PROVISIONAL SPECIFICATION.
Improvements in Lock and Latch Furniture.
We JAMES SILVERWOOD of No. 8 Paxton Street in the Parish of Barrow in
Furness in the County of Lancaster Joiner and ALFRED MOULE of No. 62 John
Street in the Parish of Barrow in Furness as aforesaid Brass Finisher do hereby
declare the nature of this invention to be as follows:-
The spindle which passes through the door and latch is nearly square in section
with the corners rounded and having a screw thread formed thereon throughout the
whole or a sufficient portion of its length.
The end of the spindle which is permanantly fixed to the fast knob may be
secured in a variety of ways similar to other lock furniture, but the way which we
prefer to adopt, in permanantly fixing the fast knob to wood furniture is to have a
collar of brass or other suitable metal or metalic alloy bored & screwed upon the
spindle and secured to the spindle by a pin passing through the collar & spindle,
upon the outside of this collar is chased a coarse thread, the wood knob is then
bored and the collar screwed in tight and pinned through the face into the knob to
prevent its turning round.
For the loose knob we adopt a similar collar, which is screwed into the knob and
secured from turning round by being pinned on the face. The flanged part of this
collar is drilled with four holes at right angles to each other and at right angles to
the spindle, these holes are each tapped with a screw thread.
A round loose collar with a faucet end and having a square hole through the
centre is then slipped upon the spindle to the desired position, (this collar has four
holes drilled in same but not tapped, the holes being large enough to allow of a
screw passing through into the screwed holes in the knob collar, the holes in the
loose collar exactly corresponding with the holes in the knob collar.
When the knob is screwed up on the spindle until it enters the faucet end of the
loose collar an ordinary screw same as used for lock furniture is passed through
the hole in the loose collar into the screwed hole of the knob collar, the adjustment
being so perfect that a quarter turn of the knob in either direction will bring it
opposite the next hole in the loose collar.
The screw is kept in its position by the rose which is screwed to the door being
placed over the loose collar covering the head of the screw.
This invention is applicable to all kinds of lock furniture.

COMPLETE SPECIFICATION.
Improvements in Lock and Latch Furniture.
We JAMES SILVERWOOD of No. 8 Paxton Street in the Parish of Barrow in
Furness in the County of Lancaster Joiner and ALFRED MOULE of No. 62 John
Street in the Parish of Barrow in Furness aforesaid Brass Finisher do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The spindle which passes through the door and latch or lock is nearly square in
section with the corners rounded and having a screw thread formed thereon
throughout the whole or a sufficient portion of its length.
The end of the spindle which is permanantly fixed to the fast knob may be
017

page_text: secured in a variety of ways similar to other lock furniture, but the way which we
prefer to adopt in permanantly fixing the fast knob to the spindle in wood furniture
is to have a collar of brass or other suitable metal or metalic alloy bored and
tapped with a screw thread and screwed upon the spindle and secured to the spindle
by a pin passing through the collar & spindle, upon the outside of this collar is
chased or otherwise formed a coarse thread for screwing into the wood knob.
The wood knob is then bored, the collar screwed in tight and pinned through the
face into the wood knob.
For the loose knob we adopt a similar collar, which is screwed into the wood
knob and secured from turning round by being pinned on the face.
These collars may be secured to the wood knobs in a variety of other ways but
we have only described this method of fixing the knobs as we find it a very
satisfactory way of permanantly securing the collars to the wood knobs.
The flanged part of this collar fixed to the loose knob is drilled with (4) four
holes at right angles to each other and at right angles to the spindle. These holes
are each tapped with a screw thread.
A round loose collar of brass (or other suitable metal or metalic alloy) having a
faucet end which slips over the collar on the loose knob and having a square hole
through the centre (of the size of the spindle) is slipped upon the spindle to the
desired position.
This collar may have one or more holes drilled in same but not tapped, the hole
or holes being large enough to allow of a screw passing freely through into the
screwed holes in the fast collar.
When the knob is screwed upon the spindle until it enters the faucet end of the
loose collar, an ordinary screw (same as is used for common lock furniture) is put
through the hole in the loose collar and screwed into the hole in the knob collar,
the adjustment being so perfect that a quarter turn of the knob in either direction
will bring one of the screwed holes opposite the hole in the loose collar.
The screw is kept in position by the rose (which is secured to the door with
screws) being placed over the loose collar & thus covering the head of the screw.
This invention is applicable to all kinds of lock & latch furniture.
DESCRIPTION OF THE DRAWINGS.
Fig. 1. shews a section through the door and illustrates the method of fixing and
adjusting the knobs.
a. is the knob, which is fixed permanantly to the spindle. b is the metal collar
screwed into the knob (if of wood) or attached by the ordinary methods, if of
metal, china, earthenware, or glass, this collar is secured to the spindle by a pin
passing through it and the spindle. bb is the rose fixed to the door. C. the
spindle passing through the lock or latch into the loose knob. d is the loose
collar having
a faucet (or socketed) end into which the collar on the knob is
inserted. e is the metal collar screwed into the wood knob, or fixed by other means
to knobs of other materials, the metal collar e has four holes in flange of same
tapped for screws as described, two of which are shewn in section. F is the door
in section. is the rose shewn pushed back over the knob until the knob is
adjusted to its position. In fixing this furniture the screwed spindle is passed
through the door & latch, the loose collar d is then slipped over the spindle
to its proper position, the loose knob (having the rose slipped over it) is then
screwed upon the spindle until the fixed collar enters the socketed end of the
loose collar and is screwed up till a proper adjustment has been secured, a
screw is then passed through the hole in the loose collar into one of the holes in
the knob collar, the rose is then placed over same and screwed to the door.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1st. The use of a loose collar having a socketed or faucet end and a square

page_text: hole in same for slipping upon the spindle, in combination with a metal collar
fixed to the loose knob having a number of screwed holes in flange of same
drilled at right angles to the spindle, which collar when screwed up on the
spindle until it enters the socketed end of the loose collar, may be adjusted till
one of the screwed holes corresponds with the hole in the loose collar & is
secured by a screw passing through both & the screw kept in position by the rose
when fixed to the door.
