Description
FREDERICK n. 'wooDwABD, or LACHINE, QUEBEC, CANADA.
SHOE-FILLER.
N 0 Drawing.
T all whom it may concern:
Be it known that I, FREDERICK E. Wooo- WARD, a citizen of the United States of America, and residing at No. 577 St. Joseph street, Lachine, Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Shoe-Fillers, of which the following is a specification.
The invention to be hereinafter described relates to shoe fillers.
The main objects of the invention are to provide a commerciable, marketable, transportable filler which will be economical in its production and use and will have the following qualities; permanent pliability, durability, waterproofness, elasticity, resiliency, softness and workability, strongly adherent to leather whether wet or dry, tenacious, low melting, quick cooling, rapid setting and stable or non shifting.
At present there are two classes of fillers on the marketrubber cement fillers, and ground cork fillers. Neither of these adequately meets the demands. The first is dangerous from fire and is wasteful and expensive because of evaporation, while the second requires a long time to set, involving long and expensive delays in the other step of manufacture.
To fully and adequately meet all of the requirements herein-before enumerated the present filler has been invented. It comprises the ingredients hereinafter stated, and mixed substantially in the manner and proportions set forth in the following description. Preferably, what will be hereinafter termed the compound, is first made. This compound, which also performs the function of a binder, is then mixed with a base of ground or granulated cork, sawdust, leather dust, or any suitable substance of like nature.
The preparation of the above filler is as follows: 450 lbs. of Burgundy pitch and 1 lb. of asphalt are put together in a steam jacketed kettle or other suitable vessel and heated until they become fluid. Into this hot fluid mass is then thoroughly stirred lbs. of red engine oil. The oil and asphalt act upon the pitch to render the resulting mass soft, semi-plastic, flexible, resilient, elastic, non-brittle, pliable, waterproof, stable, tough, tenacious, adhesive, readily workable, low melting, quick cooling, and rapid setting. The pitch alone,upon cooling would 7 become hard and brittle, of"
specification of Letters Patent.

course. Into this hot compound is stirred the ground or granulated cork, saw-dust,
before the oil is added. This increases the working qualities of the filler so that it will smooth ofi? better and give a more finished and neater appearance when molded into the cavity of the shoe sole. Also, before mixing in the oil of the compound, 10 lbs. of bicarbonate of soda should be added and thoroughly dissolved. The bicarbonate of soda makes the resulting filler substantially non-inflammable. The heated compound and consequently, the filler containing it, gives off a non-inflammable gas, thus substantially preventing combustion of the filler. Thus, in addition to the qualities previously enumerated, this filler has the additional qualities of non-inflammableness and smoothness and evenness in working when being molded into the cavity.
The ingredients above named are common trade articles and, therefore, vary more or less inpurity. Consequently, their proportions will vary somewhat, on that account. Likewise, the requirements of the filler for use in summer are different than the requirements for winter. For that reason, the pro portions will be varied. Thus, for winter use, for instance, there would be a greater quantity of oil than for summer use. Obviously, other ingredients having either individually or collectively, similar properties may be used for those specifically mentioned. Many of these are well known on the market and would readily occur to any one skilled in the art to which this invention relates.
Therefore, they need not be set forth here. Having fully set forth and described my invention, what I claim and desire to protect by Letters Patent of the United States is 1. A shoe filler comprising Burgundy pitch, oil, a comminuted resilient solid ma-.
.terial, and an ingredient. which, when combined with said ingredients and heated gives off an incombustible gas.
2. A shoe filler comprising Burgundy oil mixture, asphalt, and bi-carbonate of pitch, oil, a comminuted resilient solid masoda. terial, and bi-carbonate of soda. f 5. A shoe filler comprising Burgundy 3. A shoe filler comprising Burgundy pitch 450 lbs., oil 60 lbs., a comminuted re- 15 5 pitch 450 lbs., oil 60 lbs., and a comminuted silient solid material in the proportion of 25 resilient solid material in the proportion of lbs., to 6 gals. of the pitch and oil mixture, 25 lbs. to 6 gals. of pitch and oil mixture. and bi-carbonate of soda.
4. A shoe filler comprising Burgundy FREDERICK E. WOODWARD. pitch 450 lbs., oil 60 lbs., a comminuted Witnesses: l resilient solid material in the proportion GEORGE H. Cross,
of 25 lbs. to 6 gals. of the pitch and RICHARD E. WOODWARD.
