Raw sugar reaches the refinery in bags.

It comes frequently in very large quantities, on the Atlantic coast often in cargo lots on steamships.

fineries is to store this sugar in bulk in large bins, removing it from the bags before storing it. From the bins it is withdrawn as needed for the processes of refining. Usually the raw sugar bins are placed above the ground floor of the refinery. The place of unloading of the bags from the ship or car is generally at quite a distance from the bins. Heretofore these bags containing the raw sugar were carried by travelling cranes or 1 even by hand trucks to the mouth of a bin. The cord closing the mouth of the bags was cut by hand, and the bags lifted by main strength and emptied into the bin. The bags, which are customarily of a few standard sizes are all heavy, and the work of lifting them is exhausting and slow, and required many hands. Men frequently broke down when employed at this work.

By my device the bags are received by my 25 conveyer first on a feeding apron, that is power driven but the movement of which is under the control of an operator who can stop or cause it to move independently of the movement of a main conveying apron, which is normally in continuous movement. This feeding apron furnishes means for distributing the bags singly or in convenient groupings along the main apron and is located at a convenient place in practice near the repose. The bags usually'must be deposited on the feeding apron in irregular heaps, and as the conveyer will work more ehiciently when the bags are distributed along the main apron fairly evenly, the value of the feeding apron is apparent. The main apron carries the bags that it receives from the-feeding apron to the vicinity of the bins, and, near this point, the bags are gripped near their bottoms by movable carriers, while the bags are lying on the main apron,and are drawn over a downwardly inclined surface where upon the bottom of bag is lifted gradually by the carriers, the sugar being emptied from each bag as its bottom is lifted, until the bag The practice prevailing at re-' ceiving end of the main apron for this pur-- is emptied. The empty bag can then be disengaged from the carrier. This inclined surface is furnished, in practice, by an auxiliary apron placed adjacent to the main belt. This auxiliary apron can form the bottom of an inclined chute down which the sugar will flow. The discharged sugar passes down the inclined apron. This arrangement of the inclined apron and bag carriers obviates the jarring that otherwise would happen, were the bags weight thrown upon the bag carriers suddenly at the discharge end of the main apron. The conveyer substitutes ma chine work for the heavy labor of unloading and hastens the carrying and storage of raw sugar and obviates considerable crude, expensive and dangerous agencies like the long distance traveling cranes, and the labor required to be performed manually with it in use is directive, the hardest labor being occasional manual adjustment of the bags upon the main apron, which is many times easier than lifting the bags.

The endless apron, 1, carries thebags of raw sugar from a point convenient to the ship or car to a point near the bin. To distribute them on this apron I use a feeding apron, 3, upon which the bags are placed. Its oischarge is upon the apron, 1. The mecha- I nism driving the apron, 3, isunderthe control of an operator who regulatesitsdriving mechanism by means, for nstance, of an electric switch 96 sothat,n o matter how lrregularly the bags are pla ced on the apron,-3,-they can be discharged uponthe apron, 1, so that, they will be distributed su'ficiently evenly on it to betaken care 'ctby the automatic bag 7 unptier. The apron, 3,1s dr1ven,1npract1ce, y.;an1electr1c mot0r, 25that;.1s undenthecon- I trol ofthe;operator'andicanbe started, and stopped and its speed regulated by him. This motor drives the belt 3, through the worm,

v.39,.and,thegge'ar wheel, '27, and is carriediby J thepulleys, 24, and 26. The aprons, 1, travels continuously ata regular speed and 1S supported at intervals asby the rollers-2, 2. The

driving pulley, isconveniently placed at 't's dischargeaand an idler, 5, canbeused-to i'ceeptheapron, 1,Itant andthe apron can be 7 kept clean by-the revolving brush,l19. H

The receivingv end of the inclined auxiliary apron, 30, is elevated-toa height preferably only slightlybelow the level of the apron, 1,

its discharge .iThc sid guides, 3 keep the sugar dischargedfromthebags from going on the side of-theapron, 3,0. In practice, is an electric motor with a shaft,'ca rryin aworm, '83, meshing with the gear,-84,

drivingthe pulley, 4, and the main apron,

1, and also the sprocket wheel, 81; from which the chain, -86,;the sprocketwheel, 85,

and the pulley, 33, drive the inclined auXil- N iary apron, 30. Theupper or receiving-end ofthelapron, 30,is carried by: the small 31 01181, 9. f i N, j c

The ;automatic bag emptier, is composed of a number of bag carriers, 10,-which are oined together in an endless series of flexible connections, 15, and move along a closed circuit onthe track, 12,'on trolley,-11 the springs p cuit continuously bringing disengaged bag hold the devices for catching the bags well above them asthey pass along onthemain I apron, 1; unyielding connections, that are slackened by the pull of the spring, 7, when the carrier isnot drawn down by the Weight ofthe bag" or by the attendant (see Fig.5)

limit the distance the devices for catching the bags can be separated fromthe rest of the "bag carrier (see Fig. 9;) 1 In practice, the hanger, 71, has acha in, 90, which goes to a holder, 91, from which a series of chains, 16,

long enough to allow the hooks, 13, "to be" pulled down and insertedin the bags as they pass along on the apron, 1, .exten'dto ,the

trolleys and hanger is .illustrated especially in Fig. .7 in which a yoke composed of the arms, 73, and carries the pulleys, 11, 11,

that run on the inner side of the flange, 72, which is carried from thefiange, 74, by the web, 7,6,.the loop, 7 0, serves conveniently to secure the end of the chain forming the flex- -1ble connectionsbetween the bag carriers.

I .findit very advantageous to. form the bus, 14-(see zFigs. 5,and 6,.especially) of a rigid backpiece, 530, having;loops, '58, for

the supporting chains, 55, and 53, and a more flexible (piece, formed of strongleather or other. suitable-substance, to which are secured thehooks, 13. I .A'pair ofturrets, 175, (see :Eigs. 11 and With radially projecting sprockets, 1172,
