page_text: I, HERBERT ALFRED LUCAS BARRY, of 15, Great George Street, in the City of
Westminster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to tip trucks or waggons such as are commonly used by
railway contractors; the objects of my present improvements being to simplify the
construction, increase the angle to which the truck is tilted and to reduce the cost
of manufacture.
The truck is carried on two pairs of gudgeons which project horizontally from
its' opposite ends and rest in trunnion bearings formed in the upper edges of two
vertical plates respectively mounted on fixed gudgeons which extend horizontally
from upwardly projecting portions of the opposite ends of the truck-frame; each
gudgeon working in a curved slot in the plate, struck from the centre of the other
gudgeon. Or each end of the truck is provided with a toothed sector which works
in a rack mounted upon the truck-frame. From the central portion of the rack,
the teeth are omitted, and the central portion of the toothed sector is formed with
a corresponding flat, the former serving as a seating for the latter, so that the
truck, when in its normal or upright position, is carried steadily.
Instead of carrying the truck in trunnion bearings formed in the upper edges
of two vertical plates respectively arranged at the opposite ends of the truck-frame,
the said plates being themselves mounted to oscillate on gudgeons, I carry the
truck upon two fixed plates or supports erected at the opposite extremities of the
truck-frame. Each of these plates has its upper edge formed as two tracks,
whereon two rollers, mounted on studs projecting from the end of the truck, travel;
these tracks terminating in upwardly projecting horns, which serve as stops to
imit the travel of the said rollers endwise. The sides of each plate or support are
formed as, or are furnished with, downwardly and inwardly inclined guides in
which another pair of rollers, projecting in a similar manner from the end of the
ruck, work.
As the truck is tilted, one of the rollers last referred to enters one of the down-
vardly inclined guides; and whilst this roller travels therein, one of the rollers on
which the truck is borne moves outwards, along the truck formed by the upper
edge of the carrying plate; the truck assuming its maximum angle of tilt when
he one roller reaches the bottom of t. guide and the other roller reaches the
uter extremity of its track.

in provements are equally applicable to trucks designed to tip endwise.
Dated this 27th day of October 1896.
I, HERBERT ALFRED LUCAS BARRY, of 15 Great George Street, in the City of
Westminster, 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 relates to tip trucks or waggons such as are commonly used by
railway contractors; the objects of my present improvements being to simplify the
construction, increase the angle to which the truck is tilted and to reduce the cost
of manufacture.
In the accompanying drawings are illustrated several modes of carrying my
invention into effect. Figs. 1 and 2 represent respectively an end and a side
elevation of a tip-truck which is carried by gudgeons at each end resting in
trunnion bearings formed in vertical plates mounted at each end of the truck.
Figs. 3 and 4 are similar views of another construction wherein toothed sectors
carried by the truck engage with racks mounted on the truck-frame. Figs. 5, 6
and 7 are respectively an end view, a side elevation and a plan of a modified con
struction; the truck being carried upon the upper edges of fixed plates which serve
as trucks and guides for rollers and studs mounted on the truck-ends.
According to the construction illustrated in Figs. 1 and 2, the truck a has in-
med sides and vertical ends and is carried on two pairs of gudgeous bb¹ which
project horizontally from its opposite ends and rest in trunnion bearings c cl
formed in the upper edges of two vertical plates d respectively mounted on fixed
gudgeons e el which extend horizontally from upwardly projecting portions f of
the opposite ends of the truck-frame. Each gudgeon e e¹ works in a curved slot g gl
formed in the plate d; the curve of each slot being struck from the centre of the
other gudgeon. In its normal or upright position, the truck is supported upon its
gudgeons bb, which rest in their respective trunnion bearings c c in the upper
edge of each side plate d; a certain effort being necessary to disturb the truck
from this position. Upon sufficient force being applied to tilt the truck laterally,
it turns, as regards each end, in one of the trunnion bearings cor e until the
rojection on the truck-body arrives in contact with the side of the oscillating
plate d. Each of the plates d, supporting the truck, then commence to turn about
one of the fixed gudgeons e or el mounted upon the truck-frame and to move in
the same direction as the truck; thus shifting the upper bearing laterally, and
allowing the truck to be tilted to such an angle as will ensure the complete dis-
charge of its load. The dotted lines in Fig. 1 shows the position of the truck in
the extreme angle of tilt.
According to the construction illustrated in Figs. 3 and 4, each end of the truck a
is provided with a toothed sector h which works in a rack i mounted upon the
truck-frame. From the central portion of the rack i, the teeth are omitted, the
surface being left flat, and the central portion of the toothed sector is formel with
a corresponding flat; the former serving as a seating for the latter, so that the

page_text: truck, when in its normal or upright position, is carried steadily. When the
truck is tilted laterally, it turns about the centre of the toothed sector h, and, at
the same time, owing to the teeth of the toothed sector meshing with the teeth
of the rack i, the axis of rotation is shifted laterally towards that side of the truck-
frame against and over which the truck-body is being tilted.
Referring to the construction illustrated in Figs. 5, 6 and 7, the truck a, instead
of being carried in trunnion bearings formed in the upper edges of two vertical
plates respectively arranged at the opposite ends of the truck-frame, the said plates
being themselves mounted to oscillate on fixed gudgeons, is carried upon two fixed
plates or supports ko erected at the opposite extremities of the truck-frame. Each
of these plates has its upper edge formed as two tracks kk, whereon a pair of
rollers, mounted on studs m m', projecting from each end of the truck, travel;
these tracks terminating in upwardly projecting horns, which serve as stops
to limit the travel of the said rollers laterally as regards the truck. The sides
of each plate or support are formed as, or are furnished with, downwardly and
inwardly inclined guides in which studs n' n², or another pair of rollers,
projecting from the end of the truck, work. The central projection divides the
two tracks k k and serves to maintain the truck in its normal or central position.
As the truck is tilted, one of the rollers n or n¹ enters one of the downwardly
inclined guides ; and whilst this roller travels therein, one of the rollers or
on which the truck is borne moves laterally along the track k'; the truck assuming
its maximum angle of tilt when the one roller n or n' reaches the bottom of its
guide and the other roller or reaches the outer extremity of its track kl.
Although, in describing my invention, I have referred to a side-tip truck, my
improvements are equally applicable to trucks designed to tip endwise.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I claim :-
1. A tip-truck constructed or operating substantially as herein described and
wherein the tilting of the truck causes the centre whereon the truck-body turns
to move laterally thus permitting of the truck being tilted to the requisite
angle.
2. The improved construction of tip-truck, arranged or operating substantially
as described with reference to Figs. 1 and 2 of the accompanying drawings,
wherein the truck is carried on two pairs of gudgeons resting in trunnion bearings
formed in oscillating end plates, the latter working on fixed gudgeons carried by
the truck-frame.
3. In a tip-truck, the employment of oscillating plates, such as d, having
curved slots through which pass fixed gudgeons, such as e e, in conjunction with
gudgeons, such as bb, projecting from opposite ends of the truck-body and resting
in trunnion bearings, such as c', formed on the said plates, substantially as
specified.
4. The improved construction of tip-truck, arranged or operating substantially
a- described with reference to Figs. 3 and 4 of the accompanying drawings,
wherein toothed sectors are employed at each end of the truck-body, the said
sectors working in racks carried by the truck-frame; a flat or plane surface being
left in the centre of each sector and rack for affording a stable bearing for the truck
when in its normal position.
5. The improved construction of tip-truck, arranged or operating substantially
as described with to Figs. 5, 6 and 7 of the accompanying drawings, wherein
the truck-body is provided at each end with a pair of rollers capable of a limited
travel on a laterally arranged fixed track; the displacement of the bearing centre
of the truck being effected by other studs or rollers, suitably disposed on the truck-
ends, and working in fixed guides attached to the truck-frame.
6. In a tip-truck, the employment of fixed carrying plates, such as k, furnished
with inwardly inclined guides, in conjunction with rollers and studs, such as

page_text: and n n³, carried by the truck-body, whereby the truck is supported and operated,
substantially as specified.
