page_text: I ALEXANDER SIM of Colloopey in the County of Sligo, Ireland, Miller, do
hereby declare the nature of this invention to be as follows:-
The object is to provide a conveyor for transferring sacks of grain and the like
from and to various places.
For the above purpose I combine a turntable with the required number of endless
travelling conveyors in such manner that sacks of grain or other suitable objects are
carried by any one of the conveyors to the turntable and are there directed to any
other conveyor to be carried to their destination.
The conveyors are made of chains connected by crossbars and pass around
carrying and driving rollers or wheels and over rollers or guides. One end of
each conveyor abuts against a turntable constructed in the following novel
manner :-
The turntable is secured to a central vertical pillar carried-and free to turn-in
suitable bearings. A freely moving sleeve surrounding the said pillar carries a
driving wheel which gives motion to a series of carrying rollers disposed in a
circular arc in radial bearings on the turntable. The said sleeve is also fitted or
made with an upper and lower wheels capable of being set in motion by a suitable
driving wheel. The axle of the driving wheel is carried in excentric bearings so
as to be capable of being raised and lowered in order that the said driving wheel
may be geared with the upper or lower wheel of the sleeve so as to reverse the motion
of the carrying rollers when necessary, or reversing gear may be applied to the
driving wheel. A rack is attached to the turntable in gear with a pinion by which
the said table is turned in the required direction.
The conveyors are horizontal or inclined, and may be jointed or have means for
raising or lowering the free end or ends away from the turutable if desired.
Conveyor chains are constructed of open links connected by flat strips hooked
over the ends of the said links and provided with lubrication apertures, such chains
being carried by sprocket or chain wheels having channels to convey oil or lubricant
to the chain apertures. The lubricant drops onto the sprocket or chain wheels from
a suitable container.
The flat strips are perforated so that the hooked ends may be rivetted to the body
of the strip and to crossbars.
1 ALEXANDER SIы of Collooney, in the County of Sligo, Ireland, Miller, do
hereby declare the nature of this invention and in what manner the same is to be
0 performed, to be particularly described and ascertained in and by the following
statement:-
The object is to provide a conveyor for transferring sacks of grain and the like
from and to variaus

page_text: For the above purpose I combine a turntable with the required number of endless
travelling conveyors in such manner that sacks of grain or other suitable objects
are carried by any one of the conveyors to the turntable and are there directed to
any other conveyor to be carried to their destination.
The conveyors are made of chains connected by cross-bars, and pass around

of each conveyor abuts against a turntable constructed in the following novel

The turntable is secured to a central vertical pillar carried and free to turn in

geared with the upper or lower wheel of the sleeve so as to reverse the motion of the

A rack is attached to the turntable in gear with a pinion by which the said table is
turned in the required direction.
The conveyors are horizontal or inclined, and may be jointed or have means for
raising or lowering the free end or ends away from the turntable if desired.
Conveyor chains are constructed of open links connected by flat strips hooked
over the ends of the said links and provided with lubrication apertures, such
chains being carried by sprocket or chain wheels having channels to convey oil or
lubricant to the chain apertures. The lubricant drops on to the sprocket or chain
wheels from a suitable container.
The flat strips are perforated so that the hooked ends may be rivetted to the body
of the strip and to crossbars.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a plan of an arrangement of conveyors and turntables under my
invention.
Fig. 2 is an elevation of part of one conveyor; and
Fig. 3 is a vertical section of the turntable partly in elevation.
a, a, a, are three endless travelling conveyors converging towards a turntable b.
The conveyors are formed of chains c passing round carrying or driving rollers or
sprocket wheels d and carrying crossbars e which form the bearing surface for the
sacks or other articles being transported. fare rollers on spindles attached to the
chains c and running on rails or guides y for supporting the chains c at intervals.
h is driving gear of any usual kind for giving motion to the conveyor-chains c.
i are carrying rollers between the turntable b and the conveyor chains c. gear
for driving the carrying rollers i. k is a series of carrying rollers with their axes
disposed radially and carried in bearings on the turntable b. The turntable b is
secured to a central pillar carried in bearings 6' and free to revolve therein. The
turntable is further supported by rollers 62 running on rails b³. m is a freely
moving sleeve surrounding the pillar and having secured thereto a bevel driving
wheel n which gives motion through the gearing o to the series of carrying rollers k.
The sleeve m has also secured thereto an upper and a lower wheel p, p by which
such sleeve may be caused to revolve. q, is a driving wheel mounted on a shaft g
carried in excentric bearings r so that such wheel q can be caused to engage with
either of the wheels p, p, and thereby cause the sleeve and with it the gearing o
and rollers to revolve in either direction. worm and wheel for operating
the excentric bearings. s is a sprocket or other wheel on the shaft q' by which
motion can be communicated to such shaft from any desired moving part of the
apparatus.
Any other desired form of reversing gear may be used instead of the wheels p p

so that the carrying rollers are presented to any two of the conveyors a, a', a².
As shown, the carrying rollers connect the conveyors a', a², and sacks or other
articles placed upon the conveyor a¹ at its outer end are conveyed along to the
carrying rollers k and by them transferred to the conveyor a³ which delivers such
sacks at its outer end as desired; or the conveyors and rollers may be caused to.
travel in the reverse direction if required.

construction of the sprocket-wheels and conveyor chains under my invention..

are made in the rim opposite to the joints of the chain c through which lubricant
supplied to the channel 2 by a pipe 4 can flow on to the said chain. care apertures.
in the flat strips for passage of the lubricant. The chain c is made of open links c¹
and flat strips alternately, the ends of the flat strips being turned over the
links and rivetted to the body of the strips and to the crossbars e, as shewn.
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 :-
First. The combination of a turntable having carrying rollers with two or more-
conveyors substantially as and for the purpose set forth.
Second. A turntable with carrying rollers constructed and operating substantially
as and for the purpose set forth.
Third. The construction of conveyors and conveyor-chains substantially as set
forth.
Fourth. Lubricating conveyor-chains through perforations or channels in sprocket
or carrying wheels substantially as set forth.
