T0 all whom if may concern: l

Be it known that ALFRED FAUVIN JALoU- V BEAU, of Paris, in the Empireof France, vhas invented eertainnew and useful Machinery for the Manufacture of Pipes or Tubes Impervi ons to Water and Air, of which'the following is a full, clear, and exact' description, reference being had to the accompanying draw ings, making part of this specification, in which- Figure 1 is a front elevation, and Fig. 2 a vertical section. The other figures will be referred to and explained hereinafter.

rlhe said invention relates to certain mprovemeilts in machinery for working the process of making pipes or tubes of paper or other tissue. rolledsipwith Amastic interposed' between and uniting the several thicknesses or windings and for coating the outer surface of the pipes or tubes with mastic after they have been formed.

The process for'thc workingof which the said machinery was invented i consists in rolling paper or other tissue to obtain the required thickness of pipe 'or tube onto a manfibrous tissue to be used in forming pipes is rolled up. 'lhis roller is held in any suitable manner in front of an inclined table, b, leadingto a kettle, g, containing the mastic, which during the operation is to be kept in a liquid state by a fire in a suitable furnace below.

The mastic to be used by preference is what is well known in the arts as bituminous mastic prepared from coal-tar or lasp'haltum, but other equivalent mastic or cement may be used. A cylinder, c, with the journals of its shaft mounted in two, standards, ny n, is so placed that when rotated the lower part of its y pcripheryruns in the liquid mastic; and inst over this `cylinder and resting on its periphery is a cylindrical mandrel, k, by preference made of metal, and 'having its journals fitted to turn and slide up and down in slots in the standards n n. One end of the sheet of paper or other tissue is drawn oif from the roller ct and down the inclinedtable b, and applied to the periphery of the cylinder c, to which it will stick by reason of thecoating of mastic on it. The cylinder is then rotated, by which the sheet of paper or other tissue is drawn and passingup in its circuit it reaches the mandrel k, resting by its weight on the cylinder, and is carried between the two. tendant must then strip the end ofthe sheet from the periphery of the cylinder c and press its coated surface to the periphery of the man drel, to which it will in turn4 adhere by reason of having its surface coated with mastic. The

regularly drawn from the roller c, coated with mastic, and wonndnp on the mandre1'.with liquid mastic interposed between the several windings until the required lthickness is obtained. As the sheet of paper or other tissue is carried up bythe rotation of the cylinder from the mastic in the kettle to the rotating mandrel above to be wound up the surplus mastic runs od' and falls back into the kettle, and if thecoati n gof mastic thus applied is found to be too thick4 it can be reduced by increashave the e'ect of squeezing out the surplus mastic. The weight of the mandrel asa genwinds onto the preceding windings to insure adhesion; but when more is required the press'-, ure may be increased b'y any of the known such as weighted or springv levers bearing 'on the journals.

winding motion by applying power by a crank applied to the shaft of the mandrel, as that will give tension `to the sheet of paper or other tissue, and insure tight wind' through the liquid lmastic to. be coated by it,

An ab 4cylinder and mandrel continue to be rotated, by which-the sheet of paper or other tissue isv ing the pressureof the mandrel k, which will eral rule is sufcient to press the successive modes of increasing the pressure of a roller,

Itis preferred to give the ings; but, if desired, the power may be apf plied to the shaft of the lcylinder c, or to. both. `During the windingcare shouldY be taken to prevent the sheet from getting ont of line, which is accomplished ,by means of a horizontal guide-bar, e, suspended by two rods,

d d, from a standard to which they are hinged,

as represented. To prevent the pipe thus to be formed from being cemented to the. mandrel by the mastic a cylindrical sleeve, h (see Figs 3, 4, and 5,) made of paper, is slipped onto the mandrel, which is previously greased or y otherwise lubricated; and to facilitate the putting on of this sleeve a eene may be used `ter the winding has beencompleted; butV it is desirable that such coating or coatings .should be of uniform thickess on any desired number of pipes, and t'o-secnre this result the mastic is carried up from the kettle g by the periphery of thepcylinder c and transferredto the periphery ot the formed. pipe resting and rolling on it; and as the mandrel vand the formed. pipe on it bear 'on the cylinder by a given weight, and that Weight will squeeze outfrom between thesurfaces all above a given thickness of mastic at any period of contact by giving to the mandrel a determined number of revolutions, the re,-

quired Athickness ofcoating will be determined. .To eiect this result the shaft of the mandrel is provided with a pinion, o (seel Fig. 3,)which engages a cog-wheel, p, on the shaft of the cylinder. (Represented separately in Fig; 6.) The cogs are omitted on a segment of the wheel p, and in the rotation, when this open segment reaches the pinion, a hook, q, on the wheel p comes in contact with the `shaft of the mandrel and acts as a stop to prevent the further revolution of the cylinder. Either or both of these modes of stopping maybe used. After the first coating has been put on the Amandrel is'to be lifted oit' and transferredto the table B by the side of the machine, which is done -by two rods, r r, suspended from one end of alever, l. The rods are hooked at their lower ends to take hold of the shaft. of the mandrel. The mandrel, after ,it has been transferred to thetable B, is to be rolled back and forth on the surface of this table, which is to be vcentered w ith sandYY or' etherrearth y granular matter, which `by the rolling becomes embed ded in the coating of mastic. The -table B may be made of stone, or brick, or any other suitable material, properly smoothed, and

`maintained at a gentle heat by a fire below.

After one coat has been thus rolled, a second coat, if' desired, may be put on the same. After the mastic has vbecome suciently set the mandrel can be taken out by standing it on end and giving it a slight knock. As

it takes a' considerable time for the mastic to become thoroughly dry and hard, wooden mandrels of the same .size should .be lprovid ed to insert. in each pipe when the metal mandrel istaken out,so as to prevent 'the pipes from getting ont of shape While the mas -tic vis vsolidifying. Afterward, it' desired, the

inner paper sleeve may be readily .removed by a metallic brush or scraper and the inside of the pipe coated by-simply running liquid mastic or cement through it. .Y What is claimed as the invention of the said ALFRED FAUVIVN JALOUREAU in machinery for making pipes `of paper or. other tissue and liquid mastic or cement is- 1. The mandrel on which the pipe is formed by Winding, in combination with the kettle or othervvessel containing the liquid mastic or cement, and thexicylinder on which the manl drel rolls, and which carries the paper 0r oth -er tissue through the liquid mastic or cement and up to the mandreh'substantially as and for the purpose speciiied.

, 2. The rotating mandrel. and cylinder on which it rolls, in combination with the movable sleeve put on the mandrel, substantially asdescribed, and for the purpose of preventing the pipes, when formed', from adheringv to the mandrel. I

3. The combination ot' the rotating mandrel, the cylinderon which the mandrel rotates, the kettle or other vessel for containing the liquid mastic or cement, and the guide or equivalent means for guiding the sheet of paper or other tissue, substantially as described.
