SELF-BINDER.

SPECIFICATION forming part of Letters Patent No. 266,937, dated October 31, 1882.

Application filed .T une 27, 1882.

To all whom 'it'may concern:

Be it known that we, WILLIAM N. \'l\I3IfIE.-` LEY and WILLIAM BAYLEY, of Springfield, in the county of Clarke, State of Ohio, have invented a new and useful Improvement in Self- Binders, of which the following is a full, clear, and exact description.

Figure l is a perspective view cfa seltbinder with our improved butt-evener and adjuster attached thereto., Fig. 2 is a sectional elevation of the same. Figs. 3 and 4 are views ot' modifications in construction, and Fig. 5 is a plan view of a detached belt-guide.

This invention relates to canvas endless aprons used for the purpose of straightening up the butts of straw and delivering the grain nearly central to 'the binding mechanism, whether the grain belong or short; and it con- -sists in an endless canvas belt ruiming upon rollers that are provided with journals that are both yielding and resisting, in order that they may compensate for the expansion or contraction of the material from which the beltis constructed, said belt being pivoted upon its driving-roller, so as to permit of au adjustment at its free end to or from the binding-arm to suit long or short straw.

rl`o ena-ble others skilled in the art to which our invention belongs to make and use our improvements, we will proceed to describe their construction and operation.

a is the binding-table, and b the elevatorframe, which may be of any suitable construction, as may also the binding machinery c.

l is the butt-evener and grain-adj uster, jour naled to the elevator-framing by a foot-journal, c, andan overhanging journal, f, by which construction and arrangementit will be free to oscillate, so that its'free end may be moved nearer to or farther from the position g, where the binding'cord encircles the sheaves.

The driving-roller 71l is actuated by bevelgear t', that receives its motion from the upper roller ofthe lower elevator-belt. The driving and driven rollers l2, l, respectively, are supported by a rectangular frame, m m m fm", and side guides, n n', upon the latter of which the edges of the s latted canvas travel and receive their side support. The rectangular frame m m m m is bolted together by screwbolts 19 p 17'19"', and are thus made for convenience when placing the rollers h l into their (No model.)

working positions. VThe guides un are provided with elongated apertures q q', through which thejournals ofthe driving-roller 7L work, and cylindrical perforations r r, through which the journals of the driven rollers l work. These guides n n are also provided with aperturess s', through which the uprights m" freely pass, in order that said guides may have an unobstructed motion in the directionoftheir length. The apertures s s are tted with metallic pieces t t, that are fastened at one end to the guides n 'n' near the roller Z, and then work freely through perforations fu, made in the uprights m" at the other end. Surrounding the stems of the metallic pieces t t are coil-springs c o', that force said metallic pieces away from the upright m, and, keeping the canvas taut, enable it to force back heavy and tangled grain.

Fig. 3 is a modification illustrative of a change of construction, whereby one spring. fw, takes the place of the two springs n o' and a T-shaped metallic piece, x, takes the place of themetallic pieces t t. Fig. 4 is a modification wherein both bars m" m are placed between the end rollers.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, isy l. A continuons and revolving butt evener and grain-adjuster swinging upon the journals of its driving-roller through the agency ot' a rectangular frame, m m m m", so as to ad- Init of an adjustment of its free end to suit the varying lengths of straw and bring the grain centrally on the table for binding, provided with guides n n', having perforations q q', apertures s s', and springs o c for forcing the roller l away from the upright m", for the purpose specilied.

2. A continuous and revlving butt-evencr and grain-adjuster, d, swinging upon the journals of its driving-roller through the agency or' av frame, substantially such as hereinhefore specified, provided with guides n n', having perforations 'q q', apertures s s', metallic pieces t t', and springs o o', for the purposes specified .WILLIAM N. WHITELEY.
