MICHAEL ANDERSON Repairing Engineer Constantinople present address-
30 Whitby Street North Shields Northumberland, do hereby declare the nature of
this invention to be as follows:-
This invention is intended to repair Fractured Crank Shafts at sea, in less than
one fourth the time occupied with the tools at present in use. The use of the turned
ring as guide to the cutters, instead of through boring bar permitting both sides to
be operated on at the same time & securing a solid cut & straight hole to receive the
steel pin that will accompany each Machine. It can be worked by steam, by hand
winch, & with exellent effect by hand, drilling & boring proceed at the same time.
With this invention you have a continual cut instead of the intermittent cut of the
Ratchet Brace. As it can be worked in the most boisterous weather, it will supplant
the spare Crank Shaft.
.
I claim for this Machine that with the pinions being carried independently on the
plate between the two wheels; I can transfer the power from one to the other in a
few seconds. When speed is required place the key in the small wheel and work the
large wheel loose on the spindle, you obtain two turns for one. With the key trans-
fered to the large wheel, you have more power but slower.
Again when more power is required work the small wheel loose on the spindle when
you obtain double power.
Again when very heave work is to be done work all the handles in both wheels
when you obtain the original power-with double power added the large wheel
turning one way and the small one the other.
The wheels are connected or disconnected in a few seconds by a ring and screw on
the spindle at the side of each wheel.
These wheels are provided with grooves, so that steam power may be applied where
possible or a hand winch may be set up to drive it, when neither of these methods can
be applied it can be worked with powerful effect by hand.
The centre plate which holds the pinions is made with a handle to suspend the
machine in any position, the said handle to be fixed when double gear is being used.

page_text: The spindle is round with a flat side-on which the wheels slide At one end is a screw,
for feeding, at the other end is a hole to, fix the drills-with a cross hole for the
cutters. The end of the spindle is grooved for escape of the cuttings from the drill-
so that a very short drill may be used. The hole made by the drill admits the end of
the spindle, which is the first guide for the cross cutter, turned rings will be supplied
to act as guides to the following cut insuring a solid cut throughout.
With this machine no through boring bar is required the turned ring being quite
effective in keeping the hole true, and thus permitting both sides to be worked at the
same time.
I claim that with the second power wheel, this machine can be worked with
excellent effect between the cranks without coming in contact with the shaft, making
it immaterial which crank is to be repaired.
I claim that with this machine you can proceed to effect repairs at once, no
matter how bad the weather may be.
The time gained by the use of a ring as guide, in having a solid cut throughout.
The increased steadiness of the cut. Getting at both sides of the crank at once.
Drilling and boring at the same time with one machine Added to this the continual
cut preserves the cutters, thus fairly justifying my claim, to do the work with this
machine in less than one fourth the time it takes with the tools now in use..
The different powers contained in the multiplying gear, making it a really powerful
drilling and boring machine in a small compass and easily moved.

page_text: MICHAEL ANDERSON, repairing engineer, 30 Whitby Street, North Shields
Northumberland, 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:-
The chief object of this invention is to repair fractured crank shafts at sea in the
shortest possible time.
I can with this machine repair any size up to 200 H.P.N. in from twenty four to
thirty hours in any weather.
With the tools now in use, it takes from six to ten days to repair one, in point of
fact they are not often done at sea it takes so long to do it, that it is usual to take the
first steamer that comes in sight and tow to where it can be repaired.
With this machine it could have been done in twenty four hours, and the steamer
could have proceeded on her voyage.
With this machine I can operate on both sides of the crank at the same time, turned
rings are used as guides, thus securing a solid cut right through and at the same time
insuring a perfectly straight hole to receive the steel pin.
This machine is arranged for steam power, or for hand winch, and where neither of
these methods can be applied it can be worked with excellent effect by hand.
The driving wheels slide on the bar so that it can be used in a small space and
always remains in front of the winch for a fair lead.
I can through the pinions being carried independently on the centre plate, transfer
the
power from the small wheel to the large one in ten seconds.
When drilling small holes, place the key in the small wheel, having the handle in
the large wheel you obtain two turns of the drill for one of the large wheel.
When you are boring large holes transfer the key from the small to the large wheel
and you gain immense power.
The wheels can be connected or disconnected in a few seconds, by a ring and screw
at the side of each wheel.
This machine can be worked with good effect between the cranks, without coming
in contact with the shaft, there being a joint in the handles for that purpose, making
it immaterial which crank was to be operated on.
With this machine as soon as the drilling has proceeded sufficiently to admit the
end of the bar, which is the first guide, both drilling and knifing go on at the same
time.
The immense advantage gained by having a ring in front of the cutter for guide, in
having a solid cut throughout, the increased steadiness of the cut, getting at both
sides of the crank at the same time, drilling and knifing at the same time.

page_text: Firstly the spindle, A is of steel cast hollow with a hole at each end, one for the
adjusting screw B the other for the drill C, also a cross hole for the knife .D, this
spindle is about three feet long, with a flat side about one inch wide from end to end
for keys of wheels.
Secondly, the large wheel E, it is sixteen inches diam., with a groove F on the
outside for driving band G, and is cogged round the inner side for the pinions H, it
is 1 in. thick, there are four holes J for handles.
Thirdly the small wheel K, it is nine inches diam., grooved on the outside for wheel
band, it is cogged on the outer side, there are holes L to receive four handles M.
Fourthly the centre plate N, it is made in the form of a cross, and carries the four
pinions H on each side, these pinions are connected in pairs by a small spindle that
has its bearing in the centre plate.
This centre plate can be fixed by its arms in any position, and can be connected in
a few seconds by a skeleton frame and bolts.
Fifthly, the connecting pieces are two rings
wheels.
with set bolts at each side of
Lastly, the bandles, they have a hinge joint P to pass the shaft when the space is
insufficient.
The end of the spindle A at drill end is turned to the exact diameter of the hole
made by drill into which it enters and forms a steady guide for the knife.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is:
1st. The toothed wheels of different diameters gearing with double pinions by
means of which the speed and power can be changed as required in a few seconds by
changing the key from one wheel to the other substantially as described and shewn.
2nd. Instead of a through boring bar making the end of the drill spindle act as a
guide for the knife following the drill so as to drill and bore from both sides of the
crank at same time substantially as described and shewn."
