Abstract

Abstract Relatively movable load-carrying members connected to be maintained in predetermined relation with hydraulic means for producing relative movement, to serve for example as a hi-lift, the device being of a character to be mounted on a fixed or other base such as a vehicle, and also designed to be tilted to dump a load carried thereby.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 217 words
A hi-lift or dump unit for mounting on a vehicle chassis comprising a base frame, means for connecting said base frame to the chassis of the vehicle, a hi-lift frame movably connected to said base frame by spaced pairs of hi-lift arms, a dump frame having a swingable connection with said hi-lift frame adjacent one end thereof, lock means slidably mounted on said dump frame, lock-receiving means carried by said hi-lift frame and adapted to receive said lock means when the same is extended, lever means for extending and retracting said lock means to eNgage and disengage said receiving means, said lock means being located in spaced relation to the swingable connection between said hi-lift frame and said dump frame, an upright support mounted on the end of said dump frame remote from said swingable connection, fluid cylinder means connecting said base frame and said upright support, and a body mounted on said dump frame, whereby when said lock means is disposed within said receiving means the dump frame and the hi-lift frame are locked together and operation of said fluid cylinder means will raise the body in a generally horizontal plane, and when said lock means is retracted from engagement with said receiving means, one end of the body will be raised and cause tilting thereof.
Claim 2
Dependent Claim 217 words
A hi-lift or dump unit for mounting on a vehicle chassis comprising a base frame, means for connecting said base frame to the chassis of the vehicle, a hi-lift frame movably connected to said base frame by spaced pairs of hi-lift arms, a dump frame having a swingable connection with said hi-lift frame adjacent one end thereof, lock means slidably mounted on said dump frame, lock-receiving means carried by said hi-lift frame and adapted to receive said lock means when the same is extended, lever means for extending and retracting said lock means to eNgage and disengage said receiving means, said lock means being located in spaced relation to the swingable connection between said hi-lift frame and said dump frame, an upright support mounted on the end of said dump frame remote from said swingable connection, fluid cylinder means connecting said base frame and said upright support, and a body mounted on said dump frame, whereby when said lock means is disposed within said receiving means the dump frame and the hi-lift frame are locked together and operation of said fluid cylinder means will raise the body in a generally horizontal plane, and when said lock means is retracted from engagement with said receiving means, one end of the body will be raised and cause tilting thereof.
Claim 3
Dependent Claim 98 words
A hi-lift or dump unit comprising a first frame, a second frame movably mounted on said first frame, a third frame having a swingable connection with said second frame adjacent one end thereof, lock means spaced from said swingable connection for selectively connecting said second and third frames, and means for raising one end of said third frame while maintaining the same generally parallel to said first frame when said second frame and said third frame are locked together, and swinging said third frame about said swingable connection when said second frame and said third frame are unlocked.
Claim 4
Dependent Claim 98 words
A hi-lift or dump unit comprising a first frame, a second frame movably mounted on said first frame, a third frame having a swingable connection with said second frame adjacent one end thereof, lock means spaced from said swingable connection for selectively connecting said second and third frames, and means for raising one end of said third frame while maintaining the same generally parallel to said first frame when said second frame and said third frame are locked together, and swinging said third frame about said swingable connection when said second frame and said third frame are unlocked.
Claim 5
Dependent Claim 24 words
The structure of claim 2 in which the movable mounting between said first frame and said second frame includes spaced pairs of hi-lift arms.
Claim 6
Dependent Claim 71 words
The structure of claim 2 in which said lock means for selectively connecting said second and third frames includes retaining means carried by one of said second and third frames, receiving means carried by the other of said frames and axially alignable with said retaining means, pin means slidably mounted in said retaining means, and means for moving a portion of said pin means axially into engagement with said receiving means.
Claim 7
Dependent Claim 15 words
The structure of claim 4 including means for securing said pin means in adjusted position.
Claim 8
Dependent Claim 21 words
The structure of claim 2 including mounting means for mounting said hi-lift or dump unit on the chassis of a vehicle.
Claim 9
Dependent Claim 45 words
The structure of claim 2 in which said means for raising one end of said third frame includes an upright support on said third frame, and fluid-cylinder means connecting said first frame and said upright support to provide a lifting force for said third frame.
