I, ORVELLAS HENRY GILBERT of Lombardy Street in the City of Newark, County
of Essex and State of New Jersey United States of America Manufacturer do hereby
declare the nature of this invention to be as follows:-
This Invention relates to improvements in latch drawing mechanism and door
furniture generally, but has reference more particularly to improvements in a previous
invention for a similar purpose for which an application for Letters Patent of the
United States was filed November 6, 1884, No. 147,252.
The primary object of the present invention is to provide a latch-actuating device
which can be secured to the door above the lock mortise and to permit the use of a
knob to operate the said latch-actuating device, so that in whatever direction the knob
is turned it will draw the latch.
The furniture is also made reversible for either right or left hand doors, or opposite
sides of the same door.
The invention consists of a lever pivotted to a rose plate out of centre with the axis
of revolution of the knob &c., preferably above the same and operated by suitable
means.
According to the said invention the rose and the escutcheon may be cast in one
piece or separately.
When the rose is cast independently of the escutcheon, or when the rose and
escutcheon are formed integrally, lugs or ears are formed on each side of the rose in
a line with the shank perforation, through which the screws pass that hold the rose to
the door.
The latch-actuating lever consists essentially of a main portion and a finger or bent
end which projects into the lock case and engages with the latch.
The said main portion is preferably formed with an opening therein to allow
sufficient room for the nut on the end of the bolt which holds the parts together, and
permits the pivoted lever to swing when operated by the handle &c.
The said lever is preferably pivoted above the shank perforation or above the centre
of the axis of revolution of the knob, and near the top of the rose, or as far up as is

page_text: desirable, to secure the requisite leverage, and extends down within the rose below
the shank perforation and swings freely therein.
To operate the pivoted lever and cause it to draw the latch I employ a device which
is so constructed and arranged in relation to the knob &c., as to draw the latch whether
the knob is turned to the right or to the left and which also may be reversed so that
the same furniture may be used on either right or left hand doors.
To accomplish this a plate is secured to and turns with the shank or bolt passing
therethrough, and extending out beyond the outside of the lever is provided with
posts or projections which engage with the lever when the plate is turned and move
the same.
To adapt the same furniture for different doors, the plate is changed to the opposite
side of the lever by simply unscrewing the nut and reversing the plate.
A rib connects the posts and is designed principally to strengthen them.
The lever is sometimes pivoted to a post formed on the rose and held in position by
a washer and screw, the screws which hold the rose to the door being made indo-
pendent of the screw which holds the lever in place. In some cases the same screw
which holds the rose upon the door passes through the post and the end of the lever.
The advantage of forming the screw lugs in a line with the shank perforation in the
rose is that the strength is provided where it is needed and the pull upon the handle
is resisted directly by the screws.
A spring is provided which returns the latch to its normal latching position.
The knob-handle is sometimes formed in two parts united by an overlapping joint
around the periphery of the knob.
An outer fixed shank can be swedged in the rose, or cast integrally with the rose or
in some furniture be dispensed with entirely. Within the shank and turning therein,
is an inner shank cast integrally with the portion of the knob, through which the bolt
passes the head of which rests in a recess in the said portion of the knob.
A projection engages with the head of the bolt and prevents the said bolt from
slipping into the interior of the knob.
A nut screwed on the end of the bolt holds the lever actuating plate in position.
An opening is made in opposite sides of the door in a line with the latch through
which opening the bent ends of the pivoted lever project into the lock case and
engage with the latch.
The form of the pivoted lever and the plate may be varied, I deem it essential
however for the practical working of the invention that the said lever be pivoted
above the axis of the knob and shank.
By virtue of the construction of the mechanism hereinbefore described or any
equivalent thereof either movement of the knob, whether toward the right or toward
the left, is converted into but one movement of the latch operating lever, which draws
the latch from its latching or locking engagement.
In the specification filed with the application referred to at the beginning of this
specification a latch operating lever is illustrated which is secured to the end of the
shank and extends from above the lock mortise down within the furniture or rose,
opposite to the latch, at which point it enters the lock casing and engages with the
latch.
One object of this arrangement is to enable long screws to be driven into the solid
wood above the lock mortise through the escutcheon or rose to more securely attach
the same to the door.
In said specification, however the latch lever shown, can only be used with a handle
which must be turned in one direction to draw the latch.
The present invention is designed to attain the advantages of the depending lever
and also to permit the use of a rotating knob which is greatly desired by the public
the said mechanism allowing the rotation of the know in either direction similar to the
ordinary spindle and by virtue of the construction thereof causes either movement of
the knob to draw the latch as set forth abovo.
The depending lever in this invention also permits long screws to be inserted into

page_text: the solid wood above the lock mortise through the rose on each side of and in a line
with the knob shank, which directly sustain and resist the pull upon the knob.
I am aware that a lever has been pivoted within the lock case independent of the
furniture, and a finger projecting from a circular plate which is operated by a knob,
engaging with the lever on a supplemental lever in the lock case. By this con-
struction however the rose, knob &c. are and must be placed against and secured to
the door opposite to the lock mortise which is diametrically the reverse of my
construction and purpose.
In the device to which reference is made above, the mechanism for drawing the
latch consists of two levers, one of which is in permanent engagement with the latch
and the second with which the projecting arm engages, acts upon the first lever, both
of these being pivoted within the lock case; while in my device the lever is pivoted
to the furniture or rose outside of and entirely separate from the lock case.
Also in the old device the levers and the finger are formed separately, while in my
mechanism, the lover which is operated by the knob through the reversible plate or
equivalent mechanism and the finger that engages with the latch are forined in
one piece.
By securing the entire latch-operating mechanism to the furniture independently of
the locking or latching mechanism the construction and operation of the lock or latch
are greatly simplified and cheapened, and a much greater leverage is obtained which
renders the turning of the knob much casier.

page_text: 1. ORVELLAS HENRY GILBERT, of 19 Lombardy Street, in the City of Nowark, County
of Essex and State of New Jersey, United States of America, Manufacturer, do
hereby declare the nature of my invention for "IMPROVEMENTS IN LATCH OPERATING
DEVICES," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The invention relates to improvements in latch drawing mechanism and door
furniture generally, but has reference more particularly to improvements in a previous
invention for a similar purpose for which an application for letters patent of the
United States was filed Nov. 6, 1884, No. 147,252.
The primary object of the invention being to provide a latch actuating device which
can be secured to the door above the lock mortise and also permit the use of a knob
to operate the said latch actuating device so that in whatever direction the knob is
turned it will draw the latch.
The furniture is also made reversible for either right or left hand doors or
opposite sides of the same door.
The invention consists of a lever pivoted to a rose plate off the center of the axis of
revolution of the knob, &c., preferably above the same and operated by suitable means,
one form of which is illustrated in the drawing, described in the specification and
finally embodied in the clauses of the claim.
In said drawings, in which similar reference letters indicate corresponding parts in
each of the several views, figure 1 is a plan of the back or under side of the rose and
escutcheon of my improved furniture showing the relative position of the latch
operating mechanism; figure 2 is a view similar to figure 1, but showing a modified
construction adapted especially for cheap furniture; figure 3 is a section of figure 1
through line; and figures 4 and 5 are perspective views of the pivoted lever and
lever actuating plate respectively.
A in the drawing is the rose of the furniture to or within which the latch operating
mechanism is secured and arranged, and B is the escutcheon.
The rose and escutcheon may be cast in one piece or separately, being divided at
the point indicated by the dotted line z on figure 2.
When the rose is cast independently of the escutcheon, or when the rose and
escutcheon are formed integrally as indicated in figure 2, lugs or ears m are formed
on each side of the rose in a line with the shank perforation, through which the screws
pass that hold the rose to the door.

page_text: The latch actuating lever C is formed substantially as illustrated, consisting
essentially of a main portion c and a finger or bent end c which projects into the lock
case and engages with the latch L as indicated in figure 3.
The main portion c is preferably formed with an opening therein to allow sufficient
room for the nut on the end of the bolt which holds the parts together, and permits
the pivoted lever C to swing when operated by the handle, &c.
The lever C is preferably pivoted above the shank perforation or above the center
of the axis of revolution of the knob, and near the top of the rose or as far up as is
desirable to secure the requisite leverage and extending down within the rose below
the shank perforation swings freely therein.
To operate the lever C and cause it to draw the latch I employ a device D shown in
figures 1, 2 and 5 which is so constructed and arranged in relation to the knob, &c.,
as to draw the latch whether the knob is turned to the right or to the left and also
may be reversed so that the same furniture may be used on either right or left hand
doors.
To accomplish this the plate D is secured to and turns with the shank or bolt
passing therethrough, and extending out beyond the outside of the lever is provided
with posts or projections d, d', which engage with the lever when the plate is turned
and move the same as shown by the dotted lines on figure 1.
By reference to said figure it will readily appear that the lever will move in but
one direction whether the plate D is turned in one direction or in the other, in one
case the post d engages with the lever at c², in the other, the post d' ongages with
said lever at c³ and in both cases on the same side thereof.
To adapt the same furniture for the opposite side of the door, or for different doors,
the plate D is changed to the opposite side of the lever as indicated by the dotted lines
in figure 2, by simply unscrewing the nut and reversing the plate.
The rib d which connects the posts is designed principally to strengthen the
posts.
In figure 1 the lever C is pivoted to a post formed on the rose and held in position
by a washer e and screw f, the screws which hold the rose to the door being made
independent of the screw which holds the lever in place. In figure 2 the same
screw which holds the rose upon the door passes through the post and the end of the
lever.
The form shown in figure 1 is designed more especially for more expensive goods,
that illustrated in figure 2 for cheaper furniture.
The advantage of forming the screw lugs m in a line with the shank perforation in
the rose as indicated in figure 2, is that the strength is provided where it is needed
and the pull upon the handle is resisted directly by the screws.
S, figure 3, is a spring which returns the latch to its normal latching position.
As indicated in figure 3 the knob-handle is formed in two parts g, h, united by an
overlapping joint g around the periphery of the knob.
i is an outer fixed shank which in the figure is swedged in the rose, but may be
cast integrally with the rose or in some furniture be dispensed with entirely.
Within the shank i, and turning therein, is an inner shank ' cast integrally with
the portion of the knob, through which the bolt j passes the head of which rests in a
recess k in the portion of the knob as in figure 3.
g
A projection g² on the portion y of the knob engages with the head of the bolt and
prevents the said bolt from slipping into the interior of the knob.
A nut o screwed on the end of the bolt holds the lever actuating plate D in position.
An opening p is made in opposite sides of the door in a line with the latch through
which the bent ends of the lever C project into the lock case and engage with the
latch as shown in figure 3.
I am aware that the form of the pivoted lever C and the plate D may be varied, in
view of which I do not wish to limit myself to the identical mechanism shown, still
while the said parts may be changed and the lever operated by other means I deem it
essential for the practical working of the invention that the said lever be pivoted above
the axis of the knob and shank.

page_text: By virtue of the construction of the mechanism hereinbefore illustrated and
described or any equivalent thereof, either movement of the knob, whether toward the
right or toward the lift, is converted into but one movement of the latch operating
lever which draws the latch from its latching or locking engagement.
In a contemporaneous application, filed Nov. 6,1884, serial number 147,252,
referred to at the beginning of this application, is illustrated a latch operating lever
which is secured to the end of the shank and extends from above the lock mortise
down within the furniture or rose opposite to the latch at which point it enters the
lock casing and engages with the latch.
One object of this arrangement is to enable long screws to be driven into the solid
wood above the lock mortise through the escutcheon or rose to more securely attach
the same to the door.
In said application however the latch lever shown, can only be used with a handle
which must be turned in one direction to draw the latch.
In this application the invention is designed to attain the advantages of the
depending lever and also permit the use of a rotating knob which is greatly desired
by the public, the said mechanism allowing the rotation of the knob in either
direction similar to the ordinary spindle, and by virtue of the construction thereof
causes either movement of the knob to draw the latch as set forth above.
The depending lever in this invention also permits long screws to be inserted into
the solid wood above the lock mortise through the rose on each side of and in a line
with the knob shank which directly sustains and resists the pull upon the knob.
I am aware that a lever has been pivoted within the lock case independent of the
furniture and a finger projecting from a circular plate which is operated by a knob,
engaging with the lever or a supplemental lever in the lock case.
By this construction however the rose, knob, &c., are and must be placed against
and secured to the door opposite to the lock mortise which is diametrically the reverse
of my construction and purpose.
In the device to which reference is made above the mechanism for drawing the
latch consists of two levers, one of which is in permanent engagement with the latch,
and the second with which the projecting arm engages, acts upon the first lever, both
of these being pivoted within the lock case; while in my device the lever is pivoted
to the furniture or rose outside of and entirely separate from the lock case.
Also in the old device the levers and the finger are formed separately, while in my
mechanism the lever, which is operated by the knob through the reversible plate or
equivalent mechanism, and the finger that engages with the latch are formed in one
piece.
By securing the entire latch operating mechanism to the furniture independent of
the locking or latching mechanism the construction and operation of the lock or latch
is greatly simplified and cheapened and a much greater leverage is obtained which
renders the turning of the knob much easier.
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. In latch operating devices the combination of a rose plate having a shank
perforation therein; a latch actuating lever pivoted to said rose plate above the said
shank perforation or the axis of revolution of the knob, and extending down below
the said shank perforation, and having an end or finger which when the rose plate is
secured to the door projects into the lock or latch case and engages with the latch;
and a lever actuating plate connected with and operated by a rotating knob and
which engages with the latch actuating lever causing the same to draw the latch
whether the knob is turned to the right or to the left, substantially as and for the
purposes set forth.
2. In latch operating devices the combination with a lever pivoted within a rose
above the shank perforation and extending down below the said shank perforation
having a bent end adapted to engage with and actuate a latch, of a reversible plate
adapted to engage with either side of said pivoted lever and mechanism by means of

page_text: which said reversible plate is caused to engage with and operate said lever, for the
purposes set forth.
3. In latch operating devices in combination a rose plate; a lever pivoted within
said rose above the shank perforation therein and extending down below the said
perforation having a bent end adapted to engage with and actuate a latch; a
reversible plate having posts d d¹ thereon which engage with said lever; and a knob
handle with which said reversible plate is connected and by which it is operated, for
the purposes set forth.
4. In latch operating devices in combination, a rose plate; an outer fixed shank, i;
a knob composed of two portions h, g, the portion / being provided with an inner
shank having a recess & therein; a bolt; the head of which rests in the recess k;
a reversible plate secured to the inner end of the bolt provided with posts, d d'; and a
lever pivoted to the rose above the shank perforation, all said parts being arranged
and operating substantially as and for the purposes set forth.
