PROVISIONAL SPECIFICATION.
Improvements in Pile-driving, Stamping, and like Machinery.
I, FREDERICK JOHN ROWAN, of 121, West Regent Street, in the County of
Glasgow, North Britain, Engineer, do hereby declare the nature of this invention
to be as follows, that is to say :-
My said invention comprises combinations and arrangements of parts of pile-
driving, stamping, and like machinery, enabling electricity to be satisfactorily
applied as the motive agent.
In one modification of my improved machinery a frame, which is fitted to slide
vertically between guides, is suspended by a chain passing up to and around a
pulley and thence down to a winch by means of which the frame can be adjusted
at any desired height on the main framing. A dynamo or electric motor is
mounted on the frame, and a worm on its shaft gears with a wormwheel on a
horizontal shaft which by spurwheels drives a parallel horizontal shaft. These
two shafts have on them pulleys between which there is a long vertical lifting
bar of wood or other suitable material, having the monkey or heavy pile-driving
block attached to its lower end. One of the two pulley shafts has one of its
bearings in an eccentric bush to which a lever is fixed, and by moving which the
shaft moves its pulley nearer to the other pulley so as to grip the lifting bar, or
further from it so as to let go the lifting bar. To the lever of the eccentric bush
there is jointed a rod extending downwards and having on it two tappets, arranged
to be acted on by a kicker on the monkey. The pulleys rotate continuously in a
direction to raise the lifting bar and monkey when they grip the bar; and on the
monkey approaching the top of its lift the kicker on it strikes the upper tappet on
the rod connected to the eccentric bush and causes the separation of the pulleys
and the dropping of the monkey. On the descent of the monkey its kicker strikes
the lower tappet and causes the pulleys to again grip the lifting bar and raise the
monkey. The gearing between the dynamo shaft and pulley shafts may be varied
in different cases.
The lever of the eccentric bush may be moved by hand when
convenient as for example when working with a short stroke.
In a second modification the pulleys are made of a size such that a part of the
circumference is equal to the lifting stroke, such part of each pulley being of a
diameter which will make the pulleys grip the lifting bar, whilst the other parts
are of less diameter. As the pulleys rotate continuously, their more projecting
parts will grip and raise the lifting parts, whilst their less projecting parts will
allow the monkey to drop.
In a third modification a screw spindle is substituted for the lifting bar and is
acted on by a bush or box driven by the dynamo and fitted with internally screwed
segments adapted to engage with the screw spindle. The screwed segments may
be moved into and out of their engaging positions by kicker and tappet mechanism,
or by means of electro-magnets put into and out of action by means of electrical
contacts or switches operated from the up and down movements of the monkey.
In the cases of stamping and like machinery the framing and other parts may be
suitably modified and the frame carrying the dynamo, the gearing and the gripping
pulleys may be stationary or adjustable as required in each case.

page_text: Improvements in Pile-driving, Stamping, and like Machinery.
I, FREDERICK JOHN ROWAN, of 121, West, Regent Street, in the County of
Glasgow, North Britain, Engineer, do hereby declare the nature of this 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 :-
My said invention comprises combinations and arrangements of parts of pile-
driving, stamping, and like machinery, enabling electricity to be satisfactorily
applied as the motive agent.
Machinery as made according to my invention is shown on two accompanying
sheets of explanatory drawings,
Figures, 1, and 2, on Sheet 1, thereof being partial elevations, as at right angles
to each other, of one modification.
Figures, 3, and 4, on Sheet, 2, are elevations as at right angles to each other,
showing a second modification of some parts.
Figures, 5, and 6, are respectively a plan and an elevation showing a third
modification of some parts.
Figure, 7, is a plan of certain details of the third modification, drawn to a larger
scale.
In these drawings the same reference letters and numerals are used to mark the
same or like parts wherever they are repeated.
In the modification of my improved machinery shown in Figures, 1, and 2, of the
drawings a frame, A, which is fitted to slide vertically between guides, B, is
suspended by a chain, C, passing up to and around a pulley, D, and thence down
to a winch (not shown) by means of which the frame can be adjusted at any
desired height on the main framing, E. A dynamo or electric motor, F, is
mounted on the frame, A, and a worm, G, on its shaft, H, gears with a worm-
wheel, J, on a horizontal shaft, K, which by spurwheels, L, and M, drives a
parallel horizontal shaft, N. These two shafts, K, and N, have on them
pulleys, P, and Q, between which there is a long vertical lifting bar, R, of wood
or other suitable material, having the monkey or heavy pile-driving block, S,
attached to its lower end. One, Ñ, of the two pulley shafts has one of its bearings
in an eccentric bush, T, to which a lever, T 1, is fixed, and by moving which the
shaft moves its pulley, Q, nearer to the other pulley, P, so as to grip the lifting
bar, R, or further from it so as to let go the lifting bar. To the lever, T 1, of the
eccentric bush, T, there is jointed a rod, T 2, extending downwards and having on
it two tappets, T3, and T4, arranged to be acted on by a kicker, S1, on the
monkey, S. The pulleys, P, and Q, rotate continuously in a direction to raise the
lifting bar, R, and monkey, S, when they grip the bar; and on the monkey, S,
approaching the top of its lift the kicker, S1, on it strikes the upper tappet, T 3,
on the rod, T2, connected to the eccentric bush, T, and causes the separation of
the pulleys, P, and Q, and the dropping of the monkey, S. On the descent of the
monkey, S, its kicker, S 1, strikes the lower tappet, T4, and causes the pulleys, P,
and Q, to again grip the lifting bar, R, and raise the monkey, S. The gearing
between the dynamo shaft, H, and the pulley shafts, K, and N, may be varied in
different cases. The lever, T 1, of the eccentric bush, T, may be moved by hand
when convenient as for example when working with a short stroke.
In the modification of my improved machinery shown in Figures, 3, and 4, the
pulleys, P, and Q, are made of a size such that a part, P 1, Q 1, of the circum-
ference is equal to the lifting stroke, such part of each pulley being of a diameter
which will make the pulleys grip the lifting bar, R, whilst the other parts P2, Q2,
are of less diameter." As the pulleys, P, and Q, rotate continuously their more
projecting parts, P 1, Q 1, will grip and raise the lifting bar, R, whilst on

page_text: their less projecting parts, P 2, Q 2, coming round they will allow the monkey (S)
to drop.
In the modification of my improved machinery shown in Figures, 5, 6, and 7,
a screw spindle, V, is substituted for the lifting bar, R, and is acted on by a bush
or box, V 1, driven by the dynamo, F, and fitted with internally screwed
segments, V 2, adapted to engage with the screw spindle. The screwed
segments, V 2, may be moved into and out of their engaging positions by kicker
and tappet mechanism but they are preferably moved by means of electro-
magnets, V 3, put into and out of action by means of electrical contacts or
switches, V 4, V 5, and V 6, operated from the up and down movements of the
monkey (S).
In the cases of stamping and like machinery the framing, E, and other parts
may be suitably modified, and the frame (A.) carrying the dynamo (F) the
gearing (L, and M) and the gripping pulleys (P, and Q) may be stationary or
adjustable as required in each case.
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.
1. In pile-driving, stamping, and like machinery raising and releasing the
driving or stamping block by means of mechanism actuated by electricity and
such, substantially as is herein before described.
2. The combination and arrangement of parts constituting the improved
electrically-actuated pile-driving, stamping, and like machinery substantially as
herein before described with reference to Figures, 1, and 2, of the accompanying
drawings.
3. The combination and arrangement of parts constituting the improved
electrically-actuated pile-driving, stamping, and like machinery substantially as
herein before described with reference to Figures, 3, and 4, of the accompanying
drawings.
4. The combination and arrangement of parts constituting the improved
electrically-actuated pile-driving, stamping, and like machinery substantially as
hereinbefore described with reference to Figures, 5, 6, and 7, of the accompanying
drawings.
