Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
180 words
A manual lockout mechanism for engaging a reverse gear of a drive transmission of a rear engine vehicle wherein said drive transmission is associated with said engine comprising: a shift shaft extending forwardly from said transmission; a pivotal shift lever means coupled with said shift shaft and extending upwardly into said vehicle; restraining plate means mounted on said vehicle including an opening therethrough, through which said shift lever means projects whereby said shift lever means may be laterally restrained during forward gear shifting; lockout means on said shift lever adapted to be moved vertically independently of said shift lever and override said restraining plate means whereby said shift lever means may be moved and in turn impart forward and angular movement to said shift shaft causing engagement of said reverse gear; and finger control means on said shift lever means linked to said lockout means adapted to move said last named means, and wherein said lockout means includes a shiftable stop pin adapted to be moved from an at rest posItion vertically above the restraining plate to a release position.
Claim 2
Dependent Claim
180 words
A manual lockout mechanism for engaging a reverse gear of a drive transmission of a rear engine vehicle wherein said drive transmission is associated with said engine comprising: a shift shaft extending forwardly from said transmission; a pivotal shift lever means coupled with said shift shaft and extending upwardly into said vehicle; restraining plate means mounted on said vehicle including an opening therethrough, through which said shift lever means projects whereby said shift lever means may be laterally restrained during forward gear shifting; lockout means on said shift lever adapted to be moved vertically independently of said shift lever and override said restraining plate means whereby said shift lever means may be moved and in turn impart forward and angular movement to said shift shaft causing engagement of said reverse gear; and finger control means on said shift lever means linked to said lockout means adapted to move said last named means, and wherein said lockout means includes a shiftable stop pin adapted to be moved from an at rest posItion vertically above the restraining plate to a release position.
Claim 3
Dependent Claim
25 words
A mechanism as defined in claim 1 wherein said lockout means includes a spring normally biasing said shiftable stop pin to the at rest position.
Claim 4
Dependent Claim
194 words
A manual lockout mechanism for engaging a reverse gear of a drive transmission of a rear engine vehicle wherein said drive transmission is associated with said engine comprising: a shift shaft extending forwardly from said transmission; a pivotal shift lever means coupled with said shift shaft and extending upwardly into said vehicle; restraining plate means mounted on said vehicle including an opening therethrough, through which said shift lever means projects whereby said shift lever means may be laterally restrained during forward gear shifting; lockout means on said shift lever adapted to be moved vertically independently of said shift lever and override said restraining plate means whereby said shift lever means may be moved and in turn impart forward and angular movement to said shift shaft causing engagement of said reverse gear; and finger control means on said shift lever means linked to said lockout means adapted to move said last named means, and wherein said finger control means on said shift lever includes a spring loaded pushbutton movable normal to the vertical movement of said lockout means and communicating with said lockout means which control means when manually depressed will release said lockout means.
Claim 5
Dependent Claim
194 words
A manual lockout mechanism for engaging a reverse gear of a drive transmission of a rear engine vehicle wherein said drive transmission is associated with said engine comprising: a shift shaft extending forwardly from said transmission; a pivotal shift lever means coupled with said shift shaft and extending upwardly into said vehicle; restraining plate means mounted on said vehicle including an opening therethrough, through which said shift lever means projects whereby said shift lever means may be laterally restrained during forward gear shifting; lockout means on said shift lever adapted to be moved vertically independently of said shift lever and override said restraining plate means whereby said shift lever means may be moved and in turn impart forward and angular movement to said shift shaft causing engagement of said reverse gear; and finger control means on said shift lever means linked to said lockout means adapted to move said last named means, and wherein said finger control means on said shift lever includes a spring loaded pushbutton movable normal to the vertical movement of said lockout means and communicating with said lockout means which control means when manually depressed will release said lockout means.
Claim 6
Dependent Claim
207 words
A manual lockout mechanism for engaging a reverse gear of a drive transmission of a rear engine vehicle wherein said drive transmission is associated with said engine comprising: a shift shaft extending forwardly from said transmission; a pivotal shift lever means coupled with said shift shaft and extending upwardly into said vehicle; restraining plate means mounted on said vehicle including an opening therethrough, through which said shift lever means projects whereby said shift lever means may be laterally restrained during forward gear shifting; lockout means on said shift lever adapted to be moved vertically independently of said shift lever and override said restraining plate means whereby said shift lever means may be moved and in turn impart forward and angular movement to said shift shaft causing engagement of said reverse gear; and finger control means on said shift lever means linked to said lockout means adapted to move said last named means, and wherein said shift lever includes a longintudinal bore, a slidable rod mounted in said bore, an elongated slot in said shift lever and communicating with said bore, said lockout means including a shiftable stop pin mounted on said rod and extending normal to the axis of said rod and projecting through said elongated slot.
Claim 7
Dependent Claim
207 words
A manual lockout mechanism for engaging a reverse gear of a drive transmission of a rear engine vehicle wherein said drive transmission is associated with said engine comprising: a shift shaft extending forwardly from said transmission; a pivotal shift lever means coupled with said shift shaft and extending upwardly into said vehicle; restraining plate means mounted on said vehicle including an opening therethrough, through which said shift lever means projects whereby said shift lever means may be laterally restrained during forward gear shifting; lockout means on said shift lever adapted to be moved vertically independently of said shift lever and override said restraining plate means whereby said shift lever means may be moved and in turn impart forward and angular movement to said shift shaft causing engagement of said reverse gear; and finger control means on said shift lever means linked to said lockout means adapted to move said last named means, and wherein said shift lever includes a longintudinal bore, a slidable rod mounted in said bore, an elongated slot in said shift lever and communicating with said bore, said lockout means including a shiftable stop pin mounted on said rod and extending normal to the axis of said rod and projecting through said elongated slot.
Claim 8
Dependent Claim
27 words
A mechanism as defined in claim 4 wherein said shift lever includes a stop disc extending normal to the axis of said lever adjacent said shiftable stop-pin.
