Filed:

Sep 8, 1981

Appl. No.:

6/299904

Inventors:

Robert Sorensen - Glen Ellyn IL
Edward A. Barrett - Glendale Heights IL
Thomas J. Scarnato - Barrington IL

Assignee:

International Harvester Co. - Chicago IL

International Classification:

B65G 5358

US Classification:

406100

Abstract:

A centrifugal blower has an offset between a housing rim sheet and discharge conduit outer wall. A vertical panel attached to the rim sheet guides the feed material into the silo pipe center portion without contacting the conduit outer wall and discharge duct. An air inlet for secondary air flow is provided in this offset to supplement the principal air flow entering through material feed inlet into the blower and to provide an air cushion between the air-borne material and outer wall, as well as the initial portion of the discharge duct.

International Classification:

A01D 3508

US Classification:

56 104

Abstract:

A pitman mower has a hitch frame, a drag bar, a cutterbar pivotally attached to the drag bar for pivotal movement in the transverse vertical plane and a drive mechanism for the cutterbar mounted on the drag bar. A pair of fore-and-aft extending links interconnect the hitch frame and drag bar in a generally horizontal four bar parallel linkage, the left link being resilient in the transverse direction, preferably comprising a leaf spring, having one end rigidly connected to its adjacent member. The right link comprises a breakaway pull bar assembly rotatable about an axis generally longitudinal thereof and has a float spring and lifting chain connected thereto and disposed to rotate the pull bar against the load imposed thereon by a gag link connected to the pull bar away from the axis of rotation thereof and extending to the cutterbar to control its rotation about the drag bar.

International Classification:

A01D 3516

US Classification:

56 104

Abstract:

A cutterbar control system for an agricultural or highway mower having a longitudinally rotatable pull bar connecting the tractor hitch frame and the drag bar. The cutterbar gag link is connected to the pull bar at a point removed from its axis of rotation and a float spring and lifting chain are mounted to the pull bar to rotate it against the load imposed by the cutterbar gag link. The pull bar is extendible in response to overloads imposed on the cutterbar.
