PROVISIONAL SPECIFICATION.
An Improved Method of Making Roses for the Loose End of
T. K. Mace's Expired Patent Lock Furniture, No. 804, dated
20th March, 1867.
We RICHARD THOMAS GROCOTT and ALEXANDER PROSSER DICKINSON of
the Firm of Gaskell & Grocott Whitehall Works Longport, Stoke-on-Trent in
the County of Stafford China Lock Furniture Manufacturers do hereby declare the
nature of this invention to be as follows:-
Our invention consists of an improved method of making roses (known in the
trade as "loose end roses ") for Mace's expired patent lock furniture.
We will now describe our invention.
To make description clear we refer to diagrams.
Fig. 1 shows plan of same.
Fig. 2 shows elevation of section through A B Fig. 1.
Fig. 3 shows elevation of section through C D Fig. 1.
We take a piece of rolled metal, either of copper, brass, iron or steel of
convenient dimensions. We then stamp or press the said piece of metal by the aid
of dies and tools until the part GH, G H G" H" is raised to a sufficient height
(about) which height will enable us to form a groove E F E F E" F" of a
required depth (about ").
This said depth to be determined by the thickness of the set screw, which screw
has to pass through the said groove E F, into the neck of knob, whilst the rose is
against the door, and the loose end knob is screwed or forced into its proper
position for fixing to the spindle and the door.
In forming the said raised part GH G'H' GH" we turn back the metal from
the front, to beyond the depth of the said groove EF EF¹ E" F", to the position
as shown in Fig. 2 J K Fig. 3 J'K'.
This latter part, together with the forming of groove EF E F E F in dies
or tools has not hitherto been made by this process, although it is the absolutely
essential part for keeping the set screw in its place, when the knob is at work in
the lock on the door.
The outer part LM LM L" M" may vary in shape or pattern.

Fig. 1 shews plan of same.
Fig. 2 shews elevation of section through A B Fig. 1.
Fig. 3 shews elevation of section through CD Fig. 1.
We take a piece of rolled metal, either of copper brass, iron, steel or alloys of
these metals, of convenient dimensions. We then stamp or press the said piece of
metal by the aid of dies and tools until the part G H G H G" H" is raised to a
sufficient height (about of an inch), which height will enable us to form a.
groove EFE F E F of a required depth (about of an inch).
The said depth of the said groove must be determined by the thickness of a set
screw which must pass through the said groove into a tapped hole in the neck of
the said knob whilst the rose is against the door or lock and when the said knob is
screwed or forced into position for fixing to its spindle, on the door.
We also stamp or press back the metal from the front GH G' H¹ G" H" to
the level of or beyond the depth of the said groove to the position as
shewn J K J'K'.
The outer part L M L' M¹ L"M" may vary in shape or pattern.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what

1, each rose made from one piece of rolled metal
2, stamped or pressed with a groove F E F¹ En Fu
3, with the metal forced back from the front G H G H G" H" to the level of
or beyond the depth of the said groove.
