TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY MILLER, ot' Ronald, in the county of Ionia, and State of Michigan, have invented certain new and useful Improvements in Spinning-Wheels; and I do hereby declare the following to be a full, clear, and czact description of the same, reference being had to the accompanying drawings, making a part of this specification, and which represent aside view of the spinning-wheel complete, and its parts in two different positions, by black and rod lines, said drawing being marked Figure 1. i

My inventio'fconsists in the manner in which I have combined and arranged the several operating parts of the spinning-wheel with a foot-treadle, so that the operator can readily, with the foot, throw the spindle or bobbin from or draw it towards his or her position, Vas will be explained. 4

To enable others skilled in the art to make and usc my invention, I will proceed to describe the same with `reference to the drawings.

A represents a frame upon which the main driving-wheel B is hung, which driving-wheel is operated'by a.

crank, C, or any other equally well-known appliance. To the front of the main frame there is securcdthe upper-end of a foot or brace, I), the lower end of which, projecting and inclining forward some 'distance from the main frame, rests upon the iloor. Near the lower end of this foot or brace D, and in a slot made therein, so tha-t it can he adjusted, is a cross-head, E, having standards or bearing-blocks F attached; andv the cross head, whenadjusted, may be held firmly by a key, a, driven through its tenon b, which passes through the slot in the brace or foot, or by any other adjustive mechanism. Near the tops of the standards or bearers is pivoted the spindle or bohbin-arm G, as at c; and on the top ot' this spindle-arm, ina cross-head, d, are arranged bearers e in iwhich the spindlef is caused to run. A driving-band lor cord, g, extends over and around the main d rivcwheel B, and may pass under and partially around a pulley, z', arranged at or in line with the joint c where the spindlearm G is pivoted, and thence may pass around the pulley m on the spindle f, for the purpose ot' driving said spindle; or, which would he probably a better method of driving, the main belt may only go around the mainwheel and the pulley fi; and from the pulley i to the pulley m on the spindle, a second belt or driving- In this latter case, a pulley with a series of grooves of diierent diameters may be used, so that m'ore or less speed may be given to the spindle, as may be required. To the supports H H (for convenience) is pivotcd, by its journals 7L Ah, a foot-treadle, j, which projects about equal distances on each side of said journals or supports, and so that it may rock both ways,- or front and rear. To the forward end of this foot-treadlej, as at n, there is pivoted the lower end of a pitman or connecting-rod, Land the upper end of this pitman is connectedat o, to the short arm ofa bell-crank lever, J, which is pivoted to the supports H (and its mate or fellow behind it, and not seen in the drawing) at pl The long arm of the `right-angled (or nearly so) lever J is furnished with a series of adjusting-holes, T, into one of. which a pin, s,

passes, which attaches to said lever a second pi'troan or connecting-rod, K, the forward end of which is hinged, as at u, to the spindle-arm G.

When the treadl j is pressed down at its front end, or the end where the toe part of the foot rests, the several parts connected with and operated by it will be in the positions shown by the black lines; and when the after or heel portion of the trcadle is pressed down, then the several parts connected with and operated by the treadle will be in tliepositions shown by the red lines. The object in moving the spindle or bobbin from and towards the operator is, first, to draw out the roving or roll of wool into the form of thread or yarn, and when it is sufciently twisted by the running of the spindle, then the spindle is` brought towards the operator to allow the yarn to wind up on the spindle or bobbin, and so on. The belts, whether single or double ones, having the centre of their pulley z' in the same line with the pivot c of the spindle-arm, do not become slack by the moving v of said arm, the central points of the pulleys and main wheel being always equidistant from each other in the line of the belt or driving-cord.

Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is- 4 l The arrangement of the adjustable and hinged rods and levers, constructed as herein described, for' connecting the rocking-treadle with the hinged spindle-arm, so that the operator, by the foot, may move the spindlearm out or in at pleasure, as setforth and represented.

HENRY MILLER.
