contain the ground coffee through which the boiling water is poured. The wire strainer is a substitute for the flannel bag. Cof′feeclean′ing ma-chine′. A machine resembling a bran-duster or smut machine, in which the coffee grains are beaten, rubbed, brushed, and winnowed to remove the parchment, or thin adhering envelope of the grain, and also purge it of dust and foreign matter. The devices are numerous, but generally consist of rotating beaters, rubbing surfaces, fans, etc. Newell's patents, 1857 and 1859, may be taken as a type. A steam-heated cylinder, wire-ganze cylindrical envelope, rotating beaters. Following these are about sixteen patents. The object of some is to clean the grain; of others to produce a yellow, brown, or golden color, to increase the commercial value. Sand and talc-dust are used by some to rasp the grain. Coffee-huller. Cof′fee-hull′er. A machine to remove the husk or sac which covers the coffee-grains. It consists of an

an outgrowth of the keygrooving machine. Key-guard. A shield which shuts down over a lock-key to prevent its being pushed out of the lock from the outside. In the example, a slotted escutcheon on the plate shuts over a flattened portion of the key-shank to prevent its being turned by an outsider. A pawl acts as a detent for the escutcheon. Key′hole-pro-tect′or. Mitchell and Lawton's English patent, 1815, has a revolving curtain for closing the keyhole. Key-guard. Day and Newell's parautoptic lock has a revolving ring or curtain, which moves with the key and shuts the hole, so that wires and tools cannot be introduced alongside the key. Mordan's keyhole protector (English), 1830, has a short pipe which, after the door has been locked, is thrust into the keyhole; attached to the pipe is a small lock so contrived that, on turning its key, two lancet-shaped pieces fly out laterally and bury themselves in the wood. The escutcheon cannot be removed until the small ke

of course cannot be replaced. See seal-lock. Chubb's lock, 1818, has six or more tumblers turning on a pin common to all. Each of these must be lifted to a different hight before a stud on the bolt can pass through a continuous aperture formed by a slot in each tumbler when all are in their proper position. Should either of the tumblers be overlifted by the introduction of a false key, it is held in that position by a spring, thus indicating that the lock has been tampered with. In Newell's American lock (exhibited in England in 1851) the bits are interchangeable on the stem of the key, so that an indefinite number of combinations may be formed, each of which so alters the relative position of the tumblers at the moment of locking that they can only be brought into position to allow the bolt to be withdrawn by the same arrangement of the bits. There are three sets of bits, the two nearest the keyhole falling to a common level when the key is withdrawn, while those of the th

The letter-lock (which see) appears to have been the earliest of this class; and locks on the same principle, but of more complicated mechanism, still form a favorite subject of invention. The permutation principle was introduced into tumbler-locks by Dr. Andrews of New Jersey, about 1841. The tumblers are capable of variable adjustment, and the key has a series of small shiftable steel rings of such radii as to suit the variable tumblers. To this succeeded the Hobbs lock, invented by Newell of New York, which is provided with a series of secondary tumblers separated from the main tumblers by a wall; the secondary tumblers have notches corresponding to teeth on a series of intermediate tumblers, which teeth correspond to the hights of the main tumblers; in shooting or retracting the bolt the intermediate tumblers are engaged with both the primary and secondary tumblers, lifting the latter to the hight determined by the variable arrangement of the movable key-bits, but when the b
