Application =filed Juliet), 1923. Serial No. 644573.
To all whom it may concern:
Be it known that I, JAMns ALBERT Hose, a citizen of the United States,residing [at Lowell, in the county of IMiddleseX and State of hiassachusetts, have invented a new and useful Drier, of which the following is a specification.
'l his invcntion relates to a drier capable of general use but particularly for drying fibrousniaterials such as wool, cotton and the like. The principal object of theinvention is to provide for increasingthe drying capacity of a machine of this kind and improving the product by. subjecting the material to a preliminary. drying operation, and .the
modificationof the drier to ,permit of the location of the feeding device within the drying chamber, or in such close communi cationtherewith that the-heated :air currents from-.the,drier .-proper will permeate the fibrous material while being ,fed forward t ward the drying apron. Further objects and (advantages of the invention will appear hereinafter.
Reference is to be-had ing drawings in which Fig. 1 is a side elevation of a wool drying machine constructed in accordance with this invention;
Fig. 2 is a plan of a portion of the same on enlarged scale;
Fig. 3 is a longitudinal sectional view on the line 3-3 of Fig. 2; and
Fig. 4 is a transverse sectional view on the line 44.- of Fig. 2.
I have shown the invention as applied. to a well. known type of wool drying machine involving a casing 10, drying apron 11 on which the material is conducted through the machine, and coils 2-8 of steam pipes arranged at different places with blowers 14 for circulating the air. This machine of course has other features, some indicated in the drawings, but not specifically described herein because they do not constitute part of this invention, and because the invention is capable of being used without them.
IIeretofore it has been customary to provide a separate automatic feeding machine set up at the intake end of the drier for loosening up the material and continuously feeding it on the drier apron in a loose state. ".lhis material of course is laden with to the accompanymoisture and the drying does :not commence to take effect'rin the old machines until the material is deposited by the feeding device on the apron. i
In this invention-d extendthe side walls of the casing 10 rearwardly far enough to enclose the automatic feeding machine and provide the extended end with a door 15 through which the material can be dumped in as appears through the :glass panel 16 -in Fig. 1-, and I also preferably provide :an inlet pipe or opening .17 through-whichthe material can beffed in by a blowing system or conveyor fso that the material can be introducedin 'eithenof these-ways if. desired.
Inside this end of the machine is a feeding device comprising a horizontal endless apron .20 on wlriclrtihe. material =i's:-=tle-1:iosited and incl-inedfeeding apion-. 21-: located adjacentithereto at the lower. end {for taking the materiailnp over the upper-.lroll and past the 00mb r22. i. "Ihis: draws the mlttelifiil up over; the upper mollngainst itherusual beater 23 1- and .it .iis edeposited on the apron '11 .in
frontjiofthelbafi le pleitefl. 1. I 'Theseapairtsi just described are roperated in any desired way by power and are located within the casing 10 at the end of the apron 11 as indicated. I have illustrated one kind of automatic feed, but this invention is not limited to that particular type of feeding device.
The casing can be extended upwardly if desired to accommodate ahigher feeding device. I also preferably use baiile plates 26 and partitions 27 to concentrate the currents of air which are introduced by the several blowers 14,. It is customary to have the steam coils for heating purposes along one or both sides of the drier and I have shown the ordinary coils 28 and an extra coil 29 located at the end of the same. This extra coil need not always be used, but it increases the drying capacity of the device, especially as the blower adjacent thereto blows the heated air in directly against the material as it is fed into the machine and even while it is piled up on the apron 20 and also forces currents of air through it as it is passing up to the top of the machine by the action of the apron 9.1. The bafile plates 2-6 can be adjusted to control the air cinrrents if desired.
In front of the coils of pipes I have shown 1.sso,e4e
two screens 30 for keeping the material out of the heating coils and confine it to the spaceoccupied by the feeder. The direction of the air currents is indicated by the ar.
rows and it will be seen that they pass all around through iil'ltfiIIltltQl'ltl-l asfar asthey The material on the outside of the' pile dumped on the apron 20 is always eX- delivery end of the drying apparatus in some cases this part of the device can be shortened. E 1
In this way the material to be dried is'subjected to a preliminary dryingaction while it is being fed into the ordinary drier and large amounts of moisture can be extracted while the material is traveling to the apron 11 and removed before it reaches it." Thus the drying action is-rendered much more'efii cient than heretofore and also more rapid.
- I do not limit myself, except as expressed in the claims, to the details of a' unitary structure for a drierand'feeding device. I. p
Although-I have illustrated and described only a single form of the invention I am aware of the-fact that modifications can be made'therein by any person skilled i'n the art without departing fromthe scope of the invention as expressed in the claims. Therefore I do not wish to be limited to-all the details of construction herein shown and described,'but what I do claim is v 1-. -A dri'er forfibrous material having a casing, an endless apron therein for carrying the material, means for circulating heated air through the drier, and means located in'tlie drier casing in communication :AVit-h said air currents for separating the fibrous material from a quantity of material inbulk, spreading it out, and depositing it in a continuous manner on said apron, whereby the drying of thematerial will'be going onwhile it is'being separated, spread out and fedto the apro '2. The combination with a drier having means for conveying material to be'drie'd,
and means for heating theair in the drier, of a feed apron within said drier and in 'po-' sition to be subjctedt'o the influence of currents of heated air therein for prelimi;
