PROVISIONAL SPECIFICATION.
Improvements in Securing Knobs or Handles to Door Locks and
Latches and to Door Knob Roses.
I, ANDREW CASHIN, of the firm of Joseph Payton & Co., of Walsall Street,
Willenhall, Staffordshire, Lock Manufacturer, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to provide simple and efficient means of securing
knobs or handles to door locks and latches and to door knob roses.
In carrying out this invention instead of attaching one or both of the said knobs
or handles to the square spindle which passes through a corresponding hole in the
follow in the lock or latch case, as is usual, I secure one of the knobs or handles to
the follow itself preferably by screwing the knob into the spindle hole of the follow
or on to the boss of the same. The knob or handle has the usual square hole
corresponding with the said spindle. When the said square spindle is passed
through the hole in the follow and into the knob screwed to the follow, the knob
is perfectly secure as the screw threads take any pushing or pulling strain on the
knob and by the square spindle engaging with both the follow and with the knob,
the latter is effectually prevented from coming unscrewed from the follow.
The knob at the other end of the spindle is by preference secured to its rose, so
as to turn therein, by a flanged collar which is passed through the rose from the
inside and screwed into the foot of the knob thus holding the rose between the
flange and the foot of the knob. Both the collar and knob have a square hole for
the spindle which locks the knob and the collar together. When the collar and
the foot of the knob become loose through wear the callar can be tightened up by
first removing the knob from the spindle. The rose is secured to the door by screws
as usual.
Or the knob can be arranged in any other convenient manner so as to turn
loosely on and be secured to the rose which is fixed to the door by screws.
A knob and rose secured together by a screwed collar as above described
can for mortice locks be very conveniently used at both ends of the spindle.
My invention is similarly applicable to locks and latches which have spindles of
triangular or other form which will engage with the follow and with the knob as
above described.
Instead of attaching the knob and follow together by screwing the one into the
other as above described, the boss on one of them may have a lateral projection or
projections which engages or engage with a corresponding internal projection or
projections on the boss of the other of them, so as to take any push or pull on the
knob which is compelled to turn with the follow by the spindle passing through
and engaging with both as above described.

Improvements in Securing Knobs or Handles to Door Locks and
Latches and to Door Knob Roses.
I, ANDREW CASHIN, of the firm of Joseph Payton & Co., of Walsall Street,
Willenhall, Staffordshire, Lock Manufacturer, 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 provide simple and efficient means of securing
knobs or handles to door locks and latches and to door knob roses.
I will describe my invention by referring to the accompanying drawings on which
Fig. 1 illustrates in section two door knobs secured to a door lock and to a rose
respectively according to this invention; Fig. 2 shews one of the said door knobs
and Fig. 3 the follow of the door lock separately; Fig. 4 is a modified form of the
same; Fig. 5 shews separately the door knob which is attached to the rose and
Fig. 6 is the flanged fixing collar of the same and Fig. 7 shews how my invention
is used with a mortice lock or latch; the remaining figures illustrate a modification
of my invention as hereinafter described.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.
A is part of the door, B is the lock or latch case fixed thereto, C is the follow
of the lock or latch, D is the knob or handle spindle, El is the knob which is
secured to the lock or latch, and E2 is the knob which is secured to the rose F
so as to turn therein, the rose F being fixed as usual to the door A. by screws f.
In carrying out this invention instead of attaching one or both of the knobs or
handles to the square spindle D which passes through a corresponding square
hole in the follow C in the lock or latch case B, as is usual, I secure the knob E¹
to the follow C preferably by screwing the foot e¹ of this knob into the spindle
hole of the follow which at 2 is screwed to suit the foot e¹ of the knob E'; or the
boss 3 of the follow may be prolonged as shewn in Fig. 4 so as to project beyond
the lock case for the knob to screw on to. In this case the foot of the knob is
screw threaded internally at e" as shewn in Fig. 5 to suit the boss c³. Each of the
knobs E E2 has the usual square spindle hole e³.
When the square spindle D is passed through the hole in the follow C and into
the knob E screwed to the follow, the knob E¹ perfectly secure as the screw
threads take any pushing or pulling strain on the knob E and by the square
spindle D engaging with both the follow C and with the knob E', the latter is
effectually locked to the follow and prevented from coming unscrewed therefrom.
The knob E at the other end of the spindle is by preference secured to its
rose F, so as to turn therein, by the flanged collar G (shewn separately by Fig. 6)
which is passed through the rose F from the inside and screwed into the foot e² of
the knob thus holding the rose between the flange g' of the collar G and the foot
of the knob. The collar G has a square hole g² corresponding with the spindle D
and, as before stated, the knob has a similar square spindle hole e², so that when
the spindle is passed through the collar G and into the knob E2 the latter and the
collar G will thereby be effectually locked together.
When the collar g2 and the foot of the knob E2 become loose through wear
the collar can be tightened up by first removing the knob or collar from the
spindle.
Or, in combination with the knob E¹ or handle secured to the follow C as
above described, a knob secured loosely to its rose in any well known manne
may be used.
A knob E and rose F secured together by the screwed collar G as abov
described can, for mortice locks, be very conveniently used at both ends of the
spindle D as shewn by Fig. 7.

page_text: My invention is similarly applicable to locks and latches which have spindles of
triangular or other form in cross section which will engage with the follow and with
the knob as above described, the holes c², e³, and g³, being made to correspond with
shape of the spindle.
Instead of attaching together the knob and follow or the knob and flanged
collar by screwing the one into the other as above described, the boss of one
of them may have a lateral projection or projections which engages or engage
with a corresponding internal projection or projections on the boss of the other
of them, so as to take any push or pull on the knob which is compelled to turn
with the follow or with the flanged collar by the spindle passing through and
engaging with both as above described.
An illustration of this modification of my invention is shewn by Figs. 8 and 9
where the boss or foot of the knob has two lateral projections e, et, and the
follow has two internal projections ³ ³ corresponding with the spaces between
the projections et e, so that when the knob is inserted in the follow and turned a
quarter round, the projections ³, c³ and et e will engage together and when the
spindle D is inserted the knob and follow will be effectually secured together
as above described.
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 :-
:―
1. The method of securing a door knob or handle to the follow of a door lock
or latch by screwing the door knob or handle in to or on to the follow, or by a
lateral projection or projections on or in the follow engaging with a corresponding
projection or projections on or in the knob or handle, in combination with the
square or other shaped spindle locking the knob or handle and the follow together,
substantially as hereinbefore described and illustrated by the accompanying
drawings.
2. The method of securing a door knob or handle to its rose by means of a
flanged collar threaded through the rose from the inside and screwed into or on to
the foot of the knob or handle, or the knob or handle and the flanged collar being
otherwise formed so as to engage together as set forth, in combination with the
square or other shaped spindle locking the collar and knob or handle together,
substantially as hereinbefore described and illustrated by the accompanying
drawings.
