Punching Machines to Different Attitudes.
We, RALPH HART TWEDDELL, of No. 14 Delahay Street, Westminster in the
County of Middlesex, Engineer, JAMES PLATT and JOHN FIELDING both of Atlas
Works, Gloucester, Engineers do hereby declare the nature of this invention to be as
follows:
Our invention relates to apparatus applicable to portable rivetting and punching
machines for the purpose of adjusting them to different attitudes so as to direct their
tools in the line of the holes to be punched or the rivets to be headed, the adjusting
apparatus being worked by pressure of fluid, which may be the water under pressure
or other fluid used for working the punching or rivetting tools themselves. Thus the
attendant, instead of having to apply the power necessary for altering the attitude of
the machine, has only to manipulate the valves that govern the passage of the acting
fluid.
For this purpose, the machine is hung from a suspending frame by a double joint
so that it can swing in two vertical planes at right angles to each other. The pin of
one of these joints has fixed on it a pinion gearing with a rack on the rod of a piston
or plunger that works in a cylinder on the suspending frame. By manipulating
suitable valves, the fluid under pressure is caused to propel this piston or plunger in
either direction, and its rack causes the pinion to turn more or less, swinging the
machine to a greater or less inclination in the one vertical plane. On the fixed pin
of the other joint is also fixed a pinion gearing with a rack worked by the piston or
plunger of a second cylinder on the machine itself. By the movement of this piston
or plunger, resulting from fluid pressure, its rack, in travelling along the fixed pinion
with which it gears, causes the machine to swing to a greater or less inclination in the
other vertical plane.
According to a modified arrangement, dispensing with one of the cylinders and
racks, the rack of the cylinder on the machine gears with a pinion that is free on the
pin of the second joint but can be clamped thereon. This pinion has attached to it
a bevil pinion garing with another bevil pinion that is fixed to the suspending frame
0

page_text: having its axis in line with the first joint. When the rack pinion is free on its pin,
the movement of the rack turning it and its bevil pinion causes the latter to travel
round the second stationary bevil pinion thus swinging the machine in the one
vertical plane. When the rack pinion is clamped on its pin, as owing to the engage-
ment of the bevil pinions it cannot turn, the rack when it moves has to travel round
the stationary pinion, thus swinging the machine in the other vertical plane. The
suspending frame, being hung by a swivel, or mounted on a vertical axis, can he
turned round in the horizontal plane and can be raised or lowered by a crane or
otherwise, and thus the punching or rivetting machine being capable of angular
adjustment in the horizontal plane, and in two vertical planes at right angles to one
another, besides being capable of being raised or lowered, can have its operating tools
directed in any desired line, the angular direction being adjusted according as the
valves of the cylinders above mentioned are manipulated.

page_text: Fluid Pressure Apparatus for Adjusting Portable Rivetting and
Punching Machines to Different Attitudes.
We, RALPH HART TWEDDELL, of No. 14 Delahay Street, Westminster, in the
County of Middlesex, Engineer, JAMES PLATT, and JOHN FIELDING, both of Atlas
Works, Gloucester, Engineers, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascertained
5 in and by the following statement:-
Our invention relates to apparatus applicable to portable rivetting and punching
machines for the purpose of adjusting them to different attitudes, so as to direct their
tools in the line of the holes to be punched or the rivets to be headed, the adjusting
apparatus being worked by pressure of fluid, which may be the water under pressure
or other fluid used for working the punching or rivetting tools themselves. Thus the
attendant, instead of having to apply the power necessary for altering the attitude of
the machine, has only to manipulate the valves that govern the passage of the acting
fluid.
For this purpose we construct the apparatus as shown on Sheet I of the
accompanying drawing. Fig. 1 is a side view. Fig.
vertical section of the upper arm of the suspending frame. Fig. 4 is a sectional plan
an end view. Fig. 3 is a
of the double joint with fluid passage through it.
The machine A is hung by a suspending frame B by a double joint so that it can
swing in two vertical planes at right angles to each other. The pin of one of these
joints has fixed on it a pinion C gearing with a rack on the rod of a piston or plunger
that works in a cylinder D on the suspending frame B. By manipulating suitable
valves, the fluid under pressure is caused to propel this piston or plunger in D in
either direction, and its rack causes the pinion C to turn more or less swinging the
machine to a greater or less inclination in the one vertical plane. On the fixed pin of
the other joint is also fixed a pinion E gearing with a rack worked by the piston or
plunger of a second cylinder F on the machine A itself. By the movement of this
piston or plunger, resulting from fluid pressure, its rack, in travelling along the fixed
pinion E with which it gears, causes the machine A to swing to a greater or less
nclination in the other vertical plane.
According to a modified arrangement shown in Sheet II, Fig. 5 being a side view,
Fig. 6 an end view, dispensing with one of the cylinders and racks, the rack of the
ylinder F (a vertical section of which is shewn by Fig. 7) gears with a pinion E that
free on the pin of the second joint but can be clamped thereon. This pinion E has
ttached to it a bevil pinion H gearing with another bevil pinion K that is fixed to
he suspending frame B having its axis in line with the first joint as will be seen in
ig. 8 which is a sectional plan of the double joint. When the rack pinion E is free
n its pin, the movement of the rack turning it and its bevil pinion H causes the
tter to travel round the second stationary bevil pinion K thus swinging the machine

page_text: in the one vertical plane. When the rack pinion E is clamped on its pin, as owing to
the engagement of the bevil pinions H and K it cannot turn, the rack when it moves
has to travel round the then stationary pinion E, thus swinging the machine in the
other vertical plane. In both cases the suspending frame B, being hung by a swivel
or mounted on a vertical axis, can be turned round in the horizontal plane and can be
raised or lowered by a crane or otherwise, and thus the punching or rivetting machine
boing capable of angular adjustinent in the horizontal plane and in two vertical planes
at right angles to one another, besides being capable of being raised or lowered, can
have its operating tools directed in any desired line, the angular direction being
adjusted according as the valves of the two cylinders D, F of the apparatus shown in
Sheet I are manipulated, or according as the valves of the cylinder F and the clamping
or unclamping of the pinion E are worked in the modified apparatus shown in
Sheet II.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim in
respect of fluid pressure apparatus for adjusting portable rivetting and punching
machines to different attitudes, is :-
1. The construction and use of the apparatus substantially as described with
referenee to the figures on Sheet I.
2. The construction and use of the modified apparatus substantially as described
with reference to the figures on Sheet II.
