ABSTRACT:
An embroidering tool comprising first (18), second (23), third (25), and fourth (30) longitudinal and generally cylindrical elements coaxially arranged and each with a longitudinal bore-like cavity (22, 17, 13, and 36) extending therethrough with the first (18) and second (23) elements threadably engagable with each other with the second element (23) comprising a hypodermic type needle (10) and a threaded needle hub (16) with the hypodermic type needle (10) having its proximate end secured in the bore (17) of the needle hub and with the threaded needle hub (16) threadably engagable with a threaded first end (15) of the first element (18), and the third element (25) coaxially surrounding a portion of the first element (18) and being threaded on its inner (31) and outer (33) surfaces beginning at a tapered, compressible first end (48) thereof to allow compression of the third element (25) against the first element (18) to lock the third element (25) against the first element (18) to prevent relative movement between the first (18) and third (25) elements. The fourth coaxial element (30) surrounds portions of the first element (18), the third element (25), the needle (10) and the needle hub (16) and is threadably engagable with the third element (25) from the first end of the third element (25) and further has its bore-like cavity (36) configured to compress the third element (25) against the first element (18) to prevent movement therebetween when the third element (25) is threadably engaged with the first element (18) a predetermined distance, and with the longitudinal position of the third element (25) with respect to the first element (18) determining the amount of extension of the needle (10) out of the fourth element (30) when the fourth element (30) is threadably engaged with the third element (25) by the predetermined distance.
