Claims.

a of sufliciently low viscosity to surfaces that are to be secured to the same or similar surfaces such as, for example, wrapping paper, closures for boxes or cartons, hinged covers for cardboard and paper boxes, wall papers, posters, labels, etc. More particularly, this invention relates to the combination of an improved glue container and spreader.

Among the objects of my invention are to provide a container for glue, mucilage or similar adhesives, which is practically air and water tight; second, to provide a receptacle so constructed that its contents will not be discharged if it is upset in any way; third, to provide a portable and at all times readily usable means for supplying and distributing liquid I adhesives;

fourth, to provide a container that will supply a regulable amount of efliuent at all times preferably in a thin coating; fifth, to providein combination with such glue container a spreading attachment for distributing and levelling the adhesive material discharged from the container when inuse; sixth, to provide a device wherein theamount'of efliuentissuing from the container .iscontrolledby the amount of the openingbetween the spreading attachment and the outlet of the container; seventh, to provide a device .witha manual control over the combined operations of discharging and spreading the liquid adhesive; eighth, to provide a device wherein the amount of effluent is also regulable by a positive stop I which may be adjusted and permanently set in various positions to permit desirable amount of opening between the spreading attach- ;ment and the outlet of the container; ninth, to

provide a devicewherein the spreading attachment automatically seals the outlet of the liquid container when the. device is not being used; and

lastly to provide as a whole a novelly constructed glue containing and distributing device which is particularly simple, durable and economical of construction, requiring a minimum amount of maintenance, and one which will not permit its contents to become oxidized or dried when not in use, ,to spill or overflow when upset in any way, to become diluted to a point beyond use when the device might be immersed in a body of water whichis customary practice among oper ators when the device is not being used.

These and other objects of my invention con- 1 sisting of novel features of construction, comthat part of the specification following wherein the features are described in detail and will be more clearly understood by reference to the attached drawing in which:

Fig. 1 is a side elevational view of the improved glue container and spreader tiltedback in the position which it would assume when not in use and left standing on a horizontal surface.

Fig. 2 is a sectional view in elevation of the device clearly showing the opening between the roller and spout of the glue pot as the apparatus is drawn over the surface being treated.

Fig. 3 is a front elevational view of the device.

Referring to the drawing, No 1 indicates the container which is a hollow aluminum casting having a handle 2 suitably joined to and spaced from the container I by a plurality of posts 3. The adhesive materials are charged into the receptacle through circular opening 4 which is covered by cap 5 and held tightly in place over opening 4 by means of a spring 6 which projects into the posts 3 under shoulders I. The liquid adhesive pours through the opening 8 out of spout 9 when the roller II is separated from the concave seat of spout 9 of the container I. The curvature of this seat is such as to provide a snugly fitting seat for the roller when the two are in contact with each other, An integral foot I0 is shown as a part of the aluminum casting comp-rising the container and is located between the middle and spout-end of the base so that when the device is placedon a horizontal surface it tilts backward permitting the sealing ofthe spout 9 by means of roller II under pressure of springv 26 after release of pressure on griplever 23.

Roller I 'I is preferably made of rubber and journaled on a rod I2 extending between side arms I3 and I3 of an aluminum casting I5. Side arms I3 and I3 constituting the ears of the aluminum casting I5 are pivoted on their respective sides to the hollow aluminum receptacle by screws or trunnions I4 and I4. ing I5 is pivoted and joined by means of pin I6 to collar I? which is drilled and threaded to receive the threaded end of rod I8.

Rod I8 which controls the movement of the aluminum casting I5 and serially in turn that of the side arms I3 and I3 and ultimately the movement of roller I I to and from spout 9, extends upwards through a jaw-like piece I9 which is an' extension of handle 2, passing therethrough to be joined by pin 2| to the extension 29 of. grip lever'23 which operates as a lever about the fulcrum and pivot pin 22. On the upper end. of this Aluminum cast- 7 rod [8 are the parts which regulate the adjustment and set the stop, which in turn controls the amount of opening between the rubber roller II and spout 9 when the device is in use. These consist of a lock nut 24 for holding the adjusting nut 25 in a set position. The adjusting nut 25 carries a sleeve 2'! which houses the spring 26. Sleeve 21 moves with the adjusting nut 25 as an integral part thereof and may or maynot contact washer 28 depending on the. setting .of the adjusting nut 25, while the spring 26 constantly bears against washer 28 regardless of the position of the adjusting nut.

In preparing this glue container and spreader for use the cap 5 is removed and adhesive material is charged into receptacle l through opening 4. After filling the container the cap is sprung into place and securely fastened over'the opening by spring 6, the extensions of which fit grippingly under the shoulders.l'l of posts 3-3. The next preparatory step is the determination of the size of opening that will be requiredbetween roller H and spout 9. This depends upon the viscosity and general characteristics of the adhesive material employed and also on thethickness of the application of same that the operator desires to spread on the surface-to be-treated.

Bysetting adjusting nut 25 the free movement of. rod I 3 is limited which limited motion is translated through several movable parts to the roller l l which in turn is only allowed alimited recession from spout 9. All the aforementioned movable parts are controlled and set in motion by the movement of the lever arm 2,3 in -the grip of the operator. Thus when the adjusting nut is secured by means of locknut '24 at a low point on rod. l8 there will be arelatively wide recession of the roller from the spout under the full movement of lever .20 23. By depressing-handle 23 'to the limit rod.l8 will rise throughjaw-like. opening l9 until sleeve 21 strikes washer 28. In rising rod .l 8 will lift crosspiece'l5 and in turn swing roller I l away from spout 9. On the other handif the adjusting nut is set higher up on rod l8 the recessionof the roller from the spout will be proportionately less. It will b apparent to-those skilled in theuse of mechanisms of this type thatthe recessionof the roller from the spout is proportional to the distance between the edge ofthe sleeve 21, which is an integral part of the adjusting nut, and the washer 28, if theoperator grips the handle 2 so as to continuously depress lever 23 to the limit during use.

The fine screw adjustment of the amount of opening between the spreading roller and the spout of the container is a special featureof the invention. The operator is instructed t0 r the handle of the device firmly in such a-manner that the lever arm .23 is depressed to the limit. The

simplicity of construction and operation of the glue spreader is such that aside from the above instruction the operator is not called upon to exer- 1cise any judgment as tothe amount of glue he deposits on the surface being treated or the manner he should spread the deposited material about the surface. By merely pulling the device lightly across the surface auniform amount ofadhesive, predetermined by the setting of the fine screw adjustment, will be automatically deposited from the open spout, and spread by the rubber roller, along the entire lengthof the surface treated or, onas many surfaces desired, as long as the container holds a supply of adhesive, By reason of this automatic regulationof discharge and spreading of glue most of the human error usually to be reckoned with among operators in shipping and wrapping departments is avoided, permitting more time for better and more uniform applications and sealing of packages.

The container itself is a distinct improvement over many such on the market used for similar purposes in that so long as it contains adhesive material it is always ready for use on any type of glue-coating work. The aluminum casting comprising the receptacle has only a circular charging port on top and the outlet spout along ,-.the lower front edge as openings for the possible loss of material or introduction of air or water. These openings are securely closed respectively by the cap which is sprung over the charging port and held in place by the spring, and the rubber roller which is held fast on the seat of the spout by the spring'26 after the operator releases his grip on the handle 2 and lever 23. Thus sealed up in the practically air tight receptacle the adhesive material will not be exposed to the drying or hardening influence of air nor will it absorb or becomediluted with water when immersed in a body of waterwhen not inuse. Likewise any accidental loss of control over the apparatus will not result in a discharge of its contents about the premises. Lastly the prompt sealing of the spout upon the operators release of pressure on the grip-lever, although still holding'the device aloft; prevents the objectionable dripping of adhesive material over the packages, work bench and-floor in the vicinity of the operator. 7

As described this disclosure relates to a portable manually operated glue container and spreader but-it is also within the scope of the invention to usethis device for distributing any type of adhesive material that will flow through-the elongated narrow opening-in-the spout. Also-the device-disclosed may be advantageously-made an integral part of a machine operated glue applicator.
