Our Patented Variable Roving Traverse Motion - ==^,,^ is supplied. It is adjustable as to length of traverse, and has a vari-able motion which prevents un-equal wear of leather top-rolls. The Spindles with whichour frames are usually equippedare of the well-known WhitinGravity type. They are made inthree standard sizes ; viz,Standard Gravity, MediumGravity, and Large Gravi-ty. They are all of thesame general construc-tion, but vary as to theirweights and diameters ofRoving whirls. Traverse. Page 12 For spinning warp yarns we recommend the Large GravitySpindle for coarse yarns, from 4s to 12s; the Medium GravitySpindle for all counts from 12s to 24s; and the Standard GravitySpindle for all counts finer than 24s. For spinning filling and hosiery yarns we recommend theMedium Spindle on coarse counts to 20s and the StandardSpindle on all finer counts. We also recommend the use of large whirls on spindles, thisassures regular speed, uniform twist, less breakage of bands,and a reduction in repairs in spindles and cylinders. The following spindles are what might be called Regular,as regards sizes of whirls : Standard No. 1 diameter of whirl | inch 2 \i Medium 1 i ,i 2 1 Large 11 To suit special conditions the Standard Spindle may befitted with f, {f, I, }i or 1 diameter whirls ; the Mediumwith J, |;V, V, tI> 1> It/, oi diameter wh
