page_text: LETTERS PATENT to William Carter, of Sneinton, in the County of Not-
tingham, for the Invention of "IMPROVEMENTS IN STEAM CULTIVATING
APPARATUS."
Sealed the 15th November 1878, and dated the 5th September 1878.
PROVISIONAL SPECIFICATION left by the said William Carter at the Office
of the Commissioners of Patents on the 5th September 1878.
WILLIAM CARTER, of Sneinton, in the County of Nottingham.
IN STEAM CULTIVATING APPARATUS."
"IMPROVEMENTS
I employ two traction engines of the usual construction, but in addition thereto
I provide each engine with a framing, upon or under which two or moro rope
guiding wheels aro capable of adjustment, so as to afford space for the implements
employed to pass each other.
Each engine is provided with two or more winding drums, each of which carry a
toothed wheel capable of being driven by a spur wheel gearing into it.
Either or
the whole of the spur wheels are made capable of being thrown into or out of gear
with the toothed wheels by means of hand levers. The spur wheels slide upon a
koy carried by or forming part of a shaft driven by the engine.
There are two or more steel wire ropes; one end of each rope is attached to one
of the winding drums of one engine, and the other end may be attached to one of
the winding drums of the other engine; and intermediately of the length of each
rope, or near one end of each rope, one or more ploughs, drags, harrows, drills, or other
implements are attached, and when requisite I employ one or more rope porters to
each rope. By such means I am enabled to employ two or more sets of implements
running the same or the reverso way to each other at the same time, with a direct
pull upon each implement, and thus effect a considerable saving of time.

DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view of the hinder part of a traction engine with portion of 2
my improved apparatus applied thereto; Figure 2 is a plan of the same.
.
Figure 3 shows in plan portions of the apparatus connecting the rear end of the
traction engine with the front end of a winding drum frame hereafter mentioned;
and Figure 4 shows a side view of such frame end and connections.
In the Drawings the toothed wheels hereafter referred to are in outline only, the 3
teeth are not shewn.
The several corresponding parts in each Figure are lettered alike.
In carrying out my improvements, for the sake of illustration, 1 have shewn my
apparatus in the Drawings as applied to a traction engine of the usual construction
provided with a single steam cylinder and carrying a rope-winding drum on the 3
under side of the boiler, portion of such drum A being seen in side view at Figure 1
to the casting B which carries or forms bearings for the upper end of a vertical
shaft C' and an inclined shaft D. The lower end of the shaft C¹ revolves in a
bearing in a bar C bolted to the bracket C. The vertical shaft carries a key upon
which a double toothed wheel slides; this wheel has teeth upon its lower and 4
upper sides, and when lowered into the position shewn at Figure 1 by a link
connecting it to a hand lever C, its lower teeth gear into the teeth of a wheel C
which slides upon a key carried by the driving shaft B. When the wheel C³ is
thrown out of gear with a toothed wheel C, secured on the upper end of a vertical
shaft, which carries a toothed pinion at its lower end, which drives the rope drum A, 4
the wheel C³ is shewn out of gear with the wheel C in Figure 2, being moved by
the usual hand lover, not shewn in the Drawings. When the toothed wheel C³ is in
the lower position, a toothed wheel D' sliding on a key carried by the shaft D can
be thrown into gear with its upper teeth by means of a link connecting it to a hand
lever D. The lower end of the shaft D revolves in a bearing D³ secured to the 5
back of the engine. The shaft D is provided with two collars between the bracket C
and bearing D³ to secure it in position.

page_text: By means of the toothed gearing above described, when the engine is at rest and
not in gear with the rope drum beneath the boiler, I can obtain independent
revolutions of the shaft D for the purpose hereafter mentioned.
When a traction engine is employed similar to the above described, carrying one
winding drum, I provide each such engine. with a rope winding drum E partly
shewn at Figures 3 and 4. The drum and winding gear is of the usual construction,
but the driving shaft E' is driven by the engine by the following means:-The
winding drum E revolves upon a framing E' carried by two wheels E. On the front
end of the framing is bolted the standards carrying the usual driving shaft E'; when
two drums are employed such standards are bolted on the framing intermediately
of the drums. Below the horizontal bevel wheel of the drum gearing I place a
tie bar E, each end of which I bolt to one of the standards. The tie bar supports
a bracket bearing E' in which a short shaft revolves; a toothed bevel wheel E is
secured on the lower end of the shaft and gears into a similar wheel E7 on the
driving shaft E' above the bearing Es. The shaft is provided with a collar to keep
it in position, and above the collar the shaft is formed square, sliding in a square
hole in the lower end of a donble knuckle joint E secured on the lower end of the
driving shaft D, thus forming a true connection adjustable in the direction of its
length.
The front end of the drum framing carries a socket F in which the shaft F
slides. The socket has a hole through it noar its front end through which is passed
a bolt F which slides through a bracket F³ carried by the socket between the
bracket and the socket; the bolt is provided with an adjustable collar. The
upper end of the bolt is connected by a link to the outer end of a hand lever F*
which can be operated by an attendant on the engine. The collar on the bolt
prevents the entire withdrawal of the bolt from the socket, yet allows the bolt to.
be raised clear of the holes in the shaft F¹ which are shewn by dotted lines
in Figure 1, such arrangement enabling the attendant to move the engine
further from the drum without entirely breaking the connection excepting when
requisite.
The shaft F is hinged to a bracket bolted to the back end of the engine. But I
do not confine myself to a connection arranged as above described, as may some-
times prefer to hinge the socket to the back of the engine and secure the shaft to
the drum frame as most convenient.
I also employ two draw chains G (shewn only in plan at Figure 3) to prevent
the engine drawing away from the drum frame when at work.
When double winding drums are employed behind the engine I connect a rod to
the starting lover of the druin, gearing in such a way that it can be operated by
the attendant on the engine. And to counteract the side strain of the rope upon the
drum frame I employ two stays or bars H and J, one on each side of the drum
frame, the back ends of each of which are hinged and turn upon an axle pin
secured in the drum driving shaft standard. The stay H is supported by a bracket
arm I secured to the engine; the front end of this stay is forked and clips the right
carrying wheel of the engine, and when in the position shewn in Figure 3 is firmly
wedged between such wheel and the rope drum frame. This stay is clipped by tho
outer forked end of a lever which can be raised by a hand lever I', thus enabling
the attendant on the engine to lift the stay quite clear of the carrying wheel when
required. And to further resist the side strain of the rope I form the front end of the
stay J of such a shape that it will, when in the position shewn at Figure 3, firmly
hook on the outer edge of the left carrying wheel of the engine. The stay slides upon
a hinged bracket arin K secured to tho engine, and is connected by a link to the axle
of a rocking hand lover K', the front end of the stay being thrown clear of the
wheel upon the attendant pulling the hand lever K' towards him. I construct the
stay J in two lengths, and reversely screw-thread the inner ends and join them by
a reversely screw-threaded socket J, by which means I can adjust the length of the
stay to the length required by simply turning the socket with wrench.
The rope guiding wheels I employ are not shown in the Drawings, being of the

page_text: usual construction but arranged so that I can adjust them where required, so as to
afford space for the implements employed to pass cach other; or I employ guiding
wheels upon double drum engines carried by a bracket of the shape shown at
Figure 44.
Each winding drum is provided with a steel wire rope. One end of each rope is
attached to one of the winding drums of one engine, and the other end may
be attached to one of the winding drums of another engine, and intermediately of
the length of each rope, or near one end of each rope one or more ploughs, drags,
drills, or other implements are attached; and when requisito I employ one or more
rope porters to each rope. By such means I am onabled to employ two or more
sets of implements running the same or the reverse way to each other at the same
time, with a direct pull upon each implement, and thus effect a considerable saving
of time.
I would have it understood that I do not confine myself to the arrangement
shewn at Figure I for operating the driving shaft D, as the connection of the said
shaft will vary in position according to the construction of the traction engine
employed.
When the engines are working in pairs the stays H and J, and the rope guiding
wheels, rope winding drums, and coiling gear are reversely placed with respect to
each other.
In witness whereof, I, the said William Carter, have hereunto set my hand
and seal, this Twenty-sixth day of February, in the year of our Lord One
thousand eight hundred and seventy-nine.
