- the present invention relates to baling presses and more particularly to horizontal presses for baling sheet metal scrap.
- Horizontal baling presses of the character described generally comprise a rectangular chamber into which scrap to be baled. is thrown, a cover longitudinally slidable ofthe chamber into and out of covering relation with a materialreceiving opening in the chamber, and one or more platens in the chamber for compressing scrap metal therein. when the cover is in closed position.
- the general arrangement is to provide. two platens, one moving longitudinally of the chamber and a second one moving crosswise of the chamber after the longitudinally moving platen has travelled its complete course.
- the resulting bale has a width and depth as determined by the the chamber to the cover. from the foregoing description that the bales thus formed are compressed in the direction of their width and depth, but not in the direction of their height. Accordingly, the resulting bales are not as dense as they might be if they were compressed in the direction of their height.
- the aforementioned type of baling press is provided with a cover which as it traverses the opening of the compressing chamber into closing relation therewith, is so supported that it is inclined with its leading edge higher'than its trailing edge, the leading edge being yieldingly elevated so that when the cover is in closing relation with the opening of the chamber, the leading edge of the cover may be forced downwardly into the chamber to swing the cover downwardly to compress the material therein in a direction of the height of the bale to be formed.
- the result of traversing the cover across the baling chamber opening while in an inclined position is that more loose scrap may be disposed in the chamber prior to baling and therefore, with the benefit of the vertical compressing a denser and heavier. bale is produced.
- Another feature of the present invention is to provide an ejecting structure for finished bales.
- Another object of the invention is to provide a scrap metal baling press of the character'depresent invention is to provide press or the like'with a cover, which is elevated above the subsequently movable into with material in the com scribedwith wheeled supporting means whereby the cover for the compressing chamber may be moved from a position at one side of the com pressing chamber opening across the opening into closing relation therewith, the wheeled supporting meanshaving means for resiliently elevating the leading edge of the cover while the same is being moved across the chamber opening and for subsequently moving the leading edge downwardly into compressing relation with material in the compressng chamber.
- a further object of the invention is to provide a scrap metal baling press or the like with a bale ejector selectively operable upon the return of the compressing chamber cover to its open position.
- a still'iurther object of the invention is to provide a scrap metal baling press or the like with an ejector for bales formed therein which coinprises a shelf outlining a portion of the compressing chamber and on w oh the bale is formed.

14 Claims.
The present invention relates to baling presses and more particularly to horizontal presses for baling sheet metal scrap.
Horizontal baling presses of the character described generally comprise a rectangular chamber into which scrap to be baled. is thrown, a cover longitudinally slidable ofthe chamber into and out of covering relation with a materialreceiving opening in the chamber, and one or more platens in the chamber for compressing scrap metal therein. when the cover is in closed position. The general arrangement is to provide. two platens, one moving longitudinally of the chamber and a second one moving crosswise of the chamber after the longitudinally moving platen has travelled its complete course. The resulting bale has a width and depth as determined by the the chamber to the cover. from the foregoing description that the bales thus formed are compressed in the direction of their width and depth, but not in the direction of their height. Accordingly, the resulting bales are not as dense as they might be if they were compressed in the direction of their height.
According to the present invention,the aforementioned type of baling press is provided with a cover which as it traverses the opening of the compressing chamber into closing relation therewith, is so supported that it is inclined with its leading edge higher'than its trailing edge, the leading edge being yieldingly elevated so that when the cover is in closing relation with the opening of the chamber, the leading edge of the cover may be forced downwardly into the chamber to swing the cover downwardly to compress the material therein in a direction of the height of the bale to be formed. The result of traversing the cover across the baling chamber opening while in an inclined position is that more loose scrap may be disposed in the chamber prior to baling and therefore, with the benefit of the vertical compressing a denser and heavier. bale is produced. Another feature of the present invention is to provide an ejecting structure for finished bales.
An object of the a scrap metal baling the leading edge of trailing edge and is compressing relation pressing chamber.
Another object of the invention is to provide a scrap metal baling press of the character'depresent invention is to provide press or the like'with a cover, which is elevated above the subsequently movable into with material in the com scribedwith wheeled supporting means whereby the cover for the compressing chamber may be moved from a position at one side of the com pressing chamber opening across the opening into closing relation therewith, the wheeled supporting meanshaving means for resiliently elevating the leading edge of the cover while the same is being moved across the chamber opening and for subsequently moving the leading edge downwardly into compressing relation with material in the compressng chamber.
A further object of the invention is to provide a scrap metal baling press or the like with a bale ejector selectively operable upon the return of the compressing chamber cover to its open position.
A still'iurther object of the invention is to provide a scrap metal baling press or the like with an ejector for bales formed therein which coinprises a shelf outlining a portion of the compressing chamber and on w oh the bale is formed.

Referring particularly to Figs. 1 and 2 of the drawings, the reference character I indicates in general a frame in which is provided a compressing chamber 2, having side walls 3, a bottom 4, and an end wall 5. The chamber 2 is provided with an open top closable by a cover 6. For the sake of simplicity of illustration, the side members 3 and the cover 6 have been shown as thick solid members. However, it will be understood that these parts of the construction may be constructed of structural members and sheets or otherwise, if desired.
The end of the chamber 2 opposite the end wall is constituted by a platen movable under the action of a piston rod 8 actuated by a piston 9 in a hydraulic cylinder Hi. In one of the side walls 3 adjacent the end wall 5 is a second platen shown in Fig. 1, and actuated by a hydraulic cylinder and piston assembly l2, disclosed in Fig. 2. It will be understood that the platen I moves at right angles to the direction of movement of the platen 1.
Supported by the frame I is a reservoir l3 for hydraulic fluid and on the top of the reservoir l3 is supported a pump M. In front of the reservoir I3 is an operators platform l5. Suitable remote controls, not disclosed, are supported adjacent the operators platform |5 for enabling an operator on the platform |5 to control the movement of the various operative parts of the baling press.
The cover 6 is supported at its rear end by wheels 20, riding on the top of extensions 2| of the side walls 3. Appropriately supported above the paths of the wheels 20 are bars l3 which serve to prevent the rear end of the cover 6 from lifting during operation. At the front, the cover 6 is resiliently suspended from a carrier 22, provided with wheels 23, which ride on the top of plates 24, secured to the tops of the side walls 3 and having the inside edges thereof in vertical alignment with the inside edges ofthe walls 3. The plates 24 serve as loading platforms to facilitate the loading of unwieldy pieces into the compressing chamber 2 and their inner edges constitute short vertical extensions to the side walls 3. When the cover 6 is at the extreme right position, as viewed in Fig. 1, the opening of the top of the compressing chamber 2 is completely uncovered. In all positions of the cover 6, its rear portion is supported by the wheels 26 in such a manner that it is disposed between the side wall extensions 2| and guided thereby. Furthermore, as the cover 6 is traversed across the opening of the chamber 2, it is guided by the side wall extensions 2| or the side walls 3 and is maintained in an inclined position as shown particularly by the dotted position of the cover 6 in Fig. 1.
The carrier 22 for the cover 6 is in the form of a housing having suspended from the top thereof rods 25. To the lower ends of the rods 25 are connected stops 26. About the rods 25 are disposed helical springs 21, resting on the stops 26. Projecting upwardly from the top of the cover 6 are a pair of U shaped brackets 28, having openings 29 in the top thereof, through which the rods 25 project. The helical springs 21 are arranged on the parts of the rods 25 which are beneath the openings 23. The U shaped brackets 23 each have one leg 32 thereof provided with XIII-XIII of 3. turned over foot 3|, shown particularly in Fig. 5, which is secured directly to the top of the cover 6. The other legs 30 of the brackets 28 are secured to the upstanding leg of the angle bar 33. shown in Figs. 5 and 11 which is in turn secured to the top of the cover 6 and extends thereacross as shown in Fig. 11. The effect of the brackets 28, the rods 25, and the springs 21 is to resiliently suspend the cover 6 from the top of the carrier 22.
Secured to the top of the carrier 22 are two pairs of ears 34, and secured directly beneath the ears 34 to the angle bar 33 are two pairs of cars 35. Pivoted between each pair of ears 34 about pins 36 are toggle bars 3'! and pivoted between each pair of ears 35, about pins 38, are toggle bars 39. The toggle bars 31 and 39, respectively, are pivotally connected by pins 40. The toggle bars 31 are provided at their inner ends with forks 4|, between which the toggle bars 39 are pivoted. Also pivoted between the forks 4| and to the pins 40 are links 42. The links 42 are also pivoted to the ends of a bar 43, shown in Figs. 1, 3 and 6. Extending through the bar 43 is a piston rod 50, actuated by a piston 5|, in a hydraulic cylinder 52.
The piston rod 50 extends through an opening 53 in one side of the carrier 22 and is guided for axial, sliding movement in a bearing sleeve 54, secured in the opposite side of the carrier 22. In order to prevent the bar 43 from oscillating about the axis of the piston rod 50, a conventional key and keyway arrangement, not shown, disposed between the rod 50 and the carrier 22 may be employed or some suitable structure may be provided such, for instance, as shown in Fig. 9 and described hereinafter.
Longitudinal movement of the piston rod 50 is transmitted to the bar 43 by a collar 55, consisting of a pair of nuts fixed to the piston rod 50. The bar 43 is resiliently held against the collar 55 by a helical spring 56, disposed about the portion of the piston rod 50 between the bar 43 and the bearing sleeve 54. Since the toggle bars 39 are connected through the ears 35 and the angle bar 33 to the cover 6, the spring 56 as the result of its collapsing action on the toggles will tend to assist the springs 21 in resiliently suspending the cover 6 from the top of the carrier 22.
The cover 6 is moved from open to closed position through the toggles comprising the toggle bars 31 and 39 by the piston rod 50. The toggles remain collapsed as shown in dotted outline in Fig. 1 and in Fig. 6, and the forward end of the cover 6 is relatively above the rear end, as shown in dotted outline in Fig. 1 for all cover positions except in final baling position. It will be understood that as the cover 6 moves either to the right or to the left, as viewed in Fig. 1, a portion of the cover 6 will be disposed either between the extensions 2| of the compressing chamber sides 3 or between the sides 3 so that the cover 6 is guided by the sides 3 or the extensions 2| for straight movement.
, The frame I is provided at the left end, as viewed in Fig. 1, with a pair of standards 51, secured to the plates 24, and tied together with a bar 58. Connected to the standards 51 are vertical stops 59 for limiting the leftward movement of the carriage 22 under the action of the piston rod 50, as shown in Fig. 1. Also secured to the standards 57 are horizontal stops 60 reinforced on their upper sides with gusset plates 6|.
In operation, after the compressing chamber collapsed due not only to the action of the spring movement the compressing chamber 2, the carrier 22 is provided at each side thereof with a pair of vertically. extending spaced bar members 6'2. disposed between the pairs spectively, are guiding bars 64, which are in turn secured, 3 and 5, to the U shaped brackets 28. The guiding bars 63 and pairs of bars 62 also constitute a driving connection between the carrier 22 and the cover 6 to work with the toggles in transferring pushing r pulling action from the carrier 22- to the cover 6 When the carrier 22 closing direction by the rier 22 at the end of its path of movement abuts against the vertical stops 53 and stops under the horizontal stops 63. At this position the cover 6. is in full closing relation with thecompressing chamber 2; the result of carrier 22 abutting against the stops 59, continued movement on the piston rod 50 to the left will cause the toggles comprised by the toggle bars 3'! and 39 to straighten out as shown in full lines in Fig. 1. Since the carrier 22 is is moved to the left in piston rod 56, the carcenter positions.
Th of the toggle bars 37 and 39 should be so arranged that when in straight or dead center position the cover 6 will no longer be inclined as it was when the toggles were collapsed, but will be parallel to the bottom e of the compressing chamber 2. The cover is held in this position while the platen i is moved to the left into alignment with the nearest edge of the platen H, and then the platen H is moved laterally across the compressin chamber 2 to complete the formation of the bale. Since the baling press,,according to the present invention, is designed for baling sheet metal scrap, it is not necessary to provide any arrangement for tying the compressed material together as the parts of the baled material will interlock with one and another or" their own accord. However, should it be desired to employ the baling press according to the present invention, for baling some other material, it will be apparent to those skilled in the art that conventional changes may be made in the structure to permit the tying of the bale while under compression.
In Figs. 7, S and 9 is shown an alternative form of. construction for moving the front end of the cover to dovmwardly into compressing relation withthernaterial in the compressing chamber 2. Exceptfor the carrier '73 and its associated strucplates 64 as disclosed in Fig. 5
14, secured the I beam 82 are secured as viewed in Figs. '7 and 8, posite sides, standards 90, each of which has pivoted thereto, about a pin 9|, a swinging arm '92. Each arm 92 has a is connected camming surfaces 87;
The portion of the piston rod Sil'within the carrier 13 has disposed'thereabout the helical spring, which abuts against the collar 19 and the guiding sleeve 80, tends to resiliently maintain the relation between the carrier 73 and end wall 98 chamber 2, since the cover always has a portion thereof Within the chamber 2. However, due to the yielding of the spring I00, the piston rod 55 continues to move to the left, compressing the spring I50, as illustrated in Fig. 8. This movement projects forwardly the I beam 82 and with it the camming surfaces 87 to bring the camming surfaces 8? into contact with the laterally projecting pins 93 of the arms'92. continues to move to the left, the arms 92 are camrnedidownwardly, and as they are cammed downwardly, therollers 91' are forcedinto con Under normal conditions the expansion of:
of the As the piston rod Elltact with bench I02, built up on and extending across the upper surface of the cover 3 to force the cover Gdownwardly into parallel relation with the bottom of the chamber 2. The forward movement of the camming surfaces 81, and thus of the I beam 82 and the piston rod 59 is limited by a collar I03 disposed loosely about the spring I00. The length of the collar I03 is designed so that when it simultaneously abuts against the collar I9 and the guiding sleeve 80, as shown in Fig. 8, the arms 92 will be in vertical or dead center position with respect to the cover 6. As the pins 98 move down the camming surfaces 81, they will move into the hooks 88 so that when in the position disclosed in Fig. 8, with the cover 6 fully depressed, the pins 99 rest within the hooks 88. The purpose of the hooks 8B is to withdraw the arms 92 from dead center position upon initial rearward movement of the piston rod 50 carrying with it the camming surfaces 81. Upon rearward movement of the piston rod 50, after the bale has been formed in the manner hereinabove described, the springs I will expand as the collar 19 moves rearwardly until it abuts against the rear wall of the carrier 13. The action of the collar 19 against the rear wall of the carrier 13 will result in opening the cover 3, the force being transmitted through the carrier 53, the forward bars 62 and the guiding bars I53. When the camming surfaces 81 have withdrawn from contact with the pins 98, the springs 90 will yieldingly urge the tail pieces 93 of the arms 02 against the stops 95 to hold the arms 92 in position for the next closing action of the cover 5.
A feature of the invention which may be employed with e1 her of the forms heretofore disclosed consists of a bale ejector, disclosed in Figs. and 11. For the purpose of illustration, the ejector is shown in association with the baling press disclosed in Figs. 1 through 6. The ejector consists of an L shaped member H0, having a foot portion III, disposed in a recess H2, in the bottom floor of the compressing chamber 2. The member I I0 also has a vertical leg I I3, which when within the baling chamber 2 rests against the end wall 5 of the compressing chamber 2.. The upper end of the leg H3 is secured rigidly to a drum H4, pivoted in the frame I about a shaft H5. On one end of the drum I I4, which projects over one side of the press structure is secured a sheave I I6. The sheave I I6 has secured to its periphery one end of a short piece of flexible cable H! by a suitable securing pin H8. The cable H'I passes part way around the sheave H5 and the other end thereof is fastened to a rod H9 by a a connector I20. The rod I I9 is slidably supported in guides I2I, secured to the side of the press structure.
overhanging the same side of the press structure as that on which the rod I I9 is mounted is a bracket I22, which is secured to the carrier 22. The bracket I22 is provided with an enlarged opening I23 through which the rod H9 extends and has pivoted thereto about a pin I24 a latch I25, which is in the form of a plate, having a slot I26, having a width of substantially the diameter of the rod H9. The latch I25 is provided with an actuating handle I21. For operative relation with the latch I25, the rod H9 is provided with a ball I30 fixed thereto. The ball I30 is of such a size that it will pass through the opening I23 in the bracket I22, but will not pass through the slot I29 in the latch I25.
In operating the ejector according to the present invention the ejector member IIII'ls disposed within the compressing chamber 2 before the material to be baled is loaded therein. It will be understood that the ejector structure is not disclosed in relation to any of Figs. 1 through 9 for the purpose of simplifying those disclosures. As shown in Figs. 10 and 11, the ejecting member II 0 has a width equal to that of the finished bale I3I and a depth as measured by the length of the foot I I I, which is slightly less than the depth of the finished bale I3I. When the compressing chamber 2 is filled with material to be baled, the bale is formed in the manner hereinabove described. The position of the ejecting member I I0 is such that the bale I3 I' is formed thereon. The recess H2, in which the foot portion III of the ejecting member H0 is disposed, is provided to prevent scrap metal being baled from forcing its way beneath the foot member III.
When the bale I3I has been formed on the ejecting member H0, and the platens I and H, shown in Fig. l, withdrawn, the cover 8 is removed from over the compressing chamber 2 by moving the carrier 22 to the right, as viewed in Fig. 10, under the action of the piston rod 50. Previously to this stage of the operation, but following the closing of the cover 6, the handle I21 is swung downwardly, as viewed in Fig. 11, to move the latch I25 to position the slot I28 over the rod I I9. As the carrier 22 moves to the right opening the cover 6, it carries the latch I25 which engages with the ball I30 to draw the rod H9 to the right. The rod H9 draws on the flexible cable III to rotate the drum H4 and in this manner swing the attached ejecting member I I0 together with the bale I3I thereon, to the position shown in dotted outline in Fig. 10. As the foot portion III of the ejecting member H0 swings from the recess H2 within which it is disposed, its outer end follows the curved side I32 of the recess H2. The curved side I32 is provided to reduce the part of the recess H2 not occupied by the foot portion I II to a minimum while at the same time providing clearance to permit the swinging out of the foot portion III. When the ejecting member H0 reaches its uppermost position, the inclination of the leg H3 thereof is sufiicient to permit the bale I3I to slide downwardly therefrom under the action of gravity. The ejecting member H0 may then be returned to its position within the compressing chamber 2, either by moving the carrier to the left to permit the weight of the ejector member H0 to lower itself into the chamber 2, at the same time drawing the rod I I9 through the cable II'I to the left, or by raising the handle I21 to remove the latch I25 from behind the ball I30 to permit the ball I30 to move to the left through the opening I23 in the bracket I22 so that the ejector I I0 may gravitate into the compressing chamber I02 in position for a new cycle of operation.
Another form of the invention is disclosed in Figs. 12 and 13. In this form the swinging arms I39 for forcing the cover 6 downwardly into compressing relation with the material in the compressing chamber 2, after the cover 6 has been moved laterally to closing relation with the chamber 2, are pivoted from the cover 6 carrier I40 rather than from a part of the baling press frame MI. The carrier I40 is similar to the carrier 22 disclosed in Fig. 1 and the cover I3 is suspended therefrom by structure identical with the suspending structure disclosed in Fig. 3. The suspending structure consists of a pair of rods 25 secured to the top of the carriage I40, each rod projecting through the top of the U-shaped bracket 28, having one leg thereof supported from the top of the cover "6 and the other leg thereof supported from 26 and the top of the associated bracket is a spring 21, the springs 21' carrying the weight of the cover 6.
The carriage I is reciprocated by apiston'ro'd I42 corresponding to the piston rod 50 disclosed in Fig. i. The driving connection between the carriage I40 and the cover I3 is the same as the driving connection between the carriage 22 and the cover 6 as disclosed in Figs. 3 and 5, and more particularly consists of a pair of spaced bar members 62 secured to each side of the carriage I40 between each pair of which is vertically disposed a guiding member 63 securedto a plate 64. Each plate 64 is secured to the outside of the lower portion of one of the U-shaped brackets 23.
The carriage I40 is driven from the rod I42 through a spring I43 disposed about the left-end of the rod I42 as viewed in Fig. 12. A collar I44 secured to the rod I42 bearsagainst one end of the spring I43. The other end of the spring I43 bears against an annular plate I45 disposed .on the forward end of the carriage I 40. The outer end of the piston rod I42 is guided in openings I46 in the carriage I40. As the piston rod I42 is moved to the left, the cover 6 is resiliently moved in a closing direction, the force exerted by the piston rod I 42 being transmitted to the spring I43 to the carriage I40, and from the carriage I40 through the bar members 62 to the guiding'members 63. Return movement of the cover 6 is accomplished by reversing the direction of movement of the rod I42 to bring a collar I47 on the rod I42 in engagement with the rear side of the carriage I40.
Each arm I39 is pivoted between ears I48, the ears I48 being provided with vertical slots I49; Pins I50 fixed to the arms I39 extend through the slots I49. Each arm extends through the top of the carriage through a slot I5I between the ears I 38. The arms I39 are rocked about their pins I50 by rollers I52 supported by a bracket I53 secured to the rod I 42, the rollers I52 bearing against a plate I54 bridging the arms I39. The tension of the spring I43 is sufficiently great to permit the closing of the cover 6 until it abuts against the forwardend wall 39 on the chamber 2. ance of the end wall 99, the spring I43 is compressed permitting the bracket I53 to move forwardly under the action of the rollers I 52 into engagement with the bar I54, to pivot the arms I39 about their pivots I53.
As the rod I42 moves forwardly the rollers I52 swing the arms I39 about their pivots I58 until the arms I39 are in a vertical position. The arms I39 are stopped in a vertical position by stops I55 secured to the front wall of the carriage I40 in the path of movement of the respective arms I39. As the arms 539 are swung about their pivots I50, rollers I56 on the upper ends thereof move rearwardly along horizontal stops I 51 secured to parts of the frame I. As the stops I51 are fixed, the lower ends of the arms I39 swing downwardly as well as forwardly, the slots I49 permitting downward movement of the pivots I50. The lower ends of the arms I39 are provided with rollers I 58 which bear against the top of the cover 5.21s the arms I35swingdownwardly and forwardly to cam the cover 6 downwardly, compressing the material in the chamber 2 to be When the cover 6 meets the resistthe rod I42 tomove platens I and II disclosed in Fig. l are actuated in the chamber 2.
Whenthe material in the chamber 2 has been compressed into aha-1e, the rod I42 is moved rearwardly. The initial movement of the rod I42 releases the compression in the spring I43 and at the same time through a bracket E59 extending forwardly from thebracket I53 engages with the forward sides of the arms I39 to swing the arms I33 rearwardly to permit 'thecover 3 to-be elevated by the springs 21. Continued rearward movement on the rod I32 brings the collar '84"! thereon into engagement with the rear wall of the carriage I430 to move the carriage I40 and with it the cover 6 rearwardly to open theichamber 2.
While we have described one .form of the invention where arms are pivoted to the cover 6 carriage, it will be understood that other forms employing aims pivoted to the "carriage may the used. Also, while the foregoing specification has described a press for :baling as such, it will be understood that the invention may be'employed for other forms of compressing and molding'operations, and accordingly, we do not wish to be limited except by the scope of the following claims.
