As shown, a pair of spaced arms I are attached to the movable press head and` extend outwardly therefrom. The arms may be attached in any suitable manner to the press head 5 and any desirable strengthening bracing. or brackets (not shown) may be utilized. Bars or connecting members II carried adjacent their upper ends by the outwardly extending arms Ill, extend downwardly and are connected adjacent their lower ends with a platform-like part I3. The connecting members Il are shown in the drawings as round bars but they may be formed of any suitable structural members or the like and may be connected with the platform I3 by nuts I5, by Welding, or in any other suitable manner.

As the press head 5 ascends and descends the outwardly extending arms I0 attached thereto serve to raise and lower the platform I3 through the intermediation of the connecting members I I. The length of the connecting member II is preferably such that when the press head 5 is in its lowered position the platform I3 will be substantially in alignment with an adjacent floor surface,and such that when thepress head is freely elevated a fresh stack of bags or other material may be readily moved from the platform I3 into the space between the base I and head 5. In this manner stacks of material mai be readily pushed onto the platform I3 and loaded into the machine.

Preferably the connecting members II are guided during their reciprocation so that the platform I3 is prevented from freely swinging or banging about. As shown the guiding means comprises structural members I4 having slots or apertures I5 through which extend the connecting members II. The guiding members I4 may be secured to the adjacent floor by bolts or otherwise. I Y

In operation stacks of burlap bags or other materials to be formed into bales are preferably rst placed on a board 8 which has the -transversely extending slots 'I therein. The slots -1 are shown facing toward the materials to be compressed so that straps or wires may be passed through the openings in connection with tying the compressed stack together to form a bale. The upper board may be secured to and reeiprecate with thepress head 5. When a stack of thematerial is placed on a supporting board the board may be pushed onto the upper surface of the platform I3, the press head 5 then being in lowered position. As the press head 5 elevates, the outwardly extending arms III lift the connecting members II, platform I3 and the stack of material 3 to be baled and places the upper surface of the platform I3 substantially level with the upper surface 2 of the press base I. In this relationship the stack 3 may be pushed off the platform I3 and onto the upper surface of the press base. Thereafter the press head 5 descends and compresses the material for formation into bales. Simultaneously with descent of the press head 5 the platform I3 is again lowered to the floor. In this relationship another stack of material may be pushed onto the platform I3. When the press head 5 again raises the resulting. tied or strapped bale on the upper surface 2 of the press base may be pushed from the surface of the press base to clear it in preparation for receiving another fresh stack of material from the platform I3. rI'hus the lifting device .or attachment; operates entirely automa*- tically as the press head 5 ascends and descends.

While the present device is shown at only one side of the press head 5 and is particularly adapted to the elevation of stacks of materials for loading onto the press base I, it will be clear that a similar device may be provided,v if desired. at the opposite side of the press so that materials compressed and tied into bales may be pushed from the upper surface of the press base onto theadditional device for lowering. Where a device is used at each side of the press the device at one side serves to elevate fresh stacks and the device at the other side to lower completed bales of material.

The lengths of the connecting members Il, and other dimensions of the attachment device, may of course vary in accordance with the particular press. If desired each of the depending connecting members may be provided with threads I9 for a portion of its length to facilitate use with different presses and under different conditions.

It will be seen that the present invention provides a new and improved attachment or device for lifting stacks of material up to the level of a press base, the materials being readily pushed onto the upper surface of the press base for formation into bales. The device is relatively simple in construction and operation and operates automatically during operation of a baling press itself. The device is sturdy in construction and is well adapted to withstand the rough usage to which it may be subjected.

As various changes may be made in the form,

construction and arrangement of the parts herein without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention; I claim:

l. In a baling press having a base with an upper surface normally spaced a fixed distance above a floor and a head above said base reciprocable toward and away from said base for cornpressing materials between the base and the head upon downward movement of the head, a platform, reciprocable members connected with and normally extending upwardly from said platform for carrying the-platform, supporting means connected with said reciprocable members, and attached to a recprocable portion of the press and extending outwardly therefrom for reciprocating said members and thereby raising and lowering said platform, and means for guiding at least one of said members during reciprocation thereof with said head.

2. In a device of the class described for use with a baling press, a platform, a pair of arms for attachment to a movable portion of the baling press extending over said platform adjacent opposite ends thereof, a plurality of vertically movable supporting members secured to and depending from each of said arms at spaced intervals thereon and having lower portions secured to said platform at spaced intervals thereon, means for varying the effective lengths of said members to thereby adjust the spacing of said platform from said arms, and means for guiding said platform during elevation and lowering thereof comprising `members opposite ends of the platform projecting over said platform and extending atleast partly about a, supporting member. 1

adjacent-V 3. In a baling press of the class described having a base with ,an upper surface normally spaced a fixed distance above a fioor and a head above said base reciprocable toward and away from said base for compressing materials between the base and the head, means carried by' and reciprocable with said head for supporting a platform comprising rods having lengths at least equal to the initial height of a stack of material to be compressed in said baling press, and a platform supported by said means and reciprocable therewith between a platform-loading position below said upper surface of the base and a discharging position adjacent said upper surface of the base for raising materials to said upper surface by upward movement of said head.

4. In a baling press of the class described having a base with an upper surface normally spaced a xed distance ,above a oor and a head above said base reciprocable toward and away from said base for compressing materials between the base and the head, means carried by and projecting laterally from said head with respect to its direction of reciprocation and reciprocable with said head for supporting a platform, a platform below said projecting means, and support means secured to said projecting means and platform and reciprocable with the head and projecting means between a platform-loading position below said upper surface of the base and a dis'- charging position adjacent said upper surface of the base for raising materials to said'upper surface by upward movement of said head.
