Abstract: A vacuum pod system for supporting a workpiece. A work table is provided with a shouldered opening formed therein in communication with a vacuum source. A pod is provided having a first longitudinal portion of a first outside diameter which seats on the shoulder in the opening, and a second longitudinal portion for supporting the workpiece, the second portion having a second outside diameter unequal to the first diameter. A passageway extends through the pod for providing communication between the first and second portions so that when the workpiece is supported on the second portion, a vacuum generated by the vacuum source creates a suction force which secures the workpiece to the pod.

Abstract: Window latching apparatus for securing a cab window above the head of an operator includes a rotatable cam mounted to a side roof rail of the cab. A pin projecting from frame of window engages a slot in the cam. Lever means including spring biasing means are provided to interlock with cam to retain window in safely stowed position overhead of the operator.

Abstract: A door latch for a cab whereby a door is held in the open position by the latch which is operative by a handle passing through the cab having linear motion to operate a pawl having pivotal motion for engaging a detent on the door. Further, the handle mounting is a compact one with biasing means and a seal thereon all enclosed within a segment of the cab wall.

Abstract: A control module for tractors in which the various controls for operating the tractor are supported in a group for convenient operation by the operator of the tractor and may be installed as a unit in the tractor relative to an operator station that is flexibly supported relative to the main body of the tractor. The various controls are resiliently and flexibly connected to control various devices making up the unsuspended main body of the tractor. The tractor may have either an enclosed cab or an open platform forming an operator station resiliently mounted to the unsuspended main body of the tractor to inhibit the transmission of vibration, shock loads and noise, and the module is supported from the station to minimize relative movement between the operator and the controls. The controls are connected by flexible means serving to dampen the transmission of vibrations and the like from the unsuspended main body of the tractor.

Abstract: A latching arrangement for complemental top and bottom door panels on a cab of a tractor includes a handle which is pivotally mounted to the top door panel between operative and inoperative positions. Biasing means in the form of a coil spring mounted between the handle member and the door normally urges the member to its inoperative position. An element connected to the lower door panel and defining a recess to receive the handle member operates to position the upper door in angular relationship to the complemental lower door member to ventilate the cab. A peripheral portion of the handle which is received in the connecting element is disposed at an angle relative to the axis about which the handle pivots to thereby define the angle at which the complemental door panels are held apart.
