' To all wlwm it mm concern:

Be it known that I, LOUIS Johnson, a

citizen of the United States of America, re-

- move the moisture therefrom, said articles being delivered mechanically to said drying chamber and mechanic-all removed therefrom ina manner to permit the handling of the'wet and dried articles exteriorly of the cabinet.

A further object is to provide an apparatus of this character wherein a circulation of air will be maintained about the articles being dried at all times while they are within the cabinet, thus, through the elimination of moist air, preserving conditions whereby the clothes will be properly dried within the minimum time.

A still further object is to provide an apparatus of this character wherein the air delivered into and withdrawn from the cabinet will be so difi'used as to insure uniform conditions throughout the cabinet.

A still further object is to providean ape paratus of this character containing a normally closed cabinet within which a conveying mechanism is installed, the feed and delivery ends of said conveying mechanism being exposed exteriorly of the cabinet, automatically actin doors being provided whereby the artic es of clothing maybe introduced to the cabinet and removed therefrom without permitting the escape of any material volume of the heated air from within the cabinet;

A still further objectis to provide in an apphratus of this character a conveying mechanism which will subject the clothes being dried to the-action of the heat within the cabinet for the maximum length of time compared with the dimensions of the cabinet, thus permitting compactness in the structure without sacrificing the capacity of the apparatus.

A still further object is to provide in an apparatus of this character a conveyer mechanism wherein the weight of the clothes will not dis lace the conveyer in a manner to render it iable to such disarrangement as would render it inoperative.

A still further object is to provide in an apparatus of this character a conveyer mechanism whereby the dried articles will be automatically removed from the conveyer, thus making it necessary to have merely one operative for the apparatus.

A-still further object is to provide an apparatus of this character wherein the parts will be so constructed and arranged as to secure high eiiiciency as to output and uniform drying of the clothes placed therein. And a still further object is to provide an apparatus of this character which will not war under the moisture and heat, with a resu tant opening of seams and leakage.

The invention consists in the novel fea tures of construction and combination of parts hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings :Figure 1 is a front elevation of a machine embodying my invention; Fig. 2' is a plan view thereof; Fig. 3 is a verticalcross section on the line 3-3 of Fig. 2; Fig. 4 is a longitudinal section; Fig. 5 is a detail view showing a cross section of one corner thereof upon the line 5-5 of Fig. 1; Fig. 6 is a detail view of the conveyer mechanism; Fig. 7 is a detail View of the releasing device of the conveyer mec anism, showing a collar being delivered from the conveyer; and Fig. 8 is a modified form of gripper mechanism adapted for use in connection with my machine.

Like numerals refer to like parts throughp out the several views.

In the embodiment of my invention shown in the drawings, 1 indicates a drying cabinet adapted to have a circulation of heated air maintained thereby by means of the blower 2. This cabinet 1 is provided with double wallsto prevent the radiation of heat thereas a heating medium. In the bot-tom of thecabinet is a casing or tank 6 adapted to inclose the steam coils 3, said tank being adapted to receive the drippings from the clothes, the drippin' s being removable from the tank by any suitable means not shown. Extending over the top'of this tank is a foraminated drip board 7, having a plurality of openings therein adapted to admit water to the tank and to permit the escape of the air, after being heated by passing about the coils 3, to that portion of the cabinet adapted to accommodate the articles being dried. This board also serves as a distributor for the heated air. The gas burners 4:, 5, are arranged in pairs, as shown, upon opposite sides of the cabinet, and above each burner is a foraminated distributer plate 8. Preferably the cabinet 1- is made of sheet metal, and to cheapen the production thereof, give the desired stability thereto, and prevent the escape of the heated air therefrom, I unite the various sections composing same by means of a lap joint of peculiar'construction, which I will now describe. This construction is shown more particularly in F ig.

- 5 of the drawings, in which the inner wall of the cabinet is shown as being comprised of sheet metal sections 9 and the outer wall of sheet metal sections 10." The edges of adj oming sections 10 are turned outwardly, and the ends of these outwardly turned sections turn at right angles as at 12 to form an anchor adapted to be engaged by the lapped edges 9 of the adjoinin sections 9, which pass between a space le t between two sections 10 and are turned about and clamped upon the anchors 12 to form a tight joint and at the same time space the two walls 9 and 10 the desired distance apart to form an air chamber between same. The walls of these air chambers are also blocked apartas at 13, to prevent their collapse. To avoid any possibility of the loosening of the lap iron beam 17, about which is formed and crimped the edge of the front plate 18 ofthe front of the cabinet. The front of the cabinet is formed with door openingsat 19, the

portion of the front wall being reinforced upon one side of the door openings by the angle beam 20, about which the front sheet 18 is crimped, a recess 21 being formed between the

uprights

17 and 20 for the purpose of reinforcing the front of the cabinet and holding these uprights in position. Opposite the upright beam 20 is a vertical U- beam 22 which acts as one j amb for the door 23 and has the edge of the section 18 folded and crimped about same. The construct-ion upon the other side of the door 23 is a mere duplication of that heretofore described, and throughout the cabinet the various sections entering into the side walls are united in the manner described, thus forming a per-ma nent air-tight wall in amanner which will afford the desired air space between the walls to provide the requlred inert body of air for insulation purposes.

Leading from the outlet of the pump 2 is a pipe 24: having two branches 25 passing into thecabinet 1. These branches extend adjacent to the bottom of the cabinet 1, and

terminate in air distributers 26, 27, extend-- ing parallel with, and below, the steam coils 3 near op osite sides of the cabinet. The openings in the distributers arepresented upwardly, and the distributers themselves are of gradually reduced diameter to vary the capacity thereof so as to equalize the vol-- ume of air delivered at different points thereof. Adjacent to the top of the cabinet are two

similar air distributers

28 and 29, the out-let openings of which are presented downwardly, thus causing airto be projected in jets toward the center of the cabinet in a manner to cause it to circulate about the articles being dried, and to prevent the accumulation of moist air within the top of the cabinet. Extending from the delivery pipe 24 is a branch 30, of smaller diameter than said pipe 23, which pipe 30 discharges into a vent or draft pipe 31 forconveying the moist air from the cabinet for the purpose of maintaining the desired constant circulation of air within the cabinet. Communicating with the vent pipe 30 are the branches 32, from which depend the

rectangular pipes

33, 34, 35, supporting the foraminated duct 36 extending about three sides of the cabinet adjacent to and above the heating means. By this construction, it will be observed, the air within the cabinet is exhausted by a natural draft through the pipe 31, which exhaustion is accelerated by the siphon or in jector action from the branch 30 leading from the pump, the outlet of this pipe 30 being connected with the off take pipe 31 directly above the point of junction of the branches 32- and 33 with said last named pipe. The pump or blower 2 therefore has the twofoldfunction of delivering air to the cabinet while at the same time aiding in the exhaustion of air therefrom to assist in maintaining the desired circulation of air cabinet 1, is a conveyer 37 carrying a plurality of hangers 38 adapted to receive the articles to be dried. This conveyer is adapted to have continuous movement,- and one end thereof is exposed exteriorly of said cabinet 1 so as to permit the operator to attach the articles to be dried thereto and to permit said articles after being dried to the desired extent, to be delivered therefrom exteriorly of said cabinet. This conveyer 37 preferably consists of a sprocket chain which will not be subject to excessive contraction and expansion by the heat within the cab- E plurality of hangers 38 each of which is inet. The use of a sprocket chain also permits the conveyer to'be readily driven and guided. To increase the interval of time during which the articles are subjected to the action of the heated air circulated withof hanger shown in Figs. 6 and 7 being i especially ada ted for use in connection with in the cabinet 1, Iprovide guiding means for said conveyer which will cause each hanger 38 to travel back and forth in the cabinet a numberof times before passing to the delivery point. These guiding means comprise the three sprocket wheels indicated at 39, 40 and 41, which are triangularly arranged in a manner to cause the conveyer to travel over four parallel courses while within the cabinet.

Mounted exteriorly of the front of the cabinet and preferably in alinement with the

sprockets

40 and 41, are the sprockets 42and 43, about which the chain conveyer 37 passes, these

sprockets

42 and 43 being space'daway from the front of the cabinet sulficiently to afford the operator sufficient time to adjust the articles to be dried hpon thehangers 38, and at the same timepermit 'spacefor the positioning of a receptacle to receive the articles delivered from the cabinet by means of the conveyer.

"To prevent the sagging of the conveyer between the

sprockets

41 and 42, 41 and 39, 39 and 40-, and 40 and 43, I provide the T-

beams

45, 46, 47 and 48, two of which, as 46 and 48 project forwardly of the cabinet to a oint adjacent to the

sprockets

42 and 43. %xtending across the front ofthe cabinet between the

sprockets

42 and 43 is a T-beam 49 adapted to guide the conveyer between said last named sprockets. The

beams

45, 46, 47 48 and 49 form tracks adapted to receive the rollers\.5( on' a bracket" 51 carried.- by the chain 37 thus preventing the sagging of this chain and insuring its constant mesh with the various sprocket wheels. These various tracks do not extend aboutthat' portion of the peripheryv of the. sprocket wheels engaged by the chain, sup ort not being required at such points. 'he raised edges of these tracks will serve to confine, or prevent the derailment of, the rollers 50.

The front of the cabinet is provided with two pairs of self closing doors, 52 and 53, one pair of which as 52 opens inwardly, andthe other pair of which as 53 opens out wardly. The tracks 48 and 45- project through suitable openings between the doors of the

pairs

52 and 53 respectively, these doors also being provided with openings for the chain 37.

The

sprockets

40 and 41 are mounted in bearings carried by the slides 54, which slides are-acted upon by a weight 55- in a manner to automatically take up an slack :in the conveyer which might result in said conveyer riding upon the sprocket teeth and becoming disengaged therefrom. v

The chain 37 has pendant therefrom a adapted to support an article to be passed through the drying cabinet. ,The construction of these hangers 38 may vary to adapt them for use with different articles, the form collars and on s, and the modification shown in Fig. 8 especially adapted for use with other articles which must be gripped by the hanger.

To increase the capacity of the machine, the holding means. of the hanger are duplicated so as to increase the capacity of each hanger. The construction of both forms of hangers shown inthe drawings is identical with the exception of the detailed construction of the holding means thereof; The hangers 38 each comprise a cross head 56 having bifurcated ends. This cross head is supported by the suspension rod 57"from a link of the chain 37, directly below the-yoke 51. The cross head 56 extends for a con siderable distance. and to an equal degreeupon each side of the chain 37, the forked ends thereof being adapted to engage with and open either pair of

doors

52 or 53. Each arm of the forked ends is provided with an anti-friction roller as 58 to minimize the friction between the cross heads and the doors. a

Depending from the longitudinal center of the cross. head 56 is a bracket 59, adapted to carry the means for engaging the article to be dried-, the lower end of this bracket being oflsct as shown for the purpose of permitting the use of anover-balanced cooperating member 60 pivoted thereto'at 61'. With the form of supporting means shown in Figs. 6- and 7, the bracket 59' carries a post 62 adapted to penetrate the button hole of a collar or cuff, the cooperating member 60 having a bifurcated end straddling said post so as to eject or deliver the articles strung upon said post 62 in a manner to be adjacent tothe bifurcated end thereof isan arm 63 by means of which the said member may be automatically actuated to remove the articles therefrom. This mechanism is duplicated on opposite sidesof the chain 37 Mounted exterlorly of the cabinet 1, upon the rail 45, and adjacent to the doors 53, is an elongated cam plate 64 adapted to engage the arm 63 and oscillate the member 60 upon its pivots in a manner to cause the bifurcated end thereof to engage the articles upon the post 62 and deliver them therefrom. There are two cam plates 64 adapted to simultaneously engage both arms 63, so that all articles held by each hanger are simul taneously delivered after leaving the cabinet.

In the modification shown in Fig. 8, the details of construction of the hanger are substantially the same as heretofore described, excepting that instead of using the post 62, the bracket 59 and the holding member 60 are provided with oppositely disposed holding studs 65 adapted to grip an article between them, the actuation of the member 60 in this form of the invention having the same result as heretofore described, and being accomplished in the same manner.

The pivots61'of the member 60 being offset as shown, the weight of this member will, in the form of the invention shown in Figs. 6 and 7, make the gripping mechanism operative by exposing the end of the .post

62, while in the form of the invention shown in Fig. 8 of the drawings, this weight will have the effect of holding these articles in the desired position.

The chain 37 is driven from the sprocket 39 by means of the beveledgea-r 66' driven from the beveled gear 67 upon the shaft 68.. This shaft is driven from the countersha'ft- 69 through pulleys 7()7 1, and belt 72, the, also driven from the shaft 67 by pulleys 7 3-74 and belt 75. The shaft blower '2 bemg 68 is geared down, while the blower is geared up. The shaft 69 is driven from the motor 76 by means of the belt 77 and pulleys 78. By this construction the speed of traverse of the chain 37 and the volume of air circulated within the cabinet 1 may be simultaneously controlled.

The operation of the herein described apparatus is substantially as follows: The blower 2 is first sct'in operation so as to deliver air through the pipes 25 and

distributers

26, 27, 28 and 29 to the cabinet 1, at the same time drawing the air through the duct 36 and

pipes

33, 34, 35, and therefrom to the vent pipe 31, the by-pass pipe 30 leading from the delivery pipe of the blower setting up suflicient' circulation of air within the pipe 31 to insure the withdrawal of air through the pipes 33, '34 and 35. The air passing from the .lower distributing pipes 26,27, passes upwardly about the heatmg coils 3 or tubes 4: and 5, and is distributed by the foraminated plates 7 and 8 to all parts of the cabinet 1. At the same time air from the distributing

nozzles

28, 29, will be forced downwardly within the cabinet, preventing the accumulation of moist air in the top of the cabinet, and at the same time blowing directly upon the articles carried by the hangers 38 upon the conveyer 37.

to adapt the same machine to either steam heating or gas heating, and if desired both of these forms may be used in one and the same machine.

By the construction of cabinet described, I am enabled to make the entire cabinet of metal, air tight throughout, and having an air insulating space or chamber about all portions thereof excepting the front which is intermittently opened and closed. The central door 23 is merely for the purpose of permitting access to the interior of the cabinet.

While the apparatus is in operation, it is merely necessary for one operative to place the articles upon the hangers 38. The machine being in operation, it is merely necessary for this operative, when it is desired to use the machine for drying collars and cuffs, to slip the button hole of the collar or culf over the post' 62, while the chain 37 is in motion, this chain immedi .ately carrying the articles into the cabinet 1. The brackets 59 being arranged on the longitudinal center of the cross heads 56, these cross heads when they reach the doors 52 bring the rollers 58 into engagement with said doors and automatically open same inwardly to admit a hanger 38 with the articles thereon to the cabinet. The bifurcated ends of the cross. head 56 prevent the closing of these doors until after the articles have passed same, but immediately upon the passage of the cross head 56, these doors automatically close until opened by the next hanger 38. The conveyer chain 37 carries the hangers and the articles supported thereby back and forth within the cabinet four times, finally bringing the cross head 56 into engagement with the doors 53 which are automatically opened outwardly in the same manner as the doors 52 to permit the articles to pass from the cabinet 1, these doors also closing automatically after each hanger 38 has passed therethrough. After the hangers 38 pass through the doors 53, the arms 63 thereof upon opposite sides of. the cross head 56 simultaneously engage the cam plates 64 which oscillate the member 60 to cause the bifurcated ends thereof to move along the posts 62 and move any collar or' H cufi' thereon along said stud until itis finally delivered therefrom to .a suitable receptacle, Immediately upon passing the plate 64, the Weight of the member 60 will cause it to automatically assume its normal position where the post 62 is exposed for the reception of further articles to be dried. The conveyer 37 extending through a portion of the cabinet 1 substantially midway between the heating means and the top of the cabinet, and spaced wall away from the sides thereof, brings .the articles into a zone where the heated air will .circulate freely about same, so that each article carried by the hangers 38 will be subjected to the action of this air in circulation by reason of the tortuous course it follows while within the cabinet, and will be thoroughly dried be fore betng delivered in the manner referred to. The

tracks

45, 46, 47, 48 and 49 will prevent the saggin of the ..chain 37 and at the same time wil eliminate any tendency of the chain to twist, in factsustaining practically the entire load of-the conveyer and preserving the desired relative, position of the operative parts thereof. 1 If it be desired to increase the time during which the articles undergo the drying operation, itis merely necessary to reduce the speed of the motor, which will reduce the speed of traverse of the conveyer mechanism, at the same time reducin the velocities of the air currents within t e cabinet in a manner to raise the temperature of the air within the cabinet slightly.

In the modification shown in Fig. 8, the mode of operation is substantially identical with that heretofore described, except that with the action of the member by the cam "pl ate 64, the grippers will be separated in a manner to drop the article held between same.

It is apparent that-one operative only s required to run this machine, as the only work the operator must do isto place the articles upon the hangers 38. p

A machine constructed in accordance with my invention has great capacity because of the capability of multiplying the mnnber of hangers upon the .one conveyer, and the continuity of operation of the device in drying articles carried by successive hangers. The take-up weight 55 and, slides 54 will ermit any slight sagging which may occur 1n the conveyer chain 37 under varying loads, and will automatically take up this slack when necessity demands.

It is not my intention to limit the invention to the precise details of construction out departing from the spirit and scope of the invention.
