PROVISIONAL SPECIFICATION.
Improvements relating to Apparatus for Lifting and Conveying
Grain and the like in Bulk.
I, FREDERIC WINBOLT STAVELEY, of 1 The Temple, Dale Street, Liverpool
in the County of Lancaster, Shipping Agent, do hereby declare the nature of this
invention to be as follows:-
My present invention relates to apparatus for lifting and conveying materials in
bulk, such for example as grain. In such apparatus, the grain or the like is first
lifted to the requisite height by means of an elevator consisting of a series of
buckets carried on an endless chain or band, and it is then delivered on to a
conveyer consisting of a travelling endless band by which it is conveyed to the
desired point of delivery.
My present invention has reference to the means for actuating the conveyer;
such means should be as simple and free from friction as possible, and in the case
of portable apparatus, it should be light and readily adaptable to suit the various
circumstances under which the apparatus may be required to work.
According to my invention, I drive the conveyer direct from the elevator as
follows;-
I select one of the revolving shafts or spindles of the elevator and continue it
through the elevator casing a sufficient distance to carry a chain wheel which is
firmly secured on the end of the shaft; generally speaking, the most convenient shaft
to make use of for this purpose is the shaft of the upper drum or pulley over which the
elevator buckets run, this shaft being usually driven directly from some source of power.
The conveyer, which consists of a frame of considerable length with a revolving
drum at each end round which the travelling band passes, has also a chain wheel
keyed on to the projecting end of the drum spindle nearest to the elevator, and I
gear the two said chain wheels together by an endless chain, so that the conveyer
band is driven directly from the elevator. The diameters of the chain wheels are
so selected as to give the proper velocity to the band of the conveyer.
The conveyer is carried by a swivel bracket from the elevator casing, and the
axis of the swivel is so placed that the conveyer can range through a considerable
angle both horizontally and vertically without materially interfering with the
fairness of the lead of the chain on to either of the chain wheels.
A deflecting pulley or pulleys may be fitted to deflect the chain so as to clear any
part of the apparatus which it might otherwise foul.

Improvements relating to Apparatus for Lifting and Conveying
Grain and the like in Bulk.
I FREDERIC WINBOLT STAVELEY, of 1 The Temple, Dale Street, Liverpool
in the County of Lancaster, Shipping Agent, 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 :-
My present invention relates to apparatus for lifting and conveying materials in
bulk, such for example as grain. In such apparatus, the grain or the like is first

page_text: lifted to the requisite height by means of an elevator consisting of a series of
buckets carried on an endless chain or band, and it is then delivered on to a
conveyer consisting of a travelling endless band, by which it is conveyed to the
desired point of delivery.
My present invention has reference to the means for actuating the conveyer;
such means should be as simple and free from friction as possible, and in the case of
portable apparatus, it should be light and readily adaptable to suit the various
circumstances under which the apparatus may be required to work.
According to my present invention, I support and drive the conveyer direct from
the elevator as shown in the accompanying drawings in which
Fig. I is a side elevation and Fig. II an end elevation; in both views the same
reference figures are used to indicate the same parts.
1 is the elevator casing and 2 the frame of the conveyer; all irrelevant details of
the elevator and conveyer are omitted, only so much being shown as is necessary to
illustrate the application of my present invention.
I select one of the revolving shafts of the elevator, as 3 and continue it through
the elevator casing a sufficient distance to carry a chain wheel 4 which is secured
on the end of the shaft; generally speaking the most convenient shaft to make use
of for this purpose is the shaft of the upper drum or pulley over which the elevator
buckets run, this shaft being usually driven directly from some source of power.
The conveyer, which receives the grain or the like from the shoot through the
hopper 6, consists of a frame 2 of considerable length with a revolving drum 8 at
each end round which the travelling band 9 passes. 10 is a chain wheel keyed to
the projecting end of the drum spindle 11 nearest to the elevator, and I gear the
two chain wheels together by the endless pitch chain 12, so that the conveyer band is
driven directly from the elevator without the intervention of intermediate shafting
and gearing as has hitherto been the custom. The respective diameters of the
chain wheels are so selected as to give the proper velocity to the conveyer
band.
13 is a flanged deflecting wheel running on the pin 14 which deflects the chain so
as to clear the shoot 5.
The end of the conveyer adjacent to the elevator is supported by the swivel
bracket 15 carried in the brackets 16 fixed to the elevator casing. The bracket 15
holds the conveyer by the eyes 17 which encircle projecting portions of the steps or
bushes in which the spindle 11 rotates, and it will be seen that this method of support
allows the conveyer to range through a considerable angle both horizontally and
vertically without materially interfering with the tightness or fairness of the lead
of the chain, as the axis for vertical movement is concentric with the chain wheel 10
and the axis for horizontal movement is close to the chain.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In combination with an elevator and a conveyer therefor, a chain wheel 4
secured to one of the shafts of the elevator, a chain wheel 10 secured to the
conveyer spindle 11, a driving chain 12 and deflecting pulley 13, and a bracket 15
supporting the conveyer so that the latter is adapted to be ranged horizontally and
vertically without interfering with the action of the chain, substantially as described
and illustrated.
2. The combination and arrangement of parts forming the improved means for
supporting and actuating the conveyer of an elevator directly from the latter, sub-
stantially as described and illustrated.
