PROVISIONAL SPECIFICATION.
Improvements in or connected with Apparatus for Attaching Door
Knobs to their Spindles.
I, BENJAMIN RICHARD GYPSON, of Lands Lane, Leeds, in the County of
York, Ironmonger, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to construct apparatus whereby door knobs may
be readily and securely fastened in position on their spindles, whilst at the same
time they may be easily removed should it be required to do so.
According to my invention, I cut or otherwise form a rack on the surface of the
spindle, the teeth forming the said rack being set towards the centre of the said
spindle. Within the handle I fulcrum a lever. having a projection or tooth at one
end of same, which latter is kept up to the rack by the weight of the opposite end
of the lever. A suitable aperture is formed in the handle for the purpose of
giving access to the lever when it is required to remove the handle from the
spindle. The above described arrangement of rack and lever catch, may be
applied to both ends of the spindle, thus making them interchangeable and suitable
for mortise or other kinds of locks. A dent or recess is formed in the back of the
lever, to enable a bradawl or other instrument to be pressed against same without
the liability of slipping.
In applying the lock furniture above described, the spindle is inserted in the lock
leaving a portion of its length projecting on either side of the door. The handles'
are then placed on the spindle ends, the projections on the levers passing along the
racks, until the handles rest against the side of the lock or door, when the levers
securely hold the handles in position. When it is required to remove the handles,
a bradawl or other instrument is inserted in the aperture in the handle and pressed
against the dent in the weighted end of the lever, thereby rocking the lever and
withdrawing the projecting end from the rack, thus releasing the handle and
allowing same to be removed.
By constructing two racks, one half a tooth in advance of the other, on
opposite sides of the spindle, a nicer adjustment may be obtained, as should a
handle fit loosely on the spindle, the required tightening may be effected by
turning the spindle round.

Improvements in or connected with Apparatus for Attaching Door
Knobs to their Spindles.
I, BENJAMIN RICHARD GYPSON, of Lands Lane, Leeds, in the County of
York, Ironmonger, 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 my invention, is to construct apparatus whereby door knobs may

page_text: be readily and securely fastened in position on their spindles, whilst at the same
time they may be easily removed should it be required to do so.
In order that my invention may be clearly understood, I will proceed so describe
same with reference to the accompanying drawing, in which the letters denote the
various parts.
A is the spindle and B is a handle which is fixed to one end of same. Care
rack teeth which are cut ou one side of the spindle, and D are rack teeth which
are cut on the opposite side of the said spindle, the teeth C and D being situated
so that one set is half a tooth in advance of the other. E is the adjustable handle,
and F is a weighted lever. fulcrume.l in same, and the outer end of the weighted
lever F is provided with a tooth G for engaging with the rack teeth C or D,
whilst the opposite end of the lever F is weighted at H. J is notch or recess
in the weighted eud H of the lever F, and K is an aperture formed in the
handle E.

In applying the lock furniture above described, the spindle A is inserted in the
lock leaving a portion of its length projecting. The handle E is then placed on
the spindle end, as seen in the drawing, thus causing the lever F to engage with
the rack teeth D, the weighted end H keeping the tooth G firmly up to its work.
When it is required to remove the handle E, a bradawl or other instrument is
inserted in the aperture K and pressed against the recess J, thereby turning the
lever Fon its fulcrum and releasing the tooth G from the rack D.
Should the handle E fit loosely on its spindle, the said handle is removed and
the spindle can then be withdrawu and turned over, and the situation of the teeth C
being different to that of the teeth D, the adjustment may be made with the
greatest nicety.
The above described arrangement of rack and lever catch, may be applied to
both ends of the spindle, thus making them interchangeable and suitable for
mortise and other kinds of locks.
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. An adjustable door handle carrying a weighted lever, in combination with a
spindle having a toothed rack on same, substantially as and for the purposes set
forth.
2. The spindle A having toothed racks C and D on same, in combination with
the handle E carrying a weighted lever F, substantially as and for the purposes
set forth.
3. The spindle: A, handle B, rack teeth C and D, adjustable handle E, weighted
lever F having a tooth G, weighted end H and notch or recess J in same, and the
aperture K, substantially as and for the purposes set forth.
