Year: 1852

page_text: Sealed the 2nd March 1853, and dated the 4th October 1852.
PROVISIONAL SPECIFICATION left by the said Henry Webb and
Joseph Froysell at the Office of the Commissioners of Patents,
with their Petition, on the 4th October 1852.
We, HENRY WEBB, of Willenhall, in the County of Stafford, Engineer,
and JOSEPH FROYSELL, of the same place, Surgeon, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN FASTENING KNOBS TO
DOOR AND OTHER LOCKS" to be as follows:-
The improvements consist in adapting the well-known bayonet joint
to securing knobs to the spindle of door and other locks and latches.
The knob has cast or carries on its neck one or more projections
which take into a corresponding slot or slots made in a shield, rose, or
escutcheon affixed to the door or to the lock itself. Or we make a
corresponding slot or slots, as the case may be, in the "follow" of the
lock, into which the neck of the knob, with its projection or projections,
works.

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 FASTENING KNOBS
TO DOOR AND OTHER Locks," upon the condition (amongst others) that we,
the said Henry Webb and Joseph Froysell, by an instrument in writing
under our 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. '
NOW KNOW. YE, that we, the said Henry Webb and Joseph
Froysell, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, that is to say:
The nature of our said Invention having been described in our
Provisional Specification, it will only be necessary to repeat the same
here, and then by reference to the Drawings annexed we will 'proceed
to describe the manner in which our improvements are to be carried
into effect.

"The improvements consist in adapting the well-known bayonet joint
to securing knobs to the spindle of door and other locks and latches.
The knob has cast or carries on its neck one or more projections which
take into a corresponding slot or slots made in a shield, rose, or
escutcheon affixed to the door or to the lock itself. Or we make a
corresponding slot or slots, as the case may be, in the "follow" of the
lock, into which the neck of the knob, with its projection or projections,
works."
The manner in which our improvements may be carried into effect
is clearly shewn in the Drawings, which represent different views of
two locks having the knobs attached according to our Invention, and
of some of the parts detached.
Figure 1, is a horizontal section of a case lock attached to a door,
and with the knobs connected to the spindle of the lock according to
our improvements. Figure 2, is a side view of the lock with the knob
removed, and shewing a shield, by means of which that knob is attached.
Figures 3, and 4, are side and front elevations of the knobs. Figures
5, 6, and 7, are respectively a back and front view and section of the
shield, by which the second knob is secured; and Figures 8, 9,
and 10, are similar views of the rose or escutcheon for the knob.
Figure 11, represents the pin by which the escutcheon is held in place.
A, A, Figure 1, is the case of the lock, the working parts of which
are not shewn, as they form no part of our Invention, and may be of
any approved construction. B, is the wood work of the door or other
article to which the lock is attached; C, C, are the knobs or handles;
D; the knob spindle; E, the shield by which the first knob is secured
to the lock; and F, the shield which seryes to secure the second knob
to the door; an escutcheon being applied to give the knob when fixed
a more finished appearance. The knobs or handles C, C, are formed
with projections c, c, on their necks, which take into grooves formed in
the shields E, and F, and by which the knobs are secured to the lock on
either side. The method of connecting the knobs to the lock is as follows:
A knob.C, is first attached on one side of the lock by introducing its
projections through the slots d, d, Figure 2, so as to take into the

page_text: groove formed in the interior of the shield E; the knob is then turned
through a portion of a circle until the projections on its neck assume in
the groove the position indicated by the dotted lines in Figure 2, after
which the square or other spindle D, is inserted through the lock, by
which means the first knob is held firmly in its proper position on the
lock. The second knob, carrying with it its escutcheon, is then similarly
attached to the opposite side of the door to that on which the lock is
to be fixed, by means of its projections taking into the groove in the
interior of the shield F, which has been previously screwed to the door
in a recess cut for its reception. The two knobs being thus secured by
their respective shields, the one on the lock and the other on the door,
it now only remains to bring the lock with its projecting spindle to its
place in the door (taking care to carry the spindle into the knob on the
door side), and to screw it up, whereby the knobs will remain firmly
attached so long as the lock continues fixed to the door. When either
or both of the handles or knobs is or are required to be detached, the
lock must be taken off, which will permit them to be readily removed.
The second knob, or that which is attached to the door, should have a
rose or escutcheon applied in order to cover the shield F, which is sunk
in the wood work of the door, and produce a more finished effect than if
the shield were left exposed to view. When the lock is attached to the
door as in mortice locks previous to the handles or knobs being fixed
the shield F, cannot be screwed into place until after the first knob and
spindle have been applied. Then, as the second knob is secured by the
operation of screwing on the shield F, it will be necessary to employ
an escutcheon such as is shewn in Figures 8, 9, and 10; and in order
to allow of access to the screws the escutcheon is thrown back upon
the knob until after the operation of screwing the shield with its knob
to the door has been performed. The escutcheon is then carried for-
ward to the door, and fixed by means of the pin, Figure 11, previously
driven into the wood work, or otherwise fixed by passing the head of
the pin into the groove in the escutcheon, and turning the escutcheon
partly round (the head of the pin being in the groove), until it assumes
the position shewn in Figure 8, where it is represented as having
dropped slightly lower than its first position, and as being suspended on
the pin so as not to interfere with or be affected by the turning of

page_text: the knob or handle. Figure 12, is a horizontal section exhibiting
our method of securing the knobs or handles as applied to the "follow
of mortice and other locks; and Figures 13, 14, 15, and 16, are
different views of some of the parts detached. A, is the lock; B, B,
the wood work of the door in which it is fixed; C, C, the knobs
or handles; D, the knob spindle; E, the "follow" of the lock; and
F, the shield by which the second knob is attached. In this case the
"follow" of the lock has a groove formed on its interior, as shewn in
Figures 13, and 14, into which the projections on the neck of one of
the knobs take, and by means of which that knob is held in its place.
The second knob, with its rose or escutcheon, is secured to the lock by
means of the shield F, shewn separately in Figures 15, and 16, in the
same manner as before described with reference to the case lock.
same mode of securing the knobs or handles by means of the groove
in the "follow" of the lock may also be applied to case locks. We
have not thought it necessary to shew a Drawing of a casc lock with
the handles secured in this way, as the method of applying them will
be readily perceived by any practical mechanic by reference to the
Drawings. It will also be readily seen that our improved mode of
securing handles or knobs is applicable to those composed of wood,
glass, porcelain, &c., and in this case the projections on the necks of
the knobs would be formed on the metal lining which is always applied
to handles composed of such materials.
The
And having now described the nature of our said Invention, and the
manner in which the same is to be performed, we declare that,
What we claim is, the fastening of knobs or handles to door and
other locks in the manner herein-before exemplified and described.
In witness whereof, we, the said Henry Webb and Joseph Froysell,
have hereunto set our hands and seals, this Twenty-eighth day
of March, One thousand eight hundred and fifty-three.
