Application Afiled August 29; 1919. i Serial No. 320,645.

Be it known that I, NiivuJ :MONROE H01L..

it is desirable and important, .both to the life of the shoes and the health of the person wearing the same, that the shoes be promptly dried and waterproofed before use thereof is continued. The main object of the present invention is to provide for quickly drying and waterproofing damp or wet shoes while retained on the feet of the wearer thereof, and for accomplishing this with the convenience, facility and expedition of an ordinary boot-blacking operation.

The accompanying drawings illustrate 'what l now believe to be preferred embodiments of apparatus of the present invention fi'apable of accomplishing the aforesaid and other objects, as will more fully appear from the detailed description.

modified Referring more particularly to Figs. l, 2

and 3, which disclose a portable device adapted to be carried about by itinerant op" craters, on the top of the casing 10 are secured the Vhoods l1 shaped to receive the shoes to be treated whileI on the feet of the wearers. The hoods are sufficiently large to form spaces around the front part of the shoes and over their insteps, through which air may beepropelled for drying purposes. llVhen in position in the hoods, the balls of Athe feet rest upon the ynotched plates 12 carried by thebars 13 extendingacross the upper* part of the casing,y the notches in the plates permitting a free passage of air beneath theshoe-soles. The heels. rest on the ysupports 14 pivoted lto the back of the casing and when not in use these supports can be turned out of the-way against the back of the casing as indicated by dotted lines in Fig. 3.

Extending across the upper part of the casing 10 is the horizontal partition 15 forming therein an air-chamber'lG open to the under sides of the hoods 11. With this air-chamber communicates the blower-casing 17 in which is mounted the fan 18. Opposite. the outlet 19 of theV blower-casing Vis the deflector 20 to direct theincoming air into bothsides of the air-chamber 16 beneath the hoods. Communicating with the inlets .21 in the side of the blower-casing is the conduit 22 leading from the chemical heater 23 mounted on the top of the main casing 10 between the toes of the hoods 11.

i The conduit leads from the lower end of the lindrical casing 24 fixed to the top of the main casing 10 and is provided with a linmg 25 of heat-insulating material. Removably contained within the cylindrical casing is the'foramin'ous cylindrical holder 26 separated 'from the lining 25 byan annular space 27 communicating at the lower rear end of the heater with the lconduit 22. The holder 26 i'.s adapted to contain a mixture of granulated charcoal and saltpeter, or other suitable fuel. This fuel is preferably prepared in the form ofV cartridges to facilitate the loading of the holder. As the holder is removable, it can be readily displaced to discharge the ashes of a burnt cartridge and to receive a new one. The upper end of the cylindrical casing 24 is provided with a cap 28 that can be removed to admit air to support the combustion and to supplyheated air to the conduit 22 when the fan 18 is in motion. When the cap is replaced, air lis excluded from the heater and the combustion is suspended. The nature of the fuel is such that the combustion smolders Awhen air is excluded, but will fiare up on the admission of fresh air so that rekindling will not be required for each operation.

The fan 18 is carried by the shaft 29 journaled in suitable bearings in the blowen casing 1T. On an end of this shaft is a pinion 30 meshing with the gear 31 driven by the spur 32 engaging the gear 33 on he shaft 34 rotatable by the crank lVhen the crank-shaft 34 rotated, through the intervening` gear-train, the fan 18 is driven to propel air through the foraminous holder 26 of the heater the cap 28 being removed), the annular space 27, the conduit 22, the blowercasing 17, and the outletl 19 into the air-chamber 16.

ln the operation of the drier, the wearer of the wet shoes thrusts his feet into the hoods 11 and the operator turns the crankshaft 29 to propel heated air into the chamber 16 as has been described. The heated air first inipinging on the wet soles quickly dries them, and then passing upwardly in the hoods dries the uppers. The air is projected with considerable force from the rear openings of hoods 11 around the heel portions of the shoes and dries these also.

Means are provided whereby the soles can be impregnated with a waterproof composition after drying. Mounted in the main casing 10 is the reservoir 36 to contain any suitable waterproofing composition in a liquid forni. Leading from the lower part of this reservoir is the supply pipe 37 communicating with one end of the rotatable tube 38 extending horizontally across the air-chamber 16 between the foot-rests 12 and slightly below the same. Entering the other end of the tube 38 is the pipe 39 leading from the air-pump 40 suitably mounted on the casing 10. The pipe 39 extends to the opposite end of the tube`38 and is closed at its inner end. The pipe 39 is in sections which are connected together by the coupling 41 (Fig. 4) so that the section traversing the tube 38 can be turned relative to the other section, which is fixed. The coupling 41 also furnishes a closed bearing for the adjacent end of the tube 38. The other end of the tube 38 has a similar coupling 42 with the end of the fixed pipe 37 leading from the reservoir 36. By means of the couplings 41 and 42, the tube 38 and the inclosed section of the pipe 39 can be turned on their longitudinal axes relative to the fixed pipe 37 and the fixed section of the pipe 39. The tube 38 has a radial arm 43, which is connected by the link 44 with the crank-arm 45 on the inner end of the shaft 46 ournaled in the wall of the casing 10. On the outer end of shaft 46 is the knurled finger-piece 47 by means of which the shaft can be turned and, through the intervening mechanism, a rocking motion imparted to the tube 38.

At each end of the tube 38 is a nipple 48 leading from the annular space 49 between the tube and the inclosed section of the pipe 39. lVith the nipple 48 registers a second nipple 50 on the inclosed section of the pipe 39 and leading from the interior of the latter. The two nipples are spaced apart to form an annular exit between them from the annular space 49 between the tube and pipesection. As the inner nipple projects into the outer one, when the tube 38 is rocked the inclosed section of the pipe 39 must rock with it.

Each pair of nested nipples 48, 5() form a spraying ejector. lhen air is forced outwardly through the two nipples, a suction is created in the annular space between the two and this draws through the tube 38 and the pipe 37 the liquid from the reservoir 36 to spray it into the air-chamber 16. The ejectors are so located as to be directly below the soles of the shoes placed in the hoods, and as the tube 38 is rocked the liquid is sprayed over the entire under surface of the soles. lhile the liquid is particularly directed toward the sole of each shoe, yet as said liquid is atomized to a considerable ex tent some of it will rise in the hood and be deposited on the upper part of the shoe to lightly waterproof the same.

After the soles and uppers of the shoes have been thoroughly dried, the operator ceases turning the fan 18 and with one hand operates the air-pump 40 to force the waterproofing composition through the ejectors and with the other hand turns the [ingerpiece 47 to rock the ejectors so that composition will be sprayed over the entire under surface of the soles. During the drying process, the leather of the soles is heated and its pores are opened through the eXpulsion of the moisture therein. The slight amount of moisture that remains in the leather is in a vaporized condition and, when cooled by the application of the spray, this moisture is condensed and produces, to some extent, an inward suction in the individual pores. This suction aids the capillary attraction of the pores in the absorption of the waterproofing composition by the leather.

The operation of the .machine is simple and can be readily handled by the ordinary boot-black, and it can be carried around by him in place of his ordinary blacking kit during rainy weather. The drying of the soles is quickly accomplished and the water proofing composition can be applied in a few minutes.

The machine has been previously -described as a portable device; it can also be established as a fixture in boot-blacking places, barber-shops'and the like. VWhen so established, several additional features can be added that would be `too weighty for a portablefkit.

Referring to Fig.l 5, which shows a modifi# cation of the operating mechanism, on the crankshaft 34', which drives the gear-train that rotates the fan, ris the eccentric 51=car rying the strap l52.y A link 53 connectsthe strap on one side withfthe piston of the pump L10 `that forces air through'the pipe 54 into the reservoir 86Y containing the ww terproofing fluid.. From the lower part' of the reservoir, the pipe 55 leads to the rotatable tube 38 having nipples 48, as in the first instance.v- This tube 38 is rocked by its connection through the arm 55 and the link 56 with the eccentric strap 52. As the eccentric rotates, the strap is reciprocated to rock the tube 88 and to move the piston of the pumpl 40".' Astlie tube and piston connections are on opposite sides of the strap, their operations will be balanced to some extent. f f f Meshing with vgear 33 on the crank-shaft 34 is a somewhat larger gear 57 fixed on the worm-shaft 58 driving the worm-gear 59 on the shaft 60 journaled in suitable bearings y(not shown).` On one side of the worin-gear 59 is a cam 61 toengage, during the rotation of `the worm-gear, the lever 62 to open the valve 63 in the supply pipe 55, said valve being normally closed by the spring 64. Then the valve is opened, the airpressurein the upper part of the reservoir 36 forces a charge of waterproofing fluid through the supply pipe 55 into the tube 38 and through the nipples 48 onto the soles of the shoes during the rocking of the tube." The interval during which the valve 63 is heldopen depends on the length of the cam 61, andthere will be one actuation of the valveV during onerotation of the worm-gear 59. However', there may be more than one cam to open the valve more frequently should it be deemed necessary.

In Fig. 6 another modificationis shown in which -tlie chemical heater of the first described embodiment is replaced by an electric heater, in which an electric motor is provided for driving the blower, and in which any adjustable setting device is provided for actuating the valvein `the fluidsupply pipef In this embodiment, the fan of the blower 18" is driven by the electric motor 65, the blower communicating through the conduit 22 with the air-chamber beneath the hoods.` Into the blower 18 leads the pipe 66 from the hollow casing 67 in which is mounted the heating coil 68 electrically connected with the generator 69. Instead of the direct generatorconnection, a plug connection 70 may bensed for the ordinary lighting system. Also, the circuit through the coil maybe controlled by an ordinary coin -in -the slot mechanism 71. With the current on 1n the coil 68, air is drawn through the Casin' 67 where it isY C) 3 heated, by the blower, and is propelled through the conduit 22" to the air-chamber beneath the hoods for drying purposes, as in the first embodiment. On the shaft 72 of the blower 18 is the worm 7 3 engaging the gear V74 fixedon the shaft 75 carrying a wormf76 engaging the gear 77. Through the connection 78, the air-pump 10 will be actuated as in the previous instance. On the shaft 79 is thecsleeve 8O having a frictional engagement with the gear 77 to turn with the latter on said shaft. On the sleeve 80 is a hand to coperate with a suitably fixed dial (not shown), and on the other end of the sleeve isa cam-arm 81 to engage the arm 62 of the valve in the fluid-supply pipe 55. By adjusting the sleeve 8() in the gear 77, the cam-arm 81 can be set to engage the arm 62', at any predetermined point in the rotation of the gear 77, to open the valve in the fluid-supply pipe 55.

In Fig. 7 is shown an embodiment of the invention including a. coin-controlled device whereby the customer can operate the machine himself. The operative parts of the machine are driven by the crank-shaft `311 adapted to be turned by the cranks 35 in the hands of the customer. The rotation of the crank-shaft is controlled by the coin dropped into the slot S as is usual in such machines. Y

In Figs. 8 and 9 a further embodiment of the invention is disclosed. In this instance, a suction-fan 82 is driven by an electric motor 88. Leading to the inlet of the fan is the flexible tube 84K connected to the stiff hollow handle 85 carrying the suction-cup 86, which coimnunicates through the hollow handle and flexible tube with the inlet to the fan. Across the mouth of the suctioncup extends the grid 87 connected by wires 88 with any suitable source of current, the grid being made of conductive material and suitably insulated from the wall of the cup. lith the suction-fan in operation and the grid heated by a suitable current passing therethrough, the suction-cup is moved back and forth across the wet sole to dry the same, the heat from the grid vaporizing the moisture in the leather so that it can be withdrawn bythe suction.

Attached to the suction-cup is the reservoir 89 carrying the waterproofing fluid, which is fed therefrom by the wick 90. As the suction-cup is moved back and forth across the sole, the projecting end of the wick contacts with the leather and applies the fluid. On the upper end of the reservoir is a guide 91 to bear against the sole to protect the wick.
