Abstract
Abstract A control means with a spring lever for use in setting a set of gears in two different positions. The lever is of a spring material which is resilient and capable of being sprung into a position for storing energy whereby the lever will urge the gears into one position, or the lever will hold the gears in one position, to the extent of the spring force available in the lever. A plate member engages the handle of the lever and has two positions for holding the lever in either of the two positions, and the plate is adjustably mounted.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
210 words
A control means with a spring lever for use in setting a device in two different positions, comprising a pivotally mounted lever of a spring material which is resilient and thereby capable of bending throughout its length to be recoverably sprung into a position for storing energy in said lever, said lever having opposite end portions extending on opposite sides of and away from the pivot mounting and with one of said end portions being a handle and with the other of said end portions including a connection portion arranged to connect to the device being controlled by said control means, and a member disposed adjacent the extending end of said handle and having two notches for lever-restraining positions and with said notches faced oppositely from each other and arranged and spaced apart in the directions transverse to the axis of pivot of said lever and spaced apart a distance within the bending capacity of said lever, for engaging said handle alternately in said two notches and thereby restrain said handle when said connection portion of said lever is cconnected to and restrained by said device, and said member having a slot extending between said notches for sliding movement and control of said handle in its movement between said notches.
Claim 2
Dependent Claim
210 words
A control means with a spring lever for use in setting a device in two different positions, comprising a pivotally mounted lever of a spring material which is resilient and thereby capable of bending throughout its length to be recoverably sprung into a position for storing energy in said lever, said lever having opposite end portions extending on opposite sides of and away from the pivot mounting and with one of said end portions being a handle and with the other of said end portions including a connection portion arranged to connect to the device being controlled by said control means, and a member disposed adjacent the extending end of said handle and having two notches for lever-restraining positions and with said notches faced oppositely from each other and arranged and spaced apart in the directions transverse to the axis of pivot of said lever and spaced apart a distance within the bending capacity of said lever, for engaging said handle alternately in said two notches and thereby restrain said handle when said connection portion of said lever is cconnected to and restrained by said device, and said member having a slot extending between said notches for sliding movement and control of said handle in its movement between said notches.
Claim 3
Dependent Claim
75 words
The control means with a spring lever as claimed in claim 1, wherein said lever is L-shaped and has its comparable upright portion thereof defined by terminating in said handle, a pivot mounting engaged with the comparable horizontal portion of the L-shaped lever, and with the length of said lever along said upright portions thereof being greater than the spacing between said restraining positions on said member, for creating strong spring energy in said lever.
Claim 4
Dependent Claim
55 words
The control means with a spring lever as claimed in claim 1, including an adjustment mounting connected with said member, and with said member having adjustment movement in the directions of movement of said lever handle for adjustably positioning said restraining positions relative to said lever and thereby vary the restrained positions of said lever.
Claim 5
Dependent Claim
50 words
The control means with a spring lever as claimed in claim 3, wherein said member is a plate and it includes mounting slots extending parallel to the first said slot, and including mounting bolts engaged with said plate and extending through said mounting slots and thereby providing an adjustment mounting.
Claim 6
Dependent Claim
196 words
A control means with a spring lever, comprising a plurality of gears movably related to each other for movement into and out of driving engagement with each other, a pivotally mounted lever of a spring material throughout its length and capable of being flexed along its length for storing energy in said lever, said lever having opposite end portions extending on opposite sides of and away from the pivot mounting, one extending end of said lever being connected with one of said gears for movement of said gear relative to another of said gears, the end of said lever opposite said one end extending to an end portion presenting a handle maneuverable by a person for pivotal action of said lever, and a restraining member disposed adjacent said end portion and having two restraining positions arranged thereon and spaced apart in the directions transverse to the axis of pivot of said lever and spaced apart a distance within the bending capability of said lever, for engaging said end portion alternately at said two restraining positions and thereby restrain said end portion when said connection portion of said lever is connected to and restrained by said gears.
Claim 7
Dependent Claim
196 words
A control means with a spring lever, comprising a plurality of gears movably related to each other for movement into and out of driving engagement with each other, a pivotally mounted lever of a spring material throughout its length and capable of being flexed along its length for storing energy in said lever, said lever having opposite end portions extending on opposite sides of and away from the pivot mounting, one extending end of said lever being connected with one of said gears for movement of said gear relative to another of said gears, the end of said lever opposite said one end extending to an end portion presenting a handle maneuverable by a person for pivotal action of said lever, and a restraining member disposed adjacent said end portion and having two restraining positions arranged thereon and spaced apart in the directions transverse to the axis of pivot of said lever and spaced apart a distance within the bending capability of said lever, for engaging said end portion alternately at said two restraining positions and thereby restrain said end portion when said connection portion of said lever is connected to and restrained by said gears.
Claim 8
Dependent Claim
55 words
The control means with a spring lever as claimed in claim 5, including an adjustment mounting connected with said member, and with said member having adjustment movement in the directions of movement of said end portion for adjustably positioning said restraining positions relative to said lever and thereby vary the restrained positions of said lever.
Claim 9
Dependent Claim
75 words
The control means with a spring lever as claimed in claim 5, wherein said lever is L-shaped and has its comparable upright portion thereof defined by terminating in said handle, a pivot mounting engaged with the comparable horizontal portion of the L-shaped lever, and with the length of said lever along said upright portion thereof being greater than the spacing between said restraining positions on said member, for creating strong spring energy in said lever.
Claim 10
Dependent Claim
48 words
The control means with a spring lever as claimed in claim 7, wherein said member includes two notches for providing said restraining positions, and said member includes a slot extending between said notches for sliding movement and control of said end portion in its movement between said notches.
Claim 11
Dependent Claim
50 words
The control means with a spring lever as claimed in claim 8, wherein said member is a plate and it includes mounting slots extending parallel to the first said slot, and including mounting bolts engaged with said plate and extending through said mounting slots and thereby providing an adjustment mounting.
