Patent number: 4796322Abstract: A rear dumping brush-type lawn sweeper for attachment to a garden tractor includes a hamper assembly which is mounted on a support frame for pivotal movement. The support frame is carried on the main frame of the brush housing. The hamper assembly carries an open top hamper bag. The top of the bag is normally closed by a mesh-type folding wind apron. A forward portion of the apron is attached to the hamper assembly, while a rear portion of the apron is attached to a rear cross member forming part of the hamper support frame. The wind apron, at its rear terminal end, forms a closure with the rear lip of the hamper bag in the normal running position. When the hamper is rotated rearwardly on the support frame for dumping, the wind screen folds on itself and exposes a rear dumping opening with the rear hamper bag lip.Type: GrantFiled: April 4, 1988Date of Patent: January 10, 1989Assignee: Lambert CorporationInventors: Jeffrey A. Steed, Walter F. Ruhl, James M. Weaver

Patent number: 4718222Abstract: A universal mower deck discharge boot is formed by rotational molding into two sections which telescope one over the other and each of which is formed with a blank forwardly or side facing wall portion, which wall portions together are adapted to be cut out and formed with an opening which closely conforms to the discharge chute of a mower deck. The forward section is otherwise generally closed at the sides and the top and the bottom and is formed with a curved forward wall to resist catching on obstructions, while the rear section is formed with a discharge spout adapted to receive a flexible conduit. The sections telescope one relative to the other to conform to the dimensions of a wide variety of mower deck discharge chutes.Type: GrantFiled: July 25, 1983Date of Patent: January 12, 1988Assignee: Lambert CorporationInventors: Stephen K. Lambert, Dean A. Bliskey

Patent number: 4275651Abstract: A cabinet has an upper portion which encloses a ram member movable vertically by a motor driven scissor-type actuator from an upper retracted position to a lower extended compacting position within a container positioned within the lower portion of the cabinet. The container is molded of a plastics material and is supported by a two-wheeled cart including pivotal arms which extend around an intermediate portion of the container and are locked together for restraining the container during compacting. When the container is tilted by the cart into a compacting position under the ram member, the container actuates a sealing frame which lowers and engages the upper rim of the container for confining within the upper portion of the cabinet any odors released by the material being compacted within the container.Type: GrantFiled: May 15, 1980Date of Patent: June 30, 1981Assignee: Lambert CorporationInventors: Hugh F. Groth, Guilbert M. Hunt, Ronald E. Shaner

Patent number: 4261593Abstract: A relatively compact and lightweight planting and fertilizing apparatus is attached to a small garden tractor by a universal hitch which restricts lateral movement between the two. The apparatus is spring biased downwardly to assure film contact with the ground, and can be raised above the ground by a single lever. The lever carries the biasing spring, and cams lifting bearings on the lever against a lifting plate on the apparatus. The fertilizer is fed by an axially adjustable feed gear rotated by a ground engaging wheel on the apparatus. The feed gear is biased by an adjusting spring against a threaded adjusting knob which sets the axial position of the feed gear.Type: GrantFiled: December 20, 1979Date of Patent: April 14, 1981Assignee: Lambert CorporationInventor: Robert R. Yeager

Patent number: 4239086Abstract: A relatively compact and lightweight planting and fertilizing apparatus is attached to a small garden tractor by a universal hitch which restricts lateral movement between the two. The apparatus is spring biased downwardly to assure firm contact with the ground, and can be raised above the ground by a single lever. The lever carries the biasing spring, and cams lifting bearings on the lever against a lifting plate on the apparatus. The fertilizer is fed by an axially adjustable feed gear rotated by a ground engaging wheel on the apparatus. The feed gear is biased by an adjusting spring against a threaded adjusting knob which sets the axial position of the feed gear.Type: GrantFiled: September 13, 1978Date of Patent: December 16, 1980Assignee: Lambert CorporationInventor: Robert R. Yeager

Patent number: 4180184Abstract: A drop type spreader for handling fertilizer, grass seed or the like for lawns and residential use has a flow control hand grip lever positioned at the spreader handles. The lever is gripped together with one of the handles for initiating flow, and the flow control gate and the lever automatically return to cut off the flow when the lever is released. A tension spring is connected between the hopper and the flow control gate for returning the gate to the flow blocking position when the lever is released. The rate of flow is also controlled from the lever by an adjusting screw, and an indicator is provided at the lever for indicating the selected rate of flow.Type: GrantFiled: March 29, 1978Date of Patent: December 25, 1979Assignee: Lambert CorporationInventors: Richard H. Florer, Thomas E. Via, James M. Weaver

Patent number: 4165697Abstract: A hand held seed planter includes a tubular body and a pair of ground-opening jaws pivotally carried on one end of the body. A seed hopper is slidably mounted on the other end of the body and a ground engaging collar is carried on the one end, surrounding the jaws and mounted for sliding movement on the tubular body. When the soil collar is placed on the ground and a downward force applied to the handle attached to the hopper, the jaws are moved downward into the soil and create a seed opening in the soil. Adjustable pins on the collar control the depth of the opening. At the same time, a seed scoop recess, carrying a seed, is brought into alignment with an opening in a tube which extends through the hopper. A seed is then transferred into the tube, passing through the tubular body and between the jaws, to be planted in the seed opening.Type: GrantFiled: May 30, 1978Date of Patent: August 28, 1979Assignee: Lambert CorporationInventors: Robert R. Yeager, Ronald E. Shaner

Patent number: 4133389Abstract: A hand-held, power driven cultivator includes a housing and cultivator blades which rotate about axes oblique to the vertical axis of the cultivator, the blades extending generally in planes which converge beneath the housing. The cultivator is driven by an electrical motor and has a power train which includes a speed reduction gear arrangement. The cultivator blades may overlap slightly as they rotate and may be formed of hardened metal or plastic. The housing of the cultivator is provided with a skirt which extends outwardly and downwardly about the sides and rear of the housing. The skirt is provided with lower depending side shield portions and a rear rake or spreading portion. The rear rake or spreading portion is formed with notches or teeth to smooth and spread cultivated dirt.Type: GrantFiled: June 29, 1977Date of Patent: January 9, 1979Assignee: Lambert CorporationInventors: Walter F.

Patent number: 3968938Abstract: A system is provided for handling debris, such as twigs, leaves, grass cuttings, refuse and the like comprising a fan-shredding device including a vacuum nozzle, the nozzle being shut off from the fan suction when various units are mounted thereon, such as a hopper and a flexible extension hose. Also, a blower is provided by similarly mounting a cowl on the nozzle and a blower tube on the discharge chute of the fan-shredding device. Shredded debris is bagged in a bag mounted on the discharge chute. On bagging, the shredded debris is compacted by the fan blowing action on the small shredded particles.Type: GrantFiled: September 10, 1974Date of Patent: July 13, 1976Assignee: Lambert CorporationInventors: Walter Franklin Ruhl, Albert W.
