ARTHUR RIVINGTON MANGNALL, OF CHESTER, AND ROY FORBES IRVING, 0F CLIFTON, BRISTOL, ENGLAND.

EARTH-ROBIN G MACHINE.

Application filed July 31,

T 0 a]? whom-it may concern Be it known that we, ARTHUR RIVINGTON .llIANGNALL, A. M. I. C. E., A. M. I. M. E., a subject of the King of Great Britamand Ireland, and residing at 48, l/Vhite Fr1ars, hester, in the county of Chester, England, and For Forums IRVING, A. M. T. C E., a subject of the King of Great Britaln and Ireland, and residing at 2, Priory Road, lifton, Bristol, in the county of Gloucester, England, have invented certain new and useful Improvements in Earth-Boring Machines, of which the following is a spec1fi cation.

This invention relates to earth boring machines of the type in which the bore is produced by the displacement of the earth due to the action of a ram or pusher operated by hydraulic or other means.

The object of the present invention is to provide an improved arrangement of the hydraulic cylinder and its carrying mechanism which permits of rapid setting of the cylinder and of the ready and accurateinsertion into their operative position of the pipes, rods or the like by which the boring ram is propelled, and which insures the quick displacement of the water from the hydraulic cylinder when a pipe, rod or the like is being placed therein. A further object of this invention is to adapt the arrangement aforesaid for use in the rapid withdrawal of the pipes and boring ram from position after the bore has been produced or for drawing cables, pipes or the like through the bore.

Referring to the accompanying sheet of explanatory drawings Figure 1 is an elevation, and. v

Fig. 2 a plan view of an earth boring machine constructed in one convenient form in accordance with this invention.

Fig. 3 is an elevation, and

Fig. i a plan view of the machine arranged for withdrawing the tubes or rods from the bore or for drawing cables, pipes or the like through the latter.

Figs. 5 to 8 are similar views showing a slightly modified form of apparatus.

The same reference letters in the different views indicate the same parts.

The hydraulic cylinder a containing the piston or plunger by which the pipes b for propelling the ram or pusher are driven forward, is provided with trunnions c which Specification of Letters Patent. Patented Sept, 28, 1920.

1920. Serial No. 400,512.

rest in slots in a frame 03 carried by tubular or like members 6 clamped in place in the hole or pit at the mouth of the bore f being produced. The rear end of the cylinder has a projecting part 7 abutting against a stationary member a carried by the frame aforesaid, the abutting faces being curved so as to permit of the rotation of the cylinder about the axis of its trunnion. A suitable water inlet connection 2' and an exhaust connection j are provided for the hydraulic cylinder with the required control valves thereon. The frame d may be carried centrally between the members e as shown in Figs. 5 to 8 instead of above the same as illustrated in Figs. 1 to 4.

The forward end of the hydraulic cylinder a is held in place in alinement with the bore being produced by a clamp it permitting or the accurate setting of the cylinder. Freferably, the clamp is carried by the front end of the frame (Z supporting the hydraulic cylinder or barrel, and is mounted so as to be capable of both horizontal and vertical adjustment movements.

The pipes which are being propelled by the hydraulic plunger are held centrally with relation to the plunger by a plurality of arms m pivoted upon the plunger which, when the latter is within the cylinder, project beyond the front end of the plunger so as to form a guide for the pipe end. When, however, the pipe is fully expelled from the hydraulic cylinder, as shown in Fig. 1, the catches m project clear of the cylinder and the lower ones can turn freely about their pivots clear of the pipe so permitting of the cylinder being turned about its trunnions to clear the pipe which has been driven into the bore and to rest in an upright position as shown in dotted lines in Fig. 1, where a further pipe can be lowered thereinto as the lunger recedes and the water is released.

he dropping of the new pipe length into the vertical cylinder assists in the rapid expulsion of the water from the cylinder.

The tubular elements 6 upon which the frame at carrying the hydraulic cylinder a rests are preferably two in number disposed in the same longitudinal direction as the said cylinder; the rear end of the frame 613 against which the hydraulic cylinder abuts, beds against the block 0 upon the side of the pit, so as to take up the thrust exerted during working.

and 4 and may be arranged as shown in Figs. 3 and 4, or may rest upon a cross-piece on the members a as shown in Figs. 7 and 8. A bracket 0 with rope pulley p thereon,

, and also an anchor rod 9 for the rope 1', are

. bular elements 0.

attached to the frame and a pipe or rod 8 carrying the double rope pulley t is placed in the cylinder for operation by the hydraulic plunger. The pull exerted on the carria e d by the rope 1- is resisted by the tie-r0 s u attached to the carriage d and to a member v secured in position by the tu- With this arrangement, the one hydraulic cylinder and plunger serves both for producing the bore and for removing the pipes therefrom. The frame may be supported at a point higher than its base and the tie rods u and pulley bracket 0 be similarly elevated in position.

The invention is not to be limited to any particular arrangement of the supporting frame for the hydraulic cylinder, of the hydraulic connections and control fittings, nor to anyparticular means for setting and adjusting the position of the cylinder to direct the pipes into the bore, as these and the other details of the improved machine may be modified to suit any special services or re uirements.

aving now described our invention, what we claim as new and desire to secure by Letters Patent is 1. An earth boring machine comprising a frame having means for clamping the same in a position adjacent to the mouth of the bore to be produced, a second frame adjustably connected to the first frame, a hydraulic cylinder pivotally mounted in the second frame, and a hydraulic plunger in said cylinder.

2. An earth boring machine comprising members adapted to be clamped between opposite walls of the pit adjacent the mouth of the bore to be produced, a frame carried by said members and abutting against the walls of the pit o posite the bore, and a.

pivotally mounted ydraulic cylinder with plunger therein for propelling the ram which produces the bore, substantially as and for the purpose described.

3. An earth boring machine, comprising tubular members with screwed extensions for clamping the same in the pit adjacent the mouth of the bore to be produced, a framecarried by said members and abutting against the wall of the pit opposite the bore, slots in said frame, a hydraulic cylinder having trunnions thereon which enter the said slots, the cylinder abutting against the said frame at its rear end and the abutting faces being curved so as to permit of the rotation of the cylinder about the axis of its trunnions, and a clamp on the frame for the'front end of the'cylinder, substantially as described.

4. In an earth borin machine as defined by claim 1, the provision of pivotal catch pieces upon the hydraulic plunger designed to detachably secure a pipe to said plun er.

5. In an earth boring machine of the kind defined by claim 2,.pivotal catch pieces provided upon the end of the plunger designed to detachably secure the end of a pipe to said plunger.

6. .In an earth boring machine of the kind defined by claim 1, the arrangement whereby the frame, cylinder, and its plunger can be utilized for withdrawing pipes from a bore or for drawing pipes, cables or the like through the latter. 1

7. In an earth borin by claim 2, means combined with said frame, cylinder and its plunger for withdrawing pipes from a bore or for drawing pipes, cables or the like through the latter.

8. In an earth boring machine, the combination with a portable frame having means for clamping its ends between opposite walls of a pit, a second frame cooperating with the first frame and movable into positions substantially parallel to and at substantially right angles to the first frame, a hydraulic cylinder pivotally mounted in the second frame, and a plunger mounted in said cylinder.

. 9. A combination as defined in claim 8 in which the cylinder and the plunger are arranged at substantially right angles to the first frame, a pulley carried by the first frame, a pulley carried by the plunger, and a rope passing over the pulleys and having one of its ends fixed to one kof the frames.

In testimony whereof we have signed our names to this specification.
