Improvements in and in connection with Knobs for Door or Lock
Furniture.
We, PEROY JOHN KNIGHT of 3 Berkeley Street Hull, in the county of York, of
her Majesty's Customs, and GEORGE HOYES of 45 Mytongate, Hull, in the county
aforesaid, Ship Chandler, 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:-
Our present invention relates to knobs and spindles therefor which are used in
connection with locks, latches, catches or any other ordinary kind of door or gate
fastenings, and the object thereof is to render the method of securing the knob to
the spindle more perfect whereby the hitherto frequent annoyance of knobs becoming
loose or slipping off the spindles is entirely obviated; to attain which we construct
and arrange our improved knob and spindle in the manner illustrated in the accom-
panying sheet of drawings in which
Fig. 1 is a sectional elevation of larger part of knob and fig. 2 front view of
same.
Fig. 3 is a sectional elevation of smaller part of knob and fig. 4 a front view of the
same.
Fig. 5 is an elevation of a portion of the form of spindle we employ to receive our
improved knob.
Fig. 6. is an elevation partly in section of our improved knobs fitted to a lock,
latch, catch or other door fastening; and fig. 7 is also a sectional elevation of our
improved knob showing how the said knob may be expeditiously removed from the
spindle when required.
Like letters of reference designate similar parts in each figure.
Our improved knob is composed of two parts A and B. The larger part A is
formed with a circular hole a' arranged with a suitable screw thread.
The smaller or circular part B is also formed with a screw thread to correspond with
the hole a' formed in part A so that it may be screwed therein.
The smallest part B of knob has securely attached to it either by means of rivets
as shown, or by solder, or by any other suitable means, a spring 62 on the outer sides
of which is also preferably arranged a bow shaped spring which is likewise secured
to the part B.
The spring is arranged with its ends 63 bent inward as shown, and where pre-
ferred a suitable ferrule or tube 65 may be either made in one with the part B or
attached thereto and securely fixed between the legs of the spring b².
The centre portion of the face of párt B of knob as either an oblong slot ² formed
therein as shown in figs. 2, 3 and 4, or it may be arranged in any other form in order
to apply any suitable instrument such for instance as a screw driver in order to screw
up or unscrew the part B to or from the part A as required.
The spindle C figs. 5, 6 and 7 is arranged with a suitable number of notches or
serrations on two of its sides and is preferably square in cross section to suit the
ordinary spindle hole a formed in the knob.
In fitting up our hereinbefore described improvements to a lock, latch, catch or
other ordinary door or other like fastening, the spindle C is first placed in required
position therein, then the part B figs. 2 and 3 is screwed into part A figs. 1 and 2 so
that the springs 62 and 64 come within the knob see fig. 6. The ordinary square
hole a of knob is then pressed with the knob onto the end of the spindle Cand
forced by the hand of the person fixing such lock or other like furniture in such a
manner that the bent in portions or ends 63 of the spring brest within two of the
notches or serrated parts of spindle C thus firmly retaining and holding the knob

page_text: in required position as shown in fig. 6. The end of spindle C enters the ferrule or
tube b by which means the knob is more firmly supported as will be well under-
stood.
It will however be obvious that where preferred the bow shaped spring & may be
dispensed with and the spring only used, and also when desired the ferrule b³ may
be dispensed with in order to cheapen the manufacture of the knob.
When it is required to remove the knob from the spindle C, it is only necessary to
insert into the slot or apply other means where the centre portion of the part B is
otherwise formed-in order to give the said part B a part or portion of a turn thereby
removing the bent in ends of the spring from the serrated parts or notches c¹ and
to throw said ends onto the smooth or flat part of the spindle as shown at fig. 7, when
the knob may be removed from the spindle with facility.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :
1. Constructing knobs used for lock or door furniture in two parts A and B in
combination with a spring & substantially as described and illustrated in the drawings
annexed.
2. Knobs used for the purpose specified and made in two parts A and B in com-
bination with springs and substantially as described and set forth in the accom-
panying sheet of drawings.
3. Knobs used for door or lock furniture constructed in two parts A and B the
part B being arranged with a ferrule 6 and spring &² substantially as described and
illustrated.
4. Knobs for the purpose specified and arranged in two parts A and B the part B
having secured thereto springs and 6 and also a ferrulo or tube all combined
substantially as described and illustrated.
5. In combination with the knobs constructed as herein before described the use of
a serrated spindle C substantially as set forth.
