for cupboards and latches prevents rubbing against the door when the
knob is turned round.
The third part of this Invention relates to escutcheons for doors, and
consists in affixing or connecting them to the keyhole plate by a rivet
passed horizontally through a hole made in the plate and escutcheon,

page_text: the said rivet having a hole made near the end thereof for a pin to pass
through from the top of the escutcheon, thus securely fixing the
escutcheon to the keyhole plate.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Harrison in the Great Seal Patent Office
on, the 22nd September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HARRISON, of Sheffield, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of March, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
cighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Harrison, Her special licence
that I, the said William Harrison, my executors, administrators, and
assigns, or such others as I, the said William Harrison, 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
SPINDLES AND ADJUSTABLE APPLIANCES FOR FIXING DOOR HANDLES THERETO, ALSO
ESCUTCHEONS FOR DOORS," upon the condition (amongst others) that I, the
said William Harrison, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said In-
vention, 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 William Harrison, do hereby
declare the nature of my said Invention, and in what manner the

page_text: The first part of this Invention relates to what are known in the trade
as split spindles, and the improvement consists,-
First. In forming an inclined or wedge-shaped groove in one side of
each of the two halves of the spindle for about half the entire length
thereof, the inclined groove sloping upwards towards the end of the
spindle. The said grooved channels are intended each to receive the
end of the screw commonly employed for fixing a knob or handle on to
a door spindle.
Another improvement in spindles consists in making a projecting boss
on cach half of the aforesaid divided spindle near that end thereof
opposite to the grooved part aforesaid. These bosses are intended to
take into a hole made in the neck of each door knob to receive the screw
for fixing the knob on to the spindle, and for this purpose the aforesaid
bosses are tapped to receive their respective screws. The split spindle
thus constructed is fixed each half into a knob or handle by a screw, as
before stated, and each half passed from opposite sides through the lock
of the door to which it is required to be affixed, the end of each part
of the spindle being pushed into the square hole in the knob until the
handles come close to each side of the door, in which position they are
securely fixed and held by the screws in the bosses aforesaid, the points
of each of the said screws taking respectively into the aforesaid wedge-
shaped grooves in the spindles, as before described. Thus it will be seen
that the effect of pulling the knob will be to tighten the screw in the
wedge-shaped groove, and should one of the screws be taken out the
handle is still secured to the spindle by reason of the boss entering the
hole in the neck of the knob, as before stated.
The second part of this Invention relates to attaching knobs or
handles to solid spindles (which may also have a wedge-shaped groove
in one or more sides thereof), and consists in connecting the spindle to
the knob by a bar which passes crosswise in or through the neck of the
knob or handle. The said bar has a hole made across it to receive the
spindle, and there is a screw tapped into one or both ends of the said bar,
so that when the said bar is placed in the knob and held while the spindle
is passed through it, by screwing the screw it will be firmly connected
thereto. I propose to place a washer of wood or other material into a
suitable recess made in the base of the knob or handle, which when
applied to porcelain handles prevents liability to breakage, and for knobs
