WILLIAM NEILSON, of the Firm of Neilson and Livingstone, of Glasgow, in the
"IMPROVEMENTS IN
County of Lanark, North Britain, Wholesale Ironmongers.
DEVICES FOR ADJUSTING AND SECURING DOOR HANDLES."
This Invention has for its object to provide for adjusting and securing door
handles, devices which 'are simple and inexpensive in construction, convenient in
application, and not liable to get out of order.
In carrying out the Invention a square spindle is employed, and one end of it
The other end of the
is permanently fixed to one handle in the ordinary way.
spindle has ratchet-shaped grooves formed across one or more of its faces, and in
the neck of the corresponding handle there fitted a sliding catch piece, which
engages with the grooves in the spindle and prevents the handle from being drawn
off after being pushed on the spindle close up to the door. In one modification
the catch piece is in the shape of a small open frame, and is fitted to slide
The spindle
in V grooves formed partly across the inner face of the handle neck.
passes through the opening in the frame-like catch piece, and it is one inner edge
of the opening which engages with the ratchet grooves. A small blade, or spiral
or other suitable spring, is fitted so as to press the catch piece in the direction to
make it engage with the ratchet grooves of the spindle, and when it is necessary
to release the catch for the purpose of taking off the handle the catch piece is
pressed upon at the end opposite to the catching part by any convenient instrument,
which, when a rose or shield is used, is entered through a notch or small hole
therein. The catch piece may be modified by being shaped like the letter L, or
like two sides of the frame-like piece herein before described, one side being the
engaging part, whilst the other side serves for being acted upon by the disengaging
instrument.

WILLIAM NEILSON, of the Firm of Neilson and Livingstone, of Glasgow, in the
County of Lanark, North Britain, Wholesale Ironmongers. "IMPROVEMENTS IN
DEVICES FOR ADJUSTING AND SECURING DOOR HANDLES."
My said Invention has for its object to provide for adjusting and securing door
handles, devices which are simple and inexpensive in construction, convenient in
application, and not liable to get out of order.
In carrying out my Invention a square spindle is employed, and one end of it is
permanently fixed to one handle in the ordinary way. The other end of the
spindle has ratchet-shaped grooves formed across one or more of its faces, and in
the neck of the corresponding handle there is fitted a sliding catch piece, which
engages with one of the grooves in the spindle and prevents the handle from being
drawn off. A spring is applied to the catch piece, and provision is made for
moving the catch piece back when it is desired to take the handle off the spindle.
And in order that my said Invention and the manner of performing the same.
may be properly understood, I hereunto append a Sheet of explanatory Drawings,
to be hereinafter referred to, and representing my improved device.
Figure 1 on the accompanying Sheet of Drawings is a sectional side elevation of
a pair of door handles on their spindle, and Figure 2 is a side elevation showing
the parts as turned a quarter round from their position in Figure 1. Figure is
an inner elevation of the adjustable handle, and Figure 4 comprises an edge view
and face view of the catch piece as detached. In these Figures the same reference
numerals are used to mark the same or like parts wherever they are repeated.
One handle 5 is made a permanent fixture on the spindle 6 in the usual way, and
this spindle, which is of the ordinary square form, has ratchet grooves formed
across one or more of its faces near the end, on which the adjustable handle 7 is
to be placed. The catch piece 8 is in the shape of a small open frame, and is fitted
to slide in V-grooves formed partly across the inner face of the handle neck, or
across the face of the metal neck piece or mounting which is fixed to wooden and
some other handles, and is formed with a socket part 10 to receive the spindle 6.
The spindle 6 passes through the opening in the frame-like catch piece 8, and it is
one inner bevilled edge 11 of the opening which engages with one of the ratchet
grooves on the spindle 6. A small blade spring 12 is fixed to the side of the
socket piece 10, or a spiral or other suitable spring may be fitted in any convenient
way, so as to press the catch piece 8 in the direction to make it engage with the
ratchet groove or grooves of the spindle 6, and when it is necessary to release the
catch piece 8 for the purpose of taking off the handle 7 the catch piece is pressed
upon on the end 13 opposite to the catching part 11 by any convenient instrument,
-which, when a rose or shield 14 is used, is entered through a notch or small hole 15
therein. When the catch piece 8 has been entered into its V grooves in the neck
piece, it is prevented from becoming too far displaced by a small screw 16 screwed
into the neck piece through a narrow part of the opening in the catch piece.
Having thus particularly described my said Invention, and the manner of
performing the same, I have to state that I do not restrict myself to the precise
details herein described or delineated, and that I. do not claim forms of spring
catch acting in combination with ratchet grooves on the spindle, which have been
already used or proposed to be used, but which differ from what is herein described
or delineated, but that what I believe to be novel and original, and claim as the
Invention secured to me by and in terms of the hereinbefore in part recited Letters
Patent is,-
The constructing and combining together of the parts of devices for adjusting
and securing door handles in the improved manner hereinbefore described and

page_text: shown in the accompanying Drawings, the catch piece being in the form of a
small open frame fitted to slide in V-grooves in the neck or neck piece of the
handle.
In witness whereof, I, the said William Neilson, have hereunto set my
hand and seal, this Thirtieth day of January, in the year of our Lord
One thousand eight hundred and eighty two.
Witness,
EDMUND HUNT,
Patent Agent;
