Specification of Letters Patent;

Application ledMarch 4, 1911. Serial No. 612,181.

To all whom t may cof/wem d eceased, late of lbansdale, borough of Lansdale, State ofPennsylvania, did invent certain new and useful Improvements in Glue- Kettles, of which the following is' a specification.. Y A

The invention relates to improvements in glue kettles orglue mixing apparatus and various objectsof the invention are to provide an apparatus of this class which' is especially simple and easy of construction and eflicient and economical in operation and manufacture, and also which is especially applicable to manufacturev or treatment of glue made from a vegetable base.

Further objects, features and advantages will `more clearly appear' from the detailed l description given below .taken in connection .with the accompanying drawings which form a part of this specification.

In the drawings Figure 1 is a vertical section through the apparatus. Fig. 2 is a top view partly in section 'on the line II-I gf Fig. 1. Fig. the line III of Fig. 1. Fig. l is a bottom view of the apparatus, and. Fig. .5 is a detail section taken on the line VQ-V of Fig. 1.

Referring to. the drawings, 1 represents a main container provided with a steam ]aclret 2 cylindrically arranged about its sides.-

.. The bot-tom 3 of the container inclines downv ardly toward the center where it is provided with a glue outlet 4. At or below the outlet 4 there is a gate valve 5 Vfor admitting or shutting ott' the supply of glue to below from the container. Bolted to the upper part of the container is a cast iron top 6 having a bearing 7 in which a vertical shaft 8 is journaled. The top 6 has two upright members 9 integral therewith which carry Aan 'upper bearing 10 for the shaft S. Secured to the upper end ofthe shaft 8 is a beveled pinion 11 which meshes with a beveled pinion 12 secured to a shaft 13 journaled i'n bearings let and `15 on the uprights 9, Gn the shaft T113 are fast and

loose pulleys

16 and 17 so, that the

shafts

13 and 8 may be driven from any suitable source of tand power. The apparatus-is supported by lugs 18 integral with the main container, which lugs may be bolted to the floor and the outlet 3 is a transverse section on part of the bottom 3- extend doW1 1 through the floor tothe room below to which glue is supplied from the apparatus.

Secured to the lower end of the shaft 8 at 19 is a stirrer 20. For this purpose the stirrer 20- is enlarged at 19 and is provided with a cylindrical opening into which the shaft 8 extends as shown by dotted lines.

rateatea sept. i, 1era..

A. set` screw may be used to firmly secure the shaft to the stirrer. The stirrer 20 is made of one integral casting having integral radial arms 21 extending horizontally` in one direction substantially to the in side wallof the container. rlhe stirrer also has integral radial arms 22 extending horizontally in the opposite direction and in the same vertical plane as the arms 21. The arms 2.1 carry at their outer ends an integral upright or vertical member 23. The .arms 22 only extend about half way from the center of the stirrer to the inside wall of the container and carry at their outer ends an integral vertical or upright member 2-1 which travels in a circular path between the axis of the stirrer and the path taken by the upright member 23. A slight space is provided between the upright member 23 and the inside wall of the container. Y

The underneath or lower surfaces of the arms 22 are beveled off or inclined as shown in Figs. 1 and 5, in a direction to tend to force the glue downwardly. The arms 21 are also beveled olf or inclined o n their lower sides in the saine manner and in a direction to force the glue downwardly. The upright member 23 is beveled on' or inclined on its inner side as shown in Fig. 3, in a direction t0 force the glue or mixture inwardly. The upright member 2e is beveled olf orv inclined on lits outer side, as shown in Fig. 3, in a direction to force the glue mixture outwardly. Integral with the stirrer 2O is an open.

In order to accommodate different sized batches and different spaces into which the apparatus may be putthe apparatus is made extensible or adjustable. For this purpose ,ttension of theA container is L avhici also has steam jacket i2 that the co tainer is med of e of cylindrical sections superpose@ another. Steam pipes :'29 and l5 the jacket d pipes 3l and pipe 33 also lev 2 for dratvine' provi the shalt 8 as 'cy tiri-er extension 3e is prov arms 3G and 37 like the ari s 2i and respectively, in every partie ...il also With-

upright members

38 and 39 like the upright members Q3 and 24, respectively. lt will thus be seen that the sizeof the apparatus may be adjusted toA suit require-y ments.

On one side of the top piece the container is covered by a plate 40 bolted to the container. piece 6 the container is provided with a cover 41 hinged to the part 6 at 42 and provided with a handlet for lifting the cover to admit of the glue materials being placed in the container. Y

The glue or glue materials are placed in the apparatus and the stirrer set in motion to` thoroughly mix the same and stir the glue. The steam jackets will serve to lkeep the bath at the proper temperature ir" necessary. After -being'fully treated the .gate valve 5 may be opened and the screaT i6 Will readily force the glue through the glue outlet to the roomlbelow. The particular' larrangement of stirrerA shown is found esi ent No..'13,l36.' The glue rthere described is pecially advantageous in the preparation of vegetable glue or glue made from a vegetable base and the particular beveling of the stirrer members is ,found advantageous in this regard. The 'inclination of the botvtom' toward the outlet makes more easy the Withdrawal of thebatch and the Vmember 25aids in this respect.

.The particular glue vtor which `this appaiatus -is'eSpeCially adapted is the vegetable glue described in U. S. Letters Patent No5'. 1,020,656. and Reissue Letters Pata colloid-'of greatmviscosity'.formed by dissolving starch flour in Water and caustic soda, and it .apparently contains besides a large proportion of hydrosols an enormous numbero nuclei, and owing to its unusually. high concentration (about.30%) it is prone to gelatinize. The causes for requiring a specially adapted mixing kettle and the functions of: its partsappea'rjto be fas follows: As soon as hydrogel particles begin to form a minute Weblike structure is created with YWalls perhaps entirely invisible under a. microscope, and ras the starch molecule is" vrelatively large, this structure is extensive and Will,` long remain ,like a fluid vUnder 'g the influencev of surface'ten- @n the other side of ythe top' sion np imL suits a Segre,3-J

trous hy egel groups l `ifor any length. er time attach themselves thvrcto strongly is not( sutiicient to remove these aggregations bodily but they must be desegegated by breaking down the invisible dividing Walls and ltearing up the ropy structure.

In the apparatus shown and described, the upright members-23 and 28 and bottom scraper 25v ruiming close to the Walls of the container, not only serve to prevent the gelatinous aggregates from collecting, growing and kattaching themselvesto the side and bottom of the container, but also act to desegregate any such masses as may be termed. The intermediate stirring members4 2xt and 29 act to desegregate or prevent segregation in the body of the glue mass by tearing through the segregation walls` liberating the contents of the segregation cylinders, etc. and disintcgrating and distributing ,the fragmentary parts of these Walls.

The screw blade '96 operating in the glue outlet acts to stir and desegregate the glue -in the outlet when the valve 5 is closed, and

this screw blade 26 is of such size and shape that it will not pack anysolid material (as thestarch flour suspended in Water) in the outlet when the outlet is closed,` but upon opening the valve 5 the blade torce the glue through the outlet. Although the improvements havebeen described in great detail it is not desired that the invention in its broadest aspects be limited to such details except as clearly pointed out in the, appended claims, since many changes and modifications may -Well be made Without departure from the spirit and scope of the invention in its broadest aspects. o i n Having thus .fully and clearly described the. invention what is claimed and desired to be secured by Letters Patent, is: l. A glue kettle A comprising a main container having a heating jacket .about Iits sidesl and an 'outlet` from its, bottom, the bottom inclining downwardly tovvard said outlet, a valve in said outlet, a` stirrer in the 26 acts@ f containerhsaid stirrer .having radial arms 4 the container and carrying an upright mem'- bei` which runs near the inside wall of the container; and the arms extendingin the opposite direction being shorter than said 'first mentioned arms and carrying an upright vmember which runs intermediate the center of the kettle and the path of said first mentioned upright member, said arms being beveled on their underneath sides in a direction to force the glue downwardly, said first mentioned upright member being beveled on its inner side in a direction to force the lue inwardly, said' second mentioned upright member being beveled on its outerfside in a direction to force the glue outwardly, a screw carried by said stirrer for forcing the glue out through said outlet, and means for operating said stirrer. j

2, A glue kettle comprising a main container having an outlet from its-bottom, a stirrer in the container, said stirrer having radial arms extendingin opposite directions in substantially the same plane, the arms eX- tending in 'one direction nearly to the inside wall of the container and carrying an-upright member which runs near the inside wall of the container, and the arms extending in the opposite direction being shorter than said first mentioned arms and carrying an upright member which runs intermediate -the center of the kettle and the path ofsaid iirst mentioned upright member, said arms being beveled on their underneath sides in a direction to force the glue downwardly, said i rst mentioned upright 'member being beveled on its inner side in a direction to force the glue inwardly, said second mentioned' right member which runs near the inside wall of thecontainer and also carryin an upright member which runs interme iate` the center of the kettle and the path o'f said first mentioned upright member said first mentioned upright member being beveled on its inner side in a direction to force the glue inwardly and 'said second mentioned upright member being beveled on its outer side in a direction to force the glue outwardly to more effectively stir the glue, said means for .forcing the glue through said -outlet comprising a screw integral with said stirrer.
