(c1. desfase-i This :invention relates :to .means for securing ireight .against shifting or :for separating ship- .ments of .less .than .fcarload lots .of packaged or bulk merchandise .in .freight compartments such .as railway 'box cars, imotor ltruck vans, strong V,rooms of yessels, :special cargo lockers, store looms, .or .in any yother .application where it .is .necessary .tosecure-stacked cargo or merchandise against shifting within a confined space pr to separate various-lots of shipments.

In carrying outtheinvention lengthwise track- -waysare installed fthe sidesor wallsof the ve- 'fhicle or cargo space, ya plurality :of trackways sbeing usually provided at leacn -fsde of the ferrea, 1spaced vat .desirable ,distances apart and running .parallel sto :the-floor andeeiling. Cross stretchers -or braces vare provided which .may be moved1=t0 :any desired position .on the trackways, vto suit the cargo vor merchandise to .be secured, and lockedin such position. rIhe construction issuch that the cross stretchers may be pressed against the :merchandise .so .as vto hold the samenrmly in vplace with thedesired degree of .compressive force.

yone the crcsssstretcnces isslicwn atwl and flange 26 on the face plate. The ends of the hook plates are received ireely in the recesses 28 and support the stretchers upon the face plates, while they are being slid to desired position for use. One, or both, of the hook plates 34 is preferably mounted for limited free longitudinal movement on the stretcher so that the stretcher may be slid freelyalonglthe'trackwayirrespe'ctive of the oidinaryvariations"in-gauge"due to bulging of the compartment walls or similar causes. In the construction shown the hook plates are provided with elongated slots 38 through .which pass large headed studs 4B riveted in the top wall of the stretcher. As the anges 36- of thehook plates lie behind the Ilanges A26 ofithe face'platesythere is no danger of the stretcher becoming displaced from the trackways. A

For locking the stretchersA-in desired position longitudinally of the trackways, locking 'lugs l2 are provided which have T-shaped heads 44 which may be' insertedfin any.k desired v,corresponding -pair of Yslots inthe race; plates of 'the trackway.

The heads dil are of such size that their 4ends L'mayxpass through 'thefvertical armszfof the Vslots'Zi), whereupon the lugs are slid longitudinalyly until the headsfll `lock behind the plate above 1 and below the4 horizontal arm portion 24 of the slot furthest from thestretcher.'` The lugs are -provided with internally .threaded holes 6 .through which pass .jackscrews 48 which have .stems 50 passing through slots in the wall of the stretcher and through corresponding. slots -52 in reinforcingplates Ell.. The! screws are retained in the slots by suitable means such as -collars 56 'shown in -dottedflines in Fig. 2. Means are provided for rotating the jackscrews, such as 'bars58,=slidably mountedl in iholes in the ends of the jackscrew'sfan'd prevented from dropping out 4by pins E0. @The-,lugs 42 are preferably pro- `videdwithfbroad-iaceslZ and overhanging portionsd 'on their sides-furthest from the stretchers sofas to providellav i'irmY-bearingfor. the lugs against thelface plates-When lpressure is applied thereto by thetighteningrofthefjackscrews; The v adjustable-Screw 'connection' between the lugs and -the stretchers-perniitsfthe-stretchers -to be located `at .any point valong A'the trackways by selecting proper lslots'forl application of-.the lugs and then adjusting theja'cksc'rews.- The jack- `screwsare slightly-longer than the distance' be- Avtween '-adjacentllslotsfso that universalr adjustability lis provided. Therjackscrews may also be used to force" the stretcher againstlthe'cargo when necessary so as to hold-thesame"-iir-mlyr in position. The slidable bars 58 permit the screws Ytobe rotated a one-half turn/ati a time to any extent necessaryA It will `be seen that the lugs r42 interlock with the'face plates-'so that they are always properly engaged therewith irrespective of variations ofthe gauge of the trackways.

The ends 'of the'jackscrewsbeing looselyfmounted in -the slots 52 in the stretcherfmay move longitudinally thereof -suihciently to take care of such 'The face DlatesHlA have-a" plurality of `closely 'spaced slots A'l2 therein'ij which maybe of any "desired shape such 'v asf',round orY rectangular. ,'Th'es'e slots are preferably spaced vcloser together than the slots *20,the construction'previl* y losly described;n The "stretchers 14`comprise` 4 metal members 'i6 o box like form which are sheathed if necessary by a sheathing 32 of plywood or the like. Supporting hook plates 18 are provided at the ends of the stretcher, these hook plates being preferably mounted, in the construction shown, on the inside of the top wall of the stretcher. These plates are provided with lelongated slots "52, as in the previous construction, the Yplates being adjustably retained at their inner ends by studs im. Passing through the slots at the outer ends o1" the bracket plates 152 carry projecting lugs or locking arms 86,

which are adapted to project into corresponding slots 'i2 in the face plates. Secured to the upper ends of the bearing pins Si! are heads 88, such upper ends being preferably Ysquared as indicated at 9B `so that the heads 8S are held against turning with respect to thelatch members. .Lever arms- 92.4are pivoted tothe heads 8S; the lever arms having means for locking them in .adjusted position which are shown as comprising a pin on the lever arm which is adapted to engage .in one or the other of the holes 96., in'a raised iiange-QB of ac locking plate lil secured to the top of the cross stretcher. Withthis construction the levers 92 maybeswung upwardly, as shown indotted lines in Fig. `6,.,fso Vas toldisen'- -gage the pins from: the -lockingvplates *,The levers are then rotated far enough to permit .the

lugs to disengagev thezslotsgin' therme-plates, whereupon the stretchers may beslidalong'the `trackway to the desired position. The levers are nowswung. sov as to engage thelugs'f inthe corresponding slots and are` lockedcin such position by engaging the pins '.1912 `on the endsof the levers with appropriate holes By choosing 'a .proper pair of slots'v and adjusting the angulari- :ty of the lugs any adjustment .is possible;The

lugs are of such length with respect to the distance `between adjacent slots as :tolprovide whatever range of'y movement is necessary, land *they are also of vsuch length yas yto *project well into or throughY the slots so that .a considerable variation vin the gauge of the trackways is permitted without danger of Ithe lugs, not properly engaging in the slots.l f' By rotating Athe .latch struction to the cargo:i Y' f Where the trackwaysf'are `vmounted in the side walls''of abox carA orother compartmenthaving side doors, portable sections of the'trackwaycan berprovided to'tspanfthe door area-so as to Ypermit "the stretchers being-used tov secure cargo loaded oppositetoadoorope'ning;m
