IMPROVE- MENTS IN HAND AND STEAM STEERING GEAR
Year: 1884

page_text: I, JOHN HENRY SMILES of 1, Carr Street, Stockton-on-Tees, in the county of
Durham, Engineer, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN HAND AND STEAM STEERING GEAR, to be as follows:-
The frame, triangular and box-like in form-may be cast in one piece,
dispensing with base-plate etc.
A crank shaft a is carried across, and through the upper part of the said frame.
The crank, eccentric etc. are inside the frame. A pinion is mounted on crank
shaft a, also within the frame, and is free to revolve on, or be carried round
with it.
Pinion is attached to a sleeve, which is supported in the frame, crank shaft a
passing through it.
A Hand Steering Wheel is mounted on the said sleeve, at the outside of the said
frame, and is free to revolve upon it.
A Clutch is attached to the said sleeve, at the opposite end to that of pinion b.
This Clutch has a given movement in or out of the sleeve, with which it is always
in gear.
When the clutch is drawn "outward," the sleeve is then geared with
crank shaft a, and is caused to revolve with it, but when moved "inwards," the
sleeve is dis-connected with crank shaft a, and connected with the steering wheel.
When in mid-position all three are connected. It will thus be seen, that the Clutch
is always in gear, for Hand, or power, or both.
Parallel, and on each side of Crank Shaft a, two counter Shafts c c, with two
small spur wheels dd, and pinions e (4) attached, are carried.
The small spur wheels d d. are on the inside of the frame, and gear with the
aforesaid pinion b.
Pinions e (4), are attached to each end of shafts c c and are on the outside of
the frame. They gear with two large spur wheels f. f. one on each side of the
frame.
These wheels f. f. are connected by means of a shaft g, which passes through
the central part of the frame. A chain wheel or barrel is attached to the said
shaft g. on the inside of the framing. It will be seen that the aforesaid pinion b,
acts upon the small spur wheels d. d., which carry motion by means of shafts c c,
to pinions e (4), these transmit it to large spur wheels ff., which convey it to
the chain barrel, through shaft g. Thus, constituting the Quarternary character of
the gear.

page_text: It will also be seen, that the gear may be made Duplex, by dispensing with one
of the large Spur Wheels f f., and two of the pinions e (4). In this case the small
spur wheels d d., and pinion b, may be brought outside the frame, and mounted on
the ends of their respective shafts. When a chain wheel is used, the aforesaid
pinions e (4) will gear internally in a large annular wheel or wheels.
The engines are of Diagonal type, the Cylinders being between the framing, at
opposite sides of Crank shaft a, and at right angles to each other.
One crank and eccentric suffices for the two cylinders. The Engines may be
Trunk, Oscillating, or ordinary.
In the case of Trunk and Oscillating, the Cylinders are supported between the
frame, but Cylinders of the Ordinary type of Engines overhang the frame.
The aforesaid eccentric, or valve motion for Steam Steering Gear, will be that of
my Patent of August 9th 1882. No. 3799.
In order to prevent the ringing sound, caused by the back-lash, the wheels arc
cast hollow and disc-like, the cores being left in, or the hollows filled with any
loose material.

be cast on the outside of the frame, and closed with a cover, or

the form of the wheels and pinions. The covers may have bearings formed in
them, to support the ends of the shafts.
Either modification-Quarternary or Duplex-may be used for Hand Gear only,
by replacing the crank shaft, by a plain shaft, with the necessary pinions attached.
Hand Steering Wheels_may_be_mounted_on_each,_or_at_both_ends of the aforesaid
shaft a.

page_text: I, JOHN HENRY SMILES of 1 Carr Street, Stockton-on-Tees, in the county of
Durham, Engineer, do hereby declare tlie nature of my invention for IMPROVE-
MENTS IN HAND & STEAM STEERING GEAR and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following.
statement:-
The frame-triangular and boxlike in form-may be cast in one piece, dispensing
with baseplate etc.
A crank shaft is carried across and through, the upper part of the said. frame.
The crank, eccentric etc, are inside the frame. A pinion is mounted on crank shaft,
also within the frame, and is free to revolve on, or be carried round with it.
Pinion is attached to a sleeve which is supported in the frame; crank shaft passing
through it.
A Hand Steering Wheel is mounted on the said sleeve, at the outside of the said
frame, and is free to revolve upon it..
A clutch is attached to the said sleeve,.at. the opposite end to that of pinion.
This clutch has a given movement in or out of the sleeve, with which it. is always.
in gear. When the clutch is drawn outward, the sleeve is then geared with crank
shaft, and is caused to revolve with it, but when moved inwards, the sleeve is
disconnected with crank shaft, and connected with the steering wheel, or vica verca,.
according to the arrangement of the clutch. It will be seen,. that the clutch: is:
always in gear for hand or power.
Parallel and on each side of Crank shaft two counter shafts, with two small spur
wheels and pinions attached, are carried.
The small spur wheels are on the inside or outside of the frame, and gear with
the aforesaid pinion.
Pinions are attached to each end of' shafts, and are on the outside of' the frame.
They gear with two large spur wheels, one on each side of the frame.
These wheels are connected by means of a shaft, which passes through the
central part of the frame.. A chain wheel or barrel is attached to the said shaft on
the inside of the framing.
It will be seen that the aforesaid pinion acts upon the small spur wheels, which
convey motion by means of shafts to pinions, these transmit it to large spur wheels,,
which convey it to the chain barrel, through shaft, thus. constituting the Quarternary
character of the gear.
It will also be seen, that the gear may be made Duplex, by dispensing with one
of the large spur wheels, and two of the pinions. In this case the small spur
wheels, and pinion may be brought outside the frame, and mounted on the ends of
their respective shafts, or pinion may be geared with the large spur wheel, and the
two counter shafts be dispensed with.

Similar letters in all figures, represent similar, or corresponding parts.
The crank shaft a is carried in the upper part of the framing. Pinion b is formed
on sleeve g through which crank shaft a passes. The boss of the Steering Wheel /
is carried on the end of sleeve g and is held in position by collar or ring 7. Clutch
block is keyed on, or otherwise, to the end of crank shaft a a groove is formed
across this block, to receive the clutch j. Clutch j is always geared with sleeve g,
along which it has a given movement, to gear with the aforesaid clutch block i, or
with the hand wheel h, which also has a groove or space to receive the same. The
aforesaid clutch j takes the form of a cross key. The handle or nob k, is for moving
the clutch along the sleeve, for hand or power, it is held in position by a radial
catch, on the boss of the wheel, which catch fits into grooves on the handle.
The large spur wheel gears with the aforesaid pinion b, and is mounted on
shaft n, upon which chain barrel or drum o is carried. Drum p is for leading the
chains to the aforesaid barrel o. The cover m encloses spur wheel f. The hole r
in the said spur wheel f is to facilitate the removal of bush q, which facilitates the
fixing or removal of the barrel o. The frame sides 8. Parts s' run from sido to
side of the frame, thus connecting the sides, and preventing grease from dropping
on to the deck. The whole forming an angular but bottomless box.
t. is the connecting rod, u the guide bars, the eccentric rod, and w the eccentric
sheave.
A concentric spindle may be carried along the centre of crank shaft a, and be
connected to the eccentric by a short arm, or in a similar manner to that of my 4
Patents of Augst 9th, 1882 No 3799 and Augst 28th 1884 No 11717, and my
application of Nov 18th 1884 No. 15133.
The said spindle would be connected in a suitable manner to nob k to facilitate
the working of the valves by hand Wheel h.
