stantially equal to the width of the bearing loop I I`
of the links, and the over-all width oi the offset
is substantially equal to the spacing between the
two bar loops I2 of the links.

The principal object of the invention is to pro

economical to manufacture and which can be
To' assemble the chain, the offsets of one of the
bars I5lis slipped into the bar‘l‘oops il of a pair of
links. A second pair of links is then turned up
easily and quickly assembled in any desired

lengths without the use of tools;
Another object of the invention is to provide a

signed for simplicity, economy, and efficiency.
When the chain is completed the links are self
locking. The hooks II cannot unhook since the
shoulders on the portion It strike the hooks lf2
of the adjacent link, and similarly the hooks I2'
cannot unhook since they strike the shoulders of
These will becomey more apparent fromV the follow«

sired to be understood that the same may be

a single centrally positioned bar loop II, and at
its other extremity a pair of similar spaced-apart

At the center portion of the link, between the
bar loops I2, is a sprocket notch I3, containing a
sprocket bearing face I4.
The links are used in conjunction with a series
of conveyer bars I5. The bars I5 may have any
desired length, depending upon the width re
quired for the complete conveyer.
The bars are oiTset,v as shown at I6, adjacent
each of their extremities and terminate in bear
ing ends I'I which are in axial alignment with the
main portion of the bar. It is preferred to employ
straight, round rods for the bar I5 to form the
oiTset I6 by heating the extremities of the bars
and deforming them in a punch press, thus insur

without departing from the spirit of the inven
tion.
Having thus described the invention, what is 40
claimed and desired secured by Letters Patent
isz
1. A conveyer chain consisting of a series of
bifurcated links, the furcations at each side of
the bifurcation being turned back upon them
selves to form a pair of hooked extremities; a
single bar loop at the opposite side of said link
in alignment with the bifurcation therein; and
an offset bar extending through the hooked ex
tremity of one link, thence extending longitudin
ally of said chain between the latter hooked ex
tremity and the bar loop of an adjacent link,
thence extending laterally of said chain through
lthe latter bar loop, thence returning longi
tudinally of said chain between said latter bar 55

loop and the other hooked extremity, thence pass
ing through said latter extremity to connect the
adjacent links together with said bar separating
the hooked extremities from the bar loops thereof.
2. A conveyer chain consisting of a series of
bifurcated links, the furcations at each side of
the lbifurcation being turned back upon them
selves to form a pair of hooked extremities; a
single bar loop at the opposite side of said link
and said double bar loops engaging said bars at
each side of said offset; and shoulders formed on
said links to prevent the adjacent links from un
hooking, all of said loops having an open side,
opening in the direction of the plane of said Ul
link, so that when said links are turned to a posi
tion substantially at right angles with each other
said loops may lbe slid from engagement with
said bar and with said shoulders.
in alignment with the bifurcation therein; and
5. A link for bar conveyers comprising a rela
an offset bar extending through the hooked ex
tively ñat body portion; a bar loop extending
from the mid-portion of one side of said body
tremity of one link, thence extending longi
tudinally of said chain between the latter hooked
extremity and the bar loop of an adjacent link,
thence extending laterally of said chain through
the latter bar loop, thence returning longitudi
nally of said chain between said latter bar loop
and the other hooked extremity, thence passing
through said latter extremity to connect the ad
jacent links together with said bar separatingv
the hooked extremities from the bar loops thereof,
the bifurcations in said links extending inwardly
therein beyond the position of said bars to form
openings through the links for the reception of
sprocket teeth.
3. A bar conveyer comprising a series of round
parallel bars; an offset formed in each bar ad
jacent each extremity thereof; a series of links;
a single bar loop on one side of each link; double
30 bar hooks on the other side of each link, said
single bar loops being engaged in the offset por
tions and said double bar loops engaging said
bars at each side of said offset; and shoulders
formed on said links to prevent the adjacent
links from unhooking, all of said loops having an
open side, opening in the direction of the plane
of said link there being an opening through each
of said links for the reception of sprocket teeth.
4. A bar conveyer comprising a series of paral
4.0 lel bars; an oifset formed in each bar adjacent
each extremity thereof; a series of links; a single
bar loop on one side of each link; double bar
hooks on the other side of each link, said single
bar loops being engaged in the offset portions
portion; and a pair of bar loops extending from
the other side of said body portion, said links
being bifurcated between said pair of bar loops
to form a sprocket tooth notch in said body
portion.
6. A link for Ibar conveyers comprising a rela
tively flat body portion; a bar loop extending
from the midportion of one side of said body 20
portion; and a pair of bar loops extending from
the other side of said body portion, said pair
being spaced-apart a distance suilicient to allow
an offset bar to pass longitudinally between the
pair of bar loops and the ñrst bar loop and on ~
each side of the latter.
7. A bar conveyer comprising: a series of round
parallel bars; a rectangular offset formed in each
bar adjacent each extremity thereof, said oifset
consisting of a short section of said bar forced ‘
to one side of the main section and connected
with the main section by short lateral bends;
a series of links; a single bar loop on one ex
tremity of each link; a pair of spaced-apart bar
loops on the other extremity of each link, said
single bar loops being engaged in the offset por
tions of said bars; and said pair of bar loops
engaging the main portions of said bars at each
side of said offset so that said bent portions will
separate the single bar loops from the pair of 40
bar loops.
