' and eficient means whereby the movement of the jack is multiplied to the follower during the transmissionof power from one to the other, it thus being possible, with a relatively short movement of the jack, to effect an extensive movement of the-follower in the press.

A further object is to provide a press of this character built to withstand excessive strain and which has simple but efiicient means combined therewith for reducing friction during the operation of the press.

A further object is to provide improved means for facilitating the placing and removal of the tiewires used in the formation of the bale.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention has been shown.

obliquely disposed. braces I l Figure 13 is an elevation of the rear or delivery end of the press.

Referring to the figures by characters of reference, A designates the housing or body portion of the press. This is entirely of'metal construction and includes parallel longitudinal angle beams I which are joined at the sides by parallel vertical angle beams ZprQjecting upwardly and downwardly beyond the beams I. These side beams2 have their upper projecting ends joined by top cross beams 3 while bottom angle beams extend across the structure and connect the lower projecting ,ends of the side beamsas shown as 4. Two of the top cross .beams are widely spaced to receive between them adoor 5 havingcross-beams 6 which arepivotally mounted on a rod 7 carried by the widely spaced beams which have been indicated at 3. This door is' adapted to be securely held in closed position by fingers or latch pins 8 which are offset from a rod 9 and extended parallel therewith. This rod isslidably mounted at its ends in the beams 3' and by thrustingthe rod in one direction the pins or fingers 8 will be moved into'registering openings in the door beams B and those side beams 3 adjacent to the ends thereof.

When therod 9 is slid in the oppositedirection,

however, the pins or fingers 8 will be withdrawn from engagement with theparts 3' and 6 so that the door thus can be swung upwardly to open position.

The top of the housing .or body A is closed between the outlet end thereof and the adjacent beam 3 by a top plate Ill, The space between the other beam 3' and the front end of the housing or body is open, however, but is provided with secured to the upper longitudinal beams I.

Theside beams 2 atthe delivery end of the body or housing Aiare. connected by afpivot rod 82 on which are mounted parallel angle beams l3 connected to a plate |4so as toform adoor for the .delivery end. The upperends of these beams l3. are cut away to form open corner notches I5 .and to the inner. surface .of plate I4 are joined spaced strips l6 providing wire-[receiving grooves I lbetween them.

A latch in the formofan elongated looped rod l8 is mountedat its-opposed ends in brackets I!) carried by the ends of the beam 3 nearest the outlet end of the housing or body A and this loop,

undernorinal conditions rests in the notches [5 so .as to hold the gate secured in closed position.

Theends of the grooves "lLLwhen'the gate is provided between longitudinal superposed plates 2| which are attached to the inner sides of the beams 2 and form the side walls of the body or housing A. These plates do not extend throughout the length of the housing but are spaced at one end from the front or power end of the press so as to leave openings at the sides as indicated at 22.

The bottom of the housing or body A is closed by a bottom plate 23 resting on the bottom crossbeam 4 and extending throughout the length of the press.

At the power end of the housing or body A the structure is provided with angle beams 24 having flanges extended toward each other as shown particularly in Figure 5 and these side beams 24 cooperate with adjacent side beam's'25 to hold a thrust beam 26 which is ext'endedtransversely of the body or housing between the beams 24 and 25, and approximately midway between the top and bottom of the housing. Thrust beam 26 is extended through end flanges 21 extending from a base plate 28 which is thus held to the thrust beam and on this base plate is mounted a hydraulic jack of any suitable type indicated generally at 29 and which is firmly anchored to the beam in any suitable manner. This jack is adapted to be actuated by a hand lever 30 extending through the side opening 22.

The thrust beam 26 and the beams 25 engaged thereby can be reenforced by obliquely disposed braces 3| located in the openings 22.

Slidably mounted on the side beams 2 at the discharge end of the housing or body A are angle strips 32. These strips are formed with short slots 33 in which are located guide lugs 34 extending from the beams 2 on which the strips are mounted. These slidable strips are on those sides of the beams 2 facing the power end of the body or housing A and each of them is provided, adjacent to its upper end, with a slot 35 through which the adjacent end portion of loop I8 is extended. These end portions of loop 18 are extended through elongated slots 31 in the beams 2.

Obviously when the loop 18 is in its normal or lowered position, it is seated in the notches l5 as heretofore explained for the purpose of fastening the end gate in closed position. By pulling the loop 18 upwardly so that it will swing within the slots 31, however, said loop will move about its pivotal connection with bracket 19 and will pull upwardly on the upper end portions'of the slidable strips 32. These slidable strips are provided in their inner sides with angular slots 38 which extend into the strips from their longitudinal edges and thence upwardly. When the strips 32 are in their raise-d positions, the open ends of the slots will register with the slots 20 and the grooves [1. However when the strips 32 are moved downwardly, the open ends of the slots 38 will move below and out of register with slots 20 and grooves 11 so that only the upper inner end portions of the slots 38 will register with the grooves 11. In Figure 2 the strips 32 have been shown in their lowered positions as last explained.

The follower used in the housing'or body A has been indicated at B and is of new construction. This follower includes a head 39 and that face of the head nearest the gate at the delivery end of the housing is provided with plates 40 spaced apart to form grooves 4| which register with the slots 20. Parallel angle beams are extended toward the power end of the press from the head 39 adjacent to the lower corners thereof,

these beams 42 being connected by a bottom plate 43. A pair of parallel spaced angle beams is extended toward the power end of the press from each side of the head 39 adjacent to the center thereof and cooperate to form a guideway or track. Sid-e plates 45 connect the angle beams 42 to the lower angle beams 4-4 while the upper angle beams 44 are connected by side plates 46 to parallel angle beams 41 extending toward the power end of the press from the upper corner portions of the head 39. These angle beams 41, in turn are connected by transverse and obliquely disposed cross-strips 48 which serve to brace the structure.

Angle beams 49 are located on head 39 and at the outer sides of the beams 42, 44 and 41, and

constitute side connections and reenforcing means. To each of these angle strips 49 are joined upper and lower brackets 50 each of which carries a pair of anti-friction rollers 5| and 52. The jrollers 5i bear upwardly and downwardly upon the upper and lower angle beams I respectively, while the rollers 52 bear outwardly against the side plates 20 adjacent to these beams. Thus the head of the follower is held properly centered within the housing or body A.

Brackets 53 are secured .to the center of the head 39 and pivotally connected to them is one end of a lazy-tongs 54 made up of heavy metal links. At their points of crossing these links are connected by cross-rods 55 provided on their ends with anti-friction rollers 56 arranged to travel on the guide rails or beams 44 forming the track therefor. Thus these pivotal points located where the links of the lazy-tongs cross, are all held along the longitudinal center of the press so that they will not be able to move upwardly or downwardly out of proper alinement.

For the purpose of preventing lateral displacement of the lazy-tongs, the pivotal connections between the ends of the links are provided with casters 51 which are adapted to travel along the inner surfaces of the plates 45 and 46, thereby constituting anti-friction means.

That end of the lazy-tongs remote from the head 39 is pivotally joined at 58 to a carriage 59 likewise guided along the track formed by beams 44, there being rollers 60 on the ends of the pivot member 58 and also on the'ends of another pivot member 6| joined to ithewcarriage; This latter pivot member is provided with pivoted cross-heads 62 above and below the carriage and each crosshead has its ends joined by coiled springs 63 to the anchored base plate 28 on which'the jack 29 is secured. The slidable stem 84 of the hydraulic jack is attached to carriage 59 by the pivot member BI and the free ends of the lazy-tongs ad'- ja-cent to the carriage are equipped with casters 51 as shown in Figure '1. These free endsare connected by rods 65 or the like to'the end of a strong strap 66 extended around .thebeam' 26 and held securely to the jack 29 in any suitable manner, as by means of an encircling band91.

Beam 26 has guide rollers 68 joined thereto and located between the track beams 44 sothat that portion of the follower within thepower end of the body I will be properly supported and'centered, these rollers 58 cooperating with the rollers 50 and 5| to maintain the head of thefollower B at the correct angle to the bottom of the housing A. Y Y

At any point desired the guide rollers 69 can be arranged withinthe housing A at the sides thereof for engagement with the plates 45 and .46, thereby to hold the follower properly centered transversely.

Those-side beams of-the body or housing nearest the-feed .opening and between said openi and the outlet end of the press have been indicated at 2 and they are provided on those faces nearest the door opening with angle strips 19 having slots '1! extending .thereinto and corresponding with the slots 38 and the angle strips 32. These angle strips are adapted to slide vertically on the beams 2', being held thereto by bolts 12. The angle strips 70 are normally located with the outlet ends of slots it below the level of the slots 20. By pulling the angle strips upwardly, however, these outlet ends can be brought into line with the slots 20.

Under normal conditions the lazytongs 54 is retracted to a position between the door opening and the jack. Tie-wires to be used in holding the bale under compression are inserted transversely through the slots 20 adjacent to the outlet end of the press while the gate is open, and as the loop 18 is in raised position these wires can be inserted into the slots 38. The end gate is then closed and the loops I8 swung downwardly to fasten it in place. This movement will cause strips 32 to move downwardly, thereby holding the wires in the end portions of slots 20 as shown in Figure 2.

One end of each wire is then threaded along each of the slots 29 at one side of the press until said end is brought to a point adjacent to .and inwardly from the slide 10 and the slot H therein. The other end of each wire is threaded along its slot 20 and is of such length as to be extensible later in the operation of the press, across the housing for attachment to the opposite end of the wire.

After the wires have been threaded along the housing as stated the material to be compressed is placed through the open top of the housing and into the path of the retracted plunger. The jack is then actuated by oscillating the lever 30. As the free ends of the lazy-tongs links are anchored by the rods 65, operation of the jack will cause the plunger 64 to press through pivot 58 against the lazy-tongs so as to elongate it. This will cause the head 39 of the follower to compress the material in the path thereof against the closed gate at the end of the housing and as the head 39 advances the angle beams 42, 44 .and 41 with their connections will also move therewith. This movement is effected with the minimum friction because of the arrangement of anti-friction rollers and casters mounted on the lazytongs and on the follower. When the head of the follower reaches a point between the slotted strips 10, the long ends of the tie-wires are inserted transversely of the head 39 within grooves 4| until they emerge through slots H. Here they are joined to the other ends of the wires so as to form complete loops about the bale, it being understood that the ends of each wire are to be drawn tightly together as they are fastened. Strips 19 are then lifted so as to become released from the twisted wires and permit them to recede into the slots 29. Thereafter loop I3 is swung upwardly. This lifts the strips 32 so as to release the engaged wires and at the same time the gate is released so that it can swing downwardly. By-

then again actuating the jack, the lazy-tongs will be further extended to expel the finished bale from the press.

The lazy-tongs and the follower connected thereto are then retracted to the initial position and the foregoing operation is repeated. This is done by releasing the compressed fluid within the jack and allowing the springs 63 to pull upon the lazy-tongs and, cause them to contract and draw the head 39 toward the jack. Obviously during this action the links or rods .65 will swing apart.
