I, CARL SCHLICKEYSEN, of Rungestrasse 17 and 18, Berlin, Germany, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a construction of chain-bucket elevator that can travel
in a path of any desired form and whose buckets have an arrangement whereby
they become automatically charged with the material to be transported, and
automatically discharge the same at the place of delivery. The arrangement may
also be such that a portion of the buckets are charged with one kind of material.
and another portion thereof are charged with a different kind of material, these
different materials being discharged either at the same or at a different locality.
At the same time, the use of the usual distance bolts passing through the buckets,
which is so inconvenient for the conveyance of solid and semifluid. bodies is done
away with.
The above advantages are attained, generally speaking, by propelling the elevator
instead of by means of the usual distance bolts, by means of lateral rollers whichi
engage with the driving wheels, the part of the distance bolts which usually pass
through the buckets being transferred to the outer surfaces of the narrow sidea
thereof, and the buckets being also each provided with pins by which they effect
the opening of the device for supplying the material to be transported and with
discharge flaps that are opened at the place of delivery. The chains are caused
by suitably shaped guido rails to travel along the desired path. The construction
of the chain buckets for the above purpose is as follows:-
The links of the elevator chain consist of rectangular frames, the sides of which
of flat section are stiffened by the transverse end bars. These separate link frames
are connected together by connecting links pivotted to pins on the frames which
are spaced at equal distances apart, that is to say, the distance between the two
pins on a link frame is the same as the distance between the pins of two contiguona
link frames. The said pins are extended and carry beyond the connecting links:
rollers, which run on the guide rails, and which also engage with the spaces
between the teeth of the driving wheels. The buckets, which are of a downward
tapering shape, fit into the link frames, and are secured thereto by any suitable
means. The guide rails are of angle iron section, the rollers of the buckets run-
ning upon the horizontal flange thereof, there being a pair of continuous rails for
the chain buckets passing from the charging locality to the place of delivery, and
another pair for the buckets passing back to the charging locality.
Each pair can be formed with one or more bends for guiding the chain buckets
in any desired direction; at the bends of the guide rails the chain buckets are
prevented from leaving them by providing either counter-rails or guide pullies
which retain the rollers in position.
The chain buckets may also be mainly guided by passing over suitably placed
guide rollers, and guide rails only he provided at certain parts of their path, where
the material is charged into them, and where the charges are emptied into shoots.

page_text: At these points, the chain buckets may be arranged to travel on horizontal guide
rails; at the loading station they pass under one or more hoppers containing the
material, and which have sliding bottoms to which are pivotted rocking levers
so arranged at the sides of the hopper that, as the buckets pass underneath them,
pins projecting therefrom come in contact with the levers and turn them so as
to cause the bottom to slide open, and allow the contents of the hopper to fall into
the bucket.
When the pins liave passed the levers, balance weights connected to the latter,
cause them to turn back into their original position, thereby closing the sliding
bottom again. When a certain number of the buckets are to be charged with one
kind of material and another sot with a different material, there are arranged two
hoppers over the buckets, and the levers of the hoppers and the pins of the corres-
ponding set of buckets are arranged in different positions, so that the pins of the
buckets that are to receive material N° I will only act upon the levers of the
hoppers for material N° I, and the same with regard to the hoppers and buckets
for material N° II.
For automatically discharging the contents of the buckets into the shoots at
the place of delivery, the bottoms of the buckets are made to drop open on a hinge
at one end.
Pivotted thereto are catches that, when the bottom is closed, engage with a rail
or stud on the side of the bucket.
Above the shoots are arranged fixed pins that project in the path of the hook
of the said catches, so that as the buckets arrive over the shoots, the pins force the
catches off the rail or stud, and the bucket bottom, thus losing its support, drops
open and discharges the contents. As the bucket travels onwards it passes over a 2
roller. carried in fixed bearings which first presses on the bottom so as to turn it
upward on its pivot into the closed positions, and then acts on a tail of the catch
so as to turn this back into tho engaged position.
If there are two kinds of material, N° I and II in two sets of buckets, to he
delivered respectively into a different shoot, then the before described opening 3
devices are arranged in a similar manner to those of the charging devices, so that
the pin over shoot for I will only act on the catch of bucket containing
material N° I, and the sanie with regard to shoot for N° II.

Improvements in Chain-bucket Elevators.
I, CARL SCHLICKEYSEN, of Rungestrasse 17 and 18, Berlin, Germany, Manu-
facturer, 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 a construction of chain bucket elevator that can travel
in a path of any desired form and whose buckets have an arrangement whereby
they become automatically charged with the material to be transported, and
automatically discharge the same at the place of delivery.
The arrangement may also be such that a portion of the buckets are charged
with one kind of material and another portion thereof are charged with a different
kind of material. At the same time, the use of the usual distance bolts passing
through the buckets, which is so inconvenient for the conveyance of solid and semi-
fluid bodies, is done away with.

page_text: The above advantages are attained, generally speaking, by propelling the
elevator, instead of by means of the usual distance bolts, by means of lateral rollers
which engage with the driving wheels, the part of the distanco bolts which usually
pass through the buckets being transferred to the outer surfaces of the narrow
sides thereof, and the buckets being also each provided with pins by which they
effect the opening of the device for supplying the material to be transported and
with discharge flaps that are opened at the place of delivery. The chains are
caused by suitably shaped guide-rails to travel along the desired path.

The elevator is shewn in the accompanying drawings, in which Fig. 1 is an
arrangement of the elevator in side view. Fig. 2 is an arrangement of the guide
rails for the elevator, Fig. 3 is an arrangement of the elevator buckets on the
driving and turning wheels. Fig. 4 is a plan view of a part of the chain which
carries the elevator buckets, Fig. 5 is a vertical section through the charging
hopper with an elevator bucket beneath it, Fig. 6 is a vertical section through
an elevator bucket with its bottom opened.
The links A of the elevator chain consist of rectangular frames, the sides a of
which, of flat section, are stiffened by the transverse end bars b. The separate
link-frames A are connected together by connecting links c pivotted to pins a¹
(Fig. 3) on the sides a, which are spaced at equal distances apart, that is to say,
the distance between the two pins on a link frame is the same as the distance
between the pins of two contiguous link frames. At the ends of the pins a¹ are
fitted rollers c¹ which are able to rotate and serve to guide the elevator-chain on
the guide rails d (Figs. 2 and 6). These rollers c¹ engage with the spaces e between
the teeth of the driving wheel f.
The buckets 9 which are of a downward tapering shape, fit into the links A of
the elevator chain and are secured thereto by any suitable means.
For guiding the elevator buckets in any desired path the guide rails d (Fig. 2)
are constructed, leading from the place for charging, the buckets g to the place of
delivery and back again so that a change in the direction of the path of travel
of the buckets may be made as often as desired. The rollers c¹ of the chain
frames A which pass along the guide rails d run upon the horizontal flange of the
said rails. These guide rails d.may also be bent; at sharp beuds counter rails h
or guide pullies are provided (Fig. 2) which prevent the rollers c' from leaving
the direction determined by the guide rails.
As shewn in Fig. 1 the elevator buckets can be passed under the charging
hoppers where they can be loaded with the goods to be transported and then
carried to the higher and distant place of delivery (Fig. 1). It is also possible
to arrange for the automatic charging and discharging of the elevator buckets.
For this purpose the charging hoppers and the elevator buckets 9 are of special
construction. The charging hoppers, which are fixed on a frame t, are provided
with sliding bottoms t which move in the line of travel of the elevator buckets.
In Fig. 1 the bottoms t¹ of the charging hoppers are shewn in a half-open
position. The opening and closing of the bottoms of the charging hoppers occurs
automatically in such a way that when a bucket comes under the mouth of a
hopper the bottom will open and the contents fall into the bucket g, whereupon
the bottom will automatically close again. To effect this the rocking levers l'are
attached to the sides of the hoppers and are connected with the bottoms t¹ by.
means of the pins u on the latter working in slots in the levers, so that the
bottoms ¹ open the mouths of the hoppers when the levers 7 swing in the direction
of travel of the elevator and close them again when the swing is in the opposite
direction.
This double movement of the bottoms is automatically effected by the pins mm
projecting from the clevator buckets, which pins, in the course of their travel,
catch against the levers and carry them along so that the bottoms t¹ are opened
and the material for transport falls into the bucket underneath. When the
pins m m have passed the lovers 1, balance weights n attached to the latter cause
them to swing back, whereby the bottoms close the hopper openings again.

page_text: When all the buckets are to be charged with one material, only one charging
hopper is of course, necessary. When, on the other hand, a certain number
of the buckets are to be charged with material. No I and another set with
material N° II two hoppers i and are arranged. In this case it is only necessary
to take care that the pins m m' are in such a position or of such a length that the
elevator bucket with pin m shall open the hopper i and that with the pin m' shall
open the hopper i', whereby the contents of each hopper will fall into the bucket
destined therefor. The discharging of the buckets can also be made automatic.
For this purpose the bottoms are hinged on to the sides of the buckets (as shewn
on the right of Fig. 1) in such a way that the bottoms open over the delivery
shoots and automatically close again when the materials have been allowed
to fall thereinto. The arrangement is as follows:-
An angle piece is pivotted at its apex to the side of the bottom v of the
bucket gi the arm of this angle piece is hooked at the end. This hooked end
can be pushed over the curved end of a rail to fixed on the side of the bucket by
turning the angle piece after the bottom has been closed, so that the latter
is held in the closed position. To open the bottom it is only necessary to disen-
gago the arm from the rail 10, whereupon the bottom will fall. The requisite
movement of the arm may be effected by a fixed pins situated in the path of
travel against which the arm strikes.
When the material has been discharged a fixed roller to placed directly under
the path of the elevator bucket closes the bottom and strikes against the arm
of the angle v¹ so that it pushes the hook-formed end of the arm over the rail 10,
whereby the bottom v is secured in the closed position.
If there are two or more kinds of materials to be conveyed by the buckets, the
discharging can easily be arranged for the delivery of material N° I, for example,
into shoot and material N° II into shoot . In this case two pins s are located
in the line of travel of the arins, which will be of different lengths; one of the
pins will open the bottoms of those buckets which are loaded with material N° I
whilst the other will open the bottoms of those buckets which are loaded with
material N° II.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. A bucket elevator, whose buckets can travel in a path of any desired form
and in which the usual distance bolts passing through the bucket space are
avoided, characterised by the construction of an elevator chain of frames (A) con-
nected together by connecting links, to which links distance rollers (c¹) are
attached which engage with the spaces (e) between the teeth of the driving
wheel (f) and serve for guiding the elevator chain with its elevator buckets (9)
disposed in their frames (A) in a prescribed path on guide rails (d), where the
rollers (¹) are prevented from leaving the guide rails (d) where the direction of
the rails changes by counter rails (h) or guide rollers (¹).
2. In the bucket elevator referred to in Claim I the arrangement of the
buckets (9) with stope (m m¹) for opening the charging hoppers (i i¹) and of a
bottom flap (v) which is held in the closed position by a hook (t) engaging with a
rail (w) and on the other hand is released over any desired place by the contact
of the hook (1) with a pin (s) so that the material to be transported falls, where-
upon the bottom (v) and the angle piece (¹). are brought back into the closed
position by a roller (tol) situated close beneath the bucket (g).
