This Invention relates to certain improvements in the manufacture of notches
and runners for umbrellas or which may be applied to other similar articles: the
improvements being of advantage in economizing material, labor, and cost of
production.

According to the present improvements these articles are stamped or formed
'froin sheet metal, instead of. being made of cast metal as formerly, by the aid of
properly formed and correspondingly shaped tools, consisting of a plunger, and a
bed, made with such slots, holes, or cavities, and heads, as to give the usual or
required formation to these articles. These means avoid any necessity, for dressing
the articles, and effect the production of a superior and cheaper article.

JOHN SAMBROOK of N° 14 Loveday Street Birmingham in the County of
Warwick Gun Implement Maker, do hereby declare the nature of my invention
for "A NEW OR IMPROVED MANUFACTURE OF UMBRELLA NOTCHES AND RUNNERS
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This Invention relates to certain improvements in the manufacture of notches
and runners for umbrellas or which may be applied to similar articles, such as
sunshades parasoles and the like, the improvements being of advantage in econo-
mizing material labour and cost of production.
According to the present improvements these articles are stamped or formed
from sheet metal instead of being made of cast metal, as formerly, by the aid of
properly formed correspondingly shaped tools, consisting of a plunger and a bed
made with such slots, holes or recesses and projections as to give the usual beds or
jaws for securing pivoting or hinging these articles.
These means avoid any necessity for drilling the articles and effect the production
of a superior and cheaper article.
In order that my invention may be more clearly understood and carried into
practical effect with greater facility I have appended hereunto a sheet of drawings
upon which illustrations of my improvements about twice the ordinary size are
given.
Figure 1: is a side elevation of one of my improved runners or top joints with
cover or cap removed.
Figure 2: is a plan of the same.
Figure 3: shows the cover screwed upon the part shown by Figure 1.
Figure 4 is a part section through one hole showing how the whole is tied
together.
In Figure 4, A is the rib and B the ball which slides through the slot C after all
are in the cover D is screwed on to cover all.
Now hitherto the part Figures 1 and 2. have been cast as a block and the
recesses or ball sockets K were drilled into the flange and then the slot C were
sawn or otherwise cut in.
Now according to my invention I make the part Figure 1 from a blank or plate
flanged down which is afterwards recessed by the tool Figure 5, the projections E
producing them in a corresponding bolster.
After this is done another tool stamps the slots C thus finishing the part Figures 1
and 2 without any hand inanipulation.
In the same manner ears H may be brought down instead of sockets to receive
a jaw at the end of the rib. In this case the projections E on the tool Figure 5
would require shaping accordingly but otherwise the process, and effect would be
the same. Figure 7 shews another method of carrying out my invention..

page_text: 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
The manufacture of the part of runners or joints shewn by Figures 1 and 2 and 6
in which the runner is made from sheet metal by flanging or otherwise forming a
flange which is afterwards stamped or pressed into recesses K and C or jaws H to
receive the ribs substantially as herein set forth.
