Improvements in or relating to Frames for Motor Road and other
Vehicles.
I, ALEXANDER MACKENZIE, of 27, Walnut-tree Walk, Kennington Road, in the
County of London, Coach-Builder, do hereby declare the nature of this invention
to be as follows;―
This invention relates to vehicle frames, and especially to those for use in self-
propelled vehicles, the object being to obtain accommodation, elastic or otherwise,
so that the frame will adapt itself independently of or in addition to the accom-
modation provided by the springs to inequalities in the road surface.
I will describe my invention as applied to a vehicle having four wheels, but it
is to be understood that the same invention may be employed with a greater or
less number of wheels, and. that the actual shape of the frame may vary accord-
ingly without departing from the spirit of the invention.
In a four-wheeled vehicle I have two axles, one of which serves as the steering
axle and has the wheels carried on ends pivotted to it. Two side frames either
straight or suitably curved or shaped extend so as to connect the two axles, the
axles themselves either passing through tubular portions one at each end, or being
otherwise in any convenient manner connected with these side frames or perches;
either axle may be fixed or may rotate.
At the connection of the front end of the side frame or perch with the front
axle, or should that rotate, with the tubular or other frame portion which carries
it, the side frame terminates in a sleeve or socket through which the axle cr
frame portion passes, so that the movement around the axis is allowed. Such a
connection may be employed to both the front ends of the side frames, if desired.
At the back end the side frame terminates in a bearing in any suitable part
of the back frame, back axle or bearing, but preferably in the bearing, so as to
allow of the back axle turning about the pivot upon the back end of the frame, so
that without disturbing that portion of the frame the axle can assume a position
other than horizontal by turning upon the frame. In connection with this pivotted
bearing I may or may not employ a clip, casing or other arrangement by which
the side frame can turn upon the axle in addition to the axle turning upon the
frame; preferably I arrange these two swivel or compensating bearings one on one
side in the front and the other on the other side at the back; I may employ four
of them where a rectangular or equivalent shaped frame is employed.
Ball-bearings may be employed wherever required.
In order to strengthen the side frames and their connection with the front axle
or frame, I employ preferably one curved framing piece secured to the side frames
at a suitable distance from the front axle or frame and to the front axle or
rame at the centre, a swivel or adjustable joint being employed so as to permit
of the swivelling or other employment of the front axle in relation to the frame.
This joint may be either a double or single swivel as required.
In a modified form the frame comprises at or towards the centre of its length a
حية

page_text: single tube or other frame having branching ends so as to take the ends of the
axles. These ends may be connected by swivel joints similar to those already
described or at least performing similar functions. The central frame may be
carried forward to the centre of the front axle where it may joint it by a single
or double swivel joint or connection.
At the back, one or both of the ends of the frame may be connected with the
bearings or other shaft carriers by swivel joints similar to those previously
described, or by universal or cup joints. Where desired bars or other supports
may be connected to the axle or to the back frame .and to the divided or forked
portion from the central frame so as to provide a support for the motor or gearing
of the vehicle.
Improvements in or relating to Frames for Motor Road and other
Vehicles.
I, ALEXANDER MACKENZIE, of 27, Walnut-tree Walk, Kennington Road, in the
County of London, Coach-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 relates to vehicle frames, and especially to those for use in self-
propelled vehicles, the object being to obtain accommodation, elastic or otherwise,
so that the frame will adapt itself independently of or in addition to the accom-
modation provided by the springs to inequalities in the road surface.
It is intended in this Complete Specification to limit the invention described in
the Provisional Specification to the joint by which the vehicle frame is attached
to the axle.
In the accompanying drawing the plumber-block A, which is adapted to receive
one of the axles of the vehicle, is provided with an extension B which receives
the end C of one of the members of the vehicle frame. The end C is screw.
threaded and is passed through the extension or socket B at right angles to the
axle of the vehicle. The threaded portion of the part C is of sufficient length to
permit the length passed through the part B to be adjusted. On the part C and
on either side of the socket B are arranged nuts D D', respectively.
nuts D D¹ are not screwed tightly against the socket B, but are adjusted in such
a manner that the part C of the frame is free to turn in the socket B.
The
It will be understood that the part A need not necessarily receive a revolving
axle but may carry a fixed axle.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is;-
1. In a vehicle frame the employment of a joint comprising a part such as A
secured to one of the axles of the vehicle or forming a bearing therefor and pro-
vided with an extension or socket B adapted to receive the end of one of the
members of the frame which is free to turn in the socket substantially as
described.
2. In a vehicle frame having a joint of the kind described securing the end of a

page_text: member of the frame in a socket such as B and with adjustable nuts substan-
tially as and for the purpose described.
3. In a vehicle frame the combination with the road wheel axle of a bearing-
joint which allows the frame-member such as C to partially rotate in relation to
the axle substantially as described and illustrated in the accompanying drawing.
4. The complete joint for a vehicle frame substantially as described and illus-
trated in the accompanying drawing.
