SHOE-DRYING ATTACHMENT FUR SOLE-SEWING MACHINES.

menses.

To all whom it may concern 7 Be it known that 1, JAMES BADLAT, a citizen of the United States, and resident of Des Moines, in the county 'of'Polk and State of Iowa, have invented a certain new and useful Shoe-Drying Attachment for Sole- Sewing Machines, of which the following is a specification.

The object of my invention is to provide a shoe drying attachment for soling ma-- chines of simple, durable and inexpensive construction.

A further object of my device is to provide a drying rack adapted to be operated by the steam generated from the steam generator of sole sewing machines. In this connection it should be mentioned that the sole sewing machines, which are in common use in repair shops are provided with steam generators, which are connected with the waxing device in the machine, so that the wax may be kept warm'and in a semi-fluid condition to properly wax thread sewed through the soles. It should also be explained that it is the custom to temper leather, which is formed into the half soles, which are used for repairing. This tempering process consists of soaking the leather in water, so that it becomes sufiiciently pliable to be readily handled in the process of half soling shoes. When, however, the leather becomes so soaked it is desired to finish off the edge of the sole and to black the edge, it is found that the wet leather has a tendency to fray, sothat it is impossible to put a smooth hard finish on the edge of it when one attempts to finish the edge of the sole, while it is still damp.

A further disadvantage results from the attempts to finish the edge of the sole during the time that it is still damp in that the damp leather damages the sand paper, which is used for buffers, so that almost three times as much sand paper is worn out where the buffers are used with the damp leather as is the case where thebufi'ers are used with dry leather. My invention, therefore, consists of providing means for drying the soles rapidly and conveniently as they are finished by the sole sewing machine, so that by the time that the operator is ready to proceed with the edge finishing. process the sole may be sufficiently dry to admit a smooth finish without excessive wear on the sand paper of the bufiers.

A further object of my invention is to Specification of Letters Patent.

provide a steam coil having a drying rack disposed thereabove and to connect the steam coil with the steam pipes of the Wax heating system of the sewing machine whereby the drying rack may be operated without additional expense. 7 lVith these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawmgs, in which 2 v Figure 1 shows a side elevation of my improved drying rack and its connections with the sole sewing machine and generator the outline of the former being shown in light.

lines, and

Fig. 2 is a top or plan view of the drying rack itself.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate generally the base of a sole sewing ma-. chine having the sewing mechanism inclica-ted generally by the numeral 11. A steam generator 12 is provided as a part of the equipment of this machine and is operatively connected with the wax heating portions thereof'by the pipes 13 and 14.

My invention consists in connecting to these pipes 13 and 1a a steam drying rack, which is so placed that the shoes, which have been passed through the machine 11 may be conveniently thrown upon the drying rack to be dried while other shoes are being operated upon by the machine 11. The cross slats 21 and the longitudinal slats 20 must be formed from some non-conducting material such as wood in order that the leather may not become burnt from the heat from the coil. Experience has shown that warmed metal will burn the leather very much more quickly than will wood or similar material, which does not conduct the heat readily, so that the drying frame should be composed of such a non-conduct ing material and so shaped that shoes thrown thereupon will not be burned and the life thereby taken from the leather.

My drying rack consists of a base 15, which as shown is secured to the floor by a floor flange 16 and having at its upper end a'second floor flange 17. A U-shaped strap iron member 18 has its central portion secured to the floor flange 17 and its ends Patented Nov. 1, 1919. v Application filed September 4, 1917. Serial No. 189,496.

turned upwardly.) The ends of the member 18 support a horizontal drying rack 19',

which consists of longitudinal slats 20 between which. extend a plurality of spaced parallel cross slats 21. A steam coil, which rests upon thecentral portion of the mem. ber 18, consist's of a plurality of spaced parallel steam conducting pipes 22, which are suitably connected together at their ends by meansoi elbows 23. A supply pipe 2% the drying rack is installed to the right, of

and in line withthe machine 11, so that as soon "as the soles have been sewed to the shoes onthe machine 11, the shoe may be thrown onto the rack where it will bedried from heat of the steam coil." It may be sug' gested in this connection that experience has demonstrated that the heat of approxi-. mately 125 degrees is best suited for the drying of the shoe leather as at this heat there is no tendency to burn the leatherand yet a sulhcient heat is produced to cause the il'noisture therein to evaporate. V The coils may besuggested that the further advantage herein disclosed are substantially of such size relative to the capacity of the generator that they will permit very closely the desired degree of heat but in order to insure this result I have provided .a control valve f 28, which is disposed in the supply pipe of the steam coil. 7

By this means the heat supplied by the drying rack may be accurately gaged. It

I resides from'this particular heat that the drying rack does not furnish sufficient heat to materially change the temperature of the room in which it may be installed, although it furnishes suificient heat to dry the sole of shoe enough, so that it may be finished on the finishing machine while the sole of the other shoe is being sewed on the sewing machine. The sole of thesecond shoe may then be dried on the drying rack while the first shoe is being put through the finishing process, so that there is no necessity for delay due to the drying of the soles upon my drying :rack, and so that they may be nicelyfinished at their edges without undue wear on the sand paper of the buffers. It should also be suggested that my improved drying rack may be installed at a very slight cost and there is no operating expense connected therewith underordinary circumstances, as the steam generator of the sole sewing ma chine does not costany more to run when operating the drying rack than when its steam is merely directed into the wax heating mechanism' of a sewing machine.

I claim as my invention:

1. In a device of the class described adapt- 7 ed to be connected into the steam heating system of a shoe sole sewing machine, a dry ing rack compr sing a vertlcal uprlght, a fittlng. at the lower end thereoi adapted to be secured to ,a floor, a fitting at the upper end of the uprlght, a U-shaped member hav- 1ng 1ts central-portion secured to the fitting and itsend portions extended upwardly to' form supports, a pair of horizontally alined spaced parallel slats mounted on the sald end portions, a plurality of spaced parallel cross slats being composed of material which does not conduct heat, a plurality ofspaced parallel tubes of heat conducting material communicatingwith each other and supported by'the central portion of the U shaped member in position spaced a predetermined distance below the cross slats, and means'for operatively connecting said tubes with the heating system of the sewing machines.
