ATTORNEYS CRUSIIER-FEEDER APPARATUS BACKGROUND OF THE INVENTION l. Field of the Invention Compacting or crushing apparatus adapted to feed compressed scrap material rearwardly thereof.

2. Description ofthe Prior Art I-Ieretofore, the jaws of crushers have been pivotally mounted for swinging movement, while the jaws of feed type crushers have been crank operated so as to require additional means for ensuring ovoidal or substantially elliptical movement of said jaws.

SUMMARY OF THE INVENTION This invention relates to novel crusher apparatuses of the feeder type for compacting or compressing entire automobile bodies and frames as well as other scrap material so as to obviate the necessity of precutting the same. Each crusher apparatus has at least one jaw for coacting with a supporting bed or table upon which the scrap material is placed for compaction or compression. Each jaw is adapted to undergo ovoidal or substantially elliptical movement for simultaneously crushing and feeding the material rearwardly of the apparatus, hydraulic cylinders being provided to impart such movement to said jaw. If desired, the crusher apparatus may have a single jaw movable in a vertical or horizontal plane or a pair of coacting jaws movable in substantially contraelliptical paths in a common horizontal or vertical plane, the jaws travelling rearwardly during inward movement thereof.

Preferably each jaw of the crusher apparatus extends at an acute angle to the longitudinal axis of the bed with the rear end of the jaw disposed laterally inward of its front end. Either type of crusher apparatus may be used along or in conjunction with a shear to which the compacted scrap material is fed by the ovoidal movement of the jaw or jaws of the crusher apparatus. Also, an apparatus having a single, vertically movable jaw may be employed in tandem with an apparatus having a pair of horizontally movable jaws so as to positively compact the material in both directions. If desired, the bed of either crusher apparatus, particularly the single jaw type, may be slidably mounted for longitudinal movement with the jaw.

Constructions designed to carry out the invention will be described hereinafter, together with other features thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, the numeral 1 designates a shear of the hydraulic type having a transverse, vertically movable blade 2 (FIG. 3) at its front end. Collinear horizontal and vertical crusher-

feeder apparatuses

3 and 4, embodying the principles of the invention, may be mounted in tandem ahead of the shear 1 with the horizontal crusher-feeder apparatus 3 being positioned intermediately thereof or adjacent said shear. As will be apparent, the crusher-feeder apparatuses are adapted to coact for crushing and feeding scrap material. such as paper, automobile bodies and frames, to the shear. It is noted, however, that either apparatus, particularly the horizontal apparatus, is capable of independent use and may or may not be used with a shear which may be of any suitable type.

As best shown in FIGS. 2-4, the horizontal crusher-feeder apparatus 3 includes an open, rectangular frame 5, preferably, formed of channels and having corner and longitudinal side posts or upright end and lateral members 6 and 7 (FIGS. 2 and 4) connected at their lower ends by opposed pairs of longitudinal and transverse, horizontal beams or

crossmembers

8 and 9. One of the longitudinal bottom beams 8 is secured to the inner surfaces of each group or set of the corner and

side posts

6 and 7 and the inner surfaces of said beams 8 have theends of the transverse bottom beams 9 attached thereto in alignment with said posts.

Somewhat similar pairs of longitudinal and transverse, horizontal beams or

crossmembers

10 and 11 are spaced above the

marginal beams

8 and 9 for connecting and reinforcing the intermediate portions of the corner and side posts at the margins of the frame 5, while the medial portions of the marginal transverse beams 11 are connected and reinforced by a longitudinal, horizontal, center beam or crossmember 12 (FIG. 3) which is parallel and similar to the marginal longitudinal beams 10. The front intermediate portion of the center beam 12 as well as the front intermediate portions of the longitudinal marginal beams 10 are braced by a pair of short,

transverse beams or crossmembers l3 aligned with the front side posts 7.

A similar short, longitudinal beam or crossmember 14 extends between each short, transverse beam 13 and the rear marginal beam 11 in adjacent, parallel relation to each marginal beam 10. The medial portion of each short, longitudinal beam 14 and the rear intermediate portion of the center beam are connected and reinforced by short, transverse beams or crossmembers 15 in alignment with the rear side posts, while similar shorter beams or crossmembers 16 extend between the

beams

10 and 14 collinearly with the beams 15. As shown by the numeral 17, an upright supporting member or short post extends between each end of the center beam 12 and the underlying medial portion of each marginal bottom beam 9. Similar supporting members or posts 18 connect the medial portions of the longitudinal beams 14 and the underlying portions of the intermediate, transverse bottom beams 9.

A hexagonal bed or table 19, in the form of relatively thick, trapezoidallike baseplate, overlies and is supported by the beams 10-l6 and has its wide portion coextensive with the front portion of the frame 5, whereby the, front transverse margins 20 of the bed or baseplate 19 is aligned with the external margin of the front transverse beam 11 and the parallel end margins 21 of the wide portion of said bed or plate are aligned with the external margins of the longitudinal beams 10. Rearwardly of the parallel end margins 21, the lateral margins 22 of the bed 19 converge toward a relatively short, rear transverse marginal portion 23 which overlies the external margin of the rear transverse beam 11. As best shown in FIG. 3, the marginal portion 23 is of elongate, rectangular shape and projects rearwardly beyond the rear marginal beam 11 for abutting engagement with an extension 24 of the bed (not shown) ofthe shear 1.

Transverse marginal beams or crossmembers 25, similar to the

marginal beams

9 and 11, extend between and connect the upper ends of the corner posts 6 and have a plurality, preferably three, of equally-spaced longitudinal beams 26 extending between the end and medial portions thereof (FIG. 8) in overlying coplanar relation to the beams 12 and 14 (FIG. 2). The intermediate portions of the longitudinal beams 26 are reinforced by two sets of collinear, transverse,

short beams

27 and 28 which are aligned with the upper ends of the side posts 7 so as to be in overlying coplanar relation to the beams 13 and

collinear beams

15 and 16. A hexagonal, trapezoidallike top plate 29, substantially identical to and aligned with the bed or bottom plate 19, is secured to the beams 2528 in underlying relationship (FIG. 8). The plate 29 lacks the rectangular rearward projection 23 of the bed 19 since it is unnecessary.

A pair of upright jaws or rams 30 is pivotally mounted between the

plates

19 and 29 for longitudinal, contraelliptical movement in a horizontal plane. The jaws 30 converge rearwardly of the frame and are adapted to travel inwardly and rearwardly toward each other for imparting concurrent movement to, as well as for simultaneously crushing, scrap metal or other material placed between said jaws. Each jaw may include an upright, flat, rectangular member or backplate 31 of relatively thick metal and of greater horizontal length than height. For providing a coextensive row of rearwardlydirected serrations or toothlike projections 32, a plurality of rectangular faceplates or flat elements 33, of relatively thick metal, is secured to the inner surface of each backplate 31 in overlapping relationship with the rear vertical margin of each faceplate overlying the front vertical margin of the adjacent faceplate. A coextensive parallel reinforcing member or bar 34 is secured to the outer surface of each backplate in spaced contiguity to each longitudinal margin thereof for connecting each jaw 30 to an ovoidal movement imparting mechanism.

Preferably, this mechanism includes a trio of double-acting

hydraulic cylinders

35, 45 and 55 having pivotal connecting elements or

connectors

36, 46 and 56, respectively, extending axially from their outer ends and provided at their respective inner ends with upright gudgeon or

trunnion pins

37, 47 and 57. Coaxially-opposed

bearings

38, 48 and 58 are mounted above the longitudinal beams and 14 and below the

beams

28, 26 and (FIG. 2) to permit horizontal swiveling or swinging ofthe

cylinders

35, 45 and 55 relative to the frame 5. The bearings 38 are disposed adjacent the front side posts 7, the bearings 48 are in proximity to the short, transverse beams 13 and the bearings 58 are at the junctures of the

marginal beams

10 and 11 as well as the ends of the transverse marginal beams 25, whereby the

cylinders

35 and 55 extend forwardly at acute angles and the cylinders 45 are positioned at acute rearward angles to the retracted jaws 30. Although the

connectors

36 and 46 are in the form of apertured ears or lugs, each connection 56 is elongated or in the form of a flat bar whereby the cylinder 55 is spaced an appreciable distance from its trunnion pin 57.

Piston rods

39, 49 and 59 project from the inner ends of the respective cylinders and have pivotal connecting elements or connectors 40, 50 and 60 at their respective outer ends for rotatable mounting on upright wrist pins 41 and 51. As shown in FIG. 4, the pins 51 are common to the connectors 50 as well as the connectors 60, which are in the form of clevises, and have their ends journaled in the rear ends of the longitudinal reinforcing bars 34 of the jaws, while the ends of the pins 41 are journaled in said bars in spaced relation to the front ends thereof. Although not illustrated, the cylinders are provided with the usual hydraulic connections for reciprocating their respective piston rods and oscillating said cylinders between the full and broken lines positions of FIG. 3. Due to this arrangement, the jaws are moved in contraelliptical paths for crushing and feeding to the shear 1 scrap metal or other material placed on thebed 19.

As most clearly shown in FIGS. 5-7, the vertical crusherfeeder apparatus 4 includes an open, rectangular frame 44, formed of channels, which is similar to the frame 5 of the assembly 3 and which has a plurality of lateral, upright supporting members or corner or end and side posts 61-64. For closing the lateral sides of the frame 44, an upright relative thick plate 65 overlies and is secured to the inner surfaces of each lateral group or set of the posts 61-64. A longitudinal, horizontal, bottom beam 66, similar to the beams 8, is secured to the inner face of each sideplate 65 and is connected by a plurality of horizontal transverse, bottom beams 67, similar to the beams 9 and aligned with the lower ends of said posts, to

the opposed identical beam that connects the other group or set of posts. Above and aligned with the

beams

66 and 67, similar longitudinal and transverse, horizontal,

intermediate beams

68 and 69 are disposed between the sideplates for supporting a rectangular bed or table 70 that is coplanar and identical to the bed 19 except for its shape. As shown by the

numerals

76 and 77, the rear margins of the sideplates 65 and bed 70 may project beyond the rear corner or end posts for engagement with the frame of the horizontal crusher-feeder assembly.

The height of the front corner or end posts 61 is greater than the rear side posts 63 and less than the other posts, while the front side posts 62 are of greater height than the rear corner or end posts 64. A plurality of horizontal, transverse,

top beams

71, 72 and 74, similar to the beams 25, extends between and connects the upper ends of each of the pairs 144 159

posts

61, 62 and 64. As best shown in FIG. 6, the upper portions of the

posts

62 and 64 of each lateral group or set are connected by a horizontal, longitudinal, top beam or crossmember 73 which overlies and is secured to the upper end of the post 63 between said posts. A horizontal, transverse, top beam or cross member 75, similar and parallel to the

beams

71, 72 and 74, overlies and connects the front end portions of the longitudinal top beams 73 adjacent said beam 72.

The vertical crusher-feeder apparatus 4 is provided with a horizontal, jaw or ram that may be similar to the jaws 30 and have a similar backplate 81, a similar row of serrations or toothlike projections 82, similar overlapping faceplates 83 and similar parallel reinforcing bars 84. As best shown in FIG. 5, the backplate 81 of the jaw 80 is substantially square and has its lateral margins adjacent the upright sideplates 65. The jaw is inclined downwardly and rearwardly of the frame 44 and is adapted to travel downwardly and rearwardly for imparting concurrent movement to scrap metal placed upon the bed 70 during crushing thereof.

For imparting longitudinal ovoidal movement in a vertical plane, a trio of double-acting

hydraulic cylinders

85, 95 and 105 are provided and have pivotal connecting elements or connectors 86, 96 and 106 extending axially from their respective outer or upper ends. The connectors 86 and 96 are in the form of apertured ears or lugs so as to be similar to the connecting

lugs

36 and 46, while the connector 106 is similar to the connectors 56 and is elongated or in the form of a flat bar. As indicated at 87, 97 and 107 in FIG. 6, the connectors are pivotally attached to the undersides of the

top beams

72, 75 and 74 in the same manner as the

connectors

36, 46 and 56 so as to suspend the

cylinders

85, 95 and 105 for swiveling or swinging movement medially of said beams.

Piston rods

88, 98 and 108, similar to the

rods

39, 49 and 59, project from the inner or lower ends of the respective cylinders and have means 89, 99 and 109, similar to the connecting elements or connectors 40, 50 and 60 and the wrist pins 41 and 51, at their respective outer or lower ends for pivotal attachment to the jaw 80. As shown in FIGS. 5 and 6, the pivotal attachment means 89 has connection between and with the reinforcing bars 84 in spaced relation to the front ends thereof and the attachment means 99 and 109 has common connection between and with the rear ends of said bars. Due to this arrangement, the cylinders and 105 extend forwardly and the cylinder extends rearwardly at acute angles to the retracted jaw. The operation of the jaw 80 is identical to that of either one of the jaws 30 and hydraulic connections (not shown) are provided for actuating the cylinders to reciprocate this

piston rods

88, 98 and 108 and oscillate said cylinders between the full and broken line positions of FIG. 6.

Due to the hydraulic cylinders forming the sole connection of each of the

jaws

30 and 80 to the frame, it is readily apparent that each jaw follows the path of least resistance and that its angular relationship varies in accordance with the resistance encountered. For example, there may be less resistance to inward or downward movement of the outer end portion of the jaw whereby said jaw portion moves inwardly or downwardly relative to the inner end portion of said jaw. ln

the event that the resistance is equal, the angular relationship of each jaw may remain constant.

The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
