Claim 1
Independent Claim
193 words
Fastener means for securing a container provided with bottom corner castings to a lowermost supporting surface, said casting each having a cavity including a side access and a bottom access, said means comprising, a stacker fitting secured to said supporting surface and provided with an upstanding nose portion and a horizontally disposed bore therethrough, said container casting adapted to be positioned upon said supporting surface with said fitting nose portion disposed through said bottom access and within said cavity, said fitting bore axially aligned with said casting side access, a key assembly including a shank and key bar disposed through said side access with said key bar positioned within said fitting bore, vertically expandable means carried by said key bar projecting downwardly from the bottom thereof juxtaposed said casting bottom access and operable upon axial displacement of said key assembly to urge said fitting upwardly while urging said casting downwardly against said supporting surface, said expandable means including means engageable within said casting bottom access to prevent axial displacement of said expandable means during axial displacement of said shank and key bar, and means engaging said shank to axially displace said key assembly.

Fastener means for securing a container provided with bottom corner castings to a lowermost supporting surface, said casting each having a cavity including a side access and a bottom access, said means comprising, a stacker fitting secured to said supporting surface and provided with an upstanding nose portion and a horizontally disposed bore therethrough, said container casting adapted to be positioned upon said supporting surface with said fitting nose portion disposed through said bottom access and within said cavity, said fitting bore axially aligned with said casting side access, a key assembly including a shank and key bar disposed through said side access with said key bar positioned within said fitting bore, vertically expandable means carried by said key bar projecting downwardly from the bottom thereof juxtaposed said casting bottom access and operable upon axial displacement of said key assembly to urge said fitting upwardly while urging said casting downwardly against said supporting surface, said expandable means including means engageable within said casting bottom access to prevent axial displacement of said expandable means during axial displacement of said shank and key bar, and means engaging said shank to axially displace said key assembly.
Claim 3
Dependent Claim
86 words
Fastener means according to claim 1 wherein said stacker fitting includes a vertical sidewall below said nose portion, a lateral lug extending from the lower portion of said sidewall to provide a top shoulder, and said supporting surface includes a top access of a transverse dimension normally less than that of said fitting and lug, whereby, said fitting is secured to said supporting surface by first inserting said lug through said top access and then twisting said fitting to lock said lug beneath said supporting surface.
Claim 4
Dependent Claim
24 words
Fastener means according to claim 2, wherein said fitting is elongated in transverse section through said sidewall and includes a pair of said lugs.
Claim 5
Dependent Claim
30 words
Fastener means according to claim 2, wherein said fitting is provided with a keeper plate surrounding said sidewall and means on said fitting limiting the vertical displacement of said plate.
Claim 6
Dependent Claim
34 words
Fastener means according to claim 1, wherein said fitting nose portion is tapered toward its free end to facilitate alignment thereof with said bottom access when said container is positioned upon said supporting surface.
Claim 7
Dependent Claim
22 words
Fastener means according to claim 1, wherein said key assembly shank is threaded and said displacing means thereon is a threaded nut.
Claim 8
Dependent Claim
26 words
Fastener means according to claim 1, wherein said key assembly shank includes a transverse tapered bore and said displacing means thereon is a tapered wedge bar.
Claim 9
Dependent Claim
62 words
Fastener means according to claim 1, wherein said expandable means includes a sliding wedge lock carried by said key bar, said wedge lock having a top ramp surface, and an inclined cam surface on said key bar engaging said ramp surface, whereby relative movement of said ramp surface and cam surface vertically displaces said wedge lock with respect to said key bar.
Claim 10
Dependent Claim
67 words
Fastener means according to claim 1, wherein said stacker fitting includes a second horizontally disposed bore having its axis normal to said first bore, a second side access to said cavity disposed normal to said first side access, a transverse lock key disposed through one said side access and said second fitting bore, and said key bar disposed through said first bore and over said lock key.
Claim 11
Dependent Claim
62 words
Fastener means according to claim 9, wherein said expandable means includes a sliding wedge lock carried by said key bar, said wedge lock having a top ramp surface, and an inclined cam surface on said key bar engaging said ramp surface, whereby relative movement of said ramp surface and cam surface vertically displace said wedge lock with respect to said key bar.
Claim 12
Dependent Claim
26 words
Fastener means according to claim 10, wherein said wedge lock is provided with a notch on its lower edge and said notch straddles said lock key.
Claim 13
Dependent Claim
