The invention consists, essentially, in a drier having a special table or platform which supports the stock While drying. This table or platform consists, in brief, of a longitudinal series of transversely-extending shelves Which. are comprised in groups or sets, 3, .3, etc., and l, 4, etc., with those of one group or set alternated vvlth. those of another, the said shelves having combined thereivlth means for causing movement of the shelves WidthWise back and forth length- Wise of the table or platform relative to one another whereby those of a given group or.

uthey slip in under the layer of material. lfig. (5 1s a plan vlew of 901301111011 of one direction ofthe length of the series or table;

. so that the effect of successive reciprocating movements is to shiftthe layerof :material graduallyalongfithe table; or platform from the receiving end thereof to the discharging uendtl'iereof. llnbeing thus shifted along,

thestoch is subjected to an agitation-from beneath, due to the. Working of thei movable shelves underneath ithe layen of material, producing a movement; Of the particles of the general mass among "themselves; Inad 1 dition, the stool; continually is being separated from thesurfaces of theshelves. Thus, astheunovable shelves inovegfromtheir pro- 1 jected position inthertop table or platform which they 65 ..-:in Riga; 3Mtoivardutl1eirdetracted position in the middle table or platform in said figure table or platform, toward their projected position, as in the first table or platform,

they slip in between the layer of stock and the stationary shelves, lifting the said layer from the stationary shelves. As the layer is partly carried and partly pushed along the stationary shelves in this returning or advancing. movement of the movable shelves, portions of it fall from one stationary shelf upon the next succeeding moving shelf, throughout the table or platform. The action hasthe important efiect of producing a succession of changes in the position of the stock, involving agitation and turning of the latter so that every particle thereof is presented frequently to the circulating currents of air within the drier, insuring vaporization of any moisture with which the stock maybe charged and thereby rendering the vaporization, and consequently the drying, more rapid. The drier is furnished with means of inducing the drying of the stock while the latter rests upon and is being advanced along the table or platform. Such means consists, preferably, in means for causing an upward flow of heated air within the casing containing the table or platform as the action just referred to proceeds. At the time of the reverse movement of the lovable plates, the withdrawal of the latter in among the stationary shelves leaves openings under the stock adjacent the edges of the stationary shelves, facilitating the air movement. Preferably, perforations are provided in the different shelves as illustrated in Fig. 6, in which some of the perforations in a shelf are shown so that the heated air may pass upward therethrough, in addition to finding passageway at the leading edges of the different shelves where the material hangs down from one shelf to the next. Movement of the 1 air upward through the shelves and the stock has the advantages of preventing the stock from adhering to the surfaces of the shelves, and loosens or lofts the stock, without any tendency to mat or pack.

A single table or platform comprising shelves such as just described. and operating to feed the stock in one direction within the drier may be sutlicient to effect the required drying in some cases. Usually, as in Fig. 3, one such table or platform is arranged to deliver or discharge upon another'like table or platform below the same, such second table or platform being arranged to feed the stock in the reverse direction while under going the like treatment, and to deliver or discharge the stock upon a third table or platform below the second and feeding in the same direction as the first. Additional ones may be employed, if desired, in erder to extend the treatment to the extent desired. In falling from the discharge or delivery end of one table or platforn'i to the next table 'or platform below the stock becomes turned over, and this turning over of the stock is repeated each time the stock drops from one table or platform to another. The final table or platform discharges from the machine through av suitable outlet 2.).

The stock to be dried may be applied by hand to the receiving end of the first table or platform, but Fig. 1 shows an automatic feeder 2 having a hopper, and 'l'urnished with an elevating belt or creeper 2 and a transfer cylinder or like device 2", for delivering the stock at K, Fig. 1-3. so that it falls upon the said receiving end.

The general assemblage of shelves comprising a table or platform is shown as extended horizontally so that the table or platform is horizontal from one end thereof to the other, although it is to he understood that a strictly horizontal arrangement of the table or platform i not necessary. The stationary shelves :3, 2%, are mounted on suitable supports in connection with the casing 1, and in order to permit a movable shelf to work in and out between one stationary shelf and the next a vertical opening is left between the adjacent edges of one stationary shelf and the next. This vertical opening is provided for in the present instance by inclining the stationary shelves upwardly and frn-wardly. so that the said adjacent edges are separated vertically from each other. The movable shelves 4-, etc., which alternate with the stationary shelves work in these openings and are similarly inclined. As thus arranged. and combined the parts constitute a stepped alternating succession of transversely-extending stationary shelves and movable shelves.

Stock supplied at the point X, Fig. 3, upon the receiving end of the top table or platform, either by being thrown by an attendant into the space above said receiving end or deliv red thereinto by an automatic feeder, will rest upon the exposed portions of the shelves at that end. In Fig. 3 the movable shelves 4, 4:, are at the extreme of their movement toward the right so that stock supplied as just referred to will lie. chiefly upon the top surfaces of the movable shelves at such end. As the said movable shelves are drawn toward the left they will slip out from under the stock. which will settle down upon the top surfaces of the adjacent stationary shelves 3. 3. As the movable shelves, after having moved to the full extent toward the left, are returned toward the right the leading edges of those which are located at the receiving end will push portions of the stock. forward from.

a meat 71 the said adjacent stationary shelves on to the movable shelves next. toward the right.

Toward the final portion of the movement toward the right the stoclr will be largely ment will almost completely cover and concoal the stationary shelves over which they have been moved, as 111 Fig. 3. Then as the movable shelves move toward the left regain they will draw out from under thelayer of stock, permitting such layer tosettle down.

again upon the stationary shelves; lContinuanee ofthe action. will workthestock gradually from the receiving end of the table or platform toward the discharging end thereof, and cause it to discharge-from the latter end, and solong as the supply is maintained at X a continuous layer of stock will extend along),' the table or platform, from the receiving end thereof to the dis charging end. When the various shelves are perforated for the passage of air, as preferred, and provision is made for an upward flow of air within the casing, the air will pass upward through the }')Gl'f0l'tlll011S and into and through the layer of stock, fully permeating the latter, and in escaping from the top of the latter will, carry off the vaporized moisture.

The means for operating the movable shelves may vary in practice. ln the present instance every movable sl' lf of a table or platform, at eachend thereof, is pivotally connected at to a post or standard 6 carried by a slide-bar 7 extending the length of the table or platform and serving to join together the entire series of movable shelves pertaining; to the latter. Thetwo slide-bars t, 'Z, ofeach table or platform are rec1pro cated by means of 'acks 8, thmade fast to them and engaged by toothed sector-s9, 9,

on a transversely extending roclrshaft 10. The rock shaft 10 is rocked through suitable power-connections. la the present in stance the rockshaft 10 of each table or plat form is provided with an arm 11, the arms of the three rockshafts being connected together by alink or links 12, and another arm 11 of one of the said rockshafts con nected by means of a connectlng rod 13 to.

an actuating crank ll carried by a wormgear 15 which 153 engaged by a worm upon the'shaft of a stepq'iulley 16. The

sljidebars

7, 7, are guided to move baclr and forth in an oblique direct on correspotuling withthe obliquity or inclination of the stationary shelves 3,

3, by means of inclined shoes 17, 17, 17, carried by the slide-bars and working; upon brackets '18, 18, having; lnclined supporting or guide-surfacesyas shown best in ll igs. 3 and 4. The said brackets are mounted upon convenient fixed supportsfh), 20,

At the delivery end of the top platform in Fig. a guide or deflector 121. is mounted in position where it will properly guide the stock, as it falls from the said deliveiyend, platform below, a. lilro guide/E151 being located at the delivery end of the second platform in position to guide the stock on to the receiving end of the third ola tform. In this instance the third platform delivers or discharges out through an. outlet in the right-hand end of the casing.

Suitable circulation fans :23 (Fig.2) are located in anaumliarv chamber or chambers at oneside of the chamber containing; the tables or platforms, and in conjunction with the said fans steam coils :25 are provided in the i said auxiliary chamber or chambers. ltach of the circulation fans has its actuating pulley Han outlet 26 for the escape of the n'ioistinre-surchurged air is provided at the top of the casing, as shown inv Fig. l. To prevent the stock from being dragged 1n between the stationary shelves andthe moving ones by the baclr and forth movemen t of the latter, guard-

strips

27, 27, Fig. t, are mounted. in connection with the leading edges o f a ll the said slu zlves.

A drier having means for inducing drying, and a horizontal stock-supporting and feeding table upon which the stock rests while being dried, the said table comprising transverse shelves which alternately are fixed and movable, and actuating mechanism by which the movable shelves are reciprocated widthwise and thereby alternately drawn in under the fixed shelves so as to withdraw from the layer of stock which is being operated upon, leaving the latter resting upon the series of fixed sections, and

i then are advanced out from under the fixed sections so as to take the said layer upon their own upper surfaces, lifting it as well as pushing it forward upon the fixed shelves.

30. A drier having means for inducing drying, and a horizontal stock-supporting and feeding table upon which the stock rests while being dried, the said table consisting of a series of transverse shelves comprised in groups or sets with those of one group or set alternated with those of another, and actuating mechanism for producing relative reciprocating widthwise movement by which the shelves of one group or set are alternately drawn in under those of the other group orset so as to withdraw from the layer of stock which is being operated upon, leaving the latter resting upon the other shelves, and then are advanced so as to take the said layer upon their own surfaces, lifting it as well as pushing it forward.

31. A drier having a horizontal stock-supporting and feedmg table, and means for causmg an upward flow of air through the Copies of this patent may be obtained for table or platform and the stock resting thereon, the said table consisting of a series of transverse shelves respectively having openings for the passage of air therethrough and comprised in groups or sets with those of one group or set alternated with those of another, and actuating mechanism for producing relative reciprocating widthwise movement by which the shelves of one group or set are alternately d "awn in under those of the other group or set so as to withdraw from the layer of stock which is being operated upon, leaving the latter resting upon the other shelves, and then are advanced so as to take the said layer upon their own surfaces, lifting it as well as pushing it forward.

32. A drier comprising, essentially, means for inducing the drying, and a table or platform which supports the stock while drying as well as feeds it along, the said table or platform consisting of a horizontally extending longitudinal series of transverselyextending shelves which are comprised in groups or sets, with those of one group or set alternated with those of another, and having combined therewith means for causing relative movement of the shelves widthwise back and forth lengthwise of the table or platform, whereby those of a given group or set alternately are covered by those of another group or set, and vice versa.

33. A drier comprising essentially, means for causing an upward current of air, and a table or platform which supports the stock while drying as well as feeds it along the said table or platform consisting of a horizontally extending longitudinal series of transversely-extending shelves having openings for passage of air and comprised in groups or sets, with those of one group or set alternated with those of another, and having combined therewith means for causing relative movement of the shelves widthwise back and forth lengthwise of the table or platform, whereby those of a given group or set alternately are covered by those of another group or set, and vice versa.

In testimony whereof I aflix my signature in presence of two witnesses.
