COMPOUND STAY FOR PAPER BOXES.
. Specification of Letters Patent.
Application filed October 20, 1910. Serial No. 588,199:
To all whom it may concern Be it known that I, WILLIAM G. CHAPIN, a citizen of the United States, residing at Brooklyn, in the county of Queens and State of New York, have lnvented certain new and useful Improvements in Compound Stays for Paper Boxes, of which the following is a specification.
The immediate object of this invention is to provide an effective, serviceable, and reasonably cheap form of tape for use in joining' and staying the abutting, or adjacent, edges or corners of paper boxes,'box boards, and the like articles, and my said invention consists primarily ofa tape formed of a plurality of superimposed strips, of different widths and preferably of different relative strength, as I shall explain in detail hereinafter.
The annexed drawings aid in explaining said invention, Figure 1 being a perspective view of a box having its adjacent corners and bottom edges secured fixedly in proper relation to each other by tapes embodying my present improvement. Fig. 2 is an enlarged, perspective,- view of one corner of such a box, the outer staying tape being turned back to disclose the location of the relatively smaller under tape. Fig. 3 is a perspective view of a roll of my improved compound tape showing the end portions of the two tapes separated for a bettervunderstanding of the construction of the said compound tape.
My said tape is particularly convenient and valuable for joining the edges of that class of boxes in which the ends, sides and bottoms (or tops) are formed of independently cut sections, as distinguished from that class of boxes in which the ends, sides and bottoms or tops (as the case may be) are formed of a single piece of board that is scored and bent along the lines which define ahe outline, size and shape of the finished In the construction of boxes from expensive boards, such as corrugated or so-called cellular board, it is desirable, as a matter of economy, to cut the box sections independently and it is also desirable, in fact necessary, that the adjacent edges of such sections shall be so securely joined that they cannot be readily separated by tearing, moistening, or otherwise, and my resent improved form of tape is special y valuable and effective in such instances, as I have already stated. It is also specially valuable for sealing folding boxes and cartons so they cannot be tampered-with while they are in transit.
Briefly described, my said invention consists in iproviding a tape formed of a plurality 0 strips, the inner or under one of said strips being preferably of cloth or tough paper and the outer one of said strips being preferably .of paper and somewhat wider than the under strip, thus providing a cover strip which effectually hides and protects the under strip, which latter serves as the stay proper although the relatively wider cover strip supplements the staying gualities of the under strip in a considerable egree.
In the accompanying drawings the reference letters a indicate the sides and b the ends of a box. In setting up a box of such a type the ends and sides are placed in proper relation to each other and the abutting edges are fastened together by a narrow tape 0 which is preferably a strip of cloth or tough paper; the said tape a being firmly attached to the box section by means of glue or other suitable adhesive.

tective or cover strip (1 is then applied, over the stay strip 0, and it may be stuck to the said stay as well as to the box blanks which its edge portions overlap, or may be securely stuck to the box or preferably only to the edges of the narrower stay. I find in practice that when my said compound tape is used on flat surfaces it is quite feasible to unite the two or more strips by gluing their entire engaging surfaces together but, when curves it is advisable to glue the edge portions only of the narrow stay to the wider cover strip thus leaving the mid-portion of the cover strip disconnected from the stay, and therefore free to stretch slightly, or otherwise adjust itself when wrapped around corners. If preferred, the stay'strip 0 and the cover strip amay be glued, or otherwise stuck together, before the stay strip is applied to the box; in fact, I prefer to unite the strips 0 and d before they are applied to the box and Imay supply the same in rolls of considerable length, as seen in Fig. 3. The compound stay thus provided may then be cut into predetermined lengths and applied to the box sections, or
said tape is to be applied around corners or i are it may be applied first and then cut and dctached from the roll. When thus furnished in rolls the strips are gummed on their faces that are to engage the box bpards, so that it is only necessary to moisten the said guinmed face and then apply the tape to the set-up box.
While I have thus far specified a compound tape made up of two strips I wish it understood that I may provide more than two, for use in instances where unusual strength and protection are desired.
In building up the compound tape I may use cloth for the under strip or stay proper, and. paper for the outer or protective strip or strips, While in other instances I may form both the stay and cover of paper.
One of the important advantages resulting from the use of the cover strip 03 is in the fact that said strip effectually checks, and prevents the escape of, the adhesive on the stay strip, if said adhesive is inclined to ooze through the said stay, which sometimes happens when coarsely woven cloth is used.
As a means of protection against tampering with a package sealed with my described stay, the outer strip may be watermarked, or otherwise made with some distinctive feature that cannot be readily im itated; thus making it practically impossible to remove the strips and replace the outer or cover strip with a counterfeited ed to adhere to the materials on each side of a joint.
