IMPROVEMENTS IN THE MODE AND MEANS OF SECURING LOCK AND DOOR HANDLES OR KNOBS TO THEIR SPINDLES
Year: 1884

page_text: I, ROBERT ROBERTSON PARKER, of Dalmuir, in the county of Dumbarton,
Ironmonger, do hereby declare the nature of my said Invention for "IMPROVEMENTS
IN THE MODE AND MEANS OF SECURING LOCK AND DOOR HANDLES OR KNOBS TO
THEIR SPINDLES," to be as follows:-
The improvements of this said invention are for securing the lock and door
handles or knobs to their spindles in a more simple, efficient and durable manner
than heretofore, which improvements will entirely prevent the vexatious incon-
venience of these handles continually getting loose as heretofore constructed.
And the nature and novelty of the invention consist in boring or forming a series
of small pin holes nearly close together right through the square or stem part of
the spindle which enters the inner socket part of the knob or handle; and further
in forming the inner socket part of the handle secured to the spindle parallel or
cylindrical for a short distance on the outside. A radial hole is bored or formed-
right through the centre of this cylindrical shoulder, and of the same size and in
the same radial line as the holes in the spindle, for the insertion of a metal pin
through them from the outside to secure the handle to its spindle. A new or
improved shield cap or ring disc with a short socket collar is fitted loosely on the
inner end of the handle, with the ring disc between this and the door, and with
the collar projecting out over the cylindrical shoulder of the handle and the hole
through it, for the purpose of retaining the pin in these, as will hereinafter be
explained. The pins are made of steel or good wrought iron, as they require to be
small (not to have large holes through the spindle to weaken it), and each pin is
made of a length equal to the diameter of the shoulder of the handle and hole
through it. For the insertion and removal of the pin, a hole is also formed
through the outer socket part of the shield cap, corresponding to that in the
shoulder of the handle, which it covers. The handle with its shield on it and the
holes in both of these in a line, is inserted over the square or projecting end of the
spindle until the inner face of the shield comes up against the door, when the pin
is then inserted through the nearest hole in the spindle coinciding with the holes
in the handle, to secure this in proper working position; then the shield which is
loose is turned a quarter round and secured, by two small screws to the door,

page_text: through ears or a flange on the outside; and as this combined washer and cap
answer for the practical use also of the usual ornamental rose washer, between the
handle and the door, this can be dispensed with, unless preferred for ornament.
This brings the holes in the outer socket or cap out of the working line of those
in the shoulder, so that the solid cap part covers in and locks the pin within the
handle and spindle, allowing these freedom to turn in either direction the full
distance the spindle is required and allowed to turn in opening or closing the door.
For brass or other metal handles and fittings (or "furnitures") an ornamental
flange could be formed round the outside of the disc part of the shield cap to
secure it to the door and make this answer for the ordinary ornamental rose
washer; but when these washers are required (as for wood, china, or other
ornamental handles) they can be made with large eyes to be slipped over the
shoulder of its handle before securing this to the door outside, either by the same
screws, or by additional screws or nails for itself or screwed internally to fit a
corresponding thread on the outer surface of the cap. With these improvements
the spindle can always be square and fit a deep square eye in the metal handles,
or the metal bush and rim, in wood and china handles, and which would not wear
or get loose or throw the strain on the pin which would only be required for its
proper purpose of keeping the handle on the spindle, and so be more secure and
durable than handles secured by screw spindles and lateral securing screws.
For
more accurate adjustment, two holes could be formed through the shoulder and its
cap at right angles to and in advance of each other, to the extent of half the
distance between the holes in the spindle, the pin being inserted into whichever
hole suited best for working without slackness; or to give the like adjustment, two
sets of holes could be formed through the spindle at right angles to and in the
centre of the spaces between the other set of holes; and when more accurate
fitting is desired, both of these arrangements might be adopted, which would give
an adjustment to one fourth of the distance or division between the one set of holes
in the spindle, and which, in that case, would be the distance the two holes in the
handle and its cap would be in advance of each other.

page_text: I ROBERT ROBERTSON PARKER of Dalmuir in the county of Dumbarton,
Ironmonger, do hereby declare the nature of my invention for "IMPROVEMENTS IN
THE MODE AND MEANS OF SECURING LOCK AND DOOR HANDLES OR KNOBS TO
THEIR SPINDLES," and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :—
The improvements of this said invention are for securing the lock and door
handles or knobs to their spindles in a more simple efficient and durable manner
than heretofore.
My invention is illustrated in the accompanying drawings in which figures 1
and 2 are longitudinal sections of a door handle, and figure 3 is a transverse
section.
In carrying out my invention I form a series of small pin holes a both hori-
zontally and vertically close together right through the. square or stem part of the
spindle A which enters the inner socket part of the knob or handle B and I form
the inner socket part b of the handle which is secured to the spindle parallel or
cylindrical for a short distance on the outside. Two radial holes are bored or
formed right through the centre of the cylindrical shoulder b at right angles to
each other but one of them about the thickness of itself in advance of the other
for finer adjustment these holes being of the same size and in the same radial lines
as the hole in the spindle into which I insert a metal pin c from the outside to
secure the handle B to its spindle A. A shield cap or ring disc C with a short
socket collar is fitted loosely on the inner end of the handle with the ring disc
between this and the door and a screwed ring or collar D is fitted over the
cylindrical shoulder of the handle for the purpose of retaining in place the pin
which locks together the handle and the spindle. The pins are made of steel
wrought iron or gun metal and each pin is made for a length equal to the diameter
of the shoulder of the handle. For the insertion and removal of the pin c the
screwed cap D in figure 1 is partially unscrewed and in the case of the loose cap D
in figure 2 a hole or holes is or are formed through the collar D corresponding to
the holes in the shoulder of the handle which it covers. The handle with its
shield on it is inserted over the square or projecting end of the spindle until the
inner face of the shield comes up against the door when the pin is then inserted
through the nearest hole in the spindle coinciding with the holes in the handle to
secure this in proper working position then the cap is screwed up or the collar D
is turned slightly round. This brings the holes in the outer collar or cap out of
the working line of those in the shoulder so that the solid cap covers in and locks
the pin within the handle and spindle allowing these freedom to turn in either
direction the full distance the spindle is required to turn in opening or closing the
door.
A single vertical or horizontal row of holes in the spindle may generally suffice,
but for more complete adjustment I employ both sets of holes and I form the holes
in the shoulder b and its cap D at right angles to and in advance of each other to

page_text: the extent of half the distance between the holes in the spindle A the pin c being
inserted into which ever hole suited best for working without slackness. The one
handle B only is loose and is secured as described the spindle being rivetted or
otherwise fixed to the other handle in the usual way.
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 mode herein described of securing a door handle to its spindle by means of
a pin passed transversely through the spindle and through a shoulder on the handle
said pin being retained by a ring or collar fitting over said shoulder and having
two holes in the shoulder at right angles the one in advance of the other to give
finer adjustment substantially as set forth.
