Beit known that I, GEORGE W. PENNIsToN of North Vernon, in the county of l Jennings and State of Indiana, have invented certain new and useful Improvements in Presses for Cotton, Hay, Ste.; and I do hereby declareing and releasing the doors of the press-box,

and in fastening the pulley-block tothe rock` shaft, to relieve it of some of the pressure in working the press.

In the accompanying drawings, A is the base of the press-box, connected to the top bars, B B, by the posts G C C G', to make a strong frame, the top bars, B, being connected bythe cross-bars D D. The planking for the sides of the press'is fastened to the posts C C, and the top C of the press-box is arranged to vibrate on the rod C, so that it can be opened to fill the press and then closed and secured by theV rod C2. The door E is hinged at E and secured by a catch at E2. There are two doors like F one on each side-hinged in the bars I)"D2, and when closed are held by the lockingfbar F^ and clevis F2, hinged to the endof the bar Fl', and shown open in dotted lines in Fig. 2.` When the doors F are closed and the clevis placed in the position shown at F2, parallel with and on the bar F, to hold the doors to, the clevis is held parallel with the bar by the key F2, (shown in Fig. 3,) with a forked end, which is placed upon the clevis and bar, and

4'hinged to the traverse-rod F, which vibrates the key and releases the clevis, so that the elasticity of the article pressed throws theV doors open.

The plunger G is shown in elevation in Fig.

y4c. It is made long enough to allow the` togglethe ways G3 on the sides of the; press-box..

(Shown by dotted lines infFigsQl and 2.):1 In.)` f order to preventgtheplungerfrom rocking and?. making the bales of unequal thickness, I put in` 1 e the braces G* G,to stiffen it and hold the plunl f 1 e j ger parallel to the endof `the press, and the@` roller G5, under the point of connection .withfyh the togglelevers,relieves theplunger of lnznichi"l of the friction which wouldotherwise impede the progress of the plunger. The toggleflevers l l G' G are connected to the three toggle-barsH` L H H `by the .pin H, one ofthe bars supporting the pin between the levers and the other twoj i bars outside th elevers renderingit very strong.. g

'and making it a most powerful press. They e e lower ends of thetoggle-bars Hj are fastenedto the rock-shaft H2, which shaft turns inll the V blocks H2, between the posts C,and carries tl1`e` 1 1 arm H, and screwI, whichstrikesythe rod Ff` l and moves it so astorelease the keylliei` when l l the bale being pressed is small enough, and let f l e the doors of the pressopem 1Thepulley-blockyg I', Fig. 5, is fastened `tothe rock+shaft H2, and l ,y

is provided with projections `I2,to hold the`pul-`l ley from swinging toward therock-shaft, soas; ,1b. j to bind the rope whenthepressis drawn opens f e The rope I2 is fastenedto oneof` `the toggle-le:l l f vers G', and passes around-:the pulley in" the"` block I and up overfthe pulleybetweenlthes e toggle-levers G', anddownunder the pulley in l the block J, fastened to thebase `A, and" fromjl y .y that to the windlass-barrelJ, uponwhich itis j 3Q wound by a horse attached tothe lever .12,"fast-g r ened tothe shaft J2e-of the windlass shown in l Fig. 8. The windlassbarrel Kl is right under.

the windlassibarreld, and is connected to the plunger' G bythe rope 3K', which. draws3 back the plunger after` the bale pressedllwhasl l been bound. The ,shaft J2 is supported by the; 3 frame K2,`and is arranged toturn freely in bothf r y e l windlass-barrels, and is provided with aclutch-` l;

block, K3, which iscarried from one windlass-" barrel to the other by raising and lowering` y the barrels by the lever L, so as, to `lock then z `l barrels to the shaft alternately towork the ltog"` gles, and press a bale or` retractthe press, each; u windlass-barrel having a cavity in it," as shown e in Fig. 7, for the block K2. The lever\L,which1 1 l;

raises and lowers the windlassfbarrels, `has itsf` fulcrum at L', andis crossedbygthe.lever` L2V,;` which is locked down by the `latch L3,Fig. 1, so `1 as to hold the barrel K up tothe block Kat i. `Byl l l. e `1 swinging the latch one side, both Windlasses Willvdeseend, so as to lock the upper one to the shaft. This arrangement of Windlasses allows the horse that carries the lever J2 to travel all the time in one direction, and saves the time and labor of turning twice for eachbale pressed. To fill this press the doors E and C are opened and the press-box lled with the cotton or other material to be pressed, and the doors closed and fastened, as heretoforedescribed. The Windlass is then Worked to draw down the toggle-levers until the screw I operates the bar FL and releases the doors F F, `when the bale is ready to receive Vits hoops, after Which it may be removed.

My'improvements make a press cheaper in yproportion to its capacity, which may be:

Worked with a given pressure, With less power,

and in far less time than any other press made prior to the date of my invention.

' I believe I have described my improvements in presses so as to enable any person skilled in the art to make and use them. I Will 110W state what Idesire to secure by Letters Patent, viz:

ll. The clevis F2, constructed substantially as described, in combination with the bar F and key F3, for locking and releasing the doors of the press-box, as specified.

2. Fastening the block'I to the rock-shaft H2, so as torelieve it of some of the pressure in Working` the press, as set forth.
