1 Claim. (Cl. 173-324)
This invention relates to an adapter terminal
constituting an attachment for a self-starter of
an internal combustion engine of the type used
upon automobiles and other motor vehicles. Cer
tain types of motor vehicles have a self-starter .
system operated by depressing the gas pedal.
Figure 6 is a diagrammatic view showing the
adapter terminal applied for use.
This adapter terminal constitutes an attach
ment which is to. be applied to a self-starter, such
a self-starter being indicated in general by the
numeral l in Figure 6, and includes a built-in
knob which is liable to become broken or Worn
Other types of motor vehicles have a starter sys
out and thus render a self-starter of the type
tem which is operated by means of a button on
energized by pressure upon the gas pedal inop
the dashboard which closes a magnetic switch
generally known as a solenoid switch to complete 10 erative. This device has a casing 2 which is
a circuit and energize the starter. It sometimes
happens that in a starter system having a circuit
closed by pressure upon the gas pedal, the built'in
terminal of the starter will become broken, and
if necessary parts are not available, it is difficult
to make necessary repairs. Therefore, it is one
object of the invention to provide an attachment
which may be applied to the built in terminal of
a starter of the type actuated by pressure upon
the gas pedal and then attach to this terminal
a starter cable leading from a solenoid switch
which is energized by a button upon the instru
ment board of the vehicle. It will thus be seen
that a starter system including a built-in termi
nal actuated from the gas pedal may be very
easily converted into a system wherein a sole
noid switch is connected with a button upon the
instrument board of the motor vehicle and the
vehicle immediately rendered operative.
Another object of the invention is to provide
an attachment which includes in its construc
tion a casing adapted to be secured to a starter
formed of sheet metal and provided at opposite
sides with extensions or tongues 3 formed with
openings 4 through which fasteners 55 are passed
in order to ?rmly secure the casing in place upon
the self~starter l over and about the built in
knob of the self-starter. This knob has not been
shown in the drawing, as it is a portion of a
self-starter of conventional formation.
A cable 6 leading from a solenoid switch ‘i is
to be connected with the attachment so that
when a push button 8 on the instrument board
9 is pressed upon, a circuit will be closed from
the battery [0 to the self-starter. In order that
the cable 6 may be connected with the attach
25 ment, there has been provided a copper termi
nal post or bolt l I which passe-S through an open
ing l2 formed in the top of the casing. A flat
head I2 is formed at the lower end of the post
or bolt II and close to this head is formed a
30 squared shoulder I3 which passes through a
square opening l4 formed in a copper plate or
washer 15. Since the plate or washer I5 is square
and ?ts snugly between side walls of the casing,

Another object of the invention is to provide
