ROBERT H. ELLIOTT, OF MEMPHIS, TENNESSEE.
HYDRAULIC EXCAVA'TOR.
SPECIFICATION forming part of Lettem Patent No. 371,561, dated October 18, 1887.
Application filed August 19,1886.
To a. whom, it may concern.-
Be it known that 1, ROBERT H. ELLIOTT, of Memphis, in the county of Shelby and State of Tennessee, have invented a new and Improved Hydraulic Excavator; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a sectional view of a cylinder being sunk and my improved excavator applied to remove the material. Fig. 2 is a sectional view of a caisson, showing the same. Fig. 3 is an elevation, on an enlarged scale, of the lower portion of the excavating-pipes. Fig. 4 is a section on the line 3 y of Fig. 3. Fig. 5 illustrates gratings to be used across the mouth of the receiving end of the dischargepipe. Fig. 6 is an elevation of the lower end of a modification of my excavator to be used with fine material. Fig. 7 is a cross'sectional view on the line a: w of Fig. 6.
My invention relates to the removal of earth, silt, and other materials from the interior of iron cylinders, eaissons, and like structures to receive bridge-piers.
. Myinvention also relates to dredging generally.
My inventionconsists in the novel construction and combination of devices, as will be hereinafter more particularly described and specifically claimed.
In order that those skilled in the art may make and use my invention, I will proceed to describe the exact manner in which I have carried it out.
In the said drawings, A is a depending waterconveying pipe, curved at its lower end and terminating in a contracted nozzle, 0. Con- 40 tiguous to pipe A, and secured to it by braces XV, if desired, is an exit or discharge pipe, N, having a large ingress-opening, B, lying op- Serial No. 211,284. (No model.)
posite to the nozzle 0. The upper end, D, of the discharge-pipe terminates at a point where To the upper end of pipe A is attached a forcepump or some analogous device to force water down said pipe under a heavy head or pressure, and this stream flows from the contracted nozzle 0 toward and into the dischargepipe N. As the stream passes from nozzle 0 into the mouth B of the discharge-pipe, it picks up any intervening earthy or other matters susceptible of being carried by the stream and carries them with the stream out through the discharge-pipe. The lower ends of the pipes are advanced or changed in position to bring the stream successively upon different points of the material to be removed.
If the exigencies of the ease warrant it, I place across the mouth of the discharge-pipe gratings A B, as seen in Fig. 5, to prevent the entrance into the discharge-pipe of mate rial so large as not to be easily discharged.
In Figs. 6 and 7 I show amodification of my invention specially adapted for use in removing silt or other fine material. In this modification I join the entrance and exit pipe, leaving a cut-away portion, S, into which the fine material is drawn.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The combination, with the pipes A and N, the former having the contracted nozzle 0 and the latter the gratings A B, of the braces WV, the whole constructed, arranged, and operated substantially as described, and for the purposes set forth.
