1 Claim. (Cl. 100-232) This invention relates to presses and more particularly to an improved press operable to compress scrap metal or the like into compact bales.

it is an object of the present invention to provide an improved baling press which includes a gathering chain her and a ram therefor which is operable to move material deposited in the gathering chamber into the main compression chamber of the press.

A still further object of the present invention is the provision of an improved baling press having a pivoted lid operable to vertically compress the material deposited in the compression chamber.

A still further object of the present invention is the provision of a baling press having improved means for compressing material vertically, longitudinally and transversely.

Still another object of the present invention is the provision of a baling press having an improved means for discharging the compressed bale from the press.

Still another object of the present invention is the provision of a baling press which is sturdy in construction, simple in operation and economical to maintain.

These and other objects of the present invention will become more apparent during the course of the following detailed description and appended claim.

The invention may best be understood with reference to the accompanying drawings wherein an illustrative embodiment is shown.

In the drawings:

Figure 1 is an isometric view of a baling press embodying the principles of the present invention and showing the same in its initial open position;

Figure 2 is a side elevational view partly in section showing the baling press with the gathering ram fully extended;

Figure 3 is a view similar to Figure 2 showing the lid fully extended;

Figure 4 is a view similar toFigure 3 showing the longitudinal ram fully extended;

Figure 5 is a top plan view partly broken away showing the transverse ram initially extended with the discharge door closed;

Figure 6 is a view similar to Figure 5 showing the door open; and

Figure 7 is a view similar to Figure 5 showing the manner in which the compressed bale is discharged.

Referring now more particularly to the drawings, the baling press of the present invention comprises a frame 10 which constitutes a means defining a compression chamber 12 and a horizontally extending gathering chamber 14, both of which are rectangular in plan. The frame 10 includes a bottom wall 16 having a pair of

parallel side walls

18 and 20 extending upwardly therefrom and an end wall 22 extending upwardly therefrom between one end of the side walls. This end wall 22 has a height substantially less than the height of the side walls 13 and 20 and is preferably built up to have a substantial thickness. Extending between the opposite ends of the

side walls

18 and 20 in parallel relation with the bottom Wall 16 is a horizontal wall 24 which is disposed at substantially the same level as the upper edge of the end wall 22.

A lid 26 is pivoted between the side walls 13 and 28 just above the end wall 22 by means of a shaft 28 suitably journalled in the side walls. This lid includes a pair of spaced central strengthening ribs 30 to which a piston rod 32 of a ram 34 is attached. Ram 34 includes the usual cylinder 36 which is pivotally mounted be tween a pair of horizontally spaced plates 36 suitably mounted on the rear end of the end wall 22. By virtue of the pivotal connection of the cylinder with the frame and the piston rod with the lid 26, ram 34 acts to pivot the lid between an open position wherein the open top of compression chamber 12 is exposed and an extended or closed position wherein the lid is disposed within the upper portion of the compression chamber in substantially the same plane as the horizontal wall 24.

Mounted above the horizontal wall is a gathering ram unit, generally indicated at 40, which includes an angular plate d2, the vertical flange of which constitutes a material contacting panel which forms a vertical end wall or the gathering chamber when in retracted position. The forward end of a piston 44 of the ram 40' is secured to the rear surface of the vertical panel 42 and an associated cylinder as is rigidly mounted above the horizontal wall 24, as by straps d8. Ram 40 is operable to move the panel through the gathering chamber so as to discharge the material therein into the main compression chamber 12.

Mounted below the horizontal wall 24 is a longitudinal ram unit, generally indicated at 5%, which includes an angular plate 52 having a vertical panel shaped to extend within the lower portion of the compression chamber below the horizontal wall 24 so as to form a vertical end wall of the lower portion of the compression chamber 122 when retracted. A piston rod 54 is fixedly secured to the panel 52 and an associated cylinder 56 is rigidly secured to the bottom wall of the frame by any suitable means. Ram unit 56 is operable to reciprocate panel 52 within the lower portion of the compression chamber 12 in a longitudinal direction.

Extending from the side wall 1'8 is a super structure 5'3 upon which is mounted a transverse ram unit, generally indicated at 60. This ram unit includes a panel 62 disposed within an opening 64 formed in the lower portion of the side wall 13 adjacent the end wall 22 so as to form a lower side Wall of the lower end portion of the compression chamber 12 when in retracted position. A piston rod 66 is connected with the panel 62 and an associated cylinder 68 is rigidly secured to the super structure 53 in any suitable manner.

The opposite side wall 20 is likewise provided with a super structure 7t! within which a ram unit 72 is mounted. This ram unit 7'2 includes a door or panel 74 which is disposed adjacent an opening 76 formed in the side wall 26 in a position corresponding to the opening 64 of side wall 18. The door or panel 74 is longitudinally reciprocsted into and out of closed position with respect to the opening 76 by means of a piston rod 78 secured thereto and slidably mounted within an associated cylinder 80.

If desired, the entire frame ill may be supported on a 7 chamber and the ram unit 44 actuated to discharge the material therefrom into the compression chamber. After both of the chambers have received a suitable charge of scrap metal or the like, ram unit 40 is actuated (by means of suitable hydraulic controls not shown) so as to the panel 2-2 through the gathering chamber into i extended position as shown in Figure 2. In this condition, all of the material will be disposed within the compression chamber 12 and the panel 42, together with panel 52 of the longitudinal ram unit 55 constitute opposite end wall of the compression chamber.

As shown in Figure 3, lid 26 is then moved from its open position into its closed position by actuating ram unit 34. This movement of the lid 26 will effect a vertical compression of the material deposited within pression chamber. Thus, as the lid moves throu h the upper portion of the compression chamber, tl material therein will be compressed into the lower portion thereof.

Next, ram unit is actuated to move panel 52 longitudinally through the lower portion of the compression chamber, which movement effects a compression of the material therein into the lower end portion of the chamber 12. As shown in Figure 4, the ram unit 59 in its fully extended position moves the panel 52 a distance the outer limit of which is spaced from the end wall 22 of the frame. Stated differently, when the ram unit 50 is in its fully extended position, the panel 52 is disposed away from the end wall 22 a distance substantially equal to the width of the

openings

64 and 76 formed in the side walls.

As shown in Figure 5, ram unit 6% is next actuated to move the panel 62 within the opening 64 transversely through the lower end portion of the compression chamber toward the opening 76. The initial movement of the ram unit 6?; compresses the material disposed in the door 74 is closed by actuation of ram unit 72, panel as is retracted within opening 64 by actuation of ram unit 6%, panel 52 is retracted to the inner edge of the horizontal plate 24 by actuation of the ram unit 5%, panel 42 is retracted to the outer end of the gathering chamber by actuation of ram unit 4%, and lid 26 is pivoted into its open position by actuation of ram unit .34. This con dition of the press is illustrated in Figure 1.

It is to be understood, however, that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same and that various changes may be made without departing from the spirit of the invention or the scope of the appended claim.
