Abstract
ABSTRACT OF THE DISCLOSURE
A cargo restraining device suitable for restraining barrel-shaped containers or drums is disclosed, which includes a plat-form, which is spaced from the underlying supporting surface or floor, by horizontal supporting members which extend the length of at least the flat portion of the platform, so as to provide a raised deck for the containers. At one end of the platform, an upright or vertical frame is connected to the supporting mem-bers, to prevent the containers from falling off the platform.
The other end of the platform can be rounded over to define a snub-nose; or alternatively the other ends of the horizontal supporting members can project beyond the platform (which is otherwise flat) and be rounded into snub-nosed portions. In con-sequence, should the drums shift or move, whereby damage might ordinarily occur, the chimes or rims of the drums tend to flow around the snub-nose (or snub-noses if defined at the supporting members) without any significant damage. Thus, the containers, instead of falling off when moved, gently slide about and off the snub-nosed portion or portions; and no abrupt discontinuous edges are encountered. At both ends of the horizontal support members, floor piercing members are provided, which are normally oriented to the floor piercing position, and firmly hold the platform in place. A strap may be placed around the containers, and secured at the ends to the upright frame, to further restrain movement of the drums on the platform.

Description
iK-613 - ll ~ 4(e)~2) ~2 27089 TITLE: DRUM RESTRAINING DEVI~E
INVENTORS: James Van Gompel and Jerry A. Hall Specification ! Background of the Invention . _ .
This invention relates to a cargo restraining device and, in particular~ to a device for storing and restraining barrel-shaped containers such as drums, to prevent damage during trans-portation thereof.
Prior Art In order to prevent damage during transport to containers for explosive or hazardous materials, such as barrel-shaped con-tainers or drums containing corrosive, volatile, or explosive liquids, such containers have in the past been braced to prevent movement of same. Where such containers ara transported via railroad flat cars or truck trailers, procedures for installing such bracing commonly involve the use of one or more bulkhead boards which wedge t~e containers -- with the assistance of ten~
sioned steel strapping. Such procedures, however, are ~ery ~ime-consuming and costly to implement. Irrespective of such laborious efforts, movement of the load tends to accur, and i damage ensues, leakage o~ the hazardous liquid contents can lead ,to disasterous results.

!l ,, ~7~8!3 In United States Patent No. 4,317,645 dated March 2, 1982 in the name of a co-inventor herein, James Van Gompel, which patent is commonly assigned witll the present application, a device for restraining a cargo load has been described, which includes anelongated floor contacting member provided with an upwardly facing load bearing surface, and a generally upright member secured to the floor contacting member in spaced relation from the forward end of the floor contacting member, for engaging with the cargo load. A floor pierc:ing element is movably mounted on the floor contacting member adjacent to the rearward end thereo, and is normally dis-posed to pierce the floor when the floor contacting member is under load, to restrain movement of the load during transport, Patent No. 1,142,088 in the name of Greene, dated June 8, 1915, describes a load supporting xack specifically designe~
for use with hand trucks and having an open frame base and e.nd wall with diagonal braces joining the lower end of ~he e:nd wall to the base.
Patent ~o. 1,559,827 in the name of Wittman, dated November 3, 192S, descri~es a freight anti-creeping device including a metal plate for supporting cargo, cleats on the lower surface of the plate or yripping the floor, and a projection or lug on the other surface to which the cargo is secured.
Patent No~ 1,638,612 in ~e name of Baus, dated August 9, 1927, describes a cargo shipping device in which the car~o is braced on a pla~orm and rigidly held in position.

Patent No. 2,420,640 in the name of Acheson, dated May 20, 1947, describes a demountable pallet crib ~or storing and handling pallets. Essentially, the pallets are enclosed in a frame which is assembled about the pallets.
Between each end frame and an adjacent cheek frame inter locking means are provided so that the crib frame can neithex bulge at the corners, nor collapse when heavily loaded.
Patent No. 4,014,435, in the name of Rawley et al, dated March 29, 1977, describes a collapsible rack for glass sheets, which has a base dekachably secured to a pair o~ L-shaped supports, while a pair of struts is detachably secur~d to ~ertical portions of the L-shaped supports to support the articles in a vertical position. Banding is provided to unitize the glass sheets and the L-shaped supports to provide a stabilized rack.
None of the foregoing references provide a satisfactory solution to the problem of preventing damage during shipment to barrel-shaped containers or drums containin~ ha~ardous or explosive materials.
Sum_ary of the Invention In accordance with the present invention, a cargo restraining device suitable for restraining barrel-shaped containers or drums is provided, which includes a platform at least the load-bearing part of which is flat, and which is spaced from the underlying supporti~ surface or floor, by horizontal supporting members which extend the length of at least the flat portion of the platform, so as to provide a raised deck for the containers. At one end o the platorm, an upright or vertical frame is connec~ed - ~ ~27~8~ -. . . .. I
.', " ,, to the supporting member~, to resstrain the containers from fall- ¦
ing from the platform. The other end of the platform can be rounded over to define a snub-nose; or alternatively the other ends of the horizontal supporting members can project beyond the flat portion of the platform and be rounded into snub-nosed por-tions. In consequence, should the drums shift or move, wh~reby damage might ordinarily occur, the chimes or rims of the drums tend to flow around the snub-nose tor snub-noses if defined at the supporting members) without any significant damaye. Thus, I
the containers, instead of falling off when moved, gently slide about and of:E the snub-nosed portion or portions; and no abrupt discontinuous edges are encountered.
At both ends of at 1east the outermost of the horizontal support members, floor piercing member~ are provided, which are normally oriented to the floor piercing position, and ~irmly hold the platform in place. .
In a further a~pect of the inventionr a strap may ~e placQd around the.container~, and s~cured~a~ the~ends to the uprlgh~
frame, to further restrain movem~nt of the drums on the platform~
In the preferred mode o~ use of the present deYice, a plu~-ality o~ drums may be verticalIy loa~ed into a truck trail~, box . car, or the like, with the fir t loaded row being placed against the front wall of the trailer. Plywood partition~ or the like can be placed between ~ome or all o~ the successiYe roW~ to space the rows and limit row-to-xow dxum ~ontact~ At the b~k end o~

~ 2~0~39 the trailer, one ~r more of the present drum restraining device~
are loaded with drums, and the resultant assembly or assemblies positioned against the plywood sheet opposed to the last row of drums. The devices are held in place by the floor-piercing mem-bers gripping the floor. The containers are securely held, yet some movement is permitted; and in the unlikely event of pro-nounced movement, as when a strap breaXs, the containers can gently slide over or "flow" about the rounded snub-nosed end or ends of the restraining device without any serious damage to the said containers.
It is accordingly an object of the present invention to pro-vide a cargo restraining deYice for the transport of barrel~shaped containers, which requires no bracing, and which is otherwise highly effective in use and easily installed~
It is a further object of the invention, to provide a cargo estraining device for the transport of barrel-shaped containers, I
ich allows limited mov~ment of the contalners to occur without J
~onsequent damage to same.
A still fur-ther obejct of the invention is to provide a ~argo restraining device for the transport o~ drums containing ~azardous or explosive material3, which is easy to load and pre- 5 vents damage to the drum6 during transport.
_5_ ~ o~9 Another object of the invention is to provide a cargo re-straining device for the transport of drums containing hazardous or explosive materials, which requires no associated braces or enclosures.
A further object of the invention is to provide a cargo re-straininy device for the transport of drums containing hazardous or explosive materials, which is easily transported, and readily placed for further transport in a vehicle.
These and further objects and advantages of this invention will appear from the description of the preferred embodiments, which are exemplary only, the invention both in its parkiculars and overall concept being defined in the claims ~ollowing thi specification ~rief Description of the Drawin~ I

Detailed Descr~tion of the Preferred Embodiments Referring to the drawing~, the drum retaining devic~ 10 shown i~ Figures 2 and 3 has a deck or platform 12 on whi ch drums 14 are pla~ed (Figure 3~
An upright or vertical ~rama 16 is ~oined to the rear end of platform 12. This frame generally comprises a plorality o~
spaced posts 18 which extend upwardly frQm platform 1~ and are -7- supported b rosa-brace members 20 and 22.
~' ~ oa~
Platform 12 i5 supported and spaced from the floor by a plurality of horizontal stringer-like me~bers or legs 24 to which the platform is attached. The orward ends of the legs 24, which project slightly rom platform 12, are rounded into snub-nosed portions 26, as can be seen in Fi~ure-q 2, 3, and 4, so that the drums, if moved, as by jarring frorn their secured positions (packed against frame 16), can slide or "flow" about the rounded portions 26, rather than encounter a sharp edge at which damage could occur. The rounded portions 26 similarly ~end to protect drums not loaded on device 10 from being damaged.
The height of the legs 24, which determineæ the spacing of plat-form 12 from the floor, is somewhat critical in that it must be su~ficient to enable the drums to slide off the forward end of the platform, rather than fall; and yet, should not be so large that the drums would be damaged when they slide of. It has been found that a heig~t of about 4 inches is preferable, which enables the drums to slide off the rounded ends rather than Ealling o~f.
In Figure 2A, a further embodiment of the inven~ion appears.
The device lOa primarily differs from devica 10, in that instead of including rounded portions 26 (as in Figure 1), the me~bers 24a each terminate at forward ends 25/ and the platorm 12 is in this instance formed into a rounded front portion 27 along its entira fron~ edge. In this construction the rounded portion 27 is the~e-fore continuous, and thus al l the advantageæ of the separate rounded portions 26 are retained~ and indeed enhanced. The d~ice lOa al30 differ3 from dev~cQ 10 in that an enlarg&d cro~8-mem~er -8- C~
_9_ 29 replaces member 22 (Figure 1) to provide greater stability and strength. In other respects dc-vice lOa is substantially identical to device 10, and the ensuiny description may be regarded as applicable to either embodiment.
At least the outer pair of legs 24 (i.e. the leg 24 and 24a) have at each end a floor piercing element 28 similar to those described in aforementioned U. S. Patent No. 4,317,645.
In particular, each of the said outer supporting members are formed as channel section members which open inwardly in facing relation as shown in Figures 2, 3 and 4. At either end of the outer supporting members adjacent to the upright post 18, a filler plate 28 extends across the channel to form a box section portion 30, as best shown in Figure 6.
~ ach ~ox section portion 30 of the respective outer leg 24 supports a pair of spaced pivotal members 32 to thus pro-vide a total of eight (8) such members on the drum restrain-ing davice 10. The pivotal members 32 are each disposed on the legs 24 intermediate the leg and an outer support member 34 secured to the leg 24. The member 32 is pivotally dis-posed on a pin or bolt 36 which extends transversely throughaligned holes in the box section 30 and the outer support members 34. An inverted, generally J~shaped bolster plate 38 is secured on each side of leg 24 between the leg and corresponding outer support member 3~ in radial alignment with the corresponding pivotal member 32.
q '1 Z;~0~9 The pivotal member 32 includes an upper arcuate portion 40 which is at a given radial distance from the pivot axis and i5 rotatable relative to the bolster plate 38, and a diametrically opposed toothed portion 42 which is at a substant.ially greater radial distance from the pivot axis. Diametrically opposed, par-allel portions 44 and 46 extend between the arcuate portion 40 and the toothed portion 42. Due to the generally larger size and greater radial distance from the pivot axis, the toothed portion 42 will normally assume a downwardly disposed position as gener-ally shown in Figure 5.
The leg 47 of the bolster plate 38 generally precludes counter-clockwise movement of the pivotal member 32, as viewed in Figure 5. As generally shown by ph~ntom lines in Figure ~, pivotal member 32 is clockwise rotatable at least until the straight portion 34 makes contact w:Lth the corner projection 4~
of the bolster plate 38. It should be understood that the piY-otal mem~er 32 on the opposite side of the leg 24 is orientea a~
a mirror image on the pivot a~is and would ~e reversely m~vable for a similar result.
In the normally assumed position for the pivotal member 3~, the teeth 50 of portion 46 proj~ct downwardly ~Figure S). ~hen subjected to the weight of the load o the drums, the teeth 50 are driven to penetrate or pierce a wood floor 52. When the drum retainer dev~ce is seated on the floor and out of ~ervica, th~
pivotal members 32 may be caused to as~ume t~e phantom line posi-tion of Figure S~
-10- ba .
3L;;:2~ 39 . '' ., -.
With further reference to Figure 5, it wi].l be observed that in the normally as~umed position of the pivotal members 32, the rearwardly facing edge of the te~th 50 extends vertically or nearly so. Under the severe demands imposed upon a loaded truck trailer 52 mounted for piggy-back service on a railroad car as shown in Figure 1, the trailer and its cargo of drums may be sub-jected to impacts from the front and baek, part.icularly durin~
bumping or freight car sorting operations. Accordingly, a strap 54 is wrapped ~round the drums, the ends 56 of which are secured to posts 18 (Figure 4) which restrain the drums from movement.
(For simplicity strap 54 is not shown in Figure 3~.
Moreover, in the case of frontal impact, the teeth 50 with vertical or near ver~ical rearwardLy facing edges, will substan-tially maintain position to Xeep the drums from mQVing toward the rear -- the tee~h 5Q will thus kaep the device 10 from movin~
toward the right in Fi~ure 4. In the event of a rear impact on the trailer/ howaver, the ~eeth 50 can more readily be diRlodged forw~rdly to assume a new position, ~hu~, whlle some movement of the drums on the platform is permitted, the d~ck i~ firmly held. Should the strap breaX or not be fastened, shi~ting of the drums rssults in their sliding over the round fvrward ends of the leg~ 26 (or over the round~d ed~e 27 of tha platform in Figure 2A~ without engaginy any sharp edge which could damage the drum~.
~/ I
~,~2~0~q- ~
In the use of the drum retaining device 10, a fork lift unit is generally used and initially seats -t~ae drums on the retaining device Erom the front. After the drums are properly seated on the drum retaining device 10, the device with the drums thereon is pick~d up from the rear and moved into location. For the load-ing illu~trated in Figures 1 and lA, a pair of retaining devices 58 and 59 loaded with drums are seated in the trailer to secure the integrity of all drums in the orward direction between the retaining devices and the front end 51 of the trailer 52. A~
previously mentioned, one or more plywood or other temporary separating wall~ 53 are mounted between rows of dr~s to assure proper spacing and minimize the possibility of damage in the : tightly packed drums. When necessary and/or desired, r~tainers 10 may also be usQd to generally preclude lateral movement as well.
While th~ present invention has been especially de~cribed in terms of specific embodiment~ thereof, it will be understood that numerous modifications will be apparent to those skilled in the art without departing significantly from the invention~ Ac-cordingly, the invention i8 to be broadly construed and limited only by the following claims.

At least the outer pair of legs 24 (i.e. the leg 24 and 24a) have at each end a floor piercing element 28 similar to those described in aforementioned U. S. Patent No. 4,317,645.
In particular, each of the said outer supporting members are formed as channel section members which open inwardly in facing relation as shown in Figures 2, 3 and 4. At either end of the outer supporting members adjacent to the upright post 18, a filler plate 28 extends across the channel to form a box section portion 30, as best shown in Figure 6.
~ ach ~ox section portion 30 of the respective outer leg 24 supports a pair of spaced pivotal members 32 to thus pro-vide a total of eight (8) such members on the drum restrain-ing davice 10. The pivotal members 32 are each disposed on the legs 24 intermediate the leg and an outer support member 34 secured to the leg 24. The member 32 is pivotally dis-posed on a pin or bolt 36 which extends transversely throughaligned holes in the box section 30 and the outer support members 34. An inverted, generally J~shaped bolster plate 38 is secured on each side of leg 24 between the leg and corresponding outer support member 3~ in radial alignment with the corresponding pivotal member 32.
q '1 Z;~0~9 The pivotal member 32 includes an upper arcuate portion 40 which is at a given radial distance from the pivot axis and i5 rotatable relative to the bolster plate 38, and a diametrically opposed toothed portion 42 which is at a substant.ially greater radial distance from the pivot axis. Diametrically opposed, par-allel portions 44 and 46 extend between the arcuate portion 40 and the toothed portion 42. Due to the generally larger size and greater radial distance from the pivot axis, the toothed portion 42 will normally assume a downwardly disposed position as gener-ally shown in Figure 5.
The leg 47 of the bolster plate 38 generally precludes counter-clockwise movement of the pivotal member 32, as viewed in Figure 5. As generally shown by ph~ntom lines in Figure ~, pivotal member 32 is clockwise rotatable at least until the straight portion 34 makes contact w:Lth the corner projection 4~
of the bolster plate 38. It should be understood that the piY-otal mem~er 32 on the opposite side of the leg 24 is orientea a~
a mirror image on the pivot a~is and would ~e reversely m~vable for a similar result.
In the normally assumed position for the pivotal member 3~, the teeth 50 of portion 46 proj~ct downwardly ~Figure S). ~hen subjected to the weight of the load o the drums, the teeth 50 are driven to penetrate or pierce a wood floor 52. When the drum retainer dev~ce is seated on the floor and out of ~ervica, th~
pivotal members 32 may be caused to as~ume t~e phantom line posi-tion of Figure S~
-10- ba .
3L;;:2~ 39 . '' ., -.
With further reference to Figure 5, it wi].l be observed that in the normally as~umed position of the pivotal members 32, the rearwardly facing edge of the te~th 50 extends vertically or nearly so. Under the severe demands imposed upon a loaded truck trailer 52 mounted for piggy-back service on a railroad car as shown in Figure 1, the trailer and its cargo of drums may be sub-jected to impacts from the front and baek, part.icularly durin~
bumping or freight car sorting operations. Accordingly, a strap 54 is wrapped ~round the drums, the ends 56 of which are secured to posts 18 (Figure 4) which restrain the drums from movement.
(For simplicity strap 54 is not shown in Figure 3~.
Moreover, in the case of frontal impact, the teeth 50 with vertical or near ver~ical rearwardLy facing edges, will substan-tially maintain position to Xeep the drums from mQVing toward the rear -- the tee~h 5Q will thus kaep the device 10 from movin~
toward the right in Fi~ure 4. In the event of a rear impact on the trailer/ howaver, the ~eeth 50 can more readily be diRlodged forw~rdly to assume a new position, ~hu~, whlle some movement of the drums on the platform is permitted, the d~ck i~ firmly held. Should the strap breaX or not be fastened, shi~ting of the drums rssults in their sliding over the round fvrward ends of the leg~ 26 (or over the round~d ed~e 27 of tha platform in Figure 2A~ without engaginy any sharp edge which could damage the drum~.

~,~2~0~q- ~
In the use of the drum retaining device 10, a fork lift unit is generally used and initially seats -t~ae drums on the retaining device Erom the front. After the drums are properly seated on the drum retaining device 10, the device with the drums thereon is pick~d up from the rear and moved into location. For the load-ing illu~trated in Figures 1 and lA, a pair of retaining devices 58 and 59 loaded with drums are seated in the trailer to secure the integrity of all drums in the orward direction between the retaining devices and the front end 51 of the trailer 52. A~
previously mentioned, one or more plywood or other temporary separating wall~ 53 are mounted between rows of dr~s to assure proper spacing and minimize the possibility of damage in the : tightly packed drums. When necessary and/or desired, r~tainers 10 may also be usQd to generally preclude lateral movement as well.
While th~ present invention has been especially de~cribed in terms of specific embodiment~ thereof, it will be understood that numerous modifications will be apparent to those skilled in the art without departing significantly from the invention~ Ac-cordingly, the invention i8 to be broadly construed and limited only by the following claims.
