Nov 9, 1937. E. H. ANGIER 2093909 BOX STAY Filed Aug. 8, 1955 Patented Nov. 9, 1937 UNITED STATES PATENT OFFICE BOX STAY Edward H. Angler, Framinglum, Maas. ankam to Edward H. Angler, Framingluni, Mnss., u
This invention relates to reinforced strips for use as box stays or the like, and the object is to provide an improved stay strip for adhesive connection to a box of fiber-board o1 similar material to joln er reinforce the joint between opposed edges er other parts of the box. The construction and advantages arising therefrom will be well understood by those skilled in the art by reference to the following description of an illustrative embodiment thereof shown by way of example in the accompanying drawing, wherein:
Fix. l is a perspective vlew of a box having a form of stay illustrative of my invention applied thereto; and
Fig. 2 is a fragmentary plan view of a portion of the stay strip with parts broken away.
In Fig. 1 of the drawing I have shown the box 5 havlng an edge thereof where the ends of the blank join secured by a stay I embodying my invention and have also shown the stay I securing together the cover flaps 9 and extending down the sides of the box in the customary manner. The stay strip I, as best seen in Fig. 2
is in the form of a narrowband which may be provided with a gum coating II which may be moistened to secure the stay in position on the box, the band herein conslsting cf two strips I3 and I5 of kraft er like streng paper, which bands are united by intervening waterproof adhesive, such as black aphalt I'I. Incorporated with the base strip paper stock, herein by being embedded in the a'sphalt I'I, is a strand-like reinforcement, herein shown as consisting of a single continuous yarn I9 of cotton, jute er the like. 'Ihis reinforcement 1s here shown as extending across the central portion of the band where the jolnt of the box would occur, across substantially the entlre width thereof, yet received as a whole within the longitudinal ends of the band, and may be zigzagged back and forth as shown to provide diagonally disposed parts relatively closely adjacent one to another and which make substantially great angles with the length of the strip. That is preferably, while generally diagonal, the separate sectlons of the zigzag curve are more nearly transverse than longitudinal. The reinforcement I9 is substantially single, that is to say, als least in the central portion of the band there are no interweaving er crossings formlng a retlculation, but on the contrary the relnforcement is the single thickness of strand, although lt will be understood that a plurality of strands might be applied side by side and handled substantiaily as one.
Boxes at the present time are commonly stayed, sealed er reinforced with cloth tape er wlth gummed kraft tape. I am also aware that lt has been proposed to reinforce paper in various ways by associating textile strands therewith. '1hus, 5 for example, in the patent to Angler 1,195,430, dated Aug. 22, 1916, there is disclosed a gummed stay tape for use on a box, reinforced by separate v textile strands extending across the same at rightangles to its length. Such strands serve to re'- 10 inforce the corner of the box. The diagonally disposed parts of the strand I! herein iilustrated similariy reinforce the -eomer of the box particularly because of their more nearly transverse disposition but have further advantages. The principal strain which might disrupt the strand is a bursting strain at the joint between the box parts which the stay bridges tending to split the tape along this joint. Since to provide a tape of indefinite length the grain oi the paper 20 must be longitudinal thereof, the stay is relatively frangible along such a line. With the tape reinforced with strands at right-angles, if the paper split the split would continue until lt encountered a strand. I1? the strain we1e suflcient to snap 25 this strand or to tear lt away from the soft,
lentous adhesive, Such as asphalt, which secured lt, the tear would continue er in eertain instances the split of the paper might continue along the grain without breaking the strand until a. sub- 30 stantial length of the paper closing the joint was ruptured although the edges of the box parts might still be secured together by unbroken strands. In the case of a stay such asherein disclosed, if the paper starts to split, when it 35 encounters a strand the tendency is to divert the tear along the strands into the areas of paper secured to the box parts at either side of the joint and there is less tendency for the tear 40 to be propagated along the joint in the manner described, and even lt the tear ums out to the edge of the tape along the line deflned by the reinforcing strand, the strength of the joint is relatively sli ghtly impaired. Furthermore, if the 45 reinfp'rcing strand is secured by a le ntous adhesive, such as asphalt, if a tear stnikes one of the transverse parts lt may draw a little through the asphali; on the bights er loops at the side tending absorb the shock and in fact the 50 strand without bursting may be pushed down toward the next lower strand in the direction of strain, tending to present two leng'ths of strand substantially together as a resistance to rupture and iurther propagation 015 the tear. 55
'Ihe stay strlp as descrlbed is readily und cheaply constructed and ls 015 substantia.lly unlform thickness about its area. I1: ls thus easy to handle, whether manually or mechanlcally, und easy to gum or meisten. As the edge portlons extend slightly beyond the relnforcement, they A are sea.led und the strand complehaly protected.
I am aware that the inventlon ma.y be embodled in other speciflc forms without departing from the splrlt or essential attributes thereof, and I therefore daslre the present emb0dl- 'ment to be consldered. ln ,all respects as illustrat.lve and not restrictlve; reference being ha.d to the appended claim rather than to the foregoing description to indicate the scope of the lnventlon.
