That it is desirable to avoid the occurrence with each roller 20 and arm. 19, there is mounted on the bolt 18 a horizontally ex of marginal recesses or indentations in the tending contact arm 21, said arm extending sheet, as shown at 33, will be manifest, when parallel to the arm 16 of the bracket, and it is pointed out that if the sheet, were al 15 terminating below a contact point 22 mount lowed to advance between the scoring rollis, 80 ed in a transverse arm 23 secured to the the individual sticks 12 along the recessed.. bracket arm 16. Extending through the margin of the sheet will be imperfect, that end of the contact arm 21 is a contact Screw is to say, they will be irregular in shape and 24. The contact aim 21 is insulated from contain only a portion of the gum that a 20 the bolt 18 by means of an insulating sleeve perfect stick contains. Moreover, inasmuch which also acts to insulate the shaped as the sticks are handled and wrapped into arm 19 from said bolt 18. Spacing sleeves packages by mechanical means, it is mani are mounted on the bolt on either fest that the imperfect sticks would find their wav into packages, and as a result. de side of the contact arm 21. It is to be under stood that the device above described is the fective packages of gum would be placed same on both sides of the machine, so that on the market. It is clear that, by the pres there is a roller 20 which contacts with the ence of an alarm device which automatically sheet along longitudinal lines which deter Sounds when improper conditions are exist mine the lateral edges of the scored area of ing, the formation of defective sticks is thus 30 the sheet avoided. The devices located on opposite sides of The invention is hereinafter more fully the machine and in advance of the scoring set forth in the appended, claims. claim as my invention: 1. In a machine of the character described, the combination of a sheet scoring member, means for advancing a continuous sheet of material to said scoring member, a contact roller riding freely upon said sheet in ad vance of Said scoring member and in alime ment with a predetermined longitudinal score line of the sheet, and an alarm ar ranged to be operated by said roller upon the failure of the material to be present beneath the same In a machine of the character described, the combination of scoring rolls, means for rollis 7-7 form parts of an electric alarm circuit, preferably arranged as shown dia grammatically in Fig. 3, as follows: Conductors are connected with the arms of the contact rollers these conductor's being connected in parallel with a main conductor 28. Similarly, con ductors are connected with the fixed contact members 22-22, and are likewise connected in parallel with the main con ductor 28. Inserted in the circuit is an alarm bell 30, a switch 31, and a battery 32. The circuit thus arranged is open or broken under normal conditions, that is, when the contact points 22 and 24 of either alarm device are separated, and similarly the cir cuit is closed when these points are brought into contact, the closing of the circuit ener gizing the coil of the bel 30, causing the same to ring As shown in Fig. 2, the roller 20 is in contact with the sheet of gum 2, and in this position the contact points 22 and 24 are Separated thus So long as the sheet main tains a uniform width in passing beneath the rollers 20-20, the circuit will remain open. However, should the sheet be of a less width than the distance between the rollers 20-20, it is manifest that one or the other of the roller's will run off the sheet and drop down in contact with the plate 3. In Fig. 1 this condition is illustrated, in which the lower margin of the sheet is quite irregular, advancing a continuous sheet of materialbe tween said rolls, a contact roller riding freely upon said sheet in advance of said scoring rolls and in alinement with a pre determined longitudinal score line of the sheet, and an alarm circuit including nor mally separated circuit closing members, ar ranged to be brought into contact to close the circuit upon the failure of the material to be present beneath said contact roller. 3.
