Abstract
Abstract A cabinet for a trash compactor having a vertically arranged open top, disposable container for receiving trash and a vertically downwardly movable ram for compressing the trash in the container, including a floor pan for supporting the container and a horizontal frame above the floor pan for supporting the ram and a means for moving the ram, with the side edges of the floor pan and frame interconnected by vertical, sheet metal side cabinet panels, each having its forward and rear edges bent into vertical tubular shapes which form the four vertical corners of the cabinet. The tubular shapes function as columns to support the frame and ram, and the panels function to receive in tension and to absorb the reaction load of the ram upon the frame and the compressive load upon the pan, which loads are transmitted to the panels by the frame and pan.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
290 words
A cabinet for a trash compactor of the type having a vertically arranged, open top container for receiving trash and within which trash is downwardly compressed by a vertical ram member having means mounting the ram member above the container for vertical movement into and out of the container, said cabinet comprising: a horizontal floor pan upon which the bottom of the container is supported, the pan having opposite side edges; a horizontal frame spaced a distance above and having side edges vertically aligned with the pan side edges, the frame being formed to dependingly support the ram member mounting means; a pair of vertically elongated, rectangular, relatively thin sheet metal side panels, each vertically extending between a pan side edge and its corresponding frame side edge, the panels extending the full length of said side edges, with the upper and lower edges of each of the panels being arranged in face to face contact with and mechanically secured to their adjacent pan and frame side edges; the vertical edges of each of the panels being bent into integral, continuous, vertically extending tubular shapes, each offset outwardly of the frame and pan, with the tubular shapes each forming one of the four vertical corners of the cabinet; wherein the tubular shapes form vertical columns to rigidly support the frame and wherein the reaction forces applied to the frame by the downwardly moving ram member and the compressive forces applied to the pan during compression of the trash in the container are transferred through the side edges of the frame and pan to the sheet metal body of each of the panels, placing these under tension so that said side panels thereby receive and absorb said reaction and said compressive loads.
Claim 2
Dependent Claim
290 words
A cabinet for a trash compactor of the type having a vertically arranged, open top container for receiving trash and within which trash is downwardly compressed by a vertical ram member having means mounting the ram member above the container for vertical movement into and out of the container, said cabinet comprising: a horizontal floor pan upon which the bottom of the container is supported, the pan having opposite side edges; a horizontal frame spaced a distance above and having side edges vertically aligned with the pan side edges, the frame being formed to dependingly support the ram member mounting means; a pair of vertically elongated, rectangular, relatively thin sheet metal side panels, each vertically extending between a pan side edge and its corresponding frame side edge, the panels extending the full length of said side edges, with the upper and lower edges of each of the panels being arranged in face to face contact with and mechanically secured to their adjacent pan and frame side edges; the vertical edges of each of the panels being bent into integral, continuous, vertically extending tubular shapes, each offset outwardly of the frame and pan, with the tubular shapes each forming one of the four vertical corners of the cabinet; wherein the tubular shapes form vertical columns to rigidly support the frame and wherein the reaction forces applied to the frame by the downwardly moving ram member and the compressive forces applied to the pan during compression of the trash in the container are transferred through the side edges of the frame and pan to the sheet metal body of each of the panels, placing these under tension so that said side panels thereby receive and absorb said reaction and said compressive loads.
Claim 3
Dependent Claim
67 words
A cabinet as defined in claim 1, and wherein the upper and lower edges of the side panels are bent into integral horizontal flanges, with the upper flanges overlapping and arranged in face to face contact with the upper surface of their adjacent frame side edges, and the lower frames are arranged in face to face contact with the lower surfaces of their adjacent pan side edges.
Claim 4
Dependent Claim
58 words
A cabinet as defined in claim 1, and said frame comprising opposite, elongated side members and cross-members spanning between and having their opposite ends connected to the side members, with the cross members being located a distance from the opposite ends of the side members for extending directly over and for connection to the ram member mounting means.
Claim 5
Dependent Claim
60 words
A cabinet as defined in claim 3, and said pan comprising a flat, rectangular sheet, having downwardly bent integral edge flanges which form its side edges, and having reinforcing channels secured to the undersurface of the sheet and extending from side edge to side edge and located directly beneath the area of the sheet upon which the container is supported.
Claim 6
Dependent Claim
37 words
A cabinet as defined in claim 4, and includIng roller-type supports secured to the pan for supporting the cabinet for rolling movement upon a floor surface and for supporting the pan a distance above the floor surface.
Claim 7
Dependent Claim
71 words
A cabinet as defined in claim 1, and with one of the tubular shapes formed on corresponding vertical edges of each of the panels being formed by bending its panel vertical edge normal to the panel body, then parallel to and overlapping the panel body, then normal towards the panel body again to form a generally square cross-section, each tubular shape extending sideways outwardly of the plane of its respective panel.
Claim 8
Dependent Claim
131 words
A cabinet as defined in claim 1, and with one of the tubular shapes formed on corresponding vertical edges of the panels being formed by bending the panel edge perpendicular to the panel body towards the opposite panel, then parallel to the panel body, then perpendicular to and extending back towards its respective panel body, but with free edges spaced a short distance from its respective panel body to form a continuous vertically extending slit into the roughly square cross-section tubular shape frame thereby; and a vertical cover plate extending between said corresponding vertical edges, with the opposite edges of the cover panel bent into flanges which are inserted into their adjacent slits and mechanical fastening means securing the opposite edge portions of the cover panel to their adjacent tubular shapes.
Claim 9
Dependent Claim
162 words
A cabinet as defined in claim 1, the cabinet having a forward face and a rear face, with the tubular shapes formed on the rear edges of the side panels each being formed by bending its panel rear vertical edge perpendicularly outwardly of the body of the panel, then parallel to and forwardly of the panel body and then perpendicular to and towards the panel body to form a roughly square cross-sectional shape arranged on the outer surface of and extending sidewise of the body of the panel; and with the tubular shapes formed on each of the panel forward vertical edges being formed by bending the panel edge perpendicular of the body panel towards the opposite panel, then parallel to and rearwardly of the panel body, then perpendicular to and towards the panel body to provide a roughly square cross-section on the inner surface of the body of the panel, and forwardly of the forward edges of the frame and pan.
Claim 10
Dependent Claim
85 words
A cabinet as defined in claim 8, and with the free edges of the sheet metal bent into forward tubular shapes being spaced a short distance from their adjacent body portions to form a continuous vertical slit; and a forward, vertically arranged cover panel extending between the forward vertical shapes and having its vertical edges bent into forwardly directed flanges, inserted into their adjacent slits, with the vertical side edge portions of the cover panel fastened by mechanical fasteners to their adjacent tubular shape surfaces.
