LAUNDRY-nains.
To all whom it may concern:
Be it known that I, ARTHUR KENDRICK, a citizen of the United States, and resident of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new` and useful Improvements in Laundry-Driers, of which the followingis.
a specification.
This invention relates to laundry driers of the type in which the clothes to be dried are placed in a rotary reticulated or perforated drum inclosed in an air casing' through which a current of hot air is circulatedby suitable fans or blowers for the purpose of absorbing the moisture from the articles to be dried.
Machines of this type comprise an louter `casing for containing the rotary drum, the
heating pipes and the air circulating means and are partly subdivided by suitably arranged partitions into a drum compartment and-a blower compartment in which are located the fan blowers which direct the cur-V Y 'rents of air over the heating coils through a suitably located opening into the drum compartment so that hot air circulates through the rotary' drumI and may be returned through a suitable opening in the partition back to the blower compartment havi the screen to clear.,the same.
provision usually being made to catch the lintcarried by the air from the drum on a the drum compartment may be returned in whole or in part to the lower compartment' for re-use, or maybe partly-or entirely .di-A
verted therefrom. Another feature ofthe invention consists in providing a construction and arrangement of screen that makes it possible to clear the screen of lint practi- Specication of Lettersilatent. ApplicationV mea may 19,

cally instantaneously after each run of arti- I cles to be dried v and Without the necessity of opening the casing or stopping the machine.- These and other features of the invention will be `particularly pointed out in the following specification and will be. dened in the claims hereto annexed.
In theY accompanying drawings I have Figure'l is an end elevation showing the location of the heating coils, the various air circulating partitions and the inclosing caslng.
F ig. 2 is a sectional elevation showing the linterior construction and arrangement of the air circulating passagesand-fan as well as the] adjustable shutter and dumping screen.
F ig. 3 is a detail view in front elevation showing the I neans for locking the shutter in its different positions of adjustment.
The inclosing casing a in which is mounted the drum shaft bcarrying the reticulated or perforated drum b is of suitable shape to properly inclose the rotary drum, the-l air circulating fans and the heating coils. At its front upper ortion it is provided with a door a2 for a ording access to the drum for the purpose -of putting in and taking out the articles to be dried. From a point below the bottom .of the drum b and quite close thereto is placed a curved baifle plate or artition' a3 which fol` v lows the curvature o the drum to a point near the top of the rearside of the drum as shownfin Fig. 1. To the frontedge of this baille plate-which extends the length of the casing Yis placed ari inclinedI partition a whose lower end is attached to a longitudinal forming a portion-of the front wall in this instance.fj,s placed a longitudinal ledge a" angle plate a.' On thefinside of a door a50 which forms an abutment for the front edge .of the screen c the rear edge of said screen 'abuttingagainst the angle bar a when the screen is in the normal operative position fas indicated in dotted lines -in Fig. l. l
"This screenis preferably curved and at' ortion is secured to a rock extends through the opposite end of the casing and is ,mounted-in suitable bearings formed by horizontal reinforcing its 'middle plates 02- which have two properly positioned perforated lugs c3 to receive the spring bolt c4 in the operating leverI c5 by which the screen is reversed for dumping purposes. The screen is shown provided at its normally front edge with a reinforcing f angle bar c? which in the reverse position and keep it in alinement. `Near the bottom ofrthe serves to close the gap between the angle bar c6 and they edge of the screen and vwhich also serves to stifen the frame work of the screen front wall ofthe casing a there is formed ,by means of the longitudinal plates as a3 forming partitions or false bottoms, an offtake passage leading to the oiftake flue tu which discharges into yan offtake pipe all at the back ofthe machine.
A screen d and an additional screen am serve to prevent the passage of lint into the offtakepipe. In the space between the baiile plate or partition a3 a5 a and the wall if-N015 in front of the heating chamber are `placedl one or more fan blowers e through whose discharge outlets -e the air escapes throul h vthe partition a15 into the heatin g ll' compartment containing the steam coils f,
` the intake of these fans being as usual-on the side of the fan casing.
Near the bottom ofthe casing just above the partitionl a? is mounted a longitudinal rock shaft g extending through the'opposite ends of the casing for a bearing support tol which is secured a platel orshutter g of sufcentlength to overlap the lower edge of the partition plate a5. The width ofthe ,shutter and the curvature of the screen c are so .correlated that when the screen .is in operatlve .position indicated in Fig. 1, the
shutter is capable of swinging from one edge of the screen'to the other against the adiat cent angle plates a6 c? while the edge of the shutter is close to thescreen so as to prevent any substantial passage of ,air between the under side of the screen land the upper edge of the shutter.
.To the outside of the end offtlie casing is secured the bracket ghaving an are shaped 'perforated member g4 having perforations so that the hot dry air passes to the upper part of the casin down around the upper edge of said ba e 'plate and through the 'perforated drum and returns through the' screen 0"t`o the longitudinal compartment below the screen the front lower portion of the casing. Y
If the shutter g be in the closed position Vindicated in Fig. 2, it is obvious that none of the air that has passed the drying drum will return to the fan blowers but will pass through the'screend beneath the false bottom a9 to the outlet flue a and the exhaust pipe all. If, however, the shutter Agbe adjusted to its extreme forward position all of the air that has circulated through the drum will be returned to the fan blowers land again circulated through the heating chamber back to the upper part of the drum. In Fig. 1 the shutter g is shown in one of its interior positions of adjustment in which la portion of the air returns to thel blower while the other portion passes along to the dischargepipe. On -one end of the casing covering the compartment v'containing the fan blowers there is provided a screened opening .It which may be wholly or partly ,closed by a sliding door It so as to admit or exclude to any desired extent fresh air from outside.
j After each drying runthe operator dumps the lint catching screen o by pulling out'the locking pin c* forming the handle of the lever c5 and swings it over until the locking pin is engaged with the forward perforated lug e3 by which movement the'screen willV assume the position as shown in Fig.v 2' with its upper siderunderneath and with -its front edge pressed. against the underside of the angle bar a". This is an operation which can be lperformed practically instantaneously and the jar or shock caused by' the edge of the screen striking against the'angle bar a6 causes the collected lint to drop to the bottom of the compartment, the shutter g having previously been shifted to closed position as s own in Fig. .2. 'Any loose particles of.
lint adhering to the vscreen when in reversed position will be instantly cleared olf .by `the current of air passing through. It will `be noticed that with this arrangement the screen may be cleared after each run of clothes without lossof time and without having toopen the casing -to get access to the" screen `or to remove it forcleaning pur.-
poses. At the end of the day or of the weekf the bottom of the trough 'or compartment.
lying below the screen and in .front of the shutter g may be cleaned 'when the machine is not in useby removing the lint therefrom as a.' The screensl al and am serve to ref vent the lint in this compartment fro escapingy into the room through the -outlet pipea11.' v On one end of the heating compartment is placed `a removable slide door a?. :The heatingpipes are arrangedin :separate series of verticaly coils f as indicated in Fig. 2 and the upper end'of eachsuch vertical coils is through anysuitable opening or door such i i connected to an inlet manifold f and atA their lower ends to an outlet manifold f2. In case of leakage of any steam coil the ldoor at may be slid open at the rear to expose the coils for examination and the particular coil at fault may be uncoupled from its two manifolds and withdrawn from the casing without disturbing the'other coils. This is a very useful and convenient feature of the present invention.
I believe that ,I am, the first t-o employ a dumping and self-clearinglint-catching screen that can be operated from the outside of the machine the advantages of which have been explained.
