LAU DRY DRIER.

Application filed Jmr 14, 1926; Serial No. 115,850.

This inventionrel'atesto adrierfor use in homes and especially apartment houses for drying clothing.

The principal objects of the invention are 6 to provide a direct, untrapped', course for the damp air that collects at the bottom of a drying cabinet of this kind and direct it in a course that is always inclined upwardly, or at least level, to the fire box for the purpose 10 of evaporating the moisture inthis air and reheating it and delivering it outside the drier; and to so arranged the same that it cannot become trapped and fail to provide air to the burners. y

This is an improvement over the patent to Belding and I-Ieldman issued March 7, 1905, No. 784,026,and involves the use of a gas radiator connected as stated above and employing several of the principles of said patent. Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing which is a perspective view of a drying cabinet partly broken away to show the features of this invention.

I use the ordinary cabinet 10 in which the clothing is hung on sliding racks 11, as is well known in this art. At the bottom, and preferably at the front, is a fire box 12 heated by gas burners 13 and having'a longitudinal opening 14 at the top and a narrow longitudinal opening 15 at the bottom of the rear wall. The air in the fire box is conducted directly from the opening 14 to a duct 16 extending across the cabinet near, but above, the bottom at the front. This duct is connected by a series of flues 17, which preferably are horizontal and straight, to discharge into a transverse duct 18 at the rear. This duct discharges at the end through an outlet, either into theouter air, or up through a pipe 20 to a flue in the building. 7

It will be observed that the fumes pass through these flues and ducts without any chance of escape into the air of the chamber or cabinet 10. In other words the clothing is heated entirely by radiation, as in said patent. I have preserved that feature.

Now it will be understood that the air which enters the cabinet comes in independently of the heating system, in any desired way, and that the heated air necessarily rises and expands and forces down the cold and moist vair which has been in circulation 5 through the damp clothing above. This cold air necessarily collects at the bottom. For the purpose of taking it out of the cabinet and supplying oxygen to the burners, I provide a damp air intake 21 located along or near the fioorof the cabinet. This isv inclined upwardly through part or all of its length and never downwardly. It is C011 nected with the opening 15 and on account of the draft created by the burners, it is drawn into the fire box, reheated, deprived of .its moisture, and the products of combustion or fumes led out through the ducts and flues and discharged from the cabinet at the outlet 19. In other words this damp air is not in any way in danger of being trapped on its way to the fire box, which in case of a defective flue might choke the whole radiator and smother the gas because it would not get the necessary air for combustion.

It'will be seen that, as in the above patent, I still bring the foul damp air from the cabinet back to the fire box and consume it. This radiator will operate perfectly without any flue connection.

The improvement over the said patent consists largely in the fact that the air is drawn into the fire box directly from the floor and also in the fact that there is no change in the direction of flow of the damp air to the fire box which might form a trap in the case of a defective flue in the building. This constitutes an important improvement, particularly in the cases in which the fiue is not large enough and in which there is no flue in the building to re ceive the products of combustion from the outlet 19.

Although I have illustrated and described only a single form of the invention and shown it as applied to a particular form of laundry cabinet, I am aware of the fact that modifications can be made therein by any person skilled in the art and that it can be applied to other types of drying cabinets, without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited in these respects, but what I do claim is 1. In a laundry drier, 'the combination 105 with a gas heated fire box, cross ducts at the :front and rear, into the front one of which the box delivers the fumes and a series of horizontal fines connecting the tWo ducts and conducting the fumes from one to the other, of a damp air intake having its inlet near the fioor of the drier under the fines and conducting the damp air from the bottom of the drier near the center thereof into the fire box below the burners therein and below one of said cross ducts.

2. In a laundry drier, the combination With afire box at the front, ducts at the front and rear, into the front one of which the firebox delivers the fumes, and fines connecting the tWoducts, of a damp air intake having its inlet near the center of the floor of the drier extending under the front box substantially horizontally and discharging them out of the cabinet, and an intake extending across'the bottom of the cabinet at a distance from the fire box for collecting the: damp air and leading, it substantially horizontally into the bottom of the fire box, for the purpose described."

In testimony whereof I aflixed my signature.
