This invention relates to an apparatus for marking coal, and it has for its object the provision of means for automatically applying colored stripes to lumps of coal as they are conveyed from one 'point to anotherg of lumps/ofboal, and it has been found to be more desirable to apply paint markings di.
N rectly to the coal. Such paint markings to be effective must necessarily be distinct, and it is also of prime consideration that the machine for applying the marks should be fully automatic. These and other requirements are satisfied by the present invention which is characterized by itssimplicity of construction and its ecient and economical operatione One embodiment of our invention is heren inafter described in connection with the illustrations of the accompanying drawings,
whereof:
Fig., I represents'a side elevation of a con-` veyor for trans orting coal from a sorting station at the mines to cars for shipment, the
marking apparatus being shown mounted above the conveyor. Y
Fig. II is a top plan view of the same.

F ig. VI is an enlarged detailed view, partly in section, of an automatic control valve.-
With reference to FigsfI and H the coal marking devices, comprehensively designated by the numeral 1, are shown in: this instance mounted above an endless belt conveyor 2 which is used for transporting coal froma platform 3 t9 freight cars 4 for shipuch labels have failed to ad.
ment from the mine. Mounted on the conveyor 2 above its'moving belt 5-there is a frame 6 which carries a horizontal shaft 7 upon which the marking devices 1 are pivoted, there being-ample room for the lumps of coal 8 to pass on the belt 5 beneath the shaft 7.
Each coal marking device 1, as best illustrated in Figs. III and IV, comprises a pair of arms 9 pivoted on the shaft 7 and a spray nozzle 10 adapted todeliver a stream of paint to stripe the coal passing therebeneath. The arms 9 are normally inclined to the belt 5 of the conveyor 2 at an angle of approximately 30, and guards 11 are aiixed to the free ends of the arms 9 to protect the nozzles 10 against injury from striking the coals. In order to keep the guards 11 clear of the belt 5 and to absorb the' shock occasioned by the fall of the apparatus, lexible cables 12 are provided, one end of each cable being attached to the frame 6 and the other end being att-ached to a shackle 27 with a spring 13 and an additional shackle 28 on the spring 13 aixed to the guard 11. The arms 9 and guards 11 of each marking device, which are preferably held in parallel and spaced relation to each other by means of pipe spacers 14 and bolts 15, provide protection for a compressed air line 16 and a paint supply hose 17 which extend therealong and terminate in the spray nozzle 10. Suitable brackets 18 hold the air line 16 and paint hose 17 centrally of the arms 9.
A valve 19 vwhich is adapted to open and close upon vertical movement of the arms 9 is shown situated n ar the pivoted end of the marking device. tAl`his valve 19 being in fixed relation to the arms 9 is bodily movable therewith,`whereas movement of the valve stem 20, which fs operated by a lever 21, is restrained by means of springs 22 which are attached tov a plate 23 on the end of the lever 21 by bolts 24 and thumb screws 525i1 Accordingly the valve 19 is adapted to move relative to its stem 2O to cause the air supply line 26 to open and close communication with the line 16.
Both the air supply line 26 and the paint supply line 17 are preferably made of rubber vhose to provide the requisite liexibility.
The operation of the apparatus is as folf lows: The marking devices normally rest with their guards 11 a few inches above the conveyor belt 5 in which position the valves 19 are closed. As coal passes along the conveyor 2 it strikes the guards 11 and raises the arms 9. The guard -11 will necessarily follow the contour of the upper surface of a lump of coal which it strikes,.even though it be irregular, and the guard 11, accordingly, serves to maintain the nozzle 10 at a substantially constant distance from the surface of the lump of coal so as to insure an even distribution of paint over the surface of the lump. As each pivoted arm 9 is elevated the' resulting tension on the springs 22 through the lever 21 operates the valve stem 20 to open the compressed air supply. line 26 and cause a spray of paint to issue from eachv nozzle 10. By suitable adjustment of the thumb nuts 25 the marking devices may be set to operate only upon the passage therebeneath of coals' of a predetermined size. While the conveyor is filled with coals of a size suii'lcient to cause the operation of the nozzles 10, V a continuous stream of paint will issue from the nozzles and cause the coals to be striped in the desired manner. By the maintenance of each nozzlel 10 near the lowest point of its guard 11, the coals, particularly those of regular surface, may be marked with a stripe with clearly demarcated edges so as to present a distinctive appearance.
Obviously the marking apparatus may be situated at any convenient location; either at the mines or elsewhere, and instead of bemg assoclated with an endless conveyor may be affixed to a gravity chute or other types ef conveying apparatus. When the conveying apparatus is comparatively wide a serles of marking devices by side as here shown, whereas with a narrower conveyor a single device may be suf-v 'flc1ent.
While we have illustrated and described one embodiment of our invention, it will be apparent that numerous changes may be made in the form of the apparatus shown Without departing from the spirit of the invention.
Having thus described our invention, we claim 1. lIn an apparatus for marking coal or the like, means for conveying the material to be marked,fmeans adjacent said conveying means in the path of said material and adapted to be raised by the passage of the material therebeneath, said latter means carrying a spray nozzle directing a spray of paint towards said material, a valve associated with said spray nozzle, said valve as said pivoted arm is raised may be situated side being normally closed, and means` for automatically o, ening said valve as said material passes eneath the nozzle.
