The present invention relates to a novel accessory in the nature of an attachment for the neck 'of a mucilage or liquid glue bottle or container, and the purpose of the device is to provide a reliable and conveniently usable glue dispensing applicatorwhich is in effect a dispensing cap and spreader brush.

Under present prevailing circumstances, We find users of liquid glue attempting to apply it with precision to limited areas on Wood and other connectible parts and surfaces by various makeshift instruments. Some use match stems, sticks of wood, and all sorts of haphazard instruments. Many resort to the use of the customary bristle brush which is generally supplied with glue bottles and similar containers. I have discovered the need for the adoption and use of a more satisfactory applying and spreading brush. Thus, as before indicated, it is my primary objective to provide an attachment which can be applied to conventional bottles and which is expressly made, primarily of rubber, to function with a requisite degree of nicety in applying glue accurately.

In keeping with the expected requirements for an applicator possessed of simplicity and efficiency, I have found it expedient and practicable to adopt an attachment characterized by a pouch-like receiver, this being detachably connectible with the discharge neck of the glue can,

and having its discharge end fashioned to form a double lip controllable mouth through which the glue may be fed, according to prescribed conditions, and thereafter spread smoothly on the desired area of the work being acted on.

Furthermore, in accordance with the, dictates of my present judgment as to what constitutes an appropriate adaptation in this particular line of endeavor, I have perfected the aforementioned pouch-type applicator, an outstanding feature of 4,0 which is a properly reinforced discharge mouth forming the spreader, this having located therein hand controlled regulating means to restrict the size of the mouth and to thereby limit the glue delivered for use.

Other features and advantages will become more readily apparent from the following description and drawings.

In the drawings, wherein like numerals are employed to designate like parts:

Figure 1 is an elevational View of a conventional can of glue showing the spreader attachment in place and in readiness for use.

Figure 2 is a side elevational view of the spreader attachment per se.

Figure 3 is an enlarged bottom plan view of said attachment detailing with requisite precision the valved discharge mouth and double lip applicator means or construction.

Figure 7 is a perspective view of the valving or regulator element.

Figures 8, 9 and 10 are perspective views of certain complemental details.

Figure 11 is an exaggerated detail section on the line ilii of Figure 2.

In Figure 1, a conventional mucilage or glue containing can or equivalent container is denoted by the numeral l2. this being provided with the customary screw-threaded discharge neck it. The spreader cap or attachment is indicated, as a unit. by the numeral M. This is of general dovetailed-shaped outline or configuration. Obviously, however, it may be of any appropriate shape to properly dispense and spread the liquid glue in a desired ribbon-like stream. so that it may thereafter be spread along the desired surface (not shown). As before indicated, the bOdV portion of this attachment or device I4 is in the nature of a receiving hopper or pouch which contains a quantity of the glue when the can is turned upside down, as shown in Figure 1. When the mouth of the pouch is completely open the glue runs freely therefrom onto the surface be 35 ing prepared for jointing. In fashioning this pouch-like receiver I have found it practical to utilize a pair of duplicate sheets of rubber or equivalent members of the general configuration shown in Figure 8 and denoted by the numerals Hi. The numerals l6 designate slits which serve a purpose to be hereinafter described. The converging meeting edge portions of the two rubber sheets are molded, glued, or otherwise connected 5 together to define the pouch-like receiver. In Figure 6 the adhesive cement or other agent is indicated at H. The truncated or apex ends Hi are detached, and at this point a rubber collar is is cemented or otherwise secured in place. 50 This forms a substantially round mouth which snaps over the discharge neck l3 of the can, as shown in Figure 1. The numerals 29 merely designate a metal stay or reinforcing strip to prevent over spreading of the pouch whereby to main- 55 tain it against distortion and subsequent bursting.

Attention is next called to the discharge mouth denoted by the numeral 2|. This is of longitudinally elongated form, and the stream of glue can obviously be allowed to gravitate therethrough onto the wood or other surface being conditioned for jointing. This mouth is formed by placing rubber spacing blocks 22 and 23 between the opposed flaps or lips 24, as brought out to advantage in Figures 3, 4, and 6. The blocks 22 and 23 are cemented or glued or otherwise secured in place. They therefore maintain the lips or spreading flaps 24 in parallelism. As shown in Figure 6, the numeral 25 designates a regulator which is in efiect a valving element. This comprises a band of rubber 26 anchored at one end on the spacing block 23. The opposite end is wrapped or wound around an adjusting bolt, that is, the shank portion of the bolt is indicated at 2?. In accomplishing this, the free end of the rubber band is wrapped as at 28 around the shank 2'! and is provided with a reinforcing insert as at 29. Of course, the rubber could be thickened at this end and accomplish the same result. The main idea is to render the free end of the band sufliciently rigid to permit it to be attached to the adjustable bolt 2'! in a reliable manner. The bolt has its threaded end provided with a clamping nut 30. The numerals 3i designate washers.

The bolt 2i extends through the aforementioned slits I6 and then through slots 32 provided in opposed duplicate metal cleats or strips 33. These metal strips are bolted to the spacing blocks 24, as indicated by the fastening bolt 34. The main fastening means for-the strip, however, comprises a wire rivet 35 imbedded in the rubber, as indicated to advantage in Figure '7. These riveted metal plates or cleats serve to properly shape the discharge mouth 2|, that is, they hold the rubber flaps 24 substantially rigid and in parallelism. Moreover, the slots 32 in said metal strips serve to accommodate the bolt 21 allowing it to be slid back and forth to stretch the rubber bandZfi and to fasten it in a set position. In Figure 3 we see the rubber band or valving element 25 substantially in its open position. Thus, the left hand end of the mouth 2! is partially closed. It is possible, however, to stretch this band from left to right in Figure 3 and restrict the length of the mouth 2i, then tighten the nut 38 to maintain this adjusted discharge opening.

The gist of the invention is in the provision of the rubber double walled pouch l4 serving as an attachment and receiver for the discharge neck of a glue can or equivalent container. The pouch has its discharge end fashioned with spreading lips or flaps 24, these being associated with the discharge mouth 2! in which the valving means 25 is located to regulate the size of the mouth and to thereby regulate the dispensing of glue. The metal strips 33 are important in that they serve as reinforcing elements in conjunction with the stay strip 28. They also serve to facilitate proper adjustable mounting of the valving element 25 and, it will be noted'that the lips 24 extend beyond the so-called lower edges of these two metal strips so that the metal strips serve as backing elements allowing the flaps to press thereagainst and to prevent undue spreading and flexing of said applicator flaps or lips 24.

It is obvious that when the device is attached to the can and the can is turned upside down, the glue runs into the pouch and then discharges through the delivery mouth 2|. It can then be conveniently spread by the brushing or rubbing action of the flexible flaps or lips 24.

It is thought that the description taken in connection with the drawings will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.
