PROVISIONAL SPECIFICATION.
Improvements in Oar Trucks,
I, CHARLES WALLACE HUNT, of Barker Street, West New Brighton, in the
State of New York, United States of America, Manufacturer, do hereby declare
the nature of this invention to be as follows:-
-
Car wheels have been made with flanges to come outside the track rails and
with conical treads, the larger diameters of the treads being distant from the
flanges so as to come inwardly, and with wheels thus constructed and mounted 'in
pairs on axles the axle boxes have been between the wheels, and provided with
suspending links that connect the axle boxes with the car frame.
I place the car or truck frames and axle boxes outside of the wheels and prolong
the axles into the boxes and provide suspending links between the axle boxes and
the frames for carrying the weight of the frames and the load thereon, so that the
weight will tend to restore the links to a vertical position, but the links allow the
parts to swing as the car is moving on a curved track, and the axle boxes being
outside the wheels there is sufficient leverage by the weight acting through the
pendant links upon the axle boxes and axle, to maintain the axle and wheels in
their proper relation to the track, whether travelling upon a straight or upon a
curved track, whereas in cases where the suspending links and frames come between
the wheels, there is not sufficient leverage of the weight acting through the
suspending links to hold the axle and wheels in their proper relation to the frame of
the truck or car. Hence the present improvements enable me to simplify the
device heretofore used and render the same more reliable and effective.

COMPLETE SPECIFICATION.
Improvements in Car Trucks.
I, CHARLES WALLACE HUNT, of Barker Street, West New Brighton, in the
State of New York, United States of America, Manufacturer, do hereby declare
the nature of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement, reference
being had to the accompanying drawings and to the letters and figures marked
thereon, that is to say:
Car wheels have been made with flanges to come outside the track rails, and with
conical treads, the larger diameters of the treads being distant from the flanges
so as to come inwardly, and with wheels thus constructed and mounted in pairs on
axles, the axle-boxes have been-between the wheels, and provided with suspending
links that connect the axle boxes with the car frame.
I place the car or truck frames and axle.boxes.outside of the wheels, and prolong

page_text: the axles into the boxes and provide suspending links between the axle boxes and
the frames for carrying the weight of the frames and the load thereon, so that the
weight will tend to restore the links to a vertical position; but the links allow the
parts to swing as the car is moving on a curved track and the axle boxes being
outside the wheels there is sufficient leverage by the weight acting through the
pendant links upon the axle boxes and axle, to maintain the axle and wheels in their
proper relation to the track, whether travelling upon a straight or upon a curved
track, whereas in cases where the suspending links and frames come between the
wheels, there is not sufficient leverage of the weight acting through the suspending
links to hold the axle and wheels in their proper relation to the frame of the truck
or car. Hence the present improvements enable me to simplify the device
heretofore used and render the same more reliable and effective.
In the drawings :—
Fig. 1 is a front end elevation; and Figs. 2 and 3 are side elevations representing
the suspending device and the frame outside of the car wheels.
Fig. 4 represents a modified form of suspending link.
Fig. 5 is a plan and Fig. 6'a section of the improvement where a triangular
frame is added.
The car-wheels B are upon the axle C, and such car-wheels are conical with the
larger diameter of the conical tread inwardly, and the flanges of the wheel are
outside of the rails.
The car-frame may be of wood or metal. I have represented it as of metal, and
the axle-boxes D are upon the outer ends of the axle C, and the frames A are
outside of the wheels, and they are provided with suspending links I to the cross-
bar above the axle-boxes D, and springs may be introduced, as at G, or not,
as desired, and there may be pairs of links I, as shown in Fig. 2, and the pairs of
links may be brought together in a V form to the bolt K, as shown in Fig. 3.
When the weight is suspended by the links I and the frames A are below the
axle-boxes D, the weight will tend to restore the links I to a vertical position; but
the links allow the parts to swing as the car is moving on a curved track, and the
axle-boxes being outside the wheels B there is sufficient leverage, by the weight
acting through the pendant links upon the axle-boxes and axle, to maintain the
axle and wheels in their proper relation to the track, whether travelling
upon a straight or upon a curved track, whereas in cases where the suspending
links and frames come between the wheels there is not sufficient leverage of the
weight acting through the suspending links to hold the axle and wheels in their.
proper relation to the frame of the truck or car. Hence the present improvements
enable me to simplify the device heretofore used and render the same more reliable
and effective.
The suspending links I may be forked at the lower ends so as to receive the
frames between the forks as seen in Fig. 4, to lessen the risk of the links being
bent by lateral strain.
In cases where a king bolt Ę is provided, it is to be above the centre of the axle
and connected with a bearer or sleeve D' over the axle and between the wheels B,
as illustrated in Figs. 5, 6, and this king bolt may be at the apex of the triangular
frame F that is connected to the frame A by the cross bolt or hinge G'. In this
case the king bolt prevents end motion of the axle and lessens the risk of injury to
the links I and ensures a uniformity of movement at each end of the axle as the.
parts swing in going round a curve.
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 :
1. The combination with the axle and car-wheels having outside flanges, of
axle-boxes at the outer ends of the car-axle and outside of the wheels and
connections between the boxes and frame outside the car-wheels, substantially as.
set forth.

page_text: 2. The combination with the axle, of car-wheels having flanges at their outer
faces, conical treads with the larger portions of the cones inwardly, car or truck
frames outside of the wheels, axle-boxes on the outer ends of the axles, and links
between the frame and the axle-boxes for allowing the axles to swivel, substantially
as set forth.
3. The combination with the car-wheels having outside flanges and an axle and
the frame passing outside the car-wheels, of a sleeve or bearer upon the axle
between one wheel and the other, a cèutral king bolt and a connector receiving the
king bolt at one end and attached at the other end to the car-frame, substantially
as set forth.
4. My improvements in car-trucks substantially as herein described; and shown
in the drawings.
