- MORRIS 11. KEELE OF SABETHA, KANSAS! MAuHmE r03 LAYING PIPES.

'and useful Improvements in Machines for Laying Pipes; and 1 do-herehy declare the following to he a full, clear, and exact description of the invention, such as will en-' able others skilled in the art towhieh it appertains to make and use the same.

'lhis invention relates to machines for laying pipe, the object of the invention heing to provide a machine vwhich can he operated to push a P1I)Q,'S\1('l1 as a gas on water .pipe, throng-h the ground from one ditch or excavation to another.

\Vith this and other objects in view the invention consists in certain novel features of construction and combinations of parts as hereinafter setforth' and pointed out in the claims.

In the acconipanving drawings, Figure 1 is a vpe as icctive view of a machine en'ihody- Fig. '2 is a transverse sectional, view, and Fiq; 3 is a detail view.'

1 represents a base on which rails or flanges '2 are located parallel with each other and spaced apart.each of. said rails -or flanges being provided in its inner face with a groove 3. A longitudinally lnovahle member 4 is mounted on the base, 1 between the flanges-2 and is guided in the grooves in said fl anges,such construction insur- Qing the accurate longitudinal niovementot' the member 4 and preventing the same from having either lateral or vertical play. The member 4 'is provided with two rows of teeth which form rack-hars- 5 to he. engaged by gears 01' pinions 6-. These pinions or gears are mounted on a shaft 7 having bearings standard-s Fl on the flanges 2 preferably some distance removed from respective ends of said: flanges. 'lhe gears or p'nions (tare provided in their inner faces with angular recesses for the reception of similgaigly shaped hubs on-v ratchet. wheels 9 and; the latter are provided in their inner tat-es with annular recesses to receive simil arlv shaped: hubs on other ratchet wheels 10. The ratchet wheels are secured togetl-ior and to the gears or pinions 6. ()ne end of a lever 11. is mounted loosely on the shaft 7 between the inner ratchet wheels 10 and this lever has loosely mounted thgeiem --.so as to Specification of Letters,Patent.

.\lu-thcl' ball 12 forming dogs It is carr ed hiy the lever for engaging the inner ratchet wheels 10.. Springs ltF are employed for the dogs.

said springs heing fixed at one cud and adapted near their free ends to engage pins 10* on the hails 12, 12, so that one pair of dog or-the other can i held out of operative relation with th ir ratchet wheels while the ether dogs are disposed in opcran apparent that as one pair of dogs is in operativerelation toone-pair of ratchet wheels and the leveris operated.motion will he transmitted through the gears or pinions and rack-bars 5 to the member -t for moving:-

the latter in one direction. The teeth of the ratchet wheel "ltlare'disposed inthe opposite directionfrom. those ot Rt-lie ratchet wheel I9, so that when the. dogs, 11 are in engagement with the ratchet wheels 10 and the dogs 13 are'out of engagement with the ratchet. wheels 9. and the lever is oscillat d, the member 4 will he. moved longitudinally in the reverse direction. 7

Located at each end of the member 4 are two standards 15 1:"). between which clamping jaws 1 6 and 17 are disposed. The

clamping jaw H5 is fixed and the clamping V jaw 17 is vertically movable,springs 1.8 tending to move the upper jaw 17 upwardly. A cam 19 is'iuounted hetween the standards 15 over the movable. clamping jaw 17 and is provided with a suitahlel lever for turning itto clamp a, pipe 20 bet ween the jaws. The machine is placed in a ditch or excavation and may be anchored therein hy means of suitable spikes passed through perforated lugs 21 on. the base 1 and driven into the ground. If desired a'hack hra a: 22 may he em doyed, -sa.id brace comprising memhers 23 to be. driven into theside walls of the:

excavation,' an a ched n'u phcr L3 connecting: the members 23 and extending from side to side'ot the excavation so as-to permit the passage of. the pipe underit, and rods 2t extending from thesehinlbers to one'end After the machine has been ancl iord in the ditch or excavation, aseetion ofpipe is passed through the clamps at respective. ends of the member 4. and caused "to hrojtsct a suitahlc. distance beyond tho forward end of the latter. The forward end of the pipe is provided with a pointed plug 25. The

pushed into the ground forwardly of the ditch or excavation. When the member 4 shall have reached the forward end of its throw, the clamps at respective ends of said member will be operated to release the pipe and, after shifting the dogs, the lever 11 will be again oscillated and the member 4 moved back under the pipe. The clamps will then be operated to .again secure the pipe to the member at and, after the dogs shall have been again shifted, the oscillation of the lever 11 will cause the member 4 to again more forwardly and the' pipe to further penetrate the ground.

When it is desired to lay a lead pipe, the machine will be operated to force an iron pipe through the ground from one cxcava-e tion to another, in the manner above explained. The pointed plug will then be removed from the. forward end of the rigid iron pipe and one end of a. lead pipe will be coupled thereto. The machine will then be operated haelnvardly so as to pull the iron pipe back and thus thread the lead pipe through the hole made by the iron pipe.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is,---

1. In a. machine for laying pipes, the combination with a base, a longitudinally movable carriagc thereon provided with two rack bars, andwith clamping jaws for rigidly clamping a. pipe between them and restraining it against endwise movement in either directi n with relation to the clamp,

of a shaft mounted on the base, gear wheels on the shaft which mesh with the rack bars, two ratchet wheels having their teeth arranged in opposite directions connected with each gear, and. pawls connected with the operating lever and adapted to engage the ratchet wheels, and positively move the carriage and pipe in either direction, substantially set forth.

2. The combination with a base provided with standards, a carriage movable on said base, said carriage provided with two rows of rack teeth, and means for clamping a pipe to said carriage, of a transverse shaft mounted in the standards of the base, pinions on said shaft and meshing with the rack teeth on the carriage, two pairs of ratchet wheels on said shaft and rotatable with said pinions, a lever mounted on the shaft between the pairs of ratchet wheels, and two sets of dogs cooperating with the ratchet wheels of the respective pairs, and all of said dogs disposed to be operable by said lever to turnthe pinions in one direction or the other.

3. The combination with a base, a carriage movable thereon, means for securing a pipe to said carriage, and means for moving the carriage, ofan arched back brace, and means connecting said arched back brace with the base.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
