Abstract
Abstract A vehicle including both a flanged wheel suspension system and a rubber wheel suspension system, and including means for converting from flanged wheel operation to rubber tire operation. The means includes a support member to one end of which the rubber tire wheel is rotatably mounted while the other end is pivotally mounted to the vehicle. An arm extends generally perpendicular to the supporting member and is fixedly connected thereto adjacent the pivotal connection of said supporting member to pivot with the support member and this arm is capable of being locked in two positions by cooperating with a pin which engages the sides of the arm. In first locking position the arm engages the rubber tire with the ground while in the second locking position the rubber tire is disposed above ground level whence the vehicle rests upon flanged wheels. A spring connected between the wheel and the vehicle helps to urge the wheel upward from the ground engaging position and a handle is attached to the support member near to the rubber tire for lifting the tire from a ground engaging position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
Apparatus for suspending a vehicle wheel at plural positions comprising a support member pivotally connected at a first end to said vehicle and including mounting means disposed adjacent said second end for rotatably mounting said wheel, an arm extending at an angle to the longitudinal axis of said member, said arm being fixedly attached to said first end of said member adjacent the pivot axis of said support member so as to pivot with said support member, and a means for locking said arm in either a first position in which said wheel engages the ground or a second position in which said wheel does not contact the ground.
Claim 2
Dependent Claim
109 words
Apparatus for suspending a vehicle wheel at plural positions comprising a support member pivotally connected at a first end to said vehicle and including mounting means disposed adjacent said second end for rotatably mounting said wheel, an arm extending at an angle to the longitudinal axis of said member, said arm being fixedly attached to said first end of said member adjacent the pivot axis of said support member so as to pivot with said support member, and a means for locking said arm in either a first position in which said wheel engages the ground or a second position in which said wheel does not contact the ground.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 further including spring means connected between said support member and said vehicle for urging said wheel away from the ground when said arm is in its second position.
Claim 4
Dependent Claim
24 words
The apparatus of claim 1 further including a handle attached to said support member near said mounting means for helping to raise said wheel.
Claim 5
Dependent Claim
178 words
A vehicle which is capable of running on rails or a smooth roadway comprising a plurality of flanged wheels rotatably mounted to said vehicle and so disposed about said vehicle for running upon rails, a plurality of wheels which are adapted to support said vehicle for running upon said smooth roadway when placed into engagement therewith and means for moving said roadway wheels to and from positions of engagement with said roadway, said moving means including for each wheel a support member pivotally connected at a first end to said vehicle and including mounting means disposed adjacent said second end for rotatably mounting said wheel, an arm extending at an angle to the longitudinal axis of said member, said arm being fixedly attached to said first end of said member adjacent the pivot axis of said support member so as to pivot with said support member, and a means for locking said arm in either a first position in which said wheel engages the ground or a second position in which said wheel does not contact the ground.
Claim 6
Dependent Claim
178 words
A vehicle which is capable of running on rails or a smooth roadway comprising a plurality of flanged wheels rotatably mounted to said vehicle and so disposed about said vehicle for running upon rails, a plurality of wheels which are adapted to support said vehicle for running upon said smooth roadway when placed into engagement therewith and means for moving said roadway wheels to and from positions of engagement with said roadway, said moving means including for each wheel a support member pivotally connected at a first end to said vehicle and including mounting means disposed adjacent said second end for rotatably mounting said wheel, an arm extending at an angle to the longitudinal axis of said member, said arm being fixedly attached to said first end of said member adjacent the pivot axis of said support member so as to pivot with said support member, and a means for locking said arm in either a first position in which said wheel engages the ground or a second position in which said wheel does not contact the ground.
Claim 7
Dependent Claim
33 words
The apparatus of claim 4 further including spring means connected between said support member and said vehicle for urging said wheel away from the ground when said arm is in its second position.
Claim 8
Dependent Claim
24 words
The apparatus of claim 4 further including a handle attached to said support member near said mounting means for helping to raise said wheel.
Claim 9
Dependent Claim
182 words
In a vehicle of the type having a frame and a set of wheels mounted so as to be adjustable between an upper non-operating position and a lower operating position with respect to the fraMe, the improved mounting for a wheel comprising: a support arm having a first end pivotally connected to the frame for swinging movement between upper and lower positions in a vertical plane about a horizontal axis, said support arm carrying at least one of said wheels at a location outwardly of said axis, another arm extending at an angle to the longitudinal axis of said support arm, adjacent the pivot axis of said support arm, said other arm having an outer end and having an inner end fixed to said support arm at the location of said axis so that upon swinging movement of said support arm said other arm also swings about said axis; and locking means carried by said vehicle frame for engaging the outer end portion of said other arm to lock said arm in either the upper or lower position of said support arm.
Claim 10
Dependent Claim
182 words
In a vehicle of the type having a frame and a set of wheels mounted so as to be adjustable between an upper non-operating position and a lower operating position with respect to the fraMe, the improved mounting for a wheel comprising: a support arm having a first end pivotally connected to the frame for swinging movement between upper and lower positions in a vertical plane about a horizontal axis, said support arm carrying at least one of said wheels at a location outwardly of said axis, another arm extending at an angle to the longitudinal axis of said support arm, adjacent the pivot axis of said support arm, said other arm having an outer end and having an inner end fixed to said support arm at the location of said axis so that upon swinging movement of said support arm said other arm also swings about said axis; and locking means carried by said vehicle frame for engaging the outer end portion of said other arm to lock said arm in either the upper or lower position of said support arm.
Claim 11
Dependent Claim
52 words
Apparatus as in claim 7 wherein said support arm extends generally longitudinally of said vehicle and said other arm extends generally upwardly and wherein said locking means includes a locking element which is engageable with opposite surfaces of the outer end portion of said other arm in said upper and lower positions.
Claim 12
Dependent Claim
52 words
Apparatus as in claim 8 wherein said locking element is mounted for generally vertical movement relative to said vehicle frame so as to be movable out of the path of said other arm during swinging movement thereof and movable into said path in either said upper or lower positions of said arms.
