chines, although I contemplate the use of myv invention in any field for which it is adapted by the nature of my improvements.
An important object of my invention is to provide means to furnish for consumption a regular supply of the adhesive, in sutlicient,`
but not excessive, quantity for current needs, in order to avoid waste of the adhesive, which is usually of a character apt to deteriorate upon unduly prolonged exposure to heat and atmospheric influences, tending especially to dry out, and also to sour and become infected, particularly when a considerable bulk is left in an open vessel, as is the case in such vessels of present day construction, and especially so in the glue-pots. I
Another important object Vof my invention is to provide improved devices for maintaining the supply of adhesive at a proper temperature, and to apply this temperature uniformly throughout the region of the vessel' containing the supply for current'needs, thus obviating the very usual Idisadvantage ofl ordinary containers for adhesive-and especially glue-pots-, in which the water'use'd inthe double heater frequently evaporates to such an extent as not to extendproperly over the portion of the inner vessel containing the glue, so that the latter is not constantly heated throughout, and is not uniformly heated,-
with resultant disadvantage to its condition for use and equally disadvantageous effect due to the necessity for frequent reheatings. Such irregularities also tend to cause great waste of heat in the effort to overcome the' irregularities by forcing up the degree of heat employed.
A still further object of notable importance in my invention is to provide for feeding the supply for current use from a re- .serve supply of adhesive in the jellied form, inasmuch as the adhesive in this state is least subJect to deterioration and can be converted into `liquid form most readily, glue jelly also lending itself readily to inclosure in packages of standard and convenient form, such as cans or glasses, for transportation, and a cognate feature of my invention is the construction and arrangement of my improved vessel so that the standard receptacles, such as cans, can be applied interchangeably to all supply vessels of my improved type, to furnish the reserve supply of adhesive.
In. carrying my invention into effect, accordingly, I may utilize any suitable apparatus for securing the advantages above noted, and the various features of my invention willA be illustrated and described fully in the accompanying drawings and specification and set forth in the claims.
In the drawings Figure l is a plan view of a glue-pot in the construction of which my invention has been employed; Fig. 2 is a view in vertical section of the glue-pot shown in Fig. 1 taken on the line rc2-m2, looking from bottom to top of the sheet; Fig. 3 is a view in vertical section on the line @a3-m3, Fig. l, looking from left to right; Fig. 4 is vertical sectional view, similar to Fig. 2, of a glue pot constructed in accordance with my invention, and provided with a glue-roller coperating with the supply-part, this figure illustrating certain modifications of other features; Fig. 5 shows in plan view and Fig. G in side elevation, a modied form of supply cartridge for glue-compounds, parts being broken away to reveal interior details of construction.
In the embodiment of my invention selected zfor illustration and description to enable ready and complete understanding of my improvements, the part designated by the reference numeral l is the kettle or outer vessel of the glue-pot, and this may be of any `suitable construction and arrangement, being shown as an iron vessel, of a form usual in the art at vthe present day, to contain a bath of water or other suitable heating fluid, 13.
The reference numeral 2 designates the portion which corresponds in function with the usual inner vessel, dip-cone or glue-pot proper, viz., to contain the supply of adhesive for current needs, my use of the expression glue-pot throughout this specification being used for the sake of brevity and not with any technical limitation. In accordance with my invention it is possible, although not essential, to make this supply part considerably shallower than the ordinary glue-pot, holding enough to insure ample feeding of a brush of considerable size dipped in the pot, or a glue roll or other adhesiveajuilying device, such as that illustrated in Fig. l, and designated by the reference numeral l, the surface of the adhesive being, in each instance, at a level corresponding approximately to that indicated by the line 5, in Fig. 2. In accordance with my invention, the supply of adhesive is maintained at the height indicated,by a flow from a reserve receptacle designated in Fig. 2 by the reference numeral G, this receptacle being of any suitable construction, and being shown, in the instance illustrated, as a metal can, inverted, and provided at its mouth with a screw thread 7 applied to a coperating screw thread 8 upon the portion 9 of the inner glue-pot part 10, which latter extends entirely over the kettle 1 preferably, and may be formed conveniently as an iron casting integral with the dip-cone portion 2. This form of screw threaded connection can be seen most clearly in Fig. 3, where it is shown in elevation, but it is not essential, and may be used only when found convenient. Ordinarily I have found that it is not necessary to provide an absolutely air-tight mechanical connection at this region inasmuch as if there is a slight exudation of the adhesive it forms an effective seal, even where there is only a relatively loose superposition of the receptacle upon the heating base.
I prefer to form the portion 9 as a raised boss, for convenience in attaching the metal receptacle, and in order to provide exit for the contents of the receptacle I have shown a channel 11 extending from the surface of the portion down to a point in the dip-cone at a region below the normal surface 5 of the supply of adhesive for current use, the adhesive running down through this channel by gravity when the atmospheric pressure is relieved as above described by 'lowering of the surface by use, so that air can pass up through the channel 11. It will readily be seen from the above description that the supply 50 of adhesive within the ren ceptacle maintains itself by gravity in contact with the portion 9, and when, as I prefer, the supply within the receptacle takes the form of such a substance as glue jelly, as indicated in Fig. 2 of the drawing, the lower surface of the jelly will be softened and liquefied by the heat communicated to it by the iron portion 9, the latter deriving its heat directly from the water bath, or from the heated air or vapor above the surface of the water 13 in the kettle, which may be heated in any suitable fashion, as usual.
As already noted I prefer to facilitate the downward movement of the glue jelly by softening it peripherally, for which purpose any suitable means may be adopted, one convenient form being shown at 14, which designates a cast iron cap of a size suitable to inclose the receptacle 6 when the latter is in place, the cap resting upon, and preferably secured by a threaded joint to, an annular collar 15 surrounding the portion 9 vvand the receptacle superimposed thereupon, and concentrating upon the walls of the receptacle the heat transmitted from the member 15 adjacent to the heating bath. (See Fig. 2).
In order to furnish a continuous supply of water to the kettle, any suitable means may be utilized, but I prefer to provide a reservoir operating in a manner similar to that described with reference to the receptacle for adhesive, and at 25 I have shown such a reservoir, taking the form of a bottle inverted over a pipe 26, or neck, (see Fig. 3) constituting the conduit by which the fluid is conveyed to the interior of the kettle, letting down the water to replenish it at the level indicated at 13, approximately the same as level 5 of the glue, the flow of water taking place when the fluid within the kettle is evaporated to an extent suiiicient to unseal the lower opening 28 of the conduit. This supply is automatic, and if desired I may tending up through an opening 31 in the top of the glue-pot and having means 32 by which it may be placed in adjusted position. The neck 26 of the reservoir may be mount ed adjustably to vary the position of its outlet 28, and consequently the height at which the water bath 13 is maintained, and if desired the neck 26 may have a screwthread, as indicated, to be engaged with a suitable coperating surface on the top 101, as for example the soft metal bushing or packing 27. The reservoir 25 may also have an inlet 33 through which additional supplies of fluid may be introduced from time to time to replace that lost by evaporation, and preferably a closure 34 will be supplied, of any suitable form, being shown, in the instance illustrated, as a stopper. This automatic supply of the feed water to maintain it at the proper height makes it possible to use much less water than is required for the ordinary glue pot, and this reduces the operating expense, for in my improved vessel it is only desirable to have sufficient heating fluid to surround the dip-cone and feed conduit together with the portion 9, and the dimensions of the kettle 1 may be much reduced from those of the kettles in present use. If electric current is used for heating the water, it means the reduction of the amount of current required.
I may provide suitable means to heat the feed-water, such for example as the U-shaped pipe 8O for heating fluid, such as steam, passing through the walls of the kettle, as at 8l in Figs. l and 2, or secured to the bottom thereof as in Fig. 4, where the steampipe 83 is held adjustably by bolts 84 within a chamber 85 cast in the bottom of the kettle, the latter being provided with legs 86 to hold it up at a suitable height above the bench or other support to avoid burning the bench, if of wood, or otherwise injuring it.
Whether the steam-pipes transfix the walls of the kettle or lie in such a chamber, they will preferably be movable to present a greater or less heating area and may have notches or other suitable marks 87 to indicate the degrees of heat which the feed water may be expected to receive from the steampipe in the several adjusted positions of the latter. The pipes may be connected by flexible tubes 8S to a suitable source of steam or other heating fluid, not shown, thus permitting free movement of the supply vessel to different parts of the bench or shop, and the pipes may have a covering S9 of asbestos or other heat-proof material to permit their use as a handle for the vessel.
I contemplate also the use of the reservoir 25 to yield heat to the receptacle 6, and for that purpose may arrange them in juxtaposition, as shown clearly in Fig. l, where the reservoir 25 is shaped to embrace a substantial portion of the periphery of the receptacle 6, and if desired may surround it entirely, as shown in Fig. 4, where the cap 150 is reduced to a shallow cover, and the hot feed water 130 contacts directly with the receptacle 65. A water-sealed feed-water-outlet is shown at 280.
Various forms of eccentric mounting of the reservoir and receptacle may be adopted, to enable one to be turned away from heating relation to the other one, such arrangement being shown in Fig. l, in which the bottle can be swung on its neck away from the cap 14.
' If desired, the rim of the dip-co-ne portion 2 may be provided with a separable, auxiliary rim 40, useful as a scraper over which to draw the brush, and forming a space 4l in communication with the kettle by means of apertures 42 extending inwardly and upwardly through the wall of the supply part 2, just beneath the rim 40, through which apertures 42 vapor finds access to the auxiliary rim and is cooled by contact therewith, the condensate flowing into the adhesive, carrying with it the surplus scraped from the brush and serving to replenish the moisture lost from the dipcone by evaporation ordinarily.
Additional scraper devices may be provided, as for example the wings or vanes 45 depending from the rim 40, with w'hich they may conveniently be cast integrally, extending downward into the portion of the dip-cone containing the current supply, so that by rotating the rim the vanes will be caused to stir and mix the adhesive and condensate.
Another feature of my invention comprises the provision of means to regulate the depth to which glue-sticks or other adhesive-applying devices may be passed into the dip-cone, and as one convenient form of such means I have shown in Figs. l and 2 a member 46 which may be termed a dipplatform, being in the instance illustrated a disk of suitable material, such as castiron, having preferably peripheral slots 47 to receive the vanes 45, which latter may be notched as at 48 to furnish a graduated support for the platform member 46, the latter constituting a false bottom, the height of which can be regulated at will. A stick 49 introduced to the dip-cone, when such a dipplatform is provided, will receive each time a predetermined quantity of adhesive, instead of the irregular amounts taken up when the depth of each insertion is uncontrolled and depends on the careful attention of an operative. There may be considerable variation in the contour and structural detail of the adhesivereceptacle, according to the convenience of those who furnish the charged supply receptacles; the nature of the adhesives used; and the requirements of individual consumers; respect being had also to the shape of the supply vessels in which the receptacles are to be used.
In Fig. 2 the receptacle 6 has approximately vertical walls, while in Fig. 3, a receptacle 60, similar in other respects to that numbered 6, is provided with a plurality of peripheral ridges 61, formed with interior grooves 62 which constitute channels down which may flow freely the adhesive liquefied by the heat from the jacket, which strikes the ridges 61 first and melts the adhesive therein, opening quickly this course of supply, and maintaining it open, a provision especially valuable for adhesives of relatively low' fluidity.
In Fig. 4, I have illustrated a form of receptacle 65 which may be used to advantage with jelliform adhesives of a character which can be readily separated from the walls of the receptacle, the tapered periphery of the receptacle facilitating such loosening of the jelly cone 66, from which is removed a portion of its base before emplace` ment of the receptacle upon the base 90, so that a peripheral space 67 is left to permit uninterrupted downward flow of the ad- FEI:
-hesive as it becomes fluid, this space increasing somewhat as the cone melts away at the heated base 90. The cuttings from the base of the cone may be melted in the dip-cone, as indicated at 68. The receptacle 65 may be used in the apparatus shown in Fig. 3 without a special heating cap 14, as the jelly-cone is quite free from the walls of the receptacle, and will melt and settle down on the base 90 without hindrance, the receptacle 65 serving as a heating cap. So also, while the use of a separate receptacle 6 within the heating jacket affords a cleanly and convenient mode of operation, I wish it understood that I regard the collar and cap portions 14, 15, as available for service as a receptacle, no special arrangement being required, as it is sufficient to shake the jelly from the can 6 into the collar 15 and put the cap 14 in place, in the apparatus shown in Figs. 1 and 2, and the operation will proceed in every respect as hereinbefore described. Furthermore, if it be desired to use fluid adhesives instead of glue jelly, this also can be done with or without the use of a separate receptacle 6, by merely turning` over the member 10, with the cap 14 in place, to a position best understood by holding` sidewise the sheet of draw'- ings containing Fig. 2, with the top of the apparatus toward the right hand, so that the delivery opening of the channel 11 will be presented upward, and liquid of any desired character can be introduced to the receptacle through the channel 11, after which if the apparatus be righted, automatic feeding will proceed as already described.
If preferred, for any reason, the receptacle member 6 may be preheated to liquefy its contents, or may have a permanently fiuid or semi-fluid adhesive therein, and in that event it will be desirable to invert the top 10 before applying the threaded mouth of the can 6 to the base 9, the operation of the parts, when thus assembled, and righted, being in all respects similar to that already described. For the sake of convenience in accomplishing such inversion, I have shown, in Fig. 3, a modified form in which the receptacle base 93 and dip-cone 102 are formed together in a separate part, removable from the main part 101 of the kettle cover, the joint being designated by numeral 100, while 110 designates the supply conduit, and 116 an aperture through -which vapor may pass from the heating bath to the receptacle.
To prevent clogging of the channel 11, I prefer to provide suitable means to hold the jelly cone 50 or other supply stock away from the inlet thereto, as for example the foraminous strainer 95 (see Fig. 2) of metal gauze elevated above the base 9 upon ridges or studs 96 between which the fluid supply,
fiowing through the strainer, may reach the channel 11.
Glue compounds of special values for particular operations, can be made at low cost, and handled conveniently, if the glue-part be segregated from the other parts until the compound is required for use as a fluid entity, for which purpose the glue-part and other parts may be mingled, under the action of heat. Accordingly, in Figs. 5 and 6 I have shown a cartridge or stock receptacle 106, comprising a metal can divided by a partition 107 into compartments closed respectively by a cap 108, one of the compartments containing the glue part 109 while the other compartment may contain any suitable ingredient 0r ingredients 119 for eventual admiXture therewith, su-ch as fluid fuel paste, gum solutions, dextrin, lishglue, and liquefied glue compounds.
In compounds where liquefaction is eected by the addition of acids or alkalis, animal glue will become damaged after eX- posure to their action for a considerable length of time, but no material injury will result from such exposure during the brief period of their admixture in the portion of fluid supply presented for current use. Herein is found one of the valuable features of my novel cartridge with the separating wall confining each part until required for use. In operation of this cartridge, the cap 10S is removed from the cartridge 106, which may theretofore be kept in stock, with its ingredients segregated, safely, subject to demand, and the mouth of the can,preferably threaded, is applied to the base 9 of the form of apparatus shown in Figs. 1 and 2 just as in the case of the cartridge or receptacle 6 already described, when the heated base 9 will cause a melting of the ingredients 109, 119 which will fiow together as a fluid compound into the supply conduit 11, and dip-cone 2 for use. Such a cartridge is novel and will be madeV the subject of generic claims. Y Y
Having illustrated and described my invention thus fully and suitable means for carrying the same into effect, it will be understood that I do not limit myself t9 the specific construction and materia-ls herein shown and described nor in general otherwise than as set forthin the claims read in connection with this specification.
What I claim as new and desire to secure by Letters Patent is 1. In a supply vessel; the combination with a heating base to receive a stock-receptering said heating fluid, to be heated thereby, and means to maintain both said adhesive and heating iuid automatically at the same predetermined level.
3. A supply-member for apparatus of the class described, such as melting-pots; said member comprising a metal cover for said pot and having a supply portion and a reserve cup removable With said cover and in communication With each other, and a heatretaining closure for said cup; and a separable receptacle inclosed by said cup and closure, to furnish the supply; and means to heat said cover; substantially as described.
4. A supply-member for supply-vessels of the class described; comprising a receptacle part having a heating-base for a separable stock-receptacle; means to secure a stoclr-receptacle removably, upon said base; a supply portion in communication With the portion of said base covered by said receptacle when in place thereon, to receive automatically a supply of heated fluid from said receptacle, and a receptacle inclosure surrounding the space occupied by said separable stock-receptacle, to conline the heat from said heating base.
5. A supply-member for supply-vessels of the class described; comprising a heating base for stock-receptacles; means to secure opies of this patent may be obtained for an inverted receptacle removably upon said base with an air-tight joint; an air-sealed outlet through said base to pass the heated contents of said receptacles; and a heating inclosure for said receptacle; said inclosure being adapted to contain a fluid heat-retaining medium surrounding said receptacle When in place.
6. ln a supply-member of the class described; a dip-cone for the current supply of adhesive; a rest therein to regulate the depth to which an article may be introduced into said dip-cone; means to maintain said rest in predetermined position; and means to maintain a current supply of adhesive at predetermined level in said dip-cone.
7. in a supply-member of the class described; a dip-cone for the current supply of adhesive; a scraper-rim; a plurality of stirring-vanes extending into the portion of said dip-cone to be occupied by said adhesive, said vanes being connected with, and to be operated by, said scraper-rim; and a rest adapted to be supported, in adjustable position, by said vanes.
8. A device of the class described; comprising a cast-metal annular scraper-rim having a plurality of depending radial scraper and stirring vanes constructed as a unitary structure therewith, said vanes having their inner upright edges notched; and a separate notched rest-disk to rest in said vane notches and be supported thereby adjustably at predetermined height.
