IMPROVEMENT IN OIL, Tom-ccc, AND-OTHER ressens.

To ALLwHoM 1T MAY GQNCERN;`

Beit known that L'ENccH-THOMAS', of Craigsville, county of Augusta, State of Virginia, have invented a new and useful Improvement in Cotton'and HayPresses; and. I do hereby declare that the followingv is a, full and exact descriptionthereof, reference being had to thelaccompanying drawings, and to the "letters of reference marked thereon. e

The nature of'my invention consists mainly in double-acting togglellevers with thefollowcr f a press for oil, tobacco, cotton, hay, 8vo., in combination withdouhle-acting sectors and eccentric-wheels, whereby thepower of the levers is brought to bear alternately upon 'the follower.' i

In the accompanying drawings, which make apart of this speciication- ,l

. Figure 1 is anjisometrical view ot' the improved press. i

Figure 2 isa vertical longitudinalseetion ofthe same.

Figure 3 is a top viewof the sliding framel, connecting-rods ff, andi-ods d d.-

-Figure 4 is an edge view of the same. V

Figure 5 is an isometrical view of the eccentric-shaft T and lover U.

Figure-Gis a like view of the follower-franie-D.

Like letters-in all the vfigures indicatethe same parts. i

A represents. thestanding frame off the press, which may be made either of wood or iron. B is the head of the press, between which and the follower C thematerial is`pressed. D is the follower-frame, which slides "in grooves, a a, in the u'prights' b. Therearc togglejcnt levers,E E' and F F', jointed atthelower ends ci' E and F tothe crossfpieces Gr G. The upper'ends o irE and F' are pand-shaped, and in the pressing-operation of the leverscatch in the ratchets c c, \vl 1ich` are formed on the edges of the follower-'frame D. t

The rods cl cZ are connected at their ends, by means of the joint-pins e e, with the toggle-levers, and the connecting-rodsff are connected atzonclend to the rods d d by means of the pins e' e', and at their other ends -are permanently connected to the rocking-shaft H, whichlhas' its bearingin the horizontal slidingframe I, so

that the reciprocating 'motion of the sai'dframc gives' an alternate 'actionto the toggles and produces a double' action of thc'samei., i l i A shaft, running clear through the `connecting-rods d ci and the'connecting-rods ff, should take the placeof the pins. e el there beingl openings in the'followenframe D of suiiicie'nt' capacity to` allowof a free lateral movement back and forth of the saidV shaft, inthe operation-oi' the sliding frarngc I.

` T hc'said shaft H is provided withsectOrS, J; andthe rocking-shaft H', at the other end of the frame, has like hsectorsfd'J'.

K'is a shaft, which has its bearing' in thestanding frame A. On' this shaft there are eccentric-wheels, L L, which, by pressing upon the sectors JJ aiid J' J' alternately, give a reciprocating motion to the framel, and operate the togglcs for elevating thefol-lower C, vthe upper ends-oi' the levers E' and F', being pressed into the ratchets c c of the follower-frame D. The shaftlK is'revolved by means of itsbonnection with the drivingshaft'M, there being a 'cog-wheel, viN, on one end of the shaft K', and a worm-piniodn, O, on the driving-shaft M. i l is-a {ly-wheel, on the outer'en'd of the shaft, the momentum of which increases the leverage of4 the press. It may also serve as a band-wheelto connect with tliem'otive-power. u some cases hand-power maybe used,

lthe said `wheel being provided with al liandle, 7z.4 There ris ahy-wheel, B., on the opposite end of thp shaft fK, which also increases thclevei'agc oi' its momentum', and the increased diameter of its rim over that of`tlre eccentric-wheels L L. lhese wheelslmay be usedlfconjointlm'as represented in the drawings, ori one lmay be used without the other, and may be .shifted from one shaft toA the other, as circumstances may require. Frictionm'heels `maybe used, if desired, 'in place of thesectorsJ J and lfd'.

S is a friction-wheel, in' one of the uprights, 6;" 2It vturns-on thel eccentric-shaft T, which is provided with a lever, U, for changing its position. y

' Thel crank and shaft are shown in detail'iniig. 5.

The object of this wheel and-crank is to sustain the follower-frame D, upon which thewheel bears when the toggles are being release l. Whea the follower is to be lowered, the crank is turned outward, to release the wheel from the frame, to allow the latter todrop gradually.

There is a lever, V, connected with the piecesY E andFot the toggles by ineens ofthe cords e' z', arranged as seen in fig.l 1,'f`or disconnecting the levers-from the follower-frame D. When the .follow'erlis to be lowered,

- ut other times, the springs W W, whose heels are secured to tbecross-bars jj, been' the upper ends ofthe levers E` and E into the ratchets c c.v

The operation is as follows r The shaft K, hy means of its connections with the drivingshaft M, as above described, is made to -revolve in the direction ot' the arrow, so as to cause theeccentric-wheels L L to actilpon the sectors-J Tand Jl J1 thereby producingareciprocating motion of the sliding frame I,- and producing an alternate motion of the ltop fgle-levers.

When tho eccentrics are inl the position represented in igs. 1 and 2, they press upon the sectorsJ J, and bear the frame I inwards, pressing thc levers E and E', toproduce thereby an upward motion of the'lfollower C, and bringing the levers F and Finto va position for pressing.

The sectors'J J are released from 'the e'ccentrics while the latter press upon the vsectors JJ, and drop linfo the position hcy assume in figs. 1 and 2. When the prcssing'parts of the eccent-rics reach the sectorsJ J,

which are in their lower position, into whichthey had come by their vown weight, the sectors J J have been released, und the rocking-shaft II, toA which they are connected, is turned partly aroundby thc counter-weight X, so :1s to bring thein into the position they assume in figs. 1 and 2; and an outwardmmotion is given to the reciprocating f'ram'e I by the eccentrics bearing against thc sectors'J J', end bringing vthem into the position they assume in red lines in fig. 2. i l

Whntl claimv as my invention, and desire to secure by Let-ters Patent, i's- 1. The combination nml-arrangement of the double-acting toggle-levers E E and F F with tho'followerframe D and the reciprocating frame L s-ubstantially i`n the manner hereinv described, and for the purpose specified. A. 'l 4 2. '.lhe combination and arrangement of the sectors J J 'and J J, rocking-shaftsv H'H, shaft K, and eccentric-wheels L L, in relationto eachother and to the reciprocuting frame I, toggle-levers E E' and F F', substantially as herein described, and foi' the purpose specified. l

I VIn testimony that the above is my invention, I have hereunto set'lmy hand' and' aixed my seal, this 18th dayoih/Iarch, 1868.
