CONDUIT SYSTEM FOR VISCOUS MAS'IIC MATERIALS.
Specification of Letters Patent.
Application led October 20, 1916. Serial No. 126,690.
To all whom t may concern: .Y
Be it known that I, HARRY A. CUMFER, a' citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Conduit Systems for Viscous Mastic Materials, of which the following is a specification.
My invention -relates to improvements in conduit systems.
One of the general objects of my invention is to provide a method of and a conduit system to conduct a normally viscous, slow- Vflowing fluid, such as asphalt, pitch tar, or
like materials, or compounds thereo which are substantially immobile at atmospheric temperature and which require application .v
of heat to render them sufficiently fluid to -be transmitted through relatively small A more specific object of my invention is to providea system of pipe-connecting littings and valves for conducting the heated medium, surrounded by an overlying jacket providing an intervening space-for conducting the' heating medium, such as steam,
-hot water or the like,-continuous through the fittings, valves, etc., over and around the interior conducting pipe sections and around the pump that provides the power to urge the liquid through the conduit system.
vUther and further objects of my invention *will become readily apparent, to persons skilled in the art, from a; consideration of the following description when taken inconj'unction with the drawings, whereinz- Figure l shows a pump a receiver, and a schematic arrangement of my'conduit sec- .tions and fittings, parts being broken' away to show other parts in section. n y Fig. 2 is a transverse section taken on line In all the views the same reference characters are employed to indicate similar parts.
vare coated or saturated with an asphaltic 'water orv weather-resistant, such as asphalt, pitch, "tar or compounds thereof, the mate-v rialor materials are` heated in tanks and maintained at asuitable temperature to render them more or less Huid, and while in this state or r:ondition the fabric is passed the conduit pipes.
through the body of fluid mastic substance, thereby saturatin or coatin the more or less porous fabric ase, to ren er it weatherproof. y
This waterproofing material quickly chills and u nless kept at a relatively high temperature, itV becomes inexpedient to supply suiiici'ent power to urge it through the conduit pipes and therefore a heating medium at a sufliciently high temperature is necessary to be supplied along the entire lineof ow or path of the medium to be heated.
In large manufactories, of this character, where more than one tank or asphalt container is used it frequentlyvbecomes necessary, or desirable, to convey the water-proofingmaterial from one/tank to another, or from a central source of supply to any one of a plurality of vtanks associated with respective fabric-moving and coating inachines.
The problemof transferring and distributing the normally stiff asphaltic plastic from place. to place is fraught with many diiiculties. It chills too quicklyto be successfully conducted through ordinary pipes and ttings. It cannot be practically accomplished lunless it be maintained at a temperature at which it will freely flow, otherwise it willclog the pipes, valves and other fittings through which it is caused to pass.
To force the asphalticinaterial through a relatively small pipe requires'it to be heated to and maintained at a temperature of about 300 degrees Fahrenheit. This temperature is attained in the heating medium, such as steam, or water, by confining and subjecting it to a pressure between and 60. pounds per square inch.
In the embodiment `which I have chosen to exemplify my invention, 5 is a jacketed pump driven by a belt that may be applied to a pulley 6. The pump is employed for the purpose of forcin the material through 7`is an inlet pipe or nipple which is preferably connected to a nearby tank, not shown, containin hot mastic to be transferred by the vconduit system, as` to a tank 8, or distributed toother suitabla lill@ receptacles through branch pipes. 'I`he` conduit pipe system consists of an internal pipe 9 through which to convey the heated mastic material and an external Patented Nov. 2'?, 1191??. y
ecl
Owing to the inequalities of expansion and contraction of the parallel pipes I provide expansion joints 11, preferably for the outer pipes, to compensate for the differences in length, due to the differences in coefHcient of expansion or of temperatures to which they are heated.
The expansion joints, of which there may be any desired number in the system, and of which five are shown in the drawings, consist of a packing box l2 for the packing 13, that surrounds the pipe l0 and is compacted and held in place by the surrounding gland 14 that is freely slidable on the outer pipe.
The box 12 is preferably an integral part of the larger flange-box 15, within which to contain the flange coupling 16 of the smaller inner pipe 9. The box 15 is provided with a coupling flange 17 for connection with a similar flange 18 secured to an adjoining section of the pipe 10, as by bolts 19. The one end of pipe 10 enters the packing box 12 and is freely slidable therein to compensate for the relatively changing length of the parallel pipes, being made steam-tight by the packing 13 and the bolts or studs 20-20, which pass through the flange 14 of' the gland 14 and into `the flange 12 ofthe box 12. Sufficient space 21, is left between the pipes 9 and 10, through which the steam or water, under pressure or other heating medium, is designed to pass.
The fittings, consisting of the elbows 22, the Ts 23, and the valve casings 24 are each dual in character. Each of these exterior fittings is provided with an interior spaced apart similar fitting 22', 23 and 24', respectively. The inner fitting, in each case, is held in spaced relation from the outer fitting by suitably disposed chaplets 25. The inner ipes 9 are secured to the innercontained ttings without intermediary expansion joints. The outer pipes 10 are secured to the outer fittings by screw threads or by flanged couplings.
The steam or water space 21, between the inner and outer pipes 9 and 10, is continued by the space 26, between the inner and outer fittings and thus the space for the heating medium 'is made continuous throughout the entire length of the conduit to ermit a continuous flow of the heating medium, in
a path parallel with the flow of the medium to be heated.
A pipe 27 communicates with a space in the jacketed pump 5 and a pipe'28 communicates with the space 26 for the heating medium, in a remote end of the system. Either of these pipes may be vused for the introduction of the heatin mediumL and the other for the drain or disc arge of the same, at the remote end of the conduit system. The valves 29 control the flow of the heating medium. The valve 30 is operated by the hand wheel 31, and controls the flow of the'heated medium through the pipes 9 into the branches 32 and 33 of the system.
I prefer to use steam or water under 50 to pounds pressure per square inch, which can be heated to 300 degrees Fahrenheit, or thereabout, in the interior steam space, whereby to maintain the heated medium at approximately 300 degrees Fahrenheit, or more, throughout the path of its travel.
Having described my invention, what I claim is .1. A fitting for two concentrically-arranged pipe lines, comprising a box for housing the flange coupling of contiguousr gland, having a part to enter the packing box and overlying said end of the outer pipe, and means to draw the gland into said packing box into contact with packing to be contained therein. y
' 2. In a system of the character described for conductingta viscous material comprising an inner line of pipes through which the material is to flow; a pump connected with said line of pipe; a steam jacket surrounding the pump;` an outer line of pipe surrounding said inner line; a steam connection in the outer wall of the pump and expansion joints in the outer line of pipefrto compensate for the diflerence'in expansion of the two lines of pipe.
In testimony whereof I hereunto set my hand in the presence of two subscribing wit-
