MACHINE FOR FoRMlNe ysEAMLEss TUBES.
SPECIFICATION 'forming part of Letters Patent No. 454,030, dated June 16, 1891. Application filed October 20, 1890. Serial No. 368,639. (No model.)
To all whom zit may concern..- A Beit known that I, EDRED W'. CLARK, a citif the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and usefulv Improvements in Machines for Forming Seamless Tubes, of which the following is a full, clear, and exact specification.
The inventionlrelates to the class of machines forforming'seamless- `tubesiot indefi`'A material.
To this end chine which.
in a mamaterial the invention resides transforms 'fibrous beaten into a pulpy, pastry, or semi-liquid -a light seamless tube with the fibers so intertwined and laced as to produce a firm, strong, homogeneous texture throughout the enti-re length of the tube.
Referring to the accompanying dra\\ings, Figure. l is a plan view of the machine. Fig. part cut in central Fig. '3 is a View of the front end of the machine.
In the views, the letter a indicates the base, which is preferably cast to shape. of Viron or steel. In a box b upon the upper surface of the base is formed a bearing for a spindle c, which is adapted to be rot-ated in the bearing ,llby a pulley andbelt ortany confinon for-m of riving-gears. To the front end of this spindle, which is supported by the box I1 adjacent to the box b, is secured a 'mandrel IZ. This mandrel, which is usually formed integral with the spindle, is tapering for a portion of its length, and is provided with a thread of any suitable form and pitch, a portion of this thread' being preferably formed upon `a parallelfpart of the mandrel which lies beneath an 'obpening b2 cut through the top of the A die or shell c 'is secured, preferably by `means of bolts, which pass through flanges upon the parts, tothe front end of the box b around the mandrel. Theopening through the die tapers for a portion of its length substantially parallel with the tapering body portion of the mandrel, and is substantially parallel near the front end, where it encircles the substantially parallel smaller end of the mandrel. The threads at the slnallerend of the tapering portion of the mandrel are made `gradually smaller, so that they will not fill up the space in the opening in the die, along which for a short distance small longitu'dinal grooves fare cut, and to which a number vof"'transvers .l peiifrationsfg-from vthe exterior are bored to permit the escape ofthe liquid' expressed from the substance under compression to form the tube. l
The fibrous material, as paper, asbestos, or any similar fibrous substance, mixed with any suitable sizing or binding material from which the tube is to be formed, is beaten up with a liquid into a pulpy, pasty, or semi- !iquid condition and conducted by any suitable means, as a funnel, tube, or pipe, through the opening Wto the revolving mandrel. 'lhe thread upon the mandrel carries the materialV along spirally down the tapering portion of the die, creases in size, compresses the material and reduces it in. diameter, the Water and moisture expressed by the compression escaping through the perforations provided for that purpose. \Vhen the forward end of the tube being formed reaches the reducedportiou ot' the mandrel and opening in the die, it has become compressed and hardened to the desired degree, airtlis preferably prevented l rom rotaI` tion by the expansion of a portion of its surface into the grooves, while the rear end, which is in a spongy and sott condition, 41s being added to b v the soft pulp which comes down the incline. of the mandrel. .As the fibrous material is brought down the mandrel and reduced in diameter by the rotation of the thread it is laid or built onto the end of the tube sprally, so as to cause the fibers to interlace and form a firm structure.
Fibrous matter is of such nature that the fibers will not interlace and form a firm texture by simply reducing the diameter of tho mass and adding to the end soft matter by direct compression, .and the essential feature 'of my process is the continuous building up of the tube by fibers under a rotary strain as which, as the opening de- IOS) forward compression, fibersV tov intertr'ine and strong tube of produced, which, w 5 non-conducting like, can be use or the the tubes ot varying sha The 15 upon the taper more homogene the threads com the shell, as
