J. JOHNSON ADHESIVE APPLICMORr 2 Sheets-Sheet 2 Filed `June 2 8, 1955 ERL E www 0 s r N r H 4 m6 M H 2 United States Patent O 2,789,729 ADHESIVE APPLICATOR John Johnson, San Francisco, Calif. Application June 28, 1955, Serial No. 518,444 2 Claims. (Cl. 222-107) The present invention relates to improvements in an yadhesive applicator, particularly for the purpose of rmly cementing the butt of a composition shingle to a shingle beneath it, wherein a tube of a thin, exible, impervious material formed from an envelope of Celluloid, cellophane, or the like, has fashioned thereon a comparatively at, exible, reenforced nozzle, adapted to be inserted into a restricted space under the butt of a shingle, previously pried up and held by a spatula or putty knife or the like to facilitate introduction and extrusion of an asphaltic adhesive under said butt, when said spatula is removed and said butt pressed flatly upon said nozzle.
The primary object of the present invention is to provide a new and improved adhesive applicator having improved means adapted to extrude an asphaltic adhesive under a close lying butt of a composition shingle, or the like.
Another object is to provide a new and improved applicator of the character set forth, having an improved dispensing nozzle adapted to extrude an adhesive and to be sealed against inadvertent extrusion of the same when flatly compressed.
A further object is to provide a new and improved applicator of the type described having a greatly simplified and economically produced and substantially reenforced nozzle and a maximum eiiiciency.
A further object is to provide a new and improved adhesive dispensing tube fashioned from a flat rectangular envelope of thin, flexible, impervious material, such as Celluloid, cellophane, or the like, having a reduced, comparatively flat nozzle adapted to extrude a plastic adhesive, and to be temporarily sealed by compression.
The improvement comprises the device disclosed in the drawings forming a part of the present application, and in which- Figure 1 is a partly broken elevation of a at envelope of thin, flexible impervious material, from which a dispensing tube may be formed;
Figure 2 is a plan View showing the first step in the formation of a tube and flat dispensing nozzle;
Figure 3 is an elevation of a completed tube, containing an adhesive to be dispensed;
Figure 4 is `an end elevation of a completed tube and nozzle;
Figure 5 is a plan view of an applicator kit, with tube and coordinating spatula therein;
Figure 6 is a broken schematic view disclosing the dispensing nozzle inserted, with the aid of a spatula, beneath a butt of -a fixed shingle;
Figure 7 is a similar view, disclosing the nozzle being compressed by a shingle butt and adhesive extruded therefrom by said compression; and
Figure S is an enlarged, schematic view of a typical cross-section of the nozzle, disclosing the manner in which the same is reenforced on opposite flat sides thereof.
Referring to the drawings, the numeral 2 is used to designate in general a preferably flat, thin, flexible Celluloid or cellophane envelope having one end closed by folding over and sealing one end, as at 4.
A comparatively flat, reenforced dispensing nozzle 6 is fashioned or formed by folding preferably one over and one under, parallel opposite lateral sides 8 upon a central longitudinal portion 10, of similar width as said lateral sides 8, as disclosed in Figure 2 of the drawings,
whereby opposite comparatively flat sides of a nozzle 6 are substantially strengthened by mutiple layers, as schematically disclosed in Figure 8. An annular collar 12, of the same liexible, impervious material, may be wrapped around the nozzle 6, as disclosed in Fig. 4, to further reenforce the nozzle 6.
The tube 14 thus formed is lled preferably with an asphaltic cement or adhesive, as being the most suitable and substantial for cementing the butts 22 of a composition shingle firmly onto a lower shingle 24 below it. The tube 14 is then closed at the end opposite thek nozzle 6 be folding over and cementing said opposite end as at 11.
To further facilitate the cementing of a butt 22 to the surface of a shingle 24 beneath, a suitable kit may be provided which comprises a suitable container 16 within which is contained a filled tube 14, and a preferably rigid spatula, such as a putty knife 18, the purpose of which hereinafter more fully will be described.
In operation, in order to prevent laceration of the linger tip and nails of an operator in prying upwardly a number of shingle butts, the spatula 18 is inserted under the lower edge of a ixed butt 22 and by said spatula pried upwardly and held to provide sufficient space to facilitate insertion of the at nozzle 6, as disclosed in Figure 6. After which, the spatula 18 is withdrawn and used to press said butt 22 rmly downward to compress said nozzle 6 and thereby extrude a portion of adhesive 26 between said butt 22 and lower shingle 24. As the tube 14 and nozzle 6 thereon are withdrawn, the pressure of the butt 22 thereon will extrude adhesive and also spread the same uniformly between said butt 22 and shingle 24 below, and also simultaneously exhaust said nozzle 6 and by pressing the opposite internal at walls of said nozzle together, effectively seal said nozzle, temporarily against any inadvertent extrusion of cementl 26.
It should be particularly noticed, by reference to Figure 8, that the formation of a comparatively flat nozzle fashioned by folding over and under opposite lateral sides of the comparatively frail envelope 2, that a triple layer of said thin material is provided upon opposite sides of said nozzle which are subjected to compression and friction, so that the said nozzle 6 repeatedly may be withdrawn under pressure without undue wear, and more particularly when further enhanced by the encircling annular collar 12, whereby a durable nozzle may be fashioned from a thin, flexible material.
Having described my invention, I claim:
l. An adhesive applicator comprising a tube formed from a at envelope of thin, flexible impervious material and having a closed end and a comparatively flat nozzle fashioned on said end by folding equal lateral portions of said closed end upon a central longitudinal portion of equal width with said lateral portions, said nozzle being adapted, when cut, to extrude a flat plastic adhesive therefrom and to seal said nozzle when the same is atly compressed.
2. An adhesive dispenser comprising a tube formed from a flat envelope of thin, flexible, impervious material having a closed end and a comparatively at reenforced nozzle with a closed end formed thereon by folding opposite sides of said closed end atly upon a central longitudinal portion of said envelope, said nozzle being adapted, when said closed end thereof is cut therefrom, to extrude an adhesive from said nozzle and to seal the same, when said nozzle is flatly compressed.
