I, CHARLES DINSMOOR of 800 Water Street, Warren in the County of Warren and
State of Pennsylvania, United States of America Attorney-at-Law, do hereby declare
the nature of this invention to be as follows:-
This Invention relates to the running gear of those classes of vehicles that run on
wheels and axles or rollers, as distinguished from sleighs. The object of my Invention
is to obviate, as far as possible, the jolt, strain, friction, and the difficulty of propulsion
that are inherent in the class of vehicles having for their running gear wheels and
axles, and to obtain a smooth and easy movement of the vehicle.
The Invention consists of endless chains of anti-friction rollers, encircling and
running around endless guide ways or rails formed on the side frames of the vehicle,
the rollers being enclosed by endless chains of guard shoes. The guide-ways or rails
are in vertical planes and oblong in form, being composed of upper and lower
horizontal members united by curved ends, and are grooved or flanged to prevent the
endless chains of rollers running off them. The guard shoes are jointed together,
and their side flanges enclose the rollers and embrace the guide ways or rails. They
rest on the ground, the rollers run in them, and the lower members of the guide ways
or rails rest on the.rollers.
As the vehicle is drawn along the ground the contact of the endless-guards with the
ground will cause the endless rails supporting the body of the vehicle to be drawn
along the endless chains of rollers, which at the same time pass around the endless
guide-ways or rails over which they run with but little friction, so the vehicle will not
only be easy running but, owing to the broad surface in contact with the ground, it
will be very easy riding.

page_text: I, CHARLES DINSMOOR of 800 Water Street Warren in the County of Warren and
State of Pennsylvania United States of America, Attorney-at-Law 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:-
This Invention relates to the running gear of those classes of vehicles that run on
wheels and axles or rollers as distinguished from sleighs.
The object of my Invention is to obviate as far as possible, the jolt, strain, friction,
and the difficulty of propulsion that are inherent in the class of vehicles having for
their running gear wheels and axles; to dispense with the use of springs; and to
obtain a smooth and easy movement of the vehicle. These objects I accomplish by
substituting for the wheels and axles endless and flexible or jointed tracks having
anti-friction rollers on which the body of the vehicle is supported by oblong side
pieces around which the endless tracks move from contact with the ground while the
vehicle is in motion. The outer surfaces of the oblong side pieces are grooved or
flanged, or otherwise constructed so as to hold the endless tracks and anti-friction
wheels in place, and the endless tracks may be constructed with guards linked together
to exclude dirt and other obstructions.
The Invention also consists in the peculiar construction and arrangement of parts,
as hereinafter fully described and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification in which Figure 1 is a sectional side elevation of my new and improved
vehicle; figure 2 is a transverse sectional elevation of the same on the line X-X
figure 1. Figure 3 is a perspective view of one of the guard links. Similar letters
of reference indicate corresponding parts in all the figures.
A A represent the endless tracks composed principally of the anti friction rollers a a
linked together by the jointed connecting links bb thus forming endless chains of
rollers. BB represent the side pieces of the body of the vehicle. These are oblong
in form and are held parellel with each other by suitable frame work C C which also
supports the body D between the said side pieces B B. The edges or surfaces of the
side pieces B B are flanged, as shewn at d d which flanges form guides for the wheels
of the endless tracks A A to run in, thus obviating all danger of lateral displacement
of the endless tracks. A' A' represent the guards surrounding the anti-friction
wheels a a.
These guards are made up of links preferably of sheet metal, formed as
shewn in Figure 3, each link having side flanges f¹ and a bottom plate f³, the links
being hinged together to form a continuous chain to enclose the anti-friction wheels a a,
as shewn clearly in figures 1 and 2. The ends of the flanges f¹ flare bevelled to
prevent the links from binding one with another as they pass around the ends of the
side pieces B B. The side flanges f1 f¹ are of such width relatively to the diameters
of the anti friction wheels a a, and the width of the flanges dd, that the edges of the
side flanges f¹ receive the flanges d between them, as shewn clearly in figure 2, so
that there is no danger of lateral displacement of the guards A². E represents thills,

page_text: or a pole attached to the vehicle by a strap E¹, and by which the vehicle may be drawn
by a horse or team. As the vehicle is drawn along the ground, the contact of the
endless guards A¹ with the ground will cause the body of the vehicle to be drawn
along the endless tracks as it were upon the oblong side pieces B, the latter running
upon the rollers a a. The endless tracks at the same time pass around the side
pieces B, over which they run with but little friction, so the vehicle will not only be
easy running but, owing to the broad surface in contact with the ground, it will be
very easy riding.
Having now particularly described and ascertained the nature of the said Invention,
and in what manner the same is to be performed, I declare that what I claim is ;
1. A vehicle, consisting of two endless tracks composed of anti-friction wheels
linked together, a suitable frame supporting the body D, and two oblong side pieces B
which support the frame and body upon the endless tracks, substantially as described.
2. The oblong side pieces B supporting the frame and body of the vehicle, in
combination with the endless tracks A of anti-friction rollers and the guard A' formed
of linked sections surrounding the endless roller tracks, substantially as and for the
purposes set forth.
3. An improved vehicle, consisting of the oblong frame B, C, having guide-ways
in its side pieces, a series of wheels a connected together by links b, guards A¹ hinged
together to form a continuous chain, the body A supported upon the frame between the
endless track, and the tongue or thills E connected to the said frame, substantially as
herein shewn and described.
'
4. In a vehicle, the combination with the frame B, C, and a series of wheels a
journaled in the connecting links b, of a track consisting of a series of hinged links f
each having bevelled side flanges fi and a bottom plate f³, the said track enclosing the
said wheels and moving the same by frictional contact, substantially as herein shewn
and described.
