PROVISIONAL SPECIFICATION.
An Improved Handle for Mortise and other Locks and Latches.
We EDWARD CLIFFORD FEATHERSTONE of High Street Lindfield, Watch
Maker and HECTOR GERMAN of Ivy House Lindfield Surveyor both in the
County of Sussex do hereby declare the nature of the said invention to be as
follows:-
This invention has for its object an improved handle for mortise and other
locks and latches whereby a simple and inexpensive arrangement is provided so
that it will be impossible for the knobs to come off the spindles without being
deliberately unfastened.
In those now in general use it is well known that the small screw which secures
the knob to the spindle works out thus allowing the knob to come off, but by the
use of knobs or handles and spindles constructed according to our invention this
evil is entirely obviated.
Our invention consists in forming the handle or knob in two parts and joining
such parts together by means of bayonet or other joints as hereinafter described.
The socket where the spindle enters the handle is constructed as usual but the
screw hole is dispensed with, the spindle is threaded or perforated at the end
entering the socket part of the handle to receive a nut or for the reception of a
split pin or cottar or any other desired fastener for the purpose hereinafter
described. In some cases it may be desired to form the other handle and the
spindle in one piece.
In practice, according to our invention we pass the spindle fixed to the one
handle through the door and lock, the other handle being in two parts viz. :-the
socket part and the dome or outer part. The spindle is passed through the socket
part thereof and a washer or collar is passed thereover said washer resting on a
suitable seat in the socket part of the handle and is secured in position by a split
pin or cottar being passed through one of the perforations in said spindle.
by a nut when the spindle is provided with a screw thread. We prefer the nut
and screw in some cases as any slack or looseness of the handle on the spindle may
be taken up.
Or
The dome or outer part of the handle is then secured to the socket part thereof
by means of the bayonet joints before mentioned or if desired the two parts may
be screwed together, and such parts may be further secured together by a small
screw passing through such parts.
It will thus be seen that a handle for mortise and other locks and latches may
be constructed so that it is impossible for the knob to come off, at the same time
it is easily unfastened when it is desired to take such handle from the lock.

An Improved Handle for Mortise and other Locks and Latches.
We, EDWARD CLIFFORD FEATHERSTONE of High Street Lindfield Watch
Maker and HECTOR GERMAN of Ivy House Lindfield, Surveyor, both in the
County of Sussex, do hereby declare the nature of our said invention and in
what manner the same is to be performed to be particularly described and

page_text: ascertained in and by the following statement, reference being had to the
accompanying drawings and to the figures and letters marked thereon:-
This invention has for its object an improved handle for mortise and other locks
and latches whereby a simple and inexpensive arrangement is provided so that it
will be impossible for the knobs or handles to come off their spindles without being
deliberately unfastened. In those now in general use it is well known that the
small screw which usually secures the knob to the spindle works out thus allowing
the knob to come off, but by the use of knobs or handles and spindles constructed
according to our invention this evil is entirely obviated.
Our invention consists in forming the handle or knob in two parts and joining
such parts together by means of bayonet or other joints as hereinafter described.
The socket where the spindle enters the handle is constructed as usual but the
screw hole is dispensed with, the spindle is threaded or perforated at the end
entering the socket part of the handle to receive a nut or for the reception of a
split pin or cottar or other desired fastener for the purpose hereinafter described.
In some cases it may be desired to form the other handle and the spindle in one
piece.
In order that our invention may be properly understood and readily carried into
effect we have appended hereto a sheet of drawings in which
Figure 1. is a longitudinal section showing a handle constructed according to
our invention showing the handle secured to the spindle and
Figure 2. is a similar view showing a slight modification.
According to our invention we pass the spindle A fixed to the one handle (not
shown in the drawings) through the door and lock or latch, the other handle
being made in two parts, vis. :-the socket part marked B and the dome or outer
part C.
The spindle A is passed through the socket part B thereof and a washer or
collar b, is passed thereover said washer resting in the socket part B of the handle
and is there secured in position by the split pin d being passed through one of the
perforations e in the spindle A, or by a nut d' (as shown in Figure 2.) when the
spindle is provided with a screw thread e'. In some cases we prefer this method
as any slack or looseness of the handle may readily be taken up.
The dome or outer part C of the handle is secured to the socket part B by
means of the bayonet joint for if desired the two parts B and C may be screwed
together, and such parts may if desired be further secured by small screws g
passing through such parts.
It will thus be seen that a handle for mortise and other locks and latches may
be constructed so that is impossible for the knob to come off, at the same time it
is easily unfastened when it is desired to remove the lock for repairs or other
purposes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what, manner the same is to be performed we declare that what we
claim is
The peculiar construction and arrangement of handles for locks and latches and
means for securing the same to their spindles substantially as herein described and
shown in the accompanying drawings.
