Prime Movers and Their Accessories. STARTING DEVICE FOR INTERNAL COMBUSTION ENGINES.—R. O. Le Baron, Masonic Temple, Portsmouth, Ohio. The object here is to provide means which may be used at will to connect an acetylene gas tank with the intake of the engine, so that the gas will mix with the explosive mixture and flow into the engine cylinder, which with a proper spark mechanism, will insure an explosion in the engine cylinder on the first, or in any case on the second, rotation of the engine shaft. MEANS FOR COOLING INTERNAL COMBUSTION ENGINES.—R. F. E. Okrassa, Antigua, Guatemala. In the present patent the object of the invention is the provision of a new and an improved means for cooling internal combustion engines, in a very simple and economical manner, and for this particular purpose use is made of moistened air moved in contact with the cylinder of the engine. Railways and Tlieir Accessories. RAIL .TOINT.—F. C. Botwrigiit, Philadelphia, Pa. This invention has reference more particularly to a rail joint which comprises a base having rail-engaging means, a chair mov-ably mounted upon the base and adapted to support the rail ends, means for causing the relative lateral movement of the base and the chair to secure the rail ends in position, and means for holding the rail ends. METALLIC TIE AND RAIL FASTENING DEVICE.—Joel F. Robinson, Central, S. C. This device eliminates the use of spikes, which split the tie, work loose, and otherwise destroy its life and causing many wrecks. The rail attachment is as well adapted to the wood tie as to the metallic one. It is made on a sheet iron or metal plate covering the end of the wooden tie, thereby extending the life and usefulness of a worn out tie and giving safety against spreading rails. The tie is automatically attached to the rail by an eliptic locking device, which holds the rail immovably, guarantees an exact gage of track \ and releasable only by the use of a wrench. The locking device is underneath the rail and inaccessible to train wreckers. It is not liable to be disturbed by any cause until a wrench is used. The form of tie is especially adapted to elevated service and on ballast roadbeds. The invention provides for insula-1 tion, and the engraving shows a top plan view. CAR TRUCK.—C. A. Lincoln, Wayne, Maine. The object here is to provide trucks for rail-\ road cars, constructed and arranged to dispose the axles of the wheels in a radial position upon the curved sections of the track in order to eliminate friction at these curves. A further object is to so arrange the trucks that any obstruction upon the track would not tend to •cause the wheels to leave the roadbed. DOOR FOR GRAIN CARS.—J. W. Wheeler, Palmyra, Neb. This invention relates to a door for grain cars, coal cars and the like. One object of the improvement is to provide a door which can be rigidly and securely fastened to the framework when in use. and may readily be swung out of the way when not in use, and further provides means for attaching the door to the framework on the car in both of these positions. WATER-GAGE.—J. A. Cooper, Jersey City, and W. R. Van Buskirk, Paterson, N. J. This invention provides a water-gage for determining the level in boilers especially on locomotives. The gage is strong and durable, and Is not liable to blow out. and even if it should blow out, the fragments of glass would be caught by a protector, preventing them from flying and injuring the person or eyes of the engineer. DOOR HANGER FOR CAR DOORS.—J. T. Grimshaw and L. R. Wellington, Rialto, Cal. An object in this instance is to provide a hanger which will permit the car door to be easily opened and closed and which will render the binding of the door impossible. A further object is to provide a device having a novel form of adjustment for 'the easy 'opening and closing of the door, together with means for preventing wear of the attachments. Pertaining to Recreation. SWING.—G. D. Tucker, Meridian, Miss.

GAME APPARATUS.—J. E. YOST, care Yost Yeast Co., Arkansas City, Kan. An object of this invention is the provision of a new and improved game apparatus for playing a game of checkers on a map by the use of traffic routes or lines to move on, the towns along the routes as points to move to, and towns at the end of the map as “king row.” The game is highly interesting and educates in geography. Pertaining to Vehicles. PNEUMATIC WHEEL.—S. P. Cox, Bayport. N. Y. This inventor provides an improved construction of wheel, in which the tire is made up of separate units, each carrying its own pneumatic cushion, and its individual foot (or feet) associated with the cushion, the various units being removable at will and consequently interchangeable. BRAKE LOCK.—W. S. Bristol, Anthony, Kan. To accomplish the purposes of this invention use is made of a brake lever for connection with a brake shoe, a locking rod mounted on the brake lever, a locking lever adapted to be engaged by the locking rod to. lock the brake lever relatively to the locking lever and means for limiting the movement of the locking lever. VEHICLE WHEEL.--. C. Thoen, Burke, Idaho. The aim in this case is to provide a novel construction of spring wheel which will have sufficient resilience to permit its practical operation on automobiles and the like without pneumatic tires. An important feature of the invention is the coiled portions of the spokes which give greater resiliency to the spokes and thus improve the action of the wheel. GEARING.—Howard G. Carr, 910 E. Main St., Hoopeston, 111. This invention is shown in the enlarged plan view of the chassis of a motor vehicle, exhibiting the engine for driving the vehicle, and in cross section, the gearing connecting the engine and the driving axle. The object is to provide a motor vehicle in which the engine is mounted adjacent to the driving axle and is operatively connected there- with by means of efficient and compact, variable speed gearing, which permits the vehicle to be driven at different speeds and in different directions, which dispenses with a shaft or chains for operatively connecting the engine shaft and driving axle, and in which the mechanisu is so arranged that it can be easily assembled and taken' apart and is accessible , without difficulty for repair or other reasons. TACHOMETER.—Max Hoeft, Berlin, Germany. (Peterson&Schulz, agents.) The engraving herewith shows front elevation of entire apparatus after removing the front plate of clockwork and the front end disk of the paper roll and showing the casing in section. 'The actual printing motion, for example the pressing of the type against the paper on which, the record is to be made, is not carried out by a clockwork spring or weight adapted to be wound up periodically, but either by coupling the printing mechanism with a shaft, or some other part, driven by the motor or by force of the person moving some operative part of the vehicle or motor. Printing is thus effected with the greatest certainty and the apparatus can not fail owing to insufficient force being available as can occur when a clockwork spring is used. The complicated mechanism heretofore necessary in order to automatically wind up a clockwork spring is now avoided. DOOR SIGNAL.—L. L. Bories, San Francisco, Cal. ''he object of the present invention is mainly to provide an automatically-acting indicator device actuated by the closing of the door. This device is particularly adapted for use on automobiles and other vehicles, and at all times to see that the door is opened or closed without turning his head. SLEIGHING ATTACHMENT FOR CARRIAGES.—J. P. McCready, Berlin, N. II. This attachment is for use for baby carriages, go-carts and vehicles in general, and it comprises a plurality of runners which can be suitably supported beneath the body of the vehicle and adjustably attached thereto, so that they can , be raised clear of the ground when they are not needed for use, or lowered when desired I to support the weight o£ the vehicle thereon. I Designs. DESIGN FOR A TEAPOT. C OFF EE POT, ; OR SIMILAR ARTICLE.—M. Weintraub, ! New York, N. Y. This ornamental design for a teapot, coffee pot or similar article represents a teapot of harmonious proportions and highly elaborate ornamentation. Scroll work profusely covers the entire article except the numerous scenes of pastoral and social life pictured around the lower part. 1 DESIGN FOR A SWIMMING BAG.—A. P. Rindskopf, New York, N. Y. This view of a swimming bag of ornamental design, shows an article of square form at the lower half. Half way up the sides, the bag is shaped with two graceful incisions, the top one on each siLe forming the bottom of a wing-like form, two of which constitute the top of the bag.
