A SELF- ACTING CATCH FOR TIP-BUCKETS, BOXES, PANS, TIPPING-WAGONS AND THE LIKE
Year: 1885

page_text: I, ROBERT HUDSON, of Gildersome, near Leeds, in the County of York, Engineer
and Ironfounder, do hereby declare the nature of said invention for " A SELF-
ACTING CATCH FOR TIP-BUCKETS, BOXES, PANS, TIPPING-WAGONS AND THE LIKE,"
to be as follows:
This invention relates to automatic means for, and has for object the securely
holding in position, tip-buckets, boxes, pans, tipping-wagons and implements or
vehicles used for loading, unloading or otherwise conveying earth, minerals or
other material, whether loaded or unloaded, such tip-buckets, implements or vehicles
being suspended or mounted upon trunnions or their equivalent so as to be capable
of turning thereon in the action of tipping.
One of the said trunnions or axes I elongate in suchwise as to form a flat pro-
jection which is turned edgewise and upwards. To the suspension bow of a tip-
bucket or other implement in connection with such trunnion I attach a selfacting
catch which is capable of turning upon a joint pin or other centre of motion, this
catch being so formed as to embrace the said flat projection of the trunnion or axis
and prevent accidental tipping.
When it is required to "tip," the said selfacting catch is moved around its joint
pin or centre of motion in an arc of a circle so as to leave the flat projection of the
trunnion or axis above referred to, when tipping may take place.
On the bucket or other implement or vehicle resuming its normal position the
selfacting catch, by its own gravity falls upon and again embraces the said flat
projecting part of the trunnion and arrests the turning action thereof, the bucket
or other object becoming securely locked thereby. The construction of the self-
acting catch and the manner of attaching the same is such that it cannot resume
its position upon the flat projection of the trunnion until the bucket, implement, or
vehicle. has resumed its normal position. When desired both trunnions may be
formed and provided with a selfacting catch as above referred to.-The, projecting
part of the trunnion may be made the same shape as above described, but grooved
so as to embrace the catch instead of the catch embracing the trunnion.

Wagons, and the like.
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 relates to automatic means for, and has, for object the securely
holding in position,, tip buckets, boxes, pans, tipping wagons and implements.
or vehicles used for loading, unloading or otherwise conveying earth, minerals or
other material, whether loaded or unloaded, such tip-buckets, implements or
vehicles being suspended or mounted upon trunnions or their equivalent, so as to
be capable of turning thereon during the action of tipping. One of the said
trunnions or axes I elongate in suchwise as to form a flat projection which is
burned edgewise and upwards.
To the suspension bow of a tip bucket or other implement in connection with
such trunnion I attach a selfacting catch or pawl which is capable of turning freely
upon a joint pin or other centre of motion, this catch being so formed as to
embrace the said flat projection of the trunnion or axis and prevent accidental
tipping.
When it is required to "tip," the said catch or pawl is moved around its joint
pin or centre of motion in an are of a circle so as to leave the flat projection of the
trunnion or axis above referred to, when tipping may take place.
On the bucket or other implement or vehicle resuming its normal position, the
selfacting catch by its own gravity falls upon and again embraces the said flat
projecting part of the trunnion and arrests the turning action of the bucket or
other object and securely locks the same. The construction of the selfacting catch
and the manner of attaching the same is such that it cannot resume its position
upon the flat projection of the trunnion until the bucket, implement or vehicle has
resumed its normal position. When desired both trunnions may be formed and
provided with a selfacting catch as above referred to. The projecting part of the
trunnion may be made the same shape as shewn in front elevation Fig. 1. and
turned upwards as above described, but made thicker, and grooved vertically, so as
to embrace the catch or pawl, which in this case is made single so as to take into
the said vertical groove, instead of the catch embracing the projecting part of the
trunnion.
In the accompanying drawings Fig. 1, is a front elevation, and Fig. 2, a side
elevation of a tip bucket and its mountings,-a, is the bucket, b, b1', the trunnions
upon which it turns when being tipped, c, is the bow by which the bucket is
suspended, 62, is the flat projecting and turned up part of the trunnion b1,
e, is the selfacting catch or pawl, in double or link form for embracing the said
projecting part b 2, and locking the bucket in its upright or normal position, the
catch e, is mounted on the joint pin f, in the suspending bow c, and capable of
turning freely thereon,

page_text: When the bucket is required to be tipped, the catch e, is moved to the position
indicated by the dotted lines e 1, and during the tipping movement rests against
the projecting end 62 of the trunnion 6 1, Fig. 1, and when the bucket is returned
to its former position, the catch by its own weight drops upon and embraces the
projecting part 62, and thus automatically secures the bucket in an upright position
for being filled. Figs. 3, and 4, shew the projecting and turned up part 63, of the
trunnions 61, to be thicker and grooved vertically, or in double form so as to
admit of a single form of catch or pawl e 2. as shewn in side view Fig. 4.
It will be obvious that other forms of vehicles or implements previously
mentioned, may be similarly mounted and secured in and released from their
upright position as in the case of the tip bucket just referred to.

Having now 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
As means for securing and preventing tilting or tipping of a tip bucket, box, pan,
tipping wagon, or the like, a selfacting catch such as e, or e 2, and a specially
formed trunnion or projection, single or bifurcated, the arrangement and operation
being substantially such as described above with reference to Figs. 1, and 2, or as
described with reference to Figs. 3, and 4, of the drawings.
Dated this 23rd day of February 1886.
