Application filed March 22,1884. Serial No. 125,163. (No model.)

and to which the team is hitched for moving To all whom, it may concern:

Be it known that I, GEORGE ERTEL, of the press to and from the place of use. Quincy, in the county of Adams and State of B is the feeddoor, strongly hinged atits one Illinois, have invented a new and Improved vertical side, and so as to close an opening in 5 Hay-Press, of which the following is a full, the side of the press-case through which the clear, and exact description. hay, straw, moss, or other material to be The object of my invention is to provide a baledis passed into the pressin front of the folmachine of improved construction for pressing lower 0. hay, straw, moss, cotton, or other materials B is a table fixed at the side of the press. 10 into bales of uniform density.

Fig. end, and preferably between two arms, D, 7 is a sectional elevation on the line 00 .90, Fig. which in turn are pivoted on a strong bar or 5 5 6; and Fig. 8 is an enlarged transverse section shaft, E, held in the press-frame. Butone on the line 3, r Fig. pivoted arm D may be employed;but by using Aindicates thcprcsscasabuiltnpofstrongly two, or one at each side of the sweep-head, a framed and bolted timbers, and mounted by a stronger pivotal connection with the lever D swinging forward axle, A, andfixedhind axle, at (I may be made, and the action of the sweep [00 50 A on wheels A, and having a tongue or draft as pivoted between the arms is better balanced connection, A3, coupled to the forward axle, and more effective.

On the bar E, between the arms D, is pivoted the three-armed metallic head'E, to which 7 the side bars, e, of the sweep F? are pivoted by a rod or bolt, 6, so that the outer end of the sweep may be adjusted higher or lower to suit the animals working it. The sweep is supported from the press-frame by a brace, E, which has an eye, 6 engaging the pivot-bar E loosely, and at the other end the brace is screw-threaded and passesv freely through a cleat, e, fixed at the outer end of the sweep, a nut, 6, being screwed onto the brace at the outside of the eleat, so that by adjusting the nut along the brace the outer end of the brace may be adjusted as to height. A nut, e, may be used at each side of the brace e, if desired. A collar, 0', holds the brace up at the inner end to clear the press-frame as the sweep swings from side to side in working the follower, as hereinafter described. Plus or equivalent devices may be used in place of the nut or nuts e", if desired. By this construction the pivotbolt will not be subjected to so great wear as whenthe sweep is rigidly connected.

To connect the sweep E with the followerlever D, I employ an open or slotted bar or link, F,which is held by pinsff, respectively, in the slotted outer end of the lever D and in the slotted end of the rear arm, c, of the sweep: head E,which connection, by its articulations, permits the follower to be moved for the first part of its instroke by the direct pull of the link by the sweep, and enables the-link to slide freely on or over the pins ff as the side arms of the sweep-head bear directly on the extreme outer end of the lever D to apply the power by direct contact of the lever and head toward the end of the stroke of the follower when the strain is greatest, or the link F maybe of such length as to pull the lever D over or past the longitudinal center ofthe press without a contact of the sweep-head with the lever, as above described; and the link-connection also permits the outer end of the lever D to be projected to the side of the press (as the follower is fully drawn back) opposite to that from which the sweep extends, so that the parts are in position for a direct pull on the link by the sweep as the horse starts to pull the sweep to the other side of the press in making a full instroke of the follower C, and as the outer end of the lever D may freely be swung to either side of the press, a full inward stroke of the follower may be made as the horse pulls the sweep in either direction, so that no time is lost by a return of the horse and sweep to the opposite side of the press before the next instroke of the follower can be made. Other particular advantages of these connections of the follower with the sweep are that they perwit the press to be made much shorter than with other constructions, and also lighter and cheaper, meanwhile increasing the smoothness of working and general efficieney of the machine, and the power is applied in a simple and direct manner, which allows merchantable bales to be made with a pull of the sweep by a single horse.

The slots in the ends of the lever D and the arm 6'' of the head E for receiving the link F extend backward by angular grooves to the opposite edges of the lever and arm, as at d, to allow the requisite play of the link.

A lever, G, pivoted to the press case at 9, extends across above the lever or pitman D to the opposite side of the press, said lever Gbeing notched to drop automatically upon the lever D to hold it by the notch when the follower completes its last instroke on a bale, and a looped cord, chain, or hook, g, is-provided to hold the lever G clear of the lever D when the follower is to be drawn back (after tying the bale) and in position for pressing the first charge of the next bale.

In order, further, to shorten the press and to provide for pressing the successive charges of hay with a like pressure to insure a uniform compactness of the pressed bale from end to end, I provide in thepress-case or balingchamber a movable head-block, H, having a,

strong beam, H, which projects outward through the end wall of the press, and preferably through a metal socket or box, I, fixed to the case, on the bottom of which box rests a notched metal block, J, of sufficient length to form a bearing on which the beam H may slide, and between which block J and a gripblock, K, the beam may be clamped to hold the head-block H against the pressure of the follower, the block bearing down against the incline or shoulder h, formed in or on the upper surface of the beam H. (See Figs. 3 and 7.) The block J may be held detacliably in position by dowel-pins instead of a notch.

The grip-block K has a rounded top, which has a bearing in a correspondingly-shaped seat in a block, L, and so as to rock therein in the direction of the length of beam H for riding up and down and bearing firmly upon the incline h of the beam, the rocking block K accommodating itself to the top surface of the beam. On the block L, and inside of the outer plate, 1, covering the upper part of the box I, is placedta rubber springblock, M, be tween which and the top of box I a key or wedge, N, passes through apertures or slideways in the sides of the box, the top of the box being adapted to the key. (See Fig.6.) \Vhen thekey N is partly withdrawn, the parts M L.

K are free to be lifted in the box I, while the block K rides up the incline h of beam H as the head-block II is carried to the end wall of" place in box I, below the beam H, as shown,

IDC

IIO

the top of block L will rise above the lower end of the plate 1, to hold the gripping devices K L M in the box I and secure against displacementby the movements ofthe beam H.

It is evident that the rubber spring M may be substituted by any other style of spring made of metal or other material, and that for the single purpose of securing thebeam H, by the grip-block K acting on an incline or shoulder of the beam, all forms of springs may be dispensed with; but I prefer to employ a spring, as it permits the parts in box I to yield gradually within fixed limits to the compressive strain on the head-block H, and thereby protects the gripping devices from sudden hurtful shocks or strains while the head-block is held in the forward position by its incline h for the pressing of the first charge or charges of material by the follower O, and while the last charge of material for a bale is being pressed the head block H will rest fairly against the end wall of the press, as in Fig. 5, and the grip-block K will rest loosely on the inclined shoulder h of the beam H, and the beam-gripping devices will then be entirely relieved of strain, whether the key N be loose or be driven tightly to place in its slideways in the box I.

Theinclineh ranges upward and inward, so that the tightened grip-block K resting there on shall resist the outward movement of the headblock H, and the incline h ranges downward and inward to permit the gripping de vices in box I to ride up or swing over this incline easilfy as the head-block H is pushed inward by hand to carry the incline it under the grip-block K in position for locking the head-block in place prior to compressing the first charge of material for the next bale.

Other equivalent mechanical means may be used to press the grip'block K L upon the beam H forleeking the head-block H in place, as above described, such as a screw or cam working in the box I; but the key N makes a simple, reliable, and ensllyworked device for the purpose. The key N could be driven tightand loose, to grip and release the beam H, by using a hand mallet or hammer; but I have connected the key by a pivot, a, at its end with a rod, 0, which connects with the baledischarge door P at 0, and in such relation to the hingebolt p of the door that when the door is thrown open the rod will act to withdraw the key N automatically for loosening the hold of the grip-block K upon the beam H of the headblock H, and so that when the door P is closed the key N will be forced in by the pull of the red O to bind the grip-block or device on the beam at h. This operation, by the door 1?, of a gripping device to bind and release the head-block beam is an important feature of my invention, and the rod 0, or equivalent device, may connect with any mechanical equivalent of the key N-snch as a cam or a screw of large pitchto bind a grip device on the beam and release it therefrom by the. movement olthe door,and still be within the scope of this part of my invention.

In the press described in my said Patent No. 261,823 the slack side of the baling box or chamber was bound fast and released by the action of inclines fixed at the outer closing edges of two opposite hinged doors upon inclines along the back edges of the said slack side.

In thepresent llllPlOYQlllGllh Ihave arranged to work the slack side of the baling box or chamber by the action of the single door P, hinged at one side of the presscase, thereby considerably reducing the cost of the press and the labor of working it. The slack side It of the balingbox being in this instance the top side of the box, I suspend it so as to have a limited vertical play by a bent or headed bar, 7, at the inner end from one of the crossbolts of the press-frame, and at the other end by a plate, 0', of considerable length, fixed transversely to the upper face of slack side It and overhanging it, so as to support the slack side by a rest of the plate 9" on a cross cleat or bar, r, of the press-case, and with a long bearing to prevent that end of the slack side nextthe hinge p of the door P from rocking laterally, and thereby insuring the true entrance of the beveled plate or block S, fixed along the upper inner edge of the door 1?, over the incline or bevel T, formed along the upper front edge of the slack side R, as the door 1? closes. (See Fig. 8.) Over the inner er 0pposite edge of the side It, I fix to the frame a strong timber or plate, U, leaving a space between plate U and side It, in which a wedgeblock, V, may enter. The wedge V is fixed to bars V, which pass outward through the frame and have heads 1) on them to be struck by the bars or cleats W, fixed to the door 1, as the door closes, to force the wedge V inward to bind the slack side R fast along the back edge, while the block S rides upon incline T to bind its front edge, as shown. Springs 8 force the wedge V back and loosen it when the pressure on the bars V is released by opening the door 1?, and stops t are provided on the slack side R to act against the press-frame to prevent pulling. the side R- outward or withdrawing the wedge V, the outward movement of which wedge is limited by its contact with a stop, a, fixed on the side R.

A hinged loop or link, X, on the frame A is I to be passed over an iron stay-bar, Y, on the door I? to lock it closed. Pivoted hooks Z on door 1? are thrust inward by springs z to hold the pressed material from unduly expanding when the follower G is carried back to admit the next charge of hay for a bale to the press, and when it is fully driven back the followerstrikes the rubber or other elastic buffers 0', set in the pressframe to relieve the shock.

The side of the balingbox opposite the door I is slotted, as at a, and in horizontal alignment with the face slots of the head-block and follower, to permit the passage of the ties IFO around the pressed bales when the said door is opened.

The operation of the press is a follows: The machine rests on its wheels A when at work, the sweep E being attached at e and adjusted for height by the nut e, as above described,; to suit the horse now hitched to the sweep. The door P being closed, theslack side R will be wedged fast against outward pressure, and the grip block K will be clamped by the entered key N upon the incline h of the head-block beam H, the head-block H being in the inward position shown in full lines in Fig.3. ThefollowerOhavingnowbeendrawn or pushed outward by hand at the beginning of the pressing, as in Fig. 3, and the sweep E set at about a right angle at one side of the press, as in Fig. 4, the lever D will have carried the arms D about in line with the center of the sweep, and the opposite ends of the link F will rest against the pins or bolt-s ff. The

lever G- being now held up free of the lever D by the loop or hook device 9, the first charge of hay or other material for abale is fed to the press-case between follower O and head block H, and the feeddoor B then closed and fastened, which draws the lever a by cord b to the position shown in Fig. 4, the inner end portion of the cord being slack, as shown. The sweep will now be drawn from the position shown in Fig. 4 toward that shown in Fig. 5, and in starting, the pressure will come on the link F and the boltsff', and the arms D are gradually swung around toward the left hand on bolt E. The link F is of such length that when the extreme outer end of the lever D at f is drawn inward and laterally to a point about in line with the right-hand side of the press-case the head E of the sweep will strike the end at f of lever D at about the point shown in Fig. 5, and as the movement of the sweep continues, and for about the last quarter of the instroke of the follower, when the compression increases, the strain is transferred from the link F and bolts ff to the pivotal connection of the arms D with the shaft E, and with the lever D at d, the sweep and the lever being pivotally tied together at said points E d, while the back of the sweephead acts directly on the extreme outer end of lever D to complete the instroke of the follower, the link F then running out freely at one end from the bolt f, as in Fig. 5. At about this time the lever a will be drawn upon by cord Z) to unlatch and open the feed-door B, and the end at f of lever D will be forced over slightly beyond a straight line connecting the pivot-points E cl, or beyond the center, whereupon the follower O and its lever D will instantly be free and will be forced backward or outward by the partial expansion or reaction of the pressed material in the baling box, the link F swingingaround freely on the bolt f as a center, while the lever D, arms D, and link F are carried automatically to assume the same relative positions at the baledischarge side of the press, with the sweep E toward the feeding side, as they occupied in starting, andin readiness to again force the follower inward on the return-stroke of the sweep. The action of lever D will be the same if the link F is only of a length to carry the lever over the longitudinal centerline of the press without a contact of the sweep-head with the end of the lever, as will readily be understood. As the follower O is carried back against the buffers c, the hooks Z hold the pressed material from unduly expanding. The door P is now opened, which simultaneously releases the slack side R of the baling-box and the grip of the block K on the beam H of the head-blockH, the loosening of the slack side also serving to loosen the head-block. at its edges, so that the head-block may easilybe drawn backward, the block K then riding freely up the incline h,and finally dropping into the recess h as the rear side of i the head-block strikes the end of the baling box. The door P is now closed and locked, which again fastens the slack side R by the wedges S V, and the second (and in this lll-' stance the last) charge of materialfor a bale is fed in at the door 13, which is then closed and locked, and the sweep is drawn back on the return-stroke. The action of the power apparatus in driving the follower inward, as above described, is repeated; but the notched lever Ghaving now been released to rest upon the lever or pitman D, it will lock by gravity over the lever as the lever reaches the central position and hold the follower O in its extreme inward position while'the door P is again opened to release the slack side It and permit the bale to be tied and discharged from the press, the discharge of the bale being easily effected, as the slack side R prevents a wedg ing of the bale in the baling-box in substantially similarmanner as described in my aforelVhile the door P said patent, No. 261,323. is open and the wedgeN thereby is withdrawn, and after discharge of the bale, the head-block H is again pushed in by hand to carry the incline h of beam Hbelow the grip-block K, as in Fig. 3. The door P is now closed, to secure the slack side R, by the wedges S V,and to grip the beam H by block K,and the lever G is raised from lever D and the follower pulled back with the parts of the power apparatus again set to the positions shown in Fig. 4, when the first charge of material for the next bale maybe fed to the baling-box and the work proceed as before described.

It will be understood that two or more inclines like the one it may be formed in or on the beam H back of the recess or incline h, so that severalcharges of hay or other mate rial may successively be pressed with the head-block H held in position by the action of the grip-block K on the successive inclines h, and in this case the said inclinesh will have a reverse side or face or be in shallow V form to permit the block K to rise upon the beam as the successive inclines h come into position tobe clamped at the inner sides or faces by the block K, and the lock-lever G will be allowed to engage lever D only when pressing the last charge for a bale, as above described My improved press isfroniiive to eighteen feet shorter than other presses making bales of the same size and weight, the total length of the presscase, including the power apparatus, (except the sweep,) being only about eleven feet; and the weight of my improved press is from five hundred to fifteen hundred pounds less than other presses for like work. Consequently the machine may be handled and hauled over rough and crooked roads with greater facility; and my improved press may also be built more cheaply. Ithas ample power to do its work efficiently, and is durable in use.
