LOGAN MCFARMNE, OF HALTON, NEAR LEEDS, ENGLAND.
MANUFACTURE OF MOLDED ARTICLES, MORE PARTICULARLY HEELS AND SOLES FOR FOOTWEAR.
No Drawing.
To all whom it may concern: I
Be it known that I, LOGAN MoFAnnAnE, a subject of the King of England, residing at Halton, near Leeds, England, have 1nvented certain new and useful Improvements in the Manufacture of Molded Artic es, More Particularly Heels and Soles for Footwear (for which I have filed application in Great Britain, 28th November, 1021, Patent No. 197,980), of which the following is a specification.
The present application relates to the manufacture of articles more particularly heels and soles for foot-wear from a cellulose fibrous composition by moulding, pressing and drying.
The invention consists in an improved method of rendering the cellulose fibrous composition more or less waterproof after compression in the mould, which consists in adding to the wet disintegrated cellulose fibre asizing and binding composition, for instance resinate of soda, precipitating the sizing by the addition of a precipitant, for instance sulphate of alumina, heating the cellulose fibrous mixture to about 180 F., putting same into a hot mould and subjecting to pressure.
'The cellulose fibre may be wood pulp produced by well known processes and the cellulose fibrous composition is prepared in the following manner To say 100 pounds air dry disintegrated wood pulp is added et00 gallons of water. To this is added 20 pounds of a sizing and. binding composition which is prepared by mixing one part of Scotch glue to three parts of'resinate of soda and heated to 180 F. The sizing and binding composition is diluted with hot water to the consistency of milk before adding to the pulp and water and thoroughly incorporated with it by suitable stirring apparatus. The whole is subjected to heat in a suitable jacketed container, up to 180 F. or more. Sufficient sulphate of zinc is then added to precipitate the resin and glue. A small quantity of tannic acid may be added to react on and toughen the glue. To accelerate the binding or setting of the article in the mould a small'quantity of formaldehyde is added immediately before the mixture is passed into the mould, which is heated to 212 'F. and submitted to pressure. is cooled under pressure, say to 160 F., by suitable means. The excess moisture is The molded article Application filed October 11, 1923. Serial No. 668,005.
expressed through suitable drain holes in. the mould. d
The resulting product of this process is tough, light and waterproof. Instead of the glue and resinate of soda composition for sizing and binding, casein, gelatine, albumen, resinate of soda or other well known sizing agents may be used in conjunction with well known prccipitants such as sulphate of alumina or chloride of zinc.
It may be pointed out that the essential features of the invention are using heat throughout the process, and entirely dispensing with silicious filling.
I claim 1. In the manufacture of articles, more particularly heels and soles for footwear from a cellulose fibrous composition by moulding, pressing and drying, a method of rendering the cellulose fibrous composition more or less waterproof after compression in the mould, consisting in adding to the Wet disintegrated cellulose fibre a sizing and binding composition comprising resinate of soda and an adhesive material of animal origin, precipitating the sizing by the addition of a precipitant, heating the cellulose fibrous mixture to about 180 F., putting same into a hot mould and subjecting to pressure, substantially as described.
2. In the manfact-ure of articles, more particularly heels and soles for footwear from a cellulose fibrous composition by moulding, pressing and! drying, a method consisting in adding to the wet disintegrated cellulose fibre, resinate of soda and glue, preferably in the proportion of one part of glue to three parts of resinate of soda, adding a. precipitaut. preferably sulphate of zinc, preferably also adding a small quantity of tannic acid, heating the fibrous mixture to about 180 F. and submitting to pressure in a hot mould and cooling under pressure, substantially as described.
3. A method according toclaim 2, further characterized by the fact that a. small quantity of formaldehyde is added to the cellulose fibrous mixture immediately before passing it into the mould, substantially as described.
In testimony whereof I have here-unto set my hand in the presence of two witnesses.
LOGAN MoFARLANE.
