ALEXANDER O LSZEWVSKI, OF NEWVARK, NEIV JERSEY, ASSIG-NOR TO THE GELLULOID MANUFACTURING COMPANY, OF NEXV YORK, N. Y.

MACHINE FOR TREATING COMPOUNDS OF PYROXYLINE.

SPECIFICATION formingpart of Letters Patent No. 280,659, dated July 3, 1883.

Application filed May 18, 1883. (No model.)

To all whom it may concern Be it known that I, ALEXANDER OLSZEWSKI,

a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Machines for Treating Compounds of Iyroxyline, of which the following is a specification.

The invention relates to improvements in machines for treating compounds of p yroXyline and analogous plastic materials, and has for its object the rapid and effectual conversion or reconversion of such compounds and the forma tion of the converted or reconverted material into rods, bars, tubes, &c., all as hereinafter recited and set forth.

The particular nature and operation of my improvements will be readily understood from the detailed description hereinafter presented, refereneebeing had to the accompanying drawings, in which Figure l is a central vertical section through the machine. Fig. 2 is an elevation of the same. Fig. 3 is a sectional view on the line 00 00, looking downward. Fig. 4 is an enlarged vertical central section of the plunger. Fig. 5 is an inverted plan view of the same, showing four nozzles. Fig. 6 is an enlarged cen- 'tral vertical section through a plunger having one main outlet and two nozzles; and Fig. 7 is a plan of the same.

In the said drawings, A denotes the head, and B the bed-plate, of the machine, which are suitably connected by and supported upon the columns or bolts (3.

The piston (lettered D) forms a part of. or is mounted upon the bed-plate B, and is of proper size to snugly enter the water-cylinder E and permit the same to have a vertical movement between the bolts (1. The-upper end of the piston D is suitably packed to form a watertight joint, and through the said piston and leading into the cylinder E is a passage, F, which is connected with a suitable source of fluid-supply by the pipe G. Upon the closed end of the water-cylinder E is placed and secured in any convenient manner (in the present instance by the hinged bolts H) the material-cylinder I, which is of proper size to admit the plunger J, and is surrounded by the annular chamber or jacket K, having an inlet,

L, for steam or other heated fluid, and an outlet, M. The material cylinder I is hollow throughout, and in the present instance a removable disk, N, is placed in its bottom; and, if desired, a sheet of non-conducting material, may be placed between the cylinders E and I, the purpose being to prevent the heat from the steam-chamber K from affecting the upper end of the cylinder E. he plunger J depends from the head-A and contains a central chamber, O, and passages P. The central chamber,

0, is provided with an inlet, Q, and an outlet,

1%, whereby steam or other heating agent may be passed into and from the chamber, and the piston thus suitably heated to keep the material passing through it in a proper condition,

as hereinafter described. In the present i11- stanee I employ four passages, 1?,- passing through the plunger J, and the upper ends of the said passages are connected with nozzles S, each having two openings, (0 b, through the former of which the material is allowed to escape, while in the latter is placed the plug 0, which, when removed, permits the introduc tion of means for cleaning the passage. It is, however, plain that the material may be allowed to escape through both the passages a b,

if desired.

In the construction of the plunger illustrated in Fig. 1 the passages P are lined with tubes T, which form part of or are connected with the nozzles S, the lower end of the tubes being threaded and screwed into the bottom plate,

00, whereby the said plate and the nozzles are at once secured to opposite ends of the plunger in a rigid position. In the base-piece x of the plunger J are formed coucavities 0, around the entrance to the passages P, which have the effect of facilitating the movement of the ma- 9o terial into the said passages.

In Fig. 4, I show the construction of the plunger J in an enlarged view. Upon the horizontal outlets a. of the nozzles S may be secured the apparatus for molding celluloid tubes or 5 rods, which is described in my application for Letters Patent of the United States filed April 10, 1883, Patent No. 278,667, dated May 29, 1883, and the material allowed to pass from thesamethrouggl i variousoutlets; orthenozzles 10o D, which carries the materialcylinder ll l'rom S may be employed in exactly the condition in which they are illustrated in the drawings and a single rod or tube permitted to escape from each nozzle. Around the nozzles S, in proximity to the head A, may, if found necessary, be provided steam-chambers V, in order to retain in a softened condition the material passing through the plunger. It will not be necessary in all cases to employ the steamchambers \V; but they may be found desirable under some conditions of the material.

In Fig. 6, I show a modification of the plunger J, illustrated in the other figures of the drawings, the same consisting in having a single passage, 1, through it for the material, the said passage being connected at its upper end with a nozzle having two outlets, \V, as indicated, or with a nozzle having any number of outlets desired. The plunger shown in Fig. 0 has an annular heating-chamber, Z, encircling the central passage, 1, and being supplied with a supply and delivery pipe, (lettered g h, re spectively.) According to the construction illustrated in Fig. 6 the upper contracted por tion ot' the plunger J' extends through the head A, and is screwed into the lower end of the nozzle S, whereby the said plunger and nozzle are secured upon opposites sides of the head A.

In the operation 01' the invention the cylinder 1?] is first allowed to lower upon the piston below the lower end of the plunger J to the po sition indicated in Fig. 2. The material is introduced into the upper end of the materialcylinder 1, the steam or other heating agent having been admitted to the chamber K and the water to the pipe G, whereby the cylinder E is caused to ascend and carry the material-cylinder upward to the position i ndicated in Fig.1 ,in which position the plunger J' (which has become heated by the passage of steam or other heating agent through it) will have entered the cylinder 1, and will bear against the mat c rial, and by reason of the pressure against it, the heat in the cylinder and plunger, and. its movement through the passages 1., the same will become plastic and be converted or transformed into a solid homogeneous mass and discharged irom the nozzles After a large proportion 01 the material has been forced from the machine through the passages l? the cylinder E may be allowed to lower again and an additional charge of material placed in the cyl inder I and the operai ion repeated, as hc'reiir before described.

It will appear plain that any one or more of the outlctmssages I may be employed, according to the circumstances attending the use of coming hardened therein, prove a source of annoyance.

\Vhat I claim, as my invention, and desire to secure by Letters Patent, is'

1. An apparatus for converting or reconvcrting pyroxyline material, consisting of a hydraulic press, an open materi al-cylinder provided with a heating-chamber, and a plunger adapted to enter the said cylinder, and having one or .more outlet-passages for the material, substantially as set forth.

An apparatus for converting or reconverting pyroxylinc material, consisting of a hydraulic press, a 1natcrial-cylinder surround ed by a steam-jacket, and a plunger adapted to enter said cylinder, and containing one or more outlet-passages for the material, and a heating-chamber, substantially as set forth.

3. An apparatus for converting or reconverting pyroxyline material, consisting of a hydraulic press, a materiaLcylinder nrovidcd with a heatin chamber, an d a pl ungcr adapted to enter said material-cylinder, and containing one or more oullet-passages for the material, said passage or passages being capped with a nozzle for giving form to the discharged material, substantially as set forth.

.4. An apparatus for converting or reconverting pyroxyline material, consisting of a hydraulic press, a material cylinder surrounded by a steam-jacket, a plunger adapted to enter said cylinder, and containing a heatingchamber, and one or more outlet-passages for the material, an outlet nozzle or nozzles can ping the passages through the plunger and being provided with a .lieatiing-chamber, substantial] T as set forth.
