Year: 1877

A Methodist preacher AurnS inventor.
Rev. Mr.. Bradley, member of the Will !
mington Conference, now preaching in
Dorchester co., Md, has invented a motive
mower which he calls Promethor," that
IS to distance steam, electricity, the Kelley
motor and all. We and other Peninsula
papers have spoken of the invention be-
fore, but now that one of the Promethers
is nearly constructed in Philadelphia a new
interest is aroused in its behalf. Mr.. 3.
claims that he has applied law of the hu-
man anatomy to mechanical purposes, viz
the force by which the pulsations of the
heart drive the blood through the system
is the power which he has turned to me-
chanical account, i'll connection with new
gas which he has generated. We take the
following description of the machine from
the Phila. Erening Herald:


THE MACHINE


is 4 simple framework with stationary pis-
tons fixed in chambers corresponding to the
the auricle and ventricle of the human heart;
the heart shaped cylinder moving upon the
pistons and not the pistons through the
cylinder. This movement meaSurably
represents the action of the heart, and is
not fanclful, but essential to the strength
andperfect working of the machine. Small,
spherical, heated cells or generators, cor.
responding to the human lungs, receive
jets of water, reduced by pressure to deli
cate spray, creating instantaneously an all
powerful and steady force, regulated in
quantity by the number of generators en-
ployed.


THE POWER


is an underlined, vaporous decomposition,
produced by the action of water in contact
with dry heat; the water in the operation
being perfectly decOmposed and effectng
u chemical phenomenon difficult Of desig-
nation.


THE HEATING


apparatus is enclosed in an alright cham
Der, the smoke being returned and con-
sumed. There Is consequently no discharge
of smoke or cinders. Locomotives will no
longer discharge their offensive burdens
into the eyes, ears and laps of travellers, nor
the escape of the steam boiler drown the
voice of conversation.


SPACE.


machine of one hundred horse power
does not occupy greater space than six
feet square and as many in hight, and
thrice that room will suffice for a machine
of the power of three thousand horses, and
so on to any requirement whatever.


INEXPLosIvE.


While there is scarcely any limit to the
power of this King of Forces, it is so dis
posed as to be perfectly harmless in the use.
There can be no rupture further than the
possible cracking of one of the generators,
which are of very small size and nearly in
dependent of each other. Mr.. Brady has
purposely ruptured them under pressure
of many thousand pounds but there is no
flying OFT, and they are so constructed as to
be removable at will.


GENERAL ECONOMY.


The comparative consumption Of fuel to
produce the same amount of force NAV be
estimated generally at less than one-fourth
of that required by steam power. The
saving cannot be stated with entire exact
ness until proven by use but the con-
sumption cannot exceed in bulk a fourth
ofthat required by the steam engine, and
the cost Of the Promethor as an engine is in
still less proportion, there being no bulky
boilers, smoke-stacks or other heavy adj
juncts This inventor does not believe that
any useful power can be developed from
any natural element without external aid
or heat in some form, and thinks that he
has economized that impOrtent element so
that no machine can be simplifed below
the standard he has obtained in the con
sumption of fuel.


SUMMING Up.


To sum up l may remark: First, that
the motor employed in this invention is a
wellknown agent, and one that is, beyond
comparison, powerful in action and easy o
management Second, that the mode o.
utilizing it is marvelously simple, origina
and perfect. Third, that its economy il
marked being as one to five, if not to six Of
eight, IN comparison with that of steam
Fourth, that it is managed so as to b,
positively non-explosiveand without DANCE
OF any stage. Fifth, that the machine i
suitable for all mechanical purposes, ant
finally it is unlike anything else in tn
world Of mechanics, and will excite an in
terest in economies, and revolutionize tn
present mode of propulsion in every de
partment Of mechanical motion. Th
machine and its capacities are not simply
great invention, they are an inspiration
utilizing the forces of nature by the princ
pies of natural laws, and confirming to tn
conceptions Of man, the psrfections of tn
Divine intelligence in His works. In fe,
weeks the public will have an opportunit
of seeing in operation Promethor of tn
power of fifty horses which is now nearl
ready for exhibition.
