Improvements in Grain and like Elevators.
I, WILLIAM GREEN HERBERT of 18 Dale Street, Liverpool in the County of
Lancaster Dealer in Works of Art, do hereby declare the nature of this invention to
be as follows:-
=
The invention relates to elevators having an endless band or chain fitted with
buckets and capable of being lengthened and shortened. The object is to construct
such elevators in a simple and efficient manner.
The invention consists essentially in the combination of three axles fitted with
pulleys drums or equivalent carrying devices for the bands or chains and free to
rotate in fixed bearings in a frame with a movable axle fitted with a pulley drum or
equivalent carrying device, and an endless band or chain of buckets the whole being
disposed as hereinafter set forth.
Two axles are supported in bearings near the top of the frame, a third is carried in
bearings near the bottom of the frame beneath one of the two axles above mentioned
whilst the movable axle is carried in bearings, beneath the second of the upper
carrying axles above mentioned and its bearings are connected to the frame by
telescopic devices of any suitable character. The endless band or chain of buckets
makes a circuit from the carrying devices on the movable axle to carrying devices on
the lower of the axles in the frame thence over the carrying devices on the two upper
axles between which it forms a loop and finally back to the carrying devices on the
movable axle. The axle above the loose axle and the lower axle of the frame are
provided with pulleys connected by a driving belt or chain. The lower pulley is
coupled to its axle by a friction clutch or device that will allow of slip taking place

loose to allow of the necessary slip taking place. If desired the loop of the endless
band or chain of buckets may pass around a pulley drum or equivalent device carried
in movable bearings.
The endless band or chain of buckets receives motion by means of any suitable
motor and the substance elevated is delivered into a shoot in the usual manner, and
framework and connections are provided as is usual with such elevators. As the
movable axle is raised or lowered the loop between the upper axles becomes longer or
shorter.

I WILLIAM GREEN HERBERT, of 18 Dale Street, Liverpool, in the County of
Lancaster, Dealer in Works of Art, 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:-
The invention relates to elevators having an endless band or chain fitted with
buckets and capable of being lengthened and shortened. The object is to construct
such elevators in a simple and efficient manner.
The invention consists essentially in the combination of three axles fitted with
pulleys, drums, or equivalent carrying devices for the bands or chains and free to
rotate in fixed bearings in a frame with a movable axle fitted with a pulley drum or
equivalent carrying device, and an endless band or chain of buckets the whole being
disposed as hereinafter set forth.
Two axles are supported in bearings near the top of the frame, a third is carried in
bearings near the bottom of the frame, beneath one of the two axles above mentioned
whilst the movable axle is carried in bearings beneath the second of the upper
carrying axles above mentioned and its bearings are connected to the frame by
telescopic devices of any suitable character. The endless band or chain of buckets
makes a circuit from the carrying devices on the movable axle to carrying devices on
the lower of the axles in the frame thence over the carrying devices on the two upper
axles between which it forms a loop, and finally back to the carrying devices on the
movable axle. The axle above the loose axle and the lower axle of the frame are
provided with pulleys connected by a driving belt or chain. The lower pulley is
coupled to its axle by a friction clutch or device that will allow of slip taking place,
between the axle and its driving pulley; or when a belt is used it may be sufficiently
loose to allow of the necessary slip taking place.
If desired the loop of the endless band or chain of buckets may pass around a
pulley, drum, or equivalent device carried in movable bearings.
The endless band or chain of buckets receives motion by means of any suitable
motor the substance elevated is delivered into a shoot in the usual manner, and
framework and connections are provided as is usual with such elevators. As the
movable axle is raised or lowered, the loop between the upper axles becomes longer or
shorter.
Figure 1. is an elevation, Figure 2. a front view, and Figure 3. a vertical section
of an elevator constructed in accordance with my invention.-1. framing of metal, or
suitable material, 2. endless band or chain carrying buckets 3., 4. top carrying pulleys
and shaft, 5 under carrying pulleys and shaft, 6. 7. guide pulleys and shaft, 8. pulleys
and shaft carried in bearings 9. free to slide in grooves 10., 11. flexible band or chain
attached to the bearings 9 and coupled to the roller 12, 13 worm wheel on the
roller 12, 14. worm actuated by the hand wheel 15, 16. driving pulley, 17. chain gear.

page_text: The band or chain of buckets at its lower end passes round pulleys in a cage in the.
usual manner, and the cage is connected to the frame 1 by any suitable sliding or
telescopic appliances. In practice the frame 1 is secured over a hatchway or above
the grain or substance to be elevated in any convenient manner and the endless band
or chain of buckets is set in motion by means of power applied to the pulley 16. The
position of the cage and lower pulleys which dip into the grain or material to be
elevated are regulated by raising or lowering the pulley and shaft 9 by means of the
worm 14 and and wheel 13. The band or chain of buckets travel in the direction
shown by the arrows and the contents of the buckets are delivered at 18 into a shoot
or on to any suitable conveyer. Instead of a worm and wheel 13. 14. other gear may
be used or a weight may be applied to the bearings 9. to regulate the position of the
pulleys and shaft 8. The positions of the guide pulleys and shaft 6. 7. may be varied
or they may be dispensed with.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed-I declare that what I claim is :-
First In elevators having endless bands or chains of buckets the combination of
pulleys and shafts 4. 5. carried in fixed bearings with pulleys and shaft 8 carried in
movable bearings, for the purpose set forth.
Second-In elevators having bands or chains of buckets under my invention, the
combination with the pulleys and shaft 8 carried in movable bearings, or means of
adjustment, for the purpose set forth.
