Abstract
Abstract A lifting apparatus is mounted directly on a vehicle for elevating relatively heavy loads from a lower level onto the roof of the vehicle. The lifting apparatus includes a hoist mounted on the upper end of a reciprocable support tube telescopically mounted in a receiving tube rigidly secured to the vehicle. The support tube is axially adjustable to vary the effective length thereof above the roof of the vehicle and is rotatable relative to its mounting to swing a lifted load onto the roof of the vehicle for storage during transport.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
251 words
A lifting apparatus in combination with a vehicle body comprising: a mobile body; support means rigidly secured to said mobile body; an elongated, vertically extending tube telescopically received within said support means for reciprocable movement relative thereto; means including a bearing for mounting said tube for rotational movement relative to said support means; a washer keyed to said tube for rotation therewith relative to said support means; said reciprocable tube having a plurality of paired, diametrically opposed openings spaced axially along said tube; a pin insertable into a selected pair of said diametrically opposed openings and having portions engagable with and supported by said washer for securing said tube in any of a plurality of axially adjusted positions corresponding to any one of said plurality of paired diametrically opposed openings, said washer having means to lock said washer to said pin in a horizontal plane for rotation therewith when said pin is inserted into said opposed openings and whereby said washer is freely rotatable with respect to said vertically extending tube when said pin is removed from said opposed openings; a hoist mounted on the upper end of said tube for axial and rotational movement therewith; said hoist comprising a cable wound about a drum and having means on the distal end thereof for engaging a load; and drive means for imparting motion to said cable for raising anD lowering said load engaging end, whereby said bearing supports the combined weight of said vertically extending tube, said load and said hoist.
Claim 2
Dependent Claim
251 words
A lifting apparatus in combination with a vehicle body comprising: a mobile body; support means rigidly secured to said mobile body; an elongated, vertically extending tube telescopically received within said support means for reciprocable movement relative thereto; means including a bearing for mounting said tube for rotational movement relative to said support means; a washer keyed to said tube for rotation therewith relative to said support means; said reciprocable tube having a plurality of paired, diametrically opposed openings spaced axially along said tube; a pin insertable into a selected pair of said diametrically opposed openings and having portions engagable with and supported by said washer for securing said tube in any of a plurality of axially adjusted positions corresponding to any one of said plurality of paired diametrically opposed openings, said washer having means to lock said washer to said pin in a horizontal plane for rotation therewith when said pin is inserted into said opposed openings and whereby said washer is freely rotatable with respect to said vertically extending tube when said pin is removed from said opposed openings; a hoist mounted on the upper end of said tube for axial and rotational movement therewith; said hoist comprising a cable wound about a drum and having means on the distal end thereof for engaging a load; and drive means for imparting motion to said cable for raising anD lowering said load engaging end, whereby said bearing supports the combined weight of said vertically extending tube, said load and said hoist.

Claim 4
Dependent Claim
30 words
The combination of claim 1 including a platform rigidly secured to the upper end of said tube, a bracket secured to said platform, said hoist being mounted on said bracket.
Claim 5
Dependent Claim
69 words
The combination of claim 3 wherein said drive means includes a rotatable shaft supporting said hoist drum and journalled in said bracket; a first gear secured to said shaft; a second gear in meshing engagement with said first gear and rigidly secured to one end of a drive shaft journalled in said bracket; and means connected to th other end of said drive shaft for rotating said drive shaft.
Claim 6
Dependent Claim
84 words
The combination of claim 4 wherein said body has a roof and a floor provided with aligned openings, respectively; said support means comprising a bracket mounted on the outer surface of said roof opening for receiving the upper end of said tubular member, and a plate secured to the outer surface of said floor and having an opening in registry with said floor opening for receiving the lower end of said tubular member; said bearing being secured to said bracket about said tubular member.
Claim 7
Dependent Claim
35 words
The combination of claim 1 wherein said support means comprises at least one tubular member for receiving said tube; and a mounting plate formed integral with said tubular member for attachment to said mobile body.
Claim 8
Dependent Claim
71 words
The combination of claim 6 wherein said body has an exposed outer wall surface and a roof; said plate being rigidly secured to said outer wall surface; said support means further comprising a bracket mounted on said roof and having a portion projecting outwardly beyond said outer wall surface; said projecting portion having an opening for receiving said tubular member; said bearing being secured to said bracket about said tubular member.
Claim 9
Dependent Claim
