PROVISIONAL SPECIFICATION.
Improvements in or relating to Shoots and Buckets for Cranes
and the like.
I, DAVID ROCHE, 50, Ranelagh Road, Ealing, London, W., Retired Mariner, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in or relating to shoots and buckets for
cranes and the like, the object being to enable the bucket to be readily tipped at
a desired height. I provide a guide which is pivotally carried by a shoot and
through which a rope or chain for raising the bucket passes, the aperture being
so arranged, such as a slot, as to bring the bucket into the required position for
tipping, which is effected by means of a catch or hook which engages upon a
projection upon the bucket and the continued movement causes the bucket to tip
on its pivot.

Improvements in or relating to Shoots and Buckets for Cranes
and the like.
I, DAVID ROCHE, 50, Ranelagh Road, Ealing, London, W., Retired Mariner, 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 improvements in or relating to schutes and buckets for
cranes and the like, the object being to enable the bucket to be readily tipped at
a desired height. I provide a guide which is pivotally carried by a schute and
through which a rope or chain for raising the bucket passes, the aperture being
so arranged, such as a slot, as to bring the bucket into the required position for
tipping which is effected by means of a catch or hook which engages upon a
projection upon the bucket and the continued movement causes the bucket to tip
on its pivot.

page_text: In order that my invention may be fully understood, I will now refer to the
annexed drawings, in which, for purposes of illustration
Figure 1 is a side elevation shewing my invention.
Figure 2, plan view of same.
Figure 3, plan view to enlarged scale of tilting frame and pivoted guide piece.
Figure 4, front view of tipping bucket to enlarged scale.
d is a frame pivoted at e to the limbs a, the angle of which is altered relatively
to the limbs a by means of the cord which passes through the block rattached
to the frame d, and the block attached to the stop piece c, said cord or rope
being secured to the cleat or other suitable fastening q. The schute f is slidably
carried upon the frame d. u are cords or the like which are secured to the bar v
and the bar v¹, this bar and schute being operated by the cords which passes
through the blocks t attached to the frame d and bar el respectively. The cord
passes through the block or eyelet s¹ and is secured to the cleat or fastening s
By this arrangement the position of the schute f may be adjusted upon the
frame d. This schute f carries the guides g; being a projecting piece or
bar for receiving the bucket h when being tipped. The tipping of the bucket h
is effected by the projections upon the bucket coming into contact with the
curved guides g, the dotted lines n and m shewing the stages of tipping. The
rope or cord o which supports the bucket passes through the slot 1 (Fig. 3) in
the guide piece j which is pivotally carried at in a frame k, which is in turn
pivoted at to uprights attached to the schute f, the frame & being provided
with two or more pivot holes for the purpose of enabling its position upon the
uprights to be adjusted. The functions of, the frame and guide piece jare
as follows. The bucket h is raised and the forked part 2 of the rope or cord o
enters the slot j and this will stop the twisting or swinging of the bucket and
bring it into position for the engaging of the projections with the guides g,
the continued upward movement of the bucket now takes a movement which
causes it to tip over as shewn by the dotted lines m through the action of the
frame k which takes a semicircular motion upon the pivot ¹ and thus the contents
of the bucket are discharged upon the schute f which may of course be of any
convenient dimensions. Upon the bucket being now allowed to descend it will
come into contact with the bar g¹ and then tilt back to its initial position, the
position of the pivot and the balance of the bucket being arranged for this
purpose. The stop pins or studs are for the purpose of preventing the bucket
tipping too far when discharging its contents, and also ensuring it returning to
its initial position when being lowered from its tipping position.
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:
1. In means for raising, tipping and lowering a bucket or the like in com-
bination, a bucket, a tilting frame, a pivoted slotted guide carried by said frame,
a schute slidably carried upon a frame pivotally attached to the structure, said
frame and schute being adapted to be operated by blocks and tackle, guides upon
said schute, pins or studs upon a tipping bucket adapted to engage upon said
guides for the purpose of tipping the bucket, stop pins or studs upon said bucket,
a bar upon the schute upon which said tipping bucket engages, a forked cord er
rope attached to said tipping bucket and engaging in the slotted pivoted guide
aforesaid, substantially as set forth.
2. In means for tipping buckets or the like, a tilting frame having a pivoted
slotted guide piece, curved guides adapted to engage upon pins or studs upon a
pivoted bucket, a forked rope or cord engaging in the slot in the pivoted guide
piece aforesaid and secured to the bucket through the medium of a bent handle
for the purpose of bringing the bucket into position for țipping.

and arrangement of the various parts, substantially as described and illustrated
herein and for the purpose set forth.
