To all whom it may concern: e 4 Y Beit known that I, CLAUDE- Rnns, `a citizen ofthe United States, and a resident the Icity and countyof San Francisco, State of California, haveh invented a certain 4new and useiul Charger, of which the fol'owing 1s a specliiciation.

The device of: my. invention is used for inl troducing `material intovv afeonduit' ,through whichuid under pressureis passingxf The:

fiuidis usually' air whichisfusedto convey' th `material thronghthe conduitto a remetel loint.Y henjtheconduit'isfof great length] a- ,highpressure blower @must he' employed for forcing. th,- .air .through the conduit .and` these blowers are `Of .Such construction 'that it',v is not possible'to fee'd'the iraterial through" the: blower, and consequent Athe .material must heeentered into the `conduit through which lthe air ,n under lprassure,` is" passing'. Thel airis delivered by ythe high'p'resstire blower into the` receiver 3 in; which: the f in 'ijoulsesf are smoothed outu and the air ps assesy kfrom vthe receivery lthrough the con` which ispreierahly `cylindricad in form and whichis closed atvthe sides. by the vplates 8.

Journalled infthe Vplatesl 8f ashaft 9' to duitzt.. The conduit 4 isprovided with a; `l' 5 which has anI upwardly Adirected opening' which is secured a pocket wheel 12. The shaft is rotatedV by any suitable means such as the electric motor 13 Whichis connected to the shaft through a suitable gearingvM. The casing 7 is provided on its upper' side with an inlet opening 15 which is in cominunication with the discharge spout 16 of a superposed hopper, in which the material p0 be1 introduced into the conduit is accumuatec.

it may consist of any other material which it is desired to introduce into the conduit.

The pocket wheel 12 is preferably closed at the sides by the walls 17-18 and is open at its periphery. The pocket wheel is provided with a series of pockets 19 deiined by the walls 21 extending` from the hub to the periphery of the wheel. The material is introduced into these pockets through the inlet opening 15 and, by the rotation of the Wheel, the charged pocket is moved to a p position over the discharge outlet 22 of the casingA and the material is discharged into the T 5. Means are provided for introducing air under pressure into the bottom of the pockets immediately before they open to the discharge outlet 22 to facilitate the discharge of the material from the pockets. This means preferably comprises a second series of pockets 23 in the pocket wheel, the

two series of pockets being separated bythe intermediate wall 2i. 'The pocket are defined by walls 25 extending from the hub of the wheel to its periphery. K c c The series of pockets 19 are connected to gether in pairs with the series of pockets 23, one pocket 19 and onepocket forming a pair. The pocket 2B of eachpairleads the pocket 19 so that advance of the pocket 19. Azrraiigedlin thecasing 7, in alignment with the `intermediate wall 2&1 is an annular wall 2G, and arranged in alignment with this wall 26 and extending kdownwardly into the T 5 is a bai-He wall 27 whichseives to direct air from 4, upwardly into the pocket 23,as these the conduit pockets, successively register with the dis* charge loutlet 22. ,Y l i The series of pockets 19 arev conncctedttogetlier in Apairs with the series'of pockets 23 by apertures 28 extending through the inten mediate wall 2e at the bottoms of 'the pockets.` As the pocket wheel 12 rotates, a pocket 23 of one pair moves yinto communication with the discharge outlet 22 inradvanceiof the other pocket 19 of the pair. Air under. pressure is then introduced into the pocket 23 and this air passes through the opening 28 into the associated pocket 19, at the bottom of the charge of material therein, loos` ens this charge of material and places it under a pressure which is equal to or greater than the pressure to which the pocket 19' This material usually consists of VWood shavings, sawdust and chips, although Y the pocket v253 comes in communication withthe outlet opening 22 in will be exposed when such pocket reaches the discharge outlet 22. Consequently,as soon as the pocket 19, which carries the material, reaches the discharge outlet 22, the material in the pocket falls by gravity through the discharge outletinto the T 5. The pockets 19 are much wider than the pockets 23 and, while the pockets 23 may receive some material at the inletopening 15, this material is-blown through the opening 28 into the corresponding pocket 19, when the pocket 23 is exposed at the discharge outlet 22, so that all of the'material is readily discharged from the pockets as the wheel rotates. By placing the material iii the pocket under a pressure substantially equal to the pressure which exists inthe conduit, before the pocket comes into communication with thecoiiduit, the liability of the material being packed into the bottom of the pocket by the pressure of air entering the opening ofthe pocket is eliminated and all of the material is discharged from the pocket during the time that it is in communication with the discharge outlet.
