20120087769, Apr 12, 2012

Filed:

Oct 12, 2010

Appl. No.:

12/902831

Inventors:

William B. Michaels - Monee IL, US
Patrick A. Burnett - Crete IL, US

International Classification:

B66F 9/18

US Classification:

414621

Abstract:

An apparatus such as an attachment for a skid steer used to remove and transport sidewalk segments may include a plurality of translating forks configured to drive into the ground surrounding the segment. The apparatus also may include a plurality of bearing surfaces for contacting and applying an upwardly directed force to the underside of the segment. Each of the forks may be tapered to slide into the ground more easily, and each bearing surface may be removably attached to the apparatus for easy repair or replacement. By limiting the amount of the apparatus that penetrates the ground to the plurality of forks, the apparatus provides a method of removing sidewalk segments that is quick and efficient, resulting in minimal disturbance to the ground and easier preparation for pouring a new sidewalk segment.

US Classification:

414741, 414738

Abstract:

An apparatus such as an attachment for a skid steer used to remove and transport curb segments may include a fork configured to drive into the ground behind the curb. The apparatus also may include a curb restrainer configured to engage the upper side of the curb. Each of the forks may be tapered to slide into the ground more easily, and each bearing surface may be removably attached to the apparatus for easy repair or replacement. Additionally, the curb restrainer may both translate and rotate to adjust for various curb thicknesses in order to position the restrainer against the top of the curb, preferably in the curve of the curb. By limiting the amount of the apparatus that penetrates the ground, the apparatus provides a method of removing curbs that is quick and efficient, resulting in minimal disturbance to the ground and easier preparation for pouring a new curb.

Assignee:

Sundstrand Corporation - Rockford IL

International Classification:

B60T 712

US Classification:

192 8R

Abstract:

This invention relates to an energy absorbing ratchet for a bidirectional no-back apparatus which includes in combination a fixed support, a rotatable input member and a rotatable output member. The input member includes an input plate which has integral therewith a pair of release pins. An output plate is coupled to the output member. The input plate and the output plate have a torque transmission device coupled therebetween. The fixed support has an energy absorbing means coupled to a ratchet ring. The ratchet ring is positioned between the input and the output plate. The output plate has thereon a pair of moveably mounted pawl members for cooperative engagement with the ratchet ring to thereby engage the ratchet ring when the no-back apparatus is at rest, and whenever a backdriving load is delivered from the output member to the output plate. The pawl members are released from the ratchet ring by the cooperative engagement with the release pins upon bidirectional rotation of the input member.
