Silv′er-ing-ma-chine′
（
Wood-working.) A machine for cutting splints, slivers, or shreds of wood for various purposes.
a. Narrow thin slats for making woven windowblinds in which slats form the weft.
Slats or scaleboard of thin wood, capable of being worked up into boxes for millinery, collars, small fruit, and what not.
Splints for making up into baskets.
Free's machine for cutting slats for blinds has a knife set in a reciprocating stock, which moves below the block to be worked; the knife-carriage on its return strikes a lever connected to a pawl that operates gear-wheels to feed down the block of wood for the next cut. See slat-making machine.

b. Finely shredded wood to serve as a substitute for curled hair for upholstery purposes.
Known as
excelsior.
Machines for slivering wood into small shreds, called
excelsior, usually make two cuts; one to sever a scale, and the other to split the scale into shreds.
Taggart's machine, January 23, 1866, has a rotary annular plane with a series of plane-bits and scoring-cutters thereon, and above which is a cylinder having a series of block-holders, so arranged that the blocks will fall on the annular plane after the action of each plane-bit and scorer, so that the whole block will be cut and scored into fine fibers.
Brooks and
Clements' excelsior machine, March 25, 1868, is also a rotary shredder.
The bolt is pressed downward within its fixed case by a weighted lever, and subjected to the action of the scoring and plane cutters at the upper surface of the horizontal rotating wheel.
