All of paste-containing tank 6 in any suitable manthe rolls or rollers are journaled in a suitable ner.

Thelower one of at 5, to engage a pin or stud 7, mounted on 5 these, as shown in the drawings, is held down the end of the tank at some distance from its by a couple of springs located in the bottom front wall- These frame members extend of the paste-tank, while the upper roller is thence forwardly over the upper edge of the journaled in two arms movably mounted front wall of the tank and thence downwardly, no on the end frames. The device for indicattheir forward extremities resting on the table ing the predetermined length of strip is or other surface on which the apparatus is mounted on one extremity of the upper pasteplaced. As shown in the drawings, the two belt roll. frame members are connected by rods, (desigroll.

studs 15, which enter the central opening in the supply-roll ends. One of the standards 14 is slidably mounted on the rod 9 and is connected with a spring or elastic band 16, attached to a stop 17, fast on the rod. The device 16 has sufficient tension to hold the standard in operative relation with the supply-roll end. The object of this construction is to adjust the roll-holding standard to accommodate supply-rolls carrying paper of varying widths. The standards let are pivotally connected on the frame and are connected by springs 18 with the rearwardly-located rod 8, whereby the supply-roll is held in constant engagement with a tension-roller 19 as the paper is unwound and the supply-roll diminishes in diameter. The tension-roller 1D is journaled in the frame. In the rear of the tension-roller are located the two trimming-rollers (designated 20 and 21,respectively) between which the paper is drawn as it leaves the tension-roll. These rolls 20 and 21 are provided at both ends with cooperati'Tg cuttingdisks 22 and 23, which are slightly beveled to form cutting edges. disks trim the edges of the paper as the latter is drawn between the rollers 20 and 21. The roll 20 is divided and provided with two members 20, which are slidable on the spindle 24;. As shown in the drawings, the two end roll are adjustable, and each is connected with one extremity of a coil-spring 25, the other extremity of the spring being connected with a stop 26, adjustable on the spindle by means of a set-screw for regulating the tension of the spring. The tension of the three springs is so regulated that they have a tendency to draw the roll members 20 inwardly on the spindle, so that the cuttingdisks 22 thereon shall engage the cooperating disks 23 of the roll 21. It will be observed that the disks 22 and 23 slightly overlap each other. Hence when the length of the roll 21 is properly regulated the springs 25 draw the roll members 20 inwardly until their cuttingdisks 22 engage the cutting-disk 23, the tension of the springs being sufficient to hold the cutting-disks in operative relation. The roll 21 may have an extension-piece 21, placed upon the spindle between the cutting-disk 23 and the body of the roll, the part 21 being slidable 011 the spindle. The position of the disks 23 on the roll-spindle may be regulated by set-screws 27.

In Figs. 10 and 11 another form of construction. is shown for regulating the length of the In this form of construction the roll is designated 21 and is composed of a number of parts 21 which are movable on the rollspindle 21. Between these parts 21 are located coil-springs 21 which are normally under suflicient tension to cause the members disks is loosened for the purpose. In use the cutting-disk is moved on the spindle to regulate the length of the roll and fastened and the springs 21 expand to form spaces between the members 21. (See Fig. 10.) trimmings 28 (see Fig. 3) cut from the paper are guided downwardly by curved metal strips I 29, located at the ends of the roll 21 and adjustably mounted on the gage-plate 30,whereby they may be regulated to correspond with the length of the rolls 20 and 21. As shown in the drawings, the gage-plate is slotted longitudinally, as shown at 30. The strips 29 are fastened to the said plate by passing screws or bolts through an opening formed in the strip and through the slot 30. The bolt is fastened by means of a nut, whereby it is held in any desired position of adjustment. When it is not desired to trim the paper, these parts 29 may be moved outwardly on the gage-plate, so that they may not interfere with drawing the paper through the machine. I

In the bottom of the paste-carrying tank 7 is located a roll 31, which, as shown in Fig. 4, is held down by springs 32, attached to the tank and passing over the spindle extremities of the roll. This roll may, however, be loose and hold the bolt in place by gravity. (See Fig. 5.) It is thought that the springs may be preferable, since they permit the using of a roll of much less weight than is required where the roll is placed loosely in the tank for the purpose of maintaining the belt at the proper tension. Journaled in arms 33, pivotally connected with the frame members, as shown at 34, is a roll 35, which cooperates with the roll 31 and supports the belt 36, which moves through a quantity of paste in the tank. The arms 33 are provided with short lugs 33, which limit the movement of the arms 33 when the roll 35 is thrown rearwardly away from the roll 31 to disengage the belt 36 from the roll 21. (See Fig. 1.) The roll 35 is provided at each extremity with a disk 37 of larger diameter than the roll. Each of these disks engages a small pulley 38, mounted on the extremity of the spindle 21 belonging to the roll 21.

IIO

On one extremity of the spindle 35 0f the roll 35, outside of the disk 37, is mounted a cylindrical piece of wood 3, provided with an opening which fits over the protruding end of the spindle 35. In thispart 3 is inserted a short spindle part 3, upon which is made fast a small pulley 39. The parts 3 and 3 are arranged to be disconnected from the spindle extremity for convenience in assembling the mechanism. A bifurcated frame or yoke 40 straddles the pulley 39 and is provided with verticallyelongated openings through which the spindle'3 passes. J ourbelt, which is traveling '42, and when 1116 paper is pulled naled in the top of this frame is a pulley 42. The gravity of the frame normally holds the face of the pulley 42 in engagement with the face of the pulley 39, and to increase this pressure the lower extremity of the frame is provided. with a weight 13. The frame 40 is provided with ontwardlyproj ecting arms 44:, slotted to receive a cord 45, to one extremity of which is attached a weight 46. This cord is drawn through between the pulleys 39 and forwardly over the roll 21 (see Fig. 4) the pulley 39 is moved to allow the cord under the influence of its weight to move to indicate the length of the strip of paper, it being assumed that the weight is at its upward limit of movement when the operation begins. The length of the strip of paper is determined by measuring the first strip and making a mark thereon at the proper point. The strip is then wound on the roll 4: and drawn through the machine until the mark indicating the required length reaches the gage-plate 30, when the strip is cut off by the use of the disk cutter 4J7, journaled on a handle $8, the cutter following the groove 30 of the plate. Vhile the strip has been passing through the machine the weight 46 has moved downwardly a certain distance. A small clasp 48 is then attached to the cord in front as close to the roller 31 as possible. The cord is then pulled forwardly between the pulleys 39 and 42 until the weight 46 is raised to its upward limit of movement. The paper is again drawn through the machine until the cord has passed rearwardly between the pulleys far enough to bring the clasp 4:8 to its upward limit of movement, when the operator will know that the strip of paper in front of thc gage-plate is of the required length. The strip is then cut off and the operation repeated as long as the strips required are of uniform length. Every time the length of the strip is changed the first strip or length is measured and marked, as aforesaid, after which the measuring is automatic, as will be readily understood.

From the foregoing description the use and operation of my improved machine will be readily understood. The paper is first fed from the roll over the tension-roller 19 between the rolls 20 and 21 and then drawn upwardly between the belt 36 and the roll 21, and thence over the latter and across the gage-plate 30 at the top. of the paper operates the rolls, and the paper is brought into contact with the paste on the through the paste during the operation of the machine.
