RICHARD THOMAS GROCOTT, Earthenware Manufacturer, Whitehall Works, Long-
port, Staff. do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved method of attaching, glass, earthenware and
the like knobs to their spindles, by means of a spring and serrated spindle.
For the purpose of my invention I use a plain mount consisting of a flanged disc
fitting on the spindle and provided with a slot hole at the bottom. In said slot hole I
place one end of a spring so formed as to lie between the mount and knob for a short
distance and then turn in an angular direction to meet and fall in the transverse
grooves formed in the spindle, the aperture in the knob being made to suit same. In
order that I may release the knob from spindle when required 1 form a small hole in
the knob to allow a thin wire to pass. down and press the spring away from the
spindle, when the knob may be removed.

RICHARD THOMAS GROCOTT, Earthenware Manufacturer, White Hall Works, Long-
port, Staff. do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
-
My invention relates to an improved method of attaching glass, earthenware, and
the like knobs to their spindles, by means of a spring and serrated spindle.

page_text: For the purpose of my invention, I use a plain mount, consisting of a flanged disc
fitting on the spindle, and provided with a slot hole at the bottom. In said slot hole
I place one end of a spring so formed, as to lie between the mount and knob for a
short distance, and then turn in an angular direction to meet, and fall in the transverse
grooves formed in the spindle, the aperture in the knob being made to suit same.
In order that I may release the knob from spindle when required, I form a suitable
hole in the knob to allow a thin wire to pass down and press the spring away from the
spindle when the knob may be removed.
The mode of carrying out my invention will be clearly seen by referring to
accompanying drawings, in which the same letters refer to the corresponding parts in
cach figure.
In figure 1. A represents a part sectional elevation of a knob shewing the arrange-
ment of spindle and spring. The mount B as will be seen, consists simply of a
flanged disc provided with an aperture to slide on the spindle C and attached to the
knob by the usual method of burnishing the edge of the flange down to meet curved
part of knob. Said mount is also provided with a shallow recess and slot hole to
receive one end of spring D and keep it in its proper place. The other end of
spring D turns in an angular direction as shewn, to meet the spindle and catch in the
transverse grooves E formed in spindle C.
I may here mention that it is not imperative to provide a slot hole in the mount to
receive one end of spring, as it has been found that the recess will answer the
purpose alone.
All that is required to be done to attach a knob to its spindle by my invention is to
press the spindle down the aperture in the knob to the required distance when the
spring will catch in the grooves and prevent it from being withdrawn.
When it is required to remove the knob from its spindle, I insert a thin wire down
the aperture formed in the knob, as shown by dotted line F, and press the spring away
from the spindle when the knob may be easily removed.
I would also have it understood that I do not confine myself to the exact details
herein before mentioned as the same admit of modification without departing from the
essential features of my invention.
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 of fastening glass, earthenware, and knobs of similar material to their
spindles, as herein described and illustrated by accompanying drawings.

In order that I may release the knob from spindle when required, I form a suitable
hole in the knob to allow a thin wire to pass down and press the spring away from the
spindle-when the knob may be removed.
The mode of carrying out my invention will be clearly seen by referring to
accompanying drawings, in which the same letters refer to the corresponding parts in
each figure.
In figure I. A represents a part sectional elevation of a knob shewing the arrange-
ment of spindle and spring. The mount B as will be seen, consists simply of a
flanged disc provided with an aperture to slide on the spindle C and attached to the
knob by the usual method of burnishing the edge of the flange down to meet curved

spring D turns in an angular direction as shewn, to meet the spindle and catch in the
transverse grooves E formed in spindle C.
I may here mention that it is not imperative to provide a slot hole in the mount to
receive one end of spring, as it has been found that the recess will answer the
purpose alone.
All that is required to be done to attach a knob to its spindle by my invention is to

the aperture formed in the knob, as shewn by dotted line F, and press the spring away
from the spindle when the knob may be easily removed.
I would also have it understood that I do not confine myself to the exact details
hereinbefore mentioned as the same admit of modification without departing from the
essential features of my invention.

page_text: I am aware that such knobs have already been attached to spindles by means of a
spring acting upon and in conjunction with serrated teeth upon such spindles, and
further, have been released by means of a wire or other tool after this manner, and
therefore I do not wish to claim broadly the method of securing knobs to spindles by such
spring and serrations upon the spindle but ;
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 claim is:
The mode of fastening glass, earthenware, and knobs of similar material to their
spindles, as herein described and illustrated by accompanying drawings.
