JAMES IL' PORTER, OF HARTFORD, CONNECTICUT.

MUCILAGE HOLDER AND SPREADER.

SPECIFICATION forming part of Letters Patent No. 449,233, dated March 31, 1891.

Application filed September 19,1890. $erial No. 365,512- (No model.)

To all whom it may concern.-

Be it known that I, JAMES H. PORTER, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Mucilage or Paste Pencils, of which the following is a full, clear, and exact specification.

The invention relates to the class of articles which hold an adherent, as mucilage or paste, in a condition to be applied to the surface of a piece of material that is to be secured to another piece of material.

The object of the invention is to provide a simple, cheap, and portable article of this class which is always ready for use, will not gum and harden so as to become unserviceable, will not allow the adherent to leak out when carried in the pocket, and which will distribute the adherent more evenly and neatly than prior similar articles.

Referring to the accompanying drawings, Figure 1 is a perspective view illustrating the use of the pencil. Fig. 2 is a central longitudinal section. Fig. 3 is a detail enlarged transverse section of the roll. Fig.4 is a detail side View of a modified form of roll.

In the views, the letter a indicates the body of the pencil, which may be made of metal, wood, paper, celluloid, glass, or any similar material, drawn, out, rolled, molded, or otherwise formed into a tube of round or square cross-section, having thin walls. The sides of the tube at one end are drawn to form a square or rectangular opening,in which a cylindrical roll I) is fitted and held by the pivot c, which passes through the walls of the tube near the end, so that the roll can freely revolve in the opening, with a portion projecting into and a portion projecting out of the tube. This roll is preferably made of rubber, but of course can be formedof wood, paper, celluloid, or any other similar substance of comparatively firm texture, of a size that closely fills the opening in the end of the tube, and its surface is provided with a series of closed pockets d, which are formed by cutting longitudinal or spiral radial slits in the l periphery either for the entire length or only a portion of the length of the roll. Upon or into the end of the tube opposite from the roll is placed a cap or stopper 6, which may be removed for filling the tube with the adherent mixture or for cleaning, and a cap f, which slips over the opposite end, is provided to protect the roll from dust and dirt. The cap 6 has, preferably, a projecting edge, which is milled or knurled to facilitate its removal, while, if desired, the cap f may have a squared portion or flange, as shown in dotted outline in Fig. 2, so the pencil will not roll when placed upon its side.

WVhen the tube is filled with mucilage or paste, the portion of the roll which is in the interior of the tube is smeared with the adherent, and when drawn across a surface which is to be fastened the roll revolves and leaves a smooth even film of compound in its track. The edges of the roll so fit the opening in the end of the tube that none of the compound can leak out, and the little slits with which the roll is provided convey just the right quantity of the adhering compound from the end of the tube and deposit itupon the surface to be fastened, where it is spread evenly by the periphery of the roll. This roll deposits the adhering compound in a thin continuous even film in a path with straight edges, and does not sometimes leave a large quantity in a wide strip and sometimes a small quantity in a narrow strip, depending upon the pressure applied; nor is it inclined to spatter the liquid, as is the case with prior articles employing a brush, sponge, or stopper held in place by a light spring, for depositing mucilage or paste, and the roll does not become saturated and harden so as to become unfit for use. These little slits, however, render the roll somewhat brush-like and more flexible, and convey a small quantity of the adhering material, and in their normal condition are closed together, so that the periphery of the roll is smooth and completely fills the opening in the end of the tube, but when pressure is applied allow the roll to flatten, so that it may be rotated, if

gummed, and to deposit what adhering mateslits being normally in contact, whereby the rial is in the slits. periphery of the roll is smooth, substantially 10 I claim as my inventionas specified. As a new article of manufacture, a pencil 5 for adhesive compounds, consisting of a tube with one end closed by a roll formed of a Witnesses:
