I ARTHUR EDWIN SYMMONDS Keyworth Place Edward Street Balsall Heath
Birmingham Toolmaker do hereby declare the nature of this invention to be as
follows:-
This invention has for its object improvements in Machines or Machinery, to be
work by Manual or Steam Power to obtaine either fast or slow speed, A is the
Frame or Bearings for the Spindles to rotate in, J. is the Driving Spindle this.
spindle is hollow haveing been bored out, at the one end it is cut out four Square
longitudenal a short distence in; on the outside at one end the driving wheel D is
keyed on at the other end a large Pinion G is fit on, this Pinion G as bevelled teeth
upon it and a Ring of internal teeth within the Periphery, the spindle B is a smaller
spindle which passes through the spindle J, one end of spindle B is bored out and
a thread cut in, into this thread the ajusting Pin M is screwed in, by turning
this Pin or moveing a lever causes the spindle to move endwise, at the other end a
small Pinion E is keyed on, this Pinion as bevelled teeth upon it and a Ring of
external teeth round the Boss, the spindle C as double bearings in the Frame A,
this spindle as two small Pinions F and H fit upon it and are keyed on the spindle
with feather keys into the longitudenal slot N which is cut in, K is a piece of tube
fit on the spindle C and between the frame A and the Pinion F this keeps the Pinions
frome riseing, by means of the ajusting screw or a lever the Pinions are either one
or the other put into gear with a corresponding Pinion on the spindle C thereby
causeing a fast or slow motion.

Birmingham Toolmaker 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, and with reference to the Drawings filed with my
Provisional Specification :-
on.
This invention has for its objects improvements in Machines or Machinery to obtain
either fast or slow speed. A is the frame or bearings for the spindles to rotate in,
J is the driving spindle this spindle is hollow & four square inside longitudenal.
The driving wheel D is keyed on this spindle outside the bearing A. The large
Pinion G is fitted on the other end, this pinion has bevelled teeth upon it & a ring
of internal teeth within the Periphery L. The spindle B is a four square small
spindle and passes through the spindle J, one end of it B has a thread cut inside &
the ajusting Pin M is screwed into it, at the other end the small Pinion E is keyed
This Pinion has bevelled teeth upon it & a ring of external teeth round the
boss L. The spindle C has double bearings A and two small Pinions F & H are
fitted upon it & keyed on with feather keys into the longitudinal Slot N.- There is
a piece of tube K fitted on the spindle C between the Pinion F & the bearing A this
tube keeps the Pinions from rising. I is a small thumb Nut to turn the ajusting
Pin M with. When the fast speed is required turn the ajusting Pin M this will
cause the spindle B to move endwise the Small Pinion E with the ring of external
teeth round the Boss is now pulled into the internal teeth within the Periphery of the
large Pinion G when the Pinion E is within the Periphery of Pinion & it is
withdrawn out of Gear with its corresponding Pinion, F the Pinion E is now made
fast within the Pinion G & the two now rotate together G is geared with its
corresponding Pinion H causing the fast speed. When the slow speed is required
slack out the ajusting Pin M the Spindle B will move endwise the Pinion E is freed
from the Pinion G & put into gear with the corresponding Pinion F causing the
slow speed. When the slow speed is in gear the large Pinion G is rotating freely on
the Spindle J.
Having now particularly described & ascertained the nature of my said Inven-
tion & in what manner the same is to be performed, I declare that what I
claim is.
1st. That the Gear is injenious in movement & design.
2nd. That it will meet a want long felt by the trade for Drilling Machines &
Machines that work with Shafts or Spindles at right angle.
3rd. The construction and arrangements of the Gear and for the purpose herein-
before described and shown on the Drawing.
