LAUNDRY DRIER.

Application filed April 2'7, 1925. Serial No. 25,983.

To all whom it may concern:

Be it" known that I, JAMES J. TAYLOR, a citizen of the United States, and residing at Wyoming, in the county of Hamilton and State of Ohio,'have invented a new and useful Improvement in Laundry Driers, of which the following specification is a full disclosure.

My invention relates to a laundry drier and the object of the improvement is to simplify the device to a structural minimum and at the same time to increase the heating and drying efliciency by a particular manipulation of the products of combustion in relation to the dryin compartment and the conduits for intro ucing-the air currents into the drying compartment,

The features of the invention are more fully set forth in the description of the drawings forming a part of this application, in which:

Fi re 1 is a front view of my improved laun ry drier with certain parts broken away to show the inner construction.

Figure 2 is a fragmentary end view show ing the opening through which the heating chamber or unit is inserted into the base of the drier.

Figure 3 is a plan sectional view taken on 1ine33, Fig. 1, showing the corner construction and the screen.

Figure 4 is a sectional view taken on line 4-4:, Fig. 1.

Figure 5 is a sectional view taken longitudinally of the heating chamber at the burner end thereof.

Figure 6 is a plan sectional view taken on line 6-6, Fig. 5, showing the arrangement of the inlet tubes and the partitions for directing the heated air around the tubes.

Figure 7 is a sectional view taken on line 7-7, Fig. 6,

Figure 8 is a fragmentary end view, taken the same as Fig. 2, showing the heating a 0 v i The invention hereln disclosed ma conveniently embodied in the conventional design of laundry drier as regards material and general structure, which, as disclosed in the drawing for illustration, comprises a sheet metal box or cabinet 1 constituting the drying compartment provided with the usual hanger. racks 2, the air outlet 3 at the upper ,end of the compartment and communicating preferably with the flue pipe 4 which leads upwardly from the combustion detailing the tube construction.

chamber at the bottom of the compartment. The usual doors 5 are provided and the usual horizontal screen 6 is placed at the base of the drier compartment, for preventmg any clothes touching the. heater unit if accidentally dropped from the racks.

The heater chamber 7 is immediately below the drying chamber and corresponds therewith in area. This chamber is constituted by the walls of the structure, the upper horizontal plate or sheet 8 and the base plate or sheet 9 positioned slightly above the floor, theentire .device being supported w1th1n the frame of the drier so that there is an air space extending completely under the heating chamber.

This heater chamber 7 may be regarded as comprising the burner chamber 11 and the communicating air heating or heater chamber 12 which lies intermediate the burnerchamber and the flue pipe 4:. The burner chamber is separated slightly at its her by means of the low vertical partition 18 allowing the products of combustion to flow upwardly and over this partition. and

.lower portion from the air-heating chaminto the first quasi-compartment of the air- I heating chamber. This air-heating chamber'is for the purpose of utilizing the products of combustion for heating the air which is to be admitted into the drier, and this function is provided through the placing, in the airheating chamber of a series of vertical air tubes l t -which extend through the top and bottom plates 8, 9, so as to pass air from the room through the heater chamber and into the lower portion of the drying compartment.

- These vertical air tubes are preferably arranged in parallel horizontal rows, separated by a series tively to the opposite end or'side walls of the structure, thus providing alternately of partitions 15 which are alternately secured at opposite ends respec:

.tion move through the left-hand passage and then flow to the extreme right and out the passage, at the other end into the next subdivision and so on, which of course provides for the escaping products of combustion along this pathof travel, possible within the limitations of the air-heating chamber and from which it results that the greatest maximum heating efficiency of the products'of combustion is imparted to the walls I of the air tube.

From practical experience I have found that the heating of the tubes is facilitated by providing in addition to the alternate transverse passages or zigzag general direction of travel of the products of combustion, additional air passages in the nature of orifices 17 placed at appropriate in tervals in these partitions, as shown in Figs. 7 and 6, which permits of minor 'or intersecting currents of air passing around and in contact with the air tubes.

While it is not essential to the principles of this invention, I have found that in a" structural sense and in an assembly sense, it is desirable to constitute the unitary burner and air-heating chamber in the nature of a removable drawer, as shown in Figs. 1 and 2. -This may be done by forming the flanges 18 at the bottom of the casings forming a rest for the heating chamber drawer and in which event the inside end of this drawer adjacent the flue pipe would be formed with a flanged annulus 19 for fitting air tubes in relation to the top and bottom plates or sheets which construction, illustrated in Fig. 7 is very desirable in such cases as where I employ the other preferred though optional embodiment, namely, of making the burner and air-heating chamber a unit in the nature of a removable drawerfitting into the general drier casing. To effect this rigidity, I preferably provide the registeringorifices in the top 'and'bottom plates respectively and so form these orifices that I strike annular flanges 26, 27 upwardy and downwardly from the plane of the top and bottom'plates respectively so that they project beyond the plates, forming securance collars or annuli for the vertical a11- tubes.

Accordingly, the upper and lower ends of these vertical tubes extend beyond the extremities of these annuli 26, 27, and are preferably bent over to form the cupping annular flanges 28 inter-engagin or interlocking with the annuli 26, 27. mmediate- 1y adjacent the top and bottom plates, respectively, I preferably provide the annular tubes with the bead extensions 29 which reinforce these plates transversely, thereby adding to the rigidity, and the whole structure is extremely compact and stiffened, inasmuch as the tubes are thus secured to the top and bottom plates between the beads 29'and the annular cups 28.

While I have shown the several preferred embodiments as illustrative of the best method of carrying out the invention, it is obvious that these may be modified or omitted without departing from the scope of the disclosure except in so far as such preferred constructions are made the subject matter of the specific claims.
