Patent number: 8919735Abstract: A scissor-stacked assembly and a method of routing a cable thereto is provided. The assembly includes a plurality of inner arms and outer arms that are connected to one another by retaining pins. The retaining pins are located at central portions of the inner and outer arms and retained by a cap and retaining means. The arms create a plurality of pantographs that allow the assembly to move between a collapsed position and a raised position. Also included is a method of routing a cable through the assembly. The method includes the use of wire forms or tie bars to affix a cable or hose to the wire form or tie bar. The hose is wrapped around crosstubes connecting right and left side arms of the assembly and is attached to the wire forms or tie bars by the use of zip ties or hose clamps.Type: GrantFiled: February 24, 2011Date of Patent: December 30, 2014Assignee: Rosenboom Machine & Tool, Inc.Inventors: Darin Michael Rosenboom, Dean Earl Reinking, Daniel Jon Van Regenmorter

Patent number: 8904917Abstract: A fluid-powered, helical rotary actuary is provided. The actuary includes a housing, a shaft with output ends positioned in the housing, and a piston sleeve surrounding the shaft and also positioned within the housing. The shaft includes a groove for receiving a collar. The collar creates a false shoulder such that the shaft is able to have the same diameter along the length of the shaft, thus allowing for a larger working area and more torque output density. The actuary also includes a support ring positioned on the shaft near the splined portion of the output end. The support ring is used to stabilize the attachment of an external member, and also to protect the shaft from damage caused by the splined receiving portion of the external member, or hub.Type: GrantFiled: April 15, 2011Date of Patent: December 9, 2014Assignee: Rosenboom Machines & Tool, Inc.Inventors: Darin Michael Rosenboom, Ryan Lee Bolkema, Daniel Jon Van Regenmorter

Patent number: 7828353Abstract: Slidably mounted within the cylinder 108 of the accumulator 46 is a piston 48. A spring 50 is positioned behind the piston 48, which biases the piston 48 toward port 56. The portion of the cylinder 108 occupied by spring 50 is vented to the atmosphere by breather 52, which allows air to pass in and out of cylinder 108. As a result of the spring 50 acting on the piston 48, fluid is collected, stored, and released from the cylinder 108 under pressure. It should be understood that the accumulator could collect, store and release fluid under pressure using energy storage devices other than spring 50. For example, the accumulator 46 could be gas.Type: GrantFiled: April 4, 2007Date of Patent: November 9, 2010Assignee: Rosenboom Machine & Tool, Inc.Inventors: Darin M. Rosenboom, Joshua L.

Patent number: 7213504Abstract: This invention is a bi-directional hydraulic actuator comprising a piston assembly positioned within a housing. The piston assembly is configured to move linearly within the housing. A gland is operatively connected to the piston assembly. The gland is configured as a rigid longitudinally annular member with a first end, a second end, a sidewall and is open on the first end and substantially closed on the second end which forms an inside and an outside of the annular member. The gland is further configured with a lip extending from around the outside of the first end of the gland. A pressurizing fluid exerts pressure on the inside of the gland to move the piston assembly a first direction, then, a fluid exerts pressure on the outside of the gland and the lip of the gland to move the piston assembly opposite the first direction.Type: GrantFiled: May 2, 2005Date of Patent: May 8, 2007Assignee: Rosenboom Machine & Tool, Inc.Inventors: Darin Michael Rosenboom, Brian D.
