LIQUID-APPLYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 764,796, dated July 12, 1904.

Application filed July 3, 1903. Serial No. 164,284. (No model.)

To all whom it may concern:

Be it known that I, LEVI WALTER DAvIs, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Liquid-Applying Apparatus, of which the following is a specification.

My invention relates particularly to improvements in that class of devices known as gummers, paste-appliers, mucilage-distributers, and the like; and its object is to provide a convenient and economical device of the class described suitable in its scope, which ranges from a small label to a length of wallpaper.

Another object in view is to evenly coat the entire surface of the applied material without waste of the liquid, also for the rapid manipulation of material, the cleanly manner of the said application, as well as the convenience thereof, and to provide a reservoir which is susceptible of ready transportation. The reservoir is adapted to be readily cleansed, while at the same time it is so arranged as to practically prevent evaporation of its contents.

I attain these objects by simple devices hereinafter fully described, and shown in the accompanying drawings, in which Figure 1 is a perspective View of the apparatus; Fig. 2, a section on line a b of Fig. 1, showing the interior arrangement; Fig. 3, the plan of a fragment of the hinged cover, and Fig. 4 the end elevation of the same.

In the drawings, 1 1 represent the rectangular ends of a thin metallic case, the lower edges of which rest upon the table, bench, or floor upon which the apparatus is placed. The upper edges 2 2 extend above the level of the top surface, forming guiding-flanges for the strips of material passed over the roller in the process of receiving a coat of the liquid. The bottom of the case 3 is preferably made cylindrically concave, so that the liquid contained therein shall be deepest in the center, and that form obviously permits use to be made of the liquid so long as any shall remain within the case. The sides I iand half-top 5, together with the bottom 3, are preferably made of one piece without joint, formed into the proper shape and united to the ends 1 1 by solder. The other top, 6, is made separate and united to the side 4 by a hinge-joint extending its entire length. The inner edges of both top pieces are bent downwardly in conformity with the radius of the roll 8 and are arranged to barely clear its periphery when the said roll is resting in its bearings 7 7 which are V- shaped, open at the top, and of suflicient angle to allow the roll to be withdrawn. The bearings 7 7 have outwardly-extending arms secured to the ends 1 1 and also half-top 5. The hinged top 6 normally rests on the opposite arm, but is readily removable therefrom. The roll is a hollow cylinder having projecting pintles 9 9 at both ends adapted to rest and revolve in the open bearings 7 7 It is desirable that the roll 8 be made light enough to float in the liquid contained in the reservoir, as by so doing it will rise in its open bearings, fill the opening at the top between the covers, and hence prevent evaporation of the liquid in the reservoir. The thin film of liquid which may be upon the surface of the roll after use materially aids in forming an air-tight joint in the manner ofa packing.

In operation the cover is turned back, the reservoir formed in the case filled with the liquid to be applied, the cover replaced, and as the periphery of the roll is always slightly above the otherwise smooth surface of the top the friction of the article moved over the top causes it to revolve and deposit an even film of the fluid, in which the roll is semisurrounded on the lower surface of the article. So long as any liquid remains in the reservoir this action will be continued. It is not necessary to remove the remainder of the liquid after use, as the case, in combination with the roll, forms a sealed receptacle for its maintenance; but if for any reason it becomes desirable to change the contents or cleanse the reservoir it is readily accomplished by turning up the top and withdrawing the roll.

While this apparatus is specially designed for gumming labels, applying liquid paste to wall-paper, blanks, and like uses, it is evident that it may be used with equal readiness in applying any liquid or semiliquid prepation.

Now, having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a liquid-applying apparatus, a buoyant roll, situated partially within a reservoir and adapted to be revolved by the superficial contact of material passed over its exposed periphery, of continuous flanges, depending from each side of the opening in the cover of the said reservoir, forming in connection with the longitudinal side Walls of the said roll, a normally non-evaporative chamber below, all substantially as shown and described.

2. In a liquid-applying apparatus, the combination of a case containing a reservoir provided with a hinged cover or covers having a longitudinal central opening, of a distributing-roll loosely journaled within said case; of downwardly-extending flanges, integral with the covers, contiguous to and on each side of the said roll and of upwardly-projecting end walls forming guides, all substantially as and for the purposes set forth.

3. In a liquid-applying apparatus, the combination of aself-sealing reservoir, of a hinged cover or covers, of a distributing-roll, and of guide-walls above the roll-surface.

4:. A liquid-applying apparatus comprising a case, a cover in two parts, either or both hinged to the side walls, journal-hangers attached permanently at each end and inside the case, afloating cylindrical roll, provided with pintles at each end and adapted to rest and revolve in said hangers when depressed, and having a portion of its periphery slightly above the surface of the covers, and guidewalls at each end of the apparatus, all substantially as and for the purposes as set forth.

In testimony whereof I affix my signature in presence of two witnesses. I

LEVI WALTER DAVIS. Witnesses:
