Application `filed February 4, 1.918. Serial No. 215,303.y

To all whom ,it may concern: f

Be it known that I, ROBERT L. LUND, a citizen of vthe United States of America, a resident of the city of St. Louis, State of Missouri, have invented certain new and use-- ful Improvements iny Driers, `,of which the following s a full, clear, and eXact description, Vreference being had to the accomspecication. l

My invention relates to improvements in driers, and more specifically stated to a heating device adapted for use in drying shoe` soles .for whatever purpose it may be necessar .gne of the objects of the invention is to provide a. simple and efficient means whereby articles, such as shoe soles, can be quicklyland thoroughly dried without the danger of overheating the articles and without scratchingor `otherwise marring them. Another object is tof enable Vtheshoes to be easily and quickly positioned `on the drier, thereby4 saving considerable time in` dryving large numbers of shoes, and at the same time enabling each shoe to be properly positioned relative tothe heating element.

tWith-fthe,foregoing and other objects in view theinvention comprises thenovel construction, combination and arrangement of parts hereinafter more speciiically described and'illustrated in the `accompanying drawings wherein is shown ,the preferred em-` bodiment ofthe invention; however, it is to y Vbe understood.l that the yinvention comprehends changes, variations andinodiications which come within the scope of the claims hereunto appended.

Y Figure I is a top or plan view of a drier constructed in accordance with the' invention, a portion of one of the pads or seats being broken away to show the sheet metal heat transmittingv member.

Fig. II, is an inverted plan view ofthe drier.

Fig. III is an end view.y

. Fig. -IV is a transverse section.

Fig. V shows a heating device conforming to the curvature of the shoe'sole.

To illustrate the invention I have show two drying devices A and A arranged in the form' of steps so that shoes or other articles to be dried can be easily placed upon both of the devices.v Each ofthe devices A and A comprises a sheet metal heat transmitting member l having its margins 1 turned soles are seated.

Heretofore, shoe soles have been dried by downwardly and inwardly (Figs. II and IV) to form a heating chamber, an electrical heating element such as resistance wires 2 arranged in said heating chambeiga sheet of heat insulating material 3, preferably asbestos, arranged below the electricalheating element, and a pad 4 covering the top face of the sheet metal heat transmittingmember l. Eachv pad 4 is preferably a sheet of felt or other suitable fabric, having its rear margin'v folded under and secured by means of an angle bar 5 as shown in Figs. IIand IV, thefront margin being folded partially around and secured by

rods

6 and 7 in front of the heating chamber. Cross bars 8 (Fig.

are secured under `each sheet of insulatinof material 3.

Y Ehe ends of the drying devices A-A are connected together by means Vof diagonal members 9. Each drying device is also provided with a stop rod l0 arranged over its pad 4 andsecured to brackets 12 which eX- tend upwardly from the ends of the heating chamber. Each stop rod 10 `is preferably covered bya pad 10. The heating element of each drying device is provided with a pair of binding posts 13 and wires leading therefrom to a switch 14, which may` be operated to'control the flow of electricity to both of theelectrical heating elements.

Itk will now be understood that each drying device preferably comprises an electrical heating element confined between afsheet of asbestos 3 and a sheet metal heat transmitting member l, the latter being covered by a Vpad 4.y The pad prevents the shoe soles from being overheated by the electrical heater, at the same time enabling the shoes to be quicklyv placed upon and removed from the drier without scratching the bottom faces of the soles. As a further means for increasing the speed of the operator, the padded stop rod 10 is secured over the pad 4 so as to cooperate with the shoe uppers as shown in Fig. IV, thereby enabling the shoes to be quickly and properly located on the pad 4. The shoe soles are quicklyand thoroughly dried by the action of the heat transmitted through the pad 4 upon which the using a large heating chamber open at the top for the discharge of hot air to the shoes. A screen, or the like, is usually arranged over the open top of the heating chamber so as to support the shoes in the course of theA rising het air currents. The shoes are separated from each other and arranged over the heating chamber in a somewhat disorderly manner. Obviously, the rising hot air can escape freely around and between the shoes, and the action of the heat is not concentrated on the soles of the shoes. In using these earlier driers, a very large per.- eentage of the heat is dissipated, or wasted, by passing freely from the heating cham" ber to the atmosphere.

In accordance with the present invention, the sheet metal heat transmitting memberl is exposed directly to the heat generated 1n the heating chamber and the heat is transmitted, by radiation, from the metal to the soles of the slices. Instead of being carried away freely by rising air currents, the heat radiating from the metal is transmitted d1- rectly through the thin pad 4 to the soles of the shoes. The action of the heat is thus very effectively concentrated on the soles of the shoes.

The drier produced by the combination of elements herein shown is a relatively small apparatus, but it will hold a large number of shoes, arranged compactly and in an orderly manner so they can be conveniently reached by the operator.

In Fig. V, I have shown a heating chamber 20 Ahaving its upper portion curved to conform approximately to the curvature of the bott-om face of the shoe soles. This curved portion is covered by a thin pad 21 which forms a seat for the shoes. By forming the drier in this manner the entire bottom face of the shoe sole will contact with the pad Q1, and the heat will be transmitted from the pad directly to the shoe sole, without having an opportunity to escape into the atmosphere.

I claim 1. A drier comprising an electrical heating element, a heat transmitting member covering said electrical heating element, a pad covering said heat transmitting member and forming a seat for the articles to be dried, and a heat insulator covered by said electrical heating element, the latter being confined between said heat transmitting member and the heat insulator.

Q. A shoe drier of the character described comprising a heating element, a heattransmitting member covering said heating element, a pad covering said heat transmitting member and forming a seat for the soles of the shoes to be dried, and a stop arranged heat Y transmitting member covering said electrical heating element, a pad covering said heat transmitting member and forming a seat for thc soles of the shoes to be dried, and an elongated padded stop bar secured over said pad so as to cooperate with the uppers of the shoes in determining the positions of the shoes relative to said pad.

4. A shoe drier of the character described comprising a plurality of shoe receiving devices arranged in a stepped relation to each other, each of said shoe receiving devices comprising a pad forming a seat forv the soles of the slices, a sheet metal heat transmitting member covered by said pad, a heating chamber being formed below said sheet metal heat transmitting member, and a heating device confined in said heating chamber.

5. A shoe drier of the character described comprising a. plurality of shoe receiving devices arranged in a stepped relation to each other, each of said shoe receiving devices comprising a pad forming a seat for the soles of the shoes, a sheet metal heat transmitting member carried by said pad, a heat insulator below said sheet metal heat transmitting member, an electrical heater conlined between said pad and the heat insulator, and an elongated stop member secured over said pad to limit the movements of the shoes seated on said pad, and' diagonal connecting members securing the ends of each of said shoe receiving devices to the adjacent shoe receiving device,

6. A drier comprising a housing, an electrical heating element in said housing, a pad covering the top of said housing and forming a seat for the articles to be dried, and a stop secured above said pad to limit the movements of said articles.

7. A shoe drier of the character described comprising a sheet metal heat transmitting member having its margins turned downwardly to form a heating chamber, an electrical heating element confined in said heating chamber, a pad made of sheet material covering said heat transmitting member and forming a seat for the soles of the shoes, margins of 'said pad being turned downwardly and secured, supporting brackets extending upwardly at the opposite ends of said heating chamber, and a stop rod arranged above said pad and having its ends secured to said supporting brackets so as tecoperate with the shoe uppers in limiting the movements of the shoes supported on said pad.

In testimony that I claim the foregoing I hereunto afiX my signature. i
