13 Claims.

' clothes washing operation in the home, in that it eliminates the necessity and annoyance of stringing clothes-line and using clothes pins for securing the various articles thereto, and the problem of properly supporting the line to prevent soiling of the clothes. Such devices, also permit expeditious drying of the washed articles in a period of time materially less than that required when suspended in a normal manner on i a clothes line, either indoors or out-doors. Also,

such devices always assure proper drying of the clothes immediately after washing, irrespective of weather conditions. When clothes or other washed articles are hung on a line out-of-doors, in addition to the substantial labor involved, there is always great danger that the drying thereof will not be promptly eflected; in other words, weather conditions are always a controlling factor. Driers of this class definitely remove the hazards of proper clothes drying and is nowise subject to or dependent upon weather conditions.

One of the objects of the present invention is to produce a novel and improved clothes drier of the character indicated, which is of simple and ru ged construction, highly eflicient and capable of economical manufacture.

' Another object of this invention resides inthe provision, in a drier of the character described, of elements so that the natural convection currents of the burnercause an influx of a continuous supply of fresh air for admixture with said natural convection currents and causes said admixture to circulate around and over the articles to be dehydrated; said arrangement of elements being such as to preclude any appreciable amount of recirculation of the admixedair within the drier.

-A further object is to provide an improved drier of the character indicated comprising a frame structure formed to provide a relatively large opening at its upper end to constitute a draft outlet and a sheet of flexible material surrounding the frame and constituting the vertical walls thereof for enclosing the wet or moist articles suspended on the frame structure; said flexible sheet material terminatinga short distance above the floor to provide a draft inlet from all directions for assuring substantial circulation of the heated air currentsaround the wet or moist articles suspended in the frame for effecting expeditious drying or dehydration thereof.

Still another object of the invention resides in the provision of an improved construction, which may be quicklyv and easily assembled, or erected, or dismantled for convenience in shipping or storage.

Other objects and advantages will appear in the 15 following description taken in connection with the accompanying drawings, in which:

For purpose of illustration, I have herein shown the present invention as embodying heating appartus in the formof a gas burner. It will be apparent, however, that other suitable forms of heating apparatus may be employed with equal facility, and with substantially equivalent efficiency and other similar advantages.

The device shown in the drawings include a frame'structure, comprising two spaced-apart up rights or standards I0, preferably in the form of tubular members or pipes, the lower ends of each of which are rigidly secured in five-way" pipe fittings H, by set screws ll. Rigidly secured by tapered pins il in a pair of opposed openings in each fltting, are a pair of oppositely extending substantially horizontal members 12, the outer ends of which are down-turned to engage the floor, and constitute feet for the frame structure. The standards It are rigidly connected together at their lower ends by a horizontally extending tubular member or pipe I, which, as hereinafter described, also constitutes the gas burner. The opposite end portions of the pipe I, extend through a pair of aligned openings in the fittings II, and secured thereto by set screws ll. The upper ends of the standards are rigidly connected together by a horizontally disposed closed loop frame I 5, which, as shown, is of substantially rectangular form and is composed of two oppositely disposed generally U-shaped rods It, the ends of which are formed with.downturned terminal portions II, as seen in Fig. 5 adapted to be seated in sockets l8, formed in the upper ends of the standards l0. The sockets are formed by depressing diametrically opposite portions of the upper ends of said standards, as seen in Figs. 4 and 5. This construction thus permits quick and easy mounting or detachment of the loop frame members 18 with respect to the standards. The

loop frame portion I! thus defines an opening of substantial size at the upper end of the drier, which at all times serves as a draft outlet.

Suspended on the said members iii of the loop frame is a sheet of flexible material in the form of a curtain, indicated at it, the upper edge of which is folded inwardly on itself and stitched thereto, as indicated at 20, to form a loop hem adapted to be threaded onto the loop frame members It by merely removing a pair of adjacent terminal ends II from the sockets of the standards III. Desirably, this flexible curtain of sheet material, which may be cloth or the equivalent, is formed so that it may be extended around the entire frame structure, and thereby serve to form in effect a continuous'vertical wall constituting the closure for the drier. The upper marginal edge of the curtain preferably is cut away, as indicated at 2i, in Fig. 6, to freely accommodate the terminal portions I! of the loop frame for connection in the sockets of the standards. Desirably, the vertical edges of the curtain terminate at one end adjacent one of the standards, as seen in Fig. 3, and said vertical edges may be secured together in any convenient manner, such as herein shown, by conventional snap buttons 22.

To gain access to the interior of one end of the drier, the flexible curtain is drawn along the supporting loop frame member I, to provide an opening of suitable size. The lower edges of the flexible curtain, as seen in the drawings, terminate a short distance above the level of the floor so as to provide natural air draft for the gas burner from all directions. -By virtue of this arrangement the flexible curtain I. may be quickly and easily removed for washing or cleansing and again replaced on the frame loop I5.

Mounted on one of the standards II are one or more (two being herein shown) transversely extending substantially horizontal supports 25, which as seen in Fig. 10 are of generally tubular cross section, each formed of two sheet metal channel sections 26 and 21, rigidly secured together, as by spot welding. The members 25 are rigidly attached to an upright or standard II by a plurality of bolts 21. The lateral extent of these members or supports 25 approximately define the width of the drier structure, and carried by each of these supports are a plurality of horizontally extending transversely spaced-apart supporting elements, herein shown in the form of rods 29, each having a down-turned end portion 30, journaled in both top and bottom walls of the support 25, to provide a pivot or hinged connection which permits said rods to be swung laterally, and it is to be understood that said hinged connection is of sufllcient rigidity to properly support theweight of the rods. However, to assist in supporting the free ends of said rods in operating position, and for properly positioning the same to maintain a deflnite spaced-apart relationship to each other, I provide transversely extending supports 22 on the opposite standard It, 'at approximately the same horizontal level as supports 25. Connected to each of said supports 32 is a collar 32 adapted to be rigidly secured in proper position on the standard by means of set screws 24. Said supports 22 extend approximately the same distance on oppoflte sides of the standards, and are each formed with a plurality of transversally spaced-apart seats 25 for the free ends of the rods 29,'as seen in Figs. "1 and 8. Although I have shown two tiers of horizontally extending rods 29, which serves to support the wet or moist articles which are to be dried, the spacing of said rods desirably is such as to provide adequate air space between articles suspended on adjacent rods of each tier to insure adequate contact with the air currents for promptly and effectively drying or dehydrating said articles.

To facilitate placing articles upon the rod or removing same therefrom, when the curtain I9 is drawn to one side, said rods may be swung laterally outward about their hinge connection to the support 25, as indicated in dotted outline in Fig. 9. To limit the amount of angular swing of the rods, and also to prevent accidental removal thereof from their pivoted ends from the members 25, I provide a pair of locking bars 38 for each support 25. Said bars of each pair extend in opposite lateral directions and are each rigidly secured at one end to the standard I 0 by bolts 39. Said bars each extend over one half of the hinged or pivoted end portions of one set of rods as seen in Figs. 9, 10, 11, and have their outer ends downturned and rigidly secured to the ends of the support 25 by the screws lll. Thus, if it is neceessary at any time to remove the rods 29, the bars 38 may be quickly and easily detached by the removal of the bolts 39 and screws 40. As seen in the drawings, the dimensions of the bar capable of swinging about their pivoted connection to a maximum angle of approximately 30 degrees, and thus the other adjacent rods are limited in theiroutward swing by contacting the next outermost rod. As for example, the rod next to the outermost rod will be limited in its swing by contact with the outer rod at its maximum position of movement, and the other rods will likewise be limited.

To counteract the strains set up in the frame structure tending to tip the same over when a large number of rods 29 are projecting freely in an angularly outward direction, I provide a pair of upwardly extending trusses or brace bars 42 at the end of the frame structure carrying the supports 25. Said bars 42 are each secured at their lower ends by means of bolts 43 to the outer portion of therespective members l2, constituting the foot at said end of the frame structure, as seen in Figs. 1, 3, and 16. The upper ends of said bars converge and are rigidly attached to the upper end of the standard ill by means of a bolt 44.

Referring now to the heating element which, as above mentioned, is a gas burner, it will be noted that the burner pipe I4 is provided'intermediate its length, between the standards Ill, with a multiplicity of apertures 45- through which the gas is discharged under pressure and ignited.

One end of the burner pipe protrudes beyond its corresponding fitting II and in which end is mounted a conventional form of orifice holder 48, having a restricted discharge aperture 49. The outer end of said orifice holder is threaded and connected to a conventional coupling for attachment to a flexible conduit, not shown. It is to be understood, however, that if desired, permanent or rigid connections may be made between the threaded end of the holder 48 and the regular gaslines or pipes. The other end of said burner pipe, in the fitting H, is sealed or closed in any desired manner, as by a plug (not shown).

The end of the burner pipe I4, adjacent the discharge end of the holder 48, is provided with a pair of diametrically opposite apertures 52, lo-

cated in close proximity to and slightly forward Y of the gas supply orifice 49 for supplying air for admixture with the gas in proper proportions for insuring efficient combustion of the gas. These apertures 52. are controlled by a tubular sleeve 53 surrounding the outer end of the pipe l4, and having corresponding apertures 54 adapted to be aligned or registered with the. apertures 52. Said sleeve 53 is connected to the pipe by a pair of screws 55 extending through slots 51 in said sleeve and anchored in the fitting 48. By virtue of this connection the sleeve 53 may be rotated around the'pipe l4 for controlling the 3 effective size orifices, determined by the relation ship of the openings 54 in said sleeve, with respect to the openings 52 in the pipe l4.

Mounted above and in spaced relation to the thus avoid confinement or concentration of the heat currents. Mounted below the burner pipe is a fioor guard 62, of trough-like form of slightly greater length than the plate 60, and having its 'mately at the upper level'of the pipe l4.

marginal longitudinal edges inclined upwardly, as indicated at 83, and terminating approxi- The central bottom area of he guard member is provided with a plurality of longitudinally spaced apart apertures, 62' through which a portion of the air draft is supplied to the burner. The purpose of the angularly disposed portions 63 is to prevent accidental extinguishment of the flame b sudden or severe drafts acting directly upon the flame, and by virtue of the arrangement shown, the major portion of the air supply is compelled to travel through the restricted slots defined by the adjacent longitudinal edges of the plate and the edges of the marginal portions 63 of the member 62. This trough-like member 62 also serves to assist in directing the heat currents in an upward direction. If desired, the interior of said member 62 may be coated with any suitable heating reflective material. The plate 60 and the member 62 are rigidly secured in place with respect to the burner pipe l4 by means of bolts 65 with spacer elements 66 interposed between the pipe l4 and the respective members 60 and 62, as seen in Fig. 16.

Mounted above the plates 60 is a baflle plate 68 of generally elongated rectangular form, supported in spaced-apart relation to the member 60 by means of two pair of brackets 69 connected to the outer marginal edges of the bailie plate, adjacent the ends, by bolts 10, while the opposite ends of the brackets are rigidly connected to the pipe l4 by bolts H. The baffle plate 68 has all of its marginal edges down-turned, as indicated at 68, which tend to preclude the rapid escape of the heat generated by the combustion of the gas. The heated air between bafile plates 60 and 68 thus is admixed with the continuous supply of fresh air entering below the lower edge of curtain l9, and such admixture is substantially uniformly distributed throughout the entire cross-sectional area of the drier, withinthe enclosure formed by the fiexible curtain l9.

It will be apparent that due to the relatively large opening at the upper end of frame, as defined by the loop frameportion l5, and due to the termination of the lower edge of curtain l9 above the floor, a substantial draft is created when the burner is in operation. The natural convection currents produced by the burner thus cause a continuous influx of fresh air at the bottom, below the curtain l9, which air is admixed with the natural convection currents and circulated thereby substantially uniformly within the drier, around and over the articles to be dehydrated. This arrangement is such that the air, picking moisture from the wet or damp articles within the drier, is discharged through the large opening at the upper end of the frame, thus precluding recirculation of any appreciable amount of humid air.

To guard against any possibility of fire, due to contact with the baille plate .or the burner proper, by either the curtain or articles suspended marginal edges thereof terminating in close prox- I imity to the floor. The opposite ends of the elongated screen are rigidly secured to flanges 14 of end panels I5, which preferably are formed of sheet metal and which form a complete closure for the upper side of the burner structure. These en panels 15, as seen in Fig. 16, are provided ce trally at the lower edge with an upwardly extending notch I! for accommodating the burner pipe ll. Said panels are preferably located ad- Jacent the respective standards or uprights l0, and are rigidly secured'centraliy thereof at their upper ends, to standards by bolts II, while the lower outer ends are rigidly attached to the respective members liof the feet by bolts I and ll", the bolts 43 being of additional length for accommodating the truss members 42, as seen in Figs. 16 and 17. The end panels I5, by virtue of their connection to the foot members and the uprights It, also serve as gusset plates for enforcing the frame structure. At the end adjacent the fuel inlet,'the plate 1! isprovided with an aperture which is normally closed by a swingable plate 19, through which aperture access is afforded for igniting the burner.

By virtue of the drier construction above described it is possible to obtain a rapid drying of the moist or wet articles suspended on the rods 29, due to the fact that the natural convection currents cause an influx of a continuous and substantial supply of fresh air which becomes admixed with the convection currents and causes said admixture to intimately contact and dehydrate the articles suspended on the rods 28. The gas heater, as constructed, also insures a relatively uniform distribution of heat so as to insure substantially uniform drying of all the articles within the enclosure defined by the curtain IS. The construction of drier as herein disclosed -may be easily moved around, assembled or disassembled in a compact form for conveniencein storage or shipping.

Although I have herein shown and described a preferred embodiment of my invention, manifestly it is capable of modification and re-arrangement without departing from the spirit and scope thereof. As for example, relatively rigid sheet material may be employed in lieu of the flexible curtain l9, or electric or other heating means may be employed in lieu of the gas burner. I do not, therefore, wish to be under-' stood as limiting this invention to the precise form herein disclosed, except as it may be so limited in the appended claims.
