"Vintage Machinery" entry for Diehl Manufacturing Co.
"In the installation of driving mechanism involving a motor and a friction transmission device for operating small machines, such as sewing machines, lathes, &c. involving the employment of a connecting belt, it has been customary heretofore to ship the motor and transmission devices separately and to assemble them into operative relation by securing them independently to the table or frame of the machine to be driven. In certain devices of this character, such method of installation has involved the setting up of the component members in a defective alinement, and it is the object of the present invention to insure the perfect assemblage of the parts by permanently securing them together before installation in connection with the machine to be driven."
