Improvements in Trolley Carriages and Means for Driving the same.
I, JAMES HARTMAN TALBOT, of 182, Sullivan Avenue, Detroit, in the State of
Michigan, in the United States of America, Paving Contractor, 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:-
My invention relates to improvements in trolley carriages, and is shown in
the accompanying drawings in which:
Fig. 1 is an elevation of one form of the device.
Fig. 2 is a sectional view showing the trolley and its immediate driving
mechanism.
Fig. 3, is a detail showing the spring extension joint of the frame.
Fig. 4 is a view showing the support for the trolley wire.
Fig. 5, is an elevation of a second form of the device and
Fig. 6 is an end elevation of the form shown in Fig. 5.
In the drawings, a, is the trolley wire upon which the carriage travels, the
wire support preferably provided with a spring of sufficient tension to hold up the
wire until the carriage arrives directly over it, to relieve the sudden turning
of the carriage from one loop of the wire to the next. c, c are the upright
sections of the frame of the carriage. These end frames are preferably made
of bicycle tubing and are jointed, either by the spring extension joint l, shown
in Fig. 3 or by the use of the threaded sleeve d in the form shown in Fig. 5.
These vertical sections of the frame are united by suitable cross bars and braces.
With the upper ends of the vertical tubing are engaged the frames e e, in
which are mounted the trolley wheels ff, and their immediate driving
mechanism. The difference between the forms shown, consists in the means
employed for driving the trolley wheels. In the form shown in Fig. 1 a long
belt g is employed that passes around the frame over an idler h under the drive
wheel i, of the bicycle held in the frame, and over the driving pulleys jj.
The power is applied to the trolley wheels through sprocket wheels and the
chains as shown. To keep the belt on the driving wheel of the bicycle I employ
a guide frame and a series of small rolls k, k on each side of the wheel.
The spring extension joint 1, allows a part of the weight of the rider to be
thrown on the belt, to ensure the proper amount of friction.
In the form shown in Fig. 5, the driving wheel of the bicycle acts upon a
short driving belt m, which runs over the idler n and the driving pulley o.
From this pulley the power is applied to the trolley wheel at the rear end of
the frame, through the shaft p and suitable bevel gearing at each end of the
shaft.
The lower sections of the frame are bifurcated, and the forks arranged to go
over the bicycle wheels; in the case of the front wheel to embrace it to steady
it and in case of the rear wheel to allow the wheel to turn freely, but to provide
means from which to support the frame of the bicycle in a fixed position from
each side of the wheel. On the lower cross bars of the frame I mount a cradle g
in which to rest the front wheel of the bicycle.

page_text: To provide against the accidental disconnecting of the trolley wheels and
the wire, I employ small rolls underneath the wire to hold the wheels down
near the wire, either with, or without overhanging hooks to prevent the wheels
from moving sidewise and off from the wire. Such hooks may be made with a
latch so as to completely encircle the wire, except when passing the wire supports.
While I have shown my device as driven by a bicycle fixed in the frame, my
invention is not limited thereto as the driving mechanism may form a part of
the carriage and may be driven by the rider or by a prime motor.
Any suitable means may be employed to clamp the frame of the bicycle firmly
to the frame of the carriage and I show different forms of clamping devices.
The principal requirements of these devices are that they shall be so readily
adjusted that the bicycle can be attached to or removed from the frame quickly,
and that they shall be arranged to accomodate different styles of bicycles.
While I have shown the trolley mounted in a rigid frame I contemplate if
found desirable, an adjustable bearing for the wheels whereby they may more
readily adapt themselves to curves in the track or cable.
I also contemplate lining the clamps with rubber or other suitable material
to protect the enamel of the mounted bicycle from injury.
While a rectangular frame employing two uprights is shown, a single upright
and a single trolley may be used where a portable device is desired.
While in Fig. 5 driving power is applied to only one of the trolley wheels it
is apparent that it may be applied to both if found desirable.
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. A bicycle trolley, consisting of trolley wheels, a frame work adapted to
support said trolley wheels and to receive a bicycle, and means operated by said
bicycle for propelling said trolleys, substantially as described.
2. A bicycle trolley consisting of trolley wheels, a framework adapted to
support said trolley wheels and means under the control of the rider for propelling
said trolley, substantially as described.
3. A bicycle trolley consisting of a suitable framework, trolley wheels mounted
in said frame work, means for supporting a bicycle in said franie, and propelling
means connecting said bicycle with the trolley substantially as described.
4. A bicycle trolley consisting of trolley wheels, suitably mounted, a frame-
work adapted to receive a bicycle, means for propelling the trolley wheels and a
belt connecting the wheels of said bicycle with said means for propelling the
trolley wheels substantially as described.
5. A bicycle trolley consisting of a suitable framework, trolley wheels mounted
in said framework, a belt adapted to operate said trolley wheels and a driving
mechanism supported by and adapted to drive said belt, substantially as described.
6. A bicycle trolley consisting of a suitable framework, trolley wheels mounted
in said frame, suitable clamping mechanisms for securing a bicycle in the frame
and a belt adapted to drive said trolley wheels and to support and be driven by
said bicycle, substantially as described.
7. The combination of the bicycle, a trolley carriage adapted to support said
bicycle and means for propelling said trolley carriage operated by said bicycle,
substantially as described.
8. The combination of the trolley, a carriage adapted to transport one or
more persons, a belt suspended from said trolley arranged to support said
carriage and drive said trolley and means for driving said belt, substantially
as described.
9. The combination of the bicycle, a suitable framework to receive said bicycle,
trolley wheels mounted in said frame, a belt adapted to drive said trolley and
to support and be driven by the bicycle, and means for retaining said belt in
position under said bicycle wheels, substantially as described.
