THE tROWCAL AQRtCULTURiaT, 
[March i, 1892 
separately it would record it only in riKht lines; whereas 
if each in the other machine recorded its motion on a 
separate piece of paper it would record it in circular 
or eccentnc lines. That wa.s the truer way to put 
the difforeut characteristics of the two machines before 
the Court. Mr. Jackson wont all that way round to get 
a circular result, or, should he say, all the way square 
to get a circular result. To affect that mechanism, he 
thought it had been abundantly shown, every pai-tmust 
be attached and in operation — that one pari would not 
work withont the other. It liad been repeatedly shown 
in Mr. Jackson's own machine that if that upper part 
were removed aud an attempt made to move the 
machine, it would do one of two tilings ; it would 
either got into a position in which the crank would 
run round without doing anything at all or it would 
got into a more jammed position in which the crank 
would not move at all. This he proceeded to illustrate by 
a model the inventor of the' triple-action roller liad made, 
contending that in order to make the whole machine 
work harmoniously there must be a connecting rod. 
It mattered not whether the connecting rod was a 
rod of greater or lessor thickness, square, oblong, or 
anything else, so long as it made tlio connection 
between the one point and the other — between the 
sliding bar and the crank pin. Mr. Jackson’s machine 
required that principle of the connecting rod, and 
when Mr. Jaekson went into the witness-box and 
practically asked the Court to believe tliat this upper 
metal frame aud the wooden box that holds the lea 
was the jacket and nothing hut a jacket, aud was 
not part of the driving mechanism, he was contra- 
dicted by his models, by all experience and by liis 
own witnesses. Ooiinsel then referred to Mr. Jackson's 
evidence on this point to show, as he put it, how 
completely Mr. .Tackson had given himself away, 
directing the .fudge’s attention in passing to the 
circumstance of how often Mr. .Jackson'aiiswerod “Yes " 
or “ No;" iiow often he began liis answers by " I must 
explain ;” how often he gave them as it were a small 
lecture on a inecbsJiical point, aud in the end saying 
he could give no answer at all. If tliero was an- 
other thing which would tend to discoimt Mr. Jackson 
as an oxiioii he submitted moat emphatically it 
would bo the way he had evaded liis questions. Ho 
thought he had two “yeses” and ono “no” from him in 
five hotus’ examination. He tackled Mr. Jackson 
three times on the question of tlio upper rolling 
surface being a connecting rod aud a part of the 
driving niecJjanism, and the Judge would see 
on reading the evidence liow he went from had to 
worse and in the end actually said it was not a driving 
mechanisiu hut a thing driven. Counsel quoted 
several passagoa iu plaintiff’s evidence, and subse- 
quontly alluding to tlio deposition of Mr. Lamont 
confessed he was surprised to find that gentieman 
agreeing with Mr. Jackson, adding in the concluding 
paiti of nis reference to Uiis witness’s statements tlmt 
Mr. Laiivuiit's answers were each a refutation 
of his assertion. Mr. Ijamont said the jacket drove 
the cap but was not a part of the driving 
mcchauisni. Ho said he could not drive it 
without it and yet that it was not part of the 
driving meohauism. Surely it must be so. Tliey 
wanlod the driving mechanism to drive every part of 
the machiujo, and if they could not do it without this 
part surely it must be part of the driving mecha- 
nism. The other witnesses had gradually progressed 
for, BO far as his memory served, they had admitted 
this principle. The fact of the matter was that this 
machine not only resolves circular into rectilinear 
motion but, if it might be so called suppressed 
circular motion. Naturally the cranks in moving 
would have a tendency to engender circular motion 
aud where the guide opposite was of a corresponding 
nature circular motion resulted, but when tlie guide 
was made rectilinear — aud this guide was made 
rectilinear — aud the form of tlie crank was slightly | 
altered oirculiu’ motion was suppressod into rcctilli- ; 
near. The crank pin that seemed to be going round j 
was really moving nackwards and forwards in straiglit j 
lines. Even MaGuire showed how the guide operated 
to make Jackson’s machine work in a rectilinear 
motion. Hutson advanced the position mueli further 
ftnU Uiowu ovou further still. Ho next quoted from 
Raiikine’s applied mechanics the definition of what 
was called link work to the effect that the pieces 
which are connected by link work if they rotate or 
oscillate are shortly named crank beams or levers. 
The link by which tliey are connected is a rigid bar 
whicli may be straight or any otlior figure. The 
straight figure being the moat favourable to sti-engtli 
is used wnen there is no special reason to the 
contrary. The link is knovra by various names under 
various cirouuiatancos, such as coupling rod, connecting 
rod, crank rod, eccentric rod, Ac. It is attached to 
the pieces wliich it connects liy two pins about 
which it is free to turn. Now he argued that 
what Mr. Jackson culled liis jacket was not a true 
jacket, and that the metal work of it was a con- 
necting rod in the driving mechanism of his machine. 
Jackson knew what was coming ; lie had known of 
it all along in this case ; ho liad known that it was 
open to the defendants to take their power off tlie 
driving mechanism. He might divert the driving 
mechanism into as many streams as he Uked, and 
that was the reason J ackson would not admit it. 
Jackson liad gone so far as to do that which his 
witnesses had contradicted — to assort that it was 
driven and not driving mechanism. He wanted to 
talio it out of the driving mechanism of his macliine, 
for ho knew what was before him, and for thotliird 
time when he pressed him Jackson actually 
jumped over the precipice aud said it was driven 
mechanism alone. Jackson said that the jacket part 
in the Excelsior was tlio last part of his machine 
directly moved by the driving mechanism and its 
office was to keeii “ A ” (the upper rolling surface) 
iu position and carry it with it. Was that its only 
office Well suppose they took it off would the rest 
of his machine go ? Oh, he said, he could not tell. 
He was like one of those musicians who could only 
compoBO a piece of music with the keys of the piano 
before him and gradually stumliled into the proper 
chord and harmony. lie could not take a sbuot of 
foolscap and sitting down under the shade of a green 
tree there write down chorda of perfect harmony that 
no mortal oar had ever hoard. He was only a 
practical man and was in the position of Mr. Brown 
of the Railway who thought the thing would go 
until he took tho machine to pieces and found it 
would not go. Mr. Jackson’s invention was notonly 
a roundabout way of getting circular motion ; ft 
resolved circular motion into its component parts 
and brouglit tluiui together ; hut it was mechanism 
throughout and tlie jacket was part of the me- 
chanism, and a material part. Mr. Jackson might 
deny that, but it was patent to the eyes, 
patent by the evidence, and patent by Jackson’s speci- 
fication. Did Jackson in his specification claim tho 
link or connecting rod of metal as part of his jacket ? 
He never did. The lettering on the drawing showed 
this ; he snbmitted tliat it did not lend anyone to sup- 
pose or imagine that when Jackson spoke of the case 
or jacket loosely surrounding tho upper rolling surface 
he meant the metal work. The spocifioation was silent 
about that, and the reason was that it was the connect- 
ing rod, a neoessary part of the mechanism which 
it was nnuocossory to describe because it was as 
inevitable that there must bo a connection between 
tho two points as it was tliat the sun would shine 
that there be day. The lettering was done entirely 
on the upper part— on the actual container cf the tea 
leaf and the immediate surface surrounding tlie upper- 
rolling surface, — and therefore Jackson’s specificaiion 
did not warrant the inference ho deduced from it, but 
on the contrary, taken in conjunction with their 
reasoning applied to it, with tho principles of me- 
chanics, and with the evidence of the expert witnossos, 
showed tliat tho metal work was not part of the jacket 
but had the function of a connecting rod. 
The JnnuE: — (.'an’t it be both? 
Mr. RiiowNii: — Rossihl)-; as a connecting rod it is 
utilized to carry the top surface ; but even if it had a 
double function, ono of its functions was to act as part 
of the ordinary driving meclianism, namely a oounect- 
iiig rod for which he had taken out no patent and 
which it was perfectly open to the defendant to 
utilise in the way ho had done. Mr. Jackson said 
1 ho wanted to get something light in weight and
