Abstract: A lawn edger attachment for tractors consisting of a base member adapted to be mounted at the side of a tractor, a boom universally pivoted to the base and angling laterally outwardly from the base, and a generally vertical rolling circular blade mounted beneath the outer end of the boom for rotation both on its own axis and about a generally vertical axis. A single manual operating handle operates to pivot the boom horizontally to position the blade directly above a division line between the grass of a lawn and an adjacent paved area, as the tractor is driven in a direction parallel to the division line, and to pivot the boom vertically, as may be necessary to rest the blade on the ground surface at the division line, and a foot pedal then supplies a mechanically multiplied force to press the blade downwardly to penetrate the ground.

Abstract: A door assembly for installation in a vehicle wall opening which includes a frame and a door hingedly mounted in the frame. The frame is divided into first and second sections. Each section has a flange which abuts the vehicle wall when the sections are connected to mount the door in the vehicle wall opening. Each frame section flange carries a seal which makes sealing contact with the vehicle wall, and the door carries a continuous, peripheral seal which makes sealing contact with the frame when the door is in a closed position to prevent moisture from entering the vehicle.

Abstract: A lawn mower in conjunction with a small tractor, and including a main mower deck disposed forwardly of the tractor and a pair of laterally extending wing mower decks disposed at respectively opposite sides of the tractor, all of the decks carrying mower blades, and a single power source operable to drive all of the blades of all of the decks. The wing decks may each be raised to an inoperative position closely adjacent the sides of the tractor, and in so doing the power drive to the blades of that wing is disconnected, so that the mower may be used with only the main deck in operation if so desired.

Abstract: A storage box for the clippings of a lawnmower consisting of a normally covered box adapted to be mounted on the mower vehicle and to receive grass cuttings and the like of the mower until it is full, and a power mechanism operable when actuated to first raise the box until its pouring lip is higher than the receiving box of a disposal vehicle, such as the bed of a pick-up truck, and transport it horizontally until its pouring lip is over the truck bed, and then to uncover the box and tilt it to pour its contents over its lip into the truck bed.

Abstract: A window assembly used in vehicles including a resilient frame about the peripheral edge of a glazing panel and formed to permit securement of the panel within a window opening without the use of separate attachment devices.

Abstract: A tractor having a frame supported by ground-engaging drive wheels, a tool bar carried by the tractor and on which various implements may be mounted, the tool bar being universally mounted on the frame whereby the implement may be raised above or lowered to the ground, and can follow the contour of the ground, a power unit also mounted on the tool bar so as to have a direct driving connection to the implement not affected by the universal "floating" movement of the implement and tool bar, and a driving connection between the power unit and the drive wheels, of a type not affected by the relative movability of the tool bar and tractor frame, in order that both the implement and the tractor may be driven by a single power unit. Mechanism is also provided for pivoting the tool bar to elevate the implement above the ground when desired, for supporting the tool bar while implements are changed, and for holding the implement firmly against the ground when required.

Abstract: A lawnmower deck of inverted dish shape having three generally circular, laterally spaced but interconnected open-bottomed compartments in each of which is mounted a horizontally extending blade rotatable on a vertical axis and operable to impel cuttings from one compartment to the next toward one side of the deck, the deck having an outlet opening at that side and at the rearward portion of at least certain of the compartments, there being controllable gates at each of the outlet openings and between each successive pair of compartments, to the end that by opening or closing the gates in the proper combinations, the cuttings may be selectively discharged to the side or to a grass collector, or discharged to the rear, or finely mulched for rapid decomposition to enrich the soil.

Abstract: A soil aerating device consisting of a spindle inclined from vertical but power driven to rotate about a vertical axis, and an arm rotatably mounted at its midpoint on the spindle, having a downwardly projecting tubular tine mounted at each end thereof, and being disposed just above ground level, the gyrating movement of the spindle as it rotates about a vertical axis imparting to the arm a movement having a vertical rocking component in a plane longitudinal thereto, so that said tines are alternately inserted into and withdrawn from the ground to form holes therein, and an axial rocking component around the axis of the arm, so that the arm is caused to "walk" rotatively around the vertical axis of rotation.

Abstract: A lawn edger attachment for power driven vehicles consisting of a rolling coulter blade carried for rotation on a horizontal axis transverse to the line of travel of the vehicle at one end of an arm pivoted at its opposite end to the vehicle on a parallel axis. Power means are provided for pivoting the arm. The blade is cup-shaped in order that earth pressure thereagainst will force it to follow the edge of a paved surface. The blade may be reversed so that the vehicle may operate either on the grass or on the pavement. The arm may be extended either forwardly or rearwardly from its pivot, for convenience in various situations. The arm is a horizontal parallelogram linkage, so that the blade can follow the pavement edge even if the vehicle is not steered precisely parallel to this edge.

Abstract: A window assembly which is for mounting in a four-sided vehicle body opening and which includes a rigidifying frame having open ends receiving glass end panels. A glass center panel is carried by the assembly frame and is shiftable over a center opening formed between the two glass end panels.

Abstract: A grass and leaf collector and compactor attachment for lawn mowers consisting of a chute adapted to be mounted at the side of a mower hood to receive mower cuttings ejected from the hood in the lower end thereof, the chute angling upwardly into a hopper also adapted to be mounted on the mower, and a paddle bar extending generally longitudinally through the chute and having paddles secured transversely thereto at intervals along its length. The paddle bar is driven in a vertical orbital path by a special driving connection to a ground-engaging wheel of the mower, so as to impel cuttings received in the lower end of the chute upwardly through the chute into the hopper. The driving connection includes a special safety clutch operable to be disengaged automatically in the event of any substantial obstruction to movement of the paddle bar, so as to prevent damage. The hopper is at a sufficient elevation above ground level that its contents may be dumped by dropping the floor thereof.
