Improvements in the Construction of Motor Driven Vehicles.
We, WILLIAM SIMPSON of 8, Minshull Street, Cotton Manufacturer, WALTER LIGHT
BODMAN, of 28, Lower Moss Lane, Manufacturer, and DANIEL HARRISON SIMPSON of
28, Lower Moss Lane, Engineer, all of Manchester in the County of Lancaster do
hereby declare the nature of this invention to be as follows:-
This invention relates more particularly to the construction of the framework for
carrying the travelling wheels, motor, gearing, fuel vessels and generator or its
equivalent, and has for its object to obtain, firstly, a sufficiently rigid construction,
and secondly, to obtain freedom from vibration for the body or for the occupants of
the vehicle.
The improved framework consists of a perch to which the axles are directly attached,
and is built of metal tubing preferably steel. The joints, crossings and other
connections are made of any suitable metal, and may he of well known form.
Preferably, however, these connections are made in the form hereinafter described.
In the construction of this framework or perch, a rectangular frame of tubing is
formed, and extends over the centres of the wheel axles. A wing is formed on each
side by a bracket clipping the side of the frame and depending therefrom, and by the
extension of the end cross bar or other portion of the frame. There is also at each
side of and depending from each wing and from each side bar of the frame a bearing
bracket or bearing brackets in which is formed a bearing of the driving wheel axle or
axles and of parts of the motion or gear. The bearings and brackets are connected
together at their lower parts by longitudinal and transverse ties. Diagonal stays
connect the lower parts of the bearings and brackets with the end portions or end
bars of the rectangular frame.
Over the position to be occupied by the steering wheels axles or axletree, a single
or double diagonal stay connecting the end of the frame or perch with the cross stay
connecting the brackets at their lower parts, is fixed, and provided with a bearing
which carries the axle-tree or connecting bar of the steering-wheels axles, so
constructed that the axle-tree aforesaid can oscillate thereon and pernit of the
steering wheels passing over obstacles or depressions on the road without twisting the
frame or perch, which by this arrangement is supported upon three points, viz.:
the side bearings of the driving wheels and the bearing of the axle-tree. The steering
wheels axles are hinged near the hubs of the wheels, and are provided with arms
and connected together on the system known as Ackerman's.
Suitable seatings or brackets are provided on the percb or frame to carry the
springs. The body of the vehicle is mounted upon the springs and is tbus
independent of the motion or gear.
The before mentioned wings, brackets and bearings carry the motor and driving
gear.
The joints and connections hereinbefore referred to are formed with plain bored
sockets which are turned slightly conical and screwed upon the exterior, and are

page_text: slit or saw cut longitudinally. A conically bored and tapped sleeve is fitted to the
sookets and after the tube ends are inserted in the sockets, the sleeves are screwed
tightly on and cause the sockets to grip the tubes.

Improvements in the Construction of Motor Driven Vehicles.
We, WILLIAM SIMPSON of 8 Minshull Street, Manchester in the County of
Lancaster, Cotton Manufacturer, WALTER LIGHT BODMAN Manufacturer and DANIEL
HARRISON SIMPSON Engineer, both of Village View Burnage Lane, Didsbury in the
County of Lancaster, formerly of 28 Lower Moss Lane Manchester, 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 more particularly to the improved construction of the
framework for carrying the travelling wheels, motor, gearing, fuel vessels and
generator or its equivalent and has for its object to obtain first a sufficiently rigid
construction and secondly to obtain freedom from vibration for the body or for the
occupants of the vehicle."
This construction of framework is chiefly applicable to that system of construction
of motor vehicle in which the generator, motor and their necessary parts and
adjuncts are carried by an under frame or perch to which, wheels having spring or
cushion tyres or rims are attached and upon which the body of the vehicle is
supported by springs.
The improved frame work consists of a perch constructed as hereinafter described
to which the wheel axles are directly attached, and is built of metal tubing,
preferably steel. The joints, crossings brackets and other parts and connections are
inade of any suitable metal, for instance iron, steel or gunmetal, and may be of any
well known form or construction. Preferably however these parts and connections are
made to secure in position and grasp the tubes in the manner hereinafter described.
In order that our invention may be more readily understood we have attached
hereunto a sheet of drawings to which we will now refer.
The improved construction of perch described herein and illustrated in the said
drawings is also applicable to other systems of motive power than that of steam
indicated.
In the said drawings Figure 1 represents a side elevation of a motor driven vehicle
constructed in accordance with our improvements. Figure 2 is a half front elevation
and Figure 3 a half back elevation of the same. Figure 4 is a half plan of the
vehicle looking from the underside. Figure 5 is a view of the tube connecting
sockets or couplings we employ. In the several views similar parts are indicated by
similar letters of reference.
The framework or perch a consists of a rectangular trussed frame of steel tubing
formed with a wing b on each side and extends over the axial line through the wheel
centres. The tubing is formed into straight bars of suitable lengths and joined
together to produce the form of framing desired, by means of elbows, tees,
and cross connecting sockets and suitable brackets. These connecting pieces and
brackets are made of steel, malleable iron, gun-metal or other suitable metal and are

page_text: formed for securing to the tubes preferably in the manner hereinafter described.
But they may be formed with screwed sockets to receive screwed ends of the tubes
and where the tubes continue right through the sockets the latter are split along one
side and provided with lugs and screws by which they are clamped upon the tubular
bars.
Each wing b is formed by continuing the end bar e' past the side bar a carrying a
bracket depending and projecting from the bar a2 and connecting each end of the
said end bar with the bracket 1 by means of the bar b2 in each case. The brackets ¹
are connected together by the cross bar 63. Depending also from the bars a² are
bearing brackets a' and siinilar bearing brackets & depend from the bars . These
bearing brackets a bare connected to the depending brackets & by the hars and
the bars . The bearing brackets and carry the bearings of the crank shaft ;
they are also connected together by the tie rod or bar 6. Struts or stays be connect
the end bar with the lower parts of the said bearing brackets. There is a stay a
between the end bar and the cross bar 63. This is preferably formed of a single
steel tube but two parallel tubes or a solid metal single or double stay may be used.
Upon this stay is fixed or formed a journal and there is fitted a bearing d capable of
oscillating thereon, which bearing carries the steering wheels axle tree d¹.
The axle tree d carrying the steering wheels k is preferably formed of steel tubing,
to the ends of which are fitted short axles d by means of a knuckle joint d³. To each
axle d is fixed an arın d which is coupled with a sector d by means of a coupling
rod do with knuckle jointed ends d ds. The ends 7 of the coupling rods d cross
one another when jointed to the sector d as shewn in Figure 4. The sector is
mounted in a suitable bearing " and is connected to the steering rod in the steering
post o fixed to the body framework of the vehicle by means of the flexible
coupling which steering rod is operated by the hand wheel
suitable worn or bevil gearing. The body/ is shewn mounted upon
the springs y are seated upon the bearings brackets and the
upon a transverse bar g fixed to the side bars a² of the framing.

The axle tree d¹ is
are continued to meet
In some cases the end bar a' is prolonged and the bars
it. In this case additional diagonal stays not indicated in the drawings may connect
the lower part of the depending brackets & with the end bar a.
To the depending brackets are bolted the cylinders A which in the case
illustrated act upon the driving wheels directly the crank shafts c forming also the
driving wheels axles. When liowever the motor acts through gearing, the driving
wheel bearings are fixed above the centre shewn in Figures 1, 2, and 3 of the
drawings.
Referring now to Figure 5 which illustrates a view in section of a junction of two
tubes with a junction or tee piece formed in the manner herein before referred
to represents the body of the junction piece which is formed with sockets P
Each socket is externally formed slightly conical and is screwed and split longitudinally
as indicated by the saw ends . An internally screwed sleeve is formed to fit and
to screw on to the socket, by which when tubes fitting the sockets are passed
thereinto the sockets are caused to tightly grip the tubes by the screwing on
of the sleeves.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
First. The improved tubular construction of perch or underframe for motor driven
road vehicles which consists of a rectangular frame a composed of the longitudinal
bars the transverse bars as provided with wings b formed by the projecting
and depending brackets 1, the depending bearing brackets a3 64 for carrying
the driving wheels axles and crank shafts, the longitudinal bars a band
the diagonal stays connecting the bar a with the said bearing brackets
tie bars, and the diagonal stay e, provided with an oscillatory bearing d

page_text: carrying the axle tree d, such frame being provided with suitable seats g² for
connecting the springs g gl carrying the body of the vehicle and for attaching the
motor, generator and necessary parts thereof substantially as herein before described
and illustrated in the several figures of the drawings.
Second. In motor driven road vehicles in which the framework is constructed
chiefly of metal tubing, connecting and securing the tubes to the brackets, junctions,
elbows and to other tubes in the manner hereinbefore described and illustrated with
reference to Figure 5 of the drawings.
