I, FRITZ CHONÉ, of No. 52, Ackerstrasse, Berlin, Germany, Engineer, do hereby
declare the nature of this invention to be as follows:-
The present invention relates to roller collectors for electric railways having
single or double lines.
The invention comprises particularly means for enabling the rollers or runners
of two cars running in opposite directions, to cross each other on one and the
same conductor wire.
In order to attain this result, the wire is advantageously mounted approxi-
mately in the centre above the two cars, and the roller rods of the said cars, are
bent round at the top at about right angles, so that the horizontal or approxi-
mately horizontal arm of the collector or roller arm of one car will lie on the
opposite side of the main conductor to that of the car running in the opposite
direction. Thus when the rollers of meeting cars meet on the single main con-
ductor one roller will roll underneath the other and reach the main wire again.
In order to prevent the rollers from slipping off the wire when one of the same
runs underneath the other, the rollers are both provided with guide grooves, and
projecting rims between the same so that the grooves of one roller will be guided
in the rims of the roller meeting it and thus the roller which leaves the wire and
passes below the one remaining against the wire, will be guided back on to the
wire again as soon as it has passed the other.
Or one roller may be made broader than the other and have lateral flanges
between which the narrow roller is guided whilst it passes under or over the
broader roller.
Yet another form of carrying the invention into practice consists in providing
the roll which remains on the main wire with a switch or incline or cam sur-
face, which extends from the under side of the wire in a slight incline to below
the upper roll and then runs upwardly to the wire. again, this switch being.
carried by one of the cars, whilst the other one which has to pass it is simply
provided with a roller which as soon as the cars meet, runs on to the switch and
is guided below the upper roll and back on to the main wire by the said switch.
In this case it is necessary that only one of the cars is provided with the switch.
The switch piece may be attached in any convenient manner to the axle of the
roll carrying it or to the top of the rod or at any other suitable point.
By means of the present invention the necessity for double overhead wires is
obviated and double lines of cars may run with one overhead wire.

page_text: I, FRITZ CHONE, of No. 52, Ackerstrasse, Berlin, Germany, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement;
The present invention relates to roller conductors for electric railways having
single or double lines.
The invention comprises particularly means for enabling the rollers or runners
of two cars running in opposite directions, to cross each other on one and the
same conductor wire.
In order to attain this result, the wire is advantageously mounted approxi-
mately in the centre above two cars, and the roller rods of the said cars are
bent round at the top at about right angles, so that the horizontal or approxi-
mately horizontal arm of the conductor or roller arm of one car will lie on the
opposite side of the main conductor to that of the car running in the opposite
direction. Thus when the rollers of meeting cars meet on the single main con-
ductor one roller will roll underneath the other and reach the main wire again.
In order to prevent the rollers from slipping off the wire when one of the same
runs underneath the other, the rollers are both provided with guide grooves, and
projecting rims between the same so that the grooves of one roller will be guided
in the rims of the roller meeting it and thus the roller which leaves the wire and
passes below the one remaining against the wire, will be guided back on to the
wire again as soon as it has passed the other.
Or one roller may be made broader than the other and have lateral flanges
between which the narrow roller is guided whilst it passes under or over the
broader roller.
Yet another form of carrying the invention into practice consists in providing
the roll which remains on the main wire with a switch or incline or cam sur-
face, which extends from the underside of the wire in a slight incline to below
the upper roll and then runs upwardly to the wire again, this switch being
carried by one of the cars, whilst the other one which has to pass it is simply
provided with a roller, which as soon as the cars meet, runs on to the switch and
is guided below the upper roll and back on to the main wire by the said switch.
In this case it is necessary that only one of the cars is provided with the switch.
The switch piece may be attached in any convenient manner to the axle of the
roll carrying it or to the top of the rod or at any other suitable point.
By means of the present invention the necessity for double overhead wires is
obviated and double lines of cars may run with one overhead wire.
The accompanying illustrations will render my invention more easily understood
and carried into practical effect.
Of these illustrations, Fig. 1 is a front view of the upper ends of two trolleys
arranged according to my invention with flanged rollers; Figs. 2 and 3 are a
side and front view respectively of a modified arrangement in which one trolley
carries a guide for the roller of the second to run over, and Figs. 4 and 5 are a front
and side elevation respectively of an arrangement in which the trolleys are
provided with flanged rollers of different widths.
As shewn in Fig. 1 the trolley rods a, b, of two cars have their
so bent that the rollers.e, f, carried by them will run upon the conductor
upper ends ", d,
is so supported as to occupy a position midway between the two lines upon which
9 which
the cars run. These rollers e, f, are each formed with a groove to receive the
conductor 9 and with three flanges h, i, o, & k, l, m respectively, which when said
rollers meet allow one roller to run over the other and so pass as shown.

page_text: With the arrangement shewn in Figs. 2 and 3 the trolley arms a, f, are bent
similarly as described in Fig. 1, but the rollers c, g, carried by them are of the
same size and width but are enabled to pass one another by the aid of a guide
piece b which which is carried by one arma and over which the roller g will travel
as the rollers pass. Figs. 4 and 5 shew a similar arrangement as in Fig. 1 but
the rollers a, b, which run on the conductor c, are of different diameters and
widths, so that one of said rollers may travel over the other when they are pass-
ing, and will be prevented from becoming, displaced by its flanges, as shown.
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:―
(1) In connection with overhead electric tramways, trolleys having their arms
bent so that the rollers carried by them may run upon a conductor supported
between two lines, such rollers being grooved or flanged so that when the two
rollers of two cars travelling in opposite directions, one upon each line, meet
they may pass by one travelling over the other substantially as described and
illustrated by Figs. 1 4 and 5 of the accompanying drawings."
(2) In connection with overhead electric tramways, trolleys having their arms
bent so that the rollers carried by them travel upon a conductor supported between
two lines, and carrying guides which, when the two rollers of two cars travelling
in opposite directions, one on each line, meet, they may pass by one of said rollers
travelling over such guide substantially as described and illustrated by Figs. 2
and 3 of the accompanying drawings.
