J. JENKINS, OF CHARLESTOVVN, MASSACHUSETTS.
HEATING APPARATUS FOR THE MANUFACTURE OF CEMENTED-SOLE SHOES.
Specification of Letters Patent No. 21,500, dated September 14, 1858.
To all whom it muy concern;
Be it known that l, JACOB JENKIXS, of Charlestown, in the county of Middlesex and State of Massachusetts, have invented an Improved Heating Apparatus for the Ise of )Workmen in Applying Cemented Soles to Boots and Shoes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a. side elevation. Fig. 2 is a plan; Fig. 3, a transverse vertical section on the line :c a; of Fig. 2; Fig. 4L, detail to be referred to hereafter.
In the manufacture of those boots and shoes the soles of which are cemented to the uppers, and one sole to another, by a coating of gutta percha applied to the sole, it has heretofore been customary after the boot orshoe was lasted to place it in an oven or stove raised to a. suicient temperature to soften the coating of gutta percha applied to the inner sole, and then to apply the outer sole also similarly coated and heated, when by the application of pressure the two soles were made to adhere firmly together. It is found however that the heat required to soften the cement is injurious to the stock of which the upper is composed.
To remedy this is the object of my present invention which consists in the employment of a simple heating apparatus so arranged that the required heat may be applied to the surface of the inner sole after the boot or shoe is lasted without injury to the upper.
That others skilled in the art may understand and use my invention I will proceed to describe the manner in which I have carried out the same.
In the drawings A is a box lined with tin as at a, Fig. 3. In one end is placed a door B, and in one side a pane of glass 79, is inserted, that the workman may have the benefit of the light from the lamp C, which is used for heating. The lid D of the box is made removable and rests on the ends of the box and on the tin lining, which. is bent over as at 1 2, Fig. 3, all the way around the top of it to cover the point. This lid is covered with stout cloth or felt as at c, Fig. 3, and has cut in it two holes `of a size and form coresponding to the boots or shoes to j be made as shown dotted in Fig. 2 and at (l,
Fig. 3. The surface of the lid is also slightly undulating as dotted at e, Fig. l, to conform more closely to the forni of the edge of the sole. A number of these lids' may be kept on hand with different sized holes.) Then these holes or either of them is not occupied by a boot or shoe to be heated, it is covered with a block E, Figs. 2 and 3, made to fit closely over it, which retains the heat in the box. A metal deiiector f rests on two rods f/ which extend across the inside of the box near each end. This is placed over the lamp C, to prevent the iame from striking with too much intensity yon one part of the sole. It may be moved along on the rods from one side to the other.
A strip of metal /lzy having suitable notches in it is attached at one end to the lining a and is supported by a piece i rising from the bottom of the box. Another strip 7s is attached to the side lining and has in it a series of holes corresponding to the notches in the strip 71.. Small rods Z, are placed with one end in the holes in the strip k. and rest in. the notches in the strip lz., thus forming a rack which is readily removable and which serves as a convenient place to lay the stock to be warmed (as the outer sole for instance). The lamp may be moved to any part of the box as required.
F. represents the last with the upper fm,
on it and the inner sole n (Fig. 3) attached. After the inner sole has received a coating of gutta percha the shoe is placed over one of the holes in the lid, as shown in Fig. 3, to be heated. At the same time the outer sole, Fig. 4. which has also been coated, may be placed on the rods Z and be heated at the same time, ready for the operator to put them together and finish the shoe. It will be perceived that the edge 5. of the upper tits closely to the cloth c around the hole (Z and prevents the heat from the lamp injuring the stock in the upper while the bottom of the sole is exposed to the required temperature.
This will be found to be an exceedingly convenient apparatus for the workman engaged in this branch of manufacture and will enable him to economize, as the lamp or gas light required for him to work by in the evening` will also serve to heat his stock` while it prevents his injuring the uppers by subjecting them to too great a heat as he Was liable to do Where the Whole shoe was placed in a heating apparatus.
I have sometimes found it convenient when heating the outer sole, Fig. et, to place it with the cemented side down on one of the holes cl. This allows the cement to be properly heated Without drying and contracting the sole, as Will be the case when put into the heater.
I have heretofore spoken of applying the necessary heat to the soles of shoes by means of a lamp or gas light, but it is evident that other methods of producing the required heat may be used Without departing from the spirit of my invention, as for instance steam, hot air, or hot Water may be led sisting of the box A, provided With door B,- glass front b, delector f as described, open-- ings d, and VlampC, or its Yequivalent for heating, arranged and operating substantially as and for the purpose above set forth.
