Specification of Letters Patent.
Patented June 6, 1922.
Application filed January 6, 1921. Serial No. 435,419.
T 0 all whom 2'23 may concern:
Be it known that I, HARRY JosnPHsoN, acitizen of the United States, and resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Coal Bags, of which the following is a specification.
An object of this invention is to produce a noveland inexpensive coal bag of practical and durable construction that will be capable of withstanding, for a long period of time and without liability of becoining impaired, the ordinary strains of hard usage.
A further object is to provide a coal bag the body of which may be, in the; main, of usual construction, and the bottom of which consists of a plurality of slats, spaced from each other to allow proper drainage of the contents of the bag, and associated with the lower portion of said body insuch manner that it is impossible for the slats to become removed from the body under the most severe conditions of use.
Another object is'to provide a coal bag the spaced apart slats constituting the bottom of which are each composed of one or more metallic plates of proper construction (1) to support the contents of the bag at considerable distance from the bearing surface of said bottom in order that there can be'no interference with proper drainage of said'contents, and (2) to provide bearing surfaces of reduced area for said bottom in order that the coal bag can be dragged with but a minimum of friction.
A still further object is to provide in a coal bag of the present type, a bottom which is capable of being rolled.
With the above and other objects in view, the invention comprises the construction, arrangement and combination of parts now to be fully described and hereinafter specifi cally claimed.
In the accompanying drawing forming a part of this specification,
Fig. 1 is a perspective view of the improved coal bag, showing several of the slats of the bottom thereof removed.
Fig. 2 is avertical transverse sectional view thereof. i
Fig. 3 is an elevational view on an enlarged scale, showing a ribbed plate and a flat plate that may be associated with each other and with the body of the bag to form a slat for the bottom thereof.
Fig. 4 is a top plan view of the ribbed plate of Fig. 3, which may, by itself, constitute a slat.
Fig. 5 is an enlarged sectional view on line 5-5 in Fig. 4, and
Fig. 6 is a fragmentary perspective view, on a scale corresponding with Fig. 5, showing in detail an end portion of a ribbed plate.
The body of the bag, denoted by numeral 7, may be of canvas or other suitable mate .rial, and is preferably rectangular in horizontal cross-section, it having side walls 8 and end walls 9. The upper edges of the side and end walls are turned outwardly and stitched to the body, as denoted by numeral 10 in Fig. l, to add strength to the upper portion thereof. a
In preparing the body to receive its bottom, the lower edges of the side and end walls may be first turned inwardly for some considerable distance and then laid back upon the main body and stitched down-as indicated by numeral 11 in Fig. 2. The resulting folded over portions of said side and end. walls denoted by 12 and 13, respectively, provide a continuous flange forming the border of a restricted opening in'the bottom of said body, and it is to this border that the bottom of the bag is adapted to be secured. Adjacent ends of said folded over portions of the side and end walls may, if preferred,
end portions 13, and is arranged in the bottom of the body at about the longitudinal center thereof, and 16 denotes the usual handles for the body.
The bottom of the bag consists of a plurality of spaced apart slats, constructed as now to be described to permit proper drainage of the contents of the bag, secured to the continuous flange of the body in such manner that the slats cannot become removed from the body even under the most severe strains of the hardest usage. The slats are all duplicates ofeach other and may each consist of a ribbed plate 17 and a flat plate 18 associated with each other and with the material of the body, or each slat may con sist of a ribbed plate 1? alone. The slats extend transversely of the body and are designed to support the contents of the bag at considerable distance from the bearing surfaces for the bottom thereof to thus olfcr no interference to the proper drainage of said contents, and each slat is further designed to provide a bearing surface or reduced area to allow the bag to bcdraggcdi with but a minimum of friction.
The flat and ribbed plat-cs mentioned are preferably of metal. The flat plates are about the width of the body and when these plates are utilized they rest in the bottom of the body and against the flange defining the restricted opening. Holes 19 in the flat plates serve for the connection of the ribbed plates as will later be explained. The ribbed plates are preferably a trifle shorter than the width of the body and each ribbed plate has a smooth, level portion 20 and a ribbed or shaped portion 21 that nreiterably extends downwardly from about the central part of the smooth level portion and is of slightly shorter length than said smooth portion. Drain holes 22 in the ribbed portions perform an obvious function.
The ribbed plates are adapted to be fastened against the under face of the continuous flange of the body of the bag, and for this purpose I preferably provide the smooth, level portions of these plates with pointed lugs 23 adapted to pierce the material of said flange. Evidently, other securing means adapted to pass throngh the material of the continuous flange may be substituted for lugs 23. When the ribbed plates are utilized by themselves to constitute the slats of the bottom of the bag. the pointed lugs or other securing means, after being forced through the material of the continuous flange, are bent down against the upper face of said flange. hen the ribbed and flat plates are associated to pro vide the slats, the lugs or other securing means are passed through the holes of the flat plates and bent down against the upper faces of said flat plates. And. it will be apparent, a plurality of washers can be sub stit-uted for the flat plates, a single washer for each separate lug or other securin member of the ribbed plates. As shown, lugs 23 may also pass through strip of material 15 to be fastened down against the upper face of said strip or against a flat plate or washer arranged there-above. The intermediate lugs or other securing means of the end slats preferably pass through the ma terial of turned in portions 13 of the end walls, as will be understood.
By making the ribbed plates shorter than thewidth of the body of the bag, I preclude the possibility of the plat-es becoming engaged and torn loose when the bag. is being dragged and by providing said plates with downwardly extending ribbed or shaped portions, I provide bearing surfaces for the bottom of the bag adapted to sup port the contents of the bag at considerable distance from said bearing surfaces, as is evident. As is also evident, these bearing surfaces may be of any preferred dimension to better allow dragging of the bags.
By providing spaced apart slats between which are flexible connections, said connections comprising portions of the lower end of the body of the bag, the bottom of the bag is rendered foldable, and, as will be evident, the bags can consequently be rolled when not in use.
Any number of slats can be applied to the bottom of the body and the slats can be spaced any desired distances apart.
While I have shown and described one specific embodiment of the invention, it is to be understood that such changes in details of construction and arrangement of parts may be made as fall within the scope of the appended claims.
hat I desire to claim is:
1. A coal bag comprising a flexible body open at its lower end and a rollable bottom consisting of spaced apart, disconnected slats having. draining spaces therebetween, each of said slats being secured to said flexible body.
2. A coal bag comprising a flexible body consisting of side walls and open at its lower end, a rollable. bottom consisting of spaced apart, disconnected slats haying draining spaces therebetween, and means for separately securing each slat to the flexible body, whereby proper drainage of the bag is provided for.
3. A coal bag comprising a flexible body open at its lower end, and a rollable bottom adapted to be secured to the lower portion of said body. said bottom consisting of spaced apart, disconnected slats eachcomprising a plate having a downwardly extending rib, and said ribs being of such co11- struction that the bearing surfaces for said bottom are of reduced area for the purpose specified.
4. A coal bag comprising a flexible body open at its lower end, and a rollable bottom adapted to be secured. to said body, said bottom consisting of spaced apart, disconnected slats each comprising a ribbed plate and a. flat plate secured to each other and to said body.
5. A coal bag comprising a body shaped at its lower end to produce a continuous flange providing a restricted opening, and a foldable bottom consisting of spaced apart disconnected slats each comprising a ribbed plate and a flat plate secured to each other and to said flange, said flange being gripped between said plates.
6. A coal bag comprising a body having side and end Walls of flexible material shaped at their lower ends to produce a continuous flange providing a restricted opening, a bottom consisting of spaced apart disconnected slats each comprising a flat plate adapted to rest against said flange and above said restricted opening and a ribbed plate adapted to rest against said flange and beneath said opening, and means for fastening said flat and ribbed plates to each other, said means adapted to pass through the material of said flange. 4
7. A coal bag comprising a body shaped at its lower end to produce a continuous flange providing a restricted opening, a bottom consisting of s aced apart disconnected slats, the ends of W ich are attached to said flange, and a flexible strip extending across said bottom and transversely of said slats, said strip constituting additional means for securing said slats to said body.
