NEW PATENTS LATELY ENROLLED. 
MR. SIMEON TIHOMPSON’S (MADDOX- what might as readily be done by two, 
STREET, LONDON), for a new Method 
of raising Weights. 
HIS invention does not extend to 
very heavy weights, but is con- 
fined to those which are equal to, or 
rather less, than the weight of the man 
ormen employed in the cperation. Jt 
is peculiarly adapted to raising coals out 
of a sh'p’s-hold, or bricks to a high build- 
ing, or any other things of the same, or 
similar, kind. The plan may be thus de- 
scribed :—If the machinery is to be adapt- 
ed to raising coals from aship,a single pul- 
ley is fixed to the mast, over which a 
stroug rope is passed; to one end is fixed 
a basket, into which the coals are thrown, 
and to the other a stage of any kind, to 
hold ene, two, or more men. Suppose 
the basket filled, the stage will be aloft; 
and the man or men mount a ladder, 
from which they step into the stage, and 
by their weight instantly raise the basket, 
The momentum of the man or men in 
the stage, gives motion to the basket, 
which is of course raised with an accele- 
rated velocity ; but the method of stop- 
ping the machine is very simple and easy. 
To raise any thing to the top of a build- 
ing, two strong scaffolding poles are fixed, 
and the pulley suspended between them ; 
the ladder rests against the cross-beatn 
that supports the pulley, and then the ope- 
ration is as before, But if the building is 
very high, then the mechanical power of 
the wheel and axis is used, in order that 
the man or men may only have to walk 
up a ladder to half, or one-third, &c. of 
the height to which the bricks, mortar, 
Stone, &c. areto be raised. Water may 
be raised by the same kind of machinery. 
. The operation may be seen almost any 
day at the vacant space at the end of 
Wiild-street, Lincoln’s-inn-fields. 
The patentee says: the basket is raised 
by one man, or by two alternately, and 
any given quantity of work can be done 
by two men, much easier than by four 
in the usual method. Two baskets, in 
the case of coals, may be worked out of 
the hold by two machines and two gangs. 
The machine is simple, and may be fixed 
at a small expense in a few minutes. 
By the present practice, whether the hold 
is ten or twenty feet deep, whcther the 
ship is worked at the rate of forty, or 
one hundred and forty chaldrons per 
diem, the same number of men are em- 
ployed, which, of course, is a waste of 
labour, to employ four men to perform 
or even one person. Mr. Thompson 
claims to be remunerated by his employ- 
ers in the proportion of one-third only 
of their actual savings: a fairer or more 
honourable mode we presume cannot be 
devised, and it should seem Surprising 
that it has not been used in many in- 
stances to which it is evidently well 
adapted. We intend, in a subsequent 
Number, to give a fuller description, ace 
companied with an engraving. 
Mii : ae 
MR. RICHARD TREVETHICK’S, and MR. 
ROBERT DICKINSON’s (ROTHERHITHE 
dud London), for a Method of stowing 
Cargoes of Ships, &c. by Means of 
Packages for contuining Goods, &c. 
Instead of the casks, trunks, &c. now 
used for packing, and securing from da- 
mage, articles of merchandise, whether 
in the solid or liquid form, the patentees 
Make ase of cast or wrought iron recep- 
tacies, made so close and tight as to be 
absolutely impenetrable to the external 
air and muisture. They are sv con- 
structed as to figure and shape, as to fit 
exteriorly to each other without the waste 
of room, which often takes place in the 
stowage of wooden casks. The forms 
adopted in this specification, aud which 
are considered as preferable to others, 
are the rectangular or hexagonal prism. 
In other cases, where economy of space 
is not very requisite, they employ cylin- 
drical vessels and chests, and they con- 
tend that whichever mode be adopted, 
still there will be a saving of room; and 
that, by their invention, a much larger 
quantity of goods can be stowed in an 
equal space, than when they are put 
into packages made of wood, the sides 
and ends of which are necessarily of 
considerable thickness. Another advan- 
tage resulting from this invention, is that 
water, oil, and various other fluids, as 
well as provisions of different kinds, will 
be better preserved from waste, putre= 
scency, leakage, depredations from. in- 
sects, and other living creatures in iron 
vessels, than in vessels made of wood. 
In some cases,the iron packages are re- 
commended tu be tinned or varnished.
