V OCONNOR, a citizen'of the United'f'States,

and a resident of thecity of New York,

borough of Brooklyn, in the county of 'Kings'- and State of vNew York, have invented -anew andlm roved-'TypeeWriter Ribbon- Spool, 'o' w ich 'the'following" is a full,

' provided with a cast hu 'to which .theanges clear, and exact description.

The object of the; invention 'isV lio-provide a new and improved ty ewriter 4ribb'on'spool are riveted, thus pennittingquick, convenient and accurate assemblm vof the parte without the aid of. highly s therebyreduoing the cost of manufacturing hg).

to a minimum.

The invention consists of novel featuresand parts and combinations of the same, as will be more fully described hereinafter and. then pointed out inthe claim.

A practical embodiment of the invention is represented in theaceompanying drawings forming" a part of'this specification, in which similar characters of reference indicate corresponding parts in allthe views.

The terminals of the ends A are riveted against the outer faces of 'the fliinges'B, B, so that the rivet heads securely hold 'the flanges B, B, in position on the ends A of theliub A and 'against the shoulders A.
