SPECIFICATION forming part of Letters Patent Ad-469,219, dated February 16, 1892.
Application led April 7, 189]..
To all whom t may concern:
Be it known that I, JOHN H. SToKEsBARY, a citizen of the United States,'residing at Highlands, in the county of Arapahoe and State of Colorado, have invented certain new and use-l ful Improvements in Earth-Boring Apparae tus; and I do hereby declare the following to be a full, clear, and exact description -of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to earth-boring ma- A chines, and particularly to such as are used for horizontal boring or tunneling, for laying pipes under street-pavements, lawns, &c. and it consists in certain improvements therein, as will be hereinafter fully set forth, and pointed out in the claims.
The invention is illustrated in the accompanying drawings, as follows:
Figure 1 is a perspective and transverse sectional view of a city street showing my device in operation therein. Fig. 2 is a side elevation of the auger, stem, stock-feeding lever, dac., shown in Fig. 1, considerably enlarged. Fig. 3 shows the swivel O and O in vertical longitudinal section and the valve E in elevation on a larger scale than that shown inFig. 7. Fig. 4. is a longitudinal section of the bit or auger. Fig. 5 shows the same parts seen in Fig. 2, with an alternative form of operating mechanism, said parts being in side elevation. Fig. 6 is a vertical transverse section on the line y y in Fig. 5, looking in the direction of the arrow. Fig. 7 is a similar view taken on the line x in the said Fig. 5.
In operating my device a hose B connectsk a Water-pipe `A or hydrant with the device back of a regulating-valve E, and water is supplied through the hollow stem, sections G, and auger-bit H to the cutting-point, and the earth is thereby softened and the cuttings or dbris are washed back through the bore to the starting-point or pit in which the machine is being operated.
The construct-ion and operation of my device is as follows:
.' dinary or convenient coupler, and the Serial No. 387,917. (No model.)
from the shank to a point between the two 5o blades. The auger stems or rods G are made of ordinary iron tubing in sections of convenient length. The bit H is connected with one of the sections G by a screw or other orother sections are added as the work of boring progresses.
In the construction shown in Figs. l and 2 there is a loop F of tubing formed inconvenient form to act like a common bit-stock, and 6o the auger-rods G are coupled with one end of this loop, and the loop is connected at the other end with a swivel-stem O', which iis in a swivel-barrel C, and has a gudgeon-bearing C2 in a block cG within the barrel C. A stuffing-box C7 at the end of the barrel C forms a close joint around the swivel-stem C', so no water will escape at the point. The swivelstem C is hollow and has an opening or slot C3 in the side, so that water entering the bar- 7o rel O can iow through the stem C.
be connected with any source of water-supply, 7 5` such as a hydrant or the main A.
In practice the swivel-stem O', when the pipe or section G to which it is secured is turned, rotates in but imparts no rotative movement to the swivel-barrel C. This bar- 8o rel, however, imparts the forward movement to the section G when pressed forward by the lever D. In such a movement the block c6 presses against the conical end of the swivelstem, and at the same time forms a bearing for the stem to revolve in, so that said stem will move forward with the swivel-barrel. When the valve E is opened, water will flow through the swivel C C', thence through the crank-loop F, and thence through the augerstem sections G, and be discharged through the orifice H2, between the cutting-blades H', whence it will impinge upon the earth and aid the action of the cutting'blades I-l. The water thus discharged will find its way back 95 through the boring and carry with it the dbris.
The auger is fed to its work by alever D,
which is pivoted to the swivel at d', and to a foot-piece D,which is sustained at d against the wall of the working pit.
In the construction shown in Figs. 5, 6, and 7 the auger-stems are operated by a power device in place of by the crank-loop F; otherwise there is no difference in construction.
J represents a frame-work secured by its rear end to the stufling-boX c of the swivelbarrel C, and having bearings for the swivelstem C2, provided with the bevel ratchet-gears L L', which mesh with the cogs k on a driving-gear K, having the operating-lever K and journaled to frame J at j. The ratchets b are preferably formed integral with the bevelgears. The teeth on each ratchet are turned in opposite directions and the movement in one direction is controlled by a pawl l, pivoted on the swivel-stem, one for each ratchet. (Shown in Fig. 6.) The bevel ratchet-gears L L are loose upon the shaft and are only held against rotation on the swivel-stem by its pawl, when the gear lc, meshing with it, is moved down, the effect being to rotate the swivel-stem. At the same time the other gear ratchet-wheel is rolling upon its gear 7c and upon the swivelstem and continues to do so till the drivinggear K, rocked in the opposite direction from that in which it has been moving, when it rotates the second gear ratchet-wheel and the swivel-stem, while the first gear ratchet-wheel rolls uponits gear K and the swivel-stem, thereby giving to the swivel-stem a rotative movement lin one direction continuously.
What I claim as new isl. In an earth-boring machine, the combination of a water-conveying auger-stem and auger and a water-conveying swivel connecting said auger-stem with a source of watersupply, means for rotating said auger, and a lever D, pivoted on said swivel and' having a foot-piece, for the purpose set forth.
2. In an earth-boring machine, the combination of a hollow auger H, a hollow augerstem G, connected with said auger, a hollow swivel-stem C', connected with the augerstem, a barrel C, in which stem C is swiveled,
a water-supply pipe connected with said barrel C, means for rotating said auger, and a lever D, fulcrumed upon said barrel or other part and having'the foot D', for the purpose set forth.
3. In an earth-boring machine, the combination of a water-conveying auger-stem and auger and a water-conveying swivel connecting said auger-stem with a source of watersupply, ratehet-pinions on said swivel, an operating gear-wheel acting uponl said pinions and having lever K', and a lever Dpivoted on said swivel and having a foot-piece D',
-for the purpose set forth.
