Improvements in Tipping Carts or Wagons and other Vehicles.
I, THOMAS HILL, of No. 48, Railroad Avenue, Jersey City, in the County of
Hudson, and State of New Jersey, United States of America, Wagon Builder, do
hereby declare the nature of this invention to be as follows:-
This Invention more particularly relates to tipping carts or wagons for cominon
road and other like use and the bodies of which are mounted on side trunnions; and
the invention consists in an elastic pedestal for said trunnions of special construction
also in an elastic buffer applied to control and support the forward portion of the
tilting body of the cart or wagon.
The body of the vehicle is preferably constructed of sheet metal and composed of
a bottom, a sloping back, an upright front, and sides. Said vehicle body is hung by
side trunnions supported in specially constructed bearings for the purpose of tilting
the body as required. Each of said bearings is supported on an elastic vulcanized
india-rubber pedestal composed of a cylindrical or other shaped upright body
socketed at its top to receive the shank of the metal bearing in which the trunnion
rests and provided at the bottom with an extended flat base or foot flange which rests
upon a seat on top of the upright part of the cranked axle. This rubber pedestal is
enclosed within a metal box shaped to receive snugly within it both the upright or
body part of the elastic pedestal and the top and sides of the base or foot flange. The
upper or body part of said metal box extends some distance above the elastic pedestal
and is preferably closed at top but is provided on its inner side with a vertical slot
through which the trunnion passes and which provides for the up and down play of
said trunnion. The lower portion of said metal box, which fits over the upper end
of the upright part of the cranked axle that the elastic pedestal rests upon, has cast
with or on it a mud guard that serves to exclude mud or dirt and the metal box or
upright, with its contained rubber pedestal, is firmly secured to the axle by bolts. The
metal box, closed at its top, is open below to admit of the insertion of the spring or
rubber pedestal with its bearing from beneath. By thus hanging the pivots of the
body of the vehicle upon an upright or pedestal which is composed of rubber and
has an extended rubber base, not only is an easier running action obtained for the
vehicle but the noise so common to such bodies, and, which is so objectionable, will be
largely done away with. If the cart axle be straight instead of cranked, the pedestal
and box will be mounted and secured by bolts upon the top of either shaft of the
vehicle instead of upon the top of the axle.
It should here be observed that the trunnions are arranged over, and in the same
centre plane of gravity as, the axle of the running wheels. By thus avoiding placing
them either forwardly or in rear of the wheel axle, the body of the vehicle being so
easily balanced will swing readily and discharge its load quickly.
In the pedestal which I have described, the spring is inserted from the bottom
thereby largely lessening the cost and the spring is thoroughly protected, being always
enclosed and having no movable cap. By providing, too, the rubber springs or
cushions with base flanges as described, jar or noise is materially lessened. This
part of my invention is also applicable to other vehicles, whether tilting or not, in
which the bodies have side projections or pivots arranged to similarly rest upon
springs, including tipping carts or wagons of various kinds.
Another feature of my invention which is also applicable to tipping carts or
wagons and other like tilting vehicles of different kinds and which I now proceed to
describe, consists in applying to the forward portion of the tilting body of the vehicle,
one or more elastic buffer devices preferably, constructed as hereinafter described.

page_text: The object and effect of these buffer devices is not simply to diminish shock on bring-
ing the forward portion of the tilting body down to its place but mainly to do away
with that jar and noise which is usually so especially noticeable and objectionable in
tipping carts or wagons, consequent upon the vibration of the tilting body when the
vehicle is in motion. Said front buffers or buffer devices might be secured to the body
of the vehicle so as to rest when the front portion of the body is down upon fixed
under-supports or projections from the shafts of the vehicle, but it is preferable to
attach them to the shafts and have the forward portion of the vehicle body come down
and rest upon them.
The elastic cushions, which might be composed of spiral wire or any other suitable
elastic material but which are preferably made of rubber blocks that may be of
cylindrical form, are arranged to project slightly above the level of the shafts. When
the forward portion of the vehicle body rests upon them, said cushions will be slightly
compressed the forward portion of said body being secured when down by a latch
engaging with a catch on the body or any other suitable fastening device may be
used. These rubber blocks are seated within metal socket pieces provided with flanges
which admit of said socket pieces being secured by screws or bolts to the insides of
the shafts of the vehicle and to a transom connecting said shafts. This forms a very
simple and efficient elastic buffer device for the purpose and one which can be easily
applied to almost any dumping cart, wagon, or vehicle, and the spring portions of
which can be readily renewed, when required.
When these or other equivalent elastic front buffer devices are combined with
elastic pedestals or springs to the side pivots of the vehicle, jar, noise, or rattle, will
be still further, and most effectually, prevented.

Improvements in Tipping Carts or Wagons and other Vehicles.
I, THOMAS HILL of No. 48, Railroad Avenue, Jersey City, in the County of
Hudson and State of New Jersey, United States of America, Wagon Builder, 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 more particularly relates to tipping carts or wagons for common
road and other like use and the bodies of which are supported by side pivots or
journals to provide for the tilting of them; and the invention consists in an elastic
pedestal for said pivots or journals of special construction, substantially as herein-
after described and pointed out in the claims, also in an elastic buffer applied to
control and support the forward portion of the tilting body of the cart or wagon, as
hereinafter more particularly specified and claimed.
Reference is to be had to the accompanying drawings, forming part of this specifi-
cation, in which figure 1 represents a side elevation of a tipping cart, embodying my
invention, with one of the wheels of the vehicle removed and shewing the cart as
provided with a cranked axle. Figure 2 is a similar view, shewing the body of the
wagon in position as when tipping its load. Figure 3 is a vertical transverse section,
in part, of said part, in illustration of a rubber pedestal with enclosing box or
upright in which the pivots or trunnions of the body of the cart are carried for the
purpose not only of giving elasticity to the body but to largely reduce the noise
which usually attaches to the tilting body of tipping carts having side pivots or
trunnions. Figure 4 is a perspective view of the box or upright which encloses
said pedestal. Figure 5 is a perspective view of the rubber pedestal detached.
Figures 6 and 7 are similar views to figures 1 and 2 but shewing the tipping cart as

page_text: provided with a straight axle and a different connection of the shafts of the vehicle
with the axle. Figure 8 is a vertical section, in a plane at right angles to figure 3,
of the rubber pedestal and its box, with axle in part. Figure is a view in
perspective of a portion of the shafts of the tipping cart with an elastic buffer device
applied thereto for controlling and supporting the forward portion of the tilting body
of the cart and figure 10 is a perspective view, upon a larger scale, of said buffer
device which is represented as partly broken away.
Similar letters of reference indicate corresponding parts in all the figures.
Referring in the first instance or more particularly to figures 1, 2, 3, 4, and 5, of
the drawings, A is the body of the vehicle preferably constructed of sheet metal and
composed of a bottom, a sloping back, a front, and sides. Said vehicle body is hung
by opposite side pivots or trunnions 6, one only of which is here shewn, fast on a
body frame c in specially constructed bearings, substantially as hereinafter described,
for the purpose of tilting the body as required. Thus, mounted on each upright
arm of the cranked axle B carrying the arm 7 on which the vehicle wheel turns, is
an elastic vulcanized india rubber pedestal C for either pivot or trunnion b of the
body and which is composed of a cylindrical or other shaped upright body socketed
to receive the shank of a metal bearing d at its top in which bearing the pivot b
rests and constructed at the bottom with an extended flat base or foot flango e which .
rests upon a spread portion or seat on top of the axle. This rubber pedestal is
enclosed within a metal box or upright D shaped to receive snugly within it both the
upright or body part of the elastic pedestal and the top and sides of the base or foot
flange e. The upper or body part of said metal box D extends some distance above
the elastic pedestal C and its pivot bearing d is preferably closed at its top but is
provided on its inner side with a vertical slot f through which the pivot or trunnion b
passes, and which provides for the up and down movement of said pivot as the elastic
pedestal moves or yields. The lower portion of said metal box D, which fits over
the upper end of the axle B that the elastic pedestal C rests upon, has cast with or
on it a mud guard g that serves to exclude mud or dirt and the metal box or
upright with its contained rubber pedestal is firmly secured to the axle by bolts h.
The metal box D closed at its top is open below to admit of the insertion of the
spring or rubber pedestal with its bearing d from beneath. By thus hanging the
pivots of the body of the vehicle upon an upright or pedestal which is composed of
rubber and has an extended rubber base, not only is an easier running action
obtained for the vehicle but the noise so common to such bodies and which is so
objectionable will be largely done away with.
In figures 6 and 7 of the drawings, the same construction of an elastic support
for the pivots of the tilting body of the vehicle is shewn including the rubber
pedestal C and its enclosing box D but, in these views, said parts are represented as
adapted to a tipping cart having a straight axle B' instead of a cranked one,
in which case said parts will be mounted and secured, as shewa, by the
bolts upon the top of either shaft S of the vehicle instead of upon the top of
the axle.
It should here be observed that the pivots or trunnions b are arranged over and
in the same centre plane of gravity as the axle of the running wheels. By thus
avoiding placing them either forwardly or in rear of the wheel axle the body of the
vehicle being so easily balanced will swing readily and discharge its load quickly.
This arrangement, however, of the pivots of the body over the axle is not here claimed
as new in itself.
In the pedestal which I have described the spring is inserted from the bottom,
thereby largely lessening the cost and the spring is thoroughly protected being always
enclosed and having no movable cap. By providing, too, the rubber springs or
cushions C with base flanges as described, jar or noise is materially lessened. This
part of my invention is also applicable to other vehicles whether tilting or not in
which the bodies have side projections or pivots arranged to similarly rest upon
springs, including tipping carts or wagons of various kinds.
Another feature of my invention, which is also applicable to tipping carts or wagons

page_text: and other like tilting vehicles of different kinds and which 1' now proceed to describe
consists in applying to the forward portion of the tilting body of the vehicle one or
more elastic buffer devices, preferably constructed as hereinafter described. The
object and effect of these buffer devices is not simply to diminish shock on bringing
the forward portion of the tilting body down to its place but mainly to do away with
that jar and noise which is usually so especially noticeable and objectionable in
tipping carts or wagons consequent upon the vibration of the tilting body when the
vehicle is in motion. Said front buffers or buffer devices might be secured to the
body of the vehicle so as to rest, when the front portion of the body is down, upon
fixed under supports or projections from the shafts of the vehicle but it is preferable
to attach them to the shafts and have the forward portion of the vehicle body come
down and rest upon them.
Referring to the drawings and more particularly to figures 9 and 10 thereof,
G G indicate elastic cushions which might be composed of spiral wire or any other
suitable elastic material but which are preferably inade of rubber blocks that may be
of cylindrical form and which are arranged to project slightly above the level of the
shafts S to receive the forward portion of the vehicle hody A down upon them when
said cushions will be slightly compressed, the forward portion of said body being
secured when down by a catch & engaging with or over a projection c¹ of the body or
any other suitable fastening device may be used. These rubber blocks G G are
seated down within metal socket pieces H H provided with flanges d' d' which admit
of said socket pieces being secured by screws or bolts to the insides of the shafts S of
the vehicle and to a transom el connecting said shafts. This forms a very simple and
efficient elastic buffer device for the purpose and one which can be easily applied to
almost any tipping cart, wagon, or vehicle, and the spring portions of which can be
readily renewed when required. When these or other equivalent elastic front buffer
devices are combined with elastic pedestals or springs to the side pivots of the
vehicle, jar noise or rattle will be still further and most effectually prevented.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. In a tipping cart or other vehicle having its body carried by side pivots or
projections, an elastic rubber pedestal for said pivots or projections composed of an
upright body part and an extended yielding base or foot flange, substantially as
specified.
2. In a vehicle, the elastic rubber pedestal Chaving an extended base or foot
