Lewis, Canton, Miss., assignor of ?fty per cent to George B. Herring, Canton, Miss. Application August 13, 1945, Serial No. 610,623 1 Claim. (Cl. 173-324) 1 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. 2 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, it Will be prevented from turning, and since the ried by the casing in such position that it will bolt or post has a squared shoulder passing bear against the built-in terminal, the post pro through a squared opening in this washer, the iecting outwardly from the casing so that a bolt will be prevented from turning. A liner it starter cable leading from a solenoid switch may formed of insulating material ?ts within the cas be connected to it. ing against the top and side and end walls thereof, Another object of the invention is to provide as shown in Figure 3, and serves very effectively an attachment which is very simple in construc 40 to prevent contact of the copper washer with the tion, cheap to manufacture, and capable of be casing and formation of a short circuit. After ing easily and quickly installed when necessary the bolt has been passed upwardly Or outwardly to convert a starter actuated by a gas pedal into through the opening in the top of the casing, a a starter actuated by a button upon the instru washer ll formed of insulation is applied about 45 ment board. the bolt and a metal washer 18 then applied so The invention is illustrated in the accompany that it rests upon the insulating washer H and ing drawing, wherein: protects the same from wear when a nut I9 is ap Figure 1 is a top plan view of the improved plied and tightened.

When the attachment is applied to the self Figure 4 is a bottom plan view of the adapter starter, the head at the inner or lower end of the terminal. 55 post I l bears against the built in knob of the self Figure 5 is a view looking at one end thereof. over a built-in terminal and a terminal post car 3 2,407,611 4 starter and since the solenoid switch 1 is con nected with the post by the cable 6 and with the battery It], pressure upon the push button switch pose the casing in enclosing relation to a built in knob of the starter, a liner of insulating mate rial ?tting snugly in said casing against the top 8 will close the circuit through the self-starter and walls thereof, a threaded post of conductive material passing through an opening in the top and cause operation of the self-starter. It will thus be seen that by use of this attachment, a self-starter of the type energized by pressure of said casing and having a head at its inner end upon the gas pedal and having its built in knob for engaging the knob of the starter, a washer It is thought that persons skilled in the art to which the invention relates will be able to obtain ing to prevent rotation of the washer and said post having a squared shoulder adjacent its head passing through a squared opening in the washer to prevent rotation of the post, a washer of in sulating material disposed about said post and bearing against the outer surface of the top of the casing, a wear-resisting Washer ?tting about said post and against the outer insulating washer, a nut screwed upon said post and bearing against of conductive material ?tting about said post be broken or worn out may be very easily rendered operative as a starter actuated by pressure upon 10 tween its head and a confronting portion of said liner, said washer having snug ?t within the eas a push ‘button switch. a clear understanding of the invention after con sidering the description in connection with the drawing. Therefore, a more lengthy description is regarded as unnecessary. Minor changes in the shape, size and arrange ment of details coming within the ?eld of in vention claimed may be resorted to in actual practice, if desired. What is claimed is: A terminal adapter for a self-starter compris the wear-resisting Washer and ?rmly holding the post in place when tightened, and a second nut screwed upon said post and constituting a lock nut for the ?rst nut and serving as means for securing a conductor wire to the post. ing a casing having tongues extending therefrom and adapted to be secured to a starter and dis 25 HENRY M.
