PROVISIONAL SPECIFICATION.
An Improved Means of Securing Door Knobs to their Spindles.
I, ROBERT WALKER, of 14 Bowman Lane, Leeds, in the County of York,
Furniture Dealer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to securing door knobs to the spindles.
I first construct the knobs of brass, wood, china, or any other suitable material.
I then construct the neck of the knob of any kind of metal, with a conical
threaded end, and divided into two or four, parts with a square hole through the
centre thereof. Then I construct a collar with a conical hole threaded to suit the
neck of knob, which when screwed up nips the conical end of knob tightly on to
the spindle.
The knob can be secured to any part of the spindle by screwing the conical
collar on the conical end of neck of knob.
Dated this Fourteenth day of September 1895.

An Improved Means of Securing Door Knobs to their Spindles.
I, ROBERT WALKER, of 14 Bowman Lane, Leeds, in the County of York,
Furniture Dealer, 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 securing door knobs to their spindles.
And its object is to provide simple and very ready means whereby the knob
portion may be not only securely fixed to its neck, but the knob and neck may be.
also easily adjusted upon the spindle as well as securely fixed thereon.
In the drawings hereunto annexed:-
Fig. 1 is an elevation with one of the knobs in section with this invention
applied.
Fig. 2 a part sectional elevation with this invention applied.
Figs. 3 and 4 are elevations of a spindle.
Figs. 5 and 6 are respectively a sectional elevation and front elevation of a
metal neck for a wooden knob.
Figs. 7, 8, 9, and 10 are respectively a plan, sectional elevations, and an end
elevation of collar.
Figs. 11 and 12 a plan and elevation of fastening wedge.
Like parts in all the views are marked with the same letters of reference.
According to this invention the knobs A are made of brass, wood, china, or any
other suitable material. In the drawings at Fig. 1 I have represented the kuob A
as being made of wood, but at Fig. 2 as being made of metal, say brass.

page_text: B is the neck which is made of any suitable metal such as brass, and for wood
or the like knobs, it is armed at one end with any desired number of projecting
tapering pins C. In the drawings three of these pins are shown. In order to
securely fasten the knob A to its neck B, a corresponding number of holes are
bored or otherwise formed in the knob A at an angle to its axis; into these holes
the pins C are placed, and as the neck is driven up to the knob the pins will
assume the position shown in Fig. 1. But for brass and other metal kuobs the
neck B is provided with a projection (Fig. 2) on to which the knob is placed and
secured by any suitable means, such as for example by brazing, or by pressure.
The end of the neck B, the furthest from the knob A, is provided with a screw
threaded conical end b, and which end is also provided with a number of longi-
tudinal slits 3, say two or four for enabling this end of the neck to have a better
grip upon the spindle E. In practice the longitudinal slits are shorter in length
than the collar D.
The collar D is provided with a taper hole screw-threaded to suit the screw
thread on the end 62 of the neck B and to form a nut for tightening the end of
the neck on to the spindle E. The collar D may be provided with two or more
flats d*, for turning purposes, and with a projection d (see Figs. 1, 7, and 8) which
fits in the recess of the ". rose or washer F as shown at Fig. 1, but when the
projection dis dispensed with, (as at Figs. 2 and 9) then the projecting flange d' of
the collar D may, if so desired, be made the same diameter as and to fit into the
recess of the " rose or washer F.
"
وو
"
The " rose or washer F may be of any desired size, shape, (such as
circular or hexagonal) and thickness, and may or may not be provided with
the recess f
The spindle E upon which knobs constructed according to this invention are
secured, is made of a straight piece of square iron.
In practice I only provide one of the knobs with a neck B having a split
conical screw threaded end and collar D with a screw threaded conical hole to
form a nut, but if desired both knobs may be alike. When the conical end b¹ and
collar D are dispensed with, the knob A¹ is fixed by pins C to a metal neck B¹
which is shaped to correspond with the neck B, and is provided_with_a
projection B arranged to fit into the recess f of the "rose or washer F. The
knob A and its metal neck B' are fixed to the spindle E by means of a wedge G
being driven into the longitudinal slit e provided for its reception in one end of
spindle E. A washer H of tin or other metal may be provided in the neck B¹
against which the head of the wedge G and end of the spindle E impinge.
"
The knob can be secured to any part of the spindle by screwing the conical
collar on the conical end of neck of knob.
To fix the knob and its neck upon the spindle E, one of the complete knobs,
say A¹, is made fast upon the spindle E by any convenient means such as either
by the collar D being screwed upon the neck, or by the wedge G. The spindle is
then passed through the door, after which the complete knob A having the collar D
screwed upon its neck B is placed on and by means of the collar D is tightened
upon the spindle E so as to be driven up tightly against the collar F which is
against the door. By placing a screw or other key upon the flat portions d* and
giving the collar D another quarter or half revolution, to cause it to travel
further upon the split conical end b¹ of the neck towards the pins C, not only will
the complete knob be released so as to be capable of turning, but it will also be
more securely fixed to the spindle E.
The herein described complete knobs may be applied to existing spindles as well
as to new ones.
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. A door knob constructed and arranged substantially such as herein described

page_text: provided with a split conical threaded end on which is screwed a collar for
tightening and securing the door knob to its spindle, substantially as herein set
forth and illustrated.
2. The combination with a door knob of the split conical screw threaded end 6'
formed on the neck of the knob, and the collar D provided with a conical screw-
threaded hole so as to form a nut for said conical end whereby the door knob is
secured to its spindle substantially as herein set forth and illustrated.
Dated this Ninth day of April 1896.
