Abstract
Abstract A lateral tube transmission control which is adopted for use on conventional automotive transmissions which consists of individual shift levers for each pair of gear sets. Each lever is equipped with a locking device which automatically locks the lever in either a neutral position or an engaged position when the lever is moved to a predetermined position. The levers transmit this movement to the transmission linkages through a concentrically mounted shaft and tubes.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
An apparatus for selecting tansmission gear positions comprising: (a) one lever; (b) one arm; (c) a shaft with a diametrical hole; (d) a housing with a transverse hole; and (e) a locking means which simultaneously engages the diametrical hole in the shaft and the transverse hole in the housing for locking automatically the position of said lever relative to said housing to restrain said lever from moving relative to said housing for positively holding the gear selection made by positioning said lever.
Claim 2
Independent Claim
82 words
An apparatus for selecting tansmission gear positions comprising: (a) one lever; (b) one arm; (c) a shaft with a diametrical hole; (d) a housing with a transverse hole; and (e) a locking means which simultaneously engages the diametrical hole in the shaft and the transverse hole in the housing for locking automatically the position of said lever relative to said housing to restrain said lever from moving relative to said housing for positively holding the gear selection made by positioning said lever.
Claim 3
Dependent Claim
227 words
An apparatus as set forth in claim 1 comprising: (a) a first lever which is attached at one end to; (b) a tube with a diametrical hole; (c) A second lever which is attached at one end to; (d) a shaft with two diametrical holes, said shaft being mounted rotatably inside said tube; (e) a housing, with two transverse holes, in which said shaft and tube are rotatably mounted. (f) two arms, the first of which is attached to said shaft at the end opposite to that whereon said second lever is attached and the second of which is attached to said tube at the end opposite to that whereon said first lever is attached; (g) a first locking means which simultaneously engages one diametrical hole in the shaft, the diametrical hole in the tube and one transverse hole in the housing when engaged for automatically locking the position of said first lever relative to said housing when said first lever is positioned to select high gear in a conventional automotive transmission; and (h) a second locking means which simultaneously engages the second diametrical hole in the shaft and the second transverse hole in the housing when engaged for automatically, locking the position of said second lever relative to said housing when said second lever is positioned to select the neutral position in a conventional automotive transmission.
Claim 4
Dependent Claim
63 words
An apparatus as set forth in claim 2 comprising; (a) at least three levers; (b) at least two tubes; (c) at least three arms each of which is attached to a shaft or tube at the end opposite to the point of attachment of said levers; (d) at least three locking means for locking the position of the levers relative to the housing.
