MACHINE FOR THE MANUFACTURE OF ASPHALTUM PIPE.

SPECIFICATION forming part of Letters Patent No. 522,946, dated July 10, 1 894.

Application filed December 7, 1892. Serial No. 454,415. (No model.) l

California, have invented certain new and useful Improvements in Machines for the Man ufacture of-Asphaltum Pipe; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Ourinvention relates to anew and very useful machine for the manufacture of asphaltum pipe for general use, the description of which will be hereinafter more fully set forth.

The following description fully explains'the i nature of our said invention and the manner in which we proceed to construct, apply and use the same. We attain these objects by the mechanisms illustrated in the accompanying drawings, in which- Figure l is a perspective View of the machine showing all parts of the mechanism as constructed and operated in the manufacture of asphaltum pipe. Fig. 2 is a perspective view of the finishing furnace, the top of which consists of a suitable metal plate of the desired thickness and of any suitable size. To one side and on top of the plate is placed a suitable sized longitudinal tank for holding prepared asphaltum, and arranged as desired thereon is a coating roller, and on one side of said furnace is placed and made a part thereof a frame, upon which are arranged the heated rollers connected to steam pipes from the boiler or any other suitable device whereby the result of heating as desired may be accomplished. Fig. 3 is a perspective View of part of the concrete screening apparatus which hangs directly over the metal plate or top of furnace upon which the screenings fall, while the pipe is being rolled thereon after being coated. Fig. et is a side view of the three circular knives and the mechanisms for operating the same, and also their relative positions when operated upon by the lever handie, in cutting the pipe in desired lengths during the process of manufacture. Fig. 5 is a perspective view of portions of the adjustable shaft, having at its lower end two or more projecting arms for holding and guiding the fiber bands or cloth as they come from the spools and pass through the asphaltum mixture in the tank. Fig. Gis a perspective view of the outer end of the mandrel or core, and parts of all the mechanisms for operating the same during the process of forming and manufacturing asphaltum pipe. Fig. 7 represents the coupling ends of the mandril or cores, and the manner of coupling same together during the processof forming the pipe around the said core or mandrel. Fig. S represents a portion of the gear wheels carrying the feed belt, which operates and feeds the mandrels orcores during the process of forming or manufacturing asphaltum pipe. Fig. 9 represents aportion of the gear wheels connected to the heated rollers for operating same, in finishing asphaltum pipe.

Y the spools or guide pulleys for feeding off any suitable fiber or cloth Y2 Z spool or guide pulley for feeding off continuous strips of suitable paper Z2 as desired.

By reference to Figs. 2 and 3 itwill be seen that No. 1 is a longitudinal iron tank or kettle of suitable width and depth, and surrounded by brick work if desired, at the bottom of which is arranged the furnace 2, and 3V asphaltum tank. 4- the iron top plate of the steam chest and furnace. 5 the asphaltum coating roller. 6, 7 and 8 the steam heated rollers for nisliing asphaltum pipe. 9 is the lever frame pivotally constructed which operates the heated roller 8 when desired. 10 steam pipes which supply steam or hot air to the cylinder rollers 6, 7 and 8. 11- the gear wheels for operating rollers. 12- frame upon which are mounted and operated the heated rollers. 13m band pulley secured to the asphaltum coating roller. 14roperating and loose pulleys. 15- band pulley. Connected to the screeningA wheel 16, and 17 is the long U shaped screening trough suspended from the ceiling directly over the top plates t of the furnace l. 13 suspended hanger from the ceiling to which is pivotally attached the lever arm 9 for operating the steam cylinder roller S.

In constructing our machine for the manufacture of asphaltum Ypipe for general use, we rst construct a suitable furnace B and upon the same a suitable sized iron kettle or tank A is placed. The outer side is lined up with brick to hold the heat. Arranged on the inside of the said tank A is a stirring or agitating apparatus consisting of a paddle wheel C secured to-the bottom end of a shaft suspended in the center of the tank A by arms DD, and on the top of this suspended shaft is secured a beveled cog wheel E, having a smaller one operating the saine which is secured to the end of the operating shaft F5 and attached to one side of the tank and to the ceiling, is an upright standard U to which are secured two or more guide boxes V2 into which the adjustable shaft V is adjusted into the tank A and out of the same as desired, and held in position by set screw W. Also to this upright standard U are secured three or more large spools. From the lower spool Z 7 strips of any desired width of paper are unwound upon the mandrel or cores Q2, and in like manner are the unwoven or woven strips of burlap Y2 taken off the two spools Y and wound around the mandrel or core Q2 over the layer of paper Z2 Tlieburlap Y2 covers each seam of the paper and the last layer of burlap strip from the second burlap spool covers the last seam made by each layer cf liber or cloth. Before this operation is beg/un,the mandrel or core"Q2 is placed in position as shown in Fig. 1 and into the guide boxes Q-Q, and the feed band R is given one turn around the core or mandrel Q2. This one turn which forms a band like around the mandrel or core, 1s then placed between the two stationaryiguide arms P-P which hold the belt R in one position, at the same time producing a free rcctilinearrotary movement of themandrel or core Q2, thus with great accuracy keeping up the supply of cores or niandrels Q2 by coupling a new section of the core as fast as the feed belt fR requires the supply, and as each section of the core Q2 is covered or the pipe is perfectly formed thereon, it

is run out and cut off by the circular knives Ii-K at the point ofV coupling, when the same is uncoupled and placed in the asphaltum vat 3 beside the coating roller 5, when the same is coated as desired; after which the new formed pipe is removed from the vat or tank 3 onto the heated plate4, over which it is rolled while the sander pulverized concrete is screened down upon .it from the screenings trough 17. After this process has been suitably performed and the required thickness has been produced, the pipe, which continues to retain the core Q2, is then placed between the heated rollers 6, 7 and 8, and under a great pressure is thoroughly rolled smooth, after which it is removed and placed upon racks to harden, when the core Q27 is removed. The core can be removed at anytime, as the firstcoating of paper Z2 is wound around the cores for the purpose of preventing any asphaltum adhering to the cores and enabling the same to beremoved freely.

The operation of forming the pipe over the cores Q2 consists in the following: The ber or burlap strips of suitable width are supplied from spools Y, passing through a pr epared mixture contained in tank A. A suitable composition such as asphaltum, slaked lime, salt, liquid asphaltum, or crude petroleuni may be used. These ingredient-s are kept at a heat of from 350o to 420, and as these strips of fiber or burlap pass from the lsaid mixture they are wound around the whirling mandrel or core Q2, which has been previously wound over by paper strips Z2, and the process of winding the burlap strips when thoroughly soaked in the mixture of asphaltum carries much of the mixture oi `material as it winds around the core and lforms the pipe, which hardens almost as fast as applied. v Y Having thus fully described our invention, what We claim, and desire to secure by Letters Patent, is
