EDWARD HUBER 'AND HENRY M.. BARNHART, OF MARION, OHIO.
METHOD OFUNLOADING GRAVEL-CARS.
SPECIFICATION forming part of Letters Patent No. 315,410, dated April 7, 1885.
Application filed January 23, 1885. (No model.)
'[0 all whom it may concern:
Be it known that we, EDWARD HUBER and HENRY M. BARNHART, of Marion, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Methods of Unloading Gravel-Oars; and we do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which the drawing represents as much of a train of gravel or ballast cars as is necessary to illustrate our invention.
This invention relates to an improved method or system of unloading gravel and the like from railroad-cars, by means of a plow or scraper constructed, for instance, like that patented to ourselves on the 14th day of Octoberg-1884, No. 306,688; and it has for its object to provide a system of unloading gravel and ballast cars by means of such plows or scrapers, whereby the unloading may take place while the train is in motion, and in such a manner that for each car-length only half a car-load shall be discharged, which quantity is amply sufticient for ballasting old roads. Such partial unloading has heret0 fore been found impracticable by means of plows or scrapers of the class referred to, owing to the method of operation, which has consisted in connecting the scraper, while placed on the rear car of the train, with the locomotive or tender, whereby it has been dragged over the entire line of cars, while the train has remained stationary, thus discharging a car load to each car length, and necessitating the employment of manual labor when it has been desired to discharge a less quantity. These objections are overcome by our present invention, which will in the following specification be fnlly described, and particularly pointed out in the claim.
which are the ordinary flat gravelor ballast cars.
O designates the plow or scraper, which, as stated, may be of any suitable construction,
' and which, at the commencement of the op- -eration, is located upon the rear end of the rear car of the train. This scraper is coupled or connected with the tender by means of a wire rope or cable, D, extending over the en tire line of cars.
E represents another wire rope or cable, of l the same length as the cable D. The front end of the cable E is made securely fast to the track in front of the locomotive and tender,
and its rear end passes under the locomotive l The dimention, taken in connection with the drawing.
hereto annexed. Then the locomotive moves forward, the train, drawn by the cable E, will follow at one-half the speed, owing to said cable being doubled over the block F. the same time, however, the scraper 0, being connected directly with the locomotiveby means of the cable D, will be moved forward over the cars at precisely one-half the speed of the latter, thus discharging one car-load. while the car moves forward twice its own length. When the forward point of attachment of the cable E has been reached, the scraper will have reached the front end of the completed.
WVe would have it understood that we reserve to ourselves the right to all modifications which may be resorted to without departing from the spirit of the invention.
Having thus described our invention, we
claim and desire to secure by Letters Patent of the United States- The method of unloading or discharging,
front car of the train, and the work will be H gravel and the like from railroad-cars by. means of a plow or scraper, which consists in moving the latter over the cars while the train is in motion in the same direction, substantially as and for the purpose herein set forth.
In testimony that we claim the foregoing as our own we have hereunto affixed our signatures in presence of two witnesses.
EDWARD HUBER. HENRY M. BARNHART.
