Be it known that I, JUNiUs H. SToNn,la

fcitizenof the United States, residing atNew 'York, county of New `York, State of New tion involves an improved method and appal ratus for continuousl compressing and heatllIlIleCeSSaIl'y.

ing va layer of granu ated cork, so 4that said layer will retain its molded form.

-Heretofore, so far as I am aware, granulated cork has been baked and ressed only in the form of sheets or strips of limited area; and the object of this'invention is tosave labor not only'in the manufacture of the sheets, but in the erection of buildings 'for containing the molding apparatus, since a large number of separate sets of molds will be Of the accompanying drawings, Figure 1 represents a longitudinal section through an apparatus embodying my invention and' by' means of which my improved method may be carried out'. Fig. 2 represents a section on line22onFig. 1. y

Similar `reference characters. indicate .the same or similar parts in both figures.

In the embodiment of the'invention illustrated inthe drawings the apparatus coni-l prises an endless carrier, Iconsisting of a series of Alower sections or containers 10, suitably connected to form an endless chain, each section or container bei-ng formed with a bottom and two ends, but withno side ortions, so thatthe upper stretch ofthe endl carrier will' comprise a trou h ca able of receiving the granulated cori. he endless carrier is mounted on drums or Wheels 11, which are so formed as to engage the endless carrier and positively actuate said carrier.l in the direction of the arrow re resented in Fig. 1 by means of ower suitab applied'to one or both of the s afts of said rums or wheels. A'lheoven is preferably of the horizontal ftype, constructed substantially like a lon'gf lue. It is to be the oven and the mold may be arranged in other than horizontal position. The oven illustrated comprises a casing 12, having an inlet at oneen and an exit-opening at the specification of Letters patent. y Application led October'llv. 1908. Serial No. 838.249.

\ Mounted in the `walls ofthe oven or other# Wise supported are moldfsupporting rolls 13;

An endless presser 14 to coperate with'the sections of the endless carrier is illustrated as -comprising plates, which are hinged or that' the suitable hold the lower stretch of the endless presser presser asa whole may be driven by down upon the material in the mold-sections,

'I employ a series of rolls 15, the shafts of which extend through slots in the sides of the connected together, so

drums or Wheels' 19. In order to f easing and are mounted in bars 16, Which.-

are adjustably connected by screws 177 to, lugs or bosses 18, p ojecting from the sides of the casing. By a plane of travel-'of endless'presser may be varied so as to 'provide for the production of a sheet or strip ofvany desired thickness Within the limits of the adjustments provided, which limits may be from one to =four `inches.

stretches o the endless carrier and endless presser may be supported by suitable rolls 20; The oven may be heated by any suitable means, such as electric heaters or super-v heated steam or hot fair. In 1 I have indicated pipes 21 for theintro ction and escape of any suitablev heating. fluid. Atone end ofthe apparatus a hopper 22 is mounted said ,hopper being adapted to 'contain a suitable quantity of ranulated cork, said cork being deposited rom the hop er directl into one end of the trough formed) by the en( less carrier. The end of the endless presser immediately vin front of the discharge or bottom hopper is inclined, so that the cork taken from the hopper is gradually com ressed as it approaches the oven, said cork eing held ess l 1n compression between the sections 1 0 and the plates of the presser 14 assing through the oven. The oven ma e heated to a temperature of from 400 ahrenheit to 500 Fahrenheit, the speed of movement-bein slow enough so that the combined heat an pressure will condense the layer o'f-cork and usting the scfewsl'the the lower stretch ofthe The return cause the natural ingredients of the cork toserve to bind the parts together,- like a cesheet is heated than when thes lest is4 colds' The escape ofthe gasesweakens the sheet to 7 the lower stretch, which passes through the cooler-casing, is held down by rolls 150, which I vent access of air to the sheet orthe expanof ycarrying out said method, although' not lis @layer Whilein the heater, and then passing the layer through a cooler, vthe inaierial being heating and cooling.

The return stretches supported by rolls 200. -J Suitable pipes 21() are shown, which pipes may be'used for the introduction and escape' of a suitable cooling medium, such as refrigerated air. To presion of the sheet as it passes -through the ovento the cooler,` a suitable housing 23 may be employed intermediate said oven and After the sheet leaves the cooler it 'by any suitable means.

. y Having now described my improved method and one embodiment of apparatus capable limiting myself tothe particular apparatus illusti ated and described, what I claim is`` 1. The-,method of making a cork sheet or strip, the same consisting in continuously forming a layer of granulated cork, simultai neously compressing and heating said layer as it is formed, and progressively cooling said layer, and holding itunder compression during such cooling, themalerial being held substantially air-excluded during the heating 2. The method of making a corkslieet or strip, the same consisting in continuously forming a layer of granulated cork', passing' the layer through a heater, compressing said held substantially air-excluded during'the.

`3. The -method of making a cork sheet or strip, the saine consisting in continuously the layer through a heater, compressing said I resser 140 may be layer while in'kthe heater, and then passing the layer through a. cooler and holding it under compression in said cooler, the matel rial being heldl substantially air-excluded i during the heating and cooling. l 4. The method of making a cork sheet or l strip, the' saine consisting in contiiiuouslyi forming a i layer of granulated cork, passing the layer through a heater, compressing sai layer whilein the heater, coolingtlie layer under pressure after leavingqthe heater, and

passingthe layer through an air-eigcluding housing between the heater and the cooler.

5. An apparatus for the manufacture of continuous cork sheets or strips,l comprising an endless carrier, an endless presser, said carrier and presser being in 'opposition to each other, the opposingsurfaces moving in the same direction, said carrier being substantially unyielding while carrying the material, an oven inclosing portions of the carrier and presser', and means for supporting the portions of the carrier and presser within the oven.

,6. An apparatus for the manufacture of p continuous cork sheets or strips, comprising an endless carrier, an endless presser, said carrier and presser being in opposition to each other, the-opposing surfaces moving` in the same direction, said carrier being substantially unyielding while carrying the-material, an oven inclosing portions of the carrier and presser, rolls for supporting the portion of the carrier within thel oven, and adjustable pressling-rolls bearing on the portionv of the'presser within the oven.

. 7. LAn' apparatus for the nianufacturejof continuous cork sheets or strips, comprising an endless carrier, an endless presser, an oven inclosing portions of the carrier and resser, a cooler, and an endless, carrier an endless presser having portions inclosed by said cooler. i

.8.' An apparatus for the manufacture of continuous cork sheets or strips, 'coniprising an oven, a cooler, an intermediate housing between the oven and the cooler, and endless carriers and pressers, having portions inclosed by said oven and cooler, and adapted ro torni and feed a layer of granulated .cork through the ovenand the housing and the cooler.

.9. An apparatus for the manufacture of continuous cork sheets or strips, comprising a movable compressing device adapted to receive granulated cork in layer form, said devicecoinprising an endless carrier formed of pivotally-connected sections and an endless compressor formed of -pivotallyconnected plates, and a heating device for heating the layer as it is being compressed, said coin- IIO iig
