stop1 (stop)

[ mutation-stops sounding an octave below the normal pitch of the s are called sixteen - feet stops; those sounding the octave above, four-feet stops; those sounding the second octave above, two - feet stops, etc. The specific names of stops are not only numerous, but often vary without sufficient reason. Some names have a merely technical significance, as diapason, principal, etc.; some indicate the instrument which they are intended to imitate, as flute, trumpet, violoncello, etc.; while others mark the extent of the mutation produced, as octave, twelfth, quint, etc. Each partial organ has its own stops, which can be sounded only by means of the s of its own keyboard. The pipes of a stop are usually arranged in a transverse row on the wind-chest, the order of disposition, or plantation, varying somewhat. Under them, and between the upper and middle boards of the chest, is a movable strip of wood called a slider, which (together with both these boards) is perforated with holes corresponding to the plantation of the pipes. The position of the slider is controlled through a system of levers by a handle near the keyboard called a register, stop- knob, or stop. When this handle is pulled out or drawn, the holes of the slider are coincident with those of the two boards, so that the air can pa freely from the pallets into the pipes; when the handle is pushed in, the holes of the slider are not coincident with those of the two boards, and communication between the pallets and the pipes is cut off. In the one case the stop is said to be "on," in the other "off." When the slider controlling the use of the upper pipes of a stop is separated from that controlling the lower, the stop is called divided. Since the handles controlling the use of the pipes or stops proper are made of the same general shape as those controlling various mechanical appliances, like couplers, the former are also called sounding or speak ing stops, in distinction from the latter, or mechanical stops. Stops whose quality or power of tone is decidedly individual, so as to fit them for the performance of solo melodies, are called solo stops. See organ, reed-organ, pipe, etc. alter the force or quality of the tones produced. -9. A mark to indicate a stop or pause in reading; a mark of punctuation. I can write fast and fair. Most true orthography, and observe my stops . Middle ton, More Di emblers besides Women, iii. 2. Who walked so slowly, talked in such a hurry, And with such wild contempt for stops and Lindley Mur- ray! C. S. Calverley, Isabel. 10. In joinery , one of the pieces of wood nailed on the frame of a door to form the rece or rebate into which the door shuts.-11. Naut .: (a) A projection at the head of a lower mast, supporting the trestletrees. (b) A bit of small line used to lash or fasten anything temporarily: as, hammock- stops , awning- stops . -12. In op- tics , a perforated diaphragm inserted between the two combinations of a double lens, or placed in front of a single lens, to intercept the ex- treme rays that disturb the perfection of the image. The practical effect of the stop is to increase the depth of the focus and sharpne of definition, but to diminish the illumination in the exact ratio of the diame- ter of the stop to that of the lens, and hence, in photogra- phy, to increase correspondingly the nece ary time of ex- posure. Microscopes, in which, whatever be the size of the lens itself, the greater portion of its surface is rendered inoperative by a stop. W. B. Carpenter, Micros., § 10. 13. In bookbinding, a small circular finishing tool used by bookbinders to stop a line or fillet at its intersection with another line. - 14. In lace - manuf. (in the application of the Jacquard attachment described under loom, 2, to a lace frame), a point at which the different sets of warp-threads are concentrated or brought to a sort of focus, and which in the design of a pattern is taken as a basis for measurement in determining the distances the respective threads in the set must be moved to form the desired pattern. The movements of the mechanism are adjusted in accordance with these measurements.-15. In phonetics, an alphabetic sound involving a complete closure of the mouth-organs; a mute; a check. - 16. The concavity of the profile of a dog's face, specially marked in the bulldog and pug.-17. In fencing, the action whereby a fencer, instead of parrying a blow and then thrusting, allows a carele opponent to run on his sword-point. He may hasten the stop by extending the sword-arm. (See stop - thrust.) The stop is discouraged in fencing as a game, since much use of it shortens the pa ages, and destroys combinations of feints, disengagements, coupés, etc. - Double stop. See single stop. - Full stop. (a) A period. (b) In lute playing: (1) A chord followed by a pause. (2) A chord in producing which all the strings are stopped by the fingers. Geneva stop.

See incomplete. - Open stop, in organ - building, a stop whose pipes are open at the upper end. - Pedal stop. See pedal. -Service stop, in railroading, a stop made by a railway train, in the regular way and at stations designated by the regulation schedule, as distinguished from an emergency stop. Single stop, in ship - building, the scoring down of the carlines between the beams, by which means a carline is prevented from sinking any lower than its intended position. The double stop is generally used for deeper carlines than the single stop. To hunt upon the stopt, to hunt with or like a stop-hound-that is, slowly and with frequent pauses; hence, to be lukewarm.
