(Cl. 206-435) 1 My invention relates to improvements in bun dles and the preferred method of producing them, with particular reference to use in connection with the preparation of ingots for handling ‘and shipment. ' ‘ It has been the practice, for example, to “run” or cast magnesium into pigs or ingots weighing about ?ve pounds each, such ingots being in the form of elongated bars substantially trapezoidal in cross section, with the taper ‘toward What is herein referred to as the top faces of the bars. and without any substantial danger that an in got will slip out longitudinally even if looseness should develop in a bundle when handled or dur ing transportation. For accomplishing this ob ject, a plurality of ingots are arranged in partial bundles or‘sub-units, held together by a ?exible metal binder formed into a loop about some of the ingots of the sub-unit and engaging the notches of the ingots and tightened in a novel vmanner for holding the ingots of the sub-unit ?rmly in position, two or more of such sub-units being bound together to make up the complete As cast, each full ingot has a transversely posi bundle or whole unit. tioned notch or groove across its top face at about In the preferred arrangement a partial bundle the middle point therealong to facilitate the sep aration of the whole into two approximately equal 15 or sub-unit constitutes six ingots-two pairs with their broader bases abutting and spased apart halves. to form, in effect, two inwardly converging chan Frequently it is desirable to be able to handle, nels-into which the two other ingots of the sub store and transport the ingots in groups or bun group may be wedged—-and a binder looped about dles rather than individually. In this condition '1 the‘ ingot pairs and tightened by the action of they are more adaptable to lifting and carrying the other two ingots of the sub-unit wedged into by cranes and trucks with consequent reduction‘ the converging channels. In other Words, the of manual effort and time consumed. And they loop of binder extends about the two ingot pairs are more adapted to bulk transportation. How of the sub-group while the other two or interme ever, the satisfactory bundling of ingots has been _ difficult because of the tendency to become ‘loose 25 diate'ingots of a sub-group are positioned out side of the loop but in wedging relationship be with handling or during shipment. Metal ingots are usually very difficult to hold in groups or bundles. In the ?rst place, the in gots, because of their rigidity and non-compres sibility, cannot well be sprung or compressed as 30 an aid to effecting and maintaining tightness of a bundle. In the second place, ingots are not uniform in size and shape and their surfaces are tween the ingot pairs positioned within the loop, such intermediate ingots beingpressed inwardly, by severe pounding or otherwise, for tightening the loop with‘re‘spect to the ingots. Pressure means-is‘ then applied to the whole unit for hold ing the intermediate ingots from movement out of wedging relationship with‘the sub-unit, such pressure means beingpreferably in the form of normally rough. This roughness is such that when the bars are placed in position for bundling 35 a flexible metal binder secured about one or two of the subeunitarrangements. all the high points on one bar do not ?tl into de In the application of the ?exible binders into ‘ pressions on adjacent bars and during subsequent position,‘ they are preferably arranged in engage handling of bundles slight rearrangement of bars ment with the transverse notches or grooves in occurs which usually permits closer nesting ‘of bars with the high points of one ?tting more de? 40 the exposed top faces of'the ingots, serving thus substantially‘ to bind the bundle structure‘ as a ‘ nitely in depressions in the other, with resulting whole so ‘as to prevent separation‘ ‘of, theingots looseness in the steel strap or other securing me and the sub-units and undue relative movement dium of the bundle. With inadequate tightening longitudinally of the sub-units with respect to, of the bundle, one or more of the ingots is likely ‘ ‘ , to slip out of a bundle when it is tossed or thrown 45 each other. It is a further object of the invention to im or lifted with the ingots vertical or when sub prove bundles and methods of producing the same jected to the jars, jolts and shifts of transporta- ‘ tion. It is the principal object of this invention to provide an improved method of assembling and bundling ingots or like articles, whereby improved bundles may be ‘produced capable of being han dled and moved to advantage without any‘ sub in sundry details‘ hereinafter pointed out. The preferred‘ arrangement of the parts and the means by the use of which the method‘ is preferably carried out are illustrated‘ in‘the accompanying drawing,‘ in which:_ ‘ ‘ I ‘ Fig. 1 isa side face view of an ingot of a type stantial danger that the bundle will become loos adapted to be bundled advantageously by my ened under any ordinary conditions of handling, improved method; 3 £409,750 Fig. 2 is a vertical cross sectional view taken substantially at the line 2-2 of Fig. 1; Fig. 3 is a side view of a jig of a preferred form, partly broken away, having a plurality of ingots in position thereon for starting the forma tion of the improved bundle; Fig. 4 is an end view of the ingots of Fig. 3 4 with respect to each other so as to increase slightly the distance between such outer bars. The arrangement with respect to the initial size of the loop I8 and with respect to the initial position of the several bars is such that by the time the intermediate bar 24 reaches the position as shown in Fig. 5 by virtue of heavy pressure but with two additional ingots in position and thereon, the loop I8 has been tightened and per with the end portions of the ?exible binder con haps stretched slightly so as to cause the six bars nected together to form a loop; '10 as shown in said Fig. 5 to form a very compact and Fig. 5 is an end view of the arrangement of strong unit portion of a bundle.

The arrangement of the suppOrting faces of the standards I4 and table I5 at an angle from the horizontal is'such that the bars I‘I, I9 and 28 normally settle into the desired fairly snug engagement with each other. As the next step of the process, (see Fig. 4) two additional bars 2| and 22 are placed in position in base to base relationship with the bars I9 and 28 respectively, stood that the invention is not to be limited to such arrangement and method except so far as the claims ‘may be so limited, since it is possible that changes might be made in the arrangement or the ‘method without departing from the spirit of the claims. I claim: 1. In a bundle, the combination of two up wardly tapered ingots arranged in base to base relationship to each other, two other upwardly connected together to'form a fairly loose loop 6.0 tapered ingots elsoarranged in base to base rela tionship to each other and positioned in spaced about the bars I 9, 28, 2I and 22. In the arrange after which the end portions of the binder I8 are ment shown, a ‘connector 23 of any approved form is shown for effecting the connection of the end portions of the band or binder, which connector is adapted preferably to allow an in crease in the loop length under suitable strain. A sixth bar 24 is‘ then placed in position on the outer face of the binder I8 and is driven or otherwise forced downwardly toward the oppo sitely positioned intermediate bar I‘! so as to take up any slack in the loop binder I8. The bar 24, as it moves inwardly into position between the outer bars 2| and 22, has a wedging relationship with such outer bars so as to force them outwardly relation to said ?rst named ingots at one side thereof, said ingots being provided with aligned transverse notches thereacross at intermediate 65 points thereon, a ?exible binder in the form of a loop extending about said ingots and engaging said notches, two other upwardly tapered ingots interposed between said ?rst named ingots and said second named ingots outside of said binder and having transverse notches in their top faces engaging said binder, said third mentioned ingots serving when pressed forcibly toward each other to tighten the binder strongly in interlaced posi tion with respect to the several ingots, and means 7.5.
