Improvements in the Manufacture of Flush Lifts and Flush Drawer
Handles.
I, PHINCHAS EDWARD AYTON, of the Firm of Thomas Pemberton and Sons,
of Livery Street in the City of Birmingham, Manufacturer; do hereby declare the
nature of this invention to be as follows:-
My invention relates to lifts, handles or pulls for windows, drawers, shutters
and the like, known in commerce as "flush lifts" or "flush drawer handles."
The said flush lifts, handles or pulls consist of a vertical plate with a set back
and longitudinal sunken niche-shaped recess about its middle, forming a hand hole,
wherein the fingers of a hand are placed for lifting a sash of a window, the
lifting into position and the removal of shutters, or the pulling out of drawers and
the like.
Now the hand holes of such lifts, handles or pulls, when made in a piece with
the flange or attachment plate, have no top and bottom set back pocketed parts for
the fingers of a hand to take within, so as to give a grip or "hold
pulling out.
"
on lifting or
According to my invention I make the said flush lifts or handles from thin sheet
metal, and with the top and bottom parts of the hand-hole set back or bulged
inwards beyond the plane of the boundary edge of the entrance, that is, the said
top and bottom parts are pocketed or extended upwardly and downwardly in the
direction of the front plate so that the top and bottom edges of the hand-hole
entrance horizontally overhang the inside top and bottom walls or parts of the
hand-hole.
In carrying out the manufacture of my said flush lift, I take a thin sheet metal
plate, of sufficient size to form the lip and I sink longitudinally within the middle
of the same, a niche-shaped sinking, consisting of a recess, having its walls semi-
circular in cross-section and terminated at the ends by slightly tapered walls.
In the formation of the sinking, the walls have to be slightly tapered to allow
the tools to properly leave the same, in consequence of which no set-back pocketed
parts can be formed by the ordinary tools.
The partially-formed flush lift or handle is then operated upon as follows:-
After being placed within a suitable holding bed die or dies provided with
Euitable clearances to admit of the displacement of the metal of the walls of the
hand-hole, a tool then enters the mouth of the said hand hole, and on being brought
down, bulges the wall at cne side and that adjacent to the bottom edge backwards
into a set-back trough or long pocket, hence the production of a finger grip or
hold.
The lift or handle is then turned over or brought round and the other and top
side operated upon in the same fashion as the bottom side.
As a still further form of my invention, I curve the walls of the body at their
junctions with the ends and then by an upsetting or pressing tool, I force the walls
of the hand hole into an elliptical figure, whilst the shape of the inside is preserved
by a he-tool placed in position.
The upsetting spreads the metal outwards and forms the pocketed top and
bottom hand-hold channels.

Improvements in the Manufacture of Flush Lifts and Flush Drawer
Handles.
I, PHINEHAS EDWARD AYTON, of the Firm of Thomas Pemberton and Sons, of
Livery Street, in the City of Birmingham, Manufacturer, 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 lifts, handles or pulls for windows, drawers, shutters
and the like, known in commerce as Alush lifts or flush drawer handles."
The said Hush lifts, handles or pulls consist of a face plate with a set back and
longitudinal sunken niche-shaped recess about its middle, forming a hand hole,
wherein the fingers of a hand are placed for lifting a sash of a window, the lifting
into position and the removal of shutters, or the pulling out of drawers and
the like.
"
Now the hand holes of such lifts, handles or pulls, when made in a piece with
the flange or attachment plate, have no top and bottom set-back pocketed parts for
the fingers of a hand to take within, so as to give a grip or
"hold
on lifting or
pulling out.
According to my invention, I make the said flush lifts or handles from thin sheet
metal, and with the top and bottom parts of the hand-hole set back or bulged
inwards beyond the plane of the boundary edge of the entrance, that is, the said
top and bottom parts are pocketed or extended upwardly and downwardly in the
direction of the front plate so that the top and bottom edges of the hand-hole
entrance horizontally overhang the inside top and bottom walls-or parts of the
hand-hole.
Figure 1 of the accompanying drawings represents a sheet metal hand-hole flush
lift made according to my invention. The dotted lines in the said figure represent
the top and bottom boundary walls of the sinking, which form, as it were, shallow
trough-shaped pockets. for the fingers to take into when an object to which the lift
or handle is attached is being lifted or pulled out.
Figure 2 represents a cross section upon the dotted lines - Figure 1, showing
the pocketed construction of the lift or handle.
Figure 3 represents an end elevation of the said lift or handle.
Figure 4 is a longitudinal section through the hand-hole part of the said flush
lift upon the dotted lines A Figure 2, and looking into the hand-hole.
In Figures 1 to 4, a is the front or attachment plate, with attachment screw
holes a', made through the corners of the same. a is the hand hole, with opposite
ends a³, and set-back, pocketed or channelled top and bottom parts a'.
In carrying out the manufacture of my said flush lift I take a thin sheet metal
plate, Figure (of which Figure 6 is an edge view) of sufficient size to form the
lift and sink longitudinally within the middle of the same, a niche-shaped
sinking, as represented in elevation in Figure 7 and in section upon the line B in
Figure 8, consisting of a recess, having its walls semi-circular in cross-section and
terminated at the ends by slightly tapered walls.
Figure 9 represents a cross section of the partially formed lift or handle, with
the handle hole or niche made deeper.
Figure 10 represents a like section as Figure 9, but with the hand hole recess
further sunken.
Figure 11 represents a like section as the three preceding figures, but with the
hand-hole recess. fashioned to the full required depth and having a figure given to
it such as ordinary sinking tools would effect.
Figure 12 is a front elevation of Figure 11. In these two figures, a is the flange
plate, a, the band hole part, a' the ends thereof and as the top and bottom walls.

page_text: The partially-formed Alush lift or handle Figures 11 and 12 is then further
operated upon as follows:-
After being placed within a suitable holding bed die or dies, provided with
suitable clearances to admit of the displacement of the metal of the walls of the
hand-hole, a tool then enters the mouth of the said hand hole, and on being brought
down, bulges the wall at one side and that adjacent to the bottom edge backwards
into a set-back trough or long pocket, hence the production of a finger grip or
hold.
The lift or handle is then turned over or brought round and the other and top
side operated upon in the same fashion as the bottom side.
Figure 13 represents the tools employed in the forming of the set-back finger
grips or holds of the hand-hole of the said flush lifts and the said tools are shown
in operation and as forming the grip upon one side of the hand hole.
In this figure, is the flange or front plate, a' the hand hole, as the ends, and
as the unoperated upon side, whilst a' is that part of the said side which is formed into
a grip or hold. is the top tool worked by a press or other means, 61 is the acting
end or nose of it, and c is the lower tool or die, having a concaved and sunken
seating c¹, to the shape of which the metal of the top and bottom sides of the hand
hole is made to conform.
The formation of the finger grips or holds is conducted as follows:-
The partially formed hand hole Figures 11 and 12 is taken, and placed longi-
tudinally within the lower die, with the nose of the upper tool taking into the hand
hole recess.
Then on the upper tool descending, the metal of one side is then
pressed or bulged back into the shape desired. The lift is then turned over and
the same operation is repeated upon the other side.
Instead of forming finger grips upon both the sides of the hand holes, they may
be formed upon one side only of the same.
The front plate is finished by clipping the edges, either before or after the
recessing of the hand grips.
As a still further form of my invention, I curve the walls of the body at their
junctions with the ends, and then by an upsetting or back pressing tool, I bulge or
force the walls of the hand hole into an elliptical figure by reducing the depth,
whilst the shape of the inside is preserved by a he-tool placed in position.
The upsetting spreads the metal laterally and forms the pocketed top and bottom
finger-grip or hold channels.
Figure 14 represents in elevation, partly in section, a flush lift made according
to the last-named form of my invention.
Figure 15 represents a transverse section upon the dotted line C.
Figure 16 represents a like section as Figure 15 but upon the dotted line D.
a is the front plate, a² the hand hole, a³ the ends and at the finger grip recesses.
at top and bottom, whilst a are the plain unbulged parts of the top and bottom
walls.
In forming the pocketed or inwardly-bulged grips a hand hole, alike in section
to Figure 16 is taken, and then by forcing inwards the middle part a', of the back
walls into the shape represented in Figure 15, a sheet metal lift with finger grip.
recesses is formed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
First. A sheet metal flush lift, or drawer or like handle, with the hand hole
having top, or bottom, or top and bottom, finger grip recesses or holds, substantially
as described and set forth.
Secondly. Forming the finger grips or holds in the hand holes of sheet metal
flush lifts, or drawer or like handles, in the way and by the means substantially
as described and set forth in Figures 1 to 13.

page_text: Thirdly. Forming the finger grips or holds in the hand holes of sheet metal
flush lifts, or drawer or like handles, in the way and by the means substantially as
described and set forth in Figures 14, 15 and 16.
