Improvements in Wagon Tipping Devices.
SYDNEY ALBERT EVERETT, 40, Alpha Road Southville Bristol Mining
Engineer do hereby declare the nature of this invention to be as follows:-
1
The combination with a tippler, kick up, or tumbler, employed for empting
trams, tubs, or wagons containing mineral or other substances; of a mechanism for
producing a variable speed of rotation. Such mechanism consisting of two parallel
shafts or axes of revolution, not in the same straight line, each carrying a crank or
levor, or equivalent. contrivance, such levers, cranks, or equivalent contrivances
being connected by a link, or pin and slot, or their mechanical equivalent, in such
a way that the angular velocity of the driving axis is communicated to the driven
axis, which may either be the tippler axis, or be connected therewith by suitable
toothed or chain gearing, or other connection, in a variable ratio at different
points of the revolution.

SYDNEY ALBERT EVERETT 40 Alpha Road Southville Bristol Mining
Engineer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
My invention consists of the combination with a tippler, kick up, or tumbler
employed for empting trams, tubs, or wagons containing mineral or other
substances, of a mechanism for producing a variable speed of rotation. Such
mechanism consisting of two parallel axes of revolution or shafts, not in the same
straight line, each carrying a crank, or lever, or equivalent contrivance, such
cranks, levers, or equivalent contrivances being connected at their other extremities
by a link, or a pin and slot, or their mechanical equivalent, in such a way that the
angular velocity of the driving axis is communicated to the driven axis, which may
either be the tippler axis, or be connected therewith by suitable toothed, chain, or
other gearing, in a variable ratio at different points of the revolution.
In the appended drawings, Sheet 1 represents in elevation and plan one form of
the combination of such mechanism with a tippler.
D, D, is the driving shaft, which carries the crank D, C.
E, F, G, is the ring forming one end of the body of the tippler; it revolves
upon the rollers H, J, in the usual manner, and is provided with a pin B, the
relation of which to the tippler axis A, constitutes the driven crank.
The cranks A, B, and C, D, are connected by the link B, C.
The tippler, or driven, axis passes through A; and being parallel to the driving
axis D, D, but not in line therewith, the motion is transmitted from the shaft D, D,
to the tippler with the desired variations of velocity.

page_text: In the modification shown in elevation upon Sheet 2, D is the driving axis,
carrying the crank D, C. The pin C at the end of this crank works in a slot of
suitable form in the driven crank A, B. E, F, G is the tippler ring, supported
upon the friction wheels H, J; the motion is conveyed to it, from the driven
axis A, by means of a pair of toothed wheels L, K, and a sprocket wheel M,
and chain N, P, which engages with a sprocket ring attached to the tippler..
The combination is susceptible of a number of modifications,, by varying the
positions, proportions, and forms of the parts; the two arrangements illustrated
may be taken as types.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. The construction, combination, and arrangement in tipplers operated by
mechanical power, of a driving mechanism whereby a varying speed of rotation is
obtained; such mechanism consisting of two cranks connected by a link substantially
as hereinbefore described.
