page_text: I GEORGE REYNOLDS TURNER of the Vulcan Iron Works, Langley Mill, in the
County of Derby, Mechanical Engineer, do hereby declare the nature of my
invention to be particularly described and ascertained in and by the following
statement:
This invention refers to that class of Tipping Wagon capable of turning upon a
vertical axis so as to tip the contents at either end or at either side of the wagon
and has for its object 1st an improved method of mounting the body of the wagon
upon the frame-work so as to ensure greater steadiness than heretofore, 2nd so
mounting the body upon an intermediate framework upon which it is capable of
revolving and tilting, that in the act of tilting it shall open the end door or doors
and allow the contents to discharge themselves, and 3rd the application of an
improved catch whereby the body of the wagon is locked to the intermediate
frame-work self-actingly and which catch is readily released when it is required to
tilt the body of the wagon.
On the accompanying drawing Fig. 1. represents a side and Fig. 2. an end view
of a Tipping wagon embracing my improvements and Fig. 3. is a front view of the
improved automatic locking catch.
In all the views a. is the usual frame mounted upon wheels b. in the ordinary
manner. This frame a. carries a convex shaped iron casting or wrought-iron or
steel plate c. which in turn forms the support and base for the interior frame-
work d. the lower surface of which is formed concave so as to exactly correspond
with and fit upon the outside of the convex plate c. the central bolt e (as seen
dotted in Figs 1. and 2) which passes through both the convex and concave
surfaces serving to keep the parts in position and to form the vertical axis round
which the body is capable of revolving. f. is the body of the wagon, shewn in the
drawing as constructed of sheet metal but which could be constructed of wood or
other suitable material. This body is connected to the angle iron bar g. forming
the upper edge of the interior framework d. by means of a pair of horizontal
pivots or bolts h. and from this point the said angle iron bar g. slopes down as
illustrated in Fig. 1. to allow of the tilting of the body at that end of the frame-
work as indicated by the dotted lines. In the act of tilting and by the application
of the radial arms i. and curved connecting links or brackets j. as illustrated; the
door k, which is hinged to the bottom of the wagon is caused to open and thus

page_text: allow the contents of the wagon to be shot out or to be discharged-the upper
door . which is hinged to the rod m. at the top of the wagon opening outwards at
the same time. It will be observed that the upper edges of the hinge straps k¹
upon the bottom door overlap the lower edges of the top door when the two are in
the closed position (see Fig. 2.) and thus both are kept closed together.
My improved catch is illustrated in Figs 1. and 3. and consists of a hinged
flap n. slotted so as to pass over the projection formed upon the intermediate
framework and is provided on its front face with a sliding piece o. which enters a
'notch in the projection and has simply to be raised out of contact therewith to
allow the flap to be turned partially, upon its hinge (as seen dotted in Fig. 1.) when
the wagon is required to be tilted up-this improved catch locking itself self-
actingly when the body once more resumes the horizontal position. The trigger
arm p. hinged to the intermediate framework is provided on its underside with a
pin which, as the wagon body turns round its vertical axis is capable of taking
into one of a series of holes q. formed around the convex plate and thus facility is
afforded for locking the body in the position for tilting end ways or side-ways as
desired.

Having thus particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
1st The improved construction and arrangement of all-round tipping wagons
substantially as hereinbefore described and illustrated on the accompanying
drawing.
2nd The improved method of mounting the wagon body upon an intermediate
framework capable of turning around central axis and upon corresponding convex
and concave surfaces whereby increased steadiness is secured, in conjunction with
the improved mechanism for opening and closing the end doors substantially as
herein before described and illustrated on the accompanying drawing.
3rd The improved self-locking catch mounted and operated substantially as and
for the purposes herein before described and illustrated on the accompanying
drawing.
