I ARTHUR CHARLES HENDERSON of 46 Southampton Buildings Holborn in the
county of Middlesex, and of 31 Lincoln Place, Leinster Street Dublin, Patent Agent
do hereby declare the nature of the said invention for IMPROVEMENTS IN FIXING DOOR
KNOBS ON THEIR SPINDLES, a communication to me from abroad by André Gobron,
of the city of Paris in the Republic of France, Merchant to be as follows :—
.
The object of the invention is to regulate and fix the position of the handle on the
spindle (without the aid of screws) to accommodate the varying thickness of doors.
Fig. 1 of the accompanying drawings represents a door handle seen partly in section,
with the improvements forming the subject of my invention.
Fig. 2 is a plan of the rose. Fig. 3 is a threaded tube hereafter mentioned a plan
being shown in the same Figure.
Fig. 4 is a screw nut, and a plan thereof, also part of this invention.
The handles position on the spindle is regulated by aid of the nut 6 screwing on to
the screw cut spindle a, at one end of the handle a recess being made for its reception
on the inside of the rose, the spindle passing through the square aperture f. Fig. 2;
the end of the spindle screws into a tube h, passing through the centre of the
handle.
Having first regulated the position of the nut b, to suit the thickness of the door the
spindle a is then screwed into the tube h at the head of the handle, which latter is
thus firmly secured and held between the nut 6 and tube h.

page_text: I ARTHUR CHARLES HENDERSON of 46 Southampton Buildings Holborn in the
county of Middlesex, and of 31 Lincoln Place Leinster Street Dublin Patent Agent
do hereby declare the nature of the said invention for "IMPROVEMENTS IN FIXING DOOR
KNOBS ON THEIR SPINDLES " and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, a com- 5
munication to me from abroad by André Gobron of the city of Paris in the Republic
of France, Merchant:-
The object of this invention is to fix and regulate the position of the handle on the
spindle to suit the varying thickness of doors.
This is effected by aid of a nut screwing on to the screw cut spindle at one end of 1
the handle, whilst on the other end of the spindle screws a tube passed through the
centre of the handle at its outer end. Having first regulated the position of the nut
to suit the thickness of the door the tube is then screwed on the spindle at the head of
the handle, which latter is thus firmly secured and fixed between the nut and tubo.
Fig. 1 shows a door handle and spindle seen in longitudinal section with the improve- 1
ments forming the subject of this invention.
Fig. 2 is an end view in front of the movable handle.
3
Fig. represents the fixing tube of the movable handle.
a is the square, screw threaded spindle, this is fixed in the knob f, and is threaded
at the end where the knob is fixed and regulated as required. b, is the nut screwing
on the screw threaded part of the spindle a―The part c is fixed to the handle and has a
recess for the reception of the nut 6. The handle is cut through the centre with a
square hole e for the passage of the spindle a. fis the movable knob it is intended to
fix and regulate its position on the spindle. 9 is the tube screwed on the spindle.
The invention therefore consists.
1st. In the employment of a nut or stop piece b screw threaded inside for screwing
on the spindle and regulating its length in accordance with the thickness of the door
including the lock so that it checks the knob ƒ so as to imprison it between the nut b
and tube g.
"
2d. The use of the bulbous part-e on the handle having a recess for the reception i
of the nut 6 and having a square hole e which also passes through the handle.
So that having regulated the position as desired of the nut b on the spindle by
screwing it thereon, the tube y, is then inserted into the aperture at the head of the

page_text: handle and is there screwed onto the spindle, by which means the knob is held prisoner
between the nut and tube.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
The method of regulating the position of door knobs or handles on their spindles and
there fixing them by means of a screw threaded nut b, screwing on the spindle a, and by
aid of the tube g, screwing in like manner on the said spindle, an aperture being made
at the head of the knob for the reception of the tube, and a recess being made in
the bulbous part c of the said handle for the reception of the nut, the whole in the
manner by the means and for the purposes herein set forth.
