Application filed October .2, 1912. Serial No. 723,618.
To 'all 'whom z't may concern.'
Be it known thatwe, GEORGE B. COLE, a citizen o f the United States, residing at Spokane, in the county of Spokane and State of Washinton, and EDWARD DURYEE, a citizen of the Vnited States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Pipe- Forming Machines, of which the following is a specification.
The object of our invention is to provide a machine by means of which we may make jointless, continuous pipe of plastic material and simultaneously reinforce the pipe as it is formed, whereby the complete pipe combines all of the advantages of metal pipe with the non-corroding qualities of various plastic material, such for instance as cement.
A further object of our invention is to so construct a machine of this character that it may be voperated in a trench and lay the pipe in the trench as it is formed in any desired length and free from joints or cracks; and with this and minor objects in view our invention consists in the parts and combinations of parts as will be hereinafter more fully set forth.
In the drawings, Figure 1 is a sectional view of a ditch in which our machine is positioned for work. Fig. 2 is a side elevation of the machine. Fig. 3 is a sectional View on the line Baa, Fig. 4. Fig. 4 is a longitudinal sectional view of the machine. Fig. 5- is an enlarged'detail sectional view. Fig. 6 is a sectional view through the pipe forming chamber. Fig. 7 is a diagrammatic view showing the three screws. Fig. 8 is a section/on the line 8 8 of Fig.. 4.
1 is'a wheeled truck von which our machine may be mounted' to run on the rails 2.
.3 and 3u are frames suitably secured to the truck and provided with perforated lugs.
4 is a combined feeding chamber and compression chamber 4a having a forwardly eX- tending pipe forming chamber 19 which passes through the frame 3b, the frames 3 and 3b being tied together by means of the rods 6 which pass through said lugs 5. This feeding and compressing chamber is provided with a series of hoppers 7, lin which a suitable feeding screw 8 is mounted,
whereby material is fed at the sides as well as at the center of the feeding and compressing chamber. f
9 is a hollow stationary shaft fixed to the .head 3, and extending through and beyond cured to a driving gear 13', which meshes with the pinion 14, mounted on shaft 15.- Said shaft being journaled in the head 3, and the Walls of chamber 4 as shown.
The shaft 15 may be connected to any suit? able source of power such for instance as the motor 16, mounted on the truck. A compression shoe 17 is mounted on the end of each of the three feeding and compression screw-threads 10, one of these shoes being provided with a port 18 near its periphery.
The pipe forming chamber 19 as stated connects with and extends from the compressing chamber 42, and is flared gradually toward its discharge end in order to reduce friction between its interior face and the mass of plastic material passing therethrough. The pipe forming chamber is provided With a series of longitudinally eX- `tending grooves 20, into which the plastic material is forced, thereby forming ribs on thel exterior of the pipe, which being keyed in said grooves, prevent the pipe revolving as it is formed, thus eliminating any tendency of the pipe to crack or twist underV transverse strains while being formed. These ribs are pressed out in the passage of the pipe through the cylinder, unless they are needed to embed longitudinal re-inforcements. For that purpose, a reel 41 is provided for the reinforcing wire 40 and guide rolls 42 to lead the wire through an opening 43 in the cylindrical casing of the chamber 19. The reel 41 and the rolls 42 are all mounted on spindles in suitable bearings attached preferably to the forward frame 3b. These longitudinally reinforcing wires may be supplied as desired under one or more of the ribs formed by the grooves 20.
Aswill be seen from Fig. 4, the hollow v the trench.
stationary shaft 9 extends into the pipe forming chamber 19, and serves as a core or mandrel around which the plastic pipe is formed.
21 is a guide detachably connected to the discharge end of the pipe forming chamber which serves as a guide or slide to conduct the formed pipe gradually from the pipe forming chamber to the bottom of the trench, and relieve the pipe of all strains and stresses in its descent to the bottom of The compression shoes 17 are provided with a removable face plate 22. A thrust collar 23 is secured to the shaft 9, to take up an thrust that may be communicated to the driving gear 13.
24 and 24 are brackets fixed rigidly to the driving gear 13, and extending forwardly therefrom between 'which are mounted wire feeding rolls 25, which are mounted on a shaft 26, journaled in said bra'ckets 2'( is a bevel gear keyed to the shaft 26, which meshes with the stationarybevel gear 27, having a collar 2 8 through which a set screw 29 is passed thereby keying said gear 27a to the stationary shaft 9.
30 is an idler around which wire passes from the reel 31,'which is suitably mounted on the machine.
32 is a passage formed through the lbody of the driving gear 13 and the collar 12, and opening into the hollow shaft 9, as is more clearly shown in Fig. 4.
Plastic material, such for instance as cement, paper pulp asphalt, etc., is fed by the feeding screws 10 intov the pipe forming chamber 19, and therein formed around the hollow stationary shaft 9 into the pipe, which pipe discharges on to the guide and is thereby deposited in the bottom of the trench as a continuous pipe without joints or cracks.
It is desirable that the cement pipe be'circumferentially reinforced, and for this purpose we feed wire 14 from the reel 31, over the idler 30 between the feeding rol-ls 25, thence through the passage 32 into the hollow shaft 9 from whence it is fed through a port 18 into the pipe forming chamber in the mass of cement, and inasmuch as the shoes 17 are revolved with the feeding screws 10, the wire is coiled in the mass of cement and embodied therein, thereby constituting a reinforce for the pipe.
To reduce friction incident to the drive between the inner face of the pipe forming chamber and the pipe being formed, we give the pipe forming chamber a gradual flare toward its discharge end, in order to prevent the pipe from revolving on the hollow shaft 9. We also provide the inner face of the pipe forming chamber with longitudinally disposed spaced grooves into which cement is forced, thereby locking the pipe against revolution. The ribs formed on the pipe by the said longitudinally disposed grooves in vthe pipe forming chamber may be left on the Vrails formed in sections so that as the machine advances in the ditch, short sections of rails can be laid ahead to carry the machine as it advances or as the pipe is formed. By the employment of our machine, continuous pipe without joint or crack can be formed and laid in ditches for any length.
Pipe formed by our machine combines all the advantages of metal with the non-corroding qualities of cement mortar. The coil remforcement will resist external compression strains as well as internal tension strains. Referring tothe gradual Hare of the pipe forming chamber, we wish to note that this flare is sufficient to allow the pipe to feed zut of the machine when the friction of the moving mass becomes sufficient to insure the with a horizontal forming chamber, of a suitably threaded feed screw mounted to revolve within said chamber without axial displacement, said screw being provided with a compression shoe at its discharge end, saidl shoe having a port for passing reinforcing wire, and means for feeding the wire through said port.
3. In a continuously running machine for manufacturing monolithic pipe, the comb-ination with a horizontal forming chamber, of a suitably threaded feed screw mounted to revolve within said chamber withoute axial displacement; said chamber having longitudinal grooves for the purpose of forming lands on said pipe and means for disposing a reinforcing wire under certain of said lands.
4:. In a continuously runningl machine for manufacturing monolithic pipe, the combination with a horizontal forming chamber flaring out from its central portion toward its discharging end; of a multiple threaded feed screw mounted to revolve within said chamber without axial displacement, said chamber lbeing mounted on wheels and driven forward by the discharged portion of the pipe.
5. ln a continuously running machine for manufacturing monolithic pipe, the combination with a horizontal forming chamber, flaring out from its central portion toward its discharge end, a mandrel in the chamber with its discharge end tapered, a suitably threaded feed screw mounted to revolve within said chamber without axial displacement.
6. ln a. continuously running machine for manufacturing monolithic pipe, the combination with a horizontal forming chamber, flaring out from its central portion toward its discharge end; a mandrel in the chamber with its discharge end tapered, a suitably threaded feed screw mounted to revolve within said chamber without axial displacement, said Haring out of the chamber and the taper of the mandrel coinciding as to the angularity and commencing approximately in the same transverse piane, so as to facilitate the discharge of the pipe.
7. ln a continuously running machine for simultaneously reinforcing and manufacturing monolithic pipe, the combination with a horizontal forming chamber; 0f a suitably threaded feed screw mounted to revolve within said chamber without axial displacement, a mandrel on which said screw is carried, said mandrel extending beyond said Vscrew into the discharge end of said chamber, thus constituting the core for the plastic mass, said screw being provided with a compression shoe at its discharge end, said shoe having a port for passing reinforcing wire, and means for feeding the wire through said port, whereby said screw coils the reinforcing wire while embedding it in the plastic mass.
8.V In a continuously running machine for simultaneously reinforcing and manufacturing monolithic pipe, the combination with a. horizontal forming chamber; of a suitably threaded feed screw mounted to revolve within said chamber without axial displacement, said screw being provided with a compression shoe at its discharge end, said shoe having a port for passing reinforcing wire, and mea-ns for feeding the wire through said port, a head on said screw having a suitably driven gear wheel, said means comprising a stationary bevel gear, a pinion mounted on said head and meshing with said bevel gear, feed rolls revolved by said pinion and a wire reel positively connected with said wire to said feed rolls whereby said screw coils the reinforcing wire while embedding it in the plastic mass'.
9. In a continuously running machine for simultaneously reinforcing and manufacturing monolithic pipe, the combination with a horizontal forming chamber, of a suitably threaded feed screw mounted to revolve within said chamber without axial displacement, a mandrel on which said screw is carried, said mandrel extending beyond said screw into the discharge end of said chamber, thus constituting the core for the plastic mass, said screw being provided with a compression shoe at its discharge end, said shoe having a port for passing reinforcing wire, and means for feeding the wire through said port, a head on said screw having a suitably driven gear wheel, said means comprising a stationary bevel gear, a pinion mounted on said head and meshing with said bevel gear, feed rolls revolved by said pinion and a wire reel positively connected with said head so as to partake in its rotation, said reel delivering the wire to said feed rolls whereby said screw coils the reinforcing wire while embedding it in the plastic mass.
