PROVISIONAL SPECIFICATION left by the said John Kaberry at the Office
of the Commissioners of Patents on the 20th May 1878.
JOHN KABERRY, of No. 14, Russell Grove, Vassall Road, Brixton, in the County
of Surrey, Clerk of Works. "AN IMPROVED METHOD OF SECURELY FIXING KNOBS,
HANDLES, OR OTHER LATCH FURNITURE ON DOORS, GATES, OR OTHER ARTICLES."
I use on each side of the door, gate, or other article an oblong or other similarly
shaped rose plate to which the knob or handle is attached at or near the centre of
the plate, such plates being made sufficiently long to stride the mortise or other lock
both above and below; and I secure the plates to the door, gate, or other article
by a bolt or bolts passing through the upper portion of both plates, and through
the door, gate, or other article above the lock, and by a bolt or bolts passing through
the lower portion of both plates, and through the door, gate, or other article below
the lock, all such bolts being thus clear of the lock. By this means the knob handles
or other latch furniture are attached on both sides of the door, gate, or other article
far more securely and firmly than is the case according to any of the usual modes
of fastening.
Each knob or handle is attached to the rose plate by means of a nut screwed on
the neck of the knob or handle at the back of the plate, allowing the knob or handle
to turn freely on the plate, and the latch is worked by means of an ordinary square
spindle, which may be inserted loose in the knobs or handles.
I do not claim as any part of my Invention the mode of attaching the knobs or
handles to the rose plates, or the mode of working the latch; but I claim as my
Invention the mode of fastening the knobs, handles, or other latch furniture on the
door, gate, or other articles in manner above stated.

page_text: If the knob, handle, or other latch furniture is required on one face only of the
door, gate, or other article the same arrangement of plates and bolts may be used,
omitting the knob, handle, or other latch furniture on the opposite face, or the plato
on the opposite face may be dispensed with, the bolts in this case being carried
through the door, gate, or other article, or secured by nuts screwed close to the 5
opposite face.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Kaberry in the Great Seal Patent Office on the 20th
November 1878.
JOHN KABERRY, of No. 14, Russell Grove, Vassall Road, Brixton, in the County
of Surrey, Clerk of Works. "AN IMPROVED METHOD OF SECURELY FIXING KNOBS,
HANDLES, OR OTHER LATCH FURNITURE ON DOORS, GATES, OR OTHER ARTICLES."
This Invention has for its object an improved method of securely fixing knobs,
handles, or other latch furniture on doors, gates, or other articles.
And in order that my said Invention may be better understood and readily
carried into effect, I will now, with the aid of the accompanying Drawings (whereon
similar letters of reference indicate corresponding parts) proceed more particularly
to describe and ascertain the same.
Figure 1 of such Drawings is a view in longitudinal section of my improved
method of fixing lock furniture, and shewing the ends of the bolts fastened with
nuts, as at f, or taking into a boss cast on the plate itsolf as at f¹.
Figures 2, 3, and 4 shew various views of the face plates hereafter referred to,
and Figure 5 is a view partly in sectional side (elevation, shewing one of such
plates with suitable bosses or recesses formed or cast therein for the reception of the
ends of the screw or other bolts hereafter described, instead of fastening the same
with nuts, as shewn at f, Figure 1; and Figure G shews a crank face plate or brace
applicable to rim locks; while Figure 7 is a sectional view shewing the horizontal
bolts taking into the lock itself.
I proceed as follows:-On either side of the door, gate, or other article I place a
suitable face plate a made of metal, or any other suitable material, and of any con-
venient shape and dimensions, but preferably of an oblong form, as shewn in
Figures 2 and 4 of the accompanying Drawings.
I so arrange such face plates that they embrace or stride the entire length of the
mortise or other lock or latch fastening, both on the inner and outer side of the
door, as shewn by the dotted lines from a to a in Figure 1; and I form a suitable
orifice or aperture at or near the centre of such face plates, as shewn at b, Figure 4,
so as to allow of my attaching the knobs or handles thereto in any convenient
manner, as illustrated at c, Figures 1, 2, 4, and 5 of the accompanying Drawings.
I secure such face plates on either side of the door, gate, or other article by
means of two or more horizontal screw or other suitable bolts d, d, which entering
through one of such plates passes through the entire thickness of the door, and also

page_text: if preferred through the upper and lower portions of the lock itself, as shown at e, e,
Figure 7, through suitable holes forined therein for that purpose, and thence into and
through the second face plate. Or, if preferred, such face plates may be made of a
sufficient length to permit of such horizontal bolts passing through them, and also
through the thickness of the door just above and below the mortise or other lock or
fastening, as shewn in Figure 1; and for ordinary purposes I prefer to adopt this
latter method.
In order to hold such face plates and bolts securely in position I secure the ends
of such horizontal screw or other bolts by suitable nuts f, Figure 1; or if preferred
suitable bosses or recesses f. f₁, Figures 1 and 5, may be formed or cast on the
inner or outer side of such face plates, so as to allow of the ends of such screw bolts
entering and taking securely therein.
I affix the knobs or handles to the face plates by means of a suitable nut or
washer screwed on or otherwise secured to the neck of each knob or handle at the
back of the plate, so as to allow the knob to turn freely on the plate, and to easily
work the latch in the lock by means of an ordinary square spindle, which may be
inserted loose in the knobs or handles.
If the knob, handle, or other latch furniture is only required on one face of the
door, gate, or other articlo, the same arrangement of plates and bolts (omitting the
knob, handle, or other latch furniture on the opposite side) may be used; or the
face plate on the opposite side may be dispensed with altogether, the bolts in this
case being either carried through the door, gate, or other article, or secured by
suitable screws or nuts close to the face of the door, gate, or other article.
In applying my Invention to rim locks I use a suitable metal crank face plato
brace, or strap, two forms whereof are shewn at Figures 6, wherein the recess g
formed of suitable shape and dimensions to receive the projecting lock. Such metal
crank face plate, braco, or strap has suitable holes formed on its upper and lower
arms to allow of the horizontal bars being inserted therein, which after passing
through the thickness of the door take into and are secured to an oblong or other
suitable face plate on the opposite side in the manner already described. Or, if
preferred, I employ a rose plate of a circular, triangular, or any other suitable shape
and dimensions, which, after removing the inner knob or handle, I place on the
projecting spindle in such a manner as to allow the same to work loose. Such rose
plate has suitable holes made therein to allow of the same being secured by suitable
screws or rivets or otherwise to the face of the rim lock, after which I replace the
knob on the spindle, and then fasten the same thereto in any suitable and con-
venient manner; I then affix an oblong or other suitable face plate on the opposite
side of the door in any convenient manner.
My Invention is, however, more particularly applicable to mortise locks, and in
particular it allows of such locks to be fitted to very thin doors without in any
way weakening them, which has hitherto been impracticable.
By my improved method the knobs, handles, or other latch furniture can be
attached on both sides of the door, gate, or other article, or on one side only,
far more securely and firmly than by any of the ordinary methods at present prac-
tised; and where mortise locks are used by the employment of face plates and
horizontal bolts, as above described, the same or increased strength is imparted to
the door, when the furniture is bolted on as it possessed previous to being mortised
for the reception of the lock, and hence the facility afforded by my improved method
for fitting mortise locks to very thin doors, as before mentioned.
It is also not only a far simpler but a much stronger and more durable method
than any hitherto in use, as by my improved principle all strain upon the lock is
avoided, the spindle being loose in both lock and knobs or handles, while the usual
method of fixing the knobs to the spindle with small and troublesome screws is
rendered unnecessary.
It is also particularly adapted for the doors of offices, and other public buildings,
where slamming and heavy strain cannot be avoided.

page_text: Another advantage of my Invention is, that the annoyance and inconvenience
now so frequently experienced from knobs continually coming off is thoroughly
obviated, at the same time that knobs cr handles of any kind can readily be
fixed on my improved principles, and another advantage is that they can be readily
removed and refixed for painting or other purposes without in any way injuring the
same.
Old, loose, and troublesome knobs on doors now in use can be replaced with
knobs fitted on: this strong and durable principle without the removal of anything
but the loose knob.
Having thus particularly described and ascertained the nature of my said In-
vention, and the manner of carrying the same into operation, I would havo it
understood that I do not claim as my Invention the mode of attaching the knobs
or handles to the face plates, or the mode of working the latch herein-before men-
tioned; but what I claim and desire to secure by the herein-before in part recited
Letters Patent is, the firmly attaching knobs, handles, or other latch furniture to
doors, gates, or other articles by means of oblong or other suitably shaped face
plates, so arranged as to stride the lock, and secured by two or more suitable
horizontal bolts, all substantially in the manner and for the purposes herein-before
set forth and illustrated.
In witness whereof, I, the said John Kaberry, have hereunto set my hand
and seal, this Twentieth day of November, in the year of our Lord One
thousand eight hundred and seventy-eight.
