PROVISIONAL SPECIFICATION.
Improvements in and relating to the "Joggling" or Notching of
Ships' Frames and like Angle Bars.
I, ALEXANDER LAMBIE, Manager to Russell and Company, Shipbuilders, Port
Glasgow, Renfrewshire, do hereby declare the nature of my invention to be as
follows:-
"
This invention has reference to and comprises an improved method and appliances
for "joggling or notching ships' frames and like iron or steel angle bars, and
whereby a great saving of labour will be effected as well as increased efficiency of
workmanship.
In existing steamers and sailing vessels where "joggling" or notching of the
frames has been adopted, it is usual to perform the same at an ordinary smith's fire
by heating the angle bar and "joggling" or notching the same over the block or
anvil, and which causes considerable injury to the material.
By my improvements 1 use a bolster or base frame having a longitudinal groove
or channel through its centre. Over the one edge of the groove at centre part I fit or
form a projecting up steel or other matrix, and in the centre of groove I fit a tool or
tongue piece.
This tongue piece would be made the same length as the matrix, and formed of
sufficient depth to suit the depth of "joggle" or notch desired. It is secured by
fitting it into a square hole at bottom of groove, and fixing it by a pinching screw
from the one side of groove.
The other side of groove at centre of bolster opposite the matrix and tongue piece
would be open and a portable block with a steel face would work in it.
This block would be actuated by a hand screw spindle working through the eye of
a crosshead which swivels on fixed bolster, all so as to move and keep the angle iron
passing through the groove up against the matrix on opposite side of groove; but
instead of a screw a hydraulic ram may be used to work the moveable block.
The die tool would be secured to the vertical planger or ram of a hydraulic or
other press.
In using this method the angle bar is placed in the groove of the bolster and
the vertical flange of angle bar bears hard on the tongue piece while at the same
time the angle bar is jammed by the screw block and pressed into the form of
"joggle" or notch required by the hydraulic or other press.

I, ALEXANDER LAMBIE, Manager to Russell and Company, Shipbuilders, Port

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say :-

In existing steamers and sailing vessels where joggling or notching of the
frames has been adopted, and for joggling angle bars, it is usual to perform the
same at an ordinary smith's fire by heating the angle bar and joggling or notching
the same
over the block or anvil and which causes considerable injury to the
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings in which Figure 1 is a plan view of my
improved appliance, Figure 2 is a sectional view of same taken on the line 1-1 and
Figure 3 is a sectional view as taken on line 2-2 at right angles to Figure 2. While
Figure 4 is a side elevation showing the hydraulic rain and die tool and Figure 5¡is
a sectional view showing. a bar in position.
Referring to these drawings:-
By my improvements I use a bolster or base frame A having a longitudinal
groove or channel A' through its centre. Over the one edge of the groove A' and
on the top of the transverse web A' and at its centre part, I fit or form a pro-
jecting up steel or other matrix or block B and in the centre of the groove. Â¹ I
fit a tool or tongue pieces C.
This tongue piece C would be made the same length as the block B, and formed
of sufficient depth to suit the depth of joggle or notch required, or size of iron
being operated upon. It is secured by fitting it into a recess at bottom of groove
and fixing it by a screw or screws to the side of the groove. The other. side,of
groove A, opposite the block B and tongue piece C at centre of bolster, would i
be open and a portable block D with a steel face D' would work within side
cheeks A formed on the: bolster A.
This block would be actuated by a hand screw spindle E working through the
eye of a crosshead F which might be made to swivel on fixed bolster but preferably,
as shown, is secured to the side checks A, all so as to move and keep the angle
iron passing through, c
or placed within the groove up against the opposite side.of
groove and hold it there while the joggling is effected, but instead of a screw an
ordinary hydraulic r
ram may be used to work the moveable block D. The die
stool G formed as a block having a steel face Ginserted into a dovetailed slot G³,
and of a size to suit the depth of joggle required, would be secured to the vertical
plunger or ram H of a hydraulic, or it might be other press, erected over the
bolster A and secured by the pillars H to any suitable foundation carrying the
bolster. In using this method the angle bar I is placed in the groove,A¹ of
the bolster A and the vertical flange of angle bar bears hard on the tongue
piece C as shown in Figure 5, while at the same time the angle bar is jammed by
the screw block D and pressed into the form of joggle or notch required by the
hydraulic or other press carrying the die tool.
Instead of having the bolster in the horizontal position and erecting the hydraulic
ram vertically over it, it may be placed in a vertical or inclined position and have
the hydraulic ram erected in a position to correspond with same, and secured to it
in any ordinary manner.
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
