Abstract
Abstract An engine hoist and rebuild stand assembly is provided including an upright standard and an inclined boom removably supported from the upper end of the standard. The boom includes a lengthwise extendable load lifting end provided with a guide pulley over which an elongated flexible tension member may be passed and the end of the tension member which passes over the guide pulley is operatively connected to winding and unwinding structure carried by the non-extendable end of the boom. Further, the standard includes a horizontal transvers base outwardly from which a pair of generally parallel leg assemblies project in generally the same direction from which the extendable end of the boom projects from the standard and a mid-height portion of the standard includes a mount supported therefrom for selectively angular displacement about a horizontal axis generally paralleling the leg assemblies and from which mount the bell housing end of an engine may be securely mounted.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
225 words
A mobile engine hoist and rebuild stand assembly, said assembly including an upright standard having upper and lower ends, base means carried by said lower end for support of said standard from a support surface disposed therebeneath, an elongated boom having base and free end portions and removably supported from the upper end of said standard with at least said free end portion projecting outwardly of one side of said standard, said free end portion being supported from said base end portion for adjusted longitudinal extension and retraction relative to said base end portion, an elongated, flexible load lifting tension member having first and second ends and a mid-portion disposed between and connecting said first and second ends, winding and unwinding means mounted on said boom base end portion and with which said first end is operatively connected for winding thereon and unwinding therefrom, guide means carried by said free end portion guidingly engaging said mid-portion and allowing said second end to depend downwardly therefrom, means carried by said second end portion for engagement with a load to be lifted, said base end portion of said boom projecting outwardly from a second side of said standard opposite said one side, and inclined brace means releasably connected between said standard at a point thereon below said boom and the terminal end of said base end portion.
Claim 2
Dependent Claim
225 words
A mobile engine hoist and rebuild stand assembly, said assembly including an upright standard having upper and lower ends, base means carried by said lower end for support of said standard from a support surface disposed therebeneath, an elongated boom having base and free end portions and removably supported from the upper end of said standard with at least said free end portion projecting outwardly of one side of said standard, said free end portion being supported from said base end portion for adjusted longitudinal extension and retraction relative to said base end portion, an elongated, flexible load lifting tension member having first and second ends and a mid-portion disposed between and connecting said first and second ends, winding and unwinding means mounted on said boom base end portion and with which said first end is operatively connected for winding thereon and unwinding therefrom, guide means carried by said free end portion guidingly engaging said mid-portion and allowing said second end to depend downwardly therefrom, means carried by said second end portion for engagement with a load to be lifted, said base end portion of said boom projecting outwardly from a second side of said standard opposite said one side, and inclined brace means releasably connected between said standard at a point thereon below said boom and the terminal end of said base end portion.
Claim 3
Dependent Claim
105 words
The assembly of claim 1 wherein said one side of said standard includes engine block mounting means thereon spaced below said boom and against which the bell housing end of an automotive engine block may be biased for bolting thereto when said free end portion of said boom is retracted relative to said base end portion and said engine block is elevated by said tension member to a position closely spaced below said boom, said mounting means being supported from said one side of said standard for adjusted angular displacement relative to said standard about a horizontal axis disposed generally normal to said one side.
Claim 4
Dependent Claim
34 words
The assembly of claim 1 wherein said base end portion of said boom includes an intermediate length portion having support shank means depending therefrom removably telescopingly engaged with the upper end of said standard.
Claim 5
Dependent Claim
16 words
The assembly of claim 3 wherein said boom is inclined with said free end disposed uppermost.
Claim 6
Dependent Claim
112 words
The assembly of claim 1 wherein said base means includes an elongated horizontal transverse base member from which the lower end of said standard is supported intermediate the opposite ends of said transverse base member, the opposite end portions of said base member including elongated laterally outwardly projecting leg members having inner ends mounted from said base member and outer end portions extending outward of the same side of said base member in the same general direction in which said one side of said standard faces, the opposite ends of said base member and the outer end portions of said leg members including support members mounted therefrom for support from said surface.
Claim 7
Dependent Claim
12 words
The assembly of claim 5 wherein said support members comprise support wheels.
Claim 8
Dependent Claim
23 words
The assembly of claim 5 wherein said outer end portions are supported from said inner ends for adjusted extension and retraction relative thereto.
Claim 9
Dependent Claim
12 words
The assembly of claim 7 wherein said support members comprise support wheels.
Claim 10
Dependent Claim
104 words
The assembly of claim 5 wherein said one side of said standard includes engine block mounting means thereon spaced below said boom and against which the bell housing end of an automobile engine block may be biased for bolting thereto when said free end portion of said boom is retracted relative to said base end portion and said engine block is elevated by said tension member to a position closely spaced below said boom, said mounting means being supported from said one side of said standard for adjusted angular displacement relative to said standard about a horizontal axis generally normal to said one side.
