Application filed September 6,1916, Serial No. 118,664.

To all whom it may concern:

Be it known that I, ARNOLD W. PUPKE, a citizen of the United States, and a resident of theborough of Manhattan, city, county, and State of New York, have invented a certain new and useful Machine for the Continuous Manufacture of Cement length, the smaller the pipe ordinarily the section, and each shorter the length of each a so-called bell section has ordinarily had or socket on one end in which the nonupon socketed end of the adjoining section entered, thus serving as a means to center and sustain consecutive sections in proper alinement, cement being usually deposited about the joint. These old forms were expensive to manufacture, their weight was increased and consequently the labor and expense of laying them, particularly because of the cement required, was also increased.

It is the purpose of my invention to so construct a machine that the tile or piping will be produced as a continuous unbroken structure of indefinite length and deposited in the bottom of the trench or excavation where it is to remain.-

Referring to the drawings, Figure 1 is a plan view of the machine; Fig. 2 is a sidewise elevation of the machine, partly in section, taken on the line 2-2 of Fig. 3, looking in the direction of the arrows; Fig. 3 is a front elevation of the machine; Fig. 4. is a transverse vertical sectional viewon the line 14 of Fig. 2, looking in the direction of the arrows; Fig. 5 is a longitudinal and diagonal sectional view on the line 5-5 of Fig. 3, looln'ng in the direction of the arrows.

, In order that the construction and method of operation of the machine may be more readily understood, it should be stated that the bottom of the trench or other surface which the pipe is to be laid, should be prepared and graded prior to the use of the machine. A suitably constructed track, which may beneficially be made of ordinary two by four studding nailed together on the break joint principle, should then be laid in the bottom of the trench or upon the surface which is to receive the pipe, and along this track the machine about to be described will move during the making and laying of the pipe.

Referring to the. drawings, 1 is a rectangular frame upon which the apparatus is supported. It may be made of any preferred material, preferably angle iron as shown, and in any preferred manner.

2, 2, are a series of rollers, preferably in the form of flanged wheels, as shown, upon which the apparatus is supported and moved upon the tracks 3, 3, (see best Fig. 3) which, as stated above, are laid in the bottom of the trench or upon the surface on which the pipe is to belai'd. v

4-is what may be called a plowshare ex cavator. It is made rounding on its forward edge as shown best in Fig.3, and "has a downwardly extending point or forwar end 5-, as best seen in Figs. 1 and 2. As the plowshare extends rearwardly it expands to the right and wardly after I plow, forming mold boar to spread to the rightandleft cavatedby the forward part of the plowshare.

At the rear of themachine and suitably supported upon the frame are what may be ds 6, ,6, adapted called reverse mold boards7, 7, which areso located, shaped and set at such an angle as to draw inwardly again and deposit against the rear part of the cement chamber, hereinafter to be described, this maleft and rolls over outthe fashlon of a railway snow the earth exterial, so that as the machine advances it will be deposited about-and upon the newly made pipe. v

8 is a shaft supported upon bearings 9, 9, upon which is a grooved wheel 10. a

11 is a bevel gear fastened to the side of the grooved wheel 10 which drives the beveled pinion 12 mounted upon a countershaft 13 supported in bearings 14:, 14:, best seen in Figs. 1 and 2, upon which is a pinion 15, which meshes into another pinion 16, which is mounted upon a hollow shaft 17 (see Fig. '5) which runs through the machine, passing throughthe compartments 18 and 19. Upon the shaft and within the compartments is a worm longitudinally feed 20. The forward end of the' compartwhich forms onewell of an anment 19 is partly Y in this annular chamber 22 -mental worm there be eventfailing to feed will also remove from the radial slots, as shown,

nular chamber 22, its other wall being the outer wall 19' of thecolnpartment 19, and is a supplefeed 23, which is connected with the shaft 17 in any Suitable manner and is driven by it.

Above the compartment 18 is a hopper 24 and above the compartment 19 is another For convenience these hoppers as a single structure and divld'ed by a partition 2?. In these hoppers respectively are what maybe called rotary strippers 25 and 26. They are peculiarly shaped devices best seen in Fig. 5, and are in effect solid disks, each inwhich slots the worms engage respectively, so that should any tendency on the part of the material either to adhere to the worms or to ,revolve with the worm shaft, in either longitudinally, then these strippers will not only prevent revolution of the material with the shaft, but worms any part of the material which adheres thereto, and

hopper 24. may be built thus the material will be compelled to feed "longitudinally under the made.

action of the worms. Each of these strippersis mounted upon a suitable supporting axis or center 27 28 (see Figs. 2 and 5) is a wire, cord, or, if preferred, a rubber hose, which is fed from a reel placed in advanceof the 'machine and passes through the hollow shaft 17 and is deposited in or near the center of the core for the pipe as it is being laid.

The operationofthe machine is as follows: The trench made and the track laid therein or thereon as above described the machine .is placed preferably at an end ofthe line of pipe tobe Core-making material, preferably sand, which has been screened, although suitable earth OrequiValent'm'ateriaI may be 'used, is deposited in the compartment 18 through its hopper; 24, and sand, preferably screened, mixed with a suitable proportion of cement: and water, as is well known, is deposited'in the compartment 19 through its hopper'24 It will be noted that the material in the compartment 18 will entirely surround and cover that portion of the worm 20 which is within the compartment and will also solidly fill that part of the comwire, rope or hose 28,

partment19 which -is within theshield 22, and that the sand cement and water will entirely fill the annular chamber 22. The as the case may be,

is unrolled fromits reel and is passed through the hollow shaft 17, asindicated best in Fig. 5, and itsend is made fast to some suitable anchorage. One end of a draft rope' or cable not shown, is attached to a suitable anchorage in advance of the machine and distant therefrom as far as desired, the free end of which is passed around having a series of,

or excavation havin beenthe grooved wheel 10 and carried back again to a suitable source of power, which may be a Windlass, a mot0r,'a tread mill or the like. The power being now started, the machine, under the action of the along the track; the plowshare will out a semi-cylindrical groove or bed for the pipe in the surface along which the pipe is to be laid; the front mold boards of the plowshare will remove the excavated material to the right and left, depositing it by the side of theadvancing machine, and it can not fall back again into the excavation made by the plowshare, because the lower exterior surface of the body of the machine, shown best at 19, in Fig. 4, which extends rearwardly to the point where the pipe forming cement is projected from the machine, will rest always in the bed out by the plow and maintain its contour, and smooth and compact its surface. The traction of the line over the grooved pulley lOj'will powerfully rotate it, and thus drive the chain of gearing described, rotating the hollow worm shaft 17 and the feeding worms 20 and 23 attached to it, so that the worm 20 will continually discharge from the rear of the machine a core of sand or-other material and the worm 23 will continually discharge from the rear of the machine a hollow cylindrical body-of plastic cement, which will surround and be supported by the core ejected by the worm 20. As the plastic cement body is delivered at the rear of the machine, the mold boards 7 7, which, as stated, are located at the rear end of the machine, will draw the material excavated by the plowshare and moved laterally by the front mold boards 6, inwardly against the upper half of the outer wall 19 of the chamber 22, so that as the machine advances, this material will be deposited about and upon the upper half of'the newly made pipe. Thus the pipe will be sustained throughout its lower half by the bed made for it by the machine, on its upper half by the material deposited upon it as stated, and by the core interiorly, until it is sufliciently set or hardened to be self-sustaining, after which it"will of course additionally harden and, as is well known, become monolithic. As the machine advances, the rope, wire or hose 28, as the'case may, be, will be unreeled and deposited in about the center of the core, thus forming continuous removable device extending is made, whereupon the material may be draft line, will move completely washed out in a step of the pipe a matter of depending upon ing may readily washed out. If this device be a rubber hose, which I prefer, then upon the completion'of the pipe forming operation, it may be pulled forwardly afew feet at a time and water under pressure forced through it, so that the core materiab will be by step manner as the hose is step by step withdrawn.

1t w'll be noted that there must be a certain relation between the feed of the'core making material and the mixed sand, ce-

' ment and water by the worms and the forward speed or movement of the machine, so that there will never be any failure on the part of the machine to get out of the way formation, for if it does not adsubstantially the same spee as then the cement and core vance with the pipe is made, material being continually ejected wo pile up in rear of the machine in a shapeless mass or accumulation. Also I prefer to so time the operation of the parts involved that-the cement shall be ejected under suflicient pressure to compensate for the thickness of'the shells 19' and 22.

It will also be noted that be of such length as desired. pletion of one section of taken up and transferred to the next section the track may in advance of the machine and thus be used indefinitely.

Such openbe small, resembling an ,ordinary manhole, or a. portion of the pip,e may be removed for a distance equal preferably to the length-of an ordilna'r. tile of the same diameter, so that after the removal of the core, any such break in the continuity of the pipe'can be quickly and inexpensively arepairedfby setting in a section of tile of the roper -diameter and suitably embedding and 'ncasing it in cement.
