IMPRO'BME'T IN MOTIvE-POWER FOR SEWING-MUH'INES.

WM l The Schedule referred to in these Letters Patent and making part of the sama To all whom t-may concern Be it known that I,' Enwnnn J. LEYBRN, of Lex ington, in` the county of Rockbridge and State of Virginia, have inveuteda new and improved Mechanical Movement Applicable lto Sewing lldaehinexy; and I do hereby declare that the following is a full, clear,

and exact description thereof, reference being had to the accompanying drawing making part of this speciiication, in which- Figure 1 is au elevation of one side of myinvention, v

applied to the table of a sewing-machine.

Figure 2 is a similar view 0f `the same parts, but

representing them iu dil'erentV positions.

Figure 3 is a top view cf-fig. -L Figure 4 shows the left-handelde of the seat and its supporting-frame.

y Y Similar letters of reference indicate-corresponding parts in the several iigures. e

This invention relates to certain novel improvements on mechanism adapted forlessening the manual labor required to operate sewing machinery and other light `machinery.

The nature of my invention consists- First, in the application of a driving belt-wheelto a shaft, which forms the axis of an oscillatingseat, the

l latter having the table of the sewing-machine` applied to and supported by an arm extending from and movi ingwith it,`in combination with a treadle, which is` 0011116015641. by xCds and Ieyers, to said wheel and seatarm, as will be hereinafter explained.

Second, in so.contriviug thc connection between the treadle, the movablel seat-arm, and the driving belt-l Wllel, um, by il Simple adjustment of the upper end of one ofthe connecting-rods, the table and seat can `be rigidly fixed and motlon communicated to the driv 4ing belt-wheel by means of the treadle motion, and

Without moving. the body. i

Third, in an adjustable`f0otrest en the trcadle, ju combination with an oscillating seat, having a `table applied to an arm extendingfrom it, whereby the treadlc i can he adapted for 'large or small persons sitting in the anat, as will he hereinafter explained.

` To enable others skilledin the afin-to understand my invention, I will explain its construction and operation. I y

In the accompanying drawingi A represents a stool or` stand, by which the mechanism is substantially supported.

a c, extensions of the logs of this stand, to which a treadlc, T, is applied, bynpvots s, and to one of which afstud, p 1:, is fastened, which aliords a. fulerum for a `connecling-rod, J. 1 A' B is a seat-dame, having applied to it, by means of springs, or otherwise, aseat, s, upon which the operatm' is supported while working the machine.

Theback of the seat maybe made elastic or rigid, adjustable or not, as circumstances require. This seat ifi/jointed, by the standards of its frame, to a horizontal shaft or studs cast on inner side of stool nprights 0r bar i, on one end of which turns ailriving belt-wheel,

D, which also serves as a balancenvheel.

'This seat-frame B is constructed withan arm, B', extending upward and forward, in such manner as to afford support to the table Con which the sewing4 machine is secured. The table (l, thus supported, is arranged in a convenient position to a person sitting in the seat lS, andvwill vibrate about the a-x'is of the shaft or bar fi, with the seat and the person thereon.

Around the small wheel `D' of the sewing-machine, a belt is passed, which,'bei ngcarried amuud1the driving-wheel' D, will communicate rotary motion to the shaft of wheel D when the wheel D is rotated. A Eceeutrically to the outer side of wheel I) a wristf pin is applied, to which one end of a pitman, P, is attached. 'lhe other end ot' this pitman is'pivoted to one end of a'vertically-vibratiug lever, L.

Thislever has its fnlcrum at b and at c c2. Two rods are connected to it, one of which, J, is pivoted at c to said lever, and at p to the stand A. The other rod,

lK, is pivoted at czto leve; L, and to a wrist-pin, an,

at the outer forward corner of the treadle '.l.

Between the studs or pins c ci, which maybe adjustable, is a stud or pin, c, which may be'hxed or adjustable, and which is adapted for receiving the upper end of either one of the rods J K, when it is de-V sired to shorten or lengthen the strokes ofthe lever L or treadle .l. i

The stud b, which is' fixed to the arm B' of seati'ame B, is made long enough to receive the upper end of the rod J, and, when this rod is thus adjusted, it will be seen that it -will serve as a brace for rigidly holding the seat-trame when it is desired to operate themachiue by the treadle T alone. Thejtreadle T is pivoted, at s, to the extensions a of the stand A, as above stated, so as to receive from the feet of an operator upon the scat S an oscillating motion, which motion, alone or in conjunction with a rocking motion given to the seat-flame and table, will he communicated to lever L through one or both of the rods J" K, and this leverwillrglve a rotary motion to the wheel D, which will rotate the wheel D', as`

above described.

For very light-running machines, lthe treadlc may be stationary, it' desired, in which case the rod J will he omittcd,.aud the motion obtained hy the action of the body upou'the vibrating seat.

It will he seen, by reference to figs. 1 und 2, that a I foot-stand, t, is pplied to the treadle'T, and that this stand can he adjusted higher er lower, iu a plane paralel to the trcadlo, by means of the set-screws y y,

which connect the stand to post v n. This feature is rod K, lever L, pitman P, and wheel D, substantially useful in my machine, as it allows the machine to be as described.
