SANDeDlSTRlBUT'ER FOR LOCOIVIOTIVES.

SPECIFICATION forming part of Letters Patent No. 633,083, dated September 12, 189,9. Application filed January 24, 1899.v Serial No. 703,263. (No model.)

To @ZZ whom t may concern:

Be it known that I, RUDOLF DIEM, a subject of the German Emperor, and a resident of Munich, Germany, have invented certain new and useful Improvements in Sand-Distributers for Locomotives, of which the following is a specification.

Many railway accidents are caused by the slipping of the wheels of the train along the line even when the brakes are so forcibly applied that the wheels do not rotate. There are arranged many systems of sand-boxes on locomotives for the purpose of preventing such sliding of the train, but in emergency it is impossible for the driver to simultaneously put the sand-distributer and the brakel into action.

The object of the present invention is an apparatus by which a sliding of the train is reduced to the least possible minimum by early distributing'of sand. This sand-distributer works only when the danger-brake is putin action, but in braking only a little it remains out of action. This new apparatus has, moreover, the advantage that in case of an accident one can tell di-A as follows: As in Figs. 2 and 3 there is arranged in a casing oJ a channel d going from the top to the bottom, and its exit is ath into a vertical channel c, serving for carrying the sand downward. In the channel c` there is arranged a valve g, frictionally held by a spring f for the purpose of closing the exitopening of channel d. This valve is provided with a finger or a fork h for stirring up the sand in the channel d. The up-and-down movement of this valve is eected by means of an angle-lever m. n o outside the casing and swinging on pivot t',- but, as is to be seen in Fig. l, this angle-lever is by arrangement of a spring p normally moved to the left. In consequence the valve will normally close the opening b. The formation of the angle-lever fdistributer is shown in Fig. 5, wherein the arm 0 of the angle-lever fm, n o is connected through a drawing-gear a with the brake, which comprises two brake-shoes 7c and Z, fasL tened upon the lever-arms u and fu, which swing upon the pivots r and t. At a point 9 on the lever u is pivoted a lever lO, which connects at an intermediate point and through a rod l1 with the ends of the other swinging brake-lever o. The -lever 10 is further connected (at its lower end) with the draw-rod@ of the safety-brake and the drawing-gear :n of the sand-distributer. Should the rod y be drawn in the direction of the arrow e, the brake-shoes will be pressed against the Wheels 12 and I3 and the locomotive will be braked. Simultaneously the sand-distributer comes into action, since the drawing-gear @c brings the valve g into the position shown in Fig. 2, at which time the sand may escape. The arm -n of the angle-lever m n o can, however, be readily operated at will from the engine-cab independently of the actionl of the brakes, this being accomplished through the medium of the drawing-gear- (Shown by dotted lines 6 in Fig. 5.)

I claim as my invention- A sand-distributer for locomotives comprising in combination a casing a forming part of the sand-pipe s and having a channel (l therein leading to a valve-seat b, a valve g to said valve-seat, a lever for operating said valve, a danger-brake and rods for operating the same, together with suitable drawing-gear for connecting the lever with the rods of the danger-brake so that on actuating the latter the sand-distributer is also put into action.

The foregoing specification signed at -MunichGermany, this 7th day of January, 1899.'
