VELLING TRAVERSING MACHINERY FOR RAISING AND LOWERING HEAVY BODIES."
This Invention relates to cranes, winches, and other hoisting and lowering
machinery or apparatus having travelling or traversing motions, or both, when the
working parts of such cranes or winches receive motion from a stationary engine
through an endless travelling band, chain, or belt, or from a revolving shaft.
object is to transmit motion from the endless band, chain, or belt, or from the shaft
to the gearing of the crane or winch for raising, lowering, travelling, and traversing
in such manner that undue strain shall not be thrown on any of the working
parts.
The
To carry my improvements into effect I employ in combination one or two pulley
shafts receiving motion from the endless rope, chain, band, or rotating shaft, and
two or more cross shafts provided with belts and pullies. Power is taken off from
one or two points in the length of the endless rope, chain, or band, or from the
rotating shaft by one or two pulley shafts on the travelling frame of the crane or
winch. The pulley shaft or shafts above mentioned is or are provided with two or
more pairs of endless straps, bands, or chains, a pair of which operate through fast
and loose pullies on the raising and lowering gear, a pair on the travelling gear,
and a pair on the traversing gear, when both travelling and traversing motions are
used; one belt of each pair is crossed.
It will be obvious that as all the motions are transmitted from the driving power
to the crane or winch through belting employed in combination with two or more
shafts which receive the power, less strain will be thrown on the working parts
than if the power were transmitted through gearing, thus ensuring less wear and
tear of the working parts, and a longer life to the apparatus. The crane and
travelling gear are constructed in any ordinary manner.

VELLING TRAVERSING MACHINERY FOR RAISING AND LOWERING HEAVY BODIES."
This Invention relates to cranes, winches, and other hoisting and lowering
machinery or apparatus having travelling or traversing motions, or both, when the
working parts of such cranes or winches receive motion from a stationary engine
through an endless travelling baud, chain, or belt, or from a revolving shaft. The
object is to transmit motion from the endless band, chain, or belt, or from the shaft
to the gearing of the crane or winch for raising, lowering, travelling, and traversing,
in such manner that undue strain shall not be thrown on any of the working
parts.
To carry my improvements into effect I employ in combination one or two pulley
shafts receiving motion from the endless rope, chain, band, or rotating shaft, and
two or more cross shafts provided with belts and pullies. Power is taken off from
one or two points in the length of the endless rope, chain, or band, or from the
rotating shaft by one or two pulley shafts on the travelling frame of the crane or
winch. The pulley shaft or shafts above mentioned is or are, provided with two or
more pairs of endless straps, bands, or chains, a pair of which operate through fast
and loose pullies on the raising and lowering gear, a pair on the travelling gear,
and a pair on the traversing gear when both travelling and traversing motions are
used; one belt of each pair is crossed.
It will be obvious that as all the motions are transmitted from the driving power
to the crane or winch through belting employed in combination with two or more
shafts which receive the power, less strain will be thrown on the working parts
than if the power were transmitted through gearing, thus ensuring less wear and
tear of the working parts and a longer life to the apparatus. The crane and
travelling gear are constructed in any ordinary manner.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an end view, Fig. 2 a side view, and Fig. 3 a plan view of apparatus
constructed under my Invention, having travelling and traversing motions.
In this arrangement motion is taken from an endless travelling band, chain, or
belt a, which gives motion to the pulley band shaft c. A rotating shaft might be
used to give motion to the share, in which case bevel gear would be employed.
d are pullies for causing the hand, chain, or belt to take a better hold on the
pulley b. The pulley band shaft care fitted in the framework e carried by the
wheels on the lines g. Secured to the pulley shaft c are the pullies h, i, j, which
give motion through the straight and crossed belts, ¹, 1, l, m, m, to the
pullies o, p, q, on the shafts ?', 8, t.
The pullies are loose on the shafts r, s, t,
and v, w, x, are handles for throwing the belts h, k, l, l, m, m³, into and out of
contact with the fixed pullies o, p, q. The pulley P, according as it is operated by
the belt or gives a to-or-fro travelling motion along the lines g to the frame-
work e through the gearing y. 8, shaft for conveying the travelling motion to the
lines at the other ends of the framework e. The pulley 9 gives motion to the
shaft t, which is carried from end to end of the framework c. The said shaft serves
to operate, by means of a sliding wheel thereon, the traversing gear of a crane or
winch carried on the lines =. The pulley o gives motion to the shaft 7, which is
carried from end to end of the framework e, and serves to operate the raising and
lowering gear of the crane or winch.
It will be obvious that motion might be taken from the endless band, chain, or
belt a at two points, instead of from one point only, and that travelling or traversing
motion only might be given to the crane or winch,

page_text: The above driving gear can be easily applied and adapted to travelling and
traversing cranes of ordinary construction with advantageous results.
It will be evident that the belt gearing might be attached to the crane or winch
direct, instead of to the travelling frame as above described.
Having now described the nature of my said Invention in such manner that
others will be enabled to carry my improvements into effect, I claim belt driving
gear for operating travelling and traversing cranes or winches, arranged substantially
as set forth.
In witness whereof, I, the said John Edward Skillicorn, have hereunto set
my hand and seal, the Nineteenth day of July, in the year of our Lord One
thousand eight hundred and seventy-six.
