Description

. To` all whom it may concern! y jBe it knownthat I, DAVID E. SrEAnNs, of Berea, `in the county of Cuyahoga andin the e State 0f Ohio, have invented certain new and `usefullmprovementsin Sewing-Machines; and dohereby declare thatthe following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and l to the letters Vof reference marked thereon .i a e making a partv of this speciication. y

The nature of my invention consists inthe construhtion andarrangement of amechanism for running sewing-machines, as will be hereinafter more fully set forth. In order to enable `others skilled in the art l ,to whichmy invention appertains to make-and e use the same,-1 will `nowp'roceed to describe its construction and operation, referring to the annexed drawing, in ywhich` l Figure 1 is a sideview of a sewing-machine with `my running `mechanism attached, and a Fig. 2 is an enlarged lplan view of the means for winding up said mechanism. n Arepresents the machine-table; B,the standard; and C, the `needle-shaft of a sewing-mae chine. Below the tableA,-and connected therewith by bolts or other suitable means, is a plate orbed, D, andbetween said plate and table `are arranged two vertical shafts, E and G. H represents a coil spring aroundthe shaft E, the inner end of which spring is fastened to the shaft, and the outer end to a large cogwheel, I, placed loosely upon the shaft. The ,shaft E ismade to revolve so as to wind up the spring, bymeans of `a ratchet-wheel, J, and ratchet-lever K, upon the lower end `of the shaft. "The cog-wheel I gears with a pinion, L, upon the shaft Gr, and on said shaft is a i bevel-wheel, Mfwhichengages with a similar Wheel, `M', on ahorizontal shaft, N. i This latter shaft is, by means of `suitable gear-wheels O O,`connectedfwith the end of the needleshaft @,fas shownin Figl. The inner end of `the. springH, being fastened'stationary to the shaftE, causes the strain to come from the 1 ing it up; and from the outerjto the inner end i while unwindin g the shaft E being then held nUivrrnn S'rn'rns inner totheouter end of the spring in wind- Pnriiniv'r @raton `nhvin n. s'rEAnns, onfBEnnA, Assieivon To HIMsELF, sAMUEL M.

IMPROVEMENT 1N MoTlvE PowERs FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 115,379, dated May 30, 1871.

handy, so as to enable the operator at any time to operate it by winding it on the screw by turning the same; or the string or wire a may be held with the toe of the shoe at the bottom, in which case the Vends of the brake vshould be fastened to some kind of foundation; or one side of said brake, when drawn sufficiently tight upon said needle-shaft either to stop or regulate its motion to a required degree of speed, can then be hastily wound around some stationary peg, and there held constantly to such motion as required, or to the stopping-of all motion.

1 In winding up the mainspriug upon the shaft E it will be noticed|that the shaft turns in the same direction that the wheel runs, by which means the motion of the needle-shaft does not stop while winding.

It will also readily be seen that, from this mode of propelling the sewing-machine, it

does away with the massive and heavy balreadiness of transporting it about the house,v

but also by reason of the readiness and cheapness of packing it for transportation about the country.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

` 1..Il1e combination of the shaft E, spring,
