IMPROVEMENTS IN ATTACHING KNOBS TO SPINDLES
Year: 1857

page_text: LETTERS PATENT to William Henry Collins, of Birmingham, in the
County of Warwick, Factor, for the Invention of "IMPROVEMENTS IN
ATTACHING KNOBS TO SPINDLES."
Sealed the 23rd September 1857, and dated the 25th March 1857.
PROVISIONAL SPECIFICATION left by the said William Henry Collins
at the Office of the Commissioners of Patents, with his Petition, on
the 25th March 1857.
I, WILLIAM HENRY COLLINS, of Birmingham, in the County of Warwick,
Factor, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN ATTACHING KNOBS TO SPINDLES," to be as follows:--
My said Invention consists of the improvements herein-after described in
attaching knobs to spindles. The object of my said improvements is to permit
of the ready and effective adjustment of the length of the spindle to the thick-
ness of the door to which the knob is to be attached. I make the spindle
square, and cut a screw thread on the angles of the spindle. The hole in the
knob is square, and the spindle fits therein; a small cylindrical screw box
works on the screwed spindle, and after the spindle has been passed through
the door, the said screw box is screwed to the requisite distance on the spindle.
The knob is placed upon the spindle and pushed thereon until the screw box
on the spindle enters a recess in the knob made to receive it; a small screw
is then passed through the shoulder of the knob, and taking into the screw.
box secures the knob in its place. I sometimes make the knob screw on the
spindle, and make a slide on the spindle take into the shoulder of the knob, so

page_text: as thereby to prevent its rotation. This modification resembles the last
essentially, but requires the fixed knob to be attached to the spindle after the
adjustable one. I sometimes connect the screw box in the first described modi-
fication with the knob, so that the turning of the screw box causes both the
said screw box and knob to move simultaneously on the spindle; when
adjusted, the motion of the screw box may be prevented by a small screw
made to engage therein or otherwise, or the slide in the second described
modification may be made to engage with the rose on the door, and the knob
to screw on the said slide; the spindle in this case is loose, the knob being
attached to the door. But this and other modifications in details I do not
think it necessary here to describe.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Henry Collins in the Great Seal Patent Office on
the 23rd September .1857..
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY COLLINS, of Birmingham, in the County of Warwick, Factor, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of March, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twentieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Henry Collins, Her special licence that I, the said
William Henry Collins, my executors, administrators, and assigns, or such
others as I, the said William Henry Collins, my executors, adininistrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN ATTACHING KNOBS TO SPINDLES," upon the
condition (amongst others) that I, the said William Henry Collins, my
executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.

page_text: NOW KNOW YE, that I, the said William Henry Collins, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:
My said Invention consists of the improvements in attaching knobs to
spindles, herein-after particularly described and illustrated in the accom-
panying Drawing. Figure 1 represents in vertical and longitudinal section a
door knob attached to its spindle, according to the method by which I prefer
carrying my Invention into effect. a is the spindle, which consists of a square
bar or rod; on the angles of the spindle a a screw thread is cut, as repre-
sented. The hole in the neck of the knob 6 is square, and the spindle a fits
therein, the said knob b being incapable of turning upon the said spindle a.
On the spindle a a small cylindrical screw box c works, and after the
screwed end of the spindle a has been passed through the door, the screw
box c is screwed to the requisite distance on the spindle a, that is to say,
until it comes in contact with the door, or the rose placed upon the spindle
against the door. The knob b is then placed upon the spindle a, and pushed
thereon until the screw box c on the spindle enters the cylindrical hole made
in the shoulder of the knob for its reception. A small screw is then passed
through the shoulder of the knob b, which said screw engages in the screw
box c, and thereby secures the knob b in its place, the several parts being
in the relative positions represented in Figure 1.
The screw box c is repre-
sented in front view separately at c¹.
I sometimes modify my Invention in the manner illustrated in vertical
longitudinal section in Figure 2.
The knob e screws on the spindle d, and a slide f, shown separately in
front view at f, is placed upon the spindle d, the said slide f being incapable
of turning upon the spindle. In adjusting the knob e upon its spindle the
knob g must be removed. The knob e is screwed to the proper distance on
the spindle d, and the slide f brought into the position represented in Figure 2.
The spindle is then passed through the door, and the knob g fixed thereon in
the usual manner.
I sometimes modify my Invention in the manner illustrated in vertical
longitudinal section in Figure 3, that is to say, the screw box h engages with
the knob by a screw on the exterior of the said screw box engaging in the
shoulder of the knob i; or the said knob i may be connected with the screw
box h by a screw, similar to that at 6', Figure 1, engaging in a groove or
neck in the screw box h, so that the turning of the said screw box may cause
both the screw box and knob to advance simultaneously on the spindle.

page_text: I sometimes modify my Invention in the manner represented in vertical
longitudinal section in Figure 4, that is to say, the slide k is passed through
the rose 1, the said rose 7 being fixed on the door. The knob m is attached
by a screw or otherwise to the slide k, as represented, and the spindle o
may be introduced to any desired distance in the slide k and knob m, the
knob m, rose l, and slide k being fixed to the door. The knob p and spindle
o may be prevented from being drawn out of the door by a rose affixed to
the door engaging with the knob p, or in any other convenient manner.
sometimes pass the slide k through the rose from the front, and secure it
to the said rose by turning over the end passed through by burnishing of
burring.
I
Having now described the nature of my said Invention, and the manner
of carrying the same into effect, I wish it to be understood that I do not limit
myself to the precise details herein described and represented, as the same
may be varied without departing from the nature of my Invention; but I
claim as my Invention the methods of attaching knobs to spindles, herein-
before described, and illustrated in the accompanying. Drawing.
In witness whereof, I, the said William Henry Collins, have hereunto
set my hand and seal, this Eighteenth day of September, in the year
of our Lord One thousand eight hundred and fifty-seven.
WILLIAM HENRY COLLINS. (L.S.)
