DESCRIPTION OF THE PREFERRED EMBODIMENT In the exemplary embodiment of the invention as disclosed in the drawing, a refuse compactor generally designated 10 is shown to include an outer cabinet I l. Refuse depositedin a drawer 12 of the compactor is compacted by means of a ram 13 which is disposed in the upper portion of the cabinet in an upper, retracted position and which is selectively driven downwardly into the drawer by a power drive including a pair of upright threaded shafts 14 and 15. As shown in FIG. 3, the shafts extend downwardly through a base wall 16 extending across the bottom of cabinet 11 with the lower ends of the shafts being journalled in suitable bearing supports 17 and each carrying a driven sprocket 18 below base wall 16. Rotation of the shafts about the vertical axis thereof imparts a selective downward and upward movement to the ram, depending on the direction of rotation of the shafts, in a manner similar to that disclosed in the above identified Hinkel et a]. US. Pat. No. 3,537,390, which patent is incorporated by reference herein as a disclosure of such ram operating means.
As indicated briefly above, the present invention comprehends providing an improved means for effecting the driving rotation of shafts 14 and 15. More specifically, the present invention comprehends providing a mounting member 19 in the form of a plate having a central opening 20. The electric drive motor 21 is mounted on a depressed central portion 22 of the mounting plate by means of suitable resilient grommets 23 and securing nuts 24 threaded to depending screws 25 on the motor 21. The motor drive shaft 26 extends downwardly through mounting plate opening and carries at its lower end a drive gear 27 which is disposed below the mounting plate (as shown in FIG. 4) for meshed engagement with a driven gear 28 rotatably joumalled on a stub shaft 29 depending from the mounting plate 19. Gear 28 includes a hub 30 and a driver sprocket 31 for driving a chain 32 trained around the ram drive shaft sprockets 18, as shown in FIG. 3. The location of the motor screw holes 33 relative to the stub shaft 29 may be accurately preselected for accuracy in the disposition of driver gear 27 on motor shaft 26 and driven gear 28 on stub shaft 29. The integral driven gear 28, hub 30, and driver sprocket 31 may be rotatably retained on stub shaft 29 by a suitable retaining ring 34, as shown in FIG. 4.
Mounting plate 19 includes a pair of flat edge portions 35 and 36, each of which is provided with a pair of aligned slots 37 for use in adjustably positioning the mounting plate 19 on the base wall 16. Referring more specifically to FIG. 5, the base wall is provided with an opening 38 slightly smaller than the periphery of the mounting plate 19 for facilitated extension of the motor 21 therethrough. The base wall is further provided with a plurality of square openings 39 adjacent the edge of opening 38 disposed in conformity with the arrangement of the slots 37 in mounting plate 19. Screws 40 having a square shoulder are arranged with the threaded shank portion 41 thereof extending one each through the respective four holes 39 and with the head portion 42 thereof engaging the base wall 16 and the square shoulders engaging square holes 39. The screws are retained in association with the base wall by means of spring clips 43 each having an upper leg portion 44 having a bifurcated end 45 straddling the screw shank 41, and an opposite concave leg 46 abutting the screw head 42. The spring clip effectively defines a U- member extending about the edge of the base wall defining opening 38 and may be installed in association therewith by simple lateral movement thereof over the edge of opening 38 subsequent to the insertion of the screw 40 through the opening 39. The mounting plate 19 is secured to the base wall 16 by passing of the screw shanks 41 upwardly through the slots 37 permitting the mounting plate to be fixedly retained in association with the base wall by means of a suitable nut 47 and friction washer 48. Alternately, nut 47 and friction washer 48 may be replaced by a self-locking nut of the type generally available. The elongated slots 37 permit an adjustable positioning of the mounting plate 19 on the base wall so that chain 32 may be readily installed and the tension thereof adjusted by suitable positioning of the mounting plate over the screws 40. The drive may be then readily secured in the adjusted position by the suitable tightening of nuts 47 against the mounting plate edge portions 35 and 36 to complete the installation of the ram drive means.
As shown in FIG. 4, the base wall 16 of cabinet 1 1 defines a downtumed edge 49. An upstanding frame structure 50 is carried on the base wall 16 to receive thereacross the cabinet 11 where the refuse compactor is a free-standing refuse compactor, as shown in FIG. 1. Where the compactor is an under-the-counter compactor, the outer cabinet 1 1 may be omitted. The frame 50 is secured to flange 49 by suitable means, such as welding 51. Downtumed edge 49 defines a drive space 52 in which the drive gear 27, driven gear 28, sprockets 18, 31, and 32 are disposed above the lowermost distal edge 53 of the cabinet sidewall at the bottom of flange 49. As further shown in FIG. 4, levellers 54 may be threaded to the base wall for permitting levelling of the cabinet 11 as desired. As shown in FIG. 2, base wall 16 carries, in the space 55 thereabove, suitable roller guide means 56 for movably carrying the drawer l2 forwardly of the motor 21 with the forward end of the space 55 being closed by an upright wall 57 rearwardly of the drawer 12 in the retracted, or compacting, position thereof within cabinet 11. Thus the mounting plate 19 effectively carries the drive motor 21 in space 55 superjacent the base wall 16 and the drive gear, sprockets, and chain in space 52 subjacent the base wall for facilitated installation and maintenance.
As the drive motor and drive gears are mounted as a unit on the mounting plate, installation of the drive means is facilitated. Thus, the frame 50 may be inverted so as to dispose the base wall 16 uppermost permitting the drive assembly to be installed thereon by mounting the threaded shafts 14, 15 together with bearing supports 17 and sprockets 18, then by movement of the drive motor secured to the mounting plate downwardly through the opening 38 in the base wall with the mounting plate being secured to the base wall by means of the screws 40 and nuts 47, as illustrated in FIG. 5. Screws 40 are retained in upstanding relationship to the base wall 16 at this time by the clips 43. The chain 32 is then installed around sprockets l8 and 31 and the mounting plate 19 positionably adjusted by virtue of the movement permitted by slots 37 relative to screw shanks 41 to provide the desired tension in chain 32. The nuts 47 may then be tightened to fixedly secure the drive assembly in the compactor in the adjusted position. The frame 50, with the drive now fully installed therein, may be then returned to the upright position for completion of assembly and for installation of the cabinet 11 thereon, if desired, as discussed above.
Servicing of the drive means is facilitated by virtue of the fully accessible arrangement of the drive means, as best seen in FIG. 3. Thus, in servicing the drive, the user need merely invert the compactor so as to once again place the drive means in the uppermost position for free accessibility to all portions thereof as desired.
By virtue of maintaining the fixed centers of the gears 27 and 28, improved accuracy in the power transmission to the sprocket and chain drive is maintained.
As the clips 43 may be retained in place on the base wall with the legs 44 disposed between the base wall and the mounting plate portions 35 and 36, removal of the nuts 47, such as in removing the motor drive portion of the structure, does not affect the retention of the screws on the base wall notwithstanding the inverted disposition of the frame during such servicing. Further, by utilization of the gear power take-off means, a speed reduction to the chain sprocket 31, such as a reduction of 6-to-l, is readily obtained with minimum cost. The entire power drive between the motor shaft 26 and ram drive shafts l4 and may have effectively minimum vertical dimension for simplified installation in the compactor while yet providing accurate laterally spaced relationships between the elements of the drive for facilitated accessibility as discussed above.
The foregoing disclosure of specific embodiments is illustrative of the broad inventive concepts comprehended by the invention.
