WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN UMBRELLAS." A. communi-
cation by Jean Antoine Dussud and Antonio Testacuzzi, both of Paris, France.
This Invention relates to improvements in the manufacture of top notches and
slides for umbrellas, a top notch being that part of an umbrella into which the ends
of tlio framework are fastened.
Hitherto these parts have always been constructed with a cast metal ring which
is afterwards soldered to a collar or tube, and the openings in the said ring, in
which the ends of the rods or branches forming the framework fit, are made by
a cutter. This method of manufacture takes much time and is consequently
expensive.
This Invention is designed to obviate these disadvantages, and in carrying the
same into practice I form these parts of an umbrella by cutting or punching out the
pieces of metal and beating or chasing them.
In order that the said Invention may be more clearly understood I have shewn
in the accompanying Drawings on an enlarged scale, and as examples, only a slide
or runner and top notch, constructed according to my improved method, with two
pieces or blanks.
Figure 1 shews a plan and longitudinal section of the first piece a cut out of a
piece of metal to form the collar and one-half of the slotted ring; this cutting out
is the first operation.
Figure 2 shews a plan and a section of the piece which has undergone a first
beating and shaping process, that being the second operation.
Figure 3 shews a plan and a section of the same piece, the collar 6 having
been formed by the second beating or shaping process, which is the third operation.
Figure 4 shews a plan and a section of the same piece after the fourth operation,
the cutting out tool or punch having formed the slots or openings c and determined
the diameter.
Figure 5 shews a plan and a section of the same piece after the fifth operation,
the bottom & removed.
Figure 6 shews a plan and a section of the second piece e, which has been cut

page_text: out of a piece of metal, the first operation; this piece forms the second part of the
ring.
Figure 7 shews a plan and a section of the same piece after being subjected to the
first beating or shaping process, or second operation.
Figure 8 shows a plan and a section of the same piece after the third operation,
in which the cutting or punching tool has formed the slots or openings fand cut
the piece to the desired diameter.
Figure 9 shows the same piece with the bottom part g removed, which is done by
the cutting or punching tool at the fourth operation.
Figure 10 shows a vertical central section of the two pieces a and e (which have
been cut out and beaten to shape) united to complete the top notch.
Figure 11 shows a vertical central section of the same top notch, the two pieces
having been joined together by a flange h formed by means of the cutting tool or
by a lathe.
The two pieces may also be united by soldering, and in this case they are
mounted, as shown in Figure 10, or they may be joined together by means of one
or more pins or rivets.
In order to rivet together the two pieces I provide on the piece a, Figure 12, by
means of the cutting or punching tool mortices i, and on the piece e, Figure 13,
tongues or tenons j, the said tongues or tenons entering into the mortices i when
they are beaten down by the beating tool, the effect being shown in Figure 14.
The joining together of the two pieces a and e by either method forms the top
notch with collar.
For manufacturing ordinary slides or runners, I take a piece of metal, as shown
nt, Figure 15, which has been cut out to shape, and in which has been formed by
the same operation a slot for the passage of the stop spring.
Figure 16 shows a side view of the piece k after being subjected to the first
operation of the beating tool.
Figure 17 shows the same piece after the second operation, the tube made and the
two parts united by soldering, rivetting, or otherwise.
Figure 18 shews a vertical section of this tube m with flange n at its base, made
by the cutting out tool. The tube on thus produced is soldered, rivetted, or
otherwise fastened to the collar b, Figure 10, of the top notch to form the slide.
Figure 19 shows a vertical central section of a tube for a slide or runner of
somewhat different construction. This tube which is fitted on the collar b of the
top notch, Figure 10, is provided with a rim o, for the purpose of uniting the said
tube, as shown in the Drawing.
Figure 20 shows a vertical central section of a top notch with a tube joined to
it, Figure 18, these two pieces being united and forming the ordinary slide or
runner.
Figure 21 shews a vertical contral section of a top notch with the slide or runner
of somewhat different construction attached.
