COMPLETE SPECIFICATION.
Improved Automatic Locking Apparatus for the Bodies of Dumping
or Tipping Wagons.
I ROBERT HUDSON, of Gildersome, near Leeds, in the County of York, Engineer
and Ironfounder, 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 has reference to apparatus for automatically locking in the travelling
position the body of a wagon known as a "dumping wagon such body being usually
supported by and between a pair of standards or pedestals mounted upon the under-
framework, by means of either rollers or segments of rollers, or by one, two or more
trunnions on the said body, and consists in an improved catch or catches and in one
or more suitable part or parts on one or both of the said standards for the lower end
of the catch or catches, which is or are turned or bent sideways for taking there-
under-The said catch or catches is or are in connection with the body of the wagon
and in proximity to the aforesaid rollers or segments of rollers or trunnions, and so
mounted as to be capable of turning freely on a pivot or pivots and of being turned
sideways by hand for releasing the body when required to be tipped, and on the body
being turned back to its normal or travelling position, of automatically locking and
maintaining it in such position during loading and travelling.
In a wagon wherein the body is mounted on two trunnions at each end, one
automatic catch is sufficient either at one or both ends thereof; and in a wagon the body
of which is mounted and turns upon segments or rollers, or when the body has one or
more than two trunnions at each end, two of the automatic catches are preferred at
one or both ends thereof.
In the annexed two sheets of drawings like letters refer to like parts wherever they
occur.
Fig. 1. sheet 1. shews in end elevation the application of my improved locking
apparatus to a wagon mounted upon segments.
Fig. 2. shews its application to a wagon with the body mounted upon rollers.
Fig. 3. shews its application to a wagon with the body mounted upon a single
trunnion at each end or side.

page_text: Figs. 4. and 5. sheet 2. shew in end and partial side elevation its application to a
wagon having the body mounted upon two trunnions at each end, and
Figs. 6, and 7. shew in end and partial side elevation its application to a wagon
with the body having three trunnions at each end; and the same apparatus is also
applicable to wagons having a greater number of trunnions.
a, is the underframing,-b, the standards or pedestals mounted thereon, c, the body,
d, the trunnions, d 1 the segments, d2 the rollers, e, the automatic locking catch or
catches mounted and capable of turning freely upon the pivot or pivots f, so as to be
easily turned sideways by hand for unlocking the body for tipping, 9, the lip or part
or parts of the standard or standards beneath which the hook-like end e 1 of the
respective catch or catches automatically falls or fall during the turning back of the
body from its tipped to its normal or travelling position as shewn in all the Figures,
and thus locking it and preventing accidental tipping; h, are stops for receiving the
catches both in the locked and unlocked positions.
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 :-
In a dumping or tipping wagon, the automatic locking apparatus, comprising one or
more catch or catches such as e, and a lip or lips or projection or projections such as g,
on the standard or standards b, for automatically locking the body of a wagon in its
travelling position, substantially as hereinabove described and shewn in the drawings.
