Patent number: 7419109Abstract: An apparatus for mounting hammers to a hammer mill having at least one hammer provided for attachment to a hammer mill, the at least one hammer having an opening disposed in one end thereof corresponding to a pivot axis, the opening being of a first diameter. A sleeve having a central opening therein is operatively attached to the hammer mill, the sleeve being disposed in the opening in the one end of the at least one hammer. The sleeve has a first cylindrical outer surface with a second diameter, the second diameter being only slightly smaller than the first diameter of the opening in one end of the at least one hammer. The sleeve has a second cylindrical outer surface with a third diameter, the third diameter being larger than said second diameter. A shoulder on the sleeve extends from the second cylindrical outer surface to the third cylindrical outer surface. An annular groove is disposed in the first cylindrical outer surface.Type: GrantFiled: September 12, 2006Date of Patent: September 2, 2008Assignee: Jacobs CorporationInventors: Ron R.

Patent number: 4099769Abstract: An apparatus for adjusting tension in an elongated bicycle saddle. The apparatus includes a frame underlying the saddle and having one end in abutting contact with a flaired trailing portion of the saddle and the other end in proximity to a narrow leading portion of the saddle. An adjustment yoke is connected to the other end of the frame and provides a bearing seat for abutting reception of an adjustment member. A thrust bearing member extends through a downwardly contoured tip portion of the saddle and carries the adjustment member such that axial tension of the saddle may be facilely adjusted through the tip of the bicycle saddle.Type: GrantFiled: March 7, 1977Date of Patent: July 11, 1978Assignee: The Jacobs CorporationInventor: David L. Jacobs
