BASKET.

Application iled December 12, A1919, Serial No. l$114,333. Renewed December 14, 19,23. 'f

To all whom "it may concern: j

Be it known that I, FREDRIGK KRETzsoH- MAR, a citizen of the `United States, and a resident of Chicago, in the county ofCOok and State of Illinoishave` invented certain new and useful Improvements in Baskets, ofwhich the following is a full,4clear, and

l ,exactV specification.

This invention relates to improvements in baskets provided with wood runners for reducing friction when-pushing them, and particularly when large 'and heavyy over floors from one point to another andtherebyavoiding the greater force otherwise required for liftingand carrying them.

For the purpose of securingthesewood runners tothe bottom ofv thebasket, it has.`

heretofore been thecommongpractice `to conc "struct therunners of twovpiecesfor the passage of the bottom wires between them and to clamp the .bottom wires Vbetween these two pieces, at intervals of the runners, with boltstightened by means `of nuts `on their inner ends and having heads countersunk at their outer ends in the runners, which in practice, however, is objectionable` for the reason that the bolt heads soon become exposed from the frictional wearing down of the runners and as a result of which the bolt'heads coming incontact` with the ioor not only increase its resistancey to the runners, but that in a little while the floor is scratched, grooved` and otherwise injured and defaced by the bolt heads.

In the construction of the baskets above referred to, it has also heretofore beenthe common practice to construct. the foundation of the bottom of the basketv of wires, separate andA distinct from other wires, forming the foundation for the sides of the basket, and to secure the adjacent ends of `the wires for the bottom and sides of the basket to longitudinal bars or sticks extending along the side edges of the basket.

The prime obj ectof my invention broadly stated, is a basket the bottom` foundation of which is formed of wires between which strips of willow, rattan, or other.V suitable material may be woven, provided with one or more runners, each of which is constructed in its-entirety from a single piece `wires may bethreaded and preferablyat a point substantially removedfrom thebottom and wearing `surfaces of the runners. i `A further object of `this'invention is; a

basket having runners, .each of which is l formed of a single piece` of material perforated at intervals for the passageofthe bottom wires for the basket, whichy perfora- `durability of the bottom of and also the basket as a"V whole, which perforations further provide a means by which itis both possible and practicable to have the bottom and sidewires of a basket integrally connected. i

i With these ends in view, my invention finds yembodiment i`n certainfeatures of novelty in the construction', combinationand arrangement of `parts by which the said ob-` jects are attained, all las hereinafter fully described with referenceto the' accompanying drawings, and moreparticularly pointed out in the claims. j,

In said drawings,-` Fig. l is aplan view of a portion ofthe frameworkffor a basket in which lmy invention iinds its embodiment;

Fig. 2 is a transverse section taken on the line `Q--Qof Fig. l, andl f j Fig. 3 is a detail, partly in section, showing the meansby which the bottom end bar of the basket is secured to and adjacent the ends of the runners, and the means by which the wires for'the ends ofthe basket are separated and secured in theirfoperative position.` l

In constructing the bottom and sides of the basket indicated in the;drawings, 4runners 4, of which there may beany desired number, of a length `corresponding with `the size of the basket to be made, and rectangular in cross-section, are provided atintervals of the length with perforations 5, preferably located in a plane substantially above their wearing" surfaces and are connected at their ends by an .end bar 6, by means of screws and preferably vby a wire nail 7 driven through the "end bar 6 into the ends of the runners 4;.

To the corners of the frame so formed are secured one or more posts 7', usually of rattan or willow,` by means of vWire* nails or binding wires connecting them with the' end bar 6 or the runners, as may be, and at least withfsnicient rigidity to.' enable the subsequentlyA woven willow" or rattan or other suitable strips to permanently lock them in their operativev position tothe runners, forming the bottom and side edges of the basket, as is commonly followed in the construction of baskets having a fiat bottom.

Havingthus constructedl theV y'bottom frame and the corner posts for the basket of my invention, wires Sand 8a, of sufficient length for the foundation ofthe bottom and sides yof the basket, are threaded yin pairs through the perforations `in the runners 4 to forin'the bottom wires which are bent upwardly to form'the foundationwfor the bottom `9 and ,longitudinald` sides ofV the basket, the free endsv ofthe upwardly eX- tending wires bein'gbent outwardly at l0, thence downwardlyas at 11, inwardly as at 12', and upwardly asiat,- 13, to provide van anchorage'for strips of rattan or willow 14, interwoven for the construction of a substantially thick and strong rirn l5 `for the upper ysideedges of the basket, and also continuously therewith for both ends' basket, as will be presently described.

Any' number of'ru'n'ners 4 may beV used. but, as shown in the drawings, there are three, two fof which extend along the longitudinal side edges ofthe basket bottom.

Of these runners it is now to loe observed that their opposing perforations 5 register transverselyl of theibasket; that the wires and 8a in pairs are passed' througha single perforation in the central/runner and thence diverge in opposite directions to the side runners, whence theyv again diverge upwardly in the opposite direction to the rim of the basket; and that as a result of ,their divergence the wires 8 and 8a respectively, pass through alternate perforations in the side runners and form a network of closely fitting diamondlike spaces whichin the bot tom of the basket adjacent the side runners are ktruncated and likewise in the rim, tlze diamond-shaped spaces of which, however. extend lengthwise at a right angle to'those in the bottom. f y

With each pair of wires passing through the side and central runners and diverging from the former, as above described/ther operate not only to support the runners, but as stay and tension chords, sustaining the runners against longitudinal movement in eitherdirection from the force of blows dil rected against the ends of the basket and the force of the frictional resistance when `shoving the basket over a ioor and wherebythe distortions ofthe bottom frame are prevented and its rigidity and durability as a whole correspondingly increased.

Inthis connection it is to be noted that thebendlla (see'Fig. 2) between. and,con-

of the the bottom wires and transversely of their frame the lateral compression of the frame due to force directed laterally. therethrough.

Concerning this distribution of forces from impact against the bottom rim of-lthe basket, it'may be further observedI that, filled as are the spaces-between and surrounding .the wiresl of both the bottom4 and rim L with closely interwoven stripsof willow or rattan, the centering-of:forcestend ing to and frequently fracturing. or., breaking the woven fabric, is substantially yand materially reduced.and this. in a basket that, to all intcntsand purposes, is. as :i whole a substantially rigidhstructure, the flexibility of which .isconfined almost in its entirety to the rim.

Having described my invention, whatnl claim as new anddesire-to secure by Letters Patent is x l.

A basket provided with runners-each consisting of a singlepiecehaving perforations transversely therethrough for the pas-- sage of wires, a pair of wires passing Ithrougheach of saidvv perforationsvdiverging therefrom each of which pairs of wires eX- tend upwardly into the rim of said basket and adapted for the weaving of strips of rattan and other suitable material between the wires of the several pairs.

6. A basket havinfb single piece runners transversely perforated, provided with wires passing in pairs therethrough, which wires are bent upwardly at a point distant 10 from the outer runnersand provide a spate between their upright portion and the sides 4of the outer runners substantially as and 'for my hand and aiixed my seal this 29th day 15 of November, A.
