CHARLES S. BIRD, OF EAST WALPOLE, MASSACHUSETTS.

Specification of Letters Patent.

Patented Nov. 23, 1920..

Application filed December 10, 1919. Serial No. 343,948.

To all whom it may concern:

Be it known that T, CHARLES S. BIRD, a citizen of the United States, residing at East Walpole, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Cover-Boards for Shingle-Bundles and the like, of which the following is a specification.

This invention has reference to means for bundling shingles and is adapted more particularly for use in connection with paper orfelt shingles, which, by reason of their nature, can not be as readily packed or bundled as can the ordinary wooden shingle.

The main object of the present invention is to provide cover boards, which boards are constructed in such manner as topreclude the cutting through of the binding wires employed to hold the bundle together.

The boards, of which there are two, one being im osed upon the lower and the other upon the upper face of the bundle. are preferablv formed of heavy, so-called fiber board. each board being produced from a single sheet of material, and preferably prov ded along the line of fold with a stay strip.

The invention is illustrated in the accompanving drawings, wherein:

Figure 1 is a pers ective view showing a complete bundle of shingles with the cover p rts n place;

Fig. 2 a perspective view on a somewhat enlarged scale of a portion of one of the cover boards with one of the flaps turned outwardly;

Fig. 3 a similar view as seen from the opnosite side with both of the flaps turned inwardly; and

Fig. 4 a erspective view of a modified o m of board.

The up er and lower boards are alike in form and hence a description of one will snfiice and the same reference numerals are applied to each.

Having reference to Figs. 1 to 3 inclusive. the board. so-called, is formed from heavy. fiber board and comprises a main bod portion 1 and two inturned flaps 2 and 3. The stock from which these boards are formed is preferably run through a creasing or indenting machine which forms a pair of parallel creases 4 in the stock, the creases being spaced apart a distance equal to the length of the shingle, that is, the length from the butt to the tip of the shingle. The stock from which the boardsare formed may be in a continuous length and cut up to form boards of the required dimensions, or a length equal to the width of the shingle which go to make up the bundie, or separate pieces of stock of the proper dimensions may be creased or indented. Preferably, there is applied to the stock, along the lines of indentation, a strengthenmg strip, as of cloth or tough and heavy paper, as indicated by 5. By indenting the stock as shown there will be formed a beaded portion along opposite edges of'the board. which beaded edges not only protect the ends of the shingle, but also assist in preventing the fastening wires 6 from cutting through the board. In other words, the provision of the bead and the strengthening or stay strip 5, produces a marginal portion which is somewhat thickened. and, as just noted, such construction prevents the fastening elements or wire from cutting through and injuring the shingles which are held between the boards in bundle form. The present structure is advantageous over the usual wooden boards in that the latter are expensive, and. moreover, are apt to split. The present binder or board may likewise be readil prin ed on so that one look ng at the board would he informed as to the contents of the bundle. both as to co or. form of shingle and quantity w ich the bundle contains. and l ke data. which is of service both to the shipper and purchaser.

l'n Fin. 4 there is shown a slightly modified construction wherein the crease or fold takes a, sliqhtlv d fierent form from that shown in the other figures. As will be seen the beaded ed we. denoted bv 7. proiects only to one side of he main body of the board and not in both directions. as in the other form. It is to be understood that any form of indenting or creasing which will produce a bead along the edge falls within the spirit and scope of the invention, and the cla ms are to be construed with this in-view.

What is claimed is.- I

1. A binder board for shingle bundles and the like, formed from a heavy sheet of fiber board with two of the opposite marginal sections of the board infolded upon the body of the board thereby producing a sublth stantial edge along the line of fold whereby a binding wire or the like will under normal conditions be prevented from cutting through the hoard.

2. As a new article of manufacture, a binder board for shingle bundles and the like, comprising a single sheet of heavy fiber board creased along two parallel lines from end to end with the face portions outside of the lines of creasing turned inwardly upon the central portion, thereby tornuing beaded edges along the lines of told.

3. As a new article of manufacture, a binder board for shingle bundles and the like comprising a single sheet of fiber hoard creased along two parallel lines from antenna end to end with the face portions outside of the lines of grooving turned inwardly upon the central portion thereby torming beaded edges along the line of told, said beaded edges being protected by a stay strip secured thereover.

4t. A binder board for shingle bundles and the like formed of a heavy sheet of fiher board with two of the opposite marginal sections ofthe-board intolded upon the body of the board producing a beaded edge along the line of told, with a stay strip secured upon said headed edge.

ln testimony whereof I have signed my name to this specification.

CHARLES S. BIRD.
