GLUE DISSO LI TER AND CONVERTER. 1

Application filed May 19,

Thisinvention relates to glue converters or dissolvers, and particularly to certain improvements in the apparatus patented by Charles M. Zimmerman, #989,101, granted April 11, 1911. a s

The constructionillustrated in this patent shows a glue jelly containing vessel which discharges into a catch basin, which in turn discharge into a glue reservoir or container. The vessel and the catch basin are illustrated as being disposed within an outer tank and steam is illustrated as being discharged into the interior of this tank and circulating around the glue dissolving vessel and around the catch basin. In this construction, however, the catch basin is separated from the glue dissolving vessel so that steam circulates not only around the dissolving vessel and catch basin but enters into the dissolving vessel and comes in contact with the glue. Inasmuch as itisessential that the glue shall be mixed in certain quite accurate proportions with the water so as to give a certain definite consistency to the glue, the circulationofthe steam in contact with the glue tends to cause the glue to take up an additional amount of moisture and thus change the consistencyfrom what has been predetermined. i a

The general object'of the present invention is to provide a construction of this character wherein the glue dissolving vessel has steam-tight contactwith the catch basin so thatthoughthe dissolving vessel may be removedirom. its engageni'ent with the catch basin to permit the thorough cleansing of the catch basin, yet the steami will not come in direct contact with the glue. 1 T

A further object is to provide a screen disposed within the catch basin for the purpose of preventing the passage of any undissolved glue into the I glue reservoir..

Other objects will appear, in the course of thegtollowing description. 1

(My invention is illustrated in theiaccompanying drawing,iwherein p a The figure is a vertical sectional view througha glue converter constructed in accordance with my invention .Reierringto thewdrawing, 10 designates an outer vessel or tank, which issupported in spaced relation by means not shown to a dissolved glue tank 12, beneath which is a tank 13 for the water of condensation. Disposed withinthecontainer or tank 10 is a circular 1927. Serial No; 192,666.

the melted glue chamber 12 so as to discharge melted glue thereinto. This catch,

1 basin 1 1 is held in position within the tank 10 in any suitable nanner as, for instance, by the outwardly projecting centering arms 17. The upper end of this catch basin is formed with an overturned head 18, and dis posed within the catch basin and resting upon a the lower end thereof is the screen 19, this screen acting to retain any lumps of undissolver glue and prevent these lumps of undissolved glue from passing downward into the glue pot or glue chamber 12.

Adapted to rest upon and be supported by thecatch basin 14 is the glue dissolving and melting vessel 20. The bottom of this vessel is formed'to provide a bead 21 which fits over the bead 18 and has practically steamtight contact therewith so that the steam can not pass up between the top of the catch basin and the bottom of the vessel 20. Within the circle defined by the bead 18, the bottom of the vessel 20 is perforated, as at 22 so as to permit the dissolved glue to pass into the catch basin. The upper end of the vessel 20 is-provided with handles 23 whereby it may be lifted out of the converter.

The upper end of the converter has attached thereto the inwardly extending flange 24 constituting a drip trough, and adapted to close the upper end of the converter is the cover 25 provided with handles and having a central opening 26. The cover is formed with a flange 27 which isadapted to fit tightly againstthe outer wall of the .tank or steam chamber 10. Leading from the trough formed by the wall 24 is a duct 28 which leads downward and discharges into the lower portion of the tank 10. Thus any water which is condensed upon the conical cover or lid 25 will be discharged downward into this trough 2d and from thence will pass down into the lower portion of the tank.

'The tank is provided with a pipe 29 for admitting steam to the interior of the tank, this pipe at its inner end having a distributor 30 so asto cause the steam to be evenly distributed within the interior of the tank 10. Suitable means is provided for controlling the amount of steam which will enter or controlling the pressure of this steam.

ill

The lower end of the tank 10 is also con nected by a pipe 31 to the water chamber 13 so that Water condensed from the steam can Water supply and provided with a ball cocle or some like arrangement for the purpose of causing Water to enter the cliainbcr in case the watertherein is exhausted. Under ordinary circumstances, however, the condensed steam will supply suliicient Water tovlteep the chamber full. The Water in the chamber 13 will keep the dissolved glue hot.

In the use of this mechanism, the vessel 20 is to be tilled with particles of glue and a sutliciency oifwater applied thereto. This vessel is then set into a. pan until the glue reaches a jelliiied state, and'then the vessel is renmved from this pan and d sposed with in the converter. The cover is then closed and steam admitted to the interior of; the tank 10. The glue Within the vessel 20 will be melted or dissolved very quickly by the circulation of steam around the exterior oi the vessel and around the catch basin and the dissolved glue Wllll'lOW downward into the catch basin and so into the glue containerl2 The advantage of the construction which I have devised over that shown in the patent to Ziinnnerman is that the steam does not come in contact with the glue at all, and funther in thatthe stean'i causes a more rapid dissolving ot the glue by contacting with the bottom of the vessel as Well as the side thereof or v 'iorly ot the catch basin and steam surrounds the catch basin so as to keep hot the glue therein and also surrounds the pipe 16. Thus the glue is not only heated Within the vessel 20 but the glue taliing into the catch basin and somewhat held back by the screen 19 is kept thoroughly heated Without, however, coming in direct contact with the steam.

The construct-ion is such that the interior oi this catch basin may be very readily cleaned by simply removing the vessel 20, and it is obvious that the catch basin'itselt may be so termed as to be readily removable by having the neck 16 extend down through an opening inthe bottou'i of the tank 10. This permits the tank 10, catch basin, and the vessel 20 to be thoroughly cleansed of glue. By separating the vessel 10 from the top of the glue container 112, it is possible to provide a lid 11 on the glue container which will permit ready access thereto for the purpose of noting the consistency of the glue and its character at any time. gluechamber is, of course, provided with a draw-oil cock such, for instance, as that shown inthepatentto Zimmerman, #971,-

The

337, granted on September 27, 1910. The various parts are preferably made of copper and supported upon legs.

Ithas been found in actual practice that ;a glue"converter;constructed in accordance with my invention melts the glue very quickly and:almost instantaneously, and in particular prevents the glue from being contaminated byforeign matter, such as com pounds used in cleaning boilers or steam. generators which would otherwise come into contact with the glueand become dissolved therein in the 1 process of melting or dissolving the glue if the steam came in direct contact with the glue.

The central opening of the cover provides means whereby any steam which escapes between the top of the glue dissolvingvessel and the outerjacltet ortank may pass oil and the water o'fcondensation from such steam is caught by the trough formed by the Wall 24 and carried into the lower portion of thetanlt. The opening 27 also pro vides for the Workman pouring cold glue back intothe converter. By spacing the dissolved glue containing tank 12 from the lower end otthe tank '10, I provide for opening the door 11 and thus permit easy access to be had to the interior ofthe tank 12.
