Abstract
TWO-WAY CONTROL LEVER ROTATABLE IN CAB WALL FOR SOUND SEALING
Abstract of the Disclosure A two-way control lever includes a pair of shafts journalled in a cab wall for tranmitting motion from a handle of the lever to control functions located exteriorly of the cab. The pair of shafts and their support bearings adequately seal holes provided in a cab wall section for their installation for preventing the transmission of noise therethrough.

Description
1 TWO-WAY CONTROL LEVER ROTAT~BLE IN C~B WALL FOR SOUND SEAL:[NG
Background of the Invention The present lnvention relates to control levers and more particularly relates to control levers used within cabs for effecting control of devlces outside of cabs.
One of the mos-t effective methods of noise reduction in a vehicle cab is the complete closing of all openings between noise sources and an operator in the cab. One area required to be closed or sealed is around control levers or their associated linkage which pass through the cah walls.
This elosing or sealing has historically been done, especially in the case of control levers having two degrees of freedom, with the use of rubber boots or slits in foam in which the levers or linkage travel. This method is not always efEective due to loose fits or worn parts.
Summar~ of the Invention Aceording to the present invention, there is provided a two-way eontrol lever mounted in a cab in a novel manner.
~ n objeet of the invention is to provide a two-way control lever within a eab and mounted so as to eontrol functions located exteriorly of the eab with the parts of the lever which penetrate the cab wall being adequately sealed without the need for rubber boots or foam.
A more specific object is to provide a lever having two degrees of freedom and having a pair of output shaft seetions rotatably mounted in the cab wall for transferring control lever movements to functions located exteriorly of the eab.
These and other objeets will beeome apparent from a reading - of the ensuing description together with the appended drawing.
Brief Deseription of the Drawing The sole figure is a perspective view of a two-way control lever and eab wall combination eonstrueted aeeording to the prineiples of the present invention.
Description of the Preferred Embodiment Referring now to the drawing, there is shown a eab wall seetion 10 and a eontrol lever 12 loeated within the cab. The wall seetion 10 ineludes a pair of vertieal wall portions 14 and 16, respeetively, whieh run perpendieular to eaeh other~ The wall portions 14 and 16 are respeetively provided wi~h holes 18 ~`
-- 1 -- ~,~
s 1 and 20 which are disposed along horizontal axes 22 and 24 which are located in vertical planes -that intersect within the cab.
The lever 12 includes first and second shafts 26 and 27 whlch are respectively rotatably mounted in bearings 28 and 29 respectively provided in the holes 18 and 20. Secured to -the shaft 26 is a yoke 30 and secured to the shaft 27 is a yoke 32.
An upright control handle 34 is located centrally between the legs of the yokes 30 and 32 and has a first pair of oppositely projecting stub shafts 36 rotably mounted in the yoke 30 for rotation about an axis 37 located in the vertical plane that contains the axis 24, and has a second pair of oppositely projecting stub shafts 3~ rotatably mounted in the yoke 32 for rotation about an axis 39 located in the vertical plane that contains the axis 22.
It will be appreciated then that the shaft 26 may be rotated to control a function connected thereto by moving the control handle 34 in a direction crosswise to the axis 39. The lever then will rotate about the axis 22 to effect rotation of the shaft 26 without imparting any motion to the shaft 27. Similarly, movement of the handle 34 in a direction crosswise to the axis 37 will result in the handle rotating the shaft 27 without imparting any rotation to the shaft 26.
Since the movements of the shafts 26 and 27 are purely rotational, the holes in the cab wall section 10 are effectively sealed by the shafts and their respective support bearings.
