UNITED STATES LOUIS \TUDELSON, OF NEW YORK, N. Y.

DRIER.

Application filed May 28, 1924, Serial My invention relates generally to laundry machinery and has reference more particularly to d riers \vhereinarticles of clothing or other materials to be dried are hung upon carriages which are movable into a drying chamber where the moisture in the clothing is evaporated therefrom.

My invention has for its principal object to provide a drier of the character hereinafter described, which contains certain novel and efiicieut .featuresof construction for supporting. arranging and removing the articles to be dried in the drying cabinet.

A further object of the invention is to provide a drying cabinet constructed of separable panels having interlocking joints and separable fastening means for holding the top, bottom and side walls together without the use of rivets, bolts or other permanent connecting means,

lll'icrs in general are constructed with the usual drying cabinet having a series of overhead racks from which are suspended a plu ralit v ot drying frames. The drying frames are ordinarily slidably mounted on the racks which either extend substantially beyond the front of the cabinet in a permanent arrangement or are composed of telescopically disposed members which may be projected outwardly from the front of the cabinet when the driers are to heloadcd or unloaded as the case lua \'-be. .-\cc(. rding to the former design the permanent overhead racks require considerable floor space, in fact the additional space employed is substantially the same as that for the cabinet itself. since in order to (XpOsc the driers they must be projected to their full length in front of the cabinet. This feature is particularly undesirable where driers are to be installed in small apartments or in places where every. square foot of space must b utilized to the best advantage. The collapsible rack tvpe of drier has overcome this undesirable feature to a certain degree, but. while the outside projecting rack is not Pl'ljltlll when the machine is closed. space hunt be provided for the drying frames in front of and in line with the cabinet when extended with the racks. This space factor would not be of great importance were itnot for the fact that this type of drier makes necessar the use of a construction which comprises a forward support for the collapsible rack. the support usually taking the form of an upright member attached to the ends of upper and lower racks and having suitable No. 716,340 Renewed June 30, 1927.

castors or other rolling means adapted to contactwith the floor. The requirement for a more or less rigid construction has made it practically impossible to avoid using this outer supporting or bracing element and with such a means of support a substantially level floor must be provided in front: of the drier cabinet in'order that the projecting portions of the racks may be readily withdrawn from the fixed portions within the cabinet. Therefore, it drier racks are not a permanent arrangement in front of the cabinet an especially prepared level space must be provided to a certain extent.

According to the present invention the usual disadvantages pointed out above have been overcome with efficient and practical means for holding the materials in the drying cabinet and for readily removing the materials therefrom without the use of an outer supportfor the drying frame.

Theinventionisillustrativelyexemplifiedin the accompanying drawings, in which, Figure 1 is a perspective view ofmy improved drier showing one half of the cabinet open and a drying frame projected outwardly fromthe front of the device; Figure 2 is a similar perspective view of the cabinet showing the entire device in closed position; Figure 3 is a perspective view of the inside of the drier as it would appear if one side were removed and the near drying frame or carriage were not in the cabinet; Figure 4 is a perspective .view of one of the carriages and a section of the guide channels therefor: Figure 5 is a sectional view of the type of bracket used in the construction of the carriages for receiving and supporting the clothes sticks: Figure 6 is a front elevational view of the same bracket; Figure 7 is a sectional view of an upper corner of my improved drier cabinet showing in perspective the relative arrangement of the different layers of material which make up the top and side panels of the cabinet, and the separable fastening means used to attach the sides and back of the cabinet together: Figure 8 is a perspective view of a corner and mid-section side panel taken in section below the top section of the cabinet; Figure 9 is a perspective view of an angle iron having a portion removed to provide engaging members for holding the panels of the cabinet together.

Referring now to the drawings, and particularly to the embodiment thereof shown will be apparent that even when theeral. A; partition in;Figures 1 to 6, 10 denotes the drier cabinet having to and bottom sections-11 and 12,

10 is divided into two chambers or compartments, .the lower of which is accessible through the lower opening 18 and contains the heating unit 20, whichmay be of any of thewell known types used with driers in gen 21 separates the lower chamberirom the upper or drying chamber 22 which in turn is accessible through the opening 16 closed by the doors 17.

' The partition 21 comprises a lateral division having transversely arranged angle bars 23 attached to the front and back panels, 15 and 13, at a plane disposed just between the er and

lower openings

16 and 18, and two pairs of longitudinally supported guideways or channel bars 24 attached at opposite ends to the angle bars 23. The guideways 24 of each pair are arranged so-that their open sides face each other and the under side or wall of each is provided with projecting lips 25 upon which a screen frame 26 is supported between the guideways of each pair. The spaces at opposite sides of the cabinet between the upright side walls 14 and outermost guideways 24 of each pair are closed filler members27 which comprise inverted c annel pieces supported at opposite ends upon the angle bars 23 and provided with a series of openings 28 through which the air heated in the lower chamber is admitted to the drying chamber 22.

The guideways 24 as previously stated are arranged in pairs and the outside transverse dimension of a pair is substantially smaller than the space occupied by one door 17 in the opening 16, so that it is only necessary to open one door at a time when the device is being loaded with clothes. The guideways 24 adjacent the opening 16 are bevelled toward the ends to accommodate the bevelled ends of hinged guideways 29 which are pivoted to the fixed guideways 24 and which may be swung to an upright position, as shown in Figure 3, when the doors 17 are closed. The outer ends of the pivoted guideways 29 of each pair are connected by a handle bar 30 which also acts as a stop to \prevent the drying frames from becoming detached from their guideways, when the latter are dropped to form a continuation of the fixed guideways 24. It has been found desirable during the operation of the invention to be able to close the doors while a drying frame is being loaded or unloaded, so as to avoid the loss of heat in the cabinet, and for this purpose a lower section 31 is provided for each door 17, the section 31 being a separate member having a hinge connection doors 17 and an 32 with the main panel of the'door propeijthe hinge being'arrang'ed'so asto permit the sec which comprises 11' base frame'35 "having' rollers 36 arranged at eachj'corne'r' and'capable of running between the upper and lowerwalls ot the guideways, Parallel uprights 37 are supported at their lower ends in the base frame 35 by means of central angle pieces 38 and brace rods 39, as illustrated particularly in Figure 4. The upper elevation of the parallel uprights 37 are provided with'lateral connecting pieces to receive and support brackets 41. The brackets 41 are arranged in rows so that the lowermost bracket is in the center of the space between the uprights, and the next row'above comprises two brackets disposed at opposite sides of the pieces 40. For the urpose of illustration two rows of single an two rows of double brackets 41 are shown,

be understood that any required number of rows may be utilized depending o -'course upon the height of the cabinet-proper. brackets 41 are clearly illustrated in Figures 5 and 6 and comprise a back plate 42 having corner openings 43 to receive rivets 44 which project through the cross pieces 40. An integral socket 45 projects outwardly from the face of theback plate 42, the socket being sub stantially triangular in transverse section and at a point about midway of its length the top lateral wall is cut away. The nder surface of the short length of the top will is provided with a transversely disposed integral rib 46 projecting the full width of the socket 45, the rib being provided to engage a notch 47 cut in the upper surface of a drier rod 48. The drier rods 48 are triangular in cross section and composed of tubing, bent sheet metal or any other suitable material used in the construction of hollow rods. The inner end of each rod 48 is provided .with a filler 49.7which acts as a reenforcing member and enables the rod after being inserted into the socket 45 to support considerable weight without fear of becoming bent or otherwise distorted. The rods are adapted to fit snugly within the sockets and are prevented from being withdrawn by a direct outward pull by means of the ribs 46, and from sagging by means of the under support which the free ends of the sockets afford the rods beyond the top wall. Any downward pressure upon the rod will cause the end adjacent the back plate 42 to closely engage the under surface of the top wall since the outer. free end of the socket virtually but it will The V 40 which are spaced apart point about which the rod may bear. Each rod, on the other hand, is readily removed by simply raising the outer end until the inner end has swung downwardly, in a space provided by a curved under portion 50 of the socket, shown in Figure 5, and until the notch 47 is free of the rib 46, thereafter the operation being completed by withdrawing the rod at an angle to the lateral axis of the socket.

A particular feature of this construction resides in the fact that the drier rods 48 are not supported at their outer ends and may be removed from the apparatus for cleaning or other purposes without disturbing any other part or'parts of the machine. It is further found that clothes or other articles and mate rials about to be hung upon the rods'may be placed in position much more readily over their freeends than is possible when the ends are closed by a front support or panel. In

forms a fulcrum order to facilitate the manipulation of the drier ames or carriages the lowermost rod 48 of each drier is'provided-with a handle member 51 attached to the outerend so that by merely drawing outwardly on the handle the whole carriage 34 will follow the

guideways

24 and 29 to the outside ofthe cabinet, as illustrated in Figure 1. Y

' The circulation of heated air in the cabinet is controlled by .a flue 52 which is attached to the rear wall 13 and extends from a point just above the partition 21 to and'through the top panel or section 11. The lower end of the flue 52 opens into a transversely disposed flue 53 which comprises a channel memr having its edges turned outwardly and attached to the back wall 13 and further having its closed front portion and lower wall provided with a series of perforations 54 for the reception of the moist heated air which has first passed upwardly through the dry-.

ing chamber 22 and then downwardly again as it hecomes'cool and saturated with the moisture removed from the wet clothes, etc.

he general'construction of my improved cabinet provides separable front, backand side panels which are held together by means of topand bottom panels having continuous marginal grooves disposed in their opposite inside surfaces. said grooves being adapted to receive the ends of the front, back and side panels. In order to insure further fastening facilities the adjoining panels are provided with straps having grooves for the reception of locking members, as hereinafter described in detail.

My particular cabinet construction, illustrated in Figures 7, 8 and 9, is the result of an effort to avoid as far as possible, the use of rivets or other permanent fastening means, in the final assembly of the walls. Each wall whether top, bottom, specially arranged interlocking features which enable a cabinet to be readily knocked channel or groove 59.

or side is provided with down for packing and transporting and then again set up at the'destination without the aid of skilled workmen.

The top section ll and bottom section 12 are identical and a detailed description of but one section will suflice for both. The top section, shown in Figure 7, comprises a hollow member and an inner metal sheet 55, the latter being spaced substantially apart from and below the outer sheet 54, w iich at its 'four sides is bent downwardly at right angles to form a depending flange 56. The under sheet 55 isdisposed parallel to the outersheet 54 to a marginal line short of the flange 56, where it is bent upright at right angles to engage the under surface of the upper sheet 54. This upright inner wall arrangement forms an 57. The-metal then rojec-ts tothe angle of the flange 56 and is disposed against theupper sheet 54 to provide a top wall 58 of a The extreme marginal portion of the metal sheet is then bent wardly at right angles to the plane of the top wall 58 to arrange a flange or outer wall 60 which rojects to a point short of the lower edge 0' the flange 56, so as to enable the extreme marginal bent back upon pending edge of tial distances apart throughout the top section, Z-shaped reenforcingbars 61 are disper and lower metal le rivets or spot Welds posed between the

u sheets

54 and 55, suita being employed to fix the position of the members. a

'The sectional view shown in'Fi re 7 furtherillustrates a portion of the lint panel 15, which comprises a'hollow marginal frame adapted along its upper edge to seat in the channel 59 at the front of the top section 11. A similar disposition of the lower portion of the frame is made in the same channel in the front of the bottom section 12. The frame itself comprises a front channel shaped sheet metal portion 62 having the closed side 63 arranged against the inner face ofthe combined flanges 56 and 60 and projecting downwardly to define the wall of the opening 16. The.

while the lower flange 65 and its embracing portion of the back section 66 forms a stop or jam for the doors 17.

The doors are hollow rectangular sheet metal members having a front section 67 provided with edges bent at right angles to composed of an outer metal sheet 54 I downas v portion of the latter to be. itselfand over the raw do the flange 60. L'At substanthe plane of the door and then parallel to the face of the latter to provide a projecting flange 68 which embraces the inner face 69 of an inside section or inner wall 70 of the doo the marginal portion of this wall 70 bei g bent at right angles to project parallel to and against the lateral edge of the outer section 67. The air spaces between the walls of the hollow sections of the present construction are provided to insulate the heating or drying chamber 22 from the air surrounding the cabinet.

An interlocking corner of the front or back panels with the adjacent side end panel 14, is illustrated in Figure 8, wherein the outer vertical edge of a front or

back section

15 and 13, comprises the sheet metal front wall 63, bent at right angles to its normal plane to provide a narrow flange 71. The flange 71 includes a projecting portion which is bent back upon itself to embrace the out side flange 7 2 of the inner wall 66, the latter wall being bent inwardly at right angles at a point short of the outside flange 72 to provide a channel 73 adapted to receive and have its walls closely embrace the projecting flange 74 of a side panel 14.

The side walls or panels 14 are preferably constructed in sections and for illustration three such sections are shown; two end sections 75 which are identical in construction; and a central or intermediate section 76 which is provided with similar interlocking vertical opposite edges. For the sake of brevity, but one of the end sections 75, and one edge of the intermediate section 76, will be described in detai The end sections 75 are made of hollow sheet metal construction of width substantially the same as that of the front and b: ck panels, and comprise an outer sheet 77 bent back upon itself along its upright outer edge to form the flange 7% which is closely embraced by the walls of the channel 73. The bent over portion of this flange 74 embraces in its turn a flange 78 of the rear or inner wall 79 of the hollow section 75. The flange 78 is formed by a projecting portion of the wall 79 which is bent towards the frontwall 77 at right angles to its plane, the bent portion being adapted to seat against the inside face of the inner wall (36, as shown in Figure 8. The opposite upright edge of the end panel 75 is formed by the marginal edges of the front and back walls 77 and 75), the said edges being bent towards cach other and at right angles to the plane of the wall propel and then being bent back upon themselves to provide spaces into which the end portions of each wall may be inter-engaged by sliding one member over the other when the end panel is being assembled. The arrangement just described provides a perfectly square uprightedge 79', as will be clear from the illustration in Figure 8.

The upright edge of the intermediate panel or section 7 6 is virtually a channel or groove the walls of which are adapted to closely embrace the square edge 7 9' of the end see tion 75. The rear sheetmetal wall 80 of intermediate panel is bent back upon itself along its upright. edge to form a flange 81 and the projecting portion thereof is bent at right angles to the plane of thewall to en,- gage the inner'face of the front wall 82 where it is bent to lie parallel thereto. The outer wall 8:! projects to the end of the bent portion of the'rear wall and is then bent back upon itself to embrace the last named bent end of the rear wall. the end portion at this point forming a second flange 83 parallel to the first flange 81. Together the flanges '81 and 83 provide the channel or groove to receive the end of the end section as previously stated. Thus it will be clear that my improved cabinet is composed of panels which interlock at their edges by means of a tongue and groove arrangement to form a substantially tight container without the aid of the usual rivets, etc.

In order to hold the several sectionsor panels together after being assembled 1 provide at predetermined intervals about the lateral corners of the top, sides, front and rear panels and at the upright corners of the sides, front and rear panels, a locking member, which comprises a length of angle iron 8t having an angular portion cut away from both planes of the bar to form separated projecting arms 85 disposed on planes atright angles to each other, as shown in Figure 9. hese arms 85 are adapted to be inserted in parallel openings or guides 86 formed by a U-shaped strap, one of each of the latter being secured to adjacent walls near the corner where the two walls meet. This particular arrangement and locking means and the manner in which the same is used is clearly illustrated in both Figures 7 and 8.

Referring to the operation of my drier it is merely necessary to refer to Figures 1, 2 and L) which show the dropped position of the guideway hinged projections 29 and the ca rriage 2H partly projecting from the cabinet, and also the position of the carriage when the latter is disposed within the cabinet.

It will be clear that due to the two sets of wheels or rollers on the carriage being widely separated from each other and being further arranged in the guideways below the overhead flange of the latter, there is practically no chance of the carriage tipping,forvvard under the weight of the loaded drier rods 48. This construction is of the greatest importance since it enables the ends of the rods 48 to be free and unhampered by a supporting element or other front panel member.
