The chamber 2 is provided 22. 10 with an open top closable by a cover 6. For the Secured to the top of the carrier 22 are two sake of simplicity of illustration, the side mem pairs of ears 34, and secured directly beneath the bers 3 and the cover 6 have been shown as thick 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 solid members. However, it will be understood that these parts of the construction may be con structed of structural members and sheets or otherwise, if desired. The end of the chamber 2 opposite the end wall 5 is constituted by a platen '|, movable under the action of a piston rod 8 actuated by a piston 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 9 in a hydraulic cylinder Hi. In one of the side 20 pivoted. 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. 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 2. It will be understood that the platen | I moves rod 50, actuated by a piston 5|, in a hydraulic at right angles to the direction of movement of 25 cylinder 52. The piston rod 50 extends through an opening the platen 1.

In all positions of the cover Fig. 1 and in Fig. 6, and the forward end of the 6, its rear portion is supported by the wheels 26 cover 6 is relatively above the rear end, as shown in such a manner that it is disposed between the in dotted outline in Fig. 1 for all cover positions side wall extensions 2| and guided thereby. Fur except in ?nal baling position. It will be under thermore, 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 par ticularly 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 stood 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, se cured to the plates 24, and tied together with a disposed helical springs 21, resting on the stops bar 58. Connected to the standards 51 are verti 26. Projecting upwardly from the top of the cal stops 59 for limiting the leftward movement cover 6 are a pair of U shaped brackets 28, hav 70 of the carriage 22 under the action of the piston ing openings 29 in the top thereof, through which rod 50, as shown in Fig. 1.

Since the carrier 22 is At each end of camming members the I beam 82 are secured 35 as viewed in Figs. '7 and 8, posite sides, standards 90, each of which has pivoted thereto, about a pin 9|, a swinging arm 40 '92. Each arm 92 has a ' ' is connected center positions. The 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 in clined as it was when the toggles were collapsed, but will be parallel to the bottom e of the com camming surfaces 87; The portion of the piston rod Sil'within the car~ rier 13 has disposed'thereabout ' ‘ pressing chamber 2. The cover is held in this Under normal‘ conditions the expansion of: position while the platen ‘i is moved to the left the helical spring,‘ which abuts against the collar into alignment with the nearest edge of the plat 19 and the guiding sleeve 80, tends to resiliently en H, and then the platen H is moved laterally 55 maintain the relation between the carrier 73 and across the compressing chamber 2 to complete the formation of the bale. Since the baling press,,according to the present invention, is de signed for baling sheet metal scrap, it is not nec essary to provide any arrangement for tying the compressed material together as the parts of the baled material will interlock with one and an other 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. end wall 98 of the 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 move ment projects forwardly the I beam 82 and with it the camming. surfaces 87 to bring the camming surfaces 8? into contact with the laterally project ing pins 93 of the arms'92. As the piston rod Ell continues to move to the left, the arms 92 are Exceptfor the carrier '73 and its associated struc~ 75 camrnedidownwardly, and as they are cammed ‘ downwardly, therollers ‘91' are forced’intov cone 2,413,054 tact 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 move ment 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 col lar ‘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 within the compressing chamber 2 before the material to be baled is loaded therein. It will be understood that the ejector structure is not dis closed 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 ?nished 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 ?nished bale I3I. When the compressing chamber 2 is ?lled with material to be baled, the bale is formed in the manner hereinabove de scribed. 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 6 fully depressed, the pins 99 rest within the way beneath the foot member III. 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. When the bale I3I has been formed on the ejecting member H0, and the platens ‘I and H, 20 shown in Fig. l, withdrawn, the cover 8 is re moved 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. hereinabove described, the springs I00 will expand as the collar 19 moves rearwardly until it abuts 25 Previously to this stage of the operation, but fol lowing the closing of the cover 6, the handle I21 against the rear wall of the carrier 13.

As the foot portion A feature of the invention which may be em III of the ejecting member H0 swings from the ployed with e1 her of the forms heretofore dis recess H2 within which it is disposed, its outer closed consists of a bale ejector, disclosed in Figs. Upon rearward movement of the piston rod 50, after the bale has been formed in the manner r end follows the curved side I32 of the recess H2. 10 and 11. For the purpose of illustration, the ejector is shown in association with the baling 40 The curved side I32 is provided to reduce the part of the recess H2 not occupied by the foot press disclosed in Figs. 1 through 6. The ejector portion I II to a minimum while at the same time consists of an L shaped member H0, having a providing clearance to permit the swinging out foot portion III, disposed in a recess H2, in the of the foot portion III. When the ejecting bottom floor of the compressing chamber 2. The member H0 reaches its uppermost position, the member I I0 also has a vertical leg I I3, which when inclination of the leg H3 thereof is su?icient within the baling chamber 2 rests against the to permit the bale I3I to slide downwardly end wall 5 of the compressing chamber 2.. ‘ The therefrom under the action of gravity. The upper end of the leg H3 is secured rigidly to a ejecting member H0 may then be returned to drum H4, pivoted in the frame I about a shaft its position within the compressing chamber H5. On one end of the drum I I4, which projects 2, either by moving the carrier to the left to per over one side of the press structure is secured a mit the weight of the ejector member H0 to sheave I I6. The sheave I I6 has secured to its pe lower itself into the chamber 2, at the same time riphery one end of a short piece of ?exible cable drawing the rod I I9 through the cable II'I to the H‘! by a suitable securing pin H8. The cable left, or by raising the handle I21 to remove the H'I passes part way around the sheave H5 and latch I25 from behind the ball I30 to permit the the other end thereof is fastened to a rod H9 by a ball I30 to move to the left through the opening a connector I20. The rod I I9 is slidably support I23 in the bracket I22 so that the ejector I I0 may ed in guides I2I, secured to the side of the press structure. overhanging the same side of the press struc ture 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 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 car rier 22 disclosed in Fig. 1 and the cover I3 is sus 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 pro vided with an actuating handle I21. For opera tive relation with the latch I25, the rod H9 is 70 pended therefrom by structure identical with the provided with a ball I30 ?xed thereto. The ball suspending structure disclosed in Fig. 3. The sus I30 is of such a size that it will pass through the pending structure consists of a pair of rods 25 opening I23 in the bracket I22, but will not secured to the top of the carriage I40, each rod pass through the slot I29 in the latch I25. In operating the ejector according to the pres 75 projecting through the top of the U-shaped ent invention the ejector member IIII'ls disposed 2,413,054 bracket 28, having one leg thereof supported from the ‘top of the cover "6 and the other ‘leg thereof supported from ' platens ‘I and II disclosed in Fig. l are actuated in the chamber 2. spring 21, the springs 21' carrying the weight of When‘the material in the chamber 2 has been the cover 6. compressed into aha-1e, the rod I42 is moved rear wardly. The initial movement of the rod I42 re The carriage I40 is reciprocated by apiston'ro'd I42 corresponding to the ‘piston rod ‘50 disclosed 10 leases the compression in the spring I43 and at the same time through a bracket E59 extend in Fig. i. The driving connection between the 26 and the top of the associated bracket 25 is a carriage I40 and the cover I3 ‘is the same ‘as the ing forwardly from the‘bracket I53 engages with driving connection between the carriage .22 and the forward sides of the arms I39 ‘to swing the arms I33 rearwardly to permit 'thecover 3 to-be the cover 6 as disclosed in Figs. 3 and 5, and more particularly consists of a pair of spaced bar mem bers 62 secured to each side ‘of the carriage I40 between each pair of which is vertically disposed a guiding member 63 secured‘to 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 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 theicham ber 2. through a spring I43 disposed about the left-end While we have described one .form of the ‘in vention where arms are pivoted to the cover 6 of ‘the rod I42 as viewed in Fig. 12. A collar I44 secured to the rod I42 bearsagainst one end of carriage, it will be understood ‘that other forms employing aims pivoted to the "carriage may the 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'mem bers 63. Return movement of the cover 6 is ac complished by reversing the direction of move used. Also, while the foregoing speci?cation 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'op erations, and accordingly, we do not wish to be limited except by the scope of the following claims.
