US Patent:

57462771, May 5, 1998

Filed:

Nov 6, 1995

Appl. No.:

8/554301

Inventors:

Richard L. Howell - Garden Grove CA

International Classification:

F21C 512

US Classification:

173184

Abstract:

Augering device is disclosed which is useful for drilling holes in the ground at various angles under relatively low overhead or ceiling conditions. The device is suitable for mounting on a wide variety of vehicles ranging from the bed of small pickup trucks to very large track type caterpillars with booms. The device has an extendable mast powered by a downcrowding mechanism, a kelly assembly, and a kelly rotating mechanism. The extendable mast has a first mast member and a second mast member. A downcrowding hydraulic cylinder extends the second mast member away from the first mast member and pulls the second mast member towards the first mast member. The telescoping kelly sections include at least an outer kelly section and an inner kelly section. The outer kelly section has an axis parallel to but spaced apart from the axis of the first mast member. A bearing rotatable supports the outer kelly section and prevents axial displacement of the outer kelly section relative thereto.

Appl. No.:

7/211691

Inventors:

Richard L. Howell - Garden Grove CA

International Classification:

E21C 512

US Classification:

173 89

Abstract:

A downcrowdable telescopic augering apparatus and drilling rig is disclosed that has a low overhead requirement and yet can drill large diameter holes ot great depths. The invention is especially useful for drilling foundation holes. One embodiment of the invention can ready over walls and in-place equipment for drilling holes. One embodiment of the invention can drill holes at almost any angle desired into the earth. One embodiment can drill holes on steeply inclined terrains. Because of its low overhead requirement, the drilling rigs of this invention can be used inside existing building without damaging the ceilings or roofs to drill foundation holes for mounting new machinery. The downcrowd means of this invention does not substantially increase the height of the augering apparatus or drilling rig.

International Classification:

B65H 3910

US Classification:

Abstract:

A moving bin sheet sorter has rotatable cams which engage portions of the sorter trays to move the trays at the ends adjacent to a sheet entry location between positions at which those tray ends are closely spaced above and below the sheet entry location and further spaced apart at the sheet entry location for receiving sheets supplied from a copier or printer. The cams are driven by an electric motor which is controlled to operate at a low speed as the trays are initially engaged and disengaged from the cam and a high speed during the major movement of the trays, thereby reducing noise resulting from high speed impact and shock loading of the cams and cooperative portions of the trays, as well as reducing noise resulting from high speed impact of said cooperative portions of the trays in guides for the trays.
