Year: 1876

page_text: LETTERS PATENT to Thomas Turton, of Liverpool, in the County of Lancaster,
Iron and Steel Manufacturer, and Ernest Latham, of Birkenhead, in the County
of Chester, Engineer, for the Invention of "AN IMPROVED PORTABLE STEAM
ENGINE ADAPTED FOR RAISING, LOWERING, AND HAULING WEIGHTS AND
BODIES."
Sealed the 30th September 1876, and dated the 5th April 1876.
PROVISIONAL SPECIFICATION left by the said Thomas Turton and Ernest
Latham at the Office of the Commissioners of Patents on the 5th April
1876.
THOMAS TURTON, of Liverpool, in the County of Lancaster, Iron and Steel
Manufacturer, and ERNEST LATHAM, of Birkenhead, in the County of Chester,
Engineer. "AN IMPROVED PORTABLE STEAM ENGINE ADAPTED FOR RAISING,
LOWERING, AND HAULING WEIGHTS AND BODIES."
The object of our Invention is to provide an efficient and economically working
portable steam engine suitable for raising cargo from ships' holds, for raising building
inaterials in the erection of houses and construction of ships, for hauling timber, and
for raising, lowering, and hauling weights and bodies generally. For these purposes
we arrange and combine the several parts of the carriage, the boiler, and engine
with a specially arranged drum or drums on the crank shaft in the novel manner
illustrated on the accompanying Sheet of Drawings. A feature of novelty under
our Invention is the construction of the drum or druns, and a special feature of
arrangement consists in dispensing upon portable engines for the purpose named
with gearing, and employing a connecting rod of unusual length.
Fig. 1 is a side elevation, and Fig. 2 is half of a plan view, showing a drum
partly in section, both illustrative of our improvements.
u, framework; b, carrying wheels ; c, boiler; d, cylinder; e, guide rods; ƒ, sliding
block working on rods e, and attached to piston rod; g, connecting rod shown of
unusual length attached to sliding blocks f and to crank on shaft i. The drum j
is secured to the shaft at its outer end at by the jam nut 2, and is sup-
ported at the inner end at by the bearing k. The carrying piece is secured to
the frame a, and contains the shaft bearings m. It will thus be seen that the drum
consists of two principal parts j, which revolves with the shaft i and the carrying
piece l, in which the bearings for i are contained.

page_text: In applying our Invention to, say, raising cargo from a ship's hold a rope, chain,
or band is passed around the drum j, and led thence over a sheave or carrying
surface. Hooks, slings, or containers are attached to the rope, chain, or band, which
is wound on to or off from the drum j, and the cargo raised from and lowered to the
desired position.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Thomas Turton and Ernest Latham in the Great Seal Patent Office on
the 5th October 1876.
THOMAS TURTON, of Liverpool, in the County of Lancaster, Iron and Steel
Manufacturer, and ERNEST LATHAM, of Birkenhead, in the County of Chester,
Engineer. "AN IMPROVED PORTABLE STEAM ENGINE ADAPTED FOR RAISING,
LOWERING, AND HAULING WEIGHTS AND BODIES."
The object of our Invention is to provide an efficient and economically working
portable steam engine suitable for raising cargo from ships' holds, for raising building
materials in the erection of houses and construction of ships, for hauling timber, and
for raising, lowering, and hauling weights and bodies generally. For these purposes
we arrange and combine the several parts of the carriage, the boiler, and engine
with a specially arranged drum or drums on the main shaft in the novel manner
illustrated on the accompanying Sheet of Drawings. A feature of novelty under
our Invention is the construction of the drum or drums, and a special feature of
arrangement consists in dispensing upon portable engines for the purpose named
with gearing, and employing a connecting rod of unusual length.
Fig. 1 is a side elevation; Fig. 2, a plan view partly in section; and Fig. 3, an
end view, all of a portable engine suitable for raising, lowering, and hauling weights
and bodies.
a, framework; b, carrying wheels; c, boiler; d, cylinder; more than one cylinder
may be employed; e, guide rods; f, sliding block working on rods c, and attached
to the piston rod g; h, connecting rod attached to the crank i, and shown of unusual
length, so as to obtain a longer piston stroke, and thus dispense with gearing; j,
crank shaft; , reversing gear. Oscillating cylinders may be employed in some
cases. The winding drum is formed in two parts l, m. The outer or winding
portion is secured to the shaft j at its outer end by the conical bearing n and jam
nut o, and at its inner end works on the bearing 2 on the carrying piece q attached
}
to the frame a. The inner or adjusting and retaining portion m of the drum is free
to move on the bearing n on the winding portion 1, and is retained in position by
the ring 8. The rope, chain, or band employed for raising, lowering, or hauling is
secured at one end to the inner portion m, the other end passing through an opening
t on the winding portion 7.
By winding a greater or less portion of the rope, chain, or band on m the length
of the free end is adjusted. When the required length of free end is obtained the
inner portion m is prevented from turning on the outer portion 7 by means of a key
pin or like means, so that when motion is given to the shaft the rope, chain, or
band is wound and unwound on the drum as desired.
Having now described the nature of the said Invention so that others will be
enabled to carry our improvements into effect we claim,-
First. The combination of the inner and outer drums l, m, constructed and
arranged substantially as described and illustrated for the purposes set forth.
Second. The general arrangement of portable raising, lowering, and hauling
engines, so as to obtain a long piston stroke, and dispense with gearing.

page_text: Third. The general construction, arrangement, and combination of parts for the
purposes set forth.
In witness whereof, we, the said Thomas Turton and Ernest Latham, have
hereunto set our hands and seals, this Fourth day of October, in the year of
our Lord One thousand eight hundred and seventy-six.
