Improvements in Frames for Motor Tricycles.
I, BORIS LOUTZKY, of 49, Französische Strasse, Berlin, in the Empire of Ger-
many, Engineer, do hereby declare the nature of this invention to be as follows:-
-
in motor tricycles as hitherto constructed the motor is usually placed behind
the rear axle and thus the weight is too far back and too much taken off the front
wheel so that at times this latter is lifted off the ground thus rendering steering
impossible. In cases where the motor is placed in front of the rear axle access
to the motor is rendered difficult.
By means of the arrangement hereinafter described however I overcome the
above difficulties by so constructing parts of the cycle that they can be discon-
nected and folded over, thus giving free access to the motor.
In a tricycle with motor arrangement according to my invention, the rear-stay
is capable to be disconnected from the axle and turned upward. By disconnecting
the stays and the main bearing of the motor the whole of the rear part of the
machine including the rear-wheels may be removed; or after disconnecting the
motor bearing only the frame can be swung upward and thus afford ready access
to the motor. It is obviously advantageous to support the motor by suitable
means so as to relieve the strain on the bars.
The invention may be carried into effect in various forms, but it is preferable
not to connect the parts of the frame rigidly together as heretofore, but to con-
struct them so as to be capable of being swung round on pivots, when required,
and thus afford free access to the motor.

I, BORIS LOUTZKY, of 49, Französische Strasse, Berlin, German Empire, Engineer,
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:

to the motor is rendered difficult.
By means of the arrangement hereinafter described however I overcome the
above difficulties by so constructing parts of the cycle frame that they can be dis-
connected and folded over thus giving free access to the motor.
In the accompanying drawing
Figure 1 is an elevation of one form of frame constructed in accordance with
this invention,
Figure 2 is a plan of the same, and
Figure 3, 4 and 5 indicate diagrammatically the manner of disconnecting the
frame.
As may be seen the parts of the frame are capable of being swung upon pivot
pins.
Figures 1 and 2 show a complete tricycle with motor arrangement, and Figure 3
indicates how the rear stay a may be disconnected from the axle and turned
upward. By disconnecting the stays a and the main bearing e of the motor as
indicated in Figure the whole of the rear part of the machine including the
rear wheels d may be removed; or after disconnecting the motor bearing only the
frame can be swung upward as in Figure 5 and thus afford ready access to the
motor M. It is obviously advantageous to support the motor by suitable means so
as to relieve the strain on the bars e.
After having cleaned and repaired the said motor the parts of the frame are
again connected together.
The figures of the drawing show the motor suitably located within the triangular
portion formed by the three rear bars of the frame. The frame portion may then
be swung upward by first disconnecting the co-acting bars forming such triangle.
The invention may be carried into effect in various forms the parts of the frame
being constructed so as to be capable of being swung round on pivots or removed
when required and thus afford free access to the motor.
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. A frame for motor tricycles with the motor located between the 'wheels
arranged to swing or to be removable so as to afford free access to the motor,
substantially as described.
2. A form of frame of the type claimed in Claim 1, in which the motor is placed
between two portions of a triangle formed by the frame, such portions being
rendered capable of revolving about a common axis, substantially as described.
3: A frame of the type claimed in Claim 1 having the connecting rod a arranged
rotatably, for the purpose of making, accessible the motor, substantially
described.
