PROVISIONAL SPECIFICATION.
Improved Method for Driving Multiple Spindles or Shafts, such as
those used in Drilling Holes in Wood or Iron, or for Ropemaking,
Cotton Spinning, Turning in Cartridges, Twin Screw Propulsion,
Multiple Spindle Lathes, or other Machines where a number of
Spindles or Shafts are used.
We, CHARLES WALTER Vosper, Sewing Machine Engineer, of 5 Woodland
Terrace, Ashleigh Road, Barnstaple, and WILLIAM CLAUDE RAFAREL, Engineer
of "The Foundry," Barnstaple, both in the County of Devon, do hereby declare the
nature of this invention to be as follows:-
According to our invention, we adopt an ordinary frame similar to that now in
use for driving multiple spindles or shafts, such as those used in drilling holes in
wood or iron, or for ropemaking, cotton spinning, turning in cartridges, twin screw
propulsion, multiple spindle lathes, or other machines where a number of spindles
or shafts are used but instead of using belts, pullies, and cog wheels, we use cranks
which are so arranged that any number of spindles can be turned in one frame, all
of which would be driven from one main shaft, the spindles or shafts turning in one
direction and at the same speed.
In order to effect this movement, each spindle or shaft when in its place in the
frame will be provided with a bevelled crank, the ends of which will be inserted
into a disc, or connecting plate provided with a number of holes corresponding with
the number of spindles used in the machine. A. half crank is fixed to the main, or
driving shaft, and is also inserted into the same disc or connecting plate in a
separate hole out of the centre line but parallel to the spindles and on the opposite
side to where the bevelled cranks are inserted. By this means any number of
spindles can be made to work, so that all the holes in the head of a brush could be
bored at one time, or a hundred or more cartridges turned in at one operation, or
all the spindles in a cotton spinning frame be driven with perfect certainty of speed,
each spindle performing the same number of revolutions. A thing impossible where
only belts and pullies are used.

Improved Method for Driving Multiple Spindles or Shafts, such as

Cotton Spinning, Turning in Cartridges, Twin Screw Propulsion,
Multiple Spindle Lathes, or other Machines where a number of
Spindles or Shafts, are used.
We CHARLES WALTER VOSPER, Sewing Machine Engineer, of 5 Woodland
Terrace, Ashleigh Road, Barnstaple and WILLIAM CLAUDE RAFAREL, Engineer,
of "The Foundry," Barnstaple both in the County of Devon, 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 :-
This invention relates to improved method for driving multiple spindles or
shafts such as those used in drilling holes in. wood or iron or for. ropemaking,

page_text: cotton spinning, turning in cartridges, twin screw propulsion, multiple spindle
lathes, or other machines where a number of spindles or shafts are used.
Instead of employing belts, pulleys and cog wheels we use bevil cranks so
arranged in their frame plates that any number of spindles can be turned at one
time, all of which turn in one direction and at the same speed.
In order to effect this movement each spindle or shaft when in its place in the
frame is provided with a bevilled crank, the ends of which are inserted into a disc
or connecting plate provided with a number of holes corresponding with the
number of spindles used in the machine. A half crank is fixed to the main or
driving shaft and is also inserted into the same disc or connecting plate in a
separate hole out of the centre line but parallel to the spindle and on the opposite
side to where the bevilled cranks are inserted. By this means supposing the
required number of tools be fitted in position all the holes could be made in the
head stock of a brush at one time, or a hundred or more cartridges could be turned
in at one operation, or all the spindles in a cotton spinning frame might be driven
with perfect certainty of speed, each spindle performing the same number of
revolutions, a thing impossible where only belts and pulleys are used.
Our invention will be understood by the annexed drawings.
Figure 1 represents the side elevation of an apparatus suitable for turning the
ends of shot cartridges, in upon their wads.
Figure 2 is the front elevation of same.
Figure 3 is a part section of the cranks and other parts to indicate the method of
working them in close proximity.
It is proposed that any number of spindles can be used by our invention in the
same machine from one to a hundred these are so placed that each one works at
the same speed.
The frame we employ is very similar to that of a drilling machine. In this
frame A are placed the driving gear, pulleys etc. the first pulley C is placed on a
horizontal shaft D near the base of the frame this shaft passes through the outer
part of it and into a hollow made for the purpose of carrying a fast and loose
pulley E, E. In a perpendicular line above this and nearly at the top is another
horizontal shaft F on which are placed two other pullies G, G, and at the other
end a bevilled gear wheel H in gear with another wheel H¹, this wheel H' drives a
vertical shaft I which is connected with the disc or crank J.
Near to the outer edge of the disc J is placed a crank pin see A¹ Figure 3 this
crank pin is in the crank plate K.
On the opposite side to this are a number of cranks L, L, having bevilled stems
in order to pass each other; These bevilled cranks are secured to a series of
vertical spindles M. M which pass through a projection of the frame A and are
then attached to chucks S, S, or other necessary appliances for turning in cart-
ridges, or tools for drilling holes.
Under these chucks S, S, is placed the table B hung on two pillars N. N
inserted into the frame A which can be lowered and raised by a screw P worked
by a hand wheel Q and gear wheels R, R.
The cartridges are placed on the table in a frame suitably made to meet the
chucks, the bottom ends of the cartridges fit into chamfered holes either in the
frame in which they are filled, or in the table, or in a plate made for that purpose
according to requirements. The chamfered holes will be made in the same way as
they are now, the only difference being that there will be a very large number of
them, the grip to prevent them from turning round being the same then as now.
In Figure 3 we show in section eccentric pins T, T, placed in the position shown
to take up and prevent friction and can be used for all purposes to which bevilled
cranks as herein described are used.
The object of the eccentric pin is to prevent a tightness from occuring in cases
where the cranks may not be made exactly the same length. There is a large
number and they have to be made exceedingly accurate in order to pass each other,
and unless the deviating pin is used, they cannot be driven at a great speed.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. A machine with multiple spindles turned by bevilled cranks substantially as
described with reference to Figures 1 and 2 of the annexed drawings.
2. The employment of multiple spindles having bevilled or other cranks with
eccentric pins as shewn at Figure 3 when used for any purpose for which bevilled
cranks or multiple spindles can be applied substantially as herein described.
