IMPROVEMENT lN HAY AND COTTON-PRESSES.

The Schedule referred to in these Letters Patent and making vparl: o the same.

To all whom. it may concern.-

Fifure 2 is a`transverse section of the nutgund beam'4 D upon which 1t4 works. Figure 3 i-s a perspective view of my hinged clamp.

'This invention relates to an improvement on an iin-- proved cotton land hay-press patented September 28, 1869, by Joseph K. Davis.

The first part of my improvement consist-s in providing two of the uprights at the saule end of the frame of .a hay or cotton-press with scarf or beveled joints and catches, which also act as supports, the object of the. invention being to permit that portion of the frame above the joints to be drawn from a-perpendiculur `to an inclinedposition :unl replaced at pleasure.

A A are scarf'or beveled joints, working on hinges in the uprights B B. A

O O are catches, which act as supports when the frame above the joints A A is placed in an inclined position. y l A The catches G O have notches, cZ d, which receive the pins e e ou` hotlr sides ofthe 'uprights B B, and

hold the uprights when' perpendicular.V

'ff are notches, which receive ,the'rouuds ofthe catches G C. \Vhen'the top of the frame is drawn outward the catches then become supports.

Cleats G G are fastened tothevuljirights directly beneath the gir-der H, andforma-resti'ng-place for'the end ot the lid 1 when the doors J are open and the top of the frame inclined. The hinges k Icare thus prevented from breaking. .i

L L are nuts, whose upper portions are.'rectangnlar while their loweljpol'tions are curvilinear` Their Vupper portions are provided with -mortises,

'm m, forthe receptionof levers, which vary in length. The lower portions are provided with grooves, n n,

for 4the reception of a cord, byiwhich they may be both screwed up or down rapidly at the same time.

The nuts L L are provided with grooves o o, and the seats 1) 1) have corresponding grooves.

v Friction-balls, q g, are introduced into the spaces formed by the meeting of the grooves when the nuts L Ljare placed upon the seats pp The object of introducing the balls q q is to reduce fthe friction as muchas possible.

The clamp R has the lever 'S connected to it bythe hinge T, when in its place on the'press.

- The lever S is parallel with the upright B, and is held so by a pin or nail in the upright, behind which .it is placed. v

U U and V V are cross-pieces and braces used to strengthen the frame of' the press. f

The lid I can be raised and held in an elevated position by the hooks :c x. Y

The operation o t' my improvements .can be readily understood. Raise the nuts L L on thescrew until the girder H will clear the lid I.v .Raise the catches -G C from the pins ee, and drawthe upper portion of the frame into au inclined position', permitting the `rounds ofthe catches to enter the notches j f. The

lid I will then Vrest ou the bale, if one is in the press ii' empty, it will rest on thc cleats G G. Release theA levers S from their places behind the nails or p'ins, and

`the expansion of the bale of hay or cotton will at once force the clamps R It off andthe doors J .J open.

lh'e lid I can now be raised and held up by the hooks at a: V. A

By placing a cord in .the grooves n n and drawing upon it with the hands, both nut-s can he worked down rapidly at thc saine time..

. AHaving thus described my invention,

wWhat I claim as new, and desireto secure by Letters The uprights B B, provided with scarf or beveled joints A1A, catches C C, and notches ff, as and for the purposes hereinbefore specified.

To theabove specification of my invention I have signed my hand this 1st day of August, 1870,
