RICHARD THOMAS GROCOTT, Earthenware Manufacturer, Whitehall Work,
Longport, Staff. do hereby declare the nature of this invention to be as follows:-
My invention has for its object improvements in apparatus for fastening knobs to
spindles.
The usual methods of attaching glass, earthenware and the like knobs, to their
spindles, is by means of a cast mount or fitting with short tube, or by stamped mount
or fitting with short tube of soft metal run on spindle.
It has been found in practice that the said short tube, adds considerable expense to
the manufacture of these mounts or fittings, and it is for improvements in this
direction, that this invention is chiefly intended.
For the purpose of my invention I use a mount consisting of a flanged disc
provided with an aperture through its centre to fit an ordinary spindle, said
mount I attach to knob by the ordinary method of burnishing down the edge of
flange.
To fasten the knob to its spindle I use a small screwed nut with a flange upon one
end, this screwed nut I place in the aperture in the knob, the round portion fitting
in the hole usually provided for the fastening screw to pass through. To prevent said
nut from falling out when the knob is not on the spindle, I expand the outer end of
nut with a centre punch. I then put a set screw into the nut in the usual manner to
fasten said knob to spindle.

page_text: RICHARD THOMAS GROCOTT, Earthenware Manufacturer, Whitehall Works,
Longport, Staff. do hereby declare the nature of my invention for IMPROVEMENTS
IN APPARATUS FOR FASTENING KNOBS TO SPINDLES, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:—
My invention has for its object improvements in apparatus for fastening knobs to
spindles.
The usual method of fastening glass, earthenware, and the like knobs to their
spindles, is by means of a cast mount or fitting with a short tube, or by stamped
mount or fitting with a short tube of soft metal run on the spindle.
It has been found in practice that the said short tubo adds considerable expense to
the manufacture of these mounts or fittings, and it is for Improvements in this
direction, that my invention is chiefly intended.
For the purpose of my invention, I use a mount or fitting consisting of a flanged
disc provided with an aporture through its centre to fit an ordinary lock spindle, said
mount or fitting I attach to knob by the usual method of burnishing down the edge
of flange. To fasten the knob I use a small screwed nut with a flange at one end, this
screwed nut I place in the aperture in the knob, the round portion fitting into the hole
usually provided for the fastening screw to pass through. I then secure the knob by
screwing in the fastening screw and tightening on to spindle.
The accompanying drawings illustrate the mode of carrying out my invention, the
same letters referring to the corresponding parts in each figure.
Fig. 1 shews in plan and fig. 2 in section, my invention for fastening door knobs
to spindles. Fig. 3 shews another mode of applying same, in which case the foot of
knob A and flange of mount or fitting 6 are made deeper, the said mount being also
provided with a tongue h formed out of its centre. Fig. 4 is a front view of figs. 12
and three.
In figs. 1 and 2 it will be seen that the mount or fitting is simply a flanged disc
provided with a square aperture in its centre to fit spindle d, and may be formed or
stamped out of sheet metal. g is the flanged nut, screwed internally, the round part
of which fits into aperture f, its flange preventing it from being forced through the
said aperture when the fastening screw is tightened on to spindle, and, being turned
up at one end, holds the nut in position when the spindle is withdrawn. In fig. 3,
instead of cutting the metal clear out of the mount or fitting, to form the aperture
for the spindle to pass through, as in figs. 1 and 2; I cut the metal on three sides
only as shewn in fig. 5, and bend it back to form a tongue h (fig. 6) which fits into
aperture in knob, the advantage of said tongue being to keep flanged nut 9 in position
when the spindle is withdrawn, and also provide a firmer method of attaching knob to
spindle, by forming a bearing for fastening screw c, close to spindle d.

page_text: This latter method is particularly applicable to wooden knobs and for which purpose
it may be used either with or without flanged nut g as desired.
The method of forming the holes through flange and tongue of mount is as
follows: Where flanged nuts are used, said nuts are first placed in position, and
the mount fixed to knob in the usual manner, as before mentioned; the knob is then
placed upon a suitable spindle with a hole in it opposite position of holes required in
flange and tongue of mount, the said holes are then drilled from the outside, the hole
in spindle being simply to allow drill to pass clear through tongue of mount. The
drilled holes are then tapped, fastening screw put in, and the knob is complete.
.
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: :-
1. The combination of the apparatus shewn in the annexed drawings, for fastening
glass, earthenware, and the like knobs to their spindles, and consisting of a plain mount
or fitting, and flanged nut.
2. In a mount or fitting, the tongue h, formed as herein described, for the
purpose of providing a firmer hold for fastening screw, by forming a bearing close to
spindle.
