I THOMAS SANDERS of St. Mary Street Ladywood Birmingham in the County of
Warwick, Brassfounder, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to improve the method by which the ordinary door
knob is secured to the spindle of the lock or latch.
It is applicable to that kind of furniture in which the square spindle is secured
by means of a screw through the neck of the knob.
It may be used with a brass knob, or with a knob made of wood, bone, china,
or other suitable material as hereinafter described and illustrated by the accompanying
drawings.
The chief novelties of this invention are as follows:-
The screw instead of screwing directly on to the spindle, screws upon a plate of
metal which presses against and holds the spindle.
The screw instead of being placed in the neck of the knob from the outside is
placed through. from the inside.
Figs. 1. 2. 3 & 4 illustrate iny invention as applied to a brass knob.
Figs. 1. 2. & 3 illustrate the different stages of making the plate.

after which it is bent up, the screw inserted and then folded over as shewn. in fig. 3.

withdrawing the spindle.
The spindle is preferably notched or toothed as illustrated, in figs. 4 & 11.

the socket of the same.
The aforesaid lining is flanged and turned over at the end for the purpose of
protecting the knob as illustrated at fig. 11.

The method of adjustment is as follows:-
First the screw and socket are placed in the perforation in the neck of the knob
from the inside after which the flanged lining: is inserted then the spindle with the
teeth side in such a position that they will come into contact with. the projection
or tooth on the flange lining, when screwed, against it by, the, set screw..

Improvements in Furniture for Locks, Latches, and other like
Articles.
I, THOMAS SANDERS of St. Mary Street, Ladywood Birmingham in the County of
Warwick Brassfounder 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 object of this invention is to improve the method by which the ordinary door
knob is secured to the spindle of the lock or latch.
It is applicable to that kind of furniture in which the square spindle is secured
by means of a screw through the neck of the knob.
It may be used with a brass knob or with a knob made of wood bone, china, or
other suitable material as hereinafter described and illustrated by the accompanying
drawings.
The chief novelties of this invention are as follows.
The screw instead of screwing directly on to the spindle screws upon a plate of
metal, which presses against and holds the spindle.
The screw instead of being placed in the neck of the knob from the outside is
placed through from the inside.
Figs. 1. 2. 3 & 4 illustrate my invention as applied to a brass knob.
Figs. 1. 2. & 3 illustrate the different stages of making the plate.
Fig. 1. being a section and fig. 2 a plan of the flat blank perforated for the
screw; after which it is bent up, the screw inserted and then folded over as shewn
in fig. 3.
Previous to the turning up the plate is indented so as to form a suitable projection
to act as a tooth for gripping the spindle.
Fig. 4 shews the spindle placed in the knob and being held in position by means of
the plate, the said plate being operated upon by the screw.
It will be observed by reference to the drawings that the screw has a projection on
the underside so that it is impossible for it to be taken out except by first with-
drawing the spindle.
The spindle is preferably notched or toothed as illustrated in figs. 4, 11 & 15.
Figs. from 5 to 11 inclusive represent my invention as applied to a wood, bone,
china, or other knob, which is not suitable for tapping for a screw.
Fig. 5 represents a section and fig. 6 an elevation of an inside lining for the
knob having
a square hole suitable for the insertion of the spindle the sides of
which are slotted for the purpose of allowing them to yield when pressed against by
the screw and being filed flat and thin on the upper side for the purpose of
accommodating the screw and the socket of the same.
The aforesaid lining is flanged and turned over at the end for the purpose of
protecting the knob as illustrated at fig. 11.
Fig. 7 represents a section fig. 8 a plan and fig. 9 a side elevation of the screw
and socket before it is placed in its position in the neck of the knob as shown at
fig. 11.
Fig. 10 shews the knob prepared ready for the spindle and other fittings.
Figs. 12 13, 14, & 15 represent a modification in the inside lining upon which the
screw bears to receive the spindle, the said inside lining being preferably cut out by
press work as follows:
Fig. 12 shews the flat blank with the upper plate A which is afterwards notched
or toothed for gripping the spindle, the lower plate B which is afterwards
turned down for fitting in between the end of the knob and the circular disc as
shown at fig. 13 and the connecting arm C which holds the two plates together.
Fig. 14 shews the plate or lining finished ready for placing in position in the hole
in the knob.
This kind of plate may either be used with a metal or earthenware knob.

page_text: Fig. 15 shews a perforated metal disc lapped over on to the neck of the knob
at the edges for strengthening it, and fixed independently altogether of the inside
lining.
Fig. 15 shows the knob spindle, disc, inside lining, and socketed screw &c. fixed
complete in their proper relative position.
The method of adjustment is as follows:
First the screw and socket are placed in the perforation in the neck of the
knob from the inside after which the flanged lining or plate is inserted then the
spindle with the teeth side in such a position that they will come into contact with
the projection tooth or teeth on the flange lining or plate when screwed against it
by the set screw.
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 1
claim is :-
1. The screw inserted in the knob from the inside and having a projection so that
it cannot be taken out except by withdrawing the spindle as hereinbefore described
and illustrated in Figs. No. 1. 2. 3 & 4.
2. The said screw in combination with a notched or toothed plate upon which the
screw works for gripping the spindle as herein before described and illustrated in
Figs. 1. 2. 3. & 4.
3. The screw inserted in the knob, from the inside and having a projection so that
it cannot be taken out except by withdrawing the spindle in combination with a
notched or toothed plate upon which the screw works for gripping the spindle as
herein before described and illustrated in figs. 1. 2. 3 & 4.
4. The screw working in a loose socket in combination with a notched or toothed
inside lining or plate as and for the purpose specified and illustrated in figs. No. 5,
to 15 inclusive.
