Oui` invention relates to improvements in laundry devices, and more particularly to those laundry devicesemployed in connection with the washing, rins" bluing bleaching, and other processes inci ent to the preparation of laund The general object of our invention is to provide means adapted to ellect a substantial saving of' equipment, time and labor in lo laundries, thereby greatly increasing the eiliciency of establishments engaged in this line of work.' i

'A more articular object of our invention isI to provi e a novel, laundry net of flexible,

u durable metallic construction, incorrodible to the acids and alkalies used and non-absorbent to other chemicalsemployed in laundry work,

while adapted to give service over an indefimte n In modern laundry practice, it is customary known, a considerable percentage of he soap, y in t e above alkali, and other solutions use mentioned processes are absorbed directly into the fabric net containers. By repeated tests, it is found the average cotton fabric laundry net now in use and weighing approximately fourteen ounces, absorbs two and onehalf times its own weight of the solutions emloyed.` In other words, a fourteenounce aundry net absorbs approximately 35 ounces of solution. The immediate result of this great absorption of solution is a quick llution of the rinsing water into whic the washed articles are immediately immersed after washing. Seven rinsings are generally employed to :Eme the washed articles from the i washing solutions. y I t is, of course, understood that during .the washmg process the nets with the articles therein are placed in a large drum or vat f a partially illedwith asoap solution andlthe drum rotated, by the suitable application of power, two or three times in one direction, then immediately followed by an equal number of revolutions in the o posite direction,- this cycle being repeats until the desired cleansing is obtained. The nets during the rotation of thedrum are tumbling about therein in the solution, it being observed that a mechanical squeezing and kneading of the rment is effected by the falls and rebounds t ereof, which assists in drawing in, expelling and communicatin movement to the solution into, around and t rough the net and its contents. '.lhhis same rocedure isused in cong5 nection with the ot er processes preparatoryv to. drying of the artic es in the centrifugal machine.- i

The method above indicated is that now employed in moderncommercial laundries,"10'i v vbeinlg eicient.vl However, in actual practice, 1t 1s esesntialy mechanical and thorou bly found they fabric nets by constant immersion in the various solutions used are subject to r rapid deterioration', thus: soon 4resulting in 75 rupture and disintegration of the net. As this comparatively early breakdown orbrsting of the net is likely to occur to other' nets of the sameage and usage atabout the same time, considerable vinconvenience isl gq caused by the intermingling of diverse articles 4belonging to different. individuals, thereby occasioning greatconfusion and quite often loss of some oftheY articles through inability to identifythe owner. sa other respects, the textile net heretofore 1n" use did not permit a's free a flow of the solution therethrough as would be-de'sired, necessitating a longer' period of immersion 1n the drum.' Enumerating, therefore, briey the 1 disadvantages of the present textile net in use for the purpose of setting .forth the superior method. and construction now to be defined in detail, it may be said the defects of the textile net are (1) the absorption of solutions, (2) the im edance of flow of the solutions within the Ibags, (3) early disintegration of the bags, (V4) time required to' complete the several processes.

By means of our invention now to be described, we have succeeded in overcoming the above disadvantages in addition to which we secure important mechanical advantages in that a freer flow 'of solution is achieved through the more open interstices of our metallic mesh; amore thorough kneading,

effect of the garments within our net is obtained by reason of its compactness and freer transmission of the movements arising during its tumblings in. the drum, lwhile being incorrodible and non-absorbent to the Solu" metal rings 11, which, shownfin Figure 2 vthe-utmost lexibilit with a comparatively are interlaced in a manner whereby each ofY the, rings are passed'threugh three other sim-,I ilar rings, this method providing a mesh of 'large orice, for the'ingress and egressl of the solutions'in whichthe bag with its contents is immersed. The ends of each of the rings or links 11 are smoothly soldered or brazed togetherfwhereby an endlessV non-abrasive 4metallic fabrication is obtained. As a' clo- .sure for the net, we provide what iscom monlytermed ablanket safety pin 12 which serves tohold the` mouth of the net closed during manipulation thereof while the clasp "13 permits the detachment of the safety Vpin when the net is to be emptied. `As ameans be `placed on the joint 14 of the pin.

-have found by experience nearly all of the so-called familiar metals to be unsuitedA l for the purpose of a Vnet to .be employed as a container for articles during the laundry process above indicated, but as an yimportant feature of our invention, wehave ascertained by experiment an alloy termed Monel metal to admirably adapt itself to the functions required for use in laundry work. This metal is practically incorrodible to the normalsol'uthen, our invention in connecl `as hampers and carriers Aof heterogeneousbe made oval or ot ofidentifi'cation, a reference charactervmay v neueste` tions employed in laundryiwork, which for s the'most part are alkaline and in some cases acidulous, the latter being employed to counteract and neutralize the presence of alkali remaining in the washed garments. The soap and bluing solutions, of course, are not as inj urious in their effects as the alkali and acids indicated, nevertheless the bleaching process again is a powerful caustic and destructive agency to the textile nets heretofore employed, which, unlike the garments washed, were almost continuously subjected to the action ofthe solutions. Particularattention is called to the comparativel large interstices of our metallic net mesh w lch provide for a much freer liow of solution than was possible to the textilenets used.

We have found in actual practice that the i f washing process may be more quickly accomplished by the use of these nets by reason of the more free flow-of solution into and out of the bags thanV was possible tothe textile nets heretofore employed; in addition to which it is found that at least one or two of the rinsings required can be dispensed with g other processes to Vwhich the washed` and rlnsed articles are now subjected, and since j the articles are laundered with more mechanical and less chemical treatment, a longer life to the articles so treated is secured. As a coni sequence of our method and themeans employed, a substantial saving of time, labor,

consumption of power and materialis clearly',

' demonstrable.

We are aware of the use of metallic meshes s ies of merchandise b ut the use of amet-al'- 11o' mesh of the herein detaileddescription we believe to be new in the laundry art.

While we have described the nature of our y invention and the structuralfdetails' thereof with particularity, it will be understood that Aminor variationsl and chan es may bemade .therein without departing rom the spirit of our invention. It will be obvious for instance that a larger or smaller metallic mesh may be substituted for that indicated, or that for example the configuration of the rings could er kdesired sha e.

What we claim as new and desire -to secure, by Letters -Patent is: ,Y

1. Al laundry net fholding fabric articles immersed within a liquid to be mechanically agitated for 'the purpose of treating the f .articles contained therein, comprising ametallic meshingl constructed of inter-laced rmgs, said rings having complete continuity and smoothness throughout, and composed of metal havin non-corrosive properties. 2. A laun Y net for holding fabric articles immersed wit in a liquid to be mechanically agitated for the urpose of treating the articles contained t erein, comprising a metallic meshing constructed of inter-laced rin said rings having complete continuity an smoothness throughout, each of said rings arranged to engage three ad'acent rings in the body of the meshing, an said rings composed of metal having non-corrosive properties. y

In testimony whereof we have signed bur names to this specification.
