This weight H (see Figs. and simplify the construction of bobbin-hold- 1 to 3) is mounted eccentrically on the upers in use in spoofing-machines, whereby the wardly-extended arm G, which is shown as said holders are better adapted to hold bobcomposed of two parts, one being a screw bins from which yarn is being unwound, so screwed into a boss on the arm, the boss servf5 r5 that this yarn may be reeled off without any ing as a shoulder, between which and the injurious jumping of the bobbins. head of the screw the eccentricallybored The improved holder to be herein described weight may be clamped in an adjustable poconsists, essentially, of a concaved rest or supsit-ion.
