AN IMPROVED RAILWAY TIP WAGGON OR TRUCK
Year: 1885

page_text: I ROBERT SAVAGE of Herbert Street, South Melbourne in the Colony of
Victoria, Gentleman do hereby declare that the nature of my invention for "AN
IMPROVED RAILWAY TIP WAGGON OR TRUCK" and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:
My invention of an improved railway tip waggon or truck is designed for the
purpose of providing a waggon or truck having first a body with a partly circular
bottom or a body of any other shape fixed on partly circular rollers, the pintle at
each end being the centre of the circle and in which no part of the body or
carrying receptacle requires to be hinged; second, having gear so arranged as that
the tipping is accomplished by moving the pintles to one side or the other by
means of travelling nuts and screws, racks and pinions, by winding endless chains
or ropes on suitable pullies or by means of compound levers or other mechanical
arrangements calculated to draw or push the centre pintles to either side as
desired, such pintles travelling in transverse guides on the frame or support at
each end of the body and causing the body to roll as if part of a wheel to the
side at which it is to be discharged, said guides together with pins or teeth
underneath fitting into holes or racks across the bottom of the waggon preventing
the body shifting from its proper place or overturning at either side.
The waggon up to the underframe which supports the body is mounted on
wheels and constructed in the ordinary manner, and near each of its ends I fix the
end vertical frames which carry or have formed on them the transverse guides
having solid ends, and between which guides the pintles on the ends of the body
travel, and attached to such frames at each end is the tipping gear. The body is
made for the most part of iron, and its partly circular bottom or rolling frame will
rest and travel on the horizontal under-frame of the waggon, the side projecting
lips forming a shoot for discharging purposes. Toothed or trundled segments are
affixed to the outside of the circular bottom or rolling part and work in suitable
racks or holes formed in the top of the underframe and so ensure the steady .
movement of the body when worked by the tipping gear.
I also provide a tip waggon or truck on which mount two of my improved
bodies or carrying receptacles, and in this case I place them transversely across the

page_text: truck and arrange their controlling gear so that they tip towards one another and
through a hole provided in the under-frame. This description of a truck will be
useful for ballasting purposes.
Referring to my drawings,
Figure 1 shows a side, and Figure 2 an end elevation of a railway tip truck or
waggon constructed according to my invention, Figure 1 being broken away at its
end so as to show a section thereat.
Figure 3 is an end view of the body in its tipping position with the teeth or
spikes on its bottom engaged with the rack or notched plate which is affixed to
the frame of the truck.
Figures 4 are enlarged details of the pintle, nut, and screw.
Figures 5 show front and side view of one of the teeth.
Figures 6 show an alternative description of nut and draw pintle.
Figure 7 shows an alternative means of accomplishing the side tipping by
means of a pitched chain working on chain pulleys, while
Figures 8 and 9 show side and end elevations of a tip truck having the body
placed transversely across the truck for end tipping purposes and its pintles
supported on brackets thereon, and
Figure 10 is an end view of a side tipping truck showing the bottom of the
body flat and the rolling toothed segment affixed to the end of said body.
In Figures 1 to 5. A is the frame of the truck having end frames A¹, the top of
which is faced with the angle irons A³ to form a guide for the nut A³ which is
threaded to suit the transverse screw A4 supported in the bearings A formed at
the top of the angle iron stay brackets A6 as shown. A is a hand wheel for
working said screw. The inner side of the nut has an oblong recess A³ formed in
it for the reception of the pintle B¹ secured to the end of the body B which is of
the form shewn and has the two angle irons B2 rivetted to its side to form guide
flanges to retain the body in its proper lateral position. These angle irons work
against the plates B³ affixed to the transverse supports B4. B are the rack or
notched plates having their ends set as shewn to suit the shape of the body and
these plates are affixed to the end transverse supports B6 which are also mortised
out similar to the plates in which the teeth A° of the body gear, so as to cause it
to travel while being drawn by its end pintles. In the alternative construction of
nut and pintle shewn in Figures 6, the nut A³ has flanges at its ends so as to form
a recess to receive the forked strap C which with its pin C is secured to the end
of the body B having the bearing C2 affixed to it for said pin's reception.
In Figure 7 the pintle B¹ works in the guide bearing D which travels in the
guides D¹ when pulled either way by the endless pitch chains D³ passing round
the chain sheaves D³ as shown, and secured at its inner ends to said guide
bearing D.
The alternative construction of tip truck or waggon shown in Figures 8 and 9
consists of the body B supported on its end pintles B¹ which are supported in the
bracket bearings E and said body retained in position by a suitable catch on the
lever E¹, and under the body I provide the delivery shoot E' which is attached to
the frame of the truck. There are two bodies B supported on this framing and
these may be made to tip towards the centre instead of outwards as shown.
They are so constructed and supported as that when full they are inclined to tip or
overturn, and when empty they are inclined to right themselves again.
The side tipping truck-shewn-in Figure 10 has the rolling toothed segment F
affixed on its ends so that these support the weight of the body B and they work
in the rack or notched plate B³ which is secured to the frame of the truck.
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
í
! First. Constructing railway tip trucks or waggons with partly curved bottoms

page_text: spikes which gear or engage with a rack or notched plate affixed to the frame
substantially as herein described and explained.
Second. The alternative construction of such trucks or waggons with their
rolling toothed segments F affixed on the ends of the body B (which may be of
any shape) substantially as herein described and explained and as illustrated in
Figure 10 of my drawings.
Third. The alternative construction and support of the bodies of such trucks or
waggons substantially. as shown in Figures 9 and 10 where their tendency when
full is to tip or overturn and when empty to right themselves again.
Fourth. The combination of parts forming my tipping gear marked from A¹
to A and B substantially as herein described and explained and as illustrated in
Figures 4 of my drawings.
Fifth. The combination of parts forming my alternative tipping gear and
marked from A to A and C to C substantially as herein described and explained
and as illustrated in Figures 6 of my drawings.
Sixth. The combination of parts forming my endless chain tipping mechanism
and marked from D to D³ substantially as herein described and explained and as
illustrated in Figure 7 of my drawings.
