AN IMPROVED METHOD OF AFFIXING KNOBS, HANDLES, AND SIMILAR ARTICLES TO THEIR SPINDLES
Year: 1884

page_text: I THOMAS ATKINS of Drayton near Penkridge, in the County of Stafford,.
Farmer do hereby declare the nature of my Invention for AN IMPROVED METHOD
OF AFFIXING KNOBS, HANDLES, AND SIMILAR ARTICLES TO THEIR SPINDLES to be
as follows:-
In the neck of the knob is a hole of a square or eccentric shape, through which:
the spindle passes.
In the interior of the knob is a cylinder which may be rotated upon its axis, and
which is held in position by a flange, or collar, fitting into a recess, (figs 1. & 2.)
This said cylinder is hollow the greater portion of its length, and is tapped with
a female screw. The solid, or outer end passes through the face of the knob, and
there contains a slit, or some other device, to receive a screw-driver, or other tool, ;
by which to turn it. (fig 3.)
Upon the spindle,-the cross-section of which is of the same shape, and size, as
the hole in the neck of the knob,-is cut a screw-thread corresponding to the one
in the cylinder.
In affixing, the knob is placed upon the spindle, then by turning the cylinder,
the screw in its interior engages with the screw upon the spindle, and so draws the
knob into its required position, and firmly retains it.
A modification may be made by reducing the diameter of the cylinder, and
cutting upon it the male screw, then by boring, and tapping the spindle, for the
female screw. (6g 4.)
I propose to make but one knob removable, the other being permanently
affixed to the spindle.
By "knob "I would imply knob, handle, or any article to which this principle
may be applied.

Farmer, do hereby declare the nature of my invention for AN IMPROVED METHOD
OF AFFIXING KNOBS AND SIMILAR ARTICLES 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 :—
In the neck of the knob is a square or eccentric hole through which the spindle
passes. Immediately in front of this said hole, in the interior of the knob, is a
cylinder held in position by a flange or collar fitting in a recess in such a manner
as to allow the said cylinder to rotate upon its axis. This said cylinder is hollow
the greater portion of its length and is tapped with a screw-thread. The solid or
outer end passes through the face of the knob, and there contains a slit or some
other device to receive a screw-driver or similar tool.
.
Upon the spindle-the cross-section of which is of the same shape and size as
the hole in the neck of the knob is cut a screw-thread corresponding to the one
in the cylinder.
-
In affixing, the knob is placed upon the spindle, the cylinder is then rotated by
means of the slit in its outer end, which will cause the screw in its interior to
engage with the one upon the spindle, and by this means draw the knob into its
required position, and securely retain it there.
I propose to make but one knob removable, the other being permanently affixed
to the spindle.
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 adapting of a permanently affixed rotating screw as the means of
attachment, as hereinbefore substantially described.
Dated this 22nd day of October 1884.
