DIVISION No. 2.

` To all whomt may concern Be it known that JOHN M. VIMLEY, of

' the city and county of Philadelphia, and State of Pennsylvania, did invent a new and useful method or Inode of constructing or making composition soles, and of attaching the same hereby declare that the following `is a full, clear, and exact description thereof, reference being had to the accompanying drawings, a-nd to the letters of reference marked thereon.

Soles of boots and shoes were heretofore most generally made of leather, this material being peculiarly adapted to this purpose, because of its durability and the facility with which they may be secured to the uppers by sewing, pegging, nailing, or other mechanical means but leather soles, besides being more or less pervious to water, are costly, both on account of their material and the labor involved in cutting, fitting, trimming, and other Operations attending their construction and attachment tothe uppers. Attempts at producing a cheaper and in some respects a better article as a substitute for leather soles resulted in the production ot' com position soles-416., soles made or formed in molds of some plastic material which, after being molded undergoes a change, whereby it becomes hard, tough, iiexible, or elastic,im pervious to water, and more or less resisting to tear and wear. The great difeulty experienced in the employment and introduction of these composition soles consisted iu attaching them to boots and shoes. Numerous experiments tried to attach them by means of pegs, nails, rivets, or other mechanical means failed, because, unlike leather, whose texture is interwoven and continuousthe composition sole, which is composed of small particles agglomerated or cemented together, cannot be pierced, cut, or trimmed without at the same time destroying its durability and imperviousness. Uementiug substances have therefore been resorted to to fasten composition soles to boots or shoes 5 but while soles so fastened become easily detached under the influence of changes in the weather, they require in most cases an intermediate sole, (attached to the uppers by mechanical means,) to which they may be cemented.

From this statement ot' the condition of the art previous to the date of this invention the object and value of this invention will be more fully understood.

The invention subject of this patent relates to the manufacture ot composition soles and to the mode of attaching the same to boots and shoes, the object being to produce a com posit-ion sole which may be attached by mechanical means to boots and shoes without involving the necessity of piercing, cutting, or trimming the same, and so as to preserve its durability and imperviousness; and this invention consistsin combining a composition sole with staples or other metallic clinching devices When the latter are partly embedded in or incorporated with the former, substantially as hereinafter set forth.

To enable others skilled in the art to make and use thisinvention, I shall now proceed to describe, in illustration thereof, the manner in which thesame is or may be carried into effect, premising, however, that this invention is susceptible of many modifications without departure from the principle thereof, and that the example here given relates to the making and attaching of composition soles which are more particularly applicable to heavy boots and shoes.

Referring to the drawings, Figure 1 is a perspective view of a cast-iron mold in which the sole is formed; Fig. 2, a like view of a shoe as prepared upon the last for the reception of the sole; Fig. 3, a like view of the shoe upon the mold; Fig. 4, a like view ot'a cast-iron heel which may be applied when required, and Fig. 5, a sectional side view of one of the iron staples inserted through the upper and insole for securing the outer sole to the boot or shoe, like letters indicating the same parts in the ditferent figures.

The mold A is made of cast-iron, and of such form as to produce a sole, as hereinafter described, and is divided longitudinally into two parts, which are hinged together at the heel, and so as to be readily opened and elosed'as occasion may require. The shoe or boot is lasted in the usual manner, the upper B being held down upon the insole C by means of temporary tacks in the usual manner pre p erch a.

paratory to the insertion Vof the staples D D, by means of which the composition sole is permanently secured thereto. The staples D x are formed of wire, the two ends being bent down at right'angles and driven through the upper and insole, as shown in Fig. 2, so as to clinch on the inner side of the insole, as shown i in Fig. 5, by coming in contact with the last, i which at this part must be made or covered with metal. In order to cause the ends of the sta'- ples to clinch more readily, I usually reduce i jections thereon, adheres firmly tothe compoy them to ajiat edge with the hammer before drivin gthem into the leather. In theoperation i of driving the staples l use a flat piece of hardl wood or metal, which is about a sixteenth of y an inch thick and about half au inch Wide. l, After the staple is entered I place this tool l between it and the upper, and then -drive the staple down upon it, so that the ends ot' the i staple become clinched or bent up against the inner side of the insole by the resisting last, l

and, the tool being thenwithdrawmthere is necessarily a space left between the upper and the staple. The staples D D being thus inl serted around near the outer edge of the boot vor shoe, as shown in Fig. 2, it is ready for receiving the composition sole. I make the comi position for this purpose chiefly of gutta-l The boot or shoe being ready for the cuter sole, as before described, I put enough of the composition to form the said sole into Warm Water, which prevents its sticking to ,the l hands in forming and molding. I now form it into near the required shape with the hands, and, if a very hard and durable sole is l required, I also insert numerous metal plugs or short stub-nails into the under side. I then place it in the mold A, and immediately press rt-he boot orishoe down upon it and hold the latter thus for a feW minutes, When, the coml position having become hard or' set,7 the mold may be opened and the boot or shoe taken l out. 'The-s0le, heilig thus perfectly formed, l

is permanentlyv held also to the same by means of the staples D D. I now blackerr and varnish it in the usual manner, and it is ready for use.

it of malleable cast-iron inthe form shown in Fig. 4, and place it in the mold before putting therein the composition.

rough on the inner side, or having small prosition, and thus `\an exceedingly durable. and substantial heavy heel is produced. In lighter boots and shoes I make the heels Wholly of the composition, and also dispense with the metal plugs in the bottoms of the soles. times use dat-headed nail-s instead of the staples D D for the purpose of holding Ion the soles', but I prefer rthe staples.

It will be evident that shoes or boots having scles'ot' composition and attached in the therefore cheaply, as the cost of the material Y does not exceed that of sole-leather.

Having thus fullyset forth the nature of this invention and the manner in which the same is or may be carriedinto effect, What is.

claimed as the invention of the said JOHN M. WIMLEY is The combination of a composition sole with staples or other metallic clinching devices, when the latter are partly embedded in or incorporated with the former, substantially as set forth. Y

In testimony whereof I have signed my name to this'specication before two subscribing witnesses.
