COMPLETE SPECIFICATION.
Improvements in Tip Wagons or Trucks.
We, ROBERT HUDSON, of Gildersome Foundry, near Leeds, in the County of
York, Engineer and Iron Founder, and WALTER SKELTON HUDSON, of Gildersome
Foundry aforesaid, 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 in tip wagons or trucks. In the follow-
ing description thereof reference will be made to the accompanying drawings,
of which Fig. 1 is an end view of a tip-wagon constructed according to this inven-
tion, Fig. 2 a partial vertical central longitudinal section thereof, and Fig. 3 a
partial horizontal section thereof.
The end standards for supporting the body 1 of the truck are each formed, as
shown to a larger scale in partial elevation in Fig. 4, in plan in Fig. 5, and in
broken vertical section in Fig. 6, of a thin metal plate 2 bent to suit the correspond-
ing end of the underframe 3 and secured thereto by means of a pair of bolts 4,
around which the edges of the plate 2 are curled as clearly shown in Figs. 3 and 4.
The bolts 4 also serve for securing in place the rocking-way 5, between which and
the plate 2 there is interposed a cover-plate 6. The cover-plate 6 may, however, be
omitted. The construction of standards in this manner effects a great saving in space
occupied, labour, and cost, as compared with the ordinary construction. To each end
of the wagon-body 1 is fixed a rocker 7 that rests upon the corresponding rocker-
way 5 as shown in full lines in Figs. 1 and 4. These rockers 7 are formed of bars
of angular section (they may, however, be of channel section) and both they and
the rocking-ways 5 have turned up ends 7" and 5" respectively in order to prevent
the wagon-body 1 from leaving its underframe 3 when tipped laterally, as indicated
in dotted lines in Fig. 1. The ways 5 have central raised curved portions 5b
fitting into corresponding recessed portions 76 of the rockers 7 to prevent the
wagon-body from sliding out of position when travelling or whilst being tippe:l.
Figs. 7, 8, and 9, are respectively an end elevation, a partial central longitudinal
vertical section, and a partial plan of a tip-wagon provided with rockers and
rocking-ways of modified form. In this case, the rocking-ways 5 are made to
form recesses 5° at their ends and the rockers 7 are provided with projections "
formed by curling their flanges, rivets 8 being passed through the eyes thus formed
and serving for securing the ends of the rockers 7 to the body 1 of the wagon.
The place of the recessed portion 7b shown in Fig. 1 is, in the wagon shown in
Figs. 7, 8, and 9, taken by a pin 9 that is fixed to the body 1 and is received in a
recess 5d in the way 5, which is carried by a girder 10 secured to the underframe 3
and the upper flange of which is supported by struts 11.
The arrangement in each case is such that in rolling the loaded wagon-body
from the position shown in full lines in Figs. 1 and 7 into that indicated in dotted
lines, the centre of gravity of the body and its load, as indicated by the dotted
lines C C³, is first raised slightly, then either descends, as indicated in Fig. 1, or
travels along in a nearly horizontal line as indicated in Fig. 7, and ultimately falls

page_text: suddenly and so far forward as to ensure that the wagon-body will not automatically
resume its normal position before becoming quite empty.
Fig. 7 shows a way 5 having end recesses 5°, like the way shown in Figures 7, 8,
and 9, but provided with a raised central portion 5 fitting in a corresponding
recessed portion 7b in the adjacent rocker 7.
•
Fig. 10 is half a transverse section and half an end elevation, and Fig. 11 is a
partial side elevation, of a tip-wagon the body of which is arranged to tip endwise
instead of laterally. In this case the wagon is provided with longitudinal ways 5
having recesses 5° at their ends and arranged to support rockers 7 that are secured
to the underside of the wagon-body 1. The rockers 7 are simple bars of L-section
(they may be of channel-shape in section) bent to fit the underside of the body 1
and riveted transversely thereon. The place of the projections 7° (Figs. 7, 8,
and 9) is taken by bars 7° received in recesses in the rockers 7 and secured by
means of bolts 7d passing through the body 1. A pair of bars 9" passing through
holes in the rockers 7 and bolted to the body 1, fit in recesses 5 formed in the
plates 5 and take the place of the pins 9 of the truck shown in Figs. 7, 8, and 9,
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. A tip wagon or truck constructed with standards formed of vertical thin
plates of metal bent to suit the ends of the underframe and secured to the
underframe by vertical bolts, substantially as hereinbefore described.
2. A tip wagon or truck standard constructed substantially as herein before
described with reference to and shown in Figs. 1 to 6 inclusive of the accompanying
drawings.
3. A tip wagon or truck having rockers and ways so constructed and arranged
that when the loaded wagon or truck body is being tipped by being rolled on its
rockers, the centre of gravity of the body and its load is first raised, then either
descends or travels along in a nearly horizontal line, and then falls suddenly and so
far forward into its extreme position as to ensure that the wagon or truck body
will not automatically resume its normal position before becoming quite empty,
substantially as herein before described.
4. Tip wagon or truck rockers and ways constructed, arranged, and co-operating
substantially as herein before described with reference to and shown respectively
in Figs. 1 to 6 inclusive, in Figs. 7, 8, and 9, in Fig. 74, and in Figs. 10 and 11,
of the drawings referred to.
