METHOD OF PROTECTING SHOES DURING TOE SOFTENING.
Application filed August 6, 1919. Serial No. 315,658.
To all whom it may concern Be it known that I, JOHN B. HADAWAY, a citizen of the United States, residing at Swampscott, in the county of Essex and State ofMassachusetts, have invented certain Improvements in Methods of Protecting Shoes During Toe Softening, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. i
In the manufacture of boots and shoes, it is customary to subject the toe portions to a softening process, the usual method being to insert the toe portions of the shoes, while in an incomplete state of manufacture, into what is termed a steamer. 1 Frequently the insoles or the box toes, or both, are. overheated, or burn, owing to a too high temperature in the steamer or tosubjecting the shoe to unduly long steaming.
This difficulty exists particularly in the manufacture of shoes which employ what are known as manufactured insoles such as leatherboard insoles, and wherein a fabric consisting of canvas or duck is adhesively connected with the insole to reinforce it. When the toe portion of such a shoe is subjected to the action of steam for softening purposes, the treatment tends to have a marked disintegrative effect upon the stock or the adhesive and so to affect the insole and its reinforcing layer that later, when the toe portion of the shoe is lasted, the wiping-up action of the toe wipers is liable to-turn up the edge of the feather of the insole. Sometimes also the sewing rib is forced back as the result of the action of the toe wipers.
A particular object of the present invention is to prevent any undue softening of parts of the shoes which might be affected by the action of the softening agent, to pre-' liability of those portions being disvent torted or otherwise damaged.
This object I attain by the method of applying a coating of heat-resisting material to theportions of the shoes to be protected, preferably before completion of the lasting operation, so that when said portions are subjected to the action of the softening agent prior to completing the lasting of the shoe the protected portions will not be so softened as to interfere with proper toe lasting.
In order to explain my invention, refer-' ence may be had to the accompanying drawlngs, in which,
. Fig.1 is a perspective view of an incomplete shoe as it appears during the step of applying the coating;
Fig. 2 1s a perspective View of one form or type of steamer, with a shoe in position to have its toe portion subjected to the action ofthe steam;
Fig. 3 represents a vertical section through.
the toe portion of a shoe and also a portion of the steamer;
Fig. 4 is a sectional view illustrating the utility of the invention in connection with the lasting operation. i i
The hood of the steamer. is indicated at 5 in Fig. 2, the front portion 6 thereof being cut away to form recesses 7 which recesses are adapted to be occupied and substantially filled by the toe portions of shoes carriedby lasts 10. .To support the lasts with the foreparts thereof in the steamer, a suitable bracket is provided as indicated at 8.
When the last 10 has had the upper 11, an insole 12, and the cap 13 and box 14 fitted and located thereon in the usual manner, such as indicatedin Fig. 1, a moisture and heat resisting compound is appliedto all of those portions of the shoe parts which are liable to be injuriously affected when applied to the steamer for purposes of softening the toes. .Such coating will usually be applied by means of a hand brush as indicated in Fig. 1.
In Fig. 4 of foot of a lasting machine is illustrated at 15, one of the toe wipers at 16 and the toe rest at 17. j
A shoe of the particular type the manufacture of which is improved by my invention includes an insole 12 of such composition as leatherboard, there also being a top facing or sock lining indicated at 18. The sewing rib 19 frequently comprising a piece of tape double stitched in place, is covered by a layer 20 of material ,such as canvas or duck which is adhesively connected to the surface of the insole 12, the reinforcing material extending over said rib.
When a shoe of the character described the drawings the hold-down fibre or asbestine.
.is being toe lasted, it is held between the foot 15 and the toe rest 17 while the toe wip: ers operate in the direction of the arrow in Fig. 4:. When such a shoe has been subjected to the action or" a steamer as heretofore the feather of the insole and sometimes the rib 19 are distorted by the action of the toe wipers. When, however, the portions which it is necessary to protect have been coated as indicated in Fig. 1 and as hereinbefore described, the parts so coated are suf ficiently protected from the moisture and heat of the steam to remain sufficiently rigid to oppose distorting or displacing action of the toe wipers.
While I do not limit myseli to any specific moisture and heat resisting composition or coating, a suitable compound may consist of a soapy emulsionoi a wax or Wax-like mixture carrying in suspension some heat resisting or insulating substance such as asbestos This coating is applied'by means of a brush to whatever portions of the shoe it is desired to protect,- but especially to the insole. The coating is applied thickly enough so as to protect the parts during the comparatively short time during which said toe parts are inserted into the steamer.
Of course, the soap itself does not serve.
any particular purpose as a protecting sub stance, but it enables the Wax to be held in suspension to provide a compound in a suiriciently fluid form to be applied by abrush. Having describedmy invention, I claim: 1. Thatimprovement in the art of making ass? shoes which consists in applying a coa-tr of heat-resisting material to portions or shoe adjacent to other portions which are to be softened, then subjecting said portions to the influence of a softening agent.
2. That improvement in the art of making shoes which consists in applyinga coating oi heat-resisting material to some portions of the shoe before completion of the lasting operation, then subjecting said portions to the action of steam, and then completing the lasting of the shoe.
3. That improvement in the art oi making shoes which consists in applying a coat ing of heat-andmoisture resisting material to the toe portion of the insole before completion of the lasting operation, then subjecting the toe portion of the shoe to the action of steam, and then completing the lasting of the shoe.
4. That improvement in the art of making shoes whichconsists in covering toe portions of the shoe with a coating of moisture ancb heat resisting-material, then subjecting said toe to a moistening and softening process, and then lasting the toe 01"" the upper.
5. The method of protecting shoe uppers against damage from moisture or heat during a softening operation, consisting in covering said parts with a coating of moistureand-heat-resisting material and subjecting the parts to the influence of moistheat.
In testimony whereof I have signed my name to this specification.
