LEFT JOINT STOCK 274 JOINVILLE tures different from both. The different kinds of joints may be thus classified: 1. Synarthrosis: (1) Suture, (2) Schin- dylesis, (3) Gomphosis, (4) Amphiar- throsis. 2. Diarthrosis: (1) Arthro- dia, (2) Enarthrosis, (3) Ginglymus, and (4) Diarthrosis rotatorius. Th^ terms symphysis, synchondrosis, syneuro- sis, syssarcosis, and meningosis, former- ly applied to joints, are now discarded. In carpentry, a mode of securing to- gether the meeting edges of wooden structures; the place where one piece of timber is united to another. The straight joint is where the edges make a butt- joint, being planed straight. Timbers are generally joined by mortises and ten- ons, or by straps and bolts. The various kinds of joints are named according to their forms and uses, thus: (1) A but- ting joint, in carpentry, is one in which the fibers of one piece are perpendicular to those of the other; in machinery, one in which the pieces meet at right angles. (2) A bevel joint, one in which the plane of the joint is parallel to the fibers of one piece and oblique to those of the other. (3) Dove-tail joint. (4) A longi- tudinal joint is one in which the common 5?eam runs parallel with the fibers of both. (5) A miter joint, one formed by the meeting of matching pieces in a frame, the parts uniting on a line bisect- ing the angle, which is usually, but not necessarily, one of 90°. (6) A square joint, one in which the plane of the joint is at right angles to the fibers of one piece, and parallel to those of the other. In geology, a natural fissure or line of parting traversing rocks in a straight and well-determined line, often at right angles to the planes of stratification. In masonry, the face- joints of vous- soirs are those which appear on the face of the arch. The vertical joint is be- tween stones of the same course. The horizontal joint is between courses. The coursing-joint is the joint between the courses of voussoirs. The heading- joint is that between two voussoirs in the same course. The flush-joint is filled up to the face by pointing with mortar. In plumbingj the sheets of sheet-metal roofing are joined by a drip- joint or a flashing-joint in cases where they are not soldered. A flush-joint or jump-joint is a butt joint covered with a plate on the inner side, called the butt plate. In a lap-joint the pieces overlap each other. The word is also applied in slang to an opium-smoking den; or any resort of bad repute. JOINT STOCK, stock held jointly, or in company. A joint stock company is a kind of partnership entered into by a number of individuals for the purpose of carrying on some trade or business with a view to individual profit; invested by statutes, in Europe and many of the United States, with some of the privi- leges of _ a corporation. In ordinary partnerships, the members contribute more or less of their own personal labor or management to the affairs of the com- pany. In joint stock partnerships, on the other hand, the members only con- tribute to the funds or "stock" of the company, without having any direct share in the management; and hence their name. The capital of the company is generally divided into equal parts, called "shares," a certain number of which are held by each member of the company; and in proportion to the num- ber of these he is entitled to participate in the profits of the undertaking. These shares are freely transferable without the consent of the company. JOINVILLE (zhwawfi'-vel'), a small town of 4,000 inhabitants in the French department of Haute-Mame, which was formed into a principality by Henry II., and later supplied the title to the 3d son of Louis Philippe.
