Abstract
Abstract A drum tie-down apparatus for securing drum-like containers in an upright position to a floor or platform of a transportation vehicle having spaced apart cargo tie-down points. The apparatus comprises a pair of cylindrical, hollow tube segments horizontally oriented and engageable with a drum lid adjacent opposite rim edges, flexible strap segments for connecting upper and lower central portions of the tube segments together across the drum lid and a pair of elongated flexible tie-down segments, one extending horizontally through each of the tube segments, the ends thereof being attached to said spaced apart tie-down points such that end portions of the pair of tie-down segments extend downwardly and radially outwardly from the tube segments to the tie-down points.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
A drum tie-down apparatus for securing drum-like containers in an upright position to a floor or platform of a transportation vehicle having spaced-apart cargo tie-down points, comprising: first and second spaced apart hollow tube segments, whose longitudinal axes are horizontally oriented, engageable with a drum lid adjacent to opposite rim edges; flexible strap segment means for connecting upper and lower central portions of said tube segments together across the drum lid; and a pair of elongated flexible tie-down segments, each extending horizontally through a respective tube segment and having means for attaching the ends thereof to said spaced apart tie-down points such that end portions of the pair of tie-down segments extend downwardly and radially outwardly from the tube segments to the tie-down points.
Claim 2
Dependent Claim
124 words
A drum tie-down apparatus for securing drum-like containers in an upright position to a floor or platform of a transportation vehicle having spaced-apart cargo tie-down points, comprising: first and second spaced apart hollow tube segments, whose longitudinal axes are horizontally oriented, engageable with a drum lid adjacent to opposite rim edges; flexible strap segment means for connecting upper and lower central portions of said tube segments together across the drum lid; and a pair of elongated flexible tie-down segments, each extending horizontally through a respective tube segment and having means for attaching the ends thereof to said spaced apart tie-down points such that end portions of the pair of tie-down segments extend downwardly and radially outwardly from the tube segments to the tie-down points.
Claim 3
Dependent Claim
26 words
A drum tie-down apparatus as set forth in claim 1 wherein the flexible strap segment means is adjustable in length to accommodate containers of different diameters.
Claim 4
Dependent Claim
58 words
A drum tie-down apparatus as set forth in claim 2 wherein the flexible strap segment means comprises at least one chain member and each tube segment is provided with aperture means to enable the upper portions of the tube segments to be adjustably connected together and the lower portions of the tube segments to be adjustably connected together.
Claim 5
Dependent Claim
121 words
A drum tie-down apparatus as set forth in claim 3 wherein said flexible strap segment means comprises first and second chain members, said aperture means comprising an eye-slot aperture in the upper portion of the first tube segment and a like eye-slot aperture in the lower portion of the second tube segment, the first chain member having one end rigidly secured to an upper portion of the second tube segment, with the opposite end being adjustably connectible to the eye-slot aperture of the first tube segment and the second chain member having one end rigidly secure to a lower portion of the first tube segment, with the opposite end being adjustably connectible to the eye-slot aperture of the second tube segment.
Claim 6
Dependent Claim
74 words
A drum tie-down apparatus as set forth in claim 4 wherein the tube segments are of rectangular cross section and wherein a slot portion of the eye-slot aperture of each tube segment extends into an inner surface of its respective tube segment which faces a center portion of the drum lid when in securing position in order to permit direct contact of the lower surfaces of both tube segments to the drum lid surface.
Claim 7
Dependent Claim
90 words
A drum tie-down apparatus as set forth in claim 1 wherein the tube segments are rectangular in cross sectional shape and each tube segment being provided with an eye-slot aperture in both upper and lower surfaces thereof, each eye-slot aperture having a slot which extends toward the center portion of the drum lid when in securing position and whereby said flexible strap segment means comprises at least one chain segment connectible between the upper eye-slot apertures of the tube segments and between the lower eye-slot apertures of the tube segments.
Claim 8
Dependent Claim
101 words
A drum tie-down apparatus as set forth in claim 1 wherein the tube segments are rectangular in cross sectional shape and wherein each tube segment is provided with upper and lower eye-slot apertures therein, each eye-slot aperture having a slot which extends toward the center portion of the drum lid when in securing position and wherein the flexible strap segment means comprises a chain segment connectible from the upper eye-slot of the first tube segment, to the upper eye-slot of the second tube segment and out of the lower eye-slot thereof back to the lower eye-slot of the first tube segment.
Claim 9
Dependent Claim
19 words
A drum tie-down apparatus as set forth in claim 1 wherein the flexible tie-down segments are adjustable in length.
Claim 10
Dependent Claim
30 words
A drum tie-down apparatus as set forth in claim 1 wherein the flexible tie-down segments are each provided with means for tensioning its respective tie-down segment when in securing position.
Claim 11
Dependent Claim
17 words
A drum tie-down apparatus as set forth in claim 1 wherein the tie-down segments are chain members.
