Improvements in and relating to Machines for "Joggling" or
Notching Ships Frames and like Angle Bars or Plates.
I, ALEXANDER LAMBIE, Manager to the Firm of Russell and Company, Ship-
builders, Port Glasgow, Renfrewshire, do hereby declare the nature of my
Invention to be as follows:-
November 8
This Invention has reference to improvements in and relating to machines for
"joggling" or notching ships frames and like angle bars or plates, and is essentially
a developinent of my prior patent No. 21,158 1805
According to my present improvements, I employ a moveable block on the top
of which rests the angle bar or plate to be joggled. The tongue piece which is
also portable is placed adjacent to the inner side of this block, and a tapered wedge
is fitted underneath both the moveable block and tongue piece and is made moveable
by a hand screw or other gear, so as to raise or lower the block and tongue piece
to regulate the depth of joggle desired. A slide block, with steel face is fitted
on the opposite side of the tongue piece, the angle bar to be joggled being placed
between it and the upper part of wedge actuated moveable block, and this slide
block is actuated by a hand screw spindle or other gear to adjustably move towards
or away from the bar to be treated, while a pinching pin would pass through a
hole in the block to keep the tongue piece in firm position.
The die plate would be bolted to the lower end of an hydraulic ram working in
a cylinder bolted to vertical main frame of machine, and the T piece used for
joggling angle bars would be secured in a corresponding shaped recess in it.
For joggling plates, a portable block would preferably be fitted behind the other
block and be operated by wedges from both sides of the machine, while an auxiliary
angle iron or like shaped die plate would be screwed to the end of main die plate
for fastening liner when joggling plates.

builders, Port Glasgow, Renfrewshire, do hereby declare the nature of my
[D077

page_text: invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement, that is to say:-
"
This Invention has reference to improvements in and relating to machines for
joggling" or notching ships frames and like angle bars or plates and is essentially
a development of my prior patent No. 21158 Nov
18:05
And in order that my said invention and the manner of carrying same into
practice may be properly understood, I have hereunto appended a sheet of explana-
tory drawings in which Figure 1 represents a side elevation broken away at the
upper part and partly in section of a machine às constructed in accordance with
my improvements. Figure 2 is a horizontal section as taken near the line 1-1
of Figure 1, and Figure 3 is a front end elevation at right angles to Figure 1.
Figure 4 is a detached sectional elevation showing the essential parts of the machine
as operating on an angle iron instead of joggling a plate as in Figure 1, and
Figure 5 is a front end view at right angles to Figure 4. Figure 6 is a detached
sectional view to an enlarged scale showing a single wedge for operating the
block e instead of the double wedge arrangement shown in Figures 1 to 3.
Figure 7 shows front and back views of the sliding block d. Figure 8 shows
side and front views and a plan of the moveable block a, and Figure 9 shows
front and side views of the tongue piece b.
Referring to these drawings:-
According to my improvements, I employ a moveable block a on the top of
which rests the angle bar z or plate z to be joggled. The tongue piece b which
is also portable is placed adjacent to the inner side of this block a and a
tapered
wedge c is fitted underneath both the moveable block a and tongue piece and
is made moveable by a hand screw c¹ or other gear, so as to raise or lower the
block and tongue piece 6 to regulate the depth of joggle desired. A slide
block d which may have a steel face is fitted on the opposite side of tongue
piece b the angle bar z to be joggled being placed between it and the upper part
of wedge actuated moveable block a and this slide block d is actuated by a hand
screw spindle d' or other gear to adjustably move towards or away from the
bar z to be treated, while a pinching pin would pass through a hole in the
block to set the tongue piece bi in firm position. A recess a shown more
particularly in Figure 8 is formed in the face of the block a for the tongue
piece to fit within, and a recess may be formed in the block d to receive the
projecting part of tongue piece b.
The die plate A is bolted to the lower end of an hydraulic ram A' working
in a cylinder A bolted to vertical main frame Z of machine.
As shown in Figures 1, 2, 3 and 6, for joggling plates, a portable block e
would preferably be fitted behind the other block a and be operated by wedges e¹
and screw spindles from both sides of the machine. A steel plate e would
preferably be fitted over the block e, when joggling plates z¹ as shown in the
figures.
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 machine for "joggling" or notching ships frames and like angle
bars or plates in which are employed the combination of a moveable block a, and
actuating wedge c substantially as set forth.
Second. In a machine of the class described in Claim 1, the combination of
a moveable block a, tongue or equivalent piece b, and actuating wedge c
substantially as set forth.
Third. In a machine of the class described in Claim 1 the combination of a
sliding block d substantially as and for the purposes set forth.
Fourth. In a machine of the class described in Claim 1, the combination of a

page_text: portable block e operated by wedges el substantially as and for the purposes set
forth.
Fifth. The arrangement and combination of parts constituting a machine for
"joggling" or notching ships frames and like angle bars or plates, substantially
as herein described in reference to and shown in the accompanying drawings.
