I have a weird standing mixer

So I just came into possession of a used standing mixer (my dad bought it from a garage sale ages ago and just gave it to me) and it has these bizarre attachments that basically look like curly fries. He said to use them for bread ( lieu of a bread hook...?) and so I did and they just barely do the job.
Has anyone else ever seen these attachments? Are they supposed to be used for bread or something else?
