Abstract
An embroidering tool comprising a barrel serving as an outer shell with a slot having notches for receiving a pin located on the outer surface of a shaft inserted into the bore. An interchangeable tip having a cannular needle pressed therein is inserted into an axial bore within the shaft and locked therein. The shaft is then assembled with a spring and inserted into the bore of the barrel with the pin moved along the slot until it is engaged within the proper slot setting. The invention provides an embroidery tool in which the mechanism for adjusting the exposed length of the needle is extremely durable, simple, easy to manipulate, and rapid and consistently precise.
Claims4
An embroidery tool comprising:
- elongated body means having;
- a forward end, a midpoint and a rearward end,
- a smooth wall bore extending axially therethrough,
- a longitudinally oriented first slot opening into said bore, said first slot starting aft of said midpoint of said body and running towards said rearward end and ending in a retracted notch,
- a plurality of aligned parallel notches on each side of said slot,
- a second slot having an opening starting at said first slot rearward of said notches, and opening into said bore starting forward of said retracted notch and perpendicular to said first slot, and having a back end,
- a third slot opening into said bore starting at said back end of said second slot and longitudinally oriented parallel to said first slot and ending at said rearward end,
- a shaft, having a forward end a midpoint, a rearward end, and an outer surface slideably engaged within said bore in said elongated body, and having;
- a bore extending axially therethrough,
- guide means on said outer surface of said shaft forward of said midpoint of said shaft for guiding said shaft in said slots and notches, and
- cam means formed in said bore at said forward end,
- an interchangeable assembly having;
- a needle, and
- a tip having a pair of tabs for engaging said cam means when mated within said shaft bore, and
- compression means assembled over said needle for yieldingly urging said needle assembly and shaft in a rearwardly direction for maintaining said guide means in each selected position.
