Description

` lnitrd gime at eine Letters Patent No. 106,448, dated August 16,1870.

The Schedule referred to in these Letters Patent and. making part of the'same.

l, WILLIAM ADAMSON, of Philadelphia, county of Philadelphia, `State of Pennsylvania, have invented an Improvement in the Manufacture of Glue, and apparatus for the same, of which the following isa specification..

Nature and Object of the I I wcntion.

My invention consists in the production of sheets of gelatinized size, by causing fluid or semiffluiil size to.tra\erse either with a cylinder or with ali endless apron whileexposed to the air.

`My invention further consists of certain mechanism and apparatus for ihr-ming the 'said sheets, cooling the size, hardening the sheets, and severing the Sallie, thesaid mechanism `and apparatus being too fully explained hereafter 'to need' a' preliminary explanation.

The object of my invention is, economy in the manufacture of glue, by substituting for the manipulative operations heretofore practiced automatic labor-saving'processes and mechanism.

Description of the Accompanying Drawing.

fication of my invention.

General Description. A is a hollow cylinder, the tubular journalslt and a of which are caused to revolve in suitable standvaids or frames B B. Beneath this cylyinder is a trough, on the bottom of which is placed a pipe, D, arranged in the manner shown inv iig. 4 or in coils, or in an'y other manner which will insure. the exposure of as much pipe surface as is possible or convenient to the contents ofthe trough.

Both ends. d and d', of this pip project through one end of the trough, the end (l ibeing continued through the tubular journal a of the cylinder A, and so. far into the interior of `the latter as to extend nearly to the bottom o t the cylinder. This continuation, d, of the pipe D, should be furnished with a cock, e, and the continuation, d', of the said pipe D, should ,communicate with a pump or vother exhausting apparatus, which it has not been deemed neces- -sary to illustrate in the drawing.

ln suitable frames, E, turn two rollers, f f', round which passes au endless apron, F, of wire gauze, the

roller f' being so situated that the apron traverses as near to the cylinder-A as possible without being in absolute contact with it.

In frames G G, arranged inline with the frames E E, revolve three rollers, H, H, and H', and round the .two former rollers passes an endless apron, I, of suitable material, and directly abovethe Vcenter roller and the said frames G G turns a shaft, 71:, in whichare two disks with radial arms, one disk near each end ofthe shaft, the arms of one disk being connected to those ofthe opposite disk by wires m m, for a purpose described hereafter.

Between the rollers H and f is a cross-bur, n, from which project vertical wires p, arranged at equal distances apart, as shown in iig. 2.

The cylinder A is partially filled with salt and ice, or other freezing mixture, and iscaused' to revolve slowly in the direction of the arrow, while the end less'aprons F and I are caused to traverse in the direction of their arrows at the same speed as that of the circumference of the. cylinder A, the shaft h, with its wires 'm m, also revolving in the direction pointed ont.

The size to-bc converted, into glue is introduced while in a fluid condition into the trough C, in which the cylinder A revolves. EThe size adheres to the cool surface of the'cylinder,l and is carried round by` the same, until it arrives at the endless apron ll, onto which it passes in the conditionn of a broad, coutinuons, and gelatinized sheetythecool surface of the cylinder having reducedl it.to this condition.

To facilitate the removal 'of this sheet from the cylinder, a knife, q, may.be' ntroduced at the point shown in fig. 1, this'knife being 'so-formed and situated as to direct the sheetonto the endless aprolrF, by which it is carried to the vel-tical wires p, which cut the sheet into strips,"the latter passing onto the endless apron I, and beneath' the revolving wires m, which sever the strips transversely.

The square-strips of gelatinized size thus produced are now in a condition to he placed on the usual net, and subjected to that hardening process which converts them into glue. l

The old mode of obtaining these desired thin strips of gelatlnized size was to first cast the hot liquid size into long troughs, and after it was reduced, by cooling, to a proper condition, thegelatinized size was cut into slabs, and these were removed from the trough and cut by wires into the required strips, all

'these operations being performedby manual labor.

All that. is necessary to demonstrate the importance of my invention as a labor-saving process is to compare it with the old mode' referred to.

Itiis important that the size contained in the trough should be maintained as cool as possible.

In order to do this I cause the icc-water to be with drawn from the interior of the vcylinder A, through the pipe d, thence through the zigzag pipeD, in the bottom of the trough, and thence through the pipe d', to any suitable exhausting mechanism. The size in the trough is thus exposed to the coolsuiface of thev pipe D.

In order-that the sheet of size,as it is carried by the endless apron F, may be hardened as fast Vas possible, and reduced to an appropriate condition for being severed by the wires, I, in some cases, cover the said apron with a box, of which the dotted lilies t and t', ti". 2, represent the sides, and the dotted llne n,`iig. 1, represents the top.

I introduce a blast ot' cold air into this box, he neatli'the apron, through the meshes of which the ah' passes to the sheet of gelatinized size, and, hardening the same, reduces it to thebcst condition for being cut by the wires p.

It may be remarked here that vthe surface of the v cylinder A should be perfectly smooth; it may, for

instance, be made ot' iron or copper, or tinned plate,` or have an enameled surface. v

The main feature of my invention, namely, the formation of a continuous sheet of gelatiniz'ed size,

muy be carried into 'effect wit-hout the aid ot' the roll-4 er A.

In drawing No. 2 are'two diagrams illustrating lnodllled apparatus for effecting this purpose, and in "these diagrams, -M and M represent two rollers,

round which passes, in the direction ot the arrow, the endless apron N.

Abm'e the roller M is a spout, B, down which partlully gelatiuized or semi-fluid size iscaused to iiow onto the apron, on which the size spreads laterally, thus forming a sheet of'size Iwhich, by the time it hatches the roller M, if the apron be long enough,

wlll be suiciently gelatinized to' be cut by wires.

The apron should be made ot a rubber fabric, or

of -oil-cloth, or of other textile fabric, sized and pol- 3. The combination with a revolving cylinder, A, l

containing a freezing mixture, of a trough or vessel,

C, containing size.

4 Cooling pipes D, arranged in the trough G, in combination with any suitable exhausting apparatus, by which the ice-water in the cylinder may be caused to circulate through the said pipes D.

5. The combination of the cylinder A with an end,- less apron, F, ot' wire ganze` (i. lheknit'e q, arranged in respect to the roller f',

and apron F, substantially as described.

7 The combination of the said endless apron Fand wires p.

8. The combination of' the rotating wires m m with the endless apron I In testimony whereof I have signed luy name to this speeitication in the presence of two subscribing witnesses.
