Improvements Connected with Elevators.
I, GILBERT LITTLE, of The New Conveyor Co., Ltd., Brook Street, Smethwick,
in the County of Stafford, Chairman and Managing Director of the said Company,
do hereby declare the nature of this invention to be as follows:--
This invention has reference to elevators of the well known kind in which the
material is elevated by a series of buckets on a band or chain passing round a
drum or pulley in the elevator boot or base and round a corresponding drum
or pulley at the top. Heretofore no efficient means have been provided for
ensuring a regular feed of the material into the elevator buckets in the boot and
consequently the buckets have been liable to become jambed in the elevator boot
and the elevator band or chain broken. This defect is overcome by my invention
which ensures a regular feed of the material into the elevator boot and buckets
and my invention is carried out as follows:
Adjacent to the inlet in the elevator boot or base I provide a revolving feed
roller preferably consisting of two discs forming the sides of the roller with radial
divisional plates between dividing the roller into a series of compartments. This
feed roller is mounted on a shaft adapted to revolve in suitable bearings. Above
the feed roller is a hopper into which the material can be thrown or conducted
through shutes or openings thereto this hopper having an inclined bottom
extending through the outlet to the feed roller and carried down the elevator boot.
The area of the outlet from the hopper is regulated by a sliding door or by
other suitable means. When the door is opened the material slides down out
of the hopper and falls into the compartments of the revolving feed roller and
by it the material is delivered into the elevator boot and buckets. The feed roller
receives rotary motion from any convenient source and the quantity of material
is regulated by the sliding door at the outlet from the hopper or by the speed
of the feed roller.

following statement:―
This invention has reference to elevators of the well known kind in which the
material is elevated by a series of buckets on a band or chain passing round a
drum or pulley in the elevator boot or base and round a corresponding drum
or pulley at the top. Heretofore no efficient means have been provided for
ensuring a regular feed of the material into the elevator buckets in the boot and
consequently the buckets have been liable to become jambed in the elevator boot
and the elevator band or chain broken. This defect is overcome by my invention
which ensures a regular feed of the material into the elevator boot and buckets
and my invention is carried out as I will describe by referring to the accom-
panying drawings on which Fig. 1 is a sectional elevation of my invention
applied to an elevator and Fig. 2 is a sectional end elevation of the same but
with the elevator omitted.
Some
The same letters of reference indicate the same parts in both figures.
A is an ordinary elevator base or boot and a¹ is the inlet to the same.
of the elevator buckets are indicated by dotted lines and marked B. The arrows
shew the direction in which the elevator is intended to run.
Adjacent to the inclined inlet mouth a¹ in the elevator boot or base A. I provide
a revolving feed roller C preferably consisting of two discs el c³ forming the sides
or ends of the rollers with radial divisional plates c³ (in this case six in number)
fixed thereto and dividing the roller C into a series of compartments. This feed
roller is mounted on a shaft D adapted to revolve in suitable bearings E E
and receiving rotary motion as by a band on the pulley F from any convenient
source. Above the feed roller C is a hopper G into which the material can be
thrown or conducted through shoots or openings thereto, this hopper having an
inclined bottom gl extending through the outlet 2 of the hopper to the feed
roller Cat some distance above the centre of the same (see Fig. 1). The said
inclined bottom gl bends downwardly at g³ and extends partly round the feed
roller C and then the bottom is continued at g' below the feed roller and down
to the inlet a¹ into the elevator boot A. The sides go go of the hopper are carried
down to the inlet a¹ between the ends of the roller C and the hopper E E. The
area of the outlet g² from the hopper G is regulated by the sliding door H or by
other suitable means.
When the door H is opened the material slides down the bottom gl of the hopper
and falls into the compartments of the revolving feed roller C as it revolves in
the direction indicated by the arrow in Fig. 1 and is thereby delivered into the
elevator boot A and buckets B in regular quantities. The quantity of material
delivered into the elevator boot A is regulated by the sliding door H at the
outlet g² from the hopper G or by the speed at which the feed roller C rotates.
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:-
The combination with the base or boot of an elevator of the kind herein
referred to, of a hopper to contain the material to be elevated and made with an
inclined bottom and an outlet at the front and a revolving feed roller divided
into a series of compartments and arranged to receive the material in the com-
partments as it issues from the outlet of the hopper and to deliver the same into
the elevator boot and buckets in regular quantities, substantially as set forth.
