Tintinnabulum (tinnio) is an instrument for making a ringing noise, a bell: lanios inde accersam duo cum tintinnabulis, Pseud. 332; tintinnabula quae vento agitata longe sonitus referant, Plin. 36, 13, 19.
Pabulum (pasco) is that with which anything is fed, usually with reference to the feed of cattle: bubus pabulum parare oportet, Cato, R. R. 54, 1.
Venabulum (venor) is a hunting spear, an instrument for hunting: tantam bestiam percussisset venabulo, Verr. 5, 7.
Exorabulum, which occurs only twice, is perhaps rather the begging (exoro) itself, which is, in turn, a means of obtaining something: quod modis pereat, quotque exoretur exorabulis, Truc. 27; exorabula incidantium, decipula adversantium artificia dicentium perdidicit, App. Flor. n. 18. The first example is interesting as the noun is used with a form of the same verb as its verb stem.
Vocabulum (voco) is the instrument for calling or naming, a name: si res suum nomen et proprium vocabulum non habet, De Or. III, 159; Aristotelis orationis duas partes esse dixit, vocabula et verba, ut homo et equus, ut legit et currit, Varr. L. L. 8.
Two interesting analogical formations with the suffix -bulum are nucifrangibula and dentifrangibula in Plautus: ne nucifrangibula excussit ex malis meis, Bacc. 598; ita dentifrangibula haec meis manibus gestiunt, Bacc. 596.
