That I regard as new, and desire to secure by Letters Patent, isvr 1. A needle-threader, comprising a shank carrying an upper guide-prong and a lower guide-prong which lie in diilerent planes to ada t thern to einbraee a needle, a threadhoo projecting into the eroteh between said guide-prongs, and a rearwardly extending guard crossing the space between the horizontal planes of said guide prongs, whereby the thread may be passed beneath the upper guide-prong and above the lower guide-prong, then moved, while ridingr on said guard, to pass said thread-hook, and finally retracted and guided by said guard into operative engagement with said thread-hook.

2. A needle-threader, comprising a nieinber equipped with upper and lower guideprongs, one of said prongs carrying a rearwardly and upwardly pointed guard-arm, Said guide-prongs lying on opposite sides of a needle-reeelving space, and a thread-hook extending into said space and lying between the upper guide-prong and said guard-arm, for the purpose set forth.

3. A needle-threader, comprising a sheet- Inetal inelnber having the metal split longitudinally at one end and the fureations struck in opposite directions to alord guidebetween said guard-arm and said upper fure ation 5. A threader, comprising a sheet-metal member formed with. oppositely struek upper and lower fureations and with a rearwardlypointed guard-arm, and a separately formed thread-hook secured` to the shank of said sheet-metal member and having its operative end lying between said guard-arm and the opposed fureation, for the purpose set forth.

6. A threader, Comprising a shank and upper and lower fureations carried thereby and separated by a needle-receiving space, and a thread-hook having its operative end extending into the eroteh between said fureations, the extren'lities of the l'ureations projeeting past the o Jerative end of said thread-hook, whereby the thread may be drawn between the adj aeent edges of said fureations and earried past they prong of the thread-hook and then retraeted and carried into operative engagement with the tlnead-l'iook.

7. A threader, comprising a shank and two lureations` carried thereby located on opposite sides of a vertieal plane to provide bel tween them a needle-reeeiving spaee. the 1 lower surface of one fnreation being near the level of the upper surt'aee of the other fureation, one of said fureations being longer than the other, and a thread-hook having its operative end extending into the eroteh between said l'ureations, whereby the thread may be drawn between the adjaeent edges ol' said l'urcations and earried past the prong ot the thread-hook and then retraeted and earried into operative engagement witlle the thread-hook.
