PROVISIONAL SPECIFICATION.
Improvements in Mechanical Tipplers for Discharging Coal or other
Minerals.
I, FRANCIS SYKES, of 68, Sackville Street, Barnsley, in the County of York-
shire, Draughtsman, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in mechanical tipplers for discharging
or ieeming the contents of colliery corves, tubs, or railway wagons, and the like.
The object of my invention is to prevent loss of time by causing the tippler, after
discharging or teeming to return with the empty corves or tubs, at a more
quickly speed than which it discharges or teems them, and is operated in a
manner so that both the teeming and the return speeds as well as the braking
or checking of the rotation of the tippler may be done by one and the same
operating lever.
With reference to the accompanying drawings my apparatus is shown in con-
nection with an ordinary rotary side tippler driven by friction_gear.
Fig. is a front view of the tippler and Fig. 2 à plan. The rollers A, A
which are loose on their spindles and rollers B, B', fast on shaft S support the
main frame of the tippler T. For convenience I show an extra wheel F fast
on the said shaft and to engage with the apparatus, but I wish it to be under-
stood that this wheel is not absolutely necessary, as the supporting roller B¹
with the rim suitably prepared may be used for the same purpose.
The operating lever L, has al short arm L fast on the same shaft
and hinged on to carriage C, which carries friction wheels or rollers K'and K.
K², & the loose end of the said carriage may be supported by a chain and
balance MM, shown in Fig. 1, but not in plan.
The rollers K2, K2 are fast on their spindles, which carry cog wheels gearing
with each other as shown by dotted circles Q. Q. A balance weight and lever R
may be provided to balance the overhang of the operating lever L.
The driving shaft D, revolving continually in the same direction carries with
it wheel W.
In the position as shewn in the drawings, the tippler would be in a state of
rest, but by pulling at the operating lever L in the direction of the arrow,
the friction wheel K would be forced into contact with the wheel F. and driving
wheel W, thereby communicating motion to the tipper. The return motion is
effected by pushing or pulling at the operating lever L in the opposite direction
and forcing the wheels K2 K2, into contact with the said wheels F and W, when
the rotation is thereby reversed by the cog wheels QQ, which being geared in
a suitable ratio causes the tippler to rotate quickly comparatively speaking.
Should the tippler, by the momentum given to it through the gearing, return
or rotate too suddenly after the pressure on the operating lever has been released
it may be checked, or braked by forming contact with the opposite gear &
thereby brought gradually to its normal position against the catch U. The

Improvements in Mechanical Tipplers for Discharging Coal or other
Minerals.
I, FRANCIS SYKES, of 68, Sackville Street, Barnsley, in the County of York-
shire, Draughtsman, 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 relates to improvements in mechanical tipplers for discharging
or teeming the contents of colliery corves, tubs, or railway wagons and the like.
The object of my invention is to prevent loss of time, by causing the tippler-after
discharging or teeming, to return with the empty corves or tubs at a more
quickly speed than which it discharges or teems them, and is operated in a
manner so that both the teeming and the return speeds as well as the braking
or checking of the rotation of the tippler may be done by one and the same
operating lever.
With reference to the drawings, filed with my Provisional Specification, my
apparatus is shown in connection with an ordinary rotary side tippler, driven
by friction gear. Fig. 1, is a front view of the tippler, and Fig. 2, a plan. The
rollers A, A, which are loose on their spindles and rollers B, B₁, fast on shaft S,
support the main frame of the tippler T. For convenience I show an extra
wheel F, fast on the said shaft and to engage with the apparatus, but I wish
it to be understood that this wheel is not absolutely necessary as the supporting
roller 13, with the rim suitably prepared may be used for the same purpose.
The operating lever L, has a short arm L¹, fast on the same shaft, and hinged
on to carriage C, which carries friction wheels or rollers K¹ and K2, K2, and if it
be desired the loose end of the said carriage may be supported, preferably by a
chain, and balance weight M, M, shown in Fig. 1, but not in plan. The
rollers K, K, are fast on their spindles, which carry cog wheels gearing with
each other as shown by dotted circles Q Q. A balance weight and lever R,
may be provided to balance the overhang of the operating lever L, or if necessary
to assist the said lever being moved for the return gear or vice versa.
The driving shaft D revolving continually in the same direction, carries
with it wheel W. In the position as shown in the drawings, the tippler would
be in a state of rest, but by pulling or moving the operating lever L in the
direction of the arrow, the friction wheel K' would be forced into contact with
the wheel Fand driving wheel W, thereby communicating motion to the tippler.
The return motion is effected by pushing or moving the operating lever L in
the opposite direction and forcing the wheels K2 K2 into contact with the said
wheels F and W, when the rotation is thereby reversed by the cog wheels Q Q,
which being geared together in a suitable ratio, causes the tippler to rotate
quickly comparatively speaking; during the return, or reversed motion.
Should the tippler by the momentum given to it through the gearing, return
or rotate too suddenly after the pressure on the operating lever has been released,
it may be checked or braked by forming contact with the opposite gear, and
thereby brought gradually to its normal position against the catch U.
The tippler may be made positive driving instead of frictional by providing

page_text: the rim of the tippler T and wheels B', F, K', and K2, K2, as well as the driving
wheel W with teeth.
For simplicity in the drawings I have shown the friction wheels or rollers F
and W, with only one groove in each, and corresponding projections or flanges
on rollers K and K2, K2, but for heavy and powerful tipplers such as require
more frictional surface in contact to drive them, I prefer to have more than one
groove and projections on the said rollers.
Further I have shown in the drawings, the carriage C of my apparatus as
being horizontal, and operated by a hand-power lever, but if the position of the
driving shaft D, be placed on or about the same horizontal line as the shaft S,
it is obvious that the apparatus would have to be in a vertical position, and in
the case of heavy and powerful tipplers, the said carriage may have one of its
ends suitably connected to a screw and hand-wheel or preferably to the piston
rod of a steam or hydraulic cylinder in lieu of the hand operating lever as
shown.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is
1st. An apparatus as described whereby a rotary tippler can be driven, and
reversed, or returned quickly after teeming, to its normal position for reloading,
and the rotating as well as the braking or checking of the tippler, is effected
by one and the same operating lever: substantially as and for the purpose herein.
specified.
2nd. In combination with a rotary tippler, a carriage C with its rollers and
gear, as herein described, to be operated either by hand, steam, or hydraulic
power, or any other suitable means, in either a horizontal, or a vertical position:
substantially as and for the purpose herein specified.
