Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
213 words
A snow removal machine, comprising, a. a wheeled chassis having a prime mover and a control station, b. a snow removal frame on the chassis including a snow gathering housing, c. snow removal blades rotatable in the housing, d. an upwardly directed snow discharge chute rotatable on the housing about an upright axis, e. a deflector pivotally mounted on the upper end of the chute for movement between an upper position and a lower position and means for normally urging said deflector toward said upper position, and f. means for pivotally adjusting the deflector from the control station, including F-1. a support bracket having a cable guide, F-2. means mounting the bracket with the cable guide in line with the axis of rotation of the chute, F-3. a single cable having one end secured to the deflector for moving said deflector toward said lower position, and (f-4) A roatable shaft mounted on the bracket and having an end portion positoned above the cable guide and being connected to the other end of the cable, an intermediate portion of the cable bearing on the cable guide whereby rotation of the end portion of the shaft advances the cable past the guide and about the end portion to move the deflector toward said lower position.
Claim 2
Dependent Claim
213 words
A snow removal machine, comprising, a. a wheeled chassis having a prime mover and a control station, b. a snow removal frame on the chassis including a snow gathering housing, c. snow removal blades rotatable in the housing, d. an upwardly directed snow discharge chute rotatable on the housing about an upright axis, e. a deflector pivotally mounted on the upper end of the chute for movement between an upper position and a lower position and means for normally urging said deflector toward said upper position, and f. means for pivotally adjusting the deflector from the control station, including F-1. a support bracket having a cable guide, F-2. means mounting the bracket with the cable guide in line with the axis of rotation of the chute, F-3. a single cable having one end secured to the deflector for moving said deflector toward said lower position, and (f-4) A roatable shaft mounted on the bracket and having an end portion positoned above the cable guide and being connected to the other end of the cable, an intermediate portion of the cable bearing on the cable guide whereby rotation of the end portion of the shaft advances the cable past the guide and about the end portion to move the deflector toward said lower position.
Claim 3
Dependent Claim
39 words
A snow removal machine as defined in claim 1, including a bearing bracket rotatably supporting one shaft end portion, and means mounting the bearing bracket for rotation on the guide bracket about the axis of rotation of the chute.
Claim 4
Dependent Claim
40 words
A snow removal mahcine as defined in claim 1, including a bearing bracket rotatably supporting one shaft end portion, and means mounting the bearing bracket for pivotal movement on the guide bracket about an axis transverse to the shaft axis.
Claim 5
Dependent Claim
61 words
A snow removal machine as defined in claim 1, including a mounting bracket supported on the guide bracket for rotation about the axis of rotation of the chute, and a bearing bracket rotatably supporting one shaft end portion and pivotally mounted on the mounting bracket for movement about an axis transverse to the shaft axis and transverse to the chute axis.
Claim 6
Dependent Claim
56 words
A snow removal machine as defined in claim 1, in which the cable guide bracket is mounted on the chassis, and a bearing bracket is provided rotatably supporting the shaft end portion, and means are provided for mounting the bearing bracket for pivotal movement on the guide bracket about an axis transverse to the shaft axis.
Claim 7
Dependent Claim
36 words
A snow removal machine as specified in claim 1 in which means are provided for retaining the end portion of the rotatable shaft in angularly adjusted positions so as to vary the positioning of the deflector.
Claim 8
Dependent Claim
142 words
A snow removal machine, comprising, A. a wheeled chassis having a prime mover and a control station, b. a snow removal frame on the chassis including a snow gathering housing, c. snow removal blades rotatable in the housing, d. an upwardly directed snow discharge chute rotatable on the housing about an upright axis, e. a deflector pivotally mounted on the upper end of the chute, and f. means for pivotally adjusting the deflector from the control station, including f-1. a support brAcket, f-2. means mounting the support bracket adjacent the axis of rotation of the chute, F-3. a cable secured to the deflector, f-4. an adjustable shaft mounted on the support bracket, and F-5. a reel on the end of the shaft adjacent the bracket connected to the cable and having a periphery aligned with the axis of rotation of the chute.
Claim 9
Dependent Claim
142 words
A snow removal machine, comprising, A. a wheeled chassis having a prime mover and a control station, b. a snow removal frame on the chassis including a snow gathering housing, c. snow removal blades rotatable in the housing, d. an upwardly directed snow discharge chute rotatable on the housing about an upright axis, e. a deflector pivotally mounted on the upper end of the chute, and f. means for pivotally adjusting the deflector from the control station, including f-1. a support brAcket, f-2. means mounting the support bracket adjacent the axis of rotation of the chute, F-3. a cable secured to the deflector, f-4. an adjustable shaft mounted on the support bracket, and F-5. a reel on the end of the shaft adjacent the bracket connected to the cable and having a periphery aligned with the axis of rotation of the chute.
Claim 10
Dependent Claim
20 words
