T all whom it may concern:

Be it known that I, DANIEL KELLEHER, a citizen of the United States of America, residing at Sandusky, in the county of Erie and State of' Ohio, have invented certain new and useful Improvements in Machines for Scoring Blanks of Cellular Board, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to the manufacture of scored blanks of cellular board designed for use in the manufacture of paper boxes and similar articles, and the invention comprises the novel means employed for scoring the stock which avoids overstressing or tearing the same and produces a score permitting the bending of the blank in opposite directions.

In the drawings: Figure 1 is a side elevation of the machine; Fig. 2 is a cross section thereof; and Figs. 3 and 4 are cross sections of the scored blank respectively bent in opposite directions.

My improved machlne comprises essentially a pair of traveling belts or endless members which are of a cross section to form on the one a tongue member'and on the other a complementary groove member. Thesev belts are arranged with their adjacent strands in slightly angular relation, so that at one end the tongue is in engagement with the groove while at the opposite end these members are separated topermit of the insertion of the stock.

In detail, A is, one of the endless belts traveling upon pulleys B and of a cross sec: tion having a projecting tongue portion C D is the complementary belt traveling over pulleys Band of a cross section forming the groove F. ,Upon opposite sides of this groove are portions G which are beveled on their outer edges and which are arranged opposite straight laterally-project ing portions H on the belt A on opposite sides of the tongue G. i

I are guides for the belts A and B to maintain the adjacent portions thereof straight.

The pulleys B and E are so arranged that the adjacent portions of the belts A and B are at one end 1n engagement with each other while at the opposite end they are slightly separated. This permits of feeding the cellular board in between the sepa- Specification of Letters Patent.

rated endsof the belt and during the movement ofthe stock with the belts the tongue C will be gradually forced downward into the groove F. This will first press down the cellular structure and then draw the material inward from each side. As the material is thus drawn in it is'forced' over the beveled faces G which also will ress down the cellular structure and will orm a reverse groove in the stock. Thus when the stock is removed it is formed with a central score deflected to one side and adjacent parallel scores deflected toward the other side as indicated atJ and K. This will permit of bending the blank in either direction without tearing or unduly stressing the stock.

. What I claim as my invention is:

1. A blank scoring mechanism comprising a pair of endless traveling members respectively having a tongue and a groove cross section, the adjacent portions of said members being in slight angular relation, with the tongue and groove in engagement at one end and slightly separated at the opposite end.

2. A blank scoring mechanism comprising a pair of endless belts having portions adjacent to each other and respectively of a tongueand groove cross section, pulleys over'which said belts travel relatively arranged to engage the tongue and groove at one end and separate them at the opposite end, and guides over which the adjacent portions of said" belts travel to hold the same from lateral displacement.

3. A blank scoring mechanism comprising an endless belt and an adjacentvmember having complementary tongue and groove cross sections, said members being relatively arranged to engage the tongue and groove at one end and to separate the same at the opposite end, the directly cooperating portions of the two members being substantially rectilinear.

4. A blank scoring device comprising a flexible traveling member having its cross section fashioned to form a score, a' guide for holding a portion of said flexible member straight, and an elongated cooperating member adjacent to the straight portionof said flexible member arranged to form a gradual tapering space therebetween.

5. A blank scoring mechanism comprising a pair of endless belts having straight portions adjacent to each other and respectively of a tongue andgroove cross section, the direction of movement of said straight portions being slightly angular with respect toeach other to engage said tongue and groove at one end and to separate them at the opposite end, and rigid guides for holding said adjacent belt portions from lateral displacement.

6. A blank'scoring mechanism, compris ing a flexible traveling member, and an adjacent cooperating member, between which material is fed, said members having engaged portions of tongue and groove cross section, the member formed with the tongue having flattened faces at each side thereof,

opposing beveled faces. formed upon the" other member at each side of the groove.

. 7. A blank scoring mechanism, comprising two adjacent members between which material is fed, having engaged portionsof 20 tongue and groove cross section, the opposing faces at each side of the tongue-and of the groove being respectively flattened and beveled.

In testimony whereof I aflix my signature 25 in presence of two Witnesses.
