Improvements in Elevators and Screening Appliances.
We, THOMAS MILLS MASON, JOHN HENRY MASON, and ARTHUR MASON, of Brandon
Street, Leicester, in the County of Leicester, Engineers, do hereby declare the
nature of this invention to be as follows:-
The object of our invention is the construction of elevators for raising all kinds
of stone & other materials and deliver the same into a screen to be sorted at the least
cost & wear & tear. We dispense with the use of leather, rubber, hair & cotton
belts & such like material for carrying the buckets & in lieu of same we use chain
with attachment links of a suitable angle on which we fasten the buckets, the said
buckets we make of a particular shape & size to give proper delivery of the material
into the said screen, the said chain is driven on sprocket wheels with suitable gear.
I make a frame of wood or iron & on the top of this frame I put a taper or
paralell screen perforated with holes for sorting the material, the material is carried
up by the said buckets & delivered into the said screen which when sorted falls
into spouts & is delivered into carts or trucks or where required.

Improvements in Elevators and Screening Appliances.
We, THOMAS MILLS MASON, JOHN HENRY MASON, and ARTHUR MASON, of Brandon
Street, Leicester, in the County of Leicester, Engineers, 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 object of our invention is the construction of elevators for raising all kinds
of stone and other minerals & delivering the same into a screen to be sorted and
delivered into carts or trucks or elsewhere as required at the least cost and wear
and tear. Such being the object of our invention the following is a complete
description of same, reference being had to the accompanying drawings forming a
part of this specification in which Fig. 1 is a complete view of the elevating &
screening appliance. Figs. 2 to 7 are details of the elevating apparatus.
We make a frame 5 of wood or iron of a suitable length, width, & height and
which we put on road wheels if required, on the top of this said frame we fix a taper
or paralell screen 4 of a suitable diameter and length, at the front end of the said
Γ

page_text: screen 4 we fix a sprocket wheel 3 for the purpose of carrying elevator buckets 2,
see Fig. 2, also at the front end of screen we fix pinion wheels for the purpose
of operating the said screen & buckets. We also fix a spout or shoot 7 on the said
frame at the front end of screen 4 which receives the material from the said buckets 2
and delivers it into the said screen which sorts the different sizes of material.
This falls into the different boxes 6, which we fix in the framework under the said
screen 4.
At the front end of these boxes we put doors if required so that when the said
boxes are full of the sorted material these doors can be raised & the material then
falls into carts or trucks or elsewhere as required.
Also by this invention we dispense with the use of leather, hair, indiarubber,
cotton & such like belts for carrying the said buckets 2 & in lieu of same we use
metal links with attachments 1. These links & attachments we make so that the
said buckets 2 can be fastened on each & work continuously, the said metal links
are made of an oblong shape any length & width to suit the different sizes of
buckets for dealing with various quantities of material, at one end of these links
we put a hook so that they can be attached to each other, also on one side we put
a plate or attachment of a suitable size, the said plate or attachment has three
legs or projections a, a which have holes in to receive bolts for bolting the said
buckets to same as in. Fig. 6, the said buckets are made & fixed on the said links &
attachments to give delivery of the material into the said spout or shoot 7.
When this elevating & screening apparatus is complete as Fig. 1, and used in
connection with a stone breaking machine, the broken material falls from the
jaws of the stone breaker and down a spout into the buckets 2 at the bottom end of
the apparatus, it is then carried up by the said pinion wheels & the buckets deliver
the broken material into the spout or shoot 7 and falls into the screen to be sorted &
is delivered into the boxes 6 ready for carting away as required.
Having now particularly described and ascertained the nature of our said inven-
tion & in what manner the same is to be performed we declare that what we
claim is:.
1. The elevating, screening & delivery arrangement all in combination as
described in the specification and drawings annexed.
2. The elevator link and attachment with bucket as shewn 1 & 2 in the accom-
panying drawings.
