T0 all whom Ait may concern,.-

Be it'known that I, CHARLES L. MILLER, a

citizen of the United States, residing at Berkeley. in the county of Alameda and State of California, have invented new and useful lmprovements in Ealing-Presses, of which the following is a specification.

My invention relates to Vimprovements in baling-presses, and especially that class which is designed for baling-hay and like substances.

It consists in the combination and arrangement of parts and in details of construction, which will be vmore fully explained by reference to thel accompanying drawings, in which- Figure l is a side elevation of my press with follower up. Fig. 2 is a. front elevation of same with follower partly down. Fig. 3 is a rear elev'ation'of same with follower down.

Fig. 4 is a plan view of eccentric wheel and direction-pulleys. Fig. 5 is a viewi-ofreccentric wheel. Flg. 6 1s avlew of incline. Fig. 7 1s a horlzontal transverse section through baling-chamber, swing movable side plate.v

Fig. 8 is a top plan view of power end.

My invention is especially designed to be used in that class of presses lhaving a vertical press-box with a means for delivering charges of material into the upper part of the box, these charges being successively compressed by means of a follower which is moved downward by suitable connections, so as to compress the charges successively into the lower part of the press-box, and-when the bale has been completed and tied it is removed through a door-opening which is 'located below the point'at which the material is delivered into the'press. f

fAs shown in the drawings, A is a verticallydisposed press-box of sufficient height having a follower 2 substantially filling the interior ofthe box transversely, said follower having a bar with stout ends projecting through vertical slots or channels 3 in the narrow vertical sides of the press, so that, levers 4 may be connected with these ends and power applied to draw the follower down after a charge has been placed within the press-box and beneath the follower. rlhe connections for this purpose consist of lever-arms 5, having their inner ends strongly fulcrumed to the press-box, as shown at 6, and the outer ends connected with the levers 4, as shown at 7. Chains 8 connect with the ends ofthe levers 4, passing downwardly and inwardly therefrom to the bottom of the press, where they pass around guide-pulleys 9, thence around direction-pulleys 10, and the two chains unite and are suitably` connected with a lrod 11 of suflicient length to extend to the end of the horse-power frame 12, where it is connected with achain 13,v and this chain is adapted to windaround y an eccentric pulley 14;

The rst downward movement of the follower and while the charge to be pressed is loose is comparatively rapid by the direct action of the chains pulling downwardly 'upon the levers 4; but as these levers approach the sides of the press the movement of the lever 5 in an arc about their pivot-point 6 will bring them-more nearly into line with the levers 4,v

and this produces a compound lever action of `less speed and greater power toward the end of the compression. At the same time the ec. centric is in'such position that its larger curvature outside of its fulcrum-sh'aft 15 will act,

through the chain, rapidly upon the levers and follower, and as the follower approaches' the bottom and the compression is nearly complete the smaller portion of the eccentric arrives beneath the chain, thus giving the greatest amount of power. tov compress the bale.

The upper or vertical portion A of the press is preferably hinged to :the stationary base-timbers 16, as shown at 17, so that the press-box may be turned down to lie in a hori? zontal position for transportation, and the Adirection-pulleys l0 being journaled in the base-timbers will not be vmoved or affected by the' turning down or up of the press-box.

The eccentric or power wheel has -tiXed to ita stop 18 in such a position that when the sweep 19, to which the team or other power is attached, arrives at a certain point during its revolution it causes the stop 1'8 to engage the lever '20, to which the end of the chain 13 is attached, and the further rotation of the eccentric windsthe chain around said eccentric, and thus -aets through its connections upon the follower, as previously described. When the compression has been completed, the end of the lever 2O rides up on an incline 21, which is in the line .of movement of the lever, and the end of the lever 2() is thus raised suliiciently to disengage it from the IOO.

IOS'

stop 18 and allow the lever to be turned backwardly. This backward movement is effected by the engagement of a lug 22, which is carried by the sweep with a lever 23, the inner end of which is eccentrically pivo'ted to the frameabove with the eccentric'14, as shown at 24. This engagement ofthe arm 22 with f the end of the levei 23 acts through a chain 25, which is connected with the lever 23, to raise the follower. The chain 25 passes around a direction-pulley 26 at the base of the press-body. Thence a chain extends upwardly and at a suitable point is divided into two chains 25lrl which )ass over direction- )ulleys 27, and the chains 25n pass thence down to the junction of the follower-actu'atin g levers 4 and 5. so that the pull upon the chain immediately acts to raise these levers and with them the follower. As the lever 20 is now released by reason of the disengagement of said lever from the stop 18, it will be seen that the eccentric is free to return about its pivotpost l5, and thus allow the chain 13 to unwind and the chains 8 to be extended in unison with the upward movement of the follower. As the lever 23 is eccentrically attached, as shown at 24, the continued movement of the sweep 19 will cause the lug or hook 22 to gradually nieve outward beyond the end of the lever 23, so that by reason of the eccentric attachment of the lever 23 this lug 22 will be disengaged therefrom and leave the lever and its chain connection with the follower-levers free to move in unison with the movements of the follower, when the latter is again depressed. VIn this manner the follower is alternately drawn down by the power communicated through the sweep to the eccentric 14 and is released and again raised to allow another charge to be placed beneath it.

The incline 21 is pivoted or otherwise made conveniently movable, so that when the last charge to complete the bale has been placed in the press this incline may be swung out of line of the lever 20, and the latter not then beingI raised and disengaged it will be seen that the follower will be held down by the power applied tothe sweep and can remain in this position until the cords or wires by which the bale is secured have been passed around the bale and tied. Then the lever 20 may be raised by a hand-bar or otherwise and the parts disengaged. The incline 21 being swung back to its normal position, the parts will be in readiness to press another bale.

The successive charges of material which are compressed by the descent of the follower are prevented from again rising by the usual hinged retainers, which consist of bell-crank latches 28, pivoted so that their points project into tlie interior of the press. These latches are freely movable in one direction to allow the material to pass downwardly, but are Weighted or otherwise arranged to return and project above the material as soon as it has passed and to hold it in place while the follower is again being raised.

In order to discharge a completed bale, a door, as 29, is hinged upon the side of the press-box opposite the position of the compressed bale and is held in its closed position by means of a swinging bar 30, hinged to the l side of the press and adapted to pass over the outer end of the door after it is closed.

In order to free the bale and allow it to be easily removed from the press-box, l have shown the following arrangement: It is desirable that the bale should be rectangular` and for this three sides of the press-box provide. The other side 31 is beveled or inclined so that the space is wider next the dooi than toward the opposite side. Across this space is a heavy piece of boiler-plate 32, one edge of which is pivoted or loosely held, as at 32', in the side of the press opposite the door-opening. The door carries an edge plate, as at 33, contiguous to its hinge 34, and this edge plate passes beneath or behind the plate 32 when the door is closed, and this holds the plate 32 substantially at right angles with the sides of the press-box and forms a rectangular chamber for the bale. As soon as the door is opened the removal of the plate 233 from beneath the plate 32 allows the latter to swing and lie against the inclined side 3l, so that the pressure upon the bale will be relieved suiiiciently to allow it to be withdrawn from the press.

The material may be supplied to the press by means of a hay-fork and derrick or other device, through the aid of which the material may be deposited upon a platform 36, conveniently disposed with relation to the door 3T, through which the supply is delivered into the press-box. This door is hinged at the bottom, as at 38, and its upper outer edge is thus allowed to turn in a ipiadrant, so tliatit opens outwardly and downwardly, and the charge may be delivered into the press through the opening which the door serves to close. Then the charge has been placed in the press, the door is closed by a pull upon the chains 39. These chains have one end connected with the door near the inovable edge. They pass thence around guidepulleys at 40, which aie located iii such position with relation to the door that the pull upon the chain will be substantially at right angles with the movement ol the door. Thus the door may be closed against any pressure of the material which is contained within the press-box. From the pulley 4() a chain leads over a pulley 41, journaled on the follower, so that the upward movement oi the follower will pull the chain and close the door, and its downward movement will slacken the chains and release the door.

41L is an attachment for the end of the chain and is movable up or down to insure the proper closing of the door.

43 is a latch or latches fulcruined so as to engage the edge of the door when it is fully closed. These latches are pressed downwardly by springs 44, so that they will antomatically engage the door when closed. vIn

i order to open these latches, they have arms projecting from opposite sides of the fulcrumlOO llO

vpoint 45, and to these arms are connected chains 46. The lower ends of lthese chains are connected with levers, as 47, which project intothe line of the'sl'ot or channel 3', in which the follower` end s move, 'so that as the follower moves downward to compress the charge which is within this portion of the press it` engages and pulls upon the levers LL7,thus

tilting the latch and releasing the door 37, which can immediately fall outward'and bc ready for another charge, while the follower continues its downward motion to complete the compression of the charge.

The plate 33 is securely bolted tothedoor 29 and moves with it, so that the opening or closing ofthe door' will move the plate82 automaticallyand without other care or attention. i i
