Definitions

• My invention is designed to overcome this difiiculty by providing a felt for cushions, upholstery, mattresses and the like which will indefinitely retain its soft and elastic quality and which will not become hard and compact in use.
• the softer fibers are capable of being felted sufficiently to give the required Specification of Letters Patent.
• the stiffer and more springy fibers resist felting and tend to remain in the mass in their original condition. Their inherent tendency to spring back to their original position when disturbed causes them to act as numerous springs disseminated through the mass to keep it in a loose and soft condition.
• the stiffer and more spr ngy fibers act in opposition and by their springlness prevent compacting and hardening of the felt.
• Hog bristles have been found to be of suitable length, weight, resiliency and rigidity to answer the purpose of the stiffer and more springy fibers, but vegetable fibers such as Tampico may be used if desired.
• a felt of the sort here described may be manufactured of any desired thickness and may be cut to required sizes for the manufacture of cushions or mattresses of given dimensions, or for the upholstering of seats of definite size, as in automobiles.
• a felt consisting of a mixture of at least two kinds of fibers, the fibers of at least one kind being capable of felting sufficiently to produce a self-sustaining body and the fibers of the other kind being of a stiffer and more springy character than the first and of sufficient length and resiliency to prevent compacting and hardening of the fibrous mass, whereby the felt maintains a springy and soft character in use.
• An article of manufacture consisting of a mixture of cattle hair and hog bristles, the latter serving to prevent compacting of the cattle hair when the latter is subjected to pressure in usage.
• Felt consisting of 757, more or less of cattle hair and 25% more or less of hog bristles.
