Total Claims: 16
Claim 1
Independent Claim
216 words
A single lever control apparatus having a housing for operating the clutch and throttle of an engine comprising a transmission shaft (6) adjustably carrying a control lever (1), a clutch operating member and a throttle operating member to be driven by said transmission shaft (6), and a rack gear (43), said transmission shaft (6) having a transmission gear 5 and a locking face (38), said throttle operating member being rotatably supported on a stationary pivot (31) and having gears (25), a locking face (28) and an arm (26) to be connected to the throttle, the locking face (28) of said throttle operating member (32) be engageable with the locking face (38) of said transmission shaft to lock said throttle operating member (32) with the teeth (25) thereof meshing with said rack gear when said control lever (1) is in neutral position, the teeth (14) of said transmission gear being meshable with the teeth (25) of said throttle operating member (32) to rotate said throttle operating member when said control lever (1) is pivoted toward one direction, the teeth (14'') of said transmission gear being meshable with said rack gear (43) to rotate said throttle operating member in the same direction through said rack gear (43) when said control lever (1) is pivoted toward the other direction.
Claim 2
Dependent Claim
216 words
A single lever control apparatus having a housing for operating the clutch and throttle of an engine comprising a transmission shaft (6) adjustably carrying a control lever (1), a clutch operating member and a throttle operating member to be driven by said transmission shaft (6), and a rack gear (43), said transmission shaft (6) having a transmission gear 5 and a locking face (38), said throttle operating member being rotatably supported on a stationary pivot (31) and having gears (25), a locking face (28) and an arm (26) to be connected to the throttle, the locking face (28) of said throttle operating member (32) be engageable with the locking face (38) of said transmission shaft to lock said throttle operating member (32) with the teeth (25) thereof meshing with said rack gear when said control lever (1) is in neutral position, the teeth (14) of said transmission gear being meshable with the teeth (25) of said throttle operating member (32) to rotate said throttle operating member when said control lever (1) is pivoted toward one direction, the teeth (14'') of said transmission gear being meshable with said rack gear (43) to rotate said throttle operating member in the same direction through said rack gear (43) when said control lever (1) is pivoted toward the other direction.
Claim 3
Dependent Claim
54 words
The apparatus as set forth in claim 1, wherein a holder (61) or adjuster (73) is secured to the outer cable (77) of a cable (60) for the throttle at the position where the outer cable extends into said housing (9) so as to adjust the throttle range by moving only the outer cable.
Claim 4
Dependent Claim
37 words
The apparatus as set forth in claim 1, wherein said throttle operating member (32) has an arm (26'') to be connected to the throttle in symmetrical relation to the arm (26) with respect to said pivot (31).
Claim 5
Dependent Claim
109 words
The apparatus as set forth in claim 1, wherein said clutch operating member (30) is rotatably supported on said stationary pivot (31) and has teeth (50), arcuate concave faces (52, 52'') and an arm (47) to be connected to the clutch, said teeth (50) being meshable with a gear (16) to be driven by said transmission shaft when said control lever (1) is in neutral position, said arcuate concave faces (52, 52'') being engageable with the circumferential faces (51, 51'') of said gear (16) to lock said clutch operating member (30) when said control lever (1) is pivoted a given angle from neutral position toward forward and backward positions.
Claim 6
Dependent Claim
43 words
The control apparatus as set forth in claim 4, wherein said throttle operating member (32) is locked while said clutch operating member (30) is in operation and said clutch operating member (30) is locked while said throttle operating member (32) is in operation.
Claim 7
Dependent Claim
90 words
The control apparatus as set forth in claim 4, wherein the gear (16) to be driven by said transmission shaft (6) is integrally formed with a shaft (17), said shaft (17) extending through said transmission shaft (6) rotatably and slidably in the axial direction and having an exposed end to provide a push button, said push button when depressed being capable of disengaging said clutch operating member (30) from said gear (16) only in neutral position, said clutch operating member (30) being locked by said gear (16) when thus disengaged.
Claim 8
Dependent Claim
58 words
The control apparatus as set forth in claim 4, wherein the arm (47) of said clutch operating member (30) slidably carries a slide piece (53) to be connected to the clutch, said slide piece (53) being continuously adjustable with respect to its position relative to said pivot (31) by an adjusting bolt (33) screwed into said slide piece.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
44 words
The control apparatus as set forth in claim 4, wherein said throttle operating member (32) and said clutch operating member (30) are formed with arms (26'') and (47'') in symmetrical relation to the arms (26 and 47) with respect to their pivot (31) respectively.
Claim 11
Dependent Claim
55 words
The control apparatus as set forth in claim 4, wherein a holder (61) or adjuster (73) is secured to the outer cable (77) of a cable (60) for the throttle at the position where the outer cable extends into said housing (9) so as to adjust the throttle range by moving only the outer cable.
Claim 12
Dependent Claim
