CHARLES A. CANELA, or ELzABETi-I, NEW JERSEY; l
MACHINE FOR MAKING- TUBES AND TIRES. I
To all lwhom t may concern.'
Be it known that I, CHARLEs A. GANDA, citizen of the United States of America', residing at Elizabeth, Union county, New Jersey, have invented a new and useful lm- -provement in Machines for Making Tubes and Tires; and l do hereby declare the following to be a full, clear, and ex-act description of the same.
This invention relates to a machine and process of cheaply and efficiently manufacturing, from paper, tire shoes, inner tubes, envelops, mailing tubes, cans, cups, other receptacles, and practically any article of paper pulp or other plastic material, having tubular or other cross-section after or during the process of making. To this end I have provided 'a machine wherein the plastic material is forced through a die and a mandrel where it is pressed into shape and partially or fully dried as it moves along the mandrel, the desired lengths being cut off and, in the case of tire shoes and inner tubes, cemented together at their ends and then vulcanized.
In the accompanying drawings, showing two of many possible embodiments of the invention, Figure 1 is a side elevation of the machine for forming tire shoes; Fig. 2 is a section of the line 2 2 of Fig. 3; Fig. 3 is an end elevation,partly in central vertical section; Fig. 4 is a side elevation of a machine for forming mailing tubes or other tubular structures; Fig. 5 is a section, taken on the line 5 5 of Fig. 4.; Fig. 6 is an axial sectionl of the machine of Fig. 4, and Fig. 7 is a section taken on line 7 7 of Fig. 6,
Referring first to Figs. 1 to 3, the machine is shown comprising a pulp box 10 having an outlet 11 with which the hollow mandrel 12 coperates to form a die having a crosssection approximating that of the tire shoe.
The mandrel`12 is partly arcuate and partly spiral in its general shape, and is continued up through the pulp box and receives steam hrough the pipe 14, for heating the manrel.
The paper pulp 15, placed in the pulp box 10 through the door 16, Fig. 2, is forced downwardly by air or steam under pressure admitted through the pipe 18, and passes out through the outlet 11 and moves along the mandrel 12, this portion 19 of the ypulp having there the general shape of a segment of the finishedtire shoe. A hollow steambox 20 surrounds this portion 19 almost in Specification of 'Letters Patent.
. contact withthe same, and has live steam introduced thereto through the pipe 21. Any water that may condense in the steam-box 1s carried out through the drain pipe 22. The steam-box 20 is carried on a bracket 24, which may be integral therewith. The inner edges of' the steam-box are provided with flanges 25, to which are bolted the inverted base 2G carrying the mandred 12. 0n this base is carried a web 28 carrying a boss 29. To this web 28 is also bolted the hop er 10.
T e mandrel 12, projects beyond the steam box 20 in anapproximate helix to the point 30 (Fig. n order to press the pulp 19 into shape and to assist in moving it along the mandrel, a pluralityof pressing rollers areprovided, the lower pressing roller 31 and the upper roller. 32 press upon the tread portion of the tire in formation, while the side rollers 34 press the side of the tire into shape. After the pulp passes from the mandrel it is further supported by a supporting roller 35. The rollers 31, 34 and 35 are journaled in suitable brackets 36, 37 and 38 supported on the floor, while the upper roller 32 is journaled in a bracket 40' carried on a fixed shaft 41 in turn carried by a` bracket42' and the boss 29.
'followsz The doughy pulp 15 is put into the hopper 10, and pressed by means of compressed air, steam, or plunger or feed screw or the like. and forced out through the outlet 11 giving to the pulp a cross-section approximating that of the finished tire. Impelled by the ejecting force andl the rollers 31, 32 and 33 the pulp passes along the mandrel and within the steam-box, the
heat from these and the pressure ofy the Patented Nov. 9, 1915. .Application led December 16, 1914. Serial No. 877,496. 1 v
rollers driving out the moisture from the pulp, the steam driven out by the steam-box passing out through the opening at 45. The pulp passes o' from the mandrel, in aproller 35 after which it is cut into the correct lengths for tireshoes, the ends cemented or otherwise 'fastened together and the tire shoe put in molds andA finished by vulcanizing under heat and pressure.
'lhe general arrangement of the machine of Figs. l toi' is similar to that of Figs'. 1.v to 3, except that it is for straight tubular work rather thanfor tire shoes.
In Figs. l to 7 the machine is shown comprising a pulp' box 50 having at its lower part an outlet 51 with which the straight hollow mandrel 52 coperat'es to form an annular die having approximately the same cross-section as a. completed tube. Live steam is fed into the mandrel through the pipe 5l. The paper 'pulp '55 placed in the pulp box through? the door 56 is forced downwardly by air or steam under pres-l sure admitted through the pipe 58 and passes through the opening 51' and moves down along the mandrel 52 between the mandrel and the steam box 60. The `pipe 61 introduces steam to the steam'box and the pipe 62 leads off the water of condensation.
The mandrel 52 extends to a point 70 (Fig.
4) a considerable distance below the outlet 5l, and between this outlet and said point there are placed, in pairs, a plurality of suitvably journaled and driven ,rollers 31 for pressing the pulp into tubular shape and" squeezing the water therefrom. As the vor made into cylindrical containers, paper bags, envelops or other articles. Vith the mandrel 52 curved, inner tubes for tires can be made.
Of course, various other changes may be made -in the machines, process and articles without departing from thescope of the invention as claimed.
I claim as my invention l. In combination,l a pulp box having an opening therein; a mandrel insaid opening and forming therewith a die and extending a d-istance from said opening; and al steam box surrounding said mandrel and spaced therefrom and separated from said die and having an internal diameter greater than the external diameter of said die. V

In combination, a pulp box having an opening therein; a mandrel in said opening and forming therewith a die and extending j a distance from said opening; and a steambox surrounding said mandrel, at the part that extends from said opening, and having an internal diameter greater than the external diameter of said die.
3. In combination, a pulp box having an 'opening therein; a. mandrel in said opening and forming therewith a dieand extending a distance from said opening; a steam box surrounding said mandrel and rollers associatedwith the mandrel between the outer end of the mandrel and the steam box and adapted to squeeze and move the pulp upon the mandrel.
4. In combination, a pulp box having an opening therein; a mandrel in said opening and forming therewith a die and extending a distance from said opening; and rollers associated with the mandrel between the outer en d of the mandrel and the die and adapted to squeeze 'and move the pulp upon the mandrel.

In combination, a pulp box having an opening therein; a steam heated mandrel in said opening and forming therewith a die and extending a distance from said opening; and rollers associated with the mandrel between the outer end of the mandrel and the die and adapted to squeeze and move the pulp upon the mandrel.

a steam-box spaced a short distance from said pulp box and mandrel and conforming somewhat to the shape of and surrounding the latter; inlet and outlet pipes for said mandrel and steam-box; and rollers associated with said mandrel between the outer end of the mandrel and tle steam-box and adapted to squeeze and move pulp upon the mandrel.
7. In combination, an air-tight pulp box having an opening in the lower part thereof; a substantially helical tubular mandrel passing through said opening and forming therewith a die opening of curved cross-section; a steam-box spaced a short distance from said pulp box and mandrel and conforming somewhat to the shape of and surrounding the latter; inlet ancL outlet pipes for said mandrel and steam-box; and rollers associated with said mandrel between the outer end of the mandrel and the steam-box and adapted to squeeze and move pulp upon the mandrel.
