UNITED STATES PATENT OFFICE RALPH B. BAKER, OF CHICAGO, ILLINOIS LAUNDRY BAG" Application filed Kay 18, 1932. Serial No. 611,989. i

This invention relates to laundry bags and improved laundry bag which is elastic and will be described as incorporated in a connon-absorbent and will more effectively retainer for confining the articles of laundry sist wear and deterioration. to prevent dispersement thereof during the Other objects and advantages of this inhi d d i ro s, vention will become apparent from the fol- 55 Heretofore, it has been the practice to use lowing detailed description, together wlth net bags made of cotton or like material, in the accompanying drawing. which the laundry was placed for washing.- On the drawing: Many objections to the use of such a bag Figure 1 is a plan view of a laundry bag mi htbe set forth at length, however, it will incorporating my invention, and shown as 60 su cc to mention the more important ones lying flat on a table. h o, 0 Figure 2 is an elevational view of the bag It has been found that the net bags formed shown in Figure 1, illustrating the same as of "cotton and the like rapidly deteriorate when filled with clothing or other laundry when constantly exposed to moisture and to ready to be washed. 65 the relatively caustic washing fluids which F igure 3 is a sectional view taken through are being used.

Adjacent An object of this invention is the provision the top of the bag as indicated at 14 and 15, of an improved device of the class identified the bag is'free from perforation forthe purwhich overcomes the objections above set pose of reinforcing the bag adjacent the top forth. Another object is the provision of an [where it may normally receive a great amount of strain as a result of handling the bag when filled with laundry. Between the portions 14 and 15, are disposed a plurality of parallel slots 16 through which a large safety pin or the like 17 may be threaded when the top of the bag is gathered together in the manner shown in Figure 2. A suitable tag 18 is preferably fixed on the pin 17 for identifying the laundry.

In Figure 4 is illustrated a modification of my invention comprising a sheet of material folded and secured in the same manner as described with reference to Figure 1, but other means is disclosed for releasably looking the open end of the bag in closed position. Such means consists of a reinforcing binder 21 of suitable material such as nonelastic reinforced rubber or fabric preferably vulcanized within the material of the laundry bag and extending thereabove as illustrated, providing a suitable support for a hookless fastener of any well known construction comprising a relatively stationary elements 22, and a movable member 23, for locking the elements 22 on opposite sides of the open top, in in'terengaging position.

Figure 3 illustrates the manner in which an elastic sack of the type' herein described is capable of yielding and stretching, when'a number of bags may be crowded together in such a condition that both ends of a bag may be held sufficiently tight to make them relatively stationary, and at the same time pressure may be applied to an intermediate portion which would cause excessive strain were it not for the fact that the material is elastic. In devices of the prior art, 'such strain caused particularly when the laundry bags are in the centrifugal drier, result in a tearing of the bags which makes the same useless because of the fact that cotton bags cannot be successfully repaired. A bag of the type herein described if torn, may be readily repaired by any well known vulcanizing process.

It will be appreciated from the foregoing description that I have provided an improved laundry bag which exerts little or no wearing friction on the laundry, during the washing and drying process. A device of the kind above described is not subject to shrinkage as are cotton nets, and such a device has a much longer life and is capable of being readily repaired in case of damage. It has been found that laundry bags formed of a sheet of elastic netting may be more heavily loaded than the cotton bags thus resulting in a reduction in the number of sacks or bags necessary to be used for a given quantity of laundry. An elastic netting bag formed of rubber and the like is non-absorptive, resulting in a saving in the washing supplies and resulting in a saving of the power required to operate the laundry machinery. Various other advantages of my invention will be readily apparent to those skilled in the art.

While I have herein described the preferred forms of my invention, it will be understood that it is subject to variations and modifications without departing from the principle of the invention, and I desire that the patent to be granted hereon shall not be limited in any manner except as required by the prior art.

I claim as my invention:

1. A container in which laundry is adapted to be confined while being washed and dried consisting of a sack of elastic nonabsorbent and water-impervious material, said sack having a multiplicity of perforations formed in the sides thereof, and means for releasably locking the open end of the sack.

2. A container in which-laundry is adapted to be confined while being washed and dried, consisting of a sheet of water-impervious elastic rubber formed into a sack open at one end and having a multiplicity of apertures therethrough to'facilitate the entrance and exit of washing fluid.

3. A laundry container in which laundry is adapted to be confined during washing and drying, said container being formed of rubber providing a substantially smooth inner confining surface, said container having apertures formed in the sides thereof for the ingress and egress of a washing fluid.

1. A laundry container in which laundry is adapted to be confined during washing and drying, said container being formed of an elastic material impervious to water and providing a substantially smooth inner confining surface, said container having apertures formed in the sides thereof for the ingress and egress of a washing fluid.

5. A laundry container in which laundry is adapted to be confined during washing and drying, said container being formed of water-impervious rubber, said container being provided with apertures in the sides thereof for the ingress and egress of a washing fluid.

6. A laundry bag having side walls and a bottom, and being adapted to confine articles to be washed and dried, saidwalls being formed of sheet rubber providing substantially smooth article-confining sides, and having apertures formed therein for the ingress and egress of a washing fluid.
