CHARGING DEVICE.

Specification of Letters Patent.

Application filed December 24, 1909. Serial 'No. 534,864.

To all whom 'it may concern:

Be it known that I, CHARLES W. LUMMIs, a. citizen of the United States, and a, resident of Camden, Camden county, New Jersey, invented certain Improvements in Charging Devices, of which the following is a specification.

My invention relates to means for feeding coal or other material to gas producers,- cupola furnaces and structures of a similar character, and the object of my invention'is to provide means for insuring aneven feedterial.

The usual method of feeding coal togas producers, furnaces and the like, is to provide a magazine or hopper, which may be and distribution of the fuel or other macontinuously rotatable or havea rotatable bottom into which the coal is fed and from which the coal is discharged, with a suitable distributing device carried by or cotiperating with the magazine or hopper initially receiving the coal. It hasbeen proposed heretofore to provide means forefl'ectingan even feed and distribution of the fuel, but

in prior instances it has been necessary to provide coal of special and uniform size to effect such even feeding.

The objectof my invention is to provide means for effecting an even feed and disreadily operated and available for-use with coal of any size within reasonable limits.

These and otherfeatures forming the subject of my invention will be fully pointed 1 out hereinafter, reference being had to the accompanying drawings, in which: A Figure 1, is a sectional elevation of a feed device for, furnaces, gas producers aiid the like, embodying my invention; Fig. 2, is an enlarged plan view of the distributer employed in connection with my lmproved feed device; Fig. 3, is a sectional view of the distributer on the line a a, Fig. 2; Figs. 4: and 5, are transverse sectional views on'the lines 'bb" and c-c, respectively, Fig. 2; Flg. 6, 1s a front elevation of one element 9f the distributing member; F1g.'7, 1s a sectional 0 p I a I I plan vlew on the llne d.{l, Flg. 1-; 1 1g. 8.

is a sectional view similar to Fig.1 illusy trating another form of structure Il'lb()(lylug my invention, and Figs. 9 andlO, are,

respectively, a sectional elevation and plan view of a device tributing element.

In the drawings herewith, 1 represents a magazine or hopper for the reception of fuel or other material introduced at the top of the same; such magazine being provided with a rotatable cover 2, to close or open the top. of the hopper. The magazine or hopper carries a bracket 4 receiving a bushing 5 which is mounted for rotation in said Patented Feb. 21, 1911.

bracket and through said bushing a ver-- tically movable shaft 6 passes; said shaft being splined thereto by a feat-her 7 in order that it may be oscillated by movement imparted to said bushing simultaneously with its vertical movement. The lower end of the shaft 6 carries a conical distributing member 8 of a special character, which may be connected to the shaft by links 9. The magazine or hopper has a contracted outlet 10 and the distributing members is preferably provided with an annular surface 11 for contact with the lower edge 12 of said contracted outlet.

At the upper end of the shaft a thrust bearing 13 is provided for engagement with a collar 14 in which the end of the shaft- 1s free to rotate, such collar being arranged to impart positive movement to the shaft when actuated in a vertical direction. The shaft. is maintained in the raised position "with the distributingelement closed against the'lower mouth of the-hopper by means of aweighted lever 15. t-runnioned'to-said collar at 116 and fulcrumed at 17 to a link 18 pi-votally connected at 19 to the bracket #1: said lever 15 having a handle 20 whereby it maj be actuated. The bushing journaled in the bracket 4 is provided with a handle 21 whereby movement may be imparted to theshaft. 6 by the operator; such movement being simultaneous with the lowering of the conical distributer carried by said shaft.

The conical distributer is of a novel construction, and inaddition to having means for throwing the material from its upper surface due tothe centrifugal action imparted to it by rocking the handle 21, it has-apertures 22 through which a portion of the coal may bedischarged and an irreguimmargin with portions successively de-.

creasing in radial length. The apertures 22 are providedw1th a circumferential wall 23. and side walls 24- which form ribs eX- vided with vanes or blades 25 of different same character, as those indicated 'ried by a vertically dimensions disposed on its upper surface, which are designed to divert the coal or other material as said member is rocked and as such material is dropped from thedistributer in a series of concentric paths it is caused to spread in a-subst-antially even layer in the gasproducer or furnace.

The structure shown in Fig. 8 is of subtantially the same character as that shown in Fig. 1, except that provision is made for water cooling the same throughout; the distributing member being also water cooled. For this, purpose, the distributing member is made hollow, as shown at 26, and is carmovable hollow shaft 2-7 which may be actuated by means of the in Fig. 1, to lower the distributing memberand oscillate the same. The hollow shaft carrying the distributing member is provided with a cu 30 atits upper end into which a cooling fluid ma .be introduced from a pipe 31, suitably va ved at 32. From the cup 30 such fluid may pass to the" hollow distributing member through a tube 33. As the distributing member fills, the fluid risesin the hollow shaft outside the tube 33 and may pass to a chamber 34' near the upper end of said shaft. and from said chamber the fluid may overflow through a pi e 35 into a small annular tank 36 suitably supported by the bracket 4:.' From this tank, the'fluid may overflow through apipe 37 into a tank38 surrounding the lower portion of the hopper or magazine, and from the latter it may overflow through a pipe 39 to a water receptacle 40 on top of thegas producer or fornace.

I trated in Figs. -1 and '8, or

. The magazine or hopper may be agitated by the handle 21 connected to'the bushing 5 through which the shaft slides, as illus- I may provide a structure such as shown in consisting of a lever 41 with a pawl 42 for engagement witha ratchet 43 so as to im-.

part a continu'ously'rotative movement to the shaft G-and thence to the hopper from the intermittent doscillating movements of the lever 4:1.- The shaft is splined to the bushing, and the ratchet wheel may be keyed to the bushing, but in this instance these parts are in one piece, and the lever is journaled on the bushing.
