4 Claims.
My invention relates to a machine adapted for the drilling of horizontal holes in the earth under streets, railroad embankments, or the like, in
order to accommodate the laying of pipes for .1 fluids, or to serve as conduits for other purposes.
The primary purpose of my invention is to provide a machine which can be quickly set up and dismantled and will be labor saving, safe in operation, ineXpensive in cost, operation and upll keep, and speedy in its operation. A further object of the invention is to provide a novel construction which is portable, so that when the drilling operation is completed the drilling mechanism and associated parts may be removed l5 from the pipe, within which said parts have been contained, and carried to another drilling job and quickly set up and ready for use. A still further object of the invention is to provide a cutting blade with vprojections on the outer face and an inclined scooped-shaped member secured to the inner face thereof for scooping up the loosened earth and dumping the same on an apron and from there onto a travelling conveyor for conveyance to the rear end of the tunnel being drilled. A still further object of the invention is to mount the drilling portion of my machine in the forward conduit section and to apply to theoutside end of the conduit section a force suicient to cause the drill to progress go-.through the earthy m-aterial, and at the same time advance the conduit section or sections. A still further object of the invention is to firmly support the drill as well as the flaring apron associated with the drill so that these parts may -not be displaced when the machine is operating. While horizontal drilling machines heretofore have been employed of the same general type as the one herein disclosed, I believe I am the first to show so few parts simply and ruggedly 40 constructed and so arranged as to be quickly and conveniently set up and dismantled and highly efficient in its operation at a minimum expense for labor, maintenance and upkeep.
Fig. 1 is a vertical section of the drilling end of the tunnel. Fig, 2 is a sectional elevation of the open end of the tunnel showing the pipe-jacking system. Fig. 3 is an end view of the drilling apparatus. Fig. 4 is a longitudinal section taken on line 4-4 of Fig. 1.
Fig. 5 is a section taken on line 5-5 of Fig. l. Fig. 6 is a vertical section taken on line 6 6 of Fig. 1.
Fig. '7 is a vertical section taken on line 1-1 of Fig, 1.
1938, Serial No. 236,982
In the drawings; The earthy material through which the tunnel is drilled is indicated by the letter A, the piping or tubing for lining the tunnel by the letter B. This tubing is preferably of concrete sections, but other material for forming said tubing may be employed 'and of such diameter as generally used on such jobs. The mechanical conveyo'r C is of the apron type generally employed to convey material from one point to another. D are the supporting rollers for the conveyor C, and E are the supports for said rollers.
An electric motor (not shown) mounted in a box I6 is connected by cable II to a source of electrical power, (not shown), said box l0 is mounted on an angle support I2 extending across the interior of a pipe section B (see Figs. l and '1). The motor is connected to a reduction -gear in box Ill, all of which is of standard construction and no detailed showing of same or a description thereof is believed necessary. A shaft I3 connected to the motor projects from the box I and consists of appropriate lengths coupled together as shown at I4.
The shaft I3 is supported near its end where the drilling blade is carried by a member I (Figs. 1 and 3) which is hung, as at I6, from the inside top portion of a ring I1, which is mounted in the forward end of the first section of the piping B. The member I5 has a loop I8 which circles the shaft I3, (Fig. 1), to vertically support the same. I preferably employ three screwthreaded centering rods I9 having adjusting screws for maintaining said rods in operative position. The inner ends of the rods I9 abut against the inner forward face of the forward section of the piping B, as shown at 2 I, while the outer ends abut against a strap 22 which substantially circles the end of the shaft I3. By means of the rods I6 and the member I5 the forward end of the shaft I3 is securely held in fixed operative position within the pipe B.
A series of sweeps 23 is secured to the shaft I3 just to the rear of the strap 22, which sweeps serve to propel rearwardly the earthy material accumulating on the inclined apron 24, located at the forward bottom end of the piping B, and which apron is retained in position by the ring I1 which abuts against an annular projection 25 on the rear face of said apron 24.
In Fig. 2 I illustrate the manner in which the piping B may be pressed forwardly by a jack B2 horizontally disposed against a block 33 pressing against an abutment 3d secured in a stable inanner, as against an earthen bank 35, or any other firm medium. The other end of the jack .iabuts against an L shaped structure 35, which has a stiifening arm 31 secured to the upper and lower extensions of the L-shaped structure 35. These members 32, 33, 34, and 36 are mounted for convenience in moving on a carriage 38. One face fof the structure 36 abuts against one end of the piping B, thus forcing, through the action of the jack 32, said piping forwardly, and through the mounting of the drilling mechanism in the forward section of the piping B, keeping such -`drilling mechanism in rm Contact with the earthy material to be removed,
By my simple construction and small number of parts the mechanism may be readily mounted in and disconnected from and removed from the piping B when the tunnel is completed. The ring i 'i' can, if desired, be made in sections so that it can be readily removed from the forward end of the forward piping section, but this is not essential, as said ring, can be removed without collapsing the same.
By my construction the equipment can be quickly and conveniently applied to and removed from each tunnelling job with a minimum amount of eifort.
I claim:
