Improvements relating to the Fixing of Door Handles.
Year: 1897

page_text: I, CHARLES ALFRED CONDER of Clovelly, Elm Park Road, Finchley
London N. do hereby declare the nature of this invention to be as follows:-
One of the handles is made with a square or prismatic slot for reception of the
door lock shaft so that the handle may not turn thereon, and such handle has at its
inner end a shoulder which may be screw threaded externally. The lock shaft is
of prismatic section with its edges screw threaded, and on the same screws a rose
having projecting exteriorly screw threaded boss. This boss has means for
engagement with the handle or its shoulder, for instance pins or teeth to engage in
recesses therein and when the shoulder is screw threaded its thread is preferably
the same diameter as and runs in continuation of the screw thread on the boss of
the rosc.
An internally screw threaded collar or union is adapted to be screwel
in the boss to hold the handle thereto when adjusted. The other handle might be
similarly attached or it may be simply, fixed permanently to the lock shaft.
In adjusting the movable handle, the shaft is passed through the door and lock
in the usual way, the rose is screwed on as far as desired, the handle is pushed on
up to the rose, the pins being caused to engage in the recesses so that the rose
cannot afterwards turn with regard to the handle and consequently with regard
to the shaft, and the collar or union is screwed up retain the handle and rose firmly
together.

Improvements relating to the Fixing of Door Handles.
I, CHARLES ALFRED CONDER, of Clovelly, Elm Park Road, Finchley, N.,
Moulding 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 :-
+
This invention relates to means for adjusting and fixing door handles, that is to say
the handles of the spindles which operate the locks of doors and the like.
This invention is illustrated in the annexed drawing in which
Fig. 1 is a longitudinal.section showing a door (the lock and its mechanism being
omitted) with the spindle and handles, one of which is about to be placed in
position. Fig. 2 shows this handle after adjustment and fixing.
Fig. 3 is a rear view of the adjustable rose.
Fig. 4 is a section on line 4-4 Fig. 3.
One of the handles is made with a square or prismatic slot B for reception of
the door lock shaft C so that the handle may not turn thereon, and such handle

page_text: has at its inner end a shoulder a which may be screw threaded externally. The
lock shaft C is of prismatic section with its edges screw threaded, and on the same
screws a rose D having a projecting exteriorly screw threaded boss d. This boss
has means for engagement with the handle or its shoulder, for instance recesses d'
to engage in teeth or pins a' thereon and when the shoulder a is screw threaded its
thread is preferably the same diameter as and runs in continuation of the screw
thread on the boss d of the rose D. An internally screw threaded collar or union E
is adapted to be screwed on the boss to hold the handle thereto when adjusted. In
order to prevent the collar E when screwed up to the rose D from working loose,
there is fixed to the rose a small angular or other shaped pine attached to a small
steel or other spring f. This pin projecting through the front of the rose engages
with a corresponding slot or depression g the loose collar E preventing it when
screwed up to the rose from being unscrewed without first depressing the small
pine by means of the finger nail or any tool. The other handle might be
similarly attached or it may be simply fixed permanently to the lock shaft C.
In adjusting the movable handle A, the shaft C is passed through the door and
lock in the usual way, the rose D is screwed on as far as desired, the handle is
pushed on up to the rose D, the pins al being caused to engage in the recesses d'
so that the rose D cannot afterwards turn with regard to the handle A and conse-
quently with regard to the shaft C, and the collar or union E is screwed up to
retain the handle A and rose D firmly together.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed 1 declare that what I
claim is -
·
1. The improvements relating to the fixing of door handles consisting in the
combination of the internally threaded rose D, the edge threaded prismatic
shaft C, the handle A with prismatic recess and means for engagement of the
handle to the rose and a coupling for connecting the handle and rose for the
purpose set forth.
2. The construction of the parts for the fixing of door handles upon their shafts
permitting of their adjustment and retention in adjusted position substantially as
herein described.
