Publication number: 20100052289Abstract: A trailer having a frame extending along a longitudinal axis and having a front end and a rear end, a steering linkage coupled to the frame, a pair of front wheel assemblies coupled to the front end of the frame, and a pair of rear wheel assemblies coupled to the rear end of the frame. Each wheel assembly includes a wheel carrier having a pivot member pivotally coupled to the frame along a steering axis, the wheel carrier being coupled to the steering linkage so that actuation of the steering linkage pivots the wheel carrier about the steering axis, and a wheel rotatably coupled to the wheel carrier along a wheel axis. The wheel axis is oriented approximately perpendicular to the steering axis, and the wheel axis is offset from the steering axis.Type: ApplicationFiled: August 26, 2008Publication date: March 4, 2010Applicant: 1708828 ONTARIO LTD.

Patent number: 7568878Abstract: A loader boom arm for a material handling vehicle used in the agricultural or construction industries includes a post attachable to the vehicle, a lower arm pivotally connected to the post, an upper arm pivotally connected to the lower arm, a pivoting mechanism coupled to the post and the lower arm, and a link arm pivotally connected to the post and to the upper arm. The boom arm is raised and lowered in an angular direction of rotation by pivoting the lower arm about the post using the pivoting mechanism. As the lower arm is pivoted, the link arm causes the upper arm to pivot relative to the lower arm such that the upper arm pivots further in the direction of angular rotation than the lower arm, thus changing the angle between the lower arm and upper arm.Type: GrantFiled: April 10, 2006Date of Patent: August 4, 2009Assignee: Frey Industries LimitedInventor: Oscar Frey

Patent number: 7493710Abstract: The left and right sideblades are hinged to the mainblade about vertical axes, and can pivot each through 180°. The sideblades are rotated by means of left and right hydraulic rotary actuators. The actuator includes a piston formed with helical splines, which drive a rotor sleeve of the actuator to rotate in a single-plane-circle when the piston is driven axially. The journal bearings in the rotary actuator are supplemented by bearings provided in a coaxial lower hinge, which are of much greater journal capacity than the bearings in the rotary actuators. The lower hinge protects the hydraulic rotary actuator from shocks due to the sideblade impacting against a kerb.Type: GrantFiled: March 15, 2007Date of Patent: February 24, 2009Assignee: 1708828 Ontario Inc.Inventors: Oscar Frey, Ryan Earl Frey

Patent number: 7354237Abstract: A loader boom arm for a material handling vehicle used in the agricultural or construction industries includes a post attachable to the vehicle, a lower arm pivotally connected to the post, an upper arm pivotally connected to the lower arm, a pivoting mechanism coupled to the post and the lower arm, and a link arm pivotally connected to the post and to the upper arm. The boom arm is raised and lowered in an angular direction of rotation by pivoting the lower arm about the post using the pivoting mechanism. As the lower arm is pivoted, the link arm causes the upper arm to pivot relative to the lower arm such that the upper arm pivots further in the direction of angular rotation than the lower arm, thus changing the angle between the lower arm and upper arm. The subject loader boom arm allows an operator to move material in a bucket attached to the boom arm to locations of higher elevation and further reach than typically available with conventional boom arms.Type: GrantFiled: July 22, 2005Date of Patent: April 8, 2008Assignee: Frey Industries LimitedInventor: Oscar Frey

Publication number: 20020074758Abstract: Disclosed is a suspension system for equalizing the load on a vehicle, preferably a farm wagon. The system comprises four double acting hydraulic cylinders at each of the four corners of a farm wagon which are plumbed in a closed loop circuit. Fluid displaces between the four cylinders during use in order to maintain equilibrium within the system. The displacing fluid results in movement of each respective corner and wheel with respect to the ground.Type: ApplicationFiled: December 17, 2001Publication date: June 20, 2002Inventor: Oscar Frey
