QEORGE I. METZ, OF YONKERS, NEW YORK METHOD OF COATING Application filed December 22,1928, Serial No. 327,855.

My present invention relates to an imteristic pencil to which the coating may be I provement in the method of covering devices applied.

In some respects the improvement herein It w1ll e understood that, while I have is analogous to my improvement in process of herein disclosed and described pencils and coating articles of manufacture as described yhndrlp l dsvlces as Objects to be Coated,

The edges 6 )e "apprehended as the herein description andzare scarfedr.ang1ed P to q )roceeds, and it is obvious that modifications ggfiggzfi -z gfi ig igg fii g S it if the herein descrlbed method and article bein ag g s h l nay be made without departing from the to gn g z g gi 0 plnttflhereof or of t The length B of the sheet 5 is of suflicient accompanymg w pgsd1mension to suit the longitudinal exterior e is sheet of costlng 111 surface of the article being coated, as. at C, rs pec 1ve..

i 45 Thereafter 10 shown in Figs. 2, 4 and 5.

After softening of the sheet has been accomplished the device may be laid upon the flat softened sheet and, where the object or device to be covered is cylindrical as in Fig. 5 is rolled around and about the cylindrical surface and encompasses the surface of'the barrel, as indicated by the dotted lines'8, Fig.- 3, and the scarfed edges 6 and 7 are touched along their scarfed faces with 0 a suitable celluloid cement which perm anently locks the quill 8 upon the barrel 2. Owing to the softening effect of the alcohol upon the sheet 5 prior to rolling, the sheet expands slightly in all of its dimensions so sheet 5 is blanked and scarfed, as above described, due allowance must be made for the expansion by making the blank slightly smaller than is actually required, sothat when rolled about the barrel 3o 2, the scarfed edges will match perfectly as at 6 and 7, Figs. 4 and 5, and be in reasonable mechanical engagement with the surface 2.

, The article thus coated is then laid aside and as the alcohol gradually evaporates from the celluloid becomes hardened to its original form and at the same time shrinks slightl and thereby causes the quill to become tig tly wrapped about and engaged with the surface 2 of the article 1 in 4 firm engagement therewith, so that the quill thus formed thereon cannot be normally withdrawn or removed. Thus, the shrinkage causes the quill to become firmly adhered to the surface of the article being covered.

should there be any visual indication of ine ualities of the sheet along the cemented" line ormed by the jointure of the edges 6 and 7, as indicated by the dotted line 9, .Fig. 4-, the longitudinal seam thereby so formed may be polished or bufl'ed away, thus leaving the coating without any obvious line of demarcation and substantially smooth on its exterior.

Owing to the pliability of the softened .55 sheet, as above described, it is obvious that a large number of articles may be coated where it ispossible .to aflix a single sheet thereabout, as herein described, andthat the subsequent shrinking thereof, during dryingand hard- .60 ening of the softened shell, causes the sheet 7 or shell'to become firmly adhered to the body of the article or device to which it is aflixed. Its also obvious that porous or absorbent bodies may also be so covered, such as plain and that the shrinkage of the coating thereon, after application, will cause firm adherence to the body to which the shell is so afiixed without the use of any cement other than the cementing of the joints of the covering ma terial used.

It is also obvious, by this particular means, that highly ornamental effects may be obtained in a simple and inexpensive manner, upon devices of this sort. Forinstance, the barrel 2 of the pencil may be of any single color, such as blue, black or brown which, of itself has no highly ornamental effect, but the covering material thereover may be transparent, translucent or in imitation of semitransparent mother -of pearl.

Thereafter, when the covering material is wrapped about the article to be covered, as

herein described, the eifect of the under color of the body 1, showing through the trans-.

parent, translucent or semi-transparent mother of pearl coating, greatly adds to the decorative. finish thereof which finish may thereafter be highly polished and makes a very effective and attractive covering.

It will be noted that the scarfing of the meeting edges 6 and 7 of the quill forming shell 5 is substantially in the form'of an overlap due to the scarfing angle and when these two edges are properly cemented together, especially on material that is extremely thin, it increases the cementing surface of the edges, as noted, and forms an overlapped seam of great strength and sulficient to resist the shrinking tensionv of the rshell when it is dried and hardened upon the article aboutwhich it is wrapped.

What I claim is:

The method of covering parts of an article with a coating sheet,'which consists in forming a sheet of celluloid, having substantially the same length as the part of the article to be covered therewith anda width substantiallye ual to the periphery of the said part, then so ening the sheet, then wrapping the said sheet about the said part with the longitudinal elements of the sheet positioned parallel to the length of the said part, thereby causing the lon 'tudinal edges of the sheet to meet each ot er'in a line which is substantially parallel to the length of said part th'en cementing the edges of the coating sheet to each other and thereupon permitting the said coating to harden and shrink on to'th( said part.
