JOHN S. SOULLY, OF PITTSBURG, PENNSYLVANIA;

COAL-BAG.

SPECIFICATION forming part of Letters Patent No. 637,673, elatedV November 2i, ieee. Application iiled March 6. 189g. Serial No. 707,827. (No model.)

T0 all whom it may concern.-

Be it known that I, JOHN S. SoUnLY, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered a new and useful Improvement in Coal-Bags, of which the following is a full, clear, and exact description, reference being had tothe accompanying drawings, forming part of this specification, in which- Figure lis a perspective View showing a number of bags in the operation of loading. Fig. 2 is a perspective view of my improved coal-bag in position for filling. ig. 3 is a similar. view showing the bag filled and closed at the top. Fig. 4 is a view similar to Fig. l, but inverted, illustrating the method of discharging or emptying the bag. Fig. 5 is a detail sectional view illustrating the method of constructing the bottom. Fig. 6 is a similar view illustrating the modified construction.

Myinvention consists of an improved basket or bag for packing and transporting coal, grain, or other minerals or material, and it is particularly adapted to be used in loading coal in large quantities to and from vessels and for packing and storing it therein.

Referring to the drawings, the main body portion of the bag consists of a surrounding preferably cylindrical shell 2, made of wovenwire netting or other suitable flexible material, the lower portion of which is closed either by weaving the wire continuously around, so as to form a bottom, or by joining the sides to 3 5 .and incorporating them with the circular reinforcing-base 3 in any suitable mannen` It is obvious that other forms may be employed instead of the circular-as, for instance, a square box-or the sides may, if desired, be rigid, with iexible securing devices at the top, and within the scope of my invention I may employ any suitable fabric, as canvas, jute, sacking, dto.

It is desirable to employ the reinforcingbase 3 and to make it of a substantial and durable material, as Wood, plate iron or steel, as the entire Weight of the contents of the bag is sustained upon such bottom by means of the central support 4, which may be a rod, cable, chain, or rope, as desired. This central support passes through the bottom at its center and is firmly and securelyinco'rporated with it in any convenient manner, so as to be firmly attached and secured against removal in either direction. This may be accomplished in the case of a cable by making knots 5 at each side of the bottom.

In Fig. 6 I have shown a concave bottom 3', Which-may be used with good results, and also a supplemental washer 6, to the periphery of which the Wires of the bag may be secured. The central support 4, as will be seen, projects somewhat above the top of the bag and also forashort distance downwardly below the base, and each extremity is furnished with an eye or loop 7, by which the bag may be suspended upon a hook while loading or in lifting by a crane in either the loaded or the inverted position. The upper edge of the bag is furnished with a series of free extremities 8, each terminating in an eye 9, through which is drawn a tying-wire 10, by which the upper end of Athe bag is securely closed, so as to prevent exit of its contents, by drawing the wire extremities tightly and closely around the central support and securing them as in Fig. 3. Other means of securing the top may be employed, it' desired, the object being not only to close the top of the receptacle, but to firmly attach such top to the central support-as, for instance, by wrapping, thus centralizing the load and insuring equilibrium. When the bag is filled with coal and thus closed, the contents may be readily lifted by a crane-hook and deposited in any desired location. If it is desired to discharge the contents atsuch point,the cranehook is inserted through the eye 7 at the bottom of the bag and the bottom is raised, when the contents will burst open the retainingwire 9, or it may be previously cut, when the bag maybe lifted away from the coal and removed.

The advantages of my invention willbe appreciated by those consuming or transporting coal in large quantities-as, for instance, on sea-going vessels, where the coal may be loaded into the hold in an expeditious manner and securely packed and retained in position, if desired, by lashing it down, thus insuring against listing. Also when loaded upon an open deck it is not liable to be Washed sure against breaking or loss, although the -1 andmay be used a number of times.

lateral pressure exerted will not be proportionately great, and the entire strain will fall upon .the bottom and be ,carried by'the central support. vanized, and when properly made the bags will withstandconsiderable rough treatment Owing, however, to their cheapness of construction the bagsv may be dispensed with or thrown overboard when empty. Y

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. Abag for transporting coal, duc. ,comprising a central-sustaining member projecting above the upper portion of the body of the bag, and a surrounding body portion having its bottom secured to said central member and extending upwardly and provided with means at its upper end whereby it may b e gathered in and secured closely around the central sustaining member to form a top which will prevent exit of the contents of the bag at such point during transportation.

2. Abag for transporting coal,&c., comprising a central sustaining member projecting above the upper portion of the body of the bag, and a surrounding body portion formed of exible material having its bottom secured to said central member and extending upwardly and-provided with means at its upper end whereby it may be y gathered in and secured closely around the central sustaining member to form a top which willprevent exit of the contents of the bag at such point during transportation.

3. A bag for transpcrtingcoahdnc., comprising a central sustaining member projecting above the upper portion of the body of the bag and having a loop at its upper end, and a surrounding body portion havin g its bottom secured to said central sustaining member and extending upwardly and provided with meansat its. upper end whereby it may be gathered in and securedclosely around the central sustainin g member to form a top which will prevent exit of the contents of the bag at such point during transportation.

These parts arepreferably gal- 4. A bag for transporting coal, (itc. comprisi ing av central sustaining member projecting above the top ofthe body of the bag and having aloop at its upper end; aV surrounding body portion having its bottom secured to said central sustaining member and extending upwardly and provided with means for securing it at the top around the central sustaining member to prevent exit of the contents of the bag at such point during transportation; and means at vthe bottom of the bag whereby it may be sustained in an inverted position. Y

5. Abag fortransportingcoal,&c.,compris= Ving a central sustaining member projecting above the top of the body of the bag and having a' loop at its upper end; va surrounding body portion having its bottom secured to said central sustaining member and'extending upwardly and provided with means for securing it at the top around the central sustaining member to preventexit of the contents'otl thebag at such point during transportation; and a member extending` downwardly from the bottom of the bag and provided with a loop.

6. AAbag for transporting coal, &c., having a circular base, an upwardly-extending cylindrical body portion of wire-netting secured to the base, a central sustaining member secured to the. base at the center, extending downwardly from the base and upwardly above the top of the bag and provided at each end with a loop, and means for securing together the body portion at the vtop closely around the central sustaining member to prevent exit of the contents of the bag at such point during transportation.

'7 A bag for transporting coal, &c., comprising a central sustaining member projecting above the top of the body of the bag and having a loop at its upper end, a surrounding body portion having its bottom secured to said central sustaining member and extending upwardly and provided with a series of loops or eyes at its end, a cord or wire passing through said loops whereby the top ofthe body portion may be gathered in and secured around the central sustaining member to prevent exit of the contents of the bag at suchpoint during transportationg'and a member extending downwardly from the bottom of the bag and provided with a loop.

In testimony whereof I have Vhereunto set my hand.
