PROVISIONAL SPECIFICATION.
Improvements in Esoutcheons used for Look Furniture, and in the
Manufacture of the same.
I, JOHN JESSE JAMES, trading as Dutson & Co. of Whittall Street, Birmingham,
in the County of Warwick, Manufacturer do hereby declare the nature of my said
invention to be as follows:-
My invention has for its object improvements in escutcheons used for lock
furniture and in the manufacture of the same by which I am enabled to facilitate
the rapid production thereof with economy in cost. My invention is as follows:-
In the manufacture of escutchoons I commence with a tube formed from brass or
other metal into approximately the width of the outside largest portion of the
escutcheon required and in the other direction or length approximately the same
as the longest part of the escutcheons when finished. Both the top and bottom of
the tube is curved and the sides are straight or the section may be a long oval.
This tube may bo solid or braized.
I first cut it into short lengths approximately the depth of the escutcheon. I
then place each length in a die under a press or stamp the die having a centrò
peg as usual and force the metal into required shape. Such escutcheons may be
floated or otherwise finished and sold in this condition. In some cases however I
pass tho escutcheon through another process to form upon the outside part a flange
running either all the way round or only portions thereof. This flange is formed
by a side tool or tools cutting into it while at the same time a punch is brought
down to form the thin or bottom edge which forces the metal outwards to form the
flange.
I may also form the escutcheon from a sheet of thin metal by stamping out a
blank with roughed or plain outside edges. This blank is then raised under a
stamp or press to form an inner recess the form of the key and an outer flange
turned downwards. The bottom of the recess is then punched out and the
escutcheon finished. When these escutcheons are driven home the outer flange
enters the timbor and holds the escutcheons from coming out of position.

Improvements in Escutcheons used for Look Furniture, and in the
Manufacture of the same.
I JOHN JESSE JAMES trading as Dutson & Co. of Whittall Street, Birmingham
in the County of Warwick, Manufacturer of do hereby declare the nature of my
said invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-

the rapid production thereof with economy in cost. My invention is as follows:-

This tube may be solid or braized.
I first cut it into short lengths approximately the depth of the escutcheon. I
then place each length in a die under a press or stamp the die having a centre peg
as usual and force the metal into required shape. Such escutcheons may be floated
or otherwise finished and sold in this condition. In some cases howevor I pass the
escutcheon through another process to form upon the outside part a flange running
either all the way round or only portions thereof. This flange is formed by a side
tool or tools cutting into it while at the same time a punch is brought down to
form the thin or bottom edge which forces the metal outwards to form the flange.
I may also form the escutcheon from a sheet of thin metal by stamping out a
blank with roughed or plain outside edges. This blank is then raised under a
stamp or press to form au inner recess the form of the key and an inner flange
turned downwards. The bottom of the recess is then punched out and the
oscutcheons finished. When these escutcheons are driven home the outer flange
enters the timber and holds the escutcheons from coming of position.
In order that my invention may be clearly understood and more easily carried
into practical effect 1 have appended hereunto a double sized sheet of drawing
upon which in seventeen figures I have illustrated my several modes of producing
the escutcheons but I do not confine myself either to the sizes shown or to the
exact configurations as these may be varied without departing from the principle of
the invention.

escutcheons.

.
Figure 10 is a plan Figure 11 a side elevation and Figure 12 a cross section on
dine 9-10 of an escutcheons made from sheet metal instead of from a drawn tube.
Figure 13 is a plan of a strip of metal from which I form an escutcheon.
Figure 14 represents the first operation. Figure 15 shows the escutcheon when
finished and Figure 16 a section of the said finished escutcheon on line 11-12.
The first process in the manufacture of my escutcheons is shown by A. Figure 1
and 2 which is produced by drawing a brass or other metal tube through drawing
tools of the required shape and size to be roughly the size of the escutcheon when
finished. The second process is to cut this tube into slices by a small saw or
otherwise the length or thickness of each slice being sufficient to supply the
mecessary metal to produce a finished escutcheon. These slices are represented by B
Figure 3 and 4 and they are of course parallel that is to say the same thickness
of metal throughout as seen in section at Figure 4. The third process is to place
these parallel slices in a taper die and by means of a blow or pressure upon the top
to force the parallel piece B into the tapered recess thus giving to it the necessary
external configuration as regards its top and bottom size which is shown by B¹
Figures 5 and 6 suitable dies for this purpose are so well known by toolmakers as
not to require description and thus remark further applies to the sliding tools which
form the recess or recesses and which I call the fourth process. The result of the
fourth process is shown by B' Figures 7 and 8 the recess b being formed by
placing the oscutcheon upon a peg which fits the inside, and which remains there
while two side jaws are brought to bear upon it externally thus making the recess
or recesses 6. The object of the recess or recesses is to prevent the escutcheons
coming out of its position when driven home but to further assist it I may sirrate

page_text: the lower edges as shown by Figure 9 so as to form teeth which enters the
timber or other material into which the escutcheons is driven the hole in this case
not being made the full depth of tho escutcheon. 1 may turn these teeth 61
ontwards so that there will be a tendency for them to slightly curl round and
enter the material into which they are driven in a curving diagonal direction and
if much curl is given the teeth would take almost a horizontal direction thus
securing the escutcheon thoroughly against withdrawal by the use of the key. In
some cases.I may dispense with the horizontal recess or recesses 6³ that is to say I
may use 6 alone in conjunction & or I may use b₁ alone. When I make my
escutcheons from sheet metal such as C by a raising or cupping process which is
represented by Figures 11 and 12.1 first cut out a blank of the necessary size to
produce the escutcheon. Next I place it in dies and raise the sides. Next I flange
it to form the front part c'. I then cut out the bottom to the desired size of the
key hole. These escutcheons may be sirrated as described herein before as
applied to Figures 7 and 8 and 9. Another mode of forming the escutcheons from
sheet metal is represented by Figures 13, 14, 15 and 16 in which case I first cut
out a strip as shown by Figure 13. I then bend it round by well known tools into
rough shape as shown by Figure 14. It is then placed in a die and flanged down
as seen by Figure 15. This kind of escutcheon may also be treated as herein-
before described as applied to Figures 7, 8 and 9 to produce recesses 6 or hor
both. In the latter case that is of the escutcheon shown by Figures 13 to 16 I
may leave the bottom, quite open or bottomless as shown by K Figure 17 and it
would answer the purpose well enough for cheap work. By the last two modes the
entrance corner & may be rounded which is an advantage for putting the key in.
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 :-
-
The improvements in escutcheons used for lock furniture and in the manufacture
of the same substantially as herein set forth and as illustrated by the seventeen
figures upon the accompanying drawings.
