Improvements in Wheeled Vehicles.
I, THOMAS HILL, of 48-54 Railroad Avenue, Jersey City, in the State of
New Jersey, in the United States of America, Waggon Maker, do hereby
declaro 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 that portion of a wheeled vehicle especially of a kind
suited for tipping which includes the main frame or shafts, the axle supports and
the pedestals which carry the body of the vehicle.
The main objects of the invention are to combine lightness, durability and
strength, also easy or light running of the vehicle free from rattle or shake.
In the accompanying drawings shewing parts of a vehicle according to my
invention,
Fig. 1 is a plau partly in section upon the lines 1-1 in Figs. 3 and 4.
Fig. 2 is an elevation partly sectional upon the line 2-2 in Fig. 1.
Fig. 3 is a side elevation.
Fig. 4 a vertical section upon the line 4-4 in Fig. 1.
Fig. 6 is an elevation partly sectional on the line 5–8 in Fig. 6, showing a
modified construction of certain portions.
Fig. 6 a sectional side view of the same on the line 3-3 in Fig. 1; and
Fig. 7 is a vertically central section, shewing a modified construction of the
pedestal portion of the invention.
Referring in the first instance to the first four figures of the drawings,
AA indicate the side pieces of the main frame, which may be extended in front to
form the shafts of the vehicle. Each of these side pieces A A, passes through a
close fitting body B of a socket casting B B', which virtually forms a part of the
main frame. The body part B is of square section to hug the sides, top and bottom
of the side piece A, and it has on its underside at its one end, extended for the
purpose, a bracket like projection b preferably of greator width than the body and
having a recess c on its under face to receive within it the end of a cross-bar or
brace C, which connects the two castings B B and side pieces A A. Each
casting B has also a recess d on its under face to receive within it, the upper
portion of the axle D double or suitable U-shaped bolts e holding the axle within
the recesses d. These bolts are extended upwards through the body parts B of
the castings and through the side frame pieces A, and are provided with nuts
which hold the castings B firmly to the said pieces A, and hold the axle C beneath.
The castings B B', are further held to their place and the brace C secured to the
brackets b, by a bolt g arranged to pass up through the brace, through the body
part B of the casting and through the side piece A of the frame. Other bolts h
are also passed up through the brace C and each bracket b.
Upon the exterior side of each casting B B' is a mud shield i.
The upper part B' of each casting B B', being integral with the body part B,
requires no separate bolts or fastenings. This part B forms a hollow laterally
slotted pedestal, holding a spring & to support the body of the vehicle by a wrist
pin or trunnion, on each side of the body, arranged to pass through the vertical
slot, in the inner side of each pedestal. These pedestals differ from previous
constructions in several important respects. Thus each pedestal has its vertical
side slot / open above, and each wrist pin or trunnion of the vehicle body works
within an aperture m in an upright box or bushing E forming a bearing for the
Furthermore, this box or bushing E is integral with a
trunnion.
-
cap or cover n. to

page_text: the open-topped pedestal, thereby making the one casting serve both as the
trunnion bearing and pedestal cover. The box, bushing or bearing E is fitted to
enter freely down within the pedestal and has vertical slots c'e¹ in opposite sides of
it within which pass set screws d' d¹ which may be applied as shewn to the pedestal
to prevent the bearing or box from working out of the pedestal, yet permitting of
its easy play up and down. This construction of the pedestal and its cap or
cover and box or bearing E not only simplifies construction, but, on slackening
the set-screws d' d' so as to disengage them from the slots co', the body of the
vehicle may be readily lifted from the pedestals and the box or bearing E. and
bearing springs & can be conveniently detached for repair or otherwise.
In Fig. 7 I shew the capped pedestal box E as having only a single slot c', which
is made to pass entirely through it and instead of the set screws d', I pass a bolt aª,
having a nut on its one end, through the pedestal and through the slot e'. This
construction equalizes pressure and prevents lateral tilting of the pedestal capped
box in any direction, also prevents expansion of the open-topped portion of the
pedestal under heavy weight, shock or pressure.
Such pedestals and boxes or bearings give an easy rising and falling olnatic
support to the vehicle body, and in case of the vehicle being a tipping cart,
provide for the tipping or tilting of the body end wise.
The pedestal portions B' are sot inclining relatively to the body parts Bof_the
castings B B', or in other words, the longitudinal axis of each body part B inclines
upward in a forward direction while the vertical axis of each pedestal occupies an
upright position and forms a slightly acute anglo to the longitudinal axis of the
body part B on its front side, so that when the shafts or frame are raised out of a
horizontal position, as they usually are when draft is applied to the vehicle, the
pedestals still remain upright and thus secure an easy rising and falling motion,
free from side friction or binding, to the bearings or boxes E and their springs
and consequently give a more free elastic support to the vehicle body and its axle.
In Figs. 5 and 6 substantially the same construction is shewn as in the previous
figures, excepting that the body part B of either casting B B', is made of circular
form in transverse section at its ends and screw threaded internally to receive
within it the screw threaded ends of a transversely divided or sectionally con-
structed round side frame piece A, the sections composing which may either be
solid or tubular.
'Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a wheeled vehicle the combination of the axle D, the side shafts or frame
pieces 4A, the tubular pedestal castinga B B' having brace carrying brackets b
the U-shaped or clip-like axle supporting bolts e, the brace C, and the bolts g h,
substantially as specified.
2. The combination with the open topped pedestal having a vertical slot in
its inner side, opening upward through the pedestal, of a cap or cover to the
pedestal constructed to also form a box or bearing integral with the cap and free
to move up and down within tho pedestal, substantially as set forth.
3. The combination with the capped pedestal box and pedestal, of the longi-
