PROVISIONAL SPECIFICATION.
Improvements in the Method of Securing Latch Handles and Knobs
to Doors.
I, JOSEPH KAYE, of South Accommodation Road, Leeds in the County of York,
Lock Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to more effectually secure lock and latch handles
to doors in such a manner that the latch bolt may be easily operated, and a large
bearing surface obtained between the handle or knob and washer or plate by which it
is secured to the door, and to so arrange the connection between the handle or knob
and washer or plate that when the latter is attached to the door the handle or knob
cannot be removed.
I accomplish my object in the following manner- -The turning bar by which the
latch is operated is attached to the lock or latch and made to project beyond the face
of the door in the usual manner. The projecting portion of the bar is by preference
made square, an opening or recess of a corresponding section is made in the handle or
knob shank, the exterior of the shank is threaded for some portion of its length and
screwed into a plate or flange so that it can be easily turned therein.
On attaching the plate or flange to a door the end of the turning bar enters the
square hole or recess formed in the end of the handle or knob shank, the flange or
plate is then secured to the door by screws which leave the handle or knob free to
turn some portion of a revolution in the screwed or threaded part of the shank thus
operating the latch tongue and retaining a secure attachment to the door.

COMPLETE SPECIFICATION.
Improvements in the Method of Securing Latch Handles and Knobs
to Doors.
I, JOSEPH KAYE, of South Accommodation Road, Leeds, in the County of York,
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 more effectually secure lock and latch handles to
doors in such a manner that the latch bolt may be easily operated, and a large bearing
surface obtained between the handle or knob, and washer or plate by which it is
secured to the door; and to so arrange the connection between the handle and knob
and washer or plate, that when the latter is attached to the door, the handle or knob
cannot be removed without first detaching the washer or plate from the door.
In describing my invention in detail, reference is made to the accompanying
drawings, in which
Fig. 1 represents an elevation of a handle suitable for a railway carriage door, the
handle is shown engaged with a plate partly in section.
Fig. 2 represents a knob and washer arranged according to my invention, the
washer is shown in section, and
Fig. 3 an elevation of a different form of handle engaged with a plate which is
partly in section.
Similar letters indicate similar parts where they appear.
The turning bar A by which the latch is operated, may be square or of other

page_text: convenient section, and is attached to the latch tongue or to the lock in the ordinary
manner, and is of such length as to project beyond the face of the door.
The turning bar A is by preference made square, an opening or recess of corre-
sponding section is made in the handle or knob shank B in the direction of
its axis, and the exterior of the shank threaded at for some portion of its length and
screwed into a washer or plate C, so that the handle or knob can be easily turned
therein.
In the case of railway carriage doors handles shown by Fig. 1, the turning bar A may
be cast in or otherwise secured to the handle shank B at T, and of such length to extend
through and support the latch tongue, thus by mounting the handle in the screwed
socket of a washer or plate C in the manner described, there is no necessity for the
turning bar A to extend through the door, and to be secured by a nut or collar on the
inside of the door as is now the common practice; the threaded portion T when
the washer or plate is fixed to the door preventing the withdrawal of the handle from
the latch or door.
:
When the turning bar A is placed in the latch tongue, the respective handles or
knobs are screwed into the sockets of the washers or plates C, the latter are then
placed against the door, the turning bar A entering a hole of similar section formed
in the end of the handle or knob shank the washer or plate C is then attached to the
door by screws which leave the handle or knob free to turn some portion of a revolu-
tion in the screwed or threaded part T, thus operating the latch tongue in the direction
required for opening or closing the door, the knob or handle being free, but firmly
secured to the door by the threaded portion T and the screws passing through the
washer or plate C into the door, the threaded portion T having a large bearing surface
will afford ample provision for wear and tear.
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
The method of attaching handles and knobs to doors by combining the same with
washers or plates C all arranged substantially in the manner shown and described and
for the purpose as hereinbefore set forth.
