Improvements relating to Coal Tipplers and like Machinery.
1, JOSEPH MARTIN, of 13, Belmont Terrace, Aberaman, Aberdare, in the
County of Glamorgan, Mechanical Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention consists of improvements relating to tipplers and like machinery
employed for discharging the coal or other contents of tubs, wagons or boxes; in
small quantities for screening or other purposes.
The object of my invention is to provide simple and efficient operating mechanism
for such appliances, and to so arrange the same that with the continuous and
regular movement of the driving shaft the tippler shall be driven at a slow speed
during the period of discharge, but at a quick speed when empty, thus causing
the coal or other contents to be gradually and regularly deposited into the screen
or other receptacle, and obtaining quick return of the empty wagon, and
consequent saving of time.
In the application of my invention in one convenient manner to a tippler for
discharging the contents of coal wagons or tubs into a screen, I mount upon the
first motion shaft of the driving mechanism and elliptical or like wheel having
teeth which gear into a similar wheel mounted upon the second motion shaft. Ou
the second motion sbaft I mount an ordinary circular wheel for gearing into a like
wheel on the tippler. On the revolution of the first motion shaft by means of
power transmitted by belting or in any other convenient manner, a variable motion
I so form
is imparted to the tippler by the motion of the elliptical gearing wheels.
the elliptical wheels and arrange them upon their respective shafts that during the
period of discharge the tippler is driven at a slow speed, but on completion of
the discharge a quicker motion is imparted to it.
The wagon or tub to be discharged is placed within the tippler, which is con-
structed in any ordinary manner, and the driving gear is then set in motion, causing
the tippler to be slowly rotated until the wagon is emptied. On completion of the
discharge the elliptical gearing wheels will have arrived at such relative positions
that the tippler will be driven at an increased speed, and quickly returned to its
starting position for the withdrawal of the empty wagon. The elliptical of like
gearing wheels are so formed and arranged that during the latter part of the
revolution the speed of the tippler is gradually decreased, thus permitting of
its being brought to a standstill without excessive stress or shock upon the
machinery.
Instead of employing a toothed wheel in the second motion shaft for gearing
into a like wheel on the tippler I sometimes transmit the power from the second
motion shaft to the tippler by means of chain gearing, thus permitting the second
motion shaft to be fixed at any convenient distance from the tippler.
In another application of my invention, I dispense with toothed gearing, and
connect the first motion shaft with the tippler by means of chain gearing, making
one or both of the chain wheels of an elliptical or like form in order to obtain a
variable motion of the tippler. When employing but one wheel of an elliptical
form I provide a sliding or balanced wheel to take up the slack chain. I also
employ the chain and chain wheels in combination with spur or toothed gearing
arranged in varying forms to suit the particular purpose required.

modifications as may be uecessary in the adaption of my improved driving gear
to suit varying services, without departing from the essential features of my
invention.

1, JOSEPH MARTIN, of 13 Belmont Terrace, Aberaman, Aberdare, in the
County of Glamorgan, Mechanical 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:-
This invention consists of improvements relating to tipplers and like machinery
employed for discharging the coal or other contents of tubs, wagons, or boxes, in
small quantities for screening or other purposes.
The object of my invention is to provide simple and efficient operating
mechanism for such appliances, and to so arrange the same that with the continuous
and regular movement of the driving shaft the tippler shall be driven at a slow
spced during the period of discharge, but at a quick speed when empty, thus
causing the coal or other contents to be gradually and regularly deposited into the
screen or other receptacle, and obtaining a quick return of the empty wagon and
consequent saving of time.
In the accompanying two sheets of explanatory diagrams to be hereinafter
referred to, I illustrate six different arrangements of my improved driving gear.
In the application of my invention in one convenient manner to a tippler for
discharging the contents of coal or other contents from wagons or tubs into a
screen, I mount upon the first motion shaft A, Figure 1, Sheet 1, of the driving
mechanism an elliptical heart or other irregularly shaped wheel as B, having teeth
which gear into a similar wheel C'mounted upon the second motion shaft D. On
the second motion shaft I also mount an ordinary circular wheel E for gearing
into a like wheel F on the tippler G. On the revolution of the first motion
shaft A by means of power transmitted by belting or in any other convenient
manner, a variable motion is imparted to the tippler G by the motion of the
elliptical gearing wheels B and C. I so form the elliptical wheels and arrange
them upon their respective shafts that during the period of discharge the tippler
is driven at a slow speed, but on completion of the discharge a quicker motion is
imparted to it.
The wagon or tub to be discharged is placed within the tippler G, which is
constructed in any ordinary manner and the driving gear is then set in motion,
causing the tippler to be slowly rotated until the wagon is emptied. On completion
of the discharge the elliptical gearing wheels B and C will have arrived at such
relative positions that the tippler will be driven at an increased speed, and quickly
returned to its starting position for the withdrawal of the empty wagon. The
elliptical heart or other shaped gearing, wheels are so formed and arranged that
during the latter part of the revolution the speed of the tippler is gradually
decreased, thus permitting of its being brought to a standstill without excessive
stress or shock upon the machinery.
Instead of employing a toothed wheel in the second motion shaft for gearing
into a like wheel on the tippler I sometimes transmit the power from the second

page_text: motion shaft to the tippler by means of chain gearing as shown at Figure 2, thus
permitting the second motion shaft to be fixed at any convenient distance from the
tippler.
In another application of my invention, I dispense with toothed gearing, and
connect the first motion shaft A with the tippler G by means of chain gearing as
shown at Figure 3, using only one elliptical or other irregularly shaped wheel and
providing a sliding or balance pulley H to take up the slack chain.
In the arrangements illustrated at Figures 4 and 5 Sheet 2, I interpose a second
motion shaft D between the first motion shaft A and the tippler G, the first and
second motion shafts being connected by chain gearing and the second motion shaft.
and the tippler by ordinary tooth or other gearing.
At Figure 6 is illustrated an arrangement of my driving gear with two elliptical
or other irregularly shaped chain wheels, enabling me to dispense with the balance
pulley hereinbefore described.
I construct and arrange the tippler in any suitable manner, and make such
modifications as may be necessary in the adaption of my improved driving gear
to suit varying services, without departing from the essential features of my
invention.
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. In coal tipplers and similar machinery the use of an elliptical or like wheel or
wheels substantially as and for the purposes described.
2. The improved driving gear for coal tipplers and like machinery arranged
substantially as and for the purposes described and as illustrated in the
drawings.
