The prior art teaches rudimentary "gooseneck-type roadway-chassis" advocated for overlyingly attachably removably accommodating, and directionally longitudinally between its rear-end and an elevated goosenecked front-end, a single only cargo-container of encountered-length. Herein disclosed is a novel concept for improved "gooseneck-type roadway-chassis" that is alternatively adaptable for removable attachment thereatop either: a single extended-overall-length cargo-container underlyingly centrally longitudinally provided with a partial-tunnel channel for the chassis forward gooseneck; or two longitudinally consecutive short-length cargo-containers devoid of underlying channel. For the herein disclosed invention: the chassis gooseneck elevated frontal-end is dually provided in transverse separation with internal and longitudinally-retractable attachment pins and also with topical twistlocks; and immediately rearwardly of the chassis gooseneck portion also additionally provided with reciprocatably-elevational and transversely separated twistlocks for removably thereatop attaching a serially forward short-length cargo-container.

BACKGROUND OF THE INVENTION 
Drawing FIGS. 1 and 2 depict a typical prior art structure (e.g. 10) for 
"gooseneck-type roadway-chassis" adapted to overlyingly removably attach a 
single cargo-container (e.g. 100 of FIGS. 3A & 3B; 200 of FIG. 3C; etc.). 
Such typical "gooseneck-type roadway-chassis" (10) comprises a pair of 
directionally longitudinally extending parallel rails (11, 12) maintained 
(e.g. 10C, 10P) in flanking parallel relationship to an intervening 
vertical-plane (10V). Such parallel rails (11, 12) have a major 
rearward-length (11A, 12A) rearwardly terminating at chassis rear-end 13, 
and a minor and elevated "gooseneck" forward-length (11B, 12B) forwardly 
terminating at chassis front-end 14 and having thereat a directionally 
transversely extending horizontal structural member 15. Reference 
character 10C refers to a horizontal connector between members 11B and 12B 
and centrally-provided along vertical-plane 10V with a location 10D to 
accommodate a towing-tractor "5th-wheel-pin coupler" (traditional, and not 
shown). Reference character 10B refers to rails-depending journal means 
for a horizontal axle (10A) for chassis wheels (10W) that are 
conventionally downwardly-impingeable upon a horizontal roadway-substrate 
(9). Reference characters 10E and 10F refer gooseneck-depending (e.g. from 
11B and 12B), and upwardly-retractable conventional frontal-props that are 
selectively downwardly impingeable upon a such underlying substrate (9). 
Internally within front-end connector member 15, and flanking 
vertical-plane 10V, are directionally longitudinally movable pins (15A, 
15B) to removably securely accommodate corner-castings (99) frontal 
horizontal-holes (107A, 107B, respectively) of an overlyable 
extended-overall-length (EOL) cargo-container (e.g. 100 of FIGS. 3A and 
3B) having an underlying longitudinal partial-tunnel-like channel (108). 
And in the foregoing regard, the reader's attention is called to prior art 
drawing FIGS. 3A and 3B for typical prior art cargo-container (100) of 
extended overall-length (EOL) and of finite-height (FH), and also to prior 
art drawing FIG. 3C for typical prior art cargo-container (200) of 
"half-overall-length" (HOL) and of arrested-height (AFH) and wherein: 
A such conventional extended-overall-length (EOL) and generous 
finite-height (FH) prior art cargo-container (100) comprises: horizontal 
and opposed upper-panel 101 and lower-panel 102; upright sideward panels 
(103, 104) connecting panels 101 and 102; upright rear-panel 105 and 
upright front-panel 106 (together connecting panels 101, 102, 103, and 
104). Located at the four-corners of lower-panel 102 are such 
corner-castings 99 (as in U.S. Pat. Nos. 3,486,787 and 4,459,072 for 
twistlocks 13M herein), and respectively provided at front-panel 106 with 
such horizontal-holes 107A and 107B. Lowerpanel 102 along vertical-plane 
10V, commencing from front-panel 106, is provided with a partial-tunnel 
channel 108 for downwardly flankingly embracing "gooseneck" frontal-rails 
portion (11B, 12B). But for a conventional halfwise-extended-length (HOL) 
and normally of less than 20-feet-length, and of arrested-height AFH, 
prior art cargo-container 200 generally comprises: horizontal and opposed 
upper-panel 201 and lower-panel 202; upright sideward panels (203, 204) 
connecting panels 201 and 202; and upright rear-panel 205 and upright 
front-panel (connecting panels 201-204). Located at the four-corners of 
lower-panel 202 are such aforedescribed corner-castings (99). 
And with further regard to the prior art mentioned in the immediately 
preceeding paragraphs: the such prior art chassis (10) and atop rails' 
rearward-lengths 11A and 12A further comprises there atop a plurality of 
attached, directionally transversely extending, and longitudinally 
consecutively-spaced bolsters (13) including: a rearwardmost bolster 13A, 
a forwardmost bolster 13E, and longitudinally consecutively therebetween 
intermediate bolsters 13B-13D. Each of the said bolsters 13, in outwardly 
flanking relationship to said rails' parallel rearward-lengths 11A and 
11B, is conventionally provided theratop with such conventional twistlocks 
13M alluded to hereabove. 
Accordingly, in view of the disclosures made in the five immediately 
preceding paragraphs, and in further regard to prior art drawing FIG. 1, 
and in further regard to the removably attached (13M, 99, 15, and 107) 
phantom-lines) for such overlying cargo-containers (100, 200): 
Every such extended-overall-length cargo-container (100) conventionally at 
such corner-castings frontal horizontal-holes (107) is removably attached 
with such horizontally-reciprocatable attachment-pins (15), and has its 
underlying partial-tunnel channel (108) downwardly flanking rails' 
elevated "gooseneck" forward-length 11B-12B (whereby such cargo-container 
height FH meets highway Regulations; and every such 
extended-overall-length (EOL) cargo-container has its rear-panel (105) 
corner-castings (99) appropriately removably connected to bolster 
twistlocks (13M). In the latter regard: 105A might refer to a rear-panel 
of a 44-feet-length cargo-container at rearward-most bolster 13A; 105B 
might refer to a rear-panel of a 42-feet-length cargo-container (100) at 
bolster 13B; and 105C might refer to the rear-panel of a 40-feet-length 
cargo-container attached at bolster 13C; and also in the latter regard a 
such abbreviated-overall-length cargo-container (200), and which 
traditionally lacks a such underlying partial-tunnel channel (108): 
conventionally has its front-end (206) and its rear-end (205) 
lower-corner-castings (99) removably relegatably attached to the 
twistlocks (13M) on bolsters 13D and 13E which are traditionally relegated 
to the chassis rails' rearward-lengths (11A, 12A). 
Thus, it will be appreciated from the foregoing description of the prior 
art, that such "gooseneck-type roadway-chassis" (e.g. 10) of the prior art 
are deficient in that, though their overall longitudinal-length (13-14) 
might theoretically accommodate therealong, two half-length 
cargo-containers (200), the prior art makes no structural provision to do 
so and within the heightwise (e.g. AFH at goosenecked rails 11B & 12B) 
requirements of Governmental Highway Regulations. 
General Objectives of the Present Invention 
In view of the foregoing discussion of prior art disclosures, it is 
accordingly the general objective of the present invention to provide 
improved "goosneck-type roadway-chassis" that is alternatively adaptable 
to attachably accommodate thereatop: either, two consecutive 
arrested-length (200) cargo-containers, or, a single elongated-length 
(100) cargo-container, and in either situation in conformity with 
roadway-height restrictions of Highway Regulations. 
General Statement of the Invention 
With the above general objectives in view, and together with other 
ancillary and related objectives which will become more apparent as this 
description proceeds, the novel improved "gooseneck-type roadway-chassis" 
concept of the present invention generally comprises: a pair of horizontal 
elongate rails which at their forward-ends are commonly perpendicularly 
provided with a frontal-member, such parallel rails including major 
rearward-lengths and minor and elevationally higher (gooseneck) 
forward-lengths, the rails' rearward-lengths being commonly 
perpendicularly provided thereatop with a consecutive plurality of 
horizontal bolsters endwardly provided with twistlocks for removably 
attaching rearward corner-castings of an overlying cargo-container, and 
with further regard for removably frontally and alternatively attaching 
differing cargo-containers, the chassis frontal-member is dually provided 
with alternately employable retractable attachment-pins and thereabove 
with such twistlocks, and in the latter regard, the rails' 
rearward-lengths are additionally forwardly provided with a secondary 
horizontal bolster having vertically reciprocatably movable endwise 
twistlocks.

DETAILED DESCRIPTION OF THE DRAWING 
The representative embodiment (10M) of the improved "gooseneck-type 
roadway-chassis" of drawing FIGS. 4-7 includes all the structural elements 
of the prior art "gooseneck-type roadway-chassis" (10) of drawing FIGS. 1 
and 2, but structurally differs from (10) in the following respects for 
improved embodiment 10M: 
(a) the rails' forward-length terminal frontal-member 15 is additionally 
topically provided (in flanking relationship to vertical central-plane 10V 
and in overlying relationship to the retractable attachment-pins 15A & 
15B) with such prior art twistlocks 13M (but for FIGS. 4-7 distinguishable 
denominated as 13MN); and 
(b) the rails' rearward-lengths 11A & 12A (located below rails' 
forward-lengths 11B and 12B) is thereatop provided with a directionally 
transversely and horizontally extending secondary-bolster 13F (akin to 
primary prior art bolsters 13A-13E), and which secondary-bolster 13F is 
endwardly provided with vertically reciprocatable members 13G and 
topically therefrom with such prior art twistlocks 13M (but for FIGS. 4-7 
denominated as 13MP). In the latter regard, such vertically reciprocatable 
endwise collars 13G (which surround endwise portions of secondary-bolster 
13F), might have directionally-longitudinal holes (below attachment-pins 
15A & 15B) that respectively accommodate removable anchoring-pins 13T. 
Thus, such secondary-bolster twistlocks 13MP have selectable elevations 
(13T) both below, and co-planar with, rails' gooseneck frontal-member 
endward twistlocks (13MN). 
Accordingly, in view of the above structural modifications included within 
such improved "gooseneck-type roadway-chassis" (10M) and now with especial 
reference to drawing FIGS. 4-7, such improved "gooseneck-type 
roadway-chassis" representative embodiment (10M) might be laudatorily 
termed ANYSIZER because: 
(i) inasmuch as the FIGS. 1 and 2 elements 13A-13E and endward twistlocks 
13M therefor, and frontal-member (15) retractable attachment-pins 15A and 
15B are retained: the FIGS. 4-7 improved representative embodiment (10M) 
retains the overlyingly removably-attachable capabilities for 
cargo-container embodiments 100 and 200, as alluded to in prior art 
drawing FIG. 1; but also 
(ii) in view of the FIGS. 4-7 additional structural elements 13M at 
secondary-bolster 13F, and such secondary-bolster 13F having endwise 
twistlocks (13MP) of controllable elevation (e.g. 13G, 13T) selectively 
below and co-planar with gooseneck frontal-member twistlocks (13MN): the 
FIGS. 4-7 improved representative embodiment (10M) is additionally 
alternatively adapted to overlyingly removably-attachably accommodate two 
longitudinally serial half-overall-length cargo-containers (e.g. 200 of 
FIG. 3C) having arrested-finite-height (AFH) and in 
roadway-chassis-attached heightwise conformity with roadway-vehicular 
conformity heightwise Highway Regulations. 
From the foregoing, the construction and operation of the improved 
"gooseneck-type roadway-chassis" concept of the present invention will be 
readily understood and further explanation is believed to be unnecessary. 
However, since numerous modifications and changes will readily occur to 
those skilled in the art, it is not desired to limit the invention to the 
exact construction shown and described, and accordingly, all suitable 
modifications and equivalents may be resorted to, falling within the scope 
of the appended claims.
