Articulated Plow With Horizontal Angularity Between Its Frames
View pageUS Patent:
42719135, Jun 9, 1981
Filed:
Jul 2, 1979
Appl. No.:
6/054645
Inventors:
Keith A. Wheeler - La Porte IN
Dawson W. Hastings - La Porte IN
Dawson W. Hastings - La Porte IN
Assignee:
Allis-Chalmers Corporation - Milwaukee WI
International Classification:
A01B 6502
US Classification:
172633
Abstract:
The horizontal diagonal angle (z) of the rear frame (16) of an articulated plow (11) is greater than the horizontal diagonal angle (y) of the front frame (14), thus providing a lead angle (x) between the frames (14, 16). This construction reduces the overcut by the plow bottoms (17) that would otherwise occur due to the lateral flexing of the rear frame (16). The lead angle (x) can be adjusted between predetermined minimum and maximum values by moving an eccentric (51) between predetermined positions of pivotal adjustment. The eccentric (51) is part of a pivot joint (33) which together with a pivot joint (32) establishes the transverse pivot axis (31) between the articulated plow sections (12, 13).
Plow With Correlated Pull Bar Adjustment And Support Wheel Steering
View pageUS Patent:
43018726, Nov 24, 1981
Filed:
Aug 29, 1980
Appl. No.:
6/182604
Inventors:
Dawson W. Hastings - La Porte IN
Robert L. Wagner - Bloomington IN
Robert L. Wagner - Bloomington IN
Assignee:
Allis-Chalmers Corporation - Milwaukee WI
International Classification:
A01B 6900
A01B 6322
A01B 6332
A01B 6322
A01B 6332
US Classification:
172290
Abstract:
An articulated plow is provided with a laterally swingable pull bar (31) and steerable intermediate support wheels (46, 47) which are controlled by a hydraulic system providing correlated movement through parallel connected hydraulic jacks (37, 66). A latch mechanism (86) for releasably securing the pull bar (31) in its plowing position of adjustment is operated by the pull bar control jack (37) through an operating lever (41) having a lost motion connection with a spring loaded latch pin (87). A locking plate (131) is provided to automatically lock the latch pin (87) in its retracted position when the pull bar (31) is moved to its transport position.
Articulated Plow With Central Support Providing Counter Moment For Rear Section
View pageUS Patent:
42666180, May 12, 1981
Filed:
Sep 4, 1979
Appl. No.:
6/072422
Inventors:
Keith A. Wheeler - La Porte IN
Dawson W. Hastings - La Porte IN
Dawson W. Hastings - La Porte IN
Assignee:
Allis-Chalmers Corporation - Milwaukee WI
International Classification:
A01B 1514
US Classification:
172314
Abstract:
An articulated plow has a front section 12 supported at its front end by a ground engaging furrow wheel 19, a rear section 13 supported at its rear end by a ground engaging furrow wheel 22, pivot joints 32, 33 interconnecting the diagonally disposed frames 14, 16 of the end-to-end front and rear sections 12, 13 on a transverse articulation axis 31 and central support wheels 23, 24 which contact the ground forwardly of the articulation axis 31 to produce a counter moment acting on the rear section 13 to counteract the tendency of the rear plow bottoms to operate at a reduced plowing depth.
Implement Frame With Caster Wheel And Lock Therefor
View pageUS Patent:
41191560, Oct 10, 1978
Filed:
Dec 13, 1976
Appl. No.:
5/749723
Inventors:
Keith A. Wheeler - La Porte IN
Dawson W. Hastings - La Porte IN
Dawson W. Hastings - La Porte IN
Assignee:
Allis-Chalmers Corporation - Milwaukee WI
International Classification:
A01B 6322
US Classification:
172386
Abstract:
A latch mechanism is provided for locking the front furrow wheel of a plow when the plow frame is in its lowered plowing position. The latch mechanism is inoperative when the plow frame is raised to its transport position, thus permitting the castered furrow wheel support to freely rotate about the vertical spindle pivot axis. A latch is pivoted to the upper end of the vertical spindle about a horizontal axis and has a downwardly extending finger adapted to drop into a recess in a flat ramp on the upper link of a parallel lift linkage for the castered furrow wheel.
