UNITED STATES PATENT OFFICE.
ABRAHAM SPENCER, GRAMPIAN HILLS, PENNSYLVANIA.
IMPROVEMENT IN DlTCHlNG-MACHINES.
Specification forming part of Letters Patent No. 157,552, dated December 8, 1874; application filed August 3, 1874.
To all whom it may concern:
Be it known that I, ABRAHAM SPENCER, of Grampian Hills, in the county of Clear-field and State of Pennsylvania, have invented certain new and useful Improvements in Ditching-Machines; and I do hereby declare the following to be a full, clear, and exact descrip tion thereof, reference being had to the accompanyin g drawings and to the letters of reference marked thereon.
The nature of my invention consists in certain improvements on the ditching-machine for which Letters Patent No. 132,929 were granted to me November 12, 1872, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to make and the scraper B, which is bent substantially as shown in Fig. l, and its front end connected with the frame by a rod, b. As the head A revolves eabh arm a raises the scraper B, and, by means of the connecting-rod b, the scraper is made to move across the digging-blade on the arm and scrape the dirt from the same onto a table or platform, 0. On this platform are a series of curved arms or scrapers, D D, which are secured on a vertical shaft, cl, revolved from the gearing of the machine. The scrapers D D carry off the dirt deposited on the platform, and the scraper B falls down of its own gravity, to be caught in like manner by the next arm.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isi 1. The scraper B and rod 1), in combination with the revolving digging-arms a a, substantially as and for the purposes herein set forth.
2. The revolving scrapers D, operating on the platform 0, in combination with the scraper B and digging-arms a, as and for the purposes set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 25th day of July, 1874.
ABRAHAM SPENCER.
